S4, the friction disc (9) drives the reel (11) to rotate, the steel wire rope (12) is wound, the trash cleaning frame (13) is pulled out of the water surface, and the trash cleaning frame (13) is cleaned;
S5, after the accumulated large garbage is cleaned by the garbage cleaning frame (13), the water surface flow is quickened, so that the baffle plate (76) is far away from the sleeve (71), power is cut off, hydraulic supply is stopped, the friction plate (18) is not contacted with the friction plate (9) any more, and daily garbage cleaning operation can be continued.
