A new active fireproof distribution box
ActiveCN115764576Bprevent proliferationGuarantee personal safetyClimate change adaptationSubstation/switching arrangement cooling/ventilationSmoke EmissionMechanical engineering
The application discloses a novel active fireproof distribution box in the technical field of distribution boxes, which comprises a box body, and circular shafts are fixedly installed at the back of both sides of the inner cavity of the box body. The high-pressure cavity, electromagnetic valve, circular air bag and first thorn needle are arranged. When a fire breaks out inside the box body, dense smoke will be continuously generated inside the box body. At this time, the two smoke sensors can sense the generation of the dense smoke and send a signal to the controller. The controller will control the electromagnetic valve to open. At this time, the high-pressure gas in the high-pressure cavity can enter the inside of the bottom cavity. Under the action of the air pressure, the moving plate can drive the first thorn needle to move downward. Finally, the bottom end of the first thorn needle can puncture the circular air bag, so that the circular air bag is burst open. At this time, the dry powder in the circular air bag can be scattered downward, so that the effect of extinguishing the fire source inside the box body can be achieved, and the active fireproof purpose is effectively achieved.
