CAROUSEL-TYPE WIND WHEEL MODULE Russian patent published in 2011 - IPC F03D3/00 

FIELD: power industry.

SUBSTANCE: carousel-type windwheel module includes fragment of power column with vertical rotation axis, on which at least one bearing assembly with horizontal arrangement of double-extended shaft is rigidly fixed. Ends of the above shaft protrude to diametrically opposite sides of fragment of power column and carry blades for interaction with wind and which are turned relative to each other through angle a around axis of their carrying shaft. On end part of each blade, which faces the module rotation axis, sector plate is rigidly fixed with threaded hole for screwing of blade on the shaft end extension and that sector plate is connected to retainer plate installed on its square groove, and additional ballast weight can be installed by means of bolts attaching the sector plate to retainer plank. Power column fragment is made in the form of two-sided threaded coupling on which one bearing assembly is rigidly fixed, and communication elements between bearing assemblies are made in the form of branch pipes of various length with thread on both ends for screwing of double-faced couplings with bearing assemblies into common power column of windwheel. Plug is installed on branch pipe end adjacent to upper threaded coupling relative to it, and lubricant supply hole is made in branch pipe wall closer to the plug.

EFFECT: reducing specific metal consumption of windwheel at improving operating efficiency.
