<p>PURPOSE:To reduce rotary reaction force preventing rotary motion of a windmill, by synchronizing rotary motion of two paddle-type windmills, rotating in an opposite direction to each other, with mutually different phases and moving wind receiving blades of the two windmills in a mutually entering state. CONSTITUTION:The winds blowing to directions A, C tend to rotate a windmill 1 counter clockwise and a windmill 2 clockwise. Then the wind to a direction B presses a wind receiving blade 22 to act to the direction of rotary reaction preventing clockwise rotation of the windill 2, here a wind receiving blade 12 comes to rotate behind the wind received blade 22, then the wind to the direction B is not directly blown to the wind receiving blade 12. In this way, if rotary motion is continued, the wind received blade 12 shields the wind to the direction B, and a wind receiving blade 23 rotates in a state of no wind. Accordingly, reaction force to the direction preventing the rotary motion is halved, and integrated efficiency of the windmill can be doubled.</p> |
