WIND TURBINE WITH A SYSTEM OF ORIENTATION AND RESTRICTION OF SYNCHRONOUS ANGULAR VELOCITY OF WIND TURBINES Russian patent published in 2019 - IPC F03D1/00 F03D7/02 

FIELD: power engineering.

SUBSTANCE: invention relates to wind power engineering. Wind unit with a system of orientation and limiting the synchronous angular velocity of a wind turbine is supported with a pinion gear and a vertical axis with a wind turbine head installed on it, device that reacts to the wind direction, made in the form of a curtain, mounted on a hollow vertical axis made in the head of a wind turbine that can be rotated by at least 90°, and located in the wind behind the curtain of the impeller, mounted on the upper end of the vertical, passing through a hollow vertical axis in the head of the wind turbine shaft, having at the lower end a drive gear, kinematically connected with the hub gear, as well as a force opposing mechanism and a wind-sensitive shovel, the bar of which is mechanically connected with the shutter, the shovel's bar is connected with the shutter by means of a hinge that can be rotated by at least 90° in a vertical plane parallel to the direction of the wind, axis of the hinge intersects the axis of the vertical shaft, the first bevel gear meshes with the second bevel gear fixed on the spade rod coaxially with the axis of the hinge, and the force opposing mechanism has points of application of force between the shutter and the rim of the pulley mounted on the spade rod coaxially with the axis of the hinge.

EFFECT: invention is aimed at improving the accuracy of limiting the synchronous angular velocity of a wind turbine.
