Problems solved by technology

[0002] The trigger mechanism used in the explosion-proof devices used in existing coal mines is generally a passive flame-proof device mechanical trigger mechanism, which acts the shock wave generated by the explosion on the trigger baffle, causing the baffle to drive the slider forward, and the valve body The steel ball on the upper slides into the keyway in the slider, the valve core is displaced under the action of the spring, and at the same time the high-pressure chamber is opened, and the high-pressure gas pushes the dry powder in the powder storage cylinder to be ejected; this mechanical trigger mechanism is mostly used for Pressure storage type explosion-proof device, insufficient sealing will lead to insufficient storage pressure, which cannot meet the spraying effect
Thirdly, since the high-pressure gas is stored in it, there will be certain safety risks in the process of transportation and installation

Abstract

The invention provides a magneto-electric triggering mechanism for an explosion-proof device. The mechanism comprises a triggering baffle plate, a sliding block, a valve block, a valve element, a magnetic core, a coil and lead terminals. According to the mechanism, the magnetic core is driven by the elasticity of a spring to cut a magnetic line of force in the coil to convert mechanical energy into electric energy, and a gas generator is used for triggering a passive explosion-proof device; the working stability and safety of the passive explosion-proof device are improved, the reaction time of the passive explosion-proof device is shortened, explosion suppression efficiency is improved, the misoperation of the explosion-proof device is reduced oreven completely eradicated, safety production of a coal mine is ensured, and potential hazards are avoided.

Description

technical field [0001] The invention belongs to the field of electromagnetism and relates to a magneto-electric trigger mechanism, in particular to a magneto-electric trigger mechanism for an explosion-proof device. Background technique [0002] The trigger mechanism used in the explosion-proof devices used in existing coal mines is generally a passive flame-proof device mechanical trigger mechanism, which acts the shock wave generated by the explosion on the trigger baffle, causing the baffle to drive the slider forward, and the valve body The steel ball on the upper slides into the keyway in the slider, the valve core is displaced under the action of the spring, and at the same time the high-pressure chamber is opened, and the high-pressure gas pushes the dry powder in the powder storage cylinder to be ejected; this mechanical trigger mechanism is mostly used for Insufficient sealing of the pressure storage type explosion-proof device will lead to insufficient storage pres...
