DETAILED DESCRIPTION

[0019] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] A low voltage distribution box, such as Figure 1 and Figure 3 As shown, it includes a distribution box 1, a vent 2 is opened on the side wall of the distribution box 1, and a plurality of inclined dust-proof leaves 3 are welded on the side wall of the vent 2. The dust-proof leaves 3 can reduce the entry of rainwater or dust into the distribution box 1 from the vent 2, affecting the normal operation of the distribution equipment in the distribution box 1. Dust-removing brushes 4 are arranged on the surfaces of adjacent dust-proof leaves 3. The dust-removing brushes 4 are driven to slide along the inclined surfaces of the dust-proof leaves 3, so that the dust on the dust-proof leaves 3 is cleaned off. Two driving brushes for driving the dust-removing brushes 4 to slide are slidably connected in the distribution box 1. Parts, one end of the adjacent driving part close to the dust-proof leaf 3 is rotatably connected to the dust removal brush 4, and the other end of the driving part close to the dust removal brush 4 is rotatably connected to the distribution box 1. When people apply a pulling force away from the bottom surface of the distribution box 1 to the driving part, the end of the driving part away from the dust removal brush 4 slides along the height direction of the distribution box 1, and the end of the driving part close to the dust removal brush 4 applies a thrust away from the inner wall of the distribution box 1 to the dust removal brush 4, so that the dust removal brush 4 slides along the inclined surface of the dust-proof leaf 3, and the dust attached to the dust-proof leaf 3 is cleaned off by the dust removal brush 4.

[0021] like Figure 1 , Figure 3 and Figure 4 As shown, adjacent driving members are symmetrically arranged along the axis of symmetry in the height direction of the vent 2, and the ends of the adjacent driving members close to each other are rotatably connected to the side wall of the dust removal brush 4, so that the dust removal brush 4 can slide more smoothly along the surface of the dust prevention leaf 3. The driving member includes a sliding rod 5 slidably connected to the distribution box 1 and a plurality of rotating plates 6 connected to the side wall of the sliding rod 5 through an upper pull rope 8. The adjacent rotating plates 6 are rotatably connected to the distribution box 1, and the dust removal brush 4 is rotatably connected to the end of the rotating plate 6 away from the sliding rod 5. When people apply a pulling force to the sliding rod 5 away from the bottom surface of the distribution box 1, the adjacent sliding rod 5 applies a pulling force to the end of the rotating plate 6 away from the dust prevention leaf 3 away from the bottom surface of the distribution box 1 through the upper pull rope 8, so that the end of the rotating plate 6 close to the dust prevention leaf 3 applies a thrust to the dust removal brush 4 away from the inner wall of the distribution box 1, and the dust removal brush 4 slides along the surface of the dust prevention leaf 3.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, a plurality of rotating grooves 7 for accommodating the rotation of the rotating plate 6 are provided on the side walls of the vent 2. The bottom walls of the rotating grooves 7 are arranged to be inclined toward the bottom surface of the distribution box body 1. The bottom walls of the rotating grooves 7 are arranged to be in the same horizontal plane as the surface of the dust-proof leaf 3, so that when the slide bar 5 applies a pulling force to the rotating plate 6, the rotating plate 6 rotates along the inclined surface of the rotating grooves 7, thereby driving the dust removal brush 4 to slide along the inclined surface of the dust-proof leaf 3. The dust removal brush 4 is arranged to be retractable to prevent the rotating plate 6 from rotating to pass through the rotating groove 7 at one end close to the dust removal brush 4 due to the increase in the distance between the rotating plates 6 on adjacent slide bars 5. The dust removal brush 4 cannot slide normally along the surface of the dust-proof leaf 3 due to its own length limitation. The end of the dust removal brush 4 close to the rotating plate 6 is inserted into the rotating groove 7 and is slidably connected to the bottom wall of the rotating groove 7, so that the dust removal brush 4 slides more stably along the surface of the dust-proof leaf 3.

[0023] like Figure 1 , Figure 3 and Figure 4 As shown, the rotating plate 6 is connected to the bottom wall of the rotating groove 7 through a torsion piece 9. The torsion piece 9 is a torsion spring with elastic deformation performance. In the initial state, the distance between the end of the rotating plate 6 close to the dust removal brush 4 and the inner wall of the distribution box 1 is smaller than the distance between the end of the rotating plate 6 away from the dust removal brush 4 and the inner wall of the distribution box 1, so that the dust removal brush 4 is located at the end close to the top surface of the dustproof leaf 3. When the upper pull rope 8 applies a pulling force close to the top surface of the distribution box 1 to the end of the rotating plate 6 away from the dust removal brush 4, the torsion piece 9 is deformed under the action of the rotating plate 6, and the end of the rotating plate 6 close to the dust removal brush 4 applies a thrust to the dust removal brush 4 along the bottom wall of the rotating groove 7 away from the inner wall of the distribution box 1, so that the dust removal brush 4 slides along the surface of the dustproof leaf 3. When the pulling force applied to the slide rod 5 disappears, the torsion piece 9 drives the rotating plate 6 to restore its initial state under its own elastic deformation performance.

[0024] like Figure 1-Figure 5As shown, a sliding groove 10 for accommodating the sliding of the sliding rod 5 is provided in the distribution box 1, and the sliding groove 10 is connected to the adjacent rotating groove 7 located on the same side. The sliding groove 10 is arranged at an end of the rotating groove 7 away from the dustproof leaf 3 and close to the inner wall of the distribution box 1, so that when the sliding rod 5 slides in the sliding groove 10, a pulling force is applied to the end of the rotating plate 6 away from the dust removal brush 4 in the direction close to the inner wall of the distribution box 1. An upper pull groove 11 connected to the adjacent sliding groove 10 is provided on the side wall of the distribution box 1, and an upper pull rod 12 is slidably connected in the upper pull groove 11. The upper pull rod 12 It is welded between adjacent sliding bars 5 so that people can drive adjacent sliding bars 5 to slide together by applying pulling force to the upper pull rod 12, so that several dust removal brushes 4 can slide more smoothly on the surface of the dust-proof leaf 3 together. An opening connected to the outside is provided on one side of the upper pull groove 11, and a handle bar 13 is rotatably connected to the opening of the upper pull groove 11. The upper pull rod 12 is bonded to the handle bar 13 through an upper pull rope 14, so that people can drive the sliding bar 5 to slide in the upper pull groove 11 by rotating the upper pull rod 12, thereby driving the dust removal brush 4 to slide on the surface of the dust-proof leaf 3.

[0025] Working principle: In the initial state, the distance between the end of the rotating plate 6 close to the dust removal brush 4 and the inner wall of the distribution box 1 is smaller than the distance between the end of the rotating plate 6 away from the dust removal brush 4 and the inner wall of the distribution box 1. The dust removal brush 4 is located at the end close to the top surface of the dust-proof leaf 3. When people need to clean the dust-proof leaf 3, firstly, a pulling force is applied to the handle 13 away from the dust removal brush 4, so that the handle 13 rotates in the direction of the pulling force, and the upper pull rod 12 moves along the upper pull groove 11 to the distribution box under the action of the upper pull rope 14. The rotating plate 6 slides in the direction of the top surface of the body 1, and the adjacent sliding rod 5 applies a pulling force to the end of the rotating plate 6 away from the dust removal brush 4 under the action of the upper pull rope 8. The rotating plate 6 rotates along the inclined surface of the bottom wall of the rotating groove 7, and the end of the rotating plate 6 close to the dust removal brush 4 drives the dust removal brush 4 to slide along the inclined surface of the dust prevention leaf 3, so that the dust above the dust prevention leaf 3 is cleaned up. When people cancel the pulling force applied to the handle 13, the rotating plate 6 drives the rotating plate 6 and the dust removal brush 4 to restore the initial state under the elastic deformation performance of the torsion member 9.
