In a water taking and conveying building, the trash rack is an indispensable device. The water inlets of pump stations, hydropower stations and ship lock water conveying galleries are generally provided with trash racks for blocking dirt such as aquatic weeds, floating trees and the like carried in water flow, so that the dirt is difficult to flow into a water diversion channel, units, gates, valves and pipelines are protected from being damaged, and the safe operation of the units and other equipment and structures is ensured. When the upstream incoming water contains too many impurities, the sewage is attached to the surface of the trash rack, so that the sewage passing capacity is insufficient, the pressure difference of the trash rack frequently exceeds the standard, and the sewage cleaning frequency is high. At present, the main trash cleaning mode of the trash rack is manual cleaning and configuration of a hydraulic grab bucket trash cleaning machine or a rotary trash cleaning machine, but for the condition that the amount of floating trash is large and the coming trash is concentrated in the flood season, other auxiliary trash cleaning measures need to be added for dealing with the situation. Common methods for removing the dirt include manual dirt removal and mechanical dirt removal. When the trash rack has the trash rack cleaning condition, the trash rack is lifted to the platform, and the trash is manually cleaned. The mechanical dirt cleaning is to use a dirt cleaner to drag dirt from the grid surface under the condition of moving water to clean the dirt. When the water surface is difficult to clean, a diver can also be used for cleaning the dirt before diving into the fence. However, these conventional methods are labor and material consuming and have high cost, so it is necessary to design a trash rack capable of automatically cleaning the trash.
