Description

Opfindelsen angår en flydespærring af den art, der omfatter et antal separate opdriftskamre, et skørt, en ballast og en luftforsyningsledning, hvor opdriftskamrene er placeret ved skørtets ene kant og ballasten 5 ved skørtets anden kant, der efter udlægning af flydespærringen ligger under den første kant, og hvor hvert opdriftskammer har sin egen forbindelse til luftforsyningsledningen. Opfindelsen angår også en fremgangsmåde ved anvendelse af en flydespærring af den nævnte art, 10 hvor luftforsyningsledningen er anbragt ved skørtets anden kant.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a float barrier of the type comprising a plurality of separate buoyancy chambers, a skirt, a ballast and an air supply line, the buoyancy chambers being located at one edge of the skirt and the ballast 5 at the other edge of the skirt, which, after laying the float barrier, is located below the first edge. , and where each buoyancy chamber has its own connection to the air supply line. The invention also relates to a method of using a float barrier of said kind, wherein the air supply line is arranged at the other edge of the skirt.

Der kendes flydespærringer af den nævnte art, hvor opdriftskamrene er udformede som lukkede kamre med en lufttilgang og eventuelt med en ventil for tømning 15 af opdriftskammeret for luft i forbindelse med bjærgning af flydespærringen. Ved udlægning af sådanne flydespærringer skal tilgangstrykket til luftforsyningsledningen, for at undgå sprængning af opdriftskamrene, holdes lavere end sprængtrykket for disse. Punkterer et 20 af opdriftskamrene, tømmes alle opdriftskamrene via den fælles luftforsyningsledning og flydespærringen synker.There are known flow barriers of the kind mentioned, in which the buoyancy chambers are designed as closed chambers with an air inlet and optionally with a valve for emptying the buoyancy chamber for air in connection with salvage of the float block. When laying such flow barriers, the supply pressure to the air supply line, in order to avoid bursting the buoyancy chambers, must be kept lower than the bursting pressure for these. If a 20 of the buoyancy chambers is punctured, all the buoyancy chambers will be emptied via the common air supply line and the flow barrier will sink.

Flydespærringen ifølge opfindelsen er ejendommelig ved, at der for hvert opdriftskammer er mindst én kanal, der forløber fra den indvendige side af op-25 driftskammeret til en udmunding, som er beliggende mellem opdriftskammeret og skørtets anden kant.The flow barrier according to the invention is characterized in that for each buoyancy chamber there is at least one channel extending from the inner side of the operating chamber to an outlet located between the buoyancy chamber and the other edge of the skirt.

Herved opnås, at overtrykket i opdriftskamrene begrænses, uden at det er nødvendigt at begrænse tilgangstrykket til luftforsyningsledningen, som derved 30 kan fremføre tilgangsluften under højere tryk og dermed opnås en større volumenstrøm i og/eller en mindre dimension af luftforsyningsledningen.Hereby, the overpressure in the buoyancy chambers is obtained without the need to limit the supply pressure to the air supply line, which can thereby supply the supply air under higher pressure and thus a larger volume flow in and / or a smaller dimension of the air supply line is obtained.

Den enkelte kanal har en udmunding, som i brugsstillingen er beliggende under opdriftskammeret. Ved 35 opblæsning af opdriftskammeret vil vandets niveau i kanalen falde ved stigende tryk i opdriftskammeret indtilEach channel has an outlet which is located in the position of use under the buoyancy chamber. Upon inflating the buoyancy chamber, the water level in the channel will decrease with increasing pressure in the buoyancy chamber until

DK 165012 BDK 165012 B

2 luften begynder at boble ud ved kanalens udmunding.2 the air begins to bubble out at the outlet of the duct.

Dette sker når trykket i opdriftskammeret har nået det tryk, der er i det omgivende vand ud for kanaludmundingen, således at trykket i opdriftskammeret er begrænset 5 til dette omgivende vandtryk.This occurs when the pressure in the buoyancy chamber has reached the pressure in the surrounding water off the channel outlet, so that the pressure in the buoyancy chamber is limited to this ambient water pressure.

En yderligere fordel ved flydespærringen ifølge opfindelsen er, at kanalerne kan benyttes til tømning af opdriftskamrene for luft i forbindelse med bjærgning af flydespærringen.A further advantage of the flow barrier according to the invention is that the ducts can be used for emptying the buoyancy chambers for air in connection with salvage of the flow barrier.

10 En foretrukket udførelsesform for opfindelsen er ejendommelig ved, at hvert opdriftskammers forbindelse til luftforsyningsledningen udmunder i en til kammeret hørende kanal. Herved opnås ved faldende tryk en afspærring af luftforsyningsledningsforbindelsen mellem 15 opdriftskamrene således, at punktering af et enkelt opdriftskammer ikke forårsager en tømning af alle opdriftskamrene. Ved faldende tryk i ét opdriftskammer vil det omgivende vand stige op i kanalen, og når vandet når luftforsyningsudmundingen, vil vandets tryk 20 forhindre yderligere tilstrømning af luft fra de øvrige opdriftskamre, som således vil kunne opretholde et tryk, der er i det omgivende vand ud for luftforsyningsudmundingen .A preferred embodiment of the invention is characterized in that the connection of each buoyancy chamber to the air supply line opens into a duct belonging to the chamber. Hereby, at decreasing pressure, a shut-off of the air supply line connection between the buoyancy chambers is achieved so that puncturing a single buoyancy chamber does not cause an emptying of all the buoyancy chambers. At decreasing pressure in one buoyancy chamber, the surrounding water will rise in the channel and as the water reaches the air supply outlet, the pressure of the water 20 will prevent further inflow of air from the other buoyancy chambers which will thus be able to maintain a pressure that is in the surrounding water out. for the air supply outlet.

En yderligere foretrukket udførelsesform ifølge 25 opfindelsen er ejendommelig ved, at luftforsyningsled-ningen er placeret ved skørtets anden kant, og at hvert opdriftskammers forbindelse til luftforsyningsledningen omfatter et grenrør. Herved opnås en særlig enkel produktions- og servicevenlig opbygning af luftforsynings-30 ledningens forbindelse til opdriftskammeret. Den færdige luftforsyningsledning med grenrør monteres her ved skørtets anden kant og grenrørene stikkes op i den tilhørende kanal, hvorved grenrørets udmunding danner luftforsyningsudmundingen til det til kanalen hørende 35 opdriftskammer.A further preferred embodiment of the invention is characterized in that the air supply line is located at the other edge of the skirt and that each buoyancy chamber connection to the air supply line comprises a manifold. This results in a particularly simple production and service-friendly construction of the connection of the air supply line to the buoyancy chamber. The finished air supply line with manifolds is mounted here at the other edge of the skirt and the manifolds are inserted into the associated duct, whereby the outlet of the manifold forms the air supply outlet to the duct chamber belonging to the duct.

Endnu en foretrukket udførelsesform ifølge opfindelsen er ejendommelig ved, at hvert opdriftskammers 3 forbindelse til luftforsyningsledningen har en kontraventil. Herved opnås en afspærring af luftforsyningsledningsforbindelsen mellem opdriftskamrene fra starten , således at man ved punktering af et opdriftskammer 5 helt undgår trykfald i de øvrige opdriftskamre. En til dette formål særlig velegnet kontraventil er en læbeventil som f.eks. er beskrevet i US 3 991 763. Sådanne ventiler benyttes også i forbindelse med lungeautomater for dykkerudstyr, og udmærker sig ved et særdeles ringe 10 modtryk i gennemstrømningsretningen.Yet another preferred embodiment of the invention is characterized in that the connection of each buoyancy chamber 3 to the air supply line has a non-return valve. This results in a shut-off of the air supply line connection between the buoyancy chambers from the start, so that when puncturing a buoyancy chamber 5, pressure drops in the other buoyancy chambers are completely avoided. A particularly suitable non-return valve for this purpose is a lip valve, e.g. is described in US 3 991 763. Such valves are also used in connection with lung apparatus for diving equipment, and are distinguished by a very low back pressure in the flow direction.

Fremgangsmåden, som nævnt i indledningen, er ejendommelig ved, at luftforsyningsledningen fyldes med vand efter opblæsning af flydespærringen, hvorved op-driftskamrene afspærres fra hinanden, og det undgås at 15 punktering af ét opdriftskammer medfører tømning af alle opdriftskamrene. Herved opnås, som ved kontraventilen, en afspærring af luftforsyningsledningen mellem opdriftskamrene fra starten og dermed undgås trykfald i de øvrige opdriftskamre ved punktering af et enkelt af 20 disse. Afspærringen opnås ved, at det vand, der er fyldt i luftforsyningsledningen, fungerer som vandlås for de enkelte opdriftskamres luftforsyningsledningsforbindelser.The process, as mentioned in the preamble, is peculiar in that the air supply line is filled with water after inflating the flow barrier, thus separating the operating chambers and preventing puncturing of one buoyancy chamber by emptying all the buoyancy chambers. As a result of this, as with the check valve, an air supply line between the buoyancy chambers is obtained from the start and thus the pressure drop in the other buoyancy chambers is avoided by puncturing one of these. The shut-off is achieved by the water filled in the air supply line acting as a water trap for the individual buoyancy chambers air supply line connections.

Opfindelsen forklares i det følgende nærmere ved 25 hjælp af nogle udførelsesformer under henvisning til tegningen, på hvilken fig. 1 er et sidebillede af en flydespærring ifølge opfindelsen vist i brugsstilling, fig. 2 i større skala et grenrørs indføring i 30 kanaludmundingen, idet den ene gummidug for overskueligheden er fjernet, fig. 3 som fig. 2 en udførelsesform, hvor grenrøret er ført helt op i opdriftskammeret og forsynet med en kontraventil, og 35 fig. 4 et snit langs linien I-I i fig. 2.BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be explained in more detail with reference to the accompanying drawings, in which: FIG. 1 is a side view of a float barrier according to the invention shown in use; FIG. 2 shows, on a larger scale, the insertion of a manifold into the duct opening, the one rubber cloth being removed for clarity; FIG. 3 as FIG. 2 shows an embodiment in which the manifold is fully inserted into the buoyancy chamber and provided with a non-return valve, and FIG. 4 is a section along line I-I of FIG. 2nd

4 spærringen omfatter langs den ene kant 5 af flydespærringen udformede opdriftskamre 1, og fra disse i brugsstillingen nedad forløbende kanaler 8. Under opdriftskamrene 1 ligger et skørt 2. Dette skørt har 5 forstærkninger 10 langs den nedre kant for fastgørelse af en ballastkæde 3 ved hjælp af fastgørelsesorganer 11. Denne ballastkæde 3 tjener på kendt vis til at fastholde flydespærringen i en i det væsentlige lodret position i vandet. En luftforsyningsledning 4 med 10 grenrør 7 er befæstiget til ballastkæden 3. Grenrøret 7 stikker op i kanalen 8 til opdriftskammeret l.4 the barrier comprises buoyant chambers 1 formed along one edge 5 of the flow barrier and from these downwardly extending channels 8. Under the buoyancy chambers 1 lies a skirt 2. This skirt has 5 reinforcements 10 along the lower edge for securing a ballast chain 3 by means of of fasteners 11. This ballast chain 3 serves in the known manner to hold the float barrier in a substantially vertical position in the water. An air supply line 4 with 10 manifolds 7 is attached to the ballast chain 3. The manifold 7 projects into the duct 8 of the buoyancy chamber 1.

Funktionen af den i fig. 1 viste udførelsesform ifølge opfindelsen forklares i det følgende under hen-15 visning til fig. 2, hvor visse dele er udeladt af overskuelighedshensyn. Opblæsning af opdriftskammeret l sker med trykluft via luftforsyningsledningen 4 og grenrøret 7. Fra starten vil vandniveauet i kanalen være ved vandlinieniveauet c. Efterhånden som trykket 20 i opdriftskammeret stiger, vil niveauet falde og til slut nå niveauet a ved kanalens udmunding, hvorefter yderligere trykstigning vil medføre udslip af luft via kanalen. Efter opblæsning, vil vandniveauet i kanalen ligge ved a. Hvis et kammer punkterer, vil trykket 25 over vandet i kanalen falde, og derved stiger vandet op i kanalen. Når vandet når niveauet b, løber vandet ned i luftforsyningsledningen og afspærrer således forbindelsen mellem opdriftskamrene, hvorefter vandet i kanalen for det punkterede opdriftskammer kan stige op til 30 vandlinien c, hvorved trykket ved udmundingen bliver det samme som i vandet omkring flydespærringen i dette niveau. Kort sagt, ved punktering af ét kammer falder trykket i de øvrige kamre fra vandtrykket ved a til vandtrykket ved b. Ved benyttelse af fremgangsmåden 35 ifølge opfindelsen undgås dette trykfald, idet den vandfyldte luftforsyningsledning spærrer for luftover-The function of the device shown in FIG. 1 according to the invention is explained below with reference to FIG. 2 where certain parts are omitted for the sake of clarity. Inflammation of the buoyancy chamber 1 takes place with compressed air via the air supply line 4 and the manifold 7. From the beginning, the water level in the duct will be at the waterline level c. cause leakage of air through the duct. After inflation, the water level in the duct will be at a. If a chamber is punctured, the pressure 25 over the water in the duct will decrease, thereby raising the water in the duct. When the water reaches level b, the water flows down into the air supply line, thus blocking the connection between the buoyancy chambers, whereupon the water in the channel of the punctured buoyancy chamber can rise up to the water line c, whereby the pressure at the outlet becomes the same as in the water around the flow barrier in this level. In short, by puncturing one chamber, the pressure in the other chambers drops from the water pressure at a to the water pressure at b. When using the method 35 of the invention, this pressure drop is avoided, as the water-filled air supply conduit blocks the air supply.

5 førsel fra de intakte kamre til det punkterede kammer.5 passes from the intact chambers to the punctured chamber.

Ved betragtning af beskrivelsen ovenfor vil det ses, at det, bortset fra ved benyttelse af fremgangsmåden ifølge opfindelsen, er uvæsentligt, at grenrøret 7 stikker 5 op nedefra. Afspærringen er bestemt alene af niveauet b for luftforsyningsledningens udmunding.In view of the description above, it will be seen that, except by using the method of the invention, it is not essential that the manifold 7 protrude from below. The barrier is determined solely by the level b of the outlet of the air supply line.

Ved den i fig. 3 viste udførelsesform er afspærring mellem kamrene 1 sikret fra starten ved hjælp af en kontraventil 9 monteret på luftforsy-10 ningsforbindelsen 7 til hvert kammer 1. Det er ved denne udførelsesform uden betydning, hvor luftforsyningsledningen er anbragt selvom den i fig. 3 er vist anbragt ved skørtet 2's nedre kant 6.In the embodiment shown in FIG. 3, interlocking between the chambers 1 is secured from the start by means of a check valve 9 mounted on the air supply connection 7 to each chamber 1. In this embodiment, it is of no importance where the air supply line is arranged even though in FIG. 3 is shown at the lower edge 6 of the skirt 2.

Med de beskrevne flydespærringer gives mulighed 15 for en hurtigere opblæsning af flydespærringerne ved benyttelse af et højere tilgangstryk. Kanalerne sikrer i den forbindelse, at overtrykket i opdriftskammeret 1 ikke overstiger trykforskellen mellem opdriftskammeret 1 og udmundingen af kanalen 8.With the aforementioned flow barriers, option 15 is provided for a faster inflation of the flow barriers by using a higher supply pressure. In this connection, the channels ensure that the overpressure in the buoyancy chamber 1 does not exceed the pressure difference between the buoyancy chamber 1 and the outlet of the channel 8.

20 Ved fremgangsmåden ifølge opfindelsen kan fyld ning af luftforsyningsledningen med vand enten ske ved at pumpe vand ind i luftforsyningsledningen eller ved at stikke luftforsyningsledningens ende ned i vandet og lade vandet strømme ind af sig selv, idet luften i 25 luftforsyningsledningen undslipper via udmundingerne til opdriftskamrene og bobler op fra kanaludmundingerne.In the method according to the invention, filling the air supply line with water can be done either by pumping water into the air supply line or by plugging the end of the air supply line into the water and allowing the water to flow by itself, as the air in the air supply line escapes through the outlets to the buoyancy chambers and bubbles up from the channel openings.

Der er mange variationsmuligheder for en flydespærring ifølge opfindelsen, fx kan luftforsyningsled-30 ningen fremføres langs overkanten, når blot udmundingen for det enkelte opdriftskammer befinder sig i kanalen for det pågældende kammer. Udmundingen for de til kammeret hørende kanaler kan også være beliggende i et vilkårligt niveau på flydespærringen, der blot skal 35 ligge under opdriftskammeret, fx kan den ene gummidug 13 eller 14 slutte over den neder s te kant 6 afThere are many variation options for a flow barrier according to the invention, for example, the air supply line can be advanced along the top edge, if only the outlet of the individual buoyancy chamber is in the channel of that chamber. The outlet of the ducts belonging to the chamber may also be located at any level on the flow barrier, which should only lie below the buoyancy chamber, for example, one rubber tab 13 or 14 may end over the lower edge 6 of
