[0023] The length of the horizontal pipe of the device and the number of spray heads 6 can be customized according to the number of electrical cabinets. Place each spray head 6 in each electrical cabinet. When a fire occurs, the flame sensor 7 detects the flame signal and transmits it to the controller. The controller then controls the opening of the switching valve. The fire extinguishing agent in the fire extinguishing tank 2 enters the connecting pipe 4 through the horizontal pipe 3, then flows into the corresponding vertical pipes 1 5 according to the number of electrical cabinets, and finally sprays out from the spray heads 6 placed in each electrical cabinet. At the same time, the motor 81 starts to drive the driving wheel 82 to rotate, and through the transmission of the first belt 84 and the second belt 85, the driven wheel 83 is driven to rotate, thereby driving the vertical pipe 1 5 and the spray head 6 to rotate, so as to expand the fire extinguishing coverage area and achieve efficient fire extinguishing for multiple groups of electrical cabinets. This non-pressure storage fire extinguishing device for an electrical cabinet can efficiently extinguish fires for multiple groups of electrical cabinets at the same time, ensure a rapid response and control of the fire when a fire occurs, thereby effectively protecting the equipment safety and reducing the fire loss.

[0032] Working principle:

[0033] The length of the horizontal pipe of the device and the number of groups of the nozzles 6 can be customized according to the number of electrical cabinets. Each nozzle 6 is placed in each electrical cabinet. When a fire occurs, the flame sensor 7 detects the flame signal and transmits it to the controller. The controller then controls the opening of the switch valve. The fire extinguishing agent in the fire extinguishing tank 2 enters the connecting pipe 4 through the first horizontal pipe 3, then flows into the first vertical pipes 5 corresponding to the number of electrical cabinets, and finally sprays out from the nozzles 6 placed in each electrical cabinet. At the same time, the motor 81 starts to drive the driving wheel 82 to rotate, and through the transmission of the first belt 84 and the second belt 85, the driven wheel 83 is driven to rotate, thereby driving the first vertical pipes 5 and the nozzles 6 to rotate, so as to expand the fire extinguishing coverage area and realize the efficient fire extinguishing of multiple groups of electrical cabinets. This non-pressure storage fire extinguishing device for electrical cabinets can efficiently extinguish multiple groups of electrical cabinets at the same time, ensure a rapid response and control of the fire when a fire occurs, thereby effectively protecting the equipment safety and reducing fire losses;

[0034] When a fire occurs, the controller starts the operation of the vacuum pump 9. The suction force generated by the vacuum pump 9 enables air to enter the second horizontal pipe 10 through the second vertical pipes 11 corresponding to the number of electrical cabinets, realizing the vacuum pumping treatment inside multiple groups of electrical cabinets, which can further improve the fire extinguishing effect and rate;
