Description

本発明は太陽光利用に際して集光効率を増大させるために利用されるヘリオスタットや自由雲台に関する。 The present invention relates to a heliostat and a free pan head used for increasing the light collection efficiency when using sunlight.
太陽光を最適角度で受光するために太陽仰角制御装置や、反射光を集光するためにヘリオスタット等が使われているが(以下太陽光追尾装置と称す)、これらにはサーボ機構やジンバル機構と、これらを制御するための制御回路、及びモーター等の部品が使われていて、特にモーター等の駆動力源(以下駆動エンジンと称す)はコスト的にも重量的にも大きな比重を占めている。 A solar elevation control device is used to receive sunlight at an optimal angle, and a heliostat is used to collect reflected light (hereinafter referred to as a solar tracking device). These include a servo mechanism and gimbal. Mechanisms, control circuits for controlling them, and parts such as motors are used. Especially, driving power sources such as motors (hereinafter referred to as drive engines) occupy a large specific cost and weight. ing.
このため、太陽電池や反射鏡よりも駆動エンジンのコストの方が高くなる、オーバーヘッド現象が生じ、太陽光利用の普及のネックとなっていた。 For this reason, the cost of the drive engine is higher than that of a solar cell or a reflecting mirror, resulting in an overhead phenomenon, which has become a bottleneck in the spread of sunlight.
最低限一個の駆動エンジンから駆動力を得て多数個の太陽光追尾装置を駆動させる事が出来れば、上記欠点は解消されるのであるが、従来に於いてはその様な発想は無く、一台の太陽光追尾装置に付き一個の駆動エンジンが使用されていた。 If the driving force can be obtained from at least one driving engine and a large number of solar tracking devices can be driven, the above disadvantages can be eliminated. However, there is no such idea in the past, and one A single drive engine was used for each solar tracker.
一対の駆動系で複数の反射鏡を動作させる方式のものとして、特許文献1があるが、これは、一対のクランク駆動部材から一対のクランク連結部材を介して複数の回動部材を動作させるものであり、これらの部材のコズト、重量は従来の欠点を解消するものではない。 As a method of operating a plurality of reflecting mirrors with a pair of drive systems, there is Patent Document 1, which operates a plurality of rotating members from a pair of crank drive members via a pair of crank connecting members. However, the damage and weight of these members do not eliminate the conventional drawbacks.
特願2001-248366Japanese Patent Application 2001-248366
本発明は上記したオーバーヘッドを解消して、少ない費用で且つ軽量で効率的に太陽光を集光する目的でなされた。 The present invention has been made for the purpose of eliminating the overhead described above and concentrating sunlight efficiently at a low cost and light weight.
駆動エンジンを太陽光追尾装置毎に装備するのではなく、外部に用意した最小限一個の駆動エンジンから得た回転力で自由雲台を駆動する。 Rather than equip each solar light tracking device with a drive engine, the free pan head is driven with the rotational force obtained from at least one externally prepared drive engine.
この外部駆動エンジンの回転軸が本発明の回転軸に結合され、この回転力でXY駆動軸を作動させて、制御信号にに応じて自由雲台を任意角度にする。この回転軸の両端は本発明同士を結合する事が可能なように結合端となっていて、これをカスケード式に多段連結する。つまり外部からの回転軸が、本発明を貫通して次段の本発明の回転軸と結合されるのである。 The rotational shaft of the external drive engine is coupled to the rotational shaft of the present invention, and the XY drive shaft is operated by this rotational force to make the free pan head an arbitrary angle according to the control signal. Both ends of the rotating shaft are coupled ends so that the present invention can be coupled to each other, and these are coupled in a cascade manner in a multistage manner. That is, the rotating shaft from the outside penetrates the present invention and is coupled to the rotating shaft of the present invention at the next stage.
そして上記した制御信号を送受信する信号線も、回転軸と同様にカスケード接続され、各本発明に配信されて自由雲台を任意角度に制御し、太陽の動きに追従して自由雲台に取付した太陽電池や反射鏡を刻々変化させる。 The signal lines for transmitting and receiving the control signals are also cascaded in the same manner as the rotating shaft, and are distributed to each invention to control the free pan head at an arbitrary angle, and follow the sun movement to attach to the free pan head. Change the solar cell and the reflecting mirror every moment.
多数個の太陽光追尾装置を制御する駆動力源たる駆動エンジンを最低限一個にする事が可能となり、メガソーラ施設に於いて最小コストで利用する事が出来る。また、ユニバーサルジョイント等で回転力を接続する事により整地されていない場所でも、メガソーラ施設が可能になる。また、システムを軽量化出来るので、一般家庭の屋根でも、太陽追従式ソーラー発電が可能になり、更に太陽光を集光して利用する太陽熱利用システムに適用する事が可能となるのである。 It is possible to use at least one driving engine as a driving force source for controlling a large number of solar tracking devices, and it can be used at a minimum cost in a mega solar facility. In addition, a mega solar facility is possible even in a place that is not leveled by connecting rotational force with a universal joint or the like. In addition, since the system can be reduced in weight, solar-following solar power generation is possible even on the roof of ordinary households, and further, it can be applied to a solar heat utilization system that collects and uses sunlight.

以下図を使い本発明の実施例について説明する。反射鏡Mを取付した自由雲台200は球状軸受け130によりXY軸に可動自在に支承されていて、制御信号線300から入力された制御情報に従って、XY軸駆動制御機構150により駆動されるX軸駆動桿162とY軸駆動桿164の動作に従い、任意角度に自在に変化する。 Embodiments of the present invention will be described below with reference to the drawings. The free pan head 200 to which the reflecting mirror M is attached is movably supported by the spherical bearing 130 on the XY axes, and is driven by the XY axis drive control mechanism 150 according to the control information input from the control signal line 300. According to the operation of the driving rod 162 and the Y-axis driving rod 164, it can be freely changed to an arbitrary angle.
XY軸駆動制御機構150への駆動力源は、筐体100を貫通する貫通回転軸140の回転力であり、この回転力がウォーム145を介してX軸入力歯車152及びY軸入力歯車154から入力される。 The driving force source to the XY axis drive control mechanism 150 is the rotational force of the through rotary shaft 140 that penetrates the housing 100, and this rotational force is transmitted from the X axis input gear 152 and the Y axis input gear 154 via the worm 145. Entered.
貫通回転軸140の一端は 回転入力結合端144であり、他端は 回転出力結合端146となっていて、図2に示す様に外部の駆動エンジンEの回転軸を回転入力結合端144に接続する。この回転力が自由雲台200を動作させる駆動源となるのであり、更にこの回転力を次段→次々段と多段数連結して回転力を伝達する。 One end of the through-rotating shaft 140 is a rotational input coupling end 144, and the other end is a rotational output coupling end 146, and the rotational shaft of an external drive engine E is connected to the rotational input coupling end 144 as shown in FIG. To do. This rotational force serves as a driving source for operating the free pan head 200, and this rotational force is connected in multiple stages from the next stage to the next stage to transmit the rotational force.
連結された次段の本発明は、前段と同様この回転軸から駆動力を得て、XY軸駆動制御機構150により自由雲台200が任意角度に動作するのであるが、この動作制御は制御機器Cから、制御信号線300を経由して配信される角度制御情報により制御される。この角度制御情報は多数個の本発明を一義的に識別するための識別番号と、当該本発明への制御角度情報から成り、これにより、カスケード結合された多数個の本発明の自由雲台200はそれぞれ個々に、任意な角度に制御されるのである。 In the present invention of the connected next stage, the driving force is obtained from the rotating shaft as in the previous stage, and the free pan head 200 is operated at an arbitrary angle by the XY axis drive control mechanism 150. C is controlled by angle control information distributed via the control signal line 300. This angle control information is composed of an identification number for uniquely identifying a large number of the present inventions and control angle information for the present invention, whereby a number of cascaded free pan heads 200 of the present invention are obtained. Are individually controlled at an arbitrary angle.
以上説明したように、外部の駆動エンジンEからの回転力を貫通回転軸140のウォームギヤを介して自由雲台200の駆動力として利用し、さらにこの回転を次段→次々段の貫通回転軸140に連続的に伝達する事により、駆動エンジンを内部に有する事無く、多数個の太陽電池又は反射鏡を自在角度に制御する事が可能となるのであり、この事が本発明の特徴である。 As described above, the rotational force from the external drive engine E is used as the driving force of the free pan head 200 via the worm gear of the through-rotating shaft 140, and this rotation is further passed from the next stage to the next-stage through rotating shaft 140. By continuously transmitting to the light source, it becomes possible to control a large number of solar cells or reflecting mirrors at an arbitrary angle without having a drive engine inside, which is a feature of the present invention.
図3は太陽電池Tを自由雲台200に取付した本発明を、高低差のある斜面等に於いてメガソーラー発電を行うシステムの実施例であり、一箇所の基地局から駆動力たる回転と制御情報を配給する例である。 FIG. 3 shows an embodiment of a system for performing mega solar power generation on a slope having a height difference, etc., in which the present invention in which a solar cell T is attached to a free pan head 200, and a rotation as a driving force from one base station. It is an example of distributing control information.
基地局には駆動エンジンEを有し、この回転力を各本発明にカスケード接続し供給する。この際、基地局と本発明との間に高低差があれば、ユニバーサルジョイントUを介して回転力軸を結合する。本発明には必要に応じて複数の回転出力端を有し、カスケード接続と共に、並列接続も可能にする。これによりマトリクス状に本発明を配置する事が可能になる。 The base station has a drive engine E, and this rotational force is cascaded and supplied to each invention. At this time, if there is a height difference between the base station and the present invention, the rotational force shaft is coupled via the universal joint U. The present invention has a plurality of rotation output ends as required, and enables parallel connection as well as cascade connection. As a result, the present invention can be arranged in a matrix.
基地局の制御機器Cは、各本発明の位置と現在の太陽の位置を勘案して、各本発明の自由雲台200が採るべき最適角度制御情報を御信号線300で送信する。この御信号線300も貫通回転軸140と同様、カスケード接続されている。 The control device C of the base station transmits the optimal angle control information to be taken by the free pan head 200 of the present invention through the control signal line 300 in consideration of the position of the present invention and the current position of the sun. The control signal line 300 is also cascade-connected like the penetrating rotary shaft 140.
そしてこれを受信した各本発明の自由雲台200はこれに従って角度を適切に変化させ 、これにより太陽電池Tの受光面は最適な太陽仰角を保持する事が可能になるのである。
また、太陽仰角の制御を、制御機器に頼らず、受光素子等で得た現在の受光量を基に独自に行ってもよい。
Then, the free pan / tilt head 200 of the present invention that has received this changes the angle appropriately according to this, whereby the light receiving surface of the solar cell T can maintain the optimum solar elevation angle.
Further, the control of the solar elevation angle may be performed independently based on the current received light amount obtained by the light receiving element or the like without depending on the control device.
図4は反射鏡Mを取り付けた自由雲台200を制御しての屋根に設置した集光器Cに集光して一般家庭で太陽光を利用するシステムの例で、各本発明の太陽仰角の制御を個々に有する受光素子400の受光量を基に行う例である。これは本発明が個々に駆動エンジンを有さない事による軽量で安価であると云う特徴により可能になるのである。 FIG. 4 shows an example of a system that uses sunlight in a general household by condensing on a condenser C installed on a roof controlled by a free pan head 200 to which a reflecting mirror M is attached. This is an example in which the control is performed based on the amount of light received by the light receiving element 400 having each control. This is made possible by the feature that the present invention is light and inexpensive because it does not have a drive engine individually.
