[0003] The patent with the patent announcement number CN215452085U relates to the technical field of fire prevention for distribution cabinets, and specifically to a distribution cabinet with fire prevention function. The technical problem to be solved by this patent is that during the long-term use of the distribution cabinet, it is inevitable to encounter the situation of overheating, which is prone to dangerous situations such as fire. The existing distribution cabinets have imperfect supporting facilities in terms of fire prevention and poor fire prevention effect. When a fire occurs due to the ineffective fire prevention measures of the existing distribution cabinets, there are no good fire emergency measures to handle the fire, and the fire cannot be extinguished in time, which is very dangerous. To solve the above technical problems, this patent provides a distribution cabinet with fire prevention function. This patent mainly includes a fire prevention structure and a fire extinguishing mechanism, which can detect the temperature inside the distribution cabinet in real time and can automatically control the temperature inside the distribution cabinet to prevent the risk of fire caused by too high temperature. When a fire occurs, it can be discovered in the first time and automatically take measures to extinguish the fire, minimizing the loss and avoiding danger.

[0004] In the above patent, through the fire prevention structure and the fire extinguishing mechanism, the temperature inside the distribution cabinet can be detected in real time and the temperature inside the distribution cabinet can be automatically controlled to prevent the risk of fire caused by too high temperature. When a fire occurs, it can be discovered in the first time and automatically take measures to extinguish the fire, minimizing the loss and avoiding danger. However, in the above patent, when a fire occurs inside the equipment, it may not isolate the outside in time, resulting in the spread of the fire, and the equipment may not be extinguished in time, resulting in equipment damage. Therefore, a distribution cabinet with fire prevention function that can isolate the outside and quickly extinguish the fire when a fire occurs is designed. Summary of the Invention

[0014] The present invention provides a distribution cabinet with a fire prevention function. It has the following beneficial effects: (1) For the distribution cabinet with a fire prevention function, through the coordinated operation among the electric push rod one, the U-shaped plate, the rotating rod, the louvers, the gear, the tooth block, the fire extinguisher, the jet pipe, the blocking valve, the convex block and the filter plate, the louvers rotate to close the square frame, making the interior of the equipment completely closed and not in contact with the outside. Closing the interior of the equipment frame can effectively prevent air from entering, reduce the supply of oxygen, thereby inhibiting the spread of fire, reducing the risk of further fire spread, and reducing the subsequent maintenance cost. At the same time, when the interior of the equipment is closed, the fire extinguishing agent inside the fire extinguisher is sprayed out from the jet pipe to inhibit the fire inside the equipment. Quick extinguishing of the fire can prevent the fire from spreading further, protecting the electrical equipment inside the distribution cabinet from greater damage, thereby reducing equipment losses and maintenance costs.

[0015] (2) The power distribution cabinet with fire prevention function realizes the up and down movement of the circular plate while the scraper scrapes the surface of the circular plate through the coordinated operation among the motor, rotating shaft, circular plate, scraper, convex plate, arc plate, first telescopic elastic rod, arc block, and second telescopic elastic rod. Through the up and down movement, leaves or other sundries can be more effectively peeled off from the surface of the circular plate during the cleaning process, effectively preventing leaves or sundries from assisting combustion and causing the fire to spread in case of a fire. At the same time, the cleaning efficiency is improved. Meanwhile, when moving up and down, knocking on the circular plate can be generated, and the knocking can weaken the adhesion between the leaves and sundries and the circular plate, so that the leaves and sundries can fall off from the surface of the circular plate faster, reducing the workload during cleaning and increasing the cleaning efficiency. Regular knocking and inspection can ensure the normal operation of the equipment, reduce the accident risk, and improve the operation safety.

[0016] (3) The power distribution cabinet with fire prevention function realizes rotation when spraying fire extinguishing agent inside the equipment through the coordinated operation among the fixing plate, bearing plate, extrusion block, fixing block, connecting plate, air inlet cylinder, and bearing block. Rotating the air inlet cylinder can ensure that the fire extinguishing agent is evenly distributed in the entire fire extinguishing area, helping to effectively cover the combustion area, thus improving the fire extinguishing effect. By changing the spraying direction and angle, the fire extinguishing agent can be concentrated on the fire source more quickly, shortening the fire extinguishing time and improving the overall fire extinguishing efficiency. At the same time, when changing the angle, through vibration, the fire extinguishing agent can cover the surface of the burning object faster, reducing the fire intensity and shortening the fire extinguishing time. Vibration can increase the contact time between the fire extinguishing agent and the fire source, making it play a better fire extinguishing effect. Brief Description of the Drawings

Closing the inside of the equipment frame 1 can effectively prevent air from entering and reduce the supply of oxygen, thereby suppressing the spread of fire, reducing the risk of further spread of fire, and reducing subsequent maintenance costs.

[0021] The U-shaped plate 5 slides through the inner and outer walls of the square frame 2, and one end of the U-shaped plate 5 away from the electric push rod 1 4 is set as a beveled surface 1. The output end of the electric push rod 1 4 moves upward to drive the U-shaped plate 5 to move upward.

[0022] The gear 8 meshes with the tooth block 9. One side of the convex block 13 away from the blocking valve 12 is set as the first arc surface. When the tooth block 9 moves upward to contact and squeeze the gear 8 to rotate, the convex block 13 moves to release the limit on the blocking valve 12.

[0023] During the operation of this embodiment: When a fire occurs inside the equipment, the electric push rod 1 4 is started. The output end of the electric push rod 1 4 moves upward to drive the U-shaped plate 5 to move upward. The upward movement of the U-shaped plate 5 drives the tooth block 9 to move upward.

The movement of the convex block 13 releases the limit of the blocking valve 12 on the spray pipe 11. After the limit of the spray pipe 11 is released, the fire extinguishing agent inside the fire extinguisher 10 can be sprayed out through the spray pipe 11 to inhibit the fire inside the equipment. Quick extinguishing of the fire can prevent the fire from spreading further, protect the electrical equipment inside the power distribution cabinet from greater damage, thereby reducing equipment losses and maintenance costs. Timely extinguishing of the fire can reduce the severity of the consequences of the fire, thereby reducing subsequent cleaning and maintenance work, saving time and costs.

[0024] Please refer to Figures 1-8 , on the basis of the above embodiment, another embodiment of the present invention further includes a cleaning device and a rotating device; the cleaning device includes a motor 151, a rotating shaft 152, a circular plate 153, a scraping plate 154, a convex plate 155, an arc plate 157 and an arc block 158. The motor 151 is fixedly installed on the inner wall of the top of the equipment frame 1. The rotating shaft 152 is fixedly installed at the output end of the motor 151. The circular plate 153 is sleeved on the circumferential surface of the rotating shaft 152. The scraping plate 154 is fixedly installed on the circumferential surface of the rotating shaft 152. The convex plate 155 is fixedly installed above the circular plate 153. A sliding groove 101 is opened on the surface of the equipment frame 1. The arc plate 157 is slidably installed inside the sliding groove 101. The arc block 158 is fixedly installed below the circular plate 153, realizing that while the scraping plate 154 scrapes the surface of the circular plate 153, the circular plate 153 can move up and down. Through the up and down movement, leaves and sundries can be more effectively peeled off from the surface of the circular plate 153 during the cleaning process, effectively preventing leaves or sundries from assisting combustion and causing the spread of the fire during a fire, and at the same time improving the cleaning efficiency.

[0025] Above the convex plate 155 is set as convex surface two. A telescopic spring rod one 156 is fixedly installed above the equipment frame 1. The free end of the telescopic spring rod one 156 is fixedly connected to the lower part of the circular plate 153. When the convex plate 155 moves downward, it drives the circular plate 153 to move downward. When the circular plate 153 moves downward, it contacts and presses the telescopic end of the telescopic spring rod one 156 to contract.

[0026] The rotating shaft 152 fixedly penetrates the inner and outer walls of the equipment frame 1. A telescopic spring rod two 159 is fixedly installed inside the sliding groove 101. The free end of the telescopic spring rod two 159 is fixedly connected to the arc plate 157. When the arc plate 157 moves downward, it contacts and presses the telescopic end of the telescopic spring rod two 159 to contract.

[0027] The rotating device includes a fixed plate 161, a bearing plate 162, a pressing block 163, a fixed block 164, a connecting plate 165, an air inlet cylinder 166 and a bearing block 167. The fixed plate 161 is fixedly installed below the circular plate 153. The bearing plate 162 is fixedly installed at the top of the inner wall of the equipment frame 1. The pressing block 163 is fixedly installed at one end of the fixed plate 161 close to the bearing plate 162. The fixed block 164 is fixedly installed at one end of the bearing plate 162 close to the fixed plate 161. The connecting plate 165 is hinged inside one end of the fixed plate 161 away from the circular plate 153. The air inlet cylinder 166 is rotatably installed on the circumferential surface of the spray pipe 11. The bearing block 167 is fixedly installed on the circumferential surface of the air inlet cylinder 166. By rotating the air inlet cylinder 166, it realizes rotation when spraying fire extinguishing agent inside the equipment. Rotating the air inlet cylinder 166 can ensure that the fire extinguishing agent is evenly distributed throughout the fire extinguishing area, which helps to effectively cover the combustion area, thereby improving the fire extinguishing effect. By changing the spraying direction and angle, the fire extinguishing agent can be concentrated on the fire source more quickly, shortening the fire extinguishing time and improving the overall fire extinguishing efficiency.

[0028] The fixed plate 161 slidably penetrates the inner and outer walls of the equipment frame 1. One side of the pressing block 163 close to the bearing plate 162 is set as convex surface three. One side of the fixed block 164 close to the fixed plate 161 is set as convex surface four. The connecting plate 165 is hinged to the inside of the end of the bearing block 167 away from the air inlet cylinder 166. The surface of the air inlet cylinder 166 is provided with air jet ports. When the fixed plate 161 moves downward, it drives the pressing block 163 to move downward. When the pressing block 163 moves downward, it contacts and presses the fixed block 164.

[0029] Start the motor 151. The rotation of the output end of the motor 151 drives the rotation of the scraper 154. The rotation of the scraper 154 contacts and squeezes the convex plate 155 to move downward. The downward movement of the convex plate 155 drives the circular plate 153 to move downward. The downward movement of the circular plate 153 contacts and squeezes the telescopic end of the first telescopic spring rod 156 to contract, and then reset, realizing that while the scraper 154 scrapes the surface of the circular plate 153, the circular plate 153 can move up and down. Through the up and down movement, during the cleaning process, the leaves and sundries can be more effectively peeled off from the surface of the circular plate 153, effectively preventing the leaves or sundries from assisting combustion and causing the fire to spread when a fire occurs, and at the same time improving the cleaning efficiency. When the circular plate 153 moves downward, it drives the arc block 158 to move downward. The downward movement of the arc block 158 contacts and squeezes the arc plate 157 to move downward. The downward movement of the arc plate 157 contacts and squeezes the telescopic end of the second telescopic spring rod 159 to contract, and then reset, thus generating a knock on the circular plate 153. The knock can weaken the adhesion between the leaves and sundries and the circular plate 153, so that the leaves and sundries can fall off from the surface of the circular plate 153 faster, reducing the workload during cleaning, increasing the cleaning efficiency. Regular knocking and inspection can ensure the normal operation of the equipment, reduce the accident risk, and improve the operation safety.

[0030] When a fire breaks out inside, when the fire extinguisher 10 sprays the fire extinguishing agent through the spray pipe 11 for fire extinguishing, when the circular plate 153 moves downward, it drives the fixing plate 161 to move downward. The downward movement of the fixing plate 161 drives the connecting plate 165 to rotate. The rotation of the connecting plate 165 drives the receiving block 167 to rotate. The rotation of the receiving block 167 drives the air intake cylinder 166 to rotate. The rotation of the air intake cylinder 166 drives the rotation of the jet orifice on its surface, and sprays the fire extinguishing agent inside the fire extinguisher 10 to the air intake cylinder 166 through the spray pipe 11, and sprays the gas to the inside of the equipment through the jet orifice on the surface of the air intake cylinder 166. At the same time, through the rotation of the air intake cylinder 166, it realizes the rotation when spraying the fire extinguishing agent inside the equipment. Rotating the air intake cylinder 166 can ensure that the fire extinguishing agent is evenly distributed in the entire fire extinguishing area, helping to effectively cover the combustion area, thereby improving the fire extinguishing effect. By changing the spraying direction and angle, the fire extinguishing agent can be concentrated on the fire source more quickly, shortening the fire extinguishing time and improving the overall fire extinguishing efficiency. When the fixing plate 161 moves downward, it drives the extrusion block 163 to move downward. The downward movement of the extrusion block 163 contacts and squeezes the fixed block 164, thereby generating vibration. The vibration can make the fire extinguishing agent contact the air intake cylinder 166 more evenly, making the fire extinguishing agent contact the air intake cylinder 166 more. At the same time, through the vibration, the fire extinguishing agent can cover the surface of the burning object faster, reducing the fire, shortening the fire extinguishing time. The vibration can increase the contact time between the fire extinguishing agent and the fire source, making it play a better fire extinguishing effect.
