An automatic lifting drainage manhole cover

Abstract

The invention provides a water discharging manhole cover capable of automatically hoisting. The water discharging manhole cover comprises a manhole cover, a manhole cover base, two spring hinging mechanisms, a manhole cover floating cabin, a rainwater collector and an alarming device, wherein the manhole cover base is fixedly arranged on a well opening of a water discharging well; the manhole cover is placed on the manhole cover base; the two spring hinging mechanisms are connected between the manhole cover and the manhole cover base; the rainwater collector is located below the manhole cover floating cabin; and the alarming device is arranged in a central hole of the manhole cover and a manhole cover floating cabin through hole in a penetrating manner. The manhole cover of the water discharging manhole cover is made of a high-strength and light-mass material and can be automatically opened and closed by the manhole cover floating cabin according to the water depositing amount above the manhole cover, namely the water discharging manhole cover has a function of automatically and vertically hoisting, so that the discharging capability of water deposited at a road surface is enhanced. Furthermore, the manhole cover is connected with the manhole cover base through the spring hinging mechanisms so that the manhole cover is prevented from being washed away by the water; and the alarming device is used for providing alarms to pedestrians and vehicles so that the safety is good. Furthermore, the water discharging manhole cover also has the advantages of reasonable and simple structural design, complete functions, convenience for maintenance and the like.

Description

Technical field [0001] The invention belongs to the technical field of general (public) construction equipment, and particularly relates to a drainage well cover that can be automatically raised and lowered. Background technique [0002] With the development of modern society, the role of urban underground drainage pipes has become more and more important. As we all know, the extensive use of cement concrete reduces the absorption capacity of the road surface for rainwater, thereby increasing the drainage pressure of underground drainage pipes. Existing drainage pipes are laid in a net shape in the foundation under the road surface. The wellhead of the drainage well connected with the drainage pipe is located on the road surface, and the drainage well cover covers the wellhead of the drainage well. Currently commonly used drainage manhole covers usually adopt an integrated structure, and there is no connection between the drainage manhole cover and the drainage well, and the pos...

AI Technical Summary

Problems solved by technology

At present, the commonly used drainage manhole cover usually adopts an integrated structure, and there is no connection between the drainage manhole cover and the drainage well, and the positions of the two are relatively fixed. In addition, it is laborious to move the drainage manhole cover, and it is rarely opened

Although the drainage manhole cover of this structure can drain water, cover the drainage well and protect pedestrians and vehicles on the road when the rainfall is small, if the rainfall exceeds the full capacity of the drainage pipe, there will be a lot of water on the road. In this case, the drainage manhole cover of this one-piece structure will expose some problems: the water pressure of the drainage pipe may lift the manhole cover and be washed away by rainwater, and at this time, there is no warning sign at the drainage well, so that The drainage well becomes a trap for pedestrians and vehicles, so the safety is poor; in addition, because the rainwater cannot be discharged in time, and there is a large amount of water around the drainage well, and this integrated drainage well cover cannot be opened automatically, so it does not have auxiliary drainage. effect
