The power switch of the motor, the motor stops running, and the suction fan and blowing fan in the distribution box stop running. The blowing fan starts to run, and the operation of the suction fan and the blowing fan dissipates heat to the components in the distribution box to prevent fires caused by overheating. When the temperature is higher than 57°C, the switchgear group disconnects the power switch of the motor, and the motor stops running. The suction fan and blower fan in the distribution box stop running. At this time, a fire broke out in the distribution box. The fire extinguishing system will extinguish the fire in the distribution box. Fire extinguishing effect.

Embodiment three

Through the setting of the switchgear group 5, the switchgear group 5 provides the power interruption of the motor 2. The switchgear group 5 contains a smoke controller and a temperature sensor controller. By collecting the smoke signal in the distribution box, it is judged that the distribution box has In case of fire, the switchgear group 5 disconnects the power switch of the motor 2 at this time, the motor 2 stops rotating, the suction fan 35 and the blowing fan 314 in the distribution box stop rotating, and by collecting the temperature signal in the distribution box, when the temperature is lower than 30 When the temperature is higher than 30°C, the switchgear group 5 turns off the power switch of the motor 2, and the suction fan 35 in the distribution box stops running. When the temperature is higher than 30°C, the switchgear group 5 turns on the power switch of the motor 2, and the motor 2 drives the A rotating rod 21 rotates, the fifth conical tooth 31 is fixedly connected to the surface of the first rotating rod 21 and can drive the sixth conical tooth 33 to rotate, and the fourth rotating rod 32 drives the ninth conical tooth 33 under the action of the sixth conical tooth 33 The conical tooth 39 rotates, and the tenth conical tooth 311 makes the sixth rotating rod 310 drive the eleventh conical tooth 312 to rotate under the action of the ninth conical tooth 39, and the twelfth conical tooth 316 rotates on the eleventh conical tooth 316. Under the action of the shaped teeth 312, the seventh rotating rod 315 drives the second fan blade 317 to rotate, and the rotation of the second fan blade 317 has a blowing effect on the inside of the box body 1. When the fourth rotating rod 32 rotates, the seventh conical tooth 34 drives the second fan blade 317 to rotate. The eight conical teeth 37 rotate, and the fifth rotating rod 36 rotates under the action of the eighth conical teeth 37, and the first fan blade 38 rotates to realize the effect of the first fan blade 38 on the power distribution box. The suction fan 35 and the blower fan The rotation of 314 plays a role of heat dissipation and dust removal for the distribution box, preventing fires caused by excessive temperature. When the temperature is higher than 57°C, the switchgear group 5 disconnects the power switch of the motor 2, and the motor 2 stops rotating. The suction fan 35 and the blower fan 314 in the distribution box stop rotating. At this time, a fire broke out in the distribution box. The fire extinguishing system puts out the fire in the distribution box. The suction fan 35 and the blower fan 314 stop running to avoid air flow in the distribution box. Affect the fire extinguishing effect.
