[0029] Example 1

[0030] The preferred embodiment of the hyperspectral geological survey device provided by the utility model is as follows: Figures 1 to 6 As shown: a hyperspectral geological survey device, including an unmanned aerial vehicle body 5, propellers 6 are arranged around the top of the unmanned aerial vehicle body 5, a ground feature spectrometer 10 is fixedly connected to the middle position of the bottom of the unmanned aerial vehicle body 5, a protective component 7 is arranged on one side of the bottom of the unmanned aerial vehicle body 5, and a support leg 1 is fixedly connected to the bottom of the unmanned aerial vehicle body 5. A fixing groove 12 is opened at the lower end of the inner part of the support leg 1, and a damper 13 is fixedly connected to the inner top wall of the fixing groove 12. A slider 11 is fixedly connected to the bottom end of the damper 13, and a shock-absorbing spring 14 is wound around the surface of the damper 13 at the top of the slider 11. The top of the shock-absorbing spring 14 is fixedly connected to the inner top wall of the fixing groove 12, and the bottom end of the slider 11 is fixedly connected to a shock-absorbing rod 9 extending to the outside of the support leg 1, and the bottom end of the shock-absorbing rod 9 is fixedly connected to a mounting seat 3, one end of the mounting seat 3 is provided with a mounting component 2, and the bottom end of the mounting seat 3 is movably connected to a buffer seat 4.

[0031] The protection component 7 includes a fixing frame 704, which is fixedly connected to one side of the bottom end of the UAV body 5. A reserved groove 706 is opened at the lower end of one side of the fixing frame 704. A micro servo motor 705 is fixedly connected to one end of the fixing frame 704. The output end of the micro servo motor 705 extends to the inside of the reserved groove 706 and is fixedly connected to a threaded rod 702 through a coupling. A threaded block 707 is threadedly connected to the surface of the threaded rod 702. One side of the threaded block 707 extends to the outside of the reserved groove 706 and is fixedly connected to a protection plate 701. By starting the micro servo motor 705 to drive the threaded rod 702 to rotate, the threaded block 707 slides and drives the protection plate 701 to slide until the ground object spectrometer 10 is fully opened, which is convenient for the geological survey operation of the ground object spectrometer 10. When the UAV body 5 is about to land on the ground, the protection plate 701 can slide to completely block and protect the bottom end of the ground object spectrometer 10 to avoid damage to the ground object spectrometer 10 caused by obstacles such as rock protrusions during landing.

[0032] In this embodiment, the cross-sectional area of ​​the protective plate 701 is larger than the cross-sectional area of ​​the ground object spectrometer 10, and the cross-sectional diameter of the protective plate 701 is smaller than the spacing between the legs 1. By using a protective plate 701 of appropriate size, it is convenient to fully shield and protect the ground object spectrometer 10, and the protective plate 701 can be slid open between the legs 1.

[0033] In this embodiment, the cross-section of the reserved groove 706 and the threaded block 707 is inverted convex, and one side of the threaded block 707 is fixedly connected to the surface of the protective plate 701 by bolts.

The sliding of the connecting block 708 on the surface of the slide bar 703 improves the smoothness of the sliding of the protective plate 701.

[0035] Example 2

[0036] On the basis of Example 1, a preferred embodiment of the hyperspectral geological survey device provided by the utility model is as follows: Figures 1 to 6As shown: the mounting assembly 2 includes a card slot 205, the card slot 205 is opened at the bottom end of the mounting seat 3, a sliding slot 206 is opened on one side of the mounting seat 3 above the card slot 205, the inner top wall of the sliding slot 206 is fixedly connected with a fixing spring 201, the bottom end of the fixing spring 201 is fixedly connected with a sliding block 207, one side of the sliding block 207 is fixedly connected with a limiting plate 204 extending to the outside of the sliding slot 206, and the top of the buffer seat 4 is fixedly connected with a card block 202, by utilizing the card block 202 and the inside of the card slot 205, and the elastic force of the fixing spring 201, the limiting plate 204 is lowered to limit and clamp one side of the card block 202, thereby realizing rapid disassembly and assembly between the mounting seat 3 and the buffer seat 4, and facilitating the replacement of the buffer seat 4 that is severely worn or damaged.

[0037] In this embodiment, a locking structure is formed between the block 202 and the inside of the slot 205. The cross-sections of the block 202 and the slot 205 are inverted convex. The locking between the inverted convex block 202 and the inside of the slot 205 is used to improve the stability of the initial locking installation of the mounting seat 3 and the buffer seat 4.

[0038] In this embodiment, friction ridges 203 are fixedly connected to one side of the limit plate 204 at equal intervals. The cross-section of the friction ridges 203 is rectangular. The rectangular friction ridges 203 are used to increase the contact friction between the user's fingers and the limit plate 204, thereby facilitating the sliding of the limit plate 204.

[0039] In this embodiment, one side of the limit plate 204 is in close contact with one side of the slot 205, and the other side of the limit plate 204 and one side of the sliding block 207 are welded into an integrated structure. The close contact with one side of the slot 205 ensures that the block 202 is tightly and firmly engaged with the inside of the slot 205.

[0040] Furthermore, the bottom of the buffer seat 4 is provided with anti-skid grooves 8 at equal angles. The shape of the anti-skid grooves 8 in a top view is arc-shaped. The arc-shaped anti-skid grooves 8 are used to improve the anti-skid stability between the bottom of the buffer seat 4 and the ground.

[0041] In addition, a sliding structure is formed between the slider 11 and the interior of the fixed groove 12. The shape of the slider 11 and the fixed groove 12 in the top view is a cross. The sliding of the cross-shaped slider 11 and the interior of the fixed groove 12 is utilized to improve the stability of the up and down sliding of the shock-absorbing rod 9, thereby facilitating the smooth buffering and shock absorption of the drone body 5.

[0042] The working principle and use process of the utility model are as follows: first, the propeller 6 is rotated to make the drone body 5 rise, and when the ground object spectrometer 10 needs to be used, the micro servo motor 705 is started to drive the threaded rod 702 to rotate, and the threaded rod 702 and the threaded block 707 are matched with each other, so that the threaded block 707 slides and drives the protective plate 701 to slide until the ground object spectrometer 10 is fully opened, which is convenient for the geological survey operation of the ground object spectrometer 10. When the drone body 5 is about to land on the ground, the micro servo motor 705 can be started again to make the protective plate 701 slide to completely cover the bottom of the ground object spectrometer 10 for protection, so as to avoid damage to the ground object spectrometer 10 caused by obstacles such as rock protrusions during landing, thereby extending its service life;

[0043] At the same time, when the drone body 5 descends, the buffer seat 4 first contacts the ground. At this time, the arc-shaped anti-skid pattern 8 is used to improve the anti-skid stability between the bottom end of the buffer seat 4 and the ground. At the same time, the buffer seat 4 will rise and drive the mounting seat 3 to rise, thereby causing the shock absorbing rod 9 and the slider 11 to slide and compress the damper 13 and the shock absorbing spring 14. At this time, the shock absorbing spring 14 is used to absorb the impact energy generated by the external descent, and the damper 13 is used to consume the elastic potential energy absorbed by the shock absorbing spring 14. Then, the damper 13 and the shock absorbing spring 14 can be used to achieve buffering and shock absorption when the drone body 5 descends, thereby avoiding damage to the ground object spectrometer 10 caused by the descending impact.

[0044] When the bottom end of the buffer seat 4 is severely worn or damaged, resulting in unstable support for the drone body 5, the limit plate 204 can be moved to drive the sliding block 207 to slide inside the sliding groove 206 to compress the fixed spring 201 until the slot 205 is fully opened, and then the buffer seat 4 is pushed hard to make the block 202 completely disengage from the inside of the slot 205, thereby realizing the disassembly of the buffer seat 4. During installation, the limit plate 204 is first moved to open the slot 205, and then the block 202 is slid into the slot 205, and then the limit plate 204 is released. The elastic force of the fixed spring 201 is used to make the sliding block 207 slide and drive the limit plate 204 to return to its original position to limit and tighten one side of the block 202, thereby preventing the limit plate 204 from disengaging from the inside of the slot 205, thereby realizing a firm installation between the buffer seat 4 and the mounting seat 3.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
