The present invention relates to an apparatus for subtracting traction antennas or traction cables from the water surface in an underwater boat, in particular a submarine.

Background of the Invention Devices for subtracting antennas, cables and the like from submarines are already known. In this regard, reference is made to European Patent Application No. 0 124 133 and German Patent No. 196 52 737. Antennas / cables that are removed during operation and then reinserted are installed in the submarine for numerous purposes. In this case, it is divided into an antenna / cable that sinks underwater, an antenna / cable that floats over water, and a floating antenna / cable. Floating antennas are typically used for communication, navigation and monitoring. In order to withdraw the antenna from the danger zone in contact with the submarine according to the angle of traction set, the antenna is installed at the traction point of the submarine, usually at the rear edge of the submarine upper deck.

Control of the submarine even when the antenna is pulled out because the draw point is placed below the propeller's radius of rotation so that floating antennas, such as those provided for submarine ultrasonic detection, can be sent from the back of the submarine to the detection zone without damage and without obstruction. This is not very limited. That is, the risk of the antenna being swept into the propeller is as low as possible. Thus, such an antenna is typically placed in front of the direction key.

It is already known to pull the antenna out of a separately installed guide stand to ensure sufficient spacing between the propeller and the antenna. However, in such a guide stand, there is a disadvantage that the stand has an undesirable effect on the hydrodynamic profile of the submarine and further generates a mark. Alternatively, the abandonment of such guidestands, which adversely affect the hydrodynamic and acoustical properties of the submarine, raises the problem that the number of draw points used is numerically limited, reducing the use of antennas or cables instead. .

The object of the present invention, based on the prior art, eliminates the above mentioned drawbacks and withdraws multiple antennas or cables anywhere in the submarine without significantly affecting the hydrodynamic and acoustic properties of the submarine. It is to make a device for.

The problem is solved by the features described in claim 1 according to the invention. Preferred embodiments of the invention are presented in the dependent claims and the following description and drawings.

The basic idea of the present invention is to provide a guide for an antenna or cable that can be changed to at least two positions, i.e. two positions where the acoustic and hydrodynamic characteristics of the submarine are significantly affected by the guide portion inside the submarine's envelope. The first non-operating position, which is not received, and the guide portion are located outside the submarine's envelope, so that the antenna or cable is secured to the submarine hull so that it can be reliably escaped from the danger zone of the propeller without excessively limiting the submarine's maneuverability. It is a second operating position to guide at a sufficient distance.

Thus, the present invention includes the advantages as known by known guide stands on the submarine envelope. That is, in order to guide the antenna or cable at a sufficient interval with respect to the submarine hull, there is an advantage that the guide portion can be arranged in any part of the hull and the guide portion can be formed sufficiently long. Furthermore, the guide part according to the invention likewise scratches in the operating position and also affects the hydrodynamic properties of the submarine, but this is not a problem, since the antenna or cable is pulled out and the maneuverability of the submarine corresponds to a predetermined interval. This is because such a problem appears only when the runability is limited. It is important, however, that the hydrodynamic and acoustic properties of the submarine are not significantly affected when the antenna or cable is inserted, i.e. during normal driving, inside the submarine shell, if the guide section-if the guide section is in the inoperative position.

It is structurally preferable that the guide portion is pivotally installed, in which case the guide portion is positioned approximately parallel to the submarine envelope at the inwardly pivoted position, thus space-saving arrangements, especially in submarines, between the pressure hull and the shell. Because it is possible. Alternatively, in the pivoted outward position, almost the entire length of the guide portion can be used to space the cable or antenna from the submarine. Corresponding means are provided to implement the inward and outward swing operation, typically a lever mechanism that can be controlled from inside the submarine and can be hydraulically or electrically operated.

In order to be able to space the antenna or cable as far as possible even though the device according to the present invention is arranged in a space-saving manner inside the submarine hull, a guide part can be built according to an embodiment of the present invention and then projected outward again. It is preferable to form in an telescopic manner.

In order for the guide portion to stay in its operating position while the antenna or cable is pulled out, the guide portion is in at least one operating position, preferably in the final position or in any operating position, i.e. any swinging position or embedded position. A fixing device is provided that can be fixed.

It is preferable to provide a guide roller at the end of the guide portion so that the antenna or cable can be removed without any friction and then inserted again. These rollers are rotatably supported and the antenna or cable is moved over the rollers.

Preferably, the guide is not only fixed in the operating position but also locked mechanically. Such mechanical locking can be achieved by means of a corresponding lever mechanism which is configured to be locked by self locking in the outwardly pivoted position, ie in the final position of the guide. In this case, there is no possibility that the guide portion is inadvertently swung inward even by an external influence, for example, a fluid influence.

Preferably, the guide portion is provided with a support pipe, so that the support pipe can receive mechanical power during internal / external turning and operation, in which case the guide pipe is arranged inside the support pipe. The cable or antenna extends into the guide pipe. The guide pipe ends inside the submarine, preferably just in front of the antenna guide portion fixed to the submarine, and the guide pipe is arranged in line with the antenna guide portion. In this case a part of the guide pipe at the exposed end of the support pipe is preferably supported inside the support pipe so as to be movable along an axis, and acts in the drawing direction between the part of the guide pipe and the support pipe. A spring, preferably a spiral spring, is arranged. This spring causes compressive stress to act in the antenna or cable at the restored position. When the withdrawal operation is performed again, the compressive stress is supported and acts on the starting process.

It is preferable that the support pipe is covered with a profile suitable for flow in order to have as little interference as possible on the submersible as well as the hydrodynamic properties of the submarine even with the antenna or cable pulled out. The profile suitable for flow may likewise be formed as a pipe, for example as a pipe with an elliptical cross section, or may be formed only with a lead profile located in front of the flow direction.

In order to prevent the device from being mechanically damaged by the pulled-out antenna or cable in case of excessive load, a separating device for both ends of the antenna or the cable is provided near the end of the guide part, especially the submarine side of the guide pipe. This separator is preferably controlled according to the tensile force acting on the cable, but if, for example, there is not enough time to insert the antenna or cable and it is more advantageous to cut the antenna or cable quickly, the device inside the submarine is also suitable. Can be cut.

In order to protect the guide and the mechanical and hydraulic parts and / or electrical parts co-operating with the guide part from external influences during normal driving, the entire device is installed in one housing, which is located inside the submarine's envelope. It is placed on one side and sealed by the outer shell. The closure of this housing is preferably made by one or more (including one) flap valves on the outer shell of the submarine, which flap valve is a bin for passing the guide section after self-rotating, in particular for turning the guide section. It is installed to provide enough space.

It is particularly preferred if the whole device is formed as an embedded module, ie installed as a replaceable functional unit including a housing. In this case, the device can be replaced quickly and simply in the event of a fault or when repair is required. Furthermore, in such a modular approach, such a device may be complementary to an existing submarine after making a corresponding recess in the enclosure.

In order to be able to withdraw virtually any number of antennas or cables in this way, a number of devices according to the invention can be arranged in submarines.

With reference to the embodiment shown in the drawings the present invention will be described in detail below.

The submarine shown in FIG. 1 consists of a submarine hull formed long in a conventional manner, the interior of the submarine hull being formed by a cylindrical pressure hull 2 (FIG. 2) wrapped with a shell 3, the shell (3) accommodates additional devices of the submarine in addition to the pressure hull (2) to provide a hydrodynamically advantageous shape for the entire submarine hull. An upper deck 4 is formed at the center of the submarine 1, a driving propeller 5 is provided at the stern, and a direction key 6 formed as an X-key is seen in front of the propeller in the flow direction.

The submarine 1 shown in FIG. 1 comprises devices 7 for pulling out the antenna 8 on the top side and devices 9 for pulling out the antenna on the bottom side. As the antenna 8, a floating antenna is handled, which is typically provided for GPS-, HF-, VHF-, UHF-, EHF- or SHF-antenna. In this case, a sensor device such as any other antenna or environmental sensor or SIG INT-antenna (EL INT = Electronic Intelligence, COM INT = Communication Intelligence, AC INT = Acoustic Intelligence, IM INT = Image Intelligence, OPT INT = Optical Intelligence SIG INT = Signal Intelligence) may be installed. The antenna or sensor in this case may be arranged at the end of the cable to be pulled out or may be formed of the cable itself as is known. As shown in FIG. 1, the floating antenna 8 is guided away from the shell 3 of the submarine 1 together with the devices 7 so that the antenna reaches inside the stern area, in particular the propeller 5. There is no danger of becoming.

With respect to the device 9 on the lower surface near the stern of the submarine 1, submarine acoustic antennas, ie floating antennas, are dealt with. In this case, alternatively, the devices induced by other floating antennas or locked antennas or cables can be withdrawn. The embodiment shown in FIGS. 1 and 3 should be understood as only one example.

The entire devices 7 or 9 shown in FIGS. 1 and 3 are shown in the operating position. That is, the guide portion of these devices is shown as being positioned to be pulled out through the shell 3 or to be rotated outward.

4 and 5 show the device 9 with the antenna 10 in detail. The device 9 can be installed on the upper surface of the submarine 1 in the same way to form the device 7 as shown in FIG. 1. Side mounting is also possible.

The device 9 comprises a sealed housing 11, in which all the fastenings and moving parts of the device 9 are in an inoperative position, ie in a position pivoted into the shell 3 of the submarine 1. It is accepting. The housing 11 forms not only a support for the device 9 but also a protection, but is not sealed in a sealed manner similar to the shell 3 of the submarine 1, but rather perfusion at the boundary. The housing 11 is integrated in a rectangular recess coinciding with the shell 3 so that it is firmly and permanently connected to the submarine 1. The device 9 integrated in the housing 11 in this case forms a unit which can be replaced in this area relatively simply by rolling off the shell. Since the housing 11 can be sealed from the outside by the pivotable flap valve 12, the device 9 is in the non-operational position (FIG. 4) and when the flap valve 12 is closed, the region In the sealed enclosure 3 is actually formed.

The guide part for the antenna 10 consists of the support pipe 13 which is not shown in figure, and this pipe gives a mechanical stability of the guide part. The support pipe 13 is surrounded by a profiling pipe 14 which is advantageous for flow, which allows the flow resistance and scratches to be as small as possible even when the support pipe 13 is fully pivoted. In the support pipe 13, a guide pipe 15 is arranged coaxially with respect to the pipe, and the antenna is moved in the pipe. The end of the guide pipe 15 is supported to be movable inside the support pipe 13. Between the end of the guiding pipe 15 and the supporting pipe 13 is arranged an axial spiral spring which actually presses down the guiding pipe 15 in FIG. 5, which spring of the guiding pipe 15 is arranged. The end is tightened with respect to the support pipe 13 and pressed outward. The spring not only causes the part of the guide pipe 15 to move by power toward the free end of the support pipe 13, but also takes care of the supporting action when the antenna 10 is pulled out.

A deflection roller 16 is rotatably arranged at the free end of the support pipe 13, and the antenna 10 is guided through the roller. As shown in FIG. 5, the deflection roller 16 is further covered by the profiling pipe 14 so that it lies in the area of the profiling pipe as it flows. In order to be able to carry out the change of direction, the deflection roller 16 may optionally be arranged pivotably about the axis of the guide, in particular the guide pipe 15.

The guide part of the device 9, consisting of a support pipe 13, a profiling pipe 14, a guide pipe 15 and a deflection roller 16, inside the housing 11, in particular about the pivot axis 17. It is arranged to be able to turn.

The support pipe 13 pivotally supported about the shaft 17 is firmly connected to the lever arm 18, the intermediate lever 19 is connected to the end of the arm, and the intermediate lever is pivoted again. One end of the lever 20 is articulated and the other end of the pivot lever is actuated by the piston rod 21 of the hydraulic cylinder 22. The pivot lever 20 is supported so that pivoting is possible about the pivot shaft 23. In the position where the piston rod 21 is inserted into the hydraulic cylinder 22 (FIG. 4), the guides 13, 14, 15, 16 are placed in the housing 11 inside the shell 3 of the submarine 1. . In order to pull out the guide part, the flap valve 12 is first operated by a hydraulic mechanism (detailed description is omitted), and then the hydraulic cylinder 22 is pressurized, whereby the piston rod 21 is pulled out. Thus, the pivot lever 20 is pivoted from the position shown in FIG. 4 to the position shown in FIG. 5 so that the guide portion is actually perpendicular to the shell 3 via the intermediate lever 19 and the lever arm 18. Is turning into. Because of the lever device when the piston rod 21 is completely pulled out, the piston rod is automatically in the outwardly rotated position, ie the lever device, because no restoring moment can be provided to the swinging arm 20 through the guide. It is locked by the automatic lock of. When the piston rod 21 is inserted, the guide part can be rotated again.

In the outwardly pivoted position (FIG. 5) the ends of the guide pipe 15 lying inside the housing 11 are arranged in a line at a slight distance and with respect to the guide pipe 24 fixed to the housing, The guide pipe 24 moves the antenna 10 to the device 9. The state for the guide part is shown by way of example in FIG. 2. In FIG. 2 a hoist 25 with its own antenna is arranged between the pressure hull 2 and the shell 3 at the top of the submarine hull, from which the antenna 10 is arranged via a deflection roller 26. It is supplied to (9).

A separation device 27 is provided in the region of the guide pipe 24 fixed to the housing, in which case the antenna 10 can no longer be inserted or should not be inserted, or if the tension from the antenna is to a predetermined degree. If exceeded, the antenna 10 may be cut by the separating device.

2 is described with reference to the angle α that the antenna 10 can take with respect to the horizontal line (the longitudinal axis of the submarine) without entering the propeller 5. Thus the angle α is also a measure of the submarine's maneuverability with the antenna pulled out.

With the present invention, antennas or cables in underwater boats, in particular submarines, can eliminate the disadvantages of the prior art and allow the submarine to withdraw multiple antennas from virtually any location without significantly affecting the hydrodynamic and acoustical properties of the submarine. It is now possible to manufacture a device for extracting the.
