Description

Technical Field

[0001] The utility model relates to the technical field of coal mine flame retardancy and explosion isolation, in particular to a coal mine flame retardancy and explosion isolation device with multifunctional jetting. Background Art

[0002] Mine explosion-proof and flame-retardant devices generally use the principle that the speed of the air shock wave generated by the explosion is much greater than the speed of the flame. When the air shock wave arrives, the flame-retardant and explosion-proof device is triggered, thereby releasing the fire extinguishing powder in advance to block the flame and prevent other secondary disasters from occurring in the mine.

[0003] Existing coal mine flame retardant and explosion-proof devices are usually installed inside the mine when in use. The mine is usually filled with a large amount of fly ash, which will adhere to the outer surface of the air shock wave sensor module, resulting in a decrease in detection sensitivity or even failure to trigger.

[0004] Therefore, in order to address the problem that the above-mentioned existing coal mine flame retardant and explosion-proof device does not have the function of cleaning the sensor module during use, resulting in a decrease in detection accuracy, a multi-functional spraying coal mine flame retardant and explosion-proof device can be designed. By setting a driving motor, its output end will drive the screw to rotate during operation, and the screw will drive the movable seat threadedly connected to it to move back and forth in the left and right directions. The movable seat drives the connecting rod and the soft hair disk to move synchronously, so that the soft hair disk can wipe the outer surface of the airflow sensing module. Utility Model Content
