Description

Technical Field

[0001] The present invention relates to the technical field of power transmission line maintenance devices, in particular to a tool for hanging and removing ground wires of power transmission line towers by unmanned aerial vehicles. Background Art

[0002] Before a power outage for maintenance, a grounding wire must be installed on the ground conductor to prevent injuries from induced voltage and to avoid damage to maintenance personnel due to erroneous power transmission from the line or equipment during the operation. After the line maintenance work is completed, the grounding wire must be removed before power can be restored. Currently, the installation and removal of grounding wires for transmission lines are still carried out by traditional manual tower climbing. Workers must wear shielding clothing and carry heavy grounding wires on their backs to climb the tower. After reaching the crossarm of the tower, they must install grounding wire clamps from the conductor end to the ground end in accordance with safety regulations, and complete the installation of the three-phase conductors phase by phase. This operation is time-consuming and intensive, requiring high physical fitness from maintenance personnel. The installation is difficult, and there is a risk of falling from heights and the danger of induced electrical contact, posing a significant safety hazard. Summary of the Invention

A movable wire flip clamping plate, a rotatable angle steel flip clamping plate is hingedly installed at one side of the opening in the N-type clamp body of the angle steel end clamp, and a first baffle and a second baffle are provided on the wire flip clamping plate and the angle steel flip clamping plate. A pull rod is provided on the plate body of the flip clamping plate, and a tension spring is installed between the pull rod and the N-type clamp body. An arc-shaped limit groove matching the pull rod is provided on the N-type clamp body. When the pull rod is located at one end in the arc-shaped limit groove, the first baffle is located at the opening position of the N-type clamp body, and the second baffle is located in the N-type clamp body. When the pull rod is located at the other end in the arc-shaped limit groove, the first baffle is located in the N-type clamp body, and the second baffle is located at the opening position of the N-type clamp body. The drone is connected to a connecting rod frame via a thrower mechanism. The thrower mechanism includes a mounting frame, on which a power supply and a controller are mounted. Two sets of connecting and disassembling devices are mounted at the bottom of the mounting frame. Each connecting and disassembling device includes a connecting frame, on which a drive motor is mounted. A rocker arm is provided on the output shaft of the drive motor. A latch is connected to the end of the rocker arm. A through hole is provided on the connecting frame to cooperate with the latch. A hanging ring is also installed on the connecting rod frame to allow the latch to pass through. When the drive motor is activated, the latch can be driven in and out of the hanging ring to realize the assembly and disassembly of the thrower mechanism and the connecting rod frame. The connecting rod frame includes a first horizontally arranged crossbar, with hanging chains mounted at both ends of the first crossbar in the longitudinal direction. A second crossbar is arranged at the bottom of the hanging chain. A long hanging rod and a short hanging rod are connected to the two ends of the second crossbar in the longitudinal direction, respectively. Hanging rings are mounted at the bottom of the long hanging rod and the short hanging rod. The N-shaped clamp body is mounted with a guide sleeve that mates with the vertical pole. The vertical pole can be raised and lowered vertically along the guide sleeve. The end of the vertical pole that extends downward from the guide sleeve is connected to a take-up rope. A reel is located within the N-shaped clamp body, and the take-up rope is wound around the reel. A first torsion spring is mounted on the reel's rotating shaft. This first torsion spring constantly tends to cause the reel to pull the take-up rope back, thereby moving the vertical pole downward. A vertical guide slot is defined on the side of the vertical pole that extends into the N-shaped clamp body. A vertical guide rod is mounted within the N-shaped clamp body, which mates with the vertical guide slot.The N-type clamp body is equipped with a tension spring tension adjustment device.

An adjustment bolt is mounted between the fastening bolt and the adjustment plate, with the end of the adjusting bolt's screw contacting the fastening bolt. A connecting rod connected to the tension spring is also mounted on the adjustment plate. Rotating the adjustment bolt adjusts the initial length and tension of the tension spring between the connecting rod and the pull rod. A protective shield is mounted on the fastening bolt, with a clearance slot defined in the shield that mates with the arc-shaped limit slot. The pull rod extends through the clearance slot. The protective shield also includes a clearance hole that mates with the adjustment bolt and the connecting rod. An auxiliary bracket is mounted on the N-type clamp body. The auxiliary bracket is equipped with a camera and a GPS module. The camera can monitor the rotational position of the wire flip clamp plate and the angle steel flip clamp plate. The bottom of the N-shaped clamp body is equipped with flaring guide plates at both ends. A rotatable anti-drop plate is installed at the end of the opening in the N-shaped clamp body. The anti-drop plate is fixed to the N-shaped clamp body via a rotating shaft. A second torsion spring is installed on the rotating shaft, which always tends to rotate the anti-drop plate to block the opening of the N-shaped clamp body.

[0005] The present invention provides the following positive effects: The drone-mounted tool for hanging and removing ground wires from transmission line towers utilizes a drone-driven connecting rod frame to achieve aerial hoisting of the conductor end clamp and angle steel end clamp. The clamps are securely attached to the conductor and angle steel under test using a flip-up clamping plate within the clamps. The drone-mounted tool enables contactless operation, completely eliminating the risk of falls and electric shock associated with manual tower climbing. Operators can remotely control the tool from the ground, avoiding direct exposure to high-voltage electric fields and the harsh tower environment. This fundamentally safeguards personnel safety and aligns with the trend of "reduced-manpower, unmanned" operation and maintenance for smart grids. The drone can quickly traverse complex terrain to reach the work site, making it particularly suitable for specialized tower locations such as mountainous areas and those across rivers. This significantly improves operational efficiency and safety. This approach transforms traditional manual ground wire hanging and removal methods, unaffected by terrain or tower shape. The operation is convenient and efficient, reducing maintenance time and labor intensity, and ensuring personal safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The invention relates to a drone-mounted tool for mounting and removing a grounding wire from a transmission line tower. Figure 1 and Figure 2 As shown, it includes a drone 1, a detachable connecting rod frame 2 is installed on the drone 1, and two groups of hanging rings 3 are connected to the bottom end of the connecting rod frame 2, one group of hanging rings 3 is hung with a detachable wire end clamp, and the other group of hanging rings 3 is hung with a detachable angle steel end clamp, and a grounding wire 4 is connected between the wire end clamp and the angle steel end clamp.

[0019] Drone 1 can be a multi-rotor drone with a payload greater than 10 kg, offering stable hovering and flexible control. Drone 1 is used to lift the entire system to a designated high-altitude location. The grounding wire 4, connected between the conductor end fixture and the angle steel end fixture, can be a soft copper wire with a transparent sheath corresponding to different voltage levels. The length of grounding wire 4 can be adaptively selected based on the voltage level and insulator string length, with a cross-section of 25 square millimeters, as required by safety regulations. The conductor end fixture is fixed to a sub-conductor, and the angle steel end fixture is fixed to the crossarm tower material. Operators control the drone to perform aerial installation and removal of the entire grounding wire system.

[0020] like Figure 3-6As shown, both the conductor and angle steel end clamps include an N-shaped clamp body 5, the lower opening of which is used to clamp onto the crossarm tower material or conductor for secure mounting. A vertically arranged upright pole 6 is mounted on the N-shaped clamp body 5, and a barb 7 is provided at the top of the upright pole 6 for hooking with the hanging ring 3. Under the action of gravity, the barb 7 can hang the lower clamp together with the hanging ring 3 at the bottom of the drone 1. The coordination between the barb 7 and the hanging ring 3 allows the drone to be controlled and mounted.

[0021] In order to respectively realize the clamping and fixing of the cross-arm tower material or the conductor, a rotatable conductor flip clamping plate 8 is hingedly installed at one side of the opening in the N-type clamp body 5 of the conductor end clamp, and a rotatable angle steel flip clamping plate 9 is hingedly installed at one side of the opening in the N-type clamp body 5 of the angle steel end clamp. Due to the different clamping structures, the conductor flip clamping plate 8 and the angle steel flip clamping plate 9 can adaptively clamp and fix the conductor and the cross-arm tower material respectively.

[0022] The wire flip clamping plate 8 and the angle steel flip clamping plate 9 are both provided with a first baffle 10 and a second baffle 11. A space is left between the first baffle 10 and the second baffle 11 for placing cross-arm tower materials or wires. A pull rod 12 is provided on the plate body of the flip clamping plate. A tension spring 13 is installed between the pull rod 12 and the N-type clamping body 5. An arc-shaped limit groove 14 that matches the pull rod 12 is opened on the N-type clamping body 5. The tension spring 13 always has a tendency to pull the pull rod 12 into the two end positions of the arc-shaped limit groove 14. When the pull rod 12 is located at the end position of the arc-shaped limit groove 14, the flip clamping plate will no longer rotate without being affected by external force.

[0023] When the pull rod 12 is located at one end in the arc-shaped limit groove 14, the first baffle 10 is located at the opening position of the N-type clamp body 5, and the second baffle 11 is located in the N-type clamp body 5. When the pull rod 12 is located at the other end in the arc-shaped limit groove 14, the first baffle 10 is located in the N-type clamp body 5, and the second baffle 11 is located at the opening position of the N-type clamp body 5.

[0024] by Figure 3 Taking the middle wire end clamp as an example, the first baffle 10 is located at the upper side of the second baffle 11. When the wire end clamp has not yet been hung on the wire, the pull rod 12 is located at the lower end of the arc-shaped limit groove 14. The first baffle 10 is located at the opening position of the N-type clamp body 5, and the second baffle 11 is located inside the N-type clamp body 5. As the wire end clamp is lowered, the wire enters the opening and contacts the first baffle 10. Under the action of the gravity of the clamp, the first baffle 10 overcomes the elastic force of the tension spring 13 and rotates clockwise until the pull rod 12 moves to the upper end position of the arc-shaped limit groove 14 and stops rotating, and maintains this state. The second baffle 11 rotates from the N-type clamp body 5 to the opening position, and clamps the wire on the top wall of the opening position of the N-type clamp body 5.

[0025] The angle steel flip clamping plate 9 in the angle steel end clamp has the same action as the conductor end clamp. When the clamp is lowered onto the cross-arm tower material, the first baffle 10 of the angle steel flip clamping plate 9 will be pushed into the interior of the clamp, and the second baffle 11 will press the cross-arm tower material against the top wall of the opening position of the N-shaped clamp body 5.

[0026] Furthermore, in order to enable the drone 1 to be unhooked from the grounding device at the bottom in an emergency, the drone 1 can be connected to the connecting rod frame 2 through a thrower mechanism, and the thrower mechanism can be disassembled and assembled with the connecting rod frame 2, such as Figure 7 As shown, the thrower mechanism includes a mounting frame 15, which can be mounted on the bottom of the drone 1. A power supply 16 and a controller 17 are installed on the mounting frame 15. Two sets of connecting and disassembling devices are installed at the bottom of the mounting frame 15, and the connection and disassembly with the connecting rod frame 2 are realized through the connecting and disassembly devices.

[0027] Each connecting and disassembling device includes a connecting frame 18, on which is mounted a drive motor 19. A rocker 20 is mounted on the output shaft of the drive motor 19. A latch 21 is connected to the end of the rocker 20. A through-hole is formed in the connecting frame 18 that mates with the latch 21. A loop 22 is also mounted on the connecting rod frame 2, through which the latch 21 passes. When the drive motor 19 is activated, the latch 21 moves in and out of the loop 22, enabling assembly and disassembly of the thrower mechanism from the connecting rod frame 2.

[0028] Furthermore, in order to improve the strength of the overall structure of the connecting rod frame 2, as Figure 8 As shown, the connecting rod frame 2 may include a horizontally arranged first crossbar 23, with hanging chains 24 mounted at both ends of the first crossbar 23 in the longitudinal direction. A second crossbar 25 is disposed at the bottom of the hanging chain 24. A long hanging rod 26 and a short hanging rod 27 are connected to both ends of the second crossbar 25 in the longitudinal direction, respectively. The bottoms of the long hanging rod 26 and the short hanging rod 27 are both mounted with hanging rings 3. The arrangement of the long hanging rod 26 and the short hanging rod 27 allows the two sets of hanging rings 3 to be arranged one above the other, avoiding interference between the hanging rings 3 at the same height, thereby enabling the hanging operations of the wire end clamp and the angle steel end clamp on the wire and the crossarm tower material.

[0029] Furthermore, in order to hang the fixture at the designated position and after the drone 1 drives away, the exposed vertical pole 6 on the fixture can be retracted inward to reduce the size of the fixture at the hanging position and avoid excessive interference with the detection route, such as Figure 9 and Figure 10As shown, the N-type clamp body 5 can be mounted with a guide sleeve 28 that cooperates with the vertical rod 6, allowing the vertical rod 6 to be raised and lowered vertically along the guide sleeve 28. One end of the vertical rod 6 extending downward from the guide sleeve 28 is connected to a tightening rope 29. A reel 30 is provided within the N-type clamp body 5, and the tightening rope 29 is wound around the reel 30. A first torsion spring 46 is provided on the rotating shaft of the reel 30. The first torsion spring 46 always tends to cause the reel 30 to pull the tightening rope 29 back and move the vertical rod 6 downward.

[0030] Before the clamp is lifted by the drone 1, due to the setting of the drum 30, the lower end of the vertical pole 6 will enter the clamp. After being lifted by the drone 1, the vertical pole 6 will overcome the elastic force of the first torsion spring 46 under the action of its own gravity, allowing the vertical pole 6 to extend outward, increasing the distance between the drone 1 and the clamp mounted at the bottom, thereby facilitating the hanging operation of the clamp on the conductor or cross-arm tower material. After the hanging is completed, the drone 1 drives away, and the vertical pole 6 enters the inside of the clamp to a certain length under the action of the drum 30, reducing the volume of the entire clamp at the hanging position to avoid interference with the line.

[0031] Furthermore, in order to realize the directional lifting and lowering movement of the vertical pole 6 in the guide sleeve 28, a vertical guide groove 31 can be opened on the side of the vertical pole 6 extending into the N-type clamp body 5, and a vertical guide rod 32 that cooperates with the vertical guide groove 31 is installed in the N-type clamp body 5. The vertical guide rod 32 limits the vertical guide groove 31, so that the directional vertical lifting and lowering of the vertical pole 6 can be realized, avoiding the occurrence of deflection and the like during the vertical movement process, thereby extending the service life of the device.

[0032] Furthermore, in order to be able to adjust the initial pre-tensioning force of the tension spring 13 on the conductor flip clamping plate 8 and the angle steel flip clamping plate 9, so that the flip clamping plate can firmly clamp the conductor or cross-arm tower material, a tension spring tension adjustment device can be installed on the N-type clamp body 5, such as Figure 11 As shown, the tension spring tightness adjustment device includes an adjustment plate 33 arranged on the N-type clamp body 5, and a long groove 34 is opened on the adjustment plate 33. A matching fastening bolt 35 is installed between the N-type clamp body 5 and the long groove 34. The fastening bolt 35 passes through the end of the long groove 34 and is matched with a nut. After loosening the nut, the long groove 34 can move along the fastening bolt 35, thereby realizing the adjustment of the installation position of the adjustment plate 33 on the N-type clamp body 5.

[0033] An adjusting bolt 36 is installed between the fastening bolt 35 and the adjusting plate 33. The end of the screw of the adjusting bolt 36 contacts the fastening bolt 35. The adjusting plate 33 is provided with a screw hole or nut that cooperates with the adjusting bolt 36. A connecting rod 37 connected to the tension spring 13 is also installed on the adjusting plate 33. The fastening bolt 35 is fixed in position relative to the N-type clamp body 5. After loosening the nut of the fastening bolt 35, the adjusting bolt 36 is rotated to drive the adjusting plate 33 to move relative to the N-type clamp body 5, thereby adjusting the position of the connecting rod 37 on the adjusting plate 33 and adjusting the initial length and tension of the tension spring 13 between the connecting rod 37 and the pull rod 12.

[0034] In order to protect the tension spring 13 without interfering with the rotation of the pull rod 12 and the position adjustment of the adjusting bolt 36 and the connecting rod 37, Figure 12 As shown, a shield 38 can be mounted on the fastening bolt 35. The shield 38 has a relief groove 39 that cooperates with the arc-shaped limiting groove 14. The pull rod 12 passes through the relief groove 39. The shield 38 also has a relief hole 40 that cooperates with the adjusting bolt 36 and the connecting rod 37. The provision of the relief groove 39 and the relief hole 40 allows the position of the pull rod 12, the adjusting bolt 36, and the connecting rod 37 to be adjusted on the shield 38 without interfering with the shield 38. At the same time, the provision of the shield 38 also provides corresponding protection for the internal tension spring 13.

[0035] Furthermore, in order to monitor the clamping status of the fixture in real time and provide feedback to the ground operator, ensuring that the fixture is securely mounted before the drone 1 is driven away, an auxiliary bracket 41 can be installed on the N-type clamp body 5. The auxiliary bracket 41 is provided with a camera 42 and a GPS module 43. The camera 42 can monitor the rotational position of the wire flip clamping plate 8 and the angle steel flip clamping plate 9. The camera 42 allows the ground operator to observe the connection status of the fixture at the mounting position in real time. After confirming that the connection is reliable, subsequent operations can be performed to drive the drone 1 away. The provision of the GPS module 43 can provide real-time feedback on the position of the entire mechanism, ensuring that the drone 1 is controlled to fly to the designated test position of the line.

[0036] Furthermore, in order to make it easier for the fixture in the hoisting flight state to land at the designated detection position of the line, reduce the difficulty of controlling the flight of the drone 1, and increase the opening at the bottom of the fixture, both ends of the bottom of the N-type clamp body 5 can be installed with flared guide plates 44. Even if the opening at the bottom of the hoisted fixture is not aligned with the wire or cross-arm tower material to be hung, under the guidance of the flared guide plate 44, the position to be tested will enter the opening of the fixture during the downward movement of the fixture, and push the flip clamping plate to rotate, so as to achieve stable hanging of the fixture.

[0037] Furthermore, in order to avoid unstable clamping due to failure of the flipping clamping plate after the fixture is hung, and to avoid the fixture being separated from the position to be tested, the end of the opening position in the N-type clamp body 5 can be installed with an anti-drop plate 45 that can be rotated to open and close. The anti-drop plate 45 is fixed to the N-type clamp body 5 through a rotating shaft, and a second torsion spring 47 is installed on the rotating shaft. The second torsion spring 47 always has the tendency to rotate the anti-drop plate 45 to block the opening of the N-type clamp body 5.

[0038] When the fixture is moved down to the designated inspection position, the conductor or cross-arm tower material can overcome the elastic force of the second torsion spring 47 to push the anti-drop plate 45 upward to rotate, thereby entering the opening of the fixture. When the conductor or cross-arm tower material moves up to be completely separated from the anti-drop plate 45, under the elastic force of the second torsion spring 47, the anti-drop plate 45 can be rotated again to seal the opening, thereby achieving secondary tightening of the fixture.

[0039] The method for performing a grounding operation using the drone-mounted tool for hanging and removing a transmission line tower ground wire according to the present invention comprises the following steps:

[0040] ① Check on the ground that the drone 1, connecting rod frame 2, hanging ring 3, and suspension rope are operating normally, the angle steel end clamp, grounding wire 4, and wire end clamp are firmly connected, the tension spring 13 and flip clamping plate of the angle steel end clamp and wire end clamp are operating normally, the video signal is normal, and the connection confirmation mechanism displays normally.

[0041] ② Connect the drone mounting ring 3 to the hook of the angle steel end fixture, connect the retraction rope to the hook on the wire end fixture, and the drone operator will fly the entire set of equipment to the vicinity of the cross arm of the tension tower or straight tower to prepare for the mounting operation.

[0042] ③ Control the drone to first hang the angle steel end clamp, control the drone to hang the tower end clamp on the crossarm tower material, disengage the drone hanging ring and hook, observe and confirm the flip clamping plate to tighten the tower material for the second time, observe the video screen on the ground, and stop when the connection is reliable and firm.

[0043] ④ Control the drone and then hang the wire end clamp. Adjust the drone's position to above the wire, lower the suspension rope, and observe through the camera that the wire end clamp is hanging on a sub-wire. Observe and confirm that the wire end clamp is flipped over and tightened again. Ensure that the wire end clamp clamps the wire. Observe the picture on the ground and stop when the connection is reliable and firm.

[0044] ⑤ After the grounding wire is hung, the clamping mechanism of the angle steel end clamp and the conductor end clamp ensures a reliable and firm connection within 10 days.

[0045] ⑥ When removing the grounding wire, control the drone to remove the wire end clamp and the angle steel end clamp in turn.

[0046] ⑦ The drone transports the entire set of equipment to the ground, and the grounding wire hanging and removal work is completed.

[0047] The drone-mounted tool for hanging and removing grounding wires from transmission line towers described in the present invention redefines the technical standards for grounding operations on transmission lines through the deep integration of mechanical structure innovation and intelligent control technology, providing key technical equipment support for building an intrinsically safe power grid. Its technical indicators have reached the international leading level and have significant economic and social benefits.
