Water level marking and warning device for municipal drainage

Abstract

The invention relates to the technical field of municipal drainage, and particularly relates to a water level marking and warning device for municipal drainage. The device comprises a fixing plate, supporting mechanisms, a placement mechanism, indicating mechanisms, a warning mechanism and a clamping mechanism. When the device is used, the supporting mechanisms are arranged on the periphery of thefixing plate, the whole device can be conveniently and stably fixed in a riverway through corresponding gear transmission structures and screw rod transmission structures, the fixing stability of thedevice is guaranteed, and the influence of torrent water flow is reduced; the indicating mechanisms are arranged inside and at the top of the placement mechanism, and play a corresponding role in indicating water level changes under the driving of buoyancy through corresponding gear and rack transmission structures, so that people can well perform early warning work when encountering floods; andthe warning mechanism is arranged in the placement mechanism, and through corresponding linkage assistance of the indicating mechanism, a corresponding warning effect is achieved when the water levelreaches a certain degree, so that people can obtain flood warning information conveniently.

Description

technical field [0001] The invention relates to the technical field of municipal drainage, in particular to a municipal drainage water level mark warning device. Background technique [0002] Municipal engineering refers to urban public utility projects such as urban roads, bridges, water supply and drainage, sewage treatment, urban flood control, gardens, road greening, street lights, and environmental sanitation. Among them, the municipal drainage project refers to the project of removing human domestic sewage, various waste water in production, and redundant surface water. It consists of drainage pipe system (or channel), wastewater treatment plant and final treatment facilities. Usually also includes pumping facilities (such as drainage pumping stations). Some large cities will also build artificial rivers in the middle of the city to ensure the smooth flow of municipal water supply and drainage projects. [0003] However, at present, once the artificial rivers used f...

AI Technical Summary

Problems solved by technology

[0003] However, at present, once the artificial rivers used for municipal drainage in many cities encounter continuous heavy rain or rainy weather, urban waterlogging is extremely prone to occur, and when the rainfall is particularly large, this kind of urban waterlogging will occur very quickly. The rising speed is very fast, which brings troubles to people's prevention work; sometimes, people will set some floating markers in the river, but these markers are vulnerable to the impact of turbulent water flow, and it is not convenient to fix them in the river
