FIG. 1 is a schematic structural diagram of a distribution box with automatic fire extinguishing function according to the present invention.

As shown in the picture: 1. Box, 2. Partition, 3. Smoke sensor, 4. Air inlet, 5. Solenoid valve, 6. PLC controller, 7. Fire extinguishing tank, 8. Nozzle, 9. Nozzle, 10. Fixer, 11. Exhaust fan, 12. Filter, 13. Ventilation hole.

Detailed ways

The present utility model will be further described in detail below in conjunction with the accompanying drawings.

With reference to the drawings, a power distribution box with automatic fire extinguishing function includes a box body 1, a partition 2 is arranged on the top of the box body 1, a smoke sensor 3 is arranged at the bottom of the partition plate 2, and the box body 1 The top is provided with an air inlet 4, a solenoid valve 5 is installed on the air inlet 4, a PLC controller 6 is arranged on the inner wall of the box body 1, and a fire extinguishing tank 7 is arranged inside the box body 1, and the fire extinguishing tank 7 The top is provided with a spray head 9 connected by a nozzle 8, the spray head 9 is fixed on the inner wall of the box body 1 by a holder 10 and is electrically connected to the PLC controller 6, and the bottom of the outer surface of the box body 1 is provided with an electrical connection to the The exhaust fan 11 of the PLC controller 6 is connected with a wireless communication module.

The number of the fire extinguishing tanks 7 is two, and the inside is filled with high-pressure gas and sodium bicarbonate powder.

A filter screen 12 is provided on the air inlet end of the top of the solenoid valve 5 , and the solenoid valve 5 is electrically connected to the PLC controller 6 .

Several ventilation holes 13 are evenly distributed on the partition plate 2 .

The smoke sensor 3 is electrically connected to the PLC controller 6 .

The wireless communication module is a GRM530 wireless communication module.

The utility model works through the exhaust fan, the pressure in the box is reduced, the air enters from the air inlet through the electromagnetic valve, and under the action of the partition, the air fills the cavity of the box located on the upper side of the partition, so that the air is evenly distributed downward along the ventilation holes. Blow into the box to cool down the internal components, and then the heat is extracted by the exhaust fan, so as to ensure that the internal temperature will not be too high, and it is not easy to catch fire; once the inside of the box is on fire, it will be detected by the smoke sensor, and the signal will be transmitted to the PLC The controller, the PLC controller controls the solenoid valve to work and close, so that the box forms a closed chamber, the air is continuously reduced, and the fire source will be slowly extinguished if there is a lack of oxygen. The fire alarm information is sent to the remote terminal to remind the staff to come and check, and the fire extinguishing tank will be activated to extinguish the fire inside the box.

The air inlet at the top of the box and the solenoid valve form an air cut-off mechanism. The PLC controller is electrically connected to the solenoid valve to control the solenoid valve to work so that no air can enter the box, while the exhaust fan works, causing the air in the box to decrease sharply, resulting in hypoxia. Fire extinguishing, the intake end of the solenoid valve is provided with a filter to prevent dust from entering, and the ventilation holes on the partition are used for heat dissipation, which can allow the wind energy to be blown evenly, increase the blowing area, and have a better heat dissipation effect.

The present invention and the embodiments thereof have been described above, and the description is not restrictive, and what is shown in the accompanying drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto.
