Title:
WIND TURBINE HAVING FLOW DEFLECTION UNIT
Document Type and Number:
Japanese Patent JP2022125998
Kind Code:
A
Abstract:
To provide a wind turbine which can alleviate such a defect of a conventional technology that torque and motive power generated by a wind force in the vicinity of a hub of a rotating shaft are extremely small.SOLUTION: A wind turbine includes a shaft unit 2 having a tube-shaped hub 22 which is engaged with an inner tube 21 so as to be rotatable around the inner tube while surrounding it, and a plurality of blades 31 connected to the hub 22. The blades 31 include blade units 3 having wind holes 32 formed at roots adjacent to a hub shaft 20, and rotatable with respect to an operation direction 30 by a wind force, and flow deflection units 4 arranged in response to the wind holes 32, and including deflection plates 41 which are connected to the inner tube 21. Since the deflection plates 41 are curved while extending along the operation direction so as to be deflected toward the blades 31 by collecting winds, the blades 31 generate larger torque, and rotation efficiency is improved.SELECTED DRAWING: Figure 4
