Abstract
A frame body (3) is suspended at multiple positions by wires (15) from a support section (11) formed at the center of the frame body (3). Although simple in structure, the frame body (3) does not deflect. Because the frame body (3) has the simple structure, the weight of the entire device is reduced. Further, tension is applied to multiple positions of the frame body (3) from below by wires (15), and this prevents the frame body (3) from deflecting even if wind blows against a mirror structure (5).

Support column parts 11 and 12 are formed on the light receiving central frame part 7 in the vertical direction and fixed to the frame body 3. In addition, hook portions 13 and 14 are formed on the top and bottom of the four corners of the third frame 3c and in the vicinity of the four corners of the first frame 3a, respectively. And the piano wire as the metal wire 15 is stretched between the front-end | tip of the up-and-down support | pillar parts 11 and 12, and the hook parts 13 and 14, It becomes the structure where the frame body 3 was suspended with the wire 15.

中央フレーム部７における赤緯軸８の上側にオフセットした位置には、駆動バー１６が貫通した状態で設けられている。この駆動バー１６は両端部がミラー構成体５よりも外側に突出する程度の長さを有している。
In the center frame portion 7, the drive bar 16 is provided at a position offset to the upper side of the declination axis 8. The drive bar 16 has such a length that both ends protrude outward from the mirror structure 5.
駆動バー１６の両端には下向きの調整部１７が設けられ、調整部１７の上下にはフック部１８が形成されている。調整部１７の上側のフック部１８は、保持柱９のの途中部分に設けられたフック部１９とワイヤ１５を介して連結されている。調整部１７の長さは、赤緯軸８に対する駆動バー１６のオフセット量に相当し、調整部１７の下側のフック部１８の位置は、ちょうど赤緯軸８の延長線上に位置する。
Downward adjustment portions 17 are provided at both ends of the drive bar 16, and hook portions 18 are formed above and below the adjustment portion 17. The hook portion 18 on the upper side of the adjusting portion 17 is connected to a hook portion 19 provided in the middle portion of the holding column 9 via a wire 15. The length of the adjustment portion 17 corresponds to the offset amount of the drive bar 16 with respect to the declination axis 8, and the position of the hook portion 18 on the lower side of the adjustment portion 17 is located just on the extension line of the declination axis 8.
また、調整部１７の下側のフック部１８には、チェーン２０が取付けられ、架台ベース１に設けられた駆動ボックス２１にローラー２２を介して導かれている。
Further, a chain 20 is attached to the lower hook portion 18 of the adjusting portion 17 and guided to a drive box 21 provided on the gantry base 1 via a roller 22.
図８に示すように、駆動ボックス２１には、２つのローラー２２の間に、モータ駆動により回転する１つのチェーンブロック２３が設置されている。チェーンブロック２３はチェーン２０と係合した状態で、回転することにより、チェーン２０を送り出すことができる。また、このチェーンブロック２３は調整方向Ｄへ付勢されており、常にチェーン２０に対してテンションを付与した状態になっている。
As shown in FIG. 8, the drive box 21 is provided with one chain block 23 between the two rollers 22 that rotates by driving the motor. The chain block 23 can be sent out by rotating in a state in which the chain block 23 is engaged with the chain 20.

The chain 25 is coupled to the tip of the support column 11 at the lower portion, and is guided to the chain block 26 in the central frame portion 7 via another roller 24 at the upper portion. Therefore, the chain 25 can be sent out by the rotation of the chain block 26. The chain block 26 is also urged downward.
次に作用を説明する。
Next, the operation will be described.
駆動ボックス２１内のチェーンブロック２３をモータ駆動により回転させると、チェーン２０がどちらかに送り出されるため、駆動バー１６の一端が引かれて、ミラー構成体５全体が極軸２を中心として、太陽の日周方向へ回転する。ミラー構成体５には図示せぬ太陽センサーが設けられ、チェーンブロック２３を回転制御することにより、ミラー構成体５が常に太陽を向いた状態となる。ミラー構成体５が太陽を向いた状態になると、複数の反射ミラー４にて形成された球面鏡で反射された太陽光Ｌがスターリングエンジン１０に集光し、スターリングエンジン１０で発電をすることができる。
When the chain block 23 in the drive box 21 is rotated by a motor drive, the chain 20 is sent out to one side, so that one end of the drive bar 16 is pulled, and the entire mirror structure 5 is centered on the polar axis 2 with the sun. Rotate in the diurnal direction. The mirror structure 5 is provided with a sun sensor (not shown), and by controlling the rotation of the chain block 23, the mirror structure 5 always faces the sun. When the mirror structure 5 faces the sun, the sunlight L reflected by the spherical mirror formed by the plurality of reflecting mirrors 4 is condensed on the Stirling engine 10 and can be generated by the Stirling engine 10. .
また、季節によりミラー構成体５の向きを赤緯方向に回転させる必要があるが、その場合も中央フレーム部７内に設けられたチェーンブロック２６が回転することにより、ミラー構成体５が赤緯軸８を中心に回動して、最適な向きとなる。
Further, it is necessary to rotate the mirror structure 5 in the declination direction depending on the season. In this case as well, the mirror block 5 is declinated by rotating the chain block 26 provided in the central frame portion 7. It rotates about the shaft 8 to be in an optimum direction.
この実施形態によれば、フレーム体３の複数箇所を、フレーム体３の中心に形成した支柱部１１からワイヤ１５による吊っているため、フレーム体３を単純構造にしても、フレーム体３が撓むことがない。フレーム体３を単純構造にできるため、全体重量の軽減化を図ることができる。
According to this embodiment, since a plurality of locations of the frame body 3 are suspended by the wires 15 from the support column 11 formed at the center of the frame body 3, the frame body 3 is bent even if the frame body 3 has a simple structure. There is no excuse. Since the frame body 3 can have a simple structure, the overall weight can be reduced.
また、フレーム体３の複数箇所を、下からもワイヤ１５によりテンションを付加しているため、ミラー構成体５に対して下から風が吹き付けられたような場合にも、フレーム体３の撓みを防止することができる。すなわち、赤緯軸８に位置固定された中央フレーム部７および支柱部１１，１２からなる構造体がワイヤー１５の張力を発生し維持することができる。
In addition, since tension is applied to the plurality of locations of the frame body 3 from below with the wires 15, the frame body 3 can be bent even when wind is blown from below on the mirror structure 5. Can be prevented. That is, the structure composed of the central frame portion 7 and the column portions 11 and 12 fixed to the declination axis 8 can generate and maintain the tension of the wire 15.
更に、フレーム体３の中央フレーム部７に赤緯軸と平行な駆動バー１６を形成し、その駆動バー１６の両端部に駆動力を作用させるため、小さい駆動力でもミラー構成体を確実に回動させることができる。小さい駆動力で回動させることができるため消費電力が少なくて済む。
Further, since the drive bar 16 parallel to the declination axis is formed in the central frame portion 7 of the frame body 3 and the drive force is applied to both ends of the drive bar 16, the mirror structure can be reliably rotated with a small drive force. Can be moved. Since it can be rotated with a small driving force, it consumes less power.
加えて、駆動力は駆動バー１６に作用するだけで、フレーム体３に直接作用しないため、駆動力によるフレーム体３の撓みも防止することができる。
In addition, since the driving force only acts on the driving bar 16 and does not directly act on the frame body 3, it is possible to prevent the frame body 3 from being bent by the driving force.
