Xin' anjiang tour guide words

The leading word of Xin 'anjiang is 1. Dear tourists and friends, now we are going to visit Xin 'anjiang Hydropower Station. As our visiting area is also a production area, please observe the visiting rules. No smoking, no taking pictures and no touching the equipment in the factory. Please follow our tour route. Thank you for your support and cooperation.

Dear friends, this is the generator room of the hydropower station. The workshop has a total length of 2 16m, a width of 17m and a height of 42.75m There are 9 generator sets installed in the workshop, all of which are manufactured by Harbin Electric Machinery Factory. The original total installed capacity is 662,500 kilowatts. After the expansion of the generator set in our factory from 1999 to 2003, the current total installed capacity is 8 1 10,000 kilowatts, and the maximum output can reach 855,000 kilowatts in a short time. This is the No.4 generator set, which is the first self-designed and manufactured hydroelectric generator set in China. On April 22nd 1960, this unit was the first to generate electricity. We see that the cylindrical rotor in the middle of this generator is the main shaft of the generator, which rotates 150 times per minute, and each rotation can generate about 10 kWh of electricity.

In fact, the power generation principle of hydropower stations is very simple, that is, power is generated through the water level difference between upstream and downstream. Xin 'anjiang Hydropower Station has a drop of 70 meters. There are nine water diversion steel pipes between the dam and the powerhouse, which are 93 meters long and 5.2 meters in diameter, and have the water delivery capacity of 1 17 cubic meters per second. They lead the water from the upstream reservoir to the turbine, impact the blades of the turbine, drive the rotor to rotate, and then interact with the exciter at the upper end of the generator to generate current. ...

Now look at this huge oil painting on the wall next to Unit 4. This was created by China famous painter Chen Ninger in the late 1970s. This oil painting depicts Premier Zhou Enlai inspecting Xin 'anjiang Hydropower Station. That was April 9, 1959. After the Seventh Plenary Session of the Eighth Central Committee of Shanghai, the beloved Premier Zhou rushed to the construction site for inspection. The cordial care of the Prime Minister greatly inspired the courage of the builders. Standing on the left of the Prime Minister is Comrade Wang Xing, director of the Engineering Bureau in charge of power station engineering at that time. Before leaving, Premier Zhou personally wrote an inscription for Xin 'anjiang Hydropower Station: "Cheer for the success of the first large-scale hydropower station with self-designed and self-made equipment in China!" Now these 3 1 Chinese characters are embedded in this wall, which looks solemn and profound.

In addition to the beloved Premier Zhou Enlai's inspection of Xin 'anjiang Hydropower Station, several generations of party and state leaders such as Dong, Ye Jianying, Li Xiannian, Zhu De, Haibo, Qiao Shi, wjb and Jia Qinglin have been here successively, and many foreign heads of state such as Ho Chi Minh and Sihanouk have also been here ... The care and attention of many leaders further embodies the glory and brilliance of Xin 'anjiang Hydropower Station. Famous domestic artists, writers, scientists, etc. More people come here to visit and tour.

Dear friends, we are standing on the top of Xin 'anjiang Hydropower Station at an altitude of 1 15 meters, and let's get to know some commonly used equipment in power stations first. Let's look at the huge building at the top of the dam. This is called a ship lift, also called a lock. At that time, it was designed and built to facilitate the connection between upstream and downstream ships. It was originally planned that the upstream ship could slide downstream through the slideway, and the downstream ship could be hoisted to the upstream reservoir by crane. However, due to the lack of funds and technical strength at that time, the slideway was not built and the crane was not installed. Although these conditions have been met today, it is of little significance. Now it is only used as a ship stop. Look at the railing in front of us. This is the spillway. There are nine in total, which are designed and built for the safety of the dam. This one in the middle is the sluice. Its width is 13m, its height is 10.5m, and its weight is 30 tons. Combined with the water pressure of high water level when the reservoir behind exceeds 105m, the total weight can reach 130 tons. Two large portal cranes, commonly known as portal cranes, are installed on the dam crest, each with a lifting capacity of 160 tons. Its main function is to lift the gate during flood discharge. Why do you want to install two? Because the gate must be lifted symmetrically when it is opened. If gate 1 is lifted here, then gate 9 must be lifted there. Otherwise, the dam will be deformed by strong water pressure. The maximum warning water level of this dam is108m above sea level, because if the water level of the upstream reservoir exceeds108m above sea level, there will be two hazards: First, many villages and towns and farmland in Shexian County, Anhui Province and Chun 'an, Zhejiang Province will be flooded, which will bring losses to people's lives and property; Second, the dam could not bear such a large water pressure, which led to the collapse of the dam, thus making the downstream banks of Fuchun River and Qiantang River become Wang Yang. Therefore, whenever the water level of the reservoir reaches about106.5m above sea level, Zhejiang Flood Control Headquarters will send people to Xin 'anjiang Hydropower Station to closely observe and analyze the water regime. If the water level rises to the altitude of107.5m again, it is necessary to consider opening the floodgates for flood discharge. However, flood discharge is a very unwilling thing for Xin 'anjiang Hydropower Station. First of all, water flow is the resource of power generation, and the water level in the reservoir area must be kept at a certain height to generate huge potential energy. It would be a pity if it is lost because of flood discharge. Secondly, every flood discharge, the downstream flood discharge areas-jiande city and villages along the river, as well as Tonglu, Fuyang and other low-lying areas along the river will be flooded, resulting in farmland damage and property losses. Therefore, although Xin 'anjiang Hydropower Station has been built for more than 50 years, only six floods have occurred, namely 1966, 1983, 1994, 1995, 1996 and1996. The first time was in July 65,438+0966. Whenever you open the floodgate, you can see that the Qiandao Lake merged into a huge water dragon, spewing out from the spillway, surging down the spillway as high as 100 meters, quickly dispersing to form a huge waterfall, spewing out more than 300 meters, and then pouring heavily on the downstream river, churning up huge spray. Spectacular scenes far exceed all the existing natural waterfall landscapes in China, and visitors are all amazed and feel the greatness and magic of people's creativity. At that time, the water level of the reservoir was 103 meters above sea level, and all nine gates were lifted, which was the only 9-hole flood discharge so far. The flood discharge lasted for five days, and the water level of the reservoir dropped 1 m. The flood discharge also caused the pier of the bridge in front of the dam to move forward and become a dangerous bridge, which can only be used by motorcycles and pedestrians. The second flood discharge was on June 28th, 1983. At that time, the water level was as high as 107.76 meters above sea level. The maximum flood discharge is 7 holes and the minimum is 1 hole. After half a month of intermittent flood discharge, the water level only dropped by 0.5 meters. At that time, there was mist within 3 miles, and the road leading to Hangzhou was blocked for 3 days and 3 nights. Up to now, the latest flood discharge was on June 30th 1999, which is also the highest water level in history, reaching an altitude of108.368m.. This time, the floodgate was opened for 8 times, which lasted for 7 days. After understanding the function of overflow Hong Men, let's take a look at this side. The three large equipments lined up are transformers of the power station, because the current and voltage generated by the generator set are only 13800 volts. In order to ensure long-distance transmission, it is necessary to boost the voltage to 220,000 volts through a transformer and then transmit it to East China Power Grid.

Dear friends, we stand at the top of the dam and overlook the surrounding area. Please look east, you can see the green hills are continuous, the iron tower is towering, a river and clear water meander eastward ... Then please look west, and you can see Gaoxia Pinghu, dotted with islands. This is the artificial lake formed after the completion of Xin 'anjiang Hydropower Station-Qiandao Lake.

Qiandao Lake is the nickname of Xin 'anjiang Reservoir, and it is named because there are 1078 islands in the reservoir. Qiandao Lake covers an area of 567 square kilometers, equivalent to the land area of Singapore. It is the largest artificial lake in East China, 88 times larger than the West Lake in Hangzhou. Its water storage capacity is 654.38+078 billion cubic meters, four times that of Taihu Lake and more than 0.3000 times that of Hangzhou West Lake. Walking along its coastline, a 60-horsepower motorized sailboat takes half a month. At present, Qiandao Lake is a national 5A-level tourist area.

Qiandao Lake is owned by Jiande, Chun 'an and Shexian in Zhejiang and Anhui provinces, of which Chun 'an accounts for 93.6%, Shexian accounts for 4.4% and Jiande accounts for 2%. Qiandao Lake is currently divided into five lakes, namely central lake, southeast lake, southwest lake, northeast lake and northwest lake. Tourism resources are mainly concentrated in the middle of the lake and the southeast lake area. It is convenient to visit osmanthus island, Mishan Island and Tianchi Island in the southeast lake area from Xin 'anjiang Hydropower Station. Qiandao Lake in Jiande area has also been developed. Known as "the first island at the entrance of Qiandao Lake", Lucky Island faces Xin 'anjiang Hydropower Station across the lake, and Tongguan Gorge scenic spot next to Lucky Island has also been developed, now called Lover Valley.

If you have time, you can go sightseeing in Qiandao Lake.

Dear friends, Xin 'anjiang Hydropower Station has been written into textbooks and printed on stamps. Today, we look at it with reverence. I believe that the majestic Xin 'anjiang Hydropower Station will leave a deep impression on you. I hope everyone can do better publicity and promotion for her, let more people know this monument in the history of hydropower construction in China, and understand the struggle spirit of the older generation of builders who are not afraid of difficulties and self-reliance.

Today's tour is over, thank you. I wish all my friends a pleasant journey!

My hometown Xin 'anjiang, located in the south of the motherland, is a small town in the south of the Yangtze River. This is a magical and beautiful place.

When it comes to Xin 'anjiang, people will think of Li Bai's poem: "Ask Xin 'anjiang, what do you know?" "In the pedestrian mirror, bird screen. "Today's Xin 'anjiang is famous for its clear water, cool air and strange fog.

The water in Xin 'anjiang is amazing! The river is so clear that you can see fish and shrimp at the bottom of the river and sand algae sinking at the bottom of the river. This river is really green, as if it had been dyed by green hills, trees and grass. The most amazing thing is the water that is warm in winter and cool in summer. Why is winter warm and summer cool? This has to start with the Xin 'anjiang Hydropower Station completed in 1965.

After the completion of the hydropower station, the upstream became the famous Qiandao Lake. The lake with a depth of more than 70 meters flows out from the bottom of the dam, which keeps the river at 12℃ ~ 14℃ all the year round.

The wind in Xin 'anjiang is even more unique. In summer, although the heat is unbearable, as soon as you approach the river, a refreshing coolness will come to your face and make people feel refreshed. So every summer evening, old people, children, young men and women love to come to the river for a walk, enjoy the cool, play and frolic. ...

The fog in Xin 'anjiang is the most charming. The magical "white sand strange fog" is even more indescribable. In the early morning, the drizzle is hazy, white fog is curling by the river, and there are canoes and bamboos on both sides of the river, which are unobstructed on the green water. Standing on the Baisha Bridge, look around: Shili fog belt hangs over the river like a veil, floating among the peaks, and the hidden green hills, trees and grass are inadvertently sticking out. The mist after the rain hangs over the river like a thin gauze, as if quietly caring for the beautiful and holy Xin' an River water. Usually, people can only enjoy the foggy scenery on high mountains, but it can be seen everywhere in our Xin 'anjiang River. In the evening, the bloody sunset glow is reflected in the thin milky fog on the river, as soft as gauze and moonlight ... making people linger.

This is our beautiful, magical and energetic Xin' anjiang; This is our mother river; This is my hometown. I love my hometown!

Hello, everyone, today I will lead a team to visit Xin 'anjiang, the hometown of mountains and rivers. My surname is Wang. You can call me Wang Dao.

Xin' anjiang is located in the upper reaches of Qiantang River, also known as micro-port. The main stream is 373 kilometers long, surrounded by green trees and ginkgo trees, and the breeze blows from one side, which is refreshing.

Come on, let's go to the river. Look! This is Xin 'anjiang, look! Do you know the temperature of this clear and overflowing river? Look, the people over there only walked barefoot in the water for a few minutes. Xin 'anjiang has the characteristics of warm winter and cool summer, attracting countless people from all over the world to experience it.

Next, let's walk along the path. Look! This is Baisha Bridge. Baisha Bridge was built in1992,65438+10, with a length of 362m and a height of 24m. The main bridge has a total of 6 spans, and the specific arrangement is "10 span 30m+1span 50m+1 span 90m+1 span". The upper structure is "D"-shaped. There are 256 lions on the bridge, with different expressions and lifelike. Lions don't have those two. They are the same.

The most famous is strange fog. Before dawn in the morning, the white mist enveloped the Xin 'anjiang River, as if it were covered with gauze. Several ships are looming, the lighthouse is flickering, and if you are lucky, you can see carp shuttling between algae.

The trip to Xin 'anjiang will come to a successful conclusion here.

Dear friends, Hello everyone! Welcome to visit Xin 'anjiang Hydropower Station. My name is X, and I am the tour guide who accompanied all my friends on this trip. Today's tour is to visit the dam appearance, power plant, dam gallery and elevator leading to the dam top, then visit the observation deck at the dam top and overflow Hong Men, and finally return to the ticket gate along the original road. Our tour lasted about an hour. First of all, I wish you all a pleasant journey today.

[Summary] Commentary point: in front of the dam/besideNo. KLOC-0/post.

Xin 'anjiang Hydropower Station is located between Tongguan Gorge, four kilometers west of Xin 'anjiang River. It is the first large-scale hydropower station designed, equipped and installed by itself in China, which is a milestone in hydropower construction in China. /kloc-0 was completed in April, 1957, and/kloc-0 officially started generating electricity on April 22, 1960. The whole project was basically completed in only three years, creating a miracle in the history of hydropower station construction in the world.

Xin 'anjiang Hydropower Station planned to invest 500 million yuan, but actually only used 423 million yuan. This also includes 298,000 immigrants from Chun 'an and Sui 'an counties in the reservoir area, and the resettlement fee alone cost 80 million yuan. Therefore, the actual investment of the project is only 3,465.438+0 billion yuan. After the completion of the power station, it took only four years to recover all the investment. So far, the profits paid by Xin 'anjiang Hydropower Station can be invested in the construction of 13 hydropower stations of the same scale. The construction of Xin 'anjiang Hydropower Station is the key project of China's first five-year plan, which has received strong support from the people of the whole country. More than 20,000 scientific and technical personnel and workers to build hydropower stations were transferred from Changchun, Xiaofengman and Guanting Reservoir in Hebei and Beijing, Shanghai, Sichuan and Jiangxi in the northeast. The building materials of the power station come from all directions of the motherland. The heart of the power station-the hydro-generator set comes from Harbin Electric Machinery Factory in Heilongjiang Province, and hundreds of thousands of tons of cement are mainly from Jiangnan Cement Factory in Nanjing, Jiangsu Province. In the whole construction process of the power station, * * * has completed 5.4 million cubic meters of earthwork, 40,000 tons of practical steel, 360,000 tons of cement and 0/36,000 cubic meters of wood/kloc. For example, if 100 4-ton Jiefang cars are used to transport the 360,000 tons of cement, it will take nine years to transport it from Nanjing to Xin 'anjiang. So for convenience, a 55.54-kilometer Lanzhou-Tongguanxia railway was built on the other side of the river, and it took 6,000 railway wagons to transport all the cement. This railway line has been used ever since. At that time, the concrete consumption reached 1.6 million cubic meters, and a building with 15 floors could be built. The earthwork consumption is 5.4 million cubic meters, and the roadbed from Xin 'anjiang to Beijing can be built with width 1 m and height 1 m..

At present, the annual output of Xin 'anjiang Hydropower Station is 65.438+0.86 billion kWh, ranking 654.38+0.6 in the national hydropower station ranking. Although its power generation ranking is no longer the first, its historical position in the history of hydropower in China will always be the first. Xin 'anjiang Hydropower Station mainly generates electricity, and has many functions such as irrigation, flood control, shipping, tourism and aquaculture. At present, with the development of China's power industry, it mainly plays the role of peak regulation, frequency modulation and emergency standby, and plays the role of cascade compensation for Fuchunjiang power station downstream.

After the completion of Xin 'anjiang Hydropower Station, 1963, Premier Zhou personally instructed Xin 'anjiang Hydropower Station as a window for the success of China's socialist modernization, allowing relevant people at home and abroad to inspect and visit. Previously, it was mainly based on internal reception. Since 1980, Xin 'anjiang Hydropower Station has been officially established as a tourist attraction.

Open outdoors. In the past 30 years, it has received more than 2 million Chinese and foreign tourists. Now it is a national industrial tourism demonstration site, a national red classic tourist attraction and a patriotic education base in Zhejiang Province.

Some people may ask: Why did China build the first large-scale hydropower station here? There are many reasons for this.

First of all, Xin 'anjiang is rich in hydropower. In ancient times, Xin 'anjiang was a turbulent river with many canyons, rapids and rapids. "Beach after beach, beach is ten feet high, 360 beaches, Xin 'an is in the sky" and "rapids and dangerous beaches, ten thousand turn out of Xin 'an" and other ancient poems are the true portrayal of Xin 'anjiang. There are so many rapids and rapids, which are not conducive to shipping, but contain huge hydropower. This is the foundation for the construction of large hydropower stations, especially in Tongguanxia area, with large drop and good geological conditions;

Secondly, Xin 'anjiang is only over 400 kilometers away from Shanghai, the largest industrial city in China, and the power transmission is relatively convenient. Building a large hydropower station here is a major breakthrough in solving Shanghai's energy shortage;

Furthermore, as early as 1947, the Qiantang River Hydropower Survey Institute under the Resources Committee of the Republic of China sent a group of experts and scholars to carry out social investigation, topographic and geological exploration and hydrological data collection in Xin 'anjiang River basin, and compiled the Zhejiang Water Conservancy Implementation Plan, which put forward the three-level development plan with the total installed capacity of120,000 kilowatts for the first time. Especially the proposal to build 80,000 kW hydropower station in Xin 'anjiang, but for various reasons, the hydropower station still cannot be built ... After the establishment of People's Republic of China (PRC), to solve the energy shortage problem in Shanghai, the construction of hydropower station in Qiantang River basin was put on the important agenda of the party and the country. On the basis of 1947 survey report, the expert group organized by the new China government submitted a report on the construction of Xin 'anjiang Hydropower Station to the State Council after four years of field survey, investigation and full demonstration. Finally, in June of 1956, the State Council officially approved the construction of Xin 'anjiang Hydropower Station, the first large hydropower station in China, in Tongguanxia, Jiande County, Zhejiang Province. The hydropower station has good geological structure and narrow river surface.

Xin 'anjiang Hydropower Station is mainly composed of dam, generator room and step-up switch station. The building you see now is the river dam. River dam, also known as wide joint concrete gravity dam, means that it is made of concrete and steel bars and is a hollow dam. The invention has the advantages of material saving, thermal expansion and cold contraction, and convenient maintenance. As you can see, it is an inverted trapezoid with a width of 97 meters and a total length of 466.5 meters at the top. The dam foundation below is 315m, and the dam height is105m. Its altitude is115m, and the relative height from the road surface to the dam crest is 8 1 m. Everyone can't see its height now, because its shape is inverted trapezoid, which gives people an illusion visually. When we reach the top of the dam, we can see its height from above. You can see that there are nine holes in the dam, which are the flood discharge holes of the dam. The design similar to wall battlements under the spillway tunnel is built to buffer the water flow speed during flood discharge. The whole high dam is designed according to the once-in-a-thousand flood, which has passed the once-in-a-thousand flood test.

Now, please look halfway up the mountain, which is the switching station of the hydropower station. Its function is to adjust the current and voltage, and send the generated current out through the power grid.

The main function of Xin 'anjiang Hydropower Station is to generate electricity. But in fact, the construction of Xin 'anjiang Hydropower Station has brought many changes to the regional economy and industrial layout.

First, a new city, Xin 'anjiang City, was formed. The former Jiande County is more than 30 kilometers away, in the lower reaches of Xin 'anjiang River, an ancient town with a long history of 1800 years, which used to be Jiande County and Yanzhou.

Government offices. When Xin 'anjiang Hydropower Station 1957 was built, more than 20,000 construction workers from all over the country gathered in Baisha Village, with only 20 fishermen, which obviously could not meet the construction requirements of this large hydropower station. Therefore, on 1960, after the first unit of Xin 'anjiang Hydropower Station was officially put into power, with the approval of the State Council, Jiande County Government moved the county seat from Meicheng Town to this place. After 50 years of construction, a desert has become a new tourist city-Xin 'anjiang City. Now it has many honors and auras, such as National Health City, China Excellent Tourism City, China Green Model City, China Top 200 Charismatic Cities, China Top Ten Xanadu Cities, East China Top Ten Tourism and Leisure Cities, China Top Ten Leisure and Livable Ecological Cities, etc.

The second is to improve the local microclimate and natural environment. Due to the interception and storage of water by the dam, a large reservoir with an area of 573 square kilometers was formed in the upper reaches. Due to the regulation of the reservoir, Xin 'anjiang City has formed a unique microclimate. "Clear water, cool air and strange fog" are the "three wonders" of Xin 'anjiang at present. Look, how clear the water is flowing from under the dam. Its visibility can reach seven meters, reaching the national first-class drinking water standard without purification. At present, Nongfu Spring, which tastes a little sweet, is filled with this kind of water after purification. The factory building of Nongfu Spring is built on the other side of the river 2 kilometers away from here. The sweet and refreshing Xin 'anjiang "70 17" beer is also made from this water through scientific processing. Now jiande city is a famous natural drinking water production base in China, thanks to the completion of hydropower station. Xin 'anjiang water is not only clear, but also maintains a constant temperature of about 17℃ all the year round. Influenced by this constant temperature water, Xin 'anjiang is warm in winter and cool in summer, especially in summer, Xin 'anjiang has become an excellent leisure and summer resort. At present, Jiande's tourism slogan is "Cool Water World, Dream of Xin 'anjiang", and "17℃ Xin 'anjiang Cool Tour" is launched every year, which is closely related to Xin 'anjiang Hydropower Station. Influenced by Xin 'anjiang, river fog pervades Xin 'anjiang all year round, and "Strange Fog of Xin 'anjiang" has become a famous landscape in China.

Thirdly, Xin 'anjiang was blocked by the dam of hydropower station, which formed a huge reservoir in the upper reaches and created the world-famous Qiandao Lake. About Qiandao Lake, I will introduce it to you when we get to the top of the dam. In a word, the construction of Xin 'anjiang Hydropower Station plays an important role in China's social and economic development.

Today's tour is over, thank you. I wish all my friends a pleasant journey!

My hometown Jiande is located in the west of Zhejiang, where there is a beautiful Xin 'anjiang River.

From 65438 to 0957, after the completion of the first large-scale hydropower station designed and built by our country, Xin 'anjiang changed from a swift river into a clear and transparent river, just like a beautiful fairy flying eastward in a white gauze.

I live by the Xin 'an River, where the back mountain is surrounded by water and green trees, and the buildings built on the mountain are scattered and orderly. The riverside park in front of the community 10 kilometers is very beautiful.

We walked into Jiang Bin Park, where there were roller coasters, trampolines, treadmills, wooden bridges and other sports equipment, and colorful neon lights flashed at night, which was very eye-catching and beautiful. It is particularly worth mentioning that the park faces the river, and the water in Xin 'anjiang is crystal clear all year round. In spring, Xin 'anjiang suddenly opens up, and looking around the river will make you relaxed and happy. In summer, the river is cool and cool, and it is biting cold as soon as you step into the water, which ensures that you will flee ashore in less than a minute and sit on the shore and blow the cool breeze, which is particularly comfortable; In autumn, the river is printed with golden reflections on both sides, which is as beautiful as a paradise on earth; In winter, the river braves warm white air, white waves, pieces and rounds, which are very beautiful. Playing by the river will make you feel no chill, as if you forgot it was winter.

My hometown is so beautiful, don't you want to see it? Remember to come and play when you pass by!
