The invention relates to the technical field of ship body protection devices, in particular to an unmanned ship seaborne submerged reef obstacle avoidance device which comprises a sonar arranged on the lower side of a ship body and an electric control unit arranged in the ship body, and the electric control unit is used for processing echo signals received by the sonar. When the unmanned ship on the sea is subjected to stormy waves in the task executing process, the sliding blocks and the ship body generate relative displacement through inertia force of the sliding blocks, the sliding blocks are combined with the posture adjusting assemblies to adjust the included angle between the connecting rods and the bottom face of the ship body, and the distance between the sonar and the sea level is adjusted; the position and posture change of the sonar along with the ship body is avoided, so that the deviation of the beam transmitting angle and the beam receiving angle of the sonar is avoided, the horizontal detection range of the sonar is ensured, meanwhile, the change of the form and the intensity of the echo signal caused by the height change of the sonar and the sea level is avoided, and the detection effect of the sonar on a small target is ensured.

    本发明涉及船体防护装置技术领域,具体为一种无人船海上暗礁避障装置,包括设置在船体下侧的声呐和设置在船体内的电控单元,所述电控单元用于处理声呐接收的回波信号,本发明通过设置滑块和位姿调节组件,在海上无人船执行任务过程中受到风浪作用时,通过运用滑块的惯性力,使滑块与船体发生相对位移,且滑块结合位姿调节组件对连杆与船体底面的夹角进行调节,并对声呐与海平面之间的距离进行调节,避免了声呐跟随船体发生位姿变化,从而避免了声呐的波束发射角度和波束接收角度发生偏移,保证了声呐的水平探测范围,同时避免了声呐与海平面的高度变化造成回波信号的形态和强度发生变化,保证了声呐对小目标的探测效果。
