Linear darrieus vertical-axis wind power generation apparatus capable of large-scale manufacture

Abstract

The present invention relates to a straight-bladed Darrieus vertical-axis wind turbine. A cylindrical inner rotating shaft is vertically supported by upper and lower bearings, and a frustum-shaped outer stationary shaft surrounding a lower portion of the rotating shaft is eccentrically and inclinedly arranged to define an enlarged machine-room space in a lower region of the turbine. A power take-off gear and a brake disc are disposed at the lower portion of the rotating shaft to enable efficient resistance to bending loads and to facilitate large-scale implementation. One or more brake discs having a brake-disc wall are fixed to the lower portion of the inner rotating shaft and are clamped by at least one brake caliper, and a braking/output control device including a water supply device is provided to effectively control excessive power output.
