A passive time-delay passive positioning device suitable for an underwater environment comprises a cabin shell, an end cover, a cabin cover, a cabin cover fixing ring, a cabin cover sealing ring and a buoyancy tank positioning assembly. The cabin shell is of a cylindrical structure, the two ends of the cabin shell are closed through end covers, and two cabin openings are formed in the cabin shell and used for installing the cabin cover. The hatch cover fixing ring is fixedly installed at the hatch position and sealed through the hatch cover sealing ring, and the hatch cover is fixed to the hatch cover fixing ring through hydrosol. Two buoyancy tank positioning assemblies are mounted in an inner cabin of the cabin shell, and the two buoyancy tank positioning assemblies are placed at an angle of 180 degrees; when the passive time-delay passive positioning device enters water, a water-soluble fixing belt and a water-soluble vinylon yarn which play a fixing role in the buoyancy box positioning assembly lose efficacy, a buoyancy box in the buoyancy box positioning assembly ejects a hatch cover away from a hatch opening under the action of elastic power and then goes out of the hatch, a thin cable is pulled by positive buoyancy to float to the water surface, and then the passive time-delay passive positioning device is driven to move out of the hatch. And the underwater equipment is positioned through traction of the thin cable. The problems that a traditional positioning device is large in error and needs to be operated by professionals are solved.

    一种适用于水下环境的无源延时被动定位装置,包括:包括舱壳、端盖、舱盖、舱盖固定圈、舱盖密封圈和浮箱定位组件。舱壳为圆筒状结构,两端通过端盖封闭,舱壳上开有两个舱口,用于安装舱盖;舱盖固定圈固定安装在舱口位置,且通过舱盖密封圈密封,舱盖通过水溶胶和舱盖固定圈固定;舱壳的内舱中安装有两个浮箱定位组件,两个浮箱定位组件之间呈180度摆放;当无源延时被动定位装置入水后,浮箱定位组件中起固定作用的水溶性固定带和水溶性维纶纱线失效,浮箱定位组件中的浮箱在弹性动力作用下将舱盖顶离舱口后出舱,利用正浮力牵引细缆绳上浮至水面,通过细缆绳牵引进行水下设备定位。本发明解决了传统定位装置误差大、需要专业人员操作的问题。
