Abstract
The invention is a fan structure of an aerogenerator, which is characterized in that the fan comprises a plurality of gate type fan blades. With a tower frame being taken as a revolving center, all fan blades centers are arranged around the tower frame with equidistance and extend outwards radially. Each fan blade includes an external framework and a plurality of vanes arranged horizontally or vertically in the external framework in the form of a louver. A drive periodically controls the vanes to turn synchronously and to form an open or close state. When the fan is used, the drive of each fan blade has an automatic control effect with the automatic detection function of the wind direction. When the fan is in tail wind, each fan blade is periodically driven to switch to the close state and turns by the wind power. When the fan is in head wind, each fan blade switches to the open state to avoid the reverse thrust force of the wind power. The invention can replace the prior axial flow fan structure and improve the running efficiency of the fan.
