[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figure 1-5 As shown, a self-cleaning device for a distribution box includes a housing 11, with a connecting seat 12 on the side of the housing 11; a cleaning groove is provided at the bottom of the housing 11; an air outlet groove 22 is provided at the corresponding position on the side of the housing 11 and the connecting seat 12; an air inlet groove 21 is provided at the top of the housing 11; a roller 13 is rotatably connected inside the housing 11; a cavity is provided inside the roller 13; a through groove 24 and a filter groove 23 are provided on the side of the cavity; a filter plate 14 is installed inside the filter groove 23; a cleaning box 15 is fixedly connected to the bottom of the cleaning groove; a brush roller 16 is installed inside the cleaning box 15; a first motor 17 is fixedly connected to the side of the housing 11; and the output end of the first motor 17 is fixedly connected to the roller 13.

[0024] In use, the connecting seat 12 is installed at the air inlet of the distribution cabinet. The air inlet of the distribution cabinet is connected to the air outlet 22 through the connecting seat 12. During cleaning, the first motor 17 is started periodically, and the roller 13 can rotate inside the housing 11. The through groove 24 on the roller 13 is aligned with the air outlet 22, and the air inlet 21 is aligned with the filter groove 23. Then, during the heat dissipation process of the distribution box fan, the air is filtered through the filter plate 14 in its filter groove 23 and enters the air inlet of the distribution box through the cavity and the air outlet 22. When cleaning is required, the first motor 17 drives the roller 13 to rotate, so that the filter plate 14 and the cleaning groove are aligned. During the rotation of the roller 13, the filter plate 14 and the brush roller 16 come into contact and rub against each other, thereby cleaning the filter plate 14 and achieving self-cleaning of the filter plate 14. This makes it convenient for staff to use and saves time and effort. The first motor 17 is a servo motor.

[0025] Furthermore, such as Figure 1-5 As shown, there are two of each of the cavity, through groove 24, filter plate 14 and filter tank 23, with the two filter tanks 23 located at the top and bottom of the roller 13, respectively.

[0026] By setting up two cavities, a filter tank 23, a through groove 24, and a filter plate 14, one of them is used for air filtration and the other is used for cleaning and dust removal from the filter plate 14, which is convenient to use. This switchable method can reduce the amount of dust generated during the cleaning of the filter plate 14 being sucked into the power distribution cabinet by the fan during the air intake process.

[0027] Furthermore, such as Figure 1-5 As shown, the brush roller 16 and the inner wall of the cleaning box 15 are rotatably connected. A second motor 3 is fixedly connected to the side wall of the cleaning box 15, and the output end of the second motor 3 is fixedly connected to the brush roller 16. An exhaust port 41 is provided on the side of the cleaning box 15 at the corresponding position of the brush roller 16. A fan blade 42 is fixedly connected to the end of the brush roller 16 away from the second motor 3, and the fan blade 42 is located inside the exhaust port 41.

[0028] In use, the brush roller 16 and the cleaning box 15 are rotatably connected, and the brush roller 16 is driven to rotate by the second motor 3, which can improve the cleaning effect of the brush roller 16 on the filter plate 14. The end of the brush roller 16 is equipped with a fan blade 42. The rotation of the fan blade 42 can blow air out from the exhaust port 41, thereby expelling the dust cleaned from the inside of the cleaning box 15, thus reducing the accumulation of dust in the cleaning box 15.

[0029] Furthermore, such as Figure 1-5 As shown, a bracket 5 is fixedly connected to the inner wall of the exhaust port 41, the end of the brush roller 16 passes through the bracket 5 and is rotatably connected to it, and a bearing is installed at the rotatable connection between the brush roller 16 and the bracket 5; a plurality of support rods 61 are fixedly connected to the top of the housing 11, and a baffle 62 is fixedly connected to the top of the support rods 61, and the baffle 62 is located at the top of the air inlet groove 21;

[0030] In use, the bracket 5 supports the end of the brush roller 16, the bearing reduces the vibration and friction of the brush roller 16 during rotation, and the support rod 61 and baffle 62 provide dust protection from the top, thereby reducing dust collection.

[0031] Furthermore, such as Figure 1-5 As shown, the end of the exhaust port 41 is fixedly connected to the pipe 7. During use, the pipe 7 needs to be adjusted according to the requirements. The end of the pipe 7 is far away from the distribution cabinet. The pipe 7 is used to connect with the exhaust port 41. The exhaust port 41 is used to guide the exhaust of dusty air away from the distribution box.

[0032] Working principle: During use, the connecting seat 12 is installed at the air inlet of the distribution cabinet. The air inlet of the distribution cabinet is connected to the air outlet 22 through the connecting seat 12. During cleaning, the first motor 17 is started periodically, and the roller 13 can rotate inside the housing 11. The through groove 24 on the roller 13 is aligned with the air outlet 22, and the air inlet 21 and the filter 23 are aligned. Then, during the air intake and heat dissipation process of the distribution box fan, the air is filtered through the filter plate 14 in its filter 23 and then passes through the cavity and the air outlet 22. 2. When cleaning is required, the first motor 17 drives the roller 13 to rotate, aligning the filter plate 14 with the cleaning groove. During the rotation of the roller 13, the filter plate 14 and the brush roller 16 come into contact and rub against each other, thus cleaning the filter plate 14 and achieving self-cleaning of the filter plate 14. This makes it convenient for workers to use, saving time and effort. The first motor 17 is a servo motor. It utilizes two cavities, a filter groove 23, a through groove 24, and the filter plate 14 to achieve this. One is used for air filtration, and the other is used for cleaning and dust removal from the filter plate 14, which is convenient to use. This switchable method can reduce the amount of dust generated during the cleaning of the filter plate 14 being sucked into the power distribution cabinet by the fan. In use, the brush roller 16 and the cleaning box 15 are rotatably connected, and the second motor 3 drives the brush roller 16 to rotate, thus improving the cleaning effect of the brush roller 16 on the filter plate 14. The end of the brush roller 16 is equipped with a fan blade 42. The rotation of the fan blade 42 can blow air out from the exhaust port 41, thereby expelling the dust cleaned from the inside of the cleaning box 15, thus reducing the accumulation of dust in the cleaning box 15. In use, the bracket 5 is provided to support the end of the brush roller 16. The bearing is provided to reduce the shaking and friction of the brush roller 16 during rotation. The support rod 61 and the baffle 62 are provided to block dust from the top, thereby reducing the dust collection effect.
