POWER SYSTEM OF THREE-SHAFT WINDMILL

FIELD: wind-power engineering; power generation and supply through voltage regulator. SUBSTANCE: power system has supporting structure that mounts head turning about its vertical axis and carrying moving windwheels with shaped radial blades; energy using equipment kinematically coupled with one of windwheels; windwheel speed limiter provided with head-mounted vertical stabilizer; as well as rudder mounted on exit edge of vertical stabilizer and trimmer, on exit edge of rudder, both aerodynamically balanced out and installed by means of external hinged brackets; trimmer is coupled through link with control blade brought out beyond turbulent wind stream and secured with its plane to face wind on end of external bracket hinged on turning head for deflection in horizontal plane and spring-loaded to oppose wind; system has three moving wheels made in the form of propellers whose shaft axes are horizontal; shaft axis of intermediate propeller is unidirectional with wind flow and those of extreme propellers are arranged symmetrically on either side along directions of wind flow intersecting at one point behind it; blades of each propeller are fixed on front ends of shafts so that plane of revolution of intermediate-propeller blades overlaps those of blades of each extreme propeller at certain angle and all of them are intersecting; blades of extreme propellers are facing intermediate propeller; they are arranged in-between its blades, their airfoils are adjusted for opposing rotation at same speed by means of bevel gears provided on rear ends of shafts; energy using equipment, primarily electric generator, is kinematically joined with intermediate-propeller shaft, say, through coupling. Propeller shafts and energy using equipment are mounted above upper plane of turning head and secured thereon by means of external taut struts; gears and blades may be made of caprolactam. EFFECT: improved power capacity and service life of system. 4 cl, 2 dwg
