[0043] Please refer to Figure 1-Figure 4 This embodiment provides a substation inspection drone 100, which includes a main body 110, a rotor assembly 120, a frame 130, an image acquisition frame 140, and an image pan-tilt platform 150;

[0044] The rotor assembly 120 and the frame 130 are both connected to the main body 110;

[0045] A mounting slot 111 is provided on one side of the main body 110 , and the image acquisition frame 140 is rotatably connected to the mounting slot 111 , and the image platform 150 is connected to the image acquisition frame 140 ;

[0046] The image acquisition frame 140 is used to drive the image platform 150 to rotate relative to the main body 110 so that the image platform 150 has at least a position located on the upper side of the main body 110 and a position located on the lower side of the main body 110 .

[0047] Please refer to Figure 1-Figure 4 The working principle of the substation inspection drone 100 is:

[0048] The substation inspection drone 100 includes a main body 110, a rotor assembly 120, a frame 130, an image acquisition frame 140, and an image platform 150. The rotor assembly 120 and the frame 130 are both connected to the main body 110. A mounting slot 111 is provided on one side of the main body 110, and the image acquisition frame 140 is rotatably connected to the mounting slot 111. The image platform 150 is connected to the image acquisition frame 140. The image acquisition frame 140 is used to drive the image platform 150 to rotate relative to the main body 110, so that the image platform 150 has at least one position located above the main body 110 and one position located below the main body 110. As a result, the substation inspection drone 100 can fly via the rotor assembly 120 and land via the frame 130.

[0049] During use, the substation inspection drone 100 can adjust the relative position of the image platform 150 by rotating the image acquisition frame 140 relative to the main body 110, so that the image platform 150 can be located on the upper side or lower side of the main body 110, and its relative position can be adaptively adjusted according to the needs of use. Therefore, the movement of the image acquisition frame 140 and the freedom of movement of the image platform 150 itself can expand the range of images that can be collected by the image platform 150 of the substation inspection drone 100, so that corresponding inspection work can be carried out at different heights, and upward or downward shooting can be carried out according to needs, thereby adapting to the inspection needs of the substation, reducing inspection costs, and improving inspection efficiency.

[0050] It should be noted that, in this embodiment, the function of the image platform 150 is to perform corresponding image acquisition work. It can be a camera platform in the prior art. Moreover, during use, the image platform 150 itself has multiple degrees of freedom. Moreover, when the image platform 150 is selected, since the image acquisition frame 140 has rotational freedom, the structure of the image platform 150 can be simplified on this basis. In addition, through such a setting method, when the rotational freedom of the image platform 150 cannot meet the requirements, the image acquisition frame 140 can be rotated to ensure the normal progress of the image acquisition work.

[0051] For further information, please refer to Figure 1-Figure 4 In this embodiment, to facilitate the installation of the image acquisition frame 140 and to drive the image acquisition frame 140 to rotate relative to the main body 110, the substation inspection drone 100 further includes a drive unit 160. The drive unit 160 is connected to the main body 110 and is used to drive the image acquisition frame 140 to rotate relative to the main body 110. The main body 110 is also equipped with a drive compartment 112 for accommodating the drive unit 160. The drive compartment 112 is located on one side of the mounting slot 111.

[0052] Please refer to Figures 1-6 , and when configuring the image acquisition frame 140, the present embodiment adopts the image acquisition frame 140 including a mounting cylinder 141, a rotating motor 142, a rotating rod 143, a movable block 144, a guide frame 145 and a movable platform 146;

[0053] The rotating motor 142 is housed within the mounting tube 141. The rotating rod 143 is drivingly connected to the main shaft of the rotating motor 142. The movable block 144 is threadedly connected to the rotating rod 143. The movable block 144 is connected to the guide frame 145. The guide frame 145 is slidably connected to the mounting tube 141. The movable platform 146 is connected to the guide frame 145 and is located outside the mounting tube 141. The image platform 150 is connected to the movable platform 146.

[0054] Thus, during use, the rotating motor 142 can be used to drive the rotating rod 143 to rotate, thereby driving the movable block 144 and the guide frame 145 to move along the axis of the rotating rod 143, thereby driving the movable platform 146 to move. The movement of the movable platform 146 can drive the image platform 150 connected to the movable platform 146 to move. With this arrangement, the position of the image platform 150 relative to the main body 110 can be adjusted by the movement of the movable platform 146. In particular, when the image platform 150 is located above or below the main body 110, its height relative to the main body 110 can be changed, thereby enabling the substation inspection drone 100 to meet different usage requirements.

[0055] Based on the above structure, in this embodiment, the image acquisition frame 140 rotates relative to the mounting slot 111 in a direction perpendicular to the axis of the rotating rod 143. Furthermore, a rotating connector 147 is provided on the outside of the mounting tube 141 for rotational connection with the mounting slot 111. Furthermore, to guide the movement of the movable platform 146, a guide portion is disposed within the mounting tube 141, which slidably engages with a guide frame 145 and extends along the axis of the rotating rod 143.

[0056] For further information, please refer to Figures 1-8 In this embodiment, the image acquisition frame 140 is rotatably connected to the mounting groove 111. Therefore, in order to prevent some debris from falling into the mounting groove 111 and causing a malfunction in the rotation of the image acquisition frame 140, the substation inspection drone 100 further includes two sets of shielding units 170. The two sets of shielding units 170 are respectively located on the upper and lower sides of the main body 110. Each set of shielding units 170 includes a movable baffle 171 and an elastic member 172.

[0057] The movable baffle 171 is movably connected to the main body 110 , and the elastic member 172 is connected to the main body 110 , so that the movable baffle 171 has a tendency to move toward the mounting groove 111 ;

[0058] The movable baffle 171 has a first position where it blocks at least a portion of the upper side or the lower side of the installation slot 111 , and a second position where the movable baffle 171 is located outside the installation slot 111 .

[0059] With the above-mentioned structural arrangement, the two blocking units 170 can block the upper and lower sides of the mounting groove 111, thereby preventing debris from falling into the mounting groove 111 and leading the rotation of the image acquisition frame 140; and in the present embodiment, when the image acquisition frame 140 rotates, due to the arc-shaped end portion thereof, it can make contact with the movable baffle 171 smoother, thereby avoiding the situation of abutment and jamming. That is, when the movable baffle 171 completely blocks the upper side or the lower side of the mounting groove 111, the image acquisition frame 140 will smoothly contact the movable baffle 171 after rotating toward that side, and after it abuts against the movable baffle 171, it can drive the movable baffle 171 to overcome the elastic force of the elastic member 172 and move in the direction of opening the mounting groove 111, while the movable baffle 171 on the other side is in a state of blocking the mounting groove 111.

[0060] On this basis, the main body 110 is provided with two sets of sliding grooves, which correspond to the two sets of blocking units 170 for sliding cooperation respectively; wherein, at least part of the two sets of sliding grooves extend into the mounting groove 111, so that the movable baffle 171 can slide into the mounting groove 111 to block it; and in order to prevent the movable baffle 171 from sliding out under the action of the elastic member 172, a limiting platform 173 is provided at one end of the sliding groove extending to the mounting groove 111, and the limiting platform 173 is used to abut against the movable baffle 171 to limit the movement of the movable baffle 171 toward the mounting groove 111.

[0061] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
