A manhole cover 5 is horizontally arranged above the interior of the drainage well 1, and several groups of water inlets are opened on the manhole cover 5. Four positioning mechanisms 2 are arranged around the manhole cover 5. A drainage port 6 is opened at the bottom of the drainage well 1, and two rod bodies 15 are fixedly installed at the bottom of the inner side of the drainage well 1. The rod bodies 15 are fixedly installed with limit blocks. The rod bodies 15 vertically penetrate the floating plate 7. The floating plate 7 has a through hole for the rod bodies 15 to pass through. The floating plate 7 is slidably connected to the rod bodies 15. A filter screen plate 8 is arranged above the floating plate 7 in the drainage well 1, and the filter screen plate 8 is placed on the top of the positioning ring 9. The positioning ring 9 is fixedly installed on the inner side of the drainage well 1, and the floating plate 7 is made of buoyancy material.
