【発明の詳細な説明】 産業上の利用分野 本発明は、洋上石油備蓄タンク又はタンク船用等の浮防
油堤の連結装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floating oil barrier connecting device for offshore oil storage tanks or tank ships.
従来の技術 第１図は、一般的な洋上石油備蓄タンクとその浮防油堤

号Ｅ部で示すように連結されている。In FIG. 1, a plurality of offshore oil storage tanks A are provided side by side. In the unlikely event that one or more of these tanks A is broken and oil flows to the sea, oil is prevented from leaking to the open sea side and downward in FIG. Primary and secondary floating levee walls are provided as levees, and each floating levee is composed of a large number of steel floating levee main bodies 1, and adjacent main bodies 1 are designated by symbol E. Are linked together.

ことは洋上石油備蓄タンク船のまわりに設けられる浮防
油堤等にも同様に要求される。Problems to be Solved by the Invention As described above, in the offshore oil storage tank, in the event that the tank breaks and the oil flows to the sea, the floating dike must prevent the oil from flowing to the open sea. . And in such a case, each floating levee is pushed by the oil that has flowed over the sea, so that the connecting portion between them is extended, so that the entire floating levee is curved in an arc shape. It is required to maintain strength and ensure that oil is dammed. In addition, such a thing is similarly required for floating oil dams and the like provided around the offshore oil storage tanker.
しかし、このような要求を十分に満足して高い信頼性を
有する浮防油堤の連結装置は従来存在していない。However, there has not been a conventional connecting device for a floating oil levee that sufficiently satisfies such requirements and has high reliability.
本発明は、このような従来技術の課題を解決するために

れたオイルフェンスとを備えたものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a device for connecting a plurality of floating levees, which are separated from the rolling center between the upper part and the lower part of adjacent floating levees. And a spacer attached to one of the floating oil dams between the floating oil dams and an oil fence installed between the floating oil dams.

堤間の連結部は確実に伸びる。Operation According to the above means, when oil flows out from the offshore oil storage tanks or tank ships to the sea, each floating levee is pushed by the oil flowing to the sea and spreads between them. Since the upper and lower telescopic connecting members extend, the connecting portion between the floating oil dams surely extends.

止する。And, in addition to increasing the tension of these telescopic connecting members as they become longer, since they are mounted away from the center of rolling, they limit the rolling and sliding movement of the floating levee to prevent oil movement. The force applied to the fence can be reduced, and the safety of the oil fence can be improved. In addition, the spacers prevent collision between the floating oil dams.
実施例 以下、第２図、第３図を参照して本発明の一実施例につ

結されている。In these drawings, a floater 2 is attached to each of both side ends of a large number of steel floating levee main bodies 1 which constitute the floating levee for an offshore oil storage tank. The upper ends and the lower ends of the two adjacent floaters 2 are connected to each other by a connecting chain 3 as a telescopic connecting member.

Is installed. Furthermore, elastic oil fence 7
However, avoiding the mounting position of this spacer 5, the floater 2

る。Next, the operation will be described. Assuming that one or more of the offshore oil storage tanks A shown in FIG. 1 are broken, each floating levee body 1 is pushed by the oil flowing from the tank A to the sea, and the space between them is Although it expands, the upper and lower telescopic connecting chains 3 and the elastic oil fence 7 also expand accordingly, so that the connecting portion between the floating levee body main bodies surely expands, thereby making the entire floating levee arcuate. It has a curved shape and maintains strength, and oil can be reliably dammed by the floating levee body 1 and the oil fence 7.
そして、これら伸縮式連結チェーン３は、長さが長くな

ることができる。And, since these telescopic connecting chains 3 increase in tension as the length becomes longer and are mounted away from the center of rolling, they limit rolling and sliding movements between the floating oil dam main bodies, Thereby, the force applied to the oil fence 7 can be reduced, and the safety thereof can be improved.
また、浮防油堤本体１のフローター２間の距離が小さく
なっても、一方のフローター２に取付けたスペーサ５の
先端部のゴム６が他方のフローター２に当接するので、
フローター２同志の衝突を防止することができる。Even if the distance between the floaters 2 of the floating levee body 1 becomes small, the rubber 6 at the tip of the spacer 5 attached to one floater 2 contacts the other floater 2,
It is possible to prevent a collision between the floaters 2.
更に、このスペーサ５の取付位置をかわしてオイルフェ

結チェーン３などの取付けも簡単に行うことができる。Further, as a result of attaching the oil fence 7 to the end of the floater 2 by avoiding the attachment position of the spacer 5, the unbalance of the center of gravity and the buoyancy adjustment occurring in the floating levee body 1 are
This can be easily performed by using a ballast put in the bottom portion of the floater 2, and thus the oil fence 7, the connecting chain 3, etc. can be easily attached.
なお、本発明は、以上述べた洋上石油備蓄タンク用浮防
油堤のみならず、洋上石油備蓄タンク船用等の浮防油堤
の連結にも同様に適用できるものである。The present invention can be applied not only to the above-mentioned floating oil levee for offshore oil storage tanks, but also to the connection of floating oil levee for offshore oil storage tank vessels.
