"Unteruasserpropellerantrieb""Underwater propeller drive"
Die Erfindung befasst sich mit einem Untertuasaerpropellerantrieb gemäß den Merkmalen des Oberbegriffs des Hauptanspruches.The invention is concerned with an underwater propeller drive according to the features of the preamble of the main claim.
Schiffe, von denen eine besondere Manövrierfähigkeit erwartet uierden muß, werden häufig mit sogenannten Querstrahlrudern ausgestattet. In einem quer zur Schiffslängsachse im Bugbereich liegende Rohrtunnel ist ein Propeller angeordnet. Ein Antriebsmotor im Inneren des Schiffes treibt über eine senkrecht zum Querkanal liegende Welle und eine Getriebegondel den Propeller an. Die Getriebegondel, die die zur Übertragung der Drehmomente erforderlichen Stirn- und Kegelräder aufnehmen muß, meist daher entsprechend große radiale Abmessungen auf, die den Querschnitt des Rohrtunnels stark verengen. Der Ein- und Ausbau dieses Querstrahlantriebes erfordert ein Eindocken, zumindest aber ein entsprechendes Trimmen des Schiffes. Der elektrische und auch der hydrodynamische Wirkungsgrad solcher Antriebe sind verhältnismässig schlecht.Ships that are expected to be particularly manoeuvrable uierden must, are often with so-called transverse thrusters fitted. One at right angles to the ship's longitudinal axis in the bow area A propeller is arranged in the lying pipe tunnel. A drive motor inside the ship drives over a perpendicular to the Transverse channel lying shaft and a gear nacelle to the propeller. The transmission pod, which is used to transmit the torque required spur and bevel gears, usually therefore correspondingly large radial dimensions that the cross-section narrow the pipe tunnel. The installation and removal of this transverse thruster requires docking, at least but a corresponding trimming of the ship. The electric one and also the hydrodynamic efficiency of such drives relatively bad.

Der Unterwasserpropellerantrieb gemäß Figur 1 ist für sich als Baueinheit in Rohrtunnel für Querstrahlantriebe von Schiffen oder in Förderleitungen für Tiefseepumpen einsetzbar. Die Baueinheit 1 besteht aus einem axial kurzen, zylindrischen Gehäuse 2, das an den Stirnseiten offen ist. Mit dem Gehäuse 2 sind Armkreuze 3, k verbunden, die Lager 5, 6 für die Idelle 7 eines Schraubenpropellers β aufnehmen. Die Flügelenden des Propellers θ sind mit einem Ring 9 verbunden, in welchem über den Umfang verteilt der Rotor 1G mit Permanentmagneten eines elektrischen Antriebsmotor eingesetzt ist. Der Ring 9 uiird von einer Aussparung 11 im Gehäuse 2 aufgenommen. In dem Gehäuse 2 ist, dem Rotor 1G gegenüber, ebenfalls über den Umfang de-s Gehäuses 2 verteilt, der Stator 12 angeordnet. An den Stator 12 ist ein Stromkabel angeschlossen, das zwecks vereinfachter Montage der Baueinheit in einer Nut 13 des Gehäuses liegt und am Einbauort durch eine Tunnelöffnung zu einem Anschlußkasten außerhalb des Uaaserberelchs geführt uiird.The underwater propeller drive according to FIG. 1 can be used as a structural unit in pipe tunnels for transverse thrusters for ships or in delivery lines for deep-sea pumps. The structural unit 1 consists of an axially short, cylindrical housing 2 which is open at the end faces. With the housing 2, spiders 3, k are connected, which accommodate bearings 5, 6 for the idle 7 of a screw propeller β. The blade ends of the propeller θ are connected to a ring 9 in which the rotor 1G with permanent magnets of an electric drive motor is inserted, distributed over the circumference. The ring 9 is received in a recess 11 in the housing 2. The stator 12 is arranged in the housing 2, opposite the rotor 1G, also distributed over the circumference of the housing 2. A power cable is connected to the stator 12 and, for the purpose of simplified assembly of the structural unit, lies in a groove 13 of the housing and at the installation site through a tunnel opening to a junction box outside the outside area.
Figur 2 zeigt einen Ausschnitt aus einem Querkanal in einem Schiff mit einer Baueinheit, hier in Form eines Doppelpropellers, die gegenläufig drehen, um die Drallenergie des einen Propellers besser ausnutzen zu können und die Schubuiirkung zu erhöhen. Mit 15 ist die eine Seitenwand des Schiffes bezeichnet, die eine Öffnung 16 unterhalb der gestrichelt dargestellten Schiffswasserlinie aufweist. Von dieser Öffnung 16 zu einer entsprechenden Öffnung in ,der gegenüberliegenden Schiffswand ist ein Rohrtunnel 17 verlegt. Die Propellereinheit 1Θ kann nun, wie dargestellt, in einer Werkstatt in einem Rahrabschnitt 19 fertig montiert werden. Das Rohr mit der Baueinheit 1Θ wird danach zum Schiff transportiert und durch die Seitenöffnung 16 in den Rohrtunnel 17 eingeschoben, bis zu einem ringförmigen Absatz 20 im Rohr 17. Der Rohrabschnitt 19 wird dann fest mit der Schiffswand 15 verbunden und das in einer Nut oder einer Doppelwandung des Rohrabschnittes liegende Stromkabel in einem Steigrohr 22 zu einem Anschlußkasten 23 geführt, der oberhalb der Schiffswasserlinie liegt. Won diesem AnschlußkastenFigure 2 shows a section of a transverse channel in one Ship with one structural unit, here in the form of a double propeller, which rotate in opposite directions in order to be able to better utilize the swirl energy of one propeller and to increase the thrust raise. With 15 one side wall of the ship is referred to, which has an opening 16 below that shown in dashed lines Has ship's waterline. From this opening 16 to one corresponding opening in, the opposite ship wall a pipe tunnel 17 is laid. The propeller unit 1Θ can now, as shown, in a workshop in a Rahrabschnitt 19 can be fully assembled. The tube with the assembly 1Θ is then transported to the ship and pushed through the side opening 16 into the pipe tunnel 17, up to an annular one Paragraph 20 in the pipe 17. The pipe section 19 is then solid connected to the ship wall 15 and the power cable lying in a groove or a double wall of the pipe section guided in a riser pipe 22 to a junction box 23 which is above the ship's waterline.

führt wahlweise der Anschluß zur Einspeisestelle ader zu einer Kurzschlußschaltung Ober Widerstände. Hierdurch wird bei IMichtbetrieb des Querstrahlantriebes oder der Unterwasserpumpe verhindert, daß durch generatorisches Bremsen des Motors ein unkontrollierter Lauf des Propellers infolge Anströmung stattfindet und dadurch verursachte Störgeräusche entstehen.optionally the connection to the feed point leads to a Short circuit above resistors. This means that when I is not in operation the transverse thruster or the underwater pump prevents that by regenerative braking of the motor an uncontrolled run of the propeller takes place due to the flow and the resulting noises arise.
Eine andere Möglichkeit der Montage der Baueinheit 18 besteht darin, nur diese Baueinheit durch die Seitenöffnung 16 in einen Rohrtunnel einzuschieben und in der vorbestimmten Position zu befestigen. Das Steigrohr für den Kabelanschluß kann in diesem Falle direkt über der Baueinheit angeordnet sein. Der l/erlauf des Steigrohres uiird dabei jeweils an die Schiffsräumlichkeiten anzupassen sein.There is another possibility of assembling the structural unit 18 therein, only this unit through the side opening 16 in one Insert the pipe tunnel and secure it in the predetermined position. The riser pipe for the cable connection can be in this Trap can be arranged directly above the structural unit. The l / erlauf of the riser pipe is connected to the ship's premises to be adapted.
Schließlich ist es möglich, wie Figur 3 zeigt, die Baueinheit 25 mit Flanschen 26, 27 zu versehen und mit Flanschen 28, 29 an den Enden der fest verlegten Querkanalabschnitte 30, 31 unter Einfügung von Dichtungsringen 32 fest zu verbinden. Bei dieser senkrecht zur Tunnelachse eingeführten Baueinheit 25 ist der besondere Vorteil festzustellen, daß die Baueinheit in der Werkstatt mit Kabelanschluß am Stator, Steigrohr 33 und Anschlußkasten 3h fertig montiert werden kann. Bei der Montage an Bord ist dann lediglich noch der Anschluß an den Stromerzeuger oder eine Kurzschlußachaltung vorzunehmen.Finally, as FIG. 3 shows, it is possible to provide the structural unit 25 with flanges 26, 27 and to firmly connect it with flanges 28, 29 at the ends of the fixed transverse channel sections 30, 31 with the insertion of sealing rings 32. With this unit 25 introduced perpendicular to the tunnel axis, the particular advantage is that the unit can be fully assembled in the workshop with a cable connection on the stator, riser pipe 33 and junction box 3h. When installing on board, all you have to do is connect to the generator or short-circuit.
