Description

A UAV insulator curved arm cleaning device Technical Field

[0001] This application belongs to the technical field of insulator maintenance, and more specifically, relates to a cleaning device for the curved arm of an insulator on a drone. Background Technology

[0002] Currently, various types of insulators are widely used in power transmission networks, substations, and distribution networks. Insulators play a vital role in insulating lines from the ground, and their condition directly affects the normal operation of lines and equipment. Therefore, insulator maintenance is an important task for line maintenance workers.

[0003] Currently, the dust removal and cleaning of insulators is mostly done manually, which requires power outages on equipment or lines. Line maintenance personnel climb the poles one by one to clean the insulators on the towers with semi-dry cloths. Substation maintenance personnel need to shut down the entire station and manually climb ladders to clean the insulators on the equipment and incoming and outgoing lines. This method has high safety risks and low cleaning efficiency. Summary of the Invention

[0024] The present application provides a description of a cleaning device for the curved arm of an insulator for unmanned aerial vehicles.

[0025] As shown in Figures 1, 2 and 3, one embodiment of this application provides a cleaning device for the curved arm of an insulator of a drone, including a support arm 1, a rotating arm 2, a first rotating component 3, a control box 4, a cleaning head 5 and a telescopic assembly 6; the support arm 1 is used to connect to the drone, the rotating arm 2 is rotatably connected to one end of the support arm 1, and the first rotating component 3 is disposed inside the rotating arm 2 and is used to drive the rotating arm 2 to rotate.

[0026] The control box 4 is located at one end of the rotating arm 2, and the cleaning head 5 is located on the control box 4. The end of the cleaning head 5 facing away from the control box 4 has an opening for the insulator to pass through. The telescopic component 6 is located on the control box 4 and is used to drive the cleaning head 5 to move back and forth along the direction of the insulator passing through the opening.

[0027] This embodiment provides a drone-based insulator curved arm cleaning device. Compared with existing technologies, when cleaning insulators, the support arm 1 is installed on the drone, and the drone drives the device to the insulator, allowing the insulator to pass through the opening of the cleaning head 5. The first rotating arm 2 drives the rotating arm 2 to rotate, and the telescopic component 6 drives the cleaning head 5 to move, enabling the cleaning head 5 to clean the insulator from multiple angles. This effectively removes dust, stains, and other impurities from the surface of the insulator, improves the insulation performance of the insulator, and ensures the normal operation of lines and equipment. Compared with traditional manual cleaning methods, this device not only eliminates the need for power outages, improving cleaning efficiency, but also reduces safety risks during manual cleaning.

[0028] As shown in Figures 2 and 3, this application provides a specific embodiment based on the above embodiments as follows: The cleaning head 5 includes a fixed finger 51, a movable finger 52, and a cleaning cloth cover 53. The fixed finger 51 is connected to the telescopic component 6 in the middle. Multiple movable fingers 52 are arranged at both ends of the fixed finger 51. The inner sides between the fixed finger 51 and the movable finger 52, and the inner sides between adjacent movable fingers 52 are hinged. An opening is formed between two movable fingers 52 that are away from the fixed finger 51.

[0029] A cleaning cloth cover 53 is wrapped around the fixed finger 51 and all the movable fingers 52; an adjustment mechanism 7 is provided inside the fixed finger 51, which is used to drive all the movable fingers 52 to retract inward or expand outward at the same time to adjust the size of the opening.

[0030] The hinged structure allows the movable finger 52 to move flexibly via the adjustment mechanism 7, adaptively adjusting the opening size according to the size and shape of the insulator, thereby better enveloping the insulator and improving the fit and effectiveness of cleaning. The cleaning cloth 53 can absorb dust and stains on the surface of the insulator, wiping and cleaning the insulator during the movement of the cleaning head 5.

[0031] In practical applications, there is no need to equip insulators of different sizes with different cleaning heads, which reduces the cost of use and the complexity of equipment management.

[0032] As shown in Figures 3 to 5, this application provides a specific embodiment based on the above embodiments as follows: The adjustment mechanism 7 includes two main connecting ropes 71, multiple connecting branch ropes 72, and a set of drive components 73. Each fixed finger 51 and each movable finger 52 has a cavity to accommodate the main connecting rope 71. One end of the main connecting rope 71 is located in the movable finger 52, and the other end is located in the movable finger 52 furthest away. The connecting branch ropes 72 are connected to the main connecting ropes 71 at positions close to the hinge axes of each movable finger 52, and the end of the connecting branch rope 72 away from the main connecting rope 71 is fixed to the hinge axis of the movable finger 52.

[0033] The drive assembly 73 is located inside the fixed finger 51 and is used to simultaneously drive the two connecting main ropes 71 to retract, thereby driving all movable fingers 52 to expand outward; each movable finger 52 is also provided with a reset member on its hinge shaft. When the drive assembly 73 drives the connecting main rope 71 to release the rope, the reset member drives the corresponding movable finger 52 to retract to its initial position.

[0034] Specifically, in this embodiment, the reset component can be a torsion spring, which is sleeved on the hinge shaft and connected to two adjacent movable fingers 52, or connected to the movable finger 52 and the fixed finger 51.

[0035] When cleaning larger insulators, the drive assembly 73 causes the connecting main rope 71 to retract, and the movable finger 52 to expand outward, increasing the opening size so that the insulator can smoothly enter the cleaning head 5. The reset component ensures that the movable finger 52 can automatically return to its initial state after the cleaning operation is completed, preparing for the next cleaning work. This not only improves the ease of use of the device but also reduces manual intervention and improves work efficiency.

[0036] As shown in Figure 4, this application provides a specific implementation method based on the above implementation method as follows: The adjustment mechanism 7 further includes multiple guide shafts 74, each guide shaft 74 corresponding to a connecting branch rope 72. The guide shaft 74 is rotatably mounted on each movable finger 52 and located at the connection position between the corresponding connecting branch rope 72 and the connecting main rope 71. The guide shaft 74 is used to guide and support the pulling of the connecting branch rope 72.

[0037] During the process of the drive assembly 73 retracting or releasing the main connecting rope 71, the connecting branch rope 72 will undergo a pulling motion. The presence of the guide shaft 74 can guide the pulling of the connecting branch rope 72, making its movement smoother and more stable; it reduces the friction and wear between the connecting branch rope 72 and the movable finger 52, and extends the service life of the connecting branch rope 72.

[0038] Meanwhile, the stable pulling motion ensures that the adjustment mechanism 7 can control the movable finger 52 more precisely, allowing the movable finger 52 to accurately retract or expand, thereby better adjusting the opening size of the cleaning head 5, further improving the adaptability of the cleaning head 5 to insulators of different sizes, and enhancing the cleaning effect and the reliability of the device.

[0039] As shown in Figure 5, this application provides a further specific embodiment based on the above-described embodiments as follows: The drive assembly 73 includes a drive motor 731, a connecting shaft 732, and two rotating disks 733. The drive motor 731 is located in the middle of the fixed finger 51, and the connecting shaft 732 is rotatably mounted within the fixed finger 51. The drive motor 731 drives the connecting shaft 732 to rotate. The two rotating disks 733 are coaxially fixed on the connecting shaft 732, and the ends of the connecting main ropes 71 are fixed to the rotating disks 733 one-to-one. The two connecting main ropes 71 are wound in the same direction on the corresponding rotating disks 733.

[0040] Specifically, in this embodiment, the output shaft of the drive motor 731 and the connecting shaft 732 are perpendicular to each other. The fixed finger 51 is provided with a reversing transmission component connected between the output shaft of the drive motor 731 and the connecting shaft 732. The reversing transmission component can be two meshing bevel gears, one of which is coaxially fixed to the output shaft of the drive motor 731, and the other is coaxially fixed to the connecting shaft 732.

[0041] The drive motor 731 can drive the rotating disk 733 to rotate through the connecting shaft 732, thereby realizing the contraction and release of the connecting main rope 71; making the inward and outward movement of the movable finger 52 more precise, and able to accurately adjust the opening size of the cleaning head 5 according to the actual size of the insulator and the cleaning requirements.

[0042] In addition, the drive motor 731 is located in the middle of the fixed finger 51, which makes the structure of the drive assembly 73 more compact, reduces the space occupied by the device, and improves the overall layout rationality of the device.

[0043] As shown in Figure 6, based on the above embodiments, this application provides a specific embodiment as follows: The rotating arm 2 includes a rotating upper arm 21 and a rotating lower arm 22, which are coaxially rotatably connected. The rotating lower arm 22 is rotatably connected to the support arm 1. The control box 4 is installed at the end of the rotating upper arm 21, and the rotation axis of the rotating upper arm 21 is perpendicular to the rotation axis of the rotating lower arm 22 and the support arm 1. A second rotating component 8 for driving its rotation is provided inside the rotating upper arm 21.

[0044] Through the action of the second rotating component 8, the upper rotating arm 21 can rotate around its own axis; combined with the rotation of the lower rotating arm 22 and the support arm 1, as well as the rotation between the upper rotating arm 21 and the lower rotating arm 22, the cleaning head 5 can achieve multi-angle and all-round adjustment in three-dimensional space.

[0045] In actual cleaning work, for insulators at different positions and angles, the cleaning head 5 can be accurately aligned with the insulators by rotating the arm 2, improving the accuracy and effectiveness of cleaning; the multi-angle adjustment capability greatly enhances the adaptability of the device, enabling it to cope with various complex insulator installation environments, further improving cleaning efficiency and quality.

[0046] As shown in Figure 6, based on the above embodiments, this application provides a specific embodiment as follows: The first rotating component 3 includes a first rotating motor 31 and a first bearing 32. The first rotating motor 31 is disposed inside the rotating lower arm 22. The output shaft of the first rotating motor 31 extends into the support arm 1 and is fixed thereto. The first bearing 32 is disposed inside the support arm 1 and is coaxially connected with the output shaft of the first rotating motor 31.

[0047] The precise control capability of the first rotary motor 31 allows for accurate adjustment of the rotation angle and speed of the lower rotating arm 22, enabling flexible adjustment of its position and direction according to the needs of cleaning operations. The first bearing 32 ensures stable rotation of the output shaft of the first rotary motor 31, reducing friction and vibration during rotation and improving the smoothness and reliability of the lower rotating arm 22's rotation.

[0048] As shown in Figure 6, based on the above embodiments, this application provides a specific embodiment as follows: The second rotating component 8 includes a second rotating motor 81 and a second bearing 82. The second rotating motor 81 is disposed inside the rotating upper arm 21, and the output shaft of the second rotating motor 81 extends into the rotating lower arm 22 and is fixed thereto. The second bearing 82 is disposed inside the rotating lower arm 22 and is coaxially connected to the output shaft of the second rotating motor 81.

[0049] The precise control capability of the second rotary motor 81 allows for accurate adjustment of the rotation angle and speed of the rotating upper arm 21, enabling flexible adjustment of its rotation position according to the needs of cleaning operations. The second bearing 82 ensures stable rotation of the output shaft of the second rotary motor 81, reducing friction and vibration during rotation and improving the smoothness and reliability of the rotation of the rotating upper arm 21.

[0050] Referring to Figure 3, optionally, in this embodiment, the telescopic component 6 can be a motor and a screw. The motor is installed inside the control box 4, and the screw is rotatably disposed inside the control box 4 and coaxially connected to the motor output shaft. The fixed finger 51 is slidably inserted into the control box 4 towards the position of the control box 4 and threadedly connected to the screw. By driving the screw to rotate through the motor, the fixed finger 51 can slide closer to or further away from the control box 4.

[0051] In some possible embodiments, the telescopic component 6 can also be an electric cylinder, which is installed in the control box 4. The fixed finger 51 is directly fixed to the telescopic rod of the electric cylinder, and the movement of the fixed finger 51 is directly driven by controlling the electric cylinder.

[0052] As shown in Figure 3, based on the above embodiments, this application provides a specific embodiment as follows: a battery 41, a control circuit 42 and a remote control antenna 43 are provided inside the control box 4. The battery 41 and the remote control antenna 43 are both connected to the control circuit 42, and one end of the remote control antenna 43 extends to the outside of the control box 4.

[0053] The control circuit 42 is connected to the first rotary motor 31, the second rotary motor 81, the drive motor 731, and the telescopic assembly 6 via wiring to the motors or electric cylinders.

[0054] Battery 41 provides power to the entire device, ensuring sufficient energy supply during operation and guaranteeing normal cleaning work. Control circuit 42, as the core control component, coordinates and controls the operation of various parts, such as the drive motor 731 and the movement of the telescopic component 6. The remote control antenna 43 allows operators to operate and control the device remotely. Operators can adjust parameters such as the position, opening size, and movement mode of the cleaning head 5 from a safe distance, improving operational convenience and safety.

[0055] As shown in Figures 1 and 2, this application provides a specific embodiment based on the above embodiments as follows: the cleaning cloth cover 53 has a zipper opening at one end near the control box 4, and a zipper for closing the zipper opening is provided.

[0056] Specifically, in this embodiment, the cleaning cloth cover 53 has cleaning nipples evenly distributed on its outer surface to improve the cleaning effect on the insulator.

[0057] During the cleaning process, the cleaning cloth cover 53 gradually absorbs a large amount of dust and stains, affecting the cleaning effect. When the cleaning cloth cover 53 needs to be replaced, the operator can easily remove the old cleaning cloth cover 53 by simply unzipping it, then install the new cleaning cloth cover 53, and finally zip it up. This convenient replacement method reduces the time and labor costs required for replacing the cleaning cloth cover 53, and improves the efficiency of the device.
