Abstract
Description
Technical Field
[0001] This invention belongs to the field of power equipment technology, and specifically relates to an automatic insulator cleaning device. Background Technology
[0002] As the core insulating component of transmission lines, insulators serve a dual purpose of insulation and mechanical support, and their insulation performance directly affects the safety and stability of the power grid operation. During long-term outdoor use, insulator surfaces easily accumulate dust, industrial dust, and other contaminants, which reduce the insulator's insulation strength. In rainy conditions, rainwater forms a continuous water film on the insulator's skirt surface. When this water film mixes with surface contaminants, it significantly increases conductivity, easily triggering rainwater flashover faults and causing line outages. Simultaneously, rainwater splashed by oblique rainfall or wind easily adheres to the sides of the insulator and into the skirt grooves, making it difficult to detach naturally and further exacerbating the risk.
[0003] In existing technologies, a common approach is to install fixed rain covers or movable rain shields above the insulators to physically block vertically falling rainwater and reduce the area of the rain shelter exposed to rain. However, this approach has significant limitations. It can only effectively handle direct rainfall and cannot remove residual rainwater adhering to the sides or water films formed by oblique rainfall, thus limiting the protection range. Furthermore, fixed or partially movable structures can easily interfere with the insulator cleaning device, requiring manual disassembly or adjustment of the rain shield components before cleaning operations. This cumbersome process severely impacts the efficiency of power maintenance. Summary of the Invention
[0004] This invention provides an automatic insulator cleaning device, which aims to improve the cleaning efficiency of insulator surfaces and the efficiency of power maintenance.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An automatic insulator cleaning device is provided, comprising a housing, a first drive assembly, a gear ring, and a cleaning assembly. The housing is fitted onto the insulator and connected to the tower. A rain shield is arranged around the top of the housing, forming a rain collection space with the rain shield and the top of the housing. Multiple first drive assemblies are provided, each annularly spaced on the housing. Each first drive assembly has a drainage channel communicating with the rain collection space and a power conversion part for converting the kinetic energy of rainwater in the drainage channel into mechanical energy. The gear ring is rotatably connected to the housing and is poweredly connected to each power conversion part. The cleaning assembly is connected to the gear ring and has multiple cleaning parts annularly arranged around the outside of the insulator. The cleaning assembly is used to clean the surface of each insulator through these cleaning parts.
[0006] In one possible implementation, the housing includes a first cylinder and a second cylinder. The first cylinder is fixedly connected to the tower, and a rain shield is provided on the top of the first cylinder. Each first drive assembly is connected to the first cylinder. The second cylinder is disposed inside the first cylinder and coaxially connected to the first cylinder, and the second cylinder is rotatably connected to a gear ring.
[0007] In some embodiments, the first drive assembly includes drain pipes, rotating components, and gear rings. Multiple drain pipes are provided, each disposed on the first cylinder and spaced apart circumferentially around the first cylinder. Each drain pipe has a drainage channel inside and an impeller is disposed within each drain pipe. Multiple rotating components are provided, each rotatably disposed at the bottom of a corresponding drain pipe and coaxially connected to a corresponding impeller. Each rotating component has a drain outlet. Multiple gear rings are provided, each gear ring fitted onto a corresponding rotating component and meshing with a gear ring. The gear rings and impellers together form a power conversion section.
[0008] For example, a filter screen is provided at the top of the drain pipe.
[0009] For example, the bottom of the gear ring is equipped with an annular rain shield.
[0010] In one possible implementation, the cleaning assembly includes rods and scrapers. Multiple rods are provided, each vertically mounted on a gear ring and spaced apart circumferentially along the gear ring. Multiple scrapers are provided, each corresponding to one of the rods, and each scraper has an arcuate portion adapted to the surface of the insulator.
[0011] In some embodiments, the inner wall of the gear ring is provided with multiple pawls. The second cylinder includes a mounting cylinder and a rotating cylinder. The mounting cylinder is connected to the first cylinder. The rotating cylinder is rotatably mounted on the mounting cylinder, and a ratchet ring is provided on the rotating cylinder. The rotating cylinder is rotatably connected to the gear ring, and each pawl engages with the ratchet ring.
[0012] For example, the automatic insulator cleaning device further includes a second drive assembly. The second drive assembly includes a wind turbine and a transmission structure. The wind turbine is coaxially arranged with the insulator and rotatably mounted on the first cylinder. The transmission structure is poweredly connected to the wind turbine and driven by the rotating cylinder.
[0013] For example, a rotating disk is installed at the bottom of the wind turbine. The transmission structure includes a first bevel gear ring, a rotating shaft, and a second bevel gear ring. The first bevel gear ring is mounted on the rotating disk. Multiple rotating shafts are provided, each rotatably mounted on a mounting cylinder, and the axis of each shaft is horizontal. Each rotating shaft has a bevel gear at both ends, and one of the bevel gears meshes with the first bevel gear ring. The second bevel gear ring is mounted on the rotating cylinder and meshes with the bevel gear at the other end of the rotating shaft.
[0014] In one possible implementation, the housing is provided with guide grooves that communicate with each drainage channel.
[0015] The beneficial effects of the automatic insulator cleaning device provided by this invention are as follows: Compared with the prior art, this invention forms a rain collection space by using a rain shield on the top of the shell and the shell itself. This not only blocks vertically falling rainwater, reducing the rain-soaked area of the insulator skirts, but also collects and diverts rainwater, overcoming the limitation of traditional rainproof structures that can only handle direct rainfall. Utilizing the drainage channel and power conversion unit of the first drive component, the kinetic energy of the collected rainwater is converted into mechanical energy, driving the gear ring to rotate without additional external energy, thereby operating the cleaning components. This achieves a combination of efficient utilization of rainwater resources and automatic cleaning. Multiple ring-shaped cleaning parts surrounding the outside of the insulator can perform all-around cleaning of the insulator surface, effectively removing residual rainwater and dirt from the sides and skirt grooves, reducing the risk of water film formation and rainwater flashover faults at the source. The overall structure is fitted onto the insulator and connected to the tower, allowing cleaning operations to be completed without additional disassembly. This avoids spatial interference with the cleaning device, significantly improving the convenience and efficiency of power maintenance. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0020] Please refer to the following: Figures 1 to 9The automatic cleaning device for insulators 60 provided by the present invention will now be described. The automatic cleaning device for insulators 60 includes a housing 10, a first drive assembly 20, a gear ring 30, and a cleaning assembly 40. The housing 10 is fitted onto the insulator 60 and connected to the tower. A rain shield 13 is arranged around the top of the housing 10, forming a rain collection space with the rain shield 13 and the top of the housing 10. Multiple first drive assemblies 20 are provided, each arranged annularly at intervals on the housing 10. Each first drive assembly 20 has a drainage channel communicating with the rain collection space and a power conversion part for converting the kinetic energy of rainwater in the drainage channel into mechanical energy. The gear ring 30 is rotatably connected to the housing 10 and is poweredly connected to each power conversion part. The cleaning assembly 40 is connected to the gear ring 30 and has multiple cleaning parts annularly arranged around the outside of the insulator 60. The cleaning assembly 40 is used to clean the surface of each insulator 60 through each cleaning part.
[0021] It should be noted that when it rains outdoors, the vertically falling rainwater is first blocked by the rain shield 13 at the top of the housing 10, preventing it from directly washing over the insulator 60 skirt. Simultaneously, the rainwater flows along the inner wall of the rain shield 13 into the rain collection space for storage and accumulation. As the amount of rainwater in the collection space gradually increases, it flows naturally downwards through the drainage channels of each of the first drive components 20, forming a stable flow of kinetic energy within the drainage channels. The flowing rainwater impacts the power conversion section of the first drive component 20, converting the kinetic energy of the rainwater into the rotational mechanical energy of the power conversion section. Each power conversion section operates synchronously and transmits rotational power to the gear ring 30. Driven by the power conversion section, the gear ring 30 rotates at a uniform speed relative to the housing 10, thereby driving the connected cleaning component 40 to rotate synchronously. During the rotation of the cleaning component 40, multiple ring-shaped cleaning parts move in a circular motion along the surface of the insulator 60, thoroughly cleaning the residual rainwater, dust, industrial dust and other dirt on the surface, sides and grooves of the insulator 60, ensuring that there is no water accumulation or dirt residue on the surface of the insulator 60.
[0022] Compared with existing technologies, the automatic cleaning device for insulators 60 provided by this invention forms a rain collection space by using the rain shield 13 at the top of the housing 10 and the housing 10 itself. This not only blocks vertically falling rainwater, reducing the rain-soaked area of the insulator 60's skirts, but also collects and diverts rainwater, overcoming the limitation of traditional rainproof structures that can only handle direct rainfall. Utilizing the drainage channel and power conversion unit of the first drive assembly 20, the kinetic energy of the collected rainwater is converted into mechanical energy, driving the gear ring 30 to rotate without additional external energy, thereby operating the cleaning assembly 40. This achieves a combination of efficient rainwater utilization and automatic cleaning. Multiple ring-shaped cleaning parts surrounding the outside of the insulator 60 can perform all-around cleaning of the insulator 60's surface, effectively removing residual rainwater and dirt from the sides and skirt grooves, reducing the risk of water film formation and rainwater flashover faults at the source. The overall structure is fitted onto the insulator 60 and connected to the tower, allowing cleaning operations to be completed without additional disassembly, significantly improving the convenience and efficiency of power maintenance.
[0023] Please see Figure 1 and Figure 3 The housing 10 includes a first cylindrical body 11 and a second cylindrical body 12. The first cylindrical body 11 is fixedly connected to the tower, and a rain shield 13 is provided on the top of the first cylindrical body 11. Each first drive assembly 20 is connected to the first cylindrical body 11. The second cylindrical body 12 is disposed inside the first cylindrical body 11 and is coaxially connected to the first cylindrical body 11. The second cylindrical body 12 is rotatably connected to the gear ring 30.
[0024] It should be noted that the first cylinder 11 is an annular columnar structure, and its outer wall is fixedly connected to the tower rod through connectors to achieve stable installation of the entire device. The top edge of the first cylinder 11 is fixedly connected to the rain shield 13, together forming a rain collection space. Multiple first drive components 20 are evenly distributed and fixed along the circumferential sidewall of the first cylinder 11 to ensure the installation stability of each drive component. The second cylinder 12 is also an annular structure, coaxially nested in the internal cavity of the first cylinder 11. Its outer wall is fixedly connected to the inner sidewall of the first cylinder 11 through brackets, flanges and other connectors to ensure that their axes coincide. The outer or inner sidewall of the second cylinder 12 is connected to the gear ring 30 through rotating parts such as bearings, so that the gear ring 30 can rotate flexibly around the axis of the second cylinder 12. The first cylinder 11 and the second cylinder 12 are arranged coaxially to form a double-layer cylinder structure. The two do not interfere with each other and together constitute the shell 10.
[0025] The first cylinder 11 serves as the fixed support for the device. Its fixed connection with the tower ensures that components such as the rain shield 13 and the first drive assembly 20 remain stable in the outdoor environment. It also provides reliable top support for the rain collection space, ensuring that rainwater is collected smoothly and flows into the drainage channel of the first drive assembly 20. The second cylinder 12 acts as the rotating carrier of the gear ring 30. When the power from the first drive assembly 20 is transmitted to the gear ring 30, it provides stable rotational support for the gear ring 30, reducing swaying or offset during rotation and ensuring that the gear ring 30 can drive the cleaning assembly 40 to precisely contact the surface of the insulator 60 for cleaning. The coaxial design of the double-layer cylinders ensures that the power transmitted by the first drive assembly 20 acts stably along the axial direction on the gear ring 30, avoiding offset losses during power transmission, ensuring uniform rotation speed of the cleaning assembly 40, and improving the cleaning effect.
[0026] Please see Figures 4 to 6 The first drive assembly 20 includes drain pipes 21, rotating components 22, and gear rings 23. Multiple drain pipes 21 are provided, each disposed on the first cylinder 11 and spaced apart circumferentially along the first cylinder 11. Each drain pipe 21 has a drainage channel inside and an impeller 24 is disposed inside each drain pipe 21. Multiple rotating components 22 are provided, each rotatably disposed at the bottom of a corresponding drain pipe 21 and coaxially connected to a corresponding impeller 24. Each rotating component 22 has a drain outlet. Multiple gear rings 23 are provided, each gear ring 23 is fitted onto a corresponding rotating component 22 and meshes with a gear ring 30. The gear rings 23 and the impellers 24 together form a power conversion section.
[0027] It should be noted that the drain pipe 21 is a tubular structure, evenly spaced along the circumference of the first cylinder 11 and fixed to its side wall. The top of the drain pipe 21 extends upward to the top of the first cylinder 11, communicating with the rainwater collection space, and its hollow interior forms a complete drainage channel. The impeller 24 is horizontally installed inside the drain pipe 21 in the middle or lower section via a rotating shaft 522, and can rotate freely around its own axis. The rotating component 22 is a columnar structure, correspondingly set directly below each drain pipe 21, and is rotatably connected to the bottom end face of the drain pipe 21 via a bearing. The top of the rotating component 22 is fixedly connected to the rotating shaft 522 of the impeller 24 inside the drain pipe 21, so that the two rotate coaxially and synchronously. The drain outlet is opened at the lower part or bottom of the side wall of the rotating component 22 to discharge the rainwater flowing through the drain pipe 21. The gear ring 23 is a ring gear structure, which is fixedly sleeved on the outer side of the middle part of the rotating part 22 with interference fit or key connection. The teeth of each gear ring 23 face the direction of the gear ring 30 and mesh precisely with the outer circumferential teeth of the gear ring 30 to ensure smooth power transmission. The impeller 24 and the gear ring 23 are linked through the rotating part 22 to form a power conversion part.
[0028] Rainwater collected in the rainwater collection space flows into the drainage channel from the top of the drainage pipe 21 circumferentially around the first cylinder 11, forming a stable downward water flow. As the water flows through the drainage pipe 21, it impacts the blades of the impeller 24, causing the impeller 24 to rotate around its own axis. The rotation of the impeller 24 drives the rotating component 22 below to rotate synchronously via a coaxially connected rotating shaft 522. The rotation of the rotating component 22 synchronously drives the gear ring 23 on its outer side to rotate. The gear ring 23 corresponding to each drainage pipe 21 meshes with the gear ring 30, collectively transmitting rotational power to the gear ring 30, driving the gear ring 30 to rotate smoothly around the second cylinder 12. The rainwater flowing through the impeller 24 continues to flow downwards and is discharged outside the device through the drain outlet on the rotating component 22, preventing rainwater from accumulating in the drainage pipe 21 or the rotating component 22, ensuring a continuous and stable water flow, and thus guaranteeing the continuity of power conversion.
[0029] The power conversion unit, consisting of impeller 24 and gear ring 23, has a simple and compact structure, efficiently converting the kinetic energy of rainwater flow into the rotational mechanical energy of gear ring 30. It exhibits low power transmission loss and improves energy utilization efficiency. Multiple drain pipes 21 are evenly distributed circumferentially along the first cylinder 11, working in conjunction with the corresponding impeller 24 and gear ring 23 to ensure a more balanced driving force on gear ring 30 and smoother rotation. This, in turn, guarantees uniform and stable cleaning action of cleaning component 40, improving cleaning effectiveness. The drain outlet on rotating component 22 allows for rapid drainage of rainwater, preventing water accumulation from corroding or hindering the impeller 24 and rotating component 22, extending the service life of the power conversion unit, and ensuring long-term stable operation of the device.
[0030] Please see Figure 4 A filter screen 211 is installed at the top of the drain pipe 21.
[0031] It should be noted that the filter screen 211 has a mesh structure, and its shape is adapted to the outline of the pipe opening at the top of the drain pipe 21. It is fixedly installed at the top opening of the drain pipe 21, which just covers the water inlet end of the drain pipe 21, forming the first protective barrier before rainwater flows into the drainage channel.
[0032] During rainfall, rainwater collected in the collection space flows towards the drain pipe 21, first contacting the filter screen 211. The rainwater then smoothly seeps through the mesh of the filter screen 211 into the drainage channel inside the drain pipe 21, maintaining normal water flow. Debris such as leaves, pebbles, and larger dust particles mixed in with the rainwater are intercepted on the outside by the mesh of the filter screen 211, preventing them from entering the drainage channel and thus avoiding impacting the impeller 24 or clogging the drainage channel. The intercepted debris can be dislodged by natural wind or subsequent rainfall, or easily cleaned during maintenance, without affecting the normal filtration function of the filter screen 211 or the rainwater collection efficiency.
[0033] The filter screen 211 effectively blocks debris in rainwater from entering the drainage channel, preventing debris from clogging the drain pipe 21 or jamming the impeller 24, ensuring unobstructed drainage and normal rotation of the impeller 24, and ensuring stable operation of the power conversion unit.
[0034] Please see Figure 4 The bottom of the gear ring 30 is provided with an annular rain cover 31.
[0035] It should be noted that the annular rain shield 31 has an annular arc-shaped structure, with its top fixedly connected to the bottom end face of the gear ring 30, and is arranged around the entire circumference of the gear ring 30 to form a closed annular protective structure. The guide surface of the rain shield is an outwardly inclined arc shape, with the inner side close to the insulator 60 and the outer side extending outward, ensuring that rainwater can flow smoothly to all directions along the guide surface and not converge towards the insulator 60.
[0036] Rainwater in the drainage channel flows downwards through the drain outlet and falls directly onto the inclined guide surface of the annular rain shield 31, where it is completely intercepted. This prevents the rainwater from being deflected by wind during its descent and splashing onto the surface of the insulator 60. The intercepted rainwater is evenly distributed in all directions along the inclined guide surface of the rain shield, dripping naturally down the outer edge of the rain shield to the ground, forming an orderly drainage path that does not interfere with the insulator 60 or cleaning operations.
[0037] The annular guide shield can precisely intercept rainwater discharged from the drainage channel, effectively preventing rainwater from splashing onto the surface of insulator 60 under wind force, and preventing the formation of a water film on the surface of insulator 60 due to additional rain, further reducing the risk of rainwater flashover faults. The inclined guide surface achieves orderly diversion of rainwater in all directions, keeping rainwater away from insulator 60 and the transmission parts of the device, ensuring the cleanliness and dryness of the insulator 60 surface, preventing rainwater from corroding the transmission components, and extending the service life of the device.
[0038] Please see Figure 5 The cleaning assembly 40 includes rods 41 and scrapers 42. Multiple rods 41 are provided, each vertically mounted on the gear ring 30 and spaced apart circumferentially along the gear ring 30. Multiple scrapers 42 are provided, each correspondingly mounted on a rod 41 and having an arc-shaped portion adapted to the surface of the insulator 60.
[0039] It should be noted that the rod 41 is a long, vertical structure, with multiple rods 41 evenly spaced along the circumference of the gear ring 30. The top of each rod 41 is fixedly connected to the bottom end face of the gear ring 30, and the bottom extends downwards to a position close to the bottom of the insulator 60, ensuring full-height cleaning coverage of the insulator 60. The scraper 42 is a sheet-like structure, with one or more scrapers 42 fixed to each rod 41 according to the number of insulators 60. The installation position of the scraper 42 corresponds one-to-one with the positions of the insulator 60's skirts, sides, and grooves. The inner side of the scraper 42 has an arc-shaped portion, the curvature of which perfectly matches the contour of the insulator 60 surface, ensuring a tight fit. The rods 41 and scrapers 42 together form a ring-shaped cleaning structure, surrounding the outside of the insulator 60, staggered vertically from the ring-shaped rain shield 31 to avoid spatial interference and to ensure the drainage path of rainwater.
[0040] When the gear ring 30 rotates under the drive of the first drive assembly 20, it synchronously drives each vertical rod 41 fixed thereto to perform a circular motion around the axis of the insulator 60. As the rod 41 moves, it drives the scraper 42 on it to rotate synchronously. The arc-shaped portion of the scraper 42, adapted to the surface of the insulator 60, slides tightly against the surface, sides, and inner walls of the grooves of the insulator 60. During rotation, the scraper 42, through physical scraping, thoroughly removes residual rainwater, dust, industrial dust, and other contaminants adhering to the surface of the insulator 60, while also breaking up any water film that may form, ensuring that the surface of the insulator 60 is clean and dry.
[0041] The arc-shaped part of the scraper 42 precisely matches the surface of the insulator 60, and together with multiple circumferentially distributed rods 41, it achieves thorough cleaning of the entire surface of the insulator 60 without any blind spots. It can clean areas that are difficult to reach with traditional structures, such as the skirt grooves, preventing water film formation at the source. The multiple rods 41 are evenly distributed along the gear ring 30, ensuring a balanced cleaning force distribution around the insulator 60. This avoids damage to the insulator 60 caused by incomplete cleaning or excessive friction, guaranteeing both cleaning effectiveness and the insulator 60's service life. The cleaning component 40 has a simple and reliable structure, directly connected to the gear ring 30, providing direct and lossless power transmission. It requires no additional drive components, does not increase the device's size or weight, and does not interfere with other components, ensuring smooth overall operation.
[0042] Please see Figure 3 and Figure 7 The inner wall of the gear ring 30 is provided with multiple pawls 32. The second cylinder 12 includes a mounting cylinder 121 and a rotating cylinder 122. The mounting cylinder 121 is connected to the first cylinder 11. The rotating cylinder 122 is rotatably mounted on the mounting cylinder 121, and a ratchet ring 14 is provided on the rotating cylinder 122. The rotating cylinder 122 is rotatably connected to the gear ring 30, and each pawl 32 engages with the ratchet ring 14.
[0043] It should be noted that the mounting cylinder 121 is an annular columnar structure, and its outer wall is fixedly connected to the inner wall of the first cylinder 11, achieving coaxial fixation between the second cylinder 12 and the first cylinder 11. The rotating cylinder 122 is sleeved on the outside of the mounting cylinder 121 and is rotatably connected to the mounting cylinder 121 through bearings, allowing it to rotate freely around the axis of the mounting cylinder 121. The ratchet ring 14 is an annular structure, fixedly sleeved on the outer wall of the rotating cylinder 122, and coaxially arranged with the rotating cylinder 122; the tooth profile of the ratchet ring 14 matches the tooth profile of each pawl 32, and each pawl 32 forms a one-way meshing engagement with the ratchet ring 14. The gear ring 30 is sleeved on the outside of the rotating cylinder 122, maintaining coaxiality with the rotating cylinder 122 and being able to rotate relative to it.
[0044] When the first drive assembly 20 drives the gear ring 30 to rotate in the forward direction, the pawl 32 on the inner side of the gear ring 30 and the ratchet ring 14 on the rotating drum 122 are in a separated or idling state, and the two do not interfere with each other. The gear ring 30 can rotate smoothly and independently, driving the cleaning assembly 40 to complete the cleaning action. If the rotating drum 122 shows a tendency to rotate in the reverse direction, the one-way meshing structure between the pawl 32 and the ratchet ring 14 will slip, and it will be unable to drive the gear ring 30 to move in the reverse direction, ensuring that the gear ring 30 always maintains a forward rotation trend and does not affect the cleaning effect.
[0045] The one-way meshing design of the pawl 32 and the ratchet ring 14 ensures that the first drive assembly 20 drives the gear ring 30 to rotate in the forward direction without interference, and the rotation is smooth and without resistance. It can adapt to complex outdoor environments and is not prone to jamming or failure due to vibration, wind and rain, etc., thus ensuring the continuity and stability of the sweeping action.
[0046] Please see Figure 8 and Figure 9 The automatic cleaning device for insulator 60 also includes a second drive assembly 50. The second drive assembly 50 includes a wind turbine 51 and a transmission structure 52. The wind turbine 51 is coaxially arranged with the insulator 60 and rotatably mounted on the first cylinder 11. The transmission structure 52 is poweredly connected to the wind turbine 51 and is drivenly connected to the rotating drum 122.
[0047] It should be noted that the wind turbine 51 has an annular blade structure, coaxially arranged with the insulator 60, and rotatably mounted on the top or upper part of the first cylinder 11. The blades are evenly distributed circumferentially, without obstructing the rain shield 13 and the rain collection space, thus avoiding affecting rainwater collection. The transmission structure 52 is a power transmission structure, with its input end fixedly connected to the central rotating shaft 522 of the wind turbine 51, and its output end fixedly or meshingly connected to the rotating cylinder 122. The entire structure is arranged in the space between the first cylinder 11 and the second cylinder 12, without spatial interference with components such as the first drive assembly 20, gear ring 30, and cleaning assembly 40.
[0048] In outdoor environments with rain and wind, rainwater adheres more easily to the insulator 60, while strong winds act on the blades of the wind turbine 51, driving it to rotate around the axis of the insulator 60, converting wind energy into mechanical energy. The rotational power of the wind turbine 51 is transmitted to the rotating drum 122 through the transmission structure 52, causing the drum 122 to rotate in the forward direction. When the drum 122 rotates in the forward direction, its outer ratchet ring 14 meshes with the inner pawl 32 of the gear ring 30, thereby driving the gear ring 30 to rotate synchronously in the forward direction, providing auxiliary driving force for the cleaning component 40. At this time, the first drive component 20 has already driven the gear ring 30 to rotate in the forward direction through the kinetic energy of rainwater. The superposition of the two forces significantly enhances the rotational torque and speed of the cleaning component 40, improving the cleaning effect on the surface of the insulator 60 for rainwater and dirt. When there is only rain and no wind, the first drive component 20 drives the gear ring 30 to rotate in the forward direction. The pawl 32 and the ratchet ring 14 do not interfere with each other, and the transmission structure 52 and the wind wheel 51 will not generate reverse resistance, ensuring that the cleaning component 40 cleans normally. When there is no rain but there is wind, the second drive component 50 can also drive the cleaning component 40 to run, continuously keeping the surface of the insulator 60 clean.
[0049] Specifically designed for complex weather scenarios with rain and wind, this system utilizes wind-assisted drive to precisely address the issue of rainwater adhesion in such conditions. The dual-power superposition significantly enhances cleaning effectiveness, thoroughly removing rainwater and dirt from the surface of insulator 60, further reducing the risk of rain-induced flashover failures. The rain and wind-powered dual-power collaborative design requires no additional external energy source, making it energy-efficient, environmentally friendly, and more adaptable. Regardless of rainfall intensity or wind conditions, it ensures stable operation of the cleaning component 40, avoiding the shortcomings of a single power source in complex weather conditions. The power transmission path is independent and highly coordinated, with power superimposed only in the forward direction, without reverse interference, ensuring smooth operation of the first drive component 20 when working alone and improving the overall reliability of the device. The compact and well-sealed structure means the wind turbine 51 and transmission components do not occupy additional space, do not affect the maintenance of existing insulator 60 cleaning devices, and prevent wind and rain from corroding the transmission components, extending the device's service life.
[0050] Please see Figure 9 A rotating disk 511 is provided at the bottom of the impeller 51. The transmission structure 52 includes a first bevel gear ring 521, a rotating shaft 522, and a second bevel gear ring 524. The first bevel gear ring 521 is mounted on the rotating disk 511. Multiple rotating shafts 522 are provided, each rotatably mounted on the mounting cylinder 121, and the axis of each rotating shaft 522 is horizontal. Each rotating shaft 522 has a bevel gear 523 at both ends, and one end of the bevel gear 523 meshes with the first bevel gear ring 521. The second bevel gear ring 524 is mounted on the rotating cylinder 122 and meshes with the bevel gear 523 at the other end of the rotating shaft 522.
[0051] It should be noted that the rotating disk 511 is an annular flat plate structure, horizontally fixed to the bottom of the wind turbine 51, and coaxially arranged with the wind turbine 51 and the insulator 60, rotating synchronously with the wind turbine 51; the first bevel gear ring 521 is an annular bevel gear 523 structure, fixedly sleeved on the inner side wall or lower surface of the rotating disk 511, with the tooth surface facing the downward rotating shaft 522. Multiple rotating shafts 522 are evenly spaced along the circumference of the mounting cylinder 121, and each rotating shaft 522 is horizontally mounted on the side wall of the mounting cylinder 121 through bearings, with its axis perpendicular to the axis of the insulator 60, ensuring that the rotating shaft 522 can rotate flexibly; each rotating shaft 522 has a bevel gear 523 fixedly fitted at both ends, with the tooth surfaces of the two bevel gears 523 facing opposite directions, and the bevel gear 523 at the end closer to the axis of the insulator 60 precisely meshing with the tooth surface of the first bevel gear ring 521. The second bevel gear ring 524 is a ring bevel gear 523 structure, which is fixedly sleeved on the upper outer side wall of the rotating cylinder 122. The tooth surface faces the outer rotating shaft 522 and meshes with the bevel gear 523 at the end of each rotating shaft 522 away from the axis of the insulator 60, forming a complete power transmission closed loop. The entire transmission structure 52 is located in the annular space between the first cylinder 11 and the second cylinder 12, and does not interfere with the first drive assembly 20, gear ring 30 and other components.
[0052] When there is wind outdoors, the airflow drives the wind turbine 51 to rotate around the axis of the insulator 60. The wind turbine 51 synchronously drives the rotating disk 511 at the bottom and the first bevel gear ring 521 to rotate coaxially, converting wind energy into rotational mechanical energy. When the first bevel gear ring 521 rotates, it drives the bevel gears 523 at one end of each shaft 522 to rotate through meshing. Due to the meshing characteristics of the bevel gears 523, the vertical rotational power is converted into horizontal rotational power, driving each shaft 522 to rotate synchronously. When each shaft 522 rotates, the bevel gear 523 at the other end meshes with the second bevel gear ring 524, again converting the horizontal rotational power into vertical rotational power, driving the second bevel gear ring 524 and the rotating cylinder 122 fixed to it to rotate in the forward direction. When the rotating drum 122 rotates in the forward direction, the gear ring 30 is driven to rotate synchronously through the meshing of the ratchet ring 14 and the inner pawl 32 of the gear ring 30. This superimposes the power of the first drive component 20, enhancing the rotational torque and speed of the cleaning component 40. When the first drive component 20 works alone, the forward rotation of the gear ring 30 does not affect the ratchet ring 14, the transmission structure 52, or the impeller 51, and there is no reverse resistance interference.
[0053] Please see Figure 2 and Figure 4 The housing 10 is provided with a guide groove 15 that communicates with each drainage channel.
[0054] It should be noted that the flow channel 15 is opened on the top of the first cylinder 11 of the shell 10, and extends continuously along the circumference of the first cylinder 11 or is distributed at intervals corresponding to each drainage channel, forming a ring or segmented flow channel structure.
[0055] During rainfall, rainwater falling vertically or splashing at an angle is intercepted by the rain shield 13 and flows into the rain collection space. Some dispersed rainwater or rainwater flowing along the top of the housing 10 will converge into the guide channel 15. Due to the inclined design of the guide channel 15, rainwater flows directionally along the channel towards the inlet of each drainage channel under the action of gravity, preventing rainwater from accumulating or flowing disorderly at the top of the housing 10. The guide channel 15 concentrates and guides the dispersed rainwater to each drainage channel, ensuring that each drainage channel receives sufficient water flow, thereby ensuring that the impeller 24 of the first drive assembly 20 can continuously obtain stable kinetic energy and maintain the continuity of power conversion.
