Flywheel type rockfall protection net buffering energy dissipation device and disaster early warning system

Abstract

The invention particularly provides a flywheel type rockfall protection net buffering energy dissipation device and a disaster early warning system. The flywheel type rockfall protection net energy dissipation device mainly comprises a steel rope, a flywheel, a reset spring and a power generation transmission shaft. The invention further provides a disaster early warning system based on the flywheel type rockfall protection net buffering energy dissipation device. The disaster early warning system mainly comprises the flywheel type buffering energy dissipation device, a power generation module, a rockfall energy level judgment and alarm control module, a field alarm issuing module and a remote alarm information transmission module. The flywheel type buffering energy dissipation device is installed on a rockfall protection net, rockfall drives the flywheel to provide power to the power generation module, the disaster level is determined through the rockfall energy level judgment and alarm control module, and information is transmitted through the field alarm issuing module and the remote alarm information transmission module. According to the flywheel type rockfall protection net buffering energy dissipation device, the kinetic energy of rockfall impact can be buffered and reduced, the monitoring and early warning of rockfall disasters can be realized, and the harm caused by road slope collapse and rockfall disasters can be avoided and reduced to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of geological disaster safety protection and disaster early warning, in particular to a flywheel type rockfall protection net buffer energy dissipator and disaster early warning system. Background technique [0002] Rockfall refers to the rapid movement of the slope rock block from the surface of the geological body after falling, rebounding, jumping, rolling or sliding, etc., along the slope, and finally falls on a relatively gentle area or obstacle. A kinetic evolution process that comes to a standstill nearby. Rockfall is a common geological disaster in mountainous areas. Its causes are complex and sudden, and the environment is steep and hidden. It is difficult to investigate, scattered in distribution, poor in regularity, and difficult to predict. It poses a great threat to people's lives and property. [0003] At this stage, in order to solve this problem, the combination of protection and early warni...

AI Technical Summary

Problems solved by technology

The limited elastic recovery ability and unstable anti-friction ability of the friction braking ring in the ring buffer restrict its buffering ability

[0005] 2. The ring buffer only plays the role of buffering and dissipating energy when the rockfall impacts, and it is not combined with the rockfall alarm, so it cannot provide a disaster alarm function when the rockfall disaster occurs

[0006] 3. Methods such as manual detection and early warning cannot timely know the situation of rockfall disasters, and personal safety cannot be guaranteed
