A wind driven generator comprises a support, a horizontal rotating shaft is arranged in the middle of the support, and blades are evenly distributed in the circumferential direction of the horizontal rotating shaft and connected with the horizontal rotating shaft through radial supporting rods. The shaft end of the horizontal rotating shaft is connected with a hydraulic pump which is connected with a hydraulic motor, and the hydraulic motor is connected with a power generator. The support is located on a circular rail through rolling wheels arranged at the lower end of the support, a support rotating motor is arranged on the lower portion of the support, and a motor shaft of the support rotating motor is provided with a driving wheel matched with the circular rail. According to the technical scheme, wind gathering plates are arranged at the upper end and the lower end of the support correspondingly, and the blades are wing-type-section blades arranged in parallel with the horizontal rotating shaft and provided with wind resisting grooves. The wind driven generator is simple in structure, low in manufacturing cost and convenient to mount and repair; a wind wheel is small in size and low in gravity center; a transmission system is simple, durability is good, and work reliability is high.
