Impact type wind-driven power generating device

An impact type wind-driven power generating device, comprising:

• a wind turbine, a central shaft of the wind turbine is vertically disposed;
• an exhaust duct that is disposed coaxially with the wind turbine, the lower end of the exhaust duct is communicated with an upper shell of the wind turbine, an exhaust outlet on the upper end of the exhaust duct is disposed in the horizontal direction;
• a power rotor that is disposed coaxially with the wind turbine and is located at the bottom of the wind turbine;
• blades that are disposed inside the wind turbine and are installed at the periphery of the central shaft of the wind turbine;
• an exhaust-air collection chamber that is coaxial with the wind turbine, the exhaust-air collection chamber is formed by a surrounding arrangement of the blades and is communicated with the exhaust duct;
• a transmission shaft that is disposed coaxially with the wind turbine, the upper end of the transmission shaft is connected to a central shaft of the power rotor, and the lower end of the transmission shaft is connected to a power generating device;
• an air inlet is disposed on a lateral wall of the wind turbine;
• a wind collector disposed at the air inlet that includes a wind channel tapered from the air inlet towards the central shaft of the wind turbine;
• guiding ribbed-plates provided on the wind channel and arranged at intervals in a longitudinal direction, the guiding ribbed-plates combing the airflow entering into the wind turbine;
• an airflow accelerating nozzle disposed at the tail end of the wind channel, the airflow accelerating nozzle is close to the blades for filtering sand, dust, and rainwater carried by the in-coming wind and for accelerating the in-coming wind;
• and
• a revolving shaft, which is provided with an adjusting gear assembly, that rotatably connects the airflow accelerating nozzle to the upper shell of the wind turbine, the adjusting gear assembly can drive the airflow accelerating nozzle to rotate around the revolving shaft so as to control an air supply rate from the airflow accelerating nozzle into the wind turbine.
