The invention belongs to the field of underwater detection, and particularly relates to a deformable sonar array for an underwater mobile platform, which comprises a plurality of linear sonar arrays, a sonar rotating arm, a sonar fixed arm, a bevel gear reversing mechanism, a multi-connecting rod mechanism, a sliding block, a slideway base, a rocker arm, a worm and gear mechanism, a rotating shaft, a motor, a sealed cabin, a base and a flow guide cover, the linear sonar array is fixedly connected with the sonar rotating arms, the sonar rotating arms are connected with the sliding blocks through rotating shafts, the sonar rotating arms are connected through multiple connecting rods, the sliding block on the outermost side is connected with the bevel gear through a rocker arm, and rotation of the whole sonar array is achieved through a worm and gear output shaft. According to the invention, a multi-link mechanism and a bevel gear mechanism are used to realize rotation and angle control of a plurality of sonar rotating arms, and meanwhile, a sonar array can integrally rotate by a required angle. The sonar array has the advantages that the sonar array can be changed into various sonar array types, a circular area array and a parallel line array, the sonar array can rotate integrally, and detection requirements of different working conditions are met.

    本发明属于水下探测领域,具体地说是一种水下移动平台用可变形声呐阵列,包括多条线型声呐阵列、声呐旋转臂、声呐固定臂、锥齿轮换向机构、多连杆机构、滑块、滑道底座、摇臂、蜗轮蜗杆机构、旋转轴、电机、密封舱、底座及导流罩,线型声呐阵列与声呐旋转臂固定连接,声呐旋转臂与滑块之间为转轴连接,声呐旋转臂之间为多连杆连接,最外侧滑块与锥齿轮之间为摇臂连接,蜗轮蜗杆输出轴实现整体声呐阵的旋转。本发明提出使用多连杆机构以及锥齿轮机构实现多条声呐旋转臂旋转及角度控制,同时声呐阵列可以整体旋转所需角度。其优点是声呐阵列可变为多种声呐阵型,圆形面阵,平行线列阵,声呐阵可整体旋转,有利于不同工况的探测需求。
