Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention collects sunlight, which is expected as an inexhaustible and clean energy source, as light energy without converting it into other forms such as heat energy and electric energy. The present invention relates to a global light transmission device for sunlight, which is adapted to be transmitted and supplied to a ring-shaped global sunlight transmission cable that makes a round in a direction substantially along a line (latitude) parallel to the equator on the earth.

2. Description of the Related Art Modern humans have relied on fossil fuels such as coal and oil as energy sources, but in recent years the problems of resource depletion and the crisis of the global environment have become more serious. Nuclear energy as an alternative is about safety,
In addition to environmental problems, the current method of using uranium as a raw material still causes resource depletion. Research on fusion technology and hydrogen energy utilization technology as future energy has only just begun and it will take a long time to put them into practical use. In such a situation, humankind must urgently find an infinite and clean energy source for the future. On the other hand, solar energy is about 1
It is pouring into the earth with a huge amount of light energy of 0 kyokcal / hour. This is to cover the total amount of energy required by all human beings for one year with the incident amount for 30 minutes. Moreover, this solar energy is clean (no pollution) and inexhaustible. Therefore, if human beings were able to directly capture and supply light energy from this enormous energy source, sunlight, they would be free from energy insecurity and would have the ultimate energy source.

[0003]

As described above, since solar energy has excellent characteristics as a new energy source such as non-depletion, cleanness, and no local uneven distribution, it attracts attention and is used in various fields. Technology has been developed. Its first development goal is an automatic solar concentrator. The solar automatic light concentrating device has attracted attention since the 1973 oil shock, and has been vigorously developed in each country, and some development results have been achieved in Japan. However, most of the methods of utilizing the sunlight collected by this automatic sunlight concentrator are used in the following two methods.

That is, the conventional technique of utilizing sunlight is divided into a technique of utilizing heat energy and a technique of utilizing light energy. However, all of these are technologies that attempt to use solar energy by converting it into heat storage energy in substances such as water that can be controlled by humans, or by converting it into electrical energy, so the energy conversion efficiency is poor, In general, solar energy is so weak that it is considered too weak to be used for business, and its range of use was limited.

Recently, however, basic techniques such as the method of collecting sunlight as it is, introducing it into a light guide, transmitting it through an optical fiber cable, arbitrarily extracting it as it is, and directly using it are being developed. Became. For example, a solar collector (Japanese Patent Publication No. 62-8762, Japanese Patent Publication No. 63-
5728), solar energy collecting and transmitting device (Japanese Patent Publication No. 59-4624), optical fiber cable for optical energy transmission (Japanese Patent Publication No. 59-4624), optical branching device (Japanese Patent Publication No. 62-56486), Examples thereof include a photoelectric lamp device (Japanese Patent Publication No. 59-23603), an optical radiator (Japanese Patent Publication No. 61-1726), and a photosynthesis device (Japanese Patent Publication No. 60-1875).

In other words, by combining these techniques, it becomes possible to collect sunlight as it is, to introduce it into an optical fiber cable, to transmit it, and to take it out as it is. However, it is not used practically socially. Regarding the method of using an optical fiber, it has been used as a component of an optical communication system and put into practical use by paying attention to its light transmission capacity, but this is not the idea of effectively utilizing solar energy.

The inventor has considered the reason why the solar light collecting and transmitting device which can use the sunlight as the light as it is is not put into practical use. The use of sunlight is related to the movement of the earth (rotation). Therefore, it can be used only during the day when the need is low, and cannot be used during the night when the need is high. Further, the solar power output varies depending on the latitude and season of the earth, and also depends on the weather conditions. Therefore, it is difficult to secure solar energy that is averaged all the time. It is extremely difficult to keep sunlight confined as it is. Due to the technical problems as described above, it was found that practical use thereof is difficult.

[0008] Therefore, as a result of earnest research to solve the above problems, the inventor has conducted a study on a global scale of solar light by combining the solar light concentrating means and the global solar light transmission constituted by an optical fiber cable. Developed a global optical transmission device.

[0009] That is, by making a round on the earth substantially parallel to the latitudinal direction, a ring-shaped global solar light transmission cable is formed which transmits sunlight over the daytime region and the nighttime region. If multiple solar concentrators are installed along the ring-shaped global solar transmission cable, even if the earth rotates, it will always be possible to condense from several solar concentrators in the daytime area. , Regardless of the local weather, it is possible to constantly collect sunlight and introduce it into the fiber optic cable for continued transmission. In this case, it is possible to transmit effectively to a nighttime area or underground space where there is a high need, so that the above-mentioned conventional technical problems can be solved, and the utility and use as a solar energy supply system. The value can be dramatically increased.

Further, an optical fiber cable is arranged on the earth so as to extend around it in a direction substantially parallel to the latitudinal direction to form an annular global solar light transmission cable, and the solar light condensed in the optical fiber cable is formed. Is introduced to keep it in a state of constant transmission and supply. this is,
It is supplying sunlight into a ring-shaped global solar transmission cable so that sunlight can be taken out at any time, and plays a major role in society as a new energy supply facility that supplies solar energy as needed. It can be done.

[0011] In addition, such a global optical transmission device for sunlight requires initial capital investment. However, once the facility is constructed, sunlight is an inexhaustible and clean energy, and There is no need to purchase resources for energy sources, and the cost is only the maintenance cost of the facility. As a result, solar energy costs can be sufficiently economically competitive with other alternative energy costs by developing related technologies such as performance improvement and cost reduction of related equipment, expansion of demand, expansion of production volume. become.

[0012] That is, the present invention is a solar light global concentrating transmission cable device, which is a combination of a ring-shaped global solar transmission cable and solar concentrating means provided so as to be scattered along it. It is capable of collecting and transmitting sunlight at all times regardless of rotation and weather, and functions as a global supply system of light energy.
