Abstract

The invention relates to plants for wind power conversion into mechanical power which may be used for electric power production.The windmill, according to the first variant, contains a horizontal shaft (1), onto which there is fixed a hub (4), blades (3), fixed onto strokes (2), articulately joined with the hub (4) and the levers (5) with a slotted bush (6), fixed onto the shaft with the possibility of sliding along it, a rotary ring (11), onto which there is mounted into bearing supports (10) the horizontal shaft, joined by a transmission (17) with an electric generator (16), and a tower (14). The strokes (2) are connected to the hub (4) with inclination to the slotted bush (6), between the hub (4) and the slotted bush onto the shaft (1) there is installed a buffer spring or a shock pad (9), and on the other side the slotted bush comes in contact with a pressure spring (7), controlled by a nut (8). The rotary ring (11) is provided with rollers (12) with the possibility of free rotation over a bearing annular surface (13), horizontally fixed onto the top of the tower (14), wherein it is mounted a current collector (15).The windmill, according to the second variant, comprises blades, each with an axle, provided with a needle bearing, an axial bearing and a retainer. The axles of the blades are installed into the hub, and the blades are articulately joined by levers with the slotted bush and are joined between them by ropes, chains or strings.The result consists in increasing the efficiency and in providing the possibility of windmill operation in any weather conditions.
