The invention discloses an underwater sonar search machine and an underwater search system, the underwater sonar search machine comprises a search machine body, a propulsion unit, a search unit and a pressurized-water wing unit, the search machine body is of a rotary body structure, the propulsion unit, the search unit and the pressurized-water wing unit are all arranged on the search machine body, and the search unit is used for searching, detecting and imaging an underwater target; the propelling unit is used for driving the searching machine body to move in the longitudinal direction and the vertical direction and controlling the pitching angle, the roll angle and the course angle of the searching machine body. The water pressing wing unit is arranged on the back of the searching machine body, and the included angle between the water pressing wing unit and the longitudinal direction of the searching machine body is automatically adjusted according to the condition of water flow resistance, so that the searching machine body is vertically stressed in a balanced mode and sails at the fixed depth. A frame carrier is omitted, and the sailing capacity is improved; the pressurized water wing unit is additionally arranged to achieve autonomous adjustment of the navigation depth of the searching machine in a dragging cruise mode, it is guaranteed that the searching machine navigates at the fixed depth during high-speed navigation and does not float upwards, and the deep sea searching requirement is met.
本发明公开一种水下声呐搜索机和水下搜索系统,包括搜索机本体、推进单元、搜索单元和压水翼单元,搜索机本体为回转体结构,推进单元、搜索单元和压水翼单元均设置于搜索机本体,搜索单元用于对水下目标进行搜索探测成像;推进单元用于驱动搜索机本体沿纵向和竖向移动,并对搜索机本体的仰俯角、横滚角和航向角进行控制;压水翼单元设置于搜索机本体的背部,并根据受到水流阻力的情况,自动调节与搜索机本体纵向之间的夹角,以使搜索机本体竖向受力平衡而航行在固定深度。本发明取消框架载体,提高航行能力;增设压水翼单元实现拖拽巡航模式下搜索机航行深度的自主调节,保证高速航行时搜索机在固定深度航行,而不上浮,满足深海搜索需求。
