Abstract

PROBLEM TO BE SOLVED: To provide a cover panel for covering a water surface while being floated thereon, which is prevented from easily flying up by a strong wind, and which has a simple structure and has a low manufacturing cost.SOLUTION: The cover panel 1 is composed of synthetic resin plate materials having a specific gravity of <1, and thereby the cover panel is used while being floated on the water surface only by the buoyancy of the plate materials.

Description

本発明は、各種の処理槽や貯留槽等の水面を覆うために用いられる覆蓋パネルに関し、特に、水面に浮かべて覆蓋する覆蓋パネルに関するものである。   The present invention relates to a cover panel used to cover the water surface of various processing tanks and storage tanks, and more particularly to a cover panel that floats and covers the water surface.

従来、例えば、浄水場においては、原水に凝集剤を添加して凝集・沈澱処理した後、この処理水を活性炭処理及び砂濾過処理する処理方法が採用されており、これらの処理は、それぞれ専用の処理槽において行うようにしている。   Conventionally, for example, in water purification plants, after a coagulant is added to raw water and coagulation / sedimentation treatment, activated water treatment and sand filtration treatment of this treated water has been adopted. This is done in the treatment tank.

ところで、これらの処理を行う処理槽は、通常、上部を解放したままのものが多く用いられており、このため、大気中の塵埃が処理槽内に侵入したり、処理槽内に太陽光が直接照射されることによって藻類が大量に発生することにより、処理水の処理工程に支障が生じたり、処理水の品質が低下するという問題があった。   By the way, many processing tanks that perform these processes are usually used with the upper part opened. For this reason, dust in the atmosphere enters the processing tank or sunlight enters the processing tank. When a large amount of algae are generated by direct irradiation, there is a problem that the treatment process of the treated water is hindered or the quality of the treated water is deteriorated.

そこで、フロートを備えたパネルを水面に浮かべて覆蓋する覆蓋パネルが提案されている(例えば、特許文献1及び2参照)。   Accordingly, a cover panel that floats and covers a panel provided with a float on the water surface has been proposed (see, for example, Patent Documents 1 and 2).

しかしながら、従来の覆蓋パネルは、フロートを設ける必要があることから、強風によって覆蓋パネルが舞い上がり飛散しやすく、また、これを防止するための構造が複雑になり、製造コストが高くなるという問題を有していた。   However, since the conventional cover panel needs to be provided with a float, the cover panel easily rises and scatters due to strong winds, and the structure for preventing this is complicated and the manufacturing cost increases. Was.

また、水面に浮かべて覆蓋するものではないが、処理槽を覆う技術に関して、水処理における生物処理を促進するために特定の波長領域の光を透過する選択透過性を有するようにした遮光板が提案されている(例えば、特許文献3参照)が、従来の水面に浮かべて覆蓋するものの場合、フロートを設ける必要があることから、生物処理に必要な量の光を透過するように構成することが困難であった。   In addition, although it is not intended to float and cover the water surface, with regard to the technology for covering the treatment tank, there is a light-shielding plate that has selective permeability that transmits light in a specific wavelength region in order to promote biological treatment in water treatment. Proposed (for example, see Patent Document 3) is to float on a conventional water surface, and since it is necessary to provide a float, it is configured to transmit the amount of light necessary for biological treatment. It was difficult.

本発明は、上記従来の覆蓋パネルの有する問題点に鑑み、強風によって覆蓋パネルが舞い上がって飛散しにくく、構造が簡易で、製造コストが低廉な、水面に浮かべて覆蓋する覆蓋パネルを提供することを第1の目的とする。   SUMMARY OF THE INVENTION In view of the problems of the above conventional cover panel, the present invention provides a cover panel that floats on the water surface and covers the water surface, which is difficult to scatter and fly by strong wind, has a simple structure, and is low in manufacturing cost. Is the first purpose.

また、本発明は、生物処理を促進するために特定の波長領域の光を透過する選択透過性を有するように構成した水面に浮かべて覆蓋する覆蓋パネルを提供することを第2の目的とする。   In addition, a second object of the present invention is to provide a cover panel that floats and covers a water surface that is configured to have selective permeability that transmits light in a specific wavelength region in order to promote biological treatment. .

上記第1の目的を達成するため、本発明の覆蓋パネルは、水面に浮かべて覆蓋する覆蓋パネルにおいて、覆蓋パネルを比重が1未満の合成樹脂製の板材から構成し、板材の浮力のみによって水面に浮かべて用いられることを特徴とする。   In order to achieve the first object, a cover panel according to the present invention is a cover panel that floats and covers a water surface. The cover panel is formed of a synthetic resin plate material having a specific gravity of less than 1, and the surface of the cover panel is formed only by the buoyancy of the plate material. It is used for floating.

この場合において、覆蓋パネルを、天板部と、該天板部の外周に形成された周壁部とを有するようにすることができる。   In this case, the cover panel can have a top plate portion and a peripheral wall portion formed on the outer periphery of the top plate portion.

また、前記周壁部にスリットを形成することができる。   Moreover, a slit can be formed in the said surrounding wall part.

また、前記天板部に小孔を形成することができる。   Moreover, a small hole can be formed in the top plate part.

また、前記天板部を凹凸形状に形成し、凹部に小孔を形成することができる。   Further, the top plate portion can be formed in a concavo-convex shape, and a small hole can be formed in the concave portion.

また、上記第2の目的を達成するため、板材を450〜600nmの波長領域の光を透過する選択透過性を有するように構成することができる。   Moreover, in order to achieve the said 2nd objective, a board | plate material can be comprised so that it may have the selective permeability which permeate | transmits the light of the wavelength range of 450-600 nm.

Therefore, it is possible to provide a cover panel that floats on the surface of the water and covers the water surface, which has a simple structure and a low manufacturing cost.

また、覆蓋パネルを、天板部と、該天板部の外周に形成された周壁部とを有するようにすることにより、覆蓋パネル同士が重なり合うことを防止するとともに、覆蓋パネルの天板部の下面に空気層が形成されにくく、強風によって覆蓋パネルが舞い上がって飛散しにくくすることができ、覆蓋パネルの設置安定性を向上することができる。   In addition, the cover panel has a top plate portion and a peripheral wall portion formed on the outer periphery of the top plate portion, thereby preventing the cover panels from overlapping each other and It is difficult for an air layer to be formed on the lower surface, and the cover panel can be prevented from rising and scattering by strong wind, and the installation stability of the cover panel can be improved.

また、前記周壁部にスリットを形成することにより、覆蓋パネルの天板部の下面に入り込んだ空気(槽内で発生した気体を含む。)をスリットを通して放出することができ、覆蓋パネルの設置安定性を向上することができる。   In addition, by forming a slit in the peripheral wall portion, air (including gas generated in the tank) that has entered the lower surface of the top panel portion of the cover panel can be discharged through the slit, and the cover panel can be installed stably. Can be improved.

また、前記天板部に小孔を形成することにより、覆蓋パネルの天板部の下面に入り込んだ空気(槽内で発生した気体を含む。)を小孔を通して放出することができ、覆蓋パネルの設置安定性を向上することができるとともに、小孔を覆蓋パネルを移動させる際の引っ掛け部や隣接設置した覆蓋パネル同士を接続する場合の接続部として利用することができる。   Further, by forming a small hole in the top plate portion, air (including gas generated in the tank) that has entered the lower surface of the top plate portion of the cover panel can be discharged through the small hole, and the cover panel It is possible to improve the installation stability, and to use it as a hook when moving the cover panel through the small holes or as a connection part when connecting the cover panels installed adjacent to each other.

また、前記天板部を凹凸形状に形成し、凹部に小孔を形成することにより、覆蓋パネルの強度を高めるとともに、天板部の上面に降った雨を小孔を通して排出することができ、覆蓋パネルの設置安定性を向上することができる。   In addition, by forming the top plate portion in a concavo-convex shape and forming a small hole in the recess, the strength of the cover panel can be increased, and rain that has fallen on the top surface of the top plate portion can be discharged through the small hole, The installation stability of the cover panel can be improved.

また、板材を450〜600nmの波長領域の光を透過する選択透過性を有するように構成することにより、生物処理を促進するために特定の波長領域の光を透過する選択透過性を有するように構成した水面に浮かべて覆蓋する覆蓋パネルを提供することができる。   In addition, by configuring the plate material to have selective permeability that transmits light in the wavelength region of 450 to 600 nm, it has selective permeability that transmits light in a specific wavelength region in order to promote biological treatment.

以下、本発明の覆蓋パネルの実施の形態を、図面に基づいて説明する。   Hereinafter, embodiments of the cover panel of the present invention will be described with reference to the drawings.

図1に、本発明の覆蓋パネルの一実施例を示す。
この覆蓋パネル1は、水面に浮かべて覆蓋するもので、覆蓋パネル1を比重が1未満の合成樹脂製の板材から構成し、板材の浮力のみによって水面に浮かべて用いることができるようにしている。
FIG. 1 shows an embodiment of the cover panel of the present invention.
This cover panel 1 floats on the water surface and covers it. The cover panel 1 is made of a synthetic resin plate material having a specific gravity of less than 1, and can be used by floating on the water surface only by the buoyancy of the plate material. .

覆蓋パネル1の形状は、矩形、円形、隣接設置する覆蓋パネルと嵌合する形状等の任意の形状とすることができる。
また、覆蓋パネル1の大きさ及び板材の厚さも、覆蓋する槽の形状に応じて任意の大きさ及び厚みとすることができ、本実施例においては、例えば、縦L1:300〜3000mm、横L2:300〜3000mm、後述の周壁部12の高さL3:数mm〜200mm、板材の厚さ:1〜10mmの平面形状が正方形又は長方形の覆蓋パネル1(図示のものは、縦L1:900mm、横L2:900mm、周壁部12の高さL3:50mm、板材の厚さ:3mm。)を組み合わせて用いるようにしている。
ちなみに、浄水場の緩速濾過池(8210mm×3650mm)に適用する場合は、縦L1:900mm、横L2:900mmの覆蓋パネル1を、縦方向に9列、横方向に4列並べることにより、緩速濾過池の水面をほぼ覆うことができる。
The shape of the cover panel 1 can be an arbitrary shape such as a rectangle, a circle, or a shape that fits with a cover panel that is adjacently installed.
Further, the size of the cover panel 1 and the thickness of the plate material can also be set to any size and thickness depending on the shape of the tank to be covered. In this embodiment, for example, the length L1: 300 to 3000 mm, the width L2: 300 to 3000 mm, height L3 of the peripheral wall portion 12 to be described later: several mm to 200 mm, plate material thickness: 1 to 10 mm, and a planar cover panel 1 having a square or rectangular planar shape (shown is vertical L1: 900 mm) , Width L2: 900 mm, height L3 of the peripheral wall portion 12: 50 mm, plate thickness: 3 mm).
By the way, when applying to the slow filtration pond (8210mm x 3650mm) of the water purification plant, by arranging the cover panel 1 of length L1: 900mm, width L2: 900mm in 9 rows in the vertical direction and 4 rows in the horizontal direction, The water surface of the slow filtration pond can be almost covered.

覆蓋パネル1を構成する合成樹脂には、比重が1未満の合成樹脂、特に、未発泡で比重が1未満であり、化学的に安定し水に対する溶出成分がなく、硬質で、かつ、引っ張りや折り曲げに対して大きな強度特性を有するポリプロピレン(比重:0.9〜0.92)を好適に用いることができる。
合成樹脂には、耐候性を向上するために、紫外線吸収剤(光安定剤)、酸化防止剤等の合成樹脂添加剤を添加することができる。
The synthetic resin constituting the cover panel 1 is a synthetic resin having a specific gravity of less than 1, in particular, unfoamed and specific gravity of less than 1, chemically stable and free from water-eluting components, hard, Polypropylene (specific gravity: 0.9 to 0.92) having a large strength property against bending can be suitably used.
In order to improve the weather resistance, synthetic resin additives such as an ultraviolet absorber (light stabilizer) and an antioxidant can be added to the synthetic resin.

また、合成樹脂には、処理槽内に太陽光が直接照射されることによって藻類が大量に発生することにより、処理水の処理工程に支障が生じたり、処理水の品質が低下することを防止するために、遮光性を付与する顔料を添加するようにする。
この顔料には、黒色の顔料のほか、緑色の顔料を添加することができる。
特に、緑色の顔料を添加することにより、板材を450〜600nm、より好ましくは、500〜560nmの緑色の波長領域の光を透過する選択透過性を有するように構成することができ、これにより、浄水場の緩速濾過池における生物処理を促進することができる。
In addition, the synthetic resin prevents a large amount of algae from being directly irradiated with sunlight into the treatment tank, thereby preventing troubles in the treatment process of the treated water and deterioration of the quality of the treated water. For this purpose, a pigment imparting light-shielding properties is added.
In addition to a black pigment, a green pigment can be added to this pigment.
In particular, by adding a green pigment, the plate material can be configured to have a selective transmission property that transmits light in a green wavelength region of 450 to 600 nm, more preferably, 500 to 560 nm. Biological treatment in the slow filtration pond of the water purification plant can be promoted.

覆蓋パネル1は、平板状のものを使用することもできるが、本実施例のように、天板部11と、天板部11の外周に形成された周壁部12とから構成することが好ましい。
なお、周壁部12の高さL3は、本実施例においては、50mmに形成するようにしているが、設置状況等に応じて、数mm〜200mm程度の範囲で任意に設定することができる。
これにより、周壁部12によって、隣接設置した覆蓋パネル1同士が重なり合うことを防止するとともに、覆蓋パネル1の天板部11の下面に空気層が形成されにくく、強風によって覆蓋パネル1が舞い上がって飛散しにくくすることができ、覆蓋パネル1の設置安定性を向上することができる。
Although the cover panel 1 can also use a flat thing, it is preferable to comprise from the top-plate part 11 and the surrounding wall part 12 formed in the outer periphery of the top-plate part 11 like a present Example. .
In addition, although the height L3 of the surrounding wall part 12 is formed in 50 mm in a present Example, according to installation conditions etc., it can set arbitrarily in the range of about several mm-200 mm.
Thereby, while the adjacent cover panels 1 are prevented from overlapping with each other by the peripheral wall portion 12, an air layer is hardly formed on the lower surface of the top plate portion 11 of the cover panel 1, and the cover panel 1 is soared and scattered by a strong wind. The installation stability of the cover panel 1 can be improved.

この場合、周壁部12に天板部11に達するスリット(細隙)13を形成することが好ましい。これにより、覆蓋パネル1の天板部11の下面に入り込んだ空気(槽内で発生した気体を含む。)をスリット13を通して放出することができ、覆蓋パネル1の設置安定性を向上することができる。
なお、スリット13は、本実施例においては、合成樹脂製の板材からなる素材を折り曲げ加工して天板部11及び周壁部12を形成する際に、周壁部12の角部を溶接や接着しないようにすることで、容易に形成することができる。
なお、スリット13は、周壁部12の角部の周壁部12の任意の位置に形成することができ、また、その形状も、縦長、横長、円形等の任意の形状とすることができる。
In this case, it is preferable to form a slit (slit) 13 reaching the top plate portion 11 in the peripheral wall portion 12. Thereby, the air (including gas generated in the tank) that has entered the lower surface of the top plate portion 11 of the cover panel 1 can be discharged through the slit 13, and the installation stability of the cover panel 1 can be improved. it can.
In this embodiment, the slit 13 is not welded or bonded to the corner of the peripheral wall portion 12 when the top plate portion 11 and the peripheral wall portion 12 are formed by bending a material made of a synthetic resin plate material. By doing so, it can be formed easily.
In addition, the slit 13 can be formed in the arbitrary positions of the peripheral wall part 12 of the corner | angular part of the peripheral wall part 12, and the shape can also be made into arbitrary shapes, such as longitudinally long, laterally long, and circular.

また、天板部11には、小孔14、15を形成するようにしている。
これにより、覆蓋パネル1の天板部11の下面に入り込んだ空気(槽内で発生した気体を含む。)を小孔14、15を通して放出することができ、覆蓋パネル1の設置安定性を向上することができるとともに、小孔14、15を覆蓋パネル1を移動させる際の引っ掛け部や隣接設置した覆蓋パネル1同士を接続する場合の接続部として利用することができる。
なお、小孔14、15は、その大きさを、数mm〜10mm程度の範囲で任意に設定することができるが、覆蓋パネル1を移動させる際の引っ掛け部として利用する場合には、それより大きい20〜50mm程度の大きさとすることが望ましく、また、その形状も、円形のほか、長円形等の任意の形状とすることができる。
Further, small holes 14 and 15 are formed in the top plate portion 11.
Thereby, the air (including the gas generated in the tank) that has entered the lower surface of the top plate portion 11 of the cover panel 1 can be discharged through the small holes 14 and 15, and the installation stability of the cover panel 1 is improved. In addition, the small holes 14 and 15 can be used as a hook when moving the cover panel 1 or as a connection part when connecting adjacent cover panels 1 to each other.
In addition, although the magnitude | sizes of the small holes 14 and 15 can be arbitrarily set in the range of about several mm to 10 mm, in the case of using them as the hooks when moving the cover panel 1, It is desirable to have a large size of about 20 to 50 mm, and the shape can be any shape such as an oval other than a circle.

また、図2に示す本発明の覆蓋パネルの変形実施例のように、天板部11を凹凸形状、具体的には、中心部11aと周縁部11cを凸状に、その中間部11bを凹状に形成し、凹状に形成した中間部11bに小孔14を形成することにより、覆蓋パネル1の強度を高めるとともに、天板部11の上面に降った雨を小孔14を通して排出することができ、覆蓋パネルの設置安定性を向上することができる。
この覆蓋パネルにおいても、図1に示す実施例と同様、周壁部12に天板部11に達するスリット(図示省略)を形成することが好ましい。
Further, like the modified embodiment of the cover panel of the present invention shown in FIG. 2, the top plate portion 11 has an uneven shape, specifically, the central portion 11a and the peripheral portion 11c have a convex shape, and the intermediate portion 11b has a concave shape. By forming the small hole 14 in the concave intermediate portion 11b, the strength of the cover panel 1 can be increased, and rain that has fallen on the top surface of the top plate portion 11 can be discharged through the small hole 14. The installation stability of the cover panel can be improved.
Also in this cover panel, it is preferable to form a slit (not shown) reaching the top plate portion 11 in the peripheral wall portion 12 as in the embodiment shown in FIG.

このように、この覆蓋パネル1によれば、覆蓋パネル1を比重が1未満の合成樹脂製の板材から構成し、板材の浮力のみによって水面に浮かべて用いられるようにすることにより、フロートを設ける必要がないことから、強風によって覆蓋パネルが舞い上がって飛散しにくく、構造が簡易で、製造コストが低廉な、水面に浮かべて覆蓋する覆蓋パネルを提供することができる。   Thus, according to this cover panel 1, the cover panel 1 is made of a synthetic resin plate material having a specific gravity of less than 1, and is floated on the water surface only by the buoyancy of the plate material, thereby providing a float. Since it is not necessary, it is possible to provide a cover panel that floats on the surface of the water and covers the water surface, which has a simple structure and is low in manufacturing cost.

以上、本発明の覆蓋パネルについて、その実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜その構成を変更することができるものである。   The cover panel of the present invention has been described based on the embodiments thereof. However, the present invention is not limited to the configurations described in the above embodiments, and the configurations are appropriately changed without departing from the spirit of the present invention. It is something that can be done.

本発明の覆蓋パネルは、強風によって覆蓋パネルが舞い上がって飛散しにくく、構造が簡易で、製造コストが低廉である特性を有していることから、水面に浮かべて覆蓋する覆蓋パネルの用途に好適に用いることができる。   The cover panel of the present invention is suitable for use as a cover panel that floats on the surface of the water and covers it because it has a characteristic that the cover panel is not easily scattered and scattered by strong winds, has a simple structure, and is low in manufacturing cost.
