Description
Die Erfindung betrifft eine Belüftungsvorrichtung für ein getaucht havariertes Unterseeboot mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.The invention relates to a ventilation device for a submerged submarine submerged with the features specified in the preamble of claim 1.
Es sind Unterseeboote bekannt, die an ihrem Druckkörper an einem von außerhalb des Unterseeboots zugänglichen Bereich einen Be- und Entlüftanschluss aufweisen. Bei einer Havarie des getauchten Unterseebootes ist es möglich, an diese Anschlüsse eine Versorgungs- und Entlüftungsleitung anzuschließen und das Unterseeboot von einem Überwasserschiff aus über die Versorgungsleitung mit Luft zu versorgen bzw. zu durchlüften.There are known submarines, which have on their pressure hull at an area accessible from outside the submarine a ventilation and venting port. In case of an accident of submerged submarine, it is possible to connect to these connections a supply and vent line and to supply the submarine from a surface vessel via the supply line with air or to ventilate.
Hierzu weist ein aus
Eine ähnliche Konstruktion ist aus der
Insbesondere dann, wenn ein Unterseeboot in verhältnismäßig großer Tiefe havariert ist, besteht allerdings bei der oben beschriebenen Belüftung des Unterseeboots ein Problem. Die an den Belüftungsanschluss anzuschließende Entlüftungsleitung wird typischerweise mit dem Überwasserschiff zum Havarieort des Unterseeboots gebracht und muss dementsprechend auf diesem gelagert werden. Insofern bietet sich als Versorgungsleitung ein flexibler Schlauch an, der aufgerollt bzw. zusammengefaltet Platz sparend auf dem Schiff gelagert werden kann. Dem steht jedoch als Nachteil entgegen, dass dieser für die Entlüftung zuständige Schlauch bei der Belüftung eines havarierten Unterseeboots, in dessen Inneren maximal 1 bis 3 bar herrschen können, in größerer Wassertiefe an seiner Außenseite dem vergleichsweise hohen Wasserdruck ausgesetzt ist und entsprechend druckfest ausgebildet sein muss, was aber bei einem Schlauch mit einem benötigten Nenndurchmesser von etwa 50 cm kaum möglich ist. Infolgedessen ist es in einer solchen Situation erforderlich, dass Unterseeboot mit einem Druck zu belüften, der größer als der von außen auf den Schlauch wirkende Wasserdruck sein muss. Sofern sich an Bord des Unterseeboots aber noch lebende Personen aufhalten, ist zu berücksichtigen, dass der Druck der Belüftungsluft eine gewisse Obergrenze nicht überschreiten darf, da es ansonsten zu einer Gesundheitsgefährdung der in dem Unterseeboot befindlichen Personen kommen kann. Daher kann es sein, dass ein Schlauch nicht zur Belüftung eines Unterseeboots verwendet werden kann. Alternativ ist es möglich, zur Belüftung des Unterseeboots an dessen Belüftungsanschluss eine druckfeste Rohrleitung anzuschließen. Mit dieser Rohrleitung ist es aufgrund dessen gegenüber Schläuchen größerer Druckfestigkeit möglich, das Unterseeboot mit einem geringeren Druck zu belüften, der die an Bord befindlichen Personen nicht gefährdet. Allerdings ist eine solche Rohrleitung aus Platzgründen kaum auf einem Schiff zu lagern und weist zudem den Nachteil auf, dass sie keine Bewegungen des Schiffs an der Wasseroberfläche, beispielsweise aufgrund von Wellenbewegungen, ausgleichen kann.In particular, when a submarine has been damaged in a relatively large depth, however, there is a problem with the aeration of the submarine described above. The vent line to be connected to the vent port typically becomes with the surface ship brought to the accident location of the submarine and must therefore be stored on this. In this respect, offers itself as a supply line to a flexible hose, which can be rolled up or stored folded to save space on the ship. However, this is contrary to the disadvantage that this responsible for the vent hose in the ventilation of a damaged submarine, inside which a maximum of 1 to 3 bar can prevail, in greater depth on its outside the relatively high water pressure is exposed and must be designed to be pressure resistant, but this is hardly possible in a hose with a required nominal diameter of about 50 cm. As a result, in such a situation, it is necessary to aerate the submarine at a pressure greater than the external water pressure on the hose. However, if there are still living persons aboard the submarine, it must be borne in mind that the pressure of the ventilation air must not exceed a certain upper limit, since otherwise there may be a risk to the health of the persons in the submarine. Therefore, a hose may not be used to ventilate a submarine. Alternatively, it is possible to connect a pressure-resistant pipe to ventilate the submarine at its ventilation connection. With this pipeline, it is possible because of hoses greater compressive strength to aerate the submarine with a lower pressure, which does not endanger the people on board. However, for reasons of space, such a pipeline is scarcely to be stored on a ship and moreover has the disadvantage that it can not compensate for movements of the ship on the water surface, for example due to wave movements.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine Belüftungsvorrichtung für ein getaucht havariertes Unterseeboot zu schaffen, die es ermöglicht, zur Belüftung des Unterseebootes eine flexible Schlauchleitung zu verwenden, ohne aber bei Einsatz dieser Schlauchleitung an Bord des Unterseebootes befindliche Personen zu gefährden.Against this background, the invention has for its object to provide a ventilation device for a submerged submarine submerged, which makes it possible to use a flexible hose line for ventilation of the submarine, but without jeopardizing persons using this hose on board the submarine.
Gelöst wird diese Aufgabe durch eine Belüftungsvorrichtung mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen dieser Belüftungsvorrichtung ergeben sich aus den Unteransprüchen, der nachfolgenden Beschreibung sowie der Zeichnung. Hierbei können gemäß der Erfindung in den Unteransprüchen und der Beschreibung angegebene Merkmale jeweils für sich aber auch in Kombination die erfindungsgemäße Lösung gemäß Anspruch 1 weiter ausgestalten.This object is achieved by a ventilation device having the features specified in claim 1. Advantageous developments of this ventilation device will become apparent from the dependent claims, the following description and the drawings. Here you can according to the invention in the subclaims and the description given characteristics in each case in itself but also in combination, the solution according to the invention according to claim 1 further.
Die erfindungsgemäße Belüftungsvorrichtung für ein getaucht havariertes Unterseeboot ist an einen Belüftungsanschluss eines Unterseebootes anschließbar und mit einem Anschluss für eine an die Wasseroberfläche führende Versorgungsleitung ausgestattet. Gemäß der Erfindung ist in einem Leitungspfad von dem Anschluss für die Versorgungsleitung zu dem Belüftungsanschluss des Unterseebootes ein Druckminderer angeordnet.The ventilation device according to the invention for a submerged boat that has been submerged is connectable to a ventilation connection of a submarine and equipped with a connection for a supply line leading to the water surface. According to the invention, a pressure reducer is arranged in a line path from the connection for the supply line to the ventilation connection of the submarine.
Demzufolge ist es mit der erfindungsgemäßen Belüftungsvorrichtung möglich, Druckluft von einem Überwasserschiff zu der an einem Lüftungsanschluss des Unterseebootes beispielsweise mittels einer Schnellkupplung angeschlossenen Belüftungsvorrichtung zu leiten und den Luftdruck in der Belüftungsvorrichtung mit dem Druckminderer auf ein Druckniveau zu entspannen, das die in dem Unterseeboot befindlichen Personen nicht gefährdet. Als Versorgungsleitung von dem Überwasserrettungsschiff zu der Belüftungsvorrichtung kann ein flexibler Schlauch verwendet werden, da die Luft mit einem so großen Druck zu der Belüftungsvorrichtung geleitet werden kann, dass sie stützend innerhalb des Schlauches gegen den auf die Außenseite des Schlauches wirkenden Wasserdruck wirkt.Accordingly, it is possible with the ventilation device according to the invention to direct compressed air from a surface vessel to the ventilation device of the submarine, for example by means of a quick coupling connected ventilation device and to relax the air pressure in the ventilation device with the pressure reducer to a pressure level, which is located in the submarine people not endangered. A flexible hose can be used as the supply line from the overwater rescue vessel to the aeration device since the air can be directed to the aerator with sufficient pressure to support the water pressure acting on the outside of the hose supportively within the hose.
Vorteilhaft kann die Belüftungsvorrichtung auch an einen Entlüftungsanschluss des Unterseeboots anschließbar sein und so auch zur Entlüftung des Unterseebootes ausgebildet sein. Das heißt, neben einem Anschluss an den unterseebootseitigen Belüftungsanschluss kann die Belüftungsvorrichtung einen weiteren Anschluss aufweisen, der an einen Entlüftungsanschluss des Unterseebootes zum Beispiel ebenfalls mit einer Schnellkupplung angeschlossen werden kann. Über letztgenannten Anschluss an dem Entlüftungsanschluss des Unterseebootes kann verbrauchte Luft bzw. das in dem Druckkörper des Unterseebootes unerwünschte Ausatemgas CO2 aus dem Druckkörper des Unterseebootes herausgeleitet werden, wobei die verbrauchte Luft in dem Unterseeboot von der über den Belüftungsanschluss zuströmenden Frischluft ersetzt wird.Advantageously, the ventilation device can also be connected to a vent port of the submarine and thus also be designed for venting the submarine. That is, in addition to a connection to the submarine side ventilation port, the ventilation device may have a further port which can be connected to a vent port of the submarine, for example, also with a quick coupling. About the latter Following the venting connection of the submarine, spent air or the exhaled CO 2 gas undesirable in the pressure vessel of the submarine can be led out of the pressure hull of the submarine, the used air in the submarine being replaced by the fresh air flowing in via the aeration connection.
Bevorzugt ist vorgesehen, mit der erfindungsgemäßen Belüftungsvorrichtung die aus dem Druckkörper des Unterseeboots über den Entlüftungsanschluss herausgeleitete Luft direkt an das Umgebungswasser der Belüftungsvorrichtung abzugeben. Hierzu kann die Belüftungsvorrichtung zweckmäßigerweise in einem an dem Entlüftungsanschluss des Unterseebootes angrenzenden Leitungspfad einen Verdichter aufweisen, mit dem die aus dem Druckkörper des Unterseebootes abgeleitete Luft soweit verdichtet werden kann, dass sie gegen den in der Umgebung der Belüftungsvorrichtung herrschenden Wasserdruck aus der Belüftungsvorrichtung gepresst werden kann.It is preferably provided with the ventilation device according to the invention to deliver the air discharged from the pressure body of the submarine via the venting connection directly to the ambient water of the ventilation device. For this purpose, the ventilation device may expediently have a compressor in a conduit path adjoining the venting connection of the submarine, with which the air derived from the pressure vessel of the submarine can be compressed to such an extent that it can be pressed out of the ventilation device against the water pressure prevailing in the surroundings of the aeration device ,
Die Art des Antriebs eines solchen Verdichters ist prinzipiell beliebig. Beispielsweise kann ein elektrischer Antrieb vorgesehen sein. Allerdings ist es in diesem Fall erforderlich, eine elektrische Versorgungsleitung von dem Überwasserschiff zu der Belüftungsvorrichtung zu führen. Insofern ist es zweckmäßiger, wenn ein Druckluftmotor einen Antrieb des Verdichters bildet, wobei die zum Betrieb des Druckluftmotors benötigte Druckluft zum Beispiel über den an der Belüftungsvorrichtung angeschlossenen Versorgungsschlauch zu dem Druckluftmotor geleitet werden kann. Der Druckluftmotor kann als Kolbenmotor oder als Lamellenmotor ausgebildet sein.The type of drive of such a compressor is in principle arbitrary. For example, an electric drive can be provided. However, in this case it is necessary to lead an electrical supply line from the surface vessel to the aeration device. In this respect, it is more expedient if a compressed air motor forms a drive of the compressor, wherein the compressed air required for the operation of the compressed air motor can be routed to the compressed air motor, for example via the supply hose connected to the ventilation device. The compressed air motor may be designed as a piston engine or as a vane motor.
Zur Druckluftversorgung des Druckluftmotors kann vorteilhaft an dem Leitungspfad von dem Anschluss für die Versorgungsleitung zu dem Belüftungsanschluss des Unterseebootes eine Leitungsverzweigung zu dem Druckluftmotor vorgesehen sein. Dementsprechend kann ein Teil der von dem Überwasserschiff zu der Belüftungsvorrichtung geleiteten Druckluft in der Belüftungsvorrichtung zu dem Druckluftmotor geleitet werden. Dies ist insofern unproblematisch, als in der Belüftungsvorrichtung per se das Druckniveau der zugeführten Luft gesenkt werden muss, bevor die Luft über den Belüftungsanschluss des Unterseebootes weiter in den Druckkörper des Unterseeboots geleitet wird.For compressed air supply of the compressed air motor can advantageously at the line path from the connection for the supply line to the ventilation port of the submarine a branch line to the Be provided compressed air motor. Accordingly, a portion of the compressed air sent from the surface vessel to the aeration device in the aeration device may be directed to the air motor. This is unproblematic insofar as in the aeration device per se, the pressure level of the supplied air must be lowered before the air is passed through the ventilation port of the submarine further into the pressure hull of the submarine.
Bevorzugt ist bei Verwendung eines Druckluftmotors zum Antrieb des dem Entlüftungsanschluss des Unterseebootes in der Belüftungsvorrichtung nachgeschalteten Verdichters ein Luftauslass des Druckluftmotors mit dem Leitungspfad von dem Anschluss für die Versorgungsleitung zu dem Belüftungsanschluss des Unterseebootes leitungsverbunden. Dementsprechend ist vorgesehen, die zum Betrieb des Druckluftmotors zuvor in der Belüftungsvorrichtung abgezweigte Luft wieder zu dem Leitungspfad zu dem unterseebootseitigen Belüftungsanschluss zurückzuleiten.When using a compressed-air motor for driving the compressor downstream of the venting connection of the submarine, an air outlet of the compressed-air motor is preferably line-connected to the line path from the connection for the supply line to the ventilation connection of the submarine. Accordingly, it is provided to return the air branched off for operation of the compressed air motor in the ventilation device back to the line path to the submarine side ventilation connection.
Vorteilhafterweise kann die von dem Verdichter an die Umgebung der Belüftungsvorrichtung abgegebene Abluftmenge regelbar sein. Zu diesem Zweck kann vorzugsweise in der Leitungsverzweigung zu dem den Verdichter antreibenden Druckluftmotor eine Druckregeleinrichtung angeordnet sein, die mit einem eingangsseitig des Verdichters angeordneten Drucksensor signalverbunden ist. So kann mit dem Drucksensor der ausgangsseitig des Entlüftungsventils herrschende Druck der Abluft gemessen werden und die Leistung des Druckluftmotors und damit einhergehend die Leistung des Verdichters in Abhängigkeit von den von dem Drucksensor aufgenommenen Druckwerten von der Druckregeleinrichtung geregelt werden.Advantageously, the amount of exhaust air discharged from the compressor to the surroundings of the ventilation device can be regulated. For this purpose, a pressure regulating device may preferably be arranged in the line branching to the compressed air motor driving the compressor, which is signal-connected to a pressure sensor arranged on the input side of the compressor. Thus, the pressure of the exhaust air prevailing on the output side of the venting valve can be measured with the pressure sensor and the power of the compressed air motor and concomitantly the power of the compressor can be regulated by the pressure control device as a function of the pressure values recorded by the pressure sensor.
In einer weiteren vorteilhaften Ausgestaltung der erfindungsgemäßen Belüftungsvorrichtung kann in dem Leitungspfad von dem Anschluss für die Versorgungsleitung zu dem Belüftungsanschluss des Unterseebootes abströmseitig der Leitungsverzweigung eine Druckregeleinrichtung angeordnet sein. Diese Druckregeleinrichtung kann dazu dienen, die über die Versorgungsleitung vorzugsweise mit Hochdruck zur Verfügung gestellte Luft vor dem Erreichen des eingangsseitig des Belüftungsanschlusses des Unterseeboots angeordneten Verdichters bereits auf ein niedrigeres Druckniveau herunter zu regeln.In a further advantageous embodiment of the ventilation device according to the invention can in the conduction path of the connection for the supply line to the ventilation port of the submarine be arranged downstream of the line branching a pressure control device. This pressure regulating device can serve to regulate the air which is preferably made available at high pressure via the supply line before reaching the compressor arranged on the input side of the ventilation connection of the submarine already to a lower pressure level.
Bei der erfindungsgemäßen Belüftungsvorrichtung kann es beispielsweise dann, wenn eingangsseitig des Verdichters ein zu großer Druck herrscht, auch günstig sein, gegebenenfalls vor Erreichen des Verdichters einen Teil der von der Versorgungsleitung kommenden Druckluft an die Wasserumgebung der Belüftungsvorrichtung abzugeben. Hierzu kann vorteilhaft in dem Leitungspfad von dem Anschluss für die Versorgungsleitung zu dem Belüftungsanschluss des Unterseebootes ein Überdruckventil angeordnet sein, das beim Überschreiten eines maximal zulässigen Druckwertes öffnet und Luft in das Umgebungswasser abgibt. Typischerweise muss hierbei der Luftdruck eingangsseitig des Verdichters größer als der Wasserdruck sein.In the case of the ventilation device according to the invention, for example, if the pressure on the input side of the compressor is too great, it may also be favorable, if appropriate, to deliver part of the compressed air coming from the supply line to the water environment of the ventilation device before reaching the compressor. For this purpose, an overpressure valve can advantageously be arranged in the line path from the connection for the supply line to the ventilation connection of the submarine, which opens when a maximum permissible pressure value is exceeded and discharges air into the ambient water. Typically, the air pressure on the input side of the compressor must be greater than the water pressure.
Zweckmäßigerweise ist es bei der erfindungsgemäßen Belüftungsvorrichtung vorgesehen, sicherzustellen, dass der Schadstoffgehalt, der in dem Druckkörper des Unterseebootes befindlichen Luft bei dessen Be-und Entlüftung einen maximal zulässigen Wert nicht überschreitet. Daher können in dem an den Entlüftungsanschluss des Unterseebootes anschließenden Leitungspfad vorteilhaft Luftanalyseeinrichtungen angeordnet sein, mit denen die Zusammensetzung der aus dem Entlüftungsventil des Unterseebootes ausströmenden Luft ermittelt werden kann, wobei die erfindungsgemäße Belüftungsvorrichtung mit entsprechenden Steuermitteln so angesteuert werden kann, dass der Luftaustausch in dem Druckkörper des Unterseebootes bei einem zu hohen Schadstoffanteil der Luft beschleunigt wird.Conveniently, it is provided in the ventilation device according to the invention, to ensure that the pollutant content, the air in the pressure hull of the submarine air at its ventilation does not exceed a maximum allowable value. Therefore, in the adjoining the vent port of the submarine power line path advantageously air analysis devices can be arranged with which the composition of the effluent from the vent valve of the submarine air can be determined, the ventilation device according to the invention can be controlled with appropriate control means so that the air exchange in the pressure body the submarine is accelerated at a high pollutant content of the air.
Bei der erfindungsgemäßen Belüftungsvorrichtung kann es sich um eine separate Vorrichtung handeln, die auf einem Überwasserschiff zusammen mit dem an die Belüftungsvorrichtung anzuschließenden Versorgungsschlauch mitgeführt wird und im Havariefall eines Unterseebootes von einem Taucher oder Tauchroboter zu dem Unterseeboot geschafft wird und dort an dem Belüftungsanschluss und gegebenenfalls auch an dem Entlüftungsanschluss des Unterseebootes angeschlossen wird. Vorteilhafter kann die erfindungsgemäße Belüftungsvorrichtung allerdings Bestandteil eines Unterseebootes sein, also fest an der Außenseite des Druckkörpers, vorzugsweise in einem Bereich, in dem der Druckkörper außenseitig mit einer Außenhaut verkleidet ist, installiert sein. In diesem Fall ist es lediglich erforderlich, die von dem Überwasserrettungsschiff kommende Versorgungsleitung an dem entsprechenden Anschluss der Belüftungsvorrichtung anzuschließen.The ventilation device according to the invention may be a separate device, which is carried on a surface vessel together with the supply hose to be connected to the aeration device and in the event of a submarine accident is managed by a diver or diving robot to the submarine and there at the ventilation port and possibly also connected to the exhaust port of the submarine. Advantageously, the ventilation device according to the invention, however, be part of a submarine, so firmly on the outside of the pressure hull, preferably in a region in which the pressure body is covered on the outside with an outer skin, installed. In this case, it is only necessary to connect the supply line coming from the overwater rescue vessel to the corresponding connection of the ventilation device.
Nachfolgend ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. In der Zeichnungsfigur ist schematisch der prinzipielle Aufbau eines Unterseebootes mit einer daran angeschlossenen Belüftungsvorrichtung dargestellt.The invention is explained in more detail with reference to an embodiment shown in the drawing. In the drawing figure, the basic structure of a submarine with a ventilation device connected thereto is shown schematically.
Ein Unterseeboot 2 ist unterhalb der Wasseroberfläche 4 havariert. An der Außenseite eines Druckkörpers des Unterseeboots 2, der in der Zeichnung vereinfachend als Außenkontur des Unterseeboots 2 dargestellt ist, ist ein Belüftungsanschluss 6 und ein Entlüftungsanschluss 8 angeordnet.A
Zur Be- und Entlüftung des havarierten Unterseeboots ist eine Belüftungsvorrichtung 10 vorgesehen. Die Belüftungsvorrichtung 10 weist einen Anschluss 12 auf, an den eine Versorgungsleitung 12 in Form eines Schlauches 12 angeschlossen ist. Der Schlauch 12 führt zu der Wasseroberfläche zu einem dort schwimmenden Überwasserschiff, das in der Zeichnung nicht dargestellt ist. Über einen an Bord des Überwasserschiffes befindlichen Kompressor und/oder Druckgasflaschen wird Druckluft über den Schlauch 12 zu der Belüftungsvorrichtung 10 geleitet. In der Belüftungsvorrichtung 10 wird die Druckluft über eine Leitung 14 zu einem Anschluss 16 geleitet, der an den unterseebootseitigen Belüftungsanschluss 6 anschließbar ist.For ventilation of the damaged submarine a
In dem Schlauch 12 muss ein Luftdruck aufgebaut werden, der zumindest dem maximal auf die Außenseite des Schlauchs 12 wirkenden Wasserdruck entspricht. Würde die Luft mit diesem Druck in das Unterseeboot 2 geleitet werden, könnte dies ggf. für in dem Unterseeboot befindliche Personen gesundheitsschädigend sein. Daher ist in der Leitung 14 direkt eingangsseitig des Anschlusses 16 ein Druckminderer 18 angeordnet, mit dem die Luft auf einen akzeptablen Wert gesenkt wird. Der Druckminderer 18 wird vorzugsweise mit der Abluft des Druckluftmotors 28 versorgt. Sollte diese Abluftmenge nicht ausreichend sein, wird er über die Druckregeleinheit 20 direkt von der Versorgungsleitung 12 versorgt. Die Druckregeleinheit 20 regelt den Eingangsdruck aus der Versorgungsleitung 12 auf das Druckniveau der Abluft aus dem Druckluftmotor 28. Vor dem Erreichen des Druckminderers 18 wird der Luftdruck in der Belüftungsvorrichtung 10 bereits von einer in der Leitung 14 eingangsseitig des Druckminderers 18 angeordnete Druckregeleinrichtung 20 auf einen Mittelwert gesenkt.In the tube 12, an air pressure must be established, which corresponds at least to the maximum acting on the outside of the tube 12 water pressure. If the air were conducted with this pressure in the
Die Belüftungsvorrichtung 10 ist auch dafür vorgesehen, verbrauchte Luft aus dem Unterseeboot abzuführen. Hierzu weist die Belüftungsvorrichtung 10 einen Anschluss 22 auf, der an den Entlüftungsanschluss 8 des Unterseeboots 2 anschließbar ist. An den Anschluss 22 schließt sich innerhalb der Belüftungsvorrichtung 10 eine Leitung 24 an, die an der Wasserumgebung der Belüftungsvorrichtung 10 mündet. Über diese Leitung 24 wird die aus dem Unterseeboot 2 kommende Abluft an die Wasserumgebung abgeführt. Da die Abluft hierfür einen Druck aufweisen muss, der größer als der Wasserdruck in der Umgebung der Belüftungsvorrichtung 10 sein muss, ist in der Leitung 24 abströmseitig des Anschlusses 22 ein Verdichter 26 angeordnet.The
Der Verdichter 26 wird von einem Druckluftmotor 28 angetrieben. Zur Druckluftversorgung des Druckluftmotors 28 wird in der Belüftungsvorrichtung 10 ein Teil der über den Schlauch 12 zugeführten Druckluft abgezweigt. Zu diesem Zweck ist an der Leitung 14 eingangsseitig der Druckregeleinrichtung 20 eine Leitungsverzweigung vorgesehen, von der aus eine Leitung 30 zu dem Druckluftmotor 28 führt. Ausgangsseitig des Druckluftmotors 28 wird die dem Druckluftmotor 28 zugeführte Druckluft wieder der Leitung 14 zugeführt und dient somit der Belüftung des Unterseeboots 2. Hierzu ist an dem Druckluftmotor 28 eine Leitung 32 angeschlossen, die an der Leitung 14 in einem Bereich zwischen der Druckregeleinrichtung 20 und dem Druckminderer 18 mündet.The
Über eine Druckregeleinrichtung 34, die eingangsseitig des Druckluftmotors 28 in der Leitung 30 angeordnet ist, ist die dem Druckluftmotor 28 zugeführte Luftmenge und damit einhergehend die Leistung des Druckluftmotors 28 sowie die Leistung des Verdichters 26 regelbar. Diese Regelung erfolgt auf Grundlage des in der Leitung 24 eingangsseitig des Verdichters 26 herrschenden Drucks. Dieser Druck wird von einem Drucksensor 36 aufgenommen, welcher über eine Signalleitung 38 mit der Druckregeleinrichtung 34 signalverbunden ist.Via a
Übersteigt die Abluftmenge des Druckluftmotors 28 die über den Druckminderer 18 fließende Zuluftmenge, wird der Luftüberschuss über ein Überdruckventil 40 an die Wasserumgebung der Belüftungsvorrichtung 10 abgegeben. Das Überdruckventil 40 ist am Ende einer Leitung 42 angeordnet, die an der Leitung 14 zwischen der Druckregeleinrichtung 20 und dem Druckminderer 18 abzweigt.If the exhaust air quantity of the compressed air motor exceeds the supply air quantity flowing via the pressure reducer, the excess air is discharged via an overpressure valve to the water environment of the ventilation device.
