A vertical-axis maglev tidal current energy generation device and method combined with an offshore horizontal-axis wind turbine tower

Abstract

The present invention provides a vertical axis magnetic levitation tidal current energy generating device and method combined with offshore horizontal axis wind turbine towers, including a central unit, a magnetic levitation rotor unit and a support unit, wherein the central unit includes a horizontal axis wind turbine unit Pile tower and stator winding, the single pile tower is fixed on the seabed, the stator winding is sleeved on the outer wall of the single pile tower; the magnetic levitation rotor unit is suspended around the annular stator winding under the action of the support unit The supporting unit is a closed-loop track with a T-shaped cross section, which is correspondingly arranged under the magnetic levitation rotor unit, and is fixed on the seabed around the monopile tower. When the sea tide rises and falls, the sea current pushes the blades to rotate, which makes the poles of the permanent magnets in the rotor unit rotate. At this time, the stator winding installed on the outer wall of the single pile tower of the wind turbine converts the kinetic energy of the tidal current into electrical energy by cutting the rotating magnetic induction lines. This invention increases the tidal current energy under the sea to generate electricity on the basis of the existing offshore wind power generation system. The method effectively improves the comprehensive utilization rate of offshore energy.

Description

technical field [0001] The invention belongs to the technical field of offshore tidal current power generation, and relates to a vertical axis magnetic levitation tidal current power generation device and method combined with an offshore horizontal axis wind turbine tower. Background technique [0002] The tidal current mainly refers to the regular sea current generated along with the tidal phenomenon, and its main current changes its size and direction twice a day. Tidal current power generation is in shallow seas, straits, bays or estuaries, directly using the impact of high-speed water caused by rising and ebbing tides to drive a Tidal Stream Generator (TSG) with impellers to convert the kinetic energy of the tidal current into electrical energy. Compared with traditional barrage-type tidal power generation, tidal current power generation avoids the high-cost construction of blocking sea dams, has flexible development scale, and has little impact on the natural ecology of...
