The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model. It should be pointed out that the following detailed descriptions are all exemplary and are intended to provide further explanation of the utility model.

[0014] As attached Figure 1 As shown, an embodiment of the utility model relates to a drone for river channel mapping, comprising: a main body 1, a cantilever 2, a motor 3, a propeller 4, a bracket 5, a connecting frame 6, a connecting plate 7, an electric push rod 8, and a camera 9. The number of the cantilever 2 is multiple, specifically 4, 6 or 8, one end of the cantilever 2 is fixed to the side of the main body 1, the other end of the cantilever 2 is fixed to the motor 3, and the output shaft of the motor 3 is fixedly connected to the propeller 4. The main body 1 is fixedly connected above the bracket 5. The two ends of the bracket 5 are respectively pivotally connected to one end of the connecting frame 6, and the other end of the connecting frame 6 is fixedly connected to the upper surface of the connecting plate 7. The camera 9 is fixedly installed on the lower surface of the connecting plate 7. One end of the electric push rod 8 is pivotally connected to the bracket 5, and the other end of the electric push rod 8 is pivotally connected to the connecting plate 7.

[0015] The electric push rod 8 can be extended or shortened, thereby driving the connecting plate 7 and the camera 9 to rotate around the pivot axis at which the connecting frame 6 is pivotally connected to the bracket 5 .

[0016] As attached Figure 2As shown, the main body 1 is equipped with a main controller 11, a wireless communication module 12, and a battery 13. The main controller 11 is respectively connected to the wireless communication module 12, the motor 3, the electric push rod 8, and the camera 9. The battery 13 is respectively connected to the main controller 11, the wireless communication module 12, the motor 3, the electric push rod 8, and the camera 9.

[0017] The camera 9 is used to capture river channel mapping images and send them to the main controller 11 .

[0018] The wireless communication module 12 is used to receive control commands sent by the ground control station and send them to the main controller 11, and to send river channel mapping images from the main controller 11 to the ground control station.

[0019] The main controller 11 is used to receive the river channel mapping images taken by the camera 9 and control the motor 3 and the electric push rod 8.

[0020] The bracket 5 extends two landing gears 51 downward. The left and right ends of the bracket 5 are respectively provided with connecting arms 52 extending downward, and the lower ends of the connecting arms 52 are pivotally connected to the upper end of the connecting frame 6. The left and right sides of the bracket 5 are respectively provided with push rod arms 53 extending downward, and the lower end of each push rod arm 53 is pivotally connected to the upper end of an electric push rod 8.
