Reservoir bank hydro-fluctuation belt landslide and collapse array-type early-warning system

Abstract

The invention discloses a reservoir bank hydro-fluctuation belt landslide and collapse array-type early-warning system, which comprises a 3*3 array composed of tilted alarms. Each tilted alarm is connected with a total control device through a wire. Each tilted alarm comprises a shell, wherein a power supply device and a monitoring device which are connected with each other are arranged in the shell from top to bottom in sequence, and a fixing part is connected to the lower end of the shell. When the water level of a reservoir is lowest, namely a hydro-fluctuation belt is in the maximum exposed area state, the reservoir bank hydro-fluctuation belt landslide and collapse array-type early-warning system can be arranged in a reservoir bank hydro-fluctuation belt area with the landslide or collapse risk; once a soil body is tilted or displaces, the resistance value of photoresistors is changed along with the change of the illumination intensity due to tilting, at the moment, a micro-current electric signal receiver transmits information to a processing module, after processing and identification, early-warning information is issued through a transmitting module, residents are helped toevacuate in time, reservoir management personnel are informed to conduct disposal, and the loss of life and property is avoided.

Description

Technical field [0001] The application relates to the field of geological disaster prevention in the water-level-fluctuating zone of a reservoir, and specifically to an array type early warning system for landslides and collapses of the water-fluctuating zone of a reservoir. Background technique [0002] Fluctuating zone is a unique area of ​​rivers, lakes, and reservoirs. It refers to the fluctuating area formed between the highest water level and the lowest water level on the shore due to seasonal water level fluctuations and periodic water storage. Under natural conditions, the fluctuating zones of rivers and lakes have experienced long-term erosion and gradually stabilized, and the fluctuating zones are dominated by bedrock. The situation of the reservoir bank drawdown zone caused by artificial dam construction is quite different. Take the Three Gorges Hydropower Station as an example. After the completion of the Three Gorges Project, due to the artificial control of the hydr...

AI Technical Summary

Problems solved by technology

Although its early warning is more timely and the release of information is faster, its device is more complicated, it is not suitable for the water-fluctuation zone of the reservoir bank, and it is difficult to use it again

[0007] The problems we are currently facing are: (1) There are still very few studies on early warning devices for landslides and collapses in the reservoir bank drawdown zone, and the current research on this aspect is almost blank; (2) The current existing collapse early warning devices are mainly aimed at Highways, power grids, and power transmission equipment, they cannot be used in special ecologically fragile areas such as reservoir-bank drawdown zones; (3) The existing devices are of a single type, and the layout is difficult and costly, which cannot prevent false alarms
