Further, the elevating motor 22 can drive the threaded screw 23 to rotate when operating, and then can drive the sliding nut 24 to move up and down outside the threaded screw 23, and when the sliding nut 24 moves up and down, the connecting rod 25 can also drive the moving plate 32 to move up and down, and then can drive the nozzle 322 to move up and down, so that the fire extinguishing agent sprayed from the nozzle 322 can be uniformly blown to each electrical component in the cabinet 10.

The lifting outer cylinder 21 is fixedly connected with the cabinet body 10, and the bottom end of the threaded screw rod 23 is rotatably connected with the lifting outer cylinder 21 through a bearing seat 26.

Wherein, the PLC controller is electrically connected with the lifting motor 22 and the air cylinder 36 respectively.

Wherein, still include: a smoke sensor 70.

In this embodiment, the smoke sensor 70 is specifically model GQQ 5.

Wherein, the smoke sensor 70 is fixedly installed at one side of the inner wall of the cabinet 10.

Further, the smoke sensor 70 is used for detecting a smoke signal in the cabinet 10 in real time and transmitting the detected smoke information to the PLC controller.

Wherein, the PLC controller is electrically connected with the smoke sensor 70.

As described in the above embodiments, when the smoke sensor 70 detects that a fire source occurs in the cabinet 10 due to a short circuit, the smoke sensor 70 transmits a detected signal to the PLC controller, the PLC controller stops the operation of the fan 52 after processing and analyzing, then controls to open the air pump 33, the electromagnetic pulse valve 34, the air cylinder 36 and the lifting motor 22, the air cylinder 36 operates to drive the thimble 37 to move downward, the film 314 can be punctured by the thimble 37, so that the dry powder fire extinguishing agent in the powder storage chamber 312 can be sprayed out from the powder spraying port to the mixing chamber 313, then the gas injected by the air pump 33 is brought into the air spraying pipe 321, and finally the gas is sprayed out from the nozzle 322, the sprayed dry powder fire extinguishing agent can perform fire extinguishing treatment on the electrical components, and at the same time, the up-down automatic fire extinguishing treatment can be performed in cooperation with the lifting mechanism 20, and the fire extinguishing treatment can be performed at the first time, avoiding causing larger fire accidents.

In the several embodiments provided in the present invention, it should be understood that the disclosed apparatus may be implemented in other ways. The welding or screwing or winding of the parts to be welded or screwed together as shown or discussed can be assisted by means of devices such as welding torches, screwing with wrenches, etc., and the parts of the device can be made of various materials, such as metal materials, for example, aluminum alloys, steel and copper, by casting or by mechanical stamping.
