DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates generally to a wind wave power generator, and more particularly to a power generator using power obtained by combining wind power and wave power. More particularly, the present invention relates to a wind wave power generation device having both windbreak and wavebreak.

[0002]

2. Description of the Related Art Conventionally, in urban development on the sea, means for preventing a strong wind blown from the sea like a windbreak forest on land is required. The trees in the windbreak forest absorb the energy of the wind by the sway of the branches and leaves and the trunk, convert it to heat, and at the same time, change the direction of the wind to the sky to exert the windbreak effect. However, on the sea, it is difficult to plant a windbreak forest with trees due to salt damage.

On the other hand, there is a windmill as a means for converting wind energy into electric energy or the like. Since a windmill such as a power generator converts wind into energy or the like, the wind power after passing through the windmill is weaker than the wind power before hitting the windmill.
Using this fact, wind turbines can play the same role as trees in windbreak forests.However, there is a drawback that existing wind turbines may be damaged if they are hit by strong winds such as typhoons. The function to reduce the strong wind is not considered at all. Most of this drawback lies in the centralized hub part of existing wind turbines.

[0004] Wind turbines that do not use a centralized hub include a vertical axis wind turbine, which includes a paddle type, a Savonius type, a gyromill type, a Darius type, a Voith Schneider type, and others. Has a weakness. this. Paddle-type, Savonius-type, gyromill-type, Darius-type, Voithschneider-type, and other vertical-type windmill blades can be applied to the present invention.

[0005]

However, the conventional wind power generator is a generator using only wind energy, and the wave power generator is a generator using only wave energy. Therefore, unlike land, power generation on the open water surface without obstacles was overlooked without picking up one energy.

At the same time, when a marine city or marine marina is built, the wavebreak and windbreak are considered separately, and it is completely unthinkable that the efficiency that all of them are combined and solved simultaneously is considered. .

[0007]

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a water floating windbreak / wind wave power generator according to the present invention. FIG. 1 is an end view of a side cross-section of an embodiment of a waterborne windbreak / wind wave power generation device according to the present invention. FIG. 2 shows a plan view of FIG. FIG. 3 shows an enlarged side view near the power transmission casters. FIG. 4 is an enlarged cross-sectional plan view of a portion where the power transmission caster contacts the floating body. FIG. 5 is a development view of one embodiment of the rotation trajectory in the wind rotation and the vertical movement of the wave where the power transmission caster is in contact with the surface levitation body, and the horizontal direction indicates the rotation direction of the surface levitation body. The vertical direction indicates the vertical movement direction of the water floating body due to the wave.

First, there is a hollow ring 1 provided in a huge cylindrical shape. In the drawing, the size of this circumference is very small with respect to the size of the hollow ring 1 etc., but this is done so that the hollow ring 1 etc. can be easily understood, and in fact the diameter is several tens of kilometers. It is a size that can be done. Of course, a small circumference can be used, all of which are determined by the magnitude of the power generation and the intended use of the water surface within the circumference. However, since this hollow ring 1 is completely enclosed, no matter how rough the sea is, it floats like a buoy and does not sink. In addition,
The inside 1a of the ring 1 may be hollow as shown in FIG. 1, but if it is floating on water, the inside 1a may be hollow.
It may be one in which a is clogged.

Next, a number of wind wings 2 such as sails of a sailing ship
There is. The large number of wind receiving blades 2 are provided on the above-mentioned hollow ring 1. And there is a wind receiving angle control means 3. This is to change the angle of the wind receiving blade 2, and when the rotation direction of the hollow ring 1 is in the direction of blowing the wind, the wind receiving blade 2 receives the wind to the maximum, and the reverse direction. In such a case, the wind resistance should be minimized. Further, there is mooring means 4.
This anchors the hollow ring 1 described above.

And there is a power transmission caster 5. As shown in an enlarged side view of this portion shown in FIG. 3 and a plan sectional view of FIG. 3 shown in FIG. 3, the power transmission caster 5 is provided between the mooring means 4 and the hollow ring 1 in a horizontal direction. It is provided in. Finally, there is a generator 6. This is operated by the rotational power from the power transmission caster 5 described above. The ebb and flow of the tide slightly contributes to this power generation.

As shown in FIG. 6, a part of the hollow ring 1 is broken, and the broken part 1a is connected below the surface of the water by the connecting means 7, so that the broken part becomes a ship passage. It is made up of Of course, the missing portion of the hollow ring 1 is not entirely missing, but only has an upper portion excluding a portion in contact with the power transmission caster 5. The defect has a depth such that the bottom of a ship passing therethrough does not contact the defective portion. And
The ship entering or leaving the inland water surface 1c is rotated in the direction of rotation of the hollow ring 1 in accordance with the rotation speed of the hollow ring 1 appropriately, and when the ship comes to the defective portion 1b, it is inclined in the direction of rotation. By moving the ship toward, the ship can enter and exit the inland water surface 1c. Of course, the rotation of the hollow ring 1 may be stopped to allow the ship to enter and exit. Further, a ship that is going to enter and exit the ship may be moved by using a manipulator. In FIG. 6, the wind receiving blade 2 is omitted.

The inner water surface 1c of the ring 1 is quiet because it is surrounded by the hollow ring 1 and can be used in a marina or a water city. In addition, this hollow ring 1
It is efficient to arrange as shown in FIG.

[0024]

According to the present invention, the water floating windbreak wave / wind wave power generator according to the present invention has the following advantages. That is, the power electric caster changes the vertical motive force of the wind above the water and the wave of the water surface into a combined rotational force, which is transmitted to a generator to generate power. Therefore, both wind power generation and wave power generation are performed at the same time, and the power generation efficiency is high.

That is, firstly, regarding the windbreak effect, the water surface floating body can be enlarged in diameter up to several tens of kilometers, for example, to several tens of kilometers, and can exhibit a sufficient windbreak effect together with those sails, and also exhibit an effect as a breakwater. it can. In such a giant water surface floating body, a space is formed at the center of the floating surface to form a ring, and the inner water surface can be used as a still water surface. The entrance of a ship or the like can be opened in the ring portion as shown in the figure.

In a small surface floating body, by staggering them, an effective windbreak effect can be exhibited. In addition, a group of small surface floating bodies staggered by a rice planted in a paddy field produces strong wind. It exerts a large wave breaking effect so that the water surface of the paddy field does not ripple even underneath. Also,
Waves hitting small floating bodies are also attenuated. The surface levitation body is not a fragile bearing that the existing windmill has, but to support the surface levitation body with buoyancy,
The resistance to strong winds was significantly increased. The surface levitation body can be provided with a number of power transmission casters mounted on the surface levitation body and the mooring column or the fixed body,
The resistance to strong winds was significantly increased.

Next, the aeration effect will be described. That is, if stirring means is provided on the water surface portion of the water surface floating body, it can be used as an aeration windmill. In that case, the power generator may be omitted.

Finally, the economic effect will be described. In other words, in the development of a floating city, a small ship base, and the like, strong winds and large waves have become a serious bottleneck in the development. Windbreak forests could not be created, and the construction of breakwaters required huge costs. Breakwaters with wave power generators help to recover the cost of embankment by supplying power, but have little windbreak effect.

On the other hand, a small surface floating body can be mass-produced in a factory or a shipyard, and can be installed on the site only by anchoring it at the installation point, thereby reducing production costs and construction (installation).
The cost is dramatically lower. In addition, the energy of wind and waves can be converted into electric energy at the same time.

On the other hand, since the giant water surface floating body can be built in a shipyard because it is a floating body, it is significantly less expensive than the embankment type and the installation work is easy. The construction cost can be recovered by exhibiting both windbreak and wavebreak effects, supplying power and commercial use of the inland water surface. However, since its magnitude greatly exceeds the period of the wave, it is not considered to convert the vertical movement into electric energy.

According to the second aspect of the present invention, in addition to the various effects described above, the efficiency is improved by using the wind receiving angle control means. Furthermore, the invention of claim 3 provides:
By providing a partly missing portion on the surface of the floating body according to the invention of claim 1 or the invention of claim 2, the portion is used as a ship entry / exit location. Therefore, in addition to the various effects described above, a marina, a floating city, or the like can be provided on the inland surface of the ring, and the use thereof has been widened.
