The invention discloses a low-noise trepanning and sinking device suitable for an underwater unmanned system, and belongs to the technical field of underwater operation appliances. The device comprises a mounting seat, a bearing ring, a wedge-shaped trepanning mechanism, a lever limiting mechanism and the like. The device is installed on the surface of an underwater unmanned system sealing shell,and it can be ensured that the interior of the underwater unmanned system sealing shell is isolated and sealed from the external seawater environment before action; and after the trepanning action isexecuted, a water inlet hole with the diameter of 130 mm (the diameter of the piston body is 130 mm) can be formed in the surface of the underwater unmanned system, and seawater is poured into the unmanned system through the water inlet hole, so the underwater unmanned system sinks and is self-destroyed.
本发明公开了一种适用于水下无人系统的低噪开孔沉没装置,属于水下作业器具技术领域,本发明是由安装座、承重环、楔形开孔机构、杠杆限位机构等组成。本发明安装在水下无人系统密封壳体表面,在动作前可以确保水下无人系统密封壳体内部与外部海水环境隔绝密封;执行开孔动作后,可在水下无人系统表面打开一个直径130mm(活塞体直径130mm)的进水孔,海水通过进水孔灌入无人系统内部,使水下无人系统沉没自毁。
