Abstract

A wind power plant includes a boom (3), a vertical shaft (4) that supports the boom (3) midway between its ends for oscillatory slewing of the boom in the horizontal plane, a vertically-oriented blade (1, 2) at each end of the boom, wherein each blade can rotate around its vertical axis relative to the boom, coupling devices (7-10, 16, 17, 18, 19, 20; 51-54) that couple the blades (1, 2) together to provide a common rotational movement, wherein the coupling devices are adapted to maintain the blades (1, 2) at mutually opposite attack angles relative to the longitudinal direction of the boom (3), and driving devices (28, 29) that are adapted to force the coupling devices to reverse the attack angle of the blades when the boom (3) is at a selected angle relative to the direction of the wind. The coupling devices include two rotatable rings (10, 19) that are coaxial with the shaft (4). Each of the rings (10, 19) is rotatably coupled to one of the blades (1, 2). The driving device includes a transmission (16, 17, 18, 20; 51-54) between rings (10, 19) that turns the rings uniformly in mutually opposite directions. The transmission is provided with adjustable setting devices (40, 41; 50) that are arranged in a manner to establish a selected attack angle for the blades (1, 2) relative to the boom (3).
