COMPOUND COMPACT WIND TURBINE GENERATOR OF BELL-SHAPED CROSSFLOW DARRIEUS TYPE

摘要

PROBLEM TO BE SOLVED: To provide a compound compact wind turbine generator of a bell-shaped crossflow Darrieus type, starting rotation even in a weak wind region, efficiently converting wind force energy into turning force, having high power generation efficiency, maintaining mechanical strength and reducing the weight.;SOLUTION: There is provided the compound compact wind turbine generator 1 of the bell-shaped crossflow Darrieus type, which includes: a bell-shaped crossflow wind turbine 2 provided rotatably around a vertical axis C; a Darrieus wind turbine 3 arranged rotatably around the same axis as the wind turbine 2; a generator 4 for the crossflow wind turbine, arranged above the crossflow wind turbine 2 and driven by the wind turbine 2; a generator 5 for the Darrieus wind turbine, arranged below the Darrieus wind turbine 3 and driven by the wind turbine 3; a protective frame 6 covering and protecting the outer peripheries in the vertical direction of the crossflow wind turbine 2 and the Darrieus wind turbine 3 for a predetermined width while spacing at a predetermined interval and fixing the generator 4 for the crossflow wind turbine and the generator 5 for the Darrieus wind turbine at upper and lower parts, respectively.;COPYRIGHT: (C)2012,JPO&INPIT
