特開２００２−２６３５７号公報JP 2002-26357 A

本発明は、上記従来のものとは異なる構成で、採光調整と太陽光発電とを同時に行うことができる太陽光発電装置を提供することを目的としている。   An object of the present invention is to provide a photovoltaic power generation apparatus that can perform daylighting adjustment and photovoltaic power generation at the same time with a configuration different from that of the conventional one.

以下、添付図面の符号を参照して説明するが、本発明はこれに限定されるものではない。
上記課題を解決するための、本発明の太陽光発電装置１は、建物内の採光部分の直下に概略水平に設けられる矩形の支持枠２と、この支持枠２上に支架される少なくとも平行一対の支持レール３と、支持レール３と平行に、支持枠２に張られモータ駆動で延線方向に繰り出し繰り戻し自在の牽引ワイヤＷと、連結ロッド６により相互に間隔を置いて連結されると共に、牽引ワイヤＷに連結される複数の太陽電池パネル５とを具備する。支持枠２は、互いに平行に配置される前端辺２ａと後端辺２ｂ及びこれらと直交する左側辺２ｃと右側辺２ｄの４辺を具備する。支持レール３は、支持枠２上に、両側辺２ｃ，２ｄと平行に両端辺２ａ，２ｂ間に支架される。牽引ワイヤＷは、支持レール３と平行に、支持枠２に張られ、後端辺２ｂ側へ繰り出され、前端辺２ａ側へ繰り戻される。太陽電池パネル５は、それぞれ左右両側中央に前記支持レール上を転動可能なローラを具備し、連結ロッド６により相対回転自在に連結され、牽引ワイヤＷの繰り出し動作に連動して支持枠２内に相互間隔を置いて概略水平に展開し、牽引ワイヤＷの繰り戻し動作に連動して支持枠２内の前端辺２ａ側に概略垂直に折り重なって格納されるように、支持レール３に沿って移動自在である。 Hereinafter, the present invention will be described with reference to the accompanying drawings, but the present invention is not limited thereto.
In order to solve the above problems, a photovoltaic power generation apparatus 1 according to the present invention includes a rectangular support frame 2 provided substantially horizontally immediately below a daylighting portion in a building, and at least a parallel pair supported on the support frame 2. The support rail 3 and the support rail 3 are connected to each other by a connecting rod 6 at a distance from each other by a connecting rod 6 and a pulling wire W which is stretched on the support frame 2 in parallel with the support rail 3 and can be extended in the extending direction by motor drive. And a plurality of solar cell panels 5 connected to the pulling wire W. The support frame 2 includes four sides, a front end side 2a and a rear end side 2b that are arranged in parallel to each other, and a left side 2c and a right side 2d that are orthogonal to these. The support rail 3 is supported on the support frame 2 between both side edges 2a and 2b in parallel with both side edges 2c and 2d. The pulling wire W is stretched on the support frame 2 in parallel with the support rail 3, drawn out toward the rear end side 2 b, and fed back toward the front end side 2 a. Each of the solar cell panels 5 includes rollers that can roll on the support rails at the center of both the left and right sides, and are connected to each other by a connecting rod 6 so as to be relatively rotatable. Along the support rail 3 so as to be expanded substantially horizontally and spaced apart from each other, and folded and stored substantially vertically on the front end side 2a side in the support frame 2 in conjunction with the rewinding operation of the pulling wire W. It is movable.

本発明の太陽光発電装置１は、不使用時に、支持枠内の前端辺側に概略垂直に折り重なって格納される。モータを始動して牽引ワイヤＷ１を繰り出すと、支持枠の後端辺側の太陽電池パネルから順次、前端辺側の太陽電池パネルへと牽引ワイヤＷ１に引かれて同方向に転倒する。全てがほぼ水平に転倒した展開状態でモータが停止する。これにより、建物の採光部から入射する太陽光の多くを太陽電池パネルで遮蔽し、下方への入射を制限すると同時に、太陽電池パネルに受けた太陽光により発電を行うことができる。牽引ワイヤＷ１を繰り戻すと、支持枠の後端辺側の太陽電池パネルから順次、前端辺側の太陽電池パネルへと連結ロッドに押されて同方向に起立し、前端辺側へ集合する。全てがほぼ垂直に起立して重畳した格納状態でモータＭが停止する。   The solar power generation device 1 of the present invention is folded and stored substantially vertically on the front end side in the support frame when not in use. When the motor is started and the pulling wire W1 is fed out, the solar cell panel on the rear end side of the support frame is sequentially pulled to the solar cell panel on the front end side and falls in the same direction. The motor stops in the unfolded state where everything has fallen almost horizontally. Thereby, most of the sunlight incident from the daylighting part of the building is shielded by the solar cell panel, and the downward incidence is restricted, and at the same time, power generation can be performed by the sunlight received by the solar cell panel. When the pulling wire W1 is fed back, the solar cell panel on the rear end side of the support frame is sequentially pushed to the solar cell panel on the front end side by the connecting rod and rises in the same direction, and gathers on the front end side. The motor M stops in a retracted state in which everything stands up vertically and is superimposed.

図面を参照して本発明の実施の形態を説明する。
図１ないし図３において、太陽光発電装置１は、図示しない温室などの建物内の採光部分の直下に水平に設けられる支持枠２上に複数の太陽電池パネル５を前端側へ収束（図３）させたり、後端側へ展開させたり（図１，２）できるように設けてなる。建物が温室であれば、支持枠２の下方に植物が栽培される。 Embodiments of the present invention will be described with reference to the drawings.
1 to 3, the solar power generation device 1 converges a plurality of solar battery panels 5 on a support frame 2 provided horizontally below a daylighting part in a building (not shown) such as a greenhouse (see FIG. 3). ) Or deployed to the rear end side (FIGS. 1 and 2). If the building is a greenhouse, plants are grown below the support frame 2.

支持枠２は、アルミ型材等を矩形に組んでなり、互いに平行に配置される前端辺２ａと後端辺２ｂ及びこれらと直交する左側辺２ｃと右側辺２ｄの４辺を具備する。   The support frame 2 is formed by assembling an aluminum mold or the like into a rectangle, and includes a front end side 2a and a rear end side 2b arranged in parallel to each other, and a left side 2c and a right side 2d orthogonal to these.

アルミアングル材等からなる３本の支持レール３ａ，３ｂ，３ｃが、支持枠２の両側辺２ｃ、２ｄと平行に、両端辺２ａ，２ｂ間に支架される。   Three support rails 3 a, 3 b, 3 c made of an aluminum angle material or the like are supported between both side edges 2 a, 2 b in parallel with both side edges 2 c, 2 d of the support frame 2.

牽引ワイヤＷが、支持枠２の前端辺２ａと後端辺２ｂ上に設けられたスプロケット４間に掛け回される。牽引ワイヤＷは、前端辺２ａ側に設けられたモータＭにより、後端辺２ｂ側へ進む方向へ繰り出され、前端辺２ａ側へ進む方向へ繰り戻される。   The pulling wire W is hung between the sprockets 4 provided on the front end side 2a and the rear end side 2b of the support frame 2. The pulling wire W is drawn out in a direction to advance toward the rear end side 2b by a motor M provided on the front end side 2a, and is returned in a direction to advance toward the front end side 2a.

複数の太陽電池パネル５が、連結ロッド６により相互に間隔を置いて連結され、支持レール３上に移動自在に支持される。図示の実施形態において、太陽電池パネル５は、左右に２列設けられ、３本の支持レール３ａ，３ｂ，３ｃ上に支持されているが、１列の太陽電池パネル５を２本の支持レール上に支持する構成でもよい。太陽電池パネル５は、矩形板状のパネル本体７と、当該パネル本体７を支持レール３に移動自在に支持するローラ８とを具備する。   A plurality of solar battery panels 5 are connected to each other by connecting rods 6 at intervals, and are supported on the support rail 3 so as to be movable. In the illustrated embodiment, the solar cell panels 5 are provided in two rows on the left and right sides and are supported on three support rails 3a, 3b, 3c. The structure supported above may be sufficient. The solar cell panel 5 includes a rectangular plate-like panel body 7 and a roller 8 that supports the panel body 7 movably on the support rail 3.

図４、図５に示すように、パネル本体７は、可撓性の太陽電池積層シート９と、それの四囲を囲む４つの枠材１０ａ，１０ｂ，１０ｃ，１０ｄとを具備する。太陽電池積層シート９は、可撓性シート状基体９ａの表面側に可撓性太陽電池モジュール９ｂを積層してなる。太陽電池パネル５が支持枠２内に相互間隔を置いてほぼ水平に展開した状態において、前側枠材１０ａは支持枠２の前端辺２ａ側にこれと平行に、後側枠材１０ｂは支持枠の後端辺２ｂ側にこれと平行にそれぞれ配置され、太陽電池モジュール９ｂが積層された側の受光面が上方に向く。受光面の反対側が裏面となる。前側枠材１０ａのレール３ｂ側の端部には、当接片１１が、展開状態における前方へ延出するように取り付けられる。図６、図８に示すように、当接片１１が支持レール３の上面に当接することにより、太陽電池パネル５が、展開状態において、受光面を上に向け、わずかに前端辺２ａ側へ上昇する傾斜を持つように配置される。 As shown in FIGS. 4 and 5, the panel body 7 includes a flexible solar cell laminated sheet 9 and four frame members 10 a, 10 b, 10 c, and 10 d that surround the four surroundings. The solar cell laminate sheet 9 is formed by laminating a flexible solar cell module 9b on the surface side of a flexible sheet-like substrate 9a. In a state in which the solar cell panel 5 is deployed almost horizontally in the support frame 2 with a space between each other, the front frame member 10a is parallel to the front end side 2a side of the support frame 2, and the rear frame member 10b is the support frame. The light receiving surface on the side where the solar cell modules 9b are stacked faces upward, respectively, on the rear end side 2b side. The opposite side of the light receiving surface is the back surface. A contact piece 11 is attached to the end of the front frame member 10a on the rail 3b side so as to extend forward in the unfolded state. As shown in FIGS. 6 and 8, the contact piece 11 contacts the upper surface of the support rail 3, so that the solar cell panel 5 faces the front end side 2 a slightly in the unfolded state with the light receiving surface facing upward. Arranged to have a rising slope.

ローラ８は、パネル本体７の左側枠材１０ｃ、右側枠材１０ｄの側面の前後方向中央に軸８ａで取り付けられる。左右に並ぶ２つの太陽電池パネル５の一方のローラ８は、軸８ａで左右の両太陽電池パネル５に共通に支持され、中央の支持レール３ｂ上に乗っている。図９、図１１に示すように、前端の太陽電池パネル５のローラ８は、レール３に固定されたローラ保持金具１３に保持され、レール３上を移動できない。この太陽電池パネル５は、当該ローラ８の軸周りには回転自在である。   The roller 8 is attached to the center in the front-rear direction of the side surface of the left frame member 10c and the right frame member 10d of the panel body 7 by a shaft 8a. One roller 8 of the two solar cell panels 5 arranged on the left and right is supported by both the left and right solar cell panels 5 by a shaft 8a, and rides on a central support rail 3b. As shown in FIGS. 9 and 11, the roller 8 of the solar cell panel 5 at the front end is held by the roller holding bracket 13 fixed to the rail 3 and cannot move on the rail 3. The solar cell panel 5 is rotatable around the axis of the roller 8.

前後に隣接する太陽電池パネル５同士は、左側枠材１０ｃ又は右側枠材１０ｄの側面の前後端部において、連結ロッド６の両端に相対回転自在に連結される。図１０に示すように、牽引ワイヤＷは、もっとも後端辺２ｂ側に位置する太陽電池パネル５の左側枠材１０ｃの側面に止め金具１２で係止される。   The solar cell panels 5 adjacent to each other in the front-rear direction are connected to both ends of the connecting rod 6 so as to be relatively rotatable at front and rear end portions on the side surface of the left frame member 10c or the right frame member 10d. As shown in FIG. 10, the pulling wire W is locked to the side surface of the left frame member 10 c of the solar cell panel 5 located closest to the rear end side 2 b by the stopper 12.

したがって、太陽電池パネル５は、牽引ワイヤＷの繰り出し、繰り戻し動作に連動して支持レール３に沿って移動する。図３、図７に示すように格納状態にある太陽電池パネル５は、牽引ワイヤＷが繰り出されると、支持枠２内に相互間隔を置いて概略水平になるように展開し、牽引ワイヤＷの繰り戻されると、支持枠２内の前端辺２ａ側に集積し、概略垂直に折り重なって格納される。   Therefore, the solar cell panel 5 moves along the support rail 3 in conjunction with the pulling-out and pulling-out operations of the pulling wire W. As shown in FIGS. 3 and 7, when the pulling wire W is unwound, the solar battery panel 5 in the retracted state expands in the support frame 2 so as to be substantially horizontal with a mutual interval therebetween. When it is fed back, it accumulates on the front end side 2a side in the support frame 2 and is folded and stored substantially vertically.

太陽光発電装置１は、不使用時において、牽引ワイヤＷを繰り戻した状態で、支持枠２内の前端辺２ａ側に太陽電池パネル５が集積した格納状態（図３、図７）にある。この状態において、太陽電池パネル５は、交互に表裏を対面させて概略垂直に折り重なった状態にある。モータＭを起動して牽引ワイヤＷを繰り出すと、後端の太陽電池パネル５から順次、前端の太陽電池パネルへと、連結ロッド６を介して牽引ワイヤＷ１に引かれ、支持ローラ８の軸８ａを中心にして、図３、図７において時計方向へ回転しつつ、支持レール３上を後方へ移動する。全てがほぼ水平に転倒した展開状態（図１、図２）で、図１０に示すように、後端の太陽電池パネル５の支持ローラ８の軸８ａがリミットスイッチ１５を起動させ、モータＭが停止する。これにより、建物の採光部から入射する太陽光の多くを太陽電池パネル５で遮蔽し、下方への入射を制限すると同時に、太陽電池パネル５に受けた太陽光により発電を行うことができる。   When not in use, the solar power generation device 1 is in a retracted state (FIGS. 3 and 7) in which the solar cell panel 5 is integrated on the front end side 2a side in the support frame 2 with the pulling wire W being fed back. . In this state, the solar cell panel 5 is in a state of being folded substantially vertically with the front and back facing each other alternately. When the motor M is activated and the pulling wire W is fed out, the rear end solar cell panel 5 is sequentially pulled to the front end solar cell panel via the connecting rod 6 to the pulling wire W1, and the shaft 8a of the support roller 8 is pulled. 3 and 7 while moving in the clockwise direction in FIG. 3 and FIG. As shown in FIG. 10, the shaft 8a of the support roller 8 of the solar cell panel 5 at the rear end activates the limit switch 15 and the motor M Stop. Thereby, most of the sunlight incident from the daylighting part of the building is shielded by the solar cell panel 5 and the downward incidence is restricted, and at the same time, power generation can be performed by the sunlight received by the solar cell panel 5.

この状態から、牽引ワイヤＷを繰り戻すと、後端の太陽電池パネル５から順次、前端の太陽電池パネル５へと、連結ロッド６に押され、後端側が押し下げられ、前端側が押し上げられるように、図３、図６において反時計方向へ回転しつつ、支持レール３上を前方へ移動する。太陽電池パネル５の前端側の当接片１１が支持レール３ｂの上面に当接しているため、各太陽電池パネル５は、前端側が後端側よりわずかに上位にあり、かつ当接片１１により下方への回転が阻止されるため、確実に同方向へ回転して起立し、図３、図７に示すように、前端辺２ａ側へ集合する。全てがほぼ垂直に起立して重畳した格納状態で、図１１に示すように、最後部の太陽電池パネル５がリミットスイッチ１４を起動させ、モータＭが停止する。   From this state, when the pulling wire W is fed back, the connecting rod 6 sequentially pushes from the rear end solar cell panel 5 to the front end solar cell panel 5, the rear end side is pushed down, and the front end side is pushed up. 3 and FIG. 6, it moves forward on the support rail 3 while rotating counterclockwise. Since the contact piece 11 on the front end side of the solar cell panel 5 is in contact with the upper surface of the support rail 3 b, each solar cell panel 5 has a front end side slightly higher than the rear end side, and the contact piece 11 Since the downward rotation is prevented, it reliably stands up by rotating in the same direction, and gathers toward the front end side 2a as shown in FIGS. As shown in FIG. 11, the solar cell panel 5 at the rearmost part activates the limit switch 14 and the motor M stops in a retracted state in which everything stands upright and overlaps.
