Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water flow type power generation device that generates power by using a flow of water generated by waves generated on a coast or the like.

[0002]

2. Description of the Related Art Conventionally, various types of power generation devices utilizing natural phenomena such as hydraulic power and wave power have been provided in various types, but a hydroelectric power generation device which uses a large amount of water stored in a dam to turn a turbine is known. The mainstream.

[0003]

However, these power generating devices using natural fluids (water) have hardly been put into practical use except for so-called hydroelectric power generation, which is a method of making a dam and utilizing a head of water, and has not yet been tested. You are in a stage state. That is, there are many mountains,
In Japan, which has a lot of rainfall, it has been considered that the most reasonable method is to build a dam to store a large amount of water, use the head of the stored water to turn a large turbine, and supply a large amount of power. Nuclear power generation, which was replaced by natural destruction caused by dams and floods, was replaced by nuclear power, which was far from safe and reasonable, with the danger of radioactivity.
SUMMARY OF THE INVENTION An object of the present invention is to provide a water flow type power generation device that uses a flow of a wave rushing to the shore and rotates a turbine to obtain electricity via a generator.

[0004]

In order to achieve the above-mentioned object, the present invention provides an inflow chamber 1 having a box-shaped container-like apparatus main body A provided with a partition plate 3 for dividing the apparatus main body A into right and left parts. And a discharge chamber 5, a cut B is provided in the front side plate of the inflow chamber 1, a plurality of backflow prevention plates 2 are provided in the cut B so as to be openable and closable inward, and a partition plate 3 is provided in the inflow chamber 1.
A window C is provided in a front side plate of the discharge chamber 5 which is adjacently provided with a through hole, and an inflow stop plate 6 is provided in the window C so as to be openable and closable outward. A generator 10 is installed in the output chamber 5 facing the flow hole 4, a turbine 8 is provided at the position of the flow hole at the shaft tip of the generator 10, and a lid 7 is provided above the discharge chamber 5. It is a thing.

[0005]

Embodiments of the present invention will be described below. When the present invention is actually used, the front surface of the water flow type power generation device provided with the cut B and the window C is installed so as to face the direction in which the waves are coming. In the case of installation, it is installed at a position where waves (seawater) rushing sufficiently enter the inflow chamber 1 and when the waves are drawn, all the seawater in the apparatus goes out of the apparatus. With such a setting, the waves that rush in push in the backflow stop plate 2 that opens only inward from the cut B provided on the front surface of the inflow chamber 1 and enter the discharge chamber 5.
The seawater enters only the flowing water chamber 1 and becomes full because the inflow stop plate 6 on the front surface of the is opened only in the outward direction. The seawater in the inflow chamber 1 flows into the discharge chamber 5 from the flow hole 4 of the partition plate 3 because the backflow stop plate 2 in front of the inflow chamber 1 closes at the same time as the wave is drawn.
At this time, since the inflow stop plate 6 in front of the discharge chamber 5 opens, the seawater in the room is discharged therefrom. When the seawater from the inflow chamber 1 flows into the discharge chamber 5 through the circulation hole 4, the turbine 8 rotates. And a generator 10 via a shaft 9 directly connected to the turbine 8.
Activate When the next wave comes in, the inflow stop plate 6 in front of the discharge chamber 5 is pushed by the wave and is closed, and the backflow stop plate 2 in front of the inflow chamber 1 opens to allow seawater to flow in, and at the same time the wave is drawn The backflow stop plate 2 is closed, and the seawater flows from the circulation hole 4 to the discharge chamber 5.
And the turbine 8 is rotated to operate the generator to generate electricity as described above. By repeating such a process, power generation is performed semi-permanently as long as waves are generated.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a partially cutaway perspective view of the present invention, FIG. 2 is a view showing a series of operating states of the present invention viewed from a plane, FIG. 3 is a longitudinal sectional view near a window, and FIG. FIG. 5 and FIG. 5 are views showing an application example in which a plurality of water flow type power generation devices of the present invention are juxtaposed. In the drawings, reference symbol A denotes the device main body, B denotes a cutout, and C denotes a window.

Reference numeral 1 denotes an inflow chamber formed by partitioning the inside of a box-shaped apparatus main body A with a partition plate 3;
Is provided with a notch B in the front surface of.

[0008] Reference numeral 2 denotes a backflow stop plate 2 which is provided horizontally openably and closably inside the cut B. The backflow stop plate 2 is provided so as to open inward, and when a wave comes in. Seawater flows into the inflow chamber 1 without resistance, and is closed by the water pressure in the inflow chamber 1 at the same time as the wave is drawn, so that the water does not flow backward.

Reference numeral 4 denotes a circulation hole provided in the intermediate bottom of the partition plate 3, and the seawater entering the inflow chamber 1 flows into the discharge chamber 5 through the circulation hole 4, and the inflowing seawater is formed by waves. The pull-in plate 6 provided in the window C is opened as soon as it is pulled, and is discharged to the outside from here.

Since the discharge chamber 5 is provided with a lid 7 at the upper part, all the seawater flowing from the inflow chamber 1 is pushed out of the inflow stop plate 6 through the window C and discharged to the outside.

The inflow stop plate 6 is provided outside the window C of the discharge chamber 5 and is opened only to the outside.
The seawater that has flowed into the discharge chamber 5 through the circulation hole 4 is drawn by waves and is pushed out of the inflow stop plate 6 to be discharged.

Reference numeral 7 denotes a cover provided on the upper part of the discharge chamber 5. By providing the cover 7, seawater does not enter the discharge chamber 5 except through the flow hole 4 from the inflow chamber 1. . Reference numeral 8 denotes a turbine. The turbine 8 is attached to the tip of a rotating shaft 9 of a generator 10 provided in the discharge chamber 5 and is provided in a flow hole 4 provided in the center bottom of the partition plate 3. Mounted to match.

Reference numeral 9 denotes a shaft of a power generator 10. A turbine 8 provided at the tip of the generator 10 passes from the inflow chamber 1 through the circulation hole 4 to the discharge chamber 5.
It rotates by the flow of seawater flowing into the inside, and electricity is generated from the generator 10 by the rotation of the shaft 9 directly connected. As shown in FIG. 5, it is also possible to connect a plurality of the present invention, and a large amount of electric power can be produced by doing so.

Even when a high wave comes in, since the upper part of the inflow chamber 1 is open, seawater exceeding the capacity of the inflow chamber 1 flows out of the room, and the discharge chamber 5 is closed. Therefore, the amount of seawater passing through the circulation hole 4 is always constant. Therefore, since the rotation of the turbine 8 is also stabilized, stable power can be obtained from the generator 10.

[0015]

The present invention configured as described above has the following effects. (B) The structure is simple and the efficiency is high. If a small power generator is used, it can be installed anywhere on the coast with waves. (B) The cost is extremely low because it does not require expensive energy such as nuclear power, thermal power, or hydraulic power generated by dams, and uses natural energy from the height of waves at the edge of the waves and the movement of seawater. (C) Even when a high wave comes, the seawater flowing from the inflow chamber 1 to the discharge chamber through the circulation hole is stable, so that stable power can be obtained.
