Technical Field

[0002] A distribution box is a box used to distribute electricity. It is like a "fork in the road" for electricity, which can send electricity to different places, just like a water pipe is divided into many branches, each branch can send water to different places. The distribution box has switches that can control the flow of current. The protection structure of the distribution box is a multi-faceted design designed to ensure the reliability, safety, and adaptability of the equipment to the external environment. Different types of distribution boxes may have different protection characteristics.
[0003] If the heat dissipation effect of the distribution box is not good, or if the circuit is short-circuited and a large amount of heat is generated due to factors such as humidity, the terminal blocks, wires and other electrical equipment may accidentally catch fire under high temperatures, which will not only seriously damage the equipment, but may also cause a larger range of fires, causing immeasurable economic losses and safety hazards. In response to the above problems, the following solutions are proposed. Summary of the invention
[0004] In order to solve the above technical problems, the present invention provides a distribution box protection structure, including a piercing assembly, the piercing assembly includes a shell, a box door is arranged on the front of the shell, and an air storage bag is fixedly connected to the top of the inner wall of the shell;
[0005] The sealing assembly includes a limit rod arranged inside the housing, a sliding plate is slidably connected to the outer surface of the limit rod, and a spring 2 is fixedly connected to the bottom of the sliding plate;
[0006] The auxiliary component includes two support plates fixedly connected to the back of the inner wall of the outer shell, the top of the support plate is fixedly connected to the air storage shell, and the inner wall of the air storage shell is slidably connected to the lifting rod.
[0007] Preferably, two fixed plates 1 are fixedly connected to the top of the inner wall of the shell, a fixed rod is fixedly connected to the bottom of the fixed plate 1, a fixed plate 2 is fixedly connected to the bottom of the fixed rod, two sliding rods 1 are slidably connected to the inner wall of the fixed plate 1, and the outer surface of the sliding rod 1 is slidably connected to the inner wall of the fixed plate 2.
[0008] Preferably, the outer surfaces of the fixed rod and the two sliding rods are respectively slidably connected with three puncture plates, the bottom of the puncture plate is fixedly connected with a spring, the bottom of the spring is fixedly connected to the outer wall of the sliding rod, the bottom of the puncture plate is fixedly connected with a connecting frame, the bottom of the connecting frame contacts with a magnet, and the back of the magnet is fixedly connected to the back of the inner wall of the shell. When the temperature at the position where any of the magnets is located rises abnormally, the magnetism of the magnet will gradually decrease due to the influence of the high temperature. When the temperature at that place reaches a dangerous level, the magnetism of the magnet has been reduced to the point that it can no longer adsorb the connecting frame. At this time, the connecting frame and the puncture plate as a whole will be on the spring. It moves upward under the action of spring one. It should be noted that spring one is already in a compressed state when installed. When the puncture plate moves upward, it will drive the spike fixed on its top to move upward together. When the spike contacts the air storage bag, the air storage bag will be punctured. At this time, the compressed inert gas in the air storage bag will be discharged and then fill the inside of the shell to prevent open flames. This design can prevent the distribution box from abnormally increasing the temperature in local locations due to factors such as humidity, thereby generating open flames and causing greater economic losses and safety hazards by automatically monitoring and responding to high temperature conditions.
[0009] Preferably, the top and bottom of the limit rod are respectively fixedly connected to the bottom of the fixed plate 1 and the top of the fixed plate 2 near the back, the bottom of the spring 2 is fixedly connected to the top of the fixed plate 2 near the back, the bottom of the sliding plate is fixedly connected with a joint 1, the back of the fixed plate 2 near the back is fixedly connected with a joint 2, the top of the sliding plate is fixedly connected with a joint 3, and the back of the fixed plate 1 near the back is fixedly connected with a joint 4. When any puncture plate moves upward, it will drive the sliding plate 1 to move upward and stretch the spring 2. When the sliding plate moves upward, it will drive the joint 1 to move upward. When the joint 1 moves to separate from the joint 2, the total circuit of the device will be disconnected, thereby preventing the device from continuing to work and causing the temperature to continue to rise.
[0010] Preferably, the bottom of the fixed plate second near the back is fixedly connected with an electric telescopic rod, the bottom of the output end of the electric telescopic rod is fixedly connected with a moving plate, the top of the moving plate is fixedly connected with a pressure rod, the outer surface of the pressure rod is slidably connected with a sealing plate, the top of the sealing plate is fixedly connected with a spring three, the top of the spring three is fixedly connected to the outer wall of the pressure rod, and the sliding plate will also drive the joint three to move upward when it moves upward. When the joint three moves to contact with the joint four, the electric telescopic rod will form a passage with a power supply separately provided for it, and the electric telescopic rod will push the moving plate to move downward after it is started. During the downward movement of the moving plate, the sealing plate will drive the sealing plate to move downward through the spring three, and then the ventilating opening of the shell will be sealed through the sealing plate. When the moving plate needs to continue to move downward, the pressure rod will compress the spring three to continue to move downward. This design can disconnect the main power supply when the temperature of the device is abnormal to prevent the temperature from continuing to rise, and the device can also be sealed through the sealing plate to prevent the inert gas from being exchanged with the external air, resulting in the conditions for generating open flames inside the shell.
[0011] The jacking plate is slidably connected to the inner wall of the gas storage shell, and the lifting plate is connected to the lifting plate at one end and the lifting plate is connected to the lifting plate at the other end. The movable pressure plate moves downward together, and the pressure plate will squeeze the air inside the air storage shell during the downward movement, and push the air into the air guide hose, and the air guide hose will pass the air into the air guide cavity, and the air guide cavity will pass the air into the fixed sleeve one, and the air passed into the fixed sleeve one will push the sliding rod two in the direction close to the puncture plate and compress the spring four, and the sliding rod two will drive the moving inclined block one to move during the movement, and the moving inclined block will squeeze the lifting plate during the movement, so that the lifting plate moves upward along the inclined surface of the moving inclined block, and in the process of the lifting plate moving upward, the puncture plate that has not moved upward will be driven to move upward to pierce the air storage airbag. This design can drive the puncture plate that has not risen to move upward, and can prevent the puncture plate that rises alone in the puncture assembly from accidentally failing to pierce the air storage airbag, resulting in the inert gas being unable to be discharged smoothly.
[0012] Preferably, the inner wall of the lifting plate is slidably connected to the outer wall of the puncture plate slidably connected to the sliding rod 1, the outer wall of the air guide hose is fixedly connected with a soft branch tube, the soft branch tube is fixedly connected with a fixed sleeve 2 at one end away from the air guide hose, the bottom of the fixed sleeve 2 is fixedly connected to the top of the support plate, the inner wall of the fixed sleeve 2 is slidably connected with a sliding bent rod, the sliding bent rod is fixedly connected with a spring 5 at a side away from the puncture plate, the spring 5 is fixedly connected to the inner wall of the fixed sleeve 2 at one end away from the sliding bent rod, the outer surface of the sliding bent rod is slidably connected to the corresponding inner wall of the puncture plate, the air introduced into the air guide hose will also enter the soft branch tube, and since the elastic force of the spring 5 is greater than the elastic force of the spring 4, the air will first push the sliding rod 2 to compress Spring four, when the sliding rod two moves to the final position, as the pressure plate continues to push the air into the air guide hose, the air will enter the fixed sleeve two through the soft branch tube, and the air entering the fixed sleeve two will push the sliding bent rod in the direction away from the puncture plate and compress the spring five, and the sliding bent rod will drive the puncture plate to move together during the movement, and the puncture plate will pull the air storage airbag through the spikes that pierce the air storage airbag during the movement, so that the damaged opening of the air storage airbag is enlarged. This design can prevent the air storage airbag from rupturing after the puncture plate pierces the air storage airbag, resulting in the spikes remaining in the air storage airbag to block the damaged opening, so that the inert gas cannot be discharged quickly.
[0013] A protection method for a distribution box protection structure includes the following steps:
[0014] S1: When the temperature at the location of any magnet rises abnormally, the connecting frame and the puncture plate will move upward as a whole under the action of spring 1, and then puncture the air storage bag, and the compressed inert gas in the air storage bag will be discharged;
[0015] S2: When any puncture plate moves upward, it will drive the sliding plate to move upward, the main circuit of the device will be disconnected, the electric telescopic rod will start, and then drive the sealing plate to seal the vent of the shell;
[0016] S3: When the movable plate moves downward, the pressing plate pushes air into the air hose, thereby pushing the inclined block to move, and lifting all the puncture plates upward. The air entering the air hose also enters the soft branch pipe, thereby driving the puncture plates to move.
[0017] The present invention has the following beneficial effects:
[0018] 1. In the present invention, when the temperature at any position of the magnet increases abnormally, the magnetism of the magnet will gradually decrease due to the influence of high temperature. When the temperature at that position reaches a dangerous level, the magnetism of the magnet has been reduced to the point where it can no longer adsorb the connecting frame. At this time, the connecting frame and the piercing plate as a whole will move upward under the action of spring 1. It should be noted that spring 1 is already in a compressed state during installation. When the piercing plate moves upward, it will drive the spike fixed on its top to move upward together. When the spike contacts the air storage bag, the air storage bag will be punctured. At this time, the compressed inert gas in the air storage bag will be discharged and then fill the inside of the shell to prevent the generation of open flames. This design can prevent the distribution box from abnormally increasing the temperature at a local position due to factors such as humidity, thereby generating open flames and causing greater economic losses and safety hazards by automatically monitoring and responding to high temperature conditions.
[0019] 2. In the process of upward movement of any puncture plate of the present invention, the sliding plate will drive the sliding plate 1 to move upward and stretch the spring 2. In the process of upward movement of the sliding plate, the joint 1 will be driven to move upward together. When the joint 1 moves to separate from the joint 2, the total circuit of the device will be disconnected, thereby preventing the device from continuing to work and causing the temperature to continue to rise. When the sliding plate moves upward, it will also drive the joint 3 to move upward. When the joint 3 moves to contact with the joint 4, the electric telescopic rod will form a passage with the power supply separately provided for it. After the electric telescopic rod is started, it will push the moving plate to move downward. In the process of downward movement of the moving plate, the sealing plate will be driven downward by the spring 3, and then the vent of the shell will be sealed by the sealing plate. When the moving plate needs to continue to move downward, the pressure rod will compress the spring 3 to continue to move downward. This design can disconnect the total power supply when the temperature of the device is abnormal to prevent the temperature from continuing to rise. The device can also be sealed by the sealing plate to prevent the inert gas from being exchanged with the external air, resulting in the conditions for generating open flames inside the shell.
[0020] The air in the air bag is pushed into the air guide tube, and the air guide tube passes the air into the air guide cavity, and the air guide cavity passes the air into the fixed sleeve 1. The air passed into the fixed sleeve 1 will push the sliding rod 2 in the direction close to the puncture plate and compress the spring 4. The sliding rod 2 will drive the moving inclined block 1 to move together during the movement, and the moving inclined block will squeeze the lifting plate during the movement, so that the lifting plate moves upward along the inclined surface of the moving inclined block. During the upward movement of the lifting plate, the puncture plate that has not moved upward will be driven to move upward to pierce the air storage airbag. This design can drive the puncture plate that has not risen to move upward, and can prevent the puncture plate that rises alone in the puncture assembly from accidentally failing to pierce the air storage airbag, resulting in the inert gas being unable to be discharged smoothly.
[0021] 4. The air introduced into the air guide hose of the present invention will also enter the soft branch pipe. Since the elastic force of the spring five is greater than the elastic force of the spring four, the air will first push the sliding rod two to compress the spring four. When the sliding rod two moves to the final position, as the pressure plate continues to push the air into the air guide hose, the air will enter the fixed sleeve two through the soft branch pipe. The air introduced into the fixed sleeve two will push the sliding curved rod in the direction away from the puncture plate and compress the spring five. The sliding curved rod will drive the puncture plate to move together during the movement. The puncture plate will pull the air storage airbag through the spikes that pierce the air storage airbag during the movement, thereby increasing the size of the damaged opening of the air storage airbag. This design can prevent the air storage airbag from rupturing after the puncture plate pierces the air storage airbag, resulting in the spikes remaining in the air storage airbag to block the damaged opening, making it impossible for the inert gas to be discharged quickly.

[0042] The bottom of the lifting rod 303 is fixedly connected to the top of the moving plate 209, and a pressure plate 304 is fixedly connected to the top of the lifting rod 303. The outer surface of the pressure plate 304 is slidably connected to the inner wall of the gas storage shell 302. The bottom of the support plate 301 is fixedly connected to an air guide hose 305. The end of the air guide hose 305 away from the support plate 301 is fixedly connected to the inner wall of the shell 101. An air guide cavity 306 is opened inside the shell 101.

The lifting rod 303 03 will drive the pressing plate 304 to move downwards during the movement, and the pressing plate 304 will squeeze the air inside the gas storage shell 302 during the downward movement, and push the air into the air guide hose 305, and the air guide hose 305 will pass the air into the air guide cavity 306, and the air guide cavity 306 will pass the air into the fixed sleeve 1 307, and the air passed into the fixed sleeve 1 307 will push the sliding rod 2 308 towards the direction close to the puncture plate 108 and compress the spring 4 309, and the sliding rod 2 308 will drive the moving inclined plate 108 during the movement. The movable inclined block 310 moves together with the lifting plate 311.

Since the elastic force of the spring 5 315 is greater than the elastic force of the spring 4 309, the air will first push the sliding rod 2 308 compresses spring four 309. When the sliding rod two 308 moves to the final position, as the pressure plate 304 continues to push air into the air guide hose 305, the air will enter the fixed sleeve two 313 through the soft branch pipe 312. The air entering the fixed sleeve two 313 will push the sliding curved rod 314 in the direction away from the puncture plate 108 and compress the spring five 315. The sliding curved rod 314 will drive the puncture plate 108 to move together during the movement. The puncture plate 108 will pull the air storage airbag 103 through the spikes that pierce the air storage airbag 103 during the movement, so that the damaged opening of the air storage airbag 103 is enlarged. This design can prevent the air storage airbag 103 from rupturing after the puncture plate 108 pierces the air storage airbag 103, resulting in the spikes remaining in the air storage airbag 103 to block the damaged opening, so that the inert gas cannot be discharged quickly.
[0044] The protection method of the distribution box protection structure includes the following steps:
[0045] S1: When the temperature at the location of any one of the magnets 111 rises abnormally, the connecting frame 110 and the piercing plate 108 will move upward as a whole under the action of the spring 109, thereby piercing the air storage bag 103, and the compressed inert gas in the air storage bag 103 will be discharged;
[0046] S2: When any puncture plate 108 moves upward, it will drive the sliding plate 202 to move upward, the main circuit of the device will be disconnected, the electric telescopic rod 208 will be started, and then drive the sealing plate 212 to seal the vent of the housing 101;
[0047] S3: When the movable plate 209 moves downward, the pressing plate 304 pushes the air into the air hose 305, thereby pushing the inclined block 310 to move, and all the puncture plates 108 are lifted upward. The air entering the air hose 305 also enters the soft branch tube 312, thereby driving the puncture plates 108 to move.
[0048] A specific application of this embodiment is:
[0049] When using the device, first install the device to the designated position, and the magnet 111 can be installed at a position where high temperature is easily generated. When the temperature at the position where any of the magnets 111 is located rises abnormally, the magnetism of the magnet 111 will gradually decrease due to the influence of the high temperature. When the temperature at the position reaches a dangerous level, the magnetism of the magnet 111 has been reduced to the point where it can no longer adsorb the connecting frame 110. At this time, the connecting frame 110 and the piercing plate 108 will move upward as a whole under the action of the spring 109. It should be noted that the spring 109 is already in a compressed state when installed. When the piercing plate 108 moves upward, it will drive the spike fixed on its top to move upward together. When the spike contacts the gas storage bag 103, the gas storage bag 103 will be punctured. At this time, the compressed inert gas in the gas storage bag 103 will be discharged and then filled into the interior of the housing 101 to prevent the generation of open flames. This design can prevent the distribution box from abnormally increasing the temperature at a local position due to factors such as humidity, thereby generating open flames and causing greater economic losses and safety hazards by automatically monitoring and responding to high temperature conditions.
[0050] When any puncture plate 108 moves upward, it will drive the sliding plate 202 to move upward and stretch the spring 203. When the sliding plate 202 moves upward, it will drive the joint 1 204 to move upward. When the joint 1 204 moves to separate from the joint 2 205, the total circuit of the device will be disconnected, thereby preventing the device from continuing to work and causing the temperature to continue to rise. When the sliding plate 202 moves upward, it will also drive the joint 3 206 to move upward. When the joint 3 206 moves to contact the joint 4 207, the electric telescopic rod 208 will pass through the power supply separately set for it, and the electric telescopic rod 208 will be connected to the power supply separately set for it. After the rod 208 is activated, it will push the moving plate 209 to move downward. During the downward movement of the moving plate 209, the sealing plate 212 will be driven downward by the spring three 211, and then the vent of the housing 101 will be sealed by the sealing plate 212. When the moving plate 209 needs to continue to move downward, the pressure rod 210 will compress the spring three 211 to continue to move downward. This design can disconnect the main power supply when the temperature of the device is abnormal to prevent the temperature from continuing to rise. The device can also be sealed by the sealing plate 212 to prevent the inert gas from exchanging with the external air, resulting in the conditions for generating open flames inside the housing 101.
[0051] When the movable plate 209 moves downward, it will also drive the lifting rod 303 to move downward. When the lifting rod 303 moves, it will drive the pressing plate 304 to move downward. When the pressing plate 304 moves downward, it will squeeze the air inside the gas storage shell 302 and push the air into the air guide hose 305. The air guide hose 305 will pass the air into the air guide cavity 306. The air guide cavity 306 will pass the air into the fixed sleeve 1 307. The air passed into the fixed sleeve 1 307 will push the sliding rod 2 308 towards the puncture plate 108 and compress the spring 4 309. The movable rod 308 will drive the movable inclined block 310 to move together during the movement, and the movable inclined block 310 will squeeze the lifting plate 311 during the movement, so that the lifting plate 311 moves upward along the inclined surface of the movable inclined block 310. During the upward movement of the lifting plate 311, the puncture plate 108 that has not moved upward will be driven to move upward to puncture the gas storage bag 103. This design can drive the puncture plate 108 that has not risen to move upward, and can prevent the puncture plate 108 that rises alone in the puncture assembly 1 from accidentally failing to puncture the gas storage bag 103, resulting in the inert gas being unable to be discharged smoothly.
[0052] The air passed into the air guide hose 305 will also enter the soft branch tube 312. Since the elastic force of the spring five 315 is greater than the elastic force of the spring four 309, the air will first push the sliding rod two 308 to compress the spring four 309. When the sliding rod two 308 moves to the final position, as the pressure plate 304 continues to push the air into the air guide hose 305, the air will enter the fixed sleeve two 313 through the soft branch tube 312. The air passed into the fixed sleeve two 313 will push the sliding curved rod 314 in the direction away from the puncture plate 108. By pushing and compressing the spring five 315, the sliding bent rod 314 will drive the puncture plate 108 to move during the movement. During the movement, the puncture plate 108 will pull the air storage airbag 103 through the spikes pierced into the air storage airbag 103, so that the damaged opening of the air storage airbag 103 is enlarged. This design can prevent the air storage airbag 103 from rupturing after the puncture plate 108 pierces the air storage airbag 103, resulting in the spikes remaining in the air storage airbag 103 to block the damaged opening, so that the inert gas cannot be discharged quickly.
