[0030] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below with reference to specific diagrams. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0031] See also Figure 1 - Figure 7 The embodiment of the present invention provides a technical solution: an electrical switch cabinet with a dust removal structure, comprising a switch cabinet body 1, a plurality of air guide sleeves 11 distributed in a rectangular array are fixedly installed on both sides of the inner wall of the switch cabinet body 1, a first valve 15 is fixedly installed on the inner side of the air guide sleeve 11, a filter screen 12 is fixedly installed in each air guide sleeve 11, a driving motor 13 and a fan blade 14 are respectively arranged on the inner and outer sides of each filter screen 12, a first rotating cylinder 2 is rotatably installed in the air guide sleeve 11, the rear end of the first rotating cylinder 2 is connected to the output shaft of the driving motor 13, a second rotating cylinder 23 is plugged and installed in the middle of the fan blade 14, the second rotating cylinder 23 is rotatably installed at the front end of the first rotating cylinder 2, and the inner cavities of the two are connected. The two parts are interconnected, and a movable frame 20 is fixedly installed on the periphery of the first rotating cylinder 2. The rear end of the movable frame 20 fits with the front end of the filter screen 12. A dust guide groove 21 is provided on the rear end of the movable frame 20. The dust guide groove 21 is communicated with the inner cavity of the first rotating cylinder 2. A dust guide frame 25 is fixedly installed in the air guide sleeve 11 through a dust guide pipe 27. Dust guide cavities 26 are provided between adjacent dust guide pipes 27 and between the rear dust guide pipe 27 and the rear end of the switch cabinet body 1. A second valve 28 connected to the dust guide cavity 26 is fixedly installed on the rear side of the outer wall of the switch cabinet body 1. The second rotating cylinder 23 is rotatably installed in the dust guide frame 25, and a dust guide hole 24 communicated with the inner cavity of the dust guide frame 25 is provided on the periphery of the second rotating cylinder 23.

[0032] Working principle: When in use, the drive motor 13 is started, and the fan blades 14 can be driven to rotate through its output shaft. The fan blades 14 on both sides can guide the outside air into the switch cabinet body 1, and the air inside the switch cabinet body 1 is discharged to the outside, so as to achieve the effect of heat dissipation inside the switch cabinet body 1, and the dust in the air can be filtered when the air enters the switch cabinet body 1 through the filter screen 12;

[0033] When it is necessary to clean the dust on the surface of the filter 12, close the first valve 15 at the air guide sleeve 11. At this time, since the air flow path inside the air guide sleeve 11 is changed, and since the driving motor 13 drives the movable frame 20 to rotate at the front end of the filter 12 through its output shaft, the dust on the surface of the filter 12 can be pushed into the dust guide groove 21 through the air pressure difference at the joint of the two, and then the dust can be discharged outward through the first rotating cylinder 2, the second rotating cylinder 23, the dust guide hole 24, the dust guide frame 25, the dust guide pipe 27 and the dust guide cavity 26, so as to achieve the effect of dust recovery.

[0034] In another embodiment provided by the present invention, each movable frame 20 is provided with a symmetrically arranged bracket 4 on the rear side, the inner side of the bracket 4 is fixedly connected to the outer periphery of the first rotating cylinder 2, and a tooth plate 42 is slidably installed in the inner cavity of each bracket 4, and a cleaning brush 43 that fits with the rear side of the filter screen 12 is fixedly installed on the front side of the tooth plate 42; a first gear B44 and a first gear A47 are rotatably installed in the middle and outer sides between two adjacent brackets 4, and the first gear B44 is meshingly connected between the two tooth plates 42; a movable plate 45 is fixedly installed on the outer end of one side tooth plate 42, and a limiting slide groove 46 is provided in the middle part of the movable plate 45, and a sliding rod 48 slidably connected to the limiting slide groove 46 is fixedly installed on the outer periphery of the front end of the first gear A47, and a first gear ring 49 is fixedly installed on the inner wall of the air guide sleeve 11, and the outer periphery of the first gear A47 is meshingly connected with the first gear ring 49.

[0035] Specifically, when the driving motor 13 drives the movable frame 20 to rotate through its output shaft, the bracket 4 can be driven to rotate at the rear end of the filter 12, and the rotating bracket 4 can drive the first gear A47 to rotate through the meshing connection between the first gear A47 and the first gear ring 49. The rotating first gear A47 can drive the two cleaning brushes 43 to reciprocate between the two brackets 4 through the sliding connection between the slide rod 48 and the limiting slide groove 46 and the connection between the two tooth plates 42 and the first gear B44, so as to push the dust at the front end of the filter 12 forward at the rear side of the filter 12, thereby improving the dust removal effect.

[0036] In another embodiment provided by the present invention, a limit plate 3 is fixedly installed at the rear end of the dust guide frame 25, a second gear 32 is rotatably installed at the rear end of the limit plate 3, an inner gear ring 31 is fixedly installed on the outer periphery of the rear end of the second rotating cylinder 23, an outer gear ring 33 is fixedly installed at the front end of the first rotating cylinder 2, and the second gear 32 is meshingly connected between the outer gear ring 33 and the inner gear ring 31.

[0037] Through the meshing connection between the second gear 32 and the outer gear ring 33 and the inner gear ring 31, the transmission ratio between the fan blades 14 and the movable frame 20 can be reduced. When the fan blades 14 rotate at high speed, the movable frame 20 can be maintained in a low-speed rotation state, thereby ensuring the dust removal effect of the device.

[0038] In another embodiment provided by the present invention, an electric push rod 5 is fixedly installed on the front side of the inner cavity of the switch cabinet body 1, and a rotating seat 51 is fixedly installed on the rear end of the electric push rod 5 through its output shaft. The front end of the fan blade 14 is rotatably connected to the rear end of the rotating seat 51, and a movable sleeve 54 is fixedly installed on the rear end of the fan blade 14. A driving rod 50 is fixedly installed on the front end of the driving motor 13 through its output shaft, and the driving rod 50 is plugged and installed in the middle of the movable sleeve 54; a tooth block 53 is fixedly installed on the front side of the outer periphery of the movable sleeve 54, and a tooth groove 52 is provided at the front end of the second rotating cylinder 23, and the tooth block 53 is plugged and installed in the tooth groove 52; a through cavity 57 is provided on the inner wall of the air guide sleeve 11, and a through hole 58 is provided between the through cavity 57 and the dust guide cavity 26, and a sealing ring 56 is slidably installed on the inner wall of the air guide sleeve 11, and the sealing ring 56 and the through cavity 57 are in contact with each other, and a rotating ring 55 is fixedly installed on the middle part of the sealing ring 56 through a connecting rod, and the rotating ring 55 is rotatably installed on the rear side of the outer periphery of the movable sleeve 54.

[0039] Specifically, when the switch cabinet body 1 is ventilated and cooled, the first valve 15 is opened, the second valve 28 is closed, and the electric push rod 5 is started. Through its output shaft and the rotating seat 51, the movable sleeve 54 is driven to move forward, so that the tooth block 53 and the tooth groove 52 are separated from each other. At this time, the driving motor 13 is started, and through its output shaft and the driving rod 50, the movable sleeve 54 and the outer fan blades 14 of the movable sleeve 54 can be driven to rotate, so as to achieve the effect of cooling the switch cabinet body 1. Since the tooth block 53 and the tooth groove 52 are separated from each other, the rotating movable sleeve 54 will not drive the movable frame 20 to rotate, so that the movable frame 20 is in a stationary state, thereby ensuring the air circulation effect on the surface of the filter screen 12;

[0040] When it is necessary to clean the dust on the surface of the filter 12, the first valve 15 is closed, the second valve 28 is opened, and the electric push rod 5 is started. Through its output shaft and the rotating seat 51, the movable sleeve 54 is driven to move backward, so that the tooth block 53 and the tooth groove 52 are re-inserted. At this time, while the driving motor 13 drives the movable sleeve 54 and the outer fan blades 14 of the movable sleeve 54 to rotate through its output shaft and the driving rod 50, it can also drive the movable frame 20 and the bracket 4 to rotate at the front and rear sides of the filter 12 respectively, so as to achieve the effect of cleaning the dust on the surface of the filter 12;

[0041] In addition, when the cleaning brush 43 contacts the filter 12, the aperture of the filter 12 will change slightly, so that part of the dust at the front end will pass through the filter 12 and enter the back side of the filter 12. To clean the dust, the first valve 15 can be closed and the second valve 28 can be opened. The electric push rod 5 can be used to drive the tooth block 53 and the tooth groove 52 to separate from each other. At this time, the sealing ring 56 and the through cavity 57 are misaligned with each other. The drive motor 13 is started, and the outside air can be guided into the air guide sleeve 11 through the rotating fan blades 14. The dust on the back side of the filter 12 can be guided into the dust guide cavity 26 through the through cavity 57 and the through hole 58, so as to achieve the effect of recycling the dust.

[0042] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and the description in the specification are only to illustrate the principles of the present invention.
