Specific embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5, A photographic device for UAV mapping, which is installed on the bottom surface of a UAV body 1 provided with landing gears 2, and includes: a camera 3 for mapping, a clamping component 5 for clamping the camera 3, and a telescopic component 4 for providing protection to the idle camera 3; The clamping component 5 includes a clamping plate 51, a base 52, a second lead screw 53, an adjustment knob 54, a friction plate 55, a return spring 56, a driving gear 57, a first annular gear 58, a connecting ring 59, a second annular gear 510, a transmission gear 511, an end face gear 512 and a square rod 513; The clamping plate 51 is slidably arranged on the base 52, the base 52 is fixedly installed on the end face of the connecting cylinder 44, the second lead screw 53 is rotatably arranged on the base 52 and is threadedly connected with the clamping plate 51, the adjustment knob 54 is movably arranged on the base 52, the friction plate 55 is fixedly installed on the outer surface of the adjustment knob 54, the two ends of the return spring 56 are respectively fixedly connected with the adjustment knob 54 and the driving gear 57, the driving gear 57 is rotatably arranged inside the base 52 and meshes with the first annular gear 58, the first annular gear 58 is fixedly installed on the outer surface of the connecting ring 59, the connecting ring 59 is rotatably arranged inside the base 52, the second annular gear 510 is fixedly installed on the inner surface of the connecting ring 59, the transmission gear 511 is also rotatably arranged inside the base 52 and meshes with the second annular gear 510, the end face gear 512 is fixedly installed on the end face of the second lead screw 53 and is in meshing transmission connection with the transmission gear 511, the square rod 513 is fixedly installed on the end face of the adjustment knob 54, and the square rod 513 is also slidably connected with the driving gear 57. An anti-slip pad made of rubber is arranged on the side of the clamping plate 51 adjacent to the camera 3. A hexagonal socket is opened on the adjustment knob 54, and the hexagonal socket cooperates with a hexagonal wrench, which is convenient for the user to actually operate to fit the actual application scenario.

[0024] The telescopic component 4 includes a protective cylinder 41, a driving motor 42, a first lead screw 43, a connecting cylinder 44 and a connecting rod 45. The protective cylinder 41 and the driving motor 42 are both fixedly installed on the bottom surface of the UAV body 1. The first lead screw 43 is fixedly installed on the output shaft of the driving motor 42. The connecting cylinder 44 is threadedly connected with the first lead screw 43. The connecting rod 45 is fixedly installed on the connecting cylinder 44. The connecting cylinder 44 is slidably connected with the protective cylinder 41 through the connecting cylinder 44. The driving motor 42 is located inside the protective cylinder 41, and ventilation holes for heat dissipation of the driving motor 42 are opened on the protective cylinder 41. A sliding groove for slidingly cooperating with the connecting rod 45 is opened on the protective cylinder 41, and both ends of the sliding groove are designed with closures, that is, both ends of the sliding groove are closed to prevent the connecting rod 45 from disengaging from any end of the sliding groove during the sliding process, so as to ensure the stable connection and cooperation between the protective cylinder 41 and the connecting rod 45. The height of the protective cylinder 41 is less than the height of the landing gear 2.

[0025] When it is necessary to remove or replace the camera 3 due to its working principle, insert a hex wrench into the adjustment knob 54, and then press down the adjustment knob 54 so that the friction plate 55 is placed inside the inner cavity of the base 52 and does not contact the base 52. At this time, rotate the adjustment knob 54, and the square rod 513 fixed on the adjustment knob 54 is slidably connected to the driving gear 57. The driving gear 57 rotates as the adjustment knob 54 rotates. The first annular gear 58 fixed on the connecting ring 59 meshes with the driving gear 57, and the connecting ring 59 is rotatably arranged inside the base 52. The connecting ring 59 will rotate as the driving gear 57 rotates. The second annular gear 510 is fixed on the connecting ring 59, and the second annular gear 510 also meshes with the transmission gear 511. The transmission gear 511 meshes with and drives the end face gear 512 fixed on the second lead screw 53. Therefore, the second lead screw 53 rotates synchronously. The clamping plate 51 slidably arranged on the base 52 is also threadedly connected to the second lead screw 53. At this time, the clamping plate 51 will slide on the base 52. At the same time, multiple second lead screws 53 are also driven by multiple end face gears 512, transmission gears 511 and the second annular gear 510. Multiple clamping plates 51 slide synchronously, and multiple clamping plates 51 interact to clamp the camera 3. By adjusting the rotation direction of the adjustment knob 54, the connection relationship between the clamping plate 51 and the camera 3 can be changed to adapt to different usage environments. Then pull out the hex wrench from the adjustment knob 54. Under the action of the adjustment knob 54 and the reset spring 56 at both ends, the adjustment knob 54 and the friction plate 55 slide upward. The friction plate 55 contacts the base 52, and the friction lines on the surface of the friction plate 55 cooperate with the base 52 to form a certain frictional force to prevent the adjustment knob 54 and the driving gear 57 from moving, thereby locking the movement of the entire structure and ensuring the fastening degree of the connection between the camera 3 and the base 52 and other structures.

[0026] After the surveying and mapping is completed and it is necessary to retract the camera 3, start the driving motor 42 on the bottom surface of the drone body 1. The first lead screw 43 fixedly connected to the output shaft of the driving motor 42 rotates accordingly. The first lead screw 43 is also threadedly connected to the connecting cylinder 44. The connecting rod 45 fixed on the connecting cylinder 44 is in a sliding connection relationship with the protective cylinder 41, and the protective cylinder 41 is fixed on the drone body 1. Therefore, as the first lead screw 43 rotates, the connecting cylinder 44 will slide, and the connecting cylinder 44 is fixedly connected to the base 52. The base 52 will slide into the protective cylinder 41 along with the connecting cylinder 44, and the camera 3 fixed on the base 52 will slide into the protective cylinder 41 synchronously. Thus, the protective cylinder 41 provides protection for it to prevent the camera 3 from being damaged.
