Underwater propeller drive with at least one screw propeller, the blade ends of which are one connected with the other by way of a peripheral ring which receives the rotor -excited by a permanent magnet- of an electrical drive motor, the stator of which is accommodated in the fixedly located part, wherein the gap between rotor and stator is flooded, characterized thereby, that the screw propeller with bearing and electrical drive is detachably installed in the end of a transverse channel portion (19), which is pushable as unit into a side wall opening (16) of a ship as far as the abutment (20) in the fixedly installed pipe tunnel (17), wherein the stator (12) is connected by way of a current cable (21) to a terminal box outside the water region.

Description

Die Erfindung befasst sich mit einem Unterwasserpropellerantrieb gemäß den Merkmalen des Oberbegriffs des Hauptanspruches.The invention relates to an underwater propeller drive according to the features of the preamble of the main claim.

Schiffe, von denen eine besondere Manövrierfähigkeit erwartet werden 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, weist 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 maneuverable are often equipped with so-called transverse thrusters. A propeller is arranged in a pipe tunnel lying transversely to the ship's longitudinal axis in the bow area. A drive motor inside the ship drives the propeller via a shaft perpendicular to the transverse channel and a gear nacelle. The gear nacelle, which must accommodate the spur and bevel gears required to transmit the torques, therefore has correspondingly large radial dimensions which greatly narrow the cross section of the tube tunnel. The installation and removal of this transverse jet drive requires docking, or at least an appropriate trimming of the ship. The electrical and also the hydrodynamic efficiency of such drives are relatively poor.

Unterwasserpumpen, z. B. für den Tiefseeeinsatz, arbeiten nach einem ähnlichen Prinzip. In die Förderleitung ist ebenfalls ein Schraubenpropeller eingebaut. Der Antrieb des Propellers kann mit einem Unterwassermotor mit oder ohne Getriebe erfolgen. Mit einem gefluteten Motor sind derartige Pumpen auch für große Tiefen verwendbar. Motor und Getriebe liegen bei dieser Ausführung im Strahlbereich des Propellers. Auch hier wird der Strahlquerschnitt stark verringert. Schließlich ist aus der DE-PS 688 114 ein elektrisch angetriebener Propeller bekannt, bei dem die Flügelenden des Propellerblattes mit einem peripheren Ring verbunden sind, der den elektrisch passiven Teil (Rotor) eines Antriebsmotors aufnimmt. Der elektrisch aktive Teil (Stator) befindet sich in einer den Propeller aufnehmenden Düse.Submersible pumps, e.g. B. for deep sea use, work on a similar principle. A screw propeller is also installed in the delivery line. The propeller can be driven with an underwater motor with or without gear. With a flooded motor, such pumps can also be used for great depths. In this version, the engine and transmission lie in the jet area of the propeller. Here too, the beam cross section is greatly reduced. Finally, from DE-PS 688 114 an electrically driven propeller is known in which the wing ends of the propeller blade are connected to a peripheral ring which receives the electrically passive part (rotor) of a drive motor. The electrically active part (stator) is located in a nozzle receiving the propeller.

Die der Erfindung zugrunde liegende Aufgabe ist darin zu sehen, einen Unterwasserpropellerantrieb zu schaffen, der in Rohrtunnel eiri- und ausbaubar ist, einen maximalen Strömungsquerschnitt und damit einen guten Wirkungsgrad gewährleistet, und bei Nichtbetrieb und ungewollter Anströmung in technisch einfacher Weise abbremsbar ist.The object on which the invention is based is to create an underwater propeller drive which can be built and expanded in tubular tunnels, ensures a maximum flow cross-section and thus good efficiency, and can be braked in a technically simple manner when not in use and when the flow is not wanted.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Hauptanspruches angegebenen Merkmale gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.This object is achieved by the features specified in the characterizing part of the main claim. Further developments of the invention are characterized in the subclaims.

Die besonderen Vorteile des Antriebes nach der Erfindung bestehen darin, daß er kleinvolumig ist, sich leicht austauschen und warten lässt und einen guten Wirkungsgrad besitzt.The particular advantages of the drive according to the invention are that it is small in volume, easy to replace and maintain, and has good efficiency.

  • Figur 1 eine Propellereinheit,

Drive according to claim 1, characterized by the use of the structural unit as an underwater pump in a pump line. The underwater propeller drive according to FIG. 1 is used as a unit in a tube tunnel for transverse jet drives of ships or in delivery lines for deep-sea pumps. The assembly 1 consists of an axially short, cylindrical housing 2, which is open at the end faces. Arm crosses 3, 4 are connected to the housing 2 and accommodate bearings 5, 6 for the shaft 7 of a screw propeller 8. The wing ends of the propeller 8 are connected to a ring 9, in which the rotor 10 with permanent magnets of an electric drive motor is inserted distributed over the circumference. The ring 9 is received by a recess 11 in the housing 2. The stator 12 is also arranged in the housing 2, opposite the rotor 10, distributed over the circumference of the housing 2. A power cable is connected to the stator 12, which lies in a groove 13 of the housing for the purpose of simplified assembly of the unit and is led at the installation location through a tunnel opening to a connection box outside the water 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 Schubwirkung 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 18 kann nun, wie dargestellt, in einer Werkstatt in einem Rohrabschnitt 19 fertig montiert werden. Das Rohr mit der Baueinheit 18 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 21 in einem Steigrohr 22 zu einem Anschlußkasten 23 geführt, der oberhalb der Schiffswesserlinie liegt. Von diesem AnschluBkasten führt wahlweise der Anschluß zur Einspeisestelle oder zu einer KurzschluBschaltung über widerstände. Hierdurch wird bei Nichtbetrieb des Querstrahlantriebes oder der Unterwasserpumpe verhindert, daß durch generatorisches Bremsen des Motors ein unkontrollierter Lauf des Propellers infolge Anströmung stattfindet und dadurch verursschteStörgeräusche entstehen.Figure 2 shows a section of a transverse channel in a ship with a structural unit, here in the form of a double propeller, which rotate in opposite directions in order to better utilize the swirl energy of the one propeller and to increase the thrust effect. 15 denotes the side wall of the ship, which has an opening 16 below the dashed line of the ship's water. A pipe tunnel 17 is laid from this opening 16 to a corresponding opening in the opposite ship's wall. As shown, the propeller unit 18 can now be assembled in a tube section 19 in a workshop. The pipe with the assembly 18 is then transported to the ship and inserted through the side opening 16 into the pipe tunnel 17, up to an annular shoulder 20 in the pipe 17. The pipe section 19 is then firmly connected to the ship wall 15 and that in a groove or Double wall of the pipe section lying power cable 21 in a riser pipe 22 to a junction box 23, which is above the shipwrapper line. From this junction box the connection leads either to the feed point or to a short circuit via resistors. In this way, when the transverse jet drive or the submersible pump is not in operation, the regenerative braking of the engine prevents the propeller from running in an uncontrolled manner as a result of the oncoming flow and the resulting noise. 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 Verlauf des Steigrohres wird dabei jeweils an die Schiffsräumlichkeiten anzupassen sein.Another possibility of assembling the assembly 18 is to insert only this assembly through the side opening 16 into a pipe tunnel and to fasten it in the predetermined position. In this case, the riser pipe for the cable connection can be arranged directly above the assembly. The course of the riser pipe will have to be adapted to the ship's premises. 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 Kabelenschluß am Stator, Steigrohr 33 und AnschluBkasten 34 fertig montiert werden kann. Bei der Montage an Bord ist dann lediglich noch der Anschluß an den Stromerzeuger oder eine KurzschluBschaltung vorzunehmen.Finally, it is possible, as shown in FIG. 3, to provide the assembly 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 by inserting sealing rings 32. The particular advantage of this assembly 25, which is introduced perpendicular to the tunnel axis, is that the assembly can be assembled in the workshop, with cable closure on the stator, riser pipe 33 and connection box 34. When installing on board, the only thing left to do is to connect to the generator or short circuit it.
