Unmanned underwater vehicle capable of storing multiple sub UUVs and use method thereof

The invention provides an unmanned underwater vehicle capable of storing multiple sub UUVs and a use method of the unmanned underwater vehicle, and belongs to the field of marine equipment and underwater robots. The problems that a traditional UUV is low in operation efficiency and high in cost are solved. The device comprises a parent UUV and a plurality of sub UUVs of different structures, a plurality of storage cabins are evenly distributed on the top of the middle of the parent UUV, two storage baskets are arranged in each storage cabin and connected with the output end of a hydraulic cylinder through rods, the fixed ends of the hydraulic cylinders are installed in shells of the storage cabins, guide rods are installed at release openings of the storage cabins, and the guide rods are connected with the output ends of the storage baskets. And a butt joint mechanism is mounted at the head of the sub UUV and is movably connected with the guide rod. The device is mainly used for ocean exploration. 本发明提出了一种可存储
