Problems solved by technology

Although the West-to-East Power Transmission can alleviate the power shortage in economically developed areas, due to the need to build ultra-high voltage and long-distance power transmission and transformation facilities, on the one hand, the investment cost is high and the line power loss during the power transmission and transformation process is large. On the other hand, it causes a serious waste of resources. On the other hand, the cost of line management and maintenance of the power supply department is high and a lot of manpower is invested.

Embodiment 1

[0022] See figure 1 , a dam 2 built on the upstream river 1 for intercepting and raising the water level of the upstream river 1 without affecting shipping is given (the function of the dam 2 is to raise the water level so that the collector pipe 4 can obtain water, but the shipping unaffected), a hydroelectric generator 3 installed downstream, and an energy concentration device for leading the water of the upstream river 1 intercepted by the dam 2 to the hydroelectric generator 3 so that the hydroelectric generator 3 generates electricity, wherein : the water outlet 31 of the water turbine generator 3 communicates with the downstream river 5 .

[0023] As the technical essentials of the technical solution provided by the present invention: the aforementioned energy concentration device is an energy collecting pipe 4, one end of the energy collecting pipe 4 is connected and communicated with the water inlet 21 of the dam 2, and the other end of the energy collecting pipe 4 is ...

Embodiment 2

[0031] See figure 2 A sand collection tank 311 is arranged at a position corresponding to the aforementioned water outlet 31 and the aforementioned downstream river 5, and the energy collecting pipe 4 is a prefabricated metal pipe. All the other are the same as the description to embodiment 1.

Embodiment 3

[0033] An exhaust pipe 41 is arranged on the energy collecting pipe 4 , and the upper end of the exhaust pipe 41 is higher than the level of the aforementioned upstream river 1 . In this embodiment, the energy collecting pipe 4 is an elbow with a wave crest and a wave trough, and the maximum height difference between the wave crest and the water inlet 21 is ≤8 meters. The energy collecting tube 4 of this structure can avoid obstacles such as buildings, etc. flexibly. All the other are the same as the description to embodiment 1.

Abstract

The invention provides a hydroelectric power station and belongs to the technical field of hydroelectric power facilities. The hydroelectric power station comprises a retaining dam, a hydraulic turbine generator and an energy concentration device, wherein the retaining dam is constructed on an upstream river and is used for intercepting and lifting the upstream river; the hydraulic turbine generator is mounted at the downstream; the energy concentration device is used for leading water of the upstream river, which is intercepted by the retaining dam, to the hydraulic turbine generator so that the hydraulic turbine generator generates power; a water outlet of the hydraulic turbine generator is communicated with the upstream river. The hydroelectric power station is characterized in that the energy concentration device is an energy collection pipe; one end of the energy collection pipe is connected and communicated with a water inlet of the retaining dam, and the other end of the energy collection pipe is connected with the hydraulic turbine generator. The hydroelectric power station has good landform adaptability and does not damage farmlands, mountain forests and villages and towns; the hydroelectric power station is suitable for natural river systems with great falls, is low in construction cost and can meet the requirements of nearby grid-connected generation; the investment and the resources can be saved; the energy collection pipe tends to be maintenance-free, and the good economical and cheap effects are reflected.

Description

technical field [0001] The invention belongs to the technical field of hydropower facilities, and in particular relates to a hydropower station. Background technique [0002] As we all know, the basic principle of hydroelectric power generation is to use the water level drop to cooperate with the hydroelectric generator to generate electricity, that is, to convert the potential energy of water into the mechanical energy of the hydraulic turbine, and then use the mechanical energy to drive the generator to obtain electricity. Known hydroelectric power generation is to build dams on rivers and lakes, block water to form huge reservoirs to increase water levels, store energy, and install hydroelectric generating units at the bottom of the dams (customarily called downstream). Usually, every time the water level increases by 10m, it can increase by 1kg / cm 2 water pressure. It can be seen that the larger the reservoir and the higher the embankment, that is, the higher the wate...
