[0002] Switchgear is closed, and each branch circuit is set up according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switchgear, and have high-voltage busbars, such as power plants. Low-voltage switchgear is suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion.

[0003] Existing low-voltage switchgear mostly uses carbon dioxide for fire extinguishing. In the event of a fire, flames can enter the switchgear through the heat dissipation channels or overflow from the inside of the switchgear, thus failing to effectively suppress the flames and causing the fire to spread, thereby affecting safety. Therefore, this utility model provides a low-voltage switchgear with a fireproof device to solve the above problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a low-voltage switchgear with a fireproof device, including a switchgear body 1. A cabinet door 2 is rotatably connected to one side surface of the switchgear body 1 via a hinge chain. A fireproof component 3 is installed inside the switchgear body 1. Suppression components 4 are installed on both sides of the inner sidewall of the switchgear body 1. The fireproof component 3 includes a first partition installed inside the switchgear body 1. A storage tank 301 is installed on the upper surface of the first partition via a support seat. A fireproof pipe 302 is fixedly installed at the output end of the storage tank 301. A solenoid valve 303 is installed on the surface of the fireproof pipe 302. One end of the fireproof pipe 302 is fixedly installed inside the switchgear body 1. Both ends of the fireproof pipe 302 are rotatably connected to connecting pipes. An arc-shaped spray pipe 310 is fixedly installed in a circular array on one side surface of the connecting pipe. A second partition is installed inside the switchgear body 1. A rotating valve is rotatably connected to both sides of the surface of the second partition. The rotating column 304 has pulleys fixedly installed at one end of each of the two rotating columns 304. The outer surfaces of the two pulleys are connected by belts. The lower surface of the first partition is fixedly installed with a drive motor 305 via a clamping plate. The output end of the drive motor 305 is fixedly installed with the rotating column 304. The outer surface of the rotating column 304 is fixedly installed with a first bevel gear 309. The outer surface of the connecting pipe is fixedly installed with a second bevel gear 306. The first bevel gear 309 and the second bevel gear 306 are meshed with each other. The outer surface of the rotating column 304 is rotatably connected with a support member. The support member is fixedly installed on the inner side wall of the switch cabinet body 1. The outer surface of the cabinet door 2 is provided with a controller 307. The lower surface of the second partition is provided with a fire detector 308. The controller 307 is electrically connected to the fire detector 308 and a solenoid valve 303. The solenoid valve 303 is electrically connected to the drive motor 305.

[0026] When the fire detector 308 detects an internal fire, the controller 307 automatically activates the solenoid valve 303 and the drive motor 305. The solenoid valve 303 activates to input carbon dioxide from the storage tank 301 into the fireproof pipe 302. The fireproof pipe 302 inputs carbon dioxide into the connecting pipe and sprays it out through the arc-shaped spray pipe 310. During the spraying process, the drive motor 305 drives the rotating column 304 to rotate. The rotating column 304 drives the other rotating column 304 to rotate synchronously through the pulley. The rotating column 304 drives the first bevel gear 309 at the bottom to rotate. The first bevel gear 309 drives the second bevel gear 306 meshing on one side to rotate. The second bevel gear 306 drives the internal connecting pipe to rotate at one end of the fireproof pipe 302. The connecting pipe drives several arc-shaped spray pipes 310 on one side to rotate, thereby expanding the spray range of the arc-shaped spray pipes 310 and performing all-round fire extinguishing operation, ensuring the safe use of the device.

[0027] A side door 5 is rotatably connected to the side surface of the switch cabinet body 1 via a hinge, and a handle is fixedly installed on the surface of the side door 5.

[0028] By opening the side door 5 with the handle, carbon dioxide can be directly injected into the internal storage tank 301 for future use.

[0029] Several heat dissipation slots 6 are provided on both sides of the switch cabinet body 1. Dustproof nets 7 are provided on the outer surface of the heat dissipation slots 6. The suppression component 4 includes support blocks that are provided on one side of the heat dissipation slots 6. A rotating rod 401 is rotatably connected to the side surface of every two support blocks. A sealing plate 402 is fixedly installed on the outer surface of the rotating rod 401. A driven gear 403 is fixedly installed on the outer surface of the rotating rod 401. A drive gear plate 404 is meshed on one side of the driven gear 403. A vertical rod is connected between several drive gear plates 404. A lifting plate 405 is installed at one end of the bottom vertical rod. An electric push rod 406 is fixedly installed on the lower surface of the lifting plate 405. The electric push rod 406 is fixedly installed on the inner side wall of the switch cabinet body 1.

[0030] Heat is dissipated through the heat dissipation slot 6 and dust is filtered through the dust filter 7. In the initial state, the sealing plate 402 is in a vertical state and will not affect the heat dissipation operation of the heat dissipation slot 6.

[0031] When the fire detector 308 detects an internal fire, it automatically activates the electric push rod 406 to move the lifting plate 405. The lifting plate 405 then moves the upper vertical rods. Through the connection between each vertical rod and the drive gear plate 404, the drive gear plate 404 moves synchronously. The movement of the drive gear plate 404 causes the driven gear 403 to rotate. The driven gear 403 drives the internal rotating rod 401 to rotate on the surface of the support block. The rotating rod 401 drives the outer sealing plate 402 to rotate, causing the sealing plate 402 to rotate 180 degrees. This seals the heat dissipation groove 6, preventing the fire from overflowing through the heat dissipation groove 6 and suppressing the internal flames, thus preventing the fire from spreading.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
