Description

Technical Field

[0001] This invention relates to the field of power grid operation, maintenance and repair technology, and more specifically, to a device and method for attaching and removing grounding wires. Background Technology

[0002] Before carrying out maintenance work on de-energized lines or equipment, grounding wires must be installed. This prevents injuries from induced voltage and effectively avoids personal injury to maintenance personnel due to accidental power restoration. Traditional grounding wire installation usually involves workers carrying the grounding wire up the tower, working layer by layer and phase by phase, and then dismantling it sequentially after completion. This traditional method is physically demanding and carries risks such as injuries from induced voltage and falls from heights. With the widespread use of drones and robots in power line maintenance, combining drones with grounding wire installation technology can effectively improve efficiency and ensure safety. However, existing technologies suffer from limitations in electrical control due to the high-altitude environment, poor reliability of mechanical structures, and insufficient clamping force, leading to the risk of intermittent disconnection of the grounding wire connection.

[0064] Various embodiments of the invention will now be described in more detail with reference to the accompanying drawings. In the various drawings, the same elements are indicated by the same or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0065] This invention provides a grounding wire attachment / removal device, which includes a conductor end attachment / removal device and a tower end attachment / removal device. The conductor end attachment / removal device includes a conductor clamping mechanism 6 and a first ground wire locking mechanism. The conductor clamping mechanism 6 is used to attach and clamp the conductor to the conductor via a drone. The first ground wire locking mechanism is connected to the lower end of the conductor clamping mechanism 6 and is used to lock and fix the high-voltage end of the grounding wire. See also... Figure 1 and Figure 2The pole-end hanging and detaching device includes a hook body 1, an adapter clamping mechanism 2, a top linkage unlocking mechanism 3, and a second ground wire locking mechanism 4. The adapter clamping mechanism is disposed on the hook body 1 and is used to clamp the hook body 1 onto the angle steel of the pole after it is hung on the pole. The top linkage unlocking mechanism 3 is disposed on the top of the hook body 1 and is used to connect with the drone. The top linkage unlocking mechanism 3 is connected to the adapter clamping mechanism 2 through a steel wire rope 51 to control the adapter clamping mechanism 2 to unlock. The second ground wire locking mechanism 4 is disposed at the lower end of the hook body 1 and is used to lock the low-voltage end of the grounding wire.

[0066] The grounding wire hanging and dismantling device can connect the high-voltage end and low-voltage end of the grounding wire using drones, respectively. It is simple and convenient to operate, and the entire operation does not require climbing, which reduces the difficulty of operation and safety risks, and improves the flexibility, reliability and safety of grounding wire connection.

[0067] See Figure 3 In the pole end hook-and-unhook device, the hook body 1 includes two hook side plates 11 spaced apart, and a plurality of fixed support blocks 12 fixedly connected between the two hook side plates 11; the hook side plates 11 include a first vertical plate 111 and a second vertical plate 112 spaced apart vertically, and a horizontal plate 113 connected to the top of the first vertical plate 111 and the second vertical plate 112; two clamping support blocks 13 are also provided between the two hook side plates 11, and the two clamping support blocks 13 are respectively located at the upper end of the first vertical plate 111 and the upper end of the second vertical plate 112; the adapter clamping mechanism 2 is rotatably disposed between the two clamping support blocks 13.

[0068] Specifically, the hook side plate 11 has a hook-shaped structure with its opening facing downwards. The length of the first vertical plate 111 of the hook side plate 11 is less than the length of the second vertical plate 112. The width of the lower end of the second vertical plate 112 where it connects to the second ground wire locking mechanism 4 is larger to facilitate the arrangement of the second ground wire locking mechanism 4. The hook side plate 11 is cut from a steel plate of a certain thickness. While meeting the strength requirements, the hook side plate 11 also has several elongated oval holes for weight reduction to reduce the overall weight of the device and facilitate carrying and attaching to the drone. The fixed support block 12 and the clamping support block 13 are respectively fixedly connected to the two hook side plates 11 by screws to achieve the connection and fixation between the two hook side plates 11. The hook body 1 serves as the main mounting frame of the pole end attachment and removal device. The top linkage unlocking mechanism 3, the adapter clamping mechanism 2, and the second ground wire locking mechanism 4 are all installed on the hook body 1.

[0069] See Figure 4 and Figure 5The adapter clamping mechanism 2 includes a rotating seat 21, a hook plate 22, a lifting plate 23, a sliding seat 24, a clamping plate 25, an unlocking piece 26, and an unlocking plate 27. The rotating seat 21 is rotatably connected to the hook body 1 at both ends along its length, and a first compression spring 216 is provided on the rotating seat 21 along its length. The sliding seat 24 is slidably connected to the rotating seat 21 along its length, and the clamping plate 25 is connected to the sliding seat 24, with the clamping plate 25 located below the rotating seat 21. The unlocking piece 26 is rotatably connected to the sliding seat 24, and includes a blocking end 261 and a pressure-bearing end 262. The blocking end 261 can abut against one end of the first compression spring 216. The first end of the hook plate 22 is rotatably connected to the sliding seat 24, and the second end of the hook plate 22 is provided with a downwardly extending portion. The hook is used to engage with the corresponding engagement hole 241 on the sliding seat 24. When the hook plate 22 is engaged with the engagement hole 241 of the sliding seat 24, the unlocking piece 26 on the sliding seat 24 blocks the compression of the first compression spring 216, so that the first compression spring 216 is in a compressed state. The lifting plate 23 is connected to the hook plate 22 by a pin 221, and the lifting plate 23 is located outside the width direction of the rotating seat 21. When the hook plate 22 is engaged with the engagement hole 241 of the sliding seat 24, one end of the lifting plate 23 is located below the rotating seat 21. The two ends of the rotating seat 21 are vertically provided with guide shafts 214, and the two ends of the unlocking plate 27 are slidably disposed on the two guide shafts 214. The top linkage unlocking mechanism 3 is connected to the unlocking plate 27 by a steel wire rope 51.

[0070] See Figure 6The rotating seat 21 has a groove-shaped structure and includes a base plate and two end plates, which are vertically connected to the two ends of the base plate along its length. A contact copper plate 215 is provided at the bottom of the rotating seat 21. By providing the contact copper plate 215 at the bottom of the rotating seat 21, the rotating seat 21 can fit against the angle steel at the tower end, increasing the contact surface and reducing the grounding resistance. A grooved wheel seat 213 is provided on each of the two end plates, and a grooved wheel 52 is rotatably connected to the grooved wheel seat 213. The grooved wheel 52 is used to guide the wire rope 51. The hook body 1 is also provided with several grooved wheels 52. The wire rope 51, drawn from the top linkage unlocking mechanism 3, is guided by the grooved wheels 52 on the hook body 1 and the rotating seat 21 before connecting to the unlocking plate 27. Each of the two grooved wheel seats 213 has a guide shaft 214 vertically mounted on its top. A second compression spring 217 is fitted onto the guide shaft 214. The lower end face of the unlocking plate 27 abuts against the upper end of the second compression spring 217. A top baffle for preventing the unlocking plate 27 from dislodging is provided at the top of the guide shaft 214. By setting the second compression spring 217 on the guide shaft 214, the top linkage unlocking mechanism 3 pulls the steel wire rope 51 to move the unlocking plate 27 downward along the guide shaft 214, pressing the unlocking piece 26 to unlock. After unlocking, the unlocking plate 27 can automatically reset under the elastic force of the second compression spring 217.

[0071] Furthermore, the first compression spring 216, unlocking plate 26, clamping plate 25, and lifting plate 23 are all arranged in two symmetrical positions about the center of the width direction of the rotating seat 21. Among them, the hook plate 22 is provided with two pins 221, and the two lifting plates 23 are respectively connected to the two ends of the two pins 221, and the two lifting plates 23 are respectively located on the outer side of the width direction of the rotating seat 21.

[0072] Furthermore, a central shaft 211 is provided through the center of the rotating seat 21 in the width direction, and the rotating seat 21 is rotatably connected to the hook body 1 through the central shaft 211; two slide rods 212 are symmetrically arranged on both sides of the central shaft 211, and the slide seat 24 is slidably connected to the central shaft 211 and the two inner slide rods 212; two first compression springs 216 are respectively sleeved on the two outer slide rods 212; the blocking end 261 of the unlocking piece 26 is provided with a slot 2611 for hooking on the outer slide rod 212. By setting the central shaft 211 on the rotating seat 21, the rotating seat 21 can be rotatably connected to the hook body 1, and the rotating seat can rotate axially in a direction perpendicular to the first vertical plate and the second vertical plate, so that the adapter clamping mechanism 2 can adapt to the inclined angle steel of the tower end. The outermost slide bar 212 on the rotating seat 21 allows the first compression spring 216 to be sleeved on it, and the slot 2611 on the blocking end 261 of the unlocking piece 26 can be engaged on the outermost slide bar 212 to abut against the first compression spring 216.

[0073] Figure 8 The diagram shows the structure of the unlocking piece 26. As can be seen from the diagram, the blocking end 261 and the pressure end 262 of the unlocking piece 26 are connected at a certain angle to form a whole. The middle part of the unlocking piece 26 is provided with a through hole. The unlocking piece 26 is rotatably connected to the sliding seat 24 through the unlocking pin passing through the through hole.

[0074] See Figure 7 The sliding seat 24 has an I-shaped structure, including a first end plate and a second end plate arranged in parallel. The first end plate and the second end plate are connected by a connecting plate. The snap-fit ​​hole 241 is provided on the second end plate. Two unlocking pieces 26 are rotatably connected to both sides of the second end plate in the width direction by unlocking pins, and the two unlocking pieces 26 are symmetrically arranged. That is, the blocking ends 261 of the two unlocking pieces 26 can be locked onto the outer slide rod 212 of the rotating seat 21 through the slot 2611 and abut against the first compression spring 216. The pressure ends 262 of the two unlocking pieces 26 are located below the unlocking plate 27. The unlocking plate 27 is pulled downward by the steel wire rope 51. The unlocking plate 27 presses the pressure ends 262 of the unlocking pieces 26, causing the unlocking pieces 26 to rotate. As a result, the blocking ends 261 of the unlocking pieces 26 no longer abut against the first compression spring 216. The first compression spring 216 loses its force on the sliding seat 24, thereby eliminating the clamping force of the clamping plate 25 connected to the sliding seat 24 on the tower end angle steel, thus achieving unlocking. In this embodiment, two sliding sleeves 242 are symmetrically arranged on both sides of the connecting plate on the sliding seat 24. The two ends of the two sliding sleeves 242 are respectively connected to the first end plate and the second end plate. The two sliding rods 212 on the inner side of the rotating seat 21 pass through the two sliding sleeves 242 respectively. A moving block 243 is connected to the two sliding sleeves 242. A long through hole for the moving block 243 to pass through is opened on the bottom plate of the rotating seat 21. The clamping plate 25 is fixedly connected to the lower end of the moving block 243. In this embodiment, multiple clamping plates 25 are arranged in parallel. A guide plate 28 is fixedly connected to the two outermost clamping plates 25 respectively. The lower end of the guide plate 28 is inclined towards the first vertical plate 111 of the hook side plate 11, so as to realize the guiding function when it is hooked onto the pole end angle steel, making it easier for the adapter clamping mechanism 2 to be hooked onto the pole end angle steel. The bottom ends of the two guide plates 28 are connected by an isolation column 281, so that the two guide plates 28 are connected as one, forming a rigid structure and enhancing its structural strength.

[0075] The working principle of the adapter clamping mechanism 2 is as follows: Before attaching the pole end hook-up device, the adapter clamping mechanism 2 is first adjusted to the initialization state. Specifically: First, manually rotate the unlocking plate 26 so that the blocking end 261 of the unlocking plate 26 abuts against the first compression spring 216. Then, slide the sliding seat 24 to one side of the hook plate 22 until the hook at the second end of the hook plate 22 is engaged at the hook hole 241 of the sliding seat 24. At this time, the first compression spring 216 is in the stored state, completing the initialization setting of the adapter clamping mechanism 2. Figure 4 As shown in the diagram. When the drone carrying the pole end attachment device is attached to the pole end angle steel, when the lifting plate 23 touches the angle steel, it will cause the hook plate 22 to move upward. The locking hook at the second end of the hook plate 22 will disengage from the locking hole 241 of the sliding seat 24. After the sliding seat 24 loses the limiting effect of the hook plate 22, under the action of the elastic force of the first compression spring 216, the sliding seat 24 moves away from the hook plate 22, thereby causing the clamping plate 25 connected to the sliding seat 24 to move laterally. The clamping plate 25 works in conjunction with the hook body 1 to clamp and fix it to the pole end angle steel, completing the low-pressure end attachment point. Figure 5 As shown in the diagram. When the pole-end hanging and dismantling device is removed, the drone lifts the top linkage unlocking mechanism 3, which in turn pulls the steel wire rope 51. The steel wire rope 51 drives the unlocking plate 27 to move downward along the guide shaft 214, pressing the unlocking piece 26 to rotate. This causes the blocking end 261 of the unlocking piece 26 to no longer abut against the first compression spring 216, and the sliding seat 24 is no longer subjected to the force of the first compression spring 216. As a result, the clamping plate 25 connected to the sliding seat 24 loses its clamping force on the pole-end angle steel. The drone can then remove the pole-end hanging and dismantling device from the pole-end angle steel by raising the height.

[0076] See Figures 9 to 11The top linkage unlocking mechanism 3 includes: a top cover 31, a top moving block 32, a top lifting plate 33, top pins 34, a top lifting member 35, a top sliding rod 311, and a top moving cap 36; wherein, the bottom of the top cover 31 is provided with a top support 37, and the top cover 31 is connected to the top of the hook body 1 through the top support 37; the top sliding rod 311 is vertically arranged at the center of the top cover 31, and the top moving cap 36 is slidably connected to the top sliding rod 311, and the top moving cap 36 is provided with a steel wire rope 51 connected to the adapter clamping mechanism 2; two top pins 34 are slidably connected to the top plate of the top cover 31, and one end of the two top pins 34 located on the outside of the top plate of the top cover 31 is connected to the top lifting member 35. The top lifting member 35 is connected to a hook 38 for connecting with a drone. One end of each of the two top pins 34 located inside the top cover 31 is connected to one of the two top moving blocks 32. The top moving block 32 has a sloping groove 321 in the middle. The top lifting plate 33 is rotatably disposed in the sloping groove 321. The top lifting plate 33 includes a support section 331 and a pressing section 332 connected together. The pressing section 332 extends out of the outer side of the top cover 31. When the support section 331 is supported in the sloping groove 321, the end of the support section 331 can abut against the lower end of the top moving cap 36. When the pressing section 332 of the top lifting plate 33 is pressed down, the end of the support section 331 can rotate to the top of the top moving cap 36.

[0077] Specifically, such as Figure 10 As shown, the top lifting component 35 includes a vertical bushing for connecting the hook 38 and a horizontal rod connected to the vertical bushing. The upper ends of two top pins 34 are respectively connected to the two ends of the horizontal rod, and the lower ends of the two top pins 34 are respectively connected to two symmetrically arranged top moving blocks 32 inside the top cover 31. The inclined groove 321 on the top moving block 32 is located in the middle position of the top moving block 32. To enable the top pins 34 to connect to the middle position of the top moving block 32, a top moving block cover plate 322 is fixed on the top of the top moving block 32, and the lower ends of the top pins 34 are connected to the top moving block cover plate 322. To make the top moving blocks 32 more stable when moving up and down, each top moving block 32 is slidably connected to two top guide rods 312. The top guide rods 312 are fixedly connected between the top plate and the bottom plate of the top cover 31, as shown. Figure 11 As shown, there are four top guide rods 312, and each top moving block 32 is slidably connected to two top guide rods 312 respectively.

[0078] Furthermore, a limiting block 362 for height limiting of the top movable cap 36 is fixed on the top slide rod 311. The limiting block 362 has a ring structure and is sleeved on the top slide rod 311. The limiting block 362 can be fixedly connected to the top slide rod 311 by a set screw. The limiting height of the top movable cap 362 is such that when the top movable block 32 is located at the bottom plate of the top cover 31, the top lifting plate 33 on the top movable block 32 is located below the top movable cap 36. When the pressing section 332 of the top lifting plate 33 is pressed, the end of the supporting section 331 of the top lifting plate 33 can rotate to the outside of the top movable cap 36. In this embodiment, a linear bearing is provided between the top movable cap 36 and the top slide rod 311, and a top movable cap cover plate 361 for fixing the linear bearing is provided on the top of the top movable cap 36.

[0079] The top support 37 has a groove-shaped structure and can be fixedly connected to the two hook side plates 11 of the hook body 1 via the two groove side plates of the groove-shaped structure. The top support 37 is provided with a grooved wheel 52 for guiding the wire rope 51. Below the grooved wheel 52, there is a limiting pin 371 for preventing the wire rope 51 from coming off. The limiting pin 371 is connected to the two hook side plates 11 of the hook body 1.

[0080] See Figure 2 In this embodiment, two steel wire ropes 51 are connected to the top movable cap 36, and two grooved wheels 52 are provided on the top support 37. The two grooved wheels 52 are located on the left and right sides of the top slide bar 311, respectively. Two grooved wheels 52 are also provided at the positions of the first vertical plate 111 and the second vertical plate 112 of the hook side plate 11. After the two steel wire ropes 51 connected to the top movable cap 36 pass through the bottom plate of the top cover 31 and the top support 37, they pass sequentially from the left and right directions, around the grooved wheels 52 on the top support 37, the two grooved wheels 52 on the hook body 1, and the grooved wheels 52 on the rotating seat 21 of the adapter clamping mechanism 2, and then connect to the end of the unlocking plate 27. By setting two steel wire ropes 51 to pull the two ends of the unlocking plate 27 at the same time, the unlocking plate 27 can be better stressed and the unlocking piece 26 can be pressed more reliably to achieve unlocking.

[0081] The working principle of the top linkage unlocking mechanism 3 is as follows: Before attaching the pole end attachment device, the top linkage unlocking mechanism 3 is first adjusted to the initialization state. Specifically, by manually pressing the pressing section 332 of the two top lifting plates 33, the end of the support section 331 of the top lifting plate 33 is moved to the outside of the top moving cap 36. Then, the top lifting component 35 is lifted, which drives the top moving block 32 to move upward, so that the top lifting plate 33 moves above the top moving cap 36. After that, the top lifting plate 33 is released, and at the same time, the top lifting component 35 is connected to the drone through the hook. After the drone carrying the pole end hook-and-unhook device is attached to the pole end angle steel and the angle steel is clamped, the drone is controlled to detach from the hook. Under the action of gravity, the top lifting component 35, the top pin 34, and the top moving block 32 move downward. During the downward movement, when the top lifting plate 33 on the top moving block 32 touches the top moving cap 36, the top lifting plate 33 rotates and the top moving block 32 continues to move downward. When the top lifting plate 33 moves completely below the top moving cap 36, the top lifting plate 33 resets under its own weight. When the pole end hanging and dismantling device is removed, the drone lifts the top lifting component 35 through the hook, which drives the top moving block 32 to move upward. The top lifting plate 33 on the top moving block 32 will drive the top moving cap 36 to move upward along the top sliding rod 311, thereby pulling the steel wire rope 51 connected to the top moving cap 36. In turn, the steel wire rope 51 pulls the unlocking plate 27 in the clamping mechanism 2 to move downward. The unlocking plate 27 presses down to rotate the unlocking piece 26. The unlocking piece 26 separates from the first compression spring 216, the spring returns to its original state, and the clamping force on the clamping plate 25 is released, thereby unlocking the angle steel.

[0082] See Figure 12The second grounding locking mechanism 4 includes: a locking cylinder 41, a locking assembly, a grounding connector 45, and a traction rope 46; wherein, the top of the locking cylinder 41 has a through hole for the traction rope 46 to pass through; at least two locking assemblies are evenly distributed circumferentially on the locking cylinder 41; each locking assembly includes a locking block 42, an elastic element 44, and a locking pin 43, the locking block 42 has a transverse sliding hole, the elastic element 44 is disposed in the sliding hole, the locking pin 43 is slidably disposed in the sliding hole and connected to the elastic element 44, and one end of the locking pin 43 extending out of the sliding hole has a downwardly inclined wedge-shaped surface; the grounding connector 45... The upper end is connected to the traction rope 46, and the lower end of the ground wire clamp 45 is connected to the ground wire. The ground wire clamp 45 includes an upper conical head 451, a middle clamping shaft 452, and a lower connecting body 453. The diameter of the larger end of the conical head 451 is larger than the diameter of the clamping shaft 452. The upper end of the connecting body 453 is provided with a blocking ring 4531 with a diameter larger than that of the clamping shaft 452. An unlocking ring 454 is slidably provided on the clamping shaft 452. The upper diameter of the unlocking ring 454 is equal to the diameter of the larger end of the conical head 451, and the lower diameter of the unlocking ring 454 is equal to the diameter of the clamping shaft 452.

[0083] Specifically, the locking cylinder 41 is fixedly connected to the lower end of the hook body 1. The center of the locking cylinder 41 is a receiving cavity for accommodating the ground wire clamp connector 45. The locking block 42 of the locking assembly is fixedly connected to the lower opening of the receiving cavity of the locking cylinder 41. Two guide groove wheels 461 for guiding the traction rope 46 are rotatably arranged on the hook body 1 above the locking cylinder 41. A retaining edge 14 is also provided on the outside of the guide groove wheels 461 on the hook body 1 to prevent the traction rope from slipping off. The traction rope 46 connected to the ground wire clamp connector 45 passes through the through hole at the top of the locking cylinder 41, goes around the two guide groove wheels 461, exits the outside of the hook body 1, and extends downwards for ground personnel to pull, thereby completing the engagement of the ground wire clamp connector 45 with the locking assembly and completing the connection of the grounding wire at the tower end. In this embodiment, three locking assemblies are provided, evenly distributed along the circumference of the locking cylinder 41, i.e., adjacent locking assemblies are spaced 120° apart. The elastic element 44 in the sliding hole of the locking block 42 is a compression spring. The sliding hole of the locking block 42 is a stepped hole to prevent the compression spring from coming out of the outside of the sliding hole. The locking pin 43 is a stepped shaft. The two ends of the compression spring abut against the stepped surfaces of the sliding hole and the locking pin 43, respectively. The end of the locking pin 43 located in the sliding hole can be screwed with a bolt to limit its position and prevent the locking pin 43 from coming out of the sliding hole. The end of the locking pin 43 extending out of the sliding hole is provided with a downwardly inclined wedge-shaped surface. When the ground wire connector 45 touches the wedge-shaped surface of the locking pin 43, it pushes the locking pin 43 to retract into the sliding hole and compress the compression spring in the sliding hole. When the contact part between the locking pin 43 and the ground wire connector 45 moves from the conical head 451 to the locking shaft 452, the diameter of the ground wire connector 45 suddenly decreases. Under the action of the compression spring, the locking pin 43 extends and abuts against the locking shaft 452, thus completing the locking of the ground wire connector 45. When it is necessary to unlock the ground wire clamp 45, the unlocking ring 454, which is slidably set on the clamping shaft 452, is used to pull the ground wire clamp 45 upward by the traction rope 46. This causes the wedge-shaped surface of the locking pin 43 to contact the unlocking ring 454 at the lower end of the clamping shaft 452. The locking pin 43 is pushed into the sliding hole and retracts, compressing the compression spring in the sliding hole. The unlocking ring 454 is an inverted conical structure with a larger diameter at the upper end and a smaller diameter at the lower end. When the top of the locking pin 43 slides to the conical surface of the unlocking ring 454, it will be pushed out of the sliding hole by the compression spring and along the unlocking ring 454. The conical surface of ring 454 slides onto the locking shaft 452 at the lower end of the unlocking ring 454. At this time, the traction rope 46 is released. Under the gravity of the grounding wire and the grounding connector 45, the locking pin 43 pushes the unlocking ring 454 to the upper end of the locking shaft 452. Then the locking pin 43 will slide along the conical surface of the unlocking ring 454. Since the diameter of the upper end of the unlocking ring 454 is equal to the diameter of the large end of the conical head 451, after the locking pin 43 slides to the upper end of the unlocking ring 454, it will then move onto the conical head 451. The grounding connector 45 continues to fall, completing the unlocking of the grounding connector 45.In this embodiment, the locking cylinder 41 is also provided with a guide sleeve, which includes a cylindrical section inserted into the receiving cavity of the locking cylinder 41 and a conical section located outside the receiving cavity. The conical section can guide the ground wire clamp connector 45 so that it can enter the receiving cavity of the locking cylinder 41 more easily.

[0084] See Figure 13 The wire clamping mechanism 6 includes a hook body 61, a telescopic fixing sleeve 62, a hook bracket 63, a vertical movable block 64, and two clamping contact blocks 65. The hook body 61 has a hook-shaped structure. The telescopic fixing sleeve 62 is fixedly connected to the top of the hook body 61. The hook bracket 63 is used to connect with a drone, and a hanging column 631 is fixedly connected to the lower end of the hook bracket 63. The hanging column 631 is partially slidably disposed within the telescopic fixing sleeve 62, and its lower end extends below the telescopic fixing sleeve 62. A vertical movable block 64 is fixedly connected to the lower end of the hanging column 631, and two vertically downward extending locking plates are provided on the vertical movable block 64. The vertical movable block 64 and the telescopic fixing sleeve 62 are connected to the hook body 61. A return spring 66 is fitted on the hanging column 631 between the retractable fixing sleeves 62; two clamping contact blocks 65 are rotatably connected to the hook body 61, and the two clamping contact blocks 65 are respectively located on the lower sides of the vertical movable block 64. The hook body 61 is provided with limiting pins 611 that limit the rotation angle of the two clamping contact blocks 65 respectively; one end of the two clamping contact blocks 65 facing each other is provided with an arc-shaped groove for clamping the wire, and a telescopic supplement block 651 is provided in the arc-shaped groove; the top of the two clamping contact blocks 65 is provided with a snap-fit ​​groove for snapping with the two snap-fit ​​plates on the vertical movable block 64; the first ground wire locking mechanism is connected to the lower end of the hook body 61.

[0085] Specifically, the hook body 61 has a downward-opening hook-shaped structure and includes two spaced-apart side plates, which are fixedly connected together by a connecting plate (not shown in the figure). A burr is provided at the top of the opening of the hook body 61 to increase the contact area with the wire; copper sheets are provided on the inner side of the side plates of the hook body 61 to guide the current on the wire to the first grounding locking mechanism and ultimately to the grounding wire. A guide baffle 67 is also provided on one side of the opening of the hook body 61, with its lower end inclined outwards. The guide baffle 67 guides the wire during hooking. The lower end of the telescopic fixing sleeve 62 can be fixedly connected to the two side plates of the hook body 61 by welding or screws. The top of the hook bracket 63 is equipped with multiple hook-like structures for hooking onto the drone. The main body of the hook bracket 63 is a hollow tubular structure. The upper section of the hanging column 631 is inserted into the lower end of the hook bracket 63 and fixedly connected to it. The diameter of the lower middle section of the hanging column 631 is smaller than that of its upper section, and the lower middle section of the hanging column 631 is slidably disposed in the telescopic fixing sleeve 62. A linear bearing is provided in the telescopic fixing sleeve 62 to reduce the frictional resistance when the hanging column 631 slides up and down in the telescopic fixing sleeve 62. The top of the telescopic fixing sleeve 62 is equipped with a hanging column cap 621 to fix the linear bearing and prevent the hanging column 631 from shifting position due to rotation. The clamping contact block 65 has a stepped hole in its arc-shaped groove. The telescopic supplement block 651 is cylindrical and slidably connected to the stepped hole. A supplement block spring 652, a helical compression spring, is installed in the stepped hole. A baffle is provided at one end of the telescopic supplement block 651 in the arc-shaped groove. The other end of the telescopic supplement block 651 can be prevented from dislodging from the stepped hole by a screw or a retaining ring structure. The two ends of the supplement block spring 652 abut against the stepped surface of the stepped hole and the baffle of the telescopic supplement block 651, respectively. The supplement block spring 652 provides elastic force to the telescopic supplement block 651, which is used to fill the gap between wires and adapt to wires of different sizes.

[0086] The working principle of the wire clamping mechanism 6 is as follows: The drone, equipped with a wire end attachment / removal device mounted on the hook bracket 63 at the top of the wire clamping mechanism 6, moves to a position above the wire to be attached. The drone is then slowly lowered to attach the wire clamping mechanism 6 to the wire. Under the weight of the wire end attachment / removal device, the two clamping contact blocks 65 in contact with the wire rotate. As the clamping contact blocks 65 rotate, their upper ends push the vertical movable block 64 upward until the locking groove at the top of the clamping contact block 65 aligns with the locking plate on the vertical movable block 64. Then, under the action of the return spring 66, the vertical movable block 64 moves rapidly downward, causing the locking plate of the vertical movable block 64 to engage with the locking groove of the clamping contact block 65. The two clamping contact blocks 65 lock and clamp the wire. If the wire end attachment / removal device cannot automatically clamp the wire using the clamping contact block 65 due to its own weight, the traction rope 46 on the first ground wire locking mechanism can be pulled from the ground. Under the pulling force, the two clamping contact blocks 65 rotate until the locking groove engages with the locking plate of the vertical movable block 64, locking and clamping the wire. The telescopic supplementary block 651 on the clamping contact block 65 can automatically extend and retract according to the wire size to further compress the wire. When the wire end attachment / removal device needs to be removed after the operation is completed, the hook bracket 63 of the wire clamping mechanism 6 is lifted by a drone, causing the vertical movable block 64 to move upward. The two clamping contact blocks 65 separate from the vertical movable block 64, and the two clamping contact blocks 65 rotate and release the wire, completing the unlocking.

[0087] The first ground wire locking mechanism and the second ground wire locking mechanism 4 have the same structure, and the structure of the second ground wire locking mechanism 4 described above can be found in the details.

[0088] The present invention also provides a method for attaching and removing a grounding wire, which is implemented using the grounding wire attachment and removal device described above, and includes the following steps:

[0089] The pole end attachment process involves attaching the pole end attachment device to the drone, which then flies to the angle steel of the pole to be attached by carrying the device. The drone lowers its flight altitude to clamp the adapter clamping mechanism 2 in the pole end attachment device onto the angle steel of the pole.

[0090] Specifically, first adjust the adapter clamping mechanism 2 and the top linkage unlocking mechanism 3 to the initialization state, including rotating and moving the top lifting plate 33 in the top linkage unlocking mechanism 3 above the top moving cap 36, rotating the unlocking piece 26 in the adapter clamping mechanism 2 so that the blocking end 261 of the unlocking piece 26 abuts against the first compression spring 216, and moving the sliding seat 24 so that the sliding seat 24 engages with the hook plate 22, so that the first compression spring 216 is compressed into a stored state.

[0091] The drone, equipped with the pole-end attachment / removal device, moves to a position above the angle steel at the pole end. The drone then descends slowly. As the lifting plate 23 in the clamping mechanism 2 presses against the angle steel, it causes the hook plate 22 to separate from the sliding seat 24. Under the elastic force of the first compression spring 216, the sliding seat 24 moves away from the hook plate 22, thereby clamping the angle steel with the clamping plate 25 fixedly connected to the sliding seat 24. After the drone separates from the pole-end attachment / removal device, the top moving block 32 in the top linkage unlocking mechanism 3 moves to its lowest position under gravity, and the top lifting plate 33 on the top moving block 32 moves below the top moving cap 36.

[0092] In the wire end splicing step, the wire end splicing device is attached to the drone. The drone carries the wire end splicing device and flies to a position above the wire to be spliced. The drone lowers its flight altitude to clamp the wire clamping mechanism 6 in the wire end splicing device onto the wire.

[0093] Specifically, the drone, equipped with a wire end attachment / removal device mounted on the hook bracket 63 at the top of the wire clamping mechanism 6, moves to above the wire to be attached. The drone then slowly descends, attaching the wire clamping mechanism 6 to the wire. Under the weight of the wire end attachment / removal device, the two clamping contact blocks 65 in contact with the wire rotate. As the clamping contact blocks 65 rotate, their upper ends push the vertical movable block 64 upward until the locking groove at the top of the clamping contact block 65 aligns with the locking plate on the vertical movable block 64. At this point, the vertical movable block 64 moves rapidly downward under the action of the return spring 66, causing the locking plate of the vertical movable block 64 to engage with the locking groove of the clamping contact block 65. The two clamping contact blocks 65 then lock and clamp the wire. If the wire end hanging and unhooking device itself cannot achieve automatic clamping of the wire by the clamping contact block 65, the traction rope 46 on the first ground wire locking mechanism can be pulled on the ground. Under the action of the pulling force, the two clamping contact blocks 65 rotate until the locking groove is engaged with the locking plate of the vertical movable block 64, locking and clamping the wire.

[0094] The grounding wire locking step involves sequentially connecting and locking the low-voltage end and high-voltage end of the grounding wire through the second grounding wire locking mechanism 4 and the first grounding wire locking mechanism, before proceeding with the work on the wire to be attached.

[0095] Specifically, by pulling the traction rope 46 of the second ground wire locking mechanism 4 and the traction rope 46 of the first ground wire locking mechanism in sequence, the ground wire clamp 45 connected to the low-voltage end and the high-voltage end of the ground wire is respectively clamped to the locking components of the second ground wire locking mechanism 4 and the first ground wire locking mechanism, thus completing the connection of the ground wire at the tower end (low-voltage hanging point) and the conductor end (high-voltage hanging point).

[0096] After the grounding wire removal procedure is completed, the high-voltage end and low-voltage end of the grounding wire are unlocked by the first grounding wire locking mechanism and the second grounding wire locking mechanism 4 respectively, and the grounding wire is moved to the ground and removed.

[0097] Specifically, pulling the traction rope 46 of the first ground wire locking mechanism causes the ground wire clamp 45, connected to the high-voltage end of the ground wire, to continue moving upwards. This causes the wedge-shaped surface of the locking pin 43 to contact the unlocking ring 454 at the lower end of the locking shaft 452. The locking pin 43 is pushed into the sliding hole, compressing the compression spring within. The unlocking ring 454 is an inverted conical structure with a larger diameter at the top and a smaller diameter at the bottom. When the top of the locking pin 43 slides to the conical surface of the unlocking ring 454, it will be pushed out of the sliding hole by the compression spring and slide along the conical surface of the unlocking ring 454. On the locking shaft 452 at the lower end of the unlocking ring 454, the traction rope 46 is released. Under the gravity of the grounding wire and the grounding wire locking connector 45, the locking pin 43 pushes the unlocking ring 454 to the upper end of the locking shaft 452. Then the locking pin 43 will slide along the conical surface of the unlocking ring 454. Since the upper diameter of the unlocking ring 454 is equal to the diameter of the large end of the conical head 451, after the locking pin 43 slides to the upper end of the unlocking ring 454, it will then move to the conical head 451. The grounding wire locking connector 45 continues to fall, completing the unlocking of the grounding wire high-voltage end grounding wire locking connector 45.

[0098] The steps for unlocking the low-voltage end of the grounding wire using the second grounding locking mechanism 4 are the same as those for unlocking the high-voltage end of the grounding wire using the first grounding locking mechanism described above.

[0099] The wire end removal step involves using a drone to lift the wire end removal device, thereby unlocking the wire clamping mechanism 6 in the device and separating it from the wire. The drone then carries the wire end removal device to the ground.

[0100] Specifically, by using the drone to lift the hook bracket 63 of the wire clamping mechanism 6, the vertical movable block 64 moves upward, the two clamping contact blocks 65 separate from the vertical movable block 64, the two clamping contact blocks 65 rotate and release the wire, thus completing the unlocking.

[0101] The pole-end dismantling process involves using a drone to lift the top linkage unlocking mechanism 3 in the pole-end dismantling device, thereby unlocking and separating the adapter clamping mechanism 2 in the pole-end dismantling device from the angle steel of the pole. The drone then carries the pole-end dismantling device to the ground.

[0102] Specifically, the drone lifts the top lifting member 35 of the top linkage unlocking mechanism 3 upward by hooking it up, which drives the top moving block 32 upward. The top lifting plate 33 on the top moving block 32 lifts the top moving cap 36 on the top sliding rod 311 upward, which in turn pulls the steel wire rope 51 connected to the top moving cap 36. This causes the steel wire rope 51 to pull the unlocking plate 27 downward along the guide shaft 214. The unlocking plate 27 presses down on the unlocking piece 26 to rotate, so that the blocking end 261 of the unlocking piece 26 no longer abuts against the first compression spring 216. The sliding seat 24 is no longer subjected to the force of the first compression spring 216, so that the clamping plate 25 connected to the sliding seat 24 loses the clamping force on the pole end angle steel, thereby unlocking the angle steel. The drone can remove the pole end hook-and-unhook device from the pole end angle steel by raising the height.

[0103] The grounding wire hanging and dismantling device and method provided by the present invention include a conductor end hanging and dismantling device and a tower end hanging and dismantling device. The tower end hanging and dismantling device and the conductor end hanging and dismantling device can be carried by a drone to sequentially complete the hanging of the low-voltage end hanging point and the high-voltage end hanging point. The adaptive clamping mechanism of the tower end hanging and dismantling device and the conductor clamping mechanism of the conductor end hanging and dismantling device can respectively realize adaptive clamping and reliable contact of the tower end angle steel and the conductor, effectively avoiding the risk of intermittent disconnection of the grounding wire.
