ORTHOGONAL WIND MOTOR WITH INCLINED FOLDED BLADES Russian patent published in 2017 - IPC F03D7/06 F03D3/06 

FIELD: power industry.

SUBSTANCE: invention relates to wind power engineering. The orthogonal wind motor with the inclined folded blades comprises a wind wheel installed on housing of the planetary reduction gear, located in hollow PTO shaft with installed on it power tooth-wheel and for contact current collector, a central braked axle with installed at bottom end reverse worm drive, and at top end there is a weathercock assembly of blades self-orientation to wind, coupling and pushers to open the kinematic links of the folded blades, rollers for planes rotation of the folded blades at right angle to central axis of rotation, power take-off device and support mast. The hollow PTO shaft assembly, bottom part of central braked axle with reverse worm drive, and PTO device in form of a generator assembly are locate d in independent fixed closed housing beyond the support mast. Above the reverse worm drive on the braked central axle additionally six-contact current collector is installed, and drive of the lifting platform is installed outside the carrying hollow shaft. The pushers opening the kinematic links of the folded blades are made in form of arc-like plates and secured on rotating frames, the rotating rollers are installed on external edges of the lifting platform against blade axles, and on top end of the braked central axle under the weathercock assembly additionally a spring-loaded rotating anti-storm flag with pressed contact switch of circuit of wind wheel spontaneous stop and blades folding during storm.

EFFECT: invention increases the generated power and anti-storm protection.
