[0028] In a specific embodiment: the flame retardant mechanism 600 includes a sodium azide storage box 601 and a support shell 604 fixedly installed at the bottom of the wind collecting hood 405, and a lighter is provided in the sodium azide storage box 601, and a compressed air bag 602 is installed at the bottom of the sodium azide storage box 601, and the compressed air bag 602 is symmetrically provided with air outlet holes 603.

[0029] It should be noted that the top of the support shell 604 is fixedly connected to the protective box 100, and the side of the support shell 604 is fixedly connected to the side wall of the wind collecting hood 405. A rectangular groove 6041 is provided at the bottom of the support shell 604, and a limiting hole 6042 is provided on the side of the support shell 604 facing the wind collecting hood 405. A sealing door 6043 is installed on the outer wall of the support shell 604, and a limiting plate 605 is provided inside the support shell 604.

[0030] It should be noted that one side of the limiting plate 605 is fixedly connected to a support frame 606, a winding roller 607 is installed in the support frame 606, a fireproof cloth 608 is wound on the winding roller 607, a counterweight block 609 is fixedly connected to the bottom of the fireproof cloth 608, and slide bars 610 are fixedly connected on both sides of the counterweight block 609.

A limiting rod 613 is inserted into the limiting plate 605 , and both ends of the limiting rod 613 are fixedly connected to the support shell 604 .

[0032] The working principle and beneficial effects of the above technical solution are: Working principle: During the use of the present invention, when a fire occurs, the temperature of the space rises, and the lighter in the sodium azide storage box 601 starts to ignite, rapidly burning the sodium azide, generating a large amount of nitrogen that fills the compressed air bag 602, causing the compressed air bag 602 to expand rapidly, thereby blocking the air outlet of the wind collecting cover 405 to prevent the fire from entering the protective box 100, and the nitrogen overflows outward through the air outlet 603 opened at the bottom of the compressed air bag 602. Nitrogen is an inert gas that can effectively perform flame retardant work, and the compressed air bag 602 expands. After expansion, it will push the push plate 611 to move into the support shell 604, and the push plate 611 will push the limit plate 605 to move, thereby driving the support frame 606 to move, so that the winding roller 607 moves to the rectangular groove 6041, and the counterweight block 609 falls downward, driving the fireproof cloth 608 to stretch out, and quickly covering the opening of the protective box 100 to prevent the fire from extending into the equipment, and also to prevent the equipment from catching fire and the fire from spreading outward. By providing a slide rod 610 in conjunction with the limit slot 612, the fireproof cloth 608 has stronger movement stability.

[0033] Beneficial effects: The present invention uses technical means to cooperate with the sodium azide storage box 601 and the compressed air bag 602. By igniting sodium azide, a large amount of nitrogen is generated to fill the compressed air bag 602, so that the volume of the compressed air bag 602 becomes larger and blocks the wind collecting hood 405, preventing the spread of fire and improving safety. By increasing the volume of the compressed air bag 602, the push plate 611 is pushed to move, so that the winding roller 607 moves to the rectangular groove 6041, and the counterweight block 609 drives the fireproof cloth 608 to move downward to block the opening of the protective box 100. At this time, the protective box 100 forms a closed space, and the oxygen content inside is reduced, preventing the fire from spreading further, so that the fire can be effectively controlled.

[0034] In a specific embodiment: a drawer 103 is placed on the bottom surface of the protective box 100, and the drawer 103 is arranged below the partition 101, a control panel 104 is installed on the outer wall of the protective box 100, and a temperature sensor 800 is fixedly installed on the inner wall of the protective box 100.

The fire extinguishing nozzles 703 and the flame retardant nozzles 704 are respectively located above and below the partition 101, and a timing controller is provided on the flame retardant nozzle 704. One end of the fire extinguishing nozzles 703 and the flame retardant nozzles 704 are connected to the interior of the liquid storage tank 701 through pipes.

[0036] The working principle and beneficial effects of the above technical solution are: During use, the present invention monitors the internal temperature of the device in real time through the built-in temperature sensor 800. When the temperature reaches the set ignition point, the fire extinguishing nozzle 703 is controlled to spray the fire retardant liquid in the liquid storage tank 701. When the temperature cannot be effectively controlled, a closed space is formed to isolate the electromechanical equipment from the air and prevent its fire from affecting the safety of other locations underground. In addition, the flame retardant nozzle 704 is used to spray the fire retardant liquid on the fallen ash in the fireproof drawer 103 at regular intervals to prevent the accumulated ash from spontaneous combustion, which is safer. It should be noted that the fire extinguishing nozzle 703 is installed at an upward tilt. During the spraying process, the fire retardant liquid covers the outside of the electromechanical equipment, the spraying angle is larger, and the coverage range is wider. The flame retardant nozzle 704 is installed horizontally, and the horizontal spraying of the fire retardant liquid better covers the inside of the drawer 103.
