[0023] The present invention will now be further described with reference to the accompanying drawings.

[0024] Please see Figure 1 — Figure 5 The system includes a drone body 1, which is constructed from lightweight and high-strength carbon fiber material, ensuring structural strength while reducing overall weight and extending flight time. The drone body 1 houses a high-performance battery pack to power the drone. Multiple high-efficiency electric propellers are mounted at its four ends. A survey camera 101 is rotatably connected to the front of the drone body 1. The survey camera 101 includes a high-definition camera, an infrared thermal imager, and a lidar. The high-definition camera captures clear images of the forest surface to identify details such as tree species and growth status. The infrared thermal imager can detect hidden fire sources in the forest, which is crucial for forest fire prevention and early detection. It can also identify the activity areas and species distribution of animals based on their body temperature characteristics. The lidar is used to construct a three-dimensional terrain model of the forest. A solar panel 102 is mounted on the upper part of the drone body 1 to supplement the drone's power, thereby extending the device's flight time.

[0025] The lower end of the drone body 1 is connected to a base plate 2. The base plate 2 has mounting holes corresponding to the lower end of the drone body 1. The base plate 2 can facilitate the replacement of different drone bodies 1, and at the same time can prevent foreign objects from bumping and damaging the drone body 1 from the lower end. The lower end of the base plate 2 is connected to a storage box 3. The side end of the storage box 3 has a box hole 301. The two sides of the storage box 3 are connected to mounting plates 302. The mounting plates 302 are connected to the lower end of the base plate 2. The mounting plates 302 have mounting holes corresponding to them. The storage box 3 can be connected to the lower end of the base plate 2 through the mounting plates 302.

[0026] A first servo motor 4 is connected inside the base plate 2. A connector 5 is provided at the lower end of the first servo motor 4. The connector 5 is located at the lower end of the base plate 2. The first servo motor 4 is used to drive the connector 5 to rotate. A second servo motor 6 is connected to the side end of the connector 5. A rotating part 7 is rotatably connected inside the connector 5. The driving end of the second servo motor 6 is rotatably connected inside the connector 5, and its side end is connected to the rotating part 7. In this way, the second servo motor 6 can drive the rotating part 7 to rotate inside the connector 5. An electric telescopic push rod 8 is connected to the side end of the rotating part 7. A third servo motor 9 is connected to the driving end of the electric telescopic push rod 8. The electric telescopic push rod 8 can push the third servo motor 9 to move. A gripper 10 is connected to the driving end of the third servo motor 9. A drive rod is provided inside the gripper 10. The drive rod is used to drive the gripper 10 to complete the gripping action.

[0027] Connecting plates 11 are provided on both sides of the base plate 2. The connecting plates 11 and the base plate 2 are respectively provided with mounting holes. The side end of the connecting plate 11 is connected to the support tube 12. The lower end of the support tube 12 is provided with the foot 13. The upper end of the foot 13 is connected to the guide rod 14. The guide rod 14 is slidably connected in the support tube 12. The upper end of the guide rod 14 is connected to the spring shock absorption assembly 15. The upper end of the spring shock absorption assembly 15 is connected to the support tube 12. The spring shock absorption assembly 15 can effectively reduce the impact force on the UAV during landing.

[0028] In use, this invention involves surveying a forest using a survey camera 101. When litter is observed in the video or when tree sampling is required, the device can be brought close to the object by operating the drone body 1. The drone body 1 is then hovered in the air, and the gripper 10 is controlled remotely. Specifically, servo motor 4 drives the connecting piece 5 to rotate, servo motor 6 drives the electric telescopic push rod 8 to rotate, the electric telescopic push rod 8 drives the third servo motor 9 to move, and the third servo motor 9 drives the gripper 10 to rotate. This allows the gripper 10 to move at multiple angles, thereby grabbing items within a certain distance from the lower end of the drone body 1. After grabbing, the electric telescopic push rod 8 retracts completely, the second servo motor 6 adjusts the electric telescopic push rod 8 to a horizontal angle with the base plate 2, and the first servo motor 4 adjusts the gripper 10 to the side of the box hole 301 of the storage box 3. Then, the electric telescopic push rod 8 pushes the gripper 10 through the box hole 301 into the storage box 3, and then releases the gripper 10. This allows the grabbed items to be placed into the storage box 3, thus completing the cleaning of garbage or sampling of trees.
