Description

Technical Field

[0001] This invention relates to the field of insulator cleaning technology, and more particularly to an insulator cleaning device. Background Technology

[0002] Insulators, as electrical devices capable of withstanding voltage and mechanical stress, are typically installed between conductors at different potentials or between a conductor and a grounding component. They are made of various materials, with ceramic insulators being a common type. While existing cleaning devices can accommodate insulators of different lengths and diameters, some ceramic insulators have overly complex shapes, such as "ceramic disc-shaped insulator strings." These insulators have grooves on one side and a smooth, convex shape on the other. When arranged in combination, the spatial gaps between them are complex. Traditional cleaning devices often have brushes positioned radially perpendicular to the ceramic insulator, making it difficult to adapt to these complex gaps. This results in poor cleaning effectiveness within the gaps, highlighting the shortcomings of existing technology. Summary of the Invention

[0003] The purpose of this invention is to provide an insulator cleaning device to solve the technical problem that the existing technology of using brushes to clean insulators is not effective.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An insulator cleaning device includes a main support cylinder and a secondary support cylinder, which are coaxially rotatably connected and both have open bottoms. The main support cylinder is equipped with a suspension mechanism, which includes a controller and a battery electrically connected to each other. The controller is equipped with a radio transmission module. A first electric push rod is radially fixed to the outer wall of the middle section of the secondary support cylinder, and a lifting frame is slidably connected to it. The lifting frame is fixed to the end of the push rod of the first electric push rod and also has a first servo motor fixed to it. The lifting frame has horizontal and coaxial spiral shafts rotatably connected to its front and rear sections along the front-rear direction. The shaft of the first servo motor is coaxially fixed to one of the spiral shafts. Both spiral shafts are jointly fixed to an inner transmission cylinder and slidably connected to an outer transmission cylinder along their common axial direction. The outer transmission cylinder has multiple rows of transmission blocks arranged axially and hinged at equal angles around its circumference. The swing direction of the transmission block is parallel to the axial direction of the outer transmission cylinder, and universal joints are installed on each of them. The input shaft of the universal joint is radially rotatably connected to the inner transmission cylinder, and the output shaft is interlocked with the universal joint. The output shaft of the universal joint can rotate circumferentially and slide axially along the transmission block, and a flexible brush roller is also fixed coaxially to the output shaft. A second servo motor, which is horizontally fixed in the front and back direction and electrically connected to the controller, is fixed at the front of the inner transmission cylinder. The shaft of the second servo motor is connected to the input shaft of the universal joint through a bevel gear. The main support cylinder and the auxiliary support cylinder are jointly equipped with an electric rotating mechanism. A conductive slip ring is installed at the front of the lifting frame. The stator of the conductive slip ring is electrically connected to the controller, and the rotor is electrically connected to the first and second servo motors. The outer transmission cylinder and the inner transmission cylinder are jointly equipped with an axial push-pull mechanism.

[0005] Based on the above technical solution, the axial push-pull mechanism includes a second electric push rod. The second electric push rod is fixed at the front of the lifting frame along the front-rear direction. A roller is rotatably connected to the rear end of the push rod of the second electric push rod. A horizontal tension spring is fixed at the rear end of the inner transmission cylinder. The rear end of the tension spring is fixed to the outer transmission cylinder. Under the elastic tension of the tension spring, the outer transmission cylinder tends to move forward relative to the inner transmission cylinder along the spindle. The roller rolls and rubs against the front end of the outer transmission cylinder. The second electric push rod is electrically connected to the controller.

[0006] Based on the above technical solution, a clamping mechanism is installed at both the front and rear parts of the main support cylinder. The clamping mechanism includes a third electric push rod and a gripper. The third electric push rod is fixed in a triangular arrangement along the circumferential direction at both the front and rear parts of the main support cylinder. Each of the third electric push rods is radial relative to the main support cylinder, and a gripper is fixed to the end of each push rod. Both the push rod and the gripper of the third electric push rod are made of insulating material. The centripetal part of each gripper is V-shaped. A serpentine tube is fixed at both the front and rear parts of the main support cylinder. A camera is fixed to the end of each of the two serpentine tubes. The camera and the third electric push rod are electrically connected to the controller.

[0007] Based on the above technical solution, the electric rotating mechanism includes a support frame, an external gear ring, a support plate, a third servo motor, gears, and photosensitive switches. The main support cylinder is disconnected in the middle, and the front and rear parts are jointly fixed with the support frame. The secondary support cylinder is rotatably connected to the disconnection in the middle of the main support cylinder. An incomplete external gear ring is coaxially fixed to the outer wall of the front part of the secondary support cylinder. Support plates are fixed to the outer walls of the left and right parts of the secondary support cylinder. Horizontal third servo motors are fixed to the rear ends of the two support plates. The third servo motors have a braking function. Gears are coaxially fixed to the shafts of the third servo motors. The external gear ring intermittently meshes with the two gears. The external gear ring is always meshed with at least one gear. Photosensitive switches are fixed to the left and right ends of the inner wall of the rear part of the secondary support cylinder. The two photosensitive switches correspond to the two third servo motors. When the secondary support cylinder rotates relative to the main support cylinder, the photosensitive switches can be intermittently blocked by the main support cylinder. The third servo motor and the photosensitive switches are electrically connected to the controller.

[0008] Based on the above technical solution, the support frame is hinged with connecting rods at both the front and rear ends, and connecting blocks are hinged to the upper parts of the two connecting rods respectively. A support base is installed on the top of the support frame. A No. 4 servo motor is fixed at both the front and rear ends of the support base, and the rotating shaft of the No. 4 servo motor is rotatably connected to the middle of the support base. The rotating shafts of the two No. 4 servo motors are respectively threaded through to the two connecting blocks. The top of the connecting block abuts against the bottom of the support base. The support base is equipped with multiple fastening components.

[0009] Based on the above technical solution, the fastening assembly includes a lower clamping plate, a stepped hole, a lower hexagonal bolt, a lower nut, a screw, an upper clamping plate, a V-groove, a filler block, and an upper nut. The top of the support base has multiple horizontal T-grooves along the left-right direction. The lower clamping plate is horizontally positioned with a vertical stepped hole running through its center. A lower hexagonal bolt is inserted into the stepped hole with a gap between its upper and lower parts. The head of the lower hexagonal bolt slides left-right with the T-groove. A lower nut is threaded onto the upper part of the lower hexagonal bolt and is placed inside the stepped hole. The top of the lower nut and the top of the lower hexagonal bolt are not higher than the top of the lower clamping plate. Vertical screws are fixed to the left and right sides of the top of the lower clamping plate. The upper clamping plate is horizontally positioned and is vertically inserted into the screws on the left and right sides of the lower clamping plate. A horizontal V-groove is formed in the center of the bottom of the upper clamping plate. A filler block is inserted into the V-groove, with its bottom flush with the bottom of the upper clamping plate. An upper nut is threaded onto the upper part of the screw and is pressed against the top of the upper clamping plate.

[0010] Compared with the prior art, the present invention has the following advantages: The present invention controls the electric rotating mechanism to rotate the auxiliary support cylinder, which enables the lifting frame and brush roller to move circumferentially relative to the insulator, thereby achieving circumferential coverage of the insulator. By controlling the first servo motor to rotate slowly, the inner and outer transmission cylinders can rotate slowly, thereby driving the brush roller to move circumferentially, performing slapping and cleaning on the surface of the insulator and its gaps. During this process, by controlling the second servo motor to rotate slowly, the input shaft of the universal joint can be rotated through the bevel gear, thereby causing the brush roller to rotate through the universal joint, thus performing rotational cleaning during the slapping and cleaning of the insulator, thereby improving the cleaning effect. By controlling the axial push-pull mechanism to move the outer and inner transmission cylinders axially, the angle between the brush roller and the insulator axis can be changed through the universal joint and transmission block, thereby better adapting to the grooves and smooth convexities of the ceramic disc-shaped porcelain insulator string, thereby achieving a good cleaning effect.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-7As shown, an insulator cleaning device includes a main support cylinder 1 and a secondary support cylinder 2, which are coaxially rotatably connected and have open bottoms. The main support cylinder 1 is equipped with a suspension mechanism, which includes a controller 4 and a battery 5 electrically connected to each other. The controller 4 is a known prior art technology, such as a microcontroller, and is equipped with a radio transmission module. A first electric push rod 6 is radially fixed to the outer wall of the middle part of the secondary support cylinder 2, and a lifting frame 7 is slidably connected to it. The lifting frame 7 is fixed to the end of the push rod of the first electric push rod 6 and is also fixed with a first servo motor 8. The front and rear parts of the lifting frame 7 are each rotatably connected to horizontal and coaxial spiral shafts 9 in the front-rear direction. The shaft of the first servo motor 8 is coaxially fixed to one of the spiral shafts 9. The two spiral shafts 9 are jointly fixed to an inner transmission cylinder 10 and are slidably connected to an outer transmission cylinder 11 in the same axial direction. The outer transmission cylinder 11 is circumferentially hinged with multiple rows of transmission blocks 12 arranged in the axial direction. The swing direction of the transmission block 12 is parallel to the axial direction of the outer transmission cylinder 11, and universal joints 13 are respectively installed on it. The input shaft of the universal joint 13 is radially rotatably connected to the inner transmission cylinder 10, and the output shaft is interlocked with the universal joint 13. The output shaft of the universal joint 13 can rotate circumferentially and slide axially along the transmission block 12, and a flexible brush roller 14 is also coaxially fixed to the output shaft. The front part of the inner transmission cylinder 10 is fixed with a horizontal part that is electrically connected to the controller 4 along the front-rear direction. The second servo motor 15 is connected to the main support cylinder 1 and the auxiliary support cylinder 2. The main support cylinder 1 and the auxiliary support cylinder 2 are equipped with an electric rotating mechanism. The front part of the lifting frame 7 is equipped with a conductive slip ring 17. The stator of the conductive slip ring 17 is electrically connected to the controller 4, and the rotor is electrically connected to the first servo motor 8 and the second servo motor 15. The outer transmission cylinder 11 and the inner transmission cylinder 10 are equipped with an axial push-pull mechanism.

[0021] In use, the controller 4 is controlled via radio signals. The cleaning device is mounted on the drone's landing gear using a suspension mechanism. The openings at the bottom of the main support cylinder 1 and the auxiliary support cylinder 2 allow them to be fitted onto the insulator. Controlling the electric rotation mechanism causes the auxiliary support cylinder 2 to rotate, enabling the lifting frame 7 and the brush roller 14 to move circumferentially relative to the insulator, thus achieving circumferential coverage. Controlling the first servo motor 8 to rotate slowly causes the inner transmission cylinder 10 and the outer transmission cylinder 11 to rotate slowly, thereby driving the brush roller 14 to move circumferentially, patting and cleaning the surface and gaps of the insulator. During this process, controlling the second servo motor 15 to rotate slowly causes the input shaft of the universal joint 13 to rotate via the bevel gear 31, thereby enabling the universal joint 13 to... The brush roller 14 rotates, thus rotating and cleaning the insulator during the beating and sweeping process, thereby improving the cleaning effect. By controlling the axial push-pull mechanism, the outer transmission cylinder 11 and the inner transmission cylinder 10 can move axially, thereby changing the angle between the brush roller 14 and the insulator axis through the universal joint 13 and the transmission block 12. This allows it to better adapt to the grooves and smooth protrusions of the ceramic disc-shaped porcelain insulator string, thereby achieving a good cleaning effect. By controlling the extension and retraction of the first electric push rod 6, the lifting frame 7 can move radially relative to the auxiliary support cylinder 2, thereby changing the radial position of the brush roller 14 relative to the porcelain insulator, thus adapting to insulators of different diameters. By controlling the movement of the drone, the axial position of the brush roller 14 relative to the insulator can be changed, thus adapting to longer insulators.

[0022] The axial push-pull mechanism includes a second electric push rod 19. The second electric push rod 19 is fixed at the front of the lifting frame 7 along the front-rear direction. The rear end of the push rod of the second electric push rod 19 is rotatably connected to a roller 20. The rear end of the inner transmission cylinder 10 is fixed with a horizontal tension spring 21. The rear end of the tension spring 21 is fixed to the outer transmission cylinder 11. Under the elastic tension of the tension spring 21, the outer transmission cylinder 11 tends to move forward relative to the inner transmission cylinder 10 along the flower shaft 9. The roller 20 rolls and rubs against the front end of the outer transmission cylinder 11. The second electric push rod 19 is electrically connected to the controller 4.

[0023] By controlling the extension and retraction of the second electric push rod 19, the front-to-back position of the outer transmission cylinder 11 relative to the inner transmission cylinder 10 can be changed under the elastic tension of the tension spring 21. Thus, under the traction of the universal joint 13 and the transmission of the transmission block 12, the angle of the brush roller 14 relative to the axial direction of the outer transmission cylinder 11 is changed, that is, the angle relative to the axial direction of the insulator is changed.

[0024] The main support cylinder 1 is equipped with clamping mechanisms at both the front and rear ends. Each clamping mechanism includes a third electric push rod 23 and a gripper 24. The main support cylinder 1 has three electric push rods 23 arranged in a triangular pattern at both the front and rear ends. Each of the three electric push rods 23 is radial relative to the main support cylinder 1, and a gripper 24 is fixed to the end of each push rod. Both the push rod and the gripper 24 of the three electric push rods 23 are made of insulating material. The centripetal part of each gripper 24 is V-shaped. The main support cylinder 1 is also equipped with a serpentine tube 25 at both the front and rear ends. A camera 26 is fixed to the end of each of the two serpentine tubes 25. The camera 26 and the three electric push rods 23 are electrically connected to the controller 4.

[0025] By controlling the extension of the No. 3 electric push rod 23, the grippers 24 can be aligned and brought closer together, thus clamping onto the support of the transmission line or the insulator shaft. This improves the coaxiality of the main support cylinder 1 and the auxiliary support cylinder 2 relative to the insulator, making it easier for the auxiliary support cylinder 2 to drive the brush roller 14 to clean the insulator in the circumferential direction. The camera can be used to conveniently observe the position and status of the insulator.

[0026] The electric rotating mechanism includes a support frame 27, an external gear ring 28, a support plate 29, a third servo motor 30, a gear 31, and a photosensitive switch 32. The main support cylinder 1 is disconnected in the middle, and the support frame 27 is fixed to both the front and rear parts. The auxiliary support cylinder 2 is rotatably connected to the disconnected part in the middle of the main support cylinder 1. An incomplete external gear ring 28 is coaxially fixed to the outer wall of the front part of the auxiliary support cylinder 2. Support plates 29 are fixed to the outer walls of the left and right parts of the auxiliary support cylinder 2. Horizontal third servo motors 30 are fixed to the rear ends of the two support plates 29 respectively. The third servo motor 30 has... The device has a braking function. The shafts of the three servo motors 30 are coaxially fixed with gears 31. The external gear ring 28 intermittently meshes with the two gears 31. The external gear ring 28 is always meshed with at least one gear 31. Photosensitive switches 32 are fixed at both ends of the inner rear wall of the auxiliary support cylinder 2. The two photosensitive switches 32 correspond to the two three servo motors 30. When the auxiliary support cylinder 2 rotates relative to the main support cylinder 1, the photosensitive switches 32 can be intermittently blocked by the main support cylinder 1. The three servo motors 30 and the photosensitive switches 32 are electrically connected to the controller 4.

[0027] Furthermore, by controlling the third servo motor 30 to rotate alternately, the engagement of gear 31 with the external gear ring 28 can cause the auxiliary support cylinder 2 to rotate relative to the main support cylinder 1. Specifically, since at least one photosensitive switch 32 is blocked by the main support cylinder 1, when both photosensitive switches 32 are blocked by the main support cylinder 1, one of the servo motors 30 starts to rotate. This causes the auxiliary support cylinder 2 to rotate relative to the main support cylinder 1 by meshing the gear 31 with the external gear ring 28. This state is called a1. When one photosensitive switch 32 is not blocked by the main support cylinder 1, the corresponding servo motors 30 before and after it stop rotating (non-braking). At this time, the position of the servo motor 30 corresponds to the bottom opening of the main support cylinder 1, while the other servo motor 30 is rotating. This facilitates the re-meshing of the gear 31 and the external gear ring 28 on the shaft of the stopped servo motor 30. This state is called a2. When the corresponding photosensitive switch 32 is blocked by the main support cylinder 1, if both photosensitive switches 32 are blocked, a1 is executed; if only one is blocked, a2 is executed, and so on. When it is necessary to remove the cleaning device from the insulator, once the opening of the main support cylinder 1 and the opening of the auxiliary support cylinder 2 are aligned, the two or three servo motors 30 can be braked.

[0028] The support frame 27 has connecting rods 33 hinged to its front and rear ends, and connecting blocks 34 are hinged to the upper parts of the two connecting rods 33 respectively. A support base 35 is installed on the top of the support frame 27. A fourth servo motor 36 parallel to the front and rear directions is fixed to the front and rear ends of the support base 35. The rotating shaft of the fourth servo motor 36 is rotatably connected to the middle of the support base 35. The rotating shafts of the two fourth servo motors 36 are respectively threaded through to the two connecting blocks 34. The top of the connecting block 34 abuts against the bottom of the support base 35. The support base 35 is equipped with multiple fastening components 37.

[0029] Furthermore, by fixing the fastening assembly 37 to the landing gear of the UAV and controlling the forward and reverse rotation of the fourth servo motor 36, the front and rear positions of the connecting block 34 relative to the support base 35 can be changed, thereby changing the axial angle between the main support cylinder 1 and the auxiliary support cylinder 2 relative to the landing gear. This adapts to insulators with different angles relative to the horizontal plane, thereby increasing the applicability and enhancing the cleaning effect.

[0030] The fastening assembly 37 includes a lower clamping plate 39, a stepped hole 391, a lower hexagonal bolt 40, a lower nut 41, a screw 42, an upper clamping plate 43, a V-groove 44, a filler block 45, and an upper nut 46. The support base 35 has multiple horizontal T-grooves 38 at its top end along the left-right direction. The lower clamping plate 39 is horizontally positioned and has a vertical stepped hole 391 running through its center. A lower hexagonal bolt 40 is inserted into the stepped hole 391 with a gap between its upper and lower ends. The head of the lower hexagonal bolt 40 slides horizontally with the T-groove 38. A lower nut 41 is threaded onto the upper part of the lower hexagonal bolt 40. The lower nut 41 and the lower hexagonal bolt 40 are placed inside the stepped hole 391. The top of the lower nut 41 and the top of the lower hexagonal bolt 40 are not higher than the top of the lower clamping plate 39. Vertical screws 42 are fixed on the left and right sides of the top of the lower clamping plate 39. The upper clamping plate 43 is horizontally set and is inserted into the screws 42 on the left and right sides of the lower clamping plate 39. A horizontal V-groove 44 is opened in the middle of the bottom end of the upper clamping plate 43. Filler blocks 45 are inserted into the V-groove 44. The bottom end of the filler blocks 45 is flush with the bottom end of the upper clamping plate 43. The upper nut 46 is threadedly connected to the upper part of the screw 42. The upper nut 46 is pressed against the top of the upper clamping plate 43.

[0031] Furthermore, the fastening assembly 37 can accommodate landing gears of different sizes and structural shapes. For long, flat landing gears, the upper clamping plate 43 and the lower clamping plate 39 are used to clamp the landing gear, and then the upper nut 46 is tightened. For round rod-shaped landing gears, the filler block 45 is removed, and then the V-groove 44 and the lower clamping plate 39 are used to clamp the landing gear, and then the upper nut 46 is tightened.

[0032] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
