Description

本発明は、屋内外環境に応じた最適な自動潅水管理を行うための間歇型補水器に関する。   The present invention relates to an intermittent rehydrator for performing optimal automatic irrigation management according to indoor and outdoor environments.

従来から植物栽培による環境改善が提案されていたが、特に、厳しい環境にある屋上或いは壁面緑化は、植物本来のCOの固定化及び蒸散作用による気化熱で屋上の気温上昇を抑制することから、都市部のヒートアイランド現象の緩和対策として全国的に注目を集めている。このため、屋上緑化や壁面緑化のさまざまな発明が提案されている。特に、日照により乾燥しやすい屋上、壁面や屋根部に対する潅水や、保水培地に関してさまざまな提案がなされてきた。 Conventionally, environmental improvement by plant cultivation has been proposed, but in particular, rooftop or wall greening in harsh environments suppresses the temperature rise on the rooftop by the heat of vaporization due to the fixation and transpiration of the plant's original CO 2. It is receiving nationwide attention as a measure to mitigate the heat island phenomenon in urban areas. For this reason, various inventions of rooftop greening and wall greening have been proposed. In particular, various proposals have been made for watering the roof, walls and roof, which are easily dried by sunlight, and for a water retention medium.

従来の潅水システムは、給水・集水ポンプや、開閉電磁栓を電気的に制御し、特に、給水は、予め設定した一定時間ごとに作動させるものであった。   The conventional irrigation system electrically controls a water supply / collection pump and an opening / closing electromagnetic plug, and in particular, water supply is operated at predetermined time intervals.

植物の生育環境は、季節及びその日の天候により大きな違いがあり、また、植生された植物が、芽が出た状態から繁茂した状態までの生育状況に応じて潅水の消費量も大きく異なる。さらに、建物屋上にあっては、その環境の変化は地面に接した環境より大きく変化する。このため、屋上緑化においては、従来の一定時間ごとの自動給水システムでは、過剰給水や給水不足をきたし、本来の植物成長に適した給水を行うことがなされていなかった。このため、屋上緑化の問題解決には潅水管理が重要な課題となっていた。   The growth environment of the plant greatly differs depending on the season and the weather of the day, and the amount of irrigation water greatly varies depending on the growth condition of the vegetated plant from the state of buds to the state of prosperity. Furthermore, on the rooftop of a building, the environment changes more greatly than the environment in contact with the ground. For this reason, in the rooftop greening, the conventional automatic water supply system at regular intervals causes excessive or insufficient water supply, and water supply suitable for plant growth has not been performed. For this reason, irrigation management has been an important issue in solving the problem of rooftop greening.

本発明者らが提案した特許文献1は、植物の育成鉢やプランターへの給水調節可能な水位調節装置と、その水位調節装置を用いた水受け器及びプランターについて開示している。   Patent Document 1 proposed by the present inventors discloses a water level adjusting device capable of adjusting water supply to a growing pot of a plant or a planter, and a water receiver and a planter using the water level adjusting device.

図7は、特許文献1の水位調節装置1の構造を示す断面図である。水位調節装置1は、底面が開放されたケース10の上壁に空気孔17を有し、水位の上昇により浮き上がる第1の浮き20が、その上下により通気用栓24が空気孔17を開閉するように取り付けられ、ケース10内に水位の変化で上下する第2の浮き30が給水パイプと接続される注水口16を開閉するように設けられた構造である。この水位調節装置1は、潅水開始水位になると、第2の浮き30が注水開始の傾き線に示すように傾き、注水口16を開けて注水させ、最高水位に達したとき、注水口16aを閉じる。このとき第2の浮き30は水位により浮き上がり注水栓を閉じた状態となり、潅水された植物が給水を吸い上げ消費するに伴い水位が低下したとき、第1の浮き20が下がり、空気孔17が塞がれたケース10内は、減圧状態となり第2の浮き30が水位と共に下がることを抑止する。水位が、ケース10の側壁に設けられた通気溝18の高さ(潅水開始水位)以下に低下したとき、通気溝18から流入する空気によりケース10内の減圧状態が解かれ、第2の浮き30が注水開始の傾き位置まで傾き注水が開始される。   FIG. 7 is a cross-sectional view showing the structure of the water level adjusting device 1 of Patent Document 1. The water level adjusting device 1 has an air hole 17 in an upper wall of the case 10 having an open bottom surface, and a first float 20 which rises due to a rise in the water level opens and closes the air hole 17 with a ventilation plug 24 due to its up and down movement. And a second float 30 that rises and falls according to a change in water level in the case 10 is provided so as to open and close the water inlet 16 connected to the water supply pipe. When the water level adjustment device 1 reaches the irrigation start water level, the second float 30 tilts as shown by the slope line of the start of water injection, opens the water injection port 16 to inject water, and when the water level reaches the maximum water level, the water injection port 16a is closed. close. At this time, the second float 30 rises due to the water level and the water tap is closed, and when the water level drops as the irrigated plant draws up and consumes the water supply, the first float 20 drops and the air hole 17 is closed. The inside of the detached case 10 is in a reduced pressure state, and the second float 30 is prevented from falling with the water level. When the water level falls below the height of the ventilation groove 18 provided on the side wall of the case 10 (irrigation start water level), the pressure in the case 10 is released by the air flowing from the ventilation groove 18 and the second floating 30 is tilted to the tilt position at the start of water injection to start water injection.

この水位調節装置1を、水受け器の底部に設けて上部の貯水タンクと連結することにすれば、電気制御やポンプなどの動力を用いることなく、植物の水消費にあわせて、間歇的に潅水を行うことができる。水受け器内に載置した植木鉢の植物が、その季節、天候に応じて水消費を行い、完全に消費してから潅水を行うことができる。この繰り返しは、植栽土壌に、水と空気を交互に供給することとなり、土壌の活性化と植物の生育条件が理想的とすることができた。このため、屋上や壁面緑化においても、潅水管理に適用することが望まれていた。   If this water level adjusting device 1 is provided at the bottom of the water receiver and is connected to the upper water storage tank, the power can be intermittently adjusted according to the water consumption of the plant without using power such as electric control or a pump. Irrigation can be performed. The plants in the flower pots placed in the water receiver consume water according to the season and weather, and can be completely consumed before watering. This repetition resulted in alternate supply of water and air to the planting soil, and the soil activation and plant growth conditions could be made ideal. For this reason, it has been desired to apply the present invention to irrigation management even on rooftops and wall greening.

この発明の水位調節装置1の適用にあたり、屋根上や壁面のメンテナンスが困難な場所で長期間の運用に当たり故障がないことが求められ、また、壁面などに取り付けられる狭い植栽容器に収容可能で、信頼性が高い間歇型補水器が求められていた。しかしながら、水位を感知する第1浮き、第2浮きの容積から小型化が難しく、第2浮きの底面が開放していることから温度、気圧の変動による動作水位のばらつきがおきる問題があった。   In applying the water level adjusting device 1 of the present invention, it is required that there is no failure in long-term operation on a roof or a place where maintenance of a wall is difficult, and it can be accommodated in a narrow planting container attached to a wall or the like. Therefore, a highly reliable intermittent rehydrator was required. However, there is a problem that it is difficult to reduce the size of the first float and the second float, which sense the water level, and that the operating water level varies due to fluctuations in temperature and atmospheric pressure because the bottom surface of the second float is open.

この問題を解決するために、本発明者らが提案した特許文献2は、第2浮き部を発泡合成樹脂の浮力体とした。しかしながら、まれではあるが発泡合成樹脂の発泡部分に水が浸入して、第2浮き部の浮力が小さくなることがあった。   In order to solve this problem, in Patent Document 2 proposed by the present inventors, the second floating portion is a buoyant body made of a foamed synthetic resin. However, although rare, water may enter the foamed portion of the foamed synthetic resin, and the buoyancy of the second floating portion may be reduced.

An embodiment of an intermittent rehydrator according to the present invention will be described in detail with reference to the drawings. In the drawings, the relative size of each element is exaggerated for clarity.
1A and 1B are diagrams showing an intermittent water refill according to the present invention, wherein FIG. 1A is a front view and FIG. 1B is a plan view.

図1(a)に示す間歇型補水器50は、樹脂製の気密ケース60と、気密ケース60の外部に設けられ気密ケース60の通気孔66を開閉する樹脂製の第1浮き部70と、気密ケース60の内部に設けられ給水口62aを開閉する樹脂製の第2浮き部80とから構成されている。   The intermittent water refill 50 shown in FIG. 1A includes a resin-made airtight case 60, a resin-made first floating portion 70 provided outside the airtight case 60, and opening and closing a ventilation hole 66 of the airtight case 60. A second floating portion 80 made of resin is provided inside the airtight case 60 and opens and closes the water supply port 62a.

気密ケース60は、直方体の下面が開口し、上面及び側面が気密的に閉じ、内部が大容積の浮き室60aと、小容積の気室60bの2室に隔壁64で区画されている。   The airtight case 60 is open at the lower surface of the rectangular parallelepiped, airtightly closed at the upper surface and side surfaces, and is internally partitioned by a partition 64 into two large-volume floating chambers 60a and small-volume air chambers 60b.

また、その気密ケース60の浮き室60aの一側の外側面壁63が、下面から所定寸法短く下面に第1通気溝60cが形成され、気室60bの一側の外側面壁65が区画隔壁64より短く下面に第2通気溝60dが形成されている。   Further, the outer surface wall 63 on one side of the floating chamber 60a of the airtight case 60 is shorter than the lower surface by a predetermined length, the first ventilation groove 60c is formed on the lower surface, and the outer surface wall 65 on one side of the air chamber 60b is separated from the partition wall 64. A short second ventilation groove 60d is formed on the lower surface.

この実施の形態において、第1通気溝60cの上面は、第2通気溝60dの下面より低くなるように形成され、第1通気溝60cの開口面積は、第2通気溝60dの開口面積より広く形成される。このことにより、気密ケース60内の空気の出し入れがスムーズになる。   In this embodiment, the upper surface of the first ventilation groove 60c is formed to be lower than the lower surface of the second ventilation groove 60d, and the opening area of the first ventilation groove 60c is wider than the opening area of the second ventilation groove 60d. It is formed. Thus, the air in and out of the airtight case 60 can be smoothly taken in and out.

また、浮き室60aの外側面壁63の下端には、外部に延びた水平板61が設けられ、水平板61には下向きに設けた給水パイプ接続部62が設けられている。   At the lower end of the outer side wall 63 of the floating chamber 60a, a horizontal plate 61 extending to the outside is provided, and the horizontal plate 61 is provided with a water supply pipe connecting portion 62 provided downward.

給水パイプ接続部62は、潅水用のタンク(図示省略)から落差などによる一定の水圧で供給される潅水を、給水パイプを接続して受ける部材で、パイプ受口を有し、逆L字形に曲げられて、水平板61から立ち上がる形に形成されている。給水パイプ接続部の下端は、水平板61の底部に開口した給水口62aとなっている。   The water supply pipe connection part 62 is a member that receives water supplied from a watering tank (not shown) at a constant water pressure due to a head drop by connecting a water supply pipe, has a pipe receiving port, and has an inverted L-shape. It is formed so as to be bent and rise from the horizontal plate 61. The lower end of the water supply pipe connection portion is a water supply port 62 a opened at the bottom of the horizontal plate 61.

さらに、水平板61の先端部には、第2浮き部80を回動自在に保持する嵌合軸67が設けられている。嵌合軸67には、第2浮き部80の第2連結部81の第2連結孔81aが嵌められ、第2浮き部80が水位の上下により嵌合軸67を軸として上下に回動する。   Further, a fitting shaft 67 that rotatably holds the second floating portion 80 is provided at a distal end portion of the horizontal plate 61. The second connecting hole 81a of the second connecting portion 81 of the second floating portion 80 is fitted to the fitting shaft 67, and the second floating portion 80 turns up and down around the fitting shaft 67 as the water level rises and falls. .

一方、気密ケース60の反対側の気室60b上面に第1浮き部70を回動自在に保持する左右の嵌合軸68が左右に設けられている。嵌合軸68には、第1浮き部70の第1連結部71の第1連結孔71aが嵌められ、第1浮き部70が水位の上下により嵌合軸68を軸として上下に回動する。   On the other hand, on the upper surface of the air chamber 60b opposite to the airtight case 60, left and right fitting shafts 68 that rotatably hold the first floating portion 70 are provided on the left and right. The first connecting hole 71a of the first connecting portion 71 of the first floating portion 70 is fitted to the fitting shaft 68, and the first floating portion 70 rotates up and down around the fitting shaft 68 as the water level rises and falls. .

気密ケース60の上面(天井部分)には、区画隔壁64の上面に当たる位置に、浮き室60aと気室60bの2室に跨るように開口した通気孔66が設けられている。すなわち、通気孔66の中心は、区画隔壁64の中心線上とされ、孔の直径は、区画隔壁64の幅より大きく形成され、浮き室60aと気室60bの両方の室に連通する構造とされている。   On the upper surface (ceiling portion) of the airtight case 60, a vent hole 66 is provided at a position corresponding to the upper surface of the partition wall 64 so as to extend over the floating chamber 60 a and the air chamber 60 b. In other words, the center of the ventilation hole 66 is set on the center line of the partition wall 64, the diameter of the hole is formed to be larger than the width of the partition wall 64, and the structure communicates with both the floating chamber 60a and the air chamber 60b. ing.

次に、第1浮き部70について説明する。   Next, the first floating portion 70 will be described.

第1浮き部70は、前記気室上面から延長した箇所に設けられた嵌合軸68に回動自在に支持される左右の第1連結部71と、左右の第1連結部71をつなぐ架橋部72と、から構成される。   The first floating portion 70 is a bridge connecting the left and right first connection portions 71 rotatably supported by a fitting shaft 68 provided at a location extending from the upper surface of the air chamber, and the left and right first connection portions 71. And a unit 72.

架橋部72には、通気孔66に対向する位置に通気塞ぎ栓73が設けられ、さらに第1連結部71の先端部の左右には、下向きに二つの第1箱部74が設けられ、第1箱部74には第1蓋74’が固定されて浮力体75となる。通気塞ぎ栓73は、耐候性を有する弾性部材からなる円柱形の栓を外竿部72に設けた取付け孔に嵌合している。   The bridge portion 72 is provided with a ventilation plug 73 at a position facing the ventilation hole 66, and further, two left and right first box portions 74 are provided on the left and right of the distal end portion of the first connection portion 71. The first lid 74 ′ is fixed to the one box part 74 to form a buoyant body 75. The ventilation plug 73 is formed by fitting a cylindrical plug made of a weather-resistant elastic member into a mounting hole provided in the outer rod portion 72.

第1箱部74と、第1蓋74’は、接着、溶着、耐水性の両面テープのいずれかにより固定され、中の密閉を保つ。   The first box portion 74 and the first lid 74 'are fixed by any one of adhesive, welding, and water-resistant double-sided tape to keep the inside tight.

第1浮き部70は、潅水が開始されて、間歇型補水器50が設置されている植栽容器の底部水位が上昇したとき、水中に浮かんだ浮力体75の浮力により第1連結部71が持ち上げられ、嵌合軸68を軸として上方に回動し、通気孔66に対向する位置に設けられ、通気孔66を塞いでいた通気塞ぎ栓73が上に移動し、通気孔66を開き、気密ケース60の浮き室60aと気室60b内の空気を上部(外部)に排出可能とする。   When the irrigation starts and the bottom water level of the planting vessel in which the intermittent rehydration device 50 is installed rises, the first floating portion 70 causes the first connecting portion 71 to float due to the buoyancy of the buoyant body 75 floating in the water. The vent plug 73 is lifted up, pivots upward about the fitting shaft 68, and is provided at a position facing the vent 66, and the vent plug 73 closing the vent 66 moves upward, opening the vent 66, The air in the floating chamber 60a and the air chamber 60b of the airtight case 60 can be discharged upward (outside).

この動きは、第1浮き部70の重量と、水中の浮力体75のバランスによるため、一定の水位となるまでは通気孔66を開かない。通気孔66が閉じられている間は、第2浮き部80は浮き室60a内の空気圧に妨げられて、浮力による上昇が規制される。   This movement depends on the balance between the weight of the first floating portion 70 and the buoyant body 75 in the water. While the ventilation hole 66 is closed, the second floating portion 80 is hindered by the air pressure in the floating chamber 60a, and the rise due to buoyancy is restricted.

次に、第2浮き部80について説明する。   Next, the second floating portion 80 will be described.

第2浮き部80は、気密ケース60の前方に延びた水平板61の先端部の嵌合軸67に回動自在に支持される第2連結部81と、気密ケース60の浮き室60a内に延びる内竿部82とからなり、内竿部82には水平板61の底面に設けられた給水口62aに対向する位置に給水塞ぎ栓83が設けられている。給水塞ぎ栓83は、耐候性を有する弾性部材からなる円柱形の栓を内竿部82設けた取付け孔に嵌合している。   The second floating portion 80 includes a second connecting portion 81 rotatably supported by a fitting shaft 67 at a distal end of a horizontal plate 61 extending forward of the airtight case 60, and a floating chamber 60 a of the airtight case 60. The inner rod portion 82 is provided with a water supply plug 83 at a position facing the water supply port 62 a provided on the bottom surface of the horizontal plate 61. The water supply plug 83 is formed by fitting a cylindrical plug made of an elastic member having weather resistance into a mounting hole provided in the inner rod portion 82.

浮き室60a内に延びる、内竿部82には第2箱部84と第2箱部84の第2蓋84’が設けられ、第2箱部84には第2蓋84’が固定されて、浮力体85を形成する。   The inner rod portion 82 extending into the floating chamber 60a is provided with a second box portion 84 and a second lid 84 'of the second box portion 84, and the second box portion 84 is fixed with a second lid 84'. , The buoyancy body 85 is formed.

第2箱部84と、第2蓋84’は、接着、溶着、耐水性の両面テープのいずれかにより固定され、中の密閉を保つ。   The second box portion 84 and the second lid 84 'are fixed by any one of adhesive, welding, and water-resistant double-sided tape to keep the inside tight.

なお、図1(a)に示すように、第2浮き部80の内竿部82は、浮力体85が底面についている際には、第2連結部81を軸として浮力体85が下向きとなる角度に形成されており、給水口62aに対向する位置の給水塞ぎ栓83が給水口62aから下方に離れ、給水口62aを開いた状態となるように形成されている。浮力体85の上面は、潅水水位が上昇したとき、浮き室60aの天井に到達するまで回動する。   As shown in FIG. 1A, when the buoyant body 85 is on the bottom surface, the buoyant body 85 of the inner rod portion 82 of the second floating portion 80 faces downward with the second connecting portion 81 as an axis. The water supply stopper plug 83 at a position facing the water supply port 62a is formed so as to be separated from the water supply port 62a downward, so that the water supply port 62a is opened. When the irrigation water level rises, the upper surface of the buoyant body 85 rotates until it reaches the ceiling of the floating chamber 60a.

図1(b)は、間歇型補水器50の平面図である。この図では、気密ケース60の上部に第1浮き部70が配設されている状態であり、気密ケース60は、前方に設けられた水平板61とそこから立ち上がる給水パイプ接続部62、水平板61の先端左右に設けられた嵌合軸67を示す。   FIG. 1B is a plan view of the intermittent rehydrator 50. In this figure, the first floating portion 70 is disposed above the airtight case 60, and the airtight case 60 is composed of a horizontal plate 61 provided at the front, a water supply pipe connecting portion 62 rising from the horizontal plate 61, and a horizontal plate. 6 shows a fitting shaft 67 provided on the left and right of the tip of 61.

第1浮き部70は、嵌合軸68に連結された第1連結部71と、第1連結部71の先端の左右に下向きに設けられた中空の二つの第1箱部74と、第1箱部74に固定された第1蓋74’からなる浮力体75を有する。   The first floating portion 70 includes a first connecting portion 71 connected to the fitting shaft 68, two hollow first box portions 74 provided downward on the left and right of the distal end of the first connecting portion 71, It has a buoyant body 75 composed of a first lid 74 ′ fixed to the box 74.

次に、図2を参照して気密ケース60についてさらに詳しく説明する。図2は気密ケース60の構造を示し、(a)は正面図、(b)は平面図である。   Next, the airtight case 60 will be described in more detail with reference to FIG. 2A and 2B show the structure of the airtight case 60, wherein FIG. 2A is a front view and FIG. 2B is a plan view.

図1の説明と同一の構造・機能については同符号を付して説明を省略する。   The same structures and functions as those described with reference to FIG.

図2(a)に示すように、水平板61は、気密ケース60の外側面壁63の下端、すなわち第1通気溝60cの上部から水平に延びるように設けられている。   As shown in FIG. 2A, the horizontal plate 61 is provided so as to extend horizontally from the lower end of the outer side wall 63 of the airtight case 60, that is, the upper part of the first ventilation groove 60c.

図2(a)に示すように、水平板61は、気密ケース60の外側面壁63の下端、すなわち第1通気溝60cの上部から水平に延びるように設けられている。   As shown in FIG. 2A, the horizontal plate 61 is provided so as to extend horizontally from the lower end of the outer side wall 63 of the airtight case 60, that is, the upper part of the first ventilation groove 60c.

水平板61の上面には、気密ケース60の外側面壁63と給水パイプ接続部62の間に延びる補強壁61bと、水平板61の両端に設けられた補強壁61aを備え、給水パイプの接続や、第2浮き部80の支持を確実に行えるよう補強されている。   The upper surface of the horizontal plate 61 is provided with a reinforcing wall 61b extending between the outer side wall 63 of the airtight case 60 and the water supply pipe connection portion 62, and reinforcing walls 61a provided at both ends of the horizontal plate 61, for connection of the water supply pipe. , So that the second floating portion 80 can be supported reliably.

気密ケース60の左右の側壁69は、底面まで延びているが、水平板61が延びる前部の外側面壁63は、短く形成され、底面との間に第1通気溝60cが開口した状態になっている。   The left and right side walls 69 of the airtight case 60 extend to the bottom surface, but the front outer side wall 63 from which the horizontal plate 61 extends is formed short, and the first ventilation groove 60c is opened between the left and right side walls 69 and the bottom surface. ing.

これに対し、気室60bの外側の外側面壁65は、わずかに短く、底面からの距離が第1通気溝60cより高く形成される。   On the other hand, the outer side wall 65 outside the air chamber 60b is slightly shorter, and is formed higher in distance from the bottom surface than the first ventilation groove 60c.

この実施の形態では、給水による潅水で上昇した水位が植物により消費され、水位が低下したとき、まず第2通気溝60dの開口から気室60b内に閉じ込められていた水が外部に排出され、外気と交換され、その後、第1通気溝60cの開口より水位が低下したとき、浮き室60a内に閉じ込められていた水が外部に排出され外気と交換され、浮き室60a内の水位が間歇型補水器の下に配置された水受け(図示せず)の水位と同じ位置まで下がる。   In this embodiment, when the water level raised by irrigation by water supply is consumed by the plants and the water level decreases, first the water trapped in the air chamber 60b is discharged from the opening of the second ventilation groove 60d to the outside, When the water level is lowered from the opening of the first ventilation groove 60c after being exchanged with the outside air, the water trapped in the floating chamber 60a is discharged to the outside and exchanged with the outside air, and the water level in the floating chamber 60a is intermittent. It descends to the same position as the water level of the water receiver (not shown) arranged under the water supplement.

また、気密ケース60の上面(天井部分)に開口した通気孔66は、中心が区画隔壁64の中心線上とされ、孔の直径は、区画隔壁64の幅より大きく形成され、浮き室60aと気室60bの両方の室に連通する構造とされているので、第2通気溝60dから気室60aに流入した外気は、通気孔66内の間隙を通過して浮き室60aにも流れ込むため、内部に閉じ込められた水がスムーズに排出されないために給水開始の動作(第2浮きの下降)が遅れる不具合を皆無にできる。   The ventilation hole 66 opened on the upper surface (the ceiling portion) of the airtight case 60 has the center on the center line of the partition wall 64, the diameter of the hole is larger than the width of the partition wall 64, and the air hole 66a Since the structure communicates with both of the chambers 60b, the outside air flowing into the air chamber 60a from the second ventilation groove 60d flows through the gap in the ventilation hole 66 into the floating chamber 60a. Since the trapped water is not discharged smoothly, the operation of starting the water supply (the lowering of the second float) is not delayed.

図2(b)は気密ケース60の平面図である。通気孔66が区画隔壁64の中心線上にあけられ、浮き室60aと気室60bの両方の室に連通する構造とされることを示す。   FIG. 2B is a plan view of the airtight case 60. This shows that the ventilation hole 66 is formed on the center line of the partition wall 64 and communicates with both the floating chamber 60a and the air chamber 60b.

図3は、第1浮き部70を示す図で、(a)は正面図、(b)は側面図である。   3A and 3B are views showing the first floating portion 70, wherein FIG. 3A is a front view and FIG. 3B is a side view.

図3(a)に示すように第1連結部71には、気密ケース60の嵌合軸68に回動自在にはめ込むための第1連結孔71aが形成されて、第1連結部71の先端部左右に形成された浮力体75が、水位の上昇で浮き上がることで、架橋部72にある通気塞ぎ栓73を上部に持ち上げて気密ケース60の通気孔66を開け、水位が一定以下の場合は通気孔66を塞いだ状態となる。   As shown in FIG. 3A, a first connection hole 71 a is formed in the first connection portion 71 so as to be rotatably fitted to the fitting shaft 68 of the airtight case 60. When the buoyancy body 75 formed on the left and right of the part rises due to the rise of the water level, the ventilation plug 73 in the bridging part 72 is lifted upward to open the ventilation hole 66 of the airtight case 60. The air hole 66 is closed.

この第1浮き部70は、気密ケース60の通気孔66の開閉により、気密ケース60内に設けられた第2浮き部80の動作を制御するもので、通気孔66が閉じられている間、気密ケース60の内部の空気により気密ケース60内の水位の上昇が抑制され、気密ケース60外部の水位が一定の水位に達し、通気孔66が開かれて内部の空気が排出されて気密ケース内の水位が上昇し第2浮き部80が浮き上がり、給水口62aが閉じられる。   The first floating portion 70 controls the operation of the second floating portion 80 provided in the airtight case 60 by opening and closing the air hole 66 of the airtight case 60, and while the air hole 66 is closed. The air inside the hermetic case 60 suppresses a rise in the water level inside the hermetic case 60, the water level outside the hermetic case 60 reaches a certain water level, the vent 66 is opened, and the air inside the hermetic case 60 is discharged, so that the air inside the hermetic case 60 is discharged. Rises, the second float 80 rises, and the water supply port 62a is closed.

図4は、第2浮き部80の平面図である。第2連結部81には、気密ケース60の嵌合軸67に回動自在に嵌めこむための第2連結孔81aが形成されて、浮力体85が、水位の上昇により浮き上がった際、内竿部82の基部に上向きに設けられた給水塞ぎ栓83を上に動かし、気密ケース60に設けられた給水口62aを塞ぎ、給水を停止させる。   FIG. 4 is a plan view of the second floating portion 80. The second connecting portion 81 is formed with a second connecting hole 81a for rotatably fitting the fitting shaft 67 of the airtight case 60. When the buoyant body 85 rises due to the rise of the water level, the inner rod is formed. The water supply plug 82 provided upward at the base of the part 82 is moved upward to close the water supply port 62a provided in the airtight case 60, and the water supply is stopped.

図5は、本発明の間歇型補水器50の動作状態を示す図で、(a)は給水開始状態の動作を示す断面図、(b)は給水停止状態の動作を示す断面図である。   5A and 5B are diagrams showing an operation state of the intermittent water replenisher 50 of the present invention, in which FIG. 5A is a cross-sectional view showing an operation in a water supply start state, and FIG. 5B is a cross-sectional view showing an operation in a water supply stop state.

図5(a)は、潅水された水位がW3の状態まで下がった場合を示す。すなわち、水位W3が第1通気溝60cと同じ高さとなった状態で、このとき、第2通気溝60dから気室60b内に閉じ込められていた水を排出し、外気が矢印Aのように流入し、通気孔66の間隙から浮き室60aにも流入し、浮き室60a内の閉じ込められた水をも第1通気溝60cから排出する。このため、浮き室内の水位がW3まで下がり、第2浮き部80が下がり、給水塞ぎ栓83が給水口62aから離れ、水圧がかかった給水が給水パイプ接続部62から流れ込む。   FIG. 5A shows a case where the level of the irrigated water has dropped to the state of W3. That is, in a state where the water level W3 is the same height as the first ventilation groove 60c, at this time, the water trapped in the air chamber 60b is discharged from the second ventilation groove 60d, and the outside air flows in as indicated by the arrow A. Then, the water flows into the floating chamber 60a from the gap of the ventilation hole 66, and the water trapped in the floating chamber 60a is also discharged from the first ventilation groove 60c. For this reason, the water level in the floating chamber drops to W3, the second floating portion 80 drops, the water supply plug 83 separates from the water supply port 62a, and the water supply with water pressure flows from the water supply pipe connection part 62.

図5(b)は、潅水された水位がW2の状態まで上がった場合を示す。このとき、第1浮き部70の浮力体75が浮き上がり通気塞ぎ栓73を通気孔66から離して、浮き室60a、空気室60b内の空気を矢印Bのように通気孔66から外部に流出させ、空気で遮られていた水が浮き室60a、空気室60bに流入して外部の水位W2と同じ高さまで満たす。このため、第2浮き部80の浮力体85が浮き上がり、内竿部82の先端に設けられた給水塞ぎ栓83が給水口62aを塞ぎ、給水を停止させる調節装置の構造を示す断面図である。   FIG. 5B shows a case where the level of the irrigated water has risen to the state of W2. At this time, the buoyant body 75 of the first floating portion 70 rises to separate the ventilation plug 73 from the ventilation hole 66, and the air in the floating chamber 60a and the air chamber 60b flows out from the ventilation hole 66 to the outside as shown by the arrow B. The water blocked by the air flows into the floating chamber 60a and the air chamber 60b and fills up to the same level as the external water level W2. Therefore, the buoyant body 85 of the second floating portion 80 is lifted up, and a water supply plug 83 provided at the tip of the inner rod portion 82 closes the water supply port 62a, and is a cross-sectional view showing the structure of the adjusting device for stopping water supply. .

図6は、防塵ケースに収納した本発明の間歇型補水器で、(a)は正面図、(b)は平面図である。ただし、防塵ケースについては断面を示す。   FIGS. 6A and 6B show an intermittent water refill according to the present invention housed in a dustproof case, wherein FIG. 6A is a front view and FIG. However, the cross section of the dustproof case is shown.

図6において、防塵ケース51は、給水パイプ52を通すパイプ孔51aを有する。間歇型補水器50は、プランターやパレット、鉢底などに装着されるが、栽培中は、殆ど動かしたり、清掃したりしないこととなる。このため、外部からの汚れの進入を防止するための防塵ケース51を被せることが望ましい。   6, the dustproof case 51 has a pipe hole 51a through which a water supply pipe 52 passes. The intermittent water replenisher 50 is mounted on a planter, a pallet, a pot bottom, or the like, but is hardly moved or cleaned during cultivation. For this reason, it is desirable to cover the dust-proof case 51 for preventing invasion of dirt from the outside.

本発明の間歇型補水器を用いることによれば、植物の種類、大きさ、気象条件の変化に応じた水と空気を交互に供給し、一滴の水も外には出すことなく、無動力で潅水し24時間的確に作動させることができるため、植物がストレスなく成長する。ストレスがない植物は、驚異的な成長を遂げる。   According to the use of the intermittent rehydration device of the present invention, the type and size of the plant, water and air are alternately supplied in accordance with changes in weather conditions, and a single drop of water does not go outside. And the plant can be operated accurately for 24 hours, so that the plant grows without stress. Stress-free plants grow tremendously.

ベランダなどの雨水が当たらない場所にあっては、植物栽培用給水台の上にあらゆる既存の鉢を置くだけで、底穴から水が供給され、容易に底面給水鉢とさせることができる。叉、植え込みの下に設置すれば、乾燥による枯死の防止が図られる。   In a place where rainwater does not hit, such as a veranda, water can be supplied from the bottom hole simply by placing all existing pots on the water supply stand for plant cultivation, and the bottom can be easily made into a water supply bowl. Moreover, if it is installed under the planting, it is possible to prevent death due to drying.

また、空間を利用したハンギングコンテナに取り付けることによれば、潅水の手間を省き、植物の水ストレスをなくせるため、植え替え無しで成長をさせることができる。   In addition, by attaching to a hanging container using a space, labor for watering can be saved and water stress of the plant can be eliminated, so that the plant can be grown without replanting.

また、屋上緑化のコンテナに用いれば、あらゆる植物の発芽、成長、繁茂を繰り返す植物栽培台とすることができる。土を使用せず軽量で、植物の葉と栽培台から大量の蒸発散を行わせることができる。   Moreover, if it is used for a container for rooftop greening, it can be used as a plant cultivation table that repeats germination, growth and prosperity of all plants. It is lightweight without using soil, and can make a large amount of evapotranspiration from plant leaves and cultivation table.

さらに、間歇型補水器の小型化により、傾斜屋根の角度に応じた可変式植物栽培鉢を実現できる。これによればあらゆる植物の葉を通し、大量の水を蒸散させることができる、しかも無駄な水の排出は一切ない花だらけの屋根面を実現できる。   In addition, a variable plant cultivation pot according to the angle of the sloping roof can be realized by downsizing the intermittent rehydrator. According to this, a large amount of water can be evaporated through the leaves of all the plants, and a roof surface full of flowers can be realized without any wasteful discharge of water.

また、間歇型補水器の小型化により、幅が薄く、壁面に取り付け可能な植栽ケースが可能となり、蒸散量の多い植物であっても壁面緑化が可能となる。   In addition, the downsizing of the intermittent rehydrator makes it possible to provide a planting case that is thin and can be mounted on a wall surface, and enables greening of the wall surface even for a plant with a large amount of transpiration.

人口地盤状に自然生態系を再現するビオトープを実現する際に、本発明の間歇型補水器を利用すれば、容易に実現が可能である。   When realizing a biotope that reproduces a natural ecosystem in the form of artificial ground, the intermittent rehydrator of the present invention can be easily realized.

本発明の間歇型補水器を用いることにより、時々刻々に変化する気象に対応できる植物本来の潅水が可能となり、屋上、傾斜屋根、壁面、歩道橋、街路灯、舗装面、中央分離帯等の環境条件の厳しい場所にあっても、あらゆる植物の選択ができるようになる。   By using the intermittent rehydration device of the present invention, it is possible to irrigation the original plant that can respond to the weather that changes every moment, and to improve the environment such as rooftops, sloped roofs, wall surfaces, pedestrian bridges, street lights, pavement surfaces, and median strips. You will be able to select any plant, even in harsh conditions.
