Problems solved by technology
The prerequisite for traditional hydroelectric power generation is the water level drop. However, in mountainous areas with water resources, there are relatively few natural conditions for building high water level reservoirs to generate electricity, and the investment is large and the construction period is long.
High water head hydropower stations are used to generate electricity, and the number of repeated use of water resources is limited, resulting in low utilization of water resources

The invention provides a hydroelectric generation device used for a retaining dam. The hydroelectric generation device comprises a spindle, a water wheel, an eccentric mechanism, a hydraulic oil tank, a hydraulic cylinder, a hydraulic motor and an electric generator. The two ends of the spindle are mounted in bearing seats on supporting columns through bearings. The water wheel is provided with a rotating wheel and multiple water buckets. The eccentric mechanism comprises a disc, an eccentric shaft and a sliding sleeve. The hydraulic oil tank contains hydraulic oil. A rod cavity of the hydraulic cylinder is provided with a first oil inlet and a first oil outlet, and a rodless cavity of the hydraulic cylinder is provided with a second oil inlet and a second oil outlet. The first oil inlet and the second oil inlet are connected with the hydraulic oil tank through oil inlet pipelines, and the oil inlet pipelines are provided with oil inlet one-way valves capable of preventing oil from backwards flowing into the hydraulic oil tank. The first oil outlet and the second oil outlet are connected with an oil inlet of the hydraulic motor through oil outlet pipelines. The electric generator is driven by the hydraulic motor to rotate. Through the hydroelectric generation device, low-water-level power generation can be conveniently achieved.
Description
technical field [0001] The invention relates to the field of hydroelectric power generation, and in particular, the invention relates to a hydroelectric power generation device used for water retaining dams, which can be applied to generate electricity in a low water level environment. Background technique [0002] Hydropower is a renewable energy, an inexhaustible clean and sustainable energy. At present, driven by the strong demand for electricity, my country is increasing its efforts in the development of hydropower, and taking hydropower as the main measure of energy substitution and emission reduction as the first choice. [0003] my country's hydropower resources are mainly distributed in the western region, accounting for more than three-quarters of the country, but the current development rate is only 8%. There are many industries in the central and eastern parts of my country, and there is a large demand for electricity. West-to-east power transmission is the main ...
