Abstract
Description
Technical Field
[0001] This utility model specifically relates to an electrical insulator cleaning component and a substation. Background Technology
[0002] With the rapid development of the national economy and the power industry, substations, as key nodes in power transmission and distribution, are of paramount importance for their safe and stable operation. Outdoor equipment in substations, such as insulators, bushings, and surge arresters, are exposed to complex atmospheric environments for extended periods, easily accumulating contaminants like salt, dust, bird droppings, and industrial pollutants on their surfaces. Under dry conditions, these contaminants have little impact on insulation performance. However, in humid weather conditions such as fog or dew, the electrolytes in the contaminants dissolve, forming a conductive film on the insulator surface. This significantly reduces insulation strength and drastically increases leakage current. In severe cases, it can trigger localized arcing or even surface flashover. Pollution flashover accidents can cause line tripping, equipment damage, and widespread power outages, posing a serious threat to the stability and reliability of the power grid and resulting in substantial economic losses.
[0003] Currently, the cleaning and maintenance of electrical insulators in substations mainly relies on manual cleaning. This method requires the equipment to be powered off, and maintenance personnel use cloths soaked in detergent or special tools to wipe the insulators from a height. Due to the special shape of electrical insulators, ordinary cloths or brushes cannot closely fit the complex contours of the insulator skirts, resulting in many blind spots in cleaning grooves and inner walls, and dirt cannot be thoroughly removed. During the cleaning process, maintenance personnel need to frequently change the wiping surface or wash the cloth, which is particularly inconvenient when working at height, greatly reducing work efficiency and prolonging the work time.
[0004] Therefore, it is necessary to invent an electrical insulator cleaning component and a substation to solve the above problems. Utility Model Content

Specifically, the telescopic rod 1 includes a main rod 11 and a telescopic auxiliary rod 12. The telescopic auxiliary rod 12 is installed inside the main rod 11. The end of the telescopic auxiliary rod 12 is provided with a telescopic groove 13. The top of the telescopic groove 13 is provided with a movable groove 14. The telescopic cleaning component 3 is installed in the telescopic groove 13 and the movable groove 14. Specifically, the telescopic cleaning component 3 includes two sets of symmetrically arranged telescopic moving strips 31. A movable fixing plate 32 matching the moving groove 14 is provided above the end of the telescopic moving strip 31. The other end of the telescopic moving strip 31 extends and is fixed to the end of the hanging rod 2. A cleaning cotton 33 is fixed on the inner side of the telescopic moving strip 31 at the position outside the telescopic auxiliary rod 12. The movable fixing plate 32 presses the front telescopic moving strip 31 to expand outward, and the cleaning cotton 33 on both sides wraps around the outside of the electrical insulator 4.
[0018] Specifically, the fixed end of the boom 2 is installed on the top mounting plane 15 of the telescopic auxiliary boom 12, and the moving groove 14 is provided on the mounting plane 15, and there are two sets of them. The telescopic groove 13 matches the two sets of moving grooves 14, and the telescopic groove 13 is arc-shaped. The telescopic moving bar 31 matches the telescopic groove 13 in an arc shape.
[0019] Specifically, a positioning stud 5 is provided on one side of the mounting end of the boom 2. The positioning stud 5 is matched with the movable fixing plate 32. The bottom sides of the movable fixing plate 32 are respectively connected to the telescopic moving strips 31 on both sides. The plate has an adjustment hole 34 that matches the positioning stud 5. The adjustment hole 34 is installed on the positioning stud 5. An adjustment nut 6 is also fixed on one side. The end of the positioning stud 5 is provided with a limit ring 51.
[0020] Specifically, the front end of the telescopic moving strip 31 is connected to the cleaning cotton 33 in a silicone material, and when the rear telescopic moving strip 31 moves forward, the front two telescopic moving strips 31 expand outward.
[0021] Specifically, the end of the main rod 11 is provided with a receiving groove 16 for accommodating the telescopic auxiliary rod 12, and the bottom outer wall of the main rod 11 is provided with a hand-held part 17.
[0022] A substation includes the aforementioned electrical insulator cleaning assembly.
[0023] In this embodiment, the telescopic rod 1 adopts a nested telescopic structure, including a main rod 11 and a telescopic auxiliary rod 12. The telescopic auxiliary rod 12 is fitted into the internal cavity of the main rod 11, allowing it to freely extend and retract along the axial direction of the main rod 11. A receiving groove 16 is machined at the end of the main rod 11 to accommodate the telescopic auxiliary rod 12, ensuring that the telescopic auxiliary rod 12 can be stored in the receiving groove 16 when fully retracted, reducing the overall space occupied by the component. At the same time, a handle 17 is integrally formed or fixed to the bottom outer wall of the main rod 11, and the surface of the handle 17 can be provided with anti-slip texture to improve the stability of the operator's grip.
[0024] In this embodiment, a flat mounting surface 15 is formed at the top end of the telescopic auxiliary rod 12. The fixed end of the hanger rod 2 is fixed to the mounting surface 15 by welding or high-strength bolts, so that the extension end of the hanger rod 2 faces the front of the telescopic rod 1, and the axis of the hanger rod 2 forms a certain angle with the axis of the telescopic rod 1, ensuring that the end of the hanger rod 2 can accurately extend to the area to be cleaned above the electrical insulator 4.
[0025] In this embodiment, the installation of the telescopic cleaning component begins with the following steps: First, a telescopic groove 13 is machined at the end of the telescopic auxiliary rod 12. The telescopic groove 13 is an arc-shaped structure adapted to the outer contour of the electrical insulator 4 and extends along the length of the telescopic auxiliary rod 12. Two sets of symmetrical movable grooves 14 are formed on the mounting plane 15 corresponding to the top position of the telescopic groove 13. The movable grooves 14 and the telescopic groove 13 are connected to form a T-shaped installation channel. Two sets of symmetrically arranged telescopic movable strips 31 are fitted and installed within the telescopic grooves 13. Since the telescopic groove 13 is arc-shaped, the telescopic movable strips 31 also adopt a matching arc-shaped structure to ensure smooth sliding along the telescopic groove 13. An integrally formed movable fixing plate 32 is formed above the end of the telescopic movable strip 31. The size of the movable fixing plate 32 matches the movable groove 14. The movable fixing plate 32 is embedded into the movable groove 14 to achieve sliding and limiting cooperation between the telescopic movable strip 31 and the telescopic auxiliary rod 12. Then, the other end of the telescopic moving strip 31 is welded and fixed to the extension end of the rod 2, so that the rod 2 forms a hoisting support for the telescopic moving strip 31; finally, the cleaning cotton 33 is fixed by adhesive or snap-fit connection on the inner side of the telescopic moving strip 31 and outside the telescopic auxiliary rod 12. The cleaning cotton 33 is made of highly absorbent, low-wear microfiber material, and its surface can be pre-impregnated with neutral cleaning liquid.
[0026] In this embodiment, a positioning stud 5 is welded to one side of the mounting end of the boom 2, and the axis of the positioning stud 5 is parallel to the length direction of the moving groove 14. An adjustment hole 34 is machined in the middle of the moving fixing plate 32, and the inner diameter of the adjustment hole 34 is adapted to the outer diameter of the positioning stud 5. The moving fixing plate 32 is then fitted onto the positioning stud 5 through the adjustment hole 34. An adjusting nut 6 is screwed into the end of the positioning stud 5 away from the boom 2, and a limiting ring 51 is integrally formed at the end of the positioning stud 5. The outer diameter of the limiting ring 51 is larger than the inner diameter of the adjustment hole 34 to prevent the adjusting nut 6 from falling off the positioning stud 5, and at the same time to limit the maximum movement stroke of the moving fixing plate 32.
[0027] In this embodiment, the nested telescopic design of the main rod 11 and the telescopic auxiliary rod 12 of the telescopic rod 1 allows for flexible adjustment of the overall length according to the installation height of the electrical insulator 4, adapting to the cleaning needs of insulators at different heights. This is particularly suitable for ground-based operations on high-altitude insulators, eliminating the need for operators to climb and reducing operational risks and labor intensity. The anti-slip design of the handheld part 17 further enhances stability during operation, preventing components from slipping. Simultaneously, through the cooperation of the positioning stud 5, adjusting nut 6, and movable fixing plate 32, the expansion and contraction of the cleaning cotton 33 can be achieved simply by turning the adjusting nut, making operation simple and efficient; a single person can complete the entire cleaning process.
[0028] In this embodiment, the connection between the front end of the telescopic moving strip 31 and the cleaning cotton 33 is made of silicone. Silicone has good elasticity and flexibility, which can buffer the contact pressure between the cleaning cotton 33 and the surface of the electrical insulator 4 during the cleaning process, avoiding damage to the glaze layer on the surface of the insulator caused by rigid contact. At the same time, the cleaning cotton 33 itself is soft and has a moderate coefficient of friction, which can ensure the cleaning effect without damaging the insulation performance of the insulator. In addition, the wrapping force of the cleaning cotton 33 can be flexibly adjusted according to the material characteristics of the insulator by adjusting the nut 6, further avoiding the problem of insulator damage caused by excessive compression.
[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
