Description

[Detailed Description of the Invention] (1) Purpose [Field of Industrial Application] The present invention relates to a giant aquarium structure on the ocean, which is capable of efficiently and complexly utilizing ocean resources, energy, and the environment. This provides a new giant aquarium structure on the ocean.

More specifically, by pumping up nutrient-rich deep seawater and creating an artificial ocean current within the giant tank, we are cultivating marine life such as fish and shellfish in the tank, and at the same time draining it from the tank. By using the falling water, we can generate electricity, etc., and create an effect equal to or greater than upwelling currents and ocean currents in the sea area around the falling water, and raise the level of the marine biological breeding base (production base) in the surrounding sea area. We also aim to concentrate and recover useful components such as uranium dissolved in the sea, thermal power generation using low-temperature deep seawater, hydrogen production by electrolysis of seawater, and leisure facilities such as calm water tanks and offshore yacht harbors. In addition to the use of solar cells on the walls of aquariums and other walls to utilize strong sunlight, the use of offshore and underwater urbanization that utilizes structural space, and the use of relay stations for various purposes, as well as The present invention provides a new giant offshore aquarium structure that can make efficient and complex use of ocean resources, energy, and the environment, including power generation.

[Conventional technology]

Marine biological breeding base (production base) in nature
The area is mainly located in upwelling waters, which account for only 0.1% of the total ocean surface area, and upwelling waters produce about 50% of the world's fisheries production. Upwelling water areas are generated by collisions of ocean currents with different temperatures or collisions of ocean currents with the sides of the continental shelf, and continuously supply nutrient-rich deep water several hundred meters deep to the photic layer near the sea surface. In the photic layer, photosynthesis of phytoplankton and algae is promoted, and the food chain produces an abundance of small and even large fish.

Although Japan relies on fisheries resources as one of its main sources of protein, in recent years, due to regulations on the 200-acre economic zone and increasing water pollution in coastal waters, most of the demand for fisheries resources has been diverted from deep-sea fishing and imports. The reality is that fisheries resources depend on fisheries, and it is an important issue to efficiently cultivate and secure fishery resources in coastal waters.

Furthermore, since Japan is not blessed with energy resources, it is also important to effectively recover and utilize the large amounts of energy or potential energy possessed by the oceans.

For this reason, in order to increase and cultivate fishery resources in coastal waters, various projects such as the establishment of fish reefs, aquaculture farms, and coastal conservation are planned and implemented, and based on the marine ranching plan, (a) The main research topics being studied include raising the base of marine biological production by adding salt, (b) generating circulating currents by using waves, introducing seawater into artificial shallow waters on land, and (c) large-scale stocking of cherry salmon and other fish. On the other hand, research is also being conducted to recover and utilize the various types of energy that the ocean possesses in large quantities.

[Problem to be solved]

However, in areas with a depth of several tens of meters or more, it is not possible to economically install fish reefs of an effective scale, so it is not possible to generate upwelling currents or ocean currents. There are problems such as no established theoretical system regarding this. In addition, there is a strong desire to expand offshore aquaculture farms as the inner bays are almost full, but there are technical issues such as the structure, strength, and retention method of offshore facilities, as well as technical issues regarding aquaculture. Although technology for securing seedlings at land-based facilities has been developed,
The technology for maintaining and managing marine life in the sea area after release is immature, and it cannot be said that sufficient results have been achieved.

Furthermore, regarding marine ranching projects, not only are marine area maintenance and management techniques still immature, but a theoretical system sufficient to increase productivity has not yet been established.

Therefore, in order to increase and secure the fishery resources that our country needs in coastal waters, conventional efforts to establish fish reefs, aquaculture farms, coastal conservation projects, and marine ranching plans are based on the efforts of the ocean itself. Compared to upwelling currents and ocean currents, which are ideal fishing grounds, although some results have been achieved, there are limits and it cannot be said to be sufficient.

On the other hand, various technologies for recovering and utilizing the various types of energy that the ocean holds in large quantities have not been sufficiently developed, as they have been studied individually and on a small scale without a convenient foothold for realizing the technologies. It has not yet reached the point where it can demonstrate economic efficiency.

Furthermore, there is a lot of room to utilize the environment, such as the scenery on the ocean.

(2) Configuration [Means for solving the problem] As described in the claims, the present invention is based on a support structure that is based on the seabed in an ocean area with a depth of several tens of meters or more, so that the bottom surface of the tank can be raised 10 meters above the sea level.
