Abstract: According to the present disclosure, at least two fluid inlet/outlet pipes, each of which is provided with a filter, are installed outside a structure to be bent and an end of each of the fluid inlet/outlet pipes is connected to a pressure sensor provided on the structure. Thus, since a fluid in the state in which low-frequency and high-frequency components of the disturbances generated outside the structure are removed therefrom acts on the pressure sensor, the underwater pressure sensing apparatus is capable of measuring fluid pressure in a stable state.

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.

Abstract: This invention relates to amphiphilic hydrogel particles for antifouling paint, which are environmentally friendly and in which anti-corrosion and antifouling effects can be maximized through a single coating process. The amphiphilic hydrogel particles are fabricated by encapsulating conducting polymer particles having anti-corrosion functionality with functional nanoparticles having antifouling functionality and then immobilizing the functional nanoparticles on a hydrogel matrix, whereby the conducting polymer particles contained in the functional nanoparticles are slowly and continuously released or the release rate thereof can be controlled so as to release the corresponding particles in a specific environment, ultimately maintaining long-term functionality. The conducting polymer particles contained in the amphiphilic functional nanoparticles can exhibit anti-corrosion functionality, thus maximizing anti-corrosion and antifouling effects through a single coating process.
