Description

Denne oppfinnelse vedrører en anordning for å tilveiebringe et oljevern både i stillestående og rennende vann. This invention relates to a device for providing an oil barrier both in stagnant and flowing water.

Anordninger av denne art er kjent. En kjent løsning fo-reslår f.eks. benyttelsen av skjørt som holdes i vannet ved hjelp av flottører. Ved slike anordninger finnes en tendens til overskylling i stående vann og til underskylling i rennende vann. Devices of this kind are known. A known solution suggests e.g. the use of skirts held in the water by means of floats. With such devices, there is a tendency to over-rinse in standing water and to under-rinse in running water.

En ytterligere kjent anordning forutsetter anvendelsen A further known device presupposes the application

av en enkel slange (system Dr. Stauber). Denne slange fylles delvis med vann, og dermed kan neddypningen i vannet reguleres. Ved urolig vannspeil består imidlertid tendensen for ujevn vann-fordeling i slangen og derfor ujevn neddypning med fare for under- eller overskylling. of a simple hose (system Dr. Stauber). This hose is partially filled with water, and thus the immersion in the water can be regulated. However, in case of an unstable water level, there is a tendency for uneven water distribution in the hose and therefore uneven immersion with the risk of under- or over-flushing.

Hensikten med denne oppfinnelse er derfor å tilveiebringe en anordning for dannelse av et oljevern med i det minste en slange som opphever de nevnte ulemper og som er egnet til bruk både i stående og i rennende vann. The purpose of this invention is therefore to provide a device for forming an oil guard with at least one hose which eliminates the aforementioned disadvantages and which is suitable for use both in standing and running water.

Denne oppgave løser en anordning av den innledningsvis nevnte art som utmerker seg ved at anordningen i lengderetningen er oppdelt i to atskilte kammere, hvorav i brukstilstand det nederste kammer er fullstendig fylt med vann og det øverste kammer er fullstendig fylt med luft og det på slangen direkte eller indirekte er anbrakt ører for fastgjøring av anordningen til holdetau. This task solves a device of the kind mentioned at the outset, which is distinguished by the fact that the device is divided in the longitudinal direction into two separate chambers, of which in use the lower chamber is completely filled with water and the upper chamber is completely filled with air and that on the hose directly or indirectly, lugs are placed for attaching the device to the holding rope.

På tegningen er det vist skjematisk to utførelseseksempler av oppfinnelsesgjenstanden. The drawing shows schematically two embodiments of the object of the invention.

Tegningen viser på fig. 1 en utførelsesform til anvendelse særlig for stillestående farvann, og The drawing shows in fig. 1 an embodiment for use in particular for stagnant waters, and

fig. 2 en utførelsesform for anvendelse særlig for rennende vann. fig. 2 an embodiment for use in particular for running water.

På fig. 1 er anordningen for dannelse av et oljevern betegnet i sin helhet med 1. In fig. 1, the device for forming an oil shield is denoted in its entirety by 1.

Den forurensede vannflate befinner seg til venstre og den rene vannflate til høyre for anordningen (ifølge figuren). På den forurensede vannflate flyter et oljesjikt 0 på vannet W. The contaminated water surface is to the left and the clean water surface to the right of the device (according to the figure). On the polluted water surface, an oil layer 0 floats on the water W.

Anordningen 1 består av en sylindrisk slange 2 av plast-materiale med en skillevegg 3 som deler slangens innerrom i to kammere 4 og 5. Det nedre kammer 4 er fullstendig fylt med vann, mens det øvre kammer 5 er fylt med luft eller gass. Anordningen 1 stikker alltid ribe dypere ned i vannet W enn skil- leveggens 3 nivå. I det illustrerte tilfelle er skilleveggen 3 anordnet på midten av slangen 2, slik at de.to kammere 4,5 er like store. På ytterveggen av slangen 2er det anordnet flere ører 6 for gjennomføring av holde- hhv. avstivningstau. The device 1 consists of a cylindrical hose 2 made of plastic material with a dividing wall 3 which divides the inner space of the hose into two chambers 4 and 5. The lower chamber 4 is completely filled with water, while the upper chamber 5 is filled with air or gas. The device 1 always sticks deeper into the water W than the level of the dividing wall 3. In the illustrated case, the dividing wall 3 is arranged in the middle of the hose 2, so that the two chambers 4,5 are the same size. Several lugs 6 are arranged on the outer wall of the hose 2 for holding or bracing ropes.

Oppdelingen i to kammere tillater imidlertid også å fylle However, the division into two chambers also allows filling

i det minste et kammer med et visst overtrykk for derved å opp-nå en ytterligere stivhet i anordningen, slik at denne ligger roligere i vannet. at least a chamber with a certain overpressure in order to thereby achieve further rigidity in the device, so that it lies more calmly in the water.

Varianten ifølge fig. 2 viser igjen anordningen i tverrsnitt og er i dette tilfelle betegnet med 10. The variant according to fig. 2 again shows the device in cross-section and is in this case denoted by 10.

Denne utførelse er særlig hensiktsmessig for rennende vann og har som særlig kjennetegn to ulike store kammere 14,15. Det minste kammer 15 er fylt med luft og ligger oventil og det stør-ste kammer 14 ligger under og er fylt med vann. Det i retning av pilen F strømmende vann treffer således anordningen 10 og lar de nedre vannsjikt passere uhindret, mens oljeteppet og de øvre vannsjikt som tildels inneholder olje emulgert med vann, stues opp, hvorved utskillelsen av de emulgerte stoffer begun-stiges. Oljen som uten videre som følge av sin mindre egenvekt flyter opp, holdes tilbake. Den strømningsriktige form er for-delaktig ved at ingen for store trykkrefter utøves fra det rennende vann mot anordningen. This design is particularly suitable for running water and has as a particular characteristic two different large chambers 14,15. The smallest chamber 15 is filled with air and is located above and the largest chamber 14 is located below and is filled with water. The water flowing in the direction of arrow F thus hits the device 10 and allows the lower water layers to pass unimpeded, while the oil blanket and the upper water layers, which partly contain oil emulsified with water, are stored, whereby the excretion of the emulsified substances is favored. The oil, which immediately floats up as a result of its lower specific gravity, is held back. The flow-correct shape is advantageous in that no excessive pressure forces are exerted from the flowing water against the device.

Anordningens tverrsnittsform er omtrent pæreformet og omfatter en skillevegg 13 som er anordnet i den øvre halvdel. En ytterligere variant som gir omtrent samme tverrsnittsform, består av en liten slange som danner det øvre kammer og en andre nedre slange med større tverrsnitt som danner det nedre kammer. De to slanger kan være sammensveiset f.eks. i lengderetningen langs den felles mantellinje. The cross-sectional shape of the device is approximately pear-shaped and comprises a partition wall 13 which is arranged in the upper half. A further variant, which gives approximately the same cross-sectional shape, consists of a small tube forming the upper chamber and a second lower tube with a larger cross-section forming the lower chamber. The two hoses can be welded together, e.g. in the longitudinal direction along the common mantle line.

Det er vesentlig, spesielt ved de sistnevnte utforminger av anordningen og særlig i rennende vann at ørene for holdetauene er anordnet riktig. Til dette tjener særlig ørene 16 It is essential, especially in the latter designs of the device and particularly in running water, that the ears for the holding ropes are arranged correctly. The ears are especially useful for this 16

De ytterligere ører 16 tjener også til fastgjøring og av-stivning av anordningen ved hjelp av tau. Også her kan avstiv-ningen av anordningen forøkes ved hjelp av overtrykk i et av kamrene 14 eller 15. The further lugs 16 also serve to fasten and stiffen the device by means of ropes. Here too, the stiffening of the device can be increased by means of excess pressure in one of the chambers 14 or 15.

Anordningens diameter er forskjellig etter anvendelsesfor-målet, men i det minste omtrent 5 0 cm . The diameter of the device varies according to the intended use, but at least approximately 50 cm.

Foruten de viste utførelsesformer kan "tokammerprinsippet" også oppnås ved hjelp av to slanger med forskjellig diameter som er anordnet i hverandre. Besides the embodiments shown, the "two-chamber principle" can also be achieved by means of two hoses of different diameters which are arranged inside each other.
