[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-5 The present invention provides an image acquisition device for crop growth areas, including an unmanned aerial vehicle body 1, and further comprising: The base 2 is fixedly attached to the base plate 3 of the drone body 1. The bottom surface of the base 2 is provided with a mounting bracket 4, and a camera 19 is mounted on the mounting bracket 4. The movable plate 5 is slidably connected to one side of the mounting bracket 4. The mounting bracket 4 is provided with a drive assembly. The drive end of the drive assembly is connected to the movable plate 5 so that the movable plate 5 can move between the outer wall of the mounting bracket 4 and the bottom surface of the camera 19. A cleaning brush 20 is fixedly attached to the side of the movable plate 5 near the camera 19. The mounting bracket 4 is equipped with a control component, the control end of which is connected to the camera 19 so that the camera 19 slides into contact with the cleaning brush 20.

[0020] This invention supports the camera 19 using a mounting bracket 4, and a movable plate 5 is slidably connected to the side wall of the mounting bracket 4. The movable plate 5 is driven and controlled by a drive assembly, allowing it to move between the mounting bracket 4 and the camera 19. When the movable plate 5 is located on the outer side wall of the mounting bracket 4, its structure overlaps with the mounting bracket 4, effectively reducing space occupation and preventing the movable plate 5 from obstructing the image acquisition area of ​​the camera 19. When the movable plate 5 moves to the bottom surface of the camera 19, the control component adjusts the camera 19, causing it to slide into contact with the cleaning brush 20 for cleaning. Furthermore, the movable plate 5, driven by the drive assembly, enhances the contact cleaning effect between the cleaning brush 20 and the camera 19, ensuring image acquisition quality.

[0021] Furthermore, the mounting bracket 4 has a semi-circular plate-shaped structure, and the camera 19 is rotatably fitted inside the recessed side of the mounting bracket 4. An adjustment component is provided on the base 2, and the adjustment end of the adjustment component is connected to the protruding side of the mounting bracket 4 so that the mounting bracket 4 can be rotated with the base 2.

[0022] Using the recessed side of the mounting bracket 4, the camera 19 is rotated and connected inside the mounting bracket 4. The mounting bracket 4 is adjusted by adjusting the adjustment component to adjust the image acquisition angle of the camera 19 and expand the shooting range.

[0023] Specifically, camera 19 uses a common VR panoramic camera.

[0024] Furthermore, the driving components include: The drive seat 6 is fixedly connected to one side of the bottom end of the mounting frame 4. A limit plate 7 is fixedly connected to the side wall of the mounting frame 4. A limit groove is opened on the limit plate 7, and the moving plate 5 is slidably engaged in the limit groove. A miniature servo motor 8 is fixedly connected to the drive base 6. A gear 9 is fixedly connected to the output shaft of the miniature servo motor 8. The gear 9 is rotatably connected in the limiting groove. A toothed plate 10 is fixedly connected to the side wall of the moving plate 5. A toothed groove is opened on the side of the toothed plate 10 near the gear 9. The gear 9 meshes with the toothed groove.

[0025] The micro servo motor 8 drives the gear 9 to rotate, and the gear 9 meshes with the tooth groove. The moving plate 5 is limited by the limiting groove, so that the moving plate 5 moves in the rotation direction of the gear 9, thereby realizing the raising and lowering of the moving plate 5.

[0026] Furthermore, a guide plate 11 is fixedly connected to the side of the movable plate 5 away from the toothed plate 10, and a guide groove 13 is provided on the side wall of the limiting groove. The guide plate 11 and the guide groove 13 are slidably engaged so that the movable plate 5 and the limiting plate 7 do not separate.

[0027] The guide plate 11 and guide groove 13 are used to limit the sliding to prevent the moving plate 5 from separating from the limiting plate 7 during the movement. As the moving plate 5 extends out of the limiting groove, the moving plate 5 moves around the center of the mounting frame 4 to the bottom of the mounting frame 4. The camera 19 rotates downward and slides to contact the cleaning brush 20 for cleaning.

[0028] Furthermore, the control components include a stepper motor 12, which is fixedly connected to the side wall of the mounting bracket 4, and the output shaft of the stepper motor 12 is fixedly connected to the center of one side of the camera 19.

[0029] The rotation angle of the camera 19 is controlled by the stepper motor 12, so that the camera 19 slides downwards and contacts the cleaning brush 20 during cleaning.

[0030] Furthermore, the axes of the toothed plate 10, the limiting plate 7, and the moving plate 5 are parallel to each other.

[0031] The movement of the movable plate 5 is ensured to accurately circle the center of the mounting bracket 4, so that the cleaning brush 20 is moved below the camera 19.

[0032] Furthermore, the adjusting component includes a rotating motor 14, which is fixedly connected to the base 2. The output shaft of the rotating motor 14 is fixedly connected to a first bevel gear 15, and a second bevel gear 16 meshes with the first bevel gear 15. A rotating rod 17 is fixedly connected to the axis of the second bevel gear 16, and the rotating rod 17 extends vertically downward and is fixedly connected to the protruding side of the mounting bracket 4.

[0033] The rotation of the motor 14 drives the first bevel gear 15 and the second bevel gear 16 to achieve rotational adjustment of the mounting bracket 4, thereby adjusting the shooting angle of the camera 19.

[0034] Furthermore, one side of the drive seat 6 extends away from the mounting bracket 4, and the bottom surface of the extended portion of the drive seat 6 is fixed with a lamp plate 18.

[0035] The drive seat 6 forms a structural protrusion, and the light plate 18 is fixed to the part of the structural protrusion. The light plate 18 is arranged in the forward direction of the unmanned aerial vehicle body 1 to provide supplementary lighting for the image acquisition of the camera 19.

[0036] Furthermore, the movable plate 5 has an arc-shaped structure, and the movable plate 5 and the mounting frame 4 are arranged at the same center. The length of the movable plate 5 is greater than half the length of the mounting frame 4.

[0037] The arc-shaped mounting bracket 4 and the movable plate 5 are arranged concentrically. As the movable plate 5 moves, it can extend out of the limiting plate 7 and move along with the cleaning brush 20 to below the camera 19.

[0038] This invention provides the working principle of an image acquisition device for crop growth areas: The drone body 1 moves the camera 19 to collect images. When a blemish appears in the image, the stepper motor 12 drives the camera 19 to rotate, pointing the lens downwards. Then, the micro servo motor 8 rotates the gear 9, causing the moving plate 5 to move along the slot of the limiting groove, and the cleaning brush 20 moves to below the camera 19. Due to the flexible expansion characteristics of the cleaning brush 20, the camera 19 slides into contact with the cleaning brush 20. The micro servo motor 8 reciprocates to clean the camera 19. After cleaning, the moving plate 5 is returned to the limiting groove.
