Patent ID: 8344538

Claim:
A wind-powered device for producing electrical energy, including: a generating set suitable to generate electrical energy by conversion of mechanical energy into electrical energy, a wind-powered assembly suitable to capture the energy from the wind and to convert it into mechanical energy, a transmission arranged between said wind-powered assembly and said generating set, said transmission being suitable to transmit mechanical energy produced by said wind-powered assembly to said generating set, said wind-powered assembly including at least two wind turbines, each wind turbine having a shaft, said shafts of said at least two wind turbines being non-coaxial and coupled to said transmission and arranged in such a way that said wind turbines are able to present an equivalent surface area to the wind that is greater than the windward surface area of each of the wind turbines, said transmission having at least one input shaft coupled to said wind-powered assembly, said at least one input shaft being driven in rotation by said at least two non-coaxial shafts of said at least two wind turbines pertaining to said wind-powered assembly, at least one driven pinion mounted on said at least one input shaft of said transmission, and at least two driving pinions respectively mounted on said at least two non-coaxial shafts of two wind turbines, said at least two driving pinions having different numbers of teeth from each other, and being engaged with a same driven pinion, so that said two wind turbines are able to drive said input shaft in rotation.
