[0030] Embodiment 1

[0031] See also Figure 1-Figure 3As shown in the figure, a housing for a low-voltage distribution box with a heat dissipation function includes a distribution box body 100, a protective device 200 is fixedly installed on the outer side of the distribution box body 100, a protective door 300 is rotatably connected to the front end of the protective device 200, and a dustproof plate 400 is installed on the top of the protective device 200;

[0032] The top of the protective device 200 is provided with a dust removal assembly 500, which includes an electric rotating rod 501, which is located at the side of the protective device 200, and is fixed between the electric rotating rod 501 and the protective device 200. The side of the electric rotating rod 501 is connected to the rotating rod 502 in a transmission manner, and the side of the rotating rod 502 is equipped with a torsion spring rod 1 503, and the outer side of the torsion spring rod 1 503 is fixedly connected to a baffle 504, and the outer side of the rotating rod 502 is fixedly connected to an extrusion rod 505. When the heat dissipation holes on the top of the protective device 200 need to be cleaned, the electric rotating rod 501 is started to rotate the rotating rod 502 connected thereto, and the rotating rod 502 then drives the torsion spring rod 1 503 and the extrusion rod 505 to rotate. The outer side of the protective device 200 is fixedly connected to a hydraulic chamber 506, and one end of the hydraulic chamber 506 is slidably connected to a force-bearing arc rod 507, and the other end of the hydraulic chamber 506 is slidably connected to a push rod 508. When the torsion spring rod 503 and the extrusion rod 505 rotate, the torsion spring rod 503 synchronously drives the baffle 504 fixedly connected thereto to rotate. When the baffles 504 on both sides rotate to a horizontal position at the heat dissipation holes on the top of the distribution box body 100, the baffle 504 is restricted by the distribution box body 100 and cannot continue to rotate. At this time, the rotating rod 502 continues to drive the extrusion rod 505 fixedly connected thereto to rotate, so that the extrusion rod 505 squeezes the stressed arc rod 507 to move, and cooperates with the hydraulic chamber 506 slidably connected to the stressed arc rod 507, so that the pressure in the hydraulic chamber 506 increases, driving the push rod 508 slidably connected to the hydraulic chamber 506 to move. A spring 509 is fixedly connected to the side of the push rod 508, one end of the spring 509 is connected to the push rod 508, and the other end of the spring 509 is connected to the inner wall of the hydraulic chamber 506. The top of the protective device 200 is rotatably connected to a torsion spring rod 510, one end of the torsion spring rod 510 is fixedly connected to a force plate 511, and the force plate 511 is located on the side of the push rod 508. The force plate 511 is in contact with the push rod 508, and the other end of the torsion spring rod 510 is equipped with a cleaning device 600. A discharge port 512 is opened on the side of the protective device 200.When the push rod 508 moves, the force-bearing plate 511 can be squeezed and moved. Since the force-bearing plate 511 is fixedly connected to the torsion spring rod 510, and the torsion spring rod 510 and the protective device 200 are in a rotational connection state, the force-bearing plate 511 can be rotated with the torsion spring rod 510 as the axis, which can drive the cleaning device 600 connected to the torsion spring rod 510 to rotate for cleaning; after the cleaning is completed, some dust enters the protective device 200 and falls on the top of the baffle 504. At this time, the electric rotating rod 501 is started to drive the rotating rod 502 to reset, so that the device is reset under the action of the torsion spring rod 1 503, the spring 509 and the torsion spring rod 510 themselves, and the reset baffle 504 is in an inclined state, and the dust on it is discharged through the discharge ports 512 on both sides of the protective device 200. During the whole process, it is difficult for dust to fall into the device, reducing the possibility of dust entering the device and affecting the operation of the device.

[0033] When in use, when the heat dissipation holes on the top of the protective device 200 need to be cleaned, the electric rotating rod 501 is started to rotate the rotating rod 502 connected thereto, and the rotating rod 502 then drives the torsion spring rod 1 503 and the extrusion rod 505 to rotate. At this time, the torsion spring rod 1 503 synchronously drives the baffle 504 fixedly connected thereto to rotate. When the baffles 504 on both sides rotate to the horizontal position at the heat dissipation holes on the top of the distribution box body 100, the baffle 504 is restricted by the distribution box body 100 and cannot continue to rotate. At this time, the rotating rod 502 continues to drive the extrusion rod 505 fixedly connected thereto to rotate, so that the extrusion rod 505 squeezes the stressed arc rod 507 to move, and cooperates with the hydraulic chamber 506 slidably connected to the stressed arc rod 507, so that the pressure in the hydraulic chamber 506 increases, driving the push rod slidably connected to the hydraulic chamber 506 508 moves, and the push rod 508 squeezes the force-bearing plate 511 and moves it. Since the force-bearing plate 511 is fixedly connected to the torsion spring rod 510, and the torsion spring rod 510 and the protective device 200 are in a rotational connection state, the force-bearing plate 511 rotates with the torsion spring rod 510 as the axis, which can drive the cleaning device 600 connected to the torsion spring rod 510 to rotate for cleaning; after the cleaning is completed, some dust enters the protective device 200 and falls on the top of the baffle 504. At this time, the electric rotating rod 501 is started to drive the rotating rod 502 to reset, so that the device is reset under the action of the torsion spring rod 1 503, the spring 509 and the torsion spring rod 510 themselves, and the reset baffle 504 is in a tilted state, and the dust on it is discharged through the discharge ports 512 on both sides of the protective device 200.

[0034] To improve the usability of the device, please refer to Figure 1-Figure 4As shown in the figure, the cleaning device 600 includes a fixed block 601, a cleaning brush 602 and a limiting top plate 603. A penetrating "T"-shaped groove is opened between the fixed blocks 601, and the cleaning brush 602 is in a "T" shape. The side of the fixed block 601 is rotatably connected to the limiting plate 605 by setting a torsion spring rod 604. When the cleaning brush 602 on the cleaning device 600 accumulates dust due to long-term use, the limiting plate 605 is rotated so that the limiting plate 605 rotates around the torsion spring rod three 604 as the axis, thereby opening the groove between the fixed blocks 601, and then the limiting top plate 603 and the cleaning brush 602 can be pulled out to clean or replace the cleaning brush 602; the clean cleaning brush 602 and the limiting top plate 603 are inserted into the groove between the fixed blocks 601, and the limiting plate 605 is loosened, so that the limiting plate 605 is rotated to the side opening of the fixed block 601 under the action of the torsion spring rod three 604, the groove is closed, and the cleaning or replacement of the cleaning brush 602 is completed, thereby further improving the cleaning effect and making the device easier to use.

[0035] During use, when the cleaning brush 602 on the cleaning device 600 accumulates dust due to long-term use, the limiting plate 605 is rotated so that the limiting plate 605 rotates around the torsion spring rod three 604 as the axis, thereby opening the groove between the fixed blocks 601, and then the limiting top plate 603 and the cleaning brush 602 can be pulled out to clean or replace the cleaning brush 602; the clean cleaning brush 602 and the limiting top plate 603 are inserted into the groove between the fixed blocks 601, and the limiting plate 605 is loosened, so that the limiting plate 605 is rotated to the side opening of the fixed block 601 under the action of the torsion spring rod three 604 to close the groove.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
