Rotating type self opening and closing inspection well lid

Abstract

The invention relates to a rotating type self opening and closing inspection well lid, which comprises a casing, an outer cover, a rotating body and an inner lid, wherein the outer cover is arranged on the top of the casing, the rotating body is arranged in an inner cavity of the casing, the inner lid is arranged on the top of the rotating body, a guide rail is arranged on the rotating body, and a slide block is driven to move on the guide rail through the buoyancy of water, so the rotating body is driven to rotate, a water discharge opening of the inner lid is matched with the position of a water discharge opening of an outer lid, and the goal of opening the inspection well lid is achieved. The rotating body moves to drive the inner lid to rotate through the buoyancy of the water, other energy does not need to be consumed, and the environment-friendly effect is good. The outer lid does not need to be opened, after the water discharge quantity is increased, the inspection well lid does not need to leave the original position, and safety risk cannot be caused on pedestrians. The outer lid is connected with the casing, cannot be easily disconnected from the casing and cannot be easily stolen, so the stealing risk of the inspection well lid is greatly reduced.

Description

technical field [0001] The invention relates to the field of sewer drainage, in particular to a rotary self-opening inspection well cover. Background technique [0002] In recent years, the safety problem of manhole covers has become increasingly prominent and the situation is grim, and it has gradually become a social problem that attracts people's attention. It is not uncommon to see such news that manhole covers are stolen or manhole covers are dislodged, causing pedestrians to fall accidentally. Today's inspection manhole cover plays "multiple roles". It is not only a necessary equipment for urban drainage, but also a cash cow in the eyes of criminals. What is more worrying is that its design flaws have become a trap for the city. [0003] Most of the existing manhole covers need to be opened manually, and the daily drainage is low, so it is difficult to discharge the flood in time when a flood disaster occurs. Simultaneously, after opening the manhole cover, the mouth...

AI Technical Summary

Problems solved by technology

[0005] Purpose of the invention: In order to solve the problems in the prior art that the inspection shaft cover cannot drain water in time when the drainage volume is large, and it is easy to hinder the safety of pedestrians and be stolen when it is opened, the present invention provides a rotary self-opening inspection shaft cover, which controls the rotation of the inner cover through buoyancy , so that the leakage hole on the inner cover fits with the outer cover, and the outer cover can achieve the purpose of a large amount of drainage without manual opening, which solves the problems of the prior art
