Description

The invention relates to a submarine according to the features indicated in the preamble of claim 1.

Particularly in the case of military submarines, it is state of the art to raise a so-called communication buoy from the submerged state to the water surface so that, depending on the equipment of the buoy, radio traffic, satellite navigation, optical observations and the like can be carried out on submerged submarines. Such communication buoys as well as generic devices for deploying and introducing a cable-controlled Kommunikationsboje are off EP 0 082 753 A1 . US 4,227,479 A and DE 101 15 194 A1 known.

From EP 0 082 753 A1 or US 3034471 Known communication buoy is mounted in a between the pressure hull of the submarine and a spaced apart from the pressure hull outer skin arranged obliquely to the rear of the submarine bearing storage container along with a cable winch. To bring the communication buoy to the water surface, the cable connected to the communication buoy on the cable winch is released, so that the communication buoy can move solely due to the forces acting on the communication buoy buoyancy forces from the container located between the pressure hull and the outer skin and rises to the water surface.

From US 4,227,479 A known Kommunikationsboje is mounted on a upper deck side of a submarine arranged recording and drives also solely buoyancy due to the water surface and is overtaken after collecting a cable connected to the communication buoy again in the outside of the submarine arranged recording.

In DE 101 15 194 A1 describes a spherical buoy, in which various antennas, sensors and communication means are united. This buoy is connected by a cable, which is intended for both data transmission and mechanical connection between buoy and submarine, with the submarine. The known device has a winch on the boat side, over which the cable is wound and the buoy is pulled into a funnel-shaped receptacle inside the hull, after which the receptacle is closed by means of a cover.

While deploying and retrieving the buoy from or into the buoy seat arranged inside the boat at substantially spherical trained buoys is usually no problem, is the direct extraction and insertion of a communication buoy in the in DE 101 15 194 A1 described way in communication buoys with a complex outer geometry difficult because these buoys are more prone to tilting in the outlet channel formed by the Bujenaufnahme.

For communication buoys of this type devices with arranged in the hull equipment carriers are known in which the equipment carrier can be spent for loading and unloading the buoys in a position outside of the hull. In this case, the equipment carrier is attached to such devices on a pivot arm with which it can be pivoted through an opening in the outer skin of the submarine to a position outside of the hull.

Although these devices allow a safe deployment and introduction of communication buoys, however, the disadvantageous is the relatively large space requirements of these facilities in the boat interior of the submarine.

Against this background, it is the object of the invention to provide a submarine in which a communication buoy in a position below an upper deck at the rear of the tower between the pressure hull and outer skin can be safely stored with low space requirements and deployed in a submerged state of the submarine and can be obtained again.

This object is achieved by a submarine with the features specified in claim 1. Preferred embodiments of the invention are set forth in the subclaims, the following description and the drawing.

The submarine according to the invention has a cable-controlled communication buoy, which in the non-active, i. is stored in unused condition in a storage position between the pressure hull and the outer skin in a device carrier. The storage position is a position below an upper deck provided at the rear of the tower of the submarine. Above this storage position, the outer skin of the submarine has a closable opening through which the equipment carrier for deploying or for retrieving the communication buoy is moved to a position outside the outer skin. In this position, the application and retrieval of the communication buoy is carried out in the usual way by unwinding or winding the guide cable from or to a winch.

According to the invention means are provided for translational movement of the equipment carrier, with which the equipment carrier from the storage position to a position for insertion and removal of the communication buoy on the outside of the outer skin and vice versa is movable. Unlike in previously known devices for deploying and retrieving communication buoys in which the equipment carrier is spent with a relatively much space consuming pivotal movement from the storage position to the outer position and vice versa, it allows the inventive design, the equipment carrier and the communication buoy thereon to move in a direct straight path from the storage position to the position outside the outer skin and vice versa from the outer position to the storage position. Accordingly, the equipment carrier according to the invention can be moved from a position in the vicinity of the pressure body in a rectilinear motion normal to the pressure body by a direct over the device carrier on the outer skin provided opening to a position outside the outer skin and back.

As a means for translational movement of the device carrier are basically all linear drives conceivable. Preferably, however, the implement carrier is operatively connected to at least one hydraulically actuable lifting cylinder. Here, the device carrier may be guided in a guide in the extension or retraction, wherein the force is exerted to move the device carrier via a directly or indirectly acting on the device carrier lifting cylinder. Advantageously, the lifting cylinder but even the leadership of the device carrier. For this purpose, the equipment rack is conveniently mounted directly on the extendable end of the lift cylinder. The movement of the device carrier follows in this case immediately the extension movement of the lifting cylinder. Because of the relatively small distance of the pressure body and outer skin of the lifting cylinder is advantageously designed as a telescopic cylinder, which allows large strokes at a relatively low installation height. Thus, the design of the lifting cylinder as a telescopic cylinder on the one hand provides the ability to store the device carrier with the communication buoy located on the buoy cylinder between the pressure hull and outer skin of the submarine space-saving, on the other hand allows the telescoping of the lifting cylinder sufficient stroke around the equipment carrier with the communication buoy in a position outside the outer skin of the submarine.

Since the lifting cylinder is claimed at both outside of the outer skin device carrier both flow forces and by the force exerted by the guide cable forces, it is advantageously dimensioned and designed so that it can absorb these acting as lateral forces loads and associated moments. In an advantageous development, a support is provided for this purpose, which supports the lifting cylinder transversely to its extension direction. The support is suitably arranged and designed so that acting on the lifting cylinder transverse forces and moments transmitted from the lifting cylinder on the support and from there into the pressure hull or possibly in a pressure-body side arranged foundation of lifting cylinder and support can be forwarded.

In order to prevent unintentional displacement of the communication buoy in the storage position, the invention provides distributively gripping means which fix the communication buoy in the equipment carrier in the storage position at least in a form-fitting manner. Accordingly, at least two opposing mechanical gripping arms are provided, which grasp a region of the communication buoy at substantially diametrically spaced sides and fix in a form-fitting manner, optionally additionally in a non-positive manner.

The gripping means are preferably formed hydraulically actuated. As a gripping means, for example, parallel gripper can be used, in which two parallel aligned gripping arms for gripping the communication buoy are linearly movable toward each other. The gripping means preferably have at least one hydraulically actuable angular gripper. Thus, on the pressure-body side in the storage position of the communication buoy, the gripper arms forming the angle gripper can be provided which, when pivoted towards one another, engage around and hold a portion of the communication buoy located in the storage position.

To protect the device carrier and the communication buoy mounted thereon against a shock load caused by pressure waves, the device carrier is expediently mounted elastically on the pressure body of the submarine. The elastic and shock-proof storage of the device carrier is preferably carried out indirectly, for example by elastic support of the means for translational movement of the device carrier. In this case, as provided in a preferred embodiment, a linear drive, preferably a hydraulic telescopic cylinder, on which the device carrier is mounted, be arranged on a foundation, which in turn is arranged on the pressure body, wherein spring and / or damping elements are provided between the foundation and the pressure body. Conveniently, the gripping means for fixing the communication buoy in the storage position are then arranged on this foundation.

The device carrier preferably has at least one guide roller for guiding the guide cable of the communication buoy. The guide roller is preferably arranged on the side of the device carrier, which faces the arranged on the pressure hull winch for removal and insertion of the guide cable. Between the winch and the equipment carrier, it forms a deflection roller by means of which the alignment of the guide cable from a first direction on the windage side of the equipment carrier is deflected in a second direction on the side of the device carrier. Since a transverse force component of the tensile force exerted on the guide cable acts on the linear drive, the deflection roller or the deflection rollers can be arranged on the equipment carrier such that the transverse force component acting on the linear drive of this tensile force is as small as possible. In addition, however, such an arrangement of the deflection roller or pulleys is conceivable in which in the linear drive targeted such a transverse force component is introduced, which is directed counter to the linear force caused by the flow of the equipment carrier transverse force and so at least partially compensated.

In a further advantageous embodiment of the invention, the outer skin side of the submarine articulated at least one pivot arm which is arranged and pivoted so that it presses when hauling a Kommunikationsboje this immediately before reaching the equipment carrier in a storage seat of the equipment carrier. The aim of this embodiment is the communication buoy when catching on can strike the equipment carrier obliquely, align it so that it forms a positive connection with this bearing seat in the bearing seat of the equipment carrier in a defined position.

The provided above the equipment carrier opening in the outer skin of the submarine, through which the equipment carrier is moved to a position outside the outer skin is advantageously closed with at least one flap, which is operatively connected to a hydraulic rotary cylinder. For this purpose, the rotary cylinder is coupled to the flap, that the rotational movement of the movable part of the rotary cylinder is transmitted to the flap. Conveniently, two flaps are provided with associated rotary cylinders, wherein the flaps are arranged so that they are flush in the closed position with the outer skin.

To prevent accidental or external exposure, e.g. To prevent the flap opening closing the outer skin opening caused by the sea state, each flap is expediently hydraulically lockable. For this purpose, on the flap side and on the outer skin side locking components may be provided, wherein by means of hydraulically actuatable actuators e.g. a positive connection between a flap and the outer skin or a positive connection between the valves can be produced.

FIG. 1 shows the submarine 2 according to the invention in the submerged state below the water surface 4. In the illustrated submarine 2, a gear tray 6 is extended for a communication buoy 8 by a rear side of the tower 10 of the submarine 2 arranged opening of the outer skin in a position outside of this outer skin. The communication buoy 8 is shown floating in its deployed state on the water surface 4. The communication buoy 8 is connected to a guide cable 12, which has been drained from a wind inside the boat 14, which is arranged on the rear side of the tower 10 in the direction of travel in front of the equipment carrier 6. By means of the guide cable 12, the communication buoy 8 with the submarine 2 is both mechanically and data-connected.

In Fig. 2 the communication buoy 8 is shown mounted in a below one of two flaps 16 closed opening of the outer skin of the submarine 2 arranged equipment carrier 6 stored. The pivot axes of the flaps 16 are formed by pins 18 which protrude outwardly at the side surfaces of the flaps 16 aligned parallel to the pivot plane, wherein the two pins have a common axis. The pins 18 are rotatably mounted in bearings 20 which are arranged in the opening-limiting region of the outer skin. At a respective pin 18 of the flaps 16 engages a hydraulically actuated rotary cylinder 22, with which the flap 16 in a the outer skin releasing or closing position can be pivoted.

The communication buoy 8, the best in Fig. 3 is visible, has a float 24, on the upper side of an antenna body 26 for receiving various receiving and transmitting antennas and sensors of the communication buoy 8 is arranged. The antenna body 26 is formed foldable and can in the storage position of the communication buoy 8 in a voltage applied to the float 24 position ( Fig. 1 ) and how in Fig. 2 shown, are folded into a functional position in which the antenna body 26 is substantially upright on the float 24. At the bottom of the floating body 24 a keel sword is arranged, which has at its end a barrel-shaped extension 28 in the form of a ballast receiving keel fin.

The Fig. 2 and 3 show the communication buoy 8 stored on the equipment rack 6. The device carrier 6 has a receptacle 30 which forms a bearing seat corresponding to the outer contour of the floating body 24 of the communication buoy 8, in which the floating body 24 rests. The receptacle 30 projects horizontally on a fastening component 32, with which the equipment carrier 6 is attached to the extendable ends of two juxtaposed lifting cylinder 34.

The lifting cylinder 34 are formed multi-stage telescopic. By extending the lifting cylinder 34 of the equipment carrier 6 with the communication buoy located thereon 8 of a storage position between the pressure hull and the outer skin of the submarine 2 in an in Fig. 3 shown position outside the outer skin translationally movable. The lifting cylinders 34 are arranged vertically standing on a foundation 36. The foundation 36 is standing on substantially U-shaped leaf spring elements 38 standing on the pressure hull of the submarine 2 arranged and stored in this way spaced from the pressure body shockproof.

Also standing on the foundation 36, a frame 40 is arranged on the side remote from the equipment carrier 6 side of the lifting cylinder 34, which serves as a support for the lifting cylinder 34. The frame 40 is formed by two triangular steel frames 42 which are interconnected by means of transverse struts 44 and 46. The lifting cylinder 34 are each supported by cross struts 48 on one of the steel frame 42 of the frame 40. At the two steel frame 42 connecting cross member 44 is a guide roller 50 rotatably mounted, with which in the Fig. 2 and 3 not shown guide cable 12 coming from the winch 14 is deflected in the direction of the equipment carrier 6.

In addition to the guide roller 50 arranged on the frame 40, two further guide rollers 52 and 54 for guiding the guide cable 12 are provided on the equipment carrier 6. These guide rollers 52 and 54 are arranged on the side facing away from the receptacle 30 side of the fastening member 32 of the device carrier 6.

Below the equipment carrier 6, an angle gripper 58 which can be actuated by means of hydraulic cylinders 56 is arranged on the foundation 36, with which the communication buoy 8 can be fixed in a form-fitting manner in the storage position. The angle gripper 58 has two pivotable gripper arms 60, on which gripping jaws 62 are arranged, which are formed corresponding to the outer shape of the communication buoy 8 in the region of the extension formed on the keel blade extension 28.

On the outside of the flaps 16, which close the outer skin opening of the submarine 2, a pivot arm 64 is articulated on the outer skin. This pivot arm 64 forms an integral part of the outer skin. By pivoting the pivot arm 64, the communication buoy 8 can be pressed during the Einholvorgangs immediately before reaching the device carrier in the storage seat formed by the receptacle 30. For actuating the swivel arm, a hydraulic rotary cylinder 66 is provided.

Hereinafter, the deployment and subsequent recovery of a communication buoy 8 in the submarine 2 according to the invention will be described. The communication buoy 8 is in the in Fig. 2 storage position between pressure hull and outer skin of the submarine 2. The outer skin opening located above the equipment carrier 6 is closed by the two flaps 16. The flaps 16 are locked by means not shown in the figures hydraulically actuated locking means. To deploy the communication buoy 8, this locking of the flaps 16 is first released, whereupon the flaps 16 are swung over the rotary cylinder 22. Subsequently, the angle gripper 58 is actuated and the gripping arms 60 is pivoted into a position on the communication buoy 8 extension 28 releasing position. By extending the lifting cylinder 34, the equipment carrier 6 is now spent with the communication buoy thereon 8 in a position outside the outer skin of the submarine 2. After unfolding the antenna body 26, the guide cable 12, to which the communication buoy 8 is connected, from the in Fig. 1 outlined winds 14 and the communication buoy 8 floats by own buoyancy to the water surface 4.

To obtain the communication buoy 8, the guide cable 12 is wound on the winch 14 and the communication buoy 8 is pulled in the direction of the equipment carrier 6. After the communication buoy 8 has reached the equipment rack 6, the lifting cylinder 34 are retracted. The communication buoy 8 is then below that of the flaps 16 closable outer skin opening. Now, the pivot arm 64 is actuated and pivoted so that it first folds the antenna body 26 in a voltage applied to the float 24 of the communication buoy position and then presses the communication buoy 8 in the receptacle 30 in the bearing seat. Subsequently, the angle gripper 58 is actuated and the gripping arms 60 are pivoted into a position in which the grip jaws 62 arranged on the gripper arms 60 comprise the extension 28 formed on the communication buoy 8 in a form-fitting manner. Finally, the flaps 16 are pivoted and locked in the position closing the outer skin opening.
