The invention relates to the technical field of underwater operation tools, in particular to a self-unfolding and folding device. The invention discloses an underwater self-unfolding and folding device for an acoustic array. According to the technical scheme, a piston cabin is connected with a sealed cabin in a sealed mode; one end of the piston rod is positioned in the piston cabin, and the other end is connected with the movable support; the fixed support is fixed on the piston cabin body; folding rods in the folding rod group are respectively connected with the fixed support and the movable support; the hydrophone array is mounted on a second folding rod and a fourth folding rod in the folding rod group; in an initial state, air pressure in the sealed cabin is balanced with atmospheric pressure, the piston rod is located at the topmost end of the piston cabin under the action of the spring, and the folding rod set is in a completely folded state; and after entering water, the piston rod moves downwards along the piston cabin body under the action of water pressure and drives the folding rod group to extend and unfold outwards. According to the invention, a water pressure and spring driving form is adopted, no complex mechanism or component is contained, the device can be automatically unfolded and folded, the reliability is high, the cost is low, and the device can be repeatedly used.

    本发明涉及水下作业器具技术领域,特别涉及一种自展开与折叠装置。一种声学基阵水下自展开与折叠装置,其技术方案是:活塞舱体与密封舱体密封连接;活塞杆的一端位于活塞舱体,另一端与活动支座连接;固定支座固定在活塞舱体上;折叠杆组中的折叠杆分别与固定支座、活动支座连接;水听器阵安装在折叠杆组中的第二折叠杆和第四折叠杆上;初始状态,密封舱体内气压与大气压平衡,活塞杆在弹簧作用下处于活塞舱体的最顶端,此时折叠杆组处于完全折叠状态;入水后,活塞杆在水压作用下,沿活塞舱体向下运动,并带动折叠杆组向外伸展展开。本发明采用水压和弹簧驱动的形式,不含复杂机构及元器件,可自主展开和折叠,可靠性高,成本低廉,并且可重复使用。
