[0002] The UAV remote sensing mapping data acquisition device is an auxiliary device used to measure and collect the shape, size, spatial position and attributes of natural geographical elements or surface artificial facilities. It is widely used in the field of surveying and mapping. The existing UAV remote sensing mapping data acquisition device includes a UAV, a bracket and a hyperspectral camera. The bracket is set at the bottom of the UAV, and the hyperspectral camera is installed at the bottom of the bracket. When performing data collection operations, the UAV is equipped with a hyperspectral camera to fly to a designated shooting position and shoot the designated area to collect relevant data. However, in the existing technology, the hyperspectral camera and the bracket are mostly fixed with bolts. Although this installation method is relatively firm, the bolt fixing has the problem of being very inconvenient to disassemble and assemble. When the hyperspectral camera needs to be maintained, it is relatively inconvenient to disassemble and assemble. In view of this, in-depth research on the above problems has led to the emergence of this case. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: In conjunction with the instructions attached Figure 1-3 The U-shaped mounting groove 2 is provided on the lower end bracket 1 of the mapping drone body, and a clamping clamping assembly is provided in the U-shaped mounting groove 2. The movable end of the clamping clamping assembly is provided with a locking block 3 that matches the side slot of the hyperspectral camera; the above-mentioned clamping clamping assembly includes a drawing screw 4, a guide, a movable seat 5, a connecting shaft 6, a handwheel 7 and a limit locking member. The drawing screw is rotatably arranged in the U-shaped mounting groove 2, and the guide members are symmetrically arranged on both sides of the drawing screw 4. The movable seat 5 is arranged on the movable end of the guide member and is connected to the locking block 3. The movable seat 5 and the drawing screw 4 are threadedly connected by a screw nut, and the connecting shaft 6 is arranged on the exposed end of the drawing screw 4. The handwheel 7 is installed at one end of the connecting shaft 6. The limit locking member is fixed on the side wall of the U-shaped mounting groove 2 and the center axis hole is interference fit with the connecting shaft 6, wherein the guide member includes The cam 8 is a kind of fixed frame 2, and the cam 8 is a kind of fixed frame 2, and the cam 8 is a kind of fixed frame 2, and the cam 8 is a kind of fixed frame 2.

[0018] In the specific implementation process, as a preferred setting, the above-mentioned limit locking member includes a shell 10, a ratchet 11, a control member and a pawl 12. The shell 10 is buckled on the outside of the connecting shaft 6 and fixedly connected to the side wall of the U-shaped mounting groove 2. The ratchet 11 is fixedly sleeved on the connecting shaft 6 and is located in the shell 10. A rectangular notch is provided on the side wall of the shell 10. The control member is installed at the position of the rectangular notch. One end of the pawl 12 is rotatably connected to the inner wall of the shell 10, and the other end is inserted into the tooth groove of the ratchet 11. One side of the pawl 12 is connected to the inner wall of the shell 10 through a spring 13, and the other side is hinged to one end of the control member. The control member includes a V-shaped rod 14 and a pull rod 15. The bent part of the V-shaped rod 14 is rotatably matched with the support at the rectangular notch position of the shell 10. One end of the pull rod 15 is hinged to the V-shaped rod 14, and the other end is hinged to the side of the pawl 12. The exposed end of the above-mentioned V-shaped rod 14 is provided with a pressing ball 16, see the appendix of the instruction manual. Figure 3 It can be seen that when the hand wheel 7 drives the connecting shaft 6 to rotate counterclockwise, the pawl 12 will not limit the ratchet 11, so this direction is selected as the movement control direction of the locking blocks 3 approaching each other, that is, when the control hand wheel 7 is rotated counterclockwise, the drawing rod drives the moving seats 5 on both sides to approach each other, so that the locking block 3 is used to clamp and position the side slots of the hyperspectral camera. After the positioning is completed, the pawl 12 is clamped into the tooth groove of the ratchet 11 under the tension of the spring 13, and the mapping drone body is flying and on the ground. During the lifting or lowering process, even if the drawing screw 4 is subjected to external force vibration, it will not rotate clockwise, which can effectively ensure the stability of the clamping; similarly, when the hyperspectral camera needs to be disassembled, push the button ball 16 to rotate the V-shaped rod 14, and then pull the pawl 12 out of the tooth groove of the ratchet 11 through the pull rod 15, releasing the limiting effect on the ratchet 11, and turning the handwheel 7 clockwise to make the movable seats 5 on both sides move away from each other, the locking block 3 is separated from the clamping slot position, and the hyperspectral camera can be removed.

[0019] In the specific implementation process, as a preferred setting, the side wall of the locking block 3 is affixed with a rubber anti-slip strip 17 to improve the clamping stability while avoiding scratches on the body of the hyperspectral camera.

[0020] Among them, it should be pointed out that the selection and structure of the above-mentioned hyperspectral camera can refer to the Specim AFX17 hyperspectral camera sold by Wengkaier (Guangdong) Technology Co., Ltd.; the specific shape design of the locking block 3 can be adaptively matched according to the actual selected hyperspectral camera slot structure.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
