[0003] In the actual application in an indoor environment, in order to prevent indoor dust from entering the cabinet body along with the heat dissipation air flow, a filter screen is usually set at the air inlet; however, dust will gradually accumulate on the filter screen during long-term use, resulting in a decrease in ventilation efficiency: the dust blocks the pores of the filter screen, increasing the air flow resistance, and the heat dissipation effect significantly decays with the use time; this makes it necessary to frequently disassemble, clean or replace the filter screen during daily use, especially in a dust-intensive environment, where the manual maintenance workload is large and it is easy to cause shutdown; moreover, the accumulated dust may be carried into the cabinet body and adhere to the surface of the components, increasing the risk of electrostatic adsorption, affecting heat dissipation and even causing a short circuit.

[0014] (III) Beneficial effects The present invention provides a ventilation and dust-proof power distribution cabinet with a heat dissipation function, having the following beneficial effects: (I) For this power distribution cabinet, when the motor drives the first conveyor belt to drive the upper third rotating rod to rotate clockwise by setting a driving device, the second conveyor belt drives the lower third rotating rod to rotate counterclockwise through the meshing transmission of the first rotating rod, the first gear and the second gear, so that the upper and lower side fan blades form a convection mode of clockwise exhaust air on the upper side and counterclockwise intake air on the lower side, or counterclockwise intake air on the upper side and clockwise exhaust air on the lower side; this mode enables the two fan blades on the upper and lower sides to drive the air flow to form a directional flow channel through rotation: one side inhales external cold air through the filter screen, and the other side discharges the hot air in the cabinet, forming an exchange air flow and improving the heat dissipation effect.

[0015] (II) For this power distribution cabinet, by setting a cleaning component, when the driving device is started and the third rotating rod on the upper side of the power distribution cabinet body rotates clockwise, the extension rod fixedly connected to the third rotating rod rotates with the third rotating rod and drives the limiting component to turn over. The limiting component drives the limiting ring to rotate and drives the housing to rotate through the connecting ring. When the housing rotates, it drives the roller brush to rotate through the rotating shaft, and the roller brush cleans the filter screen. The dust cleaned out is blown to the outside of the power distribution cabinet body under the action of the wind generated by the rotating fan blades, completing the cleaning operation.

[0016] (III) By setting a limiting component, when the limiting component turns over clockwise, the connecting sleeve turns over accordingly. When the clamping block in the connecting sleeve moves to the limiting groove, the clamping block is snapped into the limiting groove under the elastic force of the spring and abuts against the vertical side wall on the side close to the clockwise direction of the limiting groove, thereby driving the limiting ring to rotate through the limiting groove and driving the housing, the rotating shaft and the roller brush to rotate through the connecting ring, so that the roller brush cleans the filter screen; at the same time, the limiting component realizes overload protection through centrifugal force. When the rotation speed of the third rotating rod increases and the centrifugal force received by the clamping block is greater than the elastic force of the spring, it will overcome the elastic force and disengage from the limiting groove, and the clamping connection with the limiting ring fails. At this time, the third rotating rod only drives the fan blades to rotate, and the limiting ring and the roller brush stop rotating due to the loss of driving force, and the cleaning function pauses, which can reduce mechanical damages such as the breakage of the brush bristles, bearing overload or splashing and overheating caused by high-speed rotation of the roller brush due to excessive rotation speed.

[0017] (4) By setting up a flipping component, when the third rotating rod drives the extension rod to rotate clockwise, the clamping block can drive the limiting ring to rotate through the limiting groove, and drive the housing to rotate through the connecting ring. When the housing rotates, it drives the roller brush and the third gear to rotate through the rotating shaft. Since the third gear meshes with the end face gear, it will force the third gear to rotate along the tooth surface of the end face gear while rotating around its own axis, and then drive the roller brush to form a compound motion of self-rotation and revolution through the rotating shaft. The self-rotation of the roller brush can roll-brush the fine structure of the filter screen, improving the cleaning effect.

[0018] (5) By setting up a dust suction component, when the fan blade rotates clockwise and the cleaning component is cleaning, the opening at the top of the U-shaped frame is facing the exhaust direction of the fan blade, forming a dust collection area. The U-shaped frame and the cover body form a dust collection cavity that can be quickly opened or closed through the clamping component. The internal electrostatic dust suction paper uses an electrostatic field to adsorb the dust in the exhaust air flow, intercept the dust brushed off the surface of the filter screen, making it difficult to spread outside the power distribution cabinet or be inhaled into the air inlet again, thus achieving the dust collection effect.

Detailed implementation mode

[0021] 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.

[0022] Embodiment 1: Please refer to Figure 1 - Figure 5 , the present invention provides a technical solution: a ventilation and dust-proof power distribution cabinet with a heat dissipation function, including the main body 10 of the power distribution cabinet. Filter screens 11 are fixedly connected to both the upper and lower sides of the side wall of the main body 10 of the power distribution cabinet, and a driving device 20 is fixedly connected to the side wall of the main body 10 of the power distribution cabinet; Ventilation assemblies 30 are fixedly connected to both the upper and lower sides of the side wall of the main body 10 of the power distribution cabinet. The ventilation assembly 30 includes a third rotating rod 31. A connecting frame 12 is fixedly connected to the inner wall of the main body 10 of the power distribution cabinet. The outer wall of the third rotating rod 31 is rotatably connected to the inner wall of the connecting frame 12. A fan blade 32 is fixedly connected to the side wall of the third rotating rod 31; The fan blade 32 is fixed to the end of the third rotating rod 31. When rotating, it generates an air flow. When rotating clockwise, the hot air in the cabinet is discharged through the filter screen 11 to form exhaust heat dissipation; When rotating counterclockwise, the external cold air is inhaled, filtered, and then injected into the cabinet to achieve intake air cooling for heat dissipation.

[0023] The driving device 20 includes a motor 21. The side wall of the motor 21 is fixedly connected to the outer wall of the power distribution cabinet body 10. The output end of the motor 21 penetrates through the side wall of the power distribution cabinet body 10 and is rotatably connected to a first conveyor belt 22 and a second conveyor belt 23. The side wall of the third rotating rod 31 on the upper side of the power distribution cabinet body 10 is rotatably connected to the inner wall of the first conveyor belt 22. The inner wall of the second conveyor belt 23 is rotatably connected to a conveying assembly 24. The side wall of the third rotating rod 31 on the lower side of the power distribution cabinet body 10 is rotatably connected to the conveying assembly 24. The output end of the motor 21 is connected to the third rotating rods 31 on the upper and lower sides of the power distribution cabinet body 10 through the first conveyor belt 22, the second conveyor belt 23 and the conveying assembly 24 respectively. This design enables the motor 21 to drive the two third rotating rods 31 to rotate simultaneously, realizing the synchronous operation of heat dissipation on the upper and lower sides of the power distribution cabinet body 10.

[0024] The conveying assembly 24 includes a first rotating rod 241. The side wall of the first rotating rod 241 is rotatably connected to the inner wall of the power distribution cabinet body 10. The side wall of the first rotating rod 241 is rotatably connected to the inner wall of the second conveyor belt 23. The inner wall of the power distribution cabinet body 10 is rotatably connected to a second rotating rod 242. The side wall of the first rotating rod 241 is fixedly connected to a first gear 243. The side wall of the second rotating rod 242 is fixedly connected to a second gear 244. The first gear 243 meshes with the second gear 244. A third conveyor belt 245 is rotatably connected to the second rotating rod 242. The side wall of the third rotating rod 31 on the lower side of the power distribution cabinet body 10 is rotatably connected to the inner wall of the third conveyor belt 245. The conveying assembly 24 plays a role in power transmission and conversion. When the motor 21 drives the first conveyor belt 22 to drive the upper third rotating rod 31 to rotate clockwise, the second conveyor belt 23 drives the lower third rotating rod 31 to rotate counterclockwise through the meshing transmission of the first rotating rod 241, the first gear 243 and the second gear 244, and then through the third conveyor belt 245, so that the upper and lower fan blades 32 form a convection mode of clockwise exhaust air on the upper side and counterclockwise intake air on the lower side or counterclockwise intake air on the upper side and clockwise exhaust air on the lower side. This mode enables the two fan blades 32 on the upper and lower sides to drive the air flow to form a directional flow channel through rotation. One side inhales external cold air through the filter screen 11, and the other side discharges the hot air in the cabinet, forming an exchange air flow and improving the heat dissipation effect.

[0025] Embodiment 2: Please refer to Figure 1 - Figure 11, the present invention provides a technical solution: on the basis of Embodiment 1, a cleaning assembly 40 is rotatably connected to the inner wall of the filter screen 11. The cleaning assembly 40 includes a housing 41, the outer wall of the housing 41 is rotatably connected to the inner wall of the filter screen 11, a connecting ring 42 is fixedly connected to the inner wall of the housing 41, a limiting ring 43 is fixedly connected to the side wall of the connecting ring 42, limiting grooves 431 are symmetrically opened on the outer wall of the limiting ring 43, an extension rod 44 is fixedly connected to the end of the third rotating rod 31 close to the housing 41, limiting components 45 are symmetrically fixedly connected to the side wall of the extension rod 44, a rotating shaft 46 is rotatably connected to the outer wall of the housing 41, and a roller brush 47 is fixedly connected to the outer wall of the rotating shaft 46; the limiting component 45 includes a connecting sleeve 451, the side wall of the connecting sleeve 451 is fixedly connected to the side wall of the third rotating rod 31, a clamping block 453 is slidably connected to the side wall of the connecting sleeve 451 through a first sliding groove 452 opened, a first spring 454 is fixedly connected to the side wall of the clamping block 453, and the end of the first spring 454 away from the clamping block 453 is fixedly connected to the inner wall of the first sliding groove 452.During use, start the driving device 20, rotate the third rotating rod 31 on the upper side of the power distribution cabinet body 10 clockwise, so that the fan blade 32 rotates clockwise, and discharge the hot air generated in the power distribution cabinet body 10 through the filter screen 11 to achieve the purpose of heat dissipation; the extension rod 44 fixedly connected to the third rotating rod 31 rotates with the third rotating rod 31 and drives the connecting sleeve 451 to turn over. When the clamping block 453 in the connecting sleeve 451 moves to the limiting groove 431, the clamping block 453 is snapped into the limiting groove 431 under the elastic force of the first spring 454 and abuts against the side wall of the limiting groove 431 on the side close to the clockwise direction. This side wall is perpendicular to the moving direction of the clamping block 453, so that the clamping block 453 can drive the limiting ring 43 to rotate through the limiting groove 431 and drive the housing 41 to rotate through the connecting ring 42. When the housing 41 rotates, it drives the roller brush 47 to rotate through the rotating shaft 46. The roller brush 47 cleans the filter screen 11, and the dust cleaned out is blown to the outside of the power distribution cabinet body 10 under the action of the wind generated by the rotating fan blade 32; the limiting component 45 can provide overload protection for the roller brush 47 through centrifugal force. When the rotation speed of the third rotating rod 31 increases, making the centrifugal force received by the clamping block 453 greater than the elastic force of the first spring 454, the clamping block 453 will overcome the elastic force of the first spring 454 under the action of the centrifugal force and disengage from the limiting groove 431, and the clamping connection with the limiting ring 43 fails. At this time, the third rotating rod 31 can only drive the rotation of the fan blade 32, and it is difficult for the limiting ring 43 and the roller brush 47 to rotate due to the loss of driving force, and the cleaning function is suspended, which can reduce mechanical damage to the roller brush 47 caused by too high a rotation speed, such as bristle breakage, bearing overload, or splashing and overheating problems caused by high-speed rotation; rotate the third rotating rod 31 on the upper side of the power distribution cabinet body 10 counterclockwise, so that the fan blade 32 rotates counterclockwise, and the external cold air enters the cabinet interior after being filtered by the filter screen 11 of the power distribution cabinet body 10 for heat dissipation. The extension rod 44 drives the connecting sleeve 451 and the clamping block 453 to rotate counterclockwise. When the clamping block 453 in the connecting sleeve 451 moves to the limiting groove 431, the clamping block 453 is snapped into the limiting groove 431 under the elastic force of the first spring 454 and abuts against the side wall of the limiting groove 431 on the side close to the counterclockwise direction. The side wall of the limiting groove 431 on the side close to the counterclockwise direction is inclined, and the range of the inclination angle is from 45 degrees to 60 degrees, so that the clamping block 453 disengages from the limiting groove 431 under the action of the inclined plane, and the clamping connection between the clamping block 453 and the limiting ring 43 fails, and the rotation amplitude of the roller brush 47 is relatively low, reducing the problem that the dust brushed off reattaches to the filter screen 11 under the action of the wind of the fan blade 32 and clogs the filter screen 11 again. A turnover assembly 50 is fixedly connected to the side wall of the power distribution cabinet body 10. The turnover assembly 50 includes a third gear 51, the inner wall of the third gear 51 is fixedly connected to the outer wall of the rotating shaft 46, an installation frame 52 is fixedly connected to the outer wall of the power distribution cabinet body 10, an end face gear 53 is fixedly connected to the inner wall of the installation frame 52, and one end of the third gear 51 away from the filter screen 11 meshes with the end face gear 53; when the third rotating rod 31 drives the extension rod 44 to rotate clockwise, the clamping block 453 can drive the limit ring 43 to rotate through the limit groove 431, and drive the housing 41 to rotate through the connecting ring 42. When the housing 41 rotates, it drives the roller brush 47 and the third gear 51 to rotate through the rotating shaft 46. Since the third gear 51 meshes with the end face gear 53, it will force the third gear 51 to rotate around its own axis while rotating along the tooth surface of the end face gear 53, and then drive the roller brush 47 to form a compound motion of self-rotation and revolution through the rotating shaft 46. The self-rotation of the roller brush 47 realizes the brushing off of the dust on the surface of the filter screen 11, and the roller brush 47 revolves around the axis of the end face gear 53, so that its cleaning range covers the entire area of the filter screen 11, rather than a fixed track, avoiding local cleaning blind spots, improving the cleaning uniformity, and thus improving the cleaning effect.

[0026] The installation frame 52 includes a first installation ring 521, the side wall of one side of the first installation ring 521 is fixedly connected to the outer wall of the power distribution cabinet body 10, the side wall of the other side is fixedly connected with a connecting strip 522, the side wall of the connecting strip 522 away from the first installation ring 521 is fixedly connected with a second installation ring 523, one end of the rotating shaft 46 away from the housing 41 is rotatably connected with a slider 461, and the side walls on both sides of the slider 461 are respectively slidably connected with the side walls of the first installation ring 521 and the second installation ring 523; the side walls on both sides of the slider 461 are respectively slidably connected with the side walls of the first installation ring 521 and the second installation ring 523, providing a sliding track for the rotation of the rotating shaft 46; when the rotating shaft 46 rotates, the slider 461 slides along the side walls of the first installation ring 521 and the second installation ring 523, guiding the rotating shaft 46 to rotate along a predetermined track; this sliding guiding effect makes the rotation of the rotating shaft 46 more stable, reduces the deviation and jitter during the rotation process, and improves the stability of the equipment operation; moreover, the slider 461 will slide and fit with the connecting strip 522 during the rotation process. When dust adheres to the surface of the connecting strip 522, the first installation ring 521 and the sliding track of the first installation ring 521, the sliding of the slider 461 can scrape off the dust and throw it away from the track area by the movement inertia, making it difficult for the dust to accumulate.

[0027] A dust suction component 60 is fixedly connected to the outer wall of the power distribution cabinet body 10. The dust suction component 60 includes a U-shaped frame 61. The side wall of the U-shaped frame 61 is fixedly connected to the outer wall of the power distribution cabinet body 10. A cover body 62 is hinged to the outer wall of one side of the U-shaped frame 61, and the outer wall of the other side is fixedly connected to the side wall of the cover body 62 through a clamping component 63. An electrostatic dust suction paper 64 is fixedly connected to the inner wall of the U-shaped frame 61 through a connecting component 65, and an electrostatic dust suction paper 64 is fixedly connected to the side wall of the cover body 62 close to the U-shaped frame 61 through the connecting component 65. When the fan blade 32 rotates clockwise and the cleaning group performs cleaning, the opening at the top of the U-shaped frame 61 is directly opposite to the air exhaust direction of the fan blade 32, forming a dust collection area. The U-shaped frame 61 and the cover body 62 form a dust collection cavity that can be quickly opened or closed through the clamping component 63. The internal electrostatic dust suction paper 64 uses an electrostatic field to adsorb the dust in the exhaust air flow, intercepts the dust brushed off the filter screen 11, and makes it difficult for the dust to spread outside the power distribution cabinet body 10 or be inhaled into the air inlet again.

[0028] The clamping component 63 includes a clamping sleeve 631. The side wall of the clamping sleeve 631 is fixedly connected to the side wall of the cover body 62. A clamping block 632 is slidably connected to the inner wall of the clamping sleeve 631. A second spring 633 is fixedly connected to the side wall of the clamping block 632. The end of the second spring 633 away from the clamping block 632 is fixedly connected to the inner wall of the clamping sleeve 631. A clamping groove 634 is formed on the side wall of the U-shaped frame 61. A pull rod 635 is fixedly connected to the side wall of the clamping block 632. The end of the pull rod 635 away from the clamping block 632 penetrates through the clamping sleeve 631 and is fixedly connected to a connecting rod 636. The pull rod 635 and the clamping block 632 are rigidly connected through the connecting rod 636. When the pull rod 635 is pulled outwards, the clamping block 632 compresses the second spring 633 and disengages from the clamping groove 634 of the U-shaped frame 61. At this time, the cover body 62 can rotate freely around the hinge axis to realize the opening cover action. After the pull rod 635 is released, the elastic force of the second spring 633 pushes the clamping block 632 into the clamping groove 634 to complete automatic locking. The whole process is simple and convenient to operate, and can be completed with one hand, facilitating the quick maintenance of the equipment.

[0029] The connecting component 65 includes a first magic tape 651. The back of the first magic tape 651 is fixedly connected to the inner wall of the U-shaped frame 61, and the back of the first magic tape 651 is fixedly connected to the side wall of the cover body 62 close to the U-shaped frame 61. Second magic tapes 652 are symmetrically fixedly connected to the side wall of the electrostatic dust suction paper 64. The first magic tape 651 is adhered to the second magic tape 652. The adhesion design of the first magic tape 651 and the second magic tape 652 enables the electrostatic dust suction paper 64 to be directly pasted on the inner wall of the U-shaped frame 61 and the inner side of the cover body 62. During installation, it only needs to be aligned and pressed to be fixed. During disassembly, gently pulling the edge of the dust suction paper can separate it. The operation is simple and convenient, which is suitable for the frequent replacement of the electrostatic dust suction paper 64.

[0030] Working principle: In use, the ventilation and dust-proof power distribution cabinet with heat dissipation function mainly consists of a power distribution cabinet body 10, a driving device 20, a ventilation component 30, a cleaning component 40, a flipping component 50, and a dust suction component 60. Among them, the driving device 20 is used to drive the ventilation component 30 to perform suction and exhaust operations to dissipate heat from the power distribution cabinet body 10. The flipping component 50 cooperates with the cleaning component 40 to clean the filter screen 11 on the power distribution cabinet body 10, and the dust suction component 60 is used to collect dust from the outside and the dust brushed off.

[0031] Among them, the driving device 20 includes a motor 21, a first conveyor belt 22, a second conveyor belt 23, and a transmission component 24. The output end of the motor 21 is connected to the third rotating rod 31 on the upper and lower sides of the power distribution cabinet body 10 through the first conveyor belt 22, the second conveyor belt 23, and the transmission component 24 respectively. This design enables the motor 21 to drive the two third rotating rods 31 to rotate simultaneously and drive the two fan blades 32 to rotate, realizing the synchronous operation of heat dissipation.

[0032] The transmission component 24 includes a first rotating rod 241, a second rotating rod 242, a first gear 243, a second gear 244, and a third conveyor belt 245. When the motor 21 drives the first conveyor belt 22 to drive the upper third rotating rod 31 to rotate clockwise, the second conveyor belt 23 drives the lower third rotating rod 31 to rotate counterclockwise through the meshing transmission of the first rotating rod 241, the first gear 243, and the second gear 244, and then through the third conveyor belt 245, so that the upper and lower fan blades 32 form a convection mode of clockwise exhaust on the upper side and counterclockwise intake on the lower side, or counterclockwise intake on the upper side and clockwise exhaust on the lower side. This mode enables the two fan blades 32 on the upper and lower sides to drive the air flow to form a directional flow channel through rotation: one side inhales external cold air through the filter screen 11, and the other side discharges the hot air in the cabinet, forming an exchange air flow and improving the heat dissipation effect.

[0033] The ventilation component 30 includes a third rotating rod 31 and a fan blade 32. The fan blade 32 is fixed to the end of the third rotating rod 31 and generates an air flow through rotation. When rotating clockwise, it discharges the hot air in the cabinet through the filter screen 11 to form exhaust heat dissipation. When rotating counterclockwise, it inhales external cold air, filters it, and injects it into the cabinet to achieve intake air cooling for heat dissipation.

[0034] The cleaning component 40 includes a housing 41, a connecting ring 42, a limiting ring 43, an extension rod 44, a limiting component 45, a rotating shaft 46, and a drum brush 47; when the driving device 20 is started, the third rotating rod 31 on the upper side of the power distribution cabinet body 10 is rotated clockwise, and the extension rod 44 fixedly connected to the third rotating rod 31 rotates following the third rotating rod 31 and drives the limiting component 45 to flip. The limiting component 45 drives the limiting ring 43 to rotate, and drives the housing 41 to rotate through the connecting ring 42. When the housing 41 rotates, it drives the drum brush 47 to rotate through the rotating shaft 46, and the drum brush 47 cleans the filter screen 11. The dust cleaned out is blown to the outside of the power distribution cabinet body 10 under the action of the wind generated by the rotating fan blades 32, completing the cleaning operation.

[0035] The limiting component 45 includes a connecting sleeve 451, a clamping block 453, and a first spring 454. When the limiting component 45 rotates clockwise, the connecting sleeve 451 rotates. When the clamping block 453 in the connecting sleeve 451 moves to the limiting groove 431, the clamping block 453 is snapped into the limiting groove 431 under the elastic force of the first spring 454 and abuts against the side wall of the limiting groove 431 on the side closer to the clockwise direction. This side wall is perpendicular to the moving direction of the clamping block 453, enabling the clamping block 453 to drive the limiting ring 43 to rotate through the limiting groove 431, and drive the housing 41, the rotating shaft 46, and the drum brush 47 to rotate through the connecting ring 42, so that the drum brush 47 cleans the filter screen 11. Moreover, the limiting component 45 can provide overload protection for the drum brush 47 through centrifugal force. When the rotation speed of the third rotating rod 31 increases, causing the centrifugal force acting on the clamping block 453 to be greater than the elastic force of the first spring 454, the clamping block 453 will overcome the elastic force of the first spring 454 under the action of the centrifugal force and disengage from the limiting groove 431, resulting in the failure of the clamping connection between the clamping block 453 and the limiting ring 43. At this time, the third rotating rod 31 can only drive the rotation of the fan blade 32, and it is difficult for the limiting ring 43 and the drum brush 47 to rotate due to the loss of driving force, and the cleaning function pauses, which can reduce mechanical damage to the drum brush 47 caused by excessive rotation speed, such as bristle breakage, bearing overload, or problems such as splashing and overheating caused by high-speed rotation. Rotate the third rotating rod 31 on the upper side of the power distribution cabinet body 10 counterclockwise to make the fan blade 32 rotate counterclockwise. The external cold air enters the cabinet interior after being filtered by the filter screen 11 of the power distribution cabinet body 10 for heat dissipation. The extension rod 44 drives the connecting sleeve 451 and the clamping block 453 to rotate counterclockwise. When the clamping block 453 in the connecting sleeve 451 moves to the limiting groove 431, the clamping block 453 is snapped into the limiting groove 431 under the elastic force of the first spring 454 and abuts against the side wall of the limiting groove 431 on the side closer to the counterclockwise direction. The side wall of the limiting groove 431 on the side closer to the counterclockwise direction is inclined, and the range of the inclination angle is from 45 degrees to 60 degrees, enabling the clamping block 453 to disengage from the limiting groove 431 under the action of the inclined plane, resulting in the failure of the clamping connection between the clamping block 453 and the limiting ring 43, and the rotation amplitude of the drum brush 47 is relatively low, reducing the problem that the dust brushed off is reattached to the filter screen 11 under the action of the wind force of the fan blade 32 and blocking the filter screen 11 again.

[0036] The flipping assembly 50 includes a third gear 51, a mounting bracket 52, and an end face gear 53. When the third rotating rod 31 drives the extension rod 44 to rotate clockwise, the clamping block 453 can drive the limiting ring 43 to rotate through the limiting groove 431, and drive the housing 41 to rotate through the connecting ring 42. When the housing 41 rotates, it drives the drum brush 47 and the third gear 51 to rotate through the rotating shaft 46. Since the third gear 51 meshes with the end face gear 53, it will force the third gear 51 to rotate around its own axis while rotating along the tooth surface of the end face gear 53. Then, through the rotating shaft 46, the drum brush 47 forms a compound motion of self-rotation and revolution. The self-rotation of the drum brush 47 realizes the brushing off of the dust on the surface of the filter screen 11. The drum brush 47 revolves around the axis of the end face gear 53, so that its cleaning range covers the entire area of the filter screen 11, rather than a fixed trajectory, avoiding local cleaning blind spots and improving the cleaning uniformity, thereby improving the cleaning effect.

[0037] The mounting bracket 52 includes a first mounting ring 521, a connecting strip 522, and a second mounting ring 523. The side walls on both sides of the slider 461 are respectively slidably connected to the side walls of the first mounting ring 521 and the second mounting ring 523, providing a sliding track for the rotation of the rotating shaft 46. When the rotating shaft 46 rotates, the slider 461 slides along the side walls of the first mounting ring 521 and the second mounting ring 523, guiding the rotating shaft 46 to rotate along a predetermined trajectory, making the rotation of the rotating shaft 46 more stable. Moreover, the slider 461 will slidably fit with the connecting strip 522 during the rotation. When dust adheres to the surface of the connecting strip 522, the sliding tracks of the first mounting ring 521 and the first mounting ring 521, the sliding of the slider 461 can scrape off the dust and throw it away from the track area by inertial motion, making it difficult for the dust to accumulate.

[0038] The dust suction assembly 60 includes a U-shaped frame 61, a cover body 62, a clamping assembly 63, an electrostatic dust suction paper 64, and a connecting assembly 65. When the fan blade 32 rotates clockwise and the cleaning group conducts cleaning, the opening at the top of the U-shaped frame 61 faces the exhaust direction of the fan blade 32, forming a dust collection area. The U-shaped frame 61 and the cover body 62 form a dust collection cavity that can be quickly opened or closed through the clamping assembly 63. Inside is the electrostatic dust suction paper 64, which uses an electrostatic field to adsorb the dust in the air flow, intercepts the dust brushed off from the filter screen 11, making it difficult for the dust to spread outside the power distribution cabinet body 10 or be inhaled into the air inlet again, achieving the effect of collecting dust.

[0039] The snap - connection component 63 includes a snap - sleeve 631, a snap - block 632, a second spring 633, a card slot 634, a pull rod 635, and a connecting rod 636; when the pull rod 635 is pulled outwards, the snap - block 632 compresses the second spring 633 and disengages from the card slot 634 of the U - shaped frame 61. At this time, the cover 62 can rotate freely around the hinge axis to achieve the opening - cover action; after the pull rod 635 is released, the elastic force of the second spring 633 pushes the snap - block 632 into the card slot 634 to complete automatic locking; the whole process is simple and convenient to operate, and can be completed with one hand, facilitating the quick maintenance of the device.

[0040] The connection component 65 includes a first magic tape 651 and a second magic tape 652; the adhesion design of the first magic tape 651 and the second magic tape 652 enables the electrostatic dust - absorbing paper 64 to be directly pasted on the inner wall of the U - shaped frame 61 and the inner side of the cover 62. During installation, it only needs to be aligned and pressed to be fixed, and during disassembly, it can be separated by gently pulling the edge of the dust - absorbing paper. The operation is simple and convenient, which is suitable for the frequent replacement of the electrostatic dust - absorbing paper 64.
