Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figures 1 to 3 As shown, a maintenance device for the surface of power equipment includes a base plate 100, an intermediate shaft 200 and a rotating gear 300 disposed on the base plate 100. The intermediate shaft 200 is used to install insulators, and the rotating gear 300 is disposed on the maintenance device body, which is used to drive the maintenance device body to rotate.

[0028] like Figure 1 As shown, the maintenance device body includes a connecting post 400, a mounting post 500, and a cleaning component. The connecting post 400 is fixedly mounted on the rotating gear 300, and the mounting post 500 is fixedly connected to the connecting post 400. A cleaning component is provided on the side of the mounting post 500, and the cleaning component is used for cleaning the surface of the insulator.

[0029] like Figure 2 The cleaning assembly shown includes a connecting rod, a rotating column 600, and a brush head 700. One end of the connecting rod is fixedly connected to the mounting column 500, and the other end of the connecting rod is rotatably connected to the rotating column 600 via a first torsion spring. The rotating column 600 and the brush head 700 are rotatably connected via a second torsion spring. The surface of the brush head 700 is provided with a brush, which cleans the surface of the insulator.

[0030] In this invention, the maintenance device body rotates automatically via a drive motor 800 and a gear transmission system, eliminating the need for manual operation, significantly reducing labor intensity and improving cleaning efficiency. The connecting rod in the cleaning assembly has a telescopic function, which, together with the first and second torsion springs, allows the brush head 700 to adapt to insulator surfaces of different shapes and sizes, ensuring good contact between the brush head 700 and the insulator surface during cleaning and improving the cleaning effect.

[0031] like Figure 3 As shown, the connecting rod includes a first connecting rod 112 and a second connecting rod 113. One end of the first connecting rod 112 is fixed to the mounting post 500. The second connecting rod 113 is slidably disposed inside the first connecting rod 112. A spring 114 is disposed inside the first connecting rod 112. One end of the spring 114 abuts against the inner wall of the first connecting rod 112, and the other end of the spring 114 abuts against the end of the second connecting rod 113.

[0032] like Figure 3 As shown, the end of the connecting rod is provided with a first mounting hole, and one end of the rotating column 600 is provided with a second mounting hole. The second mounting hole cooperates with the first mounting hole to install the first rotating shaft 115. The first torsion spring is provided on the first rotating shaft 115. The other end of the rotating column 600 is provided with a third mounting hole, and the brush head 700 is provided with a fourth mounting hole. The third mounting hole cooperates with the fourth mounting hole to install the second rotating shaft 116. The second torsion spring is provided on the second rotating shaft 116.

[0033] Two sets of rotating columns 600 and brush heads 700 are provided at the end of the connecting rod.

[0034] Furthermore, two sets of rotating columns 600 and brush heads 700 are respectively located on both sides of the end of the second connecting rod 113.

[0035] Multiple sets of connecting rods, mounting posts 500, and cleaning components are provided, and these multiple sets of connecting rods, mounting posts 500, and cleaning components are evenly arranged on the mounting posts 500.

[0036] Specifically, since the surface of the insulator may have irregular shapes, the second torsion spring allows the brush head 700 to rotate relative to the rotating column 600 to adapt to the shape changes of the insulator surface; at the same time, the first torsion spring allows the rotating column 600 to rotate relative to the connecting rod, further improving the adaptability of the brush head 700.

[0037] Specifically, the first torsion spring is sleeved on the first rotating shaft 115, and its two ends are respectively fixed to the end of the second connecting rod 113 and one end of the rotating column 600. When the first torsion spring is installed, it can be pre-adjusted to a neutral position perpendicular to the connecting rod to ensure that the rotating column 600 is in a balanced state when there is no external force, and can swing in both directions after contacting the insulator.

[0038] Specifically, the second torsion spring is sleeved on the second rotating shaft 116, and the two ends of the second torsion spring are respectively fixed to the other end of the rotating column 600 and the brush head 700.

[0039] When the insulator diameter is large, the second connecting rod 113 retracts into the first connecting rod 112 under the action of the spring 114. At this time, the first torsion spring adjusts the angle of the rotating column 600 through elastic swing, so that the brush head keeps radially in contact.

[0040] When there are local protrusions on the surface of the insulator, the brush head 700 is compressed and rotates through the second torsion spring, while simultaneously driving the rotating column 600 to swing through the first torsion spring, thus achieving two-dimensional adaptive bonding (radial + circumferential).

[0041] A drive motor 800 is mounted on the side of the base plate 100. A drive gear 900 is mounted on the output shaft of the drive motor 800. The drive gear 900 meshes with a rotating gear 300, and the drive motor 800 drives the rotating gear 300 to rotate through the drive gear 900. A fixing post is mounted on the surface of the rotating gear 300, and a fixing hole is provided in the middle of the fixing post for mounting the connecting post 400.

[0042] Furthermore, the fixing column is made of technical materials (such as aluminum alloy or steel) and is fixedly mounted on the rotating gear 300 (e.g., by welding).

[0043] A support assembly is provided at the other end of the mounting column 500. The support assembly is used to support the mounting column 500 so that the mounting column 500 remains stable during rotation. The support assembly includes a support plate 110 and a roller 111. The upper end of the support plate 110 is fixedly connected to the mounting column 500, and the roller 111 is located at the lower end of the support plate 110 and contacts the intermediate shaft 200.

[0044] Furthermore, the support components are configured to support the mounting column 500 via the support plate 110 and rollers 111, ensuring that the mounting column 500 remains stable during rotation, reducing swaying, and guaranteeing the stability and reliability of the cleaning process.

[0045] Furthermore, the setup of multiple cleaning components allows for simultaneous cleaning of multiple parts of the insulator, expanding the cleaning range, increasing the cleaning speed, and achieving comprehensive and efficient cleaning of the insulator surface. This avoids the safety risks of manual high-altitude operations and enables automatic cleaning through mechanical structures, thereby improving the safety and reliability of the cleaning process.

[0046] Working principle: In use, the insulator is installed on the intermediate shaft 200, and the drive motor 800 is started. The drive motor 800 drives the rotating gear 300 to rotate via the drive gear 900, and the rotating gear 300 drives the maintenance device body to rotate. During the rotation, the cleaning component rotates around the insulator, and the brush on the brush head 700 contacts the surface of the insulator to clean the surface.

[0047] When the brush head 700 contacts the insulator surface, due to the potential irregular shape of the insulator surface, the second torsion spring allows the brush head 700 to rotate relative to the rotating column 600, adapting to changes in the insulator surface shape. Simultaneously, the first torsion spring allows the rotating column 600 to rotate relative to the connecting rod, further enhancing the adaptability of the brush head 700. The second connecting rod 113 in the connecting rod, under the action of the spring 114, can extend and retract according to the diameter of the insulator, allowing the brush head 700 to better conform to the insulator surface. The roller 111 in the support assembly rolls along the intermediate shaft 200, providing stable support for the mounting column 500 and ensuring the smoothness of the mounting column 500 during rotation.
