Description

Technical Field

[0001] This invention relates to the field of power maintenance technology, specifically to an externally powered drone grounding wire attachment and removal device. Background Technology

[0002] Installing grounding wires is a crucial preliminary measure in power maintenance, used to eliminate residual and induced voltages, ensuring personnel safety and preventing accidents. Traditional manual methods of climbing towers to install and remove grounding wires suffer from drawbacks such as high risks at heights, high labor intensity, low efficiency, and poor adaptability, making it difficult to meet the current demands for large-scale, safe, and efficient power maintenance operations. To overcome the shortcomings of manual operations, existing technology utilizes drones equipped with grounding wire installation and removal devices. This device leverages the high-altitude flexibility of drones to achieve automated and unmanned installation and removal, mitigating safety risks and improving intelligence and efficiency, and has been widely applied in the field of power maintenance.

[0003] Currently, the clamping mechanisms for attaching and detaching grounding wires on drones all adopt an integrated structure where the power supply unit and the clamping device body are integrated. The power supply unit built into the body provides power for the driving, control, and pressure holding operations of the clamping mechanism. This traditional integrated power supply structure has significant technical drawbacks, resulting in poor equipment adaptability and low operational reliability. Specific defects are as follows: First, power maintenance operations have long cycles, with routine maintenance lasting more than ten days, and maintenance and modification of complex lines and equipment sometimes taking up to a month. The battery capacity of the power supply unit integrated into the device is limited, and its endurance cannot meet the needs of long-cycle maintenance operations.

[0004] Secondly, drone grounding wire attachment / removal devices are used in outdoor environments, enduring harsh conditions such as sun exposure, rain, and sandstorms for extended periods. Therefore, they require extremely high waterproof, dustproof, and corrosion-resistant properties. While existing integrated power supply structures are fully sealed, they are still prone to seal failure, wiring aging, and component damage under long-term outdoor conditions. This can lead to leakage, short circuits, clamping mechanism malfunction, and grounding wire fixation failure, posing electrical safety risks. Furthermore, the increased failure rate shortens the device's lifespan, increases maintenance and replacement costs, and hinders its large-scale reliable application in long-term outdoor maintenance.

[0005] In summary, existing drones equipped with grounding wire attachment and removal devices generally suffer from technical defects such as insufficient endurance for long-term maintenance operations, poor adaptability to outdoor environments, high risk of leakage and component damage, and poor operational reliability, thus failing to meet the needs of complex and long-term power maintenance operations. Summary of the Invention

[0006] In response to the problems of existing integrated grounding wire hanging and removing devices for power supply units being unable to adapt to long-term maintenance operations, having poor adaptability to outdoor environments, and having low reliability, this application provides an externally powered UAV grounding wire hanging and removing device that can effectively solve the endurance bottleneck and outdoor environment adaptability problems in long-term maintenance operations.

[0007] The technical solution adopted by this invention to solve its technical problem is: An externally powered UAV grounding wire attachment and removal device includes a mounting pole, a pole / tower clamping assembly, and a conductor clamping assembly. The mounting pole is provided with two mounting assemblies for attaching the pole / tower clamping assembly and the conductor clamping assembly, respectively. The mounting assembly includes a mounting frame, which has an upward-facing recess, and the mounting frame is equipped with a magnetic coupling drive rotor and a drive motor for driving the drive rotor to rotate. The pole / tower clamping assembly includes a first frame, on which a first clamping groove and a first mounting groove are provided. A pole / tower clamping moving plate is slidably disposed in the first clamping groove of the first frame. A first lead screw is rotatably disposed on the first frame for driving the pole / tower clamping moving plate to move. A first driven rotor is disposed on the first lead screw. When the first mounting groove is engaged with the recessed part, the driving rotor and the first driven rotor form a non-contact power transmission. The wire clamping assembly structure includes a second frame, on which a second clamping groove and a second mounting groove are provided. A wire clamping moving block is slidably disposed in the second clamping groove of the second frame. A second lead screw is rotatably disposed on the second frame to drive the wire clamping moving block to move. A second driven rotor is disposed on the second lead screw. When the second mounting groove is engaged with the recessed part, the driving rotor and the second driven rotor form a non-contact power transmission.

[0008] Furthermore, a rotating shaft is provided on the mounting frame below the recessed portion. One end of the rotating shaft is rotatably connected to the mounting frame, and the other end of the rotating shaft is connected to the power output end of the drive motor. The active rotor is fixedly sleeved on the rotating shaft. First guide members extending obliquely outward and upward are respectively provided on both ends of the recessed portion of the mounting frame.

[0009] Furthermore, the mounting frame is provided with a locking mechanism, which includes a locking block that is hinged to the mounting frame in the middle. One end of the locking block faces the recess of the mounting frame, and the other end of the locking block is hinged to the driving end of the driving member. When the driving end of the driving member extends, the end of the locking block facing the recess can press down to clamp the pole / tower clamping part or the conductor clamping part that is mounted on the mounting frame.

[0010] Furthermore, the mounting frame is provided with mounting holes for accommodating the mounting rod, and the mounting rod is connected and fixed to the mounting frame by a positioning pin.

[0011] Furthermore, the openings of the first clamping groove and the first mounting groove both face downwards. The first lead screw extends into the first mounting groove. The first driven rotor is located in the first mounting groove and is fixedly connected to the first lead screw. A mounting plate is provided in the first mounting groove below the first driven rotor. When the pole position clamping part is mounted on the mounting part, the pole position clamping part straddles the recess of the mounting part, and the bottom surface of the recess is in contact with the mounting plate. Two first guide rods are provided in the first clamping groove below the first lead screw. A first nut and a first guide sleeve are provided on the pole position clamping moving plate.

[0012] Furthermore, the pole clamping moving plate includes, from top to bottom, a clamping part and a first guide part. The first guide part extends obliquely downward in a direction away from the first mounting groove. A first rib is provided between the clamping part and the first guide part. The side wall of the first mounting groove away from the first clamping groove includes, from top to bottom, a limiting part and a second guide part. The second guide part extends obliquely downward in a direction away from the first clamping groove. A second rib is provided between the limiting part and the second guide part.

[0013] Furthermore, the pole clamping plate is provided with an elastic clamping assembly, which includes a clamping seat. A plurality of clamping pins are slidably arranged on the clamping side of the clamping seat, and an elastic element is provided between the clamping pins and the clamping seat to prevent the clamping pins from retracting.

[0014] Furthermore, the opening of the second mounting slot faces downward, the opening of the second clamping slot faces horizontally to the side opposite to the second mounting slot, the upper end of the second lead screw extends to the upper side of the second clamping slot, the second driven rotor is located on the upper side of the second clamping slot and is fixedly connected to the second lead screw, when the wire clamping part is mounted on the mounting part, the wire clamping part straddles the recess of the mounting part, and the bottom surface of the recess is in contact with the top surface of the second mounting slot.

[0015] Furthermore, the wire clamping moving block is provided with a first arc-shaped groove, and the upper side wall of the second clamping groove is provided with a wire clamping fixed block. The wire clamping fixed block is provided with a second arc-shaped groove. In the clamping state, the first arc-shaped groove and the second arc-shaped groove together form a wire receiving cavity. The side wall of the second mounting groove away from the second clamping groove is provided with a second guide extending obliquely downward in the direction away from the second clamping groove. The outer end of the wire clamping fixed block is provided with a second guide extending obliquely downward in the direction away from the second mounting groove.

[0016] Furthermore, the mounting rod is composed of several vertical rods connected end to end in sequence, with adjacent vertical rods connected by universal joints. Both mounting components are mounted on the lowest vertical rod, and the mounting rod is equipped with a power supply module for providing power to the two mounting components.

[0017] The beneficial effects of this invention are: This application provides an externally powered UAV grounding wire attachment / removal device. By separating the power supply module from the clamping mechanism and using a magnetic coupling to achieve non-contact power transmission, it effectively overcomes the technical drawbacks of existing integrated power supply structures and has the following advantages: 1. Overcoming the bottleneck of endurance in long-cycle operations: This application places the power supply module externally within the clamping mechanism body. Compared to existing technologies that integrate the battery into the clamping mechanism, the duration of a single operation is no longer limited by the built-in battery capacity, effectively adapting to the needs of long-cycle power maintenance operations lasting several days or even a month. Furthermore, the independent design of the power supply module from the clamping mechanism eliminates the need for reserved space for battery installation and sealing structures within the clamping mechanism body, resulting in a lighter overall weight.

[0018] 2. Significantly Improved Outdoor Environmental Adaptability and Operational Reliability: This application separates the power supply unit from the clamping device body, eliminating any electrical components within the clamping mechanism body. The core advantage of this structural change is that the clamping mechanism body achieves a truly purely mechanical structure, eliminating the need for any moving sealing surfaces for battery replacement or charging interfaces. This fundamentally eliminates the risk of electrical faults such as leakage and short circuits caused by aging seals and wiring. The fault isolation mechanism between the clamping mechanism body and the power supply module significantly improves the overall outdoor environmental adaptability and operational reliability of the equipment.

[0019] 3. Magnetic coupling enables safe, non-contact power transmission: Power is transmitted between the mounting assembly and the clamping assemblies at the tower and conductor positions via magnetic couplings, with no direct mechanical contact between the driving and driven rotors. This design offers multiple advantages: First, no electrical interface is required between the clamping mechanism and the mounting assembly, further enhancing the fully sealed characteristics of the clamping mechanism; second, the magnetic coupling method allows for a certain degree of alignment deviation during the mounting process, reducing the accuracy requirements for UAV hovering and making the mounting operation more convenient and reliable; third, when the clamping mechanism is overloaded, the magnetic coupling can automatically slip, providing overload protection and preventing excessive clamping force from damaging the tower angle steel or conductors, while also preventing the drive motor from burning out due to stalling.

[0020] 4. The tower clamping assembly generates active clamping force through a screw-driven clamping plate, while simultaneously using an adaptive clamping pin in the elastic clamping component to create a mechanical limit. The clamping pin, not in contact with the angle steel, extends under the action of the elastic element and is positioned below the angle steel, effectively restricting the upward movement of the clamping assembly relative to the tower angle steel. This dual locking mechanism of "active clamping + elastic limiting" significantly enhances vibration and disturbance resistance compared to existing clamping schemes that rely solely on friction. Even under strong winds at high altitudes or airflow disturbances from drone propellers, it ensures the stability of the grounding wire connection. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0024] To facilitate understanding of the specific embodiments of this application, a coordinate system is now defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0025] Example 1 like Figure 1 and Figure 4As shown, an externally powered UAV grounding wire attachment / removal device includes a mounting rod 1, a tower clamping assembly 2, a conductor clamping assembly 3, and a power supply module 5. The mounting rod 1 has two detachable mounting assemblies 4, which are used to attach to the tower clamping assembly 2 and the conductor clamping assembly 3, respectively. The tower clamping assembly 2 clamps the tower angle steel 6, and the conductor clamping assembly 3 clamps the transmission conductor 7. The tower clamping assembly 2 and the conductor clamping assembly 3 are connected via a grounding wire (not shown in the figure).

[0026] The mounting assembly 4 includes a mounting frame 41, which has an upward-facing recess 415. A drive motor 42 and a magnetic coupling's drive rotor 43 are mounted on the mounting frame 41. The power output shaft of the drive motor 42 is connected to the magnetic coupling's drive rotor 43, which rotates around its own axis under the drive of the drive motor 42. The power supply module 5 provides electrical energy to the drive motor 42 of the mounting assembly 4.

[0027] Preferably, the power supply module 5 is detachably fixed to the mounting rod 1.

[0028] The pole / tower clamping assembly 2 includes a first frame 21. The first frame 21 is provided with a first clamping groove 2151 and a first mounting groove 2152 with the opening facing downward. The first mounting groove 2152 matches the recess 415 on the mounting frame 41 for quick positioning and stable attachment. A pole / tower clamping moving plate 22 is slidably disposed on the first frame 21 within the first clamping groove 2151. A first lead screw 23 is rotatably disposed on the first frame 21 to drive the pole / tower clamping moving plate 22 to reciprocate. A first driven rotor 24 is provided at one end of the first lead screw 23.

[0029] When the pole / tower clamping part 2 is attached to the mounting part 4, the active rotor 43 on the mounting part 4, which is used to attach the pole / tower clamping part 2, forms a complete magnetic coupling with the first driven rotor 24. The first lead screw 23 is driven to rotate through non-contact power transmission, which drives the pole / tower clamping moving plate 22 to move, thereby realizing adaptive clamping and reliable locking of the pole / tower angle steel 6.

[0030] The wire clamping assembly 3 includes a second frame 31, on which a second clamping groove 3172 and a second mounting groove 3171 with an opening facing downwards are provided. The opening of the second clamping groove 3172 is horizontally oriented towards the side opposite to the second mounting groove 3171. The second mounting groove 3171 matches the recess 415 on the mounting frame 41 for quick positioning and stable attachment. A wire clamping moving block 32 is slidably disposed on the second frame 31 within the second clamping groove 3172. A second lead screw 33 is rotatably disposed on the second frame 31 for driving the wire clamping moving block 32 to move up and down. A second driven rotor 34 is disposed at one end of the second lead screw 33.

[0031] When the wire clamping part 3 is attached to the mounting part 4, the active rotor 43 and the second driven rotor 34 on the mounting part 4, which are used to attach the wire clamping part 3, form a complete magnetic coupling. The second lead screw 33 is driven to rotate through non-contact power transmission, which drives the wire clamping moving block 32 to move vertically upward, thereby achieving reliable clamping of the wire.

[0032] like Figure 4 , Figure 5 and Figure 6 As shown, the mounting frame 41 includes a first vertical plate 411, a second vertical plate 412, and a third vertical plate 413 arranged in parallel. A first connecting plate 414 is provided between the first vertical plate 411 and the second vertical plate 412, and the first vertical plate 411, the second vertical plate 412, and the first connecting plate 414 together form an upward-facing recess 415, providing a common mounting reference for the pole clamping assembly 2 and the conductor clamping assembly 3. A second connecting plate 416 is provided between the second vertical plate 412 and the third vertical plate 413. The first vertical plate 411, the second vertical plate 412, the third vertical plate 413, the first connecting plate 414, and the second connecting plate 416 together form a rigid frame structure, effectively improving the overall load-bearing capacity and torsional stiffness. The drive motor 42 is located between the second vertical plate 412 and the third vertical plate 413, and below the second connecting plate 416. The tail end of the drive motor 42 is fixedly connected to the third vertical plate 413 by bolts. A rotating shaft 44 is disposed between the first vertical plate 411 and the second vertical plate 412, below the recess 415. One end of the rotating shaft 44 is rotatably connected to the first vertical plate 411 via a bearing assembly, and the other end of the rotating shaft 44 passes through the second vertical plate 412 and is fixedly connected to the power output end of the drive motor 42. The driving rotor 43 of the magnetic coupling is fixedly sleeved on the rotating shaft 44 and is located between the first vertical plate 411 and the second vertical plate 412.

[0033] In one specific embodiment, the first connecting plate 414 in this embodiment includes a web and wing plates located on both sides of the web. The web and wing plates together form a U-shaped structure with the opening facing downwards. The driving rotor 43 of the magnetic coupling is located within the space enclosed by the web and wing plates of the U-shaped structure, ensuring that it is not interfered with by the structure during rotation. A slot is provided in the middle of the web, and the slot penetrates the web in a direction parallel to the rotating shaft 44.

[0034] like Figure 2 and Figure 3 As shown, the mounting frame 41 is provided with a mounting hole 4171 for accommodating the mounting rod 1, and the mounting hole 4171 is a through hole. The mounting frame 41 is provided with a positioning pin that radially penetrates the mounting hole 4171, and the mounting rod 1 is provided with a positioning pin hole for accommodating the positioning pin. The mounting rod 1 passes through the two mounting holes 4171 of the mounting components 4 sequentially from top to bottom, and is locked to the mounting frame 41 by the positioning pin, achieving quick assembly / disassembly and reliable positioning.

[0035] As one specific implementation method, such as Figure 5 and Figure 6 As shown, in this embodiment, a mounting plate 417 is provided at one end of the mounting frame 41 away from the recess 415. A boss is provided on the upper side of the suspended end of the mounting plate 417. A mounting hole 4171 is provided on the boss, which penetrates the mounting plate 417 in a vertical direction. The positioning pin is provided on the boss and penetrates the boss in a radial direction along the mounting hole 4171.

[0036] Preferably, the positioning pin is a ball-head locking pin 45.

[0037] Furthermore, the mounting frame 41 is also provided with a locking mechanism, which is used to lock the pole / tower clamping part 2 or the conductor clamping part 3 attached to the mounting frame 41 to prevent them from shifting or loosening during operation.

[0038] like Figure 2 , Figure 5 and Figure 6As shown, the upper surface of the third vertical plate 413 is fixedly connected to the lower surface of the second connecting plate 416 by bolts. One end of the second connecting plate 416 is fixedly connected to the second vertical plate 412, and the other end of the second connecting plate 416 extends to the outside of the third vertical plate 413 (with the side facing the second vertical plate 412 as the inside). The locking mechanism includes a locking block 461 located on the upper side of the second connecting plate 416. The locking block 461 has an overall Z-shaped structure. The middle part of the locking block 461 is hinged to a hinge seat 462 provided on the second connecting plate 416 via a hinge shaft. The hinge seat 462 is fixedly connected to the second connecting plate 416 by screws. One end of the locking block 461 faces the recess 415 of the mounting frame 41, and the other end of the locking block 461 is hinged to the driving end of the driving member. When the drive end of the drive component extends, the locking block 461 rotates around the hinge axis. The end of the locking block 461 facing the recess 415 presses down to clamp the pole position clamping part 2 or the conductor position clamping part 3 that is attached to the mounting frame 41, ensuring that it remains stable during high-altitude operations. When the drive component retracts, the locking block 461 resets, facilitating quick disassembly.

[0039] In one specific embodiment, the driving component described in this embodiment is an electric push rod 463. The lower end of the electric push rod 463 is hinged to the lower end of the third vertical plate 413 via a hinge shaft, and the driving end of the electric push rod 463 is hinged to the other end of the locking block 461 via a hinge shaft.

[0040] In one specific embodiment, the suspended end of the second connecting plate 416 in this embodiment is provided with a clearance notch 4161 with an opening facing away from the third vertical plate 413. The clearance notch 4161 is used to accommodate the electric push rod 463. First support plates 418 are respectively provided on both sides of the clearance notch 4161 on the second connecting plate 416. The mounting plate 417 is located above the electric push rod 463, and both ends of the mounting plate 417 are fixedly connected to the first support plates 418 by screws. The mounting hole 4171 is located on the outer side of the second connecting plate 416 (with the side facing the second vertical plate 412 as the inner side). The axis of the mounting hole 4171 is staggered from the axis of the electric push rod 463 in the horizontal direction to avoid interference between their movements and to optimize the space utilization of the overall structure.

[0041] Furthermore, the mounting frame 41 is provided with first guide members 419 extending obliquely outward and upward at both ends of the recess 415. The two first guide members 419 together form a trumpet-shaped guide structure with one end opening facing upward, which facilitates the smooth sliding of the pole clamping part 2 or the conductor clamping part 3 into the recess 415 along the guide surface, and achieves automatic centering and positioning before locking.

[0042] As one specific implementation method, such as Figure 4 and Figure 5 As shown, in this embodiment, the two first guide members 419 are respectively disposed at the upper ends of the first vertical plate 411 and the second vertical plate 412.

[0043] like Figure 7 , Figure 8 and Figure 9 As shown, the first frame 21 includes a first top plate 211. A first upright plate 212, a second upright plate 213, and a third upright plate 214 are sequentially arranged on the lower side of the first top plate 211 along its length. The first top plate 211, the first upright plate 212, and the second upright plate 213 together form the first clamping groove 2151, and the first top plate 211, the second upright plate 213, and the third upright plate 214 together form the first mounting groove 2152.

[0044] Furthermore, first stiffening plates 216 are respectively provided on both sides of the first upright plate 212 between the first upright plate 212 and the first top plate 211. The first stiffening plates 216 have a right-angled triangular structure, and their right-angled sides are fixedly connected to the first upright plate 212 and the first top plate 211, effectively enhancing the connection stiffness and bending resistance between the first upright plate 212 and the first top plate 211. Similarly, second stiffening plates 217 are respectively provided on both sides of the second upright plate 213 between the second upright plate 213 and the first top plate 211. The second stiffening plates 217 also have a right-angled triangular structure, and their right-angled sides are fixedly connected to the second upright plate 213 and the first top plate 211.

[0045] The first lead screw 23 includes a first transmission section with external threads. One end of the first transmission section is coaxially provided with a first connecting section, which is rotatably connected to the first upright plate 212 via a bearing assembly. The other end of the first transmission section is coaxially provided with a second connecting section, which extends through the second upright plate 213 into the first mounting groove 2152 and is rotatably connected to the second upright plate 213 and the third upright plate 214 via a bearing assembly. The first driven rotor 24 is located within the first mounting groove 2152 and is coaxially and fixedly connected to the second connecting section of the first lead screw 23. A mounting plate 218 is provided below the first driven rotor 24 within the first mounting groove 2152.

[0046] like Figure 13 and Figure 15As shown, when the pole clamping part 2 is attached to the mounting part 4, the mounting part 4 is located in the first mounting groove 2152 of the pole clamping part 2, the pole clamping part 2 straddles the recess 415 of the mounting part 4, and the upper side plane of the first connecting plate 414 is in close contact with the lower side plane of the mounting plate 218, so as to achieve reliable attachment.

[0047] In one specific embodiment, the structure of the mounting plate 218 is similar to that of the first connecting plate 414, including a web and wing plates located at both ends of the web. The web and wing plates together form a U-shaped structure with the opening facing upwards. The mounting plate 218, the first top plate 211, the second vertical plate 213, and the third vertical plate 214 together form an installation space for accommodating the first driven rotor 24. A slot is provided in the middle of the web, and the slot penetrates the web in a direction parallel to the first lead screw 23.

[0048] like Figure 8 , Figure 9 and Figure 10 As shown, two first guide rods 25, arranged parallel to the first lead screw 23, are disposed in the first clamping groove 2151 below the first lead screw 23. One end of the first guide rod 25 is detachably fixedly connected to the first upright plate 212, and the other end of the first guide rod 25 is detachably fixedly connected to the second upright plate 213. The pole position clamping moving plate 22 is provided with a first nut 231 that cooperates with the transmission section of the first lead screw 23 and a first guide sleeve 251 that cooperates with the first guide rods 25. Both the first nut 231 and the first guide sleeve 251 are detachably fixedly connected to the pole position clamping moving plate 22. Preferably, the first guide sleeve 251 is a linear bearing.

[0049] The first guide rod 25 not only provides precise guidance and constraint for the pole position clamping moving plate 22, but also acts as a load-bearing component in contact with the pole angle steel 6. During installation, after the pole position clamping assembly 2 is hoisted to the predetermined position, it is slowly lowered so that the pole angle steel 6 enters between the pole position clamping moving plate 22 and the second vertical plate 213, until the pole angle steel 6 contacts the outer surface of the first guide rod 25. At this time, the two first guide rods 25 are tightly fitted with the upper wing surface of the pole angle steel 6, forming a stable support structure. Then, the drive motor 42 of the mounting assembly 4 is activated, driving the first driven rotor 24 to rotate synchronously through the active rotor 43 of the magnetic coupling, which in turn drives the first lead screw 23 to rotate; the first lead screw nut 231 then moves axially along the first lead screw 23, pushing the pole position clamping moving plate 22 to slide smoothly along the first guide rod 25 until the pole angle steel 6 is firmly clamped between the pole position clamping moving plate 22 and the second vertical plate 213, completing the adaptive clamping.

[0050] Furthermore, the pole clamping moving plate 22, from top to bottom, includes a clamping part 221 and a first guide part 222. The clamping part 221 is vertical, and the first guide part 222 extends obliquely downward away from the second vertical plate 213. The first guide part 222 and the second vertical plate 213 together form a wedge-shaped guide structure for guiding the pole angle steel 6 to slide smoothly into the clamping area. A first rib 223 is provided between the clamping part 221 and the first guide part 222. The third vertical plate 214, from top to bottom, includes a limiting part 2141 and a second guide part 2142. The limiting part 2141 is vertical, and the second guide part 2142 extends obliquely downward away from the second vertical plate 213. The second guide part 2142 and the second vertical plate 213 together form a wedge-shaped guide structure for guiding the mounting part 4 to slide smoothly into the area. A second rib 2143 is provided between the limiting part 2141 and the second guide part 2142 to enhance the overall rigidity and guiding stability.

[0051] Furthermore, such as Figure 8 and Figure 10 As shown, one or both sides of the pole position clamping moving plate 22 are provided with elastic clamping components 26.

[0052] In one specific implementation, elastic clamping components 26 are provided on both sides of the pole clamping moving plate 22 in this embodiment.

[0053] like Figure 9 and Figure 11 As shown, the elastic clamping assembly 26 includes a clamping seat 261. The upper and lower ends of the clamping seat 261 are fixedly connected to the side of the clamping portion 221 of the tower clamping moving plate 22 by screws. A plurality of clamping pins are slidably disposed on the side of the clamping seat 261 facing the second vertical plate 213. An elastic element is disposed between the clamping pins and the clamping seat 261 to prevent the clamping pins from retracting. Preferably, the plurality of clamping pins are evenly arranged in the vertical direction.

[0054] In one specific embodiment, six clamping pins are evenly distributed vertically on the clamping seat 261. The clamping seat 261 has guide holes for accommodating the clamping pins, and these guide holes penetrate the clamping seat 261. Each clamping pin includes a pin shaft 262. A limiting boss 2621 is provided on the side of the clamping seat 261 facing away from the second vertical plate 213, and the limiting boss 2621 is integrally formed with the pin shaft 262. A limiting baffle 263 is provided at the end of the pin shaft 262 facing the second vertical plate 213. A stud 2631 is provided on the limiting baffle 263, and the stud 2631 is integrally formed with the limiting baffle 263. A threaded hole that mates with the stud 2631 is provided on the end face of the pin shaft 262. A spring 264 and a spacer 265 are sequentially fitted onto the pin 262, and the spacer 265 is pressed against the limiting baffle 263 by the spring 264. The outer diameter of the spacer 265 matches the inner diameter of the guide hole, forming a good guiding fit.

[0055] like Figure 12 As shown, when the tower angle steel 6 is clamped, the clamping pins that are not in contact with the tower angle steel 6 will be extended, while the clamping pins that are in contact with the tower angle steel 6 will be compressed into the clamping seat 261. In this way, firstly, it can adapt to the dimensional deviations of tower angle steel 6 of different specifications; secondly, it can reduce the installation requirements, and even if it is not installed in the preset position as expected, reliable clamping can be achieved through the adaptive adjustment of the elastic clamping component 26; thirdly, the clamping pins located on the lower side of the tower angle steel 6 are in the extended state, which can limit the degree of freedom of the tower position clamping component 2 to move upward relative to the tower angle steel 6, which significantly improves the clamping reliability and anti-disturbance ability compared to the solution that relies solely on friction to achieve clamping.

[0056] Furthermore, such as Figure 9 As shown, a detachable first operating component 232 is fixedly installed at one end of the first lead screw. The first operating component 232 allows the first lead screw to be manually rotated, thereby driving the tower clamping plate 22 to reciprocate horizontally, achieving precise clamping and release of the tower angle steel 6. The first operating component 232 serves as an emergency handle, providing a last line of manual protection in case of failure or emergency.

[0057] In one specific implementation, the first operating element 232 described in this embodiment is disposed at the end of the first lead screw 23 away from the driving rotor 43 of the magnetic coupling.

[0058] Furthermore, such as Figure 13 and Figure 14As shown, a first locking plate 219 is provided on the first top plate 211 above the first mounting slot 2152. One end of the first locking plate 219 is fixedly connected to the first top plate 211 by screws. When the pole position clamping part 2 is attached to the mounting part 4, the other end of the first locking plate 219 faces the locking mechanism and can cooperate with the locking block 461 of the locking mechanism, so that the locking block 461 presses against the first locking plate 219, thereby restricting the axial movement of the pole position clamping part 2 along the mounting direction and improving the overall rigidity and impact resistance stability in the attached state.

[0059] like Figure 16 , Figure 17 and Figure 18 As shown, the second frame 31 includes a second top plate 311. One end of the second top plate 311 has a first support plate 312 extending downwards perpendicular to the second top plate 311, and the other end has a second support plate 313 extending downwards perpendicular to the second top plate 311. On the side of the second support plate 313 facing away from the first support plate 312, a first horizontal plate 314, a second horizontal plate 315, and a third horizontal plate 316 are arranged sequentially from top to bottom. The second top plate 311, the first support plate 312, and the second support plate 313 together form the second mounting groove 3171; the second support plate 313, the first horizontal plate 314, and the second horizontal plate 315 together form the second clamping groove 3172, and the opening of the second clamping groove 3172 faces away from the second mounting groove 3171.

[0060] Furthermore, reinforcing side plates 318 are provided on both sides of the second support plate 313 between the second horizontal plate 315 and the third horizontal plate 316. The upper and lower ends of the reinforcing side plates 318 are fixedly connected to the second horizontal plate 315 and the third horizontal plate 316 respectively. The end of the reinforcing side plate 318 facing the second support plate 313 is fixedly connected to the second support plate 313 by screws.

[0061] The second lead screw includes a second transmission section with external threads. A third connecting section is coaxially disposed at the lower end of the second transmission section, and the third connecting section is rotatably connected to the third horizontal plate 316 via a bearing assembly. A fourth connecting section is coaxially disposed at the upper end of the second transmission section. The fourth connecting section passes sequentially through the second horizontal plate 315 and the first horizontal plate 314, and is rotatably connected to both the second horizontal plate 315 and the first horizontal plate 314 via a bearing assembly. The second driven rotor 34 is located between the first horizontal plate 314 and the second horizontal plate 315, and is coaxially and fixedly connected to the fourth connecting section of the second lead screw 33.

[0062] like Figure 19 , Figure 20 and Figure 21As shown, when the wire clamping part 3 is attached to the mounting part 4, the mounting part 4 is located in the second mounting groove 3171 of the wire clamping part 3, and the wire clamping part 3 straddles the recess 415 of the mounting part 4. The upper plane of the first connecting plate 414 is in close contact with the lower plane of the second top plate 311, achieving reliable attachment. At this time, the driving rotor 43 of the mounting part 4 used to attach the wire clamping part 3 forms magnetic coupling with the second driven rotor 34 of the wire clamping part 3, achieving non-contact power transmission and transmitting the power of the drive motor 42 to the second lead screw 33, thereby driving the second lead screw to rotate.

[0063] like Figure 17 and Figure 18 As shown, the second clamping groove 3172 is provided with two second guide rods 35 arranged parallel to the second lead screw 33. The upper end of the second guide rod 35 is detachably fixed to the second horizontal plate 315, and the lower end is detachably fixed to the third horizontal plate 316. The two second guide rods 35 are located on both sides of the second lead screw, and the second guide rods 35 and the second lead screw 33 are arranged in a straight line. The wire clamping moving block 32 is provided with a second nut 331 that cooperates with the second lead screw 33 and a second guide sleeve 351 that cooperates with the second guide rod 35. The second guide sleeve 351 slides with the second guide rod 35 to ensure that the wire clamping moving block 32 moves smoothly along the axial direction. Preferably, the second guide sleeve 351 is a linear bearing. The upper side of the end of the wire clamping moving block 32 facing the opening of the second clamping groove 3172 is provided with a first arc-shaped groove 321 for accommodating the wire.

[0064] Furthermore, such as Figure 16 , Figure 17 and Figure 21 As shown, a wire clamping block 36 is provided on the lower side of the second horizontal plate 315. The lower end of the wire clamping block 36 is provided with a second arc-shaped groove 361 for accommodating the wire. The first arc-shaped groove 321 and the second arc-shaped groove 361 are aligned. When the wire clamping moving block 32 moves upward under the drive of the second lead screw, the first arc-shaped groove 321 and the second arc-shaped groove 361 together form a wire receiving cavity, which firmly clamps the wire in the cavity, thereby effectively preventing the wire from slipping or being damaged during the clamping process and ensuring the safety and reliability of power operations.

[0065] Furthermore, the lower end of the first support plate 312 is provided with a second guide member 3121 extending obliquely downward in a direction away from the second support plate 313. The second guide member 3121 and the second support plate 313 together form a wedge-shaped guide structure for guiding the mounting component 4 to slide smoothly into the device. The outer end of the wire clamping block 36 (with the end away from the second support plate 313 as the outer end) is provided with a third guide member 362 extending obliquely downward in a direction away from the second support plate 313. The third guide member 362 is used to guide the wire to slide smoothly into the second arc-shaped groove 361 of the wire clamping block 36.

[0066] Furthermore, such as Figure 18 and Figure 21 As shown, a detachable second operating component 332 is fixedly installed at the lower end of the second lead screw. The second operating component 332 allows manual rotation of the second lead screw, thereby driving the wire clamping moving block 32 to reciprocate vertically, achieving precise clamping and release of the wire. The second operating component 332 serves as an emergency handle, providing a final line of manual protection in case of malfunction or emergency.

[0067] Furthermore, such as Figure 17 and Figure 21 As shown, the width of the first horizontal plate 314 is smaller than the width of the second top plate 311. The first horizontal plate 314 is located above the second top plate 311. One end of the first horizontal plate 314 is fixedly connected to the second top plate 311 by screws, and the other end of the first horizontal plate 314 extends to the side of the second support plate 313 facing away from the first support plate 312. On the second top plate 311, second support plates 3111 extending upwards are respectively provided on both sides of the first horizontal plate 314. On the second horizontal plate 315, third ribs 3151 are respectively provided on both sides of the first horizontal plate 314, and the third ribs 3151 are aligned with the second support plates 3111 one by one. The third ribs 3151 have a triangular structure, with one right-angled side fixedly connected to the second horizontal plate 315, and the other right-angled side fixedly connected to the corresponding second support plate 3111. A second locking plate 319 is provided above the second support plate 3111. One end of the second locking plate 319 is fixedly connected to the two second support plates 3111 by screws. When the wire clamping part 3 is attached to the mounting part 4, the other end of the second locking plate 319 faces the locking mechanism and can cooperate with the locking block 461 of the locking mechanism, so that the locking block 461 presses against the second locking plate 319, thereby restricting the axial movement of the wire clamping part 3 along the mounting direction and improving the overall rigidity and impact resistance stability in the attached state.

[0068] The wire clamping part 221 clamps the wire by clamping it from top to bottom, which can effectively shorten the length of the wire clamping part 221 along the direction perpendicular to the wire, thereby reducing the center of gravity shift and preventing the wire clamping part 221 from rotating around the wire in the clamped state, thus improving the dynamic balance and operational controllability during operation.

[0069] Furthermore, in the upper and lower clamping structure, the surfaces of the first arc-shaped groove 321 of the wire clamping moving block 32 and the second arc-shaped groove 361 of the wire clamping stationary block 36 are both provided with micro-tooth anti-slip structures.

[0070] Furthermore, such as Figure 1 As shown, the mounting rod 1 is composed of several vertical rods 11 connected end to end in sequence. Adjacent vertical rods 11 are connected by universal joints 12. Both mounting components 4 are mounted on the lowermost vertical rod 11. The upper end of the uppermost vertical rod 11 is provided with a connecting plate or connecting structure adapted to the UAV connection end to achieve a stable connection with the UAV connection end.

[0071] This application provides an externally powered drone grounding wire attachment and detachment device, the working process of which is as follows: First, the power supply module 5 is fixed on the mounting pole 1, the mounting pole 1 is connected to the drone, the two mounting components 4 are locked in the predetermined position of the mounting pole 1 by positioning pins, and the pole clamping component 2 and the conductor clamping component 3 are connected by grounding wire and then respectively hung on the two mounting components 4.

[0072] Second, the drone takes off, carrying the mounting pole 1 and mounting component 4 to the work position, and first connects the pole clamping component 2. The operator controls the drone to align the pole clamping assembly 2 with the attachment position of the pole angle steel 6 and slowly lowers it. Under the action of the guide structure, the pole angle steel 6 smoothly slides into the pole clamping moving plate 22 and the second vertical plate 213 of the pole clamping assembly 2. Then, the drive motor 42 is started, which drives the first lead screw 23 to rotate through the magnetic coupling, causing the pole clamping moving plate 22 to move along the first guide rod 25 until the pole angle steel 6 is pressed against the second vertical plate 213. At this time, the clamping pin in the elastic clamping assembly 26 that is in contact with the angle steel is compressed, and the clamping pin that is not in contact remains in the extended state and forms a mechanical limit. Subsequently, the electric push rod 463 of the locking mechanism retracts, the locking mechanism opens, and the drone moves downward, thereby disengaging the mounting assembly 4 from the pole clamping assembly 2, completing the stable attachment on the pole side.

[0073] Third, the drone flies to the wire connection location, and the operator controls the drone to position the wire clamping device 3 at the connection point of the wire, and slowly lowers it. Under the action of the guide structure, the wire smoothly slides into the second arc-shaped groove 361 of the wire clamping device 3. Then, the drive motor 42 is started, which drives the second lead screw 33 to rotate through the magnetic coupling, causing the wire clamping moving block 32 to move upward along the second guide rod 35 until the wire is clamped between the wire clamping moving block 32 and the wire clamping fixed block 36. Subsequently, the electric push rod 463 of the locking mechanism retracts, the locking mechanism opens, and the drone moves downward, thereby disengaging the mounting device 4 from the wire clamping device 3, completing the stable connection of the wire side.

[0074] Fourth, after the maintenance work is completed, the UAV takes off, carrying the mounting rod 1 and mounting component 4 to the work station. First, the recessed part 415 of the mounting component 4 is aligned upward with the second mounting slot 3171 of the wire clamping component 3. Then the UAV rises to complete the attachment. Then the drive motor 42 rotates in the opposite direction to release the wire. At the same time, the electric push rod 463 extends to lock the wire clamping component 3. Subsequently, the UAV rises to smoothly carry the wire clamping component 3 away from the wire.

[0075] Fifth, the drone flies to the tower operation position and aligns the recessed part 415 of another mounting part 4 with the first mounting slot 2152 of the tower clamping part 2. Then the drone rises to complete the mounting. Subsequently, the drive motor 42 rotates in the opposite direction to release the tower angle steel 6. The elastic clamping component 26 then resets. The locking mechanism re-locks the tower clamping part 221 under the action of the extended electric push rod 463. Then the drone rises to smoothly carry the tower clamping part 2 away from the tower angle steel 6.

[0076] Example 2 Remove the first support plate 418 and the mounting plate 417. The second connecting plate 416 is provided with a clearance hole for accommodating the electric push rod 463. The mounting hole 4171 is provided on the second connecting plate 416, and the mounting hole 4171 is located on the side of the clearance hole away from the second vertical plate 412. The remaining structure is the same as in Embodiment 1.

[0077] Example 3 The second connecting section of the first lead screw 23 has a cantilever structure, and the second connecting section is rotatably connected to the second vertical plate 213 only through a bearing assembly. Similarly, if the first horizontal plate 314 is removed, the fourth connecting section of the second lead screw is rotatably connected to the second horizontal plate 315 only through a bearing assembly.

[0078] The rest of the structure is the same as in Example 1.

[0079] Example 4 The end of the second connecting section of the first lead screw 23 is rotatably connected to the third vertical plate 214 via a bearing assembly. The second vertical plate 213 is provided with a clearance hole for accommodating the first lead screw 23. Similarly, the end of the fourth connecting section of the second lead screw is rotatably connected to the first horizontal plate 314 via a bearing assembly. The second horizontal plate 315 is provided with a clearance hole for accommodating the second lead screw.

[0080] The rest of the structure is the same as in Example 1.
