Drainage manhole cover

Abstract

The invention discloses a drainage manhole cover. The technical scheme mainly includes that according to the drainage manhole cover, when a vehicle passes the manhole cover, a drive column positioned in the center of the manhole cover is driven to generate vertical displacement, a blockage clearing sleeve generates vertical displacement through a fixed connection rod, and a blockage clearing knife is arranged on the inner side of the blockage clearing sleeve and extends into the inner side of a drainage pipe through a blockage clearing groove in the drainage pipe to move vertically, so that debris in the drainage pipe can be pulverized; since the blockage clearing knife is arranged and can move in the drainage pipe conveniently, excellent pulverizing effects are achieved; a shaking mechanism enables the drainage pipe to swing horizontally, so that the debris can be pulverized more easily and blockage prevention is achieved. The drainage manhole cover solves the problem that an existing manhole cover drainage hole needs to be cleaned manually when being blocked and can achieve automatic cleaning, so that water can be drained more quickly in rainy seasons.

Description

technical field [0001] The 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 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 the...

[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
