#$%^&*AU2017390078B220190718.pdf#####ABSTRACT The present application provides a wind turbine pitch device and a wind turbine, wherein the pitch device may comprise a disk driving structure, a crank, a connecting rod, a slider, a 5 guide rail, and a driving motor. The disk driving structure may be fixedly mounted on the blade and perpendicular to an axis of the pitch bearing; one end of the crank may be fixedly connected to the disk driving structure; one end of the connecting rod may be hinged to the other end of the crank; the slider may be hinged to the other end of the connecting rod; the guide rail may be arranged on the hub and sliding fit with the slider; and the driving motor 10 may drive the slider to move along the guide rail. The present application provides a wind turbine pitch device and a wind turbine which may implement a pitching of the wind turbine and have a simple structure, while it may not be required to drive a pitch system in a hydraulic manner. There may be no leakage and replacement of hydraulic oil, which may reduce a maintenance cost of the wind turbine, and oil-resistant electrical equipment and 15 cables may not be required, thus the adaptability of the wind turbine may be better.
