PURPOSE: A lift-force power generation apparatus by using a sliding unit and vortex induced vibration is provided to induce a vertical vibromotive force by generating an angle of flow attack on a lifting surface by the rotational vibration of a cylinder which is linked to the font and the rear side of the lifting surface by a vortex induced force in which fluid flow to act on the cylinder, thereby generating useful energy. CONSTITUTION: A lift force power generation apparatus by using a sliding unit and vortex induced vibration includes a vortex-induced vibration cylinder(10), a supporting shaft(20), a hydrofoil(30), a drive unit(100), and a guide frame(110). The vortex-induced vibration cylinder is vertically vibrated by a vortex which is generated according to the separation of the vortex from the surface which is caused by the flow speed of the sea or/and a river. The supporting shaft is delivered with the vertical vibration of the vortex-induced vibration cylinder. The hydrofoil performs a translational rotation by lifting force which is generated by the vibration of the vortex-induced vibration cylinder and the flow speed, and amplifies the vibration. The drive unit is connected to both sides of the hydrofoil through a rotary shaft(31), driven vertically by the vibration of the hydrofoil, and formed with multiple through holes(101) on one end side, where the through holes are composed of permanent magnets(102). The translation spring has one side which is connected to the translation link to elastically support the translation link. The supporting frame is supported by being hinge-connected to the other side of the translation link and by being linked with the other side of a supporting spring. The power plant is connected to a hinge shaft of the translation link which is hinge-connected to the supporting frame, and converts kinetic energy of the vortex vibration, which is delivered through the translation link, into electrical energy. The guide frame has guide bars(111) which are installed respectively in each through hole of the drive unit to guide the vertical operation of the drive unit, and a coil unit(112) which is installed on the outer circumferential surface of the guide bar in which the repetitive vertical motion of the drive unit generates electricity. |
