Description

Technical Field

[0001] The present invention relates to the technical field of power grounding wires, and in particular to a grounding wire disassembling and hanging device based on an unmanned aerial vehicle (UAV). Background Art

[0002] Transmission lines are distributed at many points and over a wide area, with complex terrain and harsh natural environments. Power lines and tower accessories are exposed to the outdoors for a long time and are affected by continuous mechanical tension, electrical flashover, and material aging, resulting in damage such as broken strands, wear, and corrosion. If not repaired and replaced in time, originally minor damages and defects may expand, ultimately leading to serious accidents and large-scale power outages. Therefore, transmission lines must be regularly inspected to prevent accidents and ensure power supply safety. The grounding wire is the basic safety guarantee for personnel and inspection operations. To facilitate high-altitude operations, currently, it is mostly assisted by flying tools.

[0003] For example, Chinese Patent "CN113937519B" discloses "a method for disassembling and hanging a grounding wire at high altitude based on an unmanned aerial vehicle". Through two spring clip pieces for clamping the wire arranged inside the hook body, when the UAV drops the wire clip on the transmission wire, the ground operator pulls the insulating rope, causing the spring clip pieces to be compressed, and the transmission wire is clamped into the double-tongue wire clip. At the same time, the hook body locking device is controlled, and a signal is sent to the first wireless communication module. The first wireless communication module sends an electrical signal to the first MCU. After receiving the signal, the first MCU sends a locking signal to the first through-type lead screw motor, and the lead screw of the first through-type lead screw motor extends to lock the hook body of the double-tongue wire clip, preventing the transmission wire from falling off, and the remote grounding wire hanging can be completed on the ground, greatly reducing the labor intensity of the operation. However, although the spring clip pieces can stably fix the transmission line inside the wire clip, due to the certain elastic force of the spring clip pieces, manual assistance is required to apply a force to make the transmission wire overcome the elastic force of the spring clip pieces and enter the wire clip. At the same time, the requirements for the UAV during disassembly are relatively high, and in order to ensure stability, a hook body locking device is also required, with a relatively complex structure and high later maintenance costs. Summary of the Invention

The mounting pin is rotatably arranged on the hanging part;

[0008] Adjusting rope, the adjusting part is provided with a first mounting rod, and both ends of the adjusting rope are respectively connected to the first mounting rods of the two adjusting parts.

[0019] In this solution, by installing the ground wire on the installation part of the hook, the ground wire and the hook are integrated, and the adjusting rope of the hanging part is connected to the drone. When the drone takes off, the drone first transmits the lifting force to the adjusting rope, and the adjusting rope pulls the adjusting part of the fixing part, so that the adjusting part moves upward with the installation pin as the axis, and then the fixing part moves downward to open the channel of the hanging part, facilitating the direct entry of the power transmission line into the channel. After entering, through the hook under the drone, the hanging part is hung on the power transmission line, and gradually contacts the pulling force on the adjusting rope, so that the fixing part of the fixing part swings back, limiting the power transmission line in the channel to achieve fixation. There is no need to apply additional pulling force to the hook, reducing the labor input, avoiding damage to the power transmission line, and at the same time reducing the cost of the entire device. It not only simplifies the overall structure but also reduces the later maintenance cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the present invention will be further described below with reference to the drawings and embodiments.

[0028] As Figures 1 to 6As shown in the figure, an embodiment of the present invention provides a device for attaching and detaching a grounding wire based on a drone, which is connected between a power transmission line 5 and a ground wire 6, and includes:

[0029] A hook, which includes a hanging part 1 and a mounting part 2 connected to the hanging part 1. The hanging part 1 has a channel 105 for accommodating the power transmission line 5, and the mounting part 2 is connected to the ground wire 6;

[0030] Two fixing members 4, which are mirror-symmetrically distributed on the hanging part 1. The fixing member 4 includes a fixing part 401 corresponding to the channel 105, an adjusting part 403 connected to the fixing part 401, and a mounting pin 402 connected between the fixing part 401 and the adjusting part 403. The mounting pin 402 is rotatably arranged on the hanging part 1;

[0031] An adjusting rope 3, the adjusting part 403 is provided with a first mounting rod 404, and both ends of the adjusting rope 3 are respectively connected to the first mounting rods 404 of the two adjusting parts 403. When the adjusting rope 3 is pulled by an external force, the adjusting part 403 drives the fixing part 401 to rotate around the mounting pin 402 to open the channel 105.

[0032] In the embodiment of the present invention, during the processing of the fixing member 4, the weight of the adjusting part 403 is greater than that of the fixing part 401. Therefore, in the initial state, on the premise of taking the mounting pin 402 as the fulcrum, the adjusting part 403 will press downwards to lift the fixing part 401 upwards, and the fixing parts 401 of the two fixing members 4 abut against each other to close the channel 105 of the hanging part 1.

[0033] During the assembly stage, both ends of the adjusting rope 3 are respectively tied to the first mounting rods 404 of the two adjusting parts 403, and a suspension structure, such as a sling, is arranged on the bottom frame of the drone. The suspension structure on the bottom frame of the drone is installed on the adjusting rope 3. Then, the ground wire 6 to be grounded is installed on the mounting part 2 of the hook and grounded. Then, the drone is controlled to take off, so that the drone preferentially pulls the adjusting rope 3, making the adjusting rope 3 gradually straightened. After being straightened, the acting force brought by the drone is transmitted to the adjusting part 403, making the adjusting part 403 move upwards around the mounting pin 402. Furthermore, the fixing part 401 moves downwards around the mounting pin 402 to expand the channel 105 of the hanging part 1 until the drone ascends and moves the hanging part 1 to the position of the power transmission line 5, so that the power transmission line 5 is at the opening of the channel 105. At this time, the drone is gradually lowered, so that the hanging part 1 is hung on the power transmission line 5, and the weight of the hook is borne by the power transmission line 5. Since the adjusting rope 3 is still in a straightened state, the drone is continuously and slowly lowered, so that the fixing parts 401 of the two fixing members 4 automatically swing into the channel 105 under the action of gravity, surround the power transmission line 5 in the channel 105, and implement fixation to ensure the stability of the hanging part 1 on the power transmission line 5 and complete grounding.

[0034] After the construction operation of the transmission line 5 is completed, the drone is also taken off, so that the suspension structure of the drone is connected to the adjustment rope 3 again. The connection method can be the connection hook structure on the suspension structure. The connection between the suspension structure and the adjustment rope 3 is completed through the drone camera. After the connection, the drone is raised, so that the drone exerts a force on the adjustment rope 3, so that both ends of the adjustment rope 3 pull the adjustment parts 403 of the two fixing parts 4, and then the fixing part 401 rotates around the mounting pin 402 to open the channel 105. During the continuous ascent of the drone, the hook can be easily separated from the transmission line 5. Only by operating the ascent and descent of the drone can the installation and disassembly of the hook be completed. The operation is convenient and fast, no additional pulling force needs to be applied to the hook, which reduces the labor input, avoids damage to the transmission line 5, and reduces the cost of the entire device. It not only simplifies the overall structure, but also reduces the later maintenance cost of the equipment.

[0035] Before grounding the line, it is necessary to first confirm whether the line is energized to avoid potential safety hazards of electric shock. For this purpose, a non-contact voltage detection method can be used to determine whether the line is energized. For example, a magnetic field sensor is carried on the drone and installed at the bottom or side of the drone so that it can accurately detect the magnetic field intensity when approaching the wire. The voltage detection result can be transmitted to the ground working terminal in real time through a wireless communication module (such as 4G / 5G, Wi-Fi) for the operator to analyze and make decisions.

[0036] The magnetic field sensor (such as Honeywell HMC5883L, Bartington Mag-03) determines whether the wire is energized by detecting the magnetic field intensity around the wire. Such sensors can be applied to transmission lines with different voltage levels (such as 1 kV to 110 kV and above). If it is detected that the wire is energized, the operator can first take power-off measures to ensure the safety of the line, and then control the drone to install the hook on the transmission line; if it is detected that the wire is not energized, the operator can directly control the drone to complete the hanging operation of the grounding wire.

[0037] It should be noted that the combined use of magnetic field sensors, drones, wireless communication technologies, etc. are all mature existing technologies and can be directly applied to the voltage detection task. This non-contact voltage detection method not only improves the safety of operation, but also significantly improves the voltage detection efficiency, and is especially suitable for the operation and maintenance of high-voltage transmission lines.

[0038] Specifically, such as Figure 2 And Figure 6As shown, the hanging part 1 is provided with a fixing pin 101, the adjusting part 403 is provided with a second mounting rod 405, and a tension spring 7 is provided between the second mounting rod 405 and the fixing pin 101; due to the existence of the tension spring 7, the adjusting part 403 is always subjected to the tension of the tension spring 7 and swings downward, and the weight ratio of the adjusting part 403 to the fixing part 401 does not need to be controlled. In the initial state, the adjusting part 403 is always subjected to the tension of the tension spring 7 and the fixing part 401 is placed in the channel 105 position. When the fixing part 401 is closed, the stability of the transmission line 5 in the channel 105 is guaranteed. The wire 5 sways under the action of wind force, but the elastic force of the tension spring 7 can still ensure the stability of the transmission line 5 in the channel 105. Under the support of the tension spring 7, when the drone takes off, the drone pulls the adjustment rope 3 upward, and the hook falls downward due to gravity, so that the adjustment rope 3 pulls the adjustment part 403 of the fixing part 4 and stretches the tension spring 7. After reaching the specified position, the drone is continuously lowered, so that the hanging part 1 can be hung on the transmission line 5, and the tension spring 7 drives the fixing part 4 to reset, so as to clamp the transmission line 5 and ensure stability. When the hanging part 1 is disassembled, the drone is continuously raised, so that the two fixing parts 4 are opened first, and then the hook is separated from the transmission line 5, which is more convenient to operate and has a simple structure.

[0039] Specifically, Figure 4 As shown, a fixing portion 401 of one fixing member 4 is provided with a slot 406, and a fixing portion 401 of another fixing member 4 is provided with a block 407, and the block 407 is engaged with the slot 406; with the cooperation of the slot 406 and the block 407, when the two fixing members 4 are closed, the block 407 on one fixing member 4 will be embedded in the slot 406 on the other fixing member 4, so that the channel 105 can evenly wrap the power transmission line 5, thereby ensuring the stability of the power transmission line 5 in the channel 105 and preventing it from detaching.

[0040] Specifically, Figure 6 As shown, the hanging part 1 is provided with a limit block 102, and the limit block 102 corresponds to the adjusting part 403; under the setting of the limit block 102, the maximum angle of rotation of the adjusting part 403 around the mounting pin 402 is effectively limited, ensuring that the fixing part 401 completely leaves the channel 105 so that the power transmission line 5 can enter smoothly without being stuck, and it can also prevent the tension spring 7 from being damaged by excessive stretching, thereby extending the service life of the tension spring 7 and reducing maintenance requirements.

[0041] Specifically, Figure 6As shown in the figure, U-shaped frames 103 are provided on both sides of the hanging part 1, and the adjusting rope 3 is threaded between the two U-shaped frames 103. Under the action of the U-shaped frames 103, when assembling the adjusting rope 3, the two ends of the adjusting rope 3 are respectively passed through the corresponding U-shaped frames 103 to be connected to the corresponding first mounting rod 404. During the use of the adjusting rope 3, the U-shaped frames 103 can guide and fix the path of the adjusting rope 3, which can not only ensure that it moves along a predetermined route when pulled, but also fix the adjusting rope 3 at a specified position, providing convenience for the high-altitude connection of the adjusting rope 3 of the drone.

[0042] At the same time, two limiting wheels 104 are rotatably provided in the U-shaped frame 103, and the adjusting rope 3 is located between the two limiting wheels 104. The limiting wheels 104 have annular grooves, and the adjusting rope 3 is located in the grooves of the limiting wheels 104, which can realize the limitation of the adjusting rope 3. It can not only accurately guide the path of the adjusting rope 3 to ensure that it always moves along a predetermined direction, but also significantly reduce the direct friction between the adjusting rope 3 and the U-shaped frame 103 and the hanging part 1, thereby reducing wear, ensuring that the pulling force can be transmitted more efficiently, and extending the service life of the adjusting rope 3.

[0043] Specifically, as Figure 5 shown, the adjusting rope 3 includes two connecting ropes 301 respectively connected to the two first mounting rods 404 and a connecting rod 302 connected between the two connecting ropes 301. The connecting rod 302 has a V-shaped structure; the connecting rod 302 is made of a rigid material, such as silica gel. The V-shaped connecting rod 302 can effectively distribute the external force evenly to the two connecting ropes 301, avoiding unstable operation caused by uneven unilateral force, and the V-shaped connecting rod 302 also facilitates the connection of the connecting ropes 301 to the suspension structure of the drone.

[0044] Secondly, a stop block 303 is fixedly provided at the end of the connecting rod 302, and the stop block 303 abuts against one side of the U-shaped frame 103; the connecting rod 302 can be limited by the stop block 303 to ensure that the connecting rod 302 is always at the top of the hanging part 1. When disassembling the device from the transmission line 5, it is convenient for the drone to dock to lift and remove the hanging part 1.

[0045] Specifically, as Figure 2 shown, the mounting part 2 includes an inclined section 201 connected to the hanging part 1 at an angle and a vertical section 202 connected to the inclined section 201. The vertical section 202 is connected to the ground wire 6; the position of the vertical section 202 corresponds to the center of gravity position of the hook. When the ground wire 6 is connected to the vertical section 202 and the drone is lifted, it is ensured that the hook will not swing in the air, thereby improving the stability of the drone during transportation.

[0046] At the same time, as Figure 3As shown, the vertical section 202 is provided with a mounting hole 203, and the ground wire 6 is passed through the mounting hole 203. The vertical section 202 is threadedly connected with a mounting bolt 204. The mounting bolt 204 penetrates into the interior of the mounting hole 203 and abuts against the ground wire 6. In order to more conveniently install the ground wire 6, the ground wire 6 is directly passed through the mounting hole 203, and finally the mounting bolt 204 is tightened. The mounting bolt 204 directly abuts against and fastens the ground wire 6, ensuring a firm connection between the ground wire 6 and the device. By means of threading, a continuous clamping force is provided, and it can remain stable even under the action of vibration or wind, avoiding potential safety hazards caused by loosening.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
