Abstract

Installation for towing with the boat an enveloped iceberg respectively a resultant water-bag (1). The water-bag (1) has at least at one towing end a tow-bar (9) which is transversal with respect to the towing direction. On the tow-bar (9) are attached rolls (a, b ...) of loops (4) next to each other and used as flexible traction mechanisms. Tow neighbouring loops (4) of a row of loops are connected by another loop in order to form the following row of loops which comprises consequently one loop less until, after forming an acute-angled towing net (5), only one loop or more loops remain to attach the water-bag to a tow-boat. Thereby a uniform distribution of the traction force and a reduction of specific stress in the loop areas are obtained so that the problems of towing the water-bag are eliminated thereby making the towing operation possible with a reduced slide friction coefficient.

Description

Gleichmässige Zugkraftverteilung Uniform distribution of traction
Die Erfindung betrifft eine Vorrichtung für den Schlepp¬ transport eines umhüllten Eisberges bzw. einer Eisberg¬ umhüllung bzw. eines daraus entstehenden Wassersackes auf dem Wasserwege, mit zumindest an einem Schleppende des Wassersackes befestigten flexiblen Zugmitteln.The invention relates to a device for the towing transport of a covered iceberg or an iceberg covering or a water bag resulting therefrom by water, with flexible traction means attached to at least one towing end of the water bag.
Bevorzugt in solchen Ländern der Erde, in denen Wasser¬ mangel herrscht, sind Überlegungen darüber angestellt worden, Eisberge aus der Arktis bzw. Antarktis für die Trink- und Brauchwassergewinnung zu verwerten. Es hat sich herausgestellt, daß selbst bei Einsatz mehrerer und stärkster Schlepper soviele Schlepptage erforderlich sind, daß die Eisberge vor Erreichen der Zielländer voll¬ ständig abgeschmolzen sind. Aus diesem Grunde ist vorge¬ schlagen worden, in der Arktis und/oder Antarktis trei- bende Eisberge vorgegebener Größe in wasserdichte flexible Umhüllungen einzupacken, dann das miteingepackte See¬ wasser bzw. Salzwasser aus den Umhüllungen herauszupum¬ pen und die Umhüllungen anschließend zu verschließen, so daß dann die in Richtung Äquator treibenden umhüllten Eisberge nach teilweisem oder vollständigem Abschmelzen sowie Erreichen eines bestimmten Breitengrades als Wasser¬ säcke mittels Schlepper in das bzw. die Zielländer trans¬ portiert werden können. Als Umhüllungen für die Eisberge kommen Kunststoffs cke aus Folie oder Gewebesäcke mit Gummi- oder Kunststoffbeschichtung in Frage. In einem bekannten Fall findet als Umhüllung ein Kunststoffsack Verwendung, der einen gleichsam oben liegenden Schwimm¬ ring und im übrigen vertikale Stabilisierungsrippen aufweist, die sämtlich aufblähbar sind. Der zunächst unten und oben offene Kunststoffsack soll von Hubschrau¬ bern über den betreffenden Eisberg gestülpt werden. Anschließend muß der Kunststoffsack bodenseitig unter Wasser gleichsam zusammengebunden bzw. zusammengezogenIn countries in the world where there is a lack of water, considerations have been made of using icebergs from the Arctic or Antarctic for drinking and industrial water production. It has been found that, even when using several and strongest tugs, so many towing days are required that the icebergs have completely melted off before reaching the destination countries. For this reason, it has been proposed to pack icebergs of a predetermined size drifting in the Arctic and / or Antarctic into waterproof flexible casings, then to pump the sea water or salt water that is also packed out of the casings and then to seal the casings, so that after the partial or complete melting and reaching a certain degree of latitude, the enveloped icebergs driving in the direction of the equator can be transported as water sacks to the destination country or countries by means of a tractor. Plastic envelopes made of film or fabric bags with rubber or plastic coating can be used as coverings for the icebergs. In a known case, a plastic bag is used as the covering, which has a floating ring, as it were, and vertical stabilizing ribs, which are all inflatable. The plastic sack, which is initially open at the top and bottom, is to be put over the relevant iceberg by helicopters. Then the plastic sack must be tied or contracted underwater at the bottom
OM werden. Ein derartig umhüllter Eisberg weist einen er¬ heblichen Tiefgang selbst nach teilweisem oder vollstän¬ digem Abschmelzen auf. Denn dafür sorgen die aufgeblähten Vertikalrippen. Ein solcher Kunststoffsack läßt sich wegen seines Tiefganges und des daraus resultierenden erheblichen Wasserwiderstandes nur schwer abschleppen und im übrigen nicht durch die Untiefen vor den in Frage kommenden Küstengebieten transportieren (vgl. US-PS 32 89 4OM become. An iceberg encased in this way has a considerable draft even after partial or complete melting. Because the inflated vertical ribs ensure that. Such a plastic bag is difficult to tow because of its draft and the resulting considerable water resistance and, moreover, it cannot be transported through the shallows in front of the coastal areas in question (cf. US Pat. No. 3,289,4
Außerdem kennt man ein Verfahren zum Transport und zur Lagerung von Trink- und Brauchwasser, wobei das Wasser in Sammelbecken mit Entleerungseinrichtungen gesammelt und flexiblen zum Schleppen hinter Schiffen eingerich¬ teten Unterwasserfahrzeugen in der Ausführungsform von Tankschläuchen zugeleitet wird. Die Tankschläuche werden zu wasserarmen Gebieten geschleppt, dort gelagert und entleert. Derartige Maßnahmen sind jedoch zum Einpacken von Eisbergen ungeeignet. Darüber hinaus sind die Vor¬ richtungen für den Schlepptransport unbefriedigend, weil die flexiblen Zugmittel zentral an die Tankschläuche angreifen. Daraus resultiert ein punktartiger Zugkraft¬ angriff, der zu einer extrem hohen Beanspruchung der Tankschläuche führt und folglich für Großwassertransporte ungeeignet ist, will man Beschädigungen der Tankschläuche vermeiden. Das gilt im übrigen auch unter Berücksichtigung der Tatsache, daß derartige Tankschläuche aufgrund ihres wurstartigen bzw. zeppelinförmigen Querschnitts einen ebenfalls relativ starken Tiefgang und folglich hohen Wasserwiderstand aufweisen (vgl. CH-PS 477 606). Tat¬ sächlich ist die Abschlepptechnik nicht nur bei derar- tigen Tankschläuchen, sondern allgemein bei der Eisberg¬ verfrachtung problematisch. - Hier setzt die Erfindung ein. Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung für den Schlepptransport einer Eisbergumhüllung bzw. eines daraus entstehenden Wassersacks auf dem Wasserwege der eingangs beschriebenen Art zu schaffen, welche sich durch eine besonders gleichmäßige Zugkraftverteilung unter Berücksichtigung eines äußerst geringen Gleitwider¬ standes in bezug auf den sich bildenden Wassersack aus¬ zeichnet.In addition, a method is known for the transport and storage of drinking and industrial water, the water being collected in collecting basins with emptying devices and being fed flexibly in the embodiment of tank hoses, designed for towing behind ships, in the embodiment of tank hoses. The tank hoses are towed to arid areas, where they are stored and emptied. However, such measures are unsuitable for packing icebergs. In addition, the devices for towing are unsatisfactory because the flexible traction means act centrally on the tank hoses. This results in a point-like tensile force attack, which leads to an extremely high load on the tank hoses and is consequently unsuitable for transporting large water if one wants to avoid damage to the tank hoses. This also applies, taking into account the fact that tank hoses of this type, due to their sausage-like or zeppelin-shaped cross-section, also have a relatively strong draft and consequently high water resistance (cf. CH-PS 477 606). In fact, the towing technique is problematic not only in the case of such tank hoses, but generally in the delivery of icebergs. - This is where the invention begins. The invention has for its object to provide a device for the towing transport of an iceberg envelope or a water bag resulting therefrom on the waterway of the type described above, which is characterized by a particularly uniform distribution of traction, taking into account an extremely low sliding resistance in relation to the distinguished forming water bag.
Diese Aufgabe löst die Erfindung bei einer gattungsge- mäßen Schleppvorrichtung dadurch, daß der Wassersack an dem betreffenden Schleppende einen quer zur Schlepprich¬ tung verlaufenden Schleppholm aufweist und an dem Schlepp¬ holm als flexible Zugmittel n Schlaufen in Reihe neben¬ einander befestigt sind und jeweils zwei benachbarte Schlaufen dieser Schlaufenreihe von einer weiterenThis object is achieved by the invention in a generic towing device in that the water bag at the towing end in question has a towing bar extending transversely to the towing direction and n loops are fastened to the towing bar as flexible traction means in series and two each Adjacent loops of this row of loops from another
Schlaufe unter Bildung einer nächsten Schlaufenreihe mit n-1 Schlaufen eingebunden sind und so fort, bis unter Bildung eines spitzwinklig zulaufenden Schlepp¬ netzes n-x oder lediglich eine Schlaufe zum Anschluß des Wassersackes an einen Schlepper übrig bleiben. - Diese Maßnahmen der Erfindung haben zunächst einmal zur Folge, daß der Schleppholm bzw. die daran angrei¬ fenden Schleppkräfte für eine Wassersackbildung mit äußerst geringem Tiefgang Sorge tragen, so daß ein gleichsam flunderartiger Wassersack mit einem äußerst geringen Wasserwiderstand und folglich Gleitwiderstand entsteht. Zugleich wird für eine über die Länge des Schleppholms angreifende Zugkraftverteilung Sorge ge¬ tragen, die aufgrund des erfindungsgemäßen Aufbaus des Schleppnetzes verhältnismäßig gleichmäßig ist. Eine nahezu gleichmäßige Zugkraftverteilung wird durch eine Verjüngung des Schlepp- bzw. Schlaufennetzes bis zu 30 erreicht. Aufgrund der erfindungsgemäßen MaßnahmenLoops are formed to form a next row of loops with n-1 loops and so on until n-x or only one loop remains for the connection of the water bag to a tractor, forming a trailing netting. - First of all, these measures of the invention have the consequence that the towing bar or the towing forces acting thereon ensure a water bag formation with an extremely shallow draft, so that, as it were, a flounder-like water bag with extremely low water resistance and consequently sliding resistance is produced. At the same time, care is taken to ensure that the tensile force is distributed over the length of the towing bar and is relatively uniform due to the structure of the towing net according to the invention. An almost even distribution of traction is achieved by tapering the towing or loop network up to 30. Because of the measures according to the invention
OM läßt sich nunmehr der Wassersack, ohne daß Beschädigungen zu fürchten sind, mit lediglich einem einzigen Schlepper verhältnismäßig schnell zu seinem Ziellaπd transportieren. Insoweit werden die Probleme uin. die Eisbergverfrachtung sowohl in transporttechnischer als auch in finanzieller Hinsicht gelöst, zumal der Abschleppaufwand in maschi¬ neller und energiemäßiger Hinsicht äußerst gering gehal¬ ten werden kann. Im ganzen ermöglicht die erfindungsge¬ mäße Schleppvorrichtung eine besonders wirtschaftliche und funktionsgerechte Verfrachtung von umhüllten Eis¬ bergen bzw. daraus entstehenden Wassersäckεn in die je¬ weiligen Zielländer, wobei aufgrund des geringen Tief¬ ganges selbst Untiefen vor den in Frage kommenden Küsten¬ gebieten unschwer überfahren werden können. - Darin sind die wesentlichen durch die Erfindung erreichten Vorteile zu sehen.OM the water bag can now be transported relatively quickly to its target with only a single tractor without fear of damage.

Weitere erfindungsωesentliche Merkmale sind im folgenden aufgeführt. So ist nach bevorzugter Ausführungsform der Schleppholm als Gliederholm ausgebildet und in eine Mehr- zahl von Holmgliedern mit Schlaufenlöchern zum Anschluß von n Schlaufen der ersten Schlaufenreihe unterteilt. Die Gliedausbildung des Schleppholms sorgt für seine einwandfreie Anpassung an die Wasseroberfläche. Außer¬ dem wird dadurch in bezug auf den Schleppholm eine er- wünschte Flexibilität erreicht. Weiter sieht die Erfin¬ dung vor, daß der Wassersack an dem betreffenden Schlepp¬ ende eine wulstartige Randverstärkung aus Leder, Gummi oder Kunststoff aufweist und die Holmglieder diese Rand¬ verstärkung umfassen oder das Sackmaterial auf der Ober- seite und Unterseite umfassen und bei angreifenden Schlepp¬ kräften in Schlepprichtung gegen die Randverstärkung auf¬ laufen. Auf diese Weise werden hohe spezifische Belastun¬ gen infolge der angreifenden Schleppkräfte sowohl zwischenFurther features essential to the invention are listed below. Thus, according to a preferred embodiment, the towing bar is designed as a link bar and is divided into a plurality of bar links with loop holes for connecting n loops of the first row of loops. The limb formation of the towing bar ensures its perfect adaptation to the water surface. In addition, a desired flexibility is achieved in relation to the towing bar. The invention further provides that the water bag has a bead-like edge reinforcement made of leather, rubber or plastic at the relevant towing end and the spar members comprise this edge reinforcement or include the sack material on the top and bottom and when the towing is attacking ¬ forces in the towing direction against the edge reinforcement. In this way, high specific loads due to the attacking towing forces between both
