WIND POWER PLANT Russian patent published in 2018 - IPC F03D5/04 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind power installation contains vertically oriented and fixed on the supporting surface racks, with which the rails of the upper and lower lying track of the closed contour are connected at the height from the supporting surface. Some carriages are successively connected to each other and each of them is connected with rollers to the rail of the upper track by means of rollers, additional carriages are also sequentially connected to each other and are located below the level of the rails of the upper track. Vertically oriented two blades are connected to the frame of each carriage of the upper rail, one of which is mounted above the rail of this track and the second under the rail, while this second blade is hinged to the corresponding additional carriage of the lower rail. On the frame of the first carriage a generator is mounted with a wheel on the shaft, put in contact with the surface of the rail. Turning mechanism for changing the position of an upstream blade in relation to the wind flow vector is a flap in the form of a plate or wing of an airfoil, which through the tail beams is connected with the blade located above the rails of the upper mounted rail track and is equipped with a flap angle change actuator. Blade above the upper rail is pivotally connected to the carriage to ensure its rotation around the vertical axis, and the underside of the blade is rigidly connected with the axis of rotation of the blade above the upstream rail, with the specified axis of rotation of the blades placed on the frame, which is pivotally connected to the runner block of the carriage.

EFFECT: invention aims to reduce the dynamic loads and increase reliability.
