Description

The invention relates to a device for storing and deploying submerged bodies in a submarine with the features specified in the preamble of claim 1.

In modern submarines, it is customary to provide devices outside the pressure hull in which immersion bodies, such as, for example, effectors for torpedo defense, are stored in tubular storage containers. At the same time, these devices also serve to deploy the immersion bodies, which are ejected for this purpose from the storage containers.

Because of the increasing pressure with increasing depth of the storage container, it is customary to design these so that they allow a pressure equalization between the internal and the ambient pressure of the storage container. This is how, for example, in DE 100 31 409 described in known devices of the type in question, at least one opening of the storage container sealed with a membrane and filled the interior of the storage container next to the immersion bodies therein with a liquid. This is typically a liquid that protects the immersion body from corrosion. In particular, in such devices for the storage of immersion bodies, which are arranged on the submarine in the region of the upper deck and are therefore located in submerged submarine above the water surface, is Usually used glycol as a filling liquid for the storage container, which is virtually frost-proof.

The loading of such storage containers with immersion bodies is expensive, in particular because of the subsequent filling with the protective liquid. This is due to the requirement to accurately measure the amount of liquid, as too large or too small amount of liquid under appropriate temperature conditions would either expand or contract to an acceptable level, which destroy the membrane occluding the storage container and as a result damage to the Can lead immersion body.

Against this background, it is the object of the invention to provide a device for storing and dispensing submerged bodies, which can be fitted in a simple manner with the submerged bodies, in which the submerged bodies are stored safely and in addition allows reliable deployment of the submerged bodies ,

This object is achieved by a device having the features specified in claim 1. Advantageous developments of the invention will become apparent from the dependent claims, the following description and the drawings.

The device according to the invention for storing and deploying immersion bodies, in particular for storing and deploying effectors, in a submarine has at least one tubular storage container for a submersible located outside the pressure hull of the submarine. In addition, the device has means for discharging the immersion body. Significant for the device according to the invention, the storage container forms a pressure-resistant pressure body.

Accordingly, the outer wall and container openings closing lids, seals and closures of the storage container are designed and dimensioned such that they grant a flameproof enclosure of the immersion body in the storage container at any intended depth of the submarine.

In this way, the device according to the invention makes it possible to store an immersion body and typically a plurality of immersion bodies on the outside of the pressure hull of a submarine in one or more storage containers dry and under pressure conditions which correspond to those on the water surface. That is, the immersion body is exposed during storage in the storage container neither a compressive stress nor a liquid, which increases the life or usability of the immersion body and in particular the life and operability of effectors. Further advantageously eliminated in the inventive device that consuming filling the storage salaries with a protective liquid, which greatly simplifies the loading of the device with the or the diving bodies.

The preferably each associated with a storage container means for discharging the immersion body from the storage container preferably each have a cylinder in which a piston is movably guided. This piston is movable by pressurization by a pressure medium, which may be a liquid or a gas. By means of a traction means, the piston is motion-coupled with a submersible located in the storage container.

In this embodiment, the cylinder is expediently line connected to a pressure accumulator. This accumulator is preferably designed as a piston accumulator, in which the in the piston-cylinder arrangement to move the piston to be introduced pressure medium, which is preferably a glycol-water mixture is stored in a pressure storage chamber. This glycol-water mixture can be pressed into the cylinder by pressurizing a piston provided in the pressure accumulator by means of a further pressure medium, preferably nitrogen, whereby the piston located there moves for the purpose of discharging the immersion body.

Preferably, the cylinder, which is provided for discharging the immersion body, has a longitudinal slot through which a projection projecting on the outside of the piston is guided, at the end of which a deflection roller is arranged on the outside of the cylinder. The longitudinal slot on the cylinder can be advantageously sealed with a lip seal, which is pressed by means of the pressure medium filled in the cylinder against the inner wall of the cylinder, wherein it covers the slot sealing.

About the deflection roller, the traction means is guided, with which the piston is coupled in motion with the immersion body. The traction means is preferably a cable whose one end is fastened to the device and the other end of which is guided in a pressure-tight manner into the storage container and fastened there to a driver arranged on the rear side of the immersion body therein. The driver is guided here in the storage container movable. By moving the piston in the cylinder and concomitantly by moving the deflection roller, the traction means is tensioned and located in the storage container end of the traction means with the driver disposed thereon including the immersion body in the direction of a discharge opening of the storage container until the immersion body is discharged from the storage container.

Conveniently, the movement-fixed device-side attachment of the traction means and the direction of movement of the piston with the deflection roller arranged thereon are selected such that the path of travel of the carrier in the storage container is doubled with respect to the movement path of the piston in the cylinder. This makes it possible, as provided in a further advantageous embodiment, to limit the path of movement of the piston in the cylinder. In this way it is prevented that the piston is moved out of the cylinder, which could lead at worst to an influence or damage to an already located outside of the storage container immersion body.

Preferably, the path of movement of the piston is limited by means of a collecting tube located within the piston, which is expediently closed at its end remote from the piston. When the piston reaches the collecting tube, it is slowed down and finally brought to a standstill.

In order to be able to flood the interior of the storage container according to the invention, which is liquid-free in the storage state, quickly and immersion-independently before applying the immersion body, appropriate means for flooding the storage container are provided.

Thus, at least one valve is advantageously provided for flooding the storage container, by means of which the water surrounding the storage container in the submerged state can flow into the storage container after actuation of the valve. Preferably, the valve can be actuated by means of a pressure medium, wherein for the actuation of the valve particularly advantageous the pressure medium is used, which otherwise for. Pressurization of the piston is provided for discharging the immersion body.

According to a development of the device according to the invention, an opening of the storage container can be closed by means of a lid which forms a valve body. Preferably, this cover closes one of the two end faces of the tubular storage container, wherein the lid is pressed only by means of a frictional connection, for example by means of a spring bias, in a pressure-tight closing the end-side opening of the storage container position. At the same time, means are expediently provided in this development, with which preferably by means of a pressure medium a frictional force directed against the lid can be exercised, which moves the lid in a position releasing the container opening, in which the surrounding storage container water can penetrate into this ,

Advantageously, the cover closing the opening of the storage container forms a piston-cylinder arrangement with a fixed piston and a movable cylinder. Accordingly, the lid, which forms the valve body in this embodiment, at least a hollow cylindrical portion in which a piston is guided. Together with a closure closing the hollow-cylindrical area on one side, the piston defines a cylinder chamber which can be pressurized and expediently pressurizes it to move the cylinder, ie. H. the lid leads into a position releasing the container opening, so that water can penetrate into the storage container via a gap formed between the storage container and the lid.

For discharging the immersion body, a further opening of the storage container, which forms its ejection opening, preferably closed with a lid, which is movable by means of the piston-cylinder arrangement in a position releasing the ejection opening. For this purpose, the pressure-tight closing the discharge opening lid with the cylinder motion-coupled. For example, the cover closing the discharge opening may be pivotally mounted on the storage container and connected to the cylinder by means of a linkage. This linkage transmits the movement of the cylinder to flood the storage container in a pivoting movement of the cover closing the discharge opening.

The storage container is preferably formed as a double-walled tube, d. h., The storage container has an outer tube in which an inner tube, which serves for the actual storage of the immersion body, is arranged. In this embodiment, the inner tube is preferably spaced from the outer tube, so that between the inner and outer tube, an annular gap is formed. Further advantageously, the inner diameter of the inner tube or the inner diameter of an inner lining of this tube corresponds to the outer diameter of the immersion body. In order to minimize the volume to be irrigated in the storage container for dispensing the immersion body, the inner tube is preferably sealed on both sides with respect to the outer tube, so that the annular gap between the two tubes does not have to be flooded.

To store the immersion body in the storage container shockproof, the inner wall or the inner tube is advantageously mounted elastically in the outer wall or in the outer tube of the storage container. The elastic mounting of the inner tube is advantageously carried out via spring or damping elements, which are arranged in the annular gap between the inner and outer tube.

Further advantageously, the invention provides that in the device for storing and deploying immersion bodies at least one storage container and typically a plurality of storage containers are arranged in a frame, which is a removable upper deck segment of the submarine. This embodiment advantageously makes it possible to equip the storage containers away from the submarine, for example on land or on an overwater support ship of the submarine.

Fig. 1 shows a tubular storage container 2 of the device according to the invention for storing and dispensing submerged bodies, in which an effector 4 is mounted for torpedo defense. The storage container 2 is designed as a double-walled tube with an inner wall 6 and an outer wall 8. The inner wall 6 and the inner tube 6 forms the storage space for the effector 4 and also serves to guide the effector 4 during its ejection movement. The inner diameter of the inner tube 6 corresponds approximately to the outer diameter of the effectors 4th

The two walls 6 and 8 of the storage container 2 are spaced apart by an annular gap 10. In the annular gap 10 damping elements 12 are arranged, which comprise the outer circumference of the inner wall 6 annular. On these damping elements 12, the inner wall 6 and, consequently, the effector 4 located therein on the outer wall 8 is elastic and thus stored shock-proof. Elastic sealing rings 14 seal the annular gap 10 between the inner wall 6 and the outer wall 8 at both ends of these walls 6 and 8 liquid-tight. Starting from the effector 4 stored in the storage container 2, the bow side of the effector 4 arranged end face of the storage container 2, which forms the ejection opening for the effector 4, provided by a cover 16 and the rear side of the effector 4 on the front side opening of the storage container 2 of a lid 18 sealed pressure-tight. A more detailed description of the lid 16 and 18 is made later on the basis of Figures 2 and 3 ,

In the immediate vicinity of the storage container 2, a hollow cylinder 20 is arranged parallel to this, in which a piston 22 is movably guided. Based on the storage container 2 closes at the Hollow cylinder 20 in the vicinity of the lid 18 of the storage container 2, a distributor housing 24 with a pressure medium distributor 25 arranged therein, which is provided with a in Fig. 4 shown pressure accumulator 26 is connected by lines. From this pressure medium distributor 25, a line 28 leads into the hollow cylinder 20. In this line 28 and the pressure medium distributor 25 of the hollow cylinder 20 is conductively connected to the pressure accumulator 26 so that stored in the pressure accumulator 26 pressure medium, such as a glycol-water mixture in the Hollow cylinder 20 can be passed. As a result, the piston 22 is moved in the hollow cylinder 20 in the direction of the closed by the lid 16 ejection opening of the storage container 2. In the direction of movement of the piston 22 behind the hollow cylinder 20 is spaced from this a collecting tube 30 is arranged, which is closed away from the hollow cylinder 20 end. In the collecting tube 30, caused by the pressure medium movement of the piston 22 is braked and finally stopped, wherein the piston 22 is still largely located in the hollow cylinder 20, and prevents excessive leakage of the pressure medium from the hollow cylinder 20.

The piston 22 is coupled by means of a cable 32 to the effector 4 located in the storage container 2. This motion coupling is described below with reference to Figures 2 . 3 and 4 described in more detail. How the particular Fig. 4 can be seen, the hollow cylinder 20, in which the piston 22 is arranged, a longitudinal slot 34. Through this longitudinal slot 34, a projection 36 is guided, which projects radially outward on the piston 22. Outside the hollow cylinder 20, a deflection roller 38 is attached to the projection 36, which is coupled in this way with the piston 22.

On the outside of the hollow cylinder 20, a second deflection roller 40 is attached in the immediate vicinity of the distributor housing 24. Another deflection roller 42 is on the storage container 2 outside the discharge opening 2 arranged. The cable 32 is fastened to a cable terminal 44 arranged on the distributor housing. From there, the cable 32 is first on the disposed on the piston 22 guide roller 38, from there back to the arranged in the vicinity of the distributor housing 24 guide roller 40 and then via the guide roller 42 in the storage container 2 in the direction of the lid 18 closed end face where it ends at a cable terminal 46 of a driver 48, which serves for discharging the effector 4 from the storage container 2. The driver 48 is arranged in the storage container 2 such that it engages a formed on the effector 4 tail fin 50.

At the storage container 2, a pipe flange 52 forms the discharge opening closed by the cover 16. Through this pipe flange 52, the rope 32 is guided over a cable guide 54 formed there in the interior of the storage container 2. In order to prevent ingress of water in the storage container 2 via the cable feedthrough 54, a sealant is vulcanized on the cable 32, that the cable feedthrough 54 together with the cable 32 closes liquid-tight.

How out Fig. 4 shows, the effector 4 is not directly on the inner circumference of the wall 6 but on an inner lining 56 arranged thereon. At this inner lining 56, a groove 57 is formed, which extends in the longitudinal direction of the inner wall 6 and which serves to guide the cable 32 and the driver 48 in the storage container 2.

In order to be able to irrigate the storage container 2 before applying the effector 4, 2 valves are provided on the storage container as a means for flooding the storage container 2. Thus, on the lid 18 valves 58 and the ejection opening of the storage container 2 forming pipe flange 52, a valve 60 is arranged, through the opening of which water can flow into the interior of the storage container 2.

In addition, the lid 18 itself forms a valve in the form of a piston-cylinder arrangement with a relative to the storage container 2 fixed piston 62 and with a relative to the piston 62 and the storage container 2 movable cylinder 64 which can be moved to a position in which he at least partially releases the otherwise closed by the lid 18 opening of the storage container 2. The stationary arrangement of the piston 62 via a piston 62 outgoing from the piston rod 66 which is connected to a storage container side arranged frame 68. In this case, the attachment of the frame 68 to the storage container 2 follows a arranged on the outer wall 8 of the storage container 2 tube flange 70. To the piston rod 66, a coil spring 78 is arranged, on the one hand on the cylinder 64 forming portion of the lid 18 and on the other is supported on a formed on the piston rod 66 paragraph 80.

On the lid 18, a cylinder chamber 72 is formed. By the piston rod 66, a line 74 is guided. Via bores 76, which open on the one hand in the line 74 and on the other hand in the cylinder chamber 72, the cylinder chamber 72 can be printed with a printing medium. The starting point of the line 74 forms the pressure medium distributor 25, via which also the hollow cylinder 20 is supplied with the pressure medium.

In the region of a wall of the cylinder chamber 72 opposite the piston, bores are provided in which pins 82 are movably guided, one end of each of the pins 82 protruding on the outside of the cover 18. About these ends, the pins 82 each with a leaf spring formed by a spring plate 84, the one-sided is attached to the outside of the lid 18, connected. The radially outside of the pins 82 arranged valves 58 are also connected to the spring plate 84.

In the pipe flange 52 which forms the discharge opening of the storage container 2, a ring line 86 is formed, which is fluidly connected to the line 28 opening into the hollow cylinder 20. In the ring line 86 opens a bore in which a pin 88 is movably mounted, wherein one end of this pin 88 protrudes on the outside of the pipe flange 52. This end of the pin 88 is like the valve 60 connected to a spring plate 90 which, like the spring plates 84 forms a leaf spring.

In addition, a hinge 92 is provided on the pipe flange 52 to which the lid 16 is pivotally connected via a lever 94 fixed to the cover 16. A free end of the lever 94 is pivotally mounted to a linkage 96, wherein the linkage 96 in turn is connected to the cylinder 64 forming part of the lid 18.

Hereinafter, the application of an effector 4 from the storage container 2 will be described.

First, the storage container 2 is closed by the lids 16 and 18 pressure-tight. Then, a portion of the pressure medium in the pressure accumulator 26 is passed via the line 74 and the bores 76 extending therefrom into the cylinder chamber 72 formed on the lid 18, which leads there to an increase in pressure. As a result, the pins 82 in the holes in which they are movably guided, further pushed outwardly and the valves 58 moves over the spring plates 84 in a position in which a flow path through the valves 58 from the environment of the storage container 2 in the interior of the storage container 2 is released, so that water can flow through the valves 58 in the storage container 2.

As soon as the pressure medium flowing into the cylinder chamber 72 has built up a pressure therebetween which exceeds the spring pressure of the coil spring 78 acting from outside on the cover 18 and the water pressure, the cylinder chamber 72 expands by the part of the cover 18 forming the cylinder 64 of its the storage container 2 firing position is moved away and more water can flow into the storage container 2. In addition, we transferred the movement of the cylinder 64 via the linkage 96 on the lever 94 and the lid 16 swung open. Previously, by pressurizing the ring conduit 86, the valve 60 has been moved by movement of the pin 88 over the spring plate 90 in a position releasing a flow path into the interior of the storage container.

Once the lid 16 has been pivoted at the discharge opening of the storage container 2 in its ejection opening releasing position, the pressure medium is introduced via line 28 into the cylinder 20 and the piston 22 located there in this way set in motion until it is decelerated in the output tube 30 or is stopped. By the movement of the piston 22 located in the storage container 2 end of the rope 32 is pulled with the driver 48 attached thereto in the direction of the discharge opening of the storage container 2 and the effector 4 transported out of the storage container 2.

The Fi. 5 and 6 show an embodiment of the device according to the invention in which three storage containers 2 and 2 'are arranged in a frame 98, in which immersion bodies 4 and 4' are arranged. The storage containers 2 and 2 'and the immersion bodies 4 and 4' mounted therein differ only with respect to their Size. In Fig. 5 the device is shown exploded from their mounting position in a submarine exploded. The device forms a removable upper deck segment of the submarine.

On the pressure body 100 of the submarine 102 foundations 104 are arranged below an upper deck, which serve for receiving formed on the frame 98 feet 106 feet. In this case, the feet 106 rest on damping elements 108 arranged on the foundations 104. Furthermore, locking elements 110 are provided on the foundations 104 with which the device is fastened to the pressure body 102 of the submarine.

The frame 98 is covered with a lining 112, whose contour corresponds to the cross-sectional contour of the outer skin of the submarine in the region of the upper deck 102. Complementary to the ejection direction and size of the immersion bodies 4 and 4 ', the covering 112 openings, which are closed by flaps 114 and 114'. Flaps 114 and 114 'are pivotally hinged to cowling 112 and operable via actuating rods 116 and 116', respectively, which form an extension of linkage 96.
