以下、本発明を図面に示す実施の形態に基づいて説明する。
〔本実施の形態の概要〕
本発明による太陽追尾機能付き架台の概要を図1に基づいて説明し、太陽追尾動作の概要を図2〜図5に基づいて説明する。
Hereinafter, the present invention will be described based on the embodiments shown in the drawings.
[Outline of the present embodiment]
The outline of the rack with the sun tracking function according to the present invention will be described based on FIG. 1, and the outline of the sun tracking operation will be described based on FIGS.

図1に示す架台300には、ソーラパネルユニット400が装備されて太陽光発電機100を構成する。架台300は、ソーラユニットパネル400を載置する架台本体310を3本の支持脚311、312、313により3点支持する構成としている。3本の支持脚の支持点を結ぶと、各支持点は三角形の各頂点に位置する。架台本体310を3本の支持脚311〜313で3点支持する構成は、架台300を水平面に限らず、傾斜面に設置する場合でも3本の支持脚311〜313が必ず当接するという特徴がある。また、3本の支持脚311〜313の長さが異なっても各支持脚311〜313は必ず当接する。その際、架台本体310は傾斜する。   A solar panel unit 400 is provided on the gantry 300 shown in FIG. The gantry 300 is configured to support a gantry main body 310 on which the solar unit panel 400 is placed at three points by three support legs 311, 312, and 313. When the support points of the three support legs are connected, each support point is located at each vertex of the triangle. The configuration in which the gantry body 310 is supported at three points by the three support legs 311 to 313 is characterized in that the three support legs 311 to 313 always come into contact with each other even when the gantry 300 is installed on an inclined surface. is there. Also, even if the lengths of the three support legs 311 to 313 are different, the support legs 311 to 313 always abut. At that time, the gantry body 310 is inclined.

3本の支持脚311〜313の長さが異なると、架台本体310は丈の長い支持脚を上側、丈の低い支持脚を下側として傾斜する傾斜面をなす。このことより、ある支持脚の丈を他の支持脚よりも短くすると、架台本体310の傾斜面を丈の短い支持脚側に向かわせることができる。   When the lengths of the three support legs 311 to 313 are different, the gantry body 310 forms an inclined surface that inclines with the longer support legs on the upper side and the lower support legs on the lower side. From this, when the length of one support leg is shorter than the other support legs, the inclined surface of the gantry body 310 can be directed to the shorter support leg side.

架台300の3本の支持脚311〜313について、支持脚の長さが温度上昇で短くなり、温度低下で長くなるという温度変化による長さ調節機能を備えたものとしている。架台本体310を遮光性の板材である遮光板とした場合、太陽の向きによって、3本の支持脚311〜313の丈に変化が生じる。例えば、太陽光が照射されて温度が上昇した支持脚は丈が短くなり、遮光板である架台本体310により太陽光が遮られて温度が低下した支持脚は丈が短くなる。そうすると、太陽に向いた支持脚は丈が短くなり、架台本体310は太陽に向かって傾斜することになる。   The three support legs 311 to 313 of the gantry 300 are provided with a length adjustment function due to a temperature change in which the length of the support legs is shortened by a temperature rise and becomes long by a temperature drop. When the gantry body 310 is a light-shielding plate that is a light-shielding plate material, the length of the three support legs 311 to 313 varies depending on the direction of the sun. For example, the length of the supporting legs whose temperature has risen by the irradiation of sunlight is shortened, and the length of the supporting legs whose temperature is lowered by blocking the sunlight by the gantry body 310 which is a light shielding plate are shortened. As a result, the length of the support legs facing the sun is shortened, and the gantry body 310 is inclined toward the sun.

3本の支持脚311〜313の上端が架台本体310の裏面にしっかりと固定されていると、3本の支持脚311〜313の丈の変化に応じて架台本体310の自由な傾動動作ができない。このため、3本の支持脚311〜313はそれぞれユニバーサルジョイント(自在継手)320を介して架台本体310に連結され、台1本体310の自由な傾動動作を確保している。架台300は、ユニバーサルジョイント320による架台本体310の自由な傾動を可能とすることにより、架台本体310を太陽の向きに傾斜させながら追尾させることができるようにしている。   If the upper ends of the three support legs 311 to 313 are firmly fixed to the back surface of the gantry body 310, the gantry body 310 cannot be freely tilted according to the change in the length of the three support legs 311 to 313. . For this reason, the three support legs 311 to 313 are connected to the gantry body 310 via the universal joints (universal joints) 320, respectively, and secure a free tilting operation of the base 1 body 310. The gantry 300 allows the gantry body 310 to be freely tilted by the universal joint 320, thereby allowing the gantry body 310 to be tracked while being tilted toward the sun.

図1において、架台300は、基台301にユニバーサルジョイント320を備えた3本の支持脚311〜313を取り付け、各ユニバーサルジョイント320を介して遮光板である架台本体310を3本の支持脚311〜313に連結している。架台本体310には、図1(b)に示すように、架台本体310の傾動動作を促進する複数の球体302を転動可能に収納する転球収納枠部303が設けられている。転球収納枠部303内における複数の球体302の偏り状態で架台本体310の傾斜方向が判断可能となる。   In FIG. 1, a gantry 300 has three support legs 311 to 313 provided with a universal joint 320 attached to a base 301, and a gantry body 310 that is a light shielding plate is connected to the three support legs 311 via the universal joints 320. To 313. As shown in FIG. 1B, the gantry main body 310 is provided with a rolling ball storage frame portion 303 that movably accommodates a plurality of spheres 302 that facilitate the tilting operation of the gantry main body 310. The tilt direction of the gantry body 310 can be determined by the biased state of the plurality of balls 302 in the ball rolling storage frame portion 303.

転球収納枠部303の上に、図1(c)に示すソーラパネルユニット400が取り付けられる。基台301の幅を2dとすると、基台301の前側で、幅方向中央に第1支持脚311、後側の両角部に第2支持脚312、第3支持脚313を取り付けており、第1支持脚311の取付位置を頂点とする二等辺三角形の底辺両端に第2支持脚312、第3支持脚313を取り付けた構成として以下に説明する。また、図2〜図5において、第1支持脚311を南側、第2支持脚312を東側、第3支持脚313を西側に向けるようにして太陽光発電機100を配置したものとする。さらに、第1支持脚311〜第3支持脚311は、同一温度において同一長さとして説明する。   A solar panel unit 400 shown in FIG. 1C is attached on the rolling ball storage frame 303. If the width of the base 301 is 2d, the first support leg 311 is attached to the front side of the base 301 at the center in the width direction, and the second support leg 312 and the third support leg 313 are attached to both corners on the rear side. In the following description, the second support leg 312 and the third support leg 313 are attached to both ends of the base of an isosceles triangle whose apex is the attachment position of the first support leg 311. 2 to 5, it is assumed that the solar power generator 100 is arranged such that the first support leg 311 faces the south side, the second support leg 312 faces the east side, and the third support leg 313 faces the west side. Further, the first support leg 311 to the third support leg 311 will be described as having the same length at the same temperature.

図2は太陽Sの向きが南東の場合を示し、図2(a)に示すように架台本体310上のソーラパネルユニット400は南東に向けて傾斜する。第1支持脚311と第2支持脚312と第3支持脚313について、架台本体310による日陰の影響が最も少ないのは第1支持脚311、最も大きいのは第3支持脚313、中間は第2支持脚312である。したがって、丈の長さは第1支持脚311、第2支持脚312、第3支持脚313の順に長くなる。   FIG. 2 shows a case where the direction of the sun S is southeast, and the solar panel unit 400 on the gantry body 310 is inclined toward the southeast as shown in FIG. Of the first support leg 311, the second support leg 312, and the third support leg 313, the first support leg 311 has the least influence of the shade by the gantry body 310, the largest is the third support leg 313, and the middle is the first support leg 313. 2 support legs 312. Therefore, the length of the length becomes longer in the order of the first support leg 311, the second support leg 312, and the third support leg 313.

図2(b)に示すように、複数の球体302は架台本体310の傾斜方向である南東方向に集まる。図2(c)に示すように、架台本体310の南側前端が低く、西側から東側に傾斜する。図2(d)に示すように、架台本体310の北側の後端は、南側前端よりも高く、西側から東方向に傾斜する。   As shown in FIG. 2 (b), the plurality of spheres 302 gather in the southeast direction, which is the inclination direction of the gantry body 310. As shown in FIG. 2C, the front end on the south side of the gantry body 310 is low and inclines from the west to the east. As shown in FIG. 2D, the rear end on the north side of the gantry body 310 is higher than the front end on the south side, and is inclined in the east direction from the west side.

図3は太陽Sの向きが真南(真上)の場合を示し、図3(a)に示すようにソーラパネルユニット400はフラットな状態に保持される。第1支持脚311と第2支持脚312と第3支持脚313に対する架台本体310による日陰の影響は同一になるので、第1支持脚311、第2支持脚312、第3支持脚313の丈は同一長さとなり、図3(c)及び図3(d)に示すように架台本体310はフラットになる。   FIG. 3 shows a case where the direction of the sun S is true south (directly above), and the solar panel unit 400 is held in a flat state as shown in FIG. Since the influence of the shade by the gantry body 310 on the first support leg 311, the second support leg 312, and the third support leg 313 is the same, the length of the first support leg 311, the second support leg 312, and the third support leg 313 is the same. Have the same length, and the gantry body 310 becomes flat as shown in FIGS. 3 (c) and 3 (d).

図4は太陽Sの向きが南西の場合を示し、図2(a)に示すように架台本体310上のソーラパネルユニット400は南西に向けて傾斜する。第1支持脚311と第2支持脚312と第3支持脚313について、架台本体310による日陰の影響が最も少ないのは第1支持脚311、最も大きいのは第2支持脚312、中間は第3支持脚313である。したがって、丈の長さは第1支持脚311、第3支持脚313、第2支持脚312の順に長くなる。   FIG. 4 shows the case where the direction of the sun S is southwest, and as shown in FIG. 2A, the solar panel unit 400 on the gantry body 310 is inclined toward the southwest. Of the first support leg 311, the second support leg 312, and the third support leg 313, the influence of the shade by the gantry body 310 is the least in the first support leg 311, the largest is the second support leg 312, and the middle is the first support leg 311. 3 support legs 313. Accordingly, the length of the length becomes longer in the order of the first support leg 311, the third support leg 313, and the second support leg 312.

図4(b)に示すように、複数の球体302は架台本体310の傾斜方向である南西方向に集まる。図4(c)に示すように、架台本体310の南側前端が低く、東側から西側に傾斜する。図4(d)に示すように、架台本体310の北側の後端は、南側前端よりも高く、東側から西方向に傾斜する。   As shown in FIG. 4 (b), the plurality of spheres 302 gather in the southwest direction which is the tilt direction of the gantry body 310. As shown in FIG. 4C, the front end on the south side of the gantry body 310 is low and inclines from the east to the west. As shown in FIG. 4D, the rear end on the north side of the gantry body 310 is higher than the front end on the south side and is inclined in the west direction from the east side.

太陽光発電機100は図5(a)のように屋根に設置し、又は図5(b)に示すように斜面等に設置することが一般的である。架台300を図5(a)に示す屋根に設置した場合を例にする。架台300を図5(e)、図5(f)のように東から西に向けて下り傾斜の屋根の傾斜面101に設置すると、ソーラパネルユニット400は東から西に向けて太陽Sを追尾する。日の入りから日の出前の間は、3本の支持脚311〜313は丈が等長なので、架台本体310とソーラパネルユニット400は傾斜面101と平行に保持される。太陽Sが東から南東方向に移動するに従って、第2支持脚312の温度上昇が最も大きく、次いで第1支持脚312、殆ど温度変化がないのが第3支持脚313となる。このため、架台本体310が東側を向くことになる。太陽Sの向きが南東方向まで移動すると、第1支持脚311の温度が第2支持脚312の温度を上回り、南側に面する第1支持脚311が第2支持脚312よりも丈が低くなり、架台本体310が南向きに傾斜することになる。図5(d)に示すように、架台本体310の傾斜に合わせて球体302は転球収納枠部303の南東寄りに集まる。   The solar power generator 100 is generally installed on the roof as shown in FIG. 5 (a), or installed on a slope or the like as shown in FIG. 5 (b). The case where the gantry 300 is installed on the roof shown in FIG. 5 (a) is taken as an example. When the gantry 300 is installed on the inclined surface 101 of the roof inclined downward from east to west as shown in FIGS. 5 (e) and 5 (f), the solar panel unit 400 tracks the sun S from east to west. Do. Since the three support legs 311 to 313 are equal in length from sunset to sunrise, the gantry body 310 and the solar panel unit 400 are held in parallel with the inclined surface 101. As the sun S moves from the east to the southeast, the temperature rise of the second support leg 312 is the largest, and then the first support leg 312, with almost no temperature change, is the third support leg 313. For this reason, the gantry body 310 faces the east side. When the direction of the sun S moves to the southeast direction, the temperature of the first support leg 311 exceeds the temperature of the second support leg 312, and the first support leg 311 facing the south side becomes lower than the second support leg 312. The gantry body 310 is inclined southward. As shown in FIG. 5 (d), the spheres 302 gather near the southeast of the rolling ball storage frame 303 in accordance with the inclination of the gantry body 310.

図1〜図5に基づく架台300の概要説明において、3本の支持脚311〜313は基台301上に当接させているが、基台301を設けずに、3本の支持脚311〜313を直接地面等に当接させるようにしてもよい。この場合、地面に凹凸があっても架台300はぐらつくことなく地面等に安定して据え付けられる。このため、架台300にソーラパネルユニット400を取り付けた太陽光発電機100は設置場所の状況に左右されることなく設置することができる。   Although the three support legs 311 to 313 are in contact with the base 301 in the outline explanation of the gantry 300 based on FIGS. 1 to 5, the three support legs 311 to 313 are not provided with the base 301. It may be made to abut 313 directly on the ground etc. In this case, the gantry 300 can be stably installed on the ground or the like without wobbling even if the ground is uneven. For this reason, the solar power generator 100 with the solar panel unit 400 attached to the gantry 300 can be installed without being affected by the situation of the installation location.

なお、第1支持脚311〜第3支持脚313の向きはこれに限定されるものではなく、架台300をどのような向きに設置しても、太陽に向いた支持脚側を低くなるように架台本体310が傾斜するので、太陽追尾が行われる。   Note that the orientation of the first support leg 311 to the third support leg 313 is not limited to this, and the support leg side facing the sun is lowered regardless of the orientation of the gantry 300. Since the gantry body 310 tilts, sun tracking is performed.

〔本実施の形態の構成〕
本発明による架台の概要説明に続き、以下に詳細な構成を説明する。
[Configuration of the present embodiment]
Following a brief description of the cradle according to the invention, the detailed configuration will be described below.

図6及び図7において、太陽光発電機1は、基台2に前記支持脚に相当する3基の支持装置10(以下、第1支持装置11、第2支持装置12、第3支持装置13とする)を取り付け、前記台本体に相当する遮光性を有する遮光板41を第1支持装置11、第2支持装置12、第3支持装置13により3点支持する。基台2と第1支持装置11と第2支持装置12と第3支持装置13と遮光板41により架台3を構成する。   In FIGS. 6 and 7, the solar power generator 1 includes three supporting devices 10 (hereinafter referred to as a first supporting device 11, a second supporting device 12, and a third supporting device 13) corresponding to the support legs on the base 2. And a light shielding plate 41 having a light shielding property corresponding to the base body is supported by the first support device 11, the second support device 12, and the third support device 13 at three points. The base 3, the first support device 11, the second support device 12, the third support device 13, and the light shielding plate 41 constitute a gantry 3.

本実施の形態では、ソーラパネルユニット40に遮光板41を設けており、架台3の天板をなす遮光板41にソーラパネルユニット40が取り付けられる。   In the present embodiment, the light shielding plate 41 is provided in the solar panel unit 40, and the solar panel unit 40 is attached to the light shielding plate 41 that forms the top plate of the gantry 3.

支持装置10は、太陽光の照射による温度変化により軸方向長さを変化させる支持高さ可変手段の構成部材として例えば帯状のバイメタルをコイル状に巻回して形成されたコイル状バイメタル21の温度変化に応じた長さ変化に基づき、遮光板41に対する支持点と基台2との上下方向距離であるの高さを調整する。コイル状バイメタル21が太陽光により温められると軸方向長さが伸び、温度が低下すると軸方向長さが短くなる特性を有する。   The supporting device 10 changes the temperature of the coiled bimetal 21 formed by, for example, winding a strip-like bimetal in a coil shape as a component of the support height varying means that changes the axial length by a temperature change due to sunlight irradiation. The height of the vertical distance between the support point for the light shielding plate 41 and the base 2 is adjusted based on the change in length according to. When the coiled bimetal 21 is warmed by sunlight, the axial length increases, and when the temperature decreases, the axial length decreases.

支持装置10は、支持高さ可変手段の後記する変換機構により、コイル状バイメタル21が昇温傾向にある、すなわち太陽の高度が高くなり、継続して温められる状況下において支持高さを低くするように動作する。逆に、コイル状バイメタル21が降温傾向にある、すなわち太陽の高度が低くなり、又は遮光されて温度が低下する状況下において支持高さを高くするように動作する。   The support device 10 lowers the support height under a situation in which the coiled bimetal 21 tends to rise in temperature, that is, when the altitude of the sun increases and is continuously heated, by a conversion mechanism described later on the support height varying means. To work. Conversely, the coiled bimetal 21 operates to increase the support height in a situation where the temperature tends to decrease, i.e., when the altitude of the sun decreases or the temperature decreases due to light shielding.

本実施の形態において、支持装置10は、矩形形状の基板22の一端部にコイル状バイメタル21を軸方向を上下方向にして下端を固定する。基板22の他端部には、円筒状の支持筒23を軸方向を上下方向にして下端を固定する。支持筒23内に支持部材である支持ロッド24が上下方向に移動自在に挿通される。支持ロッド24は、支持筒23の上端から上方にびるロッド上端には自在継手25が取り付けられ、自在継手25の取付軸26がソーラパネルユニット40の遮光性を有する遮光板41の裏面に取り付けられる。自在継手25は、回転ボール251に取付軸26が固定され、回転ボール251の回転中心Pを中心として取付軸26が支持ロッド24に対して任意の向きに移動自在となっている。したがって、ソーラパネルユニット40は回転中心Pを中心に任意の向きに傾斜可能となる。 In the present embodiment, the support device 10 fixes the lower end of the coil-shaped bimetal 21 to the one end of the rectangular substrate 22 with the axial direction in the vertical direction. The lower end of the cylindrical support cylinder 23 is fixed to the other end of the substrate 22 with the axial direction in the vertical direction. A support rod 24 as a support member is inserted into the support cylinder 23 so as to be movable in the vertical direction. Support rod 24, the universal joint 25 is attached to the extension building rod upper end upwardly from the upper end of the support tube 23, attached to the back surface of the light shielding plate 41 mounting shaft 26 of the universal joint 25 has a light-shielding property of the solar panel unit 40 It is done. In the universal joint 25, the mounting shaft 26 is fixed to the rotating ball 251, and the mounting shaft 26 is movable in an arbitrary direction with respect to the support rod 24 around the rotation center P of the rotating ball 251. Therefore, the solar panel unit 40 can be inclined in any direction around the rotation center P.

支持筒23内に配置される支持ロッド24の下端部には、連結ピン27が固定されており、作動レバー28の先端部に形成した軸方向に沿って細長い長孔29が連結ピン27に係合している。作動レバー28の先端部は、支持筒23の側面に上下方向に沿って形成した細い長孔で構成されたスリット30を通して支持筒23内に装入される。   A connection pin 27 is fixed to the lower end portion of the support rod 24 disposed in the support cylinder 23, and an elongated long hole 29 formed in the distal end portion of the operating lever 28 is engaged with the connection pin 27. Match. The distal end portion of the actuating lever 28 is inserted into the support cylinder 23 through a slit 30 formed by a narrow long hole formed in the side surface of the support cylinder 23 along the vertical direction.

作動レバー28の基端部は、コイル状バイメタル21の上端部に固定された連結軸31に連結ピン32を介して連結される。コイル状バイメタル21と支持筒23との間に起立して基板22に固定した支柱33の上端部に支軸34を介して作動レバー28が回転自在に取り付けられ、これらの部材等によってコイル状バイメタル21の伸縮動作を逆方向に変換する変換機構を構成する。   The base end portion of the operating lever 28 is connected to a connecting shaft 31 fixed to the upper end portion of the coiled bimetal 21 via a connecting pin 32. An actuating lever 28 is rotatably attached to the upper end portion of a support column 33 that is erected between the coiled bimetal 21 and the support cylinder 23 and fixed to the substrate 22 via a support shaft 34. The conversion mechanism which converts the expansion / contraction operation | movement of 21 to a reverse direction is comprised.

コイル状バイメタル21が可動範囲内で最長にびた状態で作動レバー28は支持ロッド24を下死点位置に下動させ、最も縮んだ状態で作動レバー28は支持ロッド24を上死点位置に上動させる。 In the operating lever 28 is Shin Vita state the longest in the coiled bimetal 21 is movable range is moved downward the support rod 24 to the bottom dead center position, the most contracted state actuating lever 28 is the top dead center position the support rod 24 Move up.

図7において、支持装置10は、コイル状バイメタル21が太陽光を浴びて熱くなると、コイル状バイメタル21の上端が矢印100方向に移動し、支持ロッド24が矢印200で示す下方に向けて下動し、取付軸26に取付けられたソーラパネルユニット40が下方に下がる。   In FIG. 7, when the coiled bimetal 21 is heated by being exposed to sunlight, the support device 10 moves the upper end of the coiled bimetal 21 in the direction of the arrow 100, and the support rod 24 moves downwards as indicated by the arrow 200. The solar panel unit 40 attached to the mounting shaft 26 is lowered downward.

基板22の裏面側には作動ロッド24の軸中心線上に回転支軸35が下方に向けて支出される。基台2の上面には、支持装置10の取り付け位置に回転支軸35が回転可能に係合する係合穴2aが形成されている。支持装置10は、基板22にコイル状バイメタル21と支柱33と支持筒23を固定してユニット化した構成としており、図6に示すように、回転支軸35を中心に時計回り方向(CW)及び反時計回り方向(CCW)に回転し、コイル状バイメタル21を任意の向きに向けることができる。   On the back surface side of the substrate 22, the rotary support shaft 35 is expended downward on the axial center line of the actuating rod 24. On the upper surface of the base 2, an engagement hole 2 a is formed in which the rotation support shaft 35 is rotatably engaged at a mounting position of the support device 10. The supporting device 10 has a configuration in which the coiled bimetal 21, the support 33, and the support cylinder 23 are fixed to the substrate 22 and unitized, and as shown in FIG. 6, clockwise direction (CW) around the rotation support shaft 35 And, it turns in the counterclockwise direction (CCW), and the coiled bimetal 21 can be oriented in any direction.

太陽光発電機1を設置する地域を北半球とすると、太陽は東から出て、南を通り西に沈むので、ソーラパネルユニット40を東側に向けて傾斜させ、徐々に南側に向け傾斜させ、さらに西側に向けて傾斜させることで、太陽光を効率よく受光することができる。また、ソーラパネルユニット40を3基の支持装置10で3点支持することは、3点の支持高さが異なってもソーラパネルユニットを傾斜状態で安定に支持できる。このため、第1支持装置11を南側、第2支持装置12を東側、第3支持装置13を西側に配置している。   If the area where the solar power generator 1 is installed is the northern hemisphere, the sun will exit from the east, pass through the south, and sink to the west, so that the solar panel unit 40 is inclined toward the east and gradually inclined toward the south. By inclining toward the west, sunlight can be efficiently received. Further, supporting the solar panel unit 40 at three points by the three support devices 10 can stably support the solar panel unit in an inclined state even if the support heights at the three points are different. Therefore, the first support device 11 is disposed on the south side, the second support device 12 on the east side, and the third support device 13 on the west side.

ここで、図7に示すように支持装置10の作動ロッド24の中心軸線Lが基台2の表面に交わる点を支持点Rとすると、図6に示すように、第1支持装置11の支持点をR1、第2支持装置12の支持点をR2、第3支持装置13の支持点をR3とする。支持点R1、R2、R3を結ぶ三角形を鋭角三角形とし、本実施の形態では二等辺三角形として支持点R1を頂点とすると、底辺の両端をR2とR3としている。各取付軸26と遮光板41との取付位置の関係においても前記二等辺三角形と同じ二等辺三角形が形成され、支持点とすることができる。   Here, assuming that the point where the central axis L of the operating rod 24 of the support device 10 intersects the surface of the base 2 as shown in FIG. 7 is a support point R, the support of the first support device 11 is shown in FIG. The point is R1, the support point of the second support device 12 is R2, and the support point of the third support device 13 is R3. The triangle connecting the support points R1, R2, and R3 is an acute triangle. In this embodiment, if the support point R1 is the apex as an isosceles triangle, both ends of the base are R2 and R3. An isosceles triangle that is the same as the isosceles triangle is also formed in the relationship between the mounting positions of the mounting shafts 26 and the light shielding plate 41, and can be used as a support point.

このように、鋭角三角形の各頂点で、南方向及び東西方向に第1支持装置11〜第3支持装置13を配置することにより、太陽が真上に位置する場合を除き、第1支持装置11〜第3支持装置13に対する太陽光の照射状態を異ならせることができ、日の出から日の入りに渡って確実に太陽の追尾が行える。   As described above, by arranging the first support device 11 to the third support device 13 in the south direction and the east-west direction at each vertex of the acute triangle, the first support device 11 is removed except when the sun is positioned directly above. The irradiation state of sunlight with respect to the third support device 13 can be varied, and the sun can be reliably tracked from sunrise to sunset.

図6〜図8に示すように、ソーラパネルユニット40は、ソーラパネル取付板43に複数のソーラパネル44が取り付けられた構成としている。架台3は、例えば正方形に形成された遮光板41の上面中央に、平面正方形の転球収納枠部42が取り付けられた構成とし、転球収納枠部42の開口上面を外形が正方形のソーラパネル取付板43で覆っている。転球収納枠部42と遮光板41とソーラパネル取付板43により囲まれた空間を転球収納部45とし、転球収納部45内に多数個の球体46が転がり自在に収納されている。球体46は鉄等の高比重の材料で形成され、導電性を備えている。   As shown in FIGS. 6 to 8, the solar panel unit 40 has a configuration in which a plurality of solar panels 44 are attached to a solar panel attachment plate 43. The gantry 3 has a configuration in which, for example, a square-shaped rolling ball storage frame portion 42 is attached to the center of the upper surface of a light shielding plate 41 formed in a square shape. Covered with a mounting plate 43. A space surrounded by the rolling ball storage frame portion 42, the light shielding plate 41, and the solar panel mounting plate 43 is defined as a rolling ball storage portion 45, and a large number of spheres 46 are stored in the rolling ball storage portion 45 in a freely rolling manner. The sphere 46 is formed of a high specific gravity material such as iron and has conductivity.

遮光板41の各辺は転球収納枠部45よりも外方にそれぞれ幅Wだけ延出されており、この延出部分は第1支持装置11と第2支持装置12と第3支持装置13のコイル状バイメタル21に対して日光を遮る庇として機能する。   Each side of the light shielding plate 41 is extended outward by a width W from the rolling ball storage frame portion 45, and the extended portions correspond to the first support device 11, the second support device 12, and the third support device 13. It functions as a cage that blocks sunlight from the coiled bimetal 21.

第1支持装置11の支持点R1は、遮光板41の東西方向に沿った長さの中央位置で、幅Wの前記延出部分の中央位置としている。第2支持装置12の支持点R2と第3支持装置13の支持点R3は、遮光板41の北側の側辺から延出幅Wの半分の位置で、それぞれ東及び西側の側辺から延出幅Wの半分の位置としている。なお、支持点R1は東側又は西側に偏ってもよく、支持点R2と支持点R3は南北方向においてずれてもよい。   The support point R1 of the first support device 11 is the center position of the length along the east-west direction of the light shielding plate 41, and is the center position of the extending portion with the width W. The support point R2 of the second support device 12 and the support point R3 of the third support device 13 extend from the sides on the east and west sides, respectively, at half the extension width W from the side on the north side of the light shielding plate 41 The position is half the width W. The support point R1 may be deviated toward the east side or the west side, and the support point R2 and the support point R3 may be shifted in the north-south direction.

図8に示すように、遮光板41の中央部分には転球収納枠部42内において、球面形状の凹部47が形成されており、凹部47の中央部分における深さを球体46が僅かにはまり込む程度としている。また、凹部47内に全ての球体46を収納可能とする。ソーラパネルユニット40が水平状態の場合、殆どの球体46が凹部47内に収納され、遮光板41と一体にソーラパネルユニット40が傾斜すると、傾斜方向に向けて移動する。その際、多数の重い球体46が傾斜方向に移動するので、ソーラパネルユニット40の傾斜側の重量を増加させて傾斜動作を加速させる。   As shown in FIG. 8, a spherical recess 47 is formed in the central portion of the light shielding plate 41 in the rolling ball storage frame portion 42, and the sphere 46 slightly fits the depth of the central portion of the recess 47. It is about to be included. In addition, all the spheres 46 can be stored in the recesses 47. When the solar panel unit 40 is in a horizontal state, most of the spheres 46 are accommodated in the recesses 47, and when the solar panel unit 40 is tilted integrally with the light shielding plate 41, the solar panel unit 40 moves in the tilting direction. At that time, since a number of heavy spheres 46 move in the tilt direction, the weight of the solar panel unit 40 on the tilt side is increased to accelerate the tilt operation.

転球収納枠部42は、東側に面する東枠板421と、南側に面する南枠板422と、西側に面する西枠板423と、北側に面する北枠板424とにより構成している。東枠板421の南北方向両端部内面側には、端面から僅かな距離を隔てて導電性の第1電極板48と第2電極板49が設けられている。同様に南枠板422の東西方向両端部内面側に導電性の第3電極板50と第4電極板51が設けられ、西枠板423の南北方向両端部内面側に導電性の第5電極板52と第6電極板53、北枠板424の東西方向両端部内面側に導電性の第7電極板54と第8電極板55が設けられている。   The rolling ball storage frame portion 42 includes an east frame plate 421 facing the east side, a south frame plate 422 facing the south side, a west frame plate 423 facing the west side, and a north frame plate 424 facing the north side. ing. A conductive first electrode plate 48 and a second electrode plate 49 are provided on the inner surface side of both end portions of the east frame plate 421 at a slight distance from the end surface. Similarly, a conductive third electrode plate 50 and a fourth electrode plate 51 are provided on the inner surfaces of both ends of the south frame plate 422 in the east-west direction, and a conductive fifth electrode is formed on the inner surfaces of both ends of the west frame plate 423 in the north-south direction. A conductive seventh electrode plate 54 and an eighth electrode plate 55 are provided on the inner surfaces of both ends of the plate 52, the sixth electrode plate 53, and the north frame plate 424 in the east-west direction.

転球収納枠部42の各角部に設けられる一対の第1電極板48と第8電極板55により第1スイッチS1、一対の第2電極板49と第3電極板50により第2スイッチS2、一対の第4電極板51と第5電極板52により第3スイッチS3、一対の第6電極板53と第7電極板54により第4スイッチS4を構成する。第1スイッチS1〜第4スイッチS4において、導電性を備えた球体46がスイッチ作動体として機能し、各一対の電極に球体46が接触して導通すると、スイッチオン(ON)の「1」信号、球体46が非接触の非導通状態でスイッチオフ(OFF)の「0」信号をソーラパネルユニット40の傾斜方位を示す図4(a)に示すソーラパネルユニット40の移動を確認する確認手段としてのインジケータに出力する。   A first switch S1 is provided by a pair of first electrode plates 48 and an eighth electrode plate 55 provided at each corner of the ball storage frame portion 42, and a second switch S2 is provided by a pair of second electrode plates 49 and a third electrode plate 50. The pair of fourth electrode plate 51 and the fifth electrode plate 52 constitute a third switch S3, and the pair of sixth electrode plate 53 and the seventh electrode plate 54 constitute a fourth switch S4. In the first switch S1 to the fourth switch S4, when the ball 46 having conductivity functions as a switch operating body and the ball 46 is brought into contact with each pair of electrodes and becomes conductive, the switch 1 (ON) "1" signal As a confirmation means for confirming the movement of the solar panel unit 40 shown in FIG. 4 (a), which indicates the inclination direction of the solar panel unit 40, when the sphere 46 is in a non-contact non-conducting state, and a “0” signal is turned off. To the indicator.

図9に示すインジケータ60は、基台2を水平配置した場合を例にするもので、東、南、西の向きにソーラパネルユニット40が傾斜した状態と、特別な設定の場合に太陽が真上に位置する状態をそれぞれ点灯表示で示す東表示部61、南表示部62、西表示部63、真上表示部64を有している。各表示部61〜64は、点灯回路65により点灯制御される。点灯回路65は、第1〜第4AND回路66〜69を有する。第1AND回路66には第1スイッチS1と第2スイッチS2から「0」又は「1」の信号が入力される。第2AND回路67には第2スイッチS2と第3スイッチS3から「0」又は「1」の信号が入力される。第3AND回路68には第3スイッチS3と第4スイッチS4から「0」又は「1」の信号が入力される。第4AND回路69には第1スイッチS1〜第4スイッチS4から「0」又は「1」の信号がそれぞれNOT回路70を介して入力される。   The indicator 60 shown in FIG. 9 is an example in which the base 2 is horizontally arranged. The solar panel unit 40 is inclined in the east, south, and west directions, and the sun is true in a special setting. It has an east display section 61, a south display section 62, a west display section 63, and a directly above display section 64, each of which is indicated by a lighting display. The lighting circuits 65 control lighting of the display units 61 to 64. The lighting circuit 65 includes first to fourth AND circuits 66 to 69. A signal of “0” or “1” is input to the first AND circuit 66 from the first switch S1 and the second switch S2. A signal “0” or “1” is input to the second AND circuit 67 from the second switch S2 and the third switch S3. The third AND circuit 68 receives “0” or “1” signals from the third switch S3 and the fourth switch S4. The fourth AND circuit 69 receives “0” or “1” signals from the first switch S1 to the fourth switch S4 via the NOT circuit 70, respectively.

第1スイッチS1と第2スイッチS2が共にオンとなりそれぞれ信号1が第1AND回路66に出力されると東表示部61が点灯する。第2スイッチS2と第3スイッチS3が共にオンとなりそれぞれ信号1が第2AND回路67に出力されると南表示部62が点灯する。第3スイッチS3と第4スイッチS4が共にオンとなりそれぞれ信号1が第3AND回路68に出力されると西表示部63が点灯する。   When both the first switch S1 and the second switch S2 are turned on and the signal 1 is output to the first AND circuit 66, the east display unit 61 is lit. When both the second switch S2 and the third switch S3 are turned on and the signal 1 is output to the second AND circuit 67, the south display unit 62 is lit. When both the third switch S3 and the fourth switch S4 are turned on and the signal 1 is output to the third AND circuit 68, the west display portion 63 is lit.

後記するが基台2を水平配置し、第2支持装置12と第3支持装置13を回転支軸35を中心に回転して東西方向に向け、各コイル状バイメタル21を遮光板41よりも外側に張り出した場合において、太陽が真南に来た時、第1スイッチS1〜第4スイッチS4が全てオフとなり、それぞれ信号0が各NOT回路70に出力され、各NOT回路70から信号1が第4AND回路69に出力されると真上表示部64が点灯する。   Although the post 2 will be described later, the base 2 is arranged horizontally, and the second support device 12 and the third support device 13 are rotated around the rotation support shaft 35 to turn east and west, and each coiled bimetal 21 is outside the light shielding plate 41 When the sun comes south, the first switch S1 to the fourth switch S4 are all turned off, the signal 0 is output to each NOT circuit 70, and the signal 1 is output from each NOT circuit 70. When the signal is output to the 4 AND circuit 69, the display unit 64 directly above lights up.

図6に示す実施の形態は、説明を容易とするために基台2を水平状態としているが、通常は家屋の傾斜した屋根に設置し、また傾斜した地面に基台2を傾斜して設置する。基台2を設けずに第1支持装置11〜第3支持装置13を直接設置個所の設置面に設置するようにしてもよい。例えば凹凸のある地面では基台2を使用すると太陽光発電装置1の姿勢安定性が悪くなるが、第1支持装置11〜第3支持装置13による3点支持で太陽光発電機1の姿勢安定性が確保できる。   Although the embodiment shown in FIG. 6 makes the base 2 horizontal for ease of explanation, the base 2 is usually installed on the inclined roof of a house, and the base 2 is installed on the inclined ground with the base 2 inclined. Do. The first support device 11 to the third support device 13 may be installed directly on the installation surface of the installation site without providing the base 2. For example, if the base 2 is used on uneven ground, the stability of the posture of the solar power generator 1 is deteriorated, but the posture of the solar power generator 1 is stabilized by three-point support by the first support device 11 to the third support device 13. It is possible to secure

太陽光発電機1を設置する地域を東京とすると、太陽が真南に来た時の太陽の高度(南中高度)は、冬至では31.6度、夏至では78.4度である。したがって、ソーラパネルユニット40の傾斜角度は夏場に比べて冬場を大きくすることが望ましい。また、緯度が低くなるに従って南中高度が高くなるので、設置地域の緯度が低くなるに従って基台2の傾斜角度を低くするのが好ましい。   Assuming that the area where the solar power generator 1 is installed is Tokyo, the altitude of the sun (south altitude) when the sun comes to the south is 31.6 degrees in the winter solstice and 78.4 degrees in the summer solstice. Therefore, it is desirable that the inclination angle of the solar panel unit 40 be larger in the winter than in the summer. Moreover, since the south-middle altitude increases as the latitude decreases, it is preferable to decrease the inclination angle of the base 2 as the latitude of the installation area decreases.

〔本実施の形態の動作〕
次に、太陽の向きに応じた太陽光発電機1のソーラパネルユニット40の動きを図10A〜図10Fに基づいて説明する。太陽光発電機1は、基台2を水平状態に設置し、第1支持装置11を南に向け、第1支持装置11よりも北側において第2支持装置12を東側、第3支持装置13を西側に配置したものとする。また、図10A〜図10Fにおいて、第1支持装置11のコイル状バイメタルに符号21Aを付し、第2支持装置12のコイル状バイメタルに符号21Bを付し、第3支持装置13のコイル状バイメタルを符号21Cを付して説明する。さらに、回転ボール25に固定の取付軸26は、第1支持装置11では符号26Aを付し、第2支持装置12では符号26Bを付し、第3支持装置13では符号26Cを付して説明する。
[Operation of the present embodiment]
Next, the movement of the solar panel unit 40 of the solar power generator 1 according to the direction of the sun will be described based on FIGS. 10A to 10F. The solar power generator 1 has the base 2 installed in a horizontal state, the first support device 11 faces south, the second support device 12 on the east side and the third support device 13 on the north side of the first support device 11. It shall be arranged on the west side. 10A to 10F, the coiled bimetal of the first support device 11 is denoted by reference numeral 21A, the coiled bimetal of the second support device 12 is denoted by reference numeral 21B, and the coiled bimetal of the third support device 13 is illustrated. Will be described with reference 21C. Further, the mounting shaft 26 fixed to the rotating ball 25 is denoted by reference numeral 26A in the first supporting device 11, denoted by reference numeral 26B in the second supporting device 12, and denoted by reference numeral 26C in the third supporting device 13. To do.

図10Aの(a)は、日の出によって東側から太陽光が太陽光発電機1に向けて当たっている状況を示す。第1支持装置11のコイル状バイメタル21Aと第2支持装置12のコイル状バイメタル21Bは東側面で略全長にわたって太陽光を浴びるため、略同温度に熱せられて軸方向に沿って略等長びる。したがって、各支持ロッド24は各作動レバー28を介して下方に押し下げられる。しかし、第3支持装置13のコイル状バイメタル21Cはソーラパネルユニット40により太陽光が遮られるため熱せられず、軸方向に沿った伸縮はない。 (A) of FIG. 10A shows a state where sunlight is directed to the solar power generator 1 from the east side by sunrise. For coiled bimetallic 21B of the coiled bimetallic 21A of the first support unit 11 and the second supporting device 12 is exposure to sunlight over substantially the entire length in the east side, a substantially equal Shin Cho along the axial direction substantially been heated to the same temperature I'm sorry. Thus, each support rod 24 is pushed downward via each actuating lever 28. However, the coiled bimetal 21C of the third support device 13 is not heated because the sunlight is blocked by the solar panel unit 40, and there is no expansion or contraction along the axial direction.

したがって、第3支持装置13の支持ロッド24の昇降動作はなく、第1支持装置11の支持ロッド24及び第2支持装置12の支持ロッド24の高さよりも第3支持装置13の支持ロッド24が高い位置にある。   Therefore, the supporting rod 24 of the third supporting device 13 is higher than the height of the supporting rod 24 of the first supporting device 11 and the supporting rod 24 of the second supporting device 12 without raising and lowering movement of the supporting rod 24 of the third supporting device 13. It is in a high position.

このような状態において、図10A(b)(c)に示すように、遮光板41の北西の角が最も高い位置に存在する格好で遮光板41が傾斜する。第1支持装置11の支持ロッド24と第2支持装置12の支持ロッド24は東西方向及び南北方向の位置が異なるため、遮光板41は南東の角を最も下げた状態で傾斜する。遮光板41が傾斜状態に保持されるのは、遮光板41を3点支持する取付軸26A、26B、26Cが自在継手25の各回転ボール251により任意の方向に向きが変えられることによる。   In such a state, as shown in FIGS. 10A (b) and 10 (c), the light shielding plate 41 is inclined so that the northwest corner of the light shielding plate 41 is present at the highest position. Since the support rods 24 of the first support device 11 and the support rods 24 of the second support device 12 are different in the positions in the east-west direction and the north-south direction, the light shielding plate 41 is inclined with the south-east corner lowered most. The reason why the light shielding plate 41 is held in an inclined state is that the mounting shafts 26 </ b> A, 26 </ b> B, 26 </ b> C that support the light shielding plate 41 at three points are changed in direction by the rotating balls 251 of the universal joint 25.

したがって、ソーラパネルユニット40のソーラパネル44は、東側に向けて傾斜するため、朝の太陽光を効率よく受光することができる。日の出から時間が経過すると、太陽の向きは南側に移動する。第1支持装置11のコイル状バイメタル21Aは遮光板41の幅Wの飛び出た部分(以下、庇とする)よりも南側に張り出ているため、太陽光が遮られることがない。これに対し、第2支持装置12のコイル状バイメタル21B及び第3支持装置13のコイル状バイメタル21Cは、日の出と日の入りを除けば遮光板41の庇により部分的に太陽光が遮られる。   Therefore, since the solar panel 44 of the solar panel unit 40 is inclined toward the east side, morning sunlight can be received efficiently. As time passes from sunrise, the direction of the sun moves to the south. The coiled bimetal 21A of the first support device 11 projects to the south of the protruding portion (hereinafter referred to as a weir) of the width W of the light shielding plate 41, so that sunlight is not blocked. On the other hand, the coiled bimetal 21 </ b> B of the second support device 12 and the coiled bimetal 21 </ b> C of the third support device 13 are partially blocked by sunlight of the light shielding plate 41 except for sunrise and sunset.

第2支持装置12のコイル状バイメタル21Bは太陽が南東から南に向うに従って、遮光板41の庇により徐々に太陽光の受光面積が減少して温度低下を招くため、第1支持装置11のコイル状バイメタル21Aが伸び、逆にコイル状バイメタル21Bが縮む。その結果、第1支持装置11の支持ロッド24の高さに比べて第2支持装置12の支持ロッド24の高さが高くなる。なお、第3支持装置13のコイル状バイメタル21Cは西側に配置され、遮光板41の庇により太陽光が遮られているため温度変化がない。したがって、第3支持装置13の支持ロッド24が最も高い。つまり、支持ロッド24は第1支持装置11が最も短く、次に第2支持装置12が長い。   The coiled bimetal 21B of the second support device 12 has a light receiving area that gradually decreases due to the light of the light shielding plate 41 as the sun goes from southeast to south, and thus the temperature of the first support device 11 decreases. The bimetal 21A extends, and conversely, the coiled bimetal 21B shrinks. As a result, the height of the support rod 24 of the second support device 12 is higher than the height of the support rod 24 of the first support device 11. The coiled bimetal 21 </ b> C of the third support device 13 is arranged on the west side, and sunlight is blocked by the ridges of the light shielding plate 41, so that there is no temperature change. Therefore, the support rod 24 of the third support device 13 is the highest. That is, the support rod 24 is the shortest in the first support device 11 and the second in the second support device 12 next.

このため、遮光板41は、依然北西の角を最高点としつつ、北東の角から南側への傾斜を大きくしながら第1支持装置11の取付軸26Aを支点として西側に向けてひねられるように傾斜する。したがって、太陽光の向きに追従してソーラパネルユニット40のソーラパネル44が向くことになる。   For this reason, the light-shielding plate 41 is twisted toward the west with the mounting shaft 26A of the first support device 11 as a fulcrum while increasing the inclination from the northeast corner to the south side, with the northwest corner still being the highest point. Incline. Accordingly, the solar panel 44 of the solar panel unit 40 follows the direction of sunlight.

すなわち、第1支持装置11の支持ロッド24の先端部に設けられている取付軸26を支軸として、ソーラパネルユニット40は、南北方向の傾動と東西方向に傾動する。そして、南北方向の傾動と東西方向の傾動を行う傾動力は、午前中では東側に配置した第2支持装置12が主として受け持ち、午後は西側に配置した第3支持装置13が主として受け持つことになる。   That is, the solar panel unit 40 tilts in the north-south direction and in the east-west direction with the mounting shaft 26 provided at the tip of the support rod 24 of the first support device 11 as a support shaft. And, in the morning, the second support device 12 arranged on the east side will mainly receive the tilting power that performs the north-south direction tilt and the east-west direction tilt, and in the afternoon, the third support device 13 set on the west side will mainly receive .

第1支持装置11と第2支持装置12と第3支持装置13のこのような動作の理解に基づき、以下図10Bでは太陽の向きが南西の場合、図10Cでは太陽の向きが南、図10Dでは太陽の向きが南西、図10Eでは太陽の向きが西の場合におけるソーラパネルユニット40の傾斜動作を説明する。   Based on the understanding of such operations of the first support device 11, the second support device 12, and the third support device 13, hereinafter, in FIG. 10B, the sun direction is southwest, in FIG. 10C, the sun direction is south, FIG. Now, the tilting operation of the solar panel unit 40 when the direction of the sun is southwest and FIG. 10E is the direction of the sun will be described.

図10Bの(a)に示すように太陽が南東に向いている場合、図10Aの状態に続いて第2支持装置12のコイル状バイメタル21Bは遮光板41の庇により太陽光が遮られて更なる受光面積の減少を招き、温度が低くなってさらに縮む。このため、第2支持装置12の支持ロッド24が長くなってソーラパネルユニット40の南側を下向きにしつつ遮光板41の南東の角を最も低くして傾斜し、図10Aの状態よりもより一層傾斜が大きくなる。したがって、ソーラパネル44は南東に向くと共に太陽の高度に合わせてソーラパネル44の受光面を大きく傾斜させる。   When the sun is facing southeast as shown in FIG. 10B (a), the coiled bimetal 21B of the second support device 12 is blocked by the light of the light shielding plate 41 following the state of FIG. The light receiving area is reduced, and the temperature is further reduced. For this reason, the support rod 24 of the second support device 12 becomes long and the south side of the solar panel unit 40 faces downward, and the southeast corner of the light-shielding plate 41 is inclined to the lowest, further inclined than the state of FIG. 10A. Becomes larger. Therefore, the solar panel 44 is directed to the southeast and inclines the light receiving surface of the solar panel 44 largely according to the altitude of the sun.

図10Cの(a)に示すように太陽が真南に向いている場合、第2支持装置12のコイル状バイメタル21Bと第3支持装置13のコイル状バイメタル21Cは遮光板41の庇により同じ遮光条件で太陽光が遮られるため、軸方向に同じ長さとなる。ただし、第1支持装置11のコイル状バイメタル21Aよりも高さが低い状態にある。すなわち、第1支持装置11の支持ロッド24が最も短く、第2支持装置12と第3支持装置13の各支持ロッド24が等しい長さとなる。したがって、図10C(b)及び(c)に示すように、ソーラパネルユニット40は南側を下向きにすると共に、遮光板41の南側辺を水平にして傾斜する。この傾斜角度は冬場に設定されており、第2支持装置12と第3支持装置13の各支持ロッド24をできるだけ高くし南向き傾斜を大きくしている。   As shown in FIG. 10C, when the sun is facing south, the coiled bimetal 21 </ b> B of the second support device 12 and the coiled bimetal 21 </ b> C of the third support device 13 are shielded by the light shield plate 41. Since sunlight is blocked under certain conditions, the length is the same in the axial direction. However, the height is lower than the coiled bimetal 21 </ b> A of the first support device 11. That is, the support rod 24 of the first support device 11 is the shortest, and the support rods 24 of the second support device 12 and the third support device 13 have the same length. Therefore, as shown in FIG. 10C (b) and (c), the solar panel unit 40 is inclined with the south side downward and the south side of the light shielding plate 41 horizontal. This inclination angle is set in winter, and the support rods 24 of the second support device 12 and the third support device 13 are made as high as possible to increase the southward inclination.

これに対し、第2支持装置12と第3支持装置13を支持点Q2、Q3を中心にして外側方向に張り出し、遮光板41の庇による遮光面積を少なくすると、コイル状バイメタル21Bとコイル状バイメタル21Cの温度が高くなって軸方向に沿ってびる。このため、第2支持装置12と第3支持装置13の支持ロッド24の高さが低くなり、ソーラパネル44の傾斜面が小さくなる。 On the other hand, when the second support device 12 and the third support device 13 are extended outward around the support points Q2 and Q3 to reduce the light blocking area by the wedge of the light blocking plate 41, the coiled bimetal 21B and the coiled bimetal Shin along the axial temperature of 21C becomes high buildings. For this reason, the heights of the support rods 24 of the second support device 12 and the third support device 13 are reduced, and the inclined surface of the solar panel 44 is reduced.

これにより、冬場は図1に示すように第2支持装置12と第3支持装置13を南北方向に沿って配置し、夏場は第2支持装置12のコイル状バイメタル21Bと第3支持装置13のコイル状バイメタル21Cを遮光板41の側縁から外側に張り出すように調整する。   Thereby, as shown in FIG. 1 in winter, the second support device 12 and the third support device 13 are arranged along the north-south direction, and in summer, the coiled bimetal 21B of the second support device 12 and the third support device 13 The coiled bimetal 21 </ b> C is adjusted so as to project outward from the side edge of the light shielding plate 41.

図10Dの(a)に示すように、太陽が南西に向いている場合、図10Bの(a)に示す太陽が南東に向いている場合とは逆に、図10Dの(b)(c)に示すように、第3支持装置13のコイル状バイメタル21Cが太陽光を浴びて軸方向に沿ってび、第2支持装置12のコイル状バイメタル21Bに対してはソーラパネルユニット40により太陽光が遮られて温度が低下して軸方向に沿って縮む。 As shown to (a) of FIG. 10D, when the sun is facing southwest, (b) and (c) of FIG. 10D contrary to the case where the sun shown to (a) of FIG. 10B is facing southeast. as shown in, Shin and coiled bimetallic 21C of the third support device 13 along the axial direction bathed in sunlight beauty, sunlight by a solar panel unit 40 for coiled bimetallic 21B of the second support device 12 And the temperature drops and shrinks along the axial direction.

したがって、第1支持装置11の支持ロッド24が最も短く、第2支持装置12の支持ロッド24が最も高く、第3支持装置13の支持ロッド24が中間の高さとなる。これにより、遮光板41は南西の角を最も低くし、南西の角に向けて傾斜し、ソーラパネルユニット40のソーラパネル44が太陽の方向である南西方向に向くことになる。   Therefore, the support rod 24 of the first support device 11 is the shortest, the support rod 24 of the second support device 12 is the highest, and the support rod 24 of the third support device 13 is at the middle height. Thereby, the light shielding plate 41 makes the southwest corner the lowest, inclines toward the southwest corner, and the solar panel 44 of the solar panel unit 40 faces the southwest direction which is the direction of the sun.

図10Eの(a)に示すように、太陽が西に向いている場合、図10Aの(a)に示す太陽が東に向いている場合とは逆に、第1支持装置11のコイル状バイメタル21Aと第3支持装置13のコイル状バイメタル21Cの太陽光受光面積が略等しいため、遮光板41の南西端の角を最も低くし、かつ遮光板41の北西端の角を図10Dの場合よりも一層低くし、遮光板41の西側辺を下向きにして傾斜する。したがって、ソーラパネル44が太陽の方向である西側に傾斜して向くことになる。   As shown in (a) of FIG. 10E, when the sun is facing west, the coiled bimetal of the first support device 11 is reverse to the case where the sun shown in (a) of FIG. 10A is facing east. Since the sunlight receiving area of the coiled bimetal 21C of the third support device 13 is substantially equal to that of 21A, the angle of the southwest end of the light shielding plate 41 is made the lowest, and the angle of the northwest end of the light shielding plate 41 is greater than in the case of FIG. And the west side of the light shielding plate 41 is inclined downward. Therefore, the solar panel 44 is inclined to the west side in the direction of the sun.

図10Fの(a)は、太陽光発電機1を赤道直下等の低緯度地域に設置した場合を示す。この場合、基台2を水平配置し、第2支持装置12と第3支持装置13を回転支軸35を中心に回転して東西方向に向け、各コイル状バイメタル21B、21Cを遮光板41よりも外側に張り出した構成としている。   (A) of FIG. 10F shows the case where the solar power generator 1 is installed in a low latitude area such as immediately below the equator. In this case, the base 2 is arranged horizontally, and the second support device 12 and the third support device 13 are rotated about the rotation support shaft 35 to face in the east-west direction, and the coiled bimetals 21B and 21C are shielded from the light shielding plate 41. It also has a configuration projecting outward.

この場合、太陽が東から上り、ある程度の高度に達すると、第1支持装置11〜第3支持装置13の各コイル状バイメタル21A、21B、21Cは略同じ条件で太陽光を受光するため、太陽光が真上を通過して西に向かい、ある程度の高度までの間において、図10Fの(b)(c)に示すように、各支持ロッド24は同じ高さを維持し、遮光板41は水平状態を維持して遮光パネル44は真上を向く。   In this case, when the sun rises from the east and reaches a certain height, the coiled bimetals 21A, 21B, and 21C of the first support device 11 to the third support device 13 receive sunlight under substantially the same conditions. As shown in (b) and (c) of FIG. 10F, the light maintains the same height, and the light shielding plate 41 is the same. The light shielding panel 44 faces directly upward while maintaining a horizontal state.

図11は図8及び図9に示す第1スイッチS1〜第4スイッチS4のスイッチング動作を説明する図である。   FIG. 11 is a diagram for explaining the switching operation of the first switch S1 to the fourth switch S4 shown in FIGS.

図11(a)はソーラパネルユニット40が東向きに傾斜している状態を示し、図10Aに対応する。この場合、転球収納部45内に収納される多数の球体46は、北東の角から南西の角近くまでの直角三角形で囲まれる領域に密集する。この場合、球体46の数を適宜調整することにより、第3スイッチS3には触れない。したがって、第1スイッチS1と第2スイッチS2が球体46によりオンとされ、第1スイッチS1と第2スイッチS2は信号1を出力する。   FIG. 11A shows a state in which the solar panel unit 40 is inclined to the east, and corresponds to FIG. 10A. In this case, the large number of spheres 46 stored in the rolling ball storage unit 45 are densely packed in a region surrounded by a right triangle from the northeast corner to the vicinity of the southwest corner. In this case, the third switch S3 is not touched by adjusting the number of the spheres 46 appropriately. Accordingly, the first switch S1 and the second switch S2 are turned on by the sphere 46, and the first switch S1 and the second switch S2 output the signal 1.

図11(b)はソーラパネルユニット40が南東向きに傾斜している状態を示し、図10Bに対応する。この場合、転球収納部45内に収納される多数の球体46は、図11(a)の場合よりも南向き傾斜が強くなり、遮光板41の東辺が少し西側に向けて傾斜するため、全体的に南側に移動し、転球収納部45の南北方向の略半部分を埋める。この場合、第1スイッチS1からは球体46が外れオフとなり、第2スイッチS2と第3スイッチS3が球体46によりオンとなる。   FIG. 11 (b) shows a state in which the solar panel unit 40 is inclined in the south-east direction, corresponding to FIG. 10B. In this case, the large number of spheres 46 stored in the rolling ball storage unit 45 are more inclined toward the south than in the case of FIG. 11A, and the east side of the light shielding plate 41 is slightly inclined toward the west side. It moves to the south side as a whole, and fills the almost half of the rolling ball storage portion 45 in the north-south direction. In this case, the sphere 46 is removed from the first switch S1 and turned off, and the second switch S2 and the third switch S3 are turned on by the sphere 46.

図11(c)はソーラパネルユニット40が南向きに傾斜している状態を示し、図10Cに対応する。この場合、転球収納部45内に収納される多数の球体46は、図11(c)の場合と同様に転球収納部45の南北方向の略半部分を埋める。この場合、第2スイッチS2と第3スイッチS3が球体46によりオンとなり、第2スイッチS2と第3スイッチS3は信号1を出力する。   FIG. 11C shows a state in which the solar panel unit 40 is inclined to the south, and corresponds to FIG. 10C. In this case, the large number of spheres 46 accommodated in the rolling ball storage unit 45 fill substantially half of the rolling ball storage unit 45 in the north-south direction as in the case of FIG. In this case, the second switch S2 and the third switch S3 are turned on by the sphere 46, and the second switch S2 and the third switch S3 output the signal 1.

図11(d)はソーラパネルユニット40が南西向きに傾斜している状態を示し、図10Dに対応する。この場合、転球収納部45内に収納される多数の球体46は、図11(b)の場合と東西方向で対称となり、第4スイッチS4がオフとなり、第2スイッチS2と第3スイッチS3が球体46によりオンとなる。   FIG. 11 (d) shows a state where the solar panel unit 40 is inclined southwestward, and corresponds to FIG. 10D. In this case, the large number of spheres 46 stored in the rolling ball storage unit 45 are symmetrical in the east-west direction as in the case of FIG. 11B, the fourth switch S4 is turned off, and the second switch S2 and the third switch S3. Is turned on by the sphere 46.

図11(e)はソーラパネルユニット40が西向きに傾斜している状態を示し、図10Eに対応する。この場合、転球収納部45内に収納される多数の球体46は、図11(a)の場合と東西方向で対称となり、第3スイッチS3と第4スイッチS4が球体46によりオンとなり、第3スイッチS3と第4スイッチS4は信号1を出力する。   FIG. 11 (e) shows a state where the solar panel unit 40 is inclined to the west, and corresponds to FIG. 10E. In this case, the large number of spheres 46 stored in the rolling ball storage unit 45 are symmetrical in the east-west direction with the case of FIG. 11A, the third switch S3 and the fourth switch S4 are turned on by the sphere 46, The 3-switch S3 and the fourth switch S4 output a signal 1.

図11(f)は図10Fに対応し、全ての球体46は凹部47内に入っている状態を示す。したがって、第1スイッチS1〜第4スイッチS4は全てオフとなり、各第1スイッチS1〜第4スイッチS4から信号0を出力する。   FIG. 11 (f) corresponds to FIG. 10F, showing that all the spheres 46 are in the recess 47. Therefore, the first switch S1 to the fourth switch S4 are all turned off, and the signal 0 is output from each of the first switch S1 to the fourth switch S4.

したがって、ソーラパネルユニット40が東向きに傾斜した場合には、図9に示す点灯回路65の第1AND回路66から信号1が出力されてインジケータ60の東表示部61が点灯する。同様に、ソーラパネルユニット40が南向きに傾斜した場合には、点灯回路65の第2AND回路67から信号1が出力されて南表示部62が点灯する。ソーラパネルユニット40が西向きに傾斜した場合には、第3AND回路68から信号1が出力されて西表示部61が点灯する。   Therefore, when the solar panel unit 40 is tilted eastward, the signal 1 is output from the first AND circuit 66 of the lighting circuit 65 shown in FIG. 9, and the east display portion 61 of the indicator 60 is lit. Similarly, when the solar panel unit 40 tilts southward, the signal 1 is output from the second AND circuit 67 of the lighting circuit 65 and the south display unit 62 is lit. When the solar panel unit 40 is tilted west, the signal 1 is output from the third AND circuit 68 and the west display unit 61 is lit.

また、ソーラパネルユニット40が真上を向いた場合には、第4AND回路69から信号1が出力されて真上表示部64が点灯する。   Further, when the solar panel unit 40 faces directly upward, the signal 1 is output from the fourth AND circuit 69 and the directly above display section 64 is lit.

〔本実施の形態の効果〕
以上説明したように本実施の形態の架台3によれば、3基の支持装置11〜13の支持ロッド24の昇降動作だけで、太陽の向きと高度に合わせて遮光板41を追尾させることができる。このため、従来のようなパン駆動系とチルト駆動系が不要となり、シンプルな構成の架台3を提供でき、また軽量化することができ、電源のない場所でも設置することができる。
[Effect of this embodiment]
As described above, according to the gantry 3 of the present embodiment, the shading plate 41 can be tracked in accordance with the sun's direction and altitude only by the lifting and lowering operation of the support rods 24 of the three support devices 11 to 13. it can. For this reason, the conventional pan driving system and tilt driving system are not required, and the gantry 3 having a simple configuration can be provided, the weight can be reduced, and the apparatus can be installed even in a place without a power source.

太陽光発電機1は、架台3を北半球の地域に設置する場合、3本の支持ロッド24の相対的な高さの差を利用してソーラパネルユニット40を太陽の向きに合わせて移動させる所謂パン動作と、ソーラパネルユニット40の南向き傾斜を維持し、太陽の高度が最も高い時に南向き傾斜角度を最も小さく(ソーラパネルユニット40を寝かせる)、その前後では南向き傾斜角度を大きく(ソーラパネルユニット40を立たせる)という所謂チルト動作を行うことができる。   When installing the gantry 3 in the northern hemisphere area, the solar power generator 1 uses the difference in relative heights of the three support rods 24 to move the solar panel unit 40 in accordance with the direction of the sun. The panning operation and the south-facing inclination of the solar panel unit 40 are maintained, the south-facing inclination angle is minimized when the solar altitude is the highest (the solar panel unit 40 is laid down), and the south-facing inclination angle is increased before and after (solar panel). It is possible to perform a so-called tilt operation of raising the panel unit 40).

つまり、日の出から日の入りの間で、南側に配置した第1支持装置11の支持ロッド24の高さが第2支持装置12と第3支持装置13の各支持ロッド24の高さよりも常に低くなってソーラパネルユニット40が南向きに傾斜する。   That is, between the sunrise and sunset, the height of the support rod 24 of the first support device 11 disposed on the south side is always lower than the height of the support rods 24 of the second support device 12 and the third support device 13. The solar panel unit 40 inclines to the south.

午前中は東側に配置した第2支持装置12のコイル状バイメタル21Bに当たる太陽光が徐々に遮られて第2支持装置12の支持ロッド24が徐々に高くなる。ただし、第3支持装置13のコイル状バイメタル21Cはソーラパネルユニット40により太陽光が遮られ、第3支持装置13の支持ロッド24の高さが最も高い。   In the morning, the sunlight hitting the coiled bimetal 21B of the second support device 12 disposed on the east side is gradually blocked, and the support rods 24 of the second support device 12 are gradually raised. However, the coiled bimetal 21 </ b> C of the third support device 13 is shielded from sunlight by the solar panel unit 40, and the height of the support rod 24 of the third support device 13 is the highest.

このため、太陽の向きが東から南に向けて移動するに従って第2支持装置12の支持ロッド24が上昇し、第1支持装置11の自在継手25の回転ボール251を支点としてソーラパネルユニット40が東側から西側に向けて徐々に回転し、東側から南に向けて移動するパン動作が行われる。   Therefore, the support rod 24 of the second support device 12 ascends as the direction of the sun moves from the east to the south, and the solar panel unit 40 takes the rotating ball 251 of the universal joint 25 of the first support device 11 as a fulcrum. A panning operation is carried out, which gradually rotates from the east side to the west side and moves from the east side to the south.

さらに、午後では午前とは逆に第3支持装置13のコイル状バイメタル21Cに対して太陽光が徐々に照射され、コイル状バイメタル21Cの温度が徐々に高くなって軸方向に沿ってびる。このため、第3支持装置13の支持ロッド24が徐々に低くなり、第1支持装置11の自在継手25の回転ボール251を支点としてソーラパネルユニット40がさらに西側に向けて徐々に回転し、南から西側に向けて移動するパン動作が行われる。 Furthermore, the sunlight gradually emitted to the coiled bimetallic 21C of the third support device 13 opposite to the morning afternoon, Shin along axially temperature of the coiled bimetallic 21C is gradually increased building. For this reason, the support rod 24 of the third support device 13 gradually lowers, and the solar panel unit 40 gradually rotates further toward the west side with the rotating ball 251 of the universal joint 25 of the first support device 11 as a fulcrum. Pan movement is performed moving from the west to the west.

〔変形例〕
なお、上記実施の形態において、架台3にソーラパネルユニット40を取り付けて太陽光発電機1を構成しているが、これに限らず、例えば、次の構成を採用することもできる。
[Modification]
In addition, in the said embodiment, although the solar panel unit 40 is attached to the mount frame 3 and the solar power generator 1 is comprised, not only this but the following structures are also employable, for example.

第1の構成は、太陽を追尾して乾燥効率を高める構成であり、乾物材料(例えば、魚や海苔等の水産物、野菜や果実等の農産物)、食塩の原料となる海水、洗濯物、生ゴミ等の廃棄物その他の被乾燥体を架台3の遮光板41に設置する。例えば、干物や海苔は、網やすのこに乗せ、これを架台3の遮光板41に設置する。   The first configuration is to improve the drying efficiency by tracking the sun, such as dry matter materials (for example, marine products such as fish and seaweed, agricultural products such as vegetables and fruits), seawater used as a raw material for salt, laundry, and garbage. Etc. are placed on the light shielding plate 41 of the gantry 3. For example, dried fish and seaweed are placed on a net tray and installed on the light shielding plate 41 of the mount 3.

第2の構成は、太陽を追尾して成長効率を高める構成であり、植物その他の光合成体を架台3の遮光板41に設置する。   The second configuration is a configuration in which the sun is tracked to increase the growth efficiency, and plants and other photosynthetic bodies are installed on the light shielding plate 41 of the gantry 3.

第3の構成は、太陽を追尾して美容効果又は治療効果を高める構成であり、日焼け用のベッド又は日光浴用のベッド等を架台3の遮光板41に設置する。   The third configuration is a configuration for tracking the sun to enhance a cosmetic effect or a therapeutic effect, and a suntan bed or a sunbath bed or the like is installed on the light shielding plate 41 of the gantry 3.

第4の構成は、太陽を追尾して蓄熱効果を高める構成であり、蓄熱材又は蓄熱装置(例えば特開2018−091554号公報開示の装置)等を架台3の遮光板41に設置する。   The fourth configuration is a configuration that enhances the heat storage effect by tracking the sun, and a heat storage material or a heat storage device (for example, a device disclosed in Japanese Patent Application Laid-Open No. 2018-091554) or the like is installed on the light shielding plate 41 of the gantry 3.

第5の構成は、太陽を追尾して集光効果を高める構成であり、太陽光を集光する集光装置(例えば特開2015−153681号公報開示の装置)等を架台3の遮光板41に設置する。   The fifth structure is a structure for tracking the sun to enhance the light collecting effect, and a light collecting device (for example, a device disclosed in Japanese Patent Laid-Open No. 2015-153681) for collecting sunlight is a light shielding plate 41 of the gantry 3 Install in

第6の構成は、太陽を追尾して殺菌効果を高める構成であり、太陽光を利用して殺菌を行う殺菌装置(例えば特開2006−688号公報又は特開2015−160146号公報開示の装置)等を架台3の遮光板41に設置する。   The sixth configuration is a configuration that enhances the sterilization effect by tracking the sun, and is a sterilization device that performs sterilization using sunlight (for example, a device disclosed in JP-A-2006-688 or JP-A-2015-160146). And the like) on the light shielding plate 41 of the gantry 3.

また、上記実施の形態及びその変形例において、架台3には、太陽光の入射と遮光を繰り返してコイル状バイメタルを軸方向に沿って伸縮移動させ、コイル状バイメタルの先端に取り付けた永久磁石がコイル内移動することにより、フレミングの右手の法則に従って発電する発電機(実用新案登録第3220436号公報)、風車にソーラパネルを取り付け、風車発電と太陽光発電を合体させた合体発電機(実用新案登録第3218689号公報)を搭載するようにしてもよい。   Moreover, in the said embodiment and its modification, the permanent magnet attached to the front-end | tip of a coiled bimetal is made to the mount frame 3 by extending and retracting a coiled bimetal along an axial direction by repeating sunlight incidence and shading. A generator that generates electricity in accordance with Fleming's right-hand rule by moving in the coil (utility model registration No. 3320436), a solar generator attached to the windmill, and a combined generator that combines windmill power generation and solar power generation (utility model) Registration No. 3218689) may be installed.

また、上記実施の形態及びその変形例において、支持装置10は、昇降駆動源として温度が高くなると軸方向に沿ってび、温度が低くなると軸方向に沿って縮むコイル状バイメタル21を用いているため、作動レバー28と支柱33を用いて作動ロッド24の昇降方向をコイル状バイメタル21との伸縮方向とは逆としている。しかし、コイル状バイメタル21とは逆に、温度が高くなると軸方向に沿って縮み、温度が低くなると軸方向に沿ってびる二方向形状記憶コイルばねを用いることができる。この二方向形状記憶コイルばねを昇降駆動源とすると、二方向形状記憶コイルばねに支持ロッド24を直接接続すればよいので、支持装置10をシンプルな構成とすることができる。 Further, in the embodiment and the modification of the above embodiment, the support apparatus 10 uses a coiled bimetallic 21 shrink in the axial direction when the temperature is higher as an elevating drive source beauty Shin along the axial direction, the temperature is lowered Therefore, using the actuating lever 28 and the support 33, the elevating direction of the actuating rod 24 is opposite to the expanding and contracting direction with the coiled bimetal 21. However, contrary to the coiled bimetal 21, shrinkage in the axial direction when the temperature is high, the temperature can be used Shin building two-way shape memory coil spring along comes to axially lower. When this two-way shape memory coil spring is used as a lifting drive source, the support rod 24 may be directly connected to the two-way shape memory coil spring, so that the support device 10 can have a simple configuration.

二方向形状記憶コイルばねは、特開平3−13551号公報に開示されているように、Ni−Ti合金等の形状記憶合金線をコイルばね形状に形成されていて、加熱すると軸方向に沿って縮み、冷やすと軸方向に沿って長くなる特性を備える。   As disclosed in JP-A-3-13551, the two-way shape memory coil spring is formed of a shape memory alloy wire such as a Ni-Ti alloy in the shape of a coil spring, and is heated along the axial direction. It has a characteristic that it shrinks and becomes longer along the axial direction when it is cooled.

ソーラパネルユニット40が傾動していることを移動確認手段としてインジケータ60により確認できるようにしているが、移動確認手段として転球収納枠部42に振動センサ、マイクロフォン等を設け、球体46の転がりによる振動、球体46同士の衝突を検出することでソーラパネルユニット40の傾動を確認できるようにしてもよい。   The indicator 60 can be used to confirm that the solar panel unit 40 is tilted as a movement confirmation means. However, as the movement confirmation means, a vibration sensor, a microphone or the like is provided in the rolling ball storage frame portion 42 and the ball 46 is rolled. The tilt of the solar panel unit 40 may be confirmed by detecting vibration or collision of the spheres 46 with each other.

また、第1支持装置11は一定の支持高さに維持し、この一定の維持高さを第2支持装置12と第3支持装置13の支持高さの下限値以下とすれば、日の出から日の入りの間で遮光板41を南向き傾斜に維持できる。このことから、第1支持装置11は支持高さを可変とする機能は不要であり、第2支持装置12と第3支持装置13が支持高さを可変とする機能を有すればよい。   Further, if the first support device 11 is maintained at a constant support height, and this constant maintenance height is set to be equal to or lower than the lower limit value of the support heights of the second support device 12 and the third support device 13, the sunrise from the sunset to the sunset. The light shielding plate 41 can be maintained in the south-facing inclination. From this, the first support device 11 does not need the function of making the support height variable, and the second support device 12 and the third support device 13 may have the function of making the support height variable.
