Description

  The present invention relates to wind power generation, and more particularly to floating offshore wind power generation used on a deep sea where a self-stabilizing vertical axis wind turbine is installed.

In recent years, power generation that does not use oil or coal has been attracting attention as part of measures to deplete petroleum resources and global warming.
In particular, since the Fukushima nuclear power plant accident caused by the Great East Japan Earthquake last year, attention has been focused on renewable energy other than nuclear power, oil, and coal.
Among them, solar power generation and wind power generation are playing an important role.

  With regard to solar power generation, small-scale power generation installed on the roof of each household has an advantage because the roof space can be used effectively. However, in the case of large-scale solar power generation, it is necessary to install solar panels with a large area. In this case, however, green areas such as forests and fields will be crushed instead, from the viewpoint of measures against global warming. Would go backwards, which is undesirable. That is, in the case of photovoltaic power generation, for example, if 100 energy is obtained, the green space corresponding to 100 is lost. For example, even if the land is currently idle, in the event of a food crisis due to a global population explosion that will come in the near future, the land needs to be used for immediate food production, In that case, the solar panel will be removed, which is not suitable for permanent energy measures.

On the other hand, in the case of wind power generation, for example, as a result of absorbing solar energy in the wide ocean, strong winds are generated and come to Japan, compared to solar power generation from the viewpoint of energy collection, accumulation and integration There are far greater benefits. In other words, since the heat energy accumulated in the ocean is much larger than the area of Japan, there is almost no green space used for wind power generation.
Of course, a facility for processing the electric power sent from the offshore power generation facility by the submarine cable is necessary on land, but a large area is not necessary.

As for wind power generation, horizontal axis wind turbines currently occupy the mainstream, but most of them are installed on land, and there are private houses nearby, so installation is not progressing due to problems such as noise. There are also regions. Japan, for example, is just an example.
In the case of a horizontal axis wind turbine, the load around the wind turbine axis is uneven, and it is very difficult to maintain verticality.Furthermore, it is necessary to always face the wind, so it can respond to rapidly changing wind directions. Is very difficult.
This is especially true for offshore power generation, especially in the case of deep seas of 100m or more, which occupies 60% or more of the entire earth. There are high hurdles and it is difficult to realize.

  In the case of a vertical axis windmill, the center of rotation of the windmill and the center of the windmill mounting tower completely coincide with each other.

  In this way, offshore wind power generation is very important for the country surrounded by the sea, and there is no doubt that it will become mainstream from now on. Installation of floating wind power generation is a necessary condition when there is water depth, but such horizontal axis wind turbines are not practically used anywhere in the world. In particular, in areas where there is water depth and the wind direction changes rapidly, vertical axis wind turbines that do not care about the wind direction are effective, and recently, a lot of attention has been tried around the world. No promising method has been reported.

  Consider efficient use of vertical axis wind turbines under various wind conditions and effective protection measures.

Problem 1 is to prevent the windmill from rotating and destroying it under any strong wind.
Generally, when a strong wind such as a typhoon blows, a measure is taken to forcibly stop the windmill by a brake or the like to prevent the windmill from being damaged. In this case, a powerful braking system is required for the energy of a powerful typhoon, which causes problems such as the necessity of improving the strength of the windmill and cost increase. Furthermore, when a strong turbulence such as a typhoon is swirling, a specific windmill blade that is stopped may receive a large force in a concentrated manner, and there is a risk that destruction is concentrated. If it is rotating, such a force is dispersed and averaged, so it is difficult to cause a problem.
Furthermore, if the windmill is stopped under a strong wind, the energy of a powerful typhoon will be wasted.

Issue 2 is to maintain the verticality of the floating structure under any wind conditions.
Whether it is a horizontal axis wind turbine or a vertical axis wind turbine, if the wind turbine axis is tilted by repeated strong winds and waves from typhoons, hurricanes, etc. It is possible and causes troubles. Under any wind conditions, it is essential to ensure the verticality of the windmill axis and calm down the vertical movement.

Issue 3 is to not adversely affect marine life in the surrounding waters where offshore wind turbines are installed.
In order to perform large-scale power generation on the ocean, it is necessary to install a large number of windmills. In this case, the marine organisms such as marine plants and fishery products should not be adversely affected in the sea area where they are installed. Therefore, it is essential to not cut off sunlight or tidal currents. This makes it possible to collaborate with fisheries and to deploy offshore wind power generation in a wide area in a short time.

Issue 4 is to be as maintenance-free as possible with as few troubles as possible.
Offshore wind power generation requires long-time unmanned operation in deep waters away from land, but maintenance-free is an important condition for that. However, most of the wind turbines currently in use use a generator with a speed increasing gear for both the horizontal axis wind turbine and the vertical axis wind turbine. This type of generator is indispensable for regular maintenance due to gear wear. This has problems such as periodic interruption of power generation and maintenance costs.
In order to cover a considerable amount of power generation by offshore wind power generation, the above problems 1 to 4 need to be completely solved.

Hereinafter, the present invention will be described with reference to embodiments shown in the drawings, but the present invention is not limited to the embodiments shown in the drawings.
As the name suggests, the present invention will first describe measures for achieving self-stabilization of a vertical axis wind turbine.

FIG. 1A is a perspective view showing a buoyancy structure in which a self-stabilizing vertical axis wind power generation unit is incorporated. A posture stabilizing ballast 23 is installed at the lower part of the main float 21 via the coupling structure 22, the wind turbine shaft 4 is installed at the upper part of the main float 21, and the wind turbine is installed at the upper end thereof.
FIG. 2 is a diagram illustrating the water level adjustment of the buoyancy structure. By injecting a low specific gravity material into the coupling structure under the float by an external signal, the water is replaced with a light material, so that the buoyancy structure is lightened and the buoyancy structure is lifted up.

FIG. 2B is used when the waves are high in a state where they are slightly sinking.
Fig. 2 (C) is used when the main float part is also submerged, in case of strong waves or high tsunamis, but the main float is also submerged, so it is not easily affected by waves and the windmill axis is intense. It is possible to suppress vertical movement.
The external signal is a sensor signal such as a water level, a wave amplitude, a vertical movement width of a buoyancy structure, a danger signal based on a typhoon or a tsunami from an external control center, and the like.

Since this buoyancy structure can maintain a stable posture against high waves, a tidal power generation unit and a wave power generation unit can be provided side by side.

  FIG. 5 is a perspective view of a buoyancy structure system in which two buoyancy structures 22 are rotatably coupled by two horizontal struts 24 to form a parallelogram, and FIG. 6 is a side view. Since this system is rotatably coupled so as to form a parallelogram by two horizontal columns 24, even if one buoyancy structure 22 is inclined by a strong wave or the like, the other buoyancy structure 22 There is no problem because it is held.

FIG. 7 shows that the above two buoyancy structures 22 can be rotated by two horizontal struts 24 by an additional buoyancy structure 22 disposed at a position forming an isosceles triangle with the two buoyancy structures 22. It is a perspective view in the state where it is connected to and is going to form a triangle. The three buoyancy structures 22 are connected by two horizontal struts 24 each.
FIG. 8 is a perspective view showing a state in which the triangular combination is completed from the state of FIG. 64 described above.

FIG. 9 shows the results of experiments showing the perpendicularity maintaining characteristics of the buoyancy structure against the vertical movement of the wave.
Data was obtained by changing the buoyancy size of the buoyancy structure in three stages.
(1) Weight-3 buoyancy = 2 × (Weight-2 buoyancy) = 2 × [1.5 × (
Weight-1 buoyancy)]
(2) Tilt angle of the floating structure relative to the tilt angle of the horizontal support (parameter = buoyancy)
(3) Result → For example, for the maximum tilt angle of 11.2 ° of horizontal struts * Weight-1 tilt angle = 5 °
* Weight-2 tilt angle = 4.3 °
* Weight-3 tilt angle = 1.7 °
When calculated, the attenuation effect of Weight-3 = 1.7 ° / 11.2 ° = 0.15 = 15%
That is, Weight-3 was able to suppress the inclination of the floating structure to 15%.
If the buoyancy of the floating structure is further increased, the damping effect may be further increased.
The graph of FIG. 10 represents the attenuation effect.
This actually proves the effect of the present invention.

FIG. 11 shows a state in which the sacrifice 25 is arranged at the center of the triangular coupled buoyancy structure.

FIG. 14 shows a state where the ginger is sinking to the bottom.

FIG. 29 shows an enlarged state of the rotational coupling portion of the four horizontal struts.
FIG. 20 is an enlarged view of the rotational coupling portion of the six horizontal struts.

FIG. 19 shows the possibility of a multi-purpose system in which the number of wind turbines can be increased to the above-described triangular buoyancy structure system by using the same method as in FIGS. Is shown.
FIG. 20 is a perspective view showing a seven-span offshore wind power generation system increased by such a method.

The feature of this system is that the height of the horizontal wire 69 connected to the buoyancy structure does not change by floating the external float 73 on the surface of the water, regardless of the water level. Pulling at the position does not adversely affect the verticality of the buoyancy structure.
FIG. 32 is a modified version of FIG.

Floating wind power generation in deep water is the most targeted field of the present invention, and is expected to be able to start up and operate at an early stage through collaboration with fisheries, etc., and to supply a considerable proportion of future power requirements. Is done.
Furthermore, according to the present invention, the wind turbine is a vertical axis wind turbine that does not care about the wind direction, and since the vertical blades can be bent by rotation, it is possible to avoid damage due to excessive force such as gusts and high speed rotation. . This makes it possible to operate stably for a long time without a person.

  For example, a large number of windmills can be installed if they are installed at regular intervals in a vast and long space such as an expressway or a bullet train, and it is possible to cover a certain proportion of the required power. In this case, the noise problem is not a problem in both cases, so it is not so difficult to obtain the understanding of the local residents and others concerned about the installation.

  Furthermore, when looking overseas, desertification is progressing in various places due to global warming phenomenon, but a huge number of windmills are installed in this area, and the groundwater is directly pumped by taking advantage of the characteristics of the vertical axis windmill. I can do it. Alternatively, if the groundwater can be pumped up by the electric power generated by the vertical axis wind turbine, or if water can be generated and greening can be promoted, changing the desert to green space should not be a dream, and the inventor will I am willing to work hard so that I won't end it with a dream.
