Anti-blocking sewer

Abstract

The invention relates to the field of municipal administration, and specifically relates to an anti-blocking sewer. The anti-blocking sewer comprises a concrete layer, a sewer inner wall, a manhole cover and a manhole cover flange, wherein hinges are symmetrically arranged inside the manhole cover, hinge rotation shafts are rotatably mounted in the hinges, cover plates are rotatably mounted on theouter rings of the hinge rotation shafts, cover plate side edges are fixedly mounted on the outer rings of the cover plates, handle rotation shafts are arranged on the middle part of the cover plates, handles are rotatably mounted on the two ends of rotation grooves, installation clamping blocks are arranged on the inner ring of the sewer inner wall, the installation clamping blocks are of a convex structure, a flange is arranged on the outer ring of the upper end of a material collection tank, and a material collection tank bottom plate is arranged at the bottom of the material collection tank. The entire material collection tank is taken out by using a hook to lift the handles after locating through a locating slot, internally-filtered impurities are cleared, a pipeline is effectively prevented from being blocked, the structure is stable and reliable, the operation is simple and efficient, and good practical value is realized.

However, due to the large amount of debris in the sewer, it is easy to block and has always been a world problem that has plagued all countries.

[0003] Chinese patent (notification number: CN 206916784 U, announcement date: 2018.01.23) discloses an anti-clogging sewer manhole cover. The body, the cover body and the anti-blocking layer are hollow inside. The cover body is provided with drain grids, anti-skid strips and openings. There is a stopper under the cover body. The anti-blocking layer includes anti-blocking strips and reinforcing ribs, and the anti-blocking strips are uniform. Distribution, the water tank is formed between each anti-blocking strip, the body is cylindrical, and there is a stop bar on the top. The problem is that the anti-clogging device does not collect impurities, which is easy to cause sediment accumulation
