Abstract: A device for sea water desalination and power generation, including: a tidal current turbine, a coupling, a revolving shaft, a booster pump, and a body. The body includes a chamber, a divider, and an end cover. The divider and the end cover are in fixed connection to the body, and the divider divides the chamber into a closed pumping chamber and a closed desalination and power generation chamber. The booster pump is disposed in the pumping chamber and is driven by the revolving shaft. The tidal current turbine is connected to the revolving shaft via the coupling. The desalination and power generation chamber includes a seawater pretreatment device, a seawater desalinating unit including an unsteady reverse osmosis membrane, a flow battery, and a controller. The booster pump is connected to the seawater pretreatment device via an inlet tube, and is connected to the seawater desalinating unit via an outlet tube.
