Description

本発明は、取水開始からの所定量の初期雨水を排除する初期雨水排除手段及び初期雨水が排除された雨水を貯留する貯水部を具備する雨水収集装置に関する。   The present invention relates to an initial rainwater removing means for removing a predetermined amount of initial rainwater from the start of water intake, and a rainwater collecting apparatus including a water storage unit for storing rainwater from which initial rainwater has been removed.

従来、降雨時において、住宅に付設された雨樋を流れる雨水を収集して貯留する雨水収集装置は知られており、各種形態の雨水収集装置が提案されている。また、雨樋の雨水を収集する場合、初期の雨水（初期雨水）は、落葉，鳥糞，ゴミ，ほこり，酸性雨成分等により比較的汚れ度合が大きいため、取水開始からの所定量の初期雨水を排除する初期雨水排除手段を設けた雨水収集装置も、特開平１０−３７２５５号公報（雨水利用システム）及び特開２００１−１１５５０１号公報（雨水貯水装置）で知られている。   Conventionally, a rainwater collecting apparatus that collects and stores rainwater flowing through a gutter attached to a house during a rain is known, and various forms of rainwater collecting apparatuses have been proposed. In addition, when collecting rainwater from rain gutters, the initial rainwater (initial rainwater) has a relatively large degree of contamination due to defoliation, bird droppings, garbage, dust, acid rain components, etc., so a predetermined amount of initial water from the start of water intake A rainwater collecting apparatus provided with an initial rainwater draining means for draining rainwater is also known from Japanese Patent Application Laid-Open No. 10-37255 (rainwater utilization system) and Japanese Patent Application Laid-Open No. 2001-115501 (rainwater storage device).

前者の雨水利用システムは、雨水が流れる縦樋の途中を排水経路と集水経路とに分岐すると共に集水経路を貯水タンクに連通させ、縦樋を流れる雨水が排水経路側に流れるようにしたり集水経路側に流れたりするように切り替える切り替え板を分岐部に回動自在に設け、切り替え板の下部に排水経路側に流れる雨水を受ける雨水一時受けタンクを設け、降雨初期には縦樋を流れる雨水を排水経路側に流して雨水一時受けタンクに受けるようにすると共に雨水一時受けタンクに所定量以上の雨水が溜まったとき、その重量で切り替え板を回動させて集水経路側に雨水が流れるように切り替えるものである。   In the former rainwater utilization system, the drainage channel and the water collection channel are branched into the drainage channel where rainwater flows, and the water collection channel is connected to the water storage tank so that the rainwater flowing through the vertical channel flows to the drainage channel side. A switching plate that switches to the water collection path side is provided at the branching part so that it can rotate freely. When flowing rainwater flows to the drainage path side and is received by the rainwater temporary receiving tank, and when rainwater of a predetermined amount or more accumulates in the rainwater temporary receiving tank, the switching plate is rotated by the weight of the rainwater to the water collecting path side. Is switched to flow.

また、後者の雨水貯水装置は、上部に集水管からの雨水が導入される導入部を有し、底部に導入部より小さな開口の排水口を有して形成された、初期雨水を受け入れる受水部と、この受水部に配設された受水部に溜まる水量に応じて変位するフロート部と、このフロート部とつながって排水口を開閉するように設けられた排水口を所定水量になるまでは開放させて、初期雨水を一部は排水口から外部へ排水しながら受水部に貯溜させる弁体と、所定水量の水位に対応した受水部の側壁に形成され、所定水量になるにしたがい初期雨水に続く通常雨水を貯水槽へ導く通孔部とを設けたものである。
特開平１０−３７２５５号 特開２００１−１１５５０１号 In addition, the latter rainwater storage device has an introduction part into which rainwater from a water collecting pipe is introduced at the top, and has a drainage opening with a smaller opening than the introduction part at the bottom, receiving water for receiving initial rainwater. And a float portion that is displaced according to the amount of water accumulated in the water receiving portion disposed in the water receiving portion, and a drain port that is connected to the float portion so as to open and close the drain port has a predetermined amount of water. Is formed on the side wall of the water receiving part corresponding to the water level corresponding to the water level corresponding to the water level corresponding to the water level corresponding to the water level corresponding to the water level. Accordingly, there is provided a through hole portion for guiding normal rain water following the initial rain water to the water storage tank.

しかし、上述した従来の雨水収集装置は、次のような問題点があった。   However, the conventional rainwater collecting apparatus described above has the following problems.

第一に、取水開始からの所定量の初期雨水を排除する初期雨水排除手段は、装置本体（貯水タンクや貯水槽）とは別体となる初期雨水分離装置等の専用装置として構成し、装置本体の前段に接続するため、装置全体が大型構成になり、設置する際の省スペース性に劣るとともに、コストアップを招く要因ともなる。   First, the initial rainwater removal means for removing a predetermined amount of initial rainwater from the start of water intake is configured as a dedicated device such as an initial rainwater separator that is separate from the device main body (water tank or water tank). Since it is connected to the front stage of the main body, the entire apparatus has a large configuration, which is inferior in space saving at the time of installation and causes a cost increase.

第二に、装置本体の前段に初期雨水分離装置として接続することから、初期雨水に混入する落葉やゴミ等の異物を除去するフィルタを設けにくい。結局、初期雨水の収集時における異物が初期雨水分離装置に詰まりやすく、頻繁なメンテナンスが強いられるとともに、故障や不調の原因となる。   Secondly, since it is connected as an initial rainwater separator in the front stage of the apparatus main body, it is difficult to provide a filter for removing foreign matters such as fallen leaves and dust mixed in the initial rainwater. Eventually, foreign substances at the time of collecting initial rainwater are likely to be clogged in the initial rainwater separation device, forcing frequent maintenance and causing failures and malfunctions.

第三に、この種の雨水収集装置は、集中豪雨などに対する流水緩衝対策と資源としての雨水の有効利用の二つの側面を有しているが、専ら雨水の有効利用に重点がおかれる傾向があり、二つの側面の双方を十分に満たす観点からの十分な検討が行われているとは言い難い。   Thirdly, this type of rainwater collection device has two aspects: running water buffering measures against concentrated heavy rain and effective use of rainwater as a resource, but there is a tendency to focus exclusively on effective use of rainwater. Yes, it is hard to say that sufficient consideration has been made from the viewpoint of sufficiently satisfying both of the two aspects.

本発明は、このような背景技術に存在する課題を解決した雨水収集装置の提供を目的とするものである。   The object of the present invention is to provide a rainwater collecting apparatus that solves the problems in the background art.

When the rainwater collecting apparatus 1 is provided, the initial rainwater discharge port 4 provided at the bottom 3d of the water storage unit 3 and a predetermined volume capable of storing the initial rainwater We flowing out from the initial rainwater discharge port 4 are provided. And an initial rainwater storage trough 5 having drain holes 5h that can set a drainage flow rate smaller than the flow rate of the initial rainwater We inflow, and an initial stage after the initial rainwater We fills at least the initial rainwater storage trough 5 An initial rainwater draining means 2 having a valve mechanism 6 for closing the rainwater draining port 4 is provided.

In the rainwater We, W when the rainwater We, W flowing in passes. .., And two or more filters 11a, 11b,... Can have different meshes. Further, the valve mechanism section 6 includes a float section 12 disposed in the water storage section 3 and a valve body section 13 that closes the initial rainwater discharge port section 4 by at least the rise of the float section 12 in conjunction with the elevation of the float section 12.

図１及び図２は、雨水収集装置１の全体構成を示す。図１中、Ｐは、住宅の外壁に付設した鉛直方向の雨樋を示す。この雨樋Ｐは、所定の高さ位置で切断し、切断後の下端部は、雨水収集装置１を接続する接続口Ｐｄとする。Ｇは、雨水収集装置１を設置する設置面（地面）である。   1 and 2 show the overall configuration of the rainwater collecting apparatus 1. In FIG. 1, P shows the vertical gutter attached to the outer wall of a house. This rain gutter P is cut at a predetermined height position, and the lower end portion after cutting is a connection port Pd to which the rain water collecting device 1 is connected. G is an installation surface (ground) on which the rainwater collecting apparatus 1 is installed.

雨水収集装置１において、３は貯水部であり、基本的な構成として基礎タンク３ｏと貯留タンク３ａを備える。基礎タンク３ｏは、上端が開放されたタンク本体部２１と、このタンク本体部２１の上端を覆う着脱式の蓋部２２を備える。蓋部２２には、接続口２２ｃを設け、上述した雨樋Ｐの接続口Ｐｄと接続口２２ｃを雨水導入管２３により接続する。この雨水導入管２３には、自在に変形する蛇腹管を用いることが望ましい。なお、タンク本体部２１は、複数の脚部２４…により所定の高さ位置に支持される。   In the rainwater collecting apparatus 1, reference numeral 3 denotes a water storage unit, which includes a basic tank 3o and a storage tank 3a as a basic configuration. The basic tank 3o includes a tank body 21 having an open upper end and a detachable lid 22 that covers the upper end of the tank body 21. The lid 22 is provided with a connection port 22 c, and the connection port Pd of the rain gutter P and the connection port 22 c are connected by a rainwater introduction pipe 23. The rainwater introduction pipe 23 is desirably a bellows pipe that can be freely deformed. The tank body 21 is supported at a predetermined height by a plurality of legs 24.

一方、タンク本体部２１には、初期雨水排除手段２を設ける。図３に、初期雨水排除手段２を抽出して示す。初期雨水排除手段２は、タンク本体部２１（基礎タンク３ｏ）の底部（底面部）３ｄに設けた初期雨水排出口部４と、この初期雨水排出口部４から流出する初期雨水Ｗｅを収容可能な所定の容積を有し、かつ流入する初期雨水Ｗｅの流量よりも少ない排水流量を設定可能な排水孔５ｈ…を有する初期雨水収容桝部５と、少なくとも初期雨水収容桝部５を初期雨水Ｗｅが満たした後に初期雨水排除口部４を閉じる弁機構部６とを備えて構成する。   On the other hand, the tank body 21 is provided with initial rainwater draining means 2.

Accordingly, the initial rainwater We that has flowed in can be accommodated in the initial rainwater storage trough 5, and the initial rainwater We (rainwater W) is discharged from the drain holes 5h to a predetermined amount of drainage. In addition, setting the drainage flow rate smaller than the flow rate of the initial rainwater We flowing in through the drainage holes 5h is set according to the quantity and size of the drainage holes 5h and substantially considering the permeability to the ground G. To set.

弁機構部６は、貯水部３内に配したフロート部１２及びこのフロート部１２の昇降に連動し、少なくともフロート部１２の上昇により初期雨水排出口部４を閉じる弁体部１３を備える。この場合、底部３ｄの上面にブラケット部３３を固定し、このブラケット部３３によりレバー部３４の中間位置を支軸により回動自在に支持するとともに、レバー部３４の先端にゴムボール等の球状の弁体部１３をワイヤ材３５により吊り下げ、かつレバー部３４の後端にフロート部１２を取付ける。３６，３７は、レバー部３２の回動範囲を規制するストッパ部であり、ストッパ部３６は、フロート部１２の上昇変位を規制するとともに、ストッパ部３７は、フロート部１２の下降変位を規制する。このような弁機構部６を用いることにより、弁機構部６を比較的簡易な構造により構成できるとともに、弁機構部６を確実に機能させることができる利点がある。   The valve mechanism unit 6 includes a float unit 12 disposed in the water storage unit 3 and a valve body unit 13 that closes the initial rainwater discharge port unit 4 by at least ascending the float unit 12 in conjunction with the elevation of the float unit 12. In this case, the bracket portion 33 is fixed to the upper surface of the bottom portion 3d, and the intermediate position of the lever portion 34 is supported by the bracket portion 33 so as to be rotatable by a support shaft, and a spherical ball such as a rubber ball is provided at the tip of the lever portion 34. The valve body portion 13 is suspended by the wire material 35 and the float portion 12 is attached to the rear end of the lever portion 34. Reference numerals 36 and 37 denote stopper portions that restrict the rotation range of the lever portion 32. The stopper portion 36 restricts upward displacement of the float portion 12, and the stopper portion 37 restricts downward displacement of the float portion 12. . By using such a valve mechanism section 6, there is an advantage that the valve mechanism section 6 can be configured with a relatively simple structure and the valve mechanism section 6 can function reliably.

これにより、弁機構部６は、降雨がなければ、図３に仮想線で示すように、フロート部１２が自重で下降するため、弁体部１３は上昇し、初期雨水排出口部４を開いた状態に維持する。これに対して、降雨が開始し、初期雨水Ｗｅが初期雨水収容桝部５を満たし、さらに、基礎タンク３ｏ内において雨水Ｗの水位が上昇すれば、図３に実線で示すように、フロート部１２が浮力で上昇するため、弁体部１３は下降し、弁座部２６に当接して初期雨水排除口部４を閉じることができる。   As a result, if there is no rain, the valve mechanism unit 6 moves down by its own weight as shown by a virtual line in FIG. 3, so that the valve body unit 13 rises and opens the initial rainwater discharge port 4. To maintain the state. On the other hand, if the rain starts, the initial rainwater We fills the initial rainwater storage trough 5 and the water level of the rainwater W rises in the foundation tank 3o, the float part is shown in FIG. Since 12 rises by buoyancy, the valve body portion 13 is lowered, and can contact the valve seat portion 26 to close the initial rainwater drain port 4.

他方、基礎タンク３ｏの内部空間上部には、流入する雨水Ｗｅ，Ｗを通過させることにより当該雨水Ｗｅ，Ｗ中の異物Ｆｘ…を除去するための着脱可能な三つのフィルタ１１ａ，１１ｂ，１１ｃを配設する。図５に、フィルタ１１ａ…を抽出して示す。各フィルタ１１ａ…は、図２に現れる矩形のフレーム４１…を有し、各フレーム４１…にネット４２ａ，４２ｂ，４２ｃを取付けて構成する。各ネット４２ａ，４２ｂ，４２ｃは、それぞれ異なるメッシュを設定し、最上部のフィルタ１１ａは、比較的大きいメッシュ（粗目）のネット４２ａを使用し、最下部のフィルタ１１ｃは、比較的小さいメッシュ（細目）のネット４２ｃを使用し、中間のフィルタ１１ｂは、ネット４２ａと４２ｃの中間のメッシュ（中目）を有するネット４２ｂを使用する。各フィルタ１１ａ…をセットするに際しては、基礎タンク３ｏの内面に、支持プレート４３を取付け、この支持プレート４３の上に各フィルタ１１ｃ…を順番に重ねてセットする。   On the other hand, in the upper part of the internal space of the basic tank 3o, three detachable filters 11a, 11b, 11c for removing the foreign substances Fx ... in the rainwater We, W by passing the inflowing rainwater We, W are provided. Arrange. FIG. 5 shows the extracted filters 11a. Each filter 11a has a rectangular frame 41 appearing in FIG. 2, and is constructed by attaching nets 42a, 42b, 42c to each frame 41. Each net 42a, 42b, 42c has a different mesh, the uppermost filter 11a uses a relatively large mesh (coarse) net 42a, and the lowermost filter 11c uses a relatively small mesh (fine mesh). ) And the intermediate filter 11b uses a net 42b having a mesh (medium mesh) between the nets 42a and 42c. When the filters 11a are set, a support plate 43 is attached to the inner surface of the basic tank 3o, and the filters 11c are sequentially stacked on the support plate 43 and set.

したがって、フィルタ１１ａ…は、任意の数量及び種別を選定できるとともに、タンク本体部２１の上端から取出可能なため、清掃やメンテナンスを容易に行うことができる。また、各フィルタ１１ａ，１１ｂ…にそれぞれ異なるメッシュを設定するため、フィルタ１１ａにより大ゴミＦｘを、フィルタ１１ｂにより中ゴミＦｍを、フィルタ１１ｃにより小ゴミＦｓをそれぞれ除去できるなど、雨水Ｗｅ，Ｗに混入する大小様々な異物Ｆｘ…を有効かつ確実に除去できる利点がある。   Therefore, the filters 11a can be selected in any quantity and type, and can be taken out from the upper end of the tank main body 21, so that cleaning and maintenance can be easily performed. Further, since different meshes are set for the filters 11a, 11b, etc., the filter 11a can remove large dust Fx, the filter 11b can remove medium dust Fm, and the filter 11c can remove small dust Fs. There is an advantage that various foreign substances Fx... Mixed can be effectively and reliably removed.

さらに、基礎タンク３ｏの側面には、溢れた雨水Ｗを流出させる流出口（接続口）を兼ねるオーバフロー口３ｏｕを設ける。このオーバフロー口３ｏｕは、最下部のフィルタ１１ｃの下方であってその近傍位置を選定する。   Further, an overflow port 3ou that also serves as an outlet (connection port) through which overflowing rainwater W flows out is provided on the side surface of the basic tank 3o. The overflow port 3ou is located below the lowermost filter 11c and in the vicinity thereof.

一方、基礎タンク３ｏに隣接して貯留タンク３ａを設置する。貯留タンク３ａは、上端が開放されたタンク本体部５１と、このタンク本体部５１の上端を覆う着脱式の蓋部５２を備える。タンク本体部５１における対向する一対の側面部の上部位置には、それぞれ接続口３ａｉと３ａｏを設け、この接続口３ａｉと基礎タンク３ｏのオーバフロー口３ｏｕを接続管５４により接続する。この接続管５４には自在に変形する蛇腹管を用いることが望ましい。また、接続口３ａｏはキャップ５５により閉塞する。なお、タンク本体部５１は、複数の脚部５３…により所定の高さ位置に支持される。   On the other hand, the storage tank 3a is installed adjacent to the basic tank 3o. The storage tank 3 a includes a tank main body 51 having an open upper end and a detachable lid 52 that covers the upper end of the tank main body 51. Connection ports 3ai and 3ao are provided at the upper positions of a pair of opposing side surface portions in the tank body 51, and the connection port 3ai and the overflow port 3ou of the basic tank 3o are connected by a connection pipe 54. It is desirable to use a bellows tube that can be freely deformed as the connection tube 54. Further, the connection port 3ao is closed by the cap 55. The tank body 51 is supported at a predetermined height by a plurality of legs 53.

図１は、一つの貯留タンク３ａを利用する場合を示すが、複数の貯留タンク３ａ，３ｂ…を利用する場合には、図６に示すように、キャップ５５を最後部に連結する貯留タンク３ｂの接続口３ｂｏに装着するとともに、貯留タンク３ａの接続口３ａｏと貯留タンク３ｂの接続口３ｂｉを接続管５６により接続すればよい。このように、貯留タンク３ａ…に、接続口３ａｉ，３ａｏ…を介して連結可能に構成した二以上の貯留タンク３ａ，３ｂ…を用いれば、貯留タンク３ａ…の貯留能力を設置場所の状態（屋根面積等）に応じて容易かつ柔軟に設定できる利点がある。   FIG. 1 shows the case where one storage tank 3a is used. However, when a plurality of storage tanks 3a, 3b... Are used, the storage tank 3b connecting the cap 55 to the rearmost portion as shown in FIG. The connection port 3bo is connected to the connection port 3ao of the storage tank 3a and the connection port 3bi of the storage tank 3b. As described above, if two or more storage tanks 3a, 3b,... Configured to be connectable to the storage tanks 3a through the connection ports 3ai, 3ao,... Are used, the storage capacity of the storage tanks 3a. There is an advantage that it can be easily and flexibly set according to the roof area.

また、接続口３ａｉ（３ｂｉも同じ）には、図４に示すような浄水手段１５を付設することができる。浄水手段１５は、貯留タンク３ａに流入する雨水Ｗが浄水手段１５を通過できるように接続口３ａｉを利用して取付け、雨水Ｗの流水経路の一部を構成する。浄水手段１５は、ネットを付設した流入口６１ｉとネットを付設した流出口６１ｏを有する流路ボックス６１を備え、この流路ボックス６１の内部に、活性炭等の浄水材１６を収容して構成する。これにより、接続口３ａｉから流入する雨水Ｗは、矢印Ｄｉの経路で流路ボックス６１の内部を通過し、この際、浄水材１６により浄化（浄水）が行われる。その他、タンク本体部５１の前面部の下部には、蛇口５７を付設するとともに、タンク本体部５１の内部には、上端にネットを付設したオーバフロー口５８ｎを有する排水管５８を起設し、排水管５８の下端排出口はタンク本体部５１における底部の下方に露出させる。   Moreover, the water purification means 15 as shown in FIG. 4 can be attached to the connection port 3ai (3bi is also the same). The water purification means 15 is attached using the connection port 3ai so that the rainwater W flowing into the storage tank 3a can pass through the water purification means 15, and constitutes a part of the flow path of the rainwater W. The water purification means 15 includes a flow path box 61 having an inlet 61i with a net attached and an outlet 61o with a net attached, and the water purification material 16 such as activated carbon is accommodated in the flow path box 61. . Thereby, the rainwater W flowing in from the connection port 3ai passes through the inside of the flow path box 61 along the path of the arrow Di, and at this time, purification (purified water) is performed by the water purification material 16. In addition, a faucet 57 is provided at the lower part of the front surface of the tank main body 51, and a drain pipe 58 having an overflow port 58n with a net attached to the upper end is provided inside the tank main body 51 for drainage. The lower end discharge port of the pipe 58 is exposed below the bottom of the tank body 51.

次に、本実施形態に係る雨水収集装置１の作用（機能）について、図７に示すフローチャートを参照して説明する。   Next, the operation (function) of the rainwater collecting apparatus 1 according to the present embodiment will be described with reference to the flowchart shown in FIG.

今、天候が晴れている状態から雨が降り始めた状態を想定する（ステップＳ１）。住宅における屋根上の雨水は、図１に示す鉛直の雨樋Ｐを流れ落ち、雨水導入管２３を通って基礎タンク３ｏの内部に流入する（ステップＳ２）。この際、雨が降り始めてから基礎タンク３ｏに最初に流入する雨水は初期雨水Ｗｅとなる。基礎タンク３ｏに流入した初期雨水Ｗｅは、まず、三つのフィルタ１１ａ，１１ｂ，１１ｃを通過する。初期雨水Ｗｅは、落葉，鳥糞，ゴミ，ほこり，酸性雨成分等により比較的汚れ度合が大きいため、各フィルタ１１ａ，１１ｂ，１１ｃにより異物Ｆｘ…の除去が行われる（ステップＳ３）。この場合、図５に示すように、最初に、粗目のネット４２ａを有するフィルタ１１ａにより、落葉等の大ゴミＦｘが除去され、この後、中目のネット４２ｂを有するフィルタ１１ｂにより、木の実等の中ゴミＦｍが除去され、この後、細目のネット４２ｃを有するフィルタ１１ｃにより、砂等の小ゴミＦｓが除去される。   Now, assume a state in which rain starts from a sunny weather (step S1). The rainwater on the roof in the house flows down the vertical rain gutter P shown in FIG. 1 and flows into the inside of the basic tank 3o through the rainwater introduction pipe 23 (step S2). At this time, the rainwater first flowing into the basic tank 3o after the rain starts is the initial rainwater We. Initial rainwater We flowing into the foundation tank 3o first passes through the three filters 11a, 11b, and 11c. Since the initial rainwater We has a relatively high degree of contamination due to leaf litter, bird droppings, dust, dust, acid rain components, etc., the foreign substances Fx... Are removed by the filters 11a, 11b, and 11c (step S3). In this case, as shown in FIG. 5, first, large dust Fx such as fallen leaves is removed by the filter 11a having the coarse net 42a, and thereafter, the filter 11b having the middle net 42b is used to remove the nuts and the like. The medium dust Fm is removed, and then the small dust Fs such as sand is removed by the filter 11c having the fine net 42c.

そして、各フィルタ１１ａ…を通過した初期雨水Ｗｅは、基礎タンク３ｏの底部３ｄに落下する。この際、弁機構部６は開いた状態、即ち、弁体部１３は、図３において仮想線で示す位置に上昇しているため、初期雨水Ｗｅは、初期雨水排除口部４を通って初期雨水収容桝部５に流入する（ステップＳ４）。初期雨水収容桝部５は、所定の排水流量により外部に排水可能に設置されており、初期雨水収容桝部５に流入する初期雨水Ｗｅの流量が排水流量よりも少ない状態にあれば、流入した初期雨水Ｗｅは、初期雨水収容桝部５に貯留されることなく全て外部に排出されるとともに、流入する初期雨水Ｗｅの流量が排水流量よりも多い状態になれば、多い分だけ初期雨水収容桝部５に貯留される（ステップＳ５，Ｓ６）。初期雨水Ｗｅは、通常、降雨開始から徐々に多くなるため、最初は、早い時間に地面Ｇに浸透し、ある程度の流量に達すれば、初期雨水収容桝部５に貯留される。したがって、汚れた初期雨水Ｗｅの排除が早い時間に確実に行われる。また、初期雨水Ｗｅの流入する流量が多くなり、初期雨水Ｗｅが初期雨水収容桝部５を満たせば、さらに、基礎タンク３ｏに貯留し始める。これにより、フロート部１２は、図３に実線で示す位置まで浮力により徐々に上昇するとともに、他方、弁体部１３が弁座部２６に当接し、初期雨水排除口部４が閉塞されることにより弁機構部６は閉じた状態になる（ステップＳ７）。   And the initial rain water We which passed each filter 11a ... falls to the bottom part 3d of the basic tank 3o. At this time, since the valve mechanism section 6 is in an open state, that is, the valve body section 13 is raised to the position indicated by the phantom line in FIG. 3, the initial rainwater We passes through the initial rainwater drain port 4 to the initial stage. It flows into the rainwater storage trough 5 (step S4). The initial rainwater storage trough 5 is installed so that it can be drained to the outside with a predetermined drainage flow rate. If the initial rainwater We flowed into the initial rainwater storage trough 5 is less than the drainage flow rate, it has flowed in. The initial rainwater We is discharged to the outside without being stored in the initial rainwater storage trough 5, and if the flow rate of the inflowing initial rainwater We is greater than the drainage flow rate, the initial rainwater storage trough is increased by a large amount. Stored in the unit 5 (steps S5 and S6). Since the initial rainwater We normally increases gradually from the start of rainfall, first, it penetrates the ground G at an early time and is stored in the initial rainwater storage trough 5 when it reaches a certain flow rate. Accordingly, the dirty initial rainwater We is reliably removed at an early time. Further, when the initial rainwater We flows in and the initial rainwater We fills the initial rainwater storage trough 5, the initial rainwater We starts to be stored in the basic tank 3 o. As a result, the float portion 12 gradually rises to the position indicated by the solid line in FIG. 3 due to buoyancy, and on the other hand, the valve body portion 13 comes into contact with the valve seat portion 26 and the initial rainwater drain port portion 4 is closed. Thus, the valve mechanism 6 is closed (step S7).

弁機構部６が閉じた状態になることにより、基礎タンク３ｏに流入した雨水Ｗは、タンク本体部２１に貯留される（ステップＳ８）。そして、タンク本体部２１内の雨水Ｗが、溢れレベルとなるオーバフロー口３ｏｕの高さ位置まで満たせば、雨水Ｗはオーバフロー口３ｏｕから流出し、接続管５４を通って流路ボックス６１に流入する。雨水Ｗは流路ボックス６１内を矢印Ｄｉ（図４）の経路により流れ、浄水材１６により浄化された後、貯留タンク３ａの内部に貯留される（ステップＳ９，Ｓ１０，Ｓ１１）。このように、貯留タンク３ａは、基礎タンク３ｏに収容された雨水Ｗのうち、奇麗な上澄み水のみをに貯留できるため、雨水Ｗに対する用途拡大や有効利用に寄与できる。また、雨水Ｗは、流路ボックス６１内の浄水材１６（浄水手段１５）により浄化されるため、貯留タンク３ａに貯留する雨水Ｗの更なる浄化に寄与できる。   When the valve mechanism 6 is closed, the rainwater W that has flowed into the basic tank 3o is stored in the tank body 21 (step S8). And if the rain water W in the tank main body 21 fills up to the height position of the overflow port 3ou at the overflow level, the rain water W flows out from the overflow port 3ou and flows into the flow path box 61 through the connection pipe 54. . The rainwater W flows in the flow path box 61 along the path indicated by the arrow Di (FIG. 4), is purified by the water purification material 16, and is stored in the storage tank 3a (steps S9, S10, S11). Thus, since the storage tank 3a can store only the clean supernatant water among the rainwater W accommodated in the basic tank 3o, it can contribute to the use expansion and effective use with respect to the rainwater W. Moreover, since the rainwater W is purified by the water purification material 16 (water purification means 15) in the flow path box 61, it can contribute to the further purification of the rainwater W stored in the storage tank 3a.

一方、貯留タンク３ａに貯留した雨水Ｗは、蛇口５７から外部に供給し、利用できるとともに、貯留タンク３ａに満杯になった雨水Ｗは、排水管５８を通して外部に排出される。他方、雨が止めば、基礎タンク３ｏへの雨水Ｗの流入が停止し、基礎タンク３ｏに対する追加の貯留は無くなる。この場合、基礎タンク３ｏ内には雨水Ｗが残留するが、底部３ｄには通水部１４が設けられているため、基礎タンク３ｏ内の残留した雨水Ｗは、少しずつ通水部１４を通して初期雨水収容桝部５に流入した後、地面Ｇに浸透する。この結果、最終的には、基礎タンク３ｏ及び初期雨水収容桝部５の内部は空の状態になり、弁機構部６は開いた状態となる（ステップＳ１２）。   On the other hand, the rainwater W stored in the storage tank 3 a can be supplied to the outside from the faucet 57 and can be used, and the rainwater W that is full in the storage tank 3 a is discharged to the outside through the drain pipe 58. On the other hand, if the rain stops, the inflow of the rainwater W to the basic tank 3o is stopped, and additional storage in the basic tank 3o is eliminated. In this case, the rainwater W remains in the foundation tank 3o, but the bottom portion 3d is provided with the water passage portion 14, so that the remaining rainwater W in the foundation tank 3o is gradually passed through the water passage portion 14 in the initial stage. After flowing into the rainwater storage trough 5, it penetrates into the ground G. As a result, finally, the inside of the basic tank 3o and the initial rainwater storage trough 5 is empty, and the valve mechanism 6 is opened (step S12).

このように、本実施形態に係る雨水収集装置１によれば、初期雨水排除手段２を、貯水部３の内部に一体的に設けることができるため、別体に構成する専用装置が不要になる。したがって、収集装置１全体の小型化を実現でき、設置する際の省スペース性を高めることができるとともに、低コスト化に貢献できる。また、貯水部３の底部３ｄに初期雨水排除手段２を設けるため、この初期雨水排除手段２に、貯水部３に付設するフィルタ１１ａ…を通過した初期雨水Ｗｅ、即ち、落葉やゴミ等の異物Ｆｘ…の除去された初期雨水Ｗｅを供給することができる。したがって、初期雨水Ｗｅの流入時における異物Ｆｘ…が初期雨水排除手段２に詰まるなどの不具合を回避でき、メンテナンスの容易化を図れるとともに、故障や不調を防止できる。   As described above, according to the rainwater collecting apparatus 1 according to the present embodiment, the initial rainwater draining means 2 can be integrally provided inside the water storage unit 3, so that a dedicated device configured separately is not necessary. . Therefore, it is possible to reduce the size of the entire collection device 1, and to improve the space saving at the time of installation, and to contribute to cost reduction. Further, since the initial rainwater draining means 2 is provided at the bottom 3d of the water storage section 3, the initial rainwater Wet that has passed through the filter 11a attached to the water storage section 3 to the initial rainwater draining means 2, that is, foreign matter such as fallen leaves and dust. The initial rainwater We from which Fx... Has been removed can be supplied. Therefore, it is possible to avoid problems such as the clogging of the foreign matter Fx at the inflow of the initial rainwater We in the initial rainwater draining means 2, thereby facilitating maintenance and preventing failure and malfunction.

次に、本発明に係る雨水収集装置１の変更実施形態について、図８及び図９を参照して説明する。   Next, a modified embodiment of the rainwater collecting apparatus 1 according to the present invention will be described with reference to FIGS. 8 and 9.

図８に示す雨水収集装置１は、貯水部３として基礎タンク３ｏのみを使用し、他の貯留タンク３ａ…を使用しない変更実施形態を示す。この場合、通水部１４を設けず、基礎タンク３ｏに貯留（残留）した雨水Ｗを利用する。したがって、オーバフロー口３ｏｕには排水管７１を接続し、溢れた雨水Ｗを外部に排出するとともに、基礎タンク３ｏのタンク本体２１の下部に蛇口７２を設ける。なお、弁機構部６には、プレート状の弁体部１３を用いた場合を例示する。   The rainwater collecting apparatus 1 shown in FIG. 8 shows a modified embodiment in which only the basic tank 3o is used as the water storage unit 3 and the other storage tanks 3a are not used. In this case, the rain water W stored (residual) in the basic tank 3o is used without providing the water flow section 14. Accordingly, a drain pipe 71 is connected to the overflow port 3ou to discharge the overflowing rainwater W to the outside, and a faucet 72 is provided below the tank body 21 of the basic tank 3o. In addition, the case where the plate-shaped valve body part 13 is used for the valve mechanism part 6 is illustrated.

図９に示す雨水収集装置１は、図１と同様、貯水部３として基礎タンク３ｏと貯留タンク３ａ…を使用するとともに、通水部１４の通水量を調整できるように構成した変更実施形態を示す。この場合、弁機構部６を構成するプレート状の弁体部１３に通水口８１を形成するとともに、支軸ネジ８３を介して調整用サブプレート８２を取付けた。したがって、支軸ネジ８３を締緩することにより調整用サブプレート８２を回動変位させれば、通水口８１を完全に閉塞する位置から全開する位置まで、通水口８１の開口面積を任意に設定できる。なお、図８及び図９において、図１〜図６と同一部分には同一符号を付してその構成を明確にした。   The rainwater collecting apparatus 1 shown in FIG. 9 uses a basic tank 3o and a storage tank 3a as the water storage unit 3 as in FIG. 1, and has a modified embodiment configured so that the water flow rate of the water flow unit 14 can be adjusted. Show. In this case, the water flow port 81 was formed in the plate-like valve body portion 13 constituting the valve mechanism portion 6, and the adjustment sub-plate 82 was attached via the support shaft screw 83. Therefore, if the adjustment sub-plate 82 is rotationally displaced by tightening or loosening the support shaft screw 83, the opening area of the water flow port 81 is arbitrarily set from the position where the water flow port 81 is completely closed to the position where the water flow port 81 is fully opened. it can. 8 and 9, the same components as those in FIGS. 1 to 6 are denoted by the same reference numerals to clarify the configuration.

以上、最良の実施形態について詳細に説明したが、本発明は、このような実施形態に限定されるものではなく、細部の構成，形状，素材，数量等において、本発明の要旨を逸脱しない範囲で、任意に変更，追加，削除することができる。例えば、初期雨水収容桝部５は、地面Ｇに埋設する場合を示したが、必ずしも埋設することを要しない。したがって、タンク本体部２１を上下二段構成とし、下段部分を初期雨水収容桝部５として構成することもできる。また、必要により、加熱手段，冷却手段，ポンプ手段等の各種補助機器（周辺機器）を付設することも可能である。   Although the best embodiment has been described in detail above, the present invention is not limited to such an embodiment, and the scope of the present invention is not deviated from the gist of the present invention in the detailed configuration, shape, material, quantity, and the like. It can be changed, added, or deleted arbitrarily. For example, although the initial rainwater storage trough 5 has been shown to be embedded in the ground G, it is not necessarily required to embed. Therefore, the tank main body 21 can be configured as a two-stage structure, and the lower part can be configured as the initial rainwater storage trough 5. If necessary, various auxiliary devices (peripheral devices) such as a heating device, a cooling device, and a pump device can be attached.
