Abstract
A windmill converting wind forces into rotational energy that can be used to drive a generator or other apparatus requiring rotational energy to work. The windmill includes panels for capturing the wind arranged around a vertically rotating shaft. The panels are able to move from a vertical position when receiving the force of the wind to a horizontal position when rotated to the upwind side of the rotation, thus minimizing their aerodynamic resistance. The panels can also be moved toward or away from the vertical shaft and the area of the panels can be changed so as to maintain a constant speed of rotation of the vertical shaft.
Claims12
A windmill, comprising:
- a vertical rotating shaft supported by bearings on a vertical supporting post,
- horizontal supporting members attached to the vertical rotating shaft,
- panels attached at their upper edge to the horizontal supporting members,
- stoppers or frames disposed so as to maintain the panels in a vertical position when the panels receive wind force on the front of the panel,
- wherein the attachment of the panels to the horizontal supporting members is by a hinge that allows the panels to raise to a nearly horizontal position or to a horizontal position when the panels receive wind force on tile back of the panel and;
- wherein the horizontal supporting members are threaded to form a screw and are attached to a servo motor by which the panels can be moved toward or away from the vertical rotating shaft.
A windmill, comprising:
- a vertical rotating shaft supported by bearings on a vertical supporting post,
- horizontal supporting members attached to the vertical rotating shaft,
- panels attached at their upper edge to the horizontal supporting members,
- means for maintaining the panels in a vertical position when the panels receive wind force on the front of the panel,
- wherein the panels are attached to the horizontal supporting members by means that allow the panels to raise to an approximately horizontal position or to a horizontal position when the panels receive wind force on the back of the panel and;
- means for moving the position of the panel along the horizontal supporting member relative to the vertical shaft so as to maintain the rotation rate of the vertical shaft constant upon variation in the wind speed.
