Jianyukou - the urban water supply pipeline in the urban area of Weinan, was built in the early part of this century. Since its completion, the project has been undertaking the main task of domestic water supply for urban residents in Weinan City.

The source of the project comes from the Jianyukou Reservoir in Qinling Mountain, which has an average altitude of more than 2,000 meters. Passing through Qiaonan Town, Chongning Town, Linwei District, Linewang Township (now merged into Chongning Town), Fengyuan Town, Xiangyang Office, Zhannan Office and other places, enter Weinan City. The total length of the project is more than 30 kilometers. Among them, Beilei Village, Fengyuan Town, is about 5 kilometers away from Xizhang Village, Xiangyang Office, passing through the majestic and stretching Longwei Slope, and pouring directly into the rapidly developing urban area of Weinan. The difference between the upstream and downstream water levels is about 300 meters, and it is pregnant with very rich kinetic energy. If it can be used, it will certainly create a lot of resources for the country.

For this reason, I believe that as long as there is a continuous supply of water to the pipeline, it is perfectly possible to build a small hydroelectric power station in the pipeline.

The hydropower station is very easy to build and environmentally friendly, without any environmental pollution and without affecting the city's water supply.

The following is the construction method of the hydropower station designed by me, which is for reference only. Whether it can be realized or not remains to be designed by relevant experts after specific research and discussion.

First, choose a suitable address. The location of the power station should not only be convenient for transportation, but also easy to connect to the national grid for operation. Therefore, I believe that the site of the hydropower station should be selected to build the power station south of the Longhai Railway, north of the garbage station, and next to the water supply pipeline near the Weiqiao Highway.

2. Excavation. Once the site has been chosen, the first step is to dig up the underground water supply pipes. Then install a tee and a valve on the underground pipeline (the main function of this valve is during the construction of the power station and when overhauling the power generation equipment, after opening this valve, the underground water supply can directly enter the water supply pipeline without passing through the power station, and does not affect the urban water supply) Then, through the tee in front of the valve, the underground pipeline is introduced into the ground. Then several turbines and generators are connected in series on the pipeline in turn, and electricity can be generated (the power of the generator and the diameter of the input water supply pipeline should be reduced step by step) If there is no special water turbine, a centrifugal water pump can also be used instead of a water turbine. By using the reverse operation of the centrifugal water pump, the generator can be driven to generate electricity.

3. Pooling. In order not to affect the city's water supply, and to ensure that the generators have a continuous and stable power output, a reservoir (or a water tower) needs to be built, one end of the reservoir is connected to the generator set, and the other end is connected to the original underground water supply pipe. The main function of this pool is to regulate the amount of water consumption in the city.

4. Circular power generation. In order to ensure a continuous, stable power output from the generator, the pipes passing through the generator need to continuously drain water into the reservoir, which is very limited in volume. Therefore, it is necessary to install one (or two, one for backup) large water pump next to the reservoir, and when the water level in the reservoir exceeds the warning water level, the pump will be automatically started to pump the water in the pool back to the pipe in front of the generator and circulate power generation again. (Another method is to re-install a new pipeline, which will pump the water directly to the top of the Longwei slope through the pipeline, and then inject it into the original underground pipeline to recycle power generation again.) )

5. Operational grid connection. After the completion of the power station, it will also need to be connected to the national grid (or can be operated independently), so it will also need to install some transformers and some other ancillary power equipment.

After the completion of the hydropower station, it will be an environmentally friendly power station that is both energy-saving and environmentally friendly, and has no pollution. The project can not only be integrated into the national grid for operation and power generation, but also can generate electricity independently, alleviate the impact of national power shortage, and drive the take-off of the industrial economy. With broad prospects, and a bright future.

My home is in Weinan, where is the longevity plateau...... Which apples and wheat are there...... Whenever I hum a song composed by myself based on the Northeast Duo and come to Weinan, I will see a majestic and rippling reservoir in the distance - Youhechuan Reservoir.

The reservoir is located at the south gate of Weinan, 5 kilometers southwest of Jiangjia Village, Xiangyang Office, Weinan Urban District. This reservoir was built in the early 50s of the last century, and is a comprehensive water conservancy project that focuses on urban water supply, taking into account flood control and agricultural irrigation.

Since its completion, the project has played a great role in urban water supply, farmland irrigation, and urban flood control in Weinan City. It has achieved very rich social and economic benefits.

In recent years, with the rapid economic development of Weinan and the continuous development and growth of the city, the demand for urban water supply has gradually become increasingly serious. In addition, the drought and lack of rain in recent times have caused serious waste of water for production and domestic use in enterprises, resulting in insufficient water storage and seriously affecting the quality of life of the general public. It has become an urgent problem to be solved in the urban area.

The difference is that less than 30 kilometers from the reservoir there is also a Jianyu reservoir. The reservoir is located within the boundary of Gaotang Town, Huazhou District, at the junction of Wei (Linwei District) and Hua (Huazhou District).

The reservoir was built in the early 70s of the last century, and after ten years, hundreds of thousands of human and material resources have been used. It was not until the early eighties of the last century that operational work began on the project.

In my childhood memories, when this project was being built, it coincided with the middle of the day. In our local area, almost every production team was assigned to participate in the construction of the project.

Most of the male villagers in our village who are over 60 years old have participated in the construction of the reservoir. At that time, due to my young age, I regretted that I could not witness the production scene of the project construction with my own eyes.

In the early stage of construction, the reservoir had a very important role in changing the local production and living conditions. In recent years, due to the gradual reduction of water sources in the reservoir area and the gradual increase in the pressure of domestic water, the reservoir area has become the largest production and domestic water supply base in the city.

The reservoir area is located within the boundary of Gaotang Town, Huazhou District, at the junction of Wei (Linwei District) and Hua (Huazhou District). The scenery here is beautiful, the mountains and rivers are beautiful, the water source is very abundant, and the water quality is very clean.

In recent years, the reservoir area has not only become a tourist mecca, but also the largest water supply base in Weinan City. The annual water supply is as high as 22.55 million cubic meters, of which the urban water supply is as high as more than 13 million cubic meters. It accounts for more than 60 percent of all water supply in Weinan City.

The water supply pipeline from Jianyu to Weinan City, built in the early part of this century, is one of them. The project is more than 30 kilometers long, passing through Gaotang Town, Huazhou District, as well as Qiaonan Town, Chongning Town, Linwei District, Xianwang Township (now merged into Chongning Town), Fengyuan Town, Xiangyang Office, Zhannan Office and other areas, and entered the urban area of Weinan.

The pipeline supplies more than 6 million cubic meters of water annually. Among them, Beilei Village, Fengyuan Town, to Xizhang Village, Xiangyang Office, about 5 kilometers, through the magnificent, continuous Longwei Slope, its upstream and downstream water level difference of more than 300 meters, which breeds very rich kinetic energy. It's a pity that it has not been used.

With the continuous development of reform and opening up, the economic outlook of our Weinan City has shown rapid development and changes. Cities are also growing in size.

As cities continue to grow in size, so does the demand for electricity.

Especially since the recent interruption, the city has successfully realized the reform of coal power. As a result, the demand for electricity has become even hotter. With the continuous growth of electricity demand, emerging industries such as new energy development, small-scale power generation, and distributed photovoltaic power generation have also become hot topics and have become the object of development and research by people of insight.

In view of the unique favorable conditions of the water supply pipeline from Jianyu to Weinan, I boldly conceived the strategic ambition of "leading the stream into You". After the construction of the project, it can not only solve the impact of insufficient water supply of Youhe Reservoir, but also play a role in power generation, water supply, irrigation, water storage and adjustment of stored water as one of the projects to benefit the people. After the construction of the water conservancy project, only the following two steps are required:

1. Change the pipeline. In order to build a project that can generate electricity without affecting the city's water supply and irrigation, it is necessary to change the way the downstream pipeline is delivered. Personally, I think the water supply pipe should be disconnected from the vicinity of the Longweipo garbage treatment plant, and then the water supply pipe should be introduced into the Youhe reservoir. The downstream water supply pipelines can be completed by changing the water supply from the Youhe Reservoir. (Some changes may cause a reduction in the water pressure of the downstream waterworks, and some of the waterworks pressure equipment needs to be changed.) ）

2. Construction of power stations. Once the pipeline diversion project is completed, a small hydropower station can be built near the Yuhe reservoir. As for the specific construction plan of the power station, it must wait until the strategic plan of diverting the stream into the power station is approved.

Divert the stream into the especially, benefit the people, and make a contribution to the future. This move can not only effectively solve the situation of insufficient water storage in the You River, but also alleviate the impact of the country's power shortage and drive the high-speed take-off of the industrial economy. It has broad development prospects and a bright future.

According to the relevant provisions of national laws, all holidays and anniversaries in the country are calculated by the solar calendar (Gregorian calendar). However, at present, especially in rural areas now, the commemorative dates of all relatives (generally referring to the birth and death of relatives) are mostly calculated by the lunar calendar (lunar calendar).

Due to the fact that the yin and yang dates are not fixed together, there are two commemorative dates in the year (yin and yang two commemorative dates). It seems unlikely that the yin and yang dates will be reunited together.

However, when I looked up the death date of the third anniversary of my mother's death on my mobile phone last year, I found a peculiar phenomenon:

I found that from October 5, 2013 (September 1 of the lunar calendar) to September 23, 2014 (August 30 of the lunar calendar), for nearly a year, the yin and yang dates were completely coincidental for nearly a year from October 5, 1975 (September 1 of the lunar calendar) to September 23, 1976 (August 30 of the lunar calendar).
