Counterweight flange is connected with connecting rod one end, and the connecting rod other end is connected with blade, and the blade is equipped with and can freely overturn
Thin bar.
Preferably, the blade side offers through-hole, and described connecting rod one end is mounted on through-hole.
Preferably, described thin bar one end is connected with upper end cover, and the thin bar other end is connected with bottom end cover.
Preferably, the upper end cover and bottom end cover are discoid, the upper end cover identical, position pair with bottom end cover shape
Should, the axis is arranged on upper end cover center.
Preferably, the connecting rod is uniformly arranged on counterweight flange side.
Compared with prior art, the beneficial effects of the utility model are：
It is connect by counterweight flange with connecting rod one end, the connecting rod other end is connect with blade side, and blade opposite side is set
There is the thin bar that can freely overturn, when wind-driven generator remains static, counterweight flange nature due to self gravitation effect
Sink, when wind-driven generator is in rotation status, due to blade and the rotation centrifugal force of connecting rod, pull up counterweight flange
It stretches, when wind-driven generator reaches rated speed, the rotation centrifugal force of blade and connecting rod generates upward component and counterweight method
Blue its own gravity is equal, and when wind-driven generator rotating speed is more than rated speed, the centrifugal force of blade and connecting rod generation is upward
When component is more than counterweight flange own wt, leaf position is intended to the state at upper and lower end face edge, and blade front face area reduces,
Wind-driven generator rotating speed reduces.By the way of variable blade face, for wind-driven generator in the slow-speed of revolution, the front face area on blade face is big,
It is subjected to displacement with the raising blade face of rotating speed, to reduce front face area, the front face area of blade reduces, and rotating speed slowly drops therewith
It is low so that the rotating speed of wind-driven generator maintains normal working condition.
