Title:
CIRCULATION TYPE WIND TUNNEL WINDMILL POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/071260
Kind Code:
A1
Abstract:
A circulation type wind tunnel windmill power generation device capable of performing windmill power generation by installing a generator matching a load consuming an energy calculated by using the rotational speed of a windmill obtained by dividing two times the wind velocity of an air blower by the circumference of the windmills and the torque thereof obtained by multiplying the radius of the windmills by four times the blowing out force of the air blower. A plurality of windmill storage boxes (1), (2), and (3) incorporating the plurality of windmills (5) and forming wind tunnels on both sides of the windmills are formed in a circulation type wind tunnel by passing a windmill shaft (6) therethrough to integrate the windmill boxes with each other for each windmill at the same position in each box, installing generators (13) and (14) at both ends of the windmill shaft, and joining wind tunnels in each windmill storage box through ventilating tubes (16), (17), (18), and (19) in which air blowers (22) are installed. Thus, the amount of power generation can be increased in proportion to the number of the boxes which increases the number of the windmill storage boxes, and the wind power generation as a regenerative energy can be sustained by an artificial wind generated by the device of mechanical structure without requiring the use of a generated power after the air blowers are started.
