Detailed Embodiment

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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 of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1 - 9, an embodiment of the present invention is: an outdoor power distribution cabinet with dust prevention and ventilation, including a cabinet body 1. The inner wall of the cabinet body 1 is rotatably connected with a cabinet door 2. The inner wall of the cabinet body 1 is fixedly connected with a fixed seat 5. The inner wall of the fixed seat 5 is fixedly connected with a bidirectional motor 6. The output end of the bidirectional motor 6 is fixedly connected with a reciprocating lead screw 7. The inner wall of the cabinet body 1 is fixedly connected with a dust-proof cover 8. The circumferential surface of the reciprocating lead screw 7 is fixedly connected with fan blades 9. When the device is placed outdoors for use, the temperature sensor inside the cabinet body 1 detects that the temperature inside the cabinet body 1 is too high. At this time, the bidirectional motor 6 will start, and the output end of the bidirectional motor 6 will drive the reciprocating lead screw 7 to rotate. The rotation of the reciprocating lead screw 7 will drive the fan blades 9 to rotate. During the rotation of the fan blades 9, the air inside the cabinet body 1 can be discharged outward through the dust-proof cover 8. After the air inside the cabinet body 1 is discharged, the outside air can re-enter the inside of the cabinet body 1, enabling the air inside the cabinet body 1 to exchange with the cold air outside, improving the flow and exchange speed of the air inside the cabinet body 1 with the outside air, and enhancing the ventilation and heat dissipation effect of the device. The circumferential surface of the reciprocating lead screw 7 is movably connected with a straight block 10. The inner wall of the fixed seat 5 is fixedly connected with a limiting post 11. The surface of the straight block 10 is fixedly connected with a first fixing block 12. The inner wall of the first fixing block 12 is rotatably connected with a pull rod 13. The surface of the pull rod 13 is rotatably connected with a second fixing block 14. The inner wall of the cabinet body 1 is fixedly connected with an elastic telescopic rod 15. The telescopic end of the elastic telescopic rod 15 is fixedly connected with a pressing plate 16. The rear part of the pressing plate 16 is fixedly connected with the second fixing block 14. The front part of the cabinet door 2 is fixedly connected with a rain-proof plate 17. The inner wall of the cabinet door 2 is rotatably connected with a hinge post 18 through a torsion spring. The circumferential surface of the hinge post 18 is fixedly connected with an opening plate 19. The inner wall of the cabinet body 1 is provided with a cleaning mechanism 3 for dust cleaning. The left side of the cabinet body 1 is provided with a protection mechanism 4 for protecting the ventilation opening. The straight block 10 is slidably connected to the circumferential surface of the limiting post 11. At the same time, during the rotation of the reciprocating lead screw 7, the reciprocating lead screw 7 will drive the straight block 10 to rotate. However, at this time, the straight block 10 is limited by the limiting post 11, so that the straight block 10 can only perform reciprocating horizontal movement through the reciprocating groove on the surface of the reciprocating lead screw 7. The movement of the straight block 10 will drive the first fixing block 12 to move. The first fixing block 12 will drive the pull rod 13 to move. The movement of the pull rod 13 will drive the second fixing block 14 to move. At this time, the second fixing block 14 will squeeze and push the pressing plate 16. After the pressing plate 16 moves a certain distance, the cylinder of the pressing plate 16 itself will contact and squeeze the opening plate 19 and push the opening plate 19. At this time, after the opening plate 19 receives the squeezing force, the opening plate 19 will rotate around the hinge post 18. The rotation of the opening plate 19 can open the ventilation opening of the cabinet door 2. By opening multiple ventilation openings of the device, the ventilation effect can be further improved, the heat dissipation efficiency of the device can be enhanced, enabling the outside cold air to enter the inside of the cabinet body 1 faster, and preventing the temperature inside the cabinet body 1 from being too high and damaging the electronic components inside the cabinet body 1. The temperature sensor is installed inside the cabinet body 1 and is connected to the bidirectional motor 6 through a circuit.

[0016] The cleaning mechanism 3 includes an inclined block 301, a slider 302, an inclined block column 303, a connecting column 304, and a first scraper 305. The inclined block 301 is fixedly connected to the inner wall of the straight block 10. The slider 302 is slidably connected to the inner wall of the cabinet body 1. The inclined block column 303 is fixedly connected to the inner wall of the slider 302. The connecting column 304 is fixedly connected to the top of the slider 302. The first scraper 305 is fixedly connected to the circumferential surface of the connecting column 304. When the device is started, the reciprocating horizontal movement of the straight block 10 will drive the inclined block 301 to move reciprocally. After the inclined block 301 moves a certain distance, the inclined block 301 will contact and squeeze the inclined block column 303 to push the inclined block column 303 upward. The upward movement of the inclined block column 303 will drive the connecting column 304 to move. During the upward movement of the connecting column 304, the connecting column 304 will drive the first scraper 305 to move. The movement of the first scraper 305 can clean the dust and sundries at the ventilation part of the dust-proof cover 8, avoid excessive dust and sundries at the ventilation part of the dust-proof cover 8 from blocking the ventilation port and affecting the ventilation and heat dissipation effect of the device, and improve the ventilation and heat dissipation efficiency of the device. The cleaning mechanism 3 further includes a rotating column 306, a roller 307, and a second scraper 308. The rotating column 306 is rotatably connected to the circumferential surface of the connecting column 304. The roller 307 is fixedly connected to the circumferential surface of the rotating column 306. The second scraper 308 is fixedly connected to the circumferential surface of the rotating column 306. The roller 307 contacts the dust-proof cover 8, and the first scraper 305 contacts the dust-proof cover 8. At the same time, during the up and down movement of the connecting column 304, the connecting column 304 will drive the rotating column 306 to move up and down. The up and down movement of the rotating column 306 will drive the roller 307 to move up and down. When the roller 307 moves up and down, due to the friction force between the roller 307 and the dust-proof cover 8, the roller 307 can rotate. The rotation of the roller 307 will drive the rotating column 306 to move and rotate at the same time. The movement and rotation of the rotating column 306 can drive the second scraper 308 to move and rotate. The second scraper 308 can further scrape off the dust and adhesives at the ventilation part of the dust-proof cover 8, further improve the ventilation effect of the ventilation port of the dust-proof cover 8, avoid some adhesive substances from staying on the surface of the ventilation part of the dust-proof cover 8, and improve the service life of the device. The temperature sensor is installed inside the cabinet body 1 and is connected to the bidirectional motor 6 through a circuit.

[0017] Working principle: When the device is placed outdoors for use, the temperature sensor inside the cabinet body 1 detects that the temperature inside the cabinet body 1 is too high. At this time, the bidirectional motor 6 will start, and the output end of the bidirectional motor 6 will drive the reciprocating screw rod 7 to rotate. The rotation of the reciprocating screw rod 7 will drive the fan blade 9 to rotate. During the rotation of the fan blade 9, the air inside the cabinet body 1 can be discharged outward through the dust-proof cover 8. After the air inside the cabinet body 1 is discharged, the outside air can re-enter the inside of the cabinet body 1, enabling the air inside the cabinet body 1 to exchange with the cold air outside, improving the flow exchange speed of the air inside the cabinet body 1 and the outside air, and improving the ventilation and heat dissipation effect of the device. At the same time, during the rotation of the reciprocating screw rod 7, the reciprocating screw rod 7 will drive the straight block 10 to rotate. However, at this time, the straight block 10 is limited by the limiting column 11, so that the straight block 10 can only move horizontally back and forth through the reciprocating groove on the surface of the reciprocating screw rod 7. The movement of the straight block 10 will drive the first fixing block 12 to move, the first fixing block 12 will drive the pull rod 13 to move, and the movement of the pull rod 13 will drive the second fixing block 14 to move. At this time, the second fixing block 14 will squeeze and push the pressing plate 16. After the pressing plate 16 moves a certain distance, the cylinder of the pressing plate 16 itself will contact and squeeze the opening plate 19 and push the opening plate 19. At this time, after the opening plate 19 receives the squeezing force, the opening plate 19 will rotate around the hinge column 18. The rotation of the opening plate 19 can open the ventilation openings of the cabinet door 2. By opening the multiple ventilation openings of the device, the ventilation effect can be further improved, the heat dissipation efficiency of the device can be improved, enabling the cold air outside to enter the inside of the cabinet body 1 faster, and preventing the temperature inside the cabinet body 1 from being too high and damaging the electronic components inside the cabinet body 1.

[0018] When the device is started, the reciprocating horizontal movement of the straight block 10 will drive the first inclined block 301 to move reciprocally. After the first inclined block 301 moves a certain distance, the first inclined block 301 will contact and squeeze the inclined block column 303 to push the inclined block column 303 to move upward. The upward movement of the inclined block column 303 will drive the connecting column 304 to move. During the upward movement of the connecting column 304, the connecting column 304 will drive the first scraper 305 to move. The movement of the first scraper 305 can clean the dust and sundries at the ventilation part of the dust-proof cover 8, avoid excessive dust and sundries at the ventilation part of the dust-proof cover 8, block the ventilation port, affect the ventilation and heat dissipation effect of the device, and improve the ventilation and heat dissipation efficiency of the device. At the same time, during the up and down movement of the connecting column 304, the connecting column 304 will drive the rotating column 306 to move up and down. The up and down movement of the rotating column 306 will drive the roller 307 to move up and down. When the roller 307 moves up and down, due to the frictional force between the roller 307 and the dust-proof cover 8, the roller 307 can rotate. The rotation of the roller 307 will drive the rotating column 306 to move and rotate at the same time. The moving rotation of the rotating column 306 can drive the second scraper 308 to move and rotate. The second scraper 308 can further scrape off the dust and adhesives at the ventilation part of the dust-proof cover 8, further improve the ventilation effect of the ventilation port of the dust-proof cover 8, avoid some adhesive substances staying on the surface of the ventilation part of the dust-proof cover 8, and improve the service life of the device.

[0019] Please refer to Figures 1 - 9, on the basis of the above embodiments, in another embodiment of the present invention, the protection mechanism 4 includes an electric telescopic rod 401, a connecting plate 402, a protective cover 403, and a sealing strip 407.

When the device is used outdoors and there is a strong wind, the electric telescopic rod 401 will receive a signal from the wind sensor and start. The telescopic end of the electric telescopic rod 401 will drive the connecting plate 402 to move. After the connecting plate 402 moves, the connecting plate 402 can block the ventilation openings on the surface of the dustproof cover 8 from the outside to a certain extent, avoiding excessive dust and debris being driven by the strong wind to contact the dustproof cover 8 in strong wind weather, increasing the cleaning difficulty at the ventilation openings of the dustproof cover 8, and improving the comprehensiveness of the device when used outdoors. The protection mechanism 4 further includes a pushing plate 404, a connecting long plate 405, and a knocking column 406. The pushing plate 404 is fixedly connected to the top of the connecting column 304, the connecting long plate 405 is fixedly connected to the inner wall of the protective cover 403, the knocking column 406 is slidably connected to the inner wall of the connecting long plate 405, the protective cover 403 is slidably connected to the inner wall of the cabinet 1, the sealing strip 407 contacts the cabinet 1. At the same time, during the movement of the connecting column 304, the connecting column 304 will drive the pushing plate 404 to move upward. During the movement of the pushing plate 404, the pushing plate 404 will contact and squeeze the knocking column 406 to drive the knocking column 406 to move. At this time, the knocking column 406 will contact and knock the protective cover 403, causing the protective cover 403 to vibrate, shaking off the dust and debris on the surface of the protective cover 403, improving the dustproof effect of the device and the service life of the device. The wind sensor is installed on the top of the cabinet 1 and is connected to the electric telescopic rod 401 through a wire.

[0020] Working principle: When the device is used outdoors and the outdoor is in strong wind weather, the electric telescopic rod 401 will receive the signal from the wind sensor and start. The telescopic end of the electric telescopic rod 401 will drive the connecting plate 402 to move. After the connecting plate 402 finishes moving, the connecting plate 402 can block the ventilation openings on the surface of the dust-proof cover 8 from the outside to a certain extent, avoiding excessive dust and debris being driven by the strong wind to contact the dust-proof cover 8 in strong wind weather, increasing the cleaning difficulty at the ventilation openings of the dust-proof cover 8, improving the comprehensiveness of the device when used outdoors. At the same time, during the movement of the connecting column 304, the connecting column 304 will drive the push plate 404 to move upward. During the movement of the push plate 404, the push plate 404 will contact and squeeze the knocking column 406 to drive the knocking column 406 to move. At this time, the knocking column 406 will contact and knock the protective cover 403, causing the protective cover 403 to vibrate, shaking off the dust and debris on the surface of the protective cover 403, improving the dust-proof effect of the device and extending the service life of the device.
