Vertical axis wind turbine-bi-directional wave energy device-tidal current energy device integrated structure based on tension leg platform

Abstract

The invention provides a vertical axis wind turbine-bi-directional wave energy device-tidal current energy device integrated structure based on a tension leg platform and belongs to the field of oceanenergy utilization. The integrated structure comprises a vertical axis wind turbine, a bi-directional wave energy device, a bi-directional hydraulic power generating system located in the bi-directional wave energy device, a tower-truss structure, a tension leg platform structure, a horizontal tidal current energy power generating device and a matched power transmitting system. The bi-directionalwave energy device can simultaneously utilize movement perpendicular to and parallel to the tower-truss structure to drive a hydraulic transmission system to generate power, and the utilizing efficiency of wave energy is effectively improved; and through an arranged horizontal relatively-moved wave energy hydraulic power generating system, the horizontal acting load of a wave energy floating bodyon the tower-truss structure is effectively reduced, and the construction cost of the tower-truss structure is reduced accordingly. Longitudinal shaking and transverse shaking of the floating-type platform can be effectively controlled through a tension leg structure, good operating of a top draught fan is facilitated, and the huge tower truss bending moment load caused by inertial motion of a top engine room which is high in weight is controlled.
