When the fire source sensor 10 senses the fire point in the cabinet 1, the fire source sensor 10 controls the electric lead screw 12 and the electric screw 15 to rotate through the control module, so that the movable block 13 drives the nozzle 14 to move to the position corresponding to the fire point. Then the high-pressure fire extinguishing agent bottle 8 discharges the carbon dioxide fire extinguishing agent into the nozzle 14 through the hose 9, and the nozzle 14 sprays the carbon dioxide fire extinguishing agent to put out the fire.

The frame 5 is fixedly connected to the lower part of the left and right sides of the cabinet 1, and the electric rotating blade 6 is installed on the inside of the frame 5. When the electric rotating blade 6 rotates, the electric rotating blade 6 can discharge the hot air in the cabinet 1.

[0037] See also Figure 5As shown, the distribution board with a protective structure also includes a shock absorbing component, which includes a support frame 16, a buffer air bag 161 and an elastic telescopic rod 162. A support frame 16 is arranged under the cabinet 1, and buffer air bags 161 are symmetrically installed on the left and right sides of the top of the support frame 16. The four buffer air bags 161 are fixedly connected to the outer bottom of the cabinet 1, and the four corners of the top of the support frame 16 are rotatably connected to the lower part of the outer side surface of the cabinet 1 with elastic telescopic rods 162. The elastic telescopic rod 162 can realize buffering and shock absorption of the cabinet 1. The elastic telescopic rod 162 is composed of a sleeve, a sliding rod and a spring, wherein the sleeve is rotatably connected to the top of the support frame 16, the sliding rod is slidably connected in the sleeve, the top of the sliding rod is rotatably connected to the lower part of the outer side surface of the cabinet 1, and the spring is connected between the sliding rod and the inner side of the sleeve.

[0038] First, pull the cabinet door 2 forward to swing open, then install the components needed for the switchboard on the mounting frame 4, then push the cabinet door 2 backward to swing closed, then operate the control panel 21 to control the fire source sensor 10 to start, and the fire source sensor 10 monitors the inside of the cabinet 1, and at the same time operate the control panel 21 to control the electric rotating blade 6 to rotate, and the electric rotating blade 6 rotates to draw the heat in the cabinet 1 into the frame 5, and the heat in the frame 5 is discharged by the electric rotating blade 6 to prevent the temperature in the cabinet 1 from being too high and affecting the use of components. At the same time, air is discharged into the cabinet through the air inlet 22 of the cabinet 1 1, the air flows and contacts the components in the cabinet 1, and this is repeated, so that the air can continuously flow in the cabinet 1 to dissipate the heat of the components, thereby achieving a ventilation effect. When the cabinet 1 is accidentally touched, the elastic telescopic rod 162 and the buffer airbag 161 can buffer and reduce shock to the cabinet 1 to prevent the components in the cabinet 1 from being damaged by vibration, thereby ensuring the normal use of the components. At the same time, under the action of the support frame 16, a distance can be created between the cabinet 1 and the ground to prevent the cabinet 1 from being corroded by contact with residual water on the ground, thereby improving the safety of the cabinet 1.When the components of the cabinet 1 are used for a long time and a short circuit occurs and a fire occurs, the fire source sensor 10 monitors the position of the fire point. The fire source sensor 10 first controls the electric rotating blade 6 to stop rotating through the control module, so that the air in the cabinet 1 stops flowing. Then the fire source sensor 10 controls the electric screw 15 and the electric lead screw 12 to rotate through the control module. The electric screw 15 rotates to drive the movable seat 11 to move up and down, and the movable seat 11 drives the movable block 13 to move up and down. The movable block 13 drives the nozzle 14 to move up and down. At the same time, the electric lead screw 12 rotates to drive the movable block 13 to move left and right, and the movable block 13 drives the nozzle 14 to move left and right. The nozzle 14 moves up and down and left and right to move the hose 9. Under the action of the connecting spring 152, the tensioning wheel 151 can keep the hose 9 in a taut state to prevent the hose 9 from loosening and tying. When the nozzle 14 moves up and down and left and right to correspond to the fire point, high pressure fire extinguishing is carried out. The agent bottle 8 discharges the carbon dioxide fire extinguishing agent into the hose 9, and the hose 9 discharges the carbon dioxide fire extinguishing agent into the nozzle 14. The nozzle 14 sprays the carbon dioxide fire extinguishing agent toward the fire point, thereby accurately extinguishing the fire to prevent other locations from being burned and causing major accidents, thereby improving safety. When the fire is extinguished, the fire source sensor 10 does not detect the light source, the high-pressure fire extinguishing agent bottle 8 is closed, and the carbon dioxide fire extinguishing agent stops being sprayed through the nozzle 14. At the same time, the fire source sensor 10 also controls the electric screw 15 to rotate through the control module to drive the movable seat 11 to move upward to the original position. The movable seat 11 drives the nozzle 14 to move upward and reset through the movable block 13. The operator can pull the cabinet door 2 to swing forward and open it, and the damaged components can be replaced. At the same time, other components in the cabinet 1 are checked to ensure that the components can be used normally. When the components are replaced, the cabinet door 2 is pushed to swing backward and closed, and the fire source sensor 10 continues to monitor the cabinet 1.

[0039] See also Figure 6-Figure 8As shown, the switchboard with a protective structure also includes a sealing component installed between the cabinet 1 and the frame 5, the sealing component includes a swing plate 17, a driving component, an L-shaped rod I 177, an L-shaped rod II 178 and a rotating tube 179, and the left and right frames 5 are rotatably connected to each other at even intervals. When the swing plates 17 are swung and retracted, the swing plates 17 can close the frame 5. The shaft of the swing plate 17 is symmetrically fixed with an L-shaped rod I 177, and the lower parts of the left and right sides of the cabinet 1 are rotatably connected with rotating tubes 179. The rotating tube 179 is connected to the air inlet 22 of the cabinet 1, and the rotating tube 179 is symmetrically opened with a straight hole, and the rotating tube 179 is symmetrically fixed with an L-shaped rod II 178. A driving assembly is provided on the cabinet 1. When the driving assembly is in operation, the driving assembly can drive the L-shaped rod Ⅰ177 and the L-shaped rod Ⅱ178 to swing; the driving assembly includes a sliding frame 171, a cylinder 172, a straight hole block Ⅰ175 and a straight hole block Ⅱ176. The cylinders 172 are fixedly connected to the lower parts of the left and right sides of the cabinet 1, and the ends of the telescopic rods of the cylinders 172 on the left and right sides are fixedly connected to the sliding frame 171. Three straight hole blocks Ⅰ175 are fixedly connected to the middle parts of the front and rear sides of the sliding frame 171. The inner side of the straight hole block Ⅰ175 is slidably connected to the end of the L-shaped rod Ⅰ177. The four bottom ends of the sliding frame 171 are fixedly connected to the straight hole blocks Ⅱ176. The inner sides of the four straight hole blocks Ⅱ176 are respectively slidably connected to the ends of the four L-shaped rods Ⅱ178.

[0040] See also Figure 9-11 As shown, the switchboard with a protective structure also includes a moisture-proof component installed on the cabinet 1, and the moisture-proof component includes an injection pipe 18, an air intake pipe 1801, an air pump 1802 and a cooling component. The front part of the left and right side partitions 3 close to each other is fixedly connected with the injection pipe 18, and the injection end of the injection pipe 18 faces the rear side. The injection pipe 18 can spray hot air to keep the cabinet 1 dry. The top ends of the left and right side injection pipes 18 are connected with the air intake pipe 1801, and the air intake end of the air intake pipe 1801 passes through the left side of the cabinet 1. The air pump 1802 is installed on the upper left side surface of the cabinet 1. The air pump 1802 is used to spray hot air, and the air outlet end of the air pump 1802 is connected to the air intake pipe 1801. The cabinet 1 is connected and communicated with the air inlet end thereof, and a cooling assembly is arranged on the cabinet 1, which can absorb the heat in the cabinet 1; the cooling assembly includes a heat sink Ⅰ181, a heat sink Ⅱ182, a cooling pipe 183 and a refrigeration box 184, a heat sink Ⅰ181 is installed on the inner rear side of the cabinet 1, a heat sink Ⅱ182 is fixedly connected in the cavity at the lower part of the cabinet 1, a desiccant can be placed inside the heat sink Ⅱ182, a refrigeration box 184 is installed on the lower part of the outer rear side of the cabinet 1, a cooling pipe 183 is connected to the refrigeration box 184, the cooling pipe 183 runs through the heat sink Ⅱ182 and the heat sink Ⅰ181, and the cooling pipe 183 can cool the heat sink Ⅱ182 and the heat sink Ⅰ181.

[0041] Initially, the compression spring 174 is in a compressed state. When air is discharged through the air inlet 22 of the cabinet 1, the air passes through the rotating tube 179 and is discharged into the cavity below the cabinet 1. Then, when the fire source sensor 10 detects the ignition point, the cylinder 172 is started, and the telescopic rod of the cylinder 172 is extended to drive the sliding frame 171 to move downward. The sliding frame 171 moves downward to drive the slotted hole block I 175 and the slotted hole block II 176 to move downward. The slotted hole block II 176 moves downward to drive the L-shaped rod II 178 to swing downward. The L-shaped rod II 178 swings downward to drive the rotating tube 179 to rotate ninety degrees. The rotating tube 179 rotates ninety degrees to block the air inlet 22 of the cabinet 1, and the air stops. Enter the cabinet 1, and at the same time, the slotted hole block Ⅰ175 moves downward to drive the L-shaped rod Ⅰ177 to swing downward. The downward swing of the L-shaped rod Ⅰ177 drives the three swing plates 17 to swing downward to a vertical state. The three swing plates 17 contact each other to close the frame 5. When the electric rotating blade 6 stops rotating, the outside air will not be discharged into the cabinet 1 through the frame 5, and there will be no air flow in the cabinet 1. At this time, the nozzle 14 moves to correspond to the ignition point, and the nozzle 14 sprays carbon dioxide fire extinguishing agent to put out the fire. Since there is no air flow in the cabinet 1, the fire is quickly extinguished. At the same time, the rotating tube 179 and the swing plate 17 can block the smoke and dust produced by the extinguishing. When the fire is extinguished, the telescopic rod of the cylinder 172 shortens and drives the sliding frame 171 to move upward and reset, and the sliding frame 171 moves upward and drives the slotted hole block I175 and the slotted hole block II176 to move upward and reset, and the slotted hole block I175 drives the L-shaped rod I177 to swing upward and reset, so that the swing plate 17 swings upward and resets to stop sealing the frame 5, and at the same time, the slotted hole block II176 drives the rotating tube 179 to rotate 90 degrees through the L-shaped rod II178 to reset and rotate and connect with the cabinet 1, and the air can continue to be discharged through the air inlet 22 of the cabinet 1. In this way, a large amount of air can be prevented from entering the cabinet 1 when a fire occurs, causing the fire to become larger and causing a greater accident, thereby ensuring the rapid extinguishing of the fire source, and preventing smoke and dust from floating out of the cabinet 1 to affect the surrounding environment, thereby ensuring the air quality of the surrounding environment.

[0042] When a humid environment occurs, there is still a lot of moisture in the air. When the air containing moisture enters the cabinet 1, it is easy to cause the components in the cabinet 1 to become damp. When the air enters the cabinet 1 through the air inlet 22, the air first contacts the desiccant inside the heat sink II. The desiccant initially absorbs and removes the moisture in the air. Then the air continues to flow into the cabinet 1. At this time, the air pump 1802 is started to discharge the hot air into the air inlet pipe 1801. The hot air in the air inlet pipe 1801 is discharged into the jet pipe 18. The jet pipe 18 discharges the hot air into the cabinet 1. The hot air dries the cabinet 1, so that the components in the cabinet 1 are in a dry state. At the same time, due to the non- The temperature in the cabinet 1 will rise continuously, and the heat sink Ⅰ181 and the heat sink Ⅱ182 will absorb the heat in the cabinet 1. At the same time, the refrigeration box 184 is started, and the refrigeration box 184 allows the liquid to circulate in the cooling pipe 183. The liquid takes away the absorption on the heat sink Ⅰ181 and the heat sink Ⅱ182 through the cooling pipe 183, and the heat sink Ⅰ181 and the heat sink Ⅱ182 are cooled to prevent the heat sink Ⅰ181 and the heat sink Ⅱ182 from being too high in temperature and affecting the absorption of heat. At the same time, the heat sink Ⅱ182 can buffer the air entering the cabinet 1, so that the moisture is removed before the air completely enters the cabinet and contacts the components. When the components in the cabinet 1 are dry, the air pump 1802 is turned off, the hot air stops being discharged into the air inlet pipe 1801, the jet pipe 18 stops ejecting the hot air, and then the refrigeration box 184 is turned off, and the liquid in the cooling pipe 183 stops flowing. In this way, the risk of damage caused by short circuit of components due to moisture in the cabinet 1 can be prevented, thereby improving the drying effect in the cabinet 1.

[0043] See also Fig.12 As shown, the switchboard with a protective structure also includes a transparent plate 19, and the transparent plate 19 is fixedly connected to the lower front part of the cabinet door 2.

[0044] When the components in the cabinet 1 have been used for a long time, the operator can check the usage of the components in the cabinet 1 through the transparent plate 19, without having to pull the cabinet door 2 open for viewing, which is more convenient. In this way, the status of the components can be controlled in time, so that corresponding processing can be made.
