Abstract

PROBLEM TO BE SOLVED: To solve problems of accumulation of drift sand due to the fact that geological features of a coast of an ocean area called open sea are frequently found as a sandy feature, and of a counter flow from the final effluent passage of water receiving facilities from a land side at the time of occurrence of tsunami.SOLUTION: This invention provides means for preventing accumulation of drift sand by changing artificially tidal current at coast to off-shore by determining a position of the final effluent passage from water receiving facilities in view of a tidal flowing direction at a coast and guiding the direction of final effluent to sea in parallel with a direction near the final effluent passage at a "w" shaped caisson type bulkhead; means for preventing accumulation of drift sand within the "w" shaped caisson bulkhead bay by making the extremity end of the final effluent into a discharging water of a duct line to the offshore and extending it up to the extremity end of the "w" shaped caisson type bulkhead; and means for arranging a tide wall bulkhead of coast and a back-flow preventive gate as a countermeasure for preventing back-flow from the final effluent at the time of occurrence of tsunami.

Description

  Ocean power generation methods include temperature difference power generation, tidal current power generation, wave power generation, etc., but each has its own special characteristics, but it is considered that tidal current power generation methods can always supply without much change. It is considered that the wave power generation method is being studied, but the change is always large and the efficiency is not good, so there is a large amount of energy even in the place selection and no wind condition. If ocean swell is used, a stable power source is always secured. Developed the swell power generation system

  Because it is difficult to ensure that the efficiency is always constant, it is difficult to construct a rias coast from the cause of the height of the tsunami on the rias coast seen in the Great East Japan Earthquake, and to guide the seawater to the land and use it as a power source. I thought about using swell with large energy as a power source.

The wave power generation facility structure was considered as an average wave of 1 m or more offshore offshore, but it was difficult to secure the wave height on average, and there was a problem in profitability.

Means to solve the problem

Profitability is ensured by ensuring that the average wave height can be used with safe swell even in windless conditions, and by artificially providing multiple w-shaped bays with a minimum of Roman letters instead of a single jetty. As a means to solve the problem, the installation location is a means to guide the swell, which is a power generation source with greater energy to be installed on the coast of Sakai and Yukai Castle name for each bay

Embodiment of the Invention

The safety against the swell of the Roma-shaped jetty is based on the highest wave height on the land side of the Great East Japan Earthquake, considering the destructive power of the swell, and ensuring safety at p = 3wh. The wave height is between the narrow part and the shallow part of the bay. Embodiment which grasps point, decides w bay extension, and secures wave height of land side receiving mouth

Effect of the invention

As a result of the experiment, it is possible to ensure that the swell is higher than the wave power.

Claims (6)

By constructing a caisson-type revetment in the shape of a roman letter from the land coast to the ocean offshore, the swell of the ocean is guided into the w-shaped caisson Yaipu revetment bay, and narrowed by a certain width toward the land side, increasing the swell wave height, Moreover, by reducing the water depth from the ocean to the land at a constant gradient, the seawater is guided to the water receiving facility on the land side by further increasing the swell wave height, and the seawater is used as a power source to generate the drop power generation equipment. This is a marine swell-based power generation facility structure patent that can efficiently generate clean energy by installing multiple rotary power generation equipment in the waterway. Roman character w-shaped caisson type revetment with a ridged shape, installed on a rubble mound, with a structure that provides a minimum of 10m for the dog running width, the mound stacking gradient is 1.5-2.0 gradient, Roman character w-type caisson type The seabed in the revetment bay is constructed with 10 tons / unit or more of stone-cobbled, and the upper part is constructed with concrete stone. The land-side tip of the Roman-shaped w-shaped caisson-type revetment is a concrete frame, the tip exit width is 5m, the bottom gradient is 30 degrees from the sea side, and the seawater inlet width of the concrete frame is 20m, increasing the swell height. Construction structure with a long frame length to the land side Seawater that overflows from the 5m outlet of the concrete frame tip is used as a power generation source for the drop power generator and led to the waterway, and the waterway is equipped with multiple rotary power generators to improve power generation efficiency. Is the facility structure to be released to the ocean Planar layout of the water receiving facility is a facility structure that prevents sand drift in the w-type caisson type revetment bay by discharging it to the upstream side of the coastal flow with respect to the discharge. It is said that the construction conformity of the power generation facility structure using ocean swell is on the coast that touches the Kashima Pass, Sagami Pass, Enshu Pass, Kumano Pass, Harima Pass, Bingo Pass, Pass, Iyo Pass, Shuobo Pass Pass, Hyuga Pass, Amakusa Pass, Genkai Pass, etc. Facility structure to construct w-shaped caisson type revetment or cell revetment type continuously in a sawtooth shape
