Water discharging manhole cover capable of automatically hoisting

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 in particular relates to an automatic lifting drainage manhole cover. Background technique [0002] With the development of modern society, the role of urban underground drainage pipes has become more and more important. It is well known that the extensive use of cement concrete reduces the pavement's ability to absorb rainwater, thereby increasing the drainage pressure of underground drainage pipes. Existing drainage pipes are laid in the foundation under the pavement in the shape of a net, and the wellheads of the drainage wells connected with the drainage pipes are located on the road surface, and the wellheads of the drainage wells are covered on the wellheads of the drainage wells. The commonly used drainage manhole cover usually adopts an integral structure at present, and there is no connection between the drainage manhole cover and the drainage well, a...

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
