The invention relates to the technical field of underwater equipment recovery, in particular to a water surface position indicating device and a position indicating method for unpowered floating type underwater equipment. The device comprises a tank body, a partition block is fixed to the inner wall of the tank body, the partition block, a first-stage piston and the tank body form a closed upper cabin, the partition block, a second-stage piston and the tank body form a closed lower cabin, and a first-stage piston stop lever is arranged at the top of the tank body; the first-stage piston is arranged in the axial through hole of the spacer block in a sliding manner; the second-stage piston is arranged in a center hole of the first piston in a sliding mode, and the second-stage piston is limited through a limiting mechanism arranged in the first-stage piston. Water surface position indication in the floating process of the underwater equipment is achieved, accurate positioning of the underwater equipment can be achieved, and recovery of the equipment is facilitated.

    本发明涉及水下设备回收技术领域,特别是一种用于无动力上浮式水下设备的水面示位装置及示位方法。装置包括:罐体,其内壁固定有隔块,隔块、第一级活塞与罐体组成密闭的上舱,隔块、第二级活塞与罐体组成密闭的下舱,罐体的顶部设有第一级活塞挡杆;第一级活塞,滑动设置在隔块的轴向通孔内;第二级活塞,滑动设置在第一活塞的中心孔内,通过设置在第一级活塞内的限位机构,对第二级活塞起到限位作用。其实现了水下设备上浮过程中的水面示位,可以实现对水下设备的准确定位,有助于该类设备的回收。
