The invention provides a one-way pulling lock catch device for an unmanned underwater vehicle, and relates to the technical field of unmanned underwater vehicles, the one-way pulling lock catch device comprises a lock catch connecting rod assembly, a variable radius one-way ratchet mechanism and a cable underwater operation device lock disc; the lock catch connecting rod assembly is connected with the ratchet mandrel through a spring. The tail end of the lock catch connecting rod is provided with a buckle structure. The radius-variable one-way ratchet mechanism comprises a radius-variable one-way ratchet, a ratchet mandrel, a driving pawl, a driving pawl spring and a driving sliding block; the locking disc of the cable underwater operation device is composed of a locking disc body and a traction cable, the locking disc body is a part of the cable underwater operation device, and the purpose that only the cable is pulled to control releasing and locking of a lock catch mechanism is achieved. The overall structure is simple, electric components are not needed, the reliability is high in the severe underwater environment, the cost is low, and energy, controllers and underwater cable resources are saved for the underwater vehicle.
本发明提供一种无人潜航器用单向拉动锁扣装置,涉及无人潜航器技术领域,包括锁扣连杆组件、变半径单向式棘轮机构和带缆水下作业装置锁盘;锁扣连杆组件通过弹簧与棘轮心轴连接,锁扣连杆末端有卡扣结构;变半径单向式棘轮机构包括变半径单向式棘轮、棘轮心轴、驱动棘爪、驱动棘爪弹簧和主动滑块构成;带缆水下作业装置锁盘由锁盘、牵引线缆构成,且锁盘为带缆水下作业设备的一部分,实现仅拉动线缆控制锁扣机构的释放和锁止,该机构的优势在于仅利用带缆水下作业设备线缆的收放动作控制设备与航行器的连接和释放,整体结构简单,无需电动部件,在水下恶劣环境中可靠性高、成本低廉,为水下航行器节约了能源和控制器以及水下线缆资源。
