WINDWHEEL OF CAROUSEL-SPADE TYPE Russian patent published in 2013 - IPC F03D3/00 

FIELD: power engineering.

SUBSTANCE: windwheel comprises at least two identical modules with fragments of a power column, which carry swings in the form of identical double-end shafts of bearing units rigidly fixed on a fragment of the power column perpendicularly to its axis with displacement relative to each other in a horizontal plane by the angle o and outlet of the ends to opposite sides. At the ends of the swings there are coaxially fixed tabs of a paired blade, being turned relative to each other by 90° around the swing axis, and also an outer frame in the form of a regular polygonal prism common for all modules, which is installed on a support mast. In the centre of the lower and upper bases of the frame there are rigidly fixed support bearing units for installation of the power column common for all modules. The outer frame of the windwheel is divided into fragments with height comparable to the height of the fragment of the module power column. Between fragments of the frame there are intermediate shelves, equipped in the centre with the bearing units and the lower and upper elastic couplings, which connect adjacent fragments of the power column of the modules, and in the corners of the intermediate shelves there are stiff split couplings installed, which connect adjacent fragments of angular stands of the frame.

EFFECT: equal load of a power column along height, compensation of its oscillations and vibrations, simplified assembly when adding or replacing modules.
