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.

Disclosed is an energy-saving bidirectional ship lift by gravity balancing, including: a ship lift body. A first support is provided in a middle of the ship lift body. A second support is provided at a side of the first support. A third support is provided at the other side of the first support. A space between the second support and the first support forms a first shaft. A space between the first support and the third support forms a second shaft. A first ship-carrying chamber and a second ship-carrying chamber are respectively provided in the first shaft and the second shaft to allow two ships to be transported at the same time. An entry water tank and an exit water tank are provided at two sides of each ship-carrying chamber to adjust the weight of the two ship-carrying chambers.

Bidirectional ship lift by gravity balancing

A squid-type marine oil containment device includes a track and four oil containment booms. A robotic arm is provided in an elliptic area formed by the track. Sliders are provided on the track. Ends of oil containment booms slide along the track through sliders. Each oil containment boom includes an oil suction pipe, propellers and a plastic separating layer. A middle of the oil suction pipe forms an oil channel. Booster pumps are spacedly provided inside the oil suction pipe and are respectively connected to a hose. Pairs of propellers are spacedly provided at a lower end of the oil suction pipe. Oil suction holes are provided on the oil suction pipe. The plastic separating layer is provided under the oil suction holes. A counterweight is provided at a bottom of the oil containment boom. The invention further provides a method of containing oil using the device.
