Abstract

PROBLEM TO BE SOLVED: To provide a structure capable of efficiently uniformizing sea water intake, in response to changes in swelling sea waves.SOLUTION: A sawtooth-shaped coastline is artificially built, with which the seabed inclination in the cross-section is gradually made gentler from the sea to the land side in a range between 7% and 10%, at the same time laying pipes to a reservoir 17 on the land at inclinations between 3% and 5%. In a planar view, a V-shaped jetty 1 is constructed of which the width gradually becomes narrower from the sea to the land side, having an efficient angle between 30° and 40° that opens from the coastline toward the sea. Swelling sea waves that constantly wash the shore are led into the V-shaped bay and the sea water is stored in the reservoir 17 constructed on the land. The stored sea water is constantly adjusted and discharged, for securing a power source all the time.

Description

The ocean power generation system has been studied in the world, such as temperature difference power generation, tidal current generation power generation, wave height variation generation power generation, but research and development in Japan is thought to be the future, Most of the power generation methods match the changes in wave power that occur in the sea.

Although the tsunami phenomenon in Japan is frequent, especially the heavily damaged Sanriku coast is the V-shaped rias coastline, and the past damage is the largest, the V-shaped jetty was landed based on this lesson learned 100m-300m projecting from the side toward the ocean, guiding ocean swell ocean water waves to the land without resistance, temporarily storing this ocean water, and installing multiple power generators in the course of naturally discharging to the ocean, can always generate electricity The construction structure.

Considering the establishment of the case where there is a wave in the ocean, whether this wave energy can be used to guide it to the land, whether it is sand drifting due to coastal currents associated with the establishment of the facility, or floating objects entering the facility There was a problem in correspondence

Means to solve the problem

  The Rias coast structure is artificially constructed, and the cross-sectional seabed slope is gradually reduced from 7% to 10% in the range from the ocean to the land, while the land is 3% to 5% and piped to the reservoir. Specifically, the V-shaped jetty is gradually narrowed from the ocean, and the efficient angle is 30 ° to 40 ° from the coastline to the ocean, making it a V-shaped jetty structure. It is stored in a reservoir that is led into the V-shaped bay and is installed on the land, and the stored water is constantly adjusted and discharged, and the solution source that can always secure the power source is selected. And measures to change the direction of the coastal flow by directing the discharge water so that sedimentation of drifting sand does not occur.
