A wind driven generator having buffer devices (3); a base (1) is provided with a generator (11) thereon driven by a rotating shaft (12); a plurality of blades (21) of a windmill (2) are disposed on the periphery of the rotating shaft (12); support rods (23) are respectively connected between each blade (21) and the rotating shaft (12); buffer devices (3) having a seating part (31) and a retractable rod (32) are respectively connected between the rotating shaft (12) of the base (1) and each blade (21) of the windmill (2); one end of the retractable rod (32) is provided with a piston head (321) located inside the seating part (31), and the other end opposite the piston head (321) is pivotally connected to the inner side surface of the blade (21); a connecting rod (33) pivotally connected to the rotating shaft (12) is disposed on one side of the seating part (31) opposite the retractable rod (32); when a strong wind blows the windmill (2), the blades (21) thereof pull the retractable rod (32) to cause displacement of the piston head (321), and regulated oil (311) or an elastic element (312) inside the seating part (31) combine to generate damping effect supplemented by the reduction in blade rotation speed when the blades (21) deflect, thus avoiding structural damage or destruction caused by high rotation speed of the blades (21), solving the problem of bumping noise, and improving the overall function and effect. |
