WIND POWER HYDRAULIC ROTARY BODY

PURPOSE:To improve efficiency and to reduce production of starting torque, by a method wherein plural collecting blades are situated radially from the surroundings of a vertical rotary shaft so that an angle of elevation is variable within an approximately right angled working range in a plane extending in parallel to a rotary shaft and at right angles with a blade shaft. CONSTITUTION:Plural collecting blades 6 are arranged radially in the surroundings of the upper part of a vertical shaft rotatably supported to a support frame 2, the anchors 1 of which are buried in a ground G, through a radial bearing 3 and a thrust bearing 4 to form a wind power hydraulic rotary body. A generator 7 is mounted to the lower end of the vertical shaft 5 to form a wind air power generating device. The vertical shafts on each of which to mount each blade 6 are rotatably mounted to plural mounting bosses 10 protruded radially from the surroundings of the rotary shaft 5 and at right angle with the vertical shaft 5 by means of a radial bearing 9A and a thrust bearing 9B. The rotation range of each shaft 8 is regulated through a swing pin 11 secured to the shaft 5 and engaged with the groove of a flewing arm 12 secured to the rotary shaft 5.
