<p>PURPOSE: A power generating device using a water mill is provided to prevent the circulation of a generator, since both ends of a rotary support shaft are supported on a guide groove of a vertical post. CONSTITUTION: A power generating device using a water mill comprises a floating housing(10), a water mill blade(11), a rotary support shaft(20), a rotary shaft support unit, a rack portion, a drive gear, and a generator. The floating housing has a cylindrical shape. The water mill blade is installed along the outer circumference of the floating housing. The rotary support shaft is installed through the inside of the floating housing to support the rotation of the floating housing. The rotary shaft support unit supports both ends(21) of the rotary support shaft. The rack portion is formed on the inner circumference of the floating housing. The drive gear engages with the rack portion. The rotational motive power is transmitted to the generator through the drive shaft of the drive gear. The generator is installed in the rotary support shaft. The rotary support shaft has the cylindrical shape. The both ends of the rotary support shaft have the cross section of a square shape.</p> |
