At this time, the vibration generated by the impact of the second magnetic block 34 on the filter screen plate 25 can further increase the anti-blocking effect of the filter screen plate 25 when in use.
[0029] like Figure 3 , 7 As shown, the side wall of the screw 17 is fixedly connected to the telescopic rod 4; the end of the telescopic rod 4 is fixedly connected to a clamping block 41; the side wall of the fixing plate 16 is provided with a clamping groove 42; when in use, after the screw 17 is rotated, the clamping block 41 is first held and pulled, and when it is pulled apart, the telescopic rod 4 is then held and pulled, and after the clamping block 41 is pulled to an appropriate length, the clamping block 41 will correspond to the position of the clamping groove 42, and at this time, the clamping block 41 is released, and under the action of the internal torsion spring at the hinge of the clamping block 41, the clamping block 41 will automatically recover and be clamped into the side wall of the clamping groove 42, so that the screw 17 can be fixed. In this process, it can reduce the difficulty in fixing the screw 17 after the rotation is completed, resulting in the screw 17 rotating when it is accidentally touched, thereby causing a certain impact on the maintenance of the distribution cabinet body 1. At this time, the clamping block 41 is set to prevent the screw 17 from rotating.
[0030] like Figure 5As shown, a pair of pulleys 5 are hinged on the side wall of the scraper 24; the pulleys 5 are symmetrically arranged on both sides of the scraper 24 and have the same structure; a rubber block 51 is fixedly connected to the side wall of the pulley 5; when in use, when the scraper 24 is rotating, the pulley 5 will roll on the side wall of the filter screen plate 25, and as the pulley 5 rolls, the rubber block 51 will rotate to contact the filter screen plate 25, at this time, the pulley 5 can be lifted up under the elastic action of the rubber block 51, and then it will automatically recover under the action of the internal torsion spring at the hinge of the pulley 5, and hit the side wall of the filter screen plate 25, and the vibration generated by the impact can vibrate off the dust and impurities attached to the side wall of the filter screen plate 25, in this process, the poor cleaning effect of the filter screen plate 25 can be reduced, resulting in dust and impurities accumulating on the side wall of the filter screen plate 25, thereby affecting the flow effect of the airflow, at this time, through the mutual cooperation of the pulley 5 and the rubber block 51, the cleaning effect of the filter screen plate 25 is further increased, and the anti-clogging effect of the filter screen plate 25 when in use is increased.
[0031] like Figure 3 , 7 As shown, the side wall of the card block 41 is fixedly connected with a buckle plate 6; the side wall of the buckle plate 6 is evenly fixedly connected with a plurality of rubber strips 61; when in use, by placing a finger on the side wall of the buckle plate 6 and pressing, the finger can be hooked under the arc action of the buckle plate 6, thereby reducing the finger from slipping off the side wall of the buckle plate 6, and at the same time, the surface of the finger will also be in full contact with the rubber strip 61, thereby generating a certain friction force, and then the card block 41 can be pressed open by pressing the buckle plate 6. In this process, it can reduce the difficulty of the staff in holding the card block 41 when it needs to pull the card block 41 open, causing it to slip off the side wall of the card block 41 when pulling. At this time, the buckle plate 6 and the rubber strip 61 are set, thereby facilitating the pulling of the card block 41 and increasing the firmness of the finger on the side wall of the card block 41.
[0032] like Figure 2 As shown, the side wall of the cleaning brush 19 is fixedly connected with a connecting rod 7; the connecting rod 7 passes through the wall of the cleaning brush 19 and is fixedly connected thereto; when in use, multiple cleaning brushes 19 can be fixedly connected by the connecting rod 7 so that they are concentrated together during cleaning. In this process, the cleaning brush 19 can be reduced to be relatively scattered during cleaning, resulting in poor cleaning effect of the cleaning brush 19. At this time, the connecting rod 7 is set to increase the concentration of the cleaning brush 19 during cleaning, thereby improving the cleaning effect of the distribution cabinet body 1.
[0033] During operation, the screw rod 17 is held and rotated, and the connecting block 15 can be moved as the screw rod 17 is rotated. At the same time, under the sliding cooperation between the guide rail 12 and the first slider 13, the first slider 13 will slide on the inner wall of the guide rail 12, and the connecting block 15 will slide on the side wall of the through hole 14. At this time, the mounting plate 11 will gradually move out of the distribution cabinet body 1, so that the circuit installed on the side wall of the mounting plate 11 can be repaired, and in the process of the movement of the mounting plate 11, the inner wall of the distribution cabinet body 1 can be cleaned by the full contact between the cleaning brush 19 and the inner wall of the distribution cabinet body 1, and the dust and impurities remaining on the inner wall of the distribution cabinet body 1 can be cleaned and swept out of the distribution cabinet body 1. After that, when the maintenance is completed, the screw rod 17 is The mounting plate 11 can be moved into the power distribution cabinet body 1 by rotating in the reverse direction. When the power distribution cabinet body 1 is in use, the drive motor 21 is started at the same time. The fan blades 22 can be driven to rotate by the drive motor 21. During the rotation of the fan blades 22, a certain amount of airflow will be generated, so that air can be blown into the power distribution cabinet body 1 to cool down and dissipate the heat generated when the power distribution cabinet body 1 is in use. When the airflow enters the power distribution cabinet body 1 through the protective shell 2, the filter screen 25 can filter the dust and impurities carried in the airflow, and the airflow will contact the spiral impeller 23 and generate a certain impact force to drive the spiral impeller 23 to rotate. As the spiral impeller 23 rotates, the scraper 24 can be driven to rotate. At this time, the scraper 24 and the filter screen 25 When the scraper 24 drives the first magnetic block 3 to rotate to the position corresponding to the second magnetic block 34, the second magnetic block 34 and the first magnetic block 3 will have an attraction, thereby pulling the second magnetic block 34 to one side of the first magnetic block 3.

After the block 41 is pulled to a suitable length, the block 41 will correspond to the position of the slot 42. At this time, the block 41 is released. Under the action of the internal torsion spring at the hinge of the block 41, the block 41 will automatically recover and be stuck in the side wall of the slot 42, so that the screw 17 can be fixed. When in use, when the scraper 24 is rotating, the pulley 5 will roll on the side wall of the filter screen plate 25. As the pulley 5 rolls, the rubber block 51 will rotate to contact the filter screen plate 25.At this time, the pulley 5 can be lifted up under the elastic action of the rubber block 51, and then it will automatically recover under the action of the internal torsion spring at the hinge of the pulley 5, and hit the side wall of the filter screen plate 25. The vibration generated by the impact can shake off the dust and impurities attached to the side wall of the filter screen plate 25. When in use, by placing a finger on the side wall of the gusset plate 6 and pressing it, the finger can be hooked under the arc action of the gusset plate 6 to reduce the finger from sliding off the side wall of the gusset plate 6. At the same time, the surface of the finger will fully contact the rubber strip 61, thereby generating a certain friction force. Then, the block 41 can be pressed open by pressing the gusset plate 6.
