Description

Technical Field

[0001] This invention relates to the field of subway insulator cleaning technology, specifically a rotary cleaning device for subway rigid contact network insulators. Background Technology

[0002] As a crucial component of the power supply system, subway overhead contact line equipment is exposed to relatively humid and dusty environments due to limited ventilation. Prolonged operation easily leads to dust accumulation on the surface of the contact line insulators. If not cleaned promptly, the safe creepage distance shortens, and in extreme cases, flashover can easily occur. Currently, in the daily maintenance of subway line equipment, traditional methods require workers to use ladder trucks to climb to the height of the contact line busbars, directing ground personnel to push the ladder trucks along the busbars to the contact line insulators, where they use cleaning tools such as scouring pads to clean and wipe the insulator surfaces. However, traditional cleaning processes have many drawbacks: at least six people are needed to push the ladder trucks, resulting in excessive manpower and wasted resources; and the efficiency of manual cleaning gradually decreases over time, leading to low work efficiency. Summary of the Invention

[0003] To achieve the above objectives, the present invention provides the following technical solution: a rotary cleaning device for rigid contact wire insulators in subway systems, comprising a suspension body, a lithium battery mounted on the front bottom of the suspension body to provide power to a receiving module and a cleaning motor, a receiving module mounted on the rear bottom of the suspension body to cooperate with a remote control module to control the operation of the drive wheel and cleaning components, a main beam plate mounted between the lithium battery and the receiving module, and the top of the main beam plate being assembled with the suspension body by bolts, and a square through slot penetrating the center of the top of the suspension body, with a hopper fitted inside the square through slot to prevent the cleaning device from being used by the insulator. Over time, dust accumulates directly on the lithium battery, hindering its normal heat dissipation. The suspension body is mounted on the main beam plate, with a crossbeam plate running through its front center. Seat plates are bolted to the bottom of both ends of the crossbeam plate. The front end of the crossbeam plate is combined with the lithium battery via bolts and seat plates, while the rear end is combined with the receiving module via bolts and seat plates. The receiving module is electrically connected to a remote control module, enabling remote control of the cleaning components to clean the insulators and control of the drive wheels to move forward and backward on the rigid contact wire. This remote operation is convenient.

[0004] It also includes drive rubber wheels, which are symmetrically installed on both sides of the front end of the suspension body. The drive rubber wheels include first corner plates that are bolted to both sides of the suspension body. A stepper motor is fixedly installed on the vertical plate of the first corner plate. An active rubber wheel is installed on the vertical plate of the first corner plate on the side facing away from the stepper motor. The active rubber wheel is rotatably installed with the first corner plate via the stepper motor.

[0005] The cleaning component is installed on the top of the suspension body and symmetrically on the middle of the left and right sides of the suspension body. The cleaning component includes an inner folding plate. The bottom plate of the inner folding plate has hexagonal holes at equal intervals. A long screw is threaded into the inner side of the hexagonal holes. The inner folding plate is threaded to the suspension body through the long screw. It can dissipate heat from the bottom of the sweeping motor downwards in the opposite direction with the help of the long screw, thereby improving the heat conduction efficiency of the inner folding plate and providing auxiliary heat dissipation.

[0006] Preferably, a first auxiliary support plate is installed at the end of the first corner plate near the lithium battery. An auxiliary top rubber wheel is rotatably installed on the vertical plate of the first auxiliary support plate and is located on the same plane as the active rubber wheel. A bottom-covering folding plate is installed at the end of the first auxiliary support plate near the first corner plate and is located at the front bottom of the suspension body. It is bolted to the bottom of the horizontal plate of the first corner plate to enhance the installation strength of the bottom of the first corner plate on the suspension body. At the same time, the side wall of the bottom-covering folding plate is used to block the back-and-forth swaying of the small folding plate.

[0007] Preferably, the first auxiliary support plate includes a small folded plate, which is bolted to the bottom of the front end of the suspension body. A hook plate is hinged to the inclined side wall of the vertical plate of the small folded plate. A notch and a groove are provided on the inclined side of the vertical plate of the small folded plate. The groove is located above the notch, and the hook plate is hooked to the small folded plate through the groove. Protrusions are installed at equal intervals on the inner side wall of the notch to prevent the large insertion rod from loosening inside the notch during use, thus ensuring the smooth sliding of the auxiliary top rubber wheel within the bottom track of the rigid contact wire.

[0008] Preferably, a large insert rod is installed in the middle of the inner side of the notch, and a washer is fixedly installed on the outer surface of the large insert rod. A swing plate is installed on the side of the small folding plate away from the auxiliary top rubber wheel. A limiting rail is opened through the surface of the swing plate. The large insert rod passes through the limiting rail and is inserted into the swing plate. It is assembled with the swing plate by the cooperation of a nut and a washer. The washer is limited and installed between the vertical plate of the swing plate and the small folding plate. By fastening the hook plate to the inside of the groove, a second layer of anti-sway interception protection can be provided for the fixed installation of the large insert rod inside the notch.

[0009] Preferably, a fixed pin is rotatably installed at the middle of the end of the swing plate away from the pad ring, and the end of the fixed pin away from the swing plate is inserted into the vertical plate of the small folding plate. The swing plate is rotatably installed with the small folding plate through the fixed pin. The initial installation position of the swing plate equipped with the auxiliary top rubber wheel is located on the side wall of the small folding plate and away from the first corner plate.

[0010] Preferably, an assembly pin is inserted at the end of the auxiliary top rubber wheel away from the small folding plate. The assembly pin passes through the auxiliary top rubber wheel and is threadedly connected to the large insertion rod. The auxiliary top rubber wheel is rotated and installed with the small folding plate through the cooperation of the assembly pin and the large insertion rod. Through the connection and assembly relationship between the above structures, the drive rubber wheel can be quickly assembled on the rigid contact wire, which facilitates the assembly of the cleaning equipment on the rigid contact wire.

[0011] Preferably, a first eave and a second eave are fixedly connected to the vertical plate of the inner folding plate, and the first eave is located between the bottom plate of the inner folding plate and the second eave. Both the first eave and the second eave have an opening in the middle of their arc-shaped sides. A buckle is fixedly connected to the vertical plate of the inner folding plate and is located between the bottom plate of the inner folding plate and the first eave. A cleaning motor is fitted inside the buckle. The output end of the cleaning motor is inserted into the opening at the top of the first eave, so as to avoid the cleaning rod from accidentally tilting and causing scratching of the insulator, thus ensuring the safety of the insulator.

[0012] Preferably, a telescopic rod is installed at the top of the first eaves and connected to the output end of the sweeping motor at the bottom. The non-telescopic end of the telescopic rod is fitted into the inner side of the second eaves through an opening. The telescopic end of the telescopic rod extends from the top through an opening on the second eaves. A threaded rod is threaded to the telescopic end of the telescopic rod. A sweeping rod is threaded to the outer surface of the threaded rod. Nylon filaments are installed on the outer surface of the sweeping rod and are tied to the sweeping rod in layers. This utilizes the high mechanical strength, excellent fatigue resistance, smooth surface, low coefficient of friction, and long service life of nylon filaments.

[0013] Preferably, the bottom of the inner folding plate is fixedly connected to an inclined guide plate, and the back of the vertical plate of the inner folding plate is provided with a groove on the side away from the first plate eave. A protruding prism is provided on the inner side of the groove and is fixedly connected to the inner folding plate. The bottom plate of the inner folding plate abuts against the outer wall of the suspension body through the inclined guide plate, increasing the contact area between the inner folding plate and the suspension body, making the inner folding plate more stable on the suspension body; avoiding the accumulation of heat inside the sweeping motor, and ensuring the safe operation of the sweeping motor.

[0014] Preferably, the rear end of the suspension body is equipped with a traveling rubber wheel, which is symmetrically arranged on the left and right sides of the suspension body. The traveling rubber wheel includes a second corner plate and is assembled with the suspension body by bolts. A second auxiliary support plate is installed on the side of the second corner plate near the first corner plate, and has the same structure as the first auxiliary support plate. The first and second auxiliary support plates are set at the same height and are used together to support the bottom track of the rigid contact network and support the suspension body to slide back and forth along the bottom track of the rigid contact network. Two movable slots are opened through the vertical plate of the second corner plate. An auxiliary rolling rubber wheel is rotatably installed on the second corner plate and is rotatably installed inside the movable slot by a long screw and nut. It can adjust the tightness of the contact between the auxiliary rolling rubber wheel and the side rail of the rigid contact network, thereby changing the smoothness of the traveling rubber wheel sliding on the rigid contact network. The auxiliary rolling rubber wheel and the active rubber wheel are set at the same horizontal plane, so that the main structural frame of the cleaning equipment has the advantages of light weight, easy processing and corrosion resistance, which facilitates the easy installation and disassembly of the cleaning equipment on the rigid contact network.

[0015] This invention provides a rotary cleaning device for rigid contact wire insulators in subways, which has the following advantages:

[0016] I. The rotary cleaning device for the rigid contact wire insulator of the subway increases the contact area between the inner folding plate and the air by opening grooves and setting convex prisms on the inner folding plate, thereby increasing the overall heat dissipation area of ​​the inner folding plate. This allows the heat generated by the cleaning motor during long-term operation to be dissipated in a timely manner, preventing heat accumulation inside the cleaning motor and ensuring the safe operation of the cleaning motor.

[0017] II. The rotary cleaning device for the rigid contact wire insulators of the subway, by starting the cleaning motor to drive the cleaning rod on the telescopic rod to rotate, can also drive the nylon wire on the cleaning rod to rotate up and down through the up and down extension and retraction of the telescopic rod. This allows for the up and down rotation cleaning of the insulators, and can also perform adaptive cleaning for insulators of different sizes and models, regardless of the size of the insulator.

[0018] Third, the rotary cleaning device for the rigid contact wire insulators of the subway, through the limiting installation of the cleaning motor by the buckle, can strengthen the installation stability of the cleaning motor between the inner folding plate and the first plate eave, ensure that the cleaning motor itself does not vibrate, and ensure that the cleaning motor can perform axial positioning and cleaning of the insulator surface around the cleaning rod, avoiding the phenomenon of scratching the insulator caused by the local misalignment of the cleaning rod, and ensuring the safety of the insulator.

[0019] Fourth, the rotating cleaning device for the rigid contact wire insulator of the subway provides the first layer of anti-sway protection for the fixed installation of the large plug rod inside the notch by blocking the large plug rod inside the notch with the convex strip; by fastening the hook plate inside the groove, it can provide the second layer of anti-sway interception protection for the fixed installation of the large plug rod inside the notch.

[0020] 5. The rotating cleaning device for the rigid contact wire insulator of the subway intercepts the large plug rod at the innermost side of the gap, so that the large plug rod has a certain resistance when it rotates into the gap, and it will also encounter a certain resistance when it comes out from the inside of the gap. This prevents the large plug rod from loosening inside the gap during use and ensures the smooth sliding of the auxiliary top rubber wheel in the bottom track of the rigid contact wire.

[0021] VI. The rotary cleaning device for the rigid contact wire insulator of the subway is installed inside the movable slot by a combination of long screws and nuts. It can adjust the tightness of the contact between the auxiliary rubber roller and the side rail of the rigid contact wire, thereby changing the smoothness of the sliding of the traveling rubber roller on the rigid contact wire. When there is a lot of dust accumulation on the side rail of the rigid contact wire, it can actively strengthen the tightness of the contact between the traveling rubber roller and the rigid contact wire to prevent derailment.

[0022] VII. The rotary cleaning device for the rigid contact wire insulators of the subway uses four auxiliary top rubber wheels that are sequentially pressed against the bottom rail. With the cooperation of the auxiliary top rubber wheels and the active rubber wheels, the front end of the cleaning device is slidably assembled with the rigid contact wire. With the cooperation of the second auxiliary support plate and the auxiliary rolling rubber wheel, the rear end of the cleaning device is slidably assembled with the rigid contact wire. This completes the overall assembly of the cleaning device on the rigid contact wire. Finally, the remote control module controls the drive rubber wheels to move the cleaning device back and forth on the rigid contact wire, while simultaneously performing up-and-down rotary self-cleaning of the insulators.

[0023] 8. This rotary cleaning equipment for the rigid contact network insulators of the subway changes the traditional operation method. It eliminates the need for high-altitude operations using ladder trucks and the requirement of at least six people to push the ladder truck, thus avoiding excessive personnel and waste. It also avoids the problem of manual cleaning efficiency gradually slowing down over time, as it can automatically rotate and clean the insulators up and down, solving the problem of dust and ash hazard to workers' health during traditional cleaning processes. At the same time, it avoids the safety hazards of objects and personnel falling from heights. It also standardizes the cleaning force and angle, resulting in a consistent level of cleanliness.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0034] First embodiment, such as Figures 1 to 8As shown, the present invention provides a technical solution: a rotary cleaning device for rigid contact wire insulators in subways, comprising a suspension body 1, a lithium battery 3 installed on the bottom front side of the suspension body 1 for providing power to a receiving module 8 and a cleaning motor 45, a receiving module 8 installed on the bottom rear side of the suspension body 1 for cooperating with a remote control module to control the operation of the drive wheel 2 and the cleaning component 4, a main beam plate 7 installed between the lithium battery 3 and the receiving module 8, and the top of the main beam plate 7 is assembled with the suspension body 1 by bolts, a square through slot is provided through the top center of the suspension body 1, and a hopper 6 is fitted inside the square through slot for collecting dust scattered by the cleaning component 4 when cleaning the surface of the insulator, and can be used to collect the dust scattered by the cleaning component 4 when cleaning the surface of the insulator after the cleaning work is completed. The bucket 6 is removed for unified cleaning of dust to prevent dust from accumulating directly on the lithium battery 3 over time, thus hindering its normal heat dissipation. It is then fitted onto the main beam plate 7 in the middle. A crossbeam plate 9 is installed through the front center of the suspension body 1. Seat plates 10 are bolted to the bottom of both ends of the crossbeam plate 9. The front end of the crossbeam plate 9 is combined with the lithium battery 3 via bolts and seat plates 10, while the rear end is combined with the receiving module 8 via bolts and seat plates 10. The receiving module 8 is electrically connected to a remote control module, enabling remote control of the cleaning component 4 to clean the insulators and control of the drive wheels 2 to move forward and backward on the rigid contact wire. This remote operation is convenient.

[0035] It also includes a drive rubber wheel 2, which is symmetrically installed on both sides of the front end of the suspension body 1. The drive rubber wheel 2 includes a first corner plate 21 installed on both sides of the suspension body 1 by bolts. A stepper motor 22 is fixedly installed on the vertical plate of the first corner plate 21. An active rubber wheel 23 is installed on the vertical plate of the first corner plate 21 and on the side facing away from the stepper motor 22. The active rubber wheel 23 is rotatably installed with the first corner plate 21 through the stepper motor 22.

[0036] The cleaning component 4 is installed on the top of the suspension body 1 and symmetrically installed on the middle of the left and right sides of the suspension body 1. The cleaning component 4 includes an inner folding plate 41. Hexagonal holes 411 are equally spaced on the bottom plate of the inner folding plate 41. Long screws 410 are threaded on the inner side of the hexagonal holes 411. The inner folding plate 41 is threaded to the suspension body 1 through the long screws 410. The top of the long screws 410 can be fitted into the bottom plate of the inner folding plate 41 through the hexagonal holes 411 to prevent the long screws 410 from obstructing the positioning and installation of the sweeping motor 45 on the inner folding plate 41. In addition, the long screws 410 can be used to dissipate heat from the bottom of the sweeping motor 45 downwards, thereby improving the heat conduction efficiency of the inner folding plate 41 and providing auxiliary heat dissipation.

[0037] The rear end of the suspension body 1 is equipped with a traveling rubber wheel 5, which is symmetrically arranged on the left and right sides of the suspension body 1. The traveling rubber wheel 5 includes a second corner plate 51 and is assembled with the suspension body 1 by bolts. A second auxiliary support plate 52 is installed on the side of the second corner plate 51 near the first corner plate 21, and has the same structure as the first auxiliary support plate 24. The first auxiliary support plate 24 and the second auxiliary support plate 52 are set at the same height and are used together to support the bottom track of the rigid contact network and support the suspension body 1 to slide back and forth along the bottom track of the rigid contact network. Two movable slots 53 are opened through the vertical plate of the second corner plate 51. An auxiliary rolling rubber wheel 54 is rotatably installed on the second corner plate 51 and is rotatably installed inside the movable slot 53 by long screws and nuts. The auxiliary rolling rubber wheel 54 and the active rubber wheel 23 are set on the same horizontal plane.

[0038] In use, after assembling the drive rubber wheel 2 onto the side rails on both sides of the rigid contact wire, the traveling rubber wheel 5 is also positioned and installed on the side rails on both sides of the rigid contact wire using the cooperation of long screws and nuts. Then, the swing plate 248 is rotated around the fixed pin 249, so that the large insertion rod 246 slides inside the limiting rail 2410 while ensuring that the large insertion rod 246 enters the innermost side through the notch 243. Then, the nut is tightened, and with the cooperation of the washer ring 247, the large insertion rod 246 is tightly assembled with the nylon thread 48, and the hook plate 242 is fastened inside the groove 244. At this time, the auxiliary top rubber wheel 2... 5. The four auxiliary top rubber rollers 25 are placed inside the bottom rail of the rigid contact network using the same operation as described above. With the cooperation of the auxiliary top rubber rollers 25 and the active rubber rollers 23, the front end of the cleaning equipment is slidably assembled with the rigid contact network. With the cooperation of the second auxiliary support plate 52 and the auxiliary rolling rubber rollers 54, the rear end of the cleaning equipment is slidably assembled with the rigid contact network. This completes the overall assembly of the cleaning equipment on the rigid contact network. Finally, the remote control module controls the drive rubber rollers 2 to drive the cleaning equipment to slide back and forth on the rigid contact network, while simultaneously performing up-and-down rotating self-cleaning of the insulators.

[0039] The auxiliary rubber roller 54 is rotated and installed inside the movable groove 53 by a long screw and nut. This allows for adjustment of the tightness of the contact between the auxiliary rubber roller 54 and the rigid contact wire side rail, thereby changing the smoothness of the sliding of the traveling rubber roller 5 on the rigid contact wire. When there is a lot of dust accumulation on the rigid contact wire side rail, the tightness of the contact between the traveling rubber roller 5 and the rigid contact wire can be actively strengthened to prevent derailment.

[0040] By using the walking rubber wheel 5 in conjunction with the driving rubber wheel 2, the cleaning equipment can move freely and suspend itself on the rigid contact wire. The cleaning component 4 can clean the top and bottom surfaces of the insulators, realizing the automatic rotation cleaning function of the cleaning equipment. The frame-like structural components in the suspension body 1, driving rubber wheel 2, cleaning component 4, walking rubber wheel 5, main beam plate 7, crossbeam plate 9, and seat plate 10 are all made of aluminum alloy, which makes the main structural frame of the cleaning equipment lightweight, easy to process, and corrosion resistant, facilitating easy installation and disassembly of the cleaning equipment on the rigid contact wire.

[0041] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 4 As shown, a first auxiliary support plate 24 is installed at the end of the first corner plate 21 near the lithium battery 3. An auxiliary top rubber wheel 25 is rotatably installed on the vertical plate of the first auxiliary support plate 24 and is located on the same plane as the active rubber wheel 23. A bottom-supporting folding plate 26 is installed at the end of the first auxiliary support plate 24 near the first corner plate 21 and is located at the front bottom of the suspension body 1. It is bolted to the bottom of the horizontal plate of the first corner plate 21 to enhance the installation strength of the bottom of the first corner plate 21 on the suspension body 1. At the same time, the side wall of the bottom-supporting folding plate 26 blocks the back-and-forth swaying of the small folding plate 241. It plays a role in strengthening the connection and support strength between the first corner plate 21 and the small folding plate 241.

[0042] The first auxiliary support plate 24 includes a small folded plate 241, which is bolted to the bottom of the front end of the suspension body 1. A hook plate 242 is hinged to the inclined side wall of the vertical plate of the small folded plate 241. A notch 243 and a groove 244 are provided on the inclined side of the vertical plate of the small folded plate 241. The groove 244 is located above the notch 243, and the hook plate 242 is hooked to the small folded plate 241 through the groove 244. Protrusions 245 are installed at equal intervals on the inner side wall of the notch 243. The large insert rod 246 is installed on the main body. A washer 247 is fixedly installed on the outer surface of the large insert rod 246. A swing plate 248 is installed on the side of the small folding plate 241 away from the auxiliary top rubber wheel 25. A limiting rail 2410 is opened through the surface of the swing plate 248. The large insert rod 246 passes through the limiting rail 2410 and is inserted into the swing plate 248. It is assembled with the swing plate 248 by the cooperation of the nut and the washer 247. The washer 247 is limited and installed between the vertical plate of the swing plate 248 and the small folding plate 241.

[0043] A fixed pin 249 is rotatably installed at the middle of the end of the swing plate 248 away from the pad ring 247. The end of the fixed pin 249 away from the swing plate 248 is inserted into the vertical plate of the small folding plate 241. The swing plate 248 is rotatably installed with the small folding plate 241 through the fixed pin 249. The initial installation position of the swing plate 248, which is equipped with the auxiliary top rubber wheel 25, is located on the side wall of the small folding plate 241 and away from the first corner plate 21. An assembly nail 2411 is inserted at the end of the auxiliary top rubber wheel 25 away from the small folding plate 241. The assembly nail 2411 passes through the auxiliary top rubber wheel 25 and is threadedly connected to the large insertion rod 246. The auxiliary top rubber wheel 25 is rotatably installed with the small folding plate 241 through the cooperation of the assembly nail 2411 and the large insertion rod 246. Through the connection and assembly relationship between the above structures, the drive rubber wheel 2 can be quickly assembled on the rigid contact wire, which provides convenience for assembling the cleaning equipment on the rigid contact wire.

[0044] In use, by intercepting the large insertion rod 246 at the innermost side of the notch 243, there is a certain resistance when the large insertion rod 246 rotates into the notch 243, and there is also a certain resistance when it comes out from the inside of the notch 243. This prevents the large insertion rod 246 from becoming loose inside the notch 243 during use and ensures that the auxiliary top rubber wheel 25 slides smoothly in the bottom track of the rigid contact wire.

[0045] The protrusion 245 blocks the large insertion rod 246 inside the notch 243, providing the first layer of anti-sway protection for the fixed installation of the large insertion rod 246 inside the notch 243; by fastening the hook plate 242 inside the groove 244, the second layer of anti-sway protection for the fixed installation of the large insertion rod 246 inside the notch 243 can be provided.

[0046] The third embodiment is based on embodiments one and two; please refer to [link / reference]. Figures 6 to 8 As shown, a first eaves 42 and a second eaves 43 are fixedly connected to the vertical plate of the inner folding plate 41. The first eaves 42 are located between the bottom plate of the inner folding plate 41 and the second eaves 43. Openings are provided in the middle of the arc-shaped sides of the first eaves 42 and the second eaves 43. A buckle 44 is fixedly connected to the vertical plate of the inner folding plate 41 and is located between the bottom plate of the inner folding plate 41 and the first eaves 42. A cleaning motor 45 is fitted inside the buckle 44. The output end of the cleaning motor 45 is inserted into the opening at the top of the first eaves 42.

[0047] The top of the first eaves 42 is equipped with a telescopic rod 46, and the bottom is connected to the output end of the sweeping motor 45. The non-telescopic end of the telescopic rod 46 is installed inside the second eaves 43 through an opening. The telescopic end of the telescopic rod 46 extends from the top through the opening on the second eaves 43. The telescopic end of the telescopic rod 46 is threadedly connected to a threaded rod 49. The outer surface of the threaded rod 49 is threadedly connected to a sweeping rod 47. Nylon filaments 48 are installed on the outer surface of the sweeping rod 47 and are tied to the sweeping rod 47 in layers.

[0048] The bottom of the inner fold plate 41 is fixedly connected to an inclined guide plate 412. The back of the vertical plate of the inner fold plate 41 is provided with a groove 413, which is located away from the side where the first plate eave 42 is located. A protruding prism 414 is provided on the inner side of the groove 413 and is fixedly connected to the inner fold plate 41. The bottom plate of the inner fold plate 41 abuts against the outer wall of the suspension body 1 through the inclined guide plate 412, which increases the contact area between the inner fold plate 41 and the suspension body 1, making the inner fold plate 41 more stable on the suspension body 1.

[0049] In use, the cleaning motor 45 is limited by the buckle 44, which can strengthen the stability of the cleaning motor 45 between the inner folding plate 41 and the first plate eave 42, ensure that the cleaning motor 45 does not vibrate, and ensure that the cleaning motor 45 can perform axial positioning and cleaning of the insulator surface around the cleaning rod 47. This avoids the phenomenon of scratching the insulator caused by the cleaning rod 47 being accidentally tilted in some areas, thus ensuring the safety of the insulator.

[0050] By starting the cleaning motor 45 and driving the cleaning rod 47 on the telescopic rod 46 to rotate, the up-and-down movement of the telescopic rod 46 can drive the nylon wire 48 on the cleaning rod 47 to rotate up and down. This allows for the up-and-down rotation cleaning of the insulator, and also enables adaptive cleaning for insulators of different sizes, regardless of the size of the insulator. By using nylon wire to clean the insulator, the high mechanical strength, excellent fatigue resistance, smooth surface, low coefficient of friction, and long service life of nylon wire are effectively utilized.

[0051] By creating grooves 413 and convex prisms 414 on the inner folding plate 41, the contact area between the inner folding plate 41 and the air is increased, and the overall heat dissipation area of ​​the inner folding plate 41 is increased. This allows the heat generated by the sweeping motor 45 during long-term operation to be dissipated in a timely manner, preventing the accumulation of heat inside the sweeping motor 45 and ensuring the safe operation of the sweeping motor 45.
