Anti-fall manhole cover for municipal engineering

Abstract

The invention discloses an anti-falling manhole cover for municipal engineering. The anti-falling manhole cover comprises a base, an inner ring of the base is equidistantly provided with clamping slots, anti-falling sleeves are clamped and connected into the clamping slots, a manhole cover opening is formed in the position, at the upper ends of the clamping slots, on the base, a manhole cover bodyis clamped into the manhole cover opening, water inlets are formed in the manhole cover body, fixed lugs are symmetrically connected to the outer wall of the manhole cover body, and the fixed lugs are connected with the base through bayonet locks; and clamping rings are fixedly connected to the upper ends of the anti-falling sleeves. By means of the anti-falling manhole cover for municipal engineering, the manhole cover body has the effect of protecting pavements, water is conveniently drained away, the double anti-falling function can be achieved when the manhole cover body is damaged, the anti-falling effect is good, and the safety performance is improved; and additionally, an anti-falling bottom plate is provided with an accumulated water outlet, movable connection with a movable rod is achieved to be used for discharging water inside a sewer under extreme weather, and the condition that water pressure inside the sewer is too large, the manhole cover is washed away, and safety hazards are caused is prevented.

Description

technical field [0001] The invention relates to the technical field of municipal well covers, in particular to an anti-falling well cover for municipal engineering. Background technique [0002] At present, manhole covers are generally covered on inspection wells, and manhole covers are easy to be stolen and damaged. Pedestrians often fall into manhole covers without manhole covers. In order to solve the above problems, there are anti-drop nets on the market, which are fixed on the well wall of the inspection well. When pedestrians fall, the anti-drop net will play a protective role, but the anti-drop net is made of nylon, which is easy to age, and it will be exposed to sewage for a long time. Immersion is easy to corrode, the bearing capacity is insufficient, and there is still danger. In addition, the existing manhole cover does not have the function of deodorization, and the odor inside the sewer is easily dispersed to the top, polluting the environment. SUMMARY OF THE...

AI Technical Summary

Problems solved by technology

[0002] At present, the manhole cover is generally covered on the inspection well, and the manhole cover is easy to be stolen and damaged, and the accidents of pedestrians falling often occur in the inspection wells that have lost the manhole cover.

In order to solve the above problems, anti-fall nets have appeared on the market, which are fixed on the well wall of the inspection well. When pedestrians fall, the anti-fall nets will play a protective role. However, the anti-fall nets are made of nylon, which is easy to age. Soaking is easy to corrode, insufficient bearing capacity, still dangerous

And the existing manhole cover does not have anti-odor function, the smell inside the sewer is easy to float to the top, polluting the environment
