초록

A windmill includes a freely rotatable revolution shaft, a plurality of pairs of pivotal support rods provided at the revolution shaft, and wind receiving blades respectively and rotatably set between the pivotal support rods with wind receiving blade shafts. The windmill is applied to the driving of a lifting pump, a generator and the like by employing revolution driving force. An anemometer/anemoscope measures wind velocity and direction. A servo motor controls the direction of the wind receiving blades based on the detected velocity and direction. Var...
