Description

A drone mounting structure for quick wire removal and installation Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to a drone installation structure for quick assembly and disassembly of conductors. Background Technology

[0002] With the widespread application of drone technology in power line inspection, drone-based grounding wire mounting systems have become an important technological means to replace traditional manual tower climbing operations. These systems achieve non-contact operation through an aerial platform, effectively avoiding safety risks such as falls from heights and electric arc shock. The drone-based grounding wire mounting device disclosed in Chinese authorization announcement CN219980276U is a typical example of this technology. It uses an electromagnetic push-pull mechanism to drive a locking block to clamp the wire and a control box to enable remote opening and closing operations, significantly reducing the workload. However, in practical applications, it has been found that this device requires a second, precise docking of the drone with the mounting ring during the disassembly and retrieval phase. This process reveals significant drawbacks in the following scenarios: when strong winds cause a decrease in drone hovering stability, the failure rate of mechanical docking between the mounting ring and the drone hook surges. To address these shortcomings, we propose a drone-based installation structure for rapid wire disassembly and assembly. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drone installation structure for quick wire assembly and disassembly.

[0004] To address the problems existing in the prior art, this utility model adopts the following technical solution: a drone mounting structure for quick wire detachment and reattachment, including a drone grounding wire attachment device, a guide wire disposed on the surface of the drone grounding wire attachment device, and further comprising:

[0005] The drone docking assembly includes a support rod and an assembly flange that is fixedly mounted on the upper end of the support rod;

[0006] The rope clamping assembly includes a mounting box fixedly installed at the lower end of the support rod, a first clamping plate fixedly installed on the back of the mounting box, and a second clamping plate disposed opposite to the first clamping plate. Semicircular holes are provided on the opposite surfaces of the first clamping plate and the second clamping plate.

[0007] The assembly components include a positioning ring fixedly installed on the upper surface of the drone's grounding wire attachment device, a pull rope passing through the inner wall of the positioning ring, a lifting ring fixedly installed on the surface of the support rod, and a conical stop fixedly installed at one end of the pull rope. The inner wall of the positioning ring is provided with a conical groove that matches the conical stop.

[0008] The drive assembly includes a motor fixedly mounted on the bottom wall of the mounting box, a threaded rod fixedly mounted on the output end of the motor, a through hole opened on the surface of a first clamping plate, and a threaded hole opened on the surface of a second clamping plate, wherein the threaded rod passes through the through hole and forms a helical drive with the threaded hole.

[0009] Preferably, two guide rods are fixedly installed on the back of the first clamping plate, and a guide groove is opened on the front of the second clamping plate to slide with the guide rods, and the contact surface between the guide rods and the guide groove is coated with polytetrafluoroethylene.

[0010] Preferably, the upper surface of the assembly flange is provided with mounting holes for connection with an external drone.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Please refer to Figures 1-6. This utility model provides a technical solution: a drone installation structure for quick wire removal and installation, including a drone grounding wire attachment device 10, a guide line 20 disposed on the surface of the drone grounding wire attachment device 10, and further including: a drone connection component, a pull rope clamping component, an assembly component, and a drive component.

[0028] The drone docking assembly includes a support rod 30 and an assembly flange 31 fixedly installed on the upper end of the support rod 30. The upper surface of the assembly flange 31 has mounting holes for connecting with an external drone. The support rod 30 is fixed to the bottom of the drone through the standardized mounting holes of the assembly flange 31.

[0029] The assembly components include a positioning ring 50 fixedly mounted on the upper surface of the UAV grounding wire attachment device 10, a pull rope 51 passing through the inner wall of the positioning ring 50, a lifting ring 52 fixedly mounted on the surface of the support rod 30, and a conical stop 53 fixedly mounted on one end of the pull rope 51. The pull rope 51 is a Kevlar fiber braided rope with a wear-resistant silicone coating on its surface. The pull rope 51 is passed through the positioning ring 50, and the end is fixed to the conical stop 53. Then, one end of the pull rope 51 is tied to the lifting ring 52. The lifting ring 52 can be pre-installed on the surface of the support rod 30. The inner wall of the positioning ring 50 has a conical groove 54 that matches the conical stop 53. The cone angle of the conical stop 53 is 45°-60°, and the inner wall of the conical groove 54 has an elastic rubber layer.

[0030] The rope clamping assembly includes a mounting box 40 fixedly installed at the lower end of the support rod 30, a first clamping plate 41 fixedly installed on the back of the mounting box 40, and a second clamping plate 42 disposed opposite to the first clamping plate 41. Semicircular holes 43 are provided on the opposite surfaces of the first clamping plate 41 and the second clamping plate 42.

[0031] The drive assembly includes a motor 60 fixedly mounted on the bottom wall of the mounting box 40, a threaded rod 61 fixedly mounted on the output end of the motor 60, a through hole on the surface of the first clamping plate 41, and a threaded hole on the surface of the second clamping plate 42. The threaded rod 61 passes through the through hole and forms a helical drive with the threaded hole. Two guide rods 70 are fixedly mounted on the back of the first clamping plate 41. The front of the second clamping plate 42 has a guide groove 71 that slides with the guide rods 70, and the contact surface between the guide rods 70 and the guide groove 71 is coated with polytetrafluoroethylene. The motor 60 is a waterproof stepper motor. The motor has an IP67 protection rating, and the output shaft of the motor 60 is equipped with a magnetic encoder. The motor 60 drives the threaded rod 61 to rotate. The threaded rod 61 and the threaded hole provide helical transmission. The cooperation between the guide rod 70 and the guide groove 71 prevents the second clamping plate 42 from rotating, thereby driving the first clamping plate 41 and the second clamping plate 42 to close or open. When the traction rope 51 is placed in the semi-circular hole 43, the motor 60 is started. The threaded rod 61 drives the second clamping plate 42 to slide along the guide rod 70, ensuring that the semi-circular hole 43 forms a closed clamp to hold the traction rope 51.

[0032] The side wall of the mounting box 40 is provided with heat dissipation holes, and the heat dissipation holes are embedded with dustproof mesh 44. The heat dissipation holes can dissipate heat from the motor 60.

[0033] One end of the pull rope 51 is passed through the positioning ring 50 and tied to the hanging ring 52. Then, the pull rope 51 is clamped and fixed by the pull rope clamping assembly. The drone docking assembly is connected to the drone. When the drone carries the drone grounding wire hooking device 10 to clamp the wire, the pull rope clamping assembly releases the pull rope 51. After the pull rope 51 is released from the clamping assembly, it can slide within the positioning ring 50. At this time, the drone can fly back to the ground with one end of the pull rope 51 and pull the pull rope 51 so that the conical stop 53 at the other end of the pull rope 51 enters the conical groove 54 for limiting. At this time, the pull rope 51 will be at the upper end of the clamped wire.

[0034] When it is necessary to disassemble the drone grounding wire attachment device 10, the internal drive mechanism of the drone grounding wire attachment device 10 is used to release the wire clamp (the drone grounding wire attachment device and its internal drive mechanism are existing technologies, so they will not be described in detail), and the wire is released from fixation. Then, the guide line 20 is pulled, and the drag force is used to drive the drone grounding wire attachment device 10 to detach from the wire. At this time, the pull rope 51 is attached to the surface of the wire. Using the wire as a fulcrum, the drone grounding wire attachment device 10 can be pulled. The operator only needs to pull the guide line 20 and extend the pull rope 51 to remove the drone grounding wire attachment device 10 from the air without the need for secondary operation of the drone.

[0035] The drone only needs to be attached once to complete the wire clamping. When disassembling, the wire is used as a fulcrum, and the guide line 20 directly drags the drone to detach the grounding device 10 from the wire. Ground personnel can retrieve the device by pulling the guide line 20 and adjusting the length of the pull rope 51, without the need for the drone to hover and dock twice.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
