This invention relates to a wave energy generator for a coastal protection system. The wave energy generator includes a base structure arranged in a body of water and configured to protect a portion of a coastline against incoming waves. The base structure has a foundation located on a floor of the body of water and a wall extending from the foundation to a point above a highest predicted height of the waves. At least one duct is associated with the base structure for receiving an oscillating water column from the body of water. The oscillating water column oscillates in response to wave action of the incoming waves and the duct forms part of an energy extraction system for capturing energy from the incoming waves.

Coastal protection and wave energy generation system

In recent years, offshore wind power generation structures, offshore tidal power generation structures, and offshore wave power generation structures have been provided as individual structures and have been independently installed, operated, and managed. Although the above described structures are provided as superior individual power generation structures, since wind, tidal energy, and waves, which are power sources for generating energy, are not always regular or stable, the power sources may be complementary and interact with each other in terms of power generation efficiency and stability. To this end, the present invention relates to a single structure in which at least two individual power generation structures from among an offshore wind power generation structure (1), an offshore wave power generation structure (2), and an offshore tidal power generation structure (3) are combined. Representative drawing: FIG. 1.

Combined offshore power generation structure

A generator using wave power and wind power of the present invention has eco-friendly structure comprising: a lower supporting structure (20) moving up and down from the sea bottom to the surface of the sea by being fixed to a coast sea bottom ground by a number of mono pile anchors (10); an upper supporting structure (40) floated on the surface of the sea by buoyance as being connected to the top of the lower supporting structure through a number of supporting bolts (30); a wave power generation unit (50) generating electric energy by rotary force repetitively obtained by descending to the sea bottom directionally by wave power and gravity by being installed in the lower supporting structure and then ascending to the surface of the sea by buoyance after direction change; a wind power generation unit (60) generating electric energy by wind by being installed on the upper surface of the upper supporting structure in the form of tower; and a capacitor (70) storing the electric energy generated in the wave power generation unit and the wind power generation unit as being installed on the upper surface of the upper supporting structure. The generator can generate the electric energy stably and continuously, and also can be transported and installed in the coast sea bottom by means of small scale, and can minimize maintenance and management costs.

The present invention relates to a semipermeable breakwater of a combined power generation facility which has a support reaction wall, a wave power generator, and a wind power generator which can be installed in a structure of a semipermeable breakwater by using an in-site post of a prefabricated caisson for a prefabricated panel and a support prefabricated panel to be installed in an in-site post of a lower footing. To achieve this, according to the present invention, a lower footing is installed on a sea-bed. A support post is in contact with a base rock be being drilled. A prefabricated panel is stacked in a post reinforcement support for the inside thereof to be filled with broken stone and earth and sand to increase a loading object. A support prefabricated panel is stacked in a front surface between a plurality of in-site posts wherein the prefabricated panel is stacked. A reinforcing bar, concrete, and cap beam are installed between each post and a support reaction wall to be integrated, and an upper plate is installed on the cap beam. A sunlight collector plate is installed in a remaining space of the upper plate, and a tower of a wind power generator is installed by being interlocked with a post support in a rear surface of a raised floor, thereby being installed to sufficiently handle a rotational force and a lift force of the wind power generator. Moreover, a power transmission pipe is installed in the wind power generator.
