Description
Der Hebekörper gemäß der Erfindung besteht aus einer elastischen, sackförmigen Hülle 1 aus Polyäthylen oder einem anderen gasundurchlässigen Material.The lifting body according to the invention consists of an elastic, Sack-shaped envelope 1 made of polyethylene or another gas-impermeable material.
Diese Hülle 1 kann die in der Zeichnung dargestellte übliche Form, aber auch eine quadratische, rhombische oder andere polygonale Form aufweisen.This shell 1 can have the usual shape shown in the drawing, but also have a square, rhombic or other polygonal shape.
Die Hülle 1 ist unten an einem Rohrstutzen 2 befestigt. Dieser Rohrstutzen 2 besteht aus einem biegsamen Kunststoff und ist in seinem Inneren auf dem größten Teil seiner Länge mit einer Metallspirale 3 versehen, die sein Zusammendrücken verhindert. Das untere Ende des Rohrstutzens 2 trägt in einer Umstülpung ein ringförmiges Gewicht 4.The shell 1 is attached to a pipe socket 2 at the bottom. This pipe socket 2 consists of a flexible plastic and is on the largest inside Part of its length is provided with a metal spiral 3 which prevents it from being compressed. The lower end of the pipe socket 2 carries an annular weight in an eversion 4th
In die Hülle 1 wird Kohlensäure in festem Zustand (Trockeneis) in einer solchen Menge eingefüllt, daß nach dem Verdunsten die Hülle nicht prall gefüllt ist, sondern sich leicht an die jeweilige Form einer Anlagefläche anschmiegt (Fig. 3).In the shell 1 carbonic acid is in a solid state (dry ice) in filled in such an amount that after evaporation the envelope is not filled to the brim but rather hugs the respective shape of a contact surface (Fig. 3).
An Stelle von fester Kohlensäure können auch andere chemische Elemente oder Verbindungen in festem Zustand, die unter normalen Verhältnissen gasförmig sind, zum gleichen Zweck verwendet werden.Instead of solid carbonic acid, other chemical elements can also be used or compounds in a solid state, which under normal conditions are gaseous are to be used for the same purpose.
Die Arbeitsweise der Hebekörper ist folgende: Nach dem Einbringen eines Hebekörpers mit den festen Kohlensäurestücken in der Hülle in einem Hohlraum eines unter Wasser liegenden Bergungsobjektes und seiner Drehung um 180° geht gemäß der darin herrschenden besonderen Temperatur- und Druckverhältnisse die Kohlensäure in den gasförmigen Zustand über, wobei sie an Volumen stark zunimmt und das in dem Hohlraum befindliche Wasser verdrängt. Da das spezifische Gewicht der gasförmigen Kohlensäure viel geringer ist als das des Wassers, erhält die aufgeblasene Hülle 1 Auftrieb und wird infolgedessen eine Hubkraft gleich dem Gewicht des verdrängten Wassers in Richtung gegen die Wasseroberfläche ausüben. Entsprechend dem Gewicht des aus dem Wasser zu bergenden Objektes ist jeweils eine bestimmte Anzahl von Hebekörpern erforderlich.The working method of the lifting body is as follows: After insertion a lifting body with the solid carbonic acid pieces in the shell in a cavity of a salvage object lying under water and its rotation by 180 ° goes according to the special temperature and pressure conditions prevailing in it, the carbonic acid into the gaseous state, where it increases in volume sharply and that in the Displaced water located in the cavity. Because the specific gravity of the gaseous Carbonic acid is much lower than that of the water, the inflated envelope maintains it 1 buoyancy and will consequently have a lifting force equal to the weight of the displaced Water towards the surface of the water. According to the weight of the object to be rescued from the water is a certain number of lifting bodies necessary.
Die Art, in welcher diese an Ort und Stelle gebracht werden, ist dabei wichtig. Die Hebekörper werden in Pakete zusammengefaßt durch einen Taucher in die Tiefe gebracht. Die Rohrstutzen 2 sind dabei mit dem unteren Ende nach oben gerichtet, so daß das sich stets in geringem Umfang bildende Gas entweichen kann. Sobald die Hebekörper am Einsatzort freigegeben werden, drehen sie sich selbsttätig durch die Wirkung des Gewichtes 4 um 180°.The way in which these are put in place is included important. The lifting bodies are put into packages by a diver in the Brought depth. The pipe socket 2 are directed with the lower end upwards, so that the gas, which is always formed to a small extent, can escape. As soon as the Are released at the place of use, they rotate automatically through the Effect of weight 4 by 180 °.
Die Länge des Rohrstutzens 2 ist der Festigkeit der Hüllenwandung angepaßt. Das Gas kann aus der Hülle 1 entweichen, sobald der Innendruck in der Hülle größer ist als der Wasserdruck in Höhe des unteren Endes des Rohrstutzens 2. Sobald das zu hebende Bergungsobjekt aufsteigt, nimmt der Wasserdruck allmählich ab. Durch das Entweichen des dadurch überschüssig werdenden Gases aus den Hüllen über die Rohrstutzen wird die Gefahr eines Reißens der Hüllen vermieden.The length of the pipe socket 2 is the strength of the shell wall customized. The gas can escape from the envelope 1 as soon as the internal pressure in the Shell is greater than the water pressure at the level of the lower end of the pipe socket 2. As soon as the salvage object to be lifted rises, the water pressure gradually decreases away. Through the escape of the excess gas from the envelopes The risk of tearing the casings is avoided via the pipe socket.
Wenn das zu hebende Bergungsobjekt sich in einer unzugänglichen Tiefe befindet oder in einer Stellung, bei der es unmöglich ist, in sein Inneres einzudringen, können die Hebekörper mittels eines Katapultes in das Innere des Bergungsobjektes geschossen werden. Nachdem sie dann aufgeblasen sind, dichten sie selbst mit ihren Oberflächen das gebildete Leck wieder ab.When the salvage object to be lifted is at an inaccessible depth is located or in a position where it is impossible to penetrate inside, the lifting body can be brought into the interior of the salvage object by means of a catapult to be shot. After they are then inflated, seal with your own Surface the leak that has formed.
In weiterer Anwendung des Erfindungsgegenstandes können die Hebekörper bei geeigneten Abmessungen und zusammen mit entsprechenden Haltemitteln für die Bergung von Minen oder anderen Gegenständen verwendet werden, wenn an diesen ein Hebekörper befestigt werden kann.In a further application of the subject matter of the invention, the lifting body with suitable dimensions and together with appropriate holding means for the Salvage from mines or other objects can be used when at this one Lifting body can be attached.
