Description

Die Erfindung betrifft eine schiffsgestützte Auslaufvorrichtung für ein Verbindungskabel zu einem eigengetriebenen Unterwasserfahrzeug der im Oberbegriff des Anspruchs 1 definierten Gattung.The invention relates to a ship-based Outlet device for a connecting cable to one self-propelled underwater vehicle which in the preamble of Claim 1 defined genus.

Bei einer bekannten Auslaufvorrichtung dieser Art ist auf dem Vordeck des Überwasserschiffes ein Kran mit Seilwinde installiert, der einen mittels der Seilwinde schwenkbaren Kranausleger aufweist, an dessen freiem Ende die Umlenkvorrichtung angeordnet ist. Die Umlenkvorrichtung besteht aus einer im Kranausleger drehbar gehaltenen Kabelführungsrolle und einem an der Kabelführungsrolle angehängten, großen Auslaufgewicht, durch dessen Zentrum das Verbindungskabel hindurchgeführt ist. Im Bereich zwischen Kabelführungsrolle und Auslaufgewicht ist das Verbindungskabel von einer flexiblen Schutzhülle umschlossen. Im Einsatz wird der Kranausleger in Richtung Wasseroberfläche abgeschwenkt, so daß die Kabelführungsrolle mit Abstand vor dem Bug liegt und das Auslaufgewicht ins Wasser eintaucht. Danach wird das an seinem freien Ende mit dem Unterwasserfahrzeug verbundene Verbindungskabel von der Aufwickeltrommel abgewickelt und fiert, gezogen von dem Unterwasserfahrzeug, aus. In a known discharge device of this type is on a crane with winch on the foredeck of the surface ship installed one that swivels by means of the winch Has crane boom, at the free end of the Deflection device is arranged. The deflection device consists of a rotatably held in the crane boom Cable management roller and one on the cable management roller attached, large spout weight, through the center the connecting cable is passed through.

After that it turns on its free end connected to the underwater vehicle Connection cable unwound from the take-up drum and drawn from the underwater vehicle.

Diese bekannte Auslaufvorrichtung hat den Nachteil, daß zum Ablassen und Einholen des schweren Auslaufgewichts ein Kran erforderlich ist und dadurch entsprechend viel Platz auf dem Vordeck vorgehalten werden muß. Das ins Wasser eintauchende Auslaufgewicht bringt durch sein ungünstiges Strömungsverhalten erhebliche Energieverluste mit sich. Darüber hinaus ist diese Auslaufvorrichtung nicht geeignet, in dem für Arbeiten an Deck wesentlich günstigeren, weil geschützter und weniger gefährdet, Heckbereich installiert zu werden, da das Verbindungskabel durch die Schiffsschraube und umgekehrt die Schiffsschraube durch das Verbindungskabel extrem gefährdet ist.This known outlet device has the disadvantage that for Lowering and hauling in the heavy discharge weight using a crane is required and therefore a lot of space must be held up to the foredeck. That into the water immersed discharge weight brings through its unfavorable Flow behavior with considerable energy losses. In addition, this outlet device is not suitable in the much cheaper for work on deck because protected and less vulnerable, rear area installed to be because the connecting cable through the Propeller and vice versa the propeller through the Connection cable is extremely at risk.

Es ist eine Vorrichtung zum Aussetzen und Einholen eines an einem Schleppseil von einem Oberflächenschiff geschleppten Unterwasser-Schleppgerätes, insbesondere Minenräumgerätes bekannt (DE-AS 2 030 162), die das Schleppgerät mit Hilfe eines mit einem Ende an dem Gerät befestigten Schleppseils über einen nach dem Schwerkraftprinzip arbeitenden Schwenkausleger allein durch die Betätigung der Seilwinde aussetzt und aus dem Wasser in Zurrstellung zurückholt. Das Gerät ist dabei mit einem Schleppjoch versehen. Der Ausleger trägt einen Leitkopf aus zwei maulartig ausgebildeten Kopfflächen. Beim Einholen zieht die Seilwinde mit dem Schleppseil das Schleppgerät über eine Seilscheibe und Leitscheibe sowie über den Leitkopf des Auslegers bis zu dessen Endlage ein. Zum Aussetzen des Schleppgerätes wird durch Fieren des Schleppseils der Ausleger nach unten geschwenkt, bis der Leitkopf in das Wasser eintaucht. Nimmt das Oberflächenschiff Fahrt auf, so zieht der Schleppkörper das Schleppseil über die Seilscheibe von der freigegebenen Seilwinde ab. It is a device for suspending and catching up on a tow towed by a surface ship Underwater towing device, in particular mine clearing device known (DE-AS 2 030 162), which the towing device with the help one with one end attached to the device about one working on the principle of gravity Swivel boom only by operating the winch suspends and retrieves from the water in the lashing position. The The device is equipped with a yoke. The Boom carries a lead head made of two mouths trained head areas. When pulling the pulls Winch with the tow rope the towing device over a Rope pulley and guide pulley as well as over the guide head of the Boom up to its end position. To suspend the The towing device is by pulling the tow rope The boom is pivoted downwards until the guide head is in the Water immersed. If the surface ship picks up speed, so the tow body pulls the tow rope over the Pulley from the approved winch.

Der Erfindung liegt die Aufgabe zugrunde, eine Auslaufvorrichtung der eingangs genannten Art zu schaffen, die ein Aus- und Einbringen des Verbindungskabels vom Heckbereich aus ohne Kollisionsgefahr mit der Schiffsschraube ermöglicht, und darüber hinaus leichtgewichtig ist, so daß keine zusätzlichen, schiffsseitigen, motorischen Hebewerkzeuge, die -zusätzlichen Bauraum erfordern, notwendig sind.The invention has for its object a To create outlet device of the type mentioned at the outset, which a removal and insertion of the connecting cable from Rear area out with no risk of collision with the Allows propeller, and beyond is lightweight, so that no additional, ship-side, motorized lifting tools, the -additional Require space, are necessary.

Die Aufgabe ist erfindungsgemäß durch die Merkmale im Anspruch 1 gelöst.The object is according to the features in Claim 1 solved.

Die erfindungsgemäße Auslaufvorrichtung hat den Vorteil, daß durch das steife Schutzrohr, dessen Rohrmündung unterhalb der Schiffsschraube liegt, sichergestellt ist, daß das Verbindungskabel zu keinem Zeitpunkt seines Fierens, seines Einholens oder seines Verbleibs im Wasser mit der Schiffsschraube in Berührung kommen kann. Beim Ausbringen des Verbindungskabels kann das Schutzrohr in der Horizontalen arretiert werden und hält dadurch das Verbindungskabel weit vom Schiffsheck und damit von der Schiffsschraube ab. Nehmen Schiff und Unterwasserfahrzeug Fahrt auf, taucht das Schutzrohr ins Wasser ein und nimmt eine der Strömung angepaßte Stellung ein. Durch sein strömungsgünstiges Profil treten dabei nur geringe Energieverluste auf. Gelangt das Schutzrohr durch Aufstoppen des Schiffs, durch starke Beschleunigung des Unterwasserfahrzeugs oder durch starke Anströmung von hinten in die vertikale Stellung, so wird, z.B. durch einen Anschlag, eine Weiterbewegung des Schutzrohrs in Richtung Schiffsschraube blockiert.The outlet device according to the invention has the advantage that through the rigid protective pipe, the pipe mouth below the propeller, it is ensured that the connecting cable at no time its Fishing, catching up or staying in the water can come into contact with the propeller. At the The protective tube can be brought out in the Horizontal are locked and thereby holds that Connection cable far from the ship's stern and thus from the Propeller. Take ship and underwater vehicle Drive up, immerse the protective tube in the water and take a position adapted to the flow. Be through aerodynamic profile occur only slight Energy losses. Get through the protective tube Stopping the ship by strongly accelerating the Underwater vehicle or by strong inflow of rear to the vertical position, e.g. through a Stop, a further movement of the protective tube in the direction Ship propeller blocked.

Zweckmäßige Ausführungsformen der erfindungsgemäßen Auslaufvorrichtung mit vorteilhaften Weiterbildungen und Ausgestaltungen der Erfindung ergeben sich aus den weiteren Ansprüchen.
Gemäß einer vorteilhaften Ausführungsform der Erfindung ist das freie Rohrende des Schutzrohrs bogenförmig so krümmbar ausgebildet, daß die Achse der Rohrmündung etwa rechtwinklig zur Rohrachse verläuft und die Rohrmündung in Richtung Schiffsschraube weist. Bevorzugt wird dabei dieser endseitige Krümmungsbereich durch gelenkig miteinander verbundene Rohrsegmente realisiert, die in Längsrichtung des Schutzrohrs aneinandergereiht sind. Durch diese konstruktiven Maßnahmen wird nahe dem Rohraustritt des Verbindungskabels ein Führungsradius für das Verbindungskabel erzeugt, der ein Knicken und Beschädigen des Kabels an seiner Austrittsstelle aus dem Schutzrohr zuverlässig verhindert.
Expedient embodiments of the outlet device according to the invention with advantageous developments and refinements of the invention result from the further claims.
According to an advantageous embodiment of the invention, the free tube end of the protective tube is curved so that the axis of the tube mouth is approximately perpendicular to the tube axis and the tube mouth points in the direction of the propeller. This region of curvature at the end is preferably realized by pipe segments which are connected to one another in an articulated manner and are lined up in the longitudinal direction of the protective tube. These design measures create a guide radius for the connecting cable near the pipe outlet of the connecting cable, which reliably prevents the cable from kinking and being damaged at its point of exit from the protective tube.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist das Schutzrohr um seine Längsachse zumindest beschränkt drehbar ausgebildet. Dadurch ist das Schutzrohr in der Lage, bei seitlicher Anströmung durch Drehung um seine Längsachse sich in die Strömung zu legen und einen nur kleinen Widerstand im Wasser zu erzeugen.According to an advantageous embodiment of the invention the protective tube is at least limited about its longitudinal axis rotatable. As a result, the protective tube is in the Position, with lateral flow by rotation around its Longitudinal axis to lie in the flow and only one to create little resistance in the water.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist das Schutzrohr seitlich beschränkt auslenkbar ausgebildet. Durch diese seitliche Auslenkbarkeit des Schutzrohrs, was vorzugsweise durch eine elastische Festlegung des der Umlenkvorrichtung zugekehrten Rohrendes am Schiffsdeck realisiert wird, werden auf das Schutzrohr durch Rollen des Schiffes oder durch Anströmung wirkende, seitliche Kräfte ausgeglichen.According to an advantageous embodiment of the invention the protective tube is designed to be deflectable to a limited extent. Because of this lateral deflection of the protective tube, what preferably by an elastic definition of the Deflection device facing the pipe end on the ship deck is realized on the protective tube by rolling the Vessel or side forces caused by the flow balanced.

Gemäß einer vorteilhaften Ausführungsform der Erfindung wird das Schutzrohr an seinem der Umlenkvorrichtung zugekehrten Rohrende deckseitig schnell demontierbar festgelegt. Dadurch besteht die Möglichkeit, bei vorübergehendem Nichtgebrauch das Schutzrohr zusammen mit dem darin geführten Kabelabschnitt der Länge nach auf dem Schiffsdeck zu lagern.According to an advantageous embodiment of the invention the protective tube is at its the deflection device the facing end of the pipe can be quickly dismantled established. This makes it possible to temporarily not using the protective tube together with the cable section guided in it lengthways on the Store ship deck.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist das Schutzrohr aus zwei formschlüssig fügbaren Rohrschalen zusammengesetzt, die fest miteinander, z.B. durch Clipsen oder Schrauben, verbunden sind. Diese konstruktive Ausbildung des Schutzrohrs gibt die Möglichkeit, z.B. beim Austausch des Verbindungskabels das Kabel aus dem Schutzrohr herauszunehmen, ohne die endseitig vorhandenen Steckverbinder zum Anschluß des Kabels an das Unterwasserfahrzeug und an die schiffsseitige Versorgungseinheit von dem Versorgungskabel trennen zu müssen.According to a preferred embodiment of the invention the protective tube made of two form-fitting tube shells composed, which are firmly together, e.g. by clips or screws. This constructive Forming the protective tube gives the possibility, e.g. at the Replacing the connecting cable the cable from the Take out the protective tube without the existing ones Connector for connecting the cable to the Underwater vehicle and to the ship's side Disconnect the supply unit from the supply cable have to.

Zur Festlegung des Schutzrohrs 20 in seiner Horizontalstellung sind schiffsseitig besondere Verriegelungsmaßnahmen getroffen.The underwater vehicle 11 is moved from Aft deck 101 of the surface ship 10, which turns out to be Working platform has proven to be the most appropriate. Either the insertion of the underwater vehicle 11 into the water as also the lifting of the underwater vehicle 11 from the Water takes place by means of one on the aft deck 101 arranged lifting crane or davits 15, as shown in Fig.2 see is. The connecting cable is already at the time of deployment 14 via detachable connectors with the underwater vehicle 11 connected, and the connecting cable 14 is on one the aft deck 101 installed cable drum 16 (Fig. 2nd and 3) wound up. When lowering and getting the Underwater vehicle 11 by means of the davit 15 as well during the mission of the underwater vehicle 11 in the water the connecting cable 14 is arranged at the rear Outlet device 17 out, which is designed so that at no time the connecting cable 14 near the Propeller 18 can get so that mutual Damage to propeller 18 and connecting cable 14 are reliably excluded. The Outlet device 17 in addition to the motor-driven Cable drum 16 for fisting and hauling the Connecting cable 14 still a deflection device 19 for Run the connecting cable 14. As from FIGS. 2 and 3 can be seen, the deflection device 19 on the Rear edge of the aft deck 101 arranged. Immediately the deflection device 19 closes a protective tube 20 at that with its pipe start 201 on the deflection device 19 is attached, and the pipe mouth 202 at least in vertical alignment of the longitudinal axis of the protective tube 20 is below the propeller 18 (Fig.2). How else is explained below, the protective tube 20 is in one vertical plane aligned parallel to the ship's longitudinal axis swiveling, the swiveling movement over the vertical is blocked in the direction of the propeller 18. This position of the protective tube 20 is shown in Fig.2. Other swivel positions of the Protective tube 20 indicated, with 21 the normal position of the protective tube 20 when the surface ship 10 and at 22 the horizontal swivel position of the protective tube 20 characterized when deploying the underwater vehicle 11 is. To fix the protective tube 20 in its Horizontal positions are special on the ship side Interlocking measures taken.

Die Umlenkvorrichtung 19 ist in Fig.4 perspektivisch und in Fig.5 in Frontansicht jeweils vergrößert dargestellt. Sie weist einen Lagerbock 23 und ein im Lagerbock 23 schwenkbares Kabelführungsglied 24 auf, an dessen Kabelauslaufseite das Schutzrohr 20 angesetzt ist. Der Lagerbock 23 ist mittels zweier Gummi-Metall-Lager 25 elastisch auf dem Achterdeck 101 befestigt. Die Umlenkvorrichtung 19 weist zwei im Abstand voneinander, parallel angeordnete Führungsplatten 26 auf, die durch Distanzstege fest miteinander verbunden sind. Zwischen den Führungsplatten 26 sind mehrere Führungs- oder Umlenkrollen 36 (Fig.5) angeordnet, die den zwischen den Führungsplatten 26 einliegenden Kabelabschnitt des Verbindungskabels 14 abstützen und auf einem Kreisbogen um 90° umlenken. An der Kabelauslaufseite der Umlenkvorrichtung 19 ist zwischen den beiden Führungsplatten 26 der Rohranfang 201 des Schutzrohrs 20 festgelegt. Die beiden Führungsplatten 26 sitzen drehbeweglich auf einem Steckbolzen 27, der im Lagerbock 23 lösbar gehalten ist, so daß nach Herausziehen des Steckbolzen 27 das mit dem Führungsplattenpaar 26 verbundene Schutzrohr 20 aus dem Lagerbock 23 herausgenommen werden und zusammen mit dem in dem Schutzrohr 20 einliegenden Kabelabschnitt der Länge nach auf dem Achterdeck 101 gelagert werden kann. Wie in Fig.4 weiter nicht dargestellt ist, ist am Lagerbock 23 noch ein Arretierglied vorgesehen, das in das Führungsplattenpaar 26 lösbar einrastet, wenn das Schutzrohr 20 in seine in Fig.2 strichpunktiert angedeutete Horizontallage 22 hochgeschwenkt worden ist. Wie bereits erwähnt, wird diese Horizontallage 22 des Schutzrohrs 20 während des Ausbringvorgangs des Unterwasserfahrzeugs 11 und des Verbindungskabels 14 eingestellt. Durch die elastische Lagerung des Lagerbocks 23 auf dem Achterdeck 103 (Gummi-Metall-Lager 25) ist das Schutzrohr 20 beschränkt seitlich auslenkbar, wie dies in Fig.5 durch die beiden strichpunktierten Linien symbolisiert ist. Dadurch werden seitliche Kräfte auf das Schutzrohr 20 ausgeglichen, die z.B. infolge von Rollen des Schiffes oder durch Anströmung am Schutzrohr 20 angreifen. Wie nicht weiter dargestellt ist, ist das Schutzrohr 20 um seine Längsachse drehbar ausgebildet, was beispielsweise durch eine entsprechende Drehlagerung des Rohranfangs 201 im Kabelführungsglied 24 realisiert werden kann. Dies ist in sofern von Vorteil, als bei seitlicher Anströmung des im Wasser befindlichen Teils des Schutzrohrs 20 das'Schutzrohr 20 in der Lage ist, sich durch Drehen um seine Längsachse in die Strömung zu legen und damit einen nur geringen Widerstand im Wasser zu erzeugen.The deflection device 19 is perspective in FIG. 4 and in FIG Fig. 5 shown enlarged in front view. she has a bearing block 23 and one in the bearing block 23 pivotable cable guide member 24, on the The protective tube 20 is attached to the cable outlet side. The Bearing block 23 is by means of two rubber-metal bearings 25 fastened elastically on the quarterdeck 101. The Deflection device 19 has two spaced apart, parallel arranged guide plates 26 through Spacers are firmly connected. Between Guide plates 26 are a plurality of guide or deflection rollers 36 (Fig.5) arranged between the guide plates 26 inserted cable section of the connecting cable 14 support and deflect on a circular arc by 90 °. At the Cable outlet side of the deflection device 19 is between the two guide plates 26 of the pipe start 201 of the Protection tube 20 set. The two guide plates 26 sit rotatably on a socket pin 27, which in Bearing bracket 23 is releasably held so that after pulling out of the plug pin 27 with the pair of guide plates 26 connected protective tube 20 from the bearing block 23 be taken out and together with the in the Protective tube 20 lying length of cable can be stored on the quarterdeck 101. As in Fig.4 is not shown, is still on the bracket 23 Locking member provided that in the pair of guide plates 26th releasably engages when the protective tube 20 in its in Fig.2 dash-dotted horizontal position 22 has been swung up. As mentioned earlier, this is Horizontal position 22 of the protective tube 20 during the Deployment of the underwater vehicle 11 and Connection cable 14 set. Due to the elastic Storage of the bearing block 23 on the aft deck 103 (rubber-metal bearing 25) the protective tube 20 is limited laterally deflectable, as shown in Figure 5 by the two dash-dotted lines is symbolized. This will lateral forces balanced on the protective tube 20, the e.g. due to rolling of the ship or by inflow attack the protective tube 20. As not shown further is, the protective tube 20 is rotatable about its longitudinal axis trained what, for example, by a corresponding Rotary bearing of the pipe start 201 in the cable guide member 24 can be realized. This is advantageous in so far as when the part in the water flows against the side of the protective tube 20, the protective tube 20 is able to itself by rotating it around its longitudinal axis in the flow and thus only a slight resistance in the water produce.

Das Schutzrohr 20, das in Fig.6 vergrößert in seinem Endbereich und in Fig.7 im Querschnitt dargestellt ist, ist aus zwei formschlüssig fügbaren Rohrschalen 28,29 zusammengesetzt, die fest miteinander verbunden sind. Die Verbindung erfolgt durch eine Reihe von Schraubverbindungen, von denen in Fig.7 eine Schraube 30 dargestellt und eine Schraubverbindung 31 durch Strichpunktierung angedeutet ist. Der in dem Schutzrohr 20 ausgebildete, hohlzylindrische Führungsschacht für das Verbindungskabel 14 ist mit 32 bezeichnet. Durch die beiden formschlüssig zusammengefügten Rohrschalen 28,29 erhält das Schutzrohr 20 eine strömungsgünstig geformte Außenkontur, die etwa Tropfenform aufweist und einen wesentlich kleineren Strömungswiderstand besitzt, als das zwar durchmesserkleinere aber kreisrunde Verbindungskabel 14. Die Anströmungsrichtung des im Querschnitt tropfenförmigen Schutzrohrs 20 bei Fahrt von Oberflächenschiff 10 und Unterwasserfahrzeug 11 durch das Wasser ist in Fig.6 und 7 durch Pfeil 33 symbolisiert.The protective tube 20, which is enlarged in Fig.6 End region and is shown in Figure 7 in cross section from two form-fitting pipe shells 28, 29 composed, which are firmly connected. The Connection is through a series of Screw connections, of which a screw 30 in FIG. 7 shown and a screw connection 31 Dash-dotted lines are indicated. The in the protective tube 20th trained, hollow cylindrical guide shaft for the Connection cable 14 is designated 32. Through the two the form-fitting assembled tubular shells 28, 29 receive this Protection tube 20 an aerodynamically shaped outer contour, which is roughly teardrop-shaped and essential has smaller flow resistance than that smaller diameter but circular connecting cables 14. The flow direction of the drop-shaped in cross section Protection tube 20 when driving from surface ship 10 and Underwater vehicle 11 through the water is in Figures 6 and 7 symbolized by arrow 33.

Um ein Abknicken oder Beschädigen des Verbindungskabels 14 beim Austritt aus dem Schutzrohr 20 zuverlässig auszuschließen, ist das freie Rohrende des Schutzrohrs 20 bogenförmig krümmbar, wie dies in Fig.2 und 6 dargestellt ist, wodurch die Achse der Rohrmündung 202 bis etwa rechtwinklig zur Rohrlängsachse verlaufen kann und die Rohrmündung 202 in Richtung Schiffsschraube 18 weist. Diese Krümmungsmöglichkeit des Schutzrohrs 20 wird dadurch erreicht, daß der endseitige Krümmungsbereich aus Rohrsegmenten 34 (Fig.6) zusammengesetzt ist, die nahe ihres vorderen Anströmendes miteinander gelenkig verbunden sind. Die Gelenkverbindung zwischen den Rohrsegmenten 34 ist in Fig.6 durch die Linie 35 angedeutet. Jedes Rohrsegment 34 weist die gleiche Außenkontur wie der übrige Bereich des Schutzrohrs 20 auf und hat eine Querschnittsfläche, die im wesentlichen mit der in Fig.7 dargestellten Querschnittsfläche des starren Rohrbereichs übereinstimmt.To kink or damage the connecting cable 14 reliably when exiting the protective tube 20 exclude the free tube end of the protective tube 20 arcuately curved, as shown in Fig. 2 and 6 is, whereby the axis of the pipe mouth 202 to about can run perpendicular to the pipe longitudinal axis and the Pipe mouth 202 points in the direction of propeller 18. This Possibility of curvature of the protective tube 20 is thereby achieved that the end curvature area Pipe segments 34 (Fig.6) is composed, the near their front inflow end articulated together are. The articulation between the pipe segments 34 is indicated in Figure 6 by line 35. each Pipe segment 34 has the same outer contour as the rest Area of the protective tube 20 and has one Cross-sectional area which is essentially the same as that in Fig.7 shown cross-sectional area of the rigid pipe area matches.
