WIND ELECTRIC POWER CONVERTER (VERSIONS) Russian patent published in 2020 - IPC F03D1/00 F03D1/02 F03D7/04 

FIELD: power engineering.

SUBSTANCE: group of inventions relates to a wind electric power converter. Proposed converter comprises electric generator including stator 1 and armature 2, blade propeller 7 and wind vane 9. Blades 8 are installed on hub 11 with possibility of changing inclination angle of profile of blades 8 to plane of rotation of propeller 7. Propeller 7 is made with automatic control mechanism of aerodynamic resistance of propeller 7 to head of air flow and is installed by hub 11 on shaft 12 of armature 2 by spline or key movable connection, spring-loaded conical compression spring 14 between disc 15 and end fairing 13 fixed on shaft 12. Each blade 8 is installed movably on axis 10, fixedly fixed in hub 11, and is equipped with turning lever 16 located at an angle to the plane of disc 15 and pressed to it by a free end by means of spiral spring 17 fixed on axis 10, with possibility of end of lever 16 sliding on disc 15, which changes angle of inclination of profile of blades 8 to plane of rotation due to shift of hub 11 towards disc 15 and back to fairing 13 as head of airflow of head wind to screw 7.

EFFECT: invention is aimed at improving operating reliability due to stabilization of wind pressure on rotating blade propeller.
