Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-5The utility model provides a technical solution: a multi-angle hyperspectral camera for an unmanned aerial vehicle that is easy to adjust, comprising an installation top plate 1, a threaded tube 2 is fixedly installed at the bottom end of the installation top plate 1, a transmission groove 3 is opened in the top array of the threaded tube 2, a universal ball 4 is fixedly connected to the bottom end of the threaded tube 2, a ball shell 5 is provided at the bottom end of the universal ball 4, a bracket 6 is fixedly connected to the bottom end of the ball shell 5, a hyperspectral camera 7 is fixedly installed at the bottom end of the bracket 6, a threaded sleeve 8 is threadedly connected to the top end of the threaded tube 2, a limiting groove 9 is opened at the bottom end of the threaded sleeve 8, a limiting slider 10 is slidably connected in the limiting groove 9, a transmission ring 11 is fixedly connected to the bottom end of the limiting slider 10, a transmission frame 12 is fixedly connected to the middle position of the transmission ring 11, a transmission rod 13 is fixedly connected to the bottom end of the transmission frame 12, and an extrusion block 14 is fixedly connected to the bottom end of the transmission rod 13.

[0019] An anti-skid layer 15 is fixedly connected to the bottom end of the extrusion block 14, and a plurality of protrusions are fixedly connected to the bottom end of the anti-skid layer 15. The curvature of the anti-skid layer 15 is the same as the curvature of the inner wall of the spherical shell 5. The protrusions are made of rubber, which is convenient for squeezing and fixing the spherical shell 6, so that the spherical shell 6 drives the hyperspectral camera 8 to complete angle adjustment through the bracket 7. The transmission frame 12 is designed as a cross-shaped structure, and the transmission frame 12 is slidably connected to the transmission groove 3, which is convenient for transmitting the transmission rod 14 through the transmission frame 13. The spherical shell 6 is slidably connected to the universal ball 5. The angle between the top of the spherical shell 6 and the threaded tube 2 is 60 degrees, which is convenient for controlling the angle adjustment range of the hyperspectral camera 8.

[0020] Specifically, when the utility model is used, after the mounting top plate 1 is installed on the bottom of the drone by bolts, the angle of the hyperspectral camera 7 is adjusted by rotating the spherical shell 5 and the bracket 6. Since the angle between the top of the spherical shell 5 and the threaded tube 2 is 60 degrees, the hyperspectral camera 7 can be adjusted arbitrarily within a range of 120 degrees. After adjusting to a suitable angle, the threaded sleeve 8 is rotated, and the threaded sleeve 8 rotates downward along the threaded tube 2. The rotating threaded sleeve 8 squeezes the limit slider 10 through the limit groove 9, and the squeezed limit slider 10 moves downward. The moving limit slider 10 drives the transmission ring 11 to move downward, and the transmission ring 11 drives the transmission frame 12 to move downward. The transmission frame 12 drives the transmission rod 13 to move downward, and the transmission rod 13 that moves downward squeezes and fixes the ball sleeve through the extrusion block 14 and the anti-slip layer 15, which is convenient to adjust and use.
