Description

Technical Field

[0001] The utility model relates to the technical field of pollution cleaning of hydropower stations, in particular to a pollution cleaning device for a water inlet of a water diversion type hydropower station. Background Art

[0002] In the construction of a diversion type hydropower station, the hydropower station introduces the dam water into the plant turbine unit through a diversion tunnel to drive the water wheel, and then the water wheel drives the unit rotor to rotate. During the rotation of the rotor, the magnetic flux lines of the stator coil are cut to generate electricity to generate electricity. Therefore, during the diversion and power generation process of the hydropower station, foreign matter is not allowed to enter the dam water inlet. Hydropower stations generally use trash racks to intercept trash. When the trash rack assembly is used for long-term filtering, excessive foreign matter will accumulate on the surface of the trash rack assembly, which will affect the subsequent water inlet and discharge effect. For this reason, we propose a trash cleaning device for the water inlet of a diversion type hydropower station. Utility Model Content
