Abstract

A recovery device for an unmanned underwater vehicle (UUV) includes a first recovery component arranged on an unmanned ship and a second recovery component arranged on the UUV. Two magnets are provided on an end of the first recovery component and an end of the second recovery component which are opposite to each other, respectively. A first cable of the unmanned ship is provided on an end of the first recovery component away from the magnet, and a second cable is provided on an end of the second recovery component away from the magnet. A thruster is provided on a side of the first recovery component. The UUV is recovered using the unmanned ship through the recovery components connected to the cables, which allows the locating and navigation errors to a large extent.
