CAROUSEL-TYPE WINDWHEEL MODULE Russian patent published in 2009 - IPC F03D3/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to wind power engineering and can be used in high power wind-driven power plants. The carousel-type windwheel module contains a fragment of a power column with a vertical axis of rotation, on which are rigidly fixed at least three bearing units spaced out on the height with horizontal arrangement of shafts and their displacement from each other in the horizontal plane at an angle of 60°, for example. At the ends of the shafts, blades are rigidly fixed, each of which in a pair lies diametrically opposite the sides of the fragment of the power column. The shafts of the bearing units are solid and have identical ends, which come out on both sides of the fragment of the power column, on which there are threaded shanks for screwing on blades and square grooves, in which retainer plates are put at 90° from each other with a pair of openings for fastening bolts. On the frontal part of each blade, facing the axis of rotation of the module, a sector plate is rigidly fixed with a similar pair of openings, made on the radial line of the sector, and a threaded bushing at its top. Each pair of blades fixed on the common shaft forms a rigid structure with a common rolling axis in the bearing unit, turning of the blades about it relative each other by 90° and location of the geometric centre and centre of gravity of each of them below their common rolling axis, as well as attachment of an additional balance weight on the same fastening bolts.

EFFECT: invention provides for stabilisation of the number of rotations of the module for any fluctuation of wind speed.
