Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle detection, and in particular to an unmanned aerial vehicle for detecting vegetation coverage in desert areas and a method of using the unmanned aerial vehicle. Background Art

[0002] Drone exploration is a technology that uses unmanned aerial vehicles (UAVs) to conduct geographical, geological and environmental surveys. Drones are used to detect vegetation cover in desert areas mainly to monitor and analyze the vegetation conditions in desert areas. By shooting from different angles, drones can obtain more comprehensive and accurate vegetation information, which is helpful for subsequent data processing and analysis. There are often tumbleweeds in the desert. Tumbleweeds will form rolling "grass balls" under the action of strong winds. When drones are conducting low-altitude detection, if the drones encounter these obstacles while flying at low altitudes, collision accidents will occur. When conducting drone exploration in areas where tumbleweeds are rampant, operators need to control the flight altitude and speed of the drone more carefully to avoid collisions with tumbleweeds, which undoubtedly increases the difficulty and complexity of the operation.

[0031] The operation steps of the method for using a drone for vegetation coverage detection in desert areas are as follows:

[0032] Step 1: Control the drone 1 to fly to the top of the tumbleweed;

[0033] Step 2: Start the servo motor 18, the servo motor 18 rotates to drive the movable column 13 to rotate, the movable column 13 drives the special-shaped disk 16 to rotate, and when the special-shaped disk 16 rotates, it drives the gear disk 25 to rotate through the trigger bar 15;

[0034] Step 3: When the gear plate 25 rotates, it drives the start block 27 to move toward the inside of the placement shell 28.

[0037] Step 6: When the positioning plate 7 drives the rotating bar 54 to reach the position corresponding to the trigger column 42, the rotating bar 54 is blocked by the corresponding trigger column 42 and then rotates to change its position, and then the triangular block part on the rotating bar 54 rotates to push the telescopic column 49 to move toward the inside of the fixed shell 48, and then the second spring 50 is compressed. When the triangular block part of the rotating bar 54 rotates to the highest point, the compressed second spring 50 rebounds and drives the telescopic column 49 to reset. When the telescopic column 49 is reset, it drives the telescopic column 49 to impact the triangular part of the rotating bar 54, and then the rotating bar 54 rotates rapidly to push away the nearby tumbleweeds.

[0038] Working principle:

[0039] When the drone body 1 is needed to detect vegetation coverage in desert areas and encounters tumbleweed obstruction, the drone body 1 is flown to the top of the tumbleweed, and the servo motor 18 is started. When the servo motor 18 rotates, the special-shaped disk 16 is driven to rotate through the movable column 13. When the position with a larger radius of the special-shaped disk 16 rotates to a position corresponding to the first limiting column 17, the first limiting column 17 drives the connecting bar 12 to tilt toward the position of the positioning bar 9. When the connecting bar 12 tilts, the movable bar 10 is driven downward through the connecting column 11. When the movable bar 10 moves toward the lower end, the starting block 27 enters the interior of the placement shell 28, and the starting block 27 drives The start column 29 moves toward the tumbleweed position at the lower end, and then the tension spring 30 is stretched. When the tension spring 30 is stretched, the start column 29 moves toward the lower end. When the moving block 36 leaves the position of the telescopic slot 33, the compressed first spring 35 rebounds and drives the moving block 36 to open and fix the tumbleweed. Then, when the special-shaped disk 16 rotates, it drives one end of the trigger bar 15 to rotate. When one end of the trigger bar 15 rotates, it drives the other end of the trigger bar 15 to extend along the position of the moving bar 21. When the trigger bar 15 extends, it pushes the pulled tumbleweed away. When the stretched trigger bar 15 rotates and resets, the stretched tension spring 30 rebounds, and then the tension spring 30 drives the start column 29 when it rebounds. The movable block 36 is reset, and then the movable block 36 moves toward the position of the telescopic slot 33. When the movable block 36 reaches the telescopic slot 33, the two movable blocks 36 are compressed and reset. When the trigger bar 15 is moving, the movable bar 10 moves toward the lower end, and the blocking column 26 releases the limit on the gear plate 25. The trigger bar 15 drives the meshing gear plate 25 to rotate through a plurality of tooth blocks 22, and then the gear plate 25 drives the second transmission shaft 24 to rotate when rotating. When the second transmission shaft 24 rotates, it drives the worm 43 to rotate through the worm gear 38. When the worm 43 rotates, it drives the threaded column 44 to rotate through the bevel gear 45. When the threaded column 44 rotates, it drives the threaded block 46 upward. When the screw block 46 rises, it drives the placement plate 47 to rise. When the placement plate 47 drives the rotating bar 54 to reach the position corresponding to the trigger column 42, the rotating bar 54 is blocked by the corresponding trigger column 42 and then rotates to change its position. Then, the triangular block part on the rotating bar 54 rotates to push the telescopic column 49 to move toward the inside of the fixed shell 48, and then the second spring 50 is compressed. When the triangular block part of the rotating bar 54 rotates to the highest point, the compressed second spring 50 rebounds and drives the telescopic column 49 to reset. When the telescopic column 49 is reset, it drives the telescopic column 49 to impact the triangular part of the rotating bar 54, and then the rotating bar 54 rotates rapidly to push away the nearby tumbleweeds.
