Title:
RENEWABLE ENERGY-TYPE ELECTRIC POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/042487
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a renewable energy-type electric power generation device capable of appropriately absorbing the relative displacement between a hydraulic pump and a hydraulic motor which are connected by piping. The renewable energy-type electric power generation device comprises: blades; a hub; a rotating shaft connected to the hub; a nacelle in which the rotating shaft is housed; at least one main bearing for supporting, in a rotatable manner, the rotating shaft relative to the nacelle in such a manner that the axial direction of the rotating shaft has a tilt angle relative to the horizontal direction; a hydraulic pump mounted to the rotating shaft and having a discharge opening for discharging pressurized oil obtained by pressurizing hydraulic oil; a high-pressure line through which the pressurized oil flows; at least one hydraulic motor connected to the discharge opening through the high-pressure line and having a suction opening; a motor support section for supporting the hydraulic motor relative to the nacelle; and at least one generator connected to the hydraulic motor. The high-pressure line includes: at least one first piping disposed so as to have a tilt angle relative to the horizontal direction; at least one second piping disposed in a plane perpendicular to the first piping; and at least one first swivel joint section for connecting the first piping and the second piping so as to permit the second piping to pivot within the perpendicular plane relative to the first piping. Either the high-pressure line and/or the motor support section is configured so as to absorb a change in the distance between the discharge opening and the suction opening.
