Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV that performs contact operations with live wires. Background Technology

[0002] A drone generally consists of five main parts: the drone platform, the flight control system, the communication module, the ground control station, and the payload. The drone platform is the actual flying body; the flight control system is responsible for the drone's flight stability and navigation; the communication module is responsible for data transmission; the ground control station is the interface between the operator and the drone; and the payload is the equipment used to collect environmental data and perform specific tasks.

[0003] Overhead transmission lines are an important component of the power grid, serving as the equipment for transmitting electrical energy. Compared to other power equipment, transmission lines are characterized by their long length, wide coverage, and complex operating environment. Since overhead cables require regular maintenance and repair during use, and these repairs typically involve live-line work, the current common method involves workers climbing to the heights to perform the work. This method is not only difficult to operate but also highly dangerous. Therefore, the use of drones for high-altitude operations has become widely adopted.

[0004] However, overhead power transmission lines often cross mountainous areas, forest areas, rivers and other regions. The maintenance of power transmission lines is not completely restricted by the weather. For example, work still needs to be carried out in light rain or light wind. In the existing technology, drones are sensitive to environmental conditions such as wind, rain, fog and low temperature. Strong winds can cause drones to lose attitude control and make it difficult to accurately hover near the power lines for maintenance. Utility Model Content

The limiting block moves downward and the bottom end of the limiting block fits into the outer wall of the wire. The two sets of limiting plates and the limiting block cooperate to clamp and fix the wire, so that the drone body is fixed on the upper end of the wire.

[0017] Preferably, the two sets of toothed plates are displaced, and the two sets of toothed plates are respectively engaged with the two sets of transmission gears, so the two sets of transmission gears rotate, thereby driving the two sets of transmission shafts to rotate.

[0018] The present invention is further configured such that two sets of connecting shafts are movably installed inside the main body of the drone, and the two sets of connecting shafts are respectively connected to two sets of transmission shafts by toothed synchronous belts.

[0019] Preferably, the two sets of drive shafts rotate, and the two sets of drive shafts are connected to the two sets of connecting shafts by toothed synchronous belts, so the two sets of connecting shafts rotate.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of this utility model will be described below based on its overall structure.

[0031] A drone that operates by contacting live wires, such as Figure 1 - Figure 5 As shown, the device includes a drone body 1, with maintenance equipment movably installed on the upper part of the drone body 1, landing gear 2 symmetrically installed on the bottom of the drone body 1, and two sets of limiting plates 14 movably installed on the bottom of the drone body 1, with the two sets of limiting plates 14 being staggered. A telescopic column 6 is movably installed inside the drone body 1, and a limiting block 7 is installed at one end of the telescopic column 6 extending to the outer wall of the drone body 1. The two sets of limiting plates are flipped so that the two sets of first grooves respectively fit the wire connection segment, the limiting block moves downward, and the bottom end of the limiting block fits the outer wall of the wire. The two sets of limiting plates and the limiting block cooperate to clamp and fix the wire.

[0032] Please see Figure 3 - Figure 4 The main body 1 of the drone is equipped with a drive motor 4 and a movable cylinder 5 is movably installed inside the main body 1 of the drone. The output end of the drive motor 4 is connected to one end of the movable cylinder 5. When the drive motor 4 is started, it drives the movable cylinder 5 to rotate.

[0033] Please see Figure 3 - Figure 4 The outer wall of the telescopic column 6 is threadedly connected to the inner wall of the movable cylinder 5. Two sets of limit columns 8 are symmetrically installed on the upper end of the limit block 7, and the outer walls of the two sets of limit columns 8 are movably connected to the inner wall of the UAV body 1. The two sets of limit columns 8 limit the limit block 7. When the movable cylinder 5 rotates, it drives the telescopic column 6 to move, thereby driving the limit block 7 to move.

[0034] Please see Figure 2 - Figure 4 The bottom of the limiting block 7 is arc-shaped and has a rubber pad layer to increase the stability of the limiting block 7 after it comes into contact with the wire.

[0035] Please see Figure 4Both sets of limiting posts 8 have reserved grooves 9 on their outer walls, and toothed plates 10 are installed on the inner walls of both sets of reserved grooves 9. When the two sets of limiting blocks 8 are displaced, they respectively drive the two sets of toothed plates 10 to be displaced.

[0036] Please see Figure 3 - Figure 5 The main body 1 of the drone has two sets of drive shafts 11 installed inside. Each set of drive shafts 11 has a drive gear 12 installed at one end. The two sets of drive gears 12 are respectively engaged with two sets of toothed plates 10. When the two sets of toothed plates 10 are displaced, they are respectively engaged with the two sets of drive gears 12. Therefore, the two sets of drive gears 12 rotate, thereby driving the two sets of drive shafts 11 to rotate.

[0037] Please see Figure 3 - Figure 5 The main body 1 of the drone has two sets of connecting shafts 13 installed inside, and the two sets of connecting shafts 13 are respectively connected to the two sets of transmission shafts 11 by toothed synchronous belts. The two sets of transmission shafts 11 rotate, and the two sets of transmission shafts 11 are respectively connected to the two sets of connecting shafts 13 by toothed synchronous belts, so the two sets of connecting shafts 13 rotate.

[0038] Please see Figure 3 - Figure 5 The outer walls of the two sets of connecting shafts 13 are fixedly connected to the inner walls of the two sets of limiting plates 14, and both sets of connecting shafts 13 are damping rotating shafts. When the two sets of connecting shafts 13 rotate, they cause the two sets of limiting plates 14 to rotate around the two sets of connecting shafts 13.

[0039] Please see Figure 3 - Figure 5 Both sets of limiting plates 14 have a first groove 15 at one end, and the inner wall of both sets of first grooves 15 is covered with a rubber layer to increase the stability of the limiting plate 14 after it comes into contact with the wire.

[0040] Please see Figure 2 - Figure 5 Each of the two sets of landing gear 2 has an auxiliary frame 3 installed at one end. The outer walls of the two sets of limiting plates 14 are provided with second grooves 16, and the inner walls of the two sets of second grooves 16 are movably connected to the outer walls of the two sets of auxiliary frames 3 respectively. In normal state, one end of the two sets of limiting plates 14 is connected to the two sets of auxiliary frames 3 respectively, and the two sets of limiting plates 14 are stored.

[0041] The working principle of this utility model is as follows: When the worker uses this drone to inspect and repair power lines, the worker can install the inspection equipment on the upper part of the drone body 1 using bolts or other fixing components. Then, the drone body 1 flies to the upper part of the power line, the drive motor 4 starts, and drives the movable cylinder 5 to rotate. The inner wall of the movable cylinder 5 is threadedly connected to the outer wall of the telescopic column 6, so the telescopic column 6 moves downward, thereby driving the limit block 7 to move downward, which in turn drives the two sets of limit columns 8 to move downward, and then drives the two sets of toothed plates 10 to move downward. The two sets of toothed plates 10 are respectively meshed with the two sets of transmission gears 12, so the two sets of transmission gears 12 rotate, thereby driving the two sets of transmission shafts 1 1. The two sets of drive shafts 11 are connected to the two sets of connecting shafts 13 by toothed synchronous belts. Therefore, the two sets of connecting shafts 13 rotate, thereby driving the two sets of limiting plates 14 to rotate around the two sets of connecting shafts 13. This causes the two sets of first grooves 15 to fit into the wire connection segment. The limiting block 7 continues to move downward, and the bottom end of the limiting block 7 fits into the outer wall of the wire. The two sets of limiting plates 14 and the limiting block 7 cooperate to clamp and fix the wire, so that the drone body 1 is fixed on the upper end of the wire. This avoids the drone from losing control due to strong winds and improves the stability of the drone body 1. The maintenance equipment on the upper end of the drone body 1 performs maintenance work on the wire.
