DEVICE FOR CONTROLLING ROTATION OF BLADES OF TWO WIND WHEELS Russian patent published in 1995 - IPC

FIELD: wind power engineering. SUBSTANCE: movable bushing is provided with a ridge under which a plate is mounted for permitting movement in the guide grooves made in the base. Two axles are mounted from the top of the bushing for left and right blocks. The boss with threaded openings for the lead screw is made from bellow. The screw is set in bearings of the base. The axis of the shaft is parallel to the axis of the lead screw, the ridge and both axes being arranged in the same plane. The left and right blocks are in contact with the ridge side through a flexible member. The unit at the rods is in contact with rods secured to the ends of the beam through flexible members. One of the flexible members rounds the blocks from the back side. One end of the rod is secured to the front part of the rod, and the other end to the rear side of the ridge after tension. The rear side of the ridge is spaced from the left or right rod at a distance which exceeds the half outer diameter of the wind wheel. EFFECT: improved accuracy of controlling. 6 dwg
