River bridge water level monitoring alarm device

Abstract

The invention discloses a river area bridge water level monitoring and alarming device, belongs to the field of water level detection devices, and aims to provide a river area bridge water level monitoring and alarming device which has the advantages that in the daily river area water level monitoring process, an inspector can approximately know the water level depth through water level scale marks on a monitoring column, and the water level can be accurately monitored when the water level is at a low level. River water threatening is small, only daily inspection and maintenance need to be carried out, in the process that the water level of the river water rises suddenly, when the liquid level of the river water submerges the water inlet hole, the river water can enter the water inlet groove and the transition cavity through the water inlet hole and is gathered in the transition cavity, and the river water gathered in the transition cavity can promote the floating ball and the triggering device to float; when the trigger device pushes against the main contact switch, the alarm of the mobile terminal of the inspector is triggered, and in the process, the river water accumulated in the transition cavity is gradually discharged in one direction through the floating ball, so that the river water is not easy to accumulate in the transition cavity, and repeated use of the water leveldetection alarm device is not easy to influence.

Description

technical field [0001] The invention relates to the field of water level detection devices, in particular to a water level monitoring and alarming device for bridges in the river area. Background technique [0002] Rivers, oceans, lakes and other water bodies rise above a certain water level, threatening the safety of relevant areas, and even causing disasters. In areas with dense river systems, during the rainy season, a large amount of precipitation will cause the water level of the river to rise, seriously affecting the safety of the above-mentioned areas. Therefore, a corresponding water level detection system is usually established in the above-mentioned areas to detect the water level of the river, so as to carry out flood control and disaster relief activities in time. [0003] "Flooding and causing disasters" refers to the natural integration of the earth's ecology, resulting in regular concentrated precipitation on land (excluding winter snowfall), flood seasons, ra...

Problems solved by technology

[0004] Among them, most of the existing water level detection devices are detection devices that use the principle of river buoyancy. When the river water level is rising and fluctuating, the waves of the river water surface are more obvious. Mis-touching of the alarm device will cause unnecessary impact on the normal flood control and disaster relief work, and easily lead to the disorder of the entire flood control system. However, in the process of deep water, rapid flow, high wind and large waves, it is difficult to realize real-time dynamic monitoring of river water level, which is easy to normal adverse impact on flood control work
