使用に供している。This sunlight collection device section 10 includes a large number of solar panels (for example, 7, 19, etc.) for collecting sunlight.
□ to 11n, a sunlight direction sensor 12 for detecting the direction of the sun, and a support frame body 13 for holding these together and fixing the light receiving end of a light guide (not shown) at the focal position of the lens. , a first rotation shaft 14 for rotating the support frame main body 13, a first motor 15 for rotating the first rotation shaft 14, and a support arm for supporting the lenses 111 to 11n to the motor 15. 16, a second rotating shaft 17 disposed perpendicular to the first rotating shaft 14, and a second motor (not shown) that rotates the second rotating shaft 17. The direction of the sun is detected by the sensor 12, and the lenses 11□ to 1 are
A light conductor cable (not shown) whose light receiving end is arranged at the focal position of each lens controls the first and second motors so that the motor 1n always faces the sun, and receives sunlight focused by the lenses 111 to 11n. The light is introduced into a light guide cable and transmitted to any desired location for illumination or other purposes.

、太陽光を効率よく収束することができなかった。Therefore, in the above sunlight collecting device, the capsule is fixed, and only the solar collecting device section inside is movable, and since the movable section moves to follow the movement of the sun, the capsule and the sunlight collecting device are The relative position of the capsule with the lens changes from time to time, but the capsule is not necessarily formed uniformly.
In addition, the angle of incidence of sunlight on the capsule changes over time, and when it passes through the capsule, the angle of incidence on the lens changes (no longer at a right angle).
, it was not possible to efficiently converge sunlight.
上述のごとき不具合を解決するために、本出願人は、先

及び１７の軸まわりに回動するように構成されている。In order to solve the above-mentioned problems, the present applicant previously proposed a sunlight collecting device as shown in FIG. In FIG. 4, reference numeral 20 denotes a housing that integrally houses the sunlight collecting device section 10, and at least the front surface of the housing 20, that is, the surface facing the lenses 11□ to 11n, is composed of a transparent body 21. The body 20 has lenses 111-11. along with axis 14
It is configured to rotate around the axes 1 and 17.

維持して太陽光を収容することができる。Therefore, according to this sunlight collecting device, since the sunlight collecting device section 10 and the housing 20 rotate integrally, the transparent body 21
and lenses 11□~11. The relative relationship of is always the same,
If the positional relationship between the transparent body, the lens, and the light-receiving end of the light guide is fixed at the best position during manufacturing, this best relationship can be maintained from now on to accommodate sunlight.

難であった。However, in the above sunlight collecting device, the first rotating shaft 14 including the support arm portion 16 protrudes to the side of the housing 20, and the outer diameter thereof is increased accordingly. Therefore, the effective sunlight collecting area is the total area of the lens, and other areas are invalid areas, and the area occupied by the solar collecting device when viewed from the front (lens surface side) is In particular, when a large number of similar solar collectors are installed, the installation area of the solar collectors becomes large, making it difficult to secure the space.

を介して該軸１７のまわりに回動することができる。The light-receiving surface of the front cylindrical body 20a is covered with a transparent plate 21 fixed by fixing means such as bolts, and the front cylindrical body has a sufficient area to accommodate a large number of light collecting lenses. A longitudinally elongated rear cylindrical body 20b having a diameter smaller than the diameter of the front cylindrical body 20a is fixed coaxially behind the front cylindrical body 20a. The first rotation shaft 14 is fixed to the rear cylindrical body 20b, and the rotation transmission device 15a and the shaft 6
The first motor 15 supports the first motor 15.
Rotated. Further, the inside of the rear cylindrical body 20b is configured to have the same rotational moment as the front cylindrical body 20a with respect to the first rotation axis 14. Based on the calculation results, the first. A control command unit 23 that issues control commands to the second motor is housed. Note that if the weight of the control command section 23 is not sufficient to make the rotation moment constant, it is adjusted by adding a weight. By making the moments equal, not only is the mounting stable, but the responsiveness is improved, and the first motor 15 can also be rotated with a small torque. Similarly, if the left and right rotation moments of the second rotation axis 17 are made equal, the response speed of the second rotation axis will be increased,
Moreover, the drive motor can be downsized. Furthermore, the first
The sunlight is in a positional relationship perpendicular to the axial direction of the rotating shaft 14, and the distance between the bearing 15b and the rotating shaft transmission mechanism 15a is selected to be smaller than the outer diameter of the front cylindrical body. The drive means of the shaft 14 are not exposed to sunlight. Conversely, sunlight effectively irradiates the sunlight collection unit 10. Therefore, the U-shaped support arm 16 that supports the first rotating shaft 14, in which the motor 15, the rotation transmission mechanism 15a, and the bearing 15b are disposed, and in which the light guide is inserted, can also be made small. The gears 18a and 18b that transmit the rotation of the second motor 18 are compactly accommodated in the base portion 30, and the second rotation 17 is
It can be rotated about the axis 17 via.

The effective area ratio can be maximized, and since the rotation moment around the horizontal axis and around the vertical axis are equalized, the rotation is stable, and the drive torque can be reduced, making it possible to use a small motor. can.
