Description

本発明は、太陽光発電装置の設置構造に係り、更に詳しくは、支柱を介して太陽電池パネルを地上に設置する場合の構造の改良に関する。 The present invention relates to an installation structure of a solar power generation device, more particularly to structure modifications when installing the solar panels on the ground via the post.

近時、太陽光発電装置が環境破壊のない代替エネルギー源として注目され、例えば、建物の屋根に設置される光景が多く見受けられるようになっている。
この太陽光発電装置を遊休地等の屋外に設置する態様としては、太陽電池パネルを地上に直接設置する態様が存在するが、この場合には、太陽電池パネルの設置領域が土地の有効利用を狭めてしまう、という不都合をもたらす。
このような不都合は、例えば、特許文献１に開示されるように、地上に支柱を立設し、当該支柱の上部に太陽電池パネルを支持させることで解消することができる。 Recently, photovoltaic power generation devices have attracted attention as an alternative energy source without environmental destruction, and for example, many scenes installed on the roofs of buildings have been seen.
As a mode of installing this solar power generation device outdoors such as an idle land, there is a mode of directly installing a solar cell panel on the ground. In this case, the installation area of the solar cell panel is used for effective use of land. This causes the inconvenience of narrowing.
Such inconvenience can be solved by, for example, setting up a support on the ground and supporting the solar cell panel on the upper part of the support as disclosed in Patent Document 1.

特開平８−８８３８９号公報JP-A-8-88389

特許文献１に記載された太陽光発電装置は、太陽電池パネルを支持する支柱の下端部にブロックを設け、当該ブロックを地中に埋設して設置する構造となっている。
しかしながら、特許文献１記載の設置構造は、ブロックを地中に埋設するだけの構造であって、ブロックの埋設強度自体を堅牢にする構成とはなっていない。
また、特許文献１記載の太陽電池パネルは、その受光面に強風が吹き当てられたときの受光面の角度調整機能は存在せず、風圧に起因した曲げ応力等のエネルギーが支柱及びブロックに大きく作用する構造となっている。従って、発電量を多く確保するために平面積の大きい太陽電池パネルの設置には適していない、という不都合もある。 The solar power generation device described in Patent Document 1 has a structure in which a block is provided at a lower end portion of a support column that supports a solar cell panel, and the block is embedded in the ground.
However, the installation structure described in Patent Document 1 is a structure that only embeds a block in the ground, and does not have a structure that makes the embedding strength of the block itself robust.
Moreover, the solar cell panel described in Patent Document 1 has no function of adjusting the angle of the light receiving surface when strong wind is blown onto the light receiving surface, and energy such as bending stress due to wind pressure is greatly applied to the columns and blocks. It has a working structure. Therefore, there is also an inconvenience that it is not suitable for installation of a solar cell panel having a large plane area in order to secure a large amount of power generation.

[発明の目的]

本発明によれば、埋設構造体がコンクリートを介して地中に埋設される構造であるから、埋設構造体自体の設置強度を高めることができるとともに、支柱の支持を安定した状態に保つことができる。また、支柱と埋設構造体とが別体であり、両者が締結具を介して連結される構造であるため、それぞれの大きさを一体型よりも小さくでき、搬送時や設置時の取り扱いに伴う作業負担を軽減することができる。
しかも、太陽電池パネルは所定の風速値を上回ったときに角度変位して水平姿勢に保たれる構成であるから、風圧が太陽電池パネルに大きく作用した場合に加えられる支柱、埋設構造体への負荷も大幅に緩和され、設置構造の耐久性を十分に維持することができる。
更に、紙管内に鉄筋骨材を配置して紙管内空間にコンクリートを打設する（流し込む）構造では、設置現場に形成される穴内に紙管を配置した状態で鉄筋骨材を配置し、紙管内にコンクリートを打設するだけで埋設構造体が形成可能となる。しかも、紙管の内外を通じる穴を通じてコンクリートが紙管の外周側にも流れ込む構造となるため、コンクリート打設作業の工程を最小化することができる。

In addition, since the strut and the embedded structure are separate bodies and both are connected via a fastener, the size of each can be made smaller than that of the integrated type, which is associated with handling during transportation and installation. Work burden can be reduced.
Moreover, since the solar cell panel is configured to be angularly displaced and maintained in a horizontal posture when the wind speed exceeds a predetermined wind speed value, the support to the column and embedded structure added when the wind pressure is greatly applied to the solar cell panel The load is also greatly reduced, and the durability of the installation structure can be sufficiently maintained.

Moreover, the solar cell panel 11 is controlled via a controller so that it may return to an origin position, when it detects that the wind speed sensor 14 exceeded the preset wind speed value.

前記支柱１２は、その直径が４００ｍｍ、長さが４５００ｍｍとなる金属製の筒状体からなり、その下部が締結具２０を介して埋設構造体１３の上部に連結されている。これを更に詳述すると、支柱１２の下部にはボルト挿入孔２３を周方向複数箇所に備えたフランジ２５が設けられており、ボルト挿入孔２３内に挿通されるボルト２６のねじ軸部２６Ａにナット２８を締め付けることで支柱１２が埋設構造体１３の上部に連結されて当該埋設構造体１３上に支持されるように構成されている。ここにおいて、前記ボルト２６及びナット２８により締結具２０が構成されている。なお、本実施形態における支柱１２は、一本の筒状体であるが、長さ方向に沿って複数に分割し、これを設置現場で相互に連結することでもよい。   The column 12 is made of a metal cylindrical body having a diameter of 400 mm and a length of 4500 mm, and a lower part thereof is connected to an upper part of the embedded structure 13 via a fastener 20. More specifically, flanges 25 having bolt insertion holes 23 at a plurality of locations in the circumferential direction are provided at the lower part of the support column 12, and the screw shaft portion 26 </ b> A of the bolt 26 inserted into the bolt insertion hole 23 is provided. By tightening the nut 28, the support column 12 is connected to the upper portion of the embedded structure 13 and is supported on the embedded structure 13. Here, the fastener 20 is constituted by the bolt 26 and the nut 28. In addition, although the support | pillar 12 in this embodiment is a single cylindrical body, it may be divided | segmented into multiple along a length direction, and this may be mutually connected in the installation site.

前記埋設構造体１３は、第１実施形態では、プレキャストコンクリート又はヒューム管からなる中空の支持筒により構成されている。この埋設構造体１３は、地面に形成された穴ｈの内側にコンクリートＣの流し込み空間Ｓを形成する状態で埋設されるものであり、その直径、長さは、１０００ｍｍ、２０００ｍｍのものが用いられている。また、埋設構造体１３は、内部にコンクリートを流し込むことで中実化され、その際に、上端部に前記ボルト２６の頭部を下側にして埋め込み固定することにより、ボルト２６のねじ軸部２６Ａを上方に突出させた状態で当該ボルト２６を固定するようになっている。   In the first embodiment, the embedded structure 13 is constituted by a hollow support cylinder made of precast concrete or a fume tube. This embedded structure 13 is embedded in a state where a concrete C pouring space S is formed inside a hole h formed in the ground, and the diameter and length thereof are 1000 mm and 2000 mm. ing. The embedded structure 13 is solidified by pouring concrete into the interior, and at that time, the screw shaft portion of the bolt 26 is fixed by embedding and fixing the head of the bolt 26 on the upper end portion. The bolt 26 is fixed in a state where 26A protrudes upward.

なお、図１中符号３１は、太陽電池パネル１１の側端に設けられたフランジ３２を介して太陽電池パネル１１の仰角を変位させるための回転軸であり、同図中符号３４は、太陽電池パネル１１を水平面内で回転させるための回転部材を示す。太陽電池パネル１１の変位若しくは回転は、図示しないコントローラを介して制御される。   In addition, the code | symbol 31 in FIG. 1 is a rotating shaft for displacing the elevation angle of the solar cell panel 11 via the flange 32 provided in the side end of the solar cell panel 11, and the code | symbol 34 in the figure is a solar cell. The rotation member for rotating the panel 11 within a horizontal surface is shown. The displacement or rotation of the solar cell panel 11 is controlled via a controller (not shown).

次に、第１実施形態における太陽光発電装置１０の設置方法について、図２を参照しながら説明する。   Next, the installation method of the solar power generation device 10 in 1st Embodiment is demonstrated, referring FIG.

図２（Ａ）に示されるように、穴あけ装置４０を用いて地面に穴ｈをあける。この穴ｈの内径及び深さは、埋設構造体１３の直径よりも大きく、且つ、長さよりも長い深さとされ、これにより埋設構造体１３の外周側と穴ｈとの間にコンクリートＣを流し込む空間Ｓが形成される。穴ｈをあけた後、埋設構造体１３を穴ｈ内に配置し（図２（Ｂ）参照）、穴ｈと埋設構造体１３との間に形成されたコンクリートＣの流し込み空間Ｓと、埋設構造体１３の内側空間内にコンクリートＣを流し込む（打設する）。埋設構造体１３の内側へのコンクリート流し込みを終了する前の段階でボルト２６を埋設構造体１３の内側所定箇所に配置し、当該ボルト２６の頭部回りを固定する（図２（Ｃ）参照）。なお、図示例では、２個のボルト２６を示しているが、実際には、それよりも多い数のボルトが固定される。   As shown in FIG. 2 (A), a hole h is made in the ground using a hole making device 40. The inner diameter and depth of the hole h are larger than the diameter of the embedded structure 13 and longer than the length, whereby the concrete C is poured between the outer peripheral side of the embedded structure 13 and the hole h. A space S is formed. After making the hole h, the embedded structure 13 is placed in the hole h (see FIG. 2B), and the concrete C pouring space S formed between the hole h and the embedded structure 13 is embedded. Concrete C is poured (placed) into the inner space of the structure 13. Before the concrete pouring into the embedded structure 13 is finished, the bolts 26 are arranged at predetermined positions inside the embedded structure 13 and fixed around the heads of the bolts 26 (see FIG. 2C). . In the illustrated example, two bolts 26 are shown, but actually, a larger number of bolts are fixed.

コンクリートＣを硬化させた後において、ボルト２６のねじ軸部２６Ａを支柱１２のフランジ２５に形成されたボルト挿入孔２５Ａに挿通する。そして、ねじ軸部２６Ａにナット２８を締め付けることで、支柱１２と埋設構造体１３とが相互に連結され、これにより、太陽電池パネル１１が地上の所定高さ位置に支持されることとなる（図２（Ｄ）参照）。
なお、太陽電池パネル１１は、日の出以後、日没までの間にわたり、予め設定された太陽の位置データを制御基準として仰角及び方位を変化させて太陽を追尾するが、風速センサ１４によって検出される風速値が所定値を上回ったときに原点位置に戻るように制御される。 After the concrete C is hardened, the screw shaft portion 26 </ b> A of the bolt 26 is inserted into the bolt insertion hole 25 </ b> A formed in the flange 25 of the column 12. Then, by tightening the nut 28 on the screw shaft portion 26A, the support column 12 and the embedded structure 13 are connected to each other, whereby the solar cell panel 11 is supported at a predetermined height position on the ground ( (See FIG. 2D).
The solar battery panel 11 tracks the sun by changing the elevation angle and the azimuth from the sun up to sunset until the sun is set as a control reference, but is detected by the wind speed sensor 14. Control is performed to return to the origin position when the wind speed value exceeds a predetermined value.

従って、このような第１実施形態によれば、埋設構造体１３全体がコンクリートＣを介して地面の穴ｈ内に埋設され、当該埋設構造体１３の上部と支柱１２の下部とを締結具２０で連結する構成としたるから、埋設構造体１３を堅牢な状態で埋設でき、これに支持される支柱１２の支持強度を強固に確保することができる。
また、太陽電池パネル１１は、風速が所定の値を上回ったときに略水平姿勢に角度変位される構成としているため、風圧の影響を受け難くでき、この点からも、支柱１２及び埋設構造体１３に対する過大な負荷軽減を図ることができる。 Therefore, according to the first embodiment, the entire embedded structure 13 is embedded in the hole h in the ground via the concrete C, and the upper portion of the embedded structure 13 and the lower portion of the support column 12 are connected to the fastener 20. Therefore, the embedded structure 13 can be embedded in a robust state, and the supporting strength of the column 12 supported by the embedded structure 13 can be secured firmly.
Moreover, since the solar cell panel 11 is configured to be angularly displaced in a substantially horizontal posture when the wind speed exceeds a predetermined value, it can be hardly affected by the wind pressure. From this point as well, the column 12 and the embedded structure Excessive load reduction for 13 can be achieved.

次に、本発明の前記以外の実施形態について図３以下を参照しながら説明する。なお、以下の説明において、前記第１実施形態と同一若しくは同等の構成部分については同一符合を用いるものとし、説明を省略若しくは簡略にする。   Next, other embodiments of the present invention will be described with reference to FIG. In the following description, the same reference numerals are used for the same or equivalent components as in the first embodiment, and the description is omitted or simplified.

図３（Ａ）〜（Ｄ）には、第２実施形態に係る設置工程が示されている。この第２実施形態は、紙管５０に鉄筋骨材５１を配置してコンクリートＣを打設することで埋設構造体１３が形成されるところに特徴を有する。紙管５０は、その外周部分に複数の連通穴５３が形成されており、当該連通穴５３を介して紙管５０の内外にコンクリートＣが流通するように設けられている。
コンクリートＣを打設してボルト２６を固定する際の要領は、第１実施形態と同じであり、また埋設構造体１３に支柱１２の下部を連結する構成も第１実施形態と同じである。 The installation process which concerns on 2nd Embodiment is shown by FIG. The second embodiment is characterized in that the embedded structure 13 is formed by placing the rebar aggregate 51 in the paper tube 50 and placing concrete C therein. The paper tube 50 has a plurality of communication holes 53 formed in the outer peripheral portion thereof, and is provided so that the concrete C flows into and out of the paper tube 50 through the communication holes 53.
The procedure for placing the concrete C and fixing the bolts 26 is the same as in the first embodiment, and the configuration for connecting the lower portion of the support column 12 to the embedded structure 13 is the same as in the first embodiment.

このような第２実施形態によれば、紙管５０を用いているため、廉価に埋設構造体１３を形成することができる他、紙管５０に連通穴５３を設けていることで、紙管５０内にコンクリートＣを流し込むだけで、紙管５０と穴ｈとの間の空間ＳにもコンクリートＣを流し込むことができ、コンクリートＣの打設工程が簡略化できる。   According to the second embodiment, since the paper tube 50 is used, the embedded structure 13 can be formed at a low cost, and the communication hole 53 is provided in the paper tube 50, whereby the paper tube The concrete C can be poured into the space S between the paper tube 50 and the hole h only by pouring the concrete C into the 50, and the concrete C placing process can be simplified.

図４（Ａ）〜（Ｃ）には、第３実施形態に係る設置工程が示されている。この第３実施形態は、ボルト２６が予め固定されたプレキャストコンクリートからなる埋設構造体１３を用い、当該埋設構造体１３が中実構造となる角柱体、円柱体、円錐体等により構成されて任意に選択可能とした点に特徴を有する。このような第３実施形態では、埋設構造体１３の外周側にのみコンクリートを打設するだけで当該埋設構造体１３を地面内に固定できる。   4A to 4C show an installation process according to the third embodiment. In this third embodiment, an embedded structure 13 made of precast concrete with bolts 26 fixed beforehand is used, and the embedded structure 13 is composed of a prismatic body, a cylinder, a cone, or the like having a solid structure.
