Description

Urban waterlogging prevention inspection well cover

Technical Field

The invention relates to the technical field of inspection well covers, in particular to an urban waterlogging prevention inspection well cover.

Background

There are many underground pipes in urban construction, such as sewers, underground gas pipes, water supply pipes, power pipes, communication pipes, defense pipes, etc., which have an outlet to the ground at every other section, the section from the pipe to the ground is called a manhole, which is usually flush with the ground, and therefore a cover is needed to cover the manhole, called a manhole cover.

The inspection well cover is generally laid at a sewer outlet, most of the inspection well covers are not locked for the later-stage convenient replacement and opening of drainage work, however, every time in a rainstorm season, old urban drainage systems of some cities are too old, rainwater in the sewer is caused to flow outwards when the rainfall is too large, strong water pressure sometimes even flushes the inspection well cover, pedestrians or vehicles can sink into the sewer without being conscious of the pedestrians or vehicles when the pedestrians or vehicles walk, and the inspection well cover has great potential safety hazards.

Disclosure of Invention

The invention aims to overcome the defects that rainwater of a sewer is poured outside and a strong water pressure sometimes even flushes an inspection well cover to cause pedestrians or vehicles to sink into the sewer without worrying about when the pedestrians or vehicles walk and have great potential safety hazards in the prior art, and accordingly the urban waterlogging prevention inspection well cover is provided.

In order to achieve the purpose, the invention adopts the following technical scheme:

an urban waterlogging prevention inspection well cover, which comprises: the water leakage prevention device comprises a prefabricated steel casting fixed on the ground, wherein an outer cover body is placed in the prefabricated steel casting, a water storage tank is arranged at the center of the outer cover body, a plurality of water leakage holes are formed in the bottom wall of the water storage tank, a diversion trench is formed in the outer cover body, clamping mechanisms are symmetrically arranged in the diversion trench and comprise a piston block, a clamping rod is fixedly connected to one side of the piston block, a spring is sleeved on the clamping rod, one end of the spring is fixedly connected to the piston block, the other end of the spring is fixedly connected to the side wall of the diversion trench, and a clamping groove matched with the clamping rod is formed in the prefabricated steel casting;

the bottom side of the inner cover body is symmetrically and fixedly connected with a floating plate, a communicating pipe is fixedly inserted in the inner cover body, the bottom side of the outer cover body is symmetrically and fixedly connected with a guide sleeve, the guide groove is communicated with the guide sleeve, a sealing sliding block is slidably connected in the guide sleeve, the communicating pipe is fixedly arranged by penetrating through the sealing sliding block, the inner cover body is symmetrically and fixedly connected with a shutoff plate, and the upper end of the shutoff plate extends into the guide groove and is fixedly connected with a sealing gasket.

Preferably, the side wall of the bottom of the diversion trench is symmetrically provided with drain holes, and the drain holes are positioned right below the water storage trench.

Preferably, the bottom side of the outer cover body is fixedly connected with a sealing block, and the sealing block is symmetrically provided with flow guide inclined planes.

Preferably, drainage pipes are symmetrically pre-buried in the bottom sides of the prefabricated steel castings.

Compared with the prior art, the invention has the beneficial effects that:

1. when the rainfall is great, the sewer can't satisfy the drainage demand, rainwater begins to irritate outward in the sewer, along with the rising of water level, the lid begins to rise in driving under the buoyancy of kickboard, closely laminate with the sealed piece and realize primary seal until interior lid, the upside of closure plate tightly supports the last lateral wall that the guiding gutter realizes secondary seal simultaneously, the rainwater pours into the guiding gutter backward through communicating pipe in, thereby push the piston piece and slide under hydraulic effect, go into the draw-in groove until the kelly card, make the outer lid get into locking state, both sides drainage pipe is opened and is assisted the drainage, effectively avoided the outer lid to be washed away by the rainwater, people's life and property safety has been protected.

2. When rainfall is less, the water level descends in the sewer, drives the kelly and resets under spring force effect, accumulates ground ponding through the catch basin this moment, flows into the guiding gutter through the hole that leaks in, then discharges from the wash port, satisfies the drainage demand of surface ponding behind the rain to the enclosing cover is in the unblock state under daily use, and the staff can take out the enclosing cover at any time and change and the drainage.
