【発明の詳細な説明】
本発明は水耕槽へ一定水頭で給水するもので水
耕槽の個数に係わらずそれぞれに一定流量の給水
を行うことを目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention supplies water to hydroponic tanks at a constant head of water, and aims to supply water at a constant flow rate to each hydroponic tank regardless of the number of the tanks.
以下、実施例について説明する。 Examples will be described below.
１は水耕槽、２は排水管、３は排水タンク、す
なわち、下位タンク、Ｐはポンプ、４は送水管、
５は給水タンク、すなわち上位タンク、６は水耕
槽１への給水管である。給水管６はタンク５の底
部近くにその一端を設け、他端より水耕槽１にサ
イホンの原理で給水する。 1 is a hydroponic tank, 2 is a drain pipe, 3 is a drain tank, that is, a lower tank, P is a pump, 4 is a water pipe,
5 is a water supply tank, that is, an upper tank; 6 is a water supply pipe to the hydroponic tank 1; One end of the water supply pipe 6 is provided near the bottom of the tank 5, and water is supplied to the hydroponic tank 1 from the other end using the siphon principle.
７は溢水管でタンク５の上部の適所にその取出
口８が設けられている。 Reference numeral 7 denotes an overflow pipe, and its outlet 8 is provided at a suitable location above the tank 5.
したがつて、溢水管７よりタンク５の水が溢水
するに十分な程度の送水量をポンプｐによつて送
水するときには一定水頭ｈ以上は溢水管７により
タンク３に水が戻されて常にタンク５の水頭ｈは
一定に保たれてその最高水位面９は一定である。 Therefore, when the pump p sends enough water to cause the tank 5 to overflow from the overflow pipe 7, water is returned to the tank 3 through the overflow pipe 7 when the water head exceeds a certain level h, and the water is always kept in the tank. The water head h of 5 is kept constant, and its highest water level surface 9 is constant.
そこで、給水管６の出口と最高水位９との落差
をＨとすると
Ｄ√2（Ｄは管６の断面積）
の一定流量の給水が水耕槽１に供給される。な
お、給水量を加減にするには給水管６を傾けてＨ
を変えればよい。 Therefore, assuming that the head difference between the outlet of the water supply pipe 6 and the highest water level 9 is H, a constant flow rate of D√2 (D is the cross-sectional area of the pipe 6) is supplied to the hydroponic tank 1. In addition, to adjust the amount of water supplied, tilt the water supply pipe 6 and
All you have to do is change.
そして、排水管２により排水量に対応して、そ
れを補うべく給水管６よりの前記供給水量を設定
すれば水耕槽１の水頭は常に所定の一定値に保つ
ことができる。 The water head of the hydroponic tank 1 can always be maintained at a predetermined constant value by setting the amount of water supplied from the water supply pipe 6 to compensate for the amount of water drained by the drain pipe 2.
なお、この場合、水耕槽において育成される野
菜の吸水量、水耕槽において蒸発する水分量など
を考慮して前記供給水量を決定する。 In this case, the amount of water to be supplied is determined in consideration of the water absorption amount of vegetables grown in the hydroponic tank, the amount of water evaporated in the hydroponic tank, and the like.
このようにして給水管６の出口と最高水位９と
の落差Ｈによつて水耕槽１に一定流量が給水され
る。 In this way, a constant flow rate of water is supplied to the hydroponic tank 1 due to the head difference H between the outlet of the water supply pipe 6 and the highest water level 9.
水耕槽が多数あるときは前記給水管６を並列し
てタンク５に設ければそれぞれの水耕槽にそれぞ
れの給水管により一定流量の水が給水される。 When there are a large number of hydroponic tanks, if the water supply pipes 6 are arranged in parallel in the tanks 5, a constant flow rate of water can be supplied to each of the hydroponic tanks through the respective water supply pipes.
なお、タンク５の最高水位面９の位置を変える
ためには第２図ａ，ｂのように溢水の取出口８を
タンク５に適所に設けて、コツク付きの栓１０を
設けて、その所要の栓１０とゴム管１１をはめて
溢水管とすればよい。 In addition, in order to change the position of the highest water level surface 9 of the tank 5, as shown in FIGS. The plug 10 and the rubber pipe 11 may be fitted to form an overflow pipe.
また、連続的に最高水位面を変えるには第３図
ａ，ｂに示すようにタンク５の底部より分岐管１
２を出して、その根部１３を中心として分岐管１
２を回動できるようにすればよい。 In addition, in order to continuously change the highest water level, a branch pipe 1 is connected from the bottom of the tank 5 as shown in Figure 3a and b.
2 and branch pipe 1 around its root 13.
2 should be able to rotate.
本発明は以上のように、上位タンク５に溢水管
を設けて上位タンクの水位を一定にするととも
に、タンク５よりサイホンの原理で水耕槽に給水
するので、上位タンク５の水頭は一定となり、水
耕槽の水頭も所定の値に保つことができる効果が
ある。 As described above, the present invention provides an overflow pipe in the upper tank 5 to keep the water level in the upper tank constant, and also supplies water from the tank 5 to the hydroponic tank using the siphon principle, so the water head in the upper tank 5 remains constant. This has the effect of keeping the water head of the hydroponic tank at a predetermined value.
