Connecting blocks 403 of matching sizes are provided on the upper and lower outer walls of the rotating shaft 402, and rotating plates 404 are connected and installed on both sides of the outer wall of the connecting block 403. Turn on the power of the driving motor 401 to drive the connecting block 403 installed on the outer wall of the rotating shaft 402 to move, so that the rotating plate 404 can stir the water flow, and at the same time, a plurality of barbs are provided on the surface of the rotating plate 404, which can speed up the subdivision of impurities inside the filtering device, thereby filtering from the filter screen 5 on one side;

[0023] The filter screen 5 is connected and installed on one side of the inner wall of the filter pipe 1. The inner wall of the filter pipe 1 is welded with a shielding mechanism 6 on both sides. The shielding mechanism 6 includes an inclined panel 601 and a hole 602. The inclined panels 601 are welded and installed on both sides of the inner wall of the filter pipe 1. The inner wall of the inclined panel 601 is provided with a hole 602. The filter pipe 1 is connected and installed at a position where drainage is required. When the water flows, large particles of impurities can be blocked in the holes 602 provided on the inner wall of the inclined panel 601, so as to fall into the lower connecting groove 7. The inclined panel 601 is an inclined trapezoidal structure, and the inclined panels 601 are evenly spaced on the filter pipe 1, so that large particles of impurities can be evenly filtered and can fall into the lower connecting groove 7 along the inclined panel 601 for collection.
