VERTICAL AXIS MAGNETIC SUSPENSION TIDAL STREAM ENERGY POWER GENERATION APPARATUS AND METHOD COMBINED WITH OFFSHORE HORIZONTAL AXIS WIND TURBINE TOWER

摘要

A vertical axis magnetic suspension tidal stream energy power generation apparatus and method combined with an offshore horizontal axis wind turbine tower, comprising a central unit, magnetic suspension rotor units, and support units; the central unit comprises a horizontal axis wind turbine single-pile tower (3) and a stator winding (4); the single-pile tower (3) is fixed onto the seabed; the stator winding (4) is sleevingly installed on the outer wall of the single-pile tower (3); the magnetic suspension rotor units are suspended around the annular stator winding (4) under the action of the support units; and the support units are closed-loop tracks (10) of T-shaped cross sections, are correspondingly arranged below the magnetic suspension rotor units, and are fixed onto the seabed around the single-pile tower (3). When sea water rises and falls, the sea current pushes blades to rotate, such that permanent magnet poles in the rotor units rotate. At which time, the stator winding (4) installed on the outer wall of the single-pile tower (3) of the wind turbine converts tidal stream kinetic energy into electric energy by cutting and rotating magnetic induction lines; in addition, on the basis of existing offshore wind energy power generation systems, an undersea tidal stream energy power generation method is added, thus effectively improving comprehensive utilization of offshore energy.
