<P>PROBLEM TO BE SOLVED: To provide a direction control device for a wind receiving blade efficiently receiving wind and saving electric power. <P>SOLUTION: This direction control device for the wind receiving blade 5 includes: a cam 10 having a predetermined irregular curved surface; an anemoscope 11 having a rotating shaft 11a fixed to the cam through the center of the cam and rotatably supported on a hollow revolving shaft 2; a liquid cylinder 7 mounted on a journal rod 3a above each wind receiving blade 5, and having a cylinder rod end attached with a cam roller 7a brought into contact with the periphery of the cam 10 by a spring; and a special hydraulic motor mounted to one of the journal rods above and below the wind receiving blades, and having a motor shaft rotated by a predetermined angle by the amount of liquid moved in and out of the liquid cylinder in association with movement of the cylinder rod 7b. The motor shaft of the special hydraulic motor is made to serve as a wind receiving blade shaft 4a on a side of one journal rod or is directly connected to a wind receiving blade shaft 4b on a side of the one journal rod, and a liquid circuit is provided between the special hydraulic motor and the liquid cylinder moving liquid in and out of the special hydraulic motor. <P>COPYRIGHT: (C)2010,JPO&INPIT |
