Description
【発明の詳細な説明】 産業上の利用分野 本発明は放水路に設けられる消泡装置に関する。[Detailed description of the invention] Industrial applications The present invention relates to a defoaming device installed in a waterway.
従来の技術 ゛
放水路から落差のある海に放水する箇所には、従来は堰
などが設けられており、その放水路に流された水は上記
層を越えて落差のある海に落下、流出させていた。Conventional technology ``Conventionally, a weir or the like is installed at the point where water is discharged from the spillway to the sea where there is a difference in head, and the water flowing into the spillway goes over the above layer and falls into the sea with a difference in head and flows out. I was letting it happen.
発明が解決しようとする課題
しかしながら、上記のように放水路に流した水を堰を越
えて落差のある海に流出させると、海への落下の際に空
気を混入して多量の泡が発生し、赤潮が発生することが
あった。Problems to be Solved by the Invention However, when the water that has been poured into the spillway is allowed to flow over a weir into the sea, as described above, air is mixed in when it falls into the sea, creating a large amount of foam. However, red tide sometimes occurred.
本発明は上記問題点を解決するもので、落差のある海へ
放水路からの水を流す際に、泡が発生しない消泡装置を
得ることを目的とするものである。The present invention solves the above-mentioned problems, and aims to provide a defoaming device that does not generate foam when water is discharged from a waterway into the sea with a head.
課題を解決するための手段
上記問題点を解決するため、本発明は、放水路上に整流
翼を設け、こ整流翼と上記放水路とにより形成される通
路の入口断面積より出口断面積の方が小さくなるように
上記整流翼を形成し、かつ上記整流翼の入口側端縁が上
流側水面に接するようにこの整流翼を移動可能としたも
のである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a straightening vane on the water discharge channel, and the outlet cross-sectional area of the passage formed by the straightening vane and the water discharge channel is larger than the inlet cross-sectional area. The baffle is formed such that the baffle is small, and the baffle is movable so that the edge on the inlet side of the baffle comes into contact with the water surface on the upstream side.
作用
上記構成により、整流翼の入口側端縁を上流側水面に接
する位置に整流翼を移動させて配置することにより上流
側からの放水流が整流翼と放水路との間に流入する際に
空気を巻き込むことはなくなり、また通路の入口断面積
より出口断面積を小さくしたので、通路内に安定した管
路流が形成される、これにより放水流の海への流入時に
おける空気の混入がなくなり泡の発生が防止される。Effect With the above configuration, by moving and arranging the baffle to a position where the inlet side edge of the baffle is in contact with the water surface on the upstream side, when the water discharge from the upstream side flows into between the baffle and the waterway. Air is no longer entrained, and since the outlet cross-sectional area is smaller than the inlet cross-sectional area of the passage, a stable pipe flow is formed within the passage, which prevents air from entering the water stream when it flows into the sea. This prevents the formation of bubbles.

口高さＹの方が小さくなるように構成されている。1 and 2 are a longitudinal sectional view and a front view of a defoaming device showing one embodiment of the present invention. In Figures 1 and 2, reference numeral 1 denotes a pair of gate structures installed on both sides of the outlet to the sea side of the spillway, and at the bottom of the outlet of the spillway, there is a weir 2 whose downstream side slopes downward. is formed, and steel rectifier blades 3 whose downstream side similarly slopes downward are disposed between the gate structures 1, facing the layer 2. A control 1ie4 installed on the gate structure 1 is disposed above the straightening blade 3, and on both sides between the control a4 and the Il flow blade 3 for moving the straightening blade 3. Hydraulic cylinder 5
are arranged in pairs in the front-rear direction when viewed from the front. The upper end of each hydraulic cylinder 5 is connected to an operation chamber 6 provided on both sides of the upper part of the control bridge 4, while the lower end is connected to a support base 7 fixed to the upper surface of both sides of the rectifying blade 3 via a shaft 8. It is hinged. Further, a roller 9 is provided to protrude laterally from the support base 7, and as shown in FIG. You will be guided to move up and down. and,
When the straightening blade 3 is moved so that its inlet side edge 3a is in contact with the upstream water surface, the outlet is lower than the entrance height X of the passage 11 formed by the straightening blade 3 and the upper surface of the weir 2 of the waterway. The height Y is configured to be smaller.
上流側より放水された流れは整流翼３と放水路の堰２上
面とにより形成された通路１０を通って海に排出される
が、この場合整流翼３の入口側端縁３ａは上流側水面に
接する位置にあるため、通路１０内に空気を混入するこ
となく、また、通路１０の入口高さＸより出口高さＹが
小さいので通路１０内に安定した管路流が形成される。The water discharged from the upstream side is discharged into the sea through the passage 10 formed by the straightening blade 3 and the upper surface of the weir 2 of the spillway, but in this case, the inlet side edge 3a of the straightening blade 3 is connected to the upstream water surface. Because it is in contact with the passageway 10, no air is mixed into the passageway 10, and since the outlet height Y is smaller than the entrance height X of the passageway 10, a stable pipe flow is formed within the passageway 10.
これにより放水流の海への流出時における泡の発生が防
止される。This prevents foam from forming when the water discharges into the sea.
なお、第４図に示すように、前後の油圧シリンダー５の

こともできる。In addition, as shown in FIG. 4, by changing the strokes of the front and rear hydraulic cylinders 5, the outlet side edge 3b of the straightening blade 3 is connected to the weir 2.
The water flow can also be dammed by making it come into contact with the slope.

果赤潮の発生を防止できる。Effects of the Invention As described above, according to the present invention, since the structure is such that the inlet side edge of the straightening blade can be placed at the upstream water surface position, air cannot be mixed into the passage between the straightening blade and the waterway. Since the cross-sectional area of the exit is smaller than the cross-sectional area of the entrance of the passage,
A stable conduit flow is created within the passage. This prevents the generation of bubbles when the discharged water flows into the sea, and as a result, the occurrence of red tide can be prevented.
