[0026] Example

[0027] like Figure 1 and Figure 2As shown, the present invention proposes a self-cleaning environmentally friendly ring main unit, comprising: a ring main unit 1, a door 2 hinged to the front of the ring main unit 1 and equipped with a door lock to protect the equipment inside the ring main unit 1; a cooling fan 3 for heat dissipation through one side of the ring main unit 1, and a mounting frame 4 through the other side of the ring main unit 1, wherein the cooling fan 3 and the mounting frame 4 are symmetrically arranged, and multiple filters 5 for filtering dust are fixedly arranged between the mounting frames 4; and a cleaning component 6 fixedly arranged above the cooling fan 3 for automatically cleaning the filters 5, thereby improving the efficiency of cleaning the filters 5.

[0028] like Figures 2 to 5 As shown, the cleaning component 6 includes a support frame 601, a guide groove 602 on the support frame 601, a guide block 603 slidably disposed inside the guide groove 602, and a connecting plate 604 fixedly disposed between the guide blocks 603, which can guide the connecting plate 604 and make the vertical sliding of the connecting plate 604 more stable. An electric push rod 605 is fixedly installed on the upper end of the support frame 601. The output end of the electric push rod 605 is fixedly connected to the connecting plate 604, which can drive the connecting plate 604 to move vertically. The bottom surface of the connecting plate 604 is fixed. Multiple sets of support rods 606 are fixedly arranged, and the support rods 606 and the filter screen 5 are staggered. A mounting plate 607 is fixedly arranged between the support rods 606. A connecting rod 608 is arranged through the mounting plate 607, and the connecting rod 608 rotates on the mounting plate 607 by rotation. A circular brush disc 609 is fixedly connected to one end of the connecting rod 608, and a gear 610 is connected to the other end of the connecting rod 608. The gears 610 are meshed with each other, which can make multiple circular brush discs 609 rotate simultaneously, thereby improving the efficiency of cleaning the filter screen 5.

[0029] Furthermore, the cleaning assembly 6 also includes a rack 611 fixedly mounted on the cooling fan 3. The rack 611 is meshed with the gear 610 and can rotate during the vertical movement of the gear 610, thereby making the circular brush 609 clean more thoroughly.

[0030] like Figure 2 and Figure 3 As shown, a set of fixing blocks 7 are fixedly installed below the cooling fan 3, and the fixing blocks 7 are symmetrically arranged. The opposite surfaces of the fixing blocks 7 are respectively provided with sliding grooves 8, and the sliding grooves 8 are "T" shaped. A slider 9 is slidably arranged inside the sliding grooves 8, and the slider 9 is also "T" shaped, which makes the horizontal sliding of the slider 9 more stable. A collection box 10 is fixedly installed between the sliders 9. The collection box 10 is located directly below the filter screen 5, which facilitates the collection of cleaned dust for easy disposal.

[0031] Furthermore, the filter holes on the multiple filter screens 5 decrease in size from the outside to the inside, which can filter impurities in the air in multiple layers, reducing the contamination of the internal equipment of the ring main unit 1, thereby improving the reliability and stability of the equipment.

[0032] In addition, the filter screen 5 and the circular brush plate 609 are arranged alternately, which can clean multiple filter screens 5 at the same time, improving the cleaning efficiency.

[0033] The working principle of this embodiment is as follows: When cleaning the filter screen 5, the electric push rod 605 is activated, which pushes the connecting plate 604 to move vertically downward. The connecting plate 604 drives the guide block 603 to slide vertically inside the guide groove 602, guiding the connecting plate 604 and making the vertical sliding of the connecting plate 604 more stable. At the same time, the connecting plate 604 drives the mounting plate 607 to move vertically downward through the support rod 606. The mounting plate 607 drives the circular brush disc 609 and the gear 610 to move vertically downward through the linkage rod 608.

[0034] Furthermore, during its vertical downward movement, gear 610 engages with rack 611, causing gear 610 to drive circular brush disc 609 to rotate via connecting rod 608. As the circular brush disc 609 rotates, it moves vertically downward, cleaning the filter screen 5. Simultaneously, the meshing of gears 610 drives multiple circular brush discs 609 to rotate, effectively removing impurities and dirt from the surface of the filter screen 5, reducing the labor intensity of manual cleaning and improving cleaning efficiency.

[0035] Furthermore, the cleaned dust falls into the collection box 10 through the gaps between the filter screens 5. With the cooperation of the sliding groove 8 and the slider 9, the collection box 10 can be easily pulled out horizontally, making it convenient to clean the impurities collected in the collection box 10 in a concentrated manner, preventing the impurities from re-entering the air, thereby improving the cleaning effect.

[0036] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
