[0031] The bottom surface of the distribution box housing 100 is connected to the mobile heat dissipation mechanism 400 through the first screw rod 703 and the second screw rod 704 in the starting mechanism 700. A plurality of fans 402 are arranged on the mobile heat dissipation mechanism 400 to remove dust and dissipate heat for the electrical components 300. At the same time, the bottom surface of the mobile heat dissipation mechanism 400 is connected to the dust removal mechanism 600. The mobile heat dissipation mechanism 400 is placed above the starting mechanism 700, and the dust removal mechanism 600 is placed below the starting mechanism 700.

[0032] The first screw rod 703 and the second screw rod 704 have the same thread pitch and the same thread direction; the first screw rod 703 and the second screw rod 704 are both provided with a movable heat dissipation mechanism 400;

[0033] When the electrical device 300 is powered on, the mobile heat dissipation mechanism 400 and the dust removal mechanism 600 are repeatedly moved along the first screw rod 703 and the second screw rod 704 in the area of ​​the electrical device 300. When it is necessary to clean the bottom surface of the distribution box casing after the electrical device 300 is powered off, the mobile heat dissipation mechanism 400 and the dust removal mechanism 600 are repeatedly moved along the first screw rod 703 and the second screw rod 704 in the bottom area of ​​the distribution box casing 100. The area of ​​the electrical device 300 is smaller than the area of ​​the distribution box casing 100.

[0034] The side of the distribution box housing 100 is provided with a heat dissipation port 101 for heat dissipation, and a dust removal port 102 is provided below the heat dissipation port 101 .

[0035] A cabinet door 200 is also provided on the distribution box housing 100, and an arc-shaped rack 201 is provided at the lower end of the cabinet door 200. When the cabinet door 200 is opened, the arc-shaped rack 201 rotates with the cabinet door 200. During the rotation of the arc-shaped rack 201, the arc-shaped rack 201 meshes with the driven gear 202, driving the driven gear 202 to rotate. The upper end of the driven gear 202 is fixed to the inner wall of the distribution box housing 100 through the gear bracket 203. The upper end of the driven gear 202 passes through the gear bracket 203 and is connected to the first bevel gear 204.

A second limiting rod 208 is also provided on the connecting rod 207. The second limiting rod 208 passes through the connecting rod 207 and is fixed to the outer wall of the distribution box housing 100.

[0036] The mobile heat dissipation mechanism 400 includes a mobile base plate 401, and multiple fans 402 are arranged on the inner side of the mobile base plate 401, and the fans 402 are aligned with the wiring points of the electrical components 300; a mobile joint 403 is provided at the lower end of the mobile base plate 401, and a first limiting rod 404 is provided at the upper end, and both ends of the first limiting rod 404 are fixed to the inner wall of the distribution box housing 100.

[0037] Preferably, when the electrical device 300 is powered on, the movable base plate 401 moves along the first screw rod 703 and the second screw rod 704. When it moves to both sides of the electrical device 300, the side of the movable base plate 401 squeezes the side of the rectangular frame 502, the rectangular frame 502 moves, and the slats 504 clean the dust accumulated at the heat dissipation port 101. At the same time, the first squeezing block 505 turns on the first switch 506, the first motor 701 and the second motor 702 reverse at the same time, the movable base plate 401 moves in the opposite direction, and finally squeezes another dredging mechanism 500. The above actions are repeated, and the previous rectangular frame 502 is reset under the action of the spring 508.

[0038] A dredging mechanism 500 is provided on the inner side of the heat dissipation port 101, and the dredging mechanism 500 is used to clean the sand and dust at the heat dissipation port 101. The dredging mechanism 500 includes a side fixing frame 501, and the two sides of the electrical device 300 are fixed to the inner wall of the distribution box housing 100 through the side fixing frame 501. Both ends of the side fixing frame 501 are provided with a card slot 507, and a spring 508 is provided in the card slot 507. One end of the spring 508 is fixed to the inner wall of the distribution box housing 100, and the other end is connected to the protrusions on the inner side surfaces of the upper and lower ends of the rectangular frame 502. The protrusion moves in the card slot 507. The rectangular frame 502 is connected to the slats 504 through the connecting frame 503. The slats 504 correspond to the holes of the heat dissipation port 101. A first extrusion block 505 is provided on one side of the upper end of the rectangular frame 502. The first extrusion block 505 is used to start the first switch 506, and the first switch 506 is fixed on the inner wall of the distribution box housing 100.

[0039] Preferably, the fan 402, the first extrusion block 505 and the first switch 506 are connected in series with the electrical device 300. When the electrical device 300 fails to work, the fan 402, the first extrusion block 505 and the first switch 506 also stop working. The second extrusion block 603 and the second switch 604 are connected in series with the first motor 701 and the second motor 702. The first motor 701 and the second motor 702 use independent power supplies, which are not shown in the figure.

[0040] It should be noted that the movable joint 403 is connected to the dust removal mechanism 600 and the movable base plate 401 through an electromagnetic joint 602. The electromagnetic joint 602 on the dust collecting plate 601 and the first motor 701 and the second motor 702 share the same power supply. The electromagnetic joint 602 on the bottom surface of the movable base plate 401 and the electrical device 300 share the same power supply.

[0041] The dust removal mechanism 600 includes a dust collecting plate 601, both ends of which are connected to two movable joints 403 via electromagnetic joints 602. A second extrusion block 603 is provided in the middle of the dust collecting plate 601. The second extrusion block 603 is used to start the second switch 604. The second switch 604 is fixed on the inner wall of the distribution box housing 100.

[0042] Preferably, when maintenance is required, the staff cuts off the power, and the fan 402, the first extrusion block 505 and the first switch 506 stop working. At this time, the cabinet door 200 is opened until it is fully open. At this time, the dust removal port 102 is opened along the threaded rod 206, and the first extrusion block 505 and the first switch 506 lose their functions. At the same time, the movable bottom plate 401 is disengaged from the movable joint 403, and the movement area of ​​the dust collecting plate 601 is expanded. At this time, the dust collecting plate 601 moves repeatedly along the bottom surface of the distribution box casing 100. When the dust collecting plate 601 moves to both ends of the bottom surface of the distribution box casing 100, the second extrusion block 603 opens the second switch 604, the first motor 701 and the second motor 702 reverse, and the dust collecting plate 601 moves in the opposite direction. The working principle is consistent with the first extrusion block 505 and the first switch 506.

[0043] The first screw rod 703 and the second screw rod 704 are connected to the output ends of the first motor 701 and the second motor 702 respectively.

[0044] During use, when the electrical device 300 is powered on, the movable joint 403 is connected to the dust collecting plate 601 and the movable bottom plate 401 at the same time, and the fan 402 on the movable bottom plate 401 will dissipate heat for the electrical device 300. At the same time, the fan 402 will play a certain role in cleaning the dust at the connection point of the electrical device 300. When the electrical device 300 is powered on, the first extrusion block 505 and the first switch 506 are turned on first, thereby restricting the movement range of the movable bottom plate 401 to the area of ​​the electrical device 300. At the same time, the dust collecting plate 601 collects the dust on the bottom surface of the electrical device 300 area to the two ends of the bottom surface of the distribution box casing 100; when the distribution box needs to be repaired, the staff needs to first Disconnect the power supply of the electrical device 300, open the cabinet door 200, and at the same time, the dust removal port 102 is opened, the movable base plate 401 is separated from the movable joint 403, and the dust collecting plate 601 still moves with the movable joint 403. At this time, the first extrusion block 505 and the first switch 506 fail, and the second extrusion block 603 and the second switch 604 start to work. The moving range of the movable joint 403 is expanded to the area of ​​the bottom surface of the distribution box casing 100. During the movement, the dust collecting plate 601 discharges the dust gathered at both ends of the bottom surface of the distribution box casing 100 out of the box body from the dust removal port 102; the maintenance is completed, the electrical device 300 is powered on, and the movable joint 403 is connected to the movable base plate 401 during the movement, and the above operation is repeated.

[0045] In summary, during the daily operation of the distribution box, the device uses the mobile fan 402 to effectively dissipate the heat of the electrical components in the distribution box. At the same time, the fan 402 is positioned at the wiring point of the electrical components to assist in cleaning the dust adsorbed at the wiring point. At this time, the dust collecting plate 601 will collect the dust on the bottom of the distribution box. When the distribution box needs to be inspected and repaired, the fan 402 and the electrical components are powered off together, but the dust collecting plate 601 is still working. When the staff opens the door panel, the dust collecting plate 601 can automatically clean the concentrated dust out of the distribution box.
