DETAILED DESCRIPTION

[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.

[0020] like Figure 1-6 As shown, a drone suitable for oblique shooting in complex terrain includes a main body 1, driving components are installed at the four corners of the top of the main body 1, a laser radar 2 is installed on the top of the main body 1, arc frames 3 are rotatably connected on both sides of the main body 1, anti-detachment plug rods 4 are arranged at the bottom of the arc frames 3, a buffer frame 5 is arranged at the bottom of the arc frames 3, an opening is arranged at the top of the buffer frame 5, a buffer spring 6 is arranged inside the opening, and the bottom of the anti-detachment plug rod 4 is inserted into the inside of the opening and connected to the top of the buffer spring 6.

[0021] A driving member 7 is embedded at the bottom of the main body 1, and both sides of the bottom of the main body 1 are connected to a limiting frame 8 by screws. Both sides of the bottom of the driving end of the driving member 7 are connected to a rotating seat 9, and a tilting camera 10 is installed at the bottom of the rotating seat 9. A protective cover 11 is provided on the outer side of the limiting frame 8, and an external thread is provided on the lower side of the protective cover 11. The lower side of the protective cover 11 is threadedly connected to a bottom cover 12.

[0022] The driving assembly includes a connecting rod 13, one end of which is connected to the top of the main body 1, and the other end of the connecting rod 13 is connected to an assembly frame 14. A protective frame 15 is provided on the top of the assembly frame 14, and a driving motor 16 is provided at the bottom of the assembly frame 14. The driving end of the driving motor 16 passes through the assembly frame 14 and is connected to a propeller 17.

[0023] It should be noted that when the UAV is in operation, the drive motor 16 at the bottom of the assembly frame 14 at the other end of the connecting rod 13 is running, which can mobilize the propeller 17 to rotate, so that the UAV can fly in the air; at the same time, the protective frame 15 can protect the propeller 17 to prevent the propeller 17 from being damaged by external impact. During the flight of the UAV, the driving member 7 is running, and the oblique camera 10 can be driven to rotate through the rotating seat 9, so that the multi-angle image acquisition operation of the oblique camera 10 can be realized, wherein the limit frame 8 is used to limit the position of the rotating seat 9 and increase the stability of the rotating seat 9 during the rotation process. In this technical solution, a laser radar 2 and an oblique camera 10 are configured, wherein the laser radar 2 is used to obtain point cloud data of the project location, and the oblique camera 10 is used to obtain real-life information of the project location. The protective cover 11 located outside the oblique camera 10 and the bottom cover 12 under the protective cover 11 are both made of transparent tempered glass, which can protect the oblique camera 10 while ensuring the normal real-life information acquisition of the oblique camera 10.

[0024] After the drone shooting operation is completed, the drone lands. At this time, the bottom of the buffer frame 5 will contact the ground, and through the cooperation of the arc frame 3, the anti-detachment plug rod 4 and the buffer spring 6, the main body 1 is buffered as a whole, which is beneficial to protect the main body 1 and the tilt photography camera 10.

[0025] After the shooting is completed, the operator separates the bolts from the threaded holes and rotates the arc frame 3, then rotates the arc frame 3 to separate the arc frames 3 on both sides of the main body 1, removes the bottom cover 12, separates the two limit frames 8 from the rotating seat 9, then separates the rotating seat 9 from the driving end of the driving member 7, and removes the rotating seat 9 and the tilting camera 10 to facilitate subsequent maintenance and other operations.

[0026] A circle of sealing gasket 18 is provided at the threaded connection between the bottom cover 12 and the lower side of the protective cover 11, which can increase the sealing between the bottom cover 12 and the protective cover 11 and further increase the protection of the protective cover 11 against the tilt photography camera.

Slide blocks corresponding to the slide groove are set on both sides of the rotating seat 9, and the cross-section of the rotating seat 9 is set to an I-shape. Balls 19 are set on the upper and lower sides of the rotating seat 9 to increase the stability of the rotating seat 9 during rotation, and further increase the shooting effect of the oblique camera.

[0028] A plurality of threaded holes are provided at the rotational connection between the arc frame 3 and the main body 1. The upper side of the arc frame 3 is threadedly connected to the threaded holes by bolts. After the lower side of the arc frame 3 is opened, the threaded holes can be threadedly connected to the bolts again to fix the angle of the arc frame 3. A limit block 20 is provided on the upper side of the opening to prevent the anti-dropping plug rod 4 and the top opening of the buffer frame 5 from falling off.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
