Title:
WIND-POWERED ELECTRICITY GENERATING DEVICE PROPELLER, AND WIND-POWERED ELECTRICITY GENERATING DEVICE EMPLOYING SAME
Document Type and Number:
WIPO Patent Application WO/2024/101372
Kind Code:
A1
Abstract:
Provided are a wind-powered electricity generating device propeller that rotates efficiently by capturing a large amount of surrounding wind, and a wind-powered electricity generating device. The wind-powered electricity generating device propeller is connected to a body-side surface portion of a shaft portion, and includes blade portions having a shape formed with a taper from a connecting portion side connected to the body-side surface portion toward a tip end portion side of the blade portions, the construction being such that an inclination of a blade surface portion increases in an extension direction of the shaft portion toward the tip end portion side. The wind-powered electricity generating device employing the wind-powered electricity generating device propeller serves as a wind-powered electricity generating system for main power generation or auxiliary power generation on the ocean, and also has the function of a sail by increasing a wind receiving area. Further, high efficiency and durability are provided when employed as a compact wind-powered electricity generating system for onshore wind conditions, and for locations and conditions having a poor wind circulation.
