Municipal drainage system

Abstract

The invention discloses a municipal drainage system and belongs to the technical field of municipal drainage. The municipal drainage system comprises a shell, wherein a water tank is formed in the middle of a top face of the shell, a guide rod is fixedly arranged at the position, opposite to an upper end of the front side of a movable plate, in a drainage channel, and drain outlets are formed in the positions, opposite to the movable plate, of the inner walls of the two sides of the drainage channel; collecting grooves are formed in the positions, opposite to the outer side end of the sewage draining outlet, of the two sides in the shell, a pressing plate is arranged on a top face of the outer side of a sealing plate, a pulling plate is fixedly arranged at a rear end of a top face of the pressing plate, and a bottom face of the sealing plate and bottom faces of the collecting grooves are each of a front-back symmetrical structure and provided with two round cavities; a compression spring is fixedly arranged between the interiors of the two circular cavities located on the same side. The energy of flowing water can be fully utilized, a phenomenon that impurities are accumulated on the front side of a roller to block water flow loss is avoided through back-and-forth movement of the movable plate, drainage efficiency of the drainage system is greatly improved, and water accumulation and waterlogging are avoided.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, more specifically, to a municipal drainage system. Background technique [0002] The municipal drainage system can also be called the urban drainage system. It refers to the engineering facility system for treating and removing urban sewage and rainwater. It is an integral part of urban public facilities. Urban drainage system planning is an important part of urban overall planning, usually by It is composed of drainage pipes and sewage treatment plants. In the case of sewage and rainwater separation system, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled. Rainwater runoff is collected by drainage pipes and discharged into nearby water bodies. , while the existing drainage pipe entrances are mostly rainwater inspection manhole covers for sealing and filtering, and the tanks provided on it to supply rainwater to leak int...

[0002] The municipal drainage system can also be called the urban drainage system. It refers to the engineering facility system for treating and removing urban sewage and rainwater. It is an integral part of urban public facilities. Urban drainage system planning is an important part of urban overall planning, usually by It is composed of drainage pipes and sewage treatment plants. In the case of sewage and rainwater separation system, sewage is collected by drainage pipes, sent to sewage treatment, and then discharged into water bodies or recycled. Rainwater runoff is collected by drainage pipes and discharged into nearby water bodies. , while the existing drainage pipe entrances are mostly rainwater inspection manhole covers for sealing and filtering, and the tanks provided on it to supply rainwater to leak into the pipes are mostly slender structures, which can block larger debris in the drainage In order to prevent pipeline blockage, but the existing manhole cover can not intercept small impurities, these impurities will cause blockage of the drainage system when they enter the drainage system with the water flow, and then cause the ground to produce water accumulation or even waterlogging, etc. At this time, the staff will choose to install a filter screen in the pipe of the drainage system or at the open end. Although this method can prevent impurities from entering the depth of the drainage system, the accumulation will still cause blockage, and the staff will have to Frequent sewage dredging is time-consuming, laborious and inefficient. In view of this, we propose a municipal drainage system
