Abstract: The present invention relates to a hybrid wind power tower including: a DSCT structure part having an inner steel tube and an outer steel tube that concentrically stand on a foundation, wherein a space between the inner steel tube and the outer steel tube is filled with concrete; and a steel structure part provided on the DSCT structure part. The hybrid wind power tower having a steel tower and a DSCT tower combined is configured in such a manner that a plastic hinge that is required to bear huge loads is provided with the DSCT tower structure having high strength, and the economical steel tower structure is provided on the plastic hinge, thereby maximizing safety and cost efficiency of a wind power tower.

Abstract: The present relates to a suction foundation in which is penetrated into the seabed by a vacuum pressure of a suction pump, thereby providing a desired foundation support force. The suction foundation includes a hollow caisson having an opening at a lower end thereof, where the suction pump is connected to the hollow caisson and the suction pump allows the hollow caisson to penetrate into the seabed while discharging a fluid in the hollow caisson to an outside thereof by using the vacuum pressure of the suction pump, a lower skirt provided along a circumference of the opening of the hollow caisson and formed into a wave shape having a series of teeth, and having wedge-shaped cross-sections, and a stiffener increasing rigidity of the lower skirt by increasing thickness of a predetermined portion of the lower skirt.

Abstract: Disclosed herein is a tidal current power generator having an underwater connecting structure, which is capable of ensuring the promptness, correctness and safety of an electrical coupling without support by a diver. The tidal current power generator includes: a nacelle in which a turbine rotor and a power generator are installed; and a tower which is coupled to or decoupled from the nacelle. A plug connector is included in the tower. The nacelle includes a hollow tube forming a passage in which the plug connector is inserted and being filled with a nonconductive filler, a socket connector coupled to the inside of the hollow tube and connected to the power generator, and a check valve which is installed in the passage of the hollow tube and prevents the filler from escaping from the hollow tube when the plug connector is not inserted in the hollow tube.

Abstract: A multiple oscillating water pumping device includes: a wing member disposed in fluid to generate a lifting force using the flow energy of the fluid; a rotation device to reciprocally rotate the wing member to periodically change the direction of the lifting force acting on the wing member; an arm is rotatably coupled to the wing member, the arm being reciprocally rotated about a pivot shaft by the lifting force acting on the wing member; and a cylinder where fluid enters and exits according to the internal pressure that is periodically increased and decreased by the reciprocating motion of a piston that is connected with the arm through a connecting rod. The multiple oscillating water pumping device is configured to minimize the supply of a power source required for operation and to minimize the loss of head when pumped water flows toward a reservoir along a conduit.
