Mosquito breeding preventing cover plate for inspection well

Abstract

The invention discloses a mosquito breeding preventing cover plate for an inspection well. The mosquito breeding preventing cover plate is provided with a spherical part, a side elevation part and an edge part; the spherical part is arranged in the middle area of the cover plate, anti-mosquito water leak holes are uniformly distributed on the spherical part, and each anti-mosquito water leak hole is smaller than the passing requirement of a mosquito; an upper port of each anti-mosquito water leak hole is small, a lower port of each anti-mosquito water leak hole is big, and the upper port is provided with an annular cutting edge part extending towards the central axis; the side elevation part is arranged between the outer edge of the spherical part and the inner edge of the edge part, a plurality of anti-mosquito water leak long holes are vertically formed on the side elevation part, and each anti-mosquito water leak long hole is smaller than the passing requirement of the mosquito; the width of an outer port of each anti-mosquito water leak long hole is smaller than that of an inner port, and the outer port is provided with a cutting edge part; the upper surface of the edge part is inclined towards the anti-mosquito water leak long hole to form a water flow slope. By adopting the mosquito breeding preventing cover plate, not only can the mosquito be prevented from entering the inspection well, but also flexibility in water leakage can be realized, and the clogging is avoided.

Description

technical field [0001] The invention relates to an anti-mosquito breeding cover plate for inspection wells, which can be applied to inspection wells of all sewers and facilities with similar functions. Background technique [0002] At present, the manhole covers of many sewers are not mosquito-proof, so many manholes have become excellent breeding grounds and daily storage rooms for mosquitoes. In order to solve the problem that manhole covers cannot prevent mosquitoes, those skilled in the art have also designed various anti-mosquito structures that can be applied to manhole covers. For example: an anti-mosquito gate (patent No. 200720055856.4) belongs to the field of sewers and sewage wells. The utility model is a product placed under a manhole cover or a water grate. It consists of a funnel and a movable baffle. A movable baffle is set, and the movable baffle is connected to the funnel by a pin, and the movable baffle can rotate around the pin, and the movable baffle is ...

AI Technical Summary

Problems solved by technology

[0005] Although the above-mentioned patents can be applied to the anti-mosquito of the manhole cover, because these products all adopt the valve structure, after a long time, dust, garbage, etc. are easy to accumulate in the valve body, which easily leads to the formation of small mosquito breeding sites in the valve. environment, it is also easy to make the valve body rust, etc., resulting in difficulty in opening and closing or failure

Therefore, it is not widely used
