[0035] In the prior art, the insulator of the transmission line is a kind of high-voltage electrical equipment in the substation. The insulator is installed outdoors. After years of operation, there is dirt on its surface. The dirt may cause the insulator to flash over in a humid weather environment, causing damage to the transmission line. At present, the cleaning of the insulator is carried out manually or by a cleaning device. However, the existing cleaning device realizes the lifting and lowering of the cleaning device through a clamping member, and uses a cleaning brush to rotate along the guide rail to clean the insulator. The cleaning speed is slow, and the cleaning device has a large structural size and a complex structure, which is not conducive to the carrying and installation of the cleaning device. In the related art, the insulator is a plurality of monomers stacked along its axial direction. In some types of insulators, the insulator is formed by alternatingly stacking monomers with a large and a small inner diameter, and the wall surface of the insulator monomer is umbrella-shaped, resulting in uneven force on the clamping member of the cleaning device in the prior art, and the existing cleaning device overlaps multiple monomers of the insulator, resulting in a long overlapping path between the cleaning device and the insulator, which increases the risk of the cleaning device being broken down by high voltage, and further leads to safety hazards of the cleaning device. To this end, some embodiments of the present invention propose an insulator cleaning device, with specific reference to Figures 1 to 8 The insulator cleaning device will be described.

[0036] Reference Figure 1 to Figure 2 The embodiment of the present invention provides an insulator cleaning device, which is applied to an insulator 400, and includes a frame 100, a cleaning mechanism 200 and a climbing drum 300. The frame 100 is enclosed at the outer periphery of the insulator 400. The cleaning mechanism 200 is arranged on the frame 100, and the cleaning mechanism 200 is provided with a cleaning brush 210, which is rotatably connected to the frame 100, and the cleaning brush 210 is driven to rotate along the circumferential direction of the cleaning brush 210, that is, when the cleaning brush 210 can be driven to rotate, the cleaning brush 210 can clean the wall surface of the insulator 400. The insulator 400 is formed by stacking a plurality of monomers 410, and the cleaning brush 210 can extend between two adjacent monomers 410 to clean the outer wall of the insulator 400, thereby improving the cleaning effect. At least three climbing drums 300 are provided, and the central axes of at least three climbing drums 300 are respectively rotatably connected to the frame 100, so that the climbing drum 300 can be driven to rotate. The central axis of the climbing drum 300 is inclined relative to the central axis of the insulator 400 , and at least three climbing drums 300 are respectively in contact with the outer peripheral wall of the insulator 400 .

[0037] It can be understood that the climbing roller 300, the insulator 400 and the cleaning brush 210 are respectively 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 can be understood that when at least three climbing rollers 300 are driven to rotate, since 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 are spirally ascended along the outer peripheral wall of the insulator 400, driving the cleaning mechanism 200 to spirally ascend along the outer peripheral wall of the insulator 400, and at the same time, the cleaning brush 210 is driven to rotate along the circumference of the cleaning brush 210, so that the cleaning brush 210 can spirally ascend along the outer peripheral wall of the insulator 400 while rotating to clean the insulator 400. When at least three climbing rollers 300 are driven to rotate, they can spirally ascend along the outer peripheral wall of the insulator 400, so that the insulator cleaning device as a whole can spirally ascend along the outer peripheral wall of the insulator 400, so that the cleaning brush 210 can spirally ascend along the outer peripheral wall of the insulator 400 while rotating to clean the insulator 400, thereby improving the ascending speed of the insulator cleaning device relative to the insulator 400, thereby improving the cleaning efficiency of the insulator 400. Since the cleaning mechanism 200 can spirally rise along the outer wall of the insulator 400, the cleaning coverage of the cleaning brush 210 relative to the insulator 400 is improved, thereby improving the cleaning effect. At the same time, there is no need to set a moving guide rail for the cleaning brush 210 on the frame 100, which simplifies the structure of the frame 100, reduces the difficulty of processing and installation, and improves the portability of the insulator cleaning device.

[0039] Reference Figure 1 and Figure 2 It can be understood that, since at least three climbing rollers 300 are respectively in contact with the outer peripheral wall of the insulator 400, at least three climbing rollers 300 are simultaneously in contact with the outer peripheral wall of the same monomer 410, thereby making the connection between the climbing roller 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 being separated from the insulator 400.

[0040] It is understandable that in some embodiments of the present invention, the climbing drum 300 is simultaneously in contact with two adjacent monomers 410, which reduces the overlap length of the insulator cleaning device and the insulator 400, that is, it avoids the insulator cleaning device from having an excessively long overlap path relative to the insulator 400, reduces the risk of the insulator cleaning device being damaged by high voltage breakdown, and enables the insulator cleaning device of the present invention to be adapted to the cleaning scene of the insulator 400 with high voltage, thereby improving the safety and applicability of the insulator cleaning device. At the same time, since at least three climbing drums 300 are simultaneously overlapped with two adjacent monomers 410, the connection between the insulator cleaning device and the insulator 400 is more stable.

[0041] It can be understood that when the insulator 400 in the prior art is an alternating arrangement of monomers 410 with a larger inner diameter and a smaller inner diameter, the at least three climbing rollers 300 in the present invention can simultaneously abut against two adjacent monomers 410 with a larger inner diameter, thereby ensuring the reliability and safety of the insulator cleaning device in the present invention.

[0042] Reference Figure 8 In some embodiments of the present invention, the outer peripheral wall of the climbing drum 300 is provided with a connecting layer 310, and the connecting layer 310 abuts against the insulator 400. The connecting layer 310 is used to improve the adhesion between the climbing drum 300 and the insulator 400, so that the connection between at least three climbing drums 300 and the insulator 400 is more stable, thereby improving the installation stability of the insulator cleaning device. It is understandable that the connecting layer 310 can be made of rubber material, and the rubber material can be deformed to make the contact between the climbing drum 300 and the insulator 400 closer, thereby improving the adhesion between the climbing drum 300 and the insulator 400. At the same time, rubber has insulating properties, which reduces the risk of the insulator cleaning device being broken down and damaged. The connecting layer 310 can also be made of materials such as silicone rubber, which can be selected according to actual applications, and the present application is not limited here.

[0043] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the rack 100 includes at least three groups of detachably connected connection frames 110, and the at least three groups of connection frames 110 are sequentially connected and arranged along the circumference of the insulator 400. Since the at least three groups of connection frames 110 are detachably connected, the efficiency of installation and removal of the rack 100 is improved, and the convenience of installation and removal is improved. At the same time, if one group of connection frames 110 is damaged, the connection frame 110 can be replaced separately without replacing the entire rack 100, 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, and the control device 500 is used to control the climbing drum 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 installed at the first mounting position 111, the climbing drum 300 is installed at the second mounting position 112, and the control device 500 is installed at the third mounting position 113. The cleaning mechanism 200, the climbing drum 300 and the control device 500 are arranged on a single connecting frame 110, and the control device 500 can control the cleaning mechanism 200 and the climbing drum 300, so that the single connecting frame 110 is modularized, that is, at least three groups of connecting frames 110 are connected to form an insulator cleaning device, which improves the integration of the connecting frame 110, improves the installation and disassembly efficiency of the insulator cleaning device, and the insulator cleaning device can independently maintain and replace the equipment in the connecting frame 110, saving maintenance costs and time.

[0045] It is understandable that the number of connecting frames 110 in the insulator cleaning device can be three or more, and can be flexibly adjusted according to the maximum outer diameter of the insulator 400, or can be selected according to actual applications, and 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 installed at the first installation position 111 and is used to drive the cleaning brush 210 to rotate along the circumferential direction of the cleaning brush 210. The climbing drum 300 is connected with a second driving device 320, which is installed at the second installation position 112 and is used to drive the climbing drum 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, and further control the rotation of the cleaning brush 210 and the climbing drum 300. By providing the control device 500 on the connecting frame 110, the insulator cleaning device does not need an external power supply 520, which reduces the dependence of the insulator cleaning device on the external environment and improves 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, which reduces the production difficulty of the connecting frame 110 and improves the production efficiency. The connecting frame 110 is also provided with an installation bin 118, the two ends of the installation bin 118 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 bin 118. The first mounting position 111 and the second mounting position 112 are respectively located on both sides of the support column 116, and the third mounting position 113 is arranged in the mounting bin 118, and the mounting bin 118 is located on the side of the second mounting position 112 away from the first mounting position 111, thereby optimizing the stress distribution of the connecting frame 110 and improving 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, the two sets of mounting plates 117 are respectively located on the first support plate 114 and the second support plate 115, and the second driving device 320 is installed on one of the mounting plates 117. The two sets of mounting plates 117 are inclined relative to the axis direction of the insulator 400, and the two ends of the climbing drum 300 are respectively rotatably connected to the two sets of mounting plates 117, so that the central axis of the climbing drum 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 groups 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 groups of cleaning brushes 210 are rotatably connected to the first support plate 114 and the second support plate 115, respectively. By arranging two groups of cleaning brushes 210 along the axial direction of the insulator 400, the cleaning tracks of the two groups of cleaning brushes 210 along the axial direction of the insulator 400 overlap, thereby improving the cleaning coverage rate, thereby improving the cleaning efficiency and cleanliness. The first driving device 220 is installed at the first installation position 111, and the first driving device 220 is installed on the side wall of the support column 116. The two groups of cleaning brushes 210 are respectively connected to the first driving device 220, so that the two groups of cleaning brushes 210 are driven by one first driving device 220, thereby improving the energy utilization rate of the first driving device 220, reducing the cost and space occupation of the equipment, and improving the synchronization rate of the two groups of cleaning brushes 210. Along the axial direction of the insulator 400 , two groups 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 of the structure inside the frame 100 limiting the volume of the cleaning brushes 210 .

[0050] It is understandable that the climbing roller 300 is rotatably connected to the mounting plate 117, which can be achieved through bearings, and the two sets of cleaning brushes 210 are respectively rotatably connected to the first support plate 114 and the second support plate 115, which can also be achieved through bearings. The rotation connection is achieved through bearings, which improves the stability of the rotation of the climbing roller 300 and the cleaning brush 210. The rotation connection can also be achieved through pins and holes, etc., which can be selected according to actual production applications, and this application is not limited here.

[0051] Reference Figure 4 , Figure 5 and Figure 6 In some embodiments of the present invention, three groups of connection frames 110 are provided. The three groups of connection frames 110 are sequentially connected along the circumference of the insulator 400. The three groups of connection frames 110 are respectively a first frame 120, a second frame 130 and a third frame 140. A mounting portion 121 is provided at one end of the first frame 120, and a mounting groove 141 is provided at one end of the third frame 140. The mounting portion 121 is buckled in the mounting groove 141. The mounting portion 121 is directly buckled in the mounting groove 141, so that the first frame 120 and the second frame 130 are detachably connected, which improves 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 a mounting groove 141. Two groups of mounting parts 121 are provided, and the two groups of mounting parts 121 are respectively located in the mounting chamber 118 of the first frame 120, and the two groups of mounting parts 121 are located on both sides of the mounting chamber 118 along the axis direction of the insulator 400. The mounting groove 141 includes a guide groove 1412 and a connecting groove 1411 that are connected to each other. The connecting groove 1411 extends along the circumferential direction of 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 part 121 can directly enter the guide groove 1412 from the side wall of the first support plate 114, and then enter and buckle with the connecting groove 1411 through the guide groove 1412.

[0053] It is understandable that in some embodiments of the present invention, 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 buckle with the connecting groove 1411, which further improves the convenience of installation and removal of the first frame 120 and the third frame 140. Since the connecting groove 1411 extends along the circumference of 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 of the frame 100, and then the pre-tightening force of at least three climbing drums 300 and the insulator 400 can be adjusted, thereby 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. At the same time, since the insulator cleaning device can adjust the inner diameter of the frame 100, the insulator cleaning device can adapt to the maximum outer diameter of different insulators 400, thereby improving the applicability of the insulator cleaning device and allowing a certain error in the production of the insulator cleaning device, thereby reducing the processing difficulty.

[0054] Reference Figure 5 and Figure 6It can be understood that, in some embodiments of the present invention, the mounting portion 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 screw in the guide groove 1412 is adjusted to adjust the pre-tightening force of the insulator cleaning device connected to the insulator 400. After the pre-tightening force of the insulator cleaning device is adjusted, the locking screw is adjusted to move along the height direction of the mounting chamber 118, so that the two sets of locking screws are pressed against the first support plate 114 and the second support plate 115 respectively, so that the first frame 120 and the third frame 140 are fixedly connected to complete the installation of the insulator cleaning device on the insulator 400. Since the locking screw is threadedly connected to the mounting chamber 118, it is convenient to adjust the locking screw to move along the height direction of the mounting chamber 118, thereby improving the convenience 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 and the second support plate 115, thereby facilitating the locking screw to enter the mounting groove 141, thereby improving the convenience and efficiency of installation.

[0055] It is understandable that the mounting portion 121 may also be a pin or other mechanical structure, which is not limited in the present application. 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 portion 121 is located at one end of the first frame 120 away from the second frame 130, and the mounting groove 141 is located at one end of the third frame 140 away from the second frame 130. The two ends of the second frame 130 are respectively hinged to the first frame 120 and the third frame 140, so that the second frame 130 can rotate relative to the first frame 120 and the third frame 140. Since the two ends of the second frame 130 are respectively hinged to the first frame 120 and the third frame 140, the first frame 120 and the third frame 140 are buckled to the mounting groove 141 through the mounting portion 121, so that after the mounting portion 121 and the mounting groove 141 are disassembled, the insulator cleaning device can be unfolded into a chain structure, so that it can be disassembled and laid flat when not in use, thereby improving the portability of the insulator cleaning device. During installation and use, the insulator cleaning device is enclosed in the outer wall of the insulator 400, and the mounting portion 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 portion 121 in the connecting groove 1411 and the preload force between the insulator cleaning device and the insulator 400, the first frame 120 and the third frame 140 are fixedly connected by the mounting portion 121, so that the insulator cleaning device is installed on the insulator 400, thereby improving the convenience and efficiency of installation and disassembly of the insulator cleaning device.

[0056] It can be understood that in other embodiments of the present invention, the first frame 120 and the second frame 130 are snap-connected via the mounting portion 121 and the mounting groove 141, and the second frame 130 and the third frame 140 are snap-connected via the mounting portion 121 and the mounting groove 141, thereby improving the adjustable range of the enclosed inner diameter of the insulator cleaning device. At the same time, since the mounting portion 121 and the mounting groove 141 between any two groups of the first frame 120, the second frame 130 and the third frame 140 can be quickly disassembled, the flexibility and convenience of disassembly of the insulator cleaning device are improved.

[0057] It is understandable that by controlling the climbing drum 300 to rotate in a clockwise or counterclockwise direction, the insulator cleaning device can be controlled to move in a spiral upward or downward motion along the outer peripheral wall of the insulator 400. When the insulator cleaning device cleans the insulator 400, the insulator cleaning device can clean from below the insulator 400 along its axial direction with a spiral upward motion trajectory. After cleaning, by controlling the climbing drum 300 to rotate in the opposite direction to that during cleaning, the insulator cleaning device returns to the initial installation position with a spiral downward motion trajectory, which is convenient for personnel to disassemble. The initial installation position of the insulator cleaning device and the disassembly position after cleaning can be selected according to actual application, and this application is not limited here.
