Document Type and Number:
WIPO Patent Application WO/2020/230686
Kind Code:
A1
Abstract:
Provided is a floating vertical axis turbine that has a bearing device capable of accommodating a large shaft.　This floating vertical axis turbine comprises: a float (2); a shaft (3) that is connected to the float and is capable of rotation about an axis; blades (6) that are connected to the shaft; and a bearing device (4) that supports the shaft and includes a plurality of bearing units. Preferably, the bearing units each have a support mechanism for receiving the load from waves acting on the shaft. Preferably, the floating vertical axis turbine comprises protrusions (30) protruding radially from the shaft, and the support mechanism comprises: a first roller (13) that supports the outer peripheral surface of the shaft and rotates about an axis parallel to the shaft; and a second roller (15) that supports the blade side of the protrusions and rotates about an axis that intersects the shaft.
