Plugging preventing sewer cover plate

Abstract

The invention relates to a plugging preventing sewer cover plate which comprises a horizontally arranged cover plate body. The cover plate body is provided with multiple strip-shaped water draining holes, the bottom of the cover plate body is provided with a rotary shaft, the rotary shaft is rotatably connected with multiple dirt blocking rods, one end of each dirt blocking rod is fixedly connected through a connecting rod, the ends away from the connecting rods are upward overturned to extend out of the strip-shaped water draining holes when the multiple dirt blocking rods rotate on the rotary shaft, hanging chains are arranged on the connecting rods and are hung with water receiving boxes with the tops for water to be injected, and the bottoms of the water receiving boxes are provided with water draining ports. The plugging preventing sewer cover plate utilizes the gravity of rainwater, rainwater falls into the water receiving boxes when it rains, the gravity of each water receivingbox is increased to cause downward fall, the water receiving boxes downwards fall due to increased gravity and drive the ends, away from the connecting rods, of the dirt blocking rods to be upwards lifted, leaves, plastic bags, paper scraps, mudstones and the like on the strip-shaped water draining holes are jacked up, blockage of the strip-shaped water draining holes is avoided, and the pluggingpreventing sewer cover plate is low in cost and better in effect.

Description

technical field [0001] The invention relates to the technical field of urban drainage systems, in particular to an anti-clogging sewer cover. Background technique [0002] Every summer, due to heavy rainfall and other reasons, there will be waterlogging of many urban roads and squares, which will bring great economic losses to people. One of the reasons is that the sewage outlets of the urban sewage drainage pipe network system are washed out by the flood. Plastic bags, paper scraps, mudstones, etc. will block the sewage outlet, causing the drainage system to lose its function, thus causing roads, squares, etc. to be submerged. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-clogging sewer cover, which can automatically block leaves, plastic bags, paper scraps, mudstones, etc. in rainy weather, and avoid leaves, plastic bags, paper scraps, mudstones, etc. The strip-shaped drainage holes of the cover plat...
