In this embodiment, when a file in the file cabinet 38 catches fire, the high-pressure air pump 1 is started first, the high-pressure air pump 1 supplies air to the dry powder bin 3 through the air supply pipeline 2, the high-pressure nozzle 4 at the upper end of the dry powder bin 3 blows compressed air to the dry powder extinguishing agent in the dry powder bin 3, the dry powder extinguishing agent is blown up and then blown to the electromagnetic directional valve 8 through the dry powder pipeline 6, and when the high-pressure nozzle 4 blows the dry powder extinguishing agent in the dry powder bin 3, the high-pressure nozzle can blow the air baffle sheet 301 on the dry powder inner bin 306, so that the air baffle sheet 301 drives the dry powder inner bin 306 to rotate, and thus the high-pressure nozzle 4 can be uniformly blown in the dry powder inner bin 306; the blown dry powder extinguishing agent sometimes falls to the bottom end of the dry powder outer bin 307, and the lower nozzle 5 at the bottom end of the dry powder bin 3 can continuously blow the dry powder extinguishing agent, so that waste is avoided.
The dry powder extinguishing agent blown to the electromagnetic directional valve 8 through the dry powder pipeline 6 can be blown to the working pipeline 9 through the electromagnetic directional valve 8, the dry powder extinguishing agent blown to one side through the working pipeline 9 can be blown to the high-pressure hose 25 on one side through the reversing fixed block 21 and the reversing movable block 22, the dry powder extinguishing agent blown to one side through the high-pressure hose 25 can pass through the nozzle fixed block 29, a part of the dry powder extinguishing agent blown out through the nozzle fixed block 29 can be blown out through the gas jet holes 30, at the moment, the nozzle fixed block 29 can move along the shifting slide block 26 to the opposite direction of the sprayed gas, the shifting slide block 29 can drive the shifting slide block 26 to move together to the opposite direction of the sprayed gas in the moving process, at the moment, the shifting slide block 26 can drive the reversing movable block 22 and the tension spring 24 to move through the pull rod 23, when the ventilation holes of the reversing movable block 22 move to the middle positions of the high-pressure hoses 25 on two sides, under the action of inertia, the reversing moving block 22 and the shifting slide block 26 move forwards continuously, at the moment, the tension spring 24 pulls the pull rod 23 upwards, the pull rod 23 drives the reversing moving block 22 to move continuously, the reversing moving block 22 changes the air inlet end of the high-pressure hose 25 to realize reverse air injection of the air injection hole 30, and therefore reciprocating motion of the nozzle fixing block 29 is realized, and the fire extinguishing area of the nozzle 32 is increased.
Another part of the dry powder extinguishing agent passing through the nozzle fixing block 29 is sprayed out along the nozzle 32 after passing through the rubber film 35, the rubber film 35 expands in the air spraying process to drive the extension spring 33 to stretch, and at the same time, the nozzle 32 moves downwards under the driving of the spring fixing plate 34, so that the nozzle 32 is facilitated to be closer to a fire source, and the fire can be better extinguished.
After the fire extinguishing is finished, the electromagnetic directional valve 8 is reversed, the air supply pipeline 2 supplies air to the working pipeline 9 and the air motor pipeline 10, and the clean air blows the dry powder fire extinguishing agent in the working pipeline 9 to the file cabinet 38; the air motor pipe 10 will supply air to the air motor 11, so that the air motor 11 will drive the conveyor belt 13 to move, thereby transporting the dry powder extinguishing agent falling from the bottom of the file cabinet 38 onto the conveyor belt 13 out of the file cabinet 38.
