Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0029] like Figures 1 to 3As shown, in this embodiment, the grounding device of the drone is connected to the drone body 1. The grounding device of the drone includes: a conductive member, a retractable structure, and a telescopic structure. The first end of the conductive member is used for grounding, and the second end of the conductive member is used for electrical connection to the maintenance line. The retractable structure is rotatably connected to the drone body 1, and the conductive member is wound on the retractable structure so that the first end of the conductive member has a retracted state for moving close to the drone body 1 and a released state for moving away from the drone body 1. The telescopic structure is telescopically connected below the drone body 1, and the second end of the conductive member is connected to the telescopic structure, and the telescopic structure is telescopic to drive the second end of the conductive member to move close to the maintenance line or away from the maintenance line.

[0030] In this way, the drone body 1 is raised to the vicinity of the maintenance line on the tower so that the conductive part can be moved to the vicinity of the maintenance line. The conductive part is driven by the drone body 1 to the vicinity of the maintenance line, and the second end of the conductive part is brought close to the maintenance line and abutted against the maintenance line through the extension and retraction of the telescopic structure to achieve electrical connection, and then the first end of the conductive part is switched to a released state through the rotation of the retracting structure, so that the first end of the conductive part can be moved downward to the ground, so that the first end of the conductive part can be grounded. In this way, it is avoided that the electrician needs to go up the tower to connect the ground wire and the maintenance line, making the operation of grounding the maintenance line simpler and reducing the potential safety hazards caused by the electrician going up the tower. Therefore, the technical solution of this embodiment effectively solves the problem that the operation method of grounding the maintenance line in the related art is complicated and has great potential safety hazards.

[0031] like Figure 2 and Figure 3 As shown, the grounding device of the drone also includes a mounting shell 2 connected to the drone body 1 and a mounting plate 14 arranged on the mounting shell 2, and the retracting structure is detachably connected to the mounting plate 14. The installation of the mounting shell 2 facilitates the connection between the drone body 1 and the grounding device of the drone. The installation of the mounting plate 14 facilitates the installation of the retracting structure.

[0032] like Figure 2 and Figure 3 As shown, the retracting structure includes a rotating sleeve 19 rotatably disposed on the mounting plate 14 and a driving motor 16 disposed on the mounting plate 14. The driving motor 16 drives the rotating sleeve 19 to rotate so that the first end of the conductive member switches between a retracted state and a released state. The drive motor 16 is configured to drive the rotating sleeve 19 to rotate so that the conductive member can be wound around the rotating sleeve 19 or released from the rotating sleeve 19. The configuration of the drive motor 16 enables the first end of the conductive member to switch between a retracted state and a released state more conveniently and quickly.

[0033] like Figure 2 and Figure 3As shown, the winding structure also includes two baffles 13 arranged at intervals on the rotating sleeve 19, and the conductive member is wound on the rotating sleeve 19 between the two baffles 13. The arrangement of the two baffles 13 can limit the conductive member so that the conductive member can be wound on a predetermined position of the rotating sleeve 19 for easy use. The winding structure also includes a driving gear 15 arranged on the output shaft of the driving motor 16 and a driven gear 21 arranged on the rotating sleeve 19, and the driving gear 15 is meshed with the driven gear 21. The arrangement of the driving gear 15 and the driven gear 21 makes the transmission cooperation between the driving motor 16 and the rotating sleeve 19 more reliable and easy to process and install.

[0034] In other embodiments, the winding structure further includes two baffles 13 spaced apart on the rotating sleeve 19, and the conductive member is wound on the rotating sleeve 19 between the two baffles 13. Alternatively, the winding structure further includes a driving gear 15 disposed on the output shaft of the driving motor 16 and a driven gear 21 disposed on the rotating sleeve 19, and the driving gear 15 is meshed with the driven gear 21.

[0035] like Figure 2 and Figure 3 As shown, the conductive member includes a grounding wire 12 wound on a rotating sleeve 19 and a grounding terminal 20 arranged at the first end of the grounding wire 12, and the grounding terminal 20 has a retracted state and a released state. The provision of the grounding terminal 20 makes the grounding operation of the conductive member more reliable. The grounding device of the drone also includes a conductive column 22 arranged in the rotating sleeve 19, and the rotating sleeve 19 can rotate relative to the conductive column 22. The conductive column 22 can be electrically connected to the maintenance line, and a avoidance hole is provided on the rotating sleeve 19. The second end of the grounding wire 12 passes through the avoidance hole and is electrically connected to the conductive column 22. In this way, when the conductive column 22 can be electrically connected to the maintenance line, the conductive column 22 can be in an approximately stationary state, and the rotating sleeve 19 can rotate relative to the conductive column 22, so that the grounding wire 12 can be wound on the rotating sleeve 19.

[0036] like Figure 2 and Figure 3 As shown, a plurality of spring conductive members are fixedly provided on the second end of the grounding wire 12, and the plurality of spring conductive members are electrically connected to the grounding wire 12. When the rotating sleeve 19 rotates and drives the second end of the grounding wire 12 to rotate around the axis of the rotating sleeve 19, the spring conductive members are electrically connected and abutted with the conductive column 22. The spring conductive members make the electrical connection between the grounding wire 12 and the conductive column 22 more reliable. When the conductive column 22 is fixedly connected and electrically connected to the maintenance line, the second end of the grounding wire 12 rotates around the axis of the conductive column 22, and the grounding wire 12 is electrically connected to the conductive column 22 through the spring conductive members. In this way, the situation in which the conductive column 22 rotates with the rotating sleeve 19 and the conductive members are entangled together is avoided. In this embodiment, the entanglement problem of the elastic spiral cable 18 described below is avoided.

[0037] like Figure 2 and Figure 3 As shown, the telescopic structure includes a connecting plate 5 spaced apart from the mounting housing 2, a telescopic rod 3 connected between the mounting housing 2 and the connecting plate 5, and an electric push rod 4 connected between the mounting housing 2 and the connecting plate 5. The conductive member also includes a power connection post 8 electrically connected to the conductive column 22 and a power connection head 7 electrically connected to the power connection post 8. The power connection post 8 is fixedly arranged on the connecting plate 5, the power connection head 7 is connected below the power connection post 8, and the electric push rod 4 is telescopic to drive the power connection head 7 to approach or move away from the maintenance line. The setting of the connecting plate 5 facilitates the installation of the power connection post 8. The setting of the electric push rod 4 facilitates the pushing of the connecting plate 5 to approach or move away from the mounting housing 2, and the setting of the telescopic rod 3 can be telescoped following the movement of the connecting plate 5, reducing the rotation of the connecting plate 5 relative to the mounting housing 2, and making the movement of the connecting plate 5 more stable. The setting of the power connection head 7 makes the electrical connection between the power connection post 8 and the maintenance line more reliable.

[0038] like Figure 2 and Figure 3 As shown, the conductive member also includes an elastic spiral cable 18 electrically connected between the conductive column 22 and the connecting column 8. The setting of the elastic spiral cable 18 can adjust the shape of the elastic spiral cable 18 according to the change in the distance between the connecting plate 5 and the mounting shell 2, reducing the possibility of the elastic spiral cable 18 being entangled on other structures of the drone due to drooping, and ensuring the normal use of the drone. The grounding device of the drone also includes a mounting frame 17 spaced apart from the mounting plate 14, and the rotating sleeve 19 is rotatably arranged on the mounting frame 17. The setting of the mounting frame 17 makes the rotation of the rotating sleeve 19 more stable, which is convenient for the installation of the rotating sleeve 19.

[0039] In other embodiments, the conductive member further comprises an elastic spiral cable 18 electrically connected between the conductive column 22 and the connecting column 8. Alternatively, the grounding device of the drone further comprises a mounting frame 17 spaced apart from the mounting plate 14, and the rotating sleeve 19 is rotatably disposed on the mounting frame 17.

[0040] In other embodiments, the conductive column 22 is sleeved in the rotating sleeve 19 and rotates synchronously with the rotating sleeve 19, and the conductive column 22 is electrically connected to the grounding wire 12. A conductive rod is fixedly arranged on the mounting frame 17, and the conductive column 22 can rotate relative to the conductive rod, and the conductive column 22 is in contact with and electrically connected to the conductive rod. The conductive rod is fixedly connected to the elastic spiral cable 18 and is electrically connected.

[0041] like Figure 2 and Figure 3As shown, the grounding device of the drone also includes a camera device 6 arranged below the connecting plate 5, and the camera device 6 is used to monitor the environment near the power connection head 7. Since there are usually more debris around the maintenance line, resulting in a smaller space around the maintenance line, the camera device 6 can be used to better observe the situation near the maintenance line to adjust the posture of the drone body 1 so that the power connection post 8 can be more conveniently and reliably connected to the maintenance line. The grounding device of the drone also includes a horizontal plate 11 arranged on the mounting plate 14 and a laser device 10 arranged on the horizontal plate 11, and the laser device 10 is arranged adjacent to the grounding terminal 20. The setting of the laser device 10 can indicate the position of the grounding terminal 20 to the electrician on the ground, so that the electrician can quickly find the grounding terminal 20, so as to facilitate the grounding operation of the grounding terminal 20. In this embodiment, the light outlet of the laser device 10 is arranged downward.

[0042] In other embodiments, the grounding device of the drone further includes a camera device 6 disposed below the connection plate 5, and the camera device 6 is used to monitor the environment near the power connector 7. Alternatively, the grounding device of the drone further includes a horizontal plate 11 disposed on the mounting plate 14 and a laser device 10 disposed on the horizontal plate 11, and the laser device 10 is disposed adjacent to the grounding terminal 20.

[0043] The present application also provides a drone, such as Figure 1 As shown, the drone includes a drone body 1 and a grounding device connected to the drone body 1, and the grounding device is the above-mentioned drone grounding device. Since the above-mentioned drone grounding device can solve the problem of complicated operation and great safety hazards in the related art of grounding the maintenance line, the drone with the grounding device can solve the same technical problem.

[0044] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
