葉部３０は、板状体であり上からガラス板３２、太陽電池モジュール３１、境界板３４、裏板３３が積層されている。このうちのガラス板３２と複数の太陽電池モジュール３１により太陽電池パネルが形成される。また、裏板３３の前端と後端には棒状の装飾縁３８が固定される。また、ガラス板３２は装飾縁３８に固定される押さえ板３５により上から押さえられて固定されている。また、裏板３３には枝部２０の先端と回動自在に連結する枝部連結部３７が設けられて枝部２０の先端と連結している。太陽電池モジュール３１は枝部２０の内部を通る電線２４と連結している。さらに、裏板３３には複数の冷却水が出る穴である冷却水吐出口３３ａが設けられている。裏板と境界板３４との間には隙間３６が形成されており、枝部２０を通る冷却水パイプ２３の先端はこの隙間３６内に水を供給するようになっている。また裏板３３の外面側には凹凸を形成するために薄い布３３ｂが貼り付けられている。   The leaf portion 30 is a plate-like body, and a glass plate 32, a solar cell module 31, a boundary plate 34, and a back plate 33 are laminated from above. Of these, a glass panel 32 and a plurality of solar cell modules 31 form a solar cell panel. A bar-shaped decorative edge 38 is fixed to the front end and the rear end of the back plate 33. The glass plate 32 is pressed and fixed from above by a pressing plate 35 fixed to the decorative edge 38. Further, the back plate 33 is provided with a branch connecting portion 37 that is rotatably connected to the tip of the branch portion 20 and is connected to the tip of the branch portion 20. The solar cell module 31 is connected to an electric wire 24 that passes through the inside of the branch portion 20.

地下茎部４０は、幹部１０の下端と接続され、幹部１０と接続される箱状体４１と箱状体４１の４つの側面から側方に伸びるパイプ体４２、４３とにより形成される。地下茎部４０の内部には図示しない幹部１０内の冷却水パイプ１２ａと接続される冷却水を供給する冷却水管と、幹部１０内の電気ケーブル１３ａと接続される電気ケーブルが内側を通っている。また、箱状体４１内部には冷却水パイプ１２ａへの水の流れを制御する電磁バルブと制御装置が設けられている。冷却水管には水道水が常時供給されているがこの電磁バルブにより葉部３０への冷却水の供給は所定時のみに限定される。具体的には、制御装置は温度センサーに接続されており、気温が２０度以上になると電磁バルブを一定時間開くようになっている。開く時間は葉部３０の裏面に張られた布３３ｂが全体的に濡れる程度の時間である。このような動作を気温が２０度以上の場合に定期的に繰り返す。パイプ体４２内の電気ケーブルは図示しない二次電池に接続され、ここで葉部３０の太陽電池モジュールで発生した電気を溜めるようになっている。また、パイプ体４３は転倒防止のために設けられるパイプであって内部はふさがれており電気ケーブル等は通らない。
なお、太陽電池発電装置Ａは複数設けられる場合には地下茎部４０のパイプ体４２同士で接続される。これにより、大きな電力を得ることができるとともに転倒防止にも役立つことになる。
上記のような構成を有する太陽電池発電装置Ａは、幹部１０の枝部２０が設けられていない方向を北にして地下茎部４０を地面に埋めることで幹部１０を地面に立てて使用する。この際、温度が高くなると葉部３０の裏面が自動的に濡れて葉部３０の温度を下げるので、温度上昇によって発電効率が落ちることが抑えられる。 The underground stem 40 is connected to the lower end of the trunk 10, and is formed by a box-like body 41 connected to the trunk 10 and pipe bodies 42 and 43 extending laterally from four side surfaces of the box-like body 41. Inside the underground stem 40, a cooling water pipe for supplying cooling water connected to the cooling water pipe 12 a in the trunk 10 (not shown) and an electric cable connected to the electric cable 13 a in the trunk 10 pass inside. In addition, an electromagnetic valve and a control device for controlling the flow of water to the cooling water pipe 12a are provided inside the box-shaped body 41. Although the tap water is always supplied to the cooling water pipe, the supply of the cooling water to the leaf portion 30 is limited to a predetermined time by the electromagnetic valve. Specifically, the control device is connected to a temperature sensor, and opens the electromagnetic valve for a certain period of time when the temperature reaches 20 degrees or more. The opening time is such a time that the cloth 33b stretched on the back surface of the leaf portion 30 gets wet as a whole. Such an operation is periodically repeated when the temperature is 20 ° C. or higher. The electric cable in the pipe body 42 is connected to a secondary battery (not shown), and the electricity generated in the solar cell module of the leaf portion 30 is stored here. Further, the pipe body 43 is a pipe provided for preventing overturning, and the inside is blocked so that an electric cable or the like cannot pass therethrough.
When a plurality of solar battery power generation devices A are provided, the pipe bodies 42 of the underground stem 40 are connected to each other. As a result, a large amount of electric power can be obtained, and it can be useful for preventing overturning.
The solar cell power generation apparatus A having the above-described configuration uses the trunk 10 standing on the ground by burying the underground stem 40 in the ground with the direction in which the branch 20 of the trunk 10 is not provided being north. At this time, when the temperature is increased, the back surface of the leaf portion 30 is automatically wetted and the temperature of the leaf portion 30 is lowered, so that the power generation efficiency is prevented from being lowered due to the temperature rise.

（実施の形態２）
次に、本発明の実施の形態２に係る太陽電池発電装置Ｂについて説明する。太陽電池発電装置Ｂは太陽電池発電装置Ａとほぼ同様の構成であるが、葉部の裏面は冷却水吐出口が設けられる代わりに太陽電池パネルが設けられる点、一部の葉部は表面が鏡になっている点、冷却水は幹部の頂点から散水される点、幹部の全周にわたって枝部が設けられる点において相違する。

The solar cell modules 61 and 63 are connected to the electric wires 24 that pass through the branches 20. Here, since there is no cooling water discharge port, no cooling water pipe is provided in the branch portion 20.

図９に太陽電池発電装置Ｂの葉部のうち鏡を表面に設けた鏡面葉部７０および枝部２０の縦断面図を示す。鏡面葉部７０は板状体であり、枠体７２に鏡７１が嵌められ、枠体７２に固定される押さえ板７３により鏡７１は上から押さえられて固定されている。枠体７２の裏側には枝部２０の先端と回動自在に連結する枝部連結部７４が設けられて枝部２０の先端と連結している。なお、枝部２０内には電線も冷却パイプも設けられていない。

このような構成を有する太陽電池発電装置Ｂは、鏡面葉部７０を主に北側に位置させ、鏡面葉部７０に設けられる鏡により日光が他の裏面受光葉部６０の裏面に反射されるような角度を持たせる。これによって、裏面受光葉部６０は表面の太陽電池パネルによる発電のみならず、裏面の太陽電池パネルにより鏡面葉部７０からの光および地面の照り返しや散乱光を受けて発電を行うことができる。 FIG. 9 shows a vertical cross-sectional view of the mirror surface leaf portion 70 and the branch portion 20 provided with a mirror on the surface among the leaf portions of the solar battery power generation apparatus B. The mirror surface leaf portion 70 is a plate-like body, and a mirror 71 is fitted on the frame body 72, and the mirror 71 is pressed and fixed from above by a pressing plate 73 fixed to the frame body 72. On the back side of the frame body 72, a branch portion connecting portion 74 that is rotatably connected to the tip of the branch portion 20 is provided and connected to the tip of the branch portion 20. In addition, neither the electric wire nor the cooling pipe is provided in the branch part 20.
FIG. 10 shows a front view of the solar battery power generator B. The solar cell power generator B is provided with a watering nozzle 80 at the apex. In the solar battery power generation apparatus B, instead of supplying cooling water to each leaf portion, four water spray nozzles 80 at the apex are provided in the direction of each leaf portion. As with the solar battery power generation apparatus A according to the first embodiment, the water spray is periodically sprayed when the temperature of the cooling water reaches a certain temperature or more by the electromagnetic valve and the control device in the box-like body 41 of the underground stem 40. ing.
The solar battery power generation device B having such a configuration has the mirror surface leaf portion 70 mainly located on the north side so that sunlight is reflected on the back surface of the other back surface light receiving leaf portion 60 by the mirror provided on the mirror surface leaf portion 70. Give the right angle. Thus, the back light receiving leaf portion 60 can generate power not only by the power generation by the solar cell panel on the front surface but also by receiving the light from the mirror surface leaf portion 70 and the reflected or scattered light from the ground surface by the solar cell panel on the back surface.
