The water collecting frame 2 is arranged above the installation frame 1, and the dredging cover 3 is arranged above the water collecting frame 2. There are gaps between the outer side and the bottom of the dredging cover 3 and the water collecting frame 2, and wastewater flows downward from the gap into the interior of the water collecting frame 2. A sealing frame 4 is arranged below the installation frame 1. The dredging cover 3 comprises a cover body 31, an insertion column 32, a lifting column 33, a lifting frame 34, a limiting horizontal plate 35 and a reset spring 36. The cover An inserting column 32 is fixedly connected to the bottom end of the cover 31, and a lifting column 33 is fixedly connected to the central area of ​​the bottom of the cover 31. The lifting columns 33 are distributed in an array on the cover 31, and the bottom ends of the lifting columns 33 are inserted in the lifting frame 34. A limiting horizontal plate 35 is provided inside the lifting frame 34. The limiting horizontal plate 35 is fixedly connected to the lifting frame 34. A return spring 36 is wound around the outside of the lifting column 33. The lifting column 33 is located inside and outside the lifting frame 34 and is provided with limiting end plates to limit the movable distance of the lifting column 33.

[0019] Furthermore, the sealing frame 4 includes an internal frame body 41 and a side flow hole 42. The top of the internal frame body 41 is fixedly connected to the mounting frame 1. The bottom of the internal frame body 41 is provided with a side flow hole 42. Wastewater entering the internal frame body 41 from the gap can be discharged from the side flow hole 42.

[0020] Furthermore, the water collecting frame 2 includes an external frame 21, a drainage hole 22 and an insertion hole 23. The gap left between the external frame 21 and the cover 31 is only for the wastewater and the small impurities it carries to flow, while the remaining larger debris is blocked outside the cover 31, thereby achieving a coarse filtration effect. The external frame 21 is provided with a drainage hole 22, which is distributed in an array on the external frame 21. An insertion hole 23 is provided in the central area of ​​the external frame 21. Three insertion holes 23 are provided and distributed in an array, and a lifting column 33 is inserted inside the insertion hole 23.
