Abstract

The present invention relates to an apparatus for converting energy from flowing water (hydraulic turbine). The slidable blades of the apparatus receive the thrust force of flowing water, such that the areas of blades coming into contact with flowing water is maximized. In addition, the blades receive not only the pressure of flowing water, but also the buoyancy of water as the blades are rotated toward the surface of the water so that, by combining these two sources of force, a larger pushing force can be collected. The present invention is suitable of being installed on shores or in rivers, for the purpose of converting energy of flowing water into other kinds of energy, which is to be transmitted in shore for effective use.

  1. 1. An apparatus for converting energy from flowing liquid, the apparatus comprising: a water wheel having an outer rim and an axial center; a wheel axle having a longitudinal axis, the wheel axle attached to the water wheel; a transferring set; a floating body; said water wheel converts energy of a flowing liquid into mechanical energy, which is then converted by said transferring set into transmittable fluid energy or electric energy; wherein the outer rim of said water wheel is shaped as a gear with a plurality of wheel teeth which are symmetrically spaced from the longitudinal axis of the wheel axle; the wheel teeth comprise hollow sections and sliding grooves; half of the wheel teeth each comprises a blade, the blade comprises a first block installed at an end of one side thereof, with a second block installed at another end of another side thereof; and said hollow sections of said wheel teeth permit said blades to sequentially and gravitationally slide therein, during which one of said blocks of one said blade can pass into an oppositely facing one of the sliding grooves of another one of said wheel teeth, with the second block of the sliding one of said blades being stopped at a base circle of the slid into one of said wheel teeth, thus permitting the slid one of said blades to receive thrust force of flowing water without completely rotating about the axis of the wheel axle.
  2. 7. An apparatus for converting energy from flowing liquid, the apparatus comprising: a water wheel having an outer rim and an axial center; a wheel axle having a longitudinal axis, the wheel axle attached to the water wheel; a transferring set; said water wheel converts energy of a flowing liquid into mechanical energy, which is then converted by said transferring set into transmittable fluid energy or electric energy; wherein the outer rim of said water wheel is shaped as a gear with a plurality of wheel teeth which are symmetrically spaced from the longitudinal axis of the wheel axle; the wheel teeth comprise hollow sections and sliding grooves; half of the wheel teeth each comprises a blade, the blade comprises a first block installed at an end of one side thereof, with a second block installed at another end of another side thereof; and said hollow sections of said wheel teeth permit said blades to sequentially and gravitationally slide therein, during which one of said blocks of one said blade can pass into an oppositely facing one of the sliding grooves of another one of said wheel teeth, with the second block of the sliding one of said blades being stopped at a base circle of the slid into one of said wheel teeth, thus permitting the slid one of said blades to receive thrust force of flowing water without completely rotating about the axis of the wheel axle.
