The power generator 2 is connected by means of a power cable 7 laid on the seabed to a land transmission station 8.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep water flow power generation facility which is installed underwater on the sea floor or the bottom of a large river and uses a deep water flow as an energy source.

[0002]

2. Description of the Related Art A tidal power generation facility focusing on tidal power has been proposed (JP-A-5-263413). However, the tidal current is fluctuated, and it is necessary to take measures to equalize the fluctuating energy, and the installation location is also limited in order to obtain the tidal current efficiently.

[0003]

On the other hand, the present invention uses a deep water flow as an energy source which is not affected by natural phenomena or natural disasters or other abnormalities, and which does not hinder the passage of operating ships and the inhabitation of aquatic organisms. Provide a near-futuristic deep water flow power generation facility.

[0004]

In order to achieve the above-mentioned object, the present invention relates to a water flow introduction unit 1 having a substantial weight, which is submerged in the water bottom, and a power generator 2 driven by the water flow of the water flow introduction unit 1. Become. The water flow introduction unit 1 includes an introduction housing 3
A primary passage fence 4 and a secondary passage fence 5 for preventing and eliminating intrusion of foreign matter are provided in front of the vehicle. And the introduction housing 3
Several layers of filters 6 are arranged in the space. The power generator 2 and the onshore power transmission facility 8 are connected by a power cable 7 running along the bottom of the water to form a deep water flow power generator.

[0005] Further, in the above configuration, the present invention is a deep water current generator in which a lid 12 is provided on the upper surfaces of the primary passage fence 4 and the secondary passage fence 5.

Further, in the above-mentioned configuration, at the bottoms on both sides of the primary passage fence 4 and the secondary passage fence 5, expulsion openings 9, 10 for entering foreign substances are provided.
This is a deep water flow power generation device provided with.

[0007] Further, the bottom of the secondary passage fence 5 is a deep water current generator in which a quadrangular pyramid wall 11 is formed.

[0008]

In the case of the seabed as an example, as shown in FIG. 4, a submarine seabed which is not affected by natural phenomena or natural disasters or the like, and which does not hinder the passage of operating ships and the inhabitation of aquatic organisms is selected. I do. In the figure, reference numeral 8 denotes a land power transmission facility, which is connected to the power generator 2 via a power cable 7 running along the sea floor.

Ocean currents (including branch currents and scattered currents) are efficiently prevented from entering large foreign matters while being prevented from directly colliding with the secondary passage fences 5 by the primary passage fences 4, so that the inside of the secondary passage fences 5 is efficiently prevented. In the first passage fence 4 and the second passage fence 5, the intruding foreign matter mixed with the ocean current is removed to the outside from the intruding foreign matter discharge ports 9, 10 at the bottom portions on both sides. In the embodiment in which the bottom of the secondary passage fence 5 forms the quadrangular pyramid wall 11, this elimination is performed more efficiently by the sliding effect of the slope.
Here, the ocean current is stably introduced as a clear stream (FIGS. 1, 2, and 3). Then, the ocean current guided into the introduction housing 3 is further removed of impurities by several layers of filters 6 and then guided to the power generator 2 to drive the turbine (FIGS. 1, 2, and 3), and generated. The generated power is transmitted to a land-based power transmission facility by a cable 7 creeping on the sea floor (FIG. 4).

[0010]

As described above, the present invention provides a stable deep water flow that is not affected by natural phenomena or natural disasters, and that does not hinder the passage of operating ships and the inhabitation of aquatic organisms.
Provide near-future deep-water power generation facilities as a source. For installation, it is necessary to select a water bottom position that is easy to guide the ocean current or the like according to the power generation scale, and an auxiliary device for guiding the ocean current may be necessary. It is only natural to comply with international sea area arrangements. Even in remote places where power plants are not available or where facilities are difficult, such as Amazon's Tomeas relocation area, power can be generated by installing the water bottom according to the scale of each. In the current situation where dependence on nuclear power generation, which poses a great risk on the one hand, is increasing, it is extremely promising as a clean near-future power generation device using natural power.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a water flow introducing section 1 having a substantial weight, which is submerged at the bottom of a water, and a power generator 2 driven by the water flow of the water flow introducing section 1 as a driving source. The water flow introduction unit 1 prevents foreign matter from entering the front of the introduction housing 3.
The primary passage fence 4 and the secondary passage fence 5 to be eliminated are provided. The primary passage fence 4 is constructed by assembling a concrete frame in a bow shape with a horizontal space therebetween, and providing openings 9 for excluding invading foreign matter at the bottoms on both sides.
The secondary passage fence 5 has a square pyramid wall 11 at the bottom and is concreted.
And a jungle gym made of U.S.A., and an exhaust port 10 for invading foreign matter is provided at the bottom of both sides. The introduction housing 3 is made of concrete and is formed in the shape of an aperture toward the power generator 2, and two layers of filters 6 are arranged at the front and rear of the inside thereof. Then, the power cable 7 of the power generation device 2 is connected to a power transmission facility 8 provided on land along the water floor to complete the deep water flow power generation device.
