Description

Technical Field

[0001] The utility model relates to the technical field of dam maintenance components, in particular to a dam pollution cleaning and maintenance device for a hydropower station. Background Art

[0002] Hydroelectric power generation uses the kinetic energy of strong water flow generated by water level difference to generate electricity. A power station that uses hydroelectric power is called a hydroelectric power station, or hydropower station for short. The water level difference of some hydropower stations is achieved through dams. When the dam is discharged and eroded for a long time, its dam surface is prone to damage such as pits and cracks, which requires maintenance personnel to inspect and maintain it. When the existing maintenance device is used, most of them use multiple sets of support frames to build a large-area support platform, which increases the cycle and also creates construction risks, and has limited practicality. For this reason, we propose a hydropower station dam cleaning and maintenance device. Utility Model Content
