The first motor 306 can be started regularly. When the first motor 306 rotates, the screw shaft 305 rotates to drive the scraper 303 to clean the surface of the filter screen 203, preventing the filter screen from being blocked. When it is necessary to clean the waterweeds and other debris intercepted inside the interception cover 201, control the front ends of multiple hydraulic devices 4 to extend forward. During the extension process, drive the interception cover 201 to lift upward with the hinge frame 205 as the fulcrum. At the same time, start the second motor 503. After the waterweeds and other debris inside the interception cover 201 fall into the inner cavity of the conveying trough 501, the screw conveying shaft 502 arranged inside the conveying trough 501 conveys these waterweeds and debris to the end of the conveying trough 501 where the silt discharge pipe 504 is provided, and then discharges them through the silt discharge pipe 504.
