1, only need on sea bed, make a call to a cover pile foundation, a pylon can be installed offshore wind farm and ocean current power generation system simultaneously, has reduced construction cost.

2, wind energy and ocean current can import same generator, have improved the generated output of separate unit generator.

3, only need a generator be installed above the water surface of pylon, not need it is done complicated water-proofing treating, only need a cover accumulation of energy or peak adjusting device directly to be connected in the output terminal of generator, compare have now two kinds independently power generation system simplified supplementary equipment.

4, because turbine blade is provided with the expanding duct that is with sleeve outward, sleeve and expanding duct carry out two-stage speedup water conservancy diversion to current, thereby have quickened the flow velocity of the current of expanding duct throat, have improved the generated output that is installed in the turbine blade here.
