(2) starting the driving mechanism to drive the mounting transverse plate 4 to move in the vertical direction, and adjusting the relative height of the rotating mechanism and the water surface;

(3) starting the hydraulic cylinder mechanism 11, so that a piston rod of the hydraulic cylinder mechanism 11 drives the detection column 7 to downwards approach a river bottom sand bed;

(4) and starting the rotating mechanism to drive the hydraulic cylinder mechanism 11 and the detection column 7 to integrally rotate, and then starting the displacement detector 10 and the water level detector 8.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
