During the disassembly process, if the operation is improper, it may cause damage to the main body of the unmanned aerial vehicle or loss of the disassembled parts, posing a safety hazard. In view of the above defects, the present utility model is proposed. Content of the Utility Model

[0026] The following further elaborates the present utility model in combination with the accompanying drawings and embodiments for the above-mentioned and additional technical features and advantages of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Embodiment

[0027] As Figures 1-5 shown, the present utility model provides a fixed-point patrol UAV for outdoor surveying and mapping, including a UAV main body 1, four groups of UAV propeller blades 2 are arranged on the UAV main body 1, two groups of support frames 3 are symmetrically connected to the bottom end of the UAV main body 1, a disassembling part 4 is arranged at the bottom end of the UAV main body 1, the UAV main body 1 is fixedly connected to the support frame 3 through the disassembling part 4, and a mounting part 5 is arranged on the disassembling part 4;

[0028] The UAV main body 1 is pulled through the disassembling part 4 for disassembly and installation, and a camera device is installed in the mounting part 5.

[0029] The disassembling part 4 includes an auxiliary plate 41 installed on the side wall of the support frame 3, a chute 42 opened on the inner wall of the auxiliary plate 41, a slide block 43 slidably connected to the inner wall of the chute 42, a limiting rod 44 installed and connected to the slide block 43 and placed in the auxiliary plate 41, a spring 45 wound around the outer wall of the limiting rod 44, a pull rod 46 connected to the outer end of the limiting rod 44, an inserting rod 47 installed on the outer wall of the bottom end of the support frame 3, an inserting slot 48 opened in the support frame 3, and a limiting slot 49 opened in the inserting rod 47;

[0030] Below the auxiliary plate 41 is connected with a mounting member 5;

[0031] The mounting member 5 includes a mounting frame 51 connected to the outer wall of the bottom end of the auxiliary plate 41, a shooting through-hole 52 opened on the mounting frame 51, a hinged plate 53 arranged on the side wall of the mounting frame 51, a placing plate 54 connected to the hinged plate 53, a fastening bolt 55 threadedly connected to the hinged plate 53, and a mounting hole 56 opened on the placing plate 54;

[0032] When the user needs to disassemble the support frame 3 for maintenance and repair, only need to pull the pull rod 46 outwards, so that the pull rod 46 drives the limit rod 44 to slide outwards through the chute 42 in the slider 43. One end of the spring 45 is connected to the outer wall of the slider 43, and the other end of the spring 45 is connected to the inner wall of the auxiliary plate 41. During the sliding process, the spring 45 is squeezed to generate deformation until the limit rod 44 is completely removed from the limit groove 49, releasing the limit between the support frame 3 and the drone body 1. At this time, the drone body 1 can be pulled upwards or the support frame 3 can be pulled downwards to separate the insertion rod 47 from the insertion slot 48 to complete the disassembly. The installation is the same by operating in the reverse direction;

[0033] Among them, two groups of chutes 42 are symmetrically arranged, and the length of each group of chutes 42 is set to be greater than the length of the limit groove 49; the symmetrical arrangement of the chutes 42 and the limit rods 44 helps to maintain the alignment and stability between the drone body 1 and the support frame 3. The symmetrical design can ensure that the drone body will not tilt or shake due to imbalance during the disassembly and installation process.

[0034] Two groups of limit rods 44 are symmetrically arranged in the auxiliary plate 41. The caliber of each group of limit rods 44 is set to be equal to the caliber of the limit groove 49. Two groups of insertion rods 47 are symmetrically arranged. The caliber of each group of insertion rods 47 is set to be equal to the insertion slot 48. The caliber of the limit rod 44 is set to be equal to the caliber of the limit groove 49. This can ensure that the limit rod will not accidentally fall off or deviate from the correct path when moving in the chute, reducing the possibility of misoperation. The symmetrical arrangement can disperse the force and reduce the pressure on a single component, thereby improving the strength and durability of the overall structure;

[0035] The user can loosen the fastening bolt 55 to make the placing plate 54 rotate and open on the side wall of the mounting frame 51 through the hinged plate 53. After the two placing plates 54 are opened from the bottom end of the mounting frame 51, the imaging device can be placed into the two mounting frames 51. The camera shoots outwards through the shooting through-hole 52, and then rotates the placing plate 54 to close the bottom end, and fixes it by tightening the fastening bolt 55;

[0036] Among them, the placement plate 54 is rotatably connected to the side wall of the installation frame 51 through the hinge plate 53. The fastening bolt 55 fixes or releases the fixation of the placement plate 54 by screwing in or out. Through the design of the hinge plate 53 and the fastening bolt 55, the placement plate 54 can be quickly opened and closed, which provides convenience for the installation and disassembly of the camera device. This design enables users to easily replace or maintain the camera device without the need for complex tools or long operations;

[0037] There are two groups of placement plates 54 arranged symmetrically. Two groups of mounting holes 56 are symmetrically arranged on each group of placement plates 54. The camera device is fixed by screwing bolts into the mounting holes 56. The mounting holes 56 are symmetrically arranged on each group of placement plates 54. Such a design can ensure that the camera device is more stable when fixed by bolts. The multi-point fixation can reduce the vibration of the camera device during flight and improve the clarity and accuracy of the mapping images.

[0038] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
