本発明の雨水集水器によれば、より簡単・安価な構成で、より効果的に集水及び貯水できるという特別有利な効果を奏する。   According to the rainwater collector of the present invention, there is a particularly advantageous effect that water can be collected and stored more effectively with a simpler and less expensive configuration.

本発明に係る雨水集水器の形態例を示す断面図である。It is sectional drawing which shows the example of a form of the rain water collector which concerns on this invention.

以下、本発明の雨水集水器に係る形態例を、添付図面（図１）に基づいて詳細に説明する。図１（ａ）は平面図であり、図１（ｂ）は断面図である。この雨水集水器は、貯水槽１０、集水用シート２０、及び球体３０を構成要素としている。   Hereinafter, the example which concerns on the rain water collector of this invention is demonstrated in detail based on an accompanying drawing (FIG. 1). FIG. 1A is a plan view, and FIG. 1B is a cross-sectional view. The rainwater collector includes a water tank 10, a water collection sheet 20, and a sphere 30 as constituent elements.

貯水槽１０は、底部及び側周部によって構成されて上面が開口して設けられている。上面全面が大きく開口しており、集水用シート２０の外周が固定され、その集水用シート２０の内部がフリー状態に張られている。本形態例によれば、集水用シート２０が、貯水槽１０の上端周縁（側周部の上端部）に鍔状に設けられたフランジ部１１に固定されていることで張られた状態になっている。固定方法は、例えば集水用シート２０に設けられた多数の鳩目穴２０ａを利用すればよい。なお、貯水槽１０は、破れない適切な強度を備えるものであれば安価な材料で構成すればよく、水平に均された地面１５に設置される。また、１２は蛇口（コック）であり、１３は排水用のドレンバルブである。   The water storage tank 10 is configured by a bottom portion and a side peripheral portion, and is provided with an upper surface opened. The entire upper surface has a large opening, the outer periphery of the water collecting sheet 20 is fixed, and the inside of the water collecting sheet 20 is stretched in a free state. According to the present embodiment, the water collecting sheet 20 is stretched by being fixed to the flange portion 11 provided in a bowl shape on the upper end periphery (the upper end portion of the side peripheral portion) of the water storage tank 10. It has become. As a fixing method, for example, a large number of eyelet holes 20a provided in the water collecting sheet 20 may be used. The water tank 10 may be made of an inexpensive material as long as it has an appropriate strength that does not break, and is installed on the ground 15 that is leveled horizontally. Further, 12 is a faucet (cock), and 13 is a drain valve for drainage.

集水用シート２０は、貯水槽１０の上面を覆うように張設され、非透水性で柔軟性のある材質によってシート状に設けられ、シート面の自重で最も垂れ下がる位置となる中央部に通水孔２１が設けられている。この集水用シート２０は、雨水を適切に受けて集水するように機能すると共に、貯水された水の蒸発を防止するようにも機能する。   The water collecting sheet 20 is stretched so as to cover the upper surface of the water storage tank 10, is provided in a sheet shape with a non-permeable and flexible material, and passes through a central portion where the sheet surface hangs most by its own weight. Water holes 21 are provided. The water collecting sheet 20 functions to appropriately receive rainwater and collect water, and also functions to prevent evaporation of stored water.

球体３０は、集水用シート２０上に転動自在に置かれて、自重の作用と集水用シート２０の張力による反作用を受けて常時は通水孔２１の上に位置してその通水孔２１を塞ぎ、集水用シート真上に水が溜まった際には浮くことができるようにみかけ比重が水よりも小さく設けられている。この球体３０としては、例えば、木製球、又は中空に設けられたチタンボールやステンレスボールを用いることができる。   The spherical body 30 is placed on the water collection sheet 20 so as to be freely rollable, and is always located above the water passage hole 21 due to the action of its own weight and the reaction caused by the tension of the water collection sheet 20. The apparent specific gravity is set smaller than that of water so that the hole 21 can be closed and floated when the water is collected right above the water collecting sheet. As the sphere 30, for example, a wooden sphere, or a titanium ball or a stainless ball provided in a hollow space can be used.

この球体３０が、集水用シート２０が漏斗形状やお椀形状（図１（ｂ）参照）になるように、重石となる。これによれば、集水用シート２０を、雨水を適切に受けることができる形状に保持できる共に、その集水用シート２０のバタツキを防止し、騒音の発生を防止できる。なお、球体３０が通水孔２１を塞いでいる際の状態は、シール状態でないとよい。これによれば、僅かな隙間から、集水用シート２０上に受けられた雨水が、貯水槽１０内へ流れ落ちることができる。また、大量の雨が降って、急激に集水用シート２０上に水が溜まった際には、球体３０が浮くことができるため、通水孔２１が大きく開き、雨水が貯水槽１０内へ適性に流れ落ちることができる。さらに、球体３０が、通水孔２１を塞ぐことで、ゴミの進入や蚊などの生物の侵入を防ぐこともできる。このように球体３０は、通水孔２１を自動的に開閉する弁体として作用するため、通水孔２１に係る開閉の管理が不要になる。   The spherical body 30 becomes a heavy stone so that the water collecting sheet 20 has a funnel shape or a bowl shape (see FIG. 1B). According to this, the water collecting sheet 20 can be held in a shape that can appropriately receive rainwater, and the water collecting sheet 20 can be prevented from fluttering and noise can be prevented. In addition, the state when the spherical body 30 is blocking the water passage hole 21 may not be a sealed state. According to this, rainwater received on the water collecting sheet 20 can flow down into the water storage tank 10 from a slight gap. In addition, when a large amount of rain falls and water suddenly accumulates on the water collecting sheet 20, the sphere 30 can float, so that the water passage hole 21 is opened widely and rainwater enters the water storage tank 10. Can flow down to suitability. Furthermore, since the spherical body 30 blocks the water passage hole 21, it is possible to prevent entry of garbage and invasion of organisms such as mosquitoes. Thus, since the spherical body 30 acts as a valve body that automatically opens and closes the water passage hole 21, management of opening and closing of the water passage hole 21 becomes unnecessary.

このような構成を備える雨水集水器によれば、年間降水量を好適に貯水することができ、蒸発量を極めて小さく抑えることができる。また、地面を平にして簡単な工事で設置でき、最も低コストで製作できる形態となっており、世界中で使用できる。畑、休耕田、空地、ビルの屋上、砂漠等の世界中のあらゆる場所で使用できる。   According to the rainwater collector having such a configuration, the annual precipitation can be suitably stored, and the amount of evaporation can be kept extremely small. In addition, it can be installed by simple construction with the ground level, and it can be manufactured at the lowest cost and can be used all over the world. Can be used anywhere in the world such as fields, fallow fields, open spaces, building rooftops, and deserts.

また、集水用シート２０が、貯水槽１０の上面の外側へ拡張できるように設けられ、延長シート部２２（図１（ｂ）参照）が形成されるようにしてもよい。集水用シート２０を拡張する方法としては、折り畳んであるシート材（延長シート部２２）を開いて延長する方法や、別体のシート材（延長シート部２２）を継ぎ足して延長させる方法を採用することができる。これによれば、雨水を受け止める面積を好適に拡張でき、効率的に雨水を集水できる。なお、延長シート部２２は地面に固定した支柱などで保持すればよい。   Further, the water collecting sheet 20 may be provided so as to be extended to the outside of the upper surface of the water storage tank 10, and an extension sheet portion 22 (see FIG. 1B) may be formed. As a method of expanding the water collecting sheet 20, a method of opening and extending the folded sheet material (extension sheet portion 22) or a method of extending and extending a separate sheet material (extension sheet portion 22) is adopted. can do. According to this, the area which catches rainwater can be expanded suitably, and rainwater can be collected efficiently. The extension sheet portion 22 may be held by a post fixed to the ground.

また、貯水槽１０の内部に、集水用シート２０を介して球体３０を受けることができる球体用の受け部４０が設けられていてもよい。これによれば、球体３０が常時は球体用の受け部４０によって受けられるため、集水用シート２０が必要以上に伸びることを防止できる。   In addition, a sphere receiving portion 40 that can receive the sphere 30 via the water collecting sheet 20 may be provided inside the water tank 10. According to this, since the spherical body 30 is always received by the receiving part 40 for spherical bodies, it can prevent that the sheet | seat 20 for water collection extends more than necessary.

以上、本発明につき好適な形態例を挙げて種々説明してきたが、本発明はこの形態例に限定されるものではなく、発明の精神を逸脱しない範囲内で多くの改変を施し得るのは勿論のことである。   As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
