Abstract: A wind-hydro power generation system and its power generation method which use both wind power and hydraulic power. Increasing the size of a hydraulic turbine for the hydraulic power generation may result in the decreased rotation power of the hydraulic turbine caused by the resistance of the wind when blades on the hydraulic turbine come out of the water. A blade rotation system on the blades of the hydraulic turbine is provided so that the blades may rotate according to the direction of the wind. As a result, wind resistance is not effected to the rotation of the hydraulic turbine even when the blades on the hydraulic turbine are out of water, but enhances the rotation power of the hydraulic turbine, which enables the use of wind power and hydraulic power at the same time.

Increasing the size of a hydraulic turbine for the hydraulic power generation may result in the decreased rotation power of the hydraulic turbine caused by the resistance of the wind when blades on the hydraulic turbine come out of the water. The present invention has a blade rotation system on the blades of the hydraulic turbine so that the blades may rotate according to the direction of the wind. As a result, wind resistance is not effected to the rotation of the hydraulic turbine even when the blades on the hydraulic turbine are out of water, but enhances the rotation power of the hydraulic turbine, which enables the use of wind power and hydraulic power at the same time.

Abstract: Disclosed is a power generating system utilizing hydraulic force, and, more particularly, is a hydraulic power generating system, in which a plurality of water receiving plates are mounted on an elongated looped rail floating on the surface of water, thereby allowing the looped rail to be rotated by hydraulic force. To solve a conventional problem in that each of the water receiving plates on the looped rail receives a deteriorated hydraulic force due to the presence of a preceding water receiving plate and results in low use efficiency of hydraulic force, the looped rail is obliquely installed with respect to a water flow direction by an angle of 10 to 45 degrees, and the water receiving plates are installed at a right angle to the water flow direction.

Abstract: A hydraulic power generating system is disclosed. The hydraulic power generating system includes a looped rail, a plurality of pulleys moving along the looped rail, a plurality of water receiving plates, each being installed to each of the pulleys, side plates which are hingedly coupled to left and right side portions of each of the water receiving plates by hinge shafts, and spread adjusting devices which make the side plates spread against a direction of water flow. Accordingly, since the spread direction of the side plates hingedly coupled to both side portions of the water receiving plate can be changed forward and backward according to the direction of water flow so as to receive a larger amount of water, efficiency in generating power using water energy increases.

Abstract: A hydraulic power generating system designed to minimize equipment costs by simplifying the configuration thereof, to maximize efficiency of power generation by reducing loss in hydraulic power, and to allow economical and convenient maintenance of the system. The system comprises a power generator, a buoy floating the power generator on the surface of the water, and a fixing apparatus restricting movement of the buoy and the power generator. The power generator comprises a looped rail, a plurality of pulleys moving along the rail, a coupler to join the plurality of pulleys, a plurality of wings, each being installed to each of the pulleys to move the pulley by absorbing flow energy of water, and a generator installed in the rail to generate electricity after receiving kinetic energy of the pulleys through power transmission gears.

Abstract: Disclosed is a wind power generating system. The system comprises moving bodies connected one with another by connectors and repeatedly circulated on a rail of an endless track; sail devices rotatably mounted to the moving bodies and exposed to wind, each sail device having a sail and a mast and including a rotating mechanism for rotating the mast; geared members affixed to one sides of the moving bodies; a generator having a gear which is meshed with the geared members and thereby rotated to allow the generator to generate electricity; direction changing devices located at both turnaround portions of the rail; and sail direction adjusting devices each for adjusting a direction of the sail in conformity with a direction of wind stream.
