DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and a method for generating electricity by utilizing the energy of rivers, tidal currents and ocean currents.

[0002]

2. Description of the Related Art In the prior art, there has been no implementation, but as a proposal, Japanese Patent Application Laid-Open No. 07-2596 has been proposed.
There are four.

[0003]

In a conventional marine power generation submarine, the apparatus becomes large in order to obtain a large amount of electric power, the construction cost increases, and the sea area where the submarine can be installed is limited. In addition, there is a problem in that the mooring with an anchor and a mooring line does not provide a sufficient effect even when installed in most of the large meandering ocean currents.

An object of the present invention is to reduce the size of a device, and further to provide a device capable of obtaining a sufficient effect in most of meandering ocean currents and a power generation method using the device.

[0005]

In order to achieve the above object, in the marine power generation submarine of the present invention, a floating body having a rudder fixed to the stern is equal to the height of the velocity head of the marine current by an anchor and a mooring line. The bow is moored at the depth and a frame is fixed to the lower part of the floating body. Inside the frame, a plurality of funnel-shaped conduits are arranged in the same direction at an interval. The intake of the conduit is fixed to the frame facing the bow of the floating body to face the ocean current. Generators equipped with propellers are respectively fixed inside the plurality of conduits. The generator is connected to a submarine cable. The generator is fixed inside the conduit such that the mounted propeller is at the narrowest part of the conduit. The generator is fixed inside a streamlined container, a part of which is perforated and blocked by a membrane. The interior of the container is filled with an oily liquid.

Further, in order to obtain a sufficient effect in a meandering ocean current, the floating body needs to move together with the ocean current,
It is preferable that the floating body is separated from a mooring line and a seafloor cable fixed to the seabed, a rudder is attached to the floating body, a storage battery, a desalination device, and a water electrolysis device are fixed inside the floating body, and a container is mounted outside the floating body. .

[0007] As described above, as a power generation method using an ocean current power generation submarine separated from a mooring line fixed to the sea floor and a submarine cable, hydrogen gas generated inside the submarine is recovered and land-based. There is a method of generating electricity using a fuel cell installed on land.

[0008]

In the marine power generation submarine constructed as described above, when submerging at the depth of the velocity head and mooring on the seabed, the ocean current is taken in from the intake of the conduit fixed at the lower part of the floating body and the speed increases to the maximum speed. When it reaches, the propeller attached to the generator is rotated and sent into the next conduit, and the next conduit is fixed at a distance from the previous conduit so that it can take in ocean currents in the same way Thus, when the ocean current reaches the maximum speed, the propeller attached to the generator is rotated to be sent to the next conduit, and the same operation is repeated inside the connected conduit. The generator is operated by the rotating propeller, generates power, and is transmitted to land by the connected submarine cable.

In the marine power generation submarine separated from the mooring cable fixed to the sea floor and the submarine cable, the conduit connected to the frame fixed to the lower part of the floating body and the inside of the conduit similarly to the marine power generation submarine described above. It electrolyzes fresh water produced by a desalination plant that generates power using a generator fitted with a propeller and runs on electric energy stored in a storage battery inside the floating body.
Hydrogen and oxygen generated by the electrolysis are stored in a container fixed outside the floating body. Also, the propulsive force for the floating body to move or stay at the same place against the ocean current for power generation is obtained by applying a voltage to the generator attached at the end of the frame in the opposite direction to the power generation. Can be

Containers 17 and 18 are fixed to the upper surface of the floating body 1 by frames 24 and 25, and a rudder 28 is mounted on the stern. Other parts are the same as those of the embodiment shown in FIGS.

[0012]

Since the present invention is configured as described above, it has the following effects.

By arranging the funnel-shaped conduits at intervals, the cross section perpendicular to the ocean current on the side where the ocean current of the conduit is taken in can be reduced in proportion to the number of serially connected conduits.

Since the size can be reduced as described above, it is possible to generate power even in a river or a relatively shallow sea.

By removing the mooring line, attaching the rudder, fixing the vessel to the outside, and fixing the desalination device and the electrolysis device inside, it can move together with the meandering ocean current, and the energy of the ocean current can be reduced by hydrogen gas. And stored in an externally fixed container.

Further, by storing the battery in an external container, it can be recovered and generated at a power station using a land-based fuel cell.

By filling the inside of the floating body with a buoyancy material and forming a hole in the lower part of the floating body and closing the hole with a film, the influence of the water pressure is eliminated, and the structure of the floating body does not need to have a pressure-resistant structure.

Since the electrolysis is performed in the sea at the depth of the velocity head, the recovered hydrogen gas does not need to be compressed.
