s4, the friction disc (9) drives the reel (11) to rotate, the steel wire rope (12) is wound, the dirt cleaning frame (13) is pulled out of the water surface, and the dirt cleaning frame (13) is cleaned;
s5, after the cleaning frame (13) cleans the accumulated large garbage, the water surface flow is accelerated, so that the baffle (76) is far away from the sleeve (71), the power is cut off, the hydraulic supply is stopped, the friction plate (18) is not contacted with the friction disc (9), and the daily cleaning operation can be continued.
