[0021] The utility model provides Figure 1 to Figure 4The power porcelain insulator with self-cleaning function shown in the figure comprises a porcelain rod 1, the upper and lower ends of the porcelain rod 1 are both glued with metal parts, the porcelain rod 1 is fixedly connected with an umbrella skirt 2, and the umbrella skirt 2 is provided in multiple numbers, and the multiple umbrella skirts 2 are distributed at equal distances.

[0022] Considering that the existing power porcelain insulators often fail due to bird damage during use, and the excrement drips onto the shed 2, affecting the use effect of the power porcelain insulator, and birds tend to stay on the shed 2 at the top position, a transverse ring 14 is fixedly connected to the top of the porcelain rod 1, and the shed 2 at the top position is located below the transverse ring 14. A vertical ring 3 is fixedly connected to the outer ring of the transverse ring 14, and a sliding component is slidably arranged on the transverse ring 14. The sliding component is arranged in multiple groups, and the multiple groups of sliding components are evenly distributed. The sliding component includes a U-shaped ring sleeve 4, an upper ring 5 and a lower ring 7, and the U-shaped ring sleeve 4 surrounds the outer side of the vertical ring 3. And the upper and lower ends of the vertical ring 3 are both provided with an active gap with the inner wall of the U-shaped ring sleeve 4, so that the U-shaped ring sleeve 4 can swing up and down. The upper ring 5 is fixedly connected to the lower surface of the top of the U-shaped ring sleeve 4 and is located above the transverse ring 14, and the lower ring 7 is fixedly connected to the upper surface of the bottom of the U-shaped ring sleeve 4 and is located below the transverse ring 14. A support plate 9 is fixedly connected to the outer wall of the U-shaped ring sleeve 4, and a sequin 10 is fixedly inlaid on the support plate 9. The sequin 10 can reflect sunlight to achieve the effect of driving away birds.
[0023] Since there are movable gaps between the upper and lower ends of the vertical ring 3 and the inner wall of the U-shaped ring sleeve 4, and under the limiting action of the upper ring 5 and the lower ring 7, under the action of external wind force, the support plate 9 and the U-shaped ring sleeve 4 will swing, and a sound will be generated when the U-shaped ring sleeve 4 contacts the vertical ring 3. At the same time, the support plate 9 drives the sequins 10 to swing, so that the sunlight reflected by the sequins 10 is directed in different directions, thereby achieving the effect of driving away birds and avoiding the dirt of the power porcelain insulator caused by the birds staying.
[0024] A structure such as a transverse ring 14 is arranged above the umbrella skirt 2 at the top position to prevent birds from landing directly on the umbrella skirt 2.
[0025] In addition, when the bird stays on the support plate 9 and the U-shaped ring 4, the support plate 9 and the U-shaped ring 4 will swing, so that the bird will not stay.
[0026] By arranging structures such as the horizontal ring 14, the vertical ring 3, the support plate 9 and the U-shaped ring sleeve 4, the bird-repelling effect is achieved, and the contamination of the power porcelain insulator caused by the birds staying there is avoided.
[0027] In order to improve the sliding smoothness of the sliding component, an upper ball 6 is movably embedded in the bottom of the upper ring 5, and a lower ball 8 is movably embedded in the top of the lower ring 7.
[0028] In order to make multiple groups of sliding parts slide synchronously, a steel wire segment 11 is fixedly connected between two adjacent U-shaped ring sleeves 4, and the steel wire segment 11 does not affect the swing of the support plate 9 and the U-shaped ring sleeve 4 in one group of sliding parts. When one group of sliding parts moves, it drives the other multiple groups of sliding parts to move at the same time, thereby improving the bird-repelling effect.
