Drainage manhole cover

Abstract

The invention discloses a drainage manhole cover. The technical scheme of the drainage manhole cover is characterized in that when a vehicle passes by the manhole cover, a driving post at the center of the manhole cover is driven to move vertically; at the time, a blockage clearing sleeve pipe move vertically at the same time through a fixed connection rod; a blockage clearing knife is arranged on the inner side of the blockage clearing sleeve pipe, and the blockage clearing knife extends into the inner side of a drainage pipe to move vertically through a blockage clearing groove in the drainage pipe, so that junk in the drainage pipe can be crushed; the structure of the blockage clearing knife is arranged, so that the blockage clearing knife can conveniently move in the drainage pipe, and meanwhile, a good crushing effect is provided; and furthermore, a swinging mechanism is arranged, and thus the drainage pipe can horizontally swing, so that the junk can be crushed more easily, and the aim of anti-blocking is reached. By adopting the drainage manhole cover, the problem of a current manhole cover that a drainage hole is blocked and needs to be cleared manually is solved; automatic clearing is realized; and water can be drained more rapidly in a rainy season.

Description

technical field [0001] The invention relates to municipal engineering equipment, more specifically, it relates to a well cover for drainage. Background technique [0002] Manhole covers, especially those in municipal engineering, generally appear in places such as roads or parks, and are used to cover wells to prevent people or objects from falling. Yet the well cover on the well body of some sewers can be provided with corresponding drainage holes, and these drainage holes can play a certain drainage effect when the rainy season comes. [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 well cover that can automatically clean...

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
