The present invention relates to a solar tracking device that tracks the direction of the sun and enhances the efficiency of collecting sunlight.

尽蔵且つ無償で利用出来る太陽光発電が注目されてい

ー変換効率は10〜15％と低効率である為に、該発電装置
の設置コストの回収期間が数年以上と極めて長く、商用
化を妨げる大きな要因となっていた。However, in this type of power generation system, the price of silicon as a solar cell material is high, and its energy conversion efficiency is as low as 10 to 15%. Therefore, the recovery period of the installation cost of the power generation device is several years. The above is extremely long, and has been a major factor that hinders commercialization.

質的な集光効率の向上は何等図り得ないことは言うまで
もない。For this reason, in order to increase the energy conversion efficiency from the past, we are attaching a Frennel lens or other light condensing mechanism to the front surface of the solar cell array, and are conducting research and development of a hybrid system for cooperative use of sunlight and solar heat. However, even if such a system is developed, it is essential that the solar cell array can rotate by tracking the change in the direction of the sun rays from sunrise to sunset, unless a sun ray tracking device is attached. Needless to say, it is impossible to improve the light collection efficiency.

設置コストの増加に比較してそれ程のエネルギー変換効
率の向上を図り得ないという問題を有していた。As the configuration of the tracking device, for example, a large number of solar cell arrays are installed on a rotary mount that rotates in a horizontal plane, and a plurality of optical sensors (photodiodes, etc.) having an angular difference in the rotation direction of the rotary mount are rotated. Provided on the pedestal, detects the positional deviation between the light receiving surface of the solar cell array and the sun rays based on the difference in the amount of light received between the optical sensors, while rotating the rotary pedestal following the azimuth change of the sun rays. , There is a device for tracking the sun's rays (Japanese Patent Laid-Open No. 58-193510, etc.) "Problems to be solved by the invention" However, in such a conventional technique, a large number of solar cells are mounted on the rotary mount. Since the solar cell array supporting member and the like are mounted together with the array, and the rotary platform itself supporting these also requires a predetermined strength, the weight burden of the rotary platform is extremely large. Therefore, the drive energy required to drive the rotary mount is inevitably large,
There was a problem that the energy conversion efficiency could not be improved so much as compared with the increase in installation cost.

固に且つその回転時に生じる摩擦抵抗等についても極力
少なくなるように設計しなければならず、機構の複雑化
と共に装置全体が大型化し、設置コストが増加するとい
う欠点を有す。Further, in the above-mentioned conventional technique, since the weight of the rotary mount is heavy, the support base for rotatably supporting the rotary mount is designed to be strong and the frictional resistance generated during the rotation is minimized. However, it has a drawback that the apparatus becomes large and the installation cost increases as the mechanism becomes complicated.

(EN) Provided is a solar light tracking device capable of supporting and driving a rotary mount.

る。"Means for Solving Problems" The present invention relates to a substantially flat-shaped pedestal that is floated on a liquid surface with buoyancy and is rotatably and vertically movable on a fixed shaft. It comprises a solar-powered device installed on a pedestal, a rotating means for rotating the gantry along a liquid level in a horizontal plane, and a means for detecting a positional deviation between a light-receiving surface of the solar-powered device and a sun ray. By driving and controlling the rotating means based on the detection signal from the position shift detecting means, the mount is predetermined along the liquid surface so that the light receiving surface of the sunlight utilizing device is located at the optimum light receiving position. It is characterized by rotating at an angle.

力を内包し該架台を液面と同位置に維持せしめてもよ
く、又架台と別個に浮力付勢手段を付設して、架台が液
面より上方に位置せしめてもよい。The floating on the liquid surface of the rotary mount may be such that the mount itself contains buoyancy to keep the mount at the same position as the liquid level, or a buoyancy biasing means is provided separately from the mount. The pedestal may be positioned above the liquid surface.
この場合、前記回転架台を浮かす液面は一般に、湖、
池、川、海等の水面を指すが、必ずしもこれに限定され
るものではなく、油面、例えば前記回転架台を原油タン
クの浮き屋根に兼用して用いることも可能である。In this case, the liquid level floating on the rotary mount is generally a lake,
It refers to the water surface of a pond, a river, the sea, etc., but is not necessarily limited to this, and it is also possible to use the oil surface, for example, the rotary mount as a floating roof of a crude oil tank.
又、前記固定軸は、架台中心線上に沿って液内に垂設す
るのがよく、これにより架台を液面に沿って水平面内で
回転させる事が容易となる。Further, it is preferable that the fixed shaft is vertically installed in the liquid along the center line of the gantry, which makes it easy to rotate the gantry along the liquid surface in a horizontal plane.

が海面下に没しない。Even when the pedestal is rotatably floated above the sea surface, the fixed shaft supporting the pedestal is rotatably and vertically movable. Also, between the fixed shaft and the gantry is configured to be expandable / contractible according to the change in the liquid level, so that the solar-powered device mounted on the gantry does not sink below the sea level.

ることなく半永久的に前記追尾が可能となる。Further, as is well known, the position shift detecting means is an optical sensor for detecting a change in the amount of light received by the solar light utilizing device, and the rotating means is a motor for rotating the gantry at a predetermined angle based on the detection signal of the optical sensor. It is also possible to configure with the drive means, for example, the position deviation detection means is configured by a pair of solar cells installed on a pedestal and mutually different in light receiving direction, and depending on the output difference of the pair of solar cells, By configuring the gantry so that it can rotate along the liquid surface by a predetermined angle, the circuit configuration is simplified, and the tracking can be performed semipermanently without requiring a special drive source.
尚、前記太陽光利用機器とは太陽電池アレイ、太陽光集
熱板のみに限定されるものではなく、他の全ての太陽光
利用機器を含む。In addition, the said solar utilization equipment is not limited only to a solar cell array and a solar heat collecting plate, and includes all other solar utilization equipment.

ネルギー及び駆動源自体を極めて小さくさせることが出
来る。[Operation] According to the technical means, since the gantry on which the solar light-utilizing equipment is mounted has buoyancy and is floated above the liquid surface, the weight burden of the gantry can be reduced to almost zero. Since the rotation direction of the gantry is rotation in the horizontal plane along the liquid surface, the drive energy of the rotating means for rotating the gantry and the drive source itself can be made extremely small.
従って前記架台の回転、即ち追尾駆動を行う駆動源が小

である。Therefore, the rotation of the gantry, that is, a small drive source for performing the tracking drive, has a sensor function provided for detecting the positional shift between the light receiving surface of the solar light-using device and the sun's rays. It is also possible to perform tracking drive of the pedestal only with the output of the solar cell, and as a result, it is semi-permanent without using any electromotive force of the array mounted as a solar-powered device and no need to obtain power from the outside. It can be used for various purposes.
又前記架台が略偏平状であることは、液面での安定性が
良好でもあり、而も液面に沿う水平面内での回転を精度
よく且つ安定して行うことが出来る。Further, since the gantry is substantially flat, the stability on the liquid surface is also good, and rotation in the horizontal plane along the liquid surface can be performed accurately and stably.
