Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a grassland vegetation monitoring unmanned aerial vehicle. Background Art

[0002] A grassland vegetation monitoring unmanned aerial vehicle is a kind of unmanned aerial vehicle specially designed for monitoring the grassland ecosystem and the growth state of plants. It calculates the vegetation coverage of the grassland area through image analysis, and can identify different plant species to help study plant diversity and distribution. It combines aerial photography, remote sensing technology and data analysis capabilities, and can efficiently and accurately collect and analyze vegetation-related information.

[0003] Many existing unmanned aerial vehicles will be contaminated with a lot of dust in the air during flight. This dust will block the camera, resulting in unclear images and unable to monitor the grassland ecosystem and other situations. Usually, the operator needs to lower the unmanned aerial vehicle to manually clean this dust. At the same time, the camera angle of the unmanned aerial vehicle is usually fixed during flight and it is difficult to flexibly adjust according to different detection requirements, which limits the comprehensiveness of its detection.

A camera is provided inside the protective shell 302. Cleaning components for cleaning the protective shell 302 are provided on both sides of the protective shell 302; the grassland vegetation is monitored by the camera, and the camera is protected by the protective shell 302 to prevent dust from blocking the camera during flight.

[0026] In one embodiment, as Figure 2 and Figure 3 shown, the cleaning component includes an electric push rod 401. A connecting rod 402 is installed at the output end of the electric push rod 401. A scraping plate 403 is fixedly connected to the outer wall of the connecting rod 402. One side of the scraping plate 403 is slidably connected to the protective shell 302. An adjusting component for adjusting the irradiation angle of the camera is provided on one side of the protective shell 302; by starting the electric push rod 401, the connecting rod 402 is driven to move up and down, thereby driving the scraping plate 403 to move up and down on the surface of the protective shell 302, achieving the effect of cleaning the dust on the surface of the protective shell 302.

[0027] In one embodiment, as Figure 2 and Figure 3 shown, the adjusting component includes a fixed frame 501. A motor 502 is installed on the inner top wall of the fixed frame 501. A worm 503 is installed at the output end of the motor 502. The worm 503 meshes with a worm gear 504. A rotating rod 505 is fixedly connected inside the worm gear 504. The rotating rod 505 is fixedly connected to the protective shell 302. Both ends of the rotating rod 505 are rotatably connected to the support frame 301; by starting the motor 502, the worm 503 is driven to rotate. The worm 503 drives the worm gear 504 meshing with it to rotate, thereby driving the rotating rod 505 to rotate inside the support frame 301. The rotating rod 505 drives the protective shell 302 to rotate, so as to appropriately adjust the irradiation angle of the camera and make the monitoring range more comprehensive.

[0028] In one embodiment, as Figure 1 shown, rubber pads are installed on one side of the fuselage 100 close to the protective shell 302 and at the bottom of the frame 200; by providing the rubber pads, when the fuselage 100 encounters inevitable obstacles during flight, the rubber pads can prevent the fuselage 100 from being severely damaged.
