An anti-blocking and anti-odor drainage well cover

Abstract

The invention discloses an anti-blocking and odor-resisting drainage well lid and belongs to the field of well lids. The anti-blocking and odor-resisting drainage well lid comprises a well lid body, two first drainage holes and two second drainage holes, wherein a drainage channel which penetrates through the whole well lid body in a manner of extending downward from the inner parts of the seconddrainage holes; a floating rod stretches into the second drainage holes from the upper sides of the second drainage holes and extends downward to penetrate through the whole drainage channel and thenstretch into a supporting seat; a floating cover is connected with the upper end of the floating rod; a positioning barrel is arranged in a manner of upward extending from the upper surface of the supporting seat; a spiral shaft pipe sleeves the outer side of the positioning barrel; spiral blades are fixed on the outer surface of the spiral shaft pipe; the lower part of the spiral shaft pipe is connected with a rotary wheel on an output shaft of a motor through a transmission belt. Aims at overcoming the disadvantages that an existing well lid can be used for effectively preventing blocking and resisting odor, the invention provides the anti-blocking and odor-resisting drainage well lid; the anti-blocking and odor-resisting drainage well lid realizes anti-blocking and odor-resisting functions of the well lid at the same time.

Description

technical field [0001] The invention relates to a well cover, in particular to an anti-blocking and anti-odor 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 is often 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 the prior art, there have been relevant patent disclosures about manhole covers with anti-blocking functions, such as pate...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to overcome the deficiency that the existing manhole cover cannot effectively prevent blockage and deodorize, and provide an anti-blockage and deodorization drainage manhole cover, which can realize the anti-blockage and deodorization functions of the manhole cover at the same time
