Paddle rotating device of variable-pitch wind driven generator

The invention discloses a paddle rotating device of a variable-pitch wind driven generator. The paddle rotating device comprises a flow guide cover and three paddles, a mounting groove is formed in the flow guide cover, a driving mechanism is arranged in the mounting groove, three sets of transmission mechanisms meshed with the driving mechanism are arranged in the mounting groove in an annular array mode, three sets of rotating mechanisms meshed with the transmission mechanisms opposite to the three sets of rotating mechanisms are arranged on the flow guide cover, the three blades are connected with the rotating mechanisms opposite to the three blades through connecting mechanisms, first annular sliding grooves are formed in the side walls of the three sets of connecting mechanisms, and a plurality of fixing mechanisms extending into the first annular sliding grooves opposite to the flow guide cover are arranged on the flow guide cover. The paddle rotating device is reasonable in structural design, stable ro
