Title:
HORIZONTAL-AXIS BOTH-END-SUPPORTED WIND-SHIELDING WIND TURBINE
Document Type and Number:
WIPO Patent Application WO/2019/021631
Kind Code:
A1
Abstract:
[Problem] To provide a wind turbine of which the aerofoils can be increased in size and which can efficiently generate approximately 100-30,000 kw of power with one machine. [Solution] A horizontal-axis double-end-supported wind-shielding windmill has been discovered to be many times more efficient than other wind-cup turbines or Savonius turbines because the aerofoils can be made stronger due to being supported at both ends, the aerofoils can be increased in size, and obstructing wind is shielded, to a greater extent than in various other wind turbines. This type of wind turbine can effectively utilize tailwind and headwind, and the aerofoils are formed into flat-surface shapes rather than the conventional curved shapes. Furthermore, wind-shielding walls are provided to the entire area below a horizontal rotary shaft, the entire area above the horizontal rotary shaft is opened so as to be a wind-receiving area, tailwind and quartering tailwind is received by the front surfaces of the aerofoils to cause the wind turbine to rotate forward, and headwind and quartering headwind is received by the rear surfaces of the aerofoils to cause the wind turbine to rotate in reverse. Making the aerofoils sturdier with both-ended support yields the effect that a power-generating apparatus having a wider range of 100-30,000 kw in one machine can be constructed, and power can be supplied at far lower cost in terms of electric expenses per kilowatt than with existing technology.
