Description

7808598-2 -2- Fig. 2 visar en planvy av anordningen enligt Pig. 1. 7808598-2 -2- Fig. 2 shows a plan view of the device according to Fig. 1.

I Figurerna visas den främre delen av en sjögående farkost 10, vid vilken den ovan angivna oljeupptagningskassetten ll är lösbart anbragt. Oljeupp- tagningskassetten ll utgöres av en flytkropp, uppbyggd av två parallella pontoner 12 och centralt däremellan anbragta bandtransportörer 13, 14 för oljeuppsamling från vattenytan. Farkosten 10 är avsedd att drivas genom det oljetäckta vattnet med transportörernas 13, 14 band i rörelse. 15 be- tecknar härvid för farkostens drift anordnade propellrar. Transportörerna kan på det i Figurerna visade sättet innefatta på olika sätt i förhållande till pontonerna 12 orienterade transportörer. Sålunda har 1 den visade ut- föringsformen de i färdriktningen främst belägna transportörerna 13 orien- terats snedställda i farkostens 10 rörelseriktning. Transportörernas 13 band har därtill gjorts perforerade för uppsamling av tjockoljespill under det att den akterut på kassetten ll upptagna transportören 14 orienterats vertikalt i och för upptagning av tunnolja. Med.l6 är betecknat en oljeupp- samlingsbehållare. Det är emellertid underförstått, att även på annat sätt utformade organ på kassetten ll kan vara anordnade för oljeupptagningen.The figures show the front part of a sea-going vessel 10, in which the above-mentioned oil collection cassette 11 is releasably mounted. The oil collection cassette 11 consists of a floating body, built up of two parallel pontoons 12 and belt conveyors 13, 14 arranged centrally between them for collecting oil from the water surface. The vehicle 10 is intended to be driven through the oil-covered water with the belts of the conveyors 13, 14 in motion. 15 denotes in this case propellers arranged for the operation of the vessel. The conveyors can, in the manner shown in the Figures, comprise conveyors oriented in different ways in relation to the pontoons 12. Thus, in the embodiment shown, the conveyors 13 located primarily in the direction of travel have been oriented obliquely in the direction of movement of the vessel 10. In addition, the belts of the conveyors 13 have been made perforated for collecting thick oil spills, while the conveyor 14 accommodated aft of the cassette 11 is oriented vertically in order to receive thin oil. Med.l6 is denoted an oil collection container. It is understood, however, that means otherwise formed on the cassette 11 may also be provided for oil uptake.

Enligt uppfinningen är oljeupptagningskassetten ll lösbart anbragt vid far- kosten 10, företrädesvis vid dess främre ände. För detta ändamål har kasset- tens ll akterparti försetts med förankringsorgan, som vid den visade ut- föringsformen har givits formen av ett antal akterut från kassetten sig sträekande, från varandra åtskilda plåtar 17 eller liknande, vilka är före- nade medelst en tvärgående cylinderstång 18. I och för möjliggörande av lås- bar samverkan därmed har vid farkostens främre ände fästats en mottagande gaffel 19, vars spröt 20 är orienterade rakt uppåt och inbördes så placera- de, att de ingriper emellan kassettens ll plåtar 17 vid anslutningen av 3 kassetten ll till farkosten 10. Samtidigt har pontonernas 12 akterpartier -gjorts bakåt avsmalnande. Genom det sålunda angivna utförandet uppnås att kassetten ll kan följa vattnets rörelse oberoende av farkostens 10 rörelse- mönster, så att på kassetten anbragta transportörer alltid samlar upp oljan från vattnets ytskikt, där förorenings- eller oljekoncentrationen är stor. a För att underlätta transporten av kassetten på farkosten 10 kan den sist-' nämnda tänkas utförd med en vid det främre ändpartiet gjord överbyggnad 21, inuti vilken kassetten ll kan upptagas, såsom är visat med strecklinjemarke- ring i lig. 1. -:- É 7soss9a-2 Det är givetvis underförstått, att uppfinningen kan varieras inom ramen för de uppställda patentkraven. I stället för låsning medelst gripgaffel är det möjligt att använda olika typer av hakar eller andra för ändamålet lämpade snabbkopplingar emellan farkosten 10 och kassetten llt Förutsätt- ningen är dock, att utformningen därav är sådan, att kassetten ges en viss rörelsefrihet vid farkostens drivning oberoendenav farkostens rörelsemöns- ter. tAccording to the invention, the oil collection cassette 11 is releasably mounted at the vessel 10, preferably at its front end. For this purpose, the aft part of the cassette 11 has been provided with anchoring means, which in the embodiment shown have been given the shape of a number of stern from the cassette extending, spaced apart plates 17 or the like, which are joined by means of a transverse cylinder rod 18. In order to enable lockable co-operation therewith, a receiving fork 19 has been attached to the front end of the vessel, the rods 20 of which are oriented straight upwards and mutually positioned so that they engage between the plates 17 of the cassette 11 at the connection of the cassette 11. to the vessel 10. At the same time, the 12 stern sections of the pontoons have been made tapered backwards. By the design thus stated it is achieved that the cassette 11 can follow the movement of the water independently of the movement pattern of the vessel 10, so that conveyors arranged on the cassette always collect the oil from the surface layer of the water, where the pollution or oil concentration is high. In order to facilitate the transport of the cassette on the vessel 10, the latter can conceivably be made with a superstructure 21 made at the front end portion, within which the cassette 11 can be accommodated, as is shown by dashed line marking in lig. It is of course understood that the invention may be varied within the scope of the appended claims. Instead of locking by means of a gripping fork, it is possible to use different types of hooks or other quick couplings suitable for the purpose between the vessel 10 and the cassette llt. The condition, however, is that the design is such that the cassette is given some freedom of movement. movement patterns. t
