Damming disaster early warning device and monitoring early warning method based on tethered balloon

Abstract

The invention relates to a damming disaster early warning device and a monitoring early warning method based on a tethered balloon, and relates to the field of early warning and monitoring of geological disasters. The device includes a plurality of balloon observation equipment carrying environmental image acquisition devices, wherein the plurality of pieces of balloon observation equipment are respectively arranged in the area of the survey and dam and are used to photograph and sample the damming situation in the damming area, and perform disaster early warning by analysis. The damming disaster early warning device and monitoring early warning method based on the tethered balloon provided by the invention make improvement for the characteristics such as remoteness of the dam disaster, backward monitoring methods, complicated terrain, and difficult layout.

Description

technical field [0001] The invention relates to a damming disaster early warning device and a monitoring and early warning method based on a tethered balloon, and the invention relates to the field of early warning and monitoring of geological disasters. Background technique [0002] Landslides, rock avalanches, and debris flows often occur on river banks in mountainous areas due to factors such as rainfall, snowmelt, and earthquakes. These moving soils form dams in the river channel, and upstream water accumulates under the obstruction of dams to form a dammed lake. Since the anti-sliding, anti-seepage and anti-scouring capabilities of barrier lakes are often very poor, once a breach occurs, the accumulated lake water will cause great destructive power and have a great impact on life and property downstream. [0003] At present, geological disasters occur frequently all over the world, and large-scale barrier lakes are also formed from time to time. It is difficult to pred...

AI Technical Summary

Problems solved by technology

It is difficult to predict the time when the barrier dam is extremely unstable. The existing countermeasures are early detection and early treatment, reducing the accumulation of barrier lakes, and timely diverting water for discharge

As far as the applicant knows, the existing early warning methods have defects such as time lag and lack of data during disasters, and there are also certain difficulties in post-disaster tracking
