Monitoring system and monitoring device of riverbed structure

Abstract

The invention relates to a monitoring system of a riverbed structure. The monitoring system is used for monitoring structural change of an underwater riverbed and outputting a sensing signal corresponding to the structural change of the riverbed. The monitoring system comprises an H-shaped support unit and at least one monitoring unit, wherein, at least part of the H-shaped support unit is buriedinto the riverbed; and the monitoring unit is arranged in the H-shaped support unit and buried into the riverbed. The monitoring unit sends out the sensing signal when the monitoring unit is exposed outside the riverbed in the case of the structural change of the riverbed, and then the structural change of the riverbed can be learned through analysis of the sensing signal so as to facilitate subsequent processing and warning.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device for monitoring the structural change of a river bed. Background technique [0002] In the geographical environment with severe terrain fluctuations and turbulent rivers, coupled with the influence of human factors such as over-development of hillsides and illegal mining of sand and gravel, the riverbed is hollowed out, the erosion situation is intensified, and soil-rock flow problems such as hillside slides are caused, especially for bridges. Security is a serious threat. [0003] The main purpose of the bridge scour monitoring device is to immediately respond to the scour depth of the bridge foundation to judge the safety of the bridge. [0004] see figure 1 , is an existing method for monitoring the hollowing out depth of a bridge foundation, mainly burying three monitoring devices 900 in the riverbed 920 near the pier 910 of the bridge, and judging the depth of the ...

Problems solved by technology

[0005] Although the existing method can achieve the purpose of monitoring the depth of the riverbed 920, the monitoring device 900 will be taken away with the erosion of river water or earth and rocks, and not only cannot be recycled, but will also become waste in the downstream river

In addition, each monitoring device 900 must be equipped with a power supply, such as a battery, so that the circuit in it can operate normally and send out a signal, which further results in a waste of production cost.

[0006] This shows that the above-men
