Title:
MULTI-ROTOR VERTICAL-AXIS WIND TURBINE PROVIDED WITH ROTATABLE SUPPORT FRAME
Document Type and Number:
WIPO Patent Application WO/2024/012210
Kind Code:
A1
Abstract:
The present invention relates to the technical field of offshore wind turbines, and disclosed is a multi-rotor vertical-axis wind turbine provided with a rotatable support frame, comprising wind turbines. The wind turbines are connected to a rotating support device; the rotating support device is connected to a body support device, and can rotate around a connection position between the rotating support device and the body support device; the bottoms of the wind turbines are both connected to a buoy; the buoy of the wind turbines aims to reduce a main bearing load of the rotatable support frame; the body support device comprises a body upright column; the rotating support device comprises a connection plate connected to the wind turbines; two ends of the connection plate are both fixedly connected to flow guide plates; the distance between the axis of the body upright column and the acting center of lateral wind on the flow guide plates at the two ends and wind resistance form aligning torque; or a certain trail distance exists between the axis of the body upright column and the windward side of each wind turbine, and the trail distance and lateral wind resistance form aligning torque. The device is provided with the rotating support device, the aligning torque can drive the wind turbines to achieve automatic wind-facing rotation, the wind utilization rate is increased, and the power generation efficiency is improved.
