Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention:

[0023] A UAV for forest monitoring: It includes a UAV body 1. A monitoring camera 11 is fixedly installed on the surface of the UAV body 1. Wings 12 are arranged on the surface of the UAV body 1. An adjusting mechanism is arranged on the surface of the UAV body 1. The adjusting mechanism includes a fixed rod 2. The fixed rod 2 is fixedly connected to the surface of the UAV body 1. A movable rod 21 is rotatably connected to the surface of the fixed rod 2. The bottom of the movable rod 21 is fixedly connected to a landing gear 22. A fixed block 23 is fixedly connected to the bottom of the UAV body 1. A motor 24 is fixedly connected to the surface of the fixed block 23. A lead screw 25 is fixedly connected to the output shaft of the motor 24. A moving rod 26 is threadedly connected to the surface of the lead screw 25. The bottom of the moving rod 26 is rotatably connected to an adjusting rod 27. One end of the adjusting rod 27 away from the moving rod 26 is rotatably connected to the surface of the landing gear 22. This adjusting mechanism can change the angle of the landing gear 22 in advance before the UAV body 1 lands on a slope, thereby improving the stability of the UAV body 1 when landing on a slope, and further improving the landing safety of the UAV body 1.

[0024] Furthermore, an anti-slip mechanism is provided on the surface of the landing frame 22. The anti-slip mechanism includes a cylinder 3, which is fixedly connected to the surface of the landing frame 22. A connecting plate 31 is fixedly connected to the piston rod of the cylinder 3. A connecting rod 32 is fixedly connected to the surface of the connecting plate 31. Anti-slip nails 33 are fixedly connected to the surface of the connecting rod 32. The anti-slip nails 33 are slidably connected to the surface of the landing frame 22. The ground on some slopes may be relatively smooth, or there may be fallen leaves, loose soil, etc. These conditions reduce the friction between the ground and the landing frame 22, making the UAV body 1 more likely to slide. This anti-slip mechanism can insert the anti-slip nails 33 into the soil, so that the anti-slip nails 33 limit the position of the landing frame 22, and further limit the position of the UAV body 1 on the slope.

[0025] Furthermore, the landing frame 22 rotates on the surface of the fixed rod 2 through the movable rod 21. The landing frame 22 completes the angle adjustment during the rotation process. A threaded hole is provided on the surface of the movable rod 26. The lead screw 25 is threadedly connected to the threaded hole of the movable rod 26. The movable rod 26 is square, and the top of the movable rod 26 is in contact connection with the bottom of the UAV body 1.

[0026] Furthermore, two sets of fixed blocks 23 are provided. The motor 24 drives the lead screw 25 to rotate on the two sets of fixed blocks 23 through the output shaft. The lead screw 25 drives the movable rod 26 to slide on the bottom of the UAV body 1 through rotation. One end of the adjusting rod 27 rotates at the bottom of the movable rod 26 during the sliding process of the movable rod 26. And the end of the adjusting rod 27 away from the movable rod 26 will also rotate on the surface of the landing frame 22 under the restriction of the landing frame 22.

[0027] Furthermore, one end of the adjusting rod 27 moves synchronously with the movable rod 26. The movable rod 26 drives the landing frame 22 to rotate on the fixed rod 2 through the adjusting rod 27 during the moving process. By changing the angle between the landing frame 22 and the slope, the stability of the UAV body 1 on the slope can be made stronger.

[0028] Furthermore, multiple sets of anti-slip nails 33 are provided, and the multiple sets of anti-slip nails 33 are linearly and evenly arranged on the surface of the connecting rod 32. A guiding hole is provided on the surface of the landing frame 22. The anti-slip nails 33 slide on the guiding hole of the landing frame 22. The anti-slip nails 33 are perpendicular to the landing frame 22. The guiding hole of the landing frame 22 ensures the sliding direction of the anti-slip nails 33.

[0029] Further, the connecting plate 31 is in an "L" shape. The cylinder 3 drives the connecting plate 31 to move up and down on the landing frame 22 through the piston rod. The connecting plate 31 drives multiple groups of anti-slip nails 33 to slide up and down on the guide holes of the landing frame 22 through the connecting rod 32. The anti-slip nails 33 are lowered on the landing frame 22 until the anti-slip nails 33 are inserted into the soil. When the UAV body 1 takes off, the anti-slip nails 33 are pulled out of the soil.

[0030] Working principle: The landing frame 22 rotates at one end of the fixed rod 2 through the movable rod 21. The output shaft of the motor 24 drives the lead screw 25 to rotate on the fixed block 23. The lead screw 25 drives the moving rod 26 to slide on the bottom of the UAV body 1 through rotation. During the sliding process of the moving rod 26, the landing frame 22 is driven to rotate on the fixed rod 2 through the adjusting rod 27, so as to complete the adjustment of the angle of the landing frame 22 at the bottom of the UAV body 1, improve the stability of the UAV body 1 during landing on a slope, and further improve the landing safety of the UAV body 1.

[0031] After the landing frame 22 touches the soil on the slope, the piston rod of the cylinder 3 drives the connecting plate 31 to descend. The connecting plate 31 drives multiple groups of anti-slip nails 33 to slide downward on the guide holes of the landing frame 22 through the connecting rod 32, so that multiple groups of anti-slip nails 33 are inserted into the soil of the slope. The anti-slip nails 33 limit the position of the connecting rod 32 in the slope soil, and further limit the position of the UAV body 1 on the slope, avoiding the UAV body 1 from sliding on the slope.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claims involved.
