[0028] like Figures 1 to 6As shown, a high and low voltage cabinet protection device includes: a fixed box 1, which is open on one side, and a connecting hole 104 is opened inside the fixed box 1. A fan 101 and a guide 103 are respectively provided inside the fixed box 1, and the guide 103 is located just above the connecting hole 104; a protection mechanism is arranged outside the fixed box 1 and is used to replace the gas inside the fixed box 1. The protection mechanism includes a guide component 2, a control component 4 and a gas cylinder 3. The gas cylinder 3 is arranged outside the fixed box 1 and is used to add gas to the fixed box 1. The guide component 2 is arranged outside the fixed box 1 and is used to guide the gas. The control component 4 is arranged inside the guide component 2 and is used to replace the gas inside the fixed box 1. The gas is blocked, and the guide component 2 cooperates with the control component 4 to control the gas entering the fixed box 1. Specifically, during the use of the fixed box 1, air enters the guide component 2 under the action of the fan 101, thereby cooling the equipment inside the fixed box 1 and ensuring the temperature stability of the equipment inside the fixed box 1 during use. When a fire occurs inside the fixed box 1, the control component 4 is used to block the external air to prevent the oxygen in the air from entering the fixed box 1 through the guide component 2. While blocking the air, the gas inside the gas cylinder 3 enters the fixed box 1 through the guide component 2, thereby removing the remaining oxygen inside the fixed box 1. The fan 101 is used to drive the gas to flow inside the fixed box 1, thereby cooling the electrical appliances installed inside the fixed box 1 and quickly filling the gas inside the gas cylinder 3 into the fixed box 1 when a fire occurs. An electronic thermometer and a smoke sensor are also provided inside the fan 101. The electronic thermometer can detect the temperature discharged from the fixed box 1 during use, so that the fire can be quickly detected in cooperation with the smoke sensor. A control module is also installed inside the fixed box 1. During use, the control module can identify the signals detected by the electronic thermometer and the smoke sensor. When a fire is detected, the control module controls the control component 4 and the gas cylinder 3 to extinguish the flame inside the fixed box 1. The control module is pre-set with thresholds for smoke concentration and temperature. The control module is a prior art and will not be explained in detail here. During use, the gas enters the fixed box 1 through the connecting hole 104. In the process of the gas entering the fixed box 1, the flow direction of the gas is guided by the guide 103, so that the gas can flow evenly inside the fixed box 1.

[0029] like Figures 1 to 6 As shown, a fixing shell 102 is further provided on the outside of the fixing box 1, and a fixing frame is provided inside the fixing shell 102. Specifically, the fixing shell 102 cooperates with the fixing frame to fix and protect the gas cylinder 3 during use, ensuring the stability of the gas cylinder 3 during use.

[0030] like Figures 1 to 6 As shown, the gas cylinder 3 is arranged on the outside of the fixed frame, and the gas outlet end of the gas cylinder 3 is sequentially provided with a control valve and a connecting pipe 302. Specifically, the gas cylinder 3 is a container that can store compressed gas. The number of gas cylinders 3 can be selected according to the size of the fixed box 1 to ensure that the gas inside the gas cylinder 3 can be fully filled into the fixed box 1. The gas outlet end of the gas cylinder 3 is provided with an electronic control valve, which is connected to the control module through a wire. The gas space inside the gas cylinder 3 is guided into the fixed box 1 through the connecting pipe 302.

[0031] like Figures 1 to 6 As shown, the guide assembly 2 includes a fixed block 201, a mounting block 206 and a bottom plate 203. The fixed block 201 is arranged at the bottom of the fixed box 1. An air outlet 202 is provided inside the fixed block 201, and the air outlet 202 is communicated with the connecting pipe 302. The mounting block 206 and the bottom plate 203 are sequentially arranged on the outside of the fixed block 201. The bottom plate 203 is provided with a groove 204 on one side relative to the mounting block 206. A through hole 205 is provided inside the fixed block 201. The through hole 205 passes through the fixed block 201, the mounting block 206 and the bottom plate 203, and the through hole 205 is respectively communicated with the air outlet 202 and the groove 204. Specifically, during use, air is first introduced into the fixed box 1 through the through hole 205, so that the electrical appliances inside the fixed box 1 are cooled during use. When a fire occurs inside the fixed box 1, the control module cooperates with the control assembly 4 to control the fire. The air inlet end of the through hole 205 is sealed to prevent oxygen from continuing to enter the fixed box 1 through the through hole 205. While the through hole 205 is sealed, the gas inside the gas cylinder 3 enters the fixed box 1 through the cooperation of the air outlet 202 and the through hole 205, thereby reducing the oxygen concentration inside the fixed box 1 and preventing the fire source from continuing to burn. A support frame is provided at the bottom of the bottom plate 203, which separates the bottom plate 203 from the ground, ensuring that air can enter the fixed box 1 through the through hole 205 during use. The fixing block 201, the mounting block 206 and the bottom plate 203 are connected by bolts or snaps, which facilitates the disassembly and maintenance of the fixing block 201, the mounting block 206 and the bottom plate 203 during use. A filter is provided at the bottom of the bottom plate 203 to filter the air entering the through hole 205 during use to prevent dust from entering the fixed box 1 with the air.

[0032] like Figures 1 to 6As shown, the control assembly 4 includes a fixed shaft 404 and a control member 406, both of which are connected to the mounting block 206. A control plate 401 and a first gear 402 are provided on the outside of the fixed shaft 404. The control plate 401 slides inside the groove 204. There are multiple first gears 402. A rack 403 is engaged with the outside of the first gear 402, and the rack 403 slides inside the mounting block 206. The control member 406 is connected to the rack 403. Specifically, when the through hole 205 needs to be closed, the rack 403 is driven to move by the control member 406. When the control member 406 moves, the fixed shaft 404 is driven to rotate by the first gear 402. The rotating fixed shaft 404 drives the control plate 401 to move, thereby closing the through hole 205. The control plate 401 fits with the groove 204 to prevent air from penetrating through the gap between the control plate 401 and the groove 204 when the control plate 401 seals the through hole 205. The number of first gears 402 can be selected according to usage requirements to avoid interference when the rack 403 drives the first gear 402. The control member 406 can be a threaded rod or an electric telescopic rod.

[0033] like Figures 1 to 6 As shown, a spring 405 is further provided on the outside of the rack 403, and the spring 405 is sleeved on the outside of the control member 406. Specifically, the spring 405 provides support for the rack 403 when in use, ensuring the stability of the position of the rack 403 when in use.
