Description

Technical Field

[0001] This utility model relates to the field of forestry surveys, and in particular to a forestry survey drone. Background Technology

[0002] An existing patent (publication number: CN215851884U) proposes a forestry survey drone. A sleeve is fixedly connected to a connecting block, a first motor is fixedly connected to the connecting block, a first rotating shaft is directly connected to the first motor, a rotating mechanism is fixedly connected to the first rotating shaft and also to the sleeve, a U-shaped frame is fixedly connected to the rotating mechanism, a second motor is fixedly connected to the U-shaped frame, a second rotating shaft is directly connected to the second motor and rotatably connected to the U-shaped frame, and a camera mechanism is fixedly connected to the second rotating shaft. However, in this device, "the rubber block is fixedly connected to the fourth telescopic rod and located on one side of the fourth telescopic rod." The bottom of the rubber block is flat. In complex ground conditions, this may result in insufficient contact area between the bottom of the rubber block and the ground after landing, affecting the safety and stability of subsequent support. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a forestry survey drone that allows movable outriggers to automatically adjust their tilt angle based on the unevenness of the ground during landing. This adapts to different terrain conditions, ensuring sufficient contact area between the outriggers and the ground, thus guaranteeing support stability. This enables the drone to land on complex terrain within forest areas, ensuring a safer and more stable landing when the drone needs to land in forest areas due to insufficient power or other reasons.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A forestry survey drone includes a drone body, an electric telescopic rod, an upper traction block, a lower traction rod, movable feet, a traction spring, a drive motor body for a turntable, a turntable wheel, a striking plate, a bird-startling bell, a camera mounting base, and a forestry survey camera. The bottom of the drone body is connected to the camera mounting base, and the bottom of the camera mounting base is connected to the forestry survey camera. The bottom of the drone body has main support legs, which are distributed on both sides of the camera mounting base. The bottom of the main support legs has a telescopic rod mounting platform, and the side of the telescopic rod mounting platform is fixedly connected to the electric telescopic rod. The bottom of the electric telescopic rod has a telescopic tube, and the side of the telescopic tube has movable seat bearing rods. Three movable seat bearing rods are evenly arranged around the telescopic tube. The side of the movable seat bearing rod has a foot bearing column, and the three sets of foot bearing columns together form a locking block mounting groove. The top of the foot bearing column has an upper traction block connecting groove, and the bottom of the foot bearing column has a foot connecting groove. The bottom of the movable seat bearing rod is provided with a movable foot, and the top of the movable foot has a foot connector and a lower traction rod mounting base, which is located on the side of the foot connector.

[0006] The support leg connector is rotatably connected to the support leg connecting groove. An upper traction block is provided on the side of the movable seat bearing rod. The top of the upper traction block has an upper traction block mounting head, which is rotatably connected to the upper traction block connecting groove. The bottom of the upper traction block has an upper traction slide rod. The top of the movable support leg is provided with a lower traction rod, which has a lower traction rod mounting head at its bottom. The lower traction rod mounting head is rotatably connected to the lower traction rod mounting seat. The upper traction slide rod is adapted to the lower traction rod and is connected to the lower traction rod. The upper traction slide rod slides inside the lower traction rod. The upper traction slide rod and the lower traction rod are connected by a traction spring. The bottom of the telescopic rod mounting platform has a locking block mounting post.

[0007] Beneficial effects: 1. During forestry surveys, when a temporary landing is required, the telescopic tube extends and the locking claw disconnects from the locking claw connecting groove. At this time, the movable outrigger can move freely. During landing, the movable outrigger automatically adjusts its tilt angle according to the unevenness of the ground to adapt to different uneven ground, ensuring the contact area between the outrigger and the ground, ensuring support stability, and enabling the drone body to land on relatively complex terrain inside the forest. This ensures a safer and more stable landing when the drone body needs to land inside the forest due to insufficient power or other reasons.

[0008] 2. In this utility model, the upper traction slide rod and the lower traction rod are connected by a traction spring. After the locking pawl is released from locking the locking pawl connecting groove, the traction spring can pull the lower traction rod and the upper traction slide rod to prevent the movable outrigger from deflecting excessively. This avoids the movable outrigger from deflecting too much and causing the tip of the movable outrigger to contact the ground first, affecting the subsequent landing effect.

[0009] 3. In the retracted state of the telescopic tube of this utility model, the locking claw is inserted into the locking claw connecting groove, so that the movable foot is completely fixed, thereby keeping the movable foot completely fixed during the flight of the UAV body and avoiding the irregular movement of the movable foot from affecting the flight stability of the UAV body 1.

[0010] 4. The side of the actuation wheel of this utility model is provided with a striking plate and a bird-scare bell. When the actuation wheel drive motor drives the actuation wheel to rotate, the actuation plate moves the striking plate, causing the striking head of the striking plate to strike the bird-scare bell to produce a sound, thereby driving away the surrounding birds or other animals, avoiding interference from birds or other animals to the survey operation or threats to the main body of the UAV, and increasing the safety of the UAV in the survey process.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0022] Example 1:

[0023] A forestry survey drone includes a drone body 1, an electric telescopic rod 6, an upper traction block 8, a lower traction rod 9, movable support legs 12, a traction spring 23, a drive motor body 26 for a turntable wheel 27, a striking plate 29, a bird-startling bell 32, a camera mounting base 33, and a forestry survey camera 34. The bottom of the drone body 1 is connected to the camera mounting base 33, and the bottom of the camera mounting base 33 is connected to the forestry survey camera 34. The bottom of the drone body 1 has main support legs 3, which are distributed on both sides of the camera mounting base 33. The main support leg 3 has a telescopic rod mounting platform 4 at its bottom. An electric telescopic rod 6 is fixedly connected to the side of the telescopic rod mounting platform 4. The electric telescopic rod 6 has a telescopic tube 601 at its bottom. During forestry surveys, when a temporary landing is required, the telescopic tube 601 extends, and the locking claw 17 disconnects from the locking claw connecting groove 18. At this time, the movable support leg 12 can move freely. During landing, the movable support leg 12 automatically adjusts its tilt angle according to the unevenness of the ground to adapt to different terrain conditions, ensuring the contact area between the support leg and the ground and guaranteeing support stability. This allows the UAV body 1 to land on relatively complex terrain within the forest, ensuring a safer and more stable landing when the UAV body 1 needs to land within the forest due to insufficient power or other reasons. The telescopic tube 601 has three movable seat bearing rods 7 on its side, evenly arranged around the telescopic tube 601. When the telescopic tube 601 is retracted, the locking claw 17 inserts into the locking claw connecting groove 18, completely fixing the movable support leg 12. This ensures that the movable support leg 12 remains completely fixed during the flight of the UAV body 1. To prevent irregular movement of the movable support leg 12 from affecting the flight stability of the UAV body 1, the movable support rod 7 has a support leg support column 19 on its side. The three sets of support leg support columns 19 together form a locking block mounting groove 20. The top of the support leg support column 19 has an upper traction block connecting groove 15, and the bottom of the support leg support column 19 has a support leg connecting groove 14. The bottom of the movable support rod 7 is provided with a movable support leg 12. The top of the movable support leg 12 has a support leg connector 13 and a lower traction rod mounting seat 11. The lower traction rod mounting seat 11 is located on the side of the support leg connector 13.

[0024] Example 2:

[0025] The support leg connector 13 of this utility model is rotatably connected to the support leg connecting groove 14. An upper traction block 8 is provided on the side of the movable seat bearing rod 7. The top of the upper traction block 8 has an upper traction block mounting head 21, which is rotatably connected to the upper traction block connecting groove 15. The bottom of the upper traction block 8 has an upper traction slide rod 22. The top of the movable support leg 12 is provided with a lower traction rod 9, and the bottom of the lower traction rod 9 has a lower traction rod mounting head 10, which is rotatably connected to the lower traction rod mounting seat 11. The upper traction slide rod 22 is adapted to the lower traction rod 9 and connects to the lower traction rod 9. The upper traction slide 22 slides inside the lower traction rod 9. The upper traction slide 22 and the lower traction rod 9 are connected by a traction spring 23. After the locking claw 17 releases its lock on the locking claw connecting groove 18, the traction spring 23 can pull the lower traction rod 9 and the upper traction slide 22 to prevent the movable outrigger 12 from deflecting excessively. This avoids the movable outrigger 12 deflecting too much and causing the tip of the movable outrigger 12 to contact the ground first, affecting the subsequent landing effect. The bottom of the telescopic rod mounting platform 4 has a locking block mounting post 5.

[0026] Example 3:

[0027] The locking block mounting post 5 of this utility model has a locking block 16 at the bottom and a locking claw 17 on the side of the locking block 16. The locking claw 17 is adapted to the locking block mounting groove 20 and is connected to the locking block mounting groove 20. The locking claw 17 slides inside the locking block mounting groove 20. The support foot connector 13 has a locking claw connecting groove 18 on the side. The locking claw 17 is adapted to the locking claw connecting groove 18 and is connected to the locking claw connecting groove 18. The locking claw 17 is inserted into the locking claw connecting groove 18. The drone body 1 has a toggle wheel drive motor 24 and a striking plate mounting platform 28 on the side. The striking plate mounting platform 28 is located on the side of the toggle wheel drive motor 24.

[0028] Example 4:

[0029] The toggle wheel drive motor 24 of this invention has a toggle wheel motor groove 25 on the side facing the striking plate mounting platform 28. The toggle wheel drive motor body 26 is inserted into and fixed inside the toggle wheel motor groove 25. The drive shaft of the toggle wheel drive motor body 26 is fixedly connected to the toggle wheel 27. The toggle wheel 27 has a toggle plate 35 on its side, and three sets of toggle plates 35 are evenly arranged around the toggle wheel 27. The toggle wheel 27 is provided with a striking plate 29 and a bird-startling bell 32 on its side. When the toggle wheel drive motor body 26 drives the toggle wheel... When 27 rotates, the actuating plate 35 actuates the striking plate 29, causing the striking head 31 of the striking plate 29 to strike the bird-startling bell 32, thereby driving away surrounding birds or other animals and preventing birds from interfering with the survey operation or threatening the UAV body 1 itself, thus increasing the safety of the UAV body 1 during the survey process. The striking plate mounting platform 28 is provided with the striking plate 29 on the side facing the actuating wheel motor groove 25, and the striking plate 29 has a striking plate mounting head 30 on the side facing the striking plate mounting platform 28.
