Wind-driven generating apparatus

The invention is a wind power generator, comprising pillar and pillar tensioning ring, where the pillar tensioning ring is connected with tensioning steel rope, a device for wind vane to connect with generator casing is above the tensioning ring, the top end of the pillar is equipped with wind vane beam mount, and a cable is connected from the generator in the generator casing to a generator set control room and the control room is connected with external electric network through cable. And this sail-like wind vane with strong wind catching ability stands up against the wind on the beam mount and falls down reversely, can generate huge torsion force by weak wind, implements anti-vibration auto control, hydraulic auto adjustment, horizontal rotation as horizontal arranged, vertical rotation as horizontal arranged, and horizontal rotation as vertical arranged, and is supported by the pillar, the horizontal grid of steel rope tensions and fixes the wind power generator, and the foundation construction investment is less, the economic property is remarkable, and the wind catching ability is strong, and the invention has features of larger erection height, good stability, large unit capacity, strong anti-damage ability, and wide application range. And the generated power is a clean renewable electric energy.
