Horizontal axis wind generator

摘要

A horizontal axis wind generator comprises a wind turbine with a plurality of blades, which extend between a first portion at the turbine rotational axis and a second end portion, an electric power generator coupled with the wind turbine and having a rotor adapted to be set in rotation around a rotor rotational axis, motion transmission members for transmitting the rotation energy of the wind turbine to the rotor. The motion transmission members comprise a frame associated with the second end portions of the blades and the rotor is operatively coupled with the frame with an aerodynamic profile both for the inlet and for the outlet of the air flow.

1. A horizontal axis wind generator comprising:
a stationary structure adapted to be fixed to the ground; a wind turbine having a shaft adapted to rotate around a horizontal turbine rotational axis, said wind turbine comprising a plurality of blades, each blade extending along a direction substantially perpendicular to said turbine rotational axis between a first portion at the turbine rotational axis and a second end portion, said wind turbine having a front portion and a rear portion, said plurality of blades being arranged at said rear portion; an electric power generator coupled with the wind turbine so as to convert the rotation energy of the wind turbine into electric power, said electric power generator having a rotor adapted to be put in rotation around a rotor rotational axis; and motion transmission members for transmitting the rotation energy of the wind turbine to said rotor, said motion transmission members comprising a frame associated with the second end portions of said blades and rotating jointly with the blades, said frame comprising an annular structure extending along the perimeter defined by the second end portions of the blades, said annular structure having a plurality of fixing portions, each fixing portion being fixed to a respective second end portion of a blade so as to make the annular element rotate jointly with the blades, wherein said electric power generator is a single electric power generator having a single rotor, and said single rotor is operatively coupled with said frame, said wind turbine, said electric power generator and said motion transmission members are coupled in rotation with said stationary structure, said annular structure has inlet and outlet wing profiles adapted to convey the flow of air incident on the wind turbine towards the blades, each wing profile extends between said front portion and said rear portion, said annular structure has a conveying portion shaped so as to channel in inlet the flow of air incident on the wind turbine and in outlet the flow of air expelled by the blades of the wind turbine, and said conveying portion is arranged at said front portion and is shaped as a truncated cone that is tapered from the front portion towards the blades.
