[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figure 1 - Figure 6 shown, the embodiment of the present invention provides a fire warning system based on fire fighting relevance, including an electrical cabinet 1, a cabinet door 2 is arranged on the front side of the electrical cabinet 1, a fire extinguishing unit 4 for extinguishing electronic components is arranged inside the electrical cabinet 1, and a warning unit 5 for warning of smoke is arranged on the left side of the electrical cabinet 1.

[0031] The fire extinguishing unit 4 includes a lifting plate 41 which is arranged inside the electrical cabinet 1. Side plates 48 are fixedly connected to both the left and right sides of the lifting plate 41. A chute 410 is formed in the side plate 48. Sliders 411 are slidably connected to the inner sides of the two chutes 410. A top block 412 is fixedly connected to the upper side of the slider 411. Two first fixing blocks 413 are fixedly connected to the upper side of the top block 412. A fixing pipe 414 is fixedly connected between the two first fixing blocks 413. A plurality of nozzles 415 are fixedly connected to the outer side of the fixing pipe 414. A sliding rod 42 is fixedly connected to the inner side of the electrical cabinet 1. A screw rod 43 is rotatably connected to the inner side of the electrical cabinet 1. A smoke sensor 49 is fixedly connected to the outer side of the side plate 48. The screw rod 43 is threadedly connected to the lifting plate 41. The sliding rod 42 is slidably connected to the lifting plate 41. A motor 3 for driving the screw rod 43 is fixedly connected to the upper side of the electrical cabinet 1. A fixing frame 44 is fixedly connected to the left side of the electrical cabinet 1. A carbon dioxide tank 45 is fixedly connected to the inner side of the fixing frame 44. A connecting pipe 416 is fixedly connected between the two fixing pipes 414. An air inlet pipe 46 is fixedly connected between the connecting pipe 416 and the carbon dioxide tank 45. An electromagnetic valve 47 is arranged on the outer side of the air inlet pipe 46.

[0032] When a fire occurs, first, the smoke sensor 49 detects the smoke and, through an external controller, activates the electromagnetic valve 47. Then, the carbon dioxide gas in the carbon dioxide tank 45 enters the connecting pipe 416 through the air inlet pipe 46. Then, the carbon dioxide gas passes through the fixing pipe 414, causing the nozzles 415 on both sides to spray gas onto the electronic devices simultaneously, facilitating the fire extinguishing operation on the electronic devices. At the same time, the motor 3 is started. The motor 3 drives the screw rod 43 to rotate. The screw rod 43 drives the lifting plate 41 to descend. The lifting plate 41 drives the side plate 48 to descend. The side plate 48 drives the nozzles 415 to move up and down, increasing the fire extinguishing range of the nozzles 415 on both sides.

[0033] The outer side of the side plate 48 is fixedly connected with a mounting plate 418, and the lower side of the mounting plate 418 is rotatably connected with a rotating shaft 419. The lower end of the rotating shaft 419 is fixedly connected with a control block 420, and the lower side of the control block 420 is rotatably connected with an inclined plate 1 421, and the inclined plate 1 421 is rotatably connected to the slider 411. The outer side of the rotating shaft 419 is fixedly connected with a bevel gear 1 422, and the outer side of the mounting plate 418 is fixedly connected with a side block 425. The outer side of the side block 425 is rotatably connected with a control rod 424, and one end of the control rod 424 is fixedly connected with a bevel gear 2 423 meshing with the bevel gear 1 422, and the other end of the control rod 424 is fixedly connected with a gear member 426. The inner side of the electrical cabinet 1 is fixedly connected with a toothed plate 417 meshing with the gear member 426. 48 drives the mounting plate 418 to move up and down, and the mounting plate 418 drives the gear member 426 on the control rod 424 to move up and down. Since the gear member 426 is meshed with the tooth plate 417, the gear member 426 rotates, and the gear member 426 drives the control rod 424 to rotate. The control rod 424 drives the bevel gear 2 423 to rotate, and the bevel gear 2 423 drives the bevel gear 1 422 to rotate. The bevel gear 1 422 drives the rotating shaft 419 to rotate, and the rotating shaft 419 drives the control block 420 to rotate. The control block 420 drives the inclined plate 1 421 to rotate, and the inclined plate 1 421 drives the slider 411 to move back and forth repeatedly. The slider 411 drives the top block 412 to move, and the top block 412 drives the nozzle 415 to move back and forth repeatedly, so that the range of the nozzle 415 spraying carbon dioxide gas is increased.
