Impact type wind-driven power generating device

摘要

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 of a multi-stage impacting 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, so that the power rotor can generate electric power at a low load even in a sunny windless day. The power generating device overcomes the disadvantages of low utilization of the wind energy and the power rotor being difficult to be activated.
