[0029] Example 2 See Figures 1 to 8 Furthermore, based on Embodiment 1, the cleaning mechanism 3 further includes a motor 31, which is fixedly connected to the top of the insulator body 1. An output shaft 32 is fixedly connected to the output end of the motor 31. A drive assembly 33 is provided on the outer wall of the output shaft 32. A connecting shaft 34 is provided inside the drive assembly 33. A small gear 35 is fixedly connected to the outer wall of the connecting shaft 34. A horizontal plate 36 is provided inside the protective mechanism 4. A large gear 38 meshes with the outer ring of the small gear 35. A connecting rod 39 is fixedly connected to the bottom of the large gear 38. A circle 301 is fixedly connected to the bottom of the connecting rod 39. A support column 302 is fixedly connected to the bottom of the circle 301. A vertical plate 37 is fixedly connected to the top of the insulator body 1. A cleaning frame 303 is fixedly connected to the bottom of the support column 302, which facilitates the cleaning of dust and impurities on the outside of the insulator body 1.

[0030] Furthermore, the large gear 38 is rotatably connected to the outer wall of the insulator body 1, the output shaft 32 passes through the vertical plate 37 and rotates, and the threaded rod 24 is rotatably connected to the inside of the horizontal plate 36, thereby achieving the purpose of stable support.

[0031] Furthermore, the drive assembly 33 includes a driving bevel gear and a driven bevel gear. The output shaft 32 is fixedly connected to the inner ring of the driving bevel gear, and the drive assembly 33 is fixedly connected to the inner ring of the driven bevel gear. The driving bevel gear and the driven bevel gear mesh, thereby achieving the purpose of stable driving.

[0032] Example 3 See Figures 1 to 8 Furthermore, based on Embodiment 1 and Embodiment 2, the protective mechanism 4 further includes a support plate 41, which is fixedly connected to the outer wall of the insulator body 1. A protective frame 42 is fixedly connected to the outer side of the support plate 41 away from the insulator body 1. An insertion frame 43 is fixedly connected to the outer side of the protective frame 42. An insertion block 45 is movably connected inside the insertion frame 43. A top cover 44 is provided on the top of the support plate 41. Bolts 46 are threaded inside the insertion block 45 to facilitate the installation of the top cover 44.

[0033] Furthermore, the inner wall of the support plate 41 is fixedly connected to the outer side of the horizontal plate 36, the bottom of the protective frame 42 has an annular opening, the connecting rod 39 passes through the annular opening, one end of the bolt 46 is fixedly connected to a twist sleeve, and the bolt 46 passes through the insertion frame 43 and moves.

[0034] In actual operation, when this device is used, the square block 22 is inserted into the inside of the square box 21 to achieve initial support and limitation. At the same time, the rotating sleeve can drive the threaded rod 24 to rotate. Since the threaded rod 24 and the fixed frame 23 are threadedly connected, and the rectangular plate 25 can slide and be limited on the inner wall of the fixed frame 23, the threaded rod 24 will drive the rectangular plate 25 to move, so that the rectangular plate 25 can drive the insert post 26 to be inserted into the slot opened in the square block 22, thereby achieving the purpose of limitation and preventing the square block 22 from being pulled out from the inside of the square box 21. This allows the cylinder 202 to be installed. Similarly, the cylinder 202 can also be disassembled. During long-term use, it is convenient to disassemble, repair and maintain the cylinder 202, achieving good operating efficiency and further improving the convenience of operation and use.

[0035] When the insulator body 1 is affected by external factors and bends, the connecting post 28 can push the circular plate 29 to slide and limit its movement on the inner wall of the cylinder 202. At the same time, the circular plate 29 can compress the spring 201, and the connecting post 28 can drive the insertion shaft to move on the inner wall of the connecting plate 27. This converts the external impact force into the sliding force of the circular plate 29, and the circular plate 29 can compress the spring 201, converting it back into elastic potential energy. This elastic potential energy can then be converted into the frictional heat energy of the circular plate 29, achieving the purpose of shock resistance. This also helps to prevent bending of the insulator body 1, further reducing the impact of external factors on the insulator body 1, and extending the service life of the insulator body 1, thus enhancing the practicality of the device.

[0036] During prolonged use, when a significant amount of dust and impurities accumulate on the outer side of the insulator body 1, the motor 31 can be activated. The output end of the motor 31 can drive the output shaft 32 to rotate. The output shaft 32 can be driven by the drive assembly 33 to rotate the connecting shaft 34. The connecting shaft 34 can drive the pinion 35 to rotate, which in turn drives the large gear 38 to rotate. The large gear 38 can then drive the connecting rod 39 to rotate around the midpoint of the large gear 38. The connecting rod 39 can then drive the support column 302 to rotate via the circle 301. The support column 302 can then drive the cleaning frame 303 to rotate. The cleaning frame 303 can clean the dust and impurities accumulated on the outer side of the insulator body 1, reducing the impact of dust and impurities on the normal operation of the insulator body 1. This allows the insulator body 1 to work better, eliminating the need for manual cleaning and improving the convenience and flexibility of the device.

[0037] During prolonged use, when it is necessary to inspect and maintain the components inside the protective frame 42, the bolt 46 can be rotated by rotating the second twist sleeve to unscrew it from the inside of the insert 45, thus removing the limit on the insert 45. At this time, the insert 45 can be pulled out from the inside of the insert frame 43 through the top cover 44. The top cover 44 can be pulled out from the top of the protective frame 42, thus enabling the disassembly of the top cover 44. This facilitates the inspection and maintenance of the components inside the protective frame 42 by the staff, and achieves good disassembly and assembly efficiency, further improving the convenience of operation and reducing the time spent in the inspection and maintenance process.
