Abstract
The invention discloses a taper pipe type wind power generation device and aims to provide a wind power generation technology which is simple in structure, high in safety, low in investment, high in yield, low in risk and high in profit. The taper pipe type wind power generation device can be suitable for installation and operation in various environments of water surfaces, mountainous areas, deserts, marshes and lands. According to the funneling effect, the Bernoulli effect, the Venturi effect and the fluid mechanics theory, passive natural wind speed utilization in the conventional wind turbine is changed into active natural wind speed regulation and control. When natural wind blows in through a wind barrel inlet, because the sectional area of a wind barrel is gradually reduced or increased, and the wind cannot be accumulated or is disperse due to air quality, when the wind flows in an accelerated or decelerated mode, the wind speed is gradually increased or reduced and the wind flows into a fan, a impeller of the fan is pushed to drive a flywheel, a gearbox and a generator, and wind energy is converted into electric energy. According to a wind speed control device, the sectional area of the wind barrel inlet is automatically regulated according to the natural wind speed, so that the operating wind speed is regulated and controlled.
