[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] Please see Figures 1-8 As shown, a small UAV-borne multispectral image acquisition device that is easy to install includes a UAV body 1; an image acquisition device 2 is provided below the UAV body 1, and an assembly and disassembly mechanism is provided between the UAV body 1 and the image acquisition device 2.

[0028] The assembly and disassembly mechanism includes an assembly block 10, which is located at the bottom of the drone body 1 and is fixedly connected to the top of the drone body 1. A sleeve block 11 is fitted on the outer side of the bottom of the assembly block 10 and is slidably connected to the sleeve block 11. The assembly block 10 has a square design. One end of a first return spring 13 is fixedly connected to the front and rear ends of the assembly block 10. The other end of the first return spring 13 is fixedly connected to one end of a pressing and moving rod 12. One end of the pressing and moving rod 12 is inserted into the assembly block 10 and is slidably connected to the assembly block 10. The pressing and moving rod 12 has a round rod design. The other end of the pressing and moving rod 12 is fixedly connected to a pressing and moving plate 14. The bottom of the sleeve block 11 is fixedly connected to the top of the image acquisition device 2.

[0029] During operation, the pressing and moving plates 14 at both ends of the lower part of the assembly block 10 are pressed against the assembly block 10. When the pressing and moving plates 14 press and move, they will simultaneously drive the pressing and moving rod 12 to move and retract along the inside of the assembly block 10, and squeeze the first reset spring 13 inside the assembly block 10 to retract. Then, the top of the sleeve 11 is aligned with the assembly block 10 and inserted until the sleeve 11 is inserted to the outside of the assembly block 10.

[0030] Furthermore, the front and rear ends of the outer side of the pressing moving rod 12 are also provided with moving positioning rods 15, and the outer side of the pressing moving rod 12 is fixedly connected to one end of the moving positioning rod 15. The other end of the moving positioning rod 15 passes through the assembly block 10 and is inserted into the sleeve block 11. The moving positioning rod 15 is also slidably connected to the assembly block 10 and the sleeve block 11. The moving positioning rod 15 is a circular rod design.

[0031] When in operation, pressing the moving rod 12 will cause the moving positioning rods 15 at both ends of the outer side of the moving rod 12 to move along the inside of the assembly block 10.

[0032] Furthermore, the front and rear ends of the bottom of the assembly block 10 are also provided with fixed positioning rods 16, and the bottom end of the assembly block 10 is fixedly connected to the top end of the fixed positioning rod 16. The sleeve block 11 is sleeved on the outside of the fixed positioning rod 16, and the sleeve block 11 is slidably connected to the fixed positioning rod 16. The fixed positioning rod 16 is a circular rod design.

[0033] During operation, the sleeve 11 is inserted to the outside of the assembly block 10, and the sleeve 11 is also inserted to the outside of the fixed positioning rod 16. The fixed positioning rod 16 can effectively prevent the sleeve 11 from moving back and forth.

[0034] Furthermore, fixed sleeve rods 17 are also provided on the left and right sides of the bottom of the drone body 1, and the bottom of the drone body 1 is fixedly connected to the top of the fixed sleeve rod 17. One end of the movable sleeve rod 18 is inserted inside the fixed sleeve rod 17, and the fixed sleeve rod 17 is slidably connected to the movable sleeve rod 18. The other end of the movable sleeve rod 18 abuts against the top of the sleeve block 11.

[0035] During operation, the sleeve block 11 is inserted into the assembly block 10, which will simultaneously press the bottom end of the movable sleeve rod 18, causing the movable sleeve rod 18 to move upward, and the movable sleeve rod 18 moves along the inside of the fixed sleeve rod 17.

[0036] Furthermore, a second return spring 19 is provided inside the fixed sleeve rod 17. The top end of the second return spring 19 is fixedly connected to the top end inside the fixed sleeve rod 17, and the bottom end of the second return spring 19 is fixedly connected to the top end of the movable sleeve rod 18. The movable sleeve rod 18 is designed as a round rod.

[0037] During operation, the movable sleeve 18 moves, which will compress the second return spring 19 inside the fixed sleeve 17, causing it to contract.

[0038] Furthermore, the front and rear ends of the outer side of the movable sleeve 18 near the upper position are also provided with limit sliders 20, and the outer side of the movable sleeve 18 is fixedly connected to one end of the limit slider 20. The front and rear ends of the fixed sleeve 17 are also provided with limit grooves 21, and the other end of the limit slider 20 is inserted into the limit groove 21, and the limit slider 20 is slidably connected to the limit groove 21.

[0039] During operation, the movable sleeve 18 moves, which will cause the limit slider 20 to move along the inside of the limit groove 21 until the installation is completed.

[0040] Working principle: When installation is required, simply press the pressing and moving plates 14 at both ends of the lower part of the assembly block 10 simultaneously onto the assembly block 10. As the pressing and moving plates 14 move, they will simultaneously drive the pressing and moving rod 12 to move and retract along the inside of the assembly block 10, compressing the first return spring 13 inside the assembly block 10. At the same time, as the pressing and moving rod 12 moves, it will also drive the moving positioning rods 15 at both ends of the outer side of the pressing and moving rod 12 to move along the inside of the assembly block 10, and then the sleeve block will be installed. The top of the sleeve 11 is aligned with the assembly block 10 and inserted until the sleeve 11 is inserted to the outside of the assembly block 10. Then, the pressing and moving plate 14 is released. Under the rebound force of the first return spring 13, the pressing and moving rod 12 and the moving positioning rod 15 move outward simultaneously. During the movement, the moving positioning rod 15 will insert into the sleeve 11 to fix the position of the sleeve 11. After the sleeve 11 is inserted to the outside of the assembly block 10, the sleeve 11 is also inserted to the outside of the fixed positioning rod 16. The fixed positioning rod 16 can effectively prevent the sleeve 11 from falling out. When the sleeve 11 moves back and forth and is simultaneously inserted into the assembly block 10, it will simultaneously press the bottom end of the moving sleeve 18, causing the moving sleeve 18 to move upward. The moving sleeve 18 also moves along the inside of the fixed sleeve 17. Simultaneously, when the moving sleeve 18 moves, it will press the second return spring 19 inside the fixed sleeve 17 to retract. Similarly, when the moving sleeve 18 moves, it will cause the limiting slider 20 to move along the inside of the limiting groove 21 until installation is complete. When disassembly is required, simply... Press the pressing and moving plates 14 at both ends of the assembly block 10, thereby driving the pressing and moving rod 12 and the moving positioning rod 15 to move simultaneously. During the movement, the moving positioning rod 15 will gradually disengage from the sleeve block 11 until it is completely disengaged. Then, the second reset spring 19 will automatically rebound, pushing the moving sleeve rod 18 to move downward. The moving sleeve rod 18 pushes the sleeve block 11 to move downward, causing the sleeve block 11 to move downward along the outside of the assembly block 10, while simultaneously moving the image acquisition device 2 until it is completely disengaged.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
