<p>PURPOSE: A self-powered device using air current is provided to prevent the flow of air current from decreasing by minimizing the area of wind power rotating units while aligning the wind power rotating units in a transverse direction. CONSTITUTION: A self-powered device using air current comprises a fan(100), a duct(200), wind power rotating units(300), and a power generator(400). The fan is operated by a drive motor(110). Duct is connected to blower. The duct is connected to the fan, and offers a path for discharging or supplying air. The wind power rotating units are installed inside the duct, and rotated according to the flow of the air. The power generator generates electricity by receiving rotational power from the wind power rotating units, and supplies the electricity to the drive motor.</p> |
