Description

Adjustable flood prevention alarm device capable of giving stable alarm

Technical Field

The utility model relates to the field of hydraulic engineering, in particular to an adjustable flood prevention alarm device capable of stably alarming.

Background

The hydraulic engineering is used for controlling and allocating groundwater on the surface of the natural world to achieve the aim of removing harm and benefiting, the influence of water level is most direct in general, the height of the water level determines how to design different hydraulic engineering buildings, and the hydraulic engineering can also early warn disasters to play a role in flood prevention and alarm, so that the water level monitoring is an indispensable important link in the hydraulic engineering monitoring work. The water level monitoring work mainly monitors the water depth of water bodies at the positions of dams, ditches, riverways and the like, at present, the water level monitoring mostly adopts a method of setting a marker post or marking a water level warning line on the inclined wall of a dam body to warn the current water level, and the two modes are simple in structure and easy to realize, but when the water level of the water body reaches the warning water level, warning prompts can not be automatically sent to staff, the staff is required to check the water level at regular time, the workload of the staff is greatly increased, rapid response can not be achieved for water level flood prevention warning, timely prevention and control are realized, a certain potential safety hazard exists, and the current flood prevention requirement can not be met;

in patent number CN202221408250.5, a hydraulic engineering flood prevention alarm device is disclosed, when a floating block floats to the same height as an alarm assembly and an adjusting power assembly due to buoyancy, the alarm assembly is connected and conducted with the adjusting power assembly, and the alarm assembly gives an alarm.
