FIELD: power engineering.SUBSTANCE: wind-driven plant comprises a rotor of vertical rotation installed inside the frame and equipped with blades of alternating section and thickness, bent along the vertical and horizontal line, a flywheel installed on the secondary shaft coaxially with the rotor, and an aggregate block with power take-off mechanisms installed in it. On the inner surface of the rotor blades there are wavy forms with the start of the wave from the external edge of the blade and with an elevation angle from 0°, with transition of the elevation angle in 2/3 of the blade arc up to 60°. On the rounding of the inner part of the blade along its entire length there is an element installed of sickle-shaped section with a clearance. The flywheel is additionally equipped with a system of movable sectors arranged on guides of the flywheel disc and connected by means of rope joints with a counterbalance. The counterbalance is installed concentrically on the secondary shaft with the possibility of vertical movement and is equipped with circular ledges that are in contact with forks fixed hingedly in the aggregate unit and designed to connect different aggregates of power take-off.EFFECT: higher capacity and efficiency of a wind-driven plant with provision of automatic switching of power take-off mechanisms.4 cl, 7 dwg |
