Automatic drainage grate and method

Abstract

The invention provides an automatic drainage grate and method. The automatic drainage grate comprises a grate body, a grate base, a jacking mechanism and a control mechanism, wherein the grate body and the grate base are connected in a turnover manner through a grate hinge pin; the jacking mechanism is arranged on the other side, relative to the grate body, of the grate hinge pin, the control mechanism is electrically connected with the jacking mechanism, the jacking mechanism is used for controlling the grate body to bounce or fall at a certain angle according to the instruction of the control mechanism, the jacking mechanism further has compressibility, and the jacking mechanism is automatically pressed down and bounced according to external pressure; and the control mechanism comprisesa rainfall detection device, and the control mechanism automatically controls opening and closing of the jacking mechanism according to the rainwater water flow pressure transmitted through the rainfall detection device. The grate can be automatically controlled, time and labor are saved, and the risk of overall cover opening is reduced; and due to the fact that the grate body is fixed, the risk that the grate body is lost is reduced.

Description

technical field [0001] The invention relates to the technical field of urban road pavement drainage, in particular to an automatic drainage grate and a method. Background technique [0002] Drainage grate is a kind of drainage facility commonly used in municipal affairs. It has the function of intercepting and purging rainwater. The drainage capacity of drainage grate directly affects the drainage effect of road surface rainwater. The existing rainwater grate has poor drainage capacity due to the small area of ​​the drain outlet, and it is often unable to discharge the rainwater on the road surface in time in the face of heavy rain, which causes the road area to be too deep to affect the normal passage of pedestrians and vehicles. It can also cause personal injury or property damage. [0003] Invention patent CN109653339A discloses an automatic opening and closing rainwater grate, which can automatically control the opening and closing of the rainwater grate according to we...

AI Technical Summary

Problems solved by technology

This invention can alleviate the current situation of drainage pipeline silting, and the drainage effect is good, but the installation of the rainwater grate needs to cooperate with the road shoulder to block the drain outlet after the grate is opened, so it cannot be widely used on urban roads. In addition, the device has a complex structure and is difficult to maintain , high cost
