The frame surrounds the outer periphery of the insulator. The cleaning mechanism is mounted on the frame and includes a cleaning brush that rotates to clean the insulator's outer surface. At least three climbing rollers are rotatably connected to the frame, with their central axes inclined relative to the insulator's central axis.

[0031] This section will describe in detail specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0032] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0033] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0034] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0035] In existing technology, insulators of transmission lines are high-voltage electrical equipment in substations. Installed outdoors, these insulators accumulate dirt on their surfaces during years of operation. This dirt can cause flashover in humid weather conditions, leading to damage to the transmission lines. Currently, insulators are cleaned manually or using cleaning devices. However, existing cleaning devices use clamps to lift and lower the device, and a cleaning brush rotates along a guide rail to clean the insulator. This method is slow, and the devices are large and complex, making them difficult to carry and install. In related technologies, insulators are formed by stacking several individual units along their axis. In some types of insulators, the insulators are formed by alternating stacks of units with varying inner diameters, and the walls of the individual insulator units are umbrella-shaped. This results in uneven force on the clamping components of existing cleaning devices. Furthermore, existing cleaning devices overlap multiple insulator units, leading to an excessively long overlap path between the cleaning device and the insulator, increasing the risk of the cleaning device being damaged by high voltage, thus posing a safety hazard. Therefore, some embodiments of this invention propose an insulator cleaning device, which can be found in the following references. Figures 1 to 8 The insulator cleaning device is described.

[0036] Reference Figures 1 to 2 This invention provides an insulator cleaning device for an insulator 400, comprising a frame 100, a cleaning mechanism 200, and climbing rollers 300. The frame 100 surrounds the outer periphery of the insulator 400. The cleaning mechanism 200 is disposed on the frame 100 and includes a cleaning brush 210 rotatably connected to the frame 100. The cleaning brush 210 is driven to rotate circumferentially, meaning that when the cleaning brush 210 is driven to rotate, it can clean the wall surface of the insulator 400. The insulator 400 is composed of several stacked units 410. The cleaning brush 210 can extend between two adjacent units 410 to clean the outer wall of the insulator 400, improving the cleaning effect. At least three climbing rollers 300 are provided, and the central axes of the at least three climbing rollers 300 are rotatably connected to the frame 100, allowing the climbing rollers 300 to be driven to rotate. The central axis of the climbing roller 300 is inclined relative to the central axis of the insulator 400, and at least three climbing rollers 300 abut against the outer peripheral wall of the insulator 400.

[0037] It is understandable that the climbing roller 300, the insulator 400 and the cleaning brush 210 are each provided with a central axis, the direction along the central axis is the axial direction, and the direction around the central axis is the circumferential direction.

[0038] Reference Figure 1 and Figure 2It is understandable that when at least three climbing rollers 300 are driven to rotate, because the central axis of the climbing rollers 300 is inclined relative to the central axis of the insulator 400, the at least three climbing rollers 300 spiral upward along the outer peripheral wall of the insulator 400, driving the cleaning mechanism 200 to spiral upward along the outer peripheral wall of the insulator 400. Simultaneously, the cleaning brush 210 is driven to rotate circumferentially, thus causing the cleaning brush 210 to rotate while spiraling upward along the outer peripheral wall of the insulator 400 to clean the insulator 400. By driving at least three climbing rollers 300 to rotate and spiral upward along the outer peripheral wall of the insulator 400, the entire insulator cleaning device can spiral upward along the outer peripheral wall of the insulator 400, thereby increasing the upward speed of the insulator cleaning device relative to the insulator 400 and thus improving the cleaning efficiency of the insulator 400. Since the cleaning mechanism 200 can spiral upward along the outer peripheral wall of the insulator 400, the cleaning coverage of the cleaning brush 210 relative to the insulator 400 is increased, thereby improving the cleaning effect. At the same time, there is no need to set the motion guide rail of the cleaning brush 210 on the frame 100, which simplifies the structure of the frame 100, reduces the processing and installation difficulty, and improves the portability of the insulator cleaning device.

[0039] Reference Figure 1 and Figure 2 It is understandable that, since at least three climbing rollers 300 abut against the outer peripheral wall of the insulator 400 respectively, at least three climbing rollers 300 abut against the outer peripheral wall of the same unit 410 at the same time, thereby making the connection between the climbing rollers 300 and the insulator 400 more stable, improving the installation stability between the insulator cleaning device and the insulator 400, and reducing the risk of the insulator cleaning device detaching from the insulator 400.

[0040] It is understood that in some embodiments of the present invention, the climbing rollers 300 simultaneously abut against two adjacent individual units 410, reducing the overlap length between the insulator cleaning device and the insulator 400. This avoids an excessively long overlap path between the insulator cleaning device and the insulator 400, reducing the risk of the insulator cleaning device being damaged by high voltage breakdown. This allows the insulator cleaning device of the present invention to be adapted to cleaning scenarios involving energized, high-voltage insulators 400, improving the safety and applicability of the insulator cleaning device. Simultaneously, since at least three climbing rollers 300 simultaneously overlap two adjacent individual units 410, the connection between the insulator cleaning device and the insulator 400 is more stable.

[0041] It is understandable that, in the prior art, when the insulator 400 is an alternating arrangement of single units 410 with different inner diameters, the at least three climbing rollers 300 in this invention can simultaneously abut against two adjacent single units 410 with larger inner diameters, thus ensuring the reliability and safety of the insulator cleaning device in this invention.

[0042] Reference Figure 8 In some embodiments of the present invention, the outer peripheral wall of the climbing roller 300 is provided with a connecting layer 310, which abuts against the insulator 400. The connecting layer 310 is used to improve the adhesion between the climbing roller 300 and the insulator 400, making the connection between at least three climbing rollers 300 and the insulator 400 more stable, thereby improving the installation stability of the insulator cleaning device. It is understood that the connecting layer 310 can be made of rubber. Rubber can deform to make the contact between the climbing roller 300 and the insulator 400 tighter, improving the adhesion between the climbing roller 300 and the insulator 400. At the same time, rubber has insulating properties, reducing the risk of the insulator cleaning device being punctured and damaged. The connecting layer 310 can also be made of materials such as silicone rubber, which can be selected according to the actual application, and this application does not limit it.

[0043] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the frame 100 includes at least three sets of detachably connected connecting frames 110, which are arranged sequentially along the circumference of the insulator 400. Because the at least three sets of connecting frames 110 are detachably connected, the efficiency and convenience of installing and disassembling the frame 100 are improved. Furthermore, if one set of connecting frames 110 is damaged, only that connecting frame 110 can be replaced, eliminating the need to replace the entire frame 100 and saving maintenance costs.

[0044] Reference Figure 3In some embodiments of the present invention, the insulator cleaning device is further provided with a control device 500, which is used to control the climbing roller 300 and the cleaning mechanism 200. The connecting frame 110 includes a first mounting position 111, a second mounting position 112, and a third mounting position 113. The cleaning mechanism 200 is mounted at the first mounting position 111, the climbing roller 300 is mounted at the second mounting position 112, and the control device 500 is mounted at the third mounting position 113. By providing the cleaning mechanism 200, the climbing roller 300, and the control device 500 on a single connecting frame 110, and by enabling the control device 500 to control the cleaning mechanism 200 and the climbing roller 300, the single connecting frame 110 is modularized. That is, at least three sets of connecting frames 110 are connected to form the insulator cleaning device, improving the integration of the connecting frame 110, increasing the installation and disassembly efficiency of the insulator cleaning device, and allowing the insulator cleaning device to independently maintain and replace the equipment in the connecting frame 110, saving maintenance costs and time.

[0045] It is understood that the number of connecting brackets 110 in the insulator cleaning device can be three or more, which can be flexibly adjusted according to the maximum outer diameter of the insulator 400, or selected according to the actual application. This application does not limit this.

[0046] Reference Figure 3 In some embodiments of the present invention, the control device 500 includes a controller 510 and a power supply 520. The cleaning mechanism 200 is provided with a first driving device 220, which is mounted at a first mounting position 111 and is used to drive the cleaning brush 210 to rotate circumferentially. A climbing roller 300 is connected to a second driving device 320, which is mounted at a second mounting position 112 and is used to drive the climbing roller 300 to rotate. The power supply 520 can supply power to the first driving device 220 and the second driving device 320. The controller 510 is used to control the first driving device 220 and the second driving device 320, thereby controlling the rotation of the cleaning brush 210 and the climbing roller 300. By providing the control device 500 on the connecting frame 110, the insulator cleaning device does not require an external power supply 520, reducing the insulator cleaning device's dependence on the external environment and improving the independence and portability of the insulator cleaning device.

[0047] Reference Figure 3 , Figure 4 and Figure 6In some embodiments of the present invention, the connecting frame 110 includes a first support plate 114, a second support plate 115, and a support column 116. The first support plate 114 and the second support plate 115 are arranged at intervals along the axial direction of the insulator 400, and the two ends of the support column 116 are respectively connected to the first support plate 114 and the second support plate 115. By including the first support plate 114, the second support plate 115, and the support column 116, the structure of the connecting frame 110 is simplified, the portability of the frame 100 is improved, and the assembly of the connecting frame 110 is facilitated. The first support plate 114 and the second support plate 115 can be produced by sheet metal, reducing the production difficulty of the connecting frame 110 and improving production efficiency. The connecting frame 110 is also provided with an installation chamber 118, the two ends of which are respectively connected to the first support plate 114 and the second support plate 115, and the control device 500 is installed in the installation chamber 118. The first mounting position 111 and the second mounting position 112 are located on both sides of the support column 116, and the third mounting position 113 is located in the mounting chamber 118. The mounting chamber 118 is located on the side of the second mounting position 112 away from the first mounting position 111, which optimizes the stress distribution of the connecting frame 110 and improves the structural strength of the connecting frame 110.

[0048] Reference Figure 3 and Figure 7 In some embodiments of the present invention, the second mounting position 112 is provided with two sets of mounting plates 117, which are respectively located on the first support plate 114 and the second support plate 115. The second driving device 320 is mounted on one of the mounting plates 117. The two sets of mounting plates 117 are inclined relative to the axial direction of the insulator 400. The two ends of the climbing roller 300 are rotatably connected to the two sets of mounting plates 117, so that the central axis of the climbing roller 300 is inclined relative to the central axis of the insulator 400, which simplifies the structure of the connecting frame 110 and improves the portability of the connecting frame 110. The two sets of mounting plates 117 located on the first support plate 114 and the second support plate 115 can be produced by sheet metal processing, which reduces the processing difficulty and improves the production efficiency of the connecting frame 110.

[0049] Reference Figure 3 and Figure 7In some embodiments of the present invention, the cleaning mechanism 200 includes two sets of cleaning brushes 210 and a first driving device 220. The cleaning brushes 210 are rotatably connected to the connecting frame 110, and the two sets of cleaning brushes 210 are rotatably connected to the first support plate 114 and the second support plate 115, respectively. By arranging two sets of cleaning brushes 210 along the axial direction of the insulator 400, the cleaning trajectories of the two sets of cleaning brushes 210 along the axial direction of the insulator 400 overlap, thereby improving the cleaning coverage, and thus improving the cleaning efficiency and cleanliness. The first driving device 220 is installed at the first mounting position 111 and on the side wall of the support column 116. The two sets of cleaning brushes 210 are respectively connected to the first driving device 220, so that the two sets of cleaning brushes 210 are driven by one first driving device 220, which improves the energy utilization rate of the first driving device 220, reduces the cost and space occupation of the equipment, and improves the synchronization rate of the two sets of cleaning brushes 210. Along the axial direction of the insulator 400, two sets of cleaning brushes 210 are located on both sides of the frame 100, ensuring that the cleaning brushes 210 have sufficient installation space and reducing the risk that the internal structure of the frame 100 restricts the volume of the cleaning brushes 210.

[0050] It is understood that the climbing roller 300 is rotatably connected to the mounting plate 117, which can be achieved through bearings. Similarly, the two sets of cleaning brushes 210 are rotatably connected to the first support plate 114 and the second support plate 115, respectively, also via bearings. Using bearings for the rotatable connection improves the smoothness of the rotation of the climbing roller 300 and the cleaning brushes 210. The rotatable connection can also be achieved through pins and holes, etc., which can be selected according to the actual production application; this application does not impose any limitations on this.

[0051] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments of the present invention, the connecting frame 110 is provided in three sets, which are connected sequentially along the circumference of the insulator 400. The three sets of connecting frames 110 are respectively a first frame 120, a second frame 130, and a third frame 140. One end of the first frame 120 is provided with a mounting part 121, and one end of the third frame 140 is provided with a mounting groove 141, with the mounting part 121 fastened to the mounting groove 141. By directly fastening the mounting part 121 to the mounting groove 141, the first frame 120 and the second frame 130 are detachably connected, improving the convenience of installation and disassembly between the first frame 120 and the third frame 140, thereby improving the installation and disassembly efficiency of the insulator cleaning device.

[0052] Reference Figure 4 and Figure 5In some embodiments of the present invention, the first support plate 114 and the second support plate 115 of the third frame 140 are respectively provided with mounting grooves 141. Two sets of mounting portions 121 are provided, each set located in the mounting chamber 118 of the first frame 120, with the two sets of mounting portions 121 located on both sides of the mounting chamber 118 along the axial direction of the insulator 400. The mounting groove 141 includes a guide groove 1412 and a connecting groove 1411 that communicate with each other. The connecting groove 1411 extends circumferentially along the insulator 400. The guide groove 1412 located on the first support plate 114 extends from the side wall of the first support plate 114 to the connecting groove 1411, and the guide groove 1412 located on the second support plate 115 extends from the side wall of the second support plate 115 to the connecting groove 1411. The mounting portion 121 can directly enter the guide groove 1412 from the side wall of the first support plate 114, and then enter and engage with the connecting groove 1411 through the guide groove 1412.

[0053] It is understood that, in some embodiments of the present invention, the two sets of mounting parts 121 can enter the guide groove 1412 from the side walls of the first support plate 114 and the second support plate 115, and then enter the connecting groove 1411 and be fastened to the connecting groove 1411, further improving the convenience of installation and disassembly of the first frame 120 and the third frame 140. Since the connecting groove 1411 extends circumferentially along the insulator 400, the installation position of the mounting part 121 relative to the connecting groove 1411 can be adjusted to adjust the inner diameter enclosed by the frame 100, thereby adjusting the preload of at least three climbing rollers 300 and the insulator 400, improving the stability of the connection between the insulator cleaning device and the insulator 400, and improving the reliability and safety of the insulator cleaning device. Meanwhile, since the insulator cleaning device can adjust the inner diameter of the frame 100, it can adapt to the maximum outer diameter of different insulators 400, which improves the applicability of the insulator cleaning device and allows for certain errors in the manufacturing process, thus reducing the processing difficulty.

[0054] Reference Figure 5 and Figure 6It is understood that in some embodiments of the present invention, the mounting part 121 is a locking screw, and the locking screw is threadedly connected to the mounting chamber 118. When the insulator cleaning device is installed on the insulator 400, the two sets of locking screws are directly inserted into the guide groove 1412 from the side walls of the first support plate 114 and the second support plate 115, and then enter the connecting groove 1411 through the guide groove 1412. The relative position of the locking screws in the guide groove 1412 is adjusted to adjust the preload of the insulator cleaning device connected to the insulator 400. After the preload of the insulator cleaning device is adjusted, the locking screws are moved along the height direction of the mounting chamber 118 so that the two sets of locking screws press against the first support plate 114 and the second support plate 115 respectively, thereby fixing the first frame 120 and the third frame 140 together to complete the installation of the insulator cleaning device on the insulator 400. Because the locking screw is threadedly connected to the mounting chamber 118, it is easy to adjust the movement of the locking screw along the height direction of the mounting chamber 118, thus improving the ease of operation. Since the guide groove 1412 extends from the side wall of the first support plate 114 or the second support plate 115 to the connecting groove 1411, the locking screw can be directly inserted into the guide groove 1412 from the side wall of the first support plate 114 or the second support plate 115, facilitating the entry of the locking screw into the mounting groove 141, thereby improving the ease and efficiency of installation.

[0055] It is understood that the mounting part 121 could also be other mechanical structures such as a pin, and this application does not limit this to any particular type. (See reference...) Figure 6 and Figure 7 In some embodiments of the present invention, the two ends of the second frame 130 are respectively hinged to the first frame 120 and the third frame 140. The mounting part 121 is located at the end of the first frame 120 away from the second frame 130, and the mounting groove 141 is located at the end of the third frame 140 away from the second frame 130. By hinged to the two ends of the second frame 130, the second frame 130 can rotate relative to the first frame 120 and the third frame 140 respectively. Since the two ends of the second frame 130 are respectively hinged to the first frame 120 and the third frame 140, and the first frame 120 and the third frame 140 are fastened to the mounting groove 141 by the mounting part 121, the insulator cleaning device can be unfolded into a chain structure after the mounting part 121 and the mounting groove 141 are disassembled. This allows the device to be disassembled and laid flat when not in use, improving the portability of the insulator cleaning device. During installation and use, the insulator cleaning device is surrounded on the outer periphery of the insulator 400. The mounting part 121 of the first frame 120 enters the connecting groove 1411 from the guide groove 1412 of the third frame 140. After adjusting the position of the mounting part 121 in the connecting groove 1411 and adjusting the pre-tightening force between the insulator cleaning device and the insulator 400, the first frame 120 and the third frame 140 are fixedly connected through the mounting part 121, so that the insulator cleaning device can be installed on the insulator 400, which improves the convenience and efficiency of the installation and disassembly of the insulator cleaning device.

[0056] It is understood that in some other embodiments of the present invention, the first frame 120 and the second frame 130 are fastened together by the mounting part 121 and the mounting groove 141, and the second frame 130 and the third frame 140 are fastened together by the mounting part 121 and the mounting groove 141. This improves the adjustable range of the inner diameter of the insulator cleaning device. At the same time, since the mounting part 121 and the mounting groove 141 between any two sets of the first frame 120, the second frame 130 and the third frame 140 can be quickly disassembled, the flexibility and convenience of disassembling the insulator cleaning device are improved.

[0057] It is understood that by controlling the climbing roller 300 to rotate clockwise or counterclockwise, the insulator cleaning device can be controlled to spiral upward or downward along the outer peripheral wall of the insulator 400. When cleaning the insulator 400, the insulator cleaning device can clean from below the insulator 400 along its axial direction in a spiral upward trajectory. After cleaning, by controlling the climbing roller 300 to rotate in the opposite direction to the cleaning, the insulator cleaning device returns to its initial installation position in a spiral downward trajectory, facilitating disassembly. The initial installation position and the disassembly position of the insulator cleaning device after cleaning can be selected based on actual application, and this application does not impose any limitations on them.
