Technical Field

[0001] The utility model relates to the technical field of hydropower generation, in particular to a hydropower generation device. Background Art

[0002] Hydroelectric power generation uses water with potential energy from high places such as rivers and lakes to flow to lower places, converting the potential energy contained therein into kinetic energy of hydraulic machinery, using water force to drive the hydraulic machinery to rotate, converting water energy into mechanical energy, and using hydraulic machinery as the motive force to drive the generator to generate electricity. The actual process of hydroelectric power generation is the process of converting the potential energy of water into mechanical energy and then into electrical energy. Hydroelectric power generation is a renewable energy source and has less impact on the environment.
