Abstract
The invention provides a movable manhole cover which comprises a manhole cover body provided with a through hole and further comprises a manhole cover lower base. The manhole cover body and the manhole cover lower base are connected through an air bag which is provided with an air leakage hole, and an air inflation hole of the air bag is communicated with the through hole. Compared with the prior art, the movable manhole cover can pop up automatically to recover the original appearance during collapse and is simple in theory and convenient to install.
Description
Technical field
The present invention relates to basis instrument field, city, particularly a kind of movable well lid.
Background technology
At present, urban Underground pipeline is more and more, and correspondingly, various well lids also play an important role.A variety of, individual layer, double-deck, cast iron, ductile iron, compound, cement, magnesite etc. are arranged in the national standard of China's well lid.Yet all there is a problem in these well lids, are difficult to automatically reply original appearance afterwards in case subside exactly, present a hole, have brought certain potential safety hazard for pedestrian and vehicle.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of movable well lid, can when subsiding, recover original appearance by automatic spring, have characteristics easy to use simple in structure.
To achieve these goals, the technical solution used in the present invention is:
A kind of movable well lid comprises well lid body 1, and through hole 3 is arranged on the well lid body 1, also comprises lower 6 of well lid, links to each other by air bag 2 between lower 6 of well lid body 1 and the well lid, and bleeder port 4 is arranged on the air bag 2, and the air-filled pore 5 of air bag 2 is communicated with through hole 3.
The present invention compared with prior art can recover original appearance by automatic spring when subsiding, its principle is simple, and is easy for installation.
Description of drawings
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is carried out more detailed explanation.
As shown in the figure, the present invention is a kind of movable well lid, comprises well lid body 1, through hole 3 is arranged on the well lid body 1, also comprise lower 6 of well lid, link to each other by air bag 2 between lower 6 of well lid body 1 and the well lid, bleeder port 4 is arranged on the air bag 2, and the air-filled pore 5 of air bag 2 is communicated with through hole 3.
In case the situation that occurs subsiding, then air bag 2 work, under the effect of elastic force, slowly recover original appearance, recover if be not enough to, then inflate to air-filled pore 5 by through hole 3, so that the elastic force of air bag 2 is larger, if do not need these, then by bleeder port the gas of air bag 2 inside is emitted, become common well lid.Air bag 2 can be selected high performance device, to ensure elastic effect.
The present invention compared with prior art can recover original appearance by automatic spring when subsiding, its principle is simple, and is easy for installation.
