[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1-4As shown in the figure, an electrical cabinet with a safety protection device provided in this embodiment of the utility model includes a cabinet body 1. A spray pipe 2 is rotatably connected inside the cabinet body 1, and the top end of the spray pipe 2 extends to the outside of the cabinet body 1. A nozzle 3 is fixedly installed on the outer wall of the spray pipe 2. A transmission box 13 is fixedly installed on the top of the cabinet body 1, and a driven gear 4 is installed on the outer wall inside the transmission box 13 where the spray pipe 2 is located. A motor 5 is fixedly installed on the outer wall at the top of the transmission box 13, and a driving gear 6 is installed on the output shaft of the motor 5.

A pump body 8 is fixedly installed on the top of the storage box 7. An extraction pipe 9 is installed on the output end of the pump body 8 and inserted into the storage box 7. The top end of the spray pipe 2 is rotatably connected to a connecting pipe 10 through a sealed bearing. One end of the connecting pipe 10 is connected to the output end of the pump body 8. A smoke sensor 11 is fixedly installed on the inner wall of the cabinet body 1. A controller 12 is fixedly installed on the outer wall of one side of the cabinet body 1. The smoke sensor 11 and the pump body 8 are electrically connected to the controller 12 through wires.
[0026] This utility model provides an electrical cabinet with a safety protection device, comprising a cabinet body 1, a spray pipe 2 rotatably connected inside the cabinet body 1, with the top end of the spray pipe 2 extending to the outside of the cabinet body 1, and a nozzle 3 fixedly mounted on the outer wall of the spray pipe 2. A transmission box 13 is fixedly mounted on the top of the cabinet body 1, and a driven gear 4 is mounted on the outer wall inside the transmission box 13 where the spray pipe 2 is located. A motor 5 is fixedly mounted on the outer wall at the top of the transmission box 13, and a driving gear 6 is mounted on the output shaft of the motor 5. The driving gear 6 and the driven gear 4 mesh with each other. A storage box 7 is fixedly mounted on the outer wall at the rear of the cabinet body 1, and a pump body 8 is fixedly mounted on the top of the storage box 7. The output end of the pump body 8 is provided with a nozzle that inserts into the storage box 7. The top of the extraction pipe 9 and the spray pipe 2 are rotatably connected to the connecting pipe 10 through a sealed bearing, and one end of the connecting pipe 10 is connected to the output end of the pump body 8. A smoke sensor 11 is fixedly installed on the inner wall of the cabinet body 1, and a controller 12 is fixedly installed on the outer wall of one side of the cabinet body 1. The smoke sensor 11 and the pump body 8 are electrically connected to the controller 12 through wires. When the cabinet body 1 catches fire, smoke will be generated. The smoke sensor 11 will detect the smoke in time and transmit the signal to the controller 12 to start the pump body 8. The pump body 8 draws the fire extinguishing agent in the storage box 7 into the interior of the connecting pipe 10 through the extraction pipe 9, so that the fire extinguishing agent enters the interior of the spray pipe 2 and is sprayed into the interior of the cabinet body 1 through the nozzle 3, which can automatically extinguish the fire when it first starts.
[0027] When the smoke sensor 11 detects smoke generated by a fire, it transmits a signal to the controller 12. The controller 12 then activates the pump 8 to draw the extinguishing agent into the spray pipe 2 and sprays it out through the nozzle 3. This allows for timely fire suppression as soon as the fire starts, minimizing potential losses. Furthermore, the spray pipe 2 can be rotated while spraying the extinguishing agent, increasing the spray range and improving extinguishing efficiency. This demonstrates the high safety protection function of the electrical cabinet.
[0028] In one embodiment provided by this utility model, such as Figure 2 and Figure 4 As shown, the cabinet body 1 has a sliding connection to the mounting plate 14 inside, and a moving block 15 is provided on the outer wall of the bottom of the mounting plate 14. When the moving block 15 moves, it will drive the mounting plate 14 to move synchronously.
[0029] In another embodiment provided by this utility model, such as Figure 2 and Figure 4 As shown, a lead screw 16 is rotatably connected to the inner wall of the cabinet body 1 via a bearing, and a movable block 15 is threaded onto the outside of the lead screw 16, enabling the movable block 15 to move axially on the lead screw 16.
[0030] In another embodiment provided by this utility model, such as Figure 2 and Figure 4 As shown, a protective cover 17 is fixedly installed on the outer wall of the rear side of the cabinet body 1, and a toothed ring 18 is installed on the outer wall inside the protective cover 17. The two toothed rings 18 are externally meshed with a transmission chain 19. The protective cover 17 is used to prevent the staff from accidentally touching the toothed rings 18 and the transmission chain 19.
[0031] In one embodiment provided by this utility model, such as Figure 2 and Figure 4 As shown, a motor 20 is fixedly installed on the outer wall of the rear side of the cabinet body 1. One end of a lead screw 16 is installed on the output shaft of the motor 20, and the motor 20 can drive the lead screw 16 to rotate.
[0032] In another embodiment provided by this utility model, such as Figure 1 , 2 and Figure 4 As shown, guide seats 21 are provided on the inner walls of both sides of the cabinet body 1, and guide blocks 22 are fixedly provided on both sides of the outer wall of the bottom of the mounting plate 14. The guide blocks 22 are slidably connected inside the guide seats 21, which can guide the mounting plate 14.
[0033] In another embodiment provided by this utility model, such as Figure 1As shown, several rollers 23 are rotatably connected to the inner wall of the guide block 22 via a rotating shaft, and the rollers 23 are rotatably connected inside the guide seat 21, which makes the mounting plate 14 move more smoothly.
[0034] Working principle: When a fire breaks out inside the cabinet body 1, smoke will be generated. The smoke sensor 11 will detect the smoke in time and transmit the signal to the controller 12. The controller 12 will start the pump body 8. The pump body 8 will draw the fire extinguishing agent from the storage tank 7 into the connecting pipe 10 through the extraction pipe 9. Then, it will enter the spray pipe 2 through the connecting pipe 10 and spray it into the cabinet body 1 through the nozzle 3. This can automatically extinguish the fire at the beginning of the fire, minimizing the damage. At the same time as the fire extinguishing agent is sprayed, the motor 5 can drive the drive gear 6 to rotate and the driven gear 4 to mesh. This will cause the driven gear 4 to drive the spray pipe 2 and the nozzle 3 to rotate. It can expand the spray range of the extinguishing agent, making the fire extinguishing efficiency higher. When it is necessary to repair the electrical equipment on a certain mounting plate 14, the motor 20 driving the mounting plate 14 is started to drive one of the lead screws 16 to rotate. The lead screw 16 drives the gear ring 18 to rotate. The gear ring 18 drives another lead screw 16 parallel to the lead screw 16 to rotate through the transmission chain 19. This allows the two lead screws 16 to rotate simultaneously and thread with the moving block 15, so that the moving block 15 synchronously drives the mounting plate 14 to move axially on the lead screw 16. This allows the mounting plate 14 to be moved toward the opening of the cabinet body 1, which is convenient for repairing the electrical equipment on the mounting plate 14.
[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
