<p>The present invention provides a windmill which is equipped with variable blades, which includes: a support (10) which is combined with a rotary shaft (11) in order to be able to rotate; horizontal rotation plates (20) which are installed to rotate with the rotary shaft (11), are arranged around the rotary shaft (11) in all directions, are lengthily extended in a radius direction, and are arrange to be opposite with the rotary shaft (11) as the center; multiple variable wings (30) which are combined with the upper side of the horizontal rotation plates (20); a connection unit (40) which mutually connects each of horizontal rotation plates (20) which are arranged to be mutually opposite in order to fold or unfold a horizontal rotation plate (20) of one side when unfolding or folding a horizontal rotation plate (20) of the other side; a spacer (50) which is installed in the upper side of the horizontal rotation plates (20) or in the variable wings (30) and prevents a surface contact by forming an acute angle with the horizontal rotation plates (20) when folding the variable wings (30); and a stopper (60) which is installed in the upper side of the horizontal rotation plates (20) or in the variable wings (30) and maintains the variable wings to be vertical to the horizontal rotation plates (20).</p> |
