DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The present application embodiment discloses an active fire-proof low-voltage withdrawable switch cabinet housing. Figure 1-5 An active fireproof low-voltage withdrawable switch cabinet housing includes a switch cabinet 1. The outer walls of the switch cabinet 1 are provided with heat dissipation holes 2 on both sides of the outer wall. The heat dissipation holes 2 facilitate heat dissipation inside the switch cabinet 1. The inner wall of the switch cabinet 1 located at the heat dissipation hole 2 is provided with an inner groove 12. The outer walls of the inner groove 12 on both sides are rotatably connected with threaded rods 13. An isolation plate 14 is arranged between the two threaded rods 13, and the isolation plate 14 is threadedly connected with the two threaded rods 13. By driving the two threaded rods 13 on both sides of the switch cabinet 1 to rotate, the two threaded rods 13 drive the isolation plate 14 to move downward, thereby The isolation plate 14 is used to block the heat dissipation hole 2, thereby isolating the inside of the switch cabinet 1 to prevent oxygen from supporting combustion, which is convenient for extinguishing the fire of the low-voltage switch cabinet. The inner wall of the switch cabinet 1 is provided with a smoke detection device 16, which is used to detect whether a fire occurs inside the switch cabinet 1. Two fire extinguishing nozzles 17 are provided on the outer walls on both sides of the smoke detection device 16, and the fire extinguishing nozzles 17 facilitate carbon dioxide to extinguish the fire inside the switch cabinet 1. The top outer walls on both sides of the switch cabinet 1 are provided with driving components for driving the two threaded rods 13, and the two threaded rods 13 can be driven by the driving components.

[0023] The top outer wall of the switch cabinet 1 is fixedly connected with a fire extinguishing agent storage and conveying device 4, and two delivery pipes 7 are arranged on the outer walls on both sides of the fire extinguishing agent storage and conveying device 4, and the fire extinguishing agent storage and conveying device 4 is connected with two fire extinguishing nozzles 17 through the two delivery pipes 7. The fire extinguishing agent storage and conveying device 4 is convenient for conveying carbon dioxide to the two fire extinguishing nozzles 17 through the delivery pipes 7, so as to facilitate fire extinguishing. The outer wall of the fire extinguishing agent storage and conveying device 4 is also provided with a receiver to receive the signal of whether to start.

[0024] The outer wall of the switch cabinet 1 on one side of the fire extinguishing agent storage and conveying device 4 is fixedly connected with a main controller 9, which is convenient for controlling the fire extinguishing agent storage and conveying device 4, the servo motor 11 and the alarm 10, thereby transmitting instructions to facilitate fire extinguishing inside the switch cabinet 1.

[0025] The driving assembly includes two driving boxes 8, which are arranged on both sides of the switch cabinet 1. Two threaded rods 13 rotate and penetrate the switch cabinet 1 and are fixedly connected to a worm gear 15. The outer wall of the driving box 8 on one side of the worm gear 15 is rotatably connected to a worm 18, and the worm 18 is meshed with the two worm gears 15. A servo motor 11 for driving the worm 18 is arranged on the outer wall of the driving box 8. A receiver is arranged on the outer wall of the servo motor 11, which is connected to the main controller 9. The servo motor 11 is controlled to switch on and off by the main controller 9, so that the output shaft of the servo motor 11 drives the worm 18 to rotate, so that the worm 18 drives the two worm gears 15 to rotate synchronously, so that the two worm gears 15 complete the driving of the two threaded rods 13.

[0026] A storage power supply component 5 is provided on the top outer wall of the switch cabinet 1, and the storage power supply component 5 is electrically connected to the main controller 9 and the servo motor 11. The storage power supply component 5 includes a DC-AC inverter, etc. The main controller 9, the servo motor 11, the alarm 10 and the servo motor 11 are easily powered independently through the storage power supply component 5 without being affected by the fire circuit breaker.

[0028] The implementation principle of the active fireproof low-voltage withdrawable switch cabinet housing of the embodiment of the present application is as follows: when a fire occurs inside the switch cabinet 1, smoke is generated inside the switch cabinet 1, and the inside of the switch cabinet 1 is detected by the smoke detection device 16, so that the smoke detection device 16 detects the smoke, and then the smoke detection device 16 is fed back to the main controller 9 through the feedback device on the smoke detection device 16, so that the data of the fire occurrence is transmitted to the servo motor 11 through the main controller 9, and then the servo motor 11 is started, so that the output shaft of the servo motor 11 drives the worm 18 to rotate, and then the worm 18 drives the two worm wheels 15 to rotate synchronously, and then the two worm wheels 15 drive the isolation plate 14 to move, so that the isolation plate 14 opens the heat dissipation hole 2 The main controller 9 transmits data to the receiver on the fire extinguishing agent storage and delivery device 4, thereby controlling the fire extinguishing agent storage and delivery device 4 to deliver carbon dioxide to the fire extinguishing nozzles 17 on both sides of the smoke detection device 16 through the delivery pipe 7, thereby causing the fire extinguishing nozzles 17 to spray carbon dioxide to extinguish the fire inside the switch cabinet 1. At the same time, the main controller 9 feeds back data to the alarm 10, causing the alarm 10 to sound an alarm, thereby reminding the staff. It is worth noting that the storage power supply component 5, as an independent storage power supply component, can power the fire extinguishing agent storage and delivery device 4, the storage power supply component 5, the alarm 10 and the servo motor 11.
