PL407191A1 - Wind turbine propeller - Google Patents

Abstract

A wind turbine propeller is characterized by the fact that on the axis (1) four to eight, preferably seven pairs of bent elements (4) and (5), (6) and (7), (8) and ( 9), (10) and (11), (12) and (13), (14) and (15), (16) and (17) preferably in the form of an arch based on a semi-circle and connected together so that they are shifted relative to each other by 30 ° and in intervals between successive pairs of alternately connected arches are 1/6 of the height (H) of the entire propeller, where the elements (4 - 17) in the form of arches are mounted in the ring (18) or in the fitting with a hole in the center as axis diameter (1). Elements (4 - 17) are successively connected by means of flat plates bent to the curvature of the arches, while the wind turbine propeller is driven by a low-speed current generator mounted directly on the axle (1), and at least one "slide" as a diffuser is attached below the propeller propellers. Preferably, the length of the fitting is 1/6 of the diameter of the elements (4 - 17). It is advantageous if the plates are made of polycarbonate and are fixed successively on the overlap. Preferably, the plates are covered with electricity generating material, especially graphene or perovskite. Wind turbine propeller can work in vertical and horizontal position.
