AI Technical Summary
Existing automatic explosion-proof devices for mining use rely on a single sensor to control the opening of the internal flame-retardant explosion-proof device. The lack of an auxiliary triggering structure results in the device failing to open in a timely manner and causing a decrease in accuracy.
A fast-triggering automatic explosion-proof device for mining was designed. The device monitors the internal environment of the mine through a visual detection module. When a fire is detected, the device controls the operation of a servo motor, which drives the gear and rack to move downwards, presses down the trigger switch, and controls the operation of the airflow module and the dry powder fire extinguishing module. The device also combines an airflow sensing module and a photosensitive sensor to improve monitoring accuracy.
It enables rapid and accurate triggering of the flame-retardant explosion-proof device during an explosion, improving monitoring accuracy, ensuring timely fire extinguishing, and preventing secondary disasters.

TECHNICAL FIELD
[0001] The utility model relates to the field of mine explosion-proof device, especially relates to quick trigger's mine automatic explosion-proof device. BACKGROUND
[0002] The mine explosion-proof device generally utilizes the principle that the air shock wave speed generated by explosion is much greater than the flame speed, triggers the flame-retardant explosion-proof device when the air shock wave arrives, and thus releases the fire extinguishing powder in advance to block the flame and prevent other secondary disasters from occurring in the mine.
[0003] The existing mine automatic explosion-proof device controls the opening of the internal flame-retardant explosion-proof device through a single sensor when in use, lacks an auxiliary triggering structure, and thus may fail to open the flame-retardant explosion-proof device in time when an explosion occurs.
[0004] Therefore, in view of the above-mentioned problem that the existing mine automatic explosion-proof device controls the opening of the internal flame-retardant explosion-proof device through a single sensor when in use and lacks an auxiliary triggering structure, a quick trigger's mine automatic explosion-proof device can be designed, the environment inside the mine can be monitored through the setting of a visual detection module, the controller controls the operation of the servo motor when the explosion is monitored to produce light, the output end of the servo motor drives the first gear to rotate, the first gear drives the rack to move downward, and thus drives the pressing connecting rod to press down the trigger switch, so as to control the operation of the air flow module and the dry powder fire extinguishing module.

[0007] Preferably, a visual detection module can monitor the environment inside the mine. When an explosion is detected and a flame is detected, the controller controls the servo motor to operate. The output of the servo motor drives the first gear to rotate, and the first gear drives the rack to move downward, thereby driving the pressing linkage to press down the trigger switch. This controls the operation of the airflow module and the dry powder fire extinguishing module. This solves the problem that the existing mine automatic explosion-proof devices use a single airflow pressure sensor for monitoring without an auxiliary triggering structure, which is prone to accuracy degradation.

[0011] Preferably, a slider is installed on the rear surface of the rack, and the rack is slidably connected to the explosion-proof box through the slider.
[0012] Preferably, the bottom surface of the explosion-proof enclosure is symmetrically provided with mounting bases, and each mounting base is rotatably connected to a rotating shaft. A baffle is installed between the two rotating shafts, and a photosensitive sensor is installed at the front position of the bottom surface of the explosion-proof enclosure.
[0013] Preferably, the baffle is made of black rubber sponge material.
[0014] The beneficial effects of this utility model are:
[0015] 1. By setting up a visual detection module, the environment inside the mine can be monitored. When an explosion occurs and a flash of light is detected, the controller controls the servo motor to operate. The output of the servo motor drives the first gear to rotate, and the first gear drives the rack to move downward, thereby driving the pressing linkage to press down the trigger switch. This controls the operation of the airflow module and the dry powder fire extinguishing module. This solves the problem that the existing mine automatic explosion-proof devices use a single airflow pressure sensor for monitoring without an auxiliary triggering structure, which is prone to accuracy degradation.
