The cabinets not only provide physical space protection for these devices but also ensure the stability and security of device operation.

[0003] The cabinet is a freestanding enclosure widely used to house electrical or electronic equipment. Some of the equipment inside the cabinet has a high temperature and a large heat output. If the heat dissipation ability is weak or the heat dissipation equipment fails, it may cause a fire. When the existing technology is in use, most of them use the spraying method to prevent the spread of fire, which may damage the equipment inside the cabinet. Therefore, we propose a fire prevention device for network computer room cabinets to solve the problems raised above. Content of the Utility Model

[0024] The effect achieved by the entire Embodiment 1 is that when the electric push rod 112 extends or retracts subsequently, it will drive the bracket 111, the servo motor 108, the nozzle 115 and the flexible hose 114 to move up and down together, so as to adjust the height of the nozzle 115, so that subsequent adjustments can be made according to requirements. Through the cooperation of the servo motor 108 and the rotating shaft 116, the angle of the nozzle 115 can be adjusted, and as Figure 3 shown, slots are provided on both sides of the inner bottom of the box 109, and the flexible hose 114 is located inside it to ensure that the flexible hose 114 can swing normally and avoid interference, as Figure 1and Figure 3 As shown, a connecting pipe and a solenoid valve are provided on one side of the gas storage tank 106, and a release valve is provided on the telescopic hose 114.

[0025] Example 2, as Figures 1 - 4 As shown, a baffle 103 is hinged to the front outer surface of the cabinet body 101. Heat dissipation plates 102 are fixedly connected to the outer surfaces of both sides of the cabinet body 101 near the bottom. Heat dissipation holes 104 are formed in the positions of both sides of the front and rear outer surfaces of the box body 109. A filter screen 105 is fixedly connected to the center of the inner wall of the heat dissipation hole 104. The rear outer surface of the nozzle 115 is rotatably connected to the rear inner surface of the bracket 111. One end of the rotating shaft 116 penetrates through the surface of the bracket 111 and is fixedly connected to the output end of the servo motor 108. The other end of the rotating shaft 116 is fixedly connected to the front outer surface of the nozzle 115. A telescopic hose 114 is disposed through the center of the bottom of the gas storage tank 106. The inside of the telescopic hose 114 is communicated with the inside of the nozzle 115. A PLC controller 113 is fixedly installed at the center of the inner bottom of the box body 109. Smoke detectors 107 are fixedly installed at the positions near the top of the inner surfaces of both sides of the cabinet body 101. Sliders 110 are slidably connected to the front and rear positions of the inner surfaces of both sides of the box body 109. The outer surface of the slider 110 is fixedly connected to the outer surface of the bracket 111. The moving structure 2 includes a connecting rod 201. A self-locking wheel 202 is fixedly installed at the bottom end surface of the connecting rod 201. The top end surface of the connecting rod 201 is fixedly connected to the bottom surface of the cabinet body 101.

[0026] The effect achieved by the entire Example 2 is that through the setting of the filter screen 105, the function of filtering dust can be realized. During actual use, the PLC controller 113 is electrically connected to multiple components so as to control the opening and closing of multiple components. Through the setting of the slider 110, the stability of the bracket 111 during up and down movement can be improved. Through the cooperation of the connecting rod 201 and the self-locking wheel 202, it is convenient for the user to carry the whole.

[0027] Working principle: During actual use, when the smoke detector 107 detects a fire signal, the PLC controller 113 will issue a start command, causing the electric push rod 112 to extend or retract, so that the heights of the bracket 111 and the sprinkler head 115 can be adjusted. After the adjustment, the PLC controller 113 controls the release valve on the telescopic hose 114. Then, the carbon dioxide in the gas storage tank 106 is transported through the telescopic hose 114 and finally can be transported to the sprinkler head 115 and sprayed out through the sprinkler head 115. It is sprayed towards the area where fire extinguishing is required. Since its density is greater than that of air, the released carbon dioxide will settle to the lower part, diluting the oxygen concentration and making the combustion area lack oxygen, thus achieving the effect of extinguishing fire by asphyxiation. At the same time as spraying, the servo motor 108 can operate together, enabling the rotating shaft 116 to rotate. When the rotating shaft 116 can rotate, it will drive the sprinkler head 115 to swing left and right, thereby enabling the position of the sprinkler head 115 to be adjusted so as to correspond to fire areas in different positions.
