Description
この発明は、例えばため池や貯水池、養魚池、湖沼、海などのように水で覆われた場所に設置して発電を行うための水上設置太陽光発電装置に関する。
The present invention relates to a water-based photovoltaic power generation device that is installed in a place covered with water, such as a pond, a reservoir, a fish pond, a lake, a sea, or the like, to generate power.
水上設置太陽光発電装置は、フロートの上に太陽光パネルの表面からなる傾斜した受光面を複数備えているが、これら受光面の水平方向の向きはすべて同じであった。つまり、下記特許文献１に開示されている水上設置太陽光発電装置１０１のように、複数の受光面１０２が平行に配設されており、これら受光面１０２の水平方向の向きを南に向けて設置される。言い換えれば、受光面１０２の方位角は、南を基準にした場合には０度またはそれに近い値であった（図４参照）。
The photovoltaic power generator installed on the water has a plurality of inclined light receiving surfaces consisting of the surface of a solar panel on the float, but the horizontal directions of these light receiving surfaces are all the same. In other words, a plurality of light receiving surfaces 102 are disposed in parallel, as in the case of a water-mounted solar power generation device 101 disclosed in Patent Document 1 below, and the horizontal direction of these light receiving surfaces 102 is directed south. Will be installed. In other words, the azimuth angle of the light receiving surface 102 was 0 degrees or a value close thereto when the south was used as a reference (see FIG. 4).
このような構成の水上設置太陽光発電装置１０１では、受光面１０２の背面側（方位角が１８０度である北側）から風を受けると、太陽光パネル１０３に大きな負荷がかかるので、フロート１０４の上で太陽光パネル１０３を固定する架台１０５には強度が必要である。
In the water-mounted solar power generation apparatus 101 having such a configuration, when a wind is received from the rear side of the light receiving surface 102 (the north side having an azimuth of 180 degrees), a large load is applied to the solar panel 103. The base 105 for fixing the solar panel 103 above must have strength.
このため、太陽光パネル１０３の背面が風を受け得る構造の架台１０５で支持した場合には、受光面１０２の傾斜方向を構成する太陽光パネル１０３の枚数は、安全を考慮して通常１枚とされていた。つまり、架台１０５に支持される太陽光パネル１０３は、傾斜方向と直交する方向には複数枚固定しても、傾斜方向には１枚であった。
For this reason, when the back surface of the solar panel 103 is supported by the pedestal 105 having a structure capable of receiving wind, the number of the solar panels 103 constituting the inclination direction of the light receiving surface 102 is usually one in consideration of safety. And it was. That is, even if a plurality of solar panels 103 supported by the gantry 105 are fixed in a direction orthogonal to the tilt direction, the number is one in the tilt direction.
また、フロート１０４に対しては少しでも多くの太陽光パネル１０３を備えたい要求があるため、受光面１０２は前述のように平行に複数配設されることになる。この場合でもフロート１０４の上には太陽光パネル１０３の設置や管理のために作業員が移動する通路１０６が必要である。この通路１０６は、フロート１０４の外側縁のほかに、内側においては受光面１０２同士の間に備えることになる。しかし、例えば図４に示した特許文献１の水上設置太陽光発電装置１０１のように、３列の受光面１０２を備えた場合には、内側に２本の通路１０６が必要となって、フロート１０４の上面における受光面１０２の割合が、通路１０６のぶん低くなってしまう。
要求 Also, since there is a demand to provide the float 104 with as many solar panels 103 as possible, a plurality of light receiving surfaces 102 are arranged in parallel as described above. Even in this case, a passage 106 through which a worker moves for installation and management of the solar panel 103 is required on the float 104. The passage 106 is provided between the light receiving surfaces 102 on the inside in addition to the outside edge of the float 104. However, for example, when three rows of light receiving surfaces 102 are provided, as in the case of a solar photovoltaic power generator 101 of Patent Document 1 shown in FIG. The ratio of the light receiving surface 102 on the upper surface of the passage 104 becomes lower than that of the passage 106.
この発明は、架台の強度負担を軽減するとともに、フロート上面の面積の利用効率を高めることを主な目的とする。
A main object of the present invention is to reduce the strength load on the gantry and increase the efficiency of use of the area of the upper surface of the float.
そのための手段は、太陽光パネルの表面からなる傾斜した受光面をフロートの上に備えた水上設置太陽光発電装置において、前記受光面を複数備え、前記受光面の水平方向の向きを違えて、一の前記受光面の背面側に他の前記受光面の背面側を向けることである。
Means for that, in a water-based solar power generation device provided with an inclined light receiving surface consisting of the surface of the solar panel on the float, provided with a plurality of the light receiving surface, different in the horizontal direction of the light receiving surface, That is, the back side of the other light receiving surface faces the back side of the one light receiving surface.
この構成では、一の受光面の背面側に吹きつけようとする風は、他の受光面が受けて一の受光面に大きな負荷がかかることを防止する。風を受けた受光面は、風圧によって下方へ押さえ付けられるが、フロートが水面に浮いた状態を保持する。また全ての受光面は光を受けて発電を行う。受光面の傾斜角を低めに設定することによって、特に太陽の高度が高い地域では発電ロスを抑制できる。
In this configuration, the wind trying to blow on the back side of one light receiving surface prevents another light receiving surface from receiving a large load on one light receiving surface. The light receiving surface receiving the wind is pressed downward by the wind pressure, but keeps the float floating on the water surface. All light receiving surfaces receive light and generate power. By setting the inclination angle of the light receiving surface to be low, power generation loss can be suppressed particularly in an area where the altitude of the sun is high.
この発明によれば、他の受光面は一の受光面に対して風除けとして作用するとともに、太陽光パネルやフロートが浮き上がらないようにする押さえつけ力を発揮する機能を有するので、太陽光パネルを支持する架台の強度について負担を軽減できる。このため、傾斜方向に複数枚の太陽光パネルを備えて受光面を構成することが可能となり、通路の本数を減らすことも可能になって、フロート上面の面積の利用効率を高めることができる。
According to the present invention, the other light-receiving surface acts as a wind shield for one light-receiving surface and has a function of exerting a pressing force to prevent the solar panel and the float from floating, so that the solar panel is supported. The load on the strength of the gantry can be reduced. Therefore, the light receiving surface can be configured by including a plurality of solar panels in the inclined direction, the number of passages can be reduced, and the use efficiency of the area of the upper surface of the float can be increased.
この発明を実施するための一形態を、以下図面を用いて説明する。

支持材２２の上端に固定される受け材２３は、下側支持材２２ａから上側支持材２２ｃまで一直線に延びている。受け材２３の傾斜角が受光面１５の傾斜角となる構造であるので、所望の傾斜角が得られるように、下側支持材２２ａと中間支持材２２ｂと上側支持材２２ｃの長さと基材２１に対する固定位置が設定される。太陽光パネル１４は受け材２３に対してボルトなどで固定される。
The receiving member 23 fixed to the upper end of the support member 22 extends straight from the lower support member 22a to the upper support member 22c. Since the inclination angle of the receiving member 23 is equal to the inclination angle of the light receiving surface 15, the length of the lower support member 22a, the intermediate support member 22b, and the upper support member 22c and the base material are adjusted so that a desired inclination angle is obtained. A fixed position with respect to 21 is set. The solar panel 14 is fixed to the receiving member 23 with bolts or the like.
受光面１５の傾斜角は、発電装置１１の設置地域や設置に際しての向き（方位角）などの条件に応じて適宜設定される。設置地域が例えば台湾のように太陽高度が高い地域であって、２つの受光面１５の方位角をそれぞれ南（南を基準とした場合０度）と北（南を基準とした場合１８０度）とする場合には、傾斜角は８度くらいに設定するとよい。
傾斜 The inclination angle of the light receiving surface 15 is appropriately set according to conditions such as an installation area of the power generation device 11 and an orientation (azimuth angle) at the time of installation. The installation area is an area where the solar altitude is high such as Taiwan, for example, and the azimuths of the two light receiving surfaces 15 are respectively south (0 degrees when the south is a reference) and north (180 degrees when the south is a reference). In this case, the inclination angle may be set to about 8 degrees.
このような構成の発電装置１１は、図３に示したように複数個連結された状態で水面に浮かべられて、一体のものとして水底に係留される。このとき、前述のように方位角を南と北に設定するので、発電装置１１は受光面１５を南と北に向けて設置される。連結された発電装置１１同士の間は、相対変位可能である。
(3) A plurality of the power generating devices 11 having such a configuration are floated on the water surface in a state of being connected as shown in FIG. At this time, since the azimuth is set to south and north as described above, the power generator 11 is installed with the light receiving surface 15 facing south and north. A relative displacement is possible between the connected power generators 11.
水上に設置された発電装置１１の２つの受光面１５は、太陽光を受けて太陽光パネル１４で発電する。南を向く受光面１５はもちろん北を向く受光面１５も程度の差はあるものの発電を行う。
２ The two light receiving surfaces 15 of the power generating device 11 installed on the water receive the sunlight and generate electricity by the solar panel 14. The light-receiving surface 15 facing north as well as the light-receiving surface 15 facing south generates power, albeit with some differences.
水面を東西方向に風が吹くと、フロート１２の上では太陽光パネル１４の下を風が通過する。南北方向に風が吹くと、風上側の受光面１５が受け止めて他方の受光面１５の背面側に風が吹き付けられることを防止し、受光面１５が煽られて浮き上がる方向の力が作用することを防ぐ。同時に、風上側の受光面１５は、風を受けることによって下方へ押さえられる。
When the wind blows in the east-west direction on the water surface, the wind passes below the solar panel 14 on the float 12. When the wind blows in the north-south direction, the light receiving surface 15 on the windward side catches and prevents the wind from being blown to the rear side of the other light receiving surface 15, and the force in the direction in which the light receiving surface 15 is lifted by the light receiving surface 15 is actuated. prevent. At the same time, the light receiving surface 15 on the windward side is pressed downward by receiving the wind.
特に、２つの受光面１５の水平方向の向きが互いに逆であるので、一方の受光面１５が背面側から風を受けることを防止する作用と、他方の受光面１５が風の力を下方への力に変換する作用を確実に実行できる。
In particular, since the horizontal directions of the two light receiving surfaces 15 are opposite to each other, the function of preventing one light receiving surface 15 from receiving wind from the back side and the other light receiving surface 15 reducing the force of the wind downward. The function of converting the force into the force can be surely executed.
このため、前述のように受光面１５の背面が風を受け得る構造の架台１３の場合でも、架台１３の強度を高く設定しなくてもよい。つまり、強度を得ることに対する負担を軽減でき、前述したようにアングル材で架台１３を構成するなど、構造の簡素化や軽量化も図れる。
Therefore, even in the case of the gantry 13 having a structure in which the back surface of the light receiving surface 15 can receive wind as described above, the gantry 13 does not need to be set to a high strength. That is, the burden on obtaining strength can be reduced, and the simplification and weight reduction of the structure can be achieved, for example, by configuring the gantry 13 with the angle material as described above.
また、２つの受光面１５には、それぞれ６枚ずつで合計１２枚の太陽光パネル１４を備えており、配線やメンテナンスなどの管理に利用される通路１６を３本備えている。
{Circle around (2)} The two light receiving surfaces 15 are provided with a total of 12 solar panels 14 each including six solar panels, and are provided with three passages 16 used for management such as wiring and maintenance.
これに対して、受光面の傾斜方向に複数枚の太陽光パネルを並べられなかった従来の水上設置太陽光発電装置１０１では、図４に示したように、フロート１０４と太陽光パネル１０３の大きさが図１の発電装置１１のフロート１２及び太陽光パネル１４と同じ場合に、３枚の太陽光パネル１０３で構成される受光面１０２が３列しか形成できなかった。つまり、１個のフロート１０４の上に設置できる太陽光パネル１０３の枚数は合計で９枚であった。
On the other hand, in the conventional water-mounted solar power generation apparatus 101 in which a plurality of solar panels cannot be arranged in the inclination direction of the light receiving surface, as shown in FIG. In this case, the light receiving surface 102 composed of the three solar panels 103 could be formed in only three rows when the float 12 and the solar panel 14 of the power generator 11 in FIG. 1 were used. That is, the total number of solar panels 103 that can be installed on one float 104 was nine.
しかし、前述のようにこの発明では１２枚の太陽光パネル１４を載置することができる。このため、フロート１２の上面の面積の利用効率を高めることができる。
However, as described above, in the present invention, twelve solar panels 14 can be mounted. Therefore, the utilization efficiency of the area of the upper surface of the float 12 can be improved.
以上はこの発明を実施するための一形態の構成であって、この発明は、前述の構成のみに限定されるものではなく、その他の構成を採用することができる。
The above is the configuration of one embodiment for carrying out the present invention, and the present invention is not limited to the above-described configuration, and other configurations can be adopted.
たとえば、フロートの大きさや平面視形状との関係で、前述のような２面で一対の受光面１５の他にも受光面を備えることができる。また、水平方向の向きが同一の複数の受光面を備えることもできる。水平方向の三方、又は四方などに向く受光面を備えることもできる。
For example, depending on the size of the float and the shape in plan view, a light receiving surface can be provided in addition to the pair of light receiving surfaces 15 as described above. Also, a plurality of light receiving surfaces having the same horizontal direction can be provided. It is also possible to provide a light receiving surface oriented in three directions or four directions in the horizontal direction.
受光面１５の傾斜方向に並べる太陽光パネル１４の枚数は１枚とするほか、３枚以上とすることも可能である。
(4) The number of solar panels 14 arranged in the inclination direction of the light receiving surface 15 may be one, or may be three or more.
また、一方に向く受光面を備えた複数のフロートを、受光面の水平方向の向きを違えて、一の受光面の背面側に他の受光面の背面側を向けた状態で結合一体化して発電装置１１を構成してもよい。
In addition, multiple floats with a light receiving surface facing one side are combined and integrated with the horizontal direction of the light receiving surface changed, with the back side of one light receiving surface facing the back side of the other light receiving surface The power generation device 11 may be configured.
