Description

Technical Field

[0001] This utility model relates to the field of power network maintenance and emergency repair technology, and in particular to a device for a drone to attach and retrieve a grounding wire. Background Technology

[0002] Grounding wire connection devices are used in power systems to connect and disconnect grounding wires from cables. Connecting and disconnecting grounding wires is an important and frequent operation in power system maintenance and repair. Traditional grounding wire connection devices have several shortcomings. Firstly, their operation often relies on manual labor at heights, requiring workers to climb to high places and facing serious safety risks such as falls and electric shocks, posing a significant threat to their personal safety. Secondly, manual operation is inefficient; in complex terrain or harsh environments, manual operation is difficult and time-consuming, failing to meet the needs of rapid and efficient power maintenance. Furthermore, the connection stability and reliability of traditional devices also have certain problems, with the possibility of grounding wires becoming loose or detaching, affecting the safe operation of the power system.

[0003] To address this, this utility model proposes a drone-mounted grounding wire attachment device. By employing a drone equipped with a wire attachment frame, the grounding wire attachment operation is remotely and automatically performed, reducing safety risks and improving work efficiency. Through the ingenious combination of grippers, locking devices, and springs, the connection between the grounding wire and the cable is reliably fixed and easily released, ensuring connection stability and operational convenience. This provides a safer, more efficient, and reliable solution for the maintenance and repair of power equipment. Utility Model Content

[0004] Technical problem to be solved: Traditional grounding wire installation relies on manual labor, which poses serious safety risks such as falls and electric shocks.

[0005] To achieve the above objectives, this utility model proposes a device for attaching a grounding wire to a drone, comprising a wire-attaching frame and a spring. Hooks for attaching the frame to a cable are provided on both sides of the middle portion of the wire-attaching frame. Pullers are rotatably connected to both sides of the middle portion of the wire-attaching frame, with two pullers positioned opposite each other below the hooks. Pull ropes are fitted onto both pullers, with one end of each rope connected to a winch and the other end connected to a pull rod. A connector is positioned between the two pull rods, and both pull rods are bolted to both sides of the connector. Rotating the winch allows for the raising and lowering of the pull ropes. When the wire-attaching frame is attached to the cable, rotating the winch raises the pull ropes, thereby lifting the connector to the underside of the cable.

[0006] In one example, a slide rod is slidably connected to the middle of the connector. A locking device for locking the slide rod is installed between the slide rod and the connector. A rotating rod is rotatably connected inside the locking device. A limit block is fixedly connected to the end of the rotating rod away from the rotatably connected part of the locking device. A path groove is opened on the side of the slide rod that slides inside the locking device near the rotating rod. Multiple path points a, b, d, e, g, h and two inclined surfaces c and f are provided on the path groove. A spring is sleeved on the outer side of the slide rod.

[0007] In one example, a pressing plate is fixedly connected to the top of the slide rod, two grippers are rotatably connected to the upper side of the connector, and a groove is opened on the lower side of each of the two grippers. A push rod is fixedly connected to the lower side of the slide rod, and the push rod moves inside the two grooves.

[0008] In one example, the bottom of the connector is fixedly connected to a wire.

[0009] In one example, a drone is also included, with a mounting bracket fixedly connected to its bottom. The drone hooks onto a cable hanger via the hanger, which in turn causes a hook on the cable hanger to attach to a cable.

[0010] In one example, the winch is either a manual winch or an electric winch.

[0011] In one example, the design of the latch and slot inside the locking device ensures reliable locking when the slide bar is pressed down and smooth unlocking when the slide bar is pressed down again.

[0012] In one example, the shape and size of the hook are designed to fit the specifications of common cables.

[0013] The device for attaching a grounding wire to a drone proposed in this utility model has the following beneficial effects:

[0014] 1. In this utility model, by using a drone to carry a wire-hanging frame, the operation of grounding wire hanging is remotely and automatically achieved. In traditional grounding wire hanging operations, workers often need to perform dangerous and tedious operations at high altitudes, posing a high safety risk. However, this utility model uses a drone to accurately lift the wire-hanging frame to the cable location, allowing workers to operate it from a safe area on the ground. This greatly reduces the safety hazards of falls and electric shocks caused by working at heights. At the same time, the flexibility and maneuverability of the drone allows the wire-hanging frame to reach the target location quickly and accurately. Compared with manual operation, this significantly improves work efficiency and reduces work time. In addition, this remote and automated operation mode reduces reliance on manpower. Especially in areas with complex terrain that are difficult for personnel to reach, this device can play a better role and ensure the smooth progress of power maintenance and other work.

[0015] 2. In this utility model, the ingenious combination of grippers, locking devices, and springs achieves reliable fixing and convenient release of the connection between the grounding wire and the cable. During the wire hanging process, pulling the pull rope causes the compression plate on the connector to strike the cable, triggering the grippers to close and be locked by the locking device, ensuring that the connector is firmly suspended on the cable. This connection method is stable and reliable, effectively ensuring that the grounding wire will not fall off during use, thus guaranteeing the safe operation of the power system. When removing the wire, pulling the pull rope again triggers the locking device to unlock a second time. Under the action of the spring rebound force, the grippers open, easily releasing the fixing of the connector. Subsequently, the connector can be smoothly moved to the ground. The entire process is simple to operate, requiring no complicated tools or excessive manual intervention. It not only improves the efficiency of hanging and removing grounding wires but also ensures the reliability and stability of the connection and release operations, providing convenience for the maintenance and repair of power equipment.

[0027] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0028] like Figures 1-9 As shown in the figure, an embodiment of this utility model proposes a device for attaching a grounding wire to a drone, which includes a wire-attaching frame 1 and a spring 16. Hooks 2 are provided on both sides of the middle portion of the wire-attaching frame 1, and the hooks 2 are used to attach the wire-attaching frame 1 to the cable. Pulleys 3 are rotatably connected to both sides of the middle portion of the wire-attaching frame 1, and the two pulleys 3 are positioned opposite each other below the hooks 2. Pull ropes 4 are fitted onto each of the two pulleys 3. One end of each pull rope 4 is connected to a winch 5, and the other end of each pull rope 4 is connected to a pull rod 6. A [missing information - likely a type of support or mechanism] is provided between the two pull rods 6. The connector 7 and two pull rods 6 are fixed to both sides of the connector 7 by bolts 8. The winch 5 can be rotated to raise and lower the pull rope 4. When the cable hanger 1 is hung on the cable, the pull rope 4 can be raised by rotating the winch 5 to lift the connector 7 to the lower side of the cable. During the process of the pull rope 4 pulling the connector 7 upward, the bottom end of the connector 7 is fixedly connected to the grounding wire 9. During the upward movement, the weight of the grounding wire 9 will force the bottom end of the connector 7 to always be in a downward state, so that the two claws 10 at the top of the connector will contact the cable first.

[0029] Two grippers 10 are rotatably connected to the upper side of the connector 7. The two grippers 10 are respectively located on both sides of the connector 7. Both grippers 10 are bent in shape, and each gripper 10 has a sliding groove 11 on its lower side. Two sliding rods 12 are slidably connected to the middle of the connector 7. A locking device 13 is installed between the sliding rods 12 and the connector 7. The locking device 13 is used to lock the sliding rods 12. A spring 16 is sleeved on the outer side of the sliding rods 12. The spring 16 is located between the lower side of the extrusion plate 15 and the top of the connector 7. Its own rebound force pushes the extrusion plate 15 upward, thereby causing the sliding rods 12 to move upward. Combined with the spring 16, it triggers the locking function of the locking device 13. A rotating rod 19 is rotatably connected inside the locking device 13. A limit block 20 is fixedly connected to the end of the rotating rod 19 away from the rotatable connection point with the locking device 13. A path groove 21 is opened on the side of the sliding rod 12 near the rotating rod 19 inside the locking device 13. Figure 8 As shown, the path slot 21 has multiple path points a, b, d, e, g, h and two inclined surfaces c and f;

[0030] Initially, under the rebound force of spring 16, slide rod 12 extends into the connector 7. At this time, limit block 20 is at point a. When the extrusion disc 15 impacts the cable and moves towards one side of connector 7, it pushes slide rod 12 into connector 7. As slide rod 12 moves, it moves path groove 21, causing limit block 20 to move from the bottom to the top of path groove 21. Since point b is offset to the right relative to point a, when limit block 20 moves downward, b will guide limit block 20, guiding it to move upward from the left side of path groove 21. When it reaches the top, after the impact, connector 7 falls. At this time, the cable impacts the extrusion disc. When the restriction of 15 ends, the spring 16 pushes the extrusion plate 15 upward, which in turn drives the slide bar 12 upward. When the slide bar 12 moves upward, it drives the path groove 21 upward. Meanwhile, the limiting block 20 moves downward inside the path groove 21. When the limiting block 20 moves upward from the left side of the path groove 21 to the top of the path groove 21, due to the rightward tilt of c, the limiting block 20 is offset to the right. When the spring 16 pushes the path groove 21 upward and the limiting block 20 moves downward inside the path groove 21, the limiting block 20 will be hooked at point e of the path groove 21. At this time, the path groove 21 and the limiting block 20 interact, so that the slide bar 12 cannot continue to move upward.

[0031] When the extrusion plate 15 strikes the cable again and moves closer to the side of the connector 7, the limiting block 20 at point e moves to point g to the right under the constraint of the inclined surface f. After the impact ends, point e no longer restricts the limiting block 20. Under the action of the spring 16's rebound force, it pushes the extrusion plate 15 upward and then drives the path groove 21 upward. The limiting block 20 inside the path groove 21 tends to move downward. Since the position of point g is offset to the right compared to point h, point g guides the limiting block 20 to move downward from the right side of the path groove 21 and return to point a. Thus, the locking device 13 locks and unlocks the slide bar 12.

[0032] A pressing plate 15 is fixedly connected between the top ends of the two slide rods 12, and a push rod 14 is fixedly connected between the bottom ends of the two slide rods 12. The push rod 14 passes through the groove 11 on the lower side of the two grippers 10. By pulling the pull rope 4, the connector 7 jumps upward continuously under the pull of the pull rope 4, causing the pressing plate 15 at its top to continuously hit the cable. The pressing plate 15 pushes the slide rod 12, causing the push rod 14 to move downward. The push rod 14 moves inside the slide rod 12, causing the two grippers 10 to rotate, causing the top ends of the two grippers 10 to close, restricting the cable between the two grippers 10. During the downward movement of the slide rod 12, the latch inside the locking device 13 is triggered, and then... To prevent the slide bar 12 from springing back, the tops of the two grippers 10 remain closed, thus suspending the connector 7 on the cable. The bottom of the connector 7 is fixedly connected to the wire 9. The pull ropes 4 are distributed on both sides of the connector 7. The two pull ropes 4 pull the connector 7 upward at the same time, and the connector 7 cannot shift left or right. In addition, during the process of the pull ropes 4 pulling the connector 7 upward, the bottom of the connector 7 is fixedly connected to the grounding wire 9. During the upward movement, the weight of the grounding wire 9 will force the bottom of the connector 7 to always be in a downward state, so that the two grippers 10 at the top of the connector will contact the cable first. Therefore, the grippers 10 will definitely be able to clamp the cable.

[0033] After the work is completed, pull the pull rope 4 again to make the connector 7 jump upwards continuously under the pull of the pull rope 4, so that the pressing plate 15 at the top of the connector 7 will hit the cable continuously. The pressing plate 15 pushes the slide rod 12 and drives the push rod 14 to move downwards. When the slide rod 12 moves downwards again, the lock inside the locking device 13 is triggered for the second time, so that the locking device 13 releases the restriction on the movement of the slide rod 12. Then, under the action of the spring 16 rebound force, the slide rod 12 is pushed to move upwards. The slide rod 12 drives the push rod 14 to move upwards in the slide groove 11. The push rod 14 pushes the top of the two grippers 10 to open, thereby releasing the clamp on the cable. At this time, by rotating the winch 5 to release the pull rope 4 from the weight of the connector 7 itself and the downward force of the wire 9, the connector 7 can be moved to the ground along the pulley 3.

[0034] The bottom of the drone 17 is fixedly connected to the bracket 18. The bracket 18 hooks the cable hanger 1. Then the drone 17 takes off and lifts the cable hanger 1 to the cable. By controlling the drone 17, the hook 2 on the cable hanger 1 is hung on the cable, thereby hanging the cable hanger 1 on the cable.

[0035] In summary, the specific process of hanging the cable is as follows: First, hook the cable hanger 1 onto the bottom of the drone 17 via the hanger 18, then fix the lever 6. At this time, control the drone 17 to take off, lift the cable hanger 1 and move it to the cable. During this process, the lever 6 does not move, but as the cable hanger 1 continues to rise, the pull rope 4 is pulled longer and longer until the drone 17 is controlled to hook the hook 2 on the cable hanger 1 onto the cable. Then, control the drone 17 to separate the hanger 18 from the cable hanger 1 and return to the drone 17.

[0036] Then, the connector 7 is fixed between the two pull rods 6 by bolts 8. The winch 5 is turned to wind up the pull rope 4, which drives the connector 7 to rise and get closer to the cable. When it is about to get close to the cable, the pull rope 4 is pulled with force, which makes the pull rope 4 drive the connector 7 to jump up. Then the extrusion plate 15 hits the cable continuously. The extrusion plate 15 hits the cable, which pushes the slide rod 12 and drives the push rod 14 to move down. The push rod 14 moves in the slide groove 11, which drives the two clamps 10 to rotate and close their tops, restricting the cable between the two clamps 10. During the downward movement of the slide rod 12, the internal latch of the locking device 13 is triggered, locking the slide rod 12 and keeping the tops of the clamps 10 closed. The connector 7 is then suspended on the cable, completing the cable hanging.

[0037] When retrieving the cable, pull the rope 4 again, causing the connector 7 to jump upwards continuously under the pull of the rope 4. The squeeze plate 15 hits the cable, pushing the slide rod 12 and causing the push rod 14 to move downwards. When the slide rod 12 moves downwards again, the internal latch of the locking device 13 is triggered for the second time. The latch separates from the slot, releasing the restriction on the movement of the slide rod 12. Under the rebound force of the spring 16, the slide rod 12 moves upwards, causing the push rod 14 to move upwards in the slide groove 11, pushing the top of the two grippers 10 to open, releasing the clamp on the cable. Rotate the winch 5 to loosen the rope 4. Under the action of the connector 7's own weight and the downward force of the wire 9, the connector 7 is moved to the ground along the pulley 3. Operate the drone 17 to remove the cable hanger 1 from the cable and bring it back, thus completing the cable retrieval work.
