The restoration of the second spring drives the sliding plate to reset.

[0010] According to the above technical solution, the first cleaning rod is slidably connected above the sliding plate, and the second cleaning rod is slidably connected to the surface of the first filter plate. The rotation of the first cleaning rod drives the fixed shaft to rotate. The rotation of the fixed shaft drives the second cleaning rod to rotate.

[0011] According to the above technical solution, the protection device includes a second connecting rod, a threaded rod, a lifting rod, a baffle, a sleeve, a limiting groove and a limiting block. The second connecting rod is fixedly installed below the first connecting rod. The threaded rod is fixedly installed at one end of the second connecting rod away from the first connecting rod. The lifting rod is rotatably installed on the circumferential surface of the threaded rod. The baffle is fixedly installed on the surface of the lifting rod. The sleeve is rotatably installed on the circumferential surface of the second connecting rod. The limiting groove is opened on the surface of the sleeve. The limiting block is slidably installed on the inner wall of the limiting groove. When the power distribution cabinet dissipates heat, the double-shaft motor is started. The output end of the double-shaft motor rotates to drive the heat dissipation fan to rotate. The rotation of the heat dissipation fan drives the first connecting rod to rotate. The rotation of the first connecting rod drives the second connecting rod to rotate. The rotation of the second connecting rod drives the threaded rod to rotate. The rotation of the threaded rod drives the lifting rod to move upward. The movement of the lifting rod drives the baffle to move upward. The movement of the baffle communicates with the air outlet.

[0012] According to the above technical solution, a third spring is arranged between the limiting block and the sleeve. The baffle is slidably connected to the inner wall of the cabinet body. When the lifting rod moves upward, it contacts the limiting block. The limiting block moves into the limiting groove under the action of the lifting rod. The movement of the limiting block compresses the third spring to contract. The restoration of the third spring drives the limiting block to reset. The reset of the limiting block limits the lifting rod. The limiting of the lifting rod limits the baffle, providing additional support for the baffle.

[0013] According to the above technical solution, the sleeve is fixedly connected to the lower part of the heat dissipation frame. The lifting rod is slidably connected to the sleeve. The lifting rod is threadedly connected to the circumferential surface of the threaded rod. When the heat dissipation stops, the limiting block is pushed into the limiting groove.

The movement of the lifting rod drives the baffle to move. The movement of the baffle closes the air outlet.

[0014] The present invention provides a power distribution cabinet with a heat dissipation function. It has the following beneficial effects: (1) For the power distribution cabinet with a heat dissipation function, through the setting of the moisture-proof device, the first filter plate, the sliding plate, the first connecting rod, the heat dissipation frame, the moisture-removing frame and the stirring rod cooperate with the vibration block. When the outside air enters the interior of the moisture-removing frame, it contacts the desiccant and removes the moisture therein under its action, preventing the humid air from entering the interior of the cabinet body and damaging the equipment. It can make the desiccant evenly distributed in the container, ensuring that the moisture in the air can fully contact the desiccant, preventing the humid air from entering the interior of the cabinet body and damaging the equipment. The vibration of the vibration block drives the moisture-removing frame to vibrate, which can prevent the desiccant from caking, extend the effective service life of the desiccant, reduce the need for frequent replacement, and at the same time can prevent the formation of sediments, ensuring the safety of the desiccant during use.

[0015] (2) In the power distribution cabinet with heat dissipation function, through the arrangement of the cleaning device, the first rotating shaft, the first gear block, the second rotating shaft, the second gear block, the first cleaning rod and the fixed shaft cooperate with the second cleaning rod. The first cleaning rod rotates to clean the upper part of the sliding plate, which can be cleaned under specific conditions, reduce wear, extend the service life of the equipment, help reduce the maintenance and replacement requirements of the equipment, thereby reducing the maintenance cost. The second cleaning rod rotates to clean the surface of the first filter plate, avoiding the surface of the first filter plate being blocked by foreign objects and impurities, affecting the air intake effect and causing an impact on the heat dissipation of the equipment.

[0016] (3) In the power distribution cabinet with heat dissipation function, through the arrangement of the protection device, the second connecting rod, the threaded rod, the lifting rod, the baffle plate, the sleeve and the limiting groove cooperate with the limiting block. The baffle plate moves to communicate with the air outlet, which can timely discharge the hot air, avoid the internal temperature being too high and affecting the normal operation of the equipment. The baffle plate is limited to keep communicating with the air outlet, providing additional support for the baffle plate and maintaining the stability of the baffle plate during the heat dissipation process, avoiding it shaking all the time during the heat dissipation process and thus affecting the heat dissipation effect.

[0021] A first spring 12 is provided between the dehumidification frame 9 and the heat dissipation frame 8. One side of the vibration block 11 close to the stirring rod 10 is provided with an inclined section. The first connecting rod 7 penetrates the upper and lower walls of the dehumidification frame 9.

[0022] During the operation of this embodiment: When dissipating heat from the power distribution cabinet, the dual-axis motor 3 is started. The lower output end of the dual-axis motor 3 rotates to drive the cooling fan 4 to rotate. The rotation of the cooling fan 4 introduces external air into the interior of the cabinet 1. The external air enters the interior of the dehumidification frame 9, contacts the desiccant, and removes the moisture therein under its action, preventing humid air from entering the interior of the cabinet 1 and damaging the equipment. The rotation of the cooling fan 4 drives the rotation of the first connecting rod 7, the rotation of the first connecting rod 7 drives the rotation of the stirring rod 10, and the rotation of the stirring rod 10 contacts the inclined plane of the vibration block 11.

[0024] A second spring 138 is provided between the sliding plate 6 and the cooling fan 4. The first gear block 132 meshes with the second gear block 134. When the sliding plate 6 moves downward, it compresses the second spring 138 to contract. After the sliding plate 6 is cleaned, the second spring 138 restores, and the restoration of the second spring 138 drives the sliding plate 6 to reset.

[0025] The first cleaning rod 135 is slidably connected to the upper part of the sliding plate 6, and the second cleaning rod 137 is slidably connected to the surface of the first filter plate 5. The rotation of the second cleaning rod 137 cleans the surface of the first filter plate 5, preventing the surface of the first filter plate 5 from being blocked by foreign objects and impurities, affecting the air intake effect, and resulting in an impact on the heat dissipation of the equipment.

[0026] The protection device includes a second connecting rod 141, a threaded rod 142, a lifting rod 143, a baffle 144, a sleeve 145, a limiting groove 146 and a limiting block 147.

When the power distribution cabinet dissipates heat, the baffle 144 moves to communicate with the air outlet 2, and can timely discharge the hot air, avoiding the internal temperature being too high and affecting the normal operation of the equipment.

[0027] A third spring 148 is arranged between the limiting block 147 and the sleeve 145. The baffle 144 is slidably connected to the inner wall of the cabinet body 1. The baffle 144 is limited to keep communicating with the air outlet 2, providing additional support for the baffle 144 and maintaining the stability of the baffle 144 during the heat dissipation process, avoiding it shaking all the time during the heat dissipation process and thus affecting the heat dissipation effect.

After the lifting rod 143 is released from the limitation, it moves downward. The movement of the lifting rod 143 drives the baffle 144 to move, and the baffle 144 moves to close the air outlet 2.

[0029] When this embodiment works: when impurities accumulate above the sliding plate 6, the sliding plate 6 moves downward under the action of the impurities. The movement of the sliding plate 6 drives the second rotating shaft 133 to move downward. The movement of the second rotating shaft 133 drives the second gear block 134 to move. The second gear block 134 moves to contact and mesh with the first gear block 132. At this time, the upper output end of the dual-axis motor 3 rotates to drive the first rotating shaft 131 to rotate. The rotation of the first rotating shaft 131 drives the first gear block 132 to rotate. The rotation of the first gear block 132 drives the second gear block 134 to rotate. The rotation of the second gear block 134 drives the second rotating shaft 133 to rotate. The rotation of the second rotating shaft 133 drives the first cleaning rod 135 to rotate around the second rotating shaft 133. The rotation of the first cleaning rod 135 cleans the area above the sliding plate 6. It can be cleaned under specific conditions, reducing wear and extending the service life of the equipment. It helps to reduce the maintenance and replacement requirements of the equipment, thereby reducing the maintenance cost. The rotation of the first cleaning rod 135 drives the fixed shaft 136 to rotate. The rotation of the fixed shaft 136 drives the second cleaning rod 137 to rotate. The rotation of the second cleaning rod 137 cleans the surface of the first filter plate 5, avoiding the surface of the first filter plate 5 being blocked by foreign objects and impurities, affecting the air intake effect and resulting in an impact on the heat dissipation of the equipment.

[0030] When the power distribution cabinet dissipates heat, the rotation of the first connecting rod 7 drives the rotation of the second connecting rod 141. The rotation of the second connecting rod 141 drives the rotation of the threaded rod 142. The rotation of the threaded rod 142 drives the lifting rod 143 to move upward. The upward movement of the lifting rod 143 drives the baffle 144 to move upward. The upward movement of the baffle 144 releases the blockage of the air outlet 2, enabling the timely discharge of hot air, avoiding excessive internal temperature and affecting the normal operation of the equipment. The upward movement of the lifting rod 143 contacts the limit block 147. Under the action of the lifting rod 143, the limit block 147 moves into the limit groove 146. The movement of the limit block 147 compresses the third spring 148 to contract. The restoration of the third spring 148 drives the limit block 147 to reset. The reset of the limit block 147 limits the lifting rod 143. The limitation of the lifting rod 143 limits the baffle 144. The limitation of the baffle 144 keeps the air outlet 2 connected, provides additional support for the baffle 144, and maintains the stability of the baffle 144 during the heat dissipation process, preventing it from shaking continuously during the heat dissipation process and thus affecting the heat dissipation effect.
