[0003] Existing anti-theft distribution cabinets are often placed inside the distribution cabinet, and the door of the distribution cabinet is closed and locked with a metal lock to prevent people from easily opening the distribution cabinet and stealing. However, when thieves with certain lock-picking skills use this type of distribution cabinet to steal, the protection ability of the general metal lock on the distribution cabinet will be greatly reduced. At the same time, when the current high-voltage distribution cabinet is in use, it is usually used to blow air to dissipate heat from the internal electrical components using heat dissipation holes and fans. During the heat dissipation process, the air is not evenly blown, and some electrical components cannot obtain sufficient heat dissipation effect. At the same time, during the heat dissipation process, some dust and moisture are mixed in the air and blown onto the electrical components, causing damage to the electrical components. At the same time, when a fire occurs in the electrical components in the distribution cabinet, the internal fire cannot be extinguished in time, causing all the internal electrical components to burn, resulting in a large loss.

A transmission shaft 53 is rotatably connected in the ventilation pipe 51. A fan blade 54 is fixedly sleeved on the outer surface of the transmission shaft 53. A cleaning plate 55 slidably connected to the filter screen plate 52 is fixedly sleeved on the outer surface of the transmission shaft 53. One end of the second transmission pipe 35 is fixedly connected to a drying mechanism connected to the distribution cabinet body 2. The drying mechanism is used to dry the air. An outlet pipe 37 is fixedly connected to the top of the distribution cabinet body 2, and an electromagnetic valve is arranged on the outlet pipe 37.

[0027] The air inlet pipe 32 is provided with a fire extinguishing mechanism connected to the power distribution cabinet body 2 , and the fire extinguishing mechanism is used to extinguish the fire in the power distribution cabinet body 2 in time.

[0028] By starting the fan 36, the fan 36 sucks air from the ventilation pipe 51 through the pipeline, and then filters impurities in the air through the filter screen 52 on the ventilation pipe 51. At the same time, the wind flows from the ventilation pipe 51 to drive the fan blades 54 to rotate, and the fan blades 54 drive the transmission shaft 53 to rotate, and the transmission shaft 53 drives the cleaning plate 55 to rotate. The cleaning plate 55 cleans the filter screen 52 to achieve self-cleaning of the filter screen 52 and filter the air to achieve dust-free air supply.

[0030] When the humidity sensor on the distribution box body 1 detects that the humidity in the air is high, the electromagnetic valve on the first transmission pipe 34 is closed, and the electromagnetic valve on the third transmission pipe 44 is opened. Then the fan 36 passes the air into the transparent drying box 41 through the first transmission pipe 34. Then the silica gel desiccant in the transparent drying box 41 absorbs and dries the moisture in the air. Then the dry gas enters the air inlet pipe 32 through the third transmission pipe 44, so that the dry gas is supplied to the air inlet pipe 32, reducing the damage of moisture to the electrical components in the distribution cabinet during heat dissipation, achieving the moisture-proof effect in the distribution cabinet body 2, and further improving the service life of the components. When the air humidity is reduced, the electromagnetic valve on the third transmission pipe 44 is closed, and the electromagnetic valve on the first transmission pipe 34 is opened for normal heat dissipation. At this time, when the humidity sensor in the transparent drying box 41 detects that the humidity of the silica gel desiccant is high, the electric heating plate 42 is started, and the electric heating plate 42 heats the silica gel, so that the moisture is discharged through the one-way valve on the exhaust pipe 43, so as to realize the reuse of the silica gel desiccant.

[0031] Embodiment 4 Based on Example 2, please refer to Figure 2 , Figure 4 , Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, the fire extinguishing mechanism includes a first gas box 61 fixedly connected to the power distribution cabinet body 2, a push plate 62 is slidably connected in the first gas box 61, a spring 63 fixedly connected to the first gas box 61 is fixedly connected on one side of the push plate 62, a contact switch 64 is fixedly connected in the first gas box 61, the contact switch 64 is electrically connected to the electromagnetic valve on the outlet pipe 37, a first inflation pipe 65 is fixedly connected to one side of the first gas box 61, a one-way valve is arranged on the first inflation pipe 65, and a first gas box 61 is fixedly connected to one side through a pipeline.

[0032] The carbon dioxide gas is introduced into the first gas box 61 through the cooperation of the first inflation tube 65 and the one-way valve on the first inflation tube 65, and then the gas pushes the push plate 62 in the first gas box 61, driving the push plate 62 to move. At this time, the spring 63 is stretched, and at the same time, the first gas box 61 introduces gas into the film tube 67 through the installation tube 66, so that the film tube 67 bulges. At the same time, when the electrical components are installed, the bulged film tube 67 is attached to various parts of the components. When a component in the distribution cabinet body 2 is damaged and a fire occurs, the film tube 67 at this position is melted by heat and leaks. At this time, the carbon dioxide gas is blown out at the position of the film tube 67 under the action of air pressure, and carbon dioxide is blown into the fire point in time to extinguish the fire, thereby reducing the risk of fire. The low fire damages other components, and the gas in the first air box 61 leaks. At this time, the push plate 62 begins to contact the contact switch 64 under the tension of the spring 63. At this time, the contact switch 64 promptly closes the electromagnetic valves on the air inlet pipe 32 and the air outlet pipe 37, and opens the electromagnetic valve on the fourth transmission pipe 69 on the second air box 68. Then the carbon dioxide gas in the second air box 68 enters the anti-theft pipe 18 through the air inlet pipe 32, and then is discharged through the air outlet 38 on the anti-theft pipe 18. The carbon dioxide gas is evenly filled into the main body 2 of the distribution cabinet to extinguish the fire and prevent the further spread of the fire, thereby realizing timely and accurate fire extinguishing when a fire occurs in the high-voltage distribution cabinet, greatly improving the protection of electrical components in the distribution cabinet.

[0033] The working principle of the present invention is as follows: after the components in the power distribution cabinet body 2 are installed and fixed, the anti-theft plate 11 is then inserted into the mounting ring plate 3, and then the driving motor 21 drives the driving shaft 22 to rotate, and the driving shaft 22 drives the threaded rod 28 to rotate through the first bevel gear 23 and the second bevel gear 24, and the threaded rod 28 drives the connecting plate 25 to move, and the connecting plate 25 drives the transmission rod 13 to move, and the transmission rod 13 drives the transmission plate 14 to move, and the transmission plate 14 drives a plurality of fixing columns 15 to be inserted into the fixing groove 16 on the mounting ring plate 3, and at the same time, the threaded rod 28 is self-locking, so that the fixing column 15 is stably inserted into the fixing groove 16, so as to achieve stable fixing of the anti-theft plate 11 It is fixed on the mounting ring plate 3, and an operating groove 17 is provided on the anti-theft plate 11 and an anti-theft tube 18 is fixedly connected in the operating groove 17. When it is necessary to open and close the components normally, an ordinary electrician only needs to open the key on the protective door 4. When it is necessary to repair or move the components in the distribution cabinet, a person with a higher position is required to perform facial recognition or enter a password to start the drive motor 21. The drive motor 21 drives the drive shaft 22 to rotate in the opposite direction, so that the fixed column 15 is moved out of the fixed groove 16, and the anti-theft plate 11 is disassembled, thereby realizing safe anti-theft without affecting the use of the components in the distribution cabinet, and further improving the applicability of the distribution cabinet.
