[0022] Embodiment 1 Please refer to Figure 1-2 As shown, an insulating rope erection unmanned aerial vehicle traction device for insulating rope erection, the insulating rope erection unmanned aerial vehicle traction device for insulating rope erection includes: An eight-rotor unmanned aerial vehicle 1, a connection shell assembly 2 is fixedly connected to the bottom surface of the eight-rotor unmanned aerial vehicle 1, and the connection shell assembly 2 is rotatable; A winding and traction unit 3 is fixedly arranged in the inner cavity of the connection shell assembly 2, and the winding and traction unit 3 is used for winding and traction movement of the insulating rope; The rewinding speed control unit 4 is fixedly arranged in the inner cavity of the connection shell assembly 2, and the rewinding speed control unit 4 is used to control the rewinding traction speed according to the wind force magnitude; The wind deviation compensation assembly 5 is fixedly arranged at the bottom surface of the connection shell assembly 2, and the wind deviation compensation assembly 5 is used to perform deviation compensation on the insulating rope according to the wind force magnitude; Through the above technical solution, by the combined use of the rewinding speed control unit 4 and the rewinding traction unit 3, the rewinding traction speed can be automatically adjusted according to the wind force magnitude during rewinding traction. When the wind force is large, the rewinding traction speed is slowed down, which allows the operator to have more time to observe the surrounding environment and timely adjust the flight attitude of the unmanned aerial vehicle and the direction of the insulating rope, ensuring the safety of the operation. When the wind force is small, the rewinding traction speed is increased to improve the operation efficiency, realizing the function of automatic adjustment. Moreover, the adjustment does not require an additional power source, which is convenient to use. Further, the present application also provides the wind deviation compensation assembly 5. The wind deviation compensation assembly 5 can automatically rotate and adjust the angle according to the wind direction and drive the insulating rope to deflect a certain angle, thereby compensating for the excessive deviation caused by the wind.

[0023] As a further technical solution, please refer to Figure 3 and Figure 4 As shown, the connection shell assembly 2 includes a connection shell 201, a connection circular seat 202, and a first guide cylinder 203. The connection circular seat 202 is fixedly arranged at the bottom surface of the eight-rotor unmanned aerial vehicle 1, and the bottom end of the connection circular seat 202 is rotatably connected to the upper surface of the connection shell 201. The connection shell 201 is streamlined, and the first guide cylinder 203 is fixedly arranged at the bottom of the inner cavity of the connection shell 201. Through this technical solution, the first guide cylinder 203 can play a role in guiding the insulating rope during rewinding traction movement, avoiding the excessive deviation phenomenon caused by vibration during the rewinding traction movement; In an alternative embodiment, a rotational damping mechanism can be added at the rotational connection between the bottom end of the connection circular seat 202 and the upper surface of the connection shell 201 to avoid excessive rotation.

[0024] The coiling and traction unit 3 includes a fixed bracket 301, a rotating rod 302, a first bevel gear 303, a driving motor 304, a rotating shaft 305, a second bevel gear 306, a sleeve 307, and a conical coiling roller 308. The fixed bracket 301 is fixedly arranged at the side wall position of the connecting shell 201. A rotating rod 302 is rotatably connected to the fixed bracket 301. One end of the rotating rod 302 is fixedly connected to a first bevel gear 303. A driving motor 304 is fixedly installed on the side wall of the connecting shell 201. The end of the output shaft of the driving motor 304 is fixedly connected to one end of the rotating rod 302. A rotating shaft 305 is rotatably connected to the inner cavity of the connecting shell 201. One end of the rotating shaft 305 is fixedly connected to a second bevel gear 306. The second bevel gear 306 meshes with the first bevel gear 303. Through this technical solution, the rotation of the rotating rod 302 can be driven by the operation of the driving motor 304, thereby driving the rotation of the first bevel gear 303. The rotation of the second bevel gear 306 can be driven by the rotation of the first bevel gear 303, and then the rotation of the rotating shaft 305 can be driven; A limiting groove 3051 is formed in the arc wall of the rotating shaft 305. The sleeve 307 is sleeved on the arc wall of the rotating shaft 305 and is slidably matched with the rotating shaft 305. A protrusion matching with the limiting groove 3051 extends from the arc inner wall of the sleeve 307. Through this technical solution, the sleeve 307 can translate left and right on the rotating shaft 305 and can also be driven to rotate when the rotating shaft 305 rotates. Limiting disks 3071 are fixedly connected to both ends of the sleeve 307. A conical coiling roller 308 is fixedly connected to the arc wall of the sleeve 307. Through this technical solution, the rotation of the conical coiling roller 308 can be driven by the rotation of the sleeve 307. The rotation of the conical coiling roller 308 can wind and traction the insulating rope to move, realizing the traction and recovery function of the insulating rope.

[0025] As a specific technical solution, please refer to Figure 5 and Figure 6As shown in the figure, the winding speed control unit 4 includes a wind guiding fin 401, a rotating rod 402, a turbine 403, a rectangular fixed housing 404, a gear 405, a guide rod 406, a moving seat 407, a rack 408, a control spring 409, a moving slider 410, a U-shaped control frame 411, a threaded rod 412, a third bevel gear 413 and a fourth bevel gear 414. The wind guiding fin 401 is fixedly arranged at the tail end of the connecting shell 201. Through this technical solution, when the eight-rotor unmanned aerial vehicle 1 flies in the air for the winding and traction work of the insulating rope, when there is a wind flow in the air, the wind guiding fin 401 can be driven to deflect automatically under the action of aerodynamic force, so that the arc-shaped front end of the connecting shell 201 faces the wind blowing direction, realizing the function of automatically adjusting the position of the connecting shell 201 according to the wind direction change; The rotating rod 402 is arranged in the inner cavity of the connecting shell 201 and is rotatably connected to the connecting shell 201. A rectangular fixed housing 404 is fixedly connected in the inner cavity of the connecting shell 201. One end of the rotating rod 402 extends into the inner cavity of the rectangular fixed housing 404 and is rotatably connected to the rectangular fixed housing 404. The other end of the rotating rod 402 extends to the outer wall of the connecting shell 201. A turbine 403 is fixedly connected to the front end of the rotating rod 402. Through this technical solution, due to the setting of the wind guiding fin 401, the connecting shell 201 can deflect automatically in a strong wind environment, so that the front end of the connecting shell 201 faces the wind blowing direction, and thus the turbine 403 faces the wind blowing direction. The wind can drive the turbine 403 to rotate, and when the wind force is greater, the torque generated by blowing the turbine 403 is also greater; The guide rod 406 is fixedly arranged in the inner cavity of the connection shell 201. A moving seat 407 is slidably connected to the guide rod 406. One end of a control spring 409 is fixedly connected to the side wall of the moving seat 407, and the other end of the control spring 409 is fixedly connected to the side wall of the inner cavity of the connection shell 201. A rack 408 is fixedly connected to the upper surface of the moving seat 407. The gear 405 is fixedly arranged on the arc wall of the rotating rod 402. The gear 405 meshes with the rack 408. Through this technical solution, when the turbine 403 rotates due to the wind blowing, the rotation of the turbine 403 can drive the rotating rod 402 to rotate, and then drive the gear 405 to rotate. Thus, the rotation of the gear 405 drives the rack 408 to move. The movement of the rack 408 can drive the moving seat 407 to move, so that the control spring 409 deforms and generates a reverse force on the moving seat 407. The greater the wind force, the greater the torque generated by blowing the turbine 403, the more turns the rotating rod 402 rotates, so that the more turns the gear 405 rotates, and the greater the deformation of the control spring 409, finally balancing the rotational torque. When the wind force decreases, through the action of the control spring 409, it can drive the rack 408 to move in the reverse direction, and then drive the gear 405 to rotate in the reverse direction, realizing the function of automatic adjustment.

[0026] As a preferred technical solution, please refer to Figure 7 Figure 8 and Figure 9As shown, a moving slider 410 is slidably connected in the inner cavity of the rectangular fixed shell 404. A U-shaped control frame 411 is slidably connected to the side wall of the rectangular fixed shell 404. The U-shaped control frame 411 is fixedly connected to the moving slider 410. The U-shaped control frame 411 extends to the limiting disc 3071. A number of balls 4111 are rotatably fitted and embedded on the inner wall of the U-shaped control frame 411, and the balls 4111 are in contact with the limiting disc 3071. A threaded rod 412 is rotatably connected between the upper and lower walls of the inner cavity of the rectangular fixed shell 404. The threaded rod 412 passes through the moving slider 410 and is in threaded cooperation with the moving slider 410. A third bevel gear 413 is fixedly connected to the arc-shaped wall of the threaded rod 412. A fourth bevel gear 414 is fixedly connected to one end of the rotating rod 402. The third bevel gear 413 and the fourth bevel gear 414 are meshed with each other. Through this technical solution, when the rotating rod 402 rotates driven by the wind blowing on the turbine 403, it can drive the fourth bevel gear 414 to rotate. Thus, the rotation of the fourth bevel gear 414 can drive the third bevel gear 413 to rotate, and further drive the threaded rod 412 to rotate. By the rotation of the threaded rod 412, the moving slider 410 can be driven to move, thereby driving the U-shaped control frame 411 to move. By the movement of the U-shaped control frame 411, the limiting disc 3071 can be driven to move, thereby driving the sleeve 307 to move. From the perspective of Figure 4 Figure 4 , the sleeve 307 moves to the right, so that the smaller-diameter end of the conical winding roller 308 moves directly above the first guide cylinder 203. When the conical winding roller 308 rotates to wind the insulating rope, due to the smaller diameter, the winding and traction speed is slower, which allows the operator more time to observe the surrounding environment and timely adjust the flight attitude of the drone and the direction of the insulating rope, ensuring the safety of the operation. When the wind force becomes smaller, the rotating rod 402 moves in the reverse direction, thereby driving the U-shaped control frame 411 to move in the reverse direction, and further driving the conical winding roller 308 to move to the left. The leftward movement of the conical winding roller 308 can make the larger-diameter end move directly above the first guide cylinder 203. When the conical winding roller 308 performs winding and traction movement, due to the larger diameter, the traction speed is increased, improving the working efficiency of winding and traction. From the above description, it can be seen that when the outdoor wind force is large, the winding and traction speed can be automatically slowed down to avoid instability caused by excessive speed. After the wind force decreases, the winding and traction speed is automatically increased to improve the working efficiency, realizing the function of automatic adjustment.

[0027] As a further technical solution, please refer to Figure 10As shown, the wind deflection compensation assembly 5 includes a fixed tripod 501, a wind plate 502, a connecting bracket 503, a fixed guide rod 504, a moving slider 505, a connecting tripod 506, an offset rod bracket 507 and a second guide cylinder 508. The fixed tripod 501 is fixedly arranged at the bottom of the connecting shell 201. A wind plate 502 is rotatably connected to the fixed tripod 501. A fixed guide rod 504 is fixedly connected to the bottom of the connecting shell 201. A moving slider 505 is slidably connected to the fixed guide rod 504. One end of a connecting bracket 503 is rotatably connected to the bottom end of the moving slider 505. The other end of the connecting bracket 503 extends to the side wall of the wind plate 502 and is rotatably connected to the wind plate 502. A push rod 509 is fixedly connected to the side wall of the moving slider 505. The connecting tripod 506 is fixedly arranged at the bottom of the connecting shell 201. An offset rod bracket 507 is rotatably connected to the connecting tripod 506. The upper end of the offset rod bracket 507 contacts one end of the push rod 509. A second guide cylinder 508 is fixedly connected to the bottom end of the offset rod bracket 507. Through this technical solution, by passing the insulating rope through the second guide cylinder 508, a guiding and limiting effect is achieved. When the outdoor wind force is large, the wind can cause the connecting shell 201 to automatically rotate and adjust the angle, making the front end face the wind, so that the wind plate 502 can face the wind blowing direction directly. The thrust generated by the wind can drive the wind plate 502 to deflect. As Figure 10 From the perspective of Figure 10 , the wind blowing drives the wind plate 502 to deflect to the left. The leftward deflection of the wind plate 502 can push the moving slider 505 to move leftward, thereby driving the push rod 509 to move leftward. Thus, the leftward movement of the push rod 509 pushes the upper end of the offset rod bracket 507 to move leftward, thereby driving the bottom end of the offset rod bracket 507 to move rightward, causing the second guide cylinder 508 to move rightward. When pulling the insulating rope, by sleeving the second guide cylinder 508 on the insulating rope, a guiding effect on the insulating rope is achieved. The rightward movement of the second guide cylinder 508 can drive the insulating rope to deflect in the opposite direction of the wind blowing direction, driving the upper end of the insulating rope to deflect in the opposite direction, thereby compensating for the deflected distance caused by the wind and avoiding the phenomenon of excessive deflection caused by the wind.

[0028] Embodiment 2 A working method of an insulating rope erection unmanned aerial vehicle traction device includes the following steps: a. Pass the insulating rope through the second guide cylinder 508 and the first guide cylinder 203 in sequence and fix it at the starting end of the conical winding roller 308.

[0029] b. The unmanned aerial vehicle 1 vertically takes off to the target operation height. The wind guiding tail fin 401 automatically deflects under the action of the wind, driving the connecting shell 201 to rotate to the front windward direction, making the turbine 403 face the airflow directly.

[0030] c. The drive motor 304 starts, drives the rotating shaft 305 to rotate slowly through the first bevel gear 303 and the second bevel gear 306, and makes the conical winding roller 308 wind the insulating rope slowly at the initial diameter (the larger end) to eliminate slack.

[0031] d. When the wind force increases, the rotation speed of the turbine 403 increases, drives the rotating rod 402 to rotate, and drives the threaded rod 412 to rotate through the fourth bevel gear 414 and the third bevel gear 413. The threaded rod 412 pushes the moving slider 410 to move rightward, and the U-shaped control frame 411 drives the sleeve 307 to move rightward, so that the smaller diameter end of the conical winding roller 308 is aligned with the first guiding cylinder 203 to reduce the winding speed. The reaction force of the control spring 409 balances the wind torque to ensure the stability of the winding speed. When the wind force decreases, the spring resets and drives the sleeve 307 to move leftward to resume high-speed winding.

[0032] e. The connection shell 201 rotates with the wind guiding tail wing 401 to the windward direction, and the wind plate 502 deflects to one side under the action of the wind force. The wind plate 502 pushes the moving slider 505 to move leftward through the connection bracket 503, and the ejector rod 509 drives the upper end of the offset rod frame 507 to move leftward and the lower end to move rightward, driving the second guiding cylinder 508 to deflect rightward. The second guiding cylinder 508 pulls the insulating rope to deflect in the opposite direction of the wind blowing direction to offset the influence of wind deflection.

[0033] f. When the drone 1 arrives at the target position, the drive motor 304 rotates reversely, and the conical winding roller 308 slowly releases the insulating rope at the smaller diameter end to ensure a smooth lowering process.
