Description

Technical Field

[0001] This invention relates to the field of surge arrester technology, and specifically to a surge arrester with high protective performance. Background Technology

[0002] A surge arrester is an electrical device used to protect electrical equipment from high transient overvoltages and to limit the duration and amplitude of follow current. Surge arresters are usually connected between the power grid conductor and the ground wire, but sometimes they are also connected beside the windings of electrical equipment or between conductors. Surge arresters are sometimes also called overvoltage protectors or overvoltage limiters. There are many types of surge arresters, including metal oxide surge arresters, line-type metal oxide surge arresters, gapless line-type metal oxide surge arresters, fully insulated composite-jacketed metal oxide surge arresters, and detachable surge arresters. The main types of surge arresters include tubular surge arresters, valve-type surge arresters, and zinc oxide surge arresters. The main working principle of each type of surge arrester is different, but their essential function is the same: to protect communication cables and communication equipment from damage.

[0003] In existing technologies, surge arresters are exposed to high-altitude strong winds, high humidity, and corrosive environments for extended periods. Their surfaces are susceptible to continuous accumulation of pollutants from multiple sources, such as bird activity (pollution from droppings), atmospheric dust deposition, and industrial salt spray adhesion. This leads to the formation of a conductive contamination layer on the insulator surface. This contamination layer significantly reduces the insulation strength of the equipment, causing abnormal increases in leakage current, distortion of electric field distribution, and even inducing surface flashover accidents. It also accelerates the corrosion process of metal components, ultimately resulting in a decrease in the surge arrester's lightning protection function and a decline in system reliability. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a surge arrester with high protection performance to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0006] A surge arrester with high protective performance includes a surge arrester body, a rotating shell externally disposed on the surge arrester body, insulating sleeves fixedly sleeved on the external terminals of the surge arrester body, a rotating platform disposed on the bottom surface of the surge arrester body, and two rainproof plates fixedly installed on the inner circular wall of the rotating shell; a protective assembly disposed inside the rotating shell to ensure the protective effect of the surge arrester body, the protective assembly including: two connecting frames, both of which are disposed inside the rotating shell, flexible brushes disposed on the external surface of the connecting frames, stabilizing columns fixedly installed on the top surface of the connecting frames, and connecting columns fixedly installed on the bottom surface of the connecting frames. A stabilizing ring is provided on one side of the stabilizing column, and the stabilizing ring is fixedly sleeved to the top of the surge arrester body. A movable ring is fixedly installed on one side of the connecting column, and the movable ring and the stabilizing ring are respectively movably sleeved to the bottom and top of the surge arrester body. Several fan blades are fixedly installed on the outer circular wall of the rotating platform. A first bearing is fixedly sleeved on the outside of the surge arrester body, and the outer circular wall of the first bearing is fixedly sleeved to the movable ring. A storage assembly for rotating the connecting frame and the flexible brush is provided on the top surface of the rotating shell. An intermittent pausing assembly for cleaning the surge arrester body is provided on the outer circular wall of the rotating platform.

[0007] By adopting the above technical solution, and through the flexible brush, when the surge arrester body is working in a relatively harsh environment for a long time, since the surge arrester body is installed at a high altitude, when the wind blows at high altitude, the fan blades will be blown by the wind. The fan blades, affected by the wind, will drive the rotating platform to rotate. Subsequently, the rotating platform will drive the connecting column, rotating shell, stabilizing column and connecting frame to rotate. Since the flexible brush is in contact with the surface of the surge arrester body, when the connecting frame rotates, it will drive the flexible brush to move in a circle on the surface of the surge arrester body. This facilitates the removal of contaminants such as dust, salt stains and bird droppings from the surface of the surge arrester body, avoids the degradation of insulation performance or surface flashover, and ensures the surge arrester's lightning protection function. This reduces the accumulation of a large amount of dust, oil or salt spray and other pollutants on the surface of the surge arrester body during long-term high-altitude operation. Furthermore, the rotation of the fan blades can disturb the air around the surge arrester body and increase the air velocity.

[0008] Preferably, the storage component includes: two mounting blocks, both of which are disposed on the top surface of the rotating shell. Two movable holes are respectively formed on the top and bottom surfaces of the rotating shell. A connecting frame is movably sleeved with the movable holes. A pressing groove is formed on the top surface of the connecting frame. A rotating column is fixedly installed on the inner bottom surface of the pressing groove. A spiral groove is formed on the outer circular wall surface of the rotating column. A spring is disposed on the inner bottom surface of the pressing groove. The spring is movably sleeved with the rotating column. A compression sleeve is fixedly installed on the bottom surface of the mounting block. A resistance column is fixedly installed on the inner circular wall surface of the compression sleeve. The compression sleeve is movably sleeved with the pressing groove. The rotating column is movably sleeved with the inner surface of the compression sleeve. The resistance column is slidably connected with the spiral groove. A gravity cylinder is disposed on the bottom surface of the mounting block. A sponge column is fixedly installed inside the gravity cylinder. A water inlet is formed on the top surface of the mounting block. A connecting hole is formed on the top surface of the gravity cylinder.

[0009] By adopting the above technical solution, the initial state of the gravity cylinder, connecting frame, and flexible brush is in contact with the surface of the surge arrester body. When it rains, rainwater enters the gravity cylinder through the water inlet and rotating shell. After the rainwater is collected inside the gravity cylinder, the sponge column absorbs the rainwater. When the sponge column is full of water, the remaining rainwater accumulates inside the gravity cylinder. Subsequently, the sponge column becomes heavier and heavier, which affects the gravity cylinder's own weight. As a result, the gravity cylinder will fall due to gravity. Then, the gravity cylinder will drive the water inlet, extrusion sleeve, and resistance column to move downward. Then, the extrusion sleeve moves to the bottom of the downward pressing groove and compresses the spring. At this time, the resistance column will move along the inside of the spiral groove. After being pressed by the resistance column, the inner wall of the spiral groove will rotate. The rotating column will then drive the connecting frame and flexible brush to rotate into the rotating shell. Subsequently, the two connecting frames will rotate into the rotating shell in a direction that brings them closer to each other, thus facilitating the storage of the connecting frame and flexible brush and preventing rainwater from wetting the flexible brush.

[0010] Preferably, the intermittent stopping component includes: a plurality of support rods, all of which are fixedly installed on the outer circular wall of the rotating platform; a support ring is provided on the top surface of the rotating platform; a rotating ring is fixedly installed on the top surface of the support ring; the support rods are fixedly installed to the support ring; a plurality of teeth are fixedly installed on the top surface of the rotating ring; an installation sleeve is fixedly sleeved on the outer circular wall of the insulating sleeve; a second bearing is fixedly sleeved on the outer circular wall of the installation sleeve; the outer circular wall of the outer ring of the second bearing is fixedly sleeved with the interior of the rotating platform; a toothed ring is fixedly installed on the bottom surface of the movable ring; a fixed ring is provided between the movable ring and the support ring; the fixed ring is movably sleeved with the surge arrester body; a plurality of movable columns are fixedly installed on the outer circular wall of the fixed ring; gears are movably sleeved on the outer circular wall of the movable columns; and the gears mesh with the toothed ring and the teeth respectively.

[0011] By adopting the above technical solution, the rotating ring, when the fan blades are rotated by wind, will drive the rotating platform, support rod, and support ring to rotate. The rotation of the support ring will drive the rotating ring to rotate, and the teeth will follow the rotating ring to mesh with the gear, causing the gear to rotate. The gear will mesh and drive the gear ring to rotate. Then, the gear ring will drive the movable ring and connecting column to rotate, thus enabling the rotating shell and connecting frame to move in a circle along the outside of the arrester body. Since multiple teeth are spaced apart on the rotating ring, each time the teeth mesh and drive the gear to rotate one revolution, the gear will disengage from the teeth, thus stopping the rotation of the gear and gear ring. Subsequently, under the rotation of the rotating ring, the teeth will mesh with the gear again, thereby realizing the intermittent rotation of the connecting frame and the flexible brush. This avoids the flexible brush from prolonged contact and friction with the outer wall of the arrester body, which would cause accelerated wear of the surface materials such as metal, coating, and insulation layer, affecting its lightning protection performance. At the same time, wind-driven rotation cleaning can replace manual climbing and cleaning, thereby reducing the safety risks of high-altitude operations.

[0012] Preferably, the outer circular wall of the stabilizing ring is provided with a rotating groove, and the inner top and inner bottom surfaces of the rotating groove are respectively provided with limiting grooves. A sliding plate is fixedly installed on one side of the stabilizing column, and a sliding block is fixedly installed on the top and bottom surfaces of the sliding plate. The sliding plate is movably connected with the rotating groove, and the sliding block is movably connected with the limiting groove.

[0013] By adopting the above technical solution, and through the setting of the stabilizing column, when the toothed ring and the movable ring drive the rotating shell to rotate by driving the connecting column, the rotating shell will drive the stabilizing column to rotate. In turn, the stabilizing column will drive the sliding plate and the sliding block to perform circumferential motion inside the rotating groove and the limiting groove, respectively, thereby facilitating the rotation and limiting of the stabilizing column, while supporting the top of the rotating shell to make it rotate stably.

[0014] Preferably, a blocking mesh is fixedly sleeved on the inner circular wall of the water inlet, and several vent holes are opened on the bottom surface of the gravity cylinder.

[0015] By adopting the above technical solution, the blocking net can block flexible debris such as plastic bags and leaves floating in the air when rainwater enters the gravity cylinder through the inlet and connection holes. When the rain stops and the sun shines, the gravity cylinder is exposed to the sun without any shielding, and the water inside the gravity cylinder and sponge column will slowly evaporate. As a result, the weight of the gravity cylinder will decrease, and the gravity cylinder will lose the weight of the compression spring. The spring will then push the compression sleeve to move the resistance column upward. The movement of the resistance column along the spiral groove will cause the rotating column to rotate and drive the connecting frame and flexible brush to rotate and reset, making it easier for the flexible brush to re-contact the surface of the surge arrester body for cleaning.

[0016] Preferably, a limiting rod is fixedly installed on the bottom surface of the mounting block, and two guide frames are fixedly installed on the outer circular wall of the rotating shell, with the limiting rod slidably connected to the guide frames.

[0017] By adopting the above technical solution, the vertical movement of the mounting block and the gravity cylinder can be limited.

[0018] Preferably, a connecting ring is fixedly installed on the bottom surface of the mounting block, the outer circular wall of the connecting ring is threaded, the inner circular wall of the connecting hole is threaded, and the connecting ring is threadedly connected to the connecting hole.

[0019] By adopting the above technical solution, the gravity cylinder can be loosened by rotating it, and then removed from the outside of the connecting ring, making it easy to disassemble. Conversely, the gravity cylinder can be installed, making it easy for workers to replace. This prevents the sponge column from turning to powder and reducing its water absorption effect due to long-term use at high altitudes.

[0020] Preferably, the top and bottom surfaces of the connecting frame are respectively provided with threaded posts, and a cleaning frame is provided on the outside of the connecting frame. The cleaning frame is fixedly installed with the flexible brush, and the threaded posts pass through the cleaning frame and are threadedly connected to the connecting frame.

[0021] By adopting the above technical solution, the cleaning frame and flexible brush can be disassembled so that workers can clean or replace the flexible brush.

[0022] Preferably, the inner circular wall of the rotating shell is provided with a detection groove, a miniature infrared temperature sensor is fixedly installed on the inner circular wall of the detection groove, and a transparent block is fixedly sleeved on the inner circular wall of the detection groove.

[0023] By adopting the above technical solution, and by setting up a miniature infrared temperature sensor, the miniature infrared temperature sensor can emit infrared light to detect the temperature of the surge arrester body, which is convenient for detecting the external temperature of the surge arrester body, so as to detect aging or moisture problems of the surge arrester body in a timely manner.

[0024] Preferably, a mounting shell is fixedly installed on the outer circular wall of the rotating shell, a fixing groove is provided on one side of the mounting shell, a plurality of indicator lights are fixedly installed on one side of the fixing groove, and a transparent plate is fixedly installed inside the fixing groove.

[0025] By adopting the above technical solution and by setting up indicator lights, when the surge arrester body and rotating shell are installed at high altitude, the illumination of the indicator lights can help staff quickly locate the installation position of the surge arrester body at high altitude when maintaining the surge arrester body.

[0026] In summary, the present invention has the following main beneficial effects:

[0027] 1. This invention uses a flexible brush to adhere to the curved surface of the surge arrester body with a preset contact pressure, forming a closed-loop spiral trajectory motion under the drive of the connecting frame, and utilizes a continuous high-altitude wind field to achieve automatic operation without a power source, so as to remove contaminants such as dust, salt crystals, and bird droppings attached to the surge arrester body, reduce the corrosion of the surge arrester body caused by contaminants, and thus prevent the surge arrester body from weakening its lightning protection function.

[0028] 2. This invention reduces the probability of particulate matter adsorption by utilizing the airflow field generated by the rotation of the fan blades.

[0029] 3. This invention collects rainfall through a water inlet, a gravity cylinder, and a sponge column. It utilizes the capillary adsorption properties of the sponge material to achieve gradient accumulation of moisture. Furthermore, the spiral progressive retraction action of the flexible brush is achieved by driving the angular displacement of the rotating column.

[0030] 4. This invention utilizes a multi-stage power transmission system composed of a high-altitude wind-driven fan blade, a rotating platform, a support rod, a support ring, a rotating ring, teeth, gears, a gear ring, a movable ring, a connecting column, a rotating shell, a connecting frame, and a flexible brush. This system can achieve automated operation without external energy consumption by utilizing a continuous high-altitude wind field, thus avoiding the power supply and maintenance problems of traditional electric devices.

[0031] 5. The present invention uses a flexible brush 5 to fit the curved surface design, which makes it easy to adapt to the shape of surge arresters of different specifications;

[0032] 6. This invention uses multiple spaced teeth on a rotating ring to periodically mesh and disengage with the gear, forming a "meshing, indexing and disengaging" cycle. After each rotation of the gear, it disengages from the teeth, and the gear ring drives the connecting frame to complete a single cleaning action. After a single cleaning, the process is paused to avoid surface damage to the arrester body caused by prolonged continuous friction. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example: Reference Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 A surge arrester with high protective performance includes a surge arrester body 1, a rotating shell 2 externally disposed on the surge arrester body 1, an insulating sleeve 6 fixedly sleeved on the external terminal of the surge arrester body 1, a rotating platform 3 disposed on the bottom surface of the surge arrester body 1, two rain shields 24 fixedly installed on the inner circular wall of the rotating shell 2, and a protective component disposed inside the rotating shell 2 to ensure the protective effect of the surge arrester body 1. The protective component includes two connecting frames 4, both of which are disposed inside the rotating shell 2, and flexible brushes 5 disposed on the external surface of the connecting frames 4. A stabilizing column 7 is fixedly installed on the top surface of the connecting frame 4, and a connecting column 8 is fixedly installed on the bottom surface of the connecting frame 4. A stabilizing ring 9 is provided on one side of the stabilizing column 7. The stabilizing ring 9 is fixedly sleeved with the top of the surge arrester body 1. A movable ring 11 is fixedly installed on one side of the connecting column 8. The movable ring 11 and the stabilizing ring 9 are respectively movably sleeved with the bottom and top of the surge arrester body 1. Several fan blades 25 are fixedly installed on the outer circular wall of the rotating platform 3. A first bearing 10 is fixedly sleeved on the outside of the surge arrester body 1. The outer circular wall of the outer circle of the first bearing 10 is fixedly sleeved with the movable ring 11.

[0051] With the flexible brush 5 installed, when the surge arrester body 1 operates in a harsh environment for a long time, since the surge arrester body 1 is installed at a high altitude, the wind will blow the fan blade 25 when it gets windy. The fan blade 25 will drive the rotating platform 3 to rotate after being affected by the wind. Subsequently, the rotating platform 3 will drive the connecting column 8, rotating shell 2, stabilizing column 7 and connecting frame 4 to rotate. Since the flexible brush 5 is in contact with the surface of the surge arrester body 1, when the connecting frame 4 rotates, it will drive the flexible brush 5 to move in a circle on the surface of the surge arrester body 1. This facilitates the removal of contaminants such as dust, salt stains and bird droppings from the surface of the surge arrester body 1, avoids the degradation of insulation performance or surface flashover, and ensures the surge arrester's lightning protection function. This also reduces the accumulation of a large amount of dust, oil or salt spray and other pollutants on the surface of the surge arrester body 1 during long-term high-altitude operation. Furthermore, the rotation of the fan blade 25 can disturb the air around the surge arrester body 1 and increase the air velocity.

[0052] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The top surface of the rotating shell 2 is provided with a storage assembly for rotating the connecting frame 4 and the flexible brush 5. The storage assembly includes two mounting blocks 12, both of which are located on the top surface of the rotating shell 2. Two movable holes 13 are respectively opened on the top and bottom surfaces of the rotating shell 2. The connecting frame 4 is movably sleeved with the movable holes 13. A downward pressing groove 14 is opened on the top surface of the connecting frame 4. A rotating column 15 is fixedly installed on the inner bottom surface of the downward pressing groove 14. A spiral groove 16 is opened on the outer circular wall surface of the rotating column 15. A spring 17 is provided on the inner bottom surface of the downward pressing groove 14. The spring 17 is movably sleeved with the rotating column 15. The mounting blocks 1... A compression sleeve 18 is fixedly installed on the bottom surface of the mounting block 12. A resistance column 19 is fixedly installed on the inner circular wall of the compression sleeve 18. The compression sleeve 18 is movably connected to the lower pressure groove 14. The rotating column 15 is movably connected to the inside of the compression sleeve 18. The resistance column 19 is slidably connected to the spiral groove 16. A gravity cylinder 20 is provided on the bottom surface of the mounting block 12. A sponge column 23 is fixedly installed inside the gravity cylinder 20. A water inlet hole 21 is opened on the top surface of the mounting block 12. A connection hole 22 is opened on the top surface of the gravity cylinder 20. A blocking net 41 is fixedly sleeved on the inner circular wall of the water inlet hole 21. Several exhaust holes 42 are opened on the bottom surface of the gravity cylinder 20.

[0053] refer to Figure 7 and Figure 15 A limit rod 43 is fixedly installed on the bottom surface of the mounting block 12, and two guide frames 44 are fixedly installed on the outer circular wall of the rotating shell 2. The limit rod 43 is slidably connected to the guide frame 44.

[0054] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The gravity cylinder 20, connecting frame 4, and flexible brush 5 are initially in contact with the surface of the surge arrester body 1. When it rains, rainwater enters the gravity cylinder 20 through the water inlet 21 and rotating shell 2. After the rainwater is collected inside the gravity cylinder 20, the sponge column 23 absorbs the rainwater. When the sponge column 23 is full of water, the remaining rainwater accumulates inside the gravity cylinder 20. Subsequently, the sponge column 23 becomes increasingly heavy, affecting the gravity cylinder 20's own weight. As a result, the gravity cylinder 20 will fall due to gravity, and then the gravity cylinder 20 will... The moving water inlet 21, the extrusion sleeve 18 and the resistance column 19 move downward. Then the extrusion sleeve 18 moves to the bottom surface of the lower pressing groove 14 and compresses the spring 17. At this time, the resistance column 19 moves along the inside of the spiral groove 16. After the inner wall of the spiral groove 16 is pressed by the resistance column 19, the rotating column 15 will rotate. Then the rotating column 15 will drive the connecting frame 4 and the flexible brush 5 to rotate into the interior of the rotating shell 2. Subsequently, the two connecting frames 4 will rotate into the interior of the rotating shell 2 in a direction that brings them closer to each other, so as to facilitate the storage of the connecting frame 4 and the flexible brush 5 and prevent rainwater from wetting the flexible brush 5.

[0055] When the sun shines after the rain, the gravity cylinder 20 is exposed to the sun without any shielding. As a result, the moisture inside the gravity cylinder 20 and the sponge column 23 will slowly evaporate, and the weight of the gravity cylinder 20 will become lighter. Subsequently, the gravity cylinder 20 will lose the weight of the compression spring 17, and the spring 17 will push the compression sleeve 18 to move the resistance column 19 upward. The movement of the resistance column 19 along the spiral groove 16 will cause the rotating column 15 to rotate and drive the connecting frame 4 and the flexible brush 5 to rotate and reset, so that the flexible brush 5 can re-contact the surface of the surge arrester body 1 for cleaning.

[0056] refer to Figure 1 , Figure 2 , Figure 9 , Figure 10 and Figure 11The outer circular wall of the rotary table 3 is provided with an intermittent stopping assembly for cleaning and pausing the surge arrester body 1. The intermittent stopping assembly includes several support rods 26, all of which are fixedly installed on the outer circular wall of the rotary table 3. A support ring 30 is provided on the top surface of the rotary table 3, and a rotating ring 31 is fixedly installed on the top surface of the support ring 30. The support rods 26 are fixedly installed on the support ring 30. Several teeth 32 are fixedly installed on the top surface of the rotating ring 31. An installation sleeve 27 is fixedly sleeved on the outer circular wall of the insulating sleeve 6. The outer circular wall of sleeve 27 is fixedly sleeved with a second bearing 28. The outer circular wall of the outer ring of the second bearing 28 is fixedly sleeved with the inside of the rotating table 3. The bottom surface of the movable ring 11 is fixedly installed with a toothed ring 34. A fixed ring 33 is provided between the movable ring 11 and the support ring 30. The fixed ring 33 is movably sleeved with the lightning arrester body 1. Several movable columns 36 are fixedly installed on the outer circular wall of the fixed ring 33. Gears 35 are movably sleeved on the outer circular wall of the movable columns 36. The gears 35 are respectively meshed with the toothed ring 34 and the teeth 32.

[0057] refer to Figure 9 , Figure 10 and Figure 12 The outer circular wall of the stabilizing ring 9 is provided with a rotating groove 37. The inner top and inner bottom surfaces of the rotating groove 37 are respectively provided with limiting grooves 38. A sliding plate 39 is fixedly installed on one side of the stabilizing column 7. A sliding block 40 is fixedly installed on the top and bottom surfaces of the sliding plate 39. The sliding plate 39 is movably connected with the rotating groove 37, and the sliding block 40 is movably connected with the limiting groove 38.

[0058] refer to Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12Through the rotating ring 31, when the fan blade 25 rotates due to wind, the fan blade 25 will drive the rotating platform 3, support rod 26, and support ring 30 to rotate. The rotation of the support ring 30 will drive the rotating ring 31 to rotate, and the teeth 32 will mesh with the gear 35 as the rotating ring 31 rotates, causing the gear 35 to rotate. The rotation of the gear 35 will mesh with and drive the gear ring 34 to rotate. Then, the gear ring 34 will drive the movable ring 11 and the connecting column 8 to rotate, thereby causing the rotating shell 2 and the connecting frame 4 to move in a circle along the outside of the surge arrester body 1. Since multiple teeth 32 are spaced apart on the rotating ring 31, each time the teeth 32 mesh and drive the gear 35 to rotate one revolution, the gear 35 will disengage from the teeth 32, thereby stopping the rotation of the gear 35 and the gear ring 34. Subsequently, the rotating ring 31 will rotate in a circular motion. With the rotation of 1, the tooth 32 will mesh with the gear 35, thereby enabling the intermittent rotation of the connecting frame 4 and the flexible brush 5. This avoids the flexible brush 5 from being in prolonged contact and friction with the outer wall of the arrester body 1, which would cause accelerated wear of the surface materials such as metal, coating and insulation layer, affecting its lightning protection performance. At the same time, the wind-powered rotation cleaning can replace manual climbing and cleaning, thereby reducing the safety risks of high-altitude operations. When the toothed ring 34 and the movable ring 11 drive the connecting column 8 to rotate the rotating shell 2, the rotating shell 2 will drive the stabilizing column 7 to rotate. In turn, the stabilizing column 7 will drive the sliding plate 39 and the sliding block 40 to perform circumferential motion inside the rotating groove 37 and the limiting groove 38, respectively, thereby facilitating the rotational limiting of the stabilizing column 7 and supporting the top of the rotating shell 2 to make it rotate stably.

[0059] refer to Figure 3 , Figure 7 and Figure 8 A connecting ring 29 is fixedly installed on the bottom surface of the mounting block 12. The outer circular wall of the connecting ring 29 is threaded, and the inner circular wall of the connecting hole 22 is threaded. The connecting ring 29 is threadedly connected to the connecting hole 22. Threaded posts 46 are respectively provided on the top and bottom surfaces of the connecting frame 4. A cleaning frame 45 is provided on the outside of the connecting frame 4. The cleaning frame 45 is fixedly installed with the flexible brush 5. The threaded posts 46 pass through the cleaning frame 45 and are threadedly connected to the connecting frame 4.

[0060] By rotating the gravity cylinder 20, workers can loosen it and then remove it from the outside of the connecting ring 29, making it easy to disassemble. Conversely, the gravity cylinder 20 can be installed, making it easy for workers to replace. This prevents the sponge column 23 from becoming pulverized during long-term use at high altitudes, which would reduce its water absorption effect.

[0061] refer to Figure 1 , Figure 13 , Figure 14 and Figure 15The inner circular wall of the rotating shell 2 is provided with a detection groove 49. A miniature infrared temperature sensor 50 is fixedly installed on the inner circular wall of the detection groove 49. A transparent block 51 is fixedly sleeved on the inner circular wall of the detection groove 49. An installation shell 52 is fixedly installed on the outer circular wall of the rotating shell 2. A fixing groove 53 is provided on one side of the installation shell 52. Several indicator lights 47 are fixedly installed on one side of the inside of the fixing groove 53. A transparent plate 48 is fixedly installed inside the fixing groove 53.

[0062] The miniature infrared temperature sensor 50 can emit infrared light to detect the temperature of the surge arrester body 1, making it easy to detect the external temperature of the surge arrester body 1 and promptly identify aging or moisture problems. When the surge arrester body 1 and the rotating shell 2 are installed at high altitude, the light emitted by the indicator light 47 can help the staff quickly locate the installation position of the surge arrester body 1 at high altitude when maintaining the surge arrester body 1.

[0063] Working principle: Please refer to Figures 1-12 As shown, with the flexible brush 5, when the surge arrester body 1 is working in a harsh environment for a long time, since the surge arrester body 1 is installed at a high altitude, when the wind blows at high altitude, the fan blade 25 will be blown by the wind. The fan blade 25 will drive the rotating platform 3 to rotate after being affected by the wind. Subsequently, the rotating platform 3 will drive the connecting column 8, rotating shell 2, stabilizing column 7 and connecting frame 4 to rotate. Since the flexible brush 5 is in contact with the surface of the surge arrester body 1, when the connecting frame 4 rotates, it will drive the flexible brush 5 to move in a circle on the surface of the surge arrester body 1, which facilitates the removal of contaminants such as dust, salt stains and bird droppings from the surface of the surge arrester body 1, avoids the degradation of insulation performance or surface flashover, and ensures the surge protection function of the surge arrester. In order to reduce the accumulation of a large amount of dust, oil or salt spray and other pollutants on the surface of the surge arrester body 1 during long-term high-altitude operation, the rotation of the fan blade 25 can disturb the air around the surge arrester body 1 and increase the air velocity.

[0064] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The gravity cylinder 20, connecting frame 4, and flexible brush 5 are initially in contact with the surface of the surge arrester body 1. When it rains, rainwater enters the gravity cylinder 20 through the water inlet 21 and rotating shell 2. After the rainwater is collected inside the gravity cylinder 20, the sponge column 23 absorbs the rainwater. When the sponge column 23 is full of water, the remaining rainwater accumulates inside the gravity cylinder 20. Subsequently, the sponge column 23 becomes increasingly heavy, affecting the gravity cylinder 20's own weight. As a result, the gravity cylinder 20 will fall due to gravity, and then the gravity cylinder 20 will... The moving water inlet 21, the extrusion sleeve 18 and the resistance column 19 move downward. Then the extrusion sleeve 18 moves to the bottom surface of the lower pressing groove 14 and compresses the spring 17. At this time, the resistance column 19 moves along the inside of the spiral groove 16. After the inner wall of the spiral groove 16 is pressed by the resistance column 19, the rotating column 15 will rotate. Then the rotating column 15 will drive the connecting frame 4 and the flexible brush 5 to rotate into the interior of the rotating shell 2. Subsequently, the two connecting frames 4 will rotate into the interior of the rotating shell 2 in a direction that brings them closer to each other, so as to facilitate the storage of the connecting frame 4 and the flexible brush 5 and prevent rainwater from wetting the flexible brush 5.

[0065] When the sun shines after the rain, the gravity cylinder 20 is exposed to the sun without any shielding. As a result, the moisture inside the gravity cylinder 20 and the sponge column 23 will slowly evaporate, and the weight of the gravity cylinder 20 will become lighter. Subsequently, the gravity cylinder 20 will lose the weight of the compression spring 17, and the spring 17 will push the compression sleeve 18 to move the resistance column 19 upward. The movement of the resistance column 19 along the spiral groove 16 will cause the rotating column 15 to rotate and drive the connecting frame 4 and the flexible brush 5 to rotate and reset, so that the flexible brush 5 can re-contact the surface of the surge arrester body 1 for cleaning.

[0066] refer to Figure 1 , Figure 2 , Figure 9 , Figure 10 , Figure 11 and Figure 12Through the rotating ring 31, when the fan blade 25 rotates due to wind force, the fan blade 25 will drive the rotating platform 3, support rod 26, and support ring 30 to rotate. The rotation of the support ring 30 will drive the rotating ring 31 to rotate. Consequently, the teeth 32 will mesh with the gear 35 as the rotating ring 31 rotates, causing the gear 35 to rotate. The rotation of the gear 35 will mesh with and drive the gear ring 34 to rotate. Then, the gear ring 34 will drive the movable ring 11 and the connecting column 8 to rotate, thereby enabling the rotating shell 2 and the connecting frame 4 to move in a circular motion along the outside of the surge arrester body 1. Since multiple teeth 32 are spaced apart on the rotating ring 31 Each time the tooth 32 engages and drives the gear 35 to rotate once, the gear 35 will disengage from the tooth 32, thereby stopping the rotation of the gear 35 and the gear ring 34. Subsequently, under the rotation of the rotating ring 31, the tooth 32 will engage with the gear 35 again, thus enabling the intermittent rotation of the connecting frame 4 and the flexible brush 5. This avoids the flexible brush 5 from prolonged contact and friction with the outer wall of the surge arrester body 1, which would cause accelerated wear of the surface materials such as metal, coating and insulation layer, affecting its lightning protection performance. At the same time, wind-powered rotation cleaning can replace manual climbing cleaning, thereby reducing the safety risks of high-altitude operations.
