Description

Technical Field

[0001] The present invention relates to the technical field of power distribution line operation and inspection, and in particular to a special intelligent grounding device for unmanned aerial vehicles. Background Art

[0002] In the power industry, the installation and removal of grounding wires is an important part of ensuring the safety of power construction. Although the traditional manual installation and removal method of grounding wires is widely used, it has great limitations. Operators usually need to climb up to the pole tower to operate, which is not only time-consuming and laborious, but also brings a high risk of falling and electric shock. Especially when working at high altitudes, the operator completes the installation and removal of the grounding wire at a height, and the safety hazards are even more obvious. In order to reduce the risk of falling from high altitudes for operators, some power companies have begun to use extended operating rods. This operating rod allows operators to complete the installation and removal of grounding wires on the ground, thereby avoiding the dangers brought by high-altitude operations. However, the introduction of extended operating rods has not completely solved the problem. First of all, the traditional extended operating rod is heavy, and with the weight of the grounding wire, the operation process requires the cooperation of multiple people to complete, which increases labor costs and operational difficulties, reduces operational efficiency, and creates safety risks of being hit by high-altitude objects. Secondly, on some higher pole towers, the use of this extended operating rod is also restricted, and even impossible to operate. Specifically:

[0003] The existing extended operating rod is heavy due to material and design limitations, making it inconvenient for one person to operate, resulting in low operating efficiency. Although the extended operating rod can reduce high-altitude operations, during the installation and removal of the grounding wire, electric shock, falling objects or other accidents may still occur due to operational errors. The practical scenarios of the existing extended operating rod are limited by the height of the tower. For particularly high towers, the traditional operating method is difficult to apply. The installation and removal process of the grounding wire is complicated and needs to be completed quickly and accurately.

[0004] Therefore, how to improve the efficiency of grounding wire installation and removal, reduce dependence on manpower, and expand its applicability on high towers while ensuring operational safety has become a technical problem that needs to be urgently solved in the current power industry. Summary of the invention

[0005] The present invention proposes an intelligent grounding device dedicated to drones, which is used to solve the problems of low efficiency, high work intensity and high safety risks in climbing poles to hang and remove grounding wires when grassroots operation and maintenance personnel carry out power outage maintenance operations.

[0019] Step 1. After the A-phase grounding wire clamp, the B-phase grounding wire clamp and the C-phase grounding wire clamp are all connected to the grounding wire, short-circuit the tail end of the three-phase grounding wire to the grounding pin, and then insert the grounding pin into the ground.

[0026] A method for disassembling a drone grounding device, based on the above-mentioned drone-specific intelligent grounding device, comprises the following steps:

[0027] Step I: Confirm that the drone, ladder, bracket, A-phase grounding clamp, B-phase grounding clamp, and C-phase grounding clamp are intact, and check whether the battery power and signal receiving and sending device are normal;

[0028] Step II, control the two drones to rise between the A-phase wire and the C-phase wire to the test ring of the B-phase wire and the A-phase wire or the C-phase wire; control the first drone to fly so that the drone hanging clamp of the B-phase grounding wire clamp is mounted on the rack, and control the push rod motor of the A-phase grounding wire clamp to start through the remote control, so that the guide rod drives the clamp block to loosen the test ring of the B-phase wire; control the second drone to fly so that the drone hanging clamp of the auxiliary load-bearing wire clamp is mounted on the rack; then control the two drones to rise in flight height so that the A-phase wire or the C-phase wire is out of contact with the arc-shaped touch plate of the gravity locking member, and the arc-shaped touch plate swings to form an unlocked state; then control the two drones to rise in flight height so that the test ring of the B-phase wire is disengaged from the wire clamp hook of the B-phase grounding wire clamp, and at the same time, the A-phase wire or the C-phase wire can be disengaged from the wire clamp hook of the auxiliary load-bearing wire clamp;

[0029] Step III, control the drone to descend its flight altitude, remove the B-phase grounding wire clamp and the auxiliary load-bearing wire clamp from the hanging bracket of the soft ladder, and remove the grounding wire;

[0030] Step IV, control the drone to fly to the test ring of the A-phase conductor, control the drone to fly so that the drone hanging clip of the A-phase grounding wire clamp is hung on the hanging bracket; control the push rod motor of the A-phase grounding wire clamp to start by the remote controller, so that the guide rod drives the clamp block to release the test ring of the A-phase conductor; then control the drone to rise in flight altitude, so that the test ring of the A-phase conductor is released from the wire clamp hook of the A-phase grounding wire clamp;

[0031] Step V, control the drone to descend its flight altitude, remove the A-phase grounding wire clamp from the hanging bracket of the soft ladder, and remove the grounding wire;

[0032] Step VI, repeating steps IV and V to remove the C-phase grounding wire clamp from the test ring of the C-phase conductor;

[0033] Step VII, store and organize the drone, A-phase grounding wire clamp, B-phase grounding wire clamp, C-phase grounding wire clamp, grounding wire and grounding pin to complete the disassembly of the grounding device.

[0034] The intelligent grounding device for drones has the following significant beneficial effects:

[0035] 1. Security

DETAILED DESCRIPTION

[0055] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0056] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other without conflict. It should be noted that similar numbers and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0057] In view of the time-consuming and labor-intensive problem of traditional manual grounding wire installation and removal, this embodiment proposes a special intelligent grounding device for drones; Figure 1 As shown, the intelligent grounding device dedicated to the UAV includes a UAV 1 and a soft ladder 2 installed on the landing gear of the UAV; Figure 1 and Figure 2 As shown, a bracket 3 is installed on the soft ladder 2; the drone-specific intelligent grounding device also includes an A-phase grounding clamp 4, a B-phase grounding clamp 5 and a C-phase grounding clamp 6 that can be installed on the A-phase wire, the B-phase wire and the C-phase wire through the drone 1 and the soft ladder 2.

[0058] Specifically, Figure 1 and Figure 2 As shown, the A-phase grounding wire clamp 4, the B-phase grounding wire clamp 5 and the C-phase grounding wire clamp 6 in this embodiment have the same structure, and all include a wire clamp hook 7 and a drone hook 8, as well as a remote control electric drive component for controlling the unlocking and locking of the wire clamp. Figure 3 As shown, the A-phase grounding wire clamp 4, the B-phase grounding wire clamp 5 and the C-phase grounding wire clamp 6 all include a wire clamp control box 15, the wire clamp hook 7 is installed on the wire clamp control box 15, and the drone hanging clamp 8 is hingedly installed on the wire clamp hook 7 and is located at the hook body opening side away from the wire clamp hook 7. Figure 4As shown, a battery 16, a circuit board 17 connected to the battery 16, and a push rod motor 18 connected to the battery 16 and the circuit board 17 are installed in the wire clamp control box 15; wherein the battery 16, the circuit board 17, and the push rod motor 18 are all commercially available finished products, such as: Lawnce LS18650 lithium-ion battery, Arduino Uno Rev3 circuit board, LINAKLA36 push rod motor; the push rod motor 18 is connected to a guide rod 19, and the guide rod 19 passes through the wire clamp control box 15 and is connected to a clamp block 20 that cooperates with the wire clamp hook 7. The wire clamp control box 15 is provided with a power switch 21 connected to the circuit board 17, a power display screen 22, and a charging port 23. In addition, the wire clamp control box 15 is provided with a signal receiving and sending device 26 connected to the circuit board 17, which is used to cooperate with the circuit board 17 to remotely receive the control signal of the remote control 33; the signal receiving and sending device 26 is a commercially available finished product, such as: Semtech SX1278 long-distance wireless communication module. In addition, as Figure 3 As shown, considering the connection problem of the grounding wire 10 , in this embodiment, a connecting bolt 24 connected to the grounding wire 10 is provided on the wire clamp hook 7 , and it is connected to the ground wire through the connecting bolt 24 .

[0059] Based on the above-mentioned intelligent grounding device for drones, when installing and removing the grounding wire 10, the A-phase grounding wire clamp 4, the B-phase grounding wire clamp 5 and the C-phase grounding wire clamp 6 are all installed and removed by the drone 1 in conjunction with the soft ladder 2 and the bracket 3, and are installed on the electric test ring 9 of the conductor. The A-phase grounding wire clamp 4, the B-phase grounding wire clamp 5 and the C-phase grounding wire clamp 6 are all connected to the grounding wire 10, and the ends of the three groups of grounding wires 10 are connected to the same grounding pin 11 through the three-phase short-circuit point, and the grounding pin 11 is inserted into the ground to complete the installation of the grounding device.

[0060] Furthermore, as a preferred technical solution of this embodiment, since the position of the B-phase conductor is higher than that of the A-phase conductor and the C-phase conductor, considering the load-bearing problem of the drone 1, this embodiment also designs an auxiliary load-bearing wire clamp 28 for the B-phase grounding wire installation. Specifically, Figure 5 and Figure 6As shown, the auxiliary load-bearing wire clamp 28 includes a wire clamp hook 7 and a drone hanging clamp 8, and a gravity locking member 30; the bottom of the wire clamp hook 7 is hingedly installed with a grounding wire connection seat 29, and the drone hanging clamp 8 is hingedly installed on the wire clamp hook 7 and is located on the hook body opening side away from the wire clamp hook 7. The opening of the hook body of the wire clamp hook 7 is also rotatably installed with a gravity locking member 30, and the gravity locking member 30 is formed with a locking plate 31 at the hook body opening, and arc-shaped touch plates 32 that can contact the wire are formed on both sides of the hook body. In this embodiment, the weight of the two arc-shaped touch plates 32 of the gravity locking member 30 is designed to be greater than the weight of the locking plate 31, so that the gravity locking member 30 is in an unlocked state under normal conditions, the locking plate 31 swings outward, and an opening is formed at the wire clamp hook 7; when the wire enters the wire clamp hook 7 and contacts the arc-shaped touch plate 32, the locking plate 31 swings inward to close the opening of the wire clamp hook 7, so that the gravity locking member 30 cooperates with the wire clamp hook 7 to form a locked state.

[0061] Further, as a preferred technical solution of this embodiment, in order to reduce the difficulty of controlling the drone 1, the following structure of the pylon 3 is adopted in this embodiment; Figure 3 and Figure 4 As shown, the pylon 3 includes a group of herringbone guide frames 12, which are arranged at intervals and connected by a pylon crossbar 13; the pylon crossbar 13 is provided with a U-shaped wire clamp pylon 14 between the group of herringbone guide frames 12. Through the group of herringbone guide frames 12, the pylon 3 can be hung on the wire, reducing the weight of the grounding wire clamp and the grounding wire 10 affecting the control difficulty of the drone 1; the U-shaped wire clamp pylon 14 is used to hang the drone clamp 8 of the grounding wire clamp, and when the pylon 3 is hung on the wire, the wire clamp hook 7 of the grounding wire clamp is quickly hung on the electric test ring 9.

[0062] Furthermore, as a preferred technical solution of this embodiment, considering that the drone 1 is working at high altitude, the precise assembly and disassembly of the A-phase grounding clamp 4, the B-phase grounding clamp 5 and the C-phase grounding clamp 6 cannot be accurately controlled by the naked eye; therefore, Figure 3 and Figure 4 As shown, in this embodiment, a camera 27 is installed on one side of the clamp control box 15 of the A-phase grounding clamp 4, the B-phase grounding clamp 5 and the C-phase grounding clamp 6 through a camera bracket. The camera 27 is connected to the signal receiving and sending device 26 through the circuit board 17. The scene captured by the camera 27 is transmitted to the remote control 33 in real time through the signal receiving and sending device 26, so as to more accurately obtain the position of the test ring 9 of the A-phase grounding wire, the B-phase grounding wire and the C-phase grounding wire, and observe the installation and disassembly status.

[0063] In addition, in order to avoid the A-phase grounding clamp 4, the B-phase grounding clamp 5 and the C-phase grounding clamp 6 being unable to be taken away when a problem occurs in the device; therefore, if Figure 3 and Figure 4As shown, in this embodiment, the wire clamp hook 7 is also provided with an operating rod connecting hole 25 for the insulating operating rod to pass through; in case of an accident, the grounding wire clamp can be hung and taken out through the insulating operating rod and the operating rod connecting hole 25.

[0064] Based on the above-mentioned intelligent grounding device dedicated to drones, this embodiment also proposes a method for installing a drone grounding device, which includes the following steps:

[0065] Step 1. After the A-phase grounding wire clamp, the B-phase grounding wire clamp and the C-phase grounding wire clamp are all connected to the grounding wire, short-circuit the tail end of the three-phase grounding wire to the grounding pin, and then insert the grounding pin into the ground.

[0066] Step 2: Confirm that the drone, ladder, bracket, A-phase grounding clamp, B-phase grounding clamp, C-phase grounding clamp and auxiliary load-bearing equipment are in good condition, and check whether the battery power and signal receiving and sending device are normal;

[0067] Step 3, control the drone to take off until the ladder and the bracket on the ladder are at a certain height off the ground to meet the requirements of the mounting of the A-phase grounding wire clamp; mount the A-phase grounding wire clamp on the bracket through the drone mounting clamp, and connect the grounding wire to the wire clamp hook of the A-phase grounding wire clamp;

[0068] Step 4, control the drone to fly to the test ring of the A-phase conductor, observe the position of the test ring through the camera, control the drone to fly so that the test ring of the A-phase conductor enters the wire clamp hook of the A-phase grounding wire clamp, and control the push rod motor of the A-phase grounding wire clamp to start through the remote control, so that the guide rod drives the clamp block to cooperate with the wire clamp hook to clamp the test ring of the A-phase conductor; then control the drone to fly back and land;

[0069] Step 5, repeat steps 2 and 3 to install the C-phase grounding clamp on the test ring of the C-phase conductor;

[0070] Step 6, when installing the B-phase grounding wire with the highest height from the ground, control the first drone to take off until the soft ladder and the bracket on the soft ladder are at a certain height off the ground to meet the mounting requirements of the B-phase grounding wire clamp; mount the B-phase grounding wire clamp on the bracket through the drone mounting clamp, and connect the grounding wire with the wire clamp hook of the B-phase grounding wire clamp; at this time, control the second drone to take off until the soft ladder and the bracket on the soft ladder are at a certain height off the ground to meet the mounting requirements of the auxiliary load-bearing wire clamp; mount the auxiliary load-bearing wire clamp on the bracket through the drone mounting clamp, and connect the grounding wire with the grounding wire connection socket of the auxiliary load-bearing wire clamp;

[0071] Step 7, control the two drones to rise in flight altitude between the A-phase conductor and the C-phase conductor, until the drone equipped with the B-phase grounding wire clamp flies to the test ring of the B-phase conductor, and the drone equipped with the auxiliary load-bearing wire clamp flies to the A-phase conductor or the C-phase conductor; control the first drone to fly so that the test ring of the B-phase conductor enters the wire clamp hook of the B-phase grounding wire clamp, and control the push rod motor of the B-phase grounding wire clamp to start through the remote control, so that the guide rod drives the clamp block to cooperate with the wire clamp hook to clamp the test ring of the B-phase conductor; control the second drone to fly so that the A-phase conductor or the C-phase conductor enters the wire clamp hook of the auxiliary load-bearing wire clamp; control the two drones to descend in flight altitude so that the A-phase conductor or the C-phase conductor contacts the arc-shaped touch plate of the gravity locking component, so that the gravity locking component cooperates with the wire clamp hook to form a locked state; then control the two drones to fly back and land to complete the grounding device installation operation.

[0072] Based on the above-mentioned intelligent grounding device dedicated to drones, this embodiment also proposes a method for disassembling the drone grounding device, which includes the following steps:

[0073] Step I: Confirm that the drone, ladder, bracket, A-phase grounding clamp, B-phase grounding clamp, and C-phase grounding clamp are intact, and check whether the battery power and signal receiving and sending device are normal;

[0074] Step II, control the two drones to rise between the A-phase wire and the C-phase wire to the test ring of the B-phase wire and the A-phase wire or the C-phase wire; control the first drone to fly so that the drone hanging clamp of the B-phase grounding wire clamp is mounted on the rack, and control the push rod motor of the A-phase grounding wire clamp to start through the remote control, so that the guide rod drives the clamp block to loosen the test ring of the B-phase wire; control the second drone to fly so that the drone hanging clamp of the auxiliary load-bearing wire clamp is mounted on the rack; then control the two drones to rise in flight height so that the A-phase wire or the C-phase wire is out of contact with the arc-shaped touch plate of the gravity locking member, and the arc-shaped touch plate swings to form an unlocked state; then control the two drones to rise in flight height so that the test ring of the B-phase wire is disengaged from the wire clamp hook of the B-phase grounding wire clamp, and at the same time, the A-phase wire or the C-phase wire can be disengaged from the wire clamp hook of the auxiliary load-bearing wire clamp;

[0075] Step III, control the drone to descend its flight altitude, remove the B-phase grounding wire clamp and the auxiliary load-bearing wire clamp from the hanging bracket of the soft ladder, and remove the grounding wire;

[0076] Step IV, control the drone to fly to the test ring of the A-phase conductor, control the drone to fly so that the drone hanging clip of the A-phase grounding wire clamp is hung on the hanging bracket; control the push rod motor of the A-phase grounding wire clamp to start by the remote controller, so that the guide rod drives the clamp block to release the test ring of the A-phase conductor; then control the drone to rise in flight altitude, so that the test ring of the A-phase conductor is released from the wire clamp hook of the A-phase grounding wire clamp;

[0077] Step V, control the drone to descend its flight altitude, remove the A-phase grounding wire clamp from the hanging bracket of the soft ladder, and remove the grounding wire;

[0078] Step VI, repeating steps IV and V to remove the C-phase grounding wire clamp from the test ring of the C-phase conductor;

[0079] Step VII, store and organize the drone, A-phase grounding wire clamp, B-phase grounding wire clamp, C-phase grounding wire clamp, grounding wire and grounding pin to complete the disassembly of the grounding device.

[0080] In the above-mentioned drone grounding device installation and disassembly method, for the installation and disassembly of the A-phase grounding wire and the C-phase grounding wire, since the wires are located on both sides and are relatively low, a single drone with a grounding wire clamp can be used to complete the installation and disassembly of the grounding wire. For the installation and disassembly of the B-phase grounding wire, since the B-phase wire is located in the middle and is relatively high, and the grounding wire is long and heavy, a dual drone operation method is used, and the B-phase grounding wire clamp is used in conjunction with an auxiliary load-bearing wire clamp to reduce the load of a single drone, so that the installation and disassembly of the B-phase grounding wire can be completed stably and efficiently.

[0081] In summary, the A-phase grounding wire clamp, B-phase grounding wire clamp and C-phase grounding wire clamp of the drone-specific intelligent grounding device are all installed and removed by the drone in conjunction with a soft ladder and a bracket; the A-phase grounding wire clamp, B-phase grounding wire clamp and C-phase grounding wire clamp are all connected to grounding wires, and the ends of the three sets of grounding wires are connected to the same grounding pin through a three-phase-in-one short-circuit point. The drone-specific intelligent grounding device can improve the efficiency of hanging and removing grounding wires during power outage and maintenance operations, while reducing operational risks and alleviating the workload of staff.

Any changes made to the above embodiments based on the ideas and technical essence of the present invention are within the protection scope of the present invention.
