[0025] The rear side of the support base 1 has several through holes 10. The rear side of the support base 1 is fixedly connected to a receiving box 11 with an open front side. The inner cavity of the receiving box 11 is fixedly connected to an anti-static rod 12. The rear side of the receiving box 11 is fixedly connected to a filter box 14 with an open front side. The rear side of the receiving box 11 has a connecting opening 13. The rear side of the filter box 14 is provided with a filter screen plate 18. The inner cavity of the filter box 14 is provided with a brush mechanism for cleaning the filter screen plate 18.

[0026] In this embodiment, after the static elimination rod 12 is activated, negative ions are injected into the inner cavity of the support base 1, thereby eliminating static electricity on the surfaces of the support base 1, the busbar body 2, and the insulating pad 3, improving the stability and safety of the high-voltage distribution cabinet busbar during operation. Furthermore, the filter screen 18 prevents impurities and dust from entering the inner cavity of the receiving box 11, thus improving the protection of the support base 1, the busbar body 2, and the insulating pad 3.

[0027] Furthermore, the brush mechanism includes a motor 21, a threaded rod 15, and a threaded sleeve 16. The motor 21 is fixedly connected to one end face of the filter box 14. The threaded rod 15 is rotatably disposed in the inner cavity of the filter box 14, and one end is fixedly connected to the output shaft of the motor 21. The threaded sleeve 16 is threadedly connected to the surface of the threaded rod 15, and a brush plate 17 that contacts the surface of the filter screen plate 18 is fixedly connected to the rear side of the threaded sleeve 16.

[0028] In this embodiment, after the motor 21 is working, it can drive the threaded rod 15 to rotate. After the threaded sleeve 16 drives the brush plate 17 to move, the surface of the filter screen plate 18 can be brushed and cleaned. This can prevent impurities from clogging the surface of the filter screen plate 18, improve the filtration efficiency of the filter screen plate 18 for airflow, and facilitate the use of static electricity elimination.

[0029] Furthermore, a guide rod 19 is fixedly connected laterally to the inner cavity of the filter box 14, and a limiting sleeve 20 is fixedly connected to the side wall of the threaded sleeve 16. The limiting sleeve 20 is slidably sleeved on the surface of the guide rod 19.

[0032] In this embodiment, after the movable U-shaped plate 6 slides against the surface of the mounting rib 4, the height of the support base 1 can be adjusted to accommodate different connection height requirements and facilitate assembly work inside the power distribution cabinet. After the height of the movable U-shaped plate 6 is adjusted, the torsion handle 8 can be turned. After the inner end of the bolt 7 abuts against the surface of the mounting rib 4, the movable U-shaped plate 6 can be moved to a new position and locked in place, thereby fixing the height of the support base 1.

[0034] Furthermore, several heat dissipation fins 9 are fixedly connected to the top and bottom of the support base 1. The multiple heat dissipation fins 9 are evenly distributed and spaced along the horizontal direction from the front to the rear of the support base 1. The multiple heat dissipation fins 9 facilitate heat dissipation from the surface of the support base 1 and extend the service life of the device.

[0035] The working principle and usage process of this utility model are as follows: After the utility model is installed, the movable U-shaped plate 6 slides against the surface of the mounting rib 4, thereby adjusting the height of the support base 1 to accommodate different connection height requirements and facilitate assembly work inside the distribution cabinet. After adjusting the height of the movable U-shaped plate 6, the torsion handle 8 can be turned. The inner end of the bolt 7 abuts against the surface of the mounting rib 4, locking the movable U-shaped plate 6 in place and thus fixing the height of the support base 1. After installation, the static eliminator 12 is used to inject static electricity into the inner cavity of the support base 1. The introduction of negative ions eliminates static electricity on the surfaces of the support base 1, busbar body 2, and insulating pad 3, improving the stability and safety of the high-voltage distribution cabinet busbar during operation. The filter screen 18 prevents impurities and dust from entering the cavity of the receiving box 11, enhancing protection for the support base 1, busbar body 2, and insulating pad 3. Furthermore, the motor 21, when in operation, drives the threaded rod 15 to rotate, which in turn moves the brush plate 17 via the threaded sleeve 16, cleaning the surface of the filter screen 18 and preventing impurities from clogging it.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
