a drainage manhole cover

Abstract

The invention discloses a drainage manhole cover. The main point of the technical solution is that when a vehicle passes the manhole cover, it drives the driving column located in the center of the manhole cover, and the driving column produces an up and down displacement. At this time, by fixing the connecting rod, the blockage clearing casing simultaneously produces an up and down movement. Displacement, because the inner side of the unclogging sleeve is provided with a unclogging knife, the unclogging knife extends into the inner side of the drainpipe through the unclogging groove on the drainpipe and moves up and down, so that the sundries in the drainpipe can be crushed; through The structure of the unclogging knife is set so that it can be easily moved in the drain pipe, and at the same time it has a good crushing effect. Further, the shaking mechanism enables the drain pipe to swing horizontally so that the sundries can be crushed more easily to achieve the purpose of preventing blockage. The invention solves the problem that the drain hole of the existing manhole cover is blocked and requires manual cleaning, realizes automatic cleaning, and is beneficial to drain water faster in the rainy season.

Description

technical field [0001] The present invention relates to municipal engineering equipment, more specifically, it relates to a drainage well cover. Background technique [0002] Manhole covers, especially those in municipal engineering, generally appear on roads or parks and other places to cover the well body to prevent people or objects from falling. However, the manhole covers on the well bodies of some sewers will be provided with corresponding drainage holes, which can play a certain role in drainage when the rainy season comes. [0003] However, during normal use, the drainage holes on the manhole cover will often be blocked. If the drainage holes of the manhole cover are blocked, when the rainy season comes, it will not be able to drain in time, or it needs to be cleaned manually to be able to drain normally. , will undoubtedly have an adverse effect on the rate of drainage. [0004] In order to solve the above problems, it is very necessary to design a manhole cover t...

Problems solved by technology

[0003] However, during normal use, the drain hole on the manhole cover will often be blocked. If the drain hole of the manhole cover is blocked, when the rainy season comes, it cannot be drained in time, or it needs to be manually cleaned to drain normally. , will undoubtedly have an adverse effect on the drainage speed

[0004] In order to solve the above problems, it is very necessary to design a manhole cover that can automatically clean the drain holes in time, which can greatly reduce the phenomenon that the drain holes on the manhole cover are blocked
