The invention relates to the field of topographic survey, in particular to an underwater topographic survey device based on an unmanned ship, which comprises a transducer, and comprises a roll suppression device which comprises a mounting part, a rotating part I and a rotating part II, the rotating part I is rotationally connected to the mounting part so that the rotating part I can rotate in a vertical plane, and the rotating part II is rotationally connected to the rotating part I so that the rotating part I can rotate in a vertical plane; the plane where the first rotating part is located when the first rotating part rotates is perpendicular to the plane where the second rotating part is located when the second rotating part rotates, and the transducer is arranged at the bottom end of the second rotating part; the fluctuation suppression device comprises a suppression plate which is horizontally arranged, and the device has the following beneficial effects that through the roll suppression device, when the ship body rolls laterally, the orientation of the transducer is kept downward all the time, and measurement errors caused by inclination of the ship body are reduced; through the fluctuation suppression device, the fluctuation of the transducer caused by the fluctuation of the ship body is reduced, so that the measurement error caused by the fluctuation of the ship body is reduced, and the measurement precision is improved.

    本发明涉及地形测量领域,特别涉及基于无人船的水下地形勘测装置,包括换能器,包括:侧倾抑制装置,包括安装部、转动部一、转动部二,转动部一转动连接在安装部上,使转动部一能在竖直的平面转动,转动部二转动连接在转动部一上,使转动部二能在竖直的平面转动,转动部一转动时所在的平面与转动部二转动时所在的平面垂直,换能器设置于转动部二的底端;起伏抑制装置,包括水平设置的抑制板,本发明具有以下有益效果:通过侧倾抑制装置,当船体在发生侧倾时,使换能器的朝向保持始终向下,减少了船体倾斜带来的测量误差;通过起伏抑制装置,减少了船体起伏时导致的换能器的起伏,进而减少了船体起伏带来的测量误差,提高了测量的精度。
