The Windmill with Rotating Sails consists of a block (1) with support bearings (30) along which the reducing gear (3) is running. The generator (2) is also mounted on the block. Fixed to the reducing gear (3) is the rotor (4) with three pairs of vanes (5 and 6), three sails (7) of varying surface, and the fantail (12) which puts the sails (7) into an optimum position to the wind. The sail control mechanism consists of the central differential (9), gear ratio 1:1, which is connected by the shaft (11) to the fantail (12), and by three differential shafts (10) to the sail differentials (8), gear ratio 1:2, which imparts rotation to the sail shaft (17). Each sail (7) has a sail folding mechanism consisting of the gravitational counterweights (22), the slide (21) along which these counterweights are running, the cables (27) spreading the sail holders (19), the centrifugal counterweights (25), the slide (24) along which these counterweights are running, the sail folder (18) on which the sail (7) is wound, the sail holders (19) keeping the sail (7) spread, the upper sail holder slide (20) and the lower sail holder slide (23) along which the sail holder is running, and the small pulleys (26) over which the ropes are running. |
