FIELD: wind-electric power engineering; driving of various actuators at heavily fluctuating wind. SUBSTANCE: multistage windmill with its windwheels and frame mounted on common shaft has its windwheels coupled with shaft by means of overrunning clutch. In this case, windwheel located in region of slow wind velocity creating torque on windwheel providing for lower angular velocity of windwheel relative to shaft angular velocity disengages shaft by means of overrunning clutch. In the action, windwheel does not prevent rotation of windwheels located in region of higher wind velocities thereby improving conditions for utilizing wind forces. Overrunning clutch provides for disengaging separate windwheels and using them and units located in the region of their rotation. EFFECT: improved utilization of wind forces at heavily fluctuating wind; simplified maintenance of multistage windmill. |
