特許文献１、２では、専用フロートは太陽光発電パネルの配置に対する自由度が低い。即ち、太陽光発電パネル配置用フロートにおいては、池等の畔付近で形状の変化に対応させて太陽光発電パネル設置用フロートを配置させることができないこともあり、メンテナンス用フロートを配置させることができないこともある。結果として太陽光発電パネルの配置が制限され、発電量が想定よりも少なくなる。また、太陽光発電パネルのメンテナンスが行えず、発電量が減少する等の不都合を引き起こすことが考えられる。
また、池等の畔付近で形状の変化に対応し、専用フロートを作製することは、その都度、金型の作成等でコストが嵩むことになる。
更に、メンテナンス用フロートは、他のフロートと連結させることが必要であり、ロープ等により係留させる方法では、フロート上を歩くと揺れが大きくなり、安定しないことがあり、連結させる構造を取り付けると、フロート安定性は向上するがフロートを製造する金型の値段が上がり、コストアップとなり、連結での自由度が低下してしまう。 In Patent Documents 1 and 2, the dedicated float has a low degree of freedom with respect to the arrangement of the photovoltaic power generation panels. In other words, in the photovoltaic power generation panel placement float, it may not be possible to place the photovoltaic power generation panel placement float near the shore of the pond or the like, and the maintenance float may be placed. There are things you can't do. As a result, the arrangement of the photovoltaic power generation panels is limited, and the amount of power generation is less than expected. Moreover, it is conceivable that the maintenance of the solar power generation panel cannot be performed, causing inconveniences such as a decrease in the amount of power generation.
In addition, producing a dedicated float corresponding to a change in shape near the shore of a pond or the like increases the cost of creating a mold each time.
Furthermore, it is necessary to connect the float for maintenance with other floats, and in the method of mooring with a rope or the like, when walking on the float, shaking may increase and may not be stable. Although the float stability is improved, the price of the mold for manufacturing the float increases, resulting in an increase in cost and the degree of freedom in connection decreases.

本発明の目的は、太陽光発電パネルの保持用と、足場用と何れかを選択して用い得る太陽光発電用フロート、当該フロートを用いた太陽光発電ユニットを提供することである。 The objective of this invention is providing the solar power generation unit using the float for solar power generation which can select and use either for holding | maintenance of a solar power generation panel, and the object for scaffolds.

本発明の太陽光発電用フロートは、太陽光発電パネルを保持する保持部を備える表面、歩行時の滑り止め凸部を備える裏面の何れかを水上に浮かべて使用可能である。１種類のフロートで、裏面を水上に浮かべることで太陽光発電パネルの保持部材となり、表面を水上に浮かべることで足場とすることができるので、フロートの使用の自由度が高まるのである。その結果として、フロートの製造コストが下がり、太陽光発電ユニットを廉価に構成することができる。 The float for photovoltaic power generation of the present invention can be used by floating on the water either the front surface provided with a holding portion for holding a solar power generation panel or the back surface provided with a non-slip projection during walking. With one type of float, the back surface is floated on the water to become a holding member for the photovoltaic power generation panel, and the surface can be floated on the water to be used as a scaffold, so the degree of freedom of use of the float is increased. As a result, the manufacturing cost of the float is reduced, and the photovoltaic power generation unit can be configured at a low cost.

The connecting pieces 22vf and 22vr and the connecting pieces 24a and 24b are formed at the same height hf from the surface 20F. Here, the height hb and the height hf are substantially equal. As shown in FIG. 3, a connecting piece 22 vf on one short side end of the float 20 and a connecting piece 22 vf on the other end side of the other float 20 are connected to the through-hole 23 by bolts (not shown). By being fixed, the float 20 is vertically connected. Here, any of the connecting piece 22vf of the float 20 and the connecting piece 22vf of the other float 20 may be on the upper side. Adjustments are made by ups and downs of the float. Similarly, the bolt 20 (not shown) is fixed to the through hole 23 by connecting the long connecting pieces 24a and 24b on one longitudinal side of the float 20 and the connecting pieces 24a and 24b on the long side of the other float 20 so that the float 20 Horizontally connected. Here, any of the connecting pieces 24a and 24b of the float 20 and the connecting pieces 24a and 24b of the other floats 20 may be on the upper side. Adjustments are made by ups and downs of the float. In the embodiment, since the float is firmly connected vertically and horizontally through the connecting piece, the scaffold does not float up and down and is easy to walk. The through hole 23 can also be used as a hole for attaching the handrail 70 as shown in FIG.

図４（Ｂ）に示されるように、連結片２２ｖｆ側の表面２０Ｆは、当該連結片２２ｖｆと同じ高さに形成され、歩廊板連結用の一対の凸部２６が形成されている。連結片２２ｖｒ側の表面２０Ｆは、上述された裏面側と同じ高さｈｆに形成されている。
図４（Ｃ）に示されるように、フロートの表面側には、凸部２６が収まるように凹部４６を有する歩廊板４０を載せ、歩廊板４０にポップナット８４が取り付けられており、当該ポップナットにボルト８２を填め入れることで、太陽光発電パネルの第２固定金具９２が取り付けられる。フロート２０のポップナット（保持部材）８４が取り付けられており、当該ポップナットにボルト８２を填め入れることで、太陽光発電パネルの第１固定金（保持部材）９１が取り付けられ、第１固定金具９１、第２固定金具９２に太陽光パネルが取り付けられている。 As shown in FIG. 4B, the surface 20F on the side of the connecting piece 22vf is formed at the same height as the connecting piece 22vf, and a pair of convex portions 26 for connecting the corridor board are formed. The front surface 20F on the connection piece 22vr side is formed at the same height hf as the back surface side described above.
As shown in FIG. 4C, on the surface side of the float, a corridor board 40 having a recess 46 is placed so that the convex part 26 can be accommodated, and a pop nut 84 is attached to the corridor board 40.

図５（Ａ）は実施形態の太陽光発電用フロートの裏面側の平面図であり、図５（Ｂ）、（Ｃ）、（Ｄ）はフロートの側面図であって、図５（Ｃ）は図５（Ａ）のＣ矢視図である。図５（Ｄ）はフロートが連結されて足場として用いられている状態を示す。裏面２０Ｂの表面には足場として用いられた際の滑り止めとなる凸部２８からなる縞模様が形成されている。 FIG. 5A is a plan view of the back surface side of the solar power generation float of the embodiment, and FIGS. 5B, 5C, and 5D are side views of the float, and FIG. These are the C arrow line views of FIG. 5 (A). FIG. 5D shows a state where the float is connected and used as a scaffold. On the front surface of the back surface 20B, a striped pattern made up of convex portions 28 that serve as anti-slip when used as a scaffold is formed.

フロート２０の外側のケーシングは、耐候性のある樹脂、例えば、ポリエチレン（その一例として高密度ポリエチレンが挙げられる）、ポリプロピレンからなり、ケーシング内には発泡樹脂が充填されている。フロートの製造方法は、押出機ダイスを用いて、ポリエチレンの外皮素材がエアーを注入することで金型に密着されポリエチレンのケーシングが完成する。その後、発泡ビーズがケーシング内に充填された後、スチームが加えられ、発泡ビーズが融着させられることでフロートが完成する。 The casing outside the float 20 is made of a weather-resistant resin, such as polyethylene (for example, high-density polyethylene), and polypropylene, and the casing is filled with foamed resin. The float manufacturing method uses an extruder die to inject a polyethylene outer shell material into the mold by injecting air to complete a polyethylene casing. Thereafter, after the foam beads are filled in the casing, steam is added, and the float is completed by fusing the foam beads.

実施形態の改変例では、ケーシング内に発泡樹脂を充填しない空洞フロート２１を用いることができる。図７（Ａ）は実施形態の改変例の空洞フロートの平面図であり、図７（Ｂ）は空洞フロートの断面図である。空洞フロート２１のケーシング内の一部、または、全部を空洞とし、穴２９を設けることで穴から内部に水を入れ、重石として用いることができる。また、水を入れることで、重りとなり、風の侵入防止を図ることもできる。
図７（Ａ）では複数の穴（３個の穴）が設けられているが、一つの穴としてもよい。例えば、図２に示される、裏面２０Ｂが水上に浮かべた状態で縦に３個、横に２個連結されて足場１２０として用いられる６個のフロートの内、１個、又は、２個に空洞フロート２１を組み込むことで、浮力調整と共に、足場及び太陽光発電ユニット１０全体の安定を図ることができる。また、図８に示されるように足場１２０の横に空洞フロート２１を取り付け、風の侵入を防ぐこともできる。 In a modification of the embodiment, a hollow float 21 that does not fill the casing with the foamed resin can be used. FIG. 7A is a plan view of a cavity float according to a modification of the embodiment, and FIG. 7B is a cross-sectional view of the cavity float. A part or all of the inside of the casing of the hollow float 21 is made hollow, and by providing the hole 29, water can be put into the inside from the hole and used as a weight. Moreover, by adding water, it becomes a weight and can also prevent wind intrusion.
Although a plurality of holes (three holes) are provided in FIG. 7A, a single hole may be used. For example, as shown in FIG. 2, one or two of the six floats used as the scaffold 120 by connecting three vertically and two horizontally with the back surface 20B floating on the water is hollow in one or two By incorporating the float 21, it is possible to achieve stability of the scaffolding and the photovoltaic power generation unit 10 as well as buoyancy adjustment.

Furthermore, by not filling the casing with the foamed resin, the inside of the float can be made hollow, and the hollow float 21 that becomes a heavy stone can be configured, so that the manufacturing cost of the float is lowered and the photovoltaic power generation unit can be configured at a low price. .

実施形態では、１つの規格のフロートと、歩廊板とを適宜組み合わせることで、自在形状の太陽光発電ユニットを構成できるので、複雑な形状の湖畔等にも対応可能である。設置工事の為に運搬する際にも、１つの規格のフロートを運べばよいため、運送効率が高い。さらに、太陽光発電保持用のフロートが破損した際にも、足場としていたフロートをひっくり返すことで太陽光発電パネル保持用のフロートとして用いることができるため、現場で予備品を保管しておく必要が無い。 In the embodiment, a free-form solar power generation unit can be configured by appropriately combining one standard float and a walkway board, so that it is possible to cope with a complicated lakeside or the like. When transporting for installation work, it is only necessary to carry one standard float, so the transport efficiency is high. Furthermore, even if the float for holding photovoltaic power generation breaks, it can be used as a float for holding a photovoltaic power generation panel by turning the float that was used as a scaffold, so it is necessary to store spare parts on-site.
