Description

Technical Field

[0001] This invention relates to the field of grounding wire technology for unmanned aerial vehicles (UAVs), and in particular to a grounding wire device. Background Technology

[0002] Currently, during the maintenance of high-voltage transmission lines, to ensure safety, it is necessary to disconnect the power and short-circuit the high-voltage line with the ground wire. This operation usually requires high-altitude workers to climb to the monitoring line end and connect the high-voltage line to the tower using thick wires. High-altitude work is inherently high-intensity, and it also requires workers to carry equipment. With the development of modern drone technology, wireless technology, and industrial control technology, it has become possible for drones to replace high-altitude workers in carrying equipment to install grounding wires. Currently, using drones to install grounding wires typically involves attaching a fixed anchor and then pulling the ground wire to the line using an insulated rope. However, this method has poor balance and is prone to tipping over during the grounding process. Furthermore, the device relies on rope operation to lock the conductor and ground wire, requiring manual operation at the grounding end, making it unusable on high towers. In addition, the ground wire is mostly secured by simple clamps, which can easily come loose. Summary of the Invention

[0003] The technical problem to be solved by this invention is that the balance of the drone when attaching the grounding wire is poor, it is easy to tip over during the process of attaching the grounding wire, and the locking of the wire and the grounding wire relies on the operation of the rope. The grounding end needs to be operated manually, which makes it unusable on high towers and there is a possibility that the grounding wire may come loose.

[0004] To address the aforementioned technical problems, this invention provides a grounding wire attachment device, comprising a drone, a connecting rod, a grounding mechanism, two unhooking mechanisms, and a wire end mechanism. The drone is detachably connected to the wire end mechanism via the connecting rod, and the wire end mechanism is detachably connected to the grounding mechanism. The wire end mechanism includes a first clamping assembly for holding the wire and a first control unit. The first clamping assembly is detachably connected to the connecting rod via one of the unhooking mechanisms, and the first control unit is electrically connected to the first clamping assembly and the unhooking mechanism. The grounding mechanism includes a second clamping assembly, a wire winding assembly, and a second control unit. The second clamping assembly is connected to the wire winding assembly, and the wire winding assembly is detachably connected to the first clamping assembly via the other unhooking mechanism.

[0005] Furthermore, the first clamping assembly includes a bracket, a clamping arm structure, and a first driving member. The unhooking mechanism, the clamping arm structure, the first driving member, and the first control unit are mounted on the bracket. The first driving member is connected to the clamping arm structure to drive the clamping arm structure to tighten or loosen.

[0006] Furthermore, the bracket includes a frame, a connector, and an extension rod. The first drive member and the unhooking mechanism are installed on the frame. A notch is formed at one end of the frame, and the connector is installed at the notch to form a hook end. The extension rod is disposed at the other end of the frame, and the two extension rods form an included angle. The first control unit is installed on one of the extension rods, and the other extension rod is detachably connected to the unhooking mechanism.

[0007] Furthermore, the clamping arm structure includes a first connecting rod, a second connecting rod, a third connecting rod, a first clamping arm, and a second clamping arm. The first driving member passes through the bracket and is connected to one end of the first connecting rod. The two ends of the second connecting rod are respectively connected to the other end of the first connecting rod and the first clamping arm. The two ends of the third connecting rod are respectively connected to the other end of the first connecting rod and the second clamping arm. The first clamping arm and the second clamping arm are rotatably connected to the bracket, and the second connecting rod and the third connecting rod are respectively located on both sides of the first connecting rod.

[0008] Furthermore, the second clamping assembly includes a base, a clamping structure, and a second driving member. The clamping structure, the second driving member, and the second control unit are mounted on the base. The second driving member is connected to the clamping structure to drive the clamping structure to tighten or loosen.

[0009] Furthermore, the clamping structure includes two clamping arms, two racks, and a gear. The two racks mesh with the gear, and the clamping arms are connected to the corresponding racks. One end of the second driving member is connected to the gear to drive the two clamping arms to move relative to each other or away from each other.

[0010] Furthermore, the winding assembly includes a winding reel, a guide bracket, a guide wheel, and a third driving component. The winding reel and the guide bracket are disposed on the base, the guide wheel and the third driving component are mounted on the guide bracket, the third driving component is connected to the guide wheel, and the guide bracket is disposed on one side of the winding reel.

[0011] Furthermore, the grounding mechanism also includes a clamping assembly mounted on the reel to clamp or loosen the reel.

[0012] Furthermore, the unhooking mechanism includes a first base, a fourth driving member, a top block, a first connecting seat, and a tensioning block. The first base is connected to the first clamping assembly or the winding assembly, the first connecting seat is connected to the connecting rod or the first clamping assembly, and the two tensioning blocks are respectively installed at both ends of the first connecting seat. The fourth driving member is installed on the first base and connected to the top block to drive the top block to move and cause the tensioning block to hook or unhook from the first base.

[0013] Furthermore, the unhooking mechanism includes a second base, a fifth driving component, a rotating shaft, a hooking shaft, a second connecting seat, and a hook. The second base is connected to the first clamping assembly or the winding assembly, the second connecting seat is connected to the connecting rod or the first clamping assembly, the hooking shaft is mounted on the second connecting seat, the rotating shaft is mounted on the second base, and the hook is sleeved around the rotating shaft.

[0014] Compared with the prior art, the grounding wire hanging device of this invention has the following advantages:

[0015] This invention, through a precise drone control system combined with the additional support provided by the linkage, enables the device to maintain a relatively stable attitude in the air, thereby reducing the risk of tipping over. Furthermore, the use of mechanical clamping components instead of ropes improves the reliability of the attachment process. Simultaneously, the first and second control units allow remote activation of the clamping components and disengagement actions, enabling most operations to be remotely controlled by ground station personnel, significantly reducing manpower requirements and improving work efficiency. Finally, the detachable connection method allows for operation entirely by drone without requiring personnel to climb. Attached Figure Description

[0023] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0024] like Figures 1 to 4 As shown, the present invention provides a grounding wire attachment device, including a drone 1, a connecting rod 2, a grounding mechanism 3, two unhooking mechanisms 4, and a wire end mechanism 5. The drone 1 is detachably connected to the wire end mechanism 5 via the connecting rod 2, and the wire end mechanism 5 is detachably connected to the grounding mechanism 3. The wire end mechanism 5 includes a first clamping assembly 51 for clamping the wire and a first control unit 52. The first clamping assembly 51 is detachably connected to the connecting rod 2 via an unhooking mechanism 4, and the first control unit 52 is electrically connected to the first clamping assembly 51 and the unhooking mechanism 4. The grounding mechanism 3 includes a second clamping assembly 31, a winding assembly 32, and a second control unit 33. The second clamping assembly 31 is connected to the winding assembly 32, and the winding assembly 32 is detachably connected to the first clamping assembly 51 via another unhooking mechanism 4. The second control unit 33 is electrically connected to the second clamping assembly 31, the winding assembly 32, and the other unhooking mechanism 4.

[0025] Based on the above structure, the drone 1 first arrives at the control tower. The drone 1 is then lowered and the grounding mechanism 3 is placed at the ground wire angle iron. The second clamping component 31 of the remote control is manually operated to clamp the ground wire. The remote control is then manually operated to release the unhooking mechanism 4, and the grounding mechanism 3 is disconnected from the drone 1. The remote control is then manually operated to quickly release the wire using the winding component 32. The drone 1 assists in releasing the wire, and at the same time, the drone 1 flies away to the ground wire end. The wire end mechanism 5, carried by the drone 1, reaches a position above the wire and descends. The operator manually controls the remote control to clamp the wire with the first clamping component 51 of the wire end mechanism 5. The operator then manually controls the remote control to release the hook mechanism 4 of the wire end mechanism 5, separating the device from the connecting rod 2, and the drone 1 returns to its home position. When the device is being recovered, the drone 1 is carried to the recovery position and reaches above the wire end mechanism 5. The operator controls the drone 1 to connect the recovery hook to the wire end mechanism 5. The operator then manually releases the first clamping component 51, causing the drone 1 to rise and separate from the wire. The drone 1 flies to the ground wire end, and the operator simultaneously controls the wire reeling. After reeling to a certain extent, the operator manually releases the second clamping component 31, causing the drone 1 to rise and connect the wire end and the ground wire end together via the wire before returning to its home position.

[0026] This embodiment utilizes a precise UAV 1 control system, combined with the additional support provided by the linkage 2, to maintain a relatively stable attitude in the air, thereby reducing the risk of tipping over. Furthermore, the use of mechanical clamping components instead of ropes improves the reliability of the attachment process. Simultaneously, the first control unit 52 and the second control unit 33 allow for remote activation of the clamping components and disengagement actions, enabling most operations to be remotely controlled by ground station personnel, significantly reducing manpower requirements and improving work efficiency. Finally, a detachable connection method is adopted, allowing all operations to be performed by the UAV 1 without requiring personnel to climb to a height.

[0027] like Figure 2 As shown, the first clamping assembly 51 includes a bracket 511, a clamping arm structure 512, and a first driving member 513. The bracket 511 is the basic structure of the clamping assembly, which provides an installation platform for fixing and supporting other components. In this embodiment, the unhooking mechanism 4, the clamping arm structure 512, the first driving member 513, and the first control unit 52 are mounted on the bracket 511. The first driving member 513 is connected to the clamping arm structure 512 to drive the clamping arm structure 512 to tighten or loosen.

[0028] Understandably, the first control unit 52 in this embodiment includes necessary electronic components such as circuit boards, sensors, and processors to receive instructions from the ground station or UAV 1 and control the working state of the first drive unit 513. The control unit also includes a feedback mechanism, such as a pressure sensor, to detect whether the clamping force reaches a preset value, thereby ensuring that the wire is not damaged due to excessive tightness or detached due to excessive looseness.

[0029] Once the UAV 1 reaches the designated location, the first control unit 52 receives a clamping command from the ground station. According to the command, the first control unit 52 activates the first drive component 513, which begins to operate, driving the clamping arm structure 512 to gradually close until it tightly grips the high-voltage wire. When the clamping force reaches a set threshold, the first control unit 52 stops the first drive component 513 from further operation to prevent over-clamping. After completing the task, the first control unit 52 receives another command and reverses the operation of the first drive component 513, causing the clamping arm structure 512 to release the wire, preparing for the next action or retrieval.

[0030] See also Figure 3 The bracket 511 includes a frame 5111, a connector 5112, and an extension rod 5113. A first drive member 513 and a release mechanism 4 are installed on the frame 5111. A notch is formed at one end of the frame 5111, and the connector 5112 is installed at the notch to form a hook end for hooking with the recovery hook when the UAV 1 is carried and recovered. The extension rod 5113 is set at the other end of the frame 5111, and the two extension rods 5113 form an included angle. A first control unit 52 is installed on one extension rod 5113, and the other extension rod 5113 is detachably connected to the release mechanism 4.

[0031] In this embodiment, when the UAV 1 carrying the first clamping assembly 51 arrives at the predetermined position, the first control unit 52 receives an instruction and activates the first driving member 513 to drive the clamping arm structure 512 to close, thereby firmly clamping the wire. Under the action of the first driving member 513, the clamping arm structure 512 tightly wraps around the wire, ensuring that the wire will not slip through with appropriate clamping force. After completing the task of attaching the grounding wire, the first control unit 52 sends an instruction to the unhooking mechanism 4 to separate the clamping assembly from the UAV 1 or other structures. When recovery is required, the UAV 1 flies above the clamping assembly and uses the recovery hook to hook onto the connector 5112 to achieve the recovery of the clamping assembly.

[0032] Furthermore, the clamping arm structure 512 includes a first connecting rod 5121, a second connecting rod 5122, a third connecting rod 5123, a first clamping arm 5124, and a second clamping arm 5125. A first driving member 513 passes through the bracket 511 and is connected to one end of the first connecting rod 5121. The two ends of the second connecting rod 5122 are respectively connected to the other end of the first connecting rod 5121 and the first clamping arm 5124. The two ends of the third connecting rod 5123 are respectively connected to the other end of the first connecting rod 5121 and the second clamping arm 5125. The first clamping arm 5124 and the second clamping arm 5125 are rotatably connected to the bracket 511, and the second connecting rod 5122 and the third connecting rod 5123 are respectively located on both sides of the first connecting rod 5121.

[0033] In this embodiment, when the first driving member 513 is not activated, the first connecting rod 5121 is stationary. At this time, the first clamping arm 5124 and the second clamping arm 5125 maintain a certain opening angle, ready to clamp the wire. When the first control unit 52 receives a clamping command, the first driving member 513 starts to work, generating movement by pushing and pulling the first connecting rod 5121. As the first connecting rod 5121 moves, the second connecting rod 5122 and the third connecting rod 5123 also move accordingly. Since the second connecting rod 5122 and the third connecting rod 5123 are respectively connected to the first clamping arm 5124 and the second clamping arm 5125, they will drive the two clamping arms to move synchronously. Specifically, when the first connecting rod 5121 is pushed by the driving member, the second connecting rod 5122 and the third connecting rod 5123 are forced to expand outward, and drive the first clamping arm and the second clamping arm 5125 to close inward, thereby clamping the wire. As the first driving member 513 continues to apply force, the closing force between the clamping arms continuously increases until the preset clamping force is reached. At this time, the first control unit 52 may monitor the clamping force through a built-in pressure sensor and stop the operation of the drive component when a suitable value is reached to prevent over-clamping and damage to the wire. When it is necessary to release the wire, the first drive component 513 works in reverse, pulling the first link 5121, causing the second link 5122 and the third link 5123 to retract, thereby opening the first clamping arm 5124 and the second clamping arm 5125 to release the wire. In this embodiment, through the precise control of the first drive component 513 and the link 2 mechanism, the clamping arm structure 512 can achieve reliable clamping of the wire.

[0034] like Figure 4 As shown, the second clamping assembly 31 includes a base 311, a clamping structure 312, and a second driving member. The clamping structure 312, the second driving member, and the second control unit 33 are mounted on the base 311. The second driving member is connected to the clamping structure 312 to drive the clamping structure 312 to tighten or loosen.

[0035] Understandably, the second control unit 33 in this embodiment includes necessary electronic components such as circuit boards, sensors, and processors to receive instructions from the ground station or UAV 1 and control the operating state of the second drive unit. The control unit may also include a feedback mechanism, such as a force sensor or displacement sensor, to ensure that the clamping force is moderate, neither too tight nor too loose.

[0036] When no command is received, the clamping structure 312 of the second clamping assembly 31 remains open, awaiting clamping of the ground wire. When clamping of the ground wire is required, the second control unit 33 receives a command from the ground station or UAV 1. Based on the received command, the second control unit 33 activates the second drive, which drives the clamping structure 312 to close. Under the action of the second drive, the clamping structure 312 gradually closes until it firmly clamps the ground wire. The control unit adjusts the clamping force based on sensor feedback to ensure proper clamping. Once the clamping force reaches a preset value, the second control unit 33 stops the action of the second drive, and the clamping process is complete. When it is necessary to release the ground wire, the second control unit 33 receives another command and controls the second drive to work in reverse, causing the clamping structure 312 to open, thereby releasing the ground wire. This embodiment ensures that the ground wire is clamped safely and reliably for effective grounding operations. Through remote control by the second control unit 33, clamping and releasing are automated, reducing manual intervention and improving work efficiency.

[0037] Furthermore, the clamping structure 312 includes two clamping arms 3121, two racks 3122, and a gear. The two racks 3122 mesh with the gear, and the clamping arms 3121 are connected to the corresponding racks 3122. One end of the second driving member is connected to the gear to drive the two clamping arms 3121 to move relative to each other or move away from each other. The second driving member can be a motor or other driving member.

[0038] Without a drive, the clamping arm 3121 remains in a naturally open state, ready to accept the insertion of the ground wire. When the second drive receives a clamping command, it begins to operate, rotating the gear. The direction of gear rotation determines whether the clamping arm 3121 opens or closes. The rotation of the gear drives the two racks 3122 meshing with it to move in opposite directions in a linear motion. If the gear rotates clockwise, the two racks 3122 will move closer together; conversely, they will move apart. Since the racks 3122 are connected to the clamping arm 3121, the linear motion of the racks 3122 will cause the clamping arm 3121 to close or open accordingly. When the gear rotates, the two clamping arms 3121 will move relative to each other or move away, thereby clamping or releasing the ground wire.

[0039] When the clamping arm 3121 is closed, it tightly clamps the ground wire. The second control unit 33 monitors the clamping force and stops the drive mechanism when it reaches an appropriate value. When it is necessary to release the ground wire, the second drive mechanism rotates the gear in the opposite direction, causing the rack 3122 to move outward, thereby opening the clamping arm 3121 and releasing the ground wire. In this embodiment, the clamping structure 312 can effectively clamp the ground wire, ensuring a reliable connection between the ground wire and the high-voltage transmission line, thus achieving safe grounding. Through the mechanical linkage of the gear and rack 3122, the opening and closing of the clamping arm 3121 can be controlled very precisely, ensuring a uniform distribution of clamping force.

[0040] It should be noted that the clamping structure 312 is used to place the grounding mechanism 3 in the center of the tower angle iron surface by the synchronous inward clamping force at both ends when the grounding mechanism 3 is placed on the tower angle iron surface, and to clamp the vertical angle iron surface of the central protrusion, thereby reducing the possibility of the grounding mechanism 3 falling off due to wind and airflow.

[0041] Furthermore, the winding assembly 32 includes a winding reel 321, a guide bracket 322, a guide wheel 323, and a third drive component 324. The winding reel 321 and the guide bracket 322 are mounted on the base 311. The guide wheel 323 and the third drive component 324 are mounted on the guide bracket 322. The guide wheel 323 guides the direction of the ground wire, ensuring that the ground wire smoothly enters or leaves the winding reel 321. The guide wheel 323 is typically designed with a V-shaped or U-shaped groove to better fix the wire and prevent the wire from slipping or misaligning during winding and unwinding. The third drive component 324 is connected to the guide wheel 323. The third drive component 324 can be an electric motor, a pneumatic motor, or a hydraulic motor, etc., responsible for providing power to drive the guide wheel 323 to rotate, thereby controlling the winding and unwinding of the wire. The guide bracket 322 is located on one side of the winding reel 321.

[0042] When no instructions are received, the cable reel assembly 32 is stationary, with the wire wound on the reel 321. When it is necessary to pull the wire from the ground to the high-voltage transmission line, the third drive unit 324 activates, driving the guide wheel 323 to rotate. The rotation of the guide wheel 323 pulls the wire, unwinding it from the reel 321, and, guided by the guide wheel 323, smoothly pulls it towards the high-voltage transmission line as the UAV 1 flies. During this process, the guide wheel 323 not only guides the direction of the wire but also helps control the wire tension, preventing the wire from tangling or knotting. When it is necessary to retract the wire, the third drive unit 324 rotates in the opposite direction, and the guide wheel 323 also rotates in the opposite direction. The reverse rotation of the guide wheel 323 rewinds the wire back onto the reel 321.

[0043] Understandably, the second control unit 33 can control the speed and direction of the third drive unit 324 to ensure the smoothness and controllability of the wire winding and unwinding. It can also monitor the tension of the wire through feedback mechanisms such as tension sensors, and adjust the working state of the third drive unit 324 when necessary to ensure that the wire is not damaged due to excessive tension.

[0044] Furthermore, the grounding mechanism 3 also includes a clamping assembly 34, which is mounted on the reel 321 to clamp or loosen the wire coil. When the conductor is wound onto the reel 321, the clamping assembly 34 is in close contact with the conductor. As the conductor is continuously wound, the clamping assembly 34 follows the winding layers of the conductor, always maintaining pressure on the conductor. When it is necessary to unwind or adjust the conductor, the pressure of the clamping assembly 34 can be temporarily reduced by a drive or adjustment mechanism, or the clamping assembly 34 can be completely released. As the pressure of the clamping assembly 34 decreases or loosens, the conductor can be freely unwound from the reel 321.

[0045] There is a copper ring at the bottom of the coil. When the clamping device is released, the coil can rotate freely with the copper ring. When the clamping device clamps the coil, the copper ring of the coil is also clamped and fits against the plane of the ground wire end, achieving good contact and conduction. In addition, a pressure sensor is also installed. When the pressure on the beam of the clamping device reaches the preset value, the drive motor of the clamping device stops working.

[0046] like Figure 5 As shown, the unhooking mechanism 4 has two structures, namely, the unhooking mechanism 4 includes a first unhooking structure 41 and a second unhooking structure 42. The first unhooking structure 41 includes a first base 411, a fourth driving member 412, a top block 413, a first connecting seat 414, and a tensioning block 415. The first base 411 is connected to the first clamping assembly 51 or the winding assembly 32. The first connecting seat 414 is connected to the connecting rod 2 or the first clamping assembly 51. The two tensioning blocks 415 are respectively installed at both ends of the first connecting seat 414. The fourth driving member 412 is installed on the first base 411 and connected to the top block 413 to drive the top block 413 to move and drive the tensioning block 415 to hook or unhook from the first base 411.

[0047] When no command is received, the tension block 415 remains hooked to the first base 411, and the entire unhooking mechanism 4 is securely connected to the first clamping assembly 51 or the winding assembly 32. When it is necessary to maintain the connection, the tension block 415, under the lifting action of the top block 413, tightly hooks to the corresponding structure on the first base 411. This hooking state is achieved through the mechanical structure between the tension block 415 and the first base 411, ensuring that they will not accidentally separate during operation. When separation is required, the fourth drive member 412 receives the unhooking command and begins to work, driving the top block 413 to move in a straight line. The movement of the top block 413 causes the tension block 415 to lose its supporting force, causing it to rotate and disengage from the hooking state with the first base 411. When the tension block 415 is completely disengaged, the connection between the first connecting seat 414 and the first base 411 is released, thereby achieving unhooking.

[0048] It should be noted that this embodiment also includes two first displacement sensors 416 and a first sensing plate 417. The two first displacement sensors 416 are spaced apart on the first base 411. Through the cooperation of the first sensing plate 417 and the first displacement sensors 416, when the top block 413 moves to the designated position, the driving opening and closing of the fourth driving member 412 is controlled.

[0049] like Figure 6 As shown, the second unhooking structure 42 includes a second base 421, a fifth driving member 422, a rotating shaft, a hook shaft, a second connecting seat 423, and a hook 424. The second base 421 is connected to the first clamping assembly 51 or the winding assembly 32. The second connecting seat 423 is connected to the connecting rod 2 or the first clamping assembly 51. The hook shaft is installed on the second connecting seat 423. The rotating shaft is installed on the second base 421, and the hook 424 is sleeved on the circumference of the rotating shaft. The fifth driving member 422 is installed on the second base 421 and connected to the rotating shaft to drive the hook 424 to hook or unhook with the hook shaft.

[0050] When no command is received, the hook 424 remains engaged with the hook shaft, and the entire unhooking mechanism 4 is securely connected to the first clamping assembly 51 or the winding assembly 32. When it is necessary to maintain the connection, the hook 424, driven by the fifth drive member 422, rotates to engage tightly with the hook shaft, forming a secure hook. The hook state is achieved through the mechanical structure between the hook 424 and the hook shaft, ensuring that they will not accidentally separate during operation.

[0051] When separation is required, the fifth drive unit 422 receives the unhooking command and starts working, driving the rotating shaft to rotate. The rotation of the rotating shaft causes the hook 424 to rotate, causing the hook 424 to disengage from the hook shaft. As the hook 424 is completely disengaged, the connection between the second connecting seat 423 and the second base 421 is released, thereby achieving unhooking.

[0052] It should be noted that this embodiment also includes a paddle 425 and two second displacement sensors 426. The two second displacement sensors 426 are spaced apart on the second base 421. By rotating the paddle 425, its cooperation with the second displacement sensors 426 causes the hook 424 to move to a designated position, thereby controlling the opening and closing of the fifth driving member 422.

[0053] In this embodiment, the interface of the UAV 1 is a dedicated remote controller, operating in the 422-433MHz frequency band and capable of 100 levels of frequency hopping, meaning that 100 sets of various devices can simultaneously transmit data and control within the same area. The effective control range is 1000m (open space). The remote controller not only needs to send commands but also receive information on the execution status of each actuator, sensor readings, and the status of position sensors. Furthermore, after receiving a sleep command, the grounding mechanism 3 shuts down all peripherals and automatically wakes up every 5 seconds to check if the values ​​of peripherals, such as sensors, are normal. If not, it adjusts the values ​​via the driver. During this period, if a wake-up command is received from the remote controller, the grounding mechanism 3 will be fully awakened; otherwise, it will re-enter sleep mode. All of the above functions are controlled by the second control unit 33 of the grounding mechanism 3, which includes the MCU, driver module, and communication module PCB board. Similarly, the wire end mechanism 5 has the same functions.

[0054] In summary, this invention provides a grounding wire attachment device that, through the precise control system of the UAV 1 and the additional support provided by the linkage 2, maintains a relatively stable attitude in the air, thereby reducing the risk of tipping over. Furthermore, the use of a mechanical clamping assembly instead of ropes improves the reliability of the attachment process. Simultaneously, the first control unit 52 and the second control unit 33 allow remote activation of the clamping assembly and disengagement action, enabling most operations to be remotely controlled by ground station personnel, significantly reducing manpower requirements and improving work efficiency. Finally, the detachable connection method allows for operation entirely by the UAV 1, eliminating the need for personnel to climb.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
