Description

Technical Field

[0001] This invention belongs to the field of power engineering technology, specifically a grounding wire attachment and removal device using a drone. Background Technology

[0002] In the power transmission line outage maintenance system, to ensure the personal safety of personnel working on outage lines and to eliminate the risk of accidental electric shock from accidental energization or induced current, industry standards clearly require that voltage testing, grounding wire installation, and removal be carried out sequentially at both ends of the transmission line to be maintained. Reliable grounding wire installation is an indispensable safety protection measure for high-voltage transmission line maintenance. With the continuous upgrading of domestic power transmission technology, ultra-high voltage and extra-high voltage transmission lines are gradually becoming the main transmission architecture of the power grid. The voltage level of transmission equipment continues to increase, and the overall size and structural span of the equipment are also increasing. Traditional manual installation and removal of grounding wire devices and related work methods are no longer suitable for the operational requirements of new ultra-high voltage and extra-high voltage transmission lines. The problems of outdated traditional grounding wire equipment structure and lagging operation modes are becoming increasingly prominent, making it difficult to meet the current safety and efficiency requirements of high-voltage power grid maintenance.

[0003] Existing traditional grounding wire operation methods have many substantial drawbacks in UHV transmission line maintenance sites: On the one hand, grounding wires suitable for UHV conditions are long and heavy, making manual connection and removal cumbersome and difficult, requiring multiple workers to coordinate and complete the work. This results in a large manpower input and long overall operation time, seriously affecting the efficiency of transmission line maintenance and making it difficult to adapt to time-sensitive scenarios such as emergency repairs. On the other hand, for maintenance work on the conductors and insulator strings in the substation section of the transmission line, the traditional method of manually climbing towers to connect grounding wires results in workers being outside the effective protection range of the grounding wire, posing a significant risk of electric shock. This paper proposes a grounding wire connection and removal device using drones to solve the above problems. Summary of the Invention

[0004] To address the problems mentioned in the background art, this invention provides a grounding wire attachment and removal device using drones, which solves the problems of large overall length and heavy weight of the grounding wire, and the cumbersome and difficult manual attachment and removal process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grounding wire device for attaching and detaching drones, comprising two symmetrically arranged side plates and a hanger fixed to the top of the two side plates. A controller and a battery are fixedly connected to one of the side plates, and a reducer is fixedly connected to the middle of the side plate. A worm gear is fixedly connected to the output end of the reducer via a coupling, and a worm wheel meshes with the outer side of the worm gear. A clamping rod is rotatably connected to the other side plate, and the worm wheel is coaxially and fixedly connected to the clamping rod. A guide rope wheel is rotatably connected between the two side plates. A connection port is provided at the bottom of the side plate, and a wiring assembly is provided on the connection port; the wiring assembly includes a grounding socket box, a grounding plug, a rope connector, and a connector. The grounding socket box includes a socket bracket, a clamping plate, and a tension spring. The socket bracket has a ring array of slots adapted to the clamping plate. Both ends of the clamping plate have limiting slots adapted to the tension spring on the side away from the socket bracket. A grounding plug is inserted into the grounding socket box. A rope connector is fixed to the middle of the grounding plug, and a grounding soft copper wire is fixed to the bottom of the grounding plug.

[0006] Preferably, the side plate has a hook groove at the end away from the hanger.

[0007] Preferably, the connector secures the grounding socket box to the connection port using bolts.

[0008] Preferably, the grounding plug is an integrally formed rotary cylindrical structure, which includes, from top to bottom, a head plug section, a middle transition ring section, and a lower end wiring sleeve section; The top of the head plug section is provided with a central through hole for threading a soft copper wire, and the upper end of the head plug section is provided with a large guide slope to adapt to insertion into the grounding socket box; the middle transition ring section is provided with a limiting step, which cooperates with the locking piece to lock and fasten; the outer periphery of the middle transition ring section is provided with an annular inclined structure, when the grounding plug is pulled outward, the middle transition ring section pushes the locking piece outward to disengage from the limiting step, thereby unlocking and disengaging the plug; The lower end wiring sleeve section is a straight cylindrical structure, used to install and fix the grounding soft copper wire. The grounding soft copper wire passes through the central through hole of the head plug section and is electrically connected to the grounding plug.

[0009] Preferably, a remote control is also provided, the remote control panel is provided with clamping control button and releasing control button; the controller has a built-in wireless receiving module, the remote control sends clamping and releasing commands to the controller through wireless signal, and the controller drives the reducer to rotate after receiving the signal.

[0010] Preferably, the top of the hanger is provided with a hook ring, and the drone can lift and transport the entire wire end fixing device by attaching the hook ring with a matching rope.

[0011] Preferably, an insulated transfer rope is threaded onto the guide rope wheel. One end of the insulated transfer rope passes through the center hole of the grounding socket box and is bound to the rope joint. The other end of the insulated transfer rope hangs down to the ground for manual pulling by the operator. The insulated transfer rope slides on the surface of the guide rope wheel to achieve the lifting and lowering of the grounding plug.

[0012] Preferably, the tension spring is sleeved on the outside of multiple sets of clamping plates. Under normal conditions, the tension spring clamps the clamping plates inward, so that the inner side of the clamping plate fits against the limiting step to lock the grounding plug. When the tension spring is pulled, it expands outward with the clamping plates and undergoes elastic deformation. The pulling force causes the clamping plates to reset and hold the grounding plug tightly.

[0013] Preferably, the opening stroke of the clamping piece matches the annular inclined surface structure of the grounding plug. After the clamping piece is fully opened, it completely disengages from the limiting step of the grounding plug, and the grounding plug freely exits the grounding socket box.

[0014] Preferably, the surface of the guide rope wheel is provided with an anti-slip and wear-resistant coating, and the groove of the guide rope wheel is adapted to the outer diameter of the insulated transmission rope to limit the deviation and swaying of the insulated transmission rope.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention utilizes drone-mounted hoisting operations, eliminating the traditional manual tower climbing method for installing and removing grounding wires on ultra-high voltage (UHV) transmission lines. This solves the safety hazards associated with manual tower climbing, such as falls from heights and electric shocks. The entire installation and removal operation requires only two ground operators working remotely with the drone. Compared to a traditional five-person work team, this reduces personnel input and lowers the probability of accidents, fundamentally eliminating the safety risks of high-altitude operations on UHV towers and significantly improving the safety level of grounding wire installation and removal operations. This invention utilizes a specialized locking wiring assembly comprised of a socket bracket, a clamping plate, and a tension spring. By leveraging the tension spring's constant clamping of the clamping plate and the clamping plate's locking mechanism with the grounding plug's limiting step, it effectively resists external interference such as transmission line vibration and outdoor wind disturbances. This significantly improves the connection tightness between the grounding plug and the grounding socket box, completely avoiding the grounding protection failure and maintenance safety hazards caused by loose grounding wire connections and poor contact in traditional grounding operations. Furthermore, the overall structure and interface dimensions of the device are precisely adapted to the structure of ultra-high voltage and extra-high voltage line towers and conductors, resulting in a wide range of operational adaptability. Even in complex and special terrain environments such as mountainous areas and lines with sharp bends, it maintains stable and reliable grounding performance, demonstrating extremely strong environmental adaptability. This invention simplifies the entire process of installing and removing grounding wires by employing a combination of drone-based precise positioning and hoisting with remote ground control. It leverages the coordinated operation of a reducer, worm gear transmission structure, and insulated rope traction structure to streamline the process. Ground personnel can independently operate the equipment, monitor its status, and perform installation and removal operations without the need for multiple on-site personnel. This significantly simplifies the workflow, reduces labor costs, and enables rapid installation and removal of grounding wires, making it highly suitable for time-sensitive scenarios such as emergency power repairs.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 7 As shown, the present invention provides a grounding wire device for attaching and detaching drones. This device includes two symmetrically arranged side plates 1 and a hanger 2 fixed to the top of the two side plates 1. A controller 3 and a battery 4 are fixedly connected to one side plate 1, and a reducer 5 is fixedly connected to the middle of the side plate 1. A worm gear 7 is fixedly connected to the output end of the reducer 5 via a coupling 6, and a worm wheel 8 meshes with the outer side of the worm gear 7. A clamping rod 18 is rotatably connected to the other side plate 1, and the worm wheel 8 is coaxially and fixedly connected to the clamping rod 18. A guide rope wheel 9 is rotatably connected between the two side plates 1. A connection port 17 is provided at the bottom of the side plate 1, and a wiring assembly is provided on the connection port 17. The wiring assembly includes a grounding socket box, a grounding plug 13, a rope connector 14, and a connector 16. The grounding socket box includes a socket bracket 10, a clamping piece 11, and a tension spring 12. The socket bracket 10 has a ring array of slots that are compatible with the clamping piece 11. Both ends of the clamping piece 11 have limiting slots that are compatible with the tension spring 12 on the side away from the socket bracket 10. The grounding plug 13 is inserted into the grounding socket box. The rope connector 14 is fixedly connected to the middle of the grounding plug 13. The grounding soft copper wire 15 is fixedly connected to the bottom of the grounding plug 13.

[0020] The above-mentioned scheme utilizes symmetrically arranged side plates 1 as the overall load-bearing base, providing a stable installation reference for the top hanger 2, the middle reducer 5, the guide rope wheel 9, and the lower wiring assembly. The overall frame structure has high strength and uniform stress distribution, effectively bearing various loads during hoisting, traction, and clamping operations, preventing deformation and shaking during operation. An independent electrical control system composed of controller 3 and battery 4 continuously supplies power to the entire automatic control and transmission mechanism. Combined with the built-in wireless receiver module of controller 3, it can accurately receive control signals from the ground remote controller, achieving remote automated operation control. The worm gear transmission mechanism, composed of reducer 5, coupling 6, worm 7, and worm wheel 8, possesses self-locking transmission and speed-up torque characteristics, precisely driving the clamping rod 18 to complete clamping and releasing actions, ensuring the wire clamping is securely fixed and will not loosen due to external vibration. The connection port 17 at the bottom of side plate 1 provides a precise installation point for the wiring components. Combined with the bolt fixing method of connector 16, the grounding socket box can be securely locked to the bottom of side plate 1, ensuring convenient disassembly and maintenance and high connection reliability. The top mounting ring of the hanger 2 is adapted to drone hoisting operations, enabling rapid device mounting, lifting, and aerial transport, suitable for high-altitude, long-distance operations. The guide rope wheel 9, in conjunction with the externally extending insulated transfer rope, limits and guides the lifting trajectory of the rope joint 14 and the grounding plug 13. Simultaneously, the anti-slip and wear-resistant coating on the surface of the guide rope wheel 9, along with the wheel groove structure adapted to the rope diameter, effectively limits the deviation, swaying, and slippage of the insulated transfer rope during operation, ensuring a smooth and stable lifting process for the grounding plug 13, significantly improving the stability and accuracy of disassembly and assembly operations.

[0021] like Figures 1 to 7 As shown, a hook groove is provided at the end of the side plate 1 away from the hanger 2; the connector 16 fixes the grounding socket box to the connection port 17 with bolts; It is also equipped with a remote control, with clamping and releasing control buttons on the remote control panel; the controller 3 has a built-in wireless receiving module, and the remote control sends clamping and releasing commands to the controller 3 via wireless signals. After receiving the signals, the controller 3 drives the reducer to rotate; the top of the hanger 2 is equipped with a hook ring, and the drone is hoisted to the hook ring via the matching rope to realize the lifting and transportation of the entire wire end fixing device; an insulated transfer rope is threaded on the guide rope wheel 9. One end of the insulated transfer rope passes through the center hole of the grounding socket box and is bound to the rope joint 14. The other end of the insulated transfer rope hangs down to the ground for the operator to pull manually; the insulated transfer rope slides on the surface of the guide rope wheel to realize the lifting and pulling of the grounding plug 13. The surface of the guide rope wheel 9 is equipped with an anti-slip and wear-resistant coating, and the wheel groove of the guide rope wheel 9 is adapted to the outer diameter of the insulated transfer rope to limit the deviation and sway of the insulated transfer rope.

[0022] The above-mentioned solution allows the device to provide auxiliary mounting points during UAV positioning operations via hook slots at the end of side plate 1, improving the stability of the device during aerial mounting and effectively preventing displacement or swaying during operation, thus adapting to high-altitude floating operation conditions. Connector 16 uses a bolt-fastened assembly method to securely and detachably fix the grounding socket box to the connection port 17 on side plate 1. This not only ensures accurate installation of the wiring components and a firm overall assembly, preventing structural loosening due to long-term vibration, but also facilitates later disassembly, inspection, parts replacement, and maintenance. The matching remote controller works in conjunction with the wireless control system of controller 3. Relying on the built-in wireless receiving module of controller 3, it accurately receives ground remote control commands, enabling long-distance, contactless control of the reducer 5 for forward and reverse rotation, precisely completing the clamping and loosening of wires, completely replacing manual close-range operation, and adapting to ultra-high voltage and high-risk operation scenarios. The top of the gantry 2 features a hook-on ring structure whose dimensions are compatible with the drone's lifting rope, enabling rapid hoisting and docking. This allows for the aerial lifting, transport, and precise positioning of the entire device, meeting the needs of high-altitude, long-distance, and tower-free operations. An insulated transfer rope, threaded inside the guide wheel 9, is bound at one end to the rope connector 14 and hangs to the ground at the other. Guided by the steering action of the guide wheel 9, it stably transmits the pulling force from ground personnel to the grounding plug 13, facilitating smooth lifting, locking, and unlocking of the grounding plug 13. Simultaneously, the anti-slip and wear-resistant coating on the surface of the guide wheel 9 effectively reduces rope slippage and prevents slippage during operation, adapting to different pulling conditions. Furthermore, the precise match between the guide wheel 9's groove and the outer diameter of the insulated transfer rope effectively limits lateral deviation and swaying during operation, ensuring precise lifting and traction of the grounding plug 13 and smooth movement, further enhancing the stability and standardization of the entire device's hanging and dismantling operations.

[0023] like Figures 3 to 6 As shown, the grounding plug 13 is an integrally formed rotating cylindrical structure, which includes, from top to bottom, a head plug section, a middle transition ring section, and a lower end wiring sleeve section. The head plug section has a central through hole at the top for threading a soft copper wire, and a large guide slope at the upper end of the head plug section to fit into the grounding socket box; the middle transition ring section has a limiting step, which cooperates with the locking piece 11 to lock and fasten; the middle transition ring section has an annular slope structure on its outer periphery. When the grounding plug 13 is pulled outward, the middle transition ring section pushes the locking piece 11 outward to open and disengage from the limiting step, thereby unlocking and disengaging the plug. The lower end wiring sleeve section is a straight cylindrical structure, used to install and fix the grounding soft copper wire 15. The grounding soft copper wire 15 passes through the center through hole of the head plug section and is electrically connected to the grounding plug 13. The tension spring 12 is sleeved on the outside of multiple sets of clamping plates 11. Under normal conditions, the tension spring 12 clamps the clamping plates inward, so that the inner side of the clamping plate 11 fits against the limiting step to lock the grounding plug 13. When the tension spring 12 is pulled, it expands outward with the clamping plate 11 and undergoes elastic deformation. The pulling force causes the clamping plate 11 to reset and hold the grounding plug 13 tightly.

[0024] The opening stroke of the clamping plate 11 matches the annular inclined surface structure of the grounding plug 13. After the clamping plate 11 is fully opened, it completely disengages from the limiting step of the grounding plug 13, and the grounding plug 13 is freely released from the grounding socket box.

[0025] The above-mentioned design features a one-piece molded rotary cylindrical grounding plug 13, which boasts strong overall structure, stable conductivity, and high mechanical strength, effectively avoiding the problems of loosening, poor contact, and breakage associated with split structures. Specifically, the large guide slope structure at the upper end of the head plug section allows for quick and precise insertion of the grounding plug 13 into the grounding socket box during aerial alignment operations, reducing the difficulty of alignment and assembly. The central through-hole structure of the head plug section ensures the through-penetration of the grounding soft copper wire 15, achieving a reliable conductive connection between the grounding plug 13 and the grounding soft copper wire 15. The limiting step and annular slope of the intermediate transition ring section form the core structure for unlocking and locking. Under normal conditions, it can precisely cooperate with the locking plate 11 to achieve locking and fixation. During pulling operations, it can be automatically opened and unlocked by pushing with the slope, exhibiting strong mechanical linkage and reliable operation. The lower wiring sleeve section adopts a straight cylindrical structure, which can stably mount and fix the grounding soft copper wire 15, preventing the wire from loosening and falling off, and ensuring the continuity and stability of grounding conductivity. The socket bracket 10 features a ring-shaped array of slots that evenly limit the arrangement of multiple locking plates 11, ensuring uniform circumferential force and good locking symmetry in the locking structure. The tension spring 12, in conjunction with the outer limiting groove assembly structure of the locking plate 11, can inwardly tighten the locking plate 11 under normal conditions, ensuring a tight fit between the locking plate 11 and the limiting step of the grounding plug 13, achieving reliable locking and preventing detachment. When the grounding plug 13 is pulled to unlock, it can elastically deform outward along with the locking plate 11. After unlocking, it can quickly reset due to its own elastic tension, achieving automatic rebound locking. Simultaneously, the opening stroke of the locking plate 11 precisely matches the annular inclined structure of the grounding plug 13. After the locking plate 11 is fully opened, it can completely disengage from the limiting step of the grounding plug 13 without mechanical jamming or structural interference, ensuring that the grounding plug 13 can smoothly and steadily exit the grounding socket box, significantly improving the smoothness and reliability of grounding wire removal operations.

[0026] Working principle and usage process of this invention: Before operation, the grounding plug 13 is assembled into the grounding socket box, and the clamping plate 11 is tightened by the tension spring 12. The clamping plate 11 and the limiting step of the grounding plug 13 are locked together to complete the pre-fixation of the wiring assembly. The entire device is then hung on the drone's sling by the top hanging ring of the hanger 2. The drone carries the device to the ultra-high voltage line operation position for precise alignment. The ground operator sends control commands to the controller 3 via the remote controller. The controller 3 drives the reducer 5 to rotate, which in turn drives the worm gear 7 to rotate via the coupling 6. Through the meshing transmission between the worm gear 7 and the worm wheel 8, the clamping rod 18, which is coaxially connected to the worm wheel 8, is driven to rotate, thus achieving the clamping and fixing of the device at the line conductor. After fixing, the ground personnel pull the insulated transfer rope that passes through the guide rope wheel 9. The insulated transfer rope pulls the grounding plug 13 upward through the rope joint 14, so that the grounding soft copper wire 15 is in place and laid out, finally completing the entire grounding wire mounting and installation operation. After the line maintenance work is completed, ground personnel issue a release command again via remote control. Controller 3 controls the reducer 5 to rotate in reverse, driving the clamping rod 18 to rotate through the worm gear 7 and worm wheel 8 transmission structure, thus releasing the clamping limit between the device and the transmission line. Ground personnel then continuously pull the insulating transfer rope downwards. The annular inclined surface of the intermediate transition section of the grounding plug 13 pushes the clamping plate 11 outwards, causing the tension spring 12 to elastically deform, disengaging the clamping plate 11 from the limiting step of the grounding plug 13, thus unlocking the wiring assembly. Continuous traction allows the grounding plug 13 to be pulled out of the grounding socket box, completing the separation of the grounding soft copper wire 15. Finally, the drone-mounted hanger 2 removes the entire set of side plates 1, wiring assemblies, and other equipment from the work site, completing the fully automated grounding wire removal operation.
