FIG. 3 is a back view, and in the figure, 1 is a Fresnel lens for concentrating sunlight, and the Fresnel lens 1 is formed into a regular hexagon as shown in the figure, with one Fresnel lens disposed in the center. , each side of the Fresnel lens disposed at the center is arranged so that one side of another Fresnel lens touches. Reference numeral 2 denotes a sunlight collection unit for collecting sunlight focused by the Fresnel lens 1, and the sunlight collected by the sunlight collection unit 2 is guided to a desired location through a light conductor cable 3. He, there electric energy,
It is converted into thermal energy or the like, or used as is as light energy. 4 is a connecting rod for integrally configuring the Fresnel lens 1 and the sunlight collection unit 2; 5a, 5b, and 5c are holding plates for holding the Fresnel lenses arranged as described above; and 6 is a holding plate. 5a and 5c are connected to support arms, 7 is a rotating vertical shaft, 8 is a vertical shaft motor, 9 is a radial bearing, and 10 is a thrust bearing; the Fresnel lens or the holding plate is supported by the supporting arm 6 and the rotating vertical shaft 7; It is rotatably supported around a rotating vertical shaft 7. Further, 11 is a horizontal axis of rotation, and 12 is a horizontal axis motor, and the horizontal axis motor 12 is attached to a holding plate 5a or 5c, so that the Fresnel lens or the holding plate can be rotated around the horizontal axis of rotation 11. . Therefore, if the position of the sun is detected by a detection device (not shown) and the vertical axis motor 8 and horizontal axis motor 12 are controlled by the output signal, the Fresnel lens can automatically follow the movement of the sun and detect the sun. Since light can be collected efficiently and the rotation angle of the Fresnel lens can be set to 360° or more with respect to the vertical and horizontal axes, for example, the sunlight collecting device according to the present invention can be used in the northern hemisphere. It can be used without any problems even when used in the southern hemisphere.
In addition, when used on a ship, it can be used without any problem even if the bow of the ship is facing in any direction. Reference numeral 13 denotes a transparent sealed container, and by sealing the Fresnel lens, etc. with the transparent container 13, it is possible to prevent dust from adhering to the Fresnel lens, etc., and to prevent the tracking movement from being disturbed by wind or the like. This prevents the As mentioned above, when a Fresnel lens for concentrating sunlight is collected in a transparent spherical container and is rotatable in any direction, the sun light formed by the Fresnel lens It is clear that a Fresnel lens can be accommodated in a spherical container most efficiently by making the light receiving surface circular, in other words, with the widest light receiving area.As mentioned above, each Fresnel lens is formed into a regular hexagon. However, if one Fresnel lens is placed in the center, and one side of the other Fresnel lenses touches each side of the Fresnel lens placed in the center, there will be no gaps between the Fresnel lenses. , it becomes possible to arrange the entire light-receiving surface to be approximately circular, which makes it possible to form the solar light-receiving surface most effectively, and moreover, the entire light-receiving surface can be arranged on vertical and horizontal axes within the spherical container. It is possible to rotate more than 360 degrees. Although an example in which seven Fresnel lenses are used has been described above, the present invention is not limited to the above embodiment. For example, 12 Fresnel lenses are used outside the embodiment shown in FIGS. total by placing two Fresnel lenses adjacent to each other.
It is possible to configure it using 19 Fresnel lenses, and it is also possible to configure it with 18 Fresnel lenses adjacent to the outside, for a total of 37 Fresnel lenses. is, N=
It can be configured with 3n(n+1)+1 (where n=natural number) Fresnel lenses.

ができる。 As is clear from the above explanation, according to the present invention, a regular hexagonal Fresnel lens which is closest to a circle and has the highest light collection efficiency per unit area among the Fresnel lenses that can be installed quickly is used. Since multiple Fresnel lenses are used to make the entire light-receiving surface almost circular, multiple Fresnel lenses can be arranged in a spherical container in the most efficient way to collect sunlight energy. Further, the tracking operation of the Fresnel lens can be performed smoothly and over a wide range.
