An explosion-proof pressure relief and energy storage reset damper with electromagnetic lock release and its control method

Abstract

The invention discloses an explosion-proof pressure-relief and energy-storage reset damper with electromagnetic lock release and a control method, comprising a roadway and a damper bracket fixedly connected around the roadway, the damper bracket is provided with a damper, the damper includes a door frame, and The door leaf mechanism, the limit reset mechanism controlling the reset of the door leaf mechanism and the explosion overpressure monitoring system arranged in the roadway; the door leaf mechanism includes the upper door leaf, the lower door leaf and the pulley mechanism connecting the upper door leaf and the lower door leaf; the limit reset mechanism includes the The limiter at the top of the roadway, the water tank, the water pipe and the solenoid valve for controlling the water pipe; the explosion overpressure monitoring system includes several sensors, data transmission lines and processors arranged in the roadway, and the explosion overpressure monitoring system is electrically connected to the limit reset mechanism . When the explosion shock wave reaches the damper, the pressure relief door leaf can be opened to allow the shock wave to pass through without damaging the damper, and it will automatically reset after the shock wave passes through. The damper can be reused many times to prolong the service life of the damper.

Description

technical field [0001] The invention relates to the technical field of mine roadway dampers, in particular to an explosion-proof pressure relief and energy storage reset damper with electromagnetic lock release and a control method. Background technique [0002] The damper is a ventilation structure that partitions the roadway in the coal mine and allows pedestrians and vehicles to pass through. It plays an indispensable role in coal mine underground. Once a gas or coal dust explosion occurs underground in a coal mine, high flame temperature, shock wave overpressure and toxic and harmful gases will be generated, resulting in the casualties of a large number of workers in the confined space underground. At the same time, the shock wave will cause irreversible damage to the existing ordinary damper. Once the damper structure is broken, it will lose its function of isolating ventilation, which will change the original ventilation situation underground, resulting in short circu...

AI Technical Summary

Problems solved by technology

[0005] 1. The existing damper does not have the function of large-area pressure relief in the event of an explosion disaster, and the power of the shock wave will be intensified after the explosion occurs;

[0006] 2. The existing damper does not have the function of repeated use in the event of an explosion disaster, and will lose its original function after the explosion disaster;
