Specific embodiments

[0021] Embodiment 1

[0022] Please refer to Figures 1-3 , in the embodiment of the present invention, a high-voltage wire auxiliary climbing device based on a drone includes a fixed frame 11. The fixed frame 11 is an inverted U-shaped structure with a closed upper end and an opening on one side of the lower end. A second guiding plate 27 is provided on the right side of the opening. The lower end of the second guiding plate 27 deflects away from the opening. A vertically arranged first guiding plate 26 is provided on the fixed frame 11 on the left side of the opening. The first guiding plate 26 and the second guiding plate 27 cooperate to form an eight-shaped opening structure for guiding the high-voltage wire into the interior of the fixed frame 11. A guiding inclined plane 23 for facilitating the high-voltage wire to slide out is provided inside the fixed frame 11 on the left side of the opening. Two positioning blocks 25 are symmetrically provided on the lower end surface of the fixed frame 11. A fixed pulley 30 for facilitating the rope to bypass is rotatably provided between the two positioning blocks 25. During actual use, the rope is bypassed around the fixed pulley 30. One end of the rope is connected to a winch, and the other end of the rope is connected to a hanging basket for the maintenance personnel to stand on. Then, by starting the winch, the maintenance personnel can be hoisted up;

[0023] Inside the fixed frame 11, a support roller 20 for pressing tightly against the high-voltage wire is rotatably provided. At the top of the fixed frame 11, an adsorption iron block 16 is provided. The adsorption iron block 16 is fixedly connected to the fixed frame 11 through a connecting suspension plate 17. The connecting suspension plate 17 is connected to the fixed frame 11 through a sliding member. When it is necessary to lift the device, the electromagnet at the bottom of the drone is energized to adsorb the adsorption iron block 16, and then the drone is used to lift the device above the high-voltage wire, and then the adsorption iron block 16 is released. Under the guidance of the first guide plate 26 and the second guide plate 27, the support roller 20 will contact the top of the high-voltage wire;

[0024] On the side of the fixed frame 11, a camera 24 for obtaining the maintenance position is provided. The camera 24 is electrically connected to a controller 14 provided on the top of the fixed frame 11. The controller 14 is provided with a wireless module for wireless interaction with the control terminal;

[0025] On the fixed frame 11, a limit blocking member is further provided for cooperating with the support roller 20 to prevent the fixed frame 11 from detaching from the high-voltage wire;

[0026] The limit blocking member includes a limit hole 22 opened on one side of the fixed frame 11. The limit hole 22 is provided on the side away from the second guide plate 27. A limit insertion rod 29 is slidably fitted in the limit hole 22. A self-locking pushing mechanism for driving the limit insertion rod 29 to extend and retract is provided between the limit insertion rod 29 and the connecting suspension plate 17;

[0027] The self-locking pushing mechanism includes an expansion spring 15 arranged at the upper end of the controller 14. The upper end of the expansion spring 15 is fixedly connected to the bottom of the adsorption iron block 16. A rectangular groove 35 is formed on the upper side of the limit insertion rod 29. A transmission rack 34 is arranged in the rectangular groove 35 in a matching manner. The transmission rack 34 meshes with the gear 28. The gear 28 is coaxially arranged on the fixed rotating shaft 32. The two ends of the fixed rotating shaft 32 are respectively rotatably connected to the positioning side plates on the outside of the fixed frame 11. A return coil spring 33 is arranged between one end of the fixed rotating shaft 32 and the positioning side plate. The return coil spring 33 is used to make the fixed rotating shaft 32 rotate back. A traction wheel 31 is coaxially arranged at the other end of the fixed rotating shaft 32. A traction rope 19 is wound around the traction wheel 31. The upper end of the traction rope 19 is fixedly connected to the traction block 18 on the outside of the connecting suspension plate 17. When the adsorption iron block 16 does not receive a traction force, at this time, the limit insertion rod 29 extends along the limit hole 22 to the lower side of the support roller 20, thereby preventing the fixed frame 11 from falling off the high-voltage line. When being towed by the drone, under the action of the self-weight of the fixed frame 11, the expansion spring 15 will be stretched. At this time, the guiding slider 12 slides along the guiding chute 13. In this way, the traction rope 19 wound around the traction wheel 31 will be pulled out. The traction wheel 31 will drive the fixed rotating shaft 32 to rotate. The fixed rotating shaft 32 drives the gear 28 to rotate. The gear 28 meshes with the transmission rack 34, so as to pull out the limit insertion rod 29 from the inside of the fixed frame 11. Subsequently, when the support roller 20 first contacts the high-voltage line, when the gravity traction is lost, the expansion spring 15 will gradually return to its original position. In this way, under the traction of the return coil spring 33, the traction wheel 31 will rewind the traction rope 19. In this way, the gear 28 and the transmission rack 34 will cooperate to drive the limit insertion rod 29 to re-insert into the fixed frame 11, so as to play a limiting role;

[0028] The sliding member includes a guiding chute 13 arranged on the connecting suspension plate 17. The guiding chute 13 is slidably arranged with the guiding slider 12 on the outside of the fixed frame 11. In this way, the fixed frame 11 and the connecting suspension plate 17 are slidably arranged;

[0029] A protection box 21 for wrapping the limit insertion rod 29 and the gear 28 is arranged on the outside of the fixed frame 11. A traction through hole for facilitating the passing of the traction rope 19 is arranged at the upper end of the protection box 21. By arranging the protection box 21, the transmission components can be protected;

[0030] The shaft end of the support roller 20 is connected to a traveling motor for driving its rotation. In this way, the traveling motor can drive the support roller 20 to rotate, so that the fixed frame 11 can be displaced to adjust the maintenance position. An anti-slip layer is distributed on the outside of the support roller 20.

[0031] The working principle of the present invention is as follows: In this application, for the existing design requirements, a rope is wound around a fixed pulley 30. One end of the rope is connected to a winch, and the other end of the rope is connected to a hanging basket that facilitates the maintenance personnel to stand. An iron block 16 is adsorbed by an electromagnet at the bottom of the unmanned aerial vehicle (UAV). Then, the UAV is started to suspend the fixed frame 11 above the high-voltage line. When being pulled by the UAV, under the action of the self-gravity of the fixed frame 11, the expansion spring 15 will be stretched. At this time, the guiding slider 12 slides along the guiding chute 13, so that the towing rope 19 wound around the towing wheel 31 will be pulled out, and the towing wheel 31 will drive the fixed rotating shaft 32 to rotate. The fixed rotating shaft 32 drives the gear 28 to rotate. The gear 28 meshes with the transmission rack 34, thereby pulling out the limit insertion rod 29 from the inside of the fixed frame 11. Subsequently, when the support roller 20 first contacts the high-voltage line, when the gravity traction is lost, the expansion spring 15 will gradually reset. In this way, under the traction of the reset winding spring 33, the towing wheel 31 will rewind the towing rope 19, which will cause the gear 28 and the transmission rack 34 to cooperate to drive the limit insertion rod 29 to re-insert into the fixed frame 11, thereby playing a limiting role.

[0032] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
