Description

[Technical field]

[0001] The present invention relates to a method for constructing a tidal power generation base equipped with multiple water turbine generators that generate electricity from tidal currents, utilizing the tidal currents generated by the ebb and flow of the tides to serve as an electric fuel supply base for fishing boats. [Background technology]

[0002] Conventional power generation using generators includes thermal power generation, nuclear power generation, nuclear fusion power generation, hydroelectric power generation, geothermal power generation, solar thermal power generation, wind power generation, wave power generation, ocean current power generation, and tidal power generation. With solar thermal power generation and wind power generation being promoted under national guidance, offshore wind power generation is currently attracting attention.

[0003] The current situation in Japan is that construction of offshore wind power generation is being carried out rapidly in some areas suitable for offshore wind power generation.

[0004] Solar thermal power generation is generally carried out using mega-solar power plants that utilize mountains, unused land, and reclaimed land, as well as solar power plants that utilize privately owned land and the roofs of homes.

[0005] However, solar thermal power generation has the problem that it is dependent on the weather and cannot generate electricity at night, and wind power generation and offshore wind power generation also have the problem that they cannot generate electricity unless the wind blows.

[0025] As explained above with reference to the drawings, it is well known that the conversion of automobiles to electric fuel is currently progressing rapidly. Our country is surrounded by a long coastline and has a treasure trove of regularly flowing tidal currents. The present invention provides a method for constructing a tidal power generation base equipped with multiple water turbine generators that generate electricity from tidal currents, which makes it possible to convert fishing boats to electric fuel, as it sees this as an opportunity to save the declining fishermen.

[0027] A self-propelled construction barge 5 equipped with a concrete plant 3 and a construction crane 4 Example 1

[0028] Explaining an embodiment of the present invention with drawings, Fig. 1 shows the tidal power generation base H constructed by the construction method of the present inventor's patent, which is made by joining a structure assembly made of molded members with concrete. A suitable place for tidal power generation 2 is determined, a base for the tidal power generation base H is constructed on the seabed with a self-propelled construction barge 5, the tidal power generation base frame G is constructed on the self-propelled construction barge 5, and concrete 13 made of sea sand collected from the seabed is poured to construct the tidal power generation base H, which is then installed in the designated position for the tidal power plant. Both side walls of the tidal power generation base H are connected to a seawall 11 to construct a tidal current receiving wall 10, and a connecting passage is provided on the tidal current receiving wall 10 to connect the tidal power generation base H and the land 1. This makes the tidal power generation base H a source of income for the fishery cooperative and allows it to be used as an evacuation shelter F in the event of a disaster. Furthermore, it makes it possible to promote the use of electric fuel for fishing boats and to make electric fuel for fishing boats free of charge. On the other hand, fishing associations, which will be revitalized by making electrical fuel for fishing boats free of charge, will be able to concentrate on creating seaweed beds and fishing reefs, and they will also be able to cooperate in disposing of the garbage that washes up along the long coastline. Example 2

[0029] To explain the method of turning seawater into fresh water, heat generated by the generator cooling water circulator L, which cools the multiple generators 7 in the tidal power generation equipment room B, is used to turn seawater into fresh water, which is stored in the fresh water tank at the tidal power generation base H and supplied to the city through the water supply pipe 20 on land 1, making it possible to respond to the interruption of the water infrastructure in the event of a disaster. On the other hand, the deterioration of Japan's water infrastructure is serious and repairs are urgently needed, so tidal power generation base H plays a huge role in Japan and the income from selling water is important income for the declining fishing industry. Example 3

[0030] As for the multipurpose use of tidal power generation base H, by connecting both side walls on the tidal inlet side of tidal power generation base H to seawall 11, the tidal pools can be used as a fishing pond and an outdoor restaurant set up at tidal power generation base H can be used to eat fish from fish tank I. The income gained from this will be important for the declining fishing industry. [Industrial Applicability]

[0031] Japan is surrounded by a long coastline, and there are huge fishing associations where fishermen who protect the long coastline gather and shipyards that build boats, but the vitality is being lost due to a sharp decline in fish catches. In order to bring vitality back to the coastline, the method of constructing a tidal current power generation base equipped with multiple water turbine generators that generate electricity from tidal currents, which is related to the present invention, will utilize the inexhaustible tidal current energy that flows along the coastline day and night regardless of the weather. This will promote the use of electric fuel for fishing boats and make the electric fuel for fishing boats free of charge. On the other hand, the fishing associations, which will be revitalized by making the electric fuel for fishing boats free of charge, will be able to concentrate on creating seaweed beds and fishing reefs. Furthermore, the fishing associations will cooperate in processing the drifting garbage that washes ashore along the long coastline. [Brief description of the drawings]
