[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a UAV for forestry planning, including: a UAV body 1, a protective frame 2 is fixedly connected to the bottom center of the UAV body 1, the inner surfaces of both sides of the protective frame 2 are rotatably connected to the rotating shaft 6, a rotating frame 4 is fixedly connected between the end faces of the two rotating shafts 6, a gear 8 is fixedly connected to the outer surface of one rotating shaft 6, a fixed block 7 is fixedly connected to the inner wall of one side of the protective frame 2, a multi-stage electric push rod 11 is fixedly connected to the outer surface of one side of the fixed block 7, a fixed plate 12 is fixedly connected to the driving end of the multi-stage electric push rod 11, a tooth row 13 is fixedly connected to the outer surface of the fixed plate 12, the position of the tooth row 13 matches the position of the gear 8, the inner surface of the tooth row 13 is meshed with the outer surface of the gear 8, the inner surface of the protective frame 2 is fixedly connected to the sealing gasket 9 at the bottom, and the outer surface of the sealing gasket 9 is matched with the outer surface of the rotating frame 4. The inner surface of the rotating frame 4 is fixedly connected to a camera 5.

[0024] The effect achieved by the entire embodiment 1 is that the drone body 1 is started to take off and fly high above the forestry to be planned, and then the camera 5 is used to assist the forestry planning needs. When the planning is completed and the return trip is made, the multi-stage electric push rod 11 can be started to retract its driving end toward the inner wall, thereby driving the fixed plate 12 and the gear row 13 to move. The gear row 13 and the gear 8 are meshed, so that when the gear row 13 moves, it will drive the gear 8 to rotate, thereby driving one of the rotating shafts 6 to rotate, and through the setting of the other rotating shaft 6, the rotating frame 4 will rotate 180 degrees along the two rotating shafts 6. The travel of the multi-stage electric push rod 11 and the gear row 13 are matched with the rotating shaft 6. When the multi-stage electric push rod 11 is extended to its maximum stroke, the rotating frame 4 will rotate 180 degrees in the forward direction along the rotating shaft 6. When the multi-stage electric push rod 11 is retracted to its maximum stroke, the rotating frame 4 will rotate 180 degrees in the reverse direction along the rotating shaft 6, thereby driving the camera 5 to move to the inside of the protective frame 2 for protection. Rotating the camera 5 into the protective frame 2 can reduce physical damage to the camera 5, thereby extending the service life of the camera 5. At the same time, when the camera 5 is protected by the protective frame 2, with the assistance of the internal sealing gasket 9 of the protective frame 2 and the rotating frame 4, dust can be prevented from entering the inside of the protective frame 2, thereby reducing dust adhesion, keeping the lens clean, and ensuring the shooting quality of the camera 5 during the next flight.

[0025] Embodiment 2, as Figure 1-Figure 5 As shown, the bottom of the drone body 1 is fixedly connected with brackets 3 near both sides, the bottoms of the two brackets 3 are symmetrically fixedly connected with dampers 14, the outer surfaces of the multiple dampers 14 are sleeved with springs 16, the multiple dampers 14 are divided into two groups, the bottoms of the two groups of dampers 14 are fixedly connected with support plates 15, the tops of the multiple springs 16 are respectively fixedly connected to the bottoms of the two brackets 3, and the bottoms of the multiple springs 16 are respectively fixedly connected to the tops of the two support plates 15.

[0026] The effect achieved by the entire embodiment 2 is that when the drone body 1 is landing, with the assistance of the spring 16 and the damper 14 arranged on the bracket 3, the impact force of the drone body 1 during landing is effectively absorbed and buffered, providing a smoother landing, reducing damage to the drone body 1 and the camera 5, thereby extending the service life of the drone.

[0027] Working principle: start the drone body 1 to take off and fly at a high altitude above the forestry to be planned, then use the camera 5 to assist the forestry planning needs. When the planning is completed and the return trip is made, the multi-stage electric push rod 11 can be started to retract its driving end toward the inner wall. The setting of the fixed block 7 makes the multi-stage electric push rod 11 more stable during use, thereby driving the fixed plate 12 and the gear row 13 to move. The gear row 13 and the gear 8 are meshed, so that when the gear row 13 moves, it will drive the gear 8 to rotate, thereby driving one of the rotating shafts 6 to rotate, and through the setting of the other rotating shaft 6, the rotating frame 4 will rotate 180 degrees along the two rotating shafts 6. The strokes of the multi-stage electric push rod 11 and the gear row 13 are matched with the rotating shaft 6. When the multi-stage electric push rod 11 is extended to the maximum stroke, the rotating frame 4 will rotate 180 degrees in the forward direction along the rotating shaft 6. When the electric push rod 11 is retracted to its maximum stroke, the rotating frame 4 will rotate 180 degrees in the opposite direction along the rotating shaft 6, thereby driving the camera 5 to move to the inside of the protective frame 2 for protection. Rotating the camera 5 into the protective frame 2 can reduce physical damage to the camera 5, thereby extending the service life of the camera 5. At the same time, when the camera 5 is protected by the protective frame 2, with the assistance of the internal sealing gasket 9 of the protective frame 2 and the rotating frame 4, dust can be prevented from entering the inside of the protective frame 2, reducing dust adhesion, keeping the lens clean, and ensuring the shooting quality of the camera 5 during the next flight. When the drone body 1 is landing, with the assistance of the spring 16 and the damper 14 set on the bracket 3, the impact force of the drone body 1 during landing is effectively absorbed and buffered, providing a smoother landing, reducing damage to the drone body 1 and the camera 5, thereby extending the service life of the drone.

[0028] The wiring diagram of the drone body 1, camera 5 and multi-stage electric push rod 11 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the drone body 1, camera 5 and multi-stage electric push rod 11 are no longer explained in detail.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
