Abstract

Ved ifølge frembringelsen at opbygge en flydespærre (1O) ved hjælp af ensartede flydelegemer (1), ophængt på en wire (9), vil der kunne dannes en effektiv flydespærre, idet denne - i afhængighed af antallet af flydelegemer - vil kunne have enhver ønsket længde, som kan tildannes på stedet. Flydespærren vil være let at fremføre gennem vandet, da de enkelte flydelegemer er lettere end vand og derfor kun er delvist nedsænkede. Hertil kommer, at flydespærren let kan trækkes hen over forhindringer, da de enkelte flydelegemer kan "rulle" ligesom de kan dreje sig og bøje sig i forhold til hinanden på wiren.By constructing a float block (10) by means of uniform float bodies (1), suspended on a wire (9), an efficient float block can be formed, which - depending on the number of float bodies - can have any desired length that can be formed at the site. The float barrier will be easy to move through the water as the individual float bodies are lighter than water and therefore only partially submerged. In addition, the floating block can easily be pulled over obstacles, as the individual floating bodies can "roll" just as they can rotate and bend relative to each other on the wire.

Description

FLYDESPÆRRE F.EKS. TIL BRUG VED INDDÆMNING AF OLIEUDSLIP Den kendte teknikFLOAT BLOCK eg. FOR USE BY RECOVERING OIL EMISSIONS The prior art

Frembringelsen angår en flydespærre f.eks. til brug ved inddæmning af olieudslip og andet flydende på vandoverflader, hvilken flydespærre består af flydelegemer, som er forbundet ved hjælp af en gennemgående snor eller wire.The production relates to a flow barrier, e.g. for use in the containment of oil spills and other liquid on water surfaces, which float block consists of floating bodies connected by a continuous string or wire.

Flydespærrer af denne art kendes i mange forskellige udførelsesformer. Det eneste krav der bliver stillet til en flydespærre er, at den består af en langsgående mere eller mindre fleksibel spærre, som kan flyde på vandoverfladen og som kan fremføres og derved omkranse eventuelt olieudslip således, at oliemkan pumpes op.Float barriers of this kind are known in many different embodiments. The only requirement placed on a float barrier is that it consists of a longitudinal more or less flexible barrier which can float on the water surface and which can be fed, thereby encircling any oil spill so that the oil can be pumped up.

Fra US 3,651,647 A1 kendes et eksempel på en flydespærre omfattende et antal hule vandtætte beholdere, som er indbyrdes forbundne ved hjælp af en wire. Denne flydespærre er både pladskrævende og besværlig i brug, hvilket gør den upraktisk at transportere og udlægge.From US 3,651,647 A1 there is known an example of a flow barrier comprising a number of hollow waterproof containers which are interconnected by means of a wire. This float barrier is both space consuming and cumbersome to use, making it impractical to transport and lay.

For at forenkle dette kendes en spærre som består af mindre enheder fremstillet af f.eks. opskummet kunststof, kork og lignende, som holdes sammen af en gennemgående snor eller wire.In order to simplify this, a barrier consisting of smaller units made of e.g. foamed plastic, cork and the like, held together by a continuous string or wire.

Eller spærren kan bestå af en langsgående lufttæt luftpude, som kan oppumpes og dermed flyde på vandoverfladen.Or the barrier may consist of a longitudinal airtight air cushion which can be inflated and thus float on the water surface.

Alle disse kendte spærrer er imidlertid besværlige at håndtere, da de enten kræver meget plads eller meget forarbejde før de kan tages i brug.However, all of these known barriers are difficult to handle as they either require a lot of space or a lot of preprocessing before they can be put into use.

Formålet med frembringelsenPurpose of production

Formålet med frembringelsen er at forbedre flydespærren, det vil sige øge dens evne til at inddæmme olie og andet flydende, lette dens fremføring gennem vandet og samtidig gøre det så lidt pladskrævende som muligt og uden forudgående arbejde med dannelse af spærren.The purpose of the invention is to improve the flow barrier, that is, increase its ability to contain oil and other liquid, facilitate its passage through the water and at the same time make it as little space-consuming as possible and without prior work on forming the barrier.

Dette opnås ifølge frembringelsen hvis flydespærrens enkelte flydelegemer består af et sekskantet legeme omfattende en sekskantet midterskive, som på begge sider er forsynet med tværgående ribber og med en midt på skiven opretstående bøsning, som er forsynet med en gennemgående boring.This is achieved according to the invention if the single floating body of the float consists of a hexagonal body comprising a hexagonal center disc, which is provided on both sides with transverse ribs and with a centered upright bushing provided with a through bore.

På denne måde vil flydelegemerne trukket på wiren blive fastholdt med ribbernes højde som afstand til hosliggende legemer, hvilket dels gør spærren let at trække gennem vandet, med ringe vandmodstand og ribberne og skiverne vil udgøre en effektiv spærre for det på overfladen flydende udslip.In this way, the floating bodies drawn on the wire will be retained with the height of the ribs as a distance to adjacent bodies, which in part makes the barrier easy to pull through the water, with low water resistance and the ribs and discs will constitute an effective barrier for the surface liquid discharge.

Flydespærren kan yderligere anvendes som bølgedæmper, idet den kan udlægges i f.eks. en rundkreds omkring et arbejdsområde på havet og dermed dæmpe bølgerne indenfor spærren. Dette vil have stor praktisk betydning ved arbejde på havet.The float barrier can further be used as a shock absorber as it can be laid out in e.g. a circle around a work area at sea, thus damping the waves within the barrier. This will have great practical significance when working at sea.

Ved, som omhandlet i krav 2, at give bøsningerne på hver side af flydelegemet en højde som mindst svarer til ribbernes højde, vil hosliggende bøsninger udgøre et afstandsstykke, som samtidig tillader de enkelte legemer at dreje og bøje omkring denne anlægsflade.By providing, as claimed in claim 2, the bushings on each side of the buoyant body at least equal to the height of the ribs, adjacent bushings will constitute a spacer which at the same time allows the individual bodies to rotate and bend around this abutment surface.

Ved, som omhandlet i krav 3, at fremstille flydelegemerne i kunststof med en massefylde som er mindre end en, vil legemerne i deres vertikale position, flyde med omkring halvdelen af midterskiven nedsænket i vandet. Dette medvirker dels til at flydelegemet er relativt let at trække gennem vandet og dermed at fremføre under inddæmningsarbejdet.By making, as claimed in claim 3, the plastic floating bodies having a density less than one, the bodies in their vertical position will flow with about half of the center disc immersed in the water. This partly contributes to the floating body being relatively easy to pull through the water and thus conveying during the containment work.

Ved, som omhandlet i krav 4, at udforme endefladen på bøsningen plan og parallel med midterskiven, vil de enkelte flydelegemer blive fastholdt i samme position på wiren til sikring afen ubrudt spærreevne.As defined in claim 4, to design the end face of the sleeve plane and parallel to the center disc, the individual floating members will be held in the same position on the wire to ensure uninterrupted blocking performance.

Ved, som omhandlet i krav 5, at trække et antal legemer på en wire gennem boringerne, kan der dannes en aflang fleksibel flydespærre med enhver ønsket længde.By drawing a plurality of bodies on a wire through the bores, as claimed in claim 5, an elongated flexible flow barrier can be formed of any desired length.

Ved, som omhandlet i krav 6, at lade ribberne og midterskiven med deres relative store overflade flyde i vandoverfladen, vil der dannes en relativ stor adhæsionsoverflade, som effektivt vil holde olien samlet.By, as defined in claim 6, allowing the ribs and center disc with their relatively large surface to flow into the water surface, a relatively large adhesion surface will be formed which will effectively keep the oil together.

Ved, som omhandlet i krav 7, at de enkelte flydelegemer kan dreje individuelt på wiren, hvorved flydespærren kan ’’rulle” hen over eventuelle opadragende genstande i vandet.Know as defined in claim 7, that the individual floating bodies can rotate individually on the wire, whereby the float block can '' roll 'over any upward objects in the water.

Endelig er det hensigtsmæssigt, som omhandlet i krav 8, at trække en strømpe af f.eks. vævet stof over flydelegemerne, idet det derved vil øge spærrens evne til at absorbere olie og andet flydende.Finally, as claimed in claim 8, it is appropriate to pull a stocking of e.g. woven fabric over the floating bodies, thereby increasing the barrier's ability to absorb oil and other liquid.

TegningenThe drawing

Et eksempel på en foretrukken udførelsesform for frembringelsen vil i det følgende blive nærmere beskrevet under henvisning til tegningen, hvor fig. 1 viser et enkelt flydelegeme set i perspektiv, fig. 2 viser to flydelegemer trukket på en wire og fig. 3 viser en af flydelegemer dannet flydespærre udlagt på vandet.An example of a preferred embodiment of the invention will be described in more detail below with reference to the drawing, in which: FIG. 1 is a perspective view of a single floating body; FIG. 2 shows two floating bodies drawn on a wire and FIG. 3 shows a float block formed on the water.

Beskrivelse af et udførelseseksempel På fig. 1 og 2 er vist et foretrukket eksempel på et flydelegeme 1.Description of an embodiment In FIG. 1 and 2 are shown a preferred example of a floating body 1.

Dette flydelegeme er formet som et sekskantet legeme med en midterdel dannet af seks trekantede pladedele 3a-3f, som ved pladedelenes centrum har en på begge sider vinkelret udragende bøsning 6, med en gennemgående boring 5.This floating body is shaped like a hexagonal body with a central part formed by six triangular plate parts 3a-3f, which at the center of the plate parts has a sleeve 6 perpendicular to both sides, with a through bore 5.

Pladedelene er på begge sider samlet med vinkelrette herpå udragende ribber 2a-2f, som fra bøsningen 6 buer nedefter mod enden af pladekanterne.The plate parts are assembled on both sides with perpendicular ribs 2a-2f perpendicular thereto, which from the bushing 6 arc downwards towards the end of the plate edges.

Flydelegemet er fortrinsvis fremstillet ved støbning i kunststof med en massefylde som er mindre end en.The floating body is preferably made by molding in plastic with a density less than one.

Disse flydelegemer 1 kan trækkes på en wire 9, som vist på fig. 2, og vil dermed udgøre en flydespærre 10, der som eksempel er vist på fig. 3.These floating bodies 1 can be drawn on a wire 9, as shown in FIG. 2, and will thus constitute a flow barrier 10, which is shown by way of example in FIG. Third

På grund af flydelegemernes 1 udformning og dimensionering vil den af disse legemer dannede flydespærre besidde store fordele. Først og fremmest vil den være let at fremføre gennem vandet 7 på grund af den ringe vandmodstand, som alene består i fremføring af et halvt flydelegeme i dennes vertikale position, som antydet på fig. 3.Due to the design and dimensioning of the floating bodies 1, the floating barrier formed by these bodies will have great advantages. First of all, it will be easy to pass through the water 7 due to the low water resistance, which consists solely of feeding half a floating body in its vertical position, as indicated in FIG. Third

Ribberne og flydelegemets nedsænkede pladehalvdel vil udgøre en effektiv adhæsion på olie og andet klæbende udslip, ligesom legemet vil rulle let gennem vandet, idet de individuelle legemer kan dreje sig frit på wiren 9.The ribs and the submerged plate half of the float will provide an effective adhesion to oil and other adhesive spills, and the body will roll easily through the water, allowing individual bodies to rotate freely on the wire 9.

Hvis flydespærren møder en forhindring, som rager op over vandoverfladen, vil flydespærren kunne ’’rulle” hen over forhindringen uden at tage skade.If the floating barrier encounters an obstacle that protrudes above the water surface, the floating barrier will be able to '' roll 'across the obstacle without damaging it.

For at øge evnen til at opsuge f.eks. olie, kan flydelegemerne på wiren overtrækkes med en ikke vist strømpe, som kan være af vævet kunststof og lignende. Herved øges adhæsionen og dermed evnen til at fastholde f.eks. olie i betydelig grad.To increase the ability to absorb e.g. oil, the float bodies on the wire can be coated with a stocking not shown, which may be of woven plastic and the like. This increases the adhesion and thus the ability to retain e.g. oil to a considerable extent.

Flydespærren vil kunne dannes i enhver længde blot ved at øge eller mindske antallet af flydelegemer. Dette sammen med den ubrudte spærreevne, som de hosliggende legemer vil udgøre, gør at den er let at tilpasse efter det aktuelle behov, ligesom der ikke vil være risiko for manglende brugsegenskaber. Hertil kommer at den vil være let at fremføre gennem vandet.The float barrier can be formed at any length simply by increasing or decreasing the number of float bodies. This, together with the uninterrupted blocking ability of the adjacent bodies, makes it easy to adapt to the current needs, and there is no risk of missing use properties. In addition, it will be easy to convey through the water.

Hvis der opstår forhindringer vil flydespærren være mindre udsat for beskadigelse, da den kan afbøje, eventuelt ’’rulle” hen overforhindringen.If obstacles occur, the float will be less prone to damage as it can deflect, possibly 'roll' over the obstruction.

Materialet, som 'elementerne er fremstillet af, er som nævnt lettere end vand og da kunststoffet er modstandsdygtigt overfor kemikalier og UV lys, vil den kunne holde i lang tid uden at dens egenskaber som flydespærre forringes.As mentioned, the material from which the elements are made is lighter than water and since the plastic is resistant to chemicals and UV light, it will be able to last for a long time without deteriorating its properties as a liquid barrier.
