Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-7 , an embodiment of the present invention is: A power cabinet with a moisture-proof function, including a cabinet 1, a component board 2 is arranged inside the cabinet 1, a dehumidification mechanism 3 is arranged at the bottom of the inner wall of the cabinet 1, a filter mechanism 4 is arranged at the bottom right of the cabinet 1, and a cabinet door 6 is rotatably connected to the front of the cabinet 1; the dehumidification mechanism 3 includes: a filter barrel 301, a filter barrel bracket 309 is fixedly connected to the inner wall of the cabinet 1, a filter barrel 301 is rotatably connected to the right side of the filter barrel bracket 309, the outer shell 310 is distributed with air holes and fixedly connected to the bottom of the inner wall of the cabinet 1, a fan bracket 302 is fixedly connected to the inner wall of the cabinet 1, a double-shaft motor 303 is fixedly connected to the left side of the fan bracket 302, the right output end of the double-shaft motor 303 is fixedly connected to a fan 304, the left side of the fan 304 is in contact with the right side of the fan bracket 302, and the fan 304 is located inside the outer shell 310. The dehumidification mechanism 3 further includes: a belt 305, a first transmission rod 306, a first gear 307, and a gear ring 308. The first transmission rod 306 is connected to the left output end of the double-shaft motor 303 through the belt 305, the first gear 307 is fixedly connected to the circumferential surface of the first transmission rod 306, the gear ring 308 is fixedly connected to the circumferential surface of the filter barrel 301, and the gear ring 308 meshes with the first gear 307.

[0020] Working principle: During the normal operation of the power cabinet, the motor 303 starts the right output end to drive the fan 304 to rotate to suck in air. The air enters the filter cartridge 301 and contacts the desiccant inside it, thereby drying the air and preventing the humid air from entering the box body 1 and causing the internal circuit to be affected by moisture and short - circuit. At the same time, the left output end of the motor 303 drives the first transmission rod 306 to rotate through the belt 305. The rotation of the first transmission rod 306 drives the first gear 307 to mesh with the gear ring 308, and the gear ring 308 also starts to rotate. The rotation of the gear ring 308 drives the filter barrel 301 to rotate. The rotation of the filter cartridge 301 can turn the desiccant inside it to ensure that the internal desiccant can fully contact the air.

[0021] When the filter barrel 301 rotates, it drives the gear ring 308 to rotate accordingly, which in turn drives the second gear 408 to rotate. The rotation of the second gear 408 causes the second transmission rod 407 to rotate. The rotation of the second transmission rod 407 makes the cam 403 rotate. During the rotation of the cam 403, it contacts the top push plate 404. The continuous rotation pushes the push plate 404 to rotate around the torsion spring in the middle. The rotation of the top push plate 404 drives the connecting rod 405 to move downward, ensuring that all push plates 404 rotate synchronously. When the device intakes air, the push plate 404 swings reciprocally to increase its air intake range. When the push plate 404 rotates, the push plate 404 will push the filter plate 401. Due to the restriction of the inner wall track of the frame 410, the filter plate 401 can only move along the right side. When the filter plate 401 moves, it compresses the first spring reset device 402. When the convex part of the cam 403 passes over the push plate 404, the first spring reset device 402 will reset and push the filter plate 401 back to its original position. The reciprocating movement of the filter plate 401 helps prevent dust accumulation. When the filter plate 401 needs to be replaced, pull open the retaining bar 409, and at the same time, the swinging push plate 404 stays in the middle most position, making the distance that the filter plate 401 is pushed reach the maximum value. At this time, the filter plate 401 can be taken out along the vertical track direction of the inner wall of the frame 410.

[0022] Please refer to Figures 1-7 Based on the above - mentioned embodiment, in another embodiment of the present invention, the filtering mechanism 4 includes: a filter plate 401, a first spring reset device 402, a retaining bar 409, and a frame 410. The filter plate 401 is slidably connected to the L - shaped chute on the inner wall of the frame 410. The retaining bar 409 is slidably connected to the top of the frame 410. The first spring reset device 402 is fixedly connected to the right side of the inner wall of the frame 410.

[0023] The filtering mechanism 4 further includes: a cam 403, a push plate 404, a connecting rod 405, a first fixing block 406, a second transmission rod 407, and a second gear 408. The first fixing block 406 is fixedly connected to the top of the fan bracket 302. The second transmission rod 407 is rotatably connected to the inner wall of the first fixing block 406. The inner wall of the second gear 408 is fixedly connected to the circumferential surface of the second transmission rod 407. The cam 403 is fixedly connected to the right side of the second transmission rod 407. The push plate 404 is rotatably connected to the inner wall of the frame 410 through a torsion spring. The connecting rod 405 is rotatably connected to both sides of the push plate 404.

[0024] The cam 403 contacts the push plate 404, the filter plate 401 contacts the push plate 404, the second gear 408 meshes with the gear ring 308, and the first spring return device 402 contacts the filter plate 401.

[0025] The pushing mechanism 5 includes: a first slide rail 501, a first slider 502, a pull rod 503, a connecting block 504, a second slide rail 508, and a second slider 509. The first slide rail 501 is fixedly connected to the right side of the cabinet door 6. The first slider 502 is slidably connected to the surface groove of the first slide rail 501. The pull rod 503 is rotatably connected to the surface of the first slider 502. The connecting block 504 is fixedly connected to the surface of the component board 2. The second slider 509 is fixedly connected to the surface of the component board 2. The second slide rail 508 is fixedly connected to the inner wall of the box body 1. The second slider 509 is slidably connected to the inner wall groove of the second slide rail 508.

[0026] The pushing mechanism 5 further includes: a convex block 505, a second fixing block 506, a push rod 507, a clamping block 510, a component clamping plate 511, and a second elastic return device 512. The convex block 505 is fixedly connected to the inner wall of the box body 1. The second fixing block 506 is fixedly connected to the front surface of the component board 2. The circumferential surface of the push rod 507 is slidably connected to the inner wall of the second fixing block 506. The clamping block 510 is fixedly connected to the inside of the push rod 507. The component clamping plate 511 is rotatably connected to the surface of the component board 2 through a torsion spring. The second elastic return device 512 is arranged on the right side of the push rod 507.

[0027] The convex block 505 is located on the movement track of the push rod 507, and the surface of the clamping block 510 contacts the inner wall of the component clamping plate 511.

[0028] Working principle: When the power cabinet needs to be overhauled, open the cabinet door 6. The cabinet door 6 rotates along the axis of the rotating shaft and drives the movement of the first slide rail 501. The movement of the first slide rail 501 drives the movement of the first slider 502. The movement of the first slider 502 drives the movement of the pull rod 503. The movement of the pull rod 503 drives the connecting block 504. As the connecting block 504 moves, the component board 2 is pulled out. Due to the restriction of the second slide rail 508 on the component board 2, it can only move along the direction of the second slide rail 508. During the movement, the push rod 507 on the component board 2 contacts the convex block 505 on the box body 1. When moving forward continuously, the push rod 507 is squeezed by the convex block 505 and moves to the right, thereby driving the movement of the second slider 509 and causing the latch 510 to move out of the groove of the component buckle 511. At this time, the component buckle 511 loses its restraint and rotates in the direction of the left torsion spring reset of the component buckle 511. The opening of the component buckle 511 loosens the electrical components. At the same time, the component board 2 also moves to the opening of the cabinet door 6, thus facilitating overhaul and replacement.

[0029] The present invention provides a power cabinet with a moisture-proof function. There are many methods and ways to specifically implement this technical solution. The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. Each component not clearly defined in this embodiment can be implemented by existing technologies.
