Description

Technical Field

[0001] The present invention relates to the technical field of grounding wire hanging, and in particular to an auxiliary grounding hanging device for an unmanned aerial vehicle platform. Background Art

[0002] In the electric power industry, the transmission and distribution lines play the role of transmitting the electricity generated by the transmission and distribution plants to the homes of electricity users, factories, schools and public places. It can be seen that the stable operation of the transmission and distribution lines is of great significance to the normal electricity demand of the homes of electricity users, factories, schools and public places. Therefore, maintenance workers will regularly inspect and maintain the transmission and distribution lines. During the inspection and maintenance of the transmission and distribution lines, it is generally necessary to hang a grounding wire or multiple grounding wires on the transmission and distribution lines under maintenance. In this way, the transmission and distribution lines are connected to the earth to form an equipotential body, avoiding electric shock due to leakage of the transmission and distribution lines, thereby ensuring the personal safety of the personnel of the transmission and distribution lines.

[0003] When the ground wire is currently hung on the transmission and distribution line, for low-altitude transmission and distribution lines, the maintenance personnel carrying the ground wire are generally lifted to a position close to the transmission and distribution line by an electric lifting device, and then the ground wire is hung on the transmission and distribution line; for high-altitude transmission and distribution lines or transmission and distribution lines across large rivers, highways and river valleys, the maintenance personnel carrying the ground wire generally climb up the tower to the top of the tower, and then hang the ground wire on the transmission and distribution line to complete the process of hanging the ground wire on the transmission and distribution line. Although the ground wire can be hung on the transmission and distribution line by using an electric lifting device or by the maintenance personnel climbing up the tower to the top of the tower to hang the ground wire on the transmission and distribution line, the following defects still exist in daily use: 2. Maintenance personnel climb up the tower to the top of the tower to connect the ground wire to the transmission and distribution line. This not only poses a risk of falling from a height, but may also cause electric shock accidents due to direct contact with live equipment. Due to the complex terrain and environmental restrictions (such as uneven terrain or numerous trees), the method of connecting the ground wire to the transmission and distribution line by using an electric lifting device or the maintenance personnel climbing to the top of the tower to connect the ground wire to the transmission and distribution line is not only inefficient but also poses safety risks. Moreover, these operations require the operators to work under harsh conditions, which increases the labor intensity of the maintenance personnel.

[0004] Therefore, it is necessary to optimize and improve the traditional structure and method for hanging conductors in order to solve the problem of low efficiency and safety risks caused by relying on manual climbing to hang grounding wires when the transmission and distribution lines need to be hung and grounded during maintenance of the transmission and distribution lines.

DETAILED DESCRIPTION

[0029] like Figure 1-8 In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, the terms "upper", "lower", "left", "right" and other directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning. Example

[0032] When the ground wire is currently hung on the transmission and distribution line, it is generally hung on the transmission and distribution line by an electric lifting device or by maintenance personnel climbing up the tower to the top of the tower to hang the ground wire on the transmission and distribution line. However, in daily use, there are still the following defects: (1) Maintenance personnel climb up the tower to the top of the tower to connect the ground wire to the transmission and distribution line. This not only poses a risk of falling from a height, but may also cause electric shock accidents due to direct contact with live equipment. (2) Due to complex terrain and environmental restrictions (such as uneven terrain or numerous trees), the method of connecting the ground wire to the transmission and distribution line by using an electric lifting device or the method of maintenance personnel climbing to the top of the tower to connect the ground wire to the transmission and distribution line is not only inefficient but also poses safety risks. In addition, these operations require operators to work under harsh conditions, which increases the labor intensity of maintenance personnel.

[0033] Therefore, the present application proposes an auxiliary grounding and hanging device for a UAV platform to solve the problem of low efficiency and safety risks in hanging grounding wires caused by relying on manual climbing to hang grounding wires when the power transmission and distribution lines need to be hung and grounded during the maintenance of the power transmission and distribution lines.

[0034] For details, please refer to Figure 1 and Figure 2, an auxiliary grounding hanging device for an unmanned aerial vehicle platform comprises a hanging base 1, a fixed wire clamp hook 2, a movable wire clamp hook 3, a movable wire clamp hook driving assembly 4, a grounding wire connector 5 and a hanging hanger 6; the outer wall of the hanging base 1 is threadedly connected with the grounding wire connector 5, and the hanging base 1 is provided with a movable wire clamp hook driving assembly 4, the movable wire clamp hook driving assembly 4 communicates with the wireless remote control through a controller, the movable end of the movable wire clamp hook driving assembly 4 passes through a through hole 7 at the top of the hanging base 1 and is hinged with the end of the movable wire clamp hook 3, the middle part of the movable wire clamp hook 3 is connected to the side wall of the fixed wire clamp hook 2 through a pin shaft 8, the fixed end of the fixed wire clamp hook 2 is connected to the top of the hanging base 1, the top of the fixed wire clamp hook 2 is connected to the outer wall of the hanging hanger 6, and the hanging hanger 6 is hung with a hook connected to the hanging rope at the bottom of the unmanned aerial vehicle.

[0035] In actual use, when the auxiliary grounding hanging device of the UAV platform is hung on the power transmission and distribution line, the other end of the grounding wire grounded to the ground is first hung or wound on the grounding wire connector 5, and then the hook connected to the bottom of the UAV by the hanging rope is hung with the hanging hanger 6, and then the UAV is remotely controlled to fly the auxiliary grounding hanging device of the UAV platform to the vicinity of the power transmission and distribution line to be repaired, and the power transmission and distribution line is made to enter the power transmission and distribution line clamping area defined by the fixed wire clamp hook 2 and the movable wire clamp hook 3 from the opening between the fixed wire clamp hook 2 and the movable wire clamp hook 3, and then the wireless remote control is used to control the movable wire clamp hook drive component 4 to move, and the moving movable wire clamp hook drive component 4 drives the movable wire clamp hook 3 to move toward the fixed wire clamp hook 2, so that the opening between the fixed wire clamp hook 2 and the movable wire clamp hook 3 is closed, and the power transmission and distribution line is restricted to the power transmission and distribution line clamping area defined by the fixed wire clamp hook 2 and the movable wire clamp hook 3, so that the grounding wire is hung on the power transmission and distribution line to be repaired; When the auxiliary grounding hanging device of the UAV platform is detached from the power transmission and distribution line, first use the wireless remote control to control the movable wire clamp hook driving component 4 to operate, and the operating movable wire clamp hook driving component 4 will drive the movable wire clamp hook 3 to move toward the fixed wire clamp hook 2, and the opening between the fixed wire clamp hook 2 and the movable wire clamp hook 3 will open. At this time, the UAV remote control is used to control the UAV to fly away from the power transmission and distribution line, which indirectly makes the auxiliary grounding hanging device of the UAV platform fly away from the power transmission and distribution line to be inspected, and the power transmission and distribution line in the power transmission and distribution line clamping area will be detached from the opening opened between the fixed wire clamp hook 2 and the movable wire clamp hook 3. Then, the UAV carries the auxiliary grounding hanging device of the UAV platform to fly to the ground and stops, so that the grounding wire is removed from the power transmission and distribution line.

[0036] In this way, the grounding wire can be hung on the transmission and distribution line or the hung grounding wire can be removed from the transmission and distribution line through the auxiliary grounding hanging device of the drone platform. There is no need to use the electric lifting device to hang the grounding wire on the transmission and distribution line or the maintenance personnel can hang the grounding wire on the transmission and distribution line by climbing to the top of the tower along the iron tower. This solves the problem of low efficiency and safety risks in hanging grounding wires caused by relying on manual climbing to hang grounding wires when the transmission and distribution lines need to be hung for grounding during maintenance of the transmission and distribution lines.

[0037] It should be noted that the UAV is a UAV with a camera, and the camera end is facing the UAV platform auxiliary grounding hanging device under the UAV to record the process of the UAV platform auxiliary grounding hanging device being connected to the power transmission and distribution line or the UAV platform auxiliary grounding hanging device being detached from the power transmission and distribution line, and then the recorded image information is wirelessly sent to the display interface of the UAV remote control used to control the flight of the UAV, so that maintenance personnel can understand through the display interface whether the UAV platform auxiliary grounding hanging device is connected to the power transmission and distribution line or the UAV platform auxiliary grounding hanging device is detached from the power transmission and distribution line, and then fine-tune the UAV so that the UAV platform auxiliary grounding hanging device can be connected to the power transmission and distribution line in a short time or the UAV platform auxiliary grounding hanging device can be detached from the power transmission and distribution line in a short time.

[0038] See also Figure 1 and Figure 3 The movable wire clamp hook driving assembly 4 for driving the movable wire clamp hook includes an electromagnet block 10, an iron block 9 and a linkage part 11; wherein the electromagnet block 10 generates magnetism when energized or loses magnetism when de-energized, so that the iron block 9 moves downward and magnetically combines with the electromagnet block 10 or moves upward and separates from the electromagnet block 10, indirectly driving the linkage part 11 connected to the iron block 9 to drive the movable wire clamp hook 3 to approach or move away from the fixed wire clamp hook 2, thereby completing the closing and opening of the opening between the fixed wire clamp hook 2 and the movable wire clamp hook 3.

[0039] Specifically, the switch of the electromagnet block 9 for powering on / off communicates with the wireless remote control through the controller. The electromagnet block 10 is fixedly arranged in the rectangular cavity 12 inside the hanging base 1. The electromagnet block 10 is located directly below the iron block 9 that is slidably connected to the rectangular cavity 12. One end of the iron block 9 is connected to one end of the linkage member 11. The linkage end of the linkage member 11 passes through the through hole 7 at the top of the hanging base 1 and is connected to the end of the movable wire clamp hook 3.

[0040] In actual use, when the UAV platform auxiliary grounding hanging device is delivered to the power transmission and distribution line where the grounding wire needs to be hung with the aid of a UAV, the power transmission and distribution line is firstly made to enter the power transmission and distribution line clamping area defined by the fixed wire clamp hook 2 and the movable wire clamp hook 3 from the opening between the fixed wire clamp hook 2 and the movable wire clamp hook 3, and then the wireless remote control is operated to control the power on / off switch of the electromagnet block 9 through the controller to close, so that the electromagnet block 10 is energized to generate magnetism. At this time, the iron block 9 is affected by the magnetic force of the electromagnet block 10, and the iron block 9 moves down along the rectangular cavity 12 and is magnetically coupled with the electromagnet block 10. The moving iron block 9 continues to drive the movable wire clamp hook 3 to move toward the fixed wire clamp hook 2 through the linkage 11, and the fixed wire clamp hook 2 and the movable wire clamp hook 3 define a closed hanging area 26 for clamping the wire. After the inspection and maintenance of the power transmission and distribution lines is completed, when the auxiliary grounding hanging device of the UAV platform needs to be detached from the power transmission and distribution lines, the wireless remote control can be operated to control the switch of the electromagnet block 9 to be powered on / off through the controller to disconnect, so that the electromagnet block 10 loses power and loses magnetism, and the iron block 9 moves up along the rectangular cavity 12 under the influence of the weight of the movable wire clamp hook 3 and separates from the electromagnet block 10. The upward iron block 9 drives the movable wire clamp hook 3 to move away from the fixed wire clamp hook 2 through the linkage part 11. The fixed wire clamp hook 2 and the movable wire clamp hook 3 define an opening and closing hanging area for disengaging the wire. Then, the UAV is controlled by the UAV remote control to fly away from the power transmission and distribution lines, which indirectly makes the auxiliary grounding hanging device of the UAV platform fly away from the power transmission and distribution lines to be inspected, and the power transmission and distribution lines in the clamping area of ​​the power transmission and distribution lines are disengaged from the opening opened between the fixed wire clamp hook 2 and the movable wire clamp hook 3.

[0041] It should be noted that the electromagnet block 10 is a prior art and has not been improved or designed, so its structure will not be described in detail.

[0042] It should be noted that the wireless remote control communication is an existing technology and has not been improved or designed, so its structure will not be described in detail.

[0043] It should be noted that the rectangular cavity 12 is communicated with the through hole 7 on the top of the hanging base 1 .

[0044] See also Figure 1 and Figure 3 In order to prevent the iron block 9 from moving out of the magnetic action area of ​​the electromagnet block 10 and the iron block 9 along the rectangular cavity 12, a limit block 13 is provided on the inner wall of the rectangular cavity 12 to limit the iron block 9 from moving out of the magnetic action area of ​​the electromagnet block 10 and the iron block 9.

[0045] In actual use, when the electromagnet block 10 does not generate magnetism and the iron block 9 moves upward along the rectangular cavity 12 under the influence of the overall weight of the movable wire clamp hook 3, the limit block 13 arranged on the inner wall of the rectangular cavity 12 will prevent the iron block 9 from continuing to move upward, thereby preventing the iron block 9 from moving out of the magnetic action area of ​​the electromagnet block 10 and the iron block 9.

[0046] It should be noted that when the electromagnet block 10 loses its magnetism when the power is off, the electromagnet block 10 separates from the iron block 9. Under the influence of the weight of the movable wire clamp hook 3, the iron block 9 moves up along the rectangular cavity 12 to the limit block 13. The limit block 13 will not restrict the upward movement of the iron block 9, so that the area defined between the fixed wire clamp hook 2 and the movable wire clamp hook 3 cannot be in an open or closed state.

[0047] See also Figure 1 and Figure 5 The linkage member 11 for linking the movable wire clamp hook 3 includes a linkage rod 14 and a linkage shaft 15; wherein the linkage rod 14 is used to connect the iron block 9 with the linkage shaft 15; and the linkage shaft 15 is used to connect the linkage rod 14 with the movable wire clamp hook 3.

[0048] Specifically, one end of the linkage rod 14 is connected to one end of the iron block 9, and the other end of the linkage rod 14 passes through the through hole 7 at the top of the hanging base 1 and is connected to the middle of the linkage shaft 15, and both ends of the linkage shaft 15 are respectively connected to the ends of the movable wire clamp hook 3.

[0049] In actual use, when the iron block 9 is magnetically coupled to the electromagnet block 10 and moves downward along the rectangular cavity 12, the iron block 9 drives the movable wire clamp hook 3 to approach the fixed wire clamp hook 2 through the linkage rod 14 and the linkage shaft 15 connected to the linkage rod 14, so that a closed hanging area for hanging the power transmission and distribution lines is defined between the movable wire clamp hook 3 and the fixed wire clamp hook 2; the electromagnet block 10 does not generate magnetism, and under the influence of the overall weight of the movable wire clamp hook 3, when the iron block 9 moves upward along the rectangular cavity 12, the iron block 9 drives the movable wire clamp hook 3 to move away from the fixed wire clamp hook 2 through the linkage rod 14 and the linkage shaft 15 connected to the linkage rod 14, so that an open and closed hanging area for hanging the power transmission and distribution lines is defined between the movable wire clamp hook 3 and the fixed wire clamp hook 2.

[0050] It should be noted that the linkage rod 14 is located in the rectangular cavity 12 , and the linkage rod 14 is slidably fitted with the through hole 7 on the top of the hanging base 1 .

[0051] It should be noted that the rectangular cavity 12 is a rectangular cavity groove.

[0052] See also Figure 3 , which are used in conjunction with the fixed wire clamp hook 2 for clamping include a first movable wire clamp arm 16 and a second movable wire clamp arm 17; wherein the first movable wire clamp arm 16 and the second movable wire clamp arm 17 are both used to define a clamping area for partially clamping the power transmission and distribution wires.

[0053] Specifically, the limiting notches 18 at one end of the first movable wire clamp arm 16 and one end of the second movable wire clamp arm 17 are respectively adjustably connected to the linkage shaft 15, and the middle parts of the first movable wire clamp arm 16 and the second movable wire clamp arm 17 are respectively connected to the side wall of the fixed wire clamp hook 2 through the pin shaft 8.

[0054] In actual use, if the degree of closure of the hooking area between the movable wire clamp hook 3 and the fixed wire clamp hook 2 is to be adjusted, the linkage shaft 15 can be moved a corresponding distance along the limiting groove 18 according to the desired degree of closure of the hooking area between the movable wire clamp hook 3 and the fixed wire clamp hook 2, and then the linkage shaft 15 and the limiting grooves 18 at one end of the first movable wire clamp arm 16 and one end of the second movable wire clamp arm 17 are temporarily fixed. In this way, since the linkage shaft 15 moves a certain distance along the limiting groove 18, compared with before the linkage shaft 15 moves in the limiting groove 18, after the linkage shaft 5 moves a certain distance in the vertical direction, the movable wire clamp hook 3 can be adjusted. The degree of closure of the hanging area between the movable wire clamp hook 3 and the fixed wire clamp hook 2 is larger than before, so it can be suitable for clamping power transmission and distribution wires of different thicknesses, that is, when clamping thin power transmission and distribution wires, the degree of closure of the hanging area between the movable wire clamp hook 3 and the fixed wire clamp hook 2 can be adjusted to be more closed (more closed: the hanging area is smaller, so as to clamp the thin power transmission and distribution wires); when clamping thick power transmission and distribution wires, the degree of closure of the hanging area between the movable wire clamp hook 3 and the fixed wire clamp hook 2 can be adjusted to general (adjusted to general: suitable for clamping the hanging area of ​​thick power transmission and distribution wires, so as to clamp the thick power transmission and distribution wires).

[0055] See also Figure 1 and Figure 3 In order to realize the adjustable connection between the limit slot 18 and the linkage shaft 15, a first external thread 19 and a second external thread are respectively provided at both ends of the linkage shaft 15. The first external thread 19 and the second external thread are respectively threadedly connected with a tensioning nut 20, and the tensioning nut 20 respectively conflicts with the outer wall of the limit slot 18 at one end of the first movable line clamp arm 16 and the second movable line clamp arm 17.

[0056] In actual use, when adjusting the linkage shaft in the limit slot 18, first remove the tensioning nuts 20 at both ends of the linkage shaft 15 in the limit slot 18 to make the linkage shaft 15 in a sliding state in the limit slot 18, and then move the linkage shaft 15 to the left or right a certain distance along the limit slot 18 according to the degree of closure required for the hanging area between the movable wire clamp hook 3 and the fixed wire clamp hook 2, and then use the tensioning nut 20 to threadably connect the first external thread 19 and the second external thread at both ends of the linkage shaft 15, so that the tensioning nut 20 respectively contacts the groove wall of the limit slot 18 at one end of the first movable wire clamp arm 16 and one end of the second movable wire clamp arm 17, so as to lock the linkage shaft 15.

[0057] It should be noted that in order to prevent the movable wire clamp hook 3 from interfering with the fixed wire clamp hook 2 when they cooperate to clamp the power transmission and distribution lines, an area 21 for accommodating part of the fixed wire clamp hook 2 is defined between the other end of the first movable wire clamp arm 16 in the movable wire clamp hook 3 and the other end of the second movable wire clamp arm 17.

[0058] See also Figure 1 and Figure 5 The fixed wire clamp hook 2 used for clamping and cooperating with the movable wire clamp hook 3 includes a fixed block 22, a first fixed wire clamp arm 23, a second fixed wire clamp arm 24 and a connecting block 25; wherein the fixed block 22 is used as a mounting base for the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24; the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 are used to define a clamping area for partially clamping the power transmission and distribution line; the connecting block 25 is used to connect the other ends of the opened and closed first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 to be closed, thereby indirectly improving the overall connection strength of the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24.

[0059] Specifically, the middle parts of the first movable wire clamp arm 23 and the second movable wire clamp arm 24 are hinged to the two side walls of the fixed block 22 through the pin shaft 8 respectively, the bottom of the fixed block 22 is connected to the top of the hanging base 1, the top of the fixed block 22 is connected to one end of the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 respectively, the other ends of the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 are connected to the connecting block 25, the tops of the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 are respectively connected to the outer wall of the hanging hanger 6, and the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 are both arc-shaped structures.

[0060] In this way, since the components constituting the fixed wire clamp hook 2 include the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24, even if the first fixed wire clamp arm 23 or the second fixed wire clamp arm 24 in the fixed wire clamp hook 2 is damaged, the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 can still be used, which indirectly improves the practicality of the fixed wire clamp hook 2.

[0061] See also Figure 1 and Figure 3 The hanging piece 6 connected to the hook connected to the hanging rope on the bottom of the drone is a hanging ring, and the outer wall of the hanging ring is connected to the top of the first fixed wire clamp arm 23 and the second fixed wire clamp arm 24 respectively.

[0062] In actual use, when the UAV is connected to the auxiliary grounding hanging device of the UAV platform, one end of the hanging rope is tied to the bottom of the UAV, and the other end of the hanging rope is tied to a hook, and then the hook is hung on the lifting ring on the auxiliary grounding hanging device of the UAV platform to connect or assemble the UAV and the auxiliary grounding hanging device of the UAV platform, so as to facilitate the subsequent process of using the UAV to fly the auxiliary grounding hanging device of the UAV platform to the suspended power transmission and distribution line for grounding and hanging.

[0063] It should be noted that the shape of the hanging ring can be any one of circular, ring and rectangular, and the hanging ring can also be set to other shapes according to actual needs.

[0064] See also Figure 1 and Figure 5The grounding wire connector 5 for hanging the grounding wire on the auxiliary grounding hanging device of the UAV platform is a bolt with a nut. The two bolts with nuts are respectively threadedly connected to the outer wall of the hanging base 1, and the grounding wire is hung on or wrapped around the bolt with nuts.

[0065] In actual use, when the grounding wire is hung on the hanging base 1 in the auxiliary grounding hanging device of the UAV platform, first wrap one end of the grounding wire around the bolt with a nut and tie a knot, and then thread the bolt with a nut with the grounding wire to the threaded hole on the outer wall of the hanging base 1 to hang the grounding wire on the hanging base 1, so as to facilitate the subsequent hanging of the UAV platform auxiliary grounding hanging device connected to the grounding wire on the transmission and distribution line.

[0066] The present application integrates a hanging base, a fixed wire clamp hook, a movable wire clamp hook, a movable wire clamp hook driving component, a grounding wire connector and a hanging hanger into an auxiliary grounding hanging device for an unmanned aerial vehicle platform. When the grounding wire is hung on the power transmission and distribution line, the unmanned aerial vehicle platform auxiliary grounding hanging device can be controlled by the unmanned aerial vehicle remote control to fly the unmanned aerial vehicle platform auxiliary grounding hanging device to the power transmission and distribution line where maintenance is required, and the power transmission and distribution line is made to enter the power transmission and distribution line clamping area defined by the fixed wire clamp hook and the movable wire clamp hook from the opening between the fixed wire clamp hook and the movable wire clamp hook, and then the wireless remote control is used to control the movable wire clamp hook driving component to drive the movable wire clamp hook to move in the direction of the fixed wire clamp hook, so that the fixed wire clamp hook and the movable wire clamp hook are connected. The opening between the clamping hooks is closed, and the transmission and distribution lines are restricted to the transmission and distribution line clamping area defined by the fixed wire clamping hook and the movable wire clamping hook. In this way, the auxiliary grounding hanging device of the UAV platform connected to the grounding wire is hung on the transmission and distribution line to be inspected. There is no need to hang the grounding wire on the transmission and distribution line with the help of an electric lifting device or for maintenance personnel to climb to the top of the tower along the iron tower to hang the grounding wire on the transmission and distribution line. This solves the problem of low efficiency and safety risks in hanging grounding wires caused by relying on manual climbing to hang grounding wires when hanging and grounding transmission and distribution lines during maintenance of transmission and distribution lines.

[0067] The present application uses a drone to hang the auxiliary grounding hanging device of the drone platform on the power transmission and distribution line. Compared with the traditional manual climbing hanging method, the drone has the characteristics of rapid response and flexible maneuverability. It can reach the place where the power transmission and distribution line needs to be hung in a short time, and complete the operation of hanging the grounding wire on the power transmission and distribution line or removing the grounding wire hung on the power transmission and distribution line. This not only improves work efficiency and shortens power outage time, but also reduces the impact on users' electricity consumption.

[0068] The present application can hang the ground wire on the transmission and distribution line by cooperating with the auxiliary grounding hanging device of the drone and the drone platform. There is no need to hang the ground wire on the transmission and distribution line by using an electric lifting device or the maintenance personnel climbing to the top of the tower to hang the ground wire on the transmission and distribution line. This can not only avoid direct contact between the operating personnel and the high-voltage lines, but also reduce safety risks such as electric shock and falling from heights.
