Description

Die Erfindung bezieht sich auf eine Auftriebshilfe für Wasserfahrzeuge nach dem Oberbegriff des Anspruchs 1.The invention relates to a buoyancy aid for watercraft after Preamble of claim 1.

Eine Auftriebshilfe für Wasserfahrzeuge in Seenot mit Schwimmsäcken ist aus der GB-PS 1 455 681 bekannt. An einem Schiff sind außenbords mehrere Behälter mit aufblasbaren Schwimmsäcken angeordnet.A buoyancy aid for watercraft in distress with swimming bags is out of the GB-PS 1 455 681 known. There are several containers on the outboard of a ship inflatable swimming bags arranged.

Aus der CH-PS 154 689 ist es bei einem Unterseeboot bekannt, ebenfalls an der Außenseite aufblasbare Schwimmsäcke vorzusehen, die durch Netze, die die Schwimmsäcke umspannen, gesichert sind.From CH-PS 154 689 it is known for a submarine, also on the The inflatable swimming bags provided by nets that cover the outside Cover swimming bags, are secured.

Sowohl die Armatur als auch der in einem Raum befestigte Hacken legen den Schwimmsack ortsfest fest. Dieses Prinzip eignet sich zum weitgehenden Ausfüllen vollkommen leerer Schiffsräume. Sind jedoch Schiffsräume mit Einbauten, wie Schaltschränke, Leitungen, Ventile versehen, so behindern diese die Ausdehnung der Schwimmsäcke, so daß der erforderliche Füllungsgrad des Raumes mit Schwimmsäcken nicht erreicht wird. Ausgehend von diesem Stand der Technik liegt der Erfindung die nachstehende Aufgabe zugrunde. GB 148 295 A discloses a buoyancy aid for watercraft in distress Swimming bags arranged inside the vessel and passed through a Gas source are inflatable, the swimming bags with the watercraft through an inflation valve and a net with bracing arranged on it Hoes are connected. Both the tap and the one fastened in a room Choes fix the swimming bag in place. This principle is suitable for the most part Filling in completely empty ship rooms. However, they are ship rooms with fittings such as switch cabinets, lines, valves, they hinder them the expansion of the swimming bags, so that the required degree of filling of the Room with swimming bags is not reached. Based on this state of the Technology, the invention is based on the following object.

Der Erfindung liegt die Aufgabe zugrunde, bei havarierten Wasserfahrzeugen mit Wassereinbruch für einen großen Füllungsgrad durch Auftriebskörper zu sorgen, damit eine volle Manövrierfähigkeit vorliegt.

Die Geometrie der Schwimmsäcke ist auf einige, wenige Grundformen beschränkt, z.B. Ellipsoide, Kugeln oder Zylinder und auf eine Größe, die ein optimales, selbständiges Füllen der Leerräume durch die Säcke ermöglicht. Die Säcke werden bei Bedarf aufgeblasen, wenn sie voll sind, automatisch verschlossen und von der Basis - dem Packbehälter - getrennt. Nur gehalten an einer langen Leine können sie in dem leckgeschlagenen Raum dorthin wandern, wo noch Platz ist. Die Vorteile sind ein guter Füllungsgrad in Verbindung mit oder ohne aufgeblasenen, ortsfesten Säcken und ein einfaches Verfahren. Für die Schwimmsäcke findet ein konventionelles, festes Material Verwendung.The geometry of the swimming bags is limited to a few basic shapes, e.g. Ellipsoids, spheres or cylinders and to a size that is optimal, independent Allows to fill the empty spaces through the sacks. The bags are at Puffed up when they are full, automatically locked and inflated separated from the base - the packing container. They can only be kept on a long line in the leaked room hike where there is still space. The advantages are a good degree of filling in Connection with or without inflated, stationary bags and a simple one Method. A conventional, solid material is used for the swimming bags.

Um zu verhindern, daß die Schwimmsäcke oder die Leinen an unerlaubten Plätzen sind oder kommen, werden diese Plätze, Orte, Wege, z. B. Ruderwege, mit Leitnetzen gesichert.To prevent the swimming bags or the lines from being used in unauthorized places are or are coming, these places, places, paths, e.g. B. rowing routes, with guidance networks secured.

Die erfindungsgemäßen Schwimmsäcke inklusive ihrer Fesselung gewährleisten bei einem havarierten Wasserfahrzeug einen großen Auftrieb. Die Schwimmsäcke können eine beliebige Form aufweisen und auch unterschiedlich groß sein, um den zur Verfügung stehenden Raum optimal auszufüllen. Das Wasserfahrzeug ist unter Einschränkung des Lecks voll manöverierfähig und kann auch seine Fahrt beibehalten. Ein Stillegen des Wasserfahrzeugs ist nicht notwendig.The swimming bags according to the invention including their bondage ensure a big buoyancy for a damaged watercraft.

Diese Befestigungsart ist also nur bei einem kleinen Schwimmsack 40 möglich, der im dargestellten aufgeblasenen Zustand symmetrisch zu seinem Behälter 8 steht und nur in Richtung des Pfeiles 43 in der Symmetrielinie 11 belastet wird. Damit sind unkontrollierte Spannungspitzen im Werkstoff des Schwimmsackes 40 vernachlässigbar.A swimming bag 40 which is substantially smaller than the swimming bags 4, 30 5 is by vulcanization 39 or gluing to side surfaces 41 and / or attached to the bottom 42 of a container 38. This type of attachment is only for a small swimming bag 40 possible, the inflated state shown is symmetrical to its container 8 and only in the direction of arrow 43 in the line of symmetry 11 is loaded. So there are uncontrolled voltage peaks negligible in the material of the swimming bag 40.

Der Schwimmsack 50 ist über eine einzige Leine 52 und eine elastische, sackseitige Leinenhalterung 53 mit einem Staubehälter 54 verbunden.The swimming bag 50 is on a single line 52 and an elastic, bag-side Line holder 53 connected to a storage container 54.

Spanten sind mit 56, 57 und eine Schiffswand mit 58 bezeichnet.Frames are marked with 56, 57 and a ship's wall with 58.

Ein in Richtung des Pfeiles 59 verschiebbares Ruder 60 ist in der gezeichneten Lage mit einem Leitnetz 61 gesichert.A rudder 60 which can be displaced in the direction of arrow 59 is in the position shown secured with a control network 61.

Die Behälter 34, 81, 82 für die ortsfesten Schwimmsäcke 30, 40, 44 und die Behälter 8, 54 für die ortsvariablen Schwimmsäcke 4, 50 sind sowohl auf den Spanten 56, 57 als auch an einem schiffsfesten Einbau 62 befestigt.The containers 34, 81, 82 for the stationary swimming bags 30, 40, 44 and the containers 8, 54 for the variable floating swimming bags 4, 50 are both on the frames 56, 57 and fixed to a ship-mounted installation 62.

Nach einer Havarie liegt die Lecköffnung 55 vor mit einem Wassereinbruch 3. Es werden dann, durch nicht dargestellte Sensoren gesteuert, die Schwimmsäcke 4, 30, 40, 44, 50 aufgeblasen. Die Schwimmsäcke 30, 44 hüllen die Leitnetze 61 so ein, daß das Ruder 60 funktionsfähig bleibt. After an accident, the leakage opening 55 is present with a water ingress 3. It are then controlled by sensors, not shown, the swimming bags 4, 30, 40, 44, 50 inflated. The swimming bags 30, 44 cover the guide nets 61 in this way a that the rudder 60 remains functional.

Der sonst freie Raum 51 wird weitgehend durch die Schwimmsäcke 4, 30, 50 ausgefüllt.The otherwise free space 51 is largely filled by the swimming bags 4, 30, 50.

Die ortsbeweglichen Schwimmsäcke 4, 50 wandern in die noch freien Zwischenräume 63, 64 zwischen den ortsfesten Schwimmsäcken 30, 40, 44 ein. Damit wird ein sehr großer Füllungsgrad durch die schwimmsäcke 4, 30, 44, 50 erreicht. Vorteilhaft ist, daß die Wanderungsbewegung der ortsbeweglichen Schwimmsäcke 4, 50 zu den noch freien Zwischenräumen 63, 64 selbständig erfolgt.The portable swimming bags 4, 50 migrate into the still free spaces 63, 64 between the stationary swimming bags 30, 40, 44. So that will A very high degree of filling is achieved with the floating bags 4, 30, 44, 50. Advantageous is that the movement of the portable swimming bags 4, 50 to the still free spaces 63, 64 takes place independently.

Vorteilhaft sind etwa 30% ortbewegliche Schwimmsäcke 4, 50. Diese ortsbeweglichen Schwimmsäcke 4, 50 haben auch noch den Vorteil, daß sie die Räume von geplatzten Schwimmsäcken einnehmen können, beispielsweise einem mit der Bezugszahl 65 angedeuteten Rest eines bei 66 aufgespiesten Schwimmsackes.About 30% of portable swimming bags 4, 50 are advantageous. These portable ones Swimming bags 4, 50 also have the advantage that they are the rooms of burst swimming bags, for example one with the reference number 65 indicated remainder of a swimming bag impaled at 66.
