Description

Technical Field

[0001] This invention relates to the field of bird spike technology, and in particular to a method for live-line installation of bird spikes on power transmission lines using unmanned aerial vehicles (UAVs). Background Technology

[0002] Bird damage to power transmission lines has become one of the main external factors causing line flashover and tripping. Bird spikes are currently the most widely used physical bird-proofing devices. However, the installation of traditional bird spike devices relies on manual tower climbing and power outage operations, which poses risks of falling from heights and electric shocks. The operation is also inefficient and difficult to carry out in complex terrain, seriously affecting the reliability of power supply.

[0003] With the increasing breadth and depth of drone applications, using drones to replace manual labor for bird spike installation has become a feasible technological direction. Drones have advantages such as maneuverability, no terrain restrictions, and remote control capabilities, which can effectively avoid the risks of high-altitude operations and improve installation efficiency. Existing bird spike devices for power transmission lines lack automatic alignment, automatic closing, and automatic release mechanisms, making it impossible to achieve live installation by drones. This has significant application value in solving the problems of high safety risks and low efficiency of traditional manual installation methods and improving the level of bird damage prevention for power transmission lines. Summary of the Invention

[0004] To address the problems of high-altitude operation risks, low installation efficiency, susceptibility to complex terrain, and the need for power outages in traditional manual tower climbing for bird spike installation, this invention provides a method for live-line installation of bird spikes using drones. This method enables rapid installation via remote drone control, significantly improving operational safety and installation efficiency, and adapting to various complex environments without requiring power outages.

[0005] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: A method for installing bird spikes on power transmission lines using a drone includes two horizontally placed bird-repelling shells that are joined together on the power cable to form a bird-repelling tube. Several bird spike units are provided on the bird-repelling shells. The bottoms of the two bird-repelling shells are connected to the same mounting shaft by a hinge, and a spring clip is fitted on the mounting shaft, with the two ends of the spring clip abutting against the outside of the two bird-repelling shells respectively. A support rod is rotatably connected to the top of a bird deterrent shell. Before two bird deterrent shells are joined together to form a bird deterrent tube, the free end of the support rod abuts against the inner side of the top of another bird deterrent shell, so that the bird deterrent shell forms an opening larger than the diameter of the cable. The bird deterrent shell is detachably mounted on top of the drone via a connector.

[0006] As another optimized solution for live installation of bird spikes on power transmission lines using drones, the top of the connector is connected to a connector hole on a connecting frame via a plug rod, and the connecting frame is fixedly connected to both ends of the mounting shaft.

[0007] As another optimized solution for the live installation of bird spikes by drones on the aforementioned power transmission lines, the length of the support rod is 1.5 to 2.5 times the diameter of the conventional power transmission conductor.

[0008] As another optimized solution for installing bird spikes on power transmission lines using drones, the inner side of the bird deterrent shell is hinged with several spring plates.

[0009] As another optimized solution for installing bird spikes on the power transmission lines using drones, rubber pads are fixedly connected to the inner sides of both ends of the bird deterrent shell.

[0010] As another optimized solution for live-line installation of bird spikes by drones on the aforementioned power transmission lines, the bird spike unit includes a spike body and a mounting plate, with the spike body detachably connected to the mounting plate via anti-detachment plugs.

[0011] As another optimized solution for the live installation of bird spikes by drones on the aforementioned power transmission lines, the spikes include long spikes with a height of 100-120mm and short spikes with a height of 60-80mm, and the long and short spikes are arranged alternately along the base of the bird spike unit, with the spikes radiating outwards.

[0012] As another optimized solution for installing bird spikes on the power transmission lines using drones, the inner wall of the bird-repellent shell is provided with silicone rubber fiberglass cloth.

[0013] As another optimized solution for installing bird deterrents on power transmission lines using drones, the bird deterrent shell is made of high-strength general-purpose ASA plastic.

[0014] As another optimized solution for installing bird spikes on power transmission lines using drones, the bird deterrent shell is provided with elastic buckles and tenon holes at both ends to form a complete bird spike assembly.

[0015] The present invention has the following beneficial effects: 1) A bird deterrent tube is set up by assembling bird deterrent shells. With the cooperation of support rods and spring clips, it can be mounted by drones and locked when it touches the wire without manual intervention. The connectors on the drone and the support rods are detachable. After installation, the drone can automatically separate when it descends without tangling or jamming.

[0016] 2) The bird deterrent shell is made of ASA material through injection molding and modular assembly process, as well as modular bird spike unit and bird spike body plug-in assembly structure. It has high production efficiency, good dimensional accuracy and consistency, can be freely spliced ​​in length, and can be replaced individually if partially damaged, making it suitable for mass industrial production.

Detailed Implementation

[0019] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. Parts not explained in the following embodiments of the present invention, such as the model and operation method of the drone, are all considered to be prior art known or should be known by those skilled in the art.

[0020] Example 1

[0021] like Figure 1 As shown, a method for installing bird spikes on power transmission lines using a drone includes two horizontally placed bird deterrent shells 1. The two bird deterrent shells 1 are joined together on the cable to form a bird deterrent tube. Several bird spike units 2 are provided on the bird deterrent shells 1 for physically driving away birds from approaching and staying. like Figure 3 As shown, the bottoms of the two bird deterrent shells 1 are connected to the same mounting shaft 4 through a hinge, forming an openable clamping structure. A spring clip 5 is sleeved on the mounting shaft 4. The elastic element of the spring clip 5 is a torsion spring. One end of the torsion spring is fixedly connected to the mounting shaft 4. The torsion spring is spirally wound along the axial direction of the mounting shaft 4 and extends into a clamping piece at the free end. The two ends of the spring clip 5 (i.e. the clamping piece part) abut against the outside of the two bird deterrent shells 1 respectively, providing a continuous clamping force to the two bird deterrent shells 1 and ensuring a stable and tight fit when assembled. A support rod 6 is rotatably connected to the top of a bird deterrent shell 1. Before the two bird deterrent shells 1 are assembled to form a bird deterrent tube, the free end of the support rod 6 abuts against the inner side of the top of the other bird deterrent shell 1. Before the bird deterrent shell 1 is mounted on the drone 8, the two bird deterrent shells 1 need to be manually opened, and then the free end of the support rod 6 is abutted against the inner side of the top of the other bird deterrent shell 1 to keep the two shells open, so that the bird deterrent shell 1 forms an opening larger than the cable diameter, so that it can cross and fit the power transmission cable during the mounting operation. The bird deterrent shell 1 is detachably mounted on top of the drone 8 via connector 9.

[0022] In this embodiment, as Figure 4 As shown, the top of the connector 9 is connected to the insertion hole on a connector 3 via the insertion rod 10, and the connector 3 is fixedly connected to both ends of the mounting shaft 4.

[0023] In this embodiment, the length of the support rod 6 is 1.5 to 2.5 times the diameter of a conventional power transmission conductor. This range ensures sufficient span to accommodate conductors of different diameters, reduces operational requirements, and facilitates alignment during drone hoisting.

[0024] In this embodiment, several spring plates 7 are hinged to the inner side of the bird deterrent shell 1. When the bird deterrent shell 1 is assembled onto the cable, the spring plates 7 elastically press against the surface of the cable, which can increase the clamping friction to prevent axial slippage, adapt to slight differences in wire diameter, and avoid rigid contact that could damage the outer layer of the cable.

[0025] In this embodiment, as Figure 1 As shown, rubber pads 11 are fixedly connected to the inner sides of both ends of the bird deterrent shell 1. After the shell is closed, it forms a flexible embrace around the cable, which serves as an auxiliary buffer and insulation, and further protects the cable insulation layer from wear.

[0026] In this embodiment, as Figure 2 As shown, the bird spike unit 2 includes a spike body and a mounting plate. The spike body is detachably connected to the mounting plate via an anti-detachment plug, which facilitates quick on-site assembly and partial replacement, and ensures that the spike body will not loosen or fall off due to vibration or external force during long-term use.

[0027] In this embodiment, the spikes include long spikes with a height of 100-120mm and short spikes with a height of 60-80mm. The long and short spikes are arranged alternately along the base of the bird-proof spike unit 2, and the spikes are distributed radially outward to form a dense, multi-layered three-dimensional protective barrier. This ensures that there are no gaps for birds to stay above the crossarm and directly above the conductor insulator string, effectively preventing birds from staying, nesting, or defecating in key parts of the tower for a long time, thereby actively preventing bird droppings flashover and short circuit tripping accidents.

[0028] In this embodiment, the inner wall of the bird deterrent shell 1 is provided with silicone rubber fiberglass cloth, which significantly improves electrical safety performance, weather resistance and anti-aging properties, as well as buffering and flame retardant properties, thereby effectively enhancing the overall reliability and service life of the bird deterrent equipment in harsh outdoor environments.

[0029] In this embodiment, the bird deterrent shell 1 is made of high-strength general-purpose ASA plastic, which ensures injection molding flowability and structural strength, and has sufficient material weather resistance, low-temperature toughness and insulation stability.

[0030] In this embodiment, the bird deterrent shell 1 has elastic buckles and tenon holes at both ends. The elastic buckles can be connected and inserted into the tenon holes, thereby connecting multiple bird deterrent shells 1 in series to form a complete bird spike assembly, which has the effect of preventing birds from landing on the power transmission cable.

[0031] Working principle: First, preparation work needs to be carried out on the ground. On the ground, the two bird-repelling shells 1 are opened to a certain angle around the mounting shaft 4 through the bottom hinge. The support rod 6 is rotated to a horizontal state, so that its free end abuts against the top inner side of the other bird-repelling shell 1, keeping the two bird-repelling shells 1 in a stable open state. At this time, the spring clip 5 is in a compressed and energy-storing state because its two ends are stretched open by the shell. Then, the plug hole on the connecting frame 3 is quickly connected to the plug rod 10 on the top of the connecting part 9 above the drone 8, completing the rigid mounting of the bird-repelling tube to the drone. The drone 8 carries the device and flies to the target power transmission line directly below it. The drone 8 hovers directly below the target power line and slowly rises, so that the two open bird-repelling shells 1 are diagonally below the power line on both sides. The drone 8 continues to rise and ensures that the two bird-repelling shells 1 are in a stable open state. The shell 1 is accurately aligned with the wire and inserted into the opening area between the two bird deterrent shells 1 to avoid jamming or misalignment. When the wire enters the opening between the two bird deterrent shells 1, the drone 8 continues to rise slowly, causing the wire to squeeze the support rod 6 and eventually causing the free end of the support rod 6 to break free from the top constraint on the inner side of the other bird deterrent shell 1. At this time, the elastic potential energy stored in the spring clip 5 is released instantly, and its two ends forcefully close inward, pushing the two bird deterrent shells 1 to rotate towards each other around the bottom mounting shaft 4 and close together. Finally, the wire is completely covered in the inner cavity of the bird deterrent tube formed by the splicing of the two bird deterrent shells 1. At this point, the device holds the wire tightly by the clamping force continuously applied by the spring clip 5, completing the mechanical installation. The drone 8 then descends and disengages from the connector 9 by quickly separating the plug rod 10 from the plug hole, returning to perform the next task.
