Description

Detailed Description of the Invention

本発明は、水位の変化により上下に可動可能な水中膜の係留装置に関する。The present invention relates to an underwater membrane mooring device that can be moved up and down by a change in water level.

従来、ポンプ所・取水口・沈砂池等に展張されている水位の変化により上下に可動するオイルフェンス１等は、オイルフェンスの上部近傍にリング２を設け、このリングを護岸等に設けられたガイドポール３に挿通して設置されていた（図１参照）。また他の方法として護岸等に設けられた中空管４を用い、該中空管に垂直にスリット状の切り欠き部５を設け、該中空管内を摺動可能なフロート状金具６をオイルフェンス１の両端部に設けた装置が知られている（図２参照）。
さらに、水中膜の上部近傍部の両端部に、水中膜に対してそれぞれ直角方向（二方向）にアームを設け、該アームに補助フロートを設け、かつ前記水中膜の上部近傍部の両端部にリングを設け、該リングを、ガイドポールに挿通し、該ガイドポールを護岸等に固定してなる装置が知られている。
しかしながら図１のような装置はリングの重みで長時間の間に水平位置が保たれずに垂れさがった状態になり、また水流により水中膜が傾斜することによってリングが斜めになることからガイドポールとの間に摩擦力が増大して結果的にリングがガイドポールに引っかかる状態となり、水位の変化によって水中膜が上下に可動することが不可能となる欠点があった。
また、図２のような装置はフロート状金具６の浮力を増す方法として、フロート状金具６を長くすることや径を大きくすることが上げられるが、フロート状金具６を長くすると金具の重量が大きくなり、その結果、浮力の増加が小さいことや、該中空管４内のフロート状金具６がつかえる状態となり、水位の変化によって水中膜が上下に可動することが不可能となる。フロート状金具６の径を大きくすると浮力は増加するが、該中空管４の径も大きくなり、高価格になる欠点があった。Conventionally, an oil fence 1 etc. that can move up and down due to changes in the water level that has been extended to pump stations, water intakes, sand basins, etc. has been provided with a ring 2 near the upper part of the oil fence, and this ring has been provided on a seawall etc. It was installed through the guide pole 3 (see FIG. 1). As another method, a hollow pipe 4 provided on a revetment or the like is used, a slit-like cutout portion 5 is provided perpendicularly to the hollow pipe, and a float-like metal fitting 6 slidable in the hollow pipe is provided as an oil fence. 1 is known (see FIG. 2).
Furthermore, an arm is provided at both ends of the vicinity of the upper portion of the underwater membrane in a direction perpendicular to the underwater membrane (two directions), an auxiliary float is provided on the arm, and both ends of the upper vicinity of the underwater membrane are provided. There is known an apparatus in which a ring is provided, the ring is inserted into a guide pole, and the guide pole is fixed to a seawall or the like.
However, the device as shown in FIG. 1 is in a state where the horizontal position is not maintained for a long time due to the weight of the ring, and the ring is inclined due to the inclination of the underwater film due to the water flow. As a result, the frictional force increases and as a result, the ring is caught on the guide pole, and the underwater film cannot be moved up and down due to the change in the water level.
Further, in the apparatus as shown in FIG. 2, as a method of increasing the buoyancy of the float fitting 6, it is possible to increase the length of the float fitting 6 or increase the diameter. However, if the float fitting 6 is lengthened, the weight of the fitting is increased. As a result, the increase in buoyancy is small, and the float-like metal fitting 6 in the hollow tube 4 can be used, and the underwater film cannot be moved up and down due to the change in the water level. When the diameter of the float metal fitting 6 is increased, the buoyancy is increased, but the diameter of the hollow tube 4 is also increased, resulting in a high price.

そこで本発明者は、急激な水位上昇によっても水中膜に設けられたリングがガイドポールに引っかからず、水中膜が上下にスムーズに可動する水中膜について種々研究を重ねた結果本発明を完成するに至った。 Therefore, the present inventor completed the present invention as a result of various researches on an underwater film in which the ring provided in the underwater film does not get caught by the guide pole even when the water level suddenly rises and the underwater film moves smoothly up and down. It came.

すなわち、本発明は、水中膜の上部近傍部の両端部に、水中膜に対してそれぞれ直角方向にアームを設け、該アームに補助フロートを設け、かつ前記水中膜の上部近傍部の両端部にリングを設け、該リングをガイドポールに挿通し、さらに該リングの下部に補助ブイをガイドポールに挿通して設け、前記ガイドポールを壁面等に固定してなる、水位の変化によって上下に可動可能な水中膜の係留装置である。That is, according to the present invention, arms are provided at both ends of the vicinity of the upper part of the underwater film, respectively, in the direction perpendicular to the underwater film, an auxiliary float is provided on the arm, and both ends of the vicinity of the upper part of the underwater film. A ring is provided, the ring is inserted through the guide pole, and an auxiliary buoy is inserted through the guide pole at the bottom of the ring. The guide pole is fixed to the wall surface, etc. This is an underwater membrane mooring device .

本発明方法によれば、水中膜は急激な水位上昇、また上下可動する場合にガイドポール３にリング１８が引っかかることもなく水位の変化に応じてスムーズに上下動を行うことができる。
また使用する補助ブイは、既設のガイドポール等を改良することなく設置が可能で、補助ブイも安価である。According to the method of the present invention, the underwater film can move up and down smoothly in response to a change in the water level without a ring 18 being caught by the guide pole 3 when the water level rapidly rises and moves up and down.
The auxiliary buoy to be used can be installed without improving the existing guide pole and the like, and the auxiliary buoy is also inexpensive.
