<p>An impact type wind-driven power generating device is classified into a vertical shaft impact type wind-driven power generating device and a horizontal shaft impact type wind-driven power generating device. The two types of the impact type wind-driven power generating device adopt a power rotor mechanism (10) of a multi-stage impulse blade to utilize the energy of in-coming wind to the maximum extent, thereby improving the utilization of the wind energy. The energy of the in-coming wind is increased due to the height difference and the lateral exhaust of a high-altitude exhaust duct (8), so that the power rotor (10) can generate electric power at a low load even in a sunny windless day. The power generating device can be manufactured into a power generator set with large power and small volume per unit, being convenient to transport, install and maintain, thereby greatly reducing the investment cost of unit power generation amount. The power generating device can receive in-coming wind from any direction without a complicated variable propeller pitch system. A transmission system and a power generator may be arranged on the ground, which is convenient to operate and maintain. The power generating device overcomes the disadvantages of low utilization of the wind energy and the power rotor being difficult to be activated.</p> |
