Definitions

  • the invention relates to a submarine according to the features indicated in the preamble of claim 1.
  • submarines of larger design often have, in addition to the main shaft, which allows normal access to the pressure hull, another, so-called rescue shaft, which serves to allow the boat to leave the boat via a lock formed by the rescue shaft For example, the main shaft is blocked for whatever reason.
  • another, so-called rescue shaft which serves to allow the boat to leave the boat via a lock formed by the rescue shaft
  • the main shaft is blocked for whatever reason.
  • such an additional shaft can also serve for the inward and outward transfer of persons without having to block the main shaft for this purpose.
  • a problem with submarines of small and medium size is that such a rescue shaft, which, if it should be suitable for the insertion and removal of persons, usually must have a height of at least 2.5 meters to to be able to take an adult person, due to the size is not or can only be integrated with considerable disabilities within the pressure hull.
  • a tower-like structure for a rescue shaft is conceivable, but this alone is associated with considerable drawbacks for aerodynamic reasons, quite apart from the considerable design effort, which is why such a solution usually does not come into consideration.
  • the present invention seeks to provide a generic submarine with a telescopic shaft so that it can also be used in boat areas lesser height and space-saving and structurally simple in the submarine can be integrated.
  • the basic idea is to make the additional shaft, which can serve as a rescue shaft or for the inward or outward transfer of persons and / or objects, telescopic, ie form in the direction of its longitudinal axis with variable length. It is therefore a submarine with a pressure body and at least one shaft provided, wherein the shaft forms a lock between the interior of the pressure hull and the surrounding atmosphere and is formed telescopic.
  • This telescoping, ie length-variable design of the shaft has the advantage that the required for the lock function height, which claimed either inside the pressure hull considerable space and is a hindrance or leads to a projection outside of the pressure hull, only required, although the lock function is required. For this purpose, the shaft is then telescoped.
  • the lock function especially if this serves only as a rescue shaft, is practically never needed in normal operation, the space required for the rescue shaft can be significantly reduced, so that even in submarines small size can be integrated without the input described To have room problems.
  • the shaft Only in the case of the shaft is telescoped, ie extended to its full length, which is dimensioned so that, for example, a person on the shaft at least discharged advantageous but also can be introduced.
  • the telescoping length is not limited to the size of a human, the shaft may optionally also serve for the inward and outward transfer of objects such as small submarines, rescue capsules and the like and is then interpreted in terms of size.
  • the shaft may be one or more times telescopic, ie consist of two or more mutually longitudinally displaceable shaft sections, which lie in the inserted position into one another and connect in telescoped position to each other.
  • the shaft consists of a shaft section fixed to the boat and a further telescoping shaft section guided thereon, wherein the telescoping shaft section is arranged within the boat-fixed shaft section or is guided within the fixed shaft section.
  • the boat-fixed shaft portion is formed by an outer and an inner shaft portion, wherein the telescoping shaft portion between the outer and the inner shaft portion of the boat-fixed shaft section on or is movable.
  • This additional inner shaft part which is firmly connected to the outer shaft part, for example by screws or welding, serves essentially as a mounting platform for equipment such as ladders and other stationary to be mounted Components, as they are also provided for fixed shafts, whereas the outer shaft portion forms the supporting part of the outer shaft portion.
  • the shaft can be telescopically formed inwards or outwards or in both directions.
  • the shaft is at least partially, but preferably completely in the pressure body is telekopierbar.
  • the shaft is expediently arranged so that it is arranged in the retracted position substantially between the pressure body and outer skin in order to take up little space within the pressure hull, and in extended, d.
  • Telescoping position protrudes correspondingly far into the pressure body.
  • the telescoping inward in particular has constructive advantages, since the male intrinsic forces are comparatively low and the seal is less problematic than with a telescopability to the outside.
  • the shaft is arranged on the boat top, and preferably in a region of the pressure hull, which is pressure-tight against the region of the pressure hull, which is connected to the main shaft. This allows the division of the pressure hull into two mutually pressure-tight parts, which are accessible via a shaft, as is customary even in larger submarines, without the space otherwise required for a shaft space required for the other shaft.
  • the boat-fixed shaft section in particular the outer shaft part between the pressure hull and the outer skin arranged and fixed, this otherwise unusable space can be used in an advantageous manner for the additional shaft and the constructive measures required in this context without claiming at least in the retracted position unnecessarily free space within the pressure hull and the other without overhanging the outer skin or requiring projections in the outer skin, which could adversely affect the flow behavior of the boat.
  • the telescoping shaft section remains in the retracted position, in particular, and does not extend into the pressure body due to, for example, vibrations due to its own weight, it is expedient to make it lockable at least in the retracted position.
  • it may also be an interlock in extended, d. H. be provided telescoped position.
  • the telescoping shaft section at one end, in an arrangement in which it is telescopically inward, expediently at its upper end a flange, which preferably bears at both ends sealing rings, which are effective in the two end positions.
  • lip seals which are designed and arranged so that the sealing effect is pressure-assisted, d. h., That in the respective end position, then, for whatever reason, the interior of the shaft is subjected to the pressure of the environment, the lip seal works pressure-assisted, so as to reliably prevent ingress of water into the pressure body interior.
  • At least one lifting cylinder is preferably provided, which is effective at least in the retraction direction in the above-described construction variant in which the telescoping shaft section can be extended downwards into the pressure body.
  • the extension can then take place optionally by weight of the shaft section.
  • double-acting lifting cylinders typically hydraulically operated lifting cylinders used, expediently two relative to the shaft axis offset by 180 ° to each other to be able to specifically control in this way the retraction and extension of the telescopic shaft section and to prevent tilting.
  • the lifting cylinders are then mounted so far outside that within the shaft enough space remains for a person to be inserted or ejected therein.
  • the shaft at both ends with a lid, typically a hatch cover pressure-tight lockable.
  • the lids are pivotally hinged advantageous, namely about an axis transverse to the shaft axis and such that they each open in the outward direction, d. H. that the external pressure with closed lid acts in the closing direction.
  • the covers are expediently relieved of weight by spring preload or other suitable means, so that they can be opened and closed substantially force-free.
  • the inventive telescopic shaft can serve not only as a rescue shaft but also as a battery charging shaft and replace it. Also, in the case of an existing submarine in the course of retrofitting, for example, the battery charging shaft can be replaced by a telescopic shaft.
  • the shaft illustrated with reference to the figures can in principle be provided at any point of the submarine, typically replacing the otherwise existing battery charging shaft at the top of the submarine near the front or rear end.
  • a pressure body 1 of the submarine and an outer skin 2 are hinted. While the pressure body 1 forms the persons receiving pressure-resistant core of the submarine, the spaced-apart outer skin is provided substantially to form a streamlined outer contour of the boat. Between the pressure body 1 and outer skin 2 there are also other components, typically immersion cells, hydrogen storage, pipe connections and the like.
  • the shaft essentially consists of two shaft sections, namely a boat-fixed outer shaft section 3 and a telescopic shaft section 4 on the other hand.
  • the fixed shaft section 3 has an outer cylindrical shaft section 5, which is fixedly arranged between pressure hull 1 and outer skin 2 and is reinforced on the circumference by ribs 6 ,
  • the outer shaft part 5 is welded at the top to the outer skin 2 and connects below to a massive support and guide ring 7, which in a corresponding Recess in the pressure hull 1 and firmly connected to the pressure body 1 is connected.
  • a cover plate 8 is inserted, which closes the shaft upwards.
  • a cylindrical inner shaft part 9 is screw-mounted, which forms an inner fixed shaft wall and is used for foundation and attachment of equipment for rescue and for normal operation. This example, ladder, handles, actuators and the like are attached.
  • This shaft section 4 consists of a cylindrical tubular part 10, which springs back in its lower portion to the inside, so that a paragraph 11 results and is closed at the bottom by a bottom plate 12.
  • a flange-shaped integrally formed ring 13 connects, which is provided at its outer periphery with guide elements 14 which slide on the inside of the outer chess part 5 along.
  • two circumferential lip seals 15 and 16 are arranged in concentrically arranged grooves 17 and 18.
  • the lip seals 15 and 16 are each incorporated by means of fastening rings 19 and 20 form-fitting, which are connected by screws 21 to the ring 13.
  • the lip seals 15 and 16 thus fixed in the upper side of the ring 13 have sealing lips 22 which, in the upper end position shown in FIGS. 1 and 3, ie when the shaft section 4 is retracted, ensure that the shaft interior is opposite the outer shaft part 5 and thus also the pressure body 1 is sealed.
  • the lips 22 are, as Fig. 3 illustrates, arranged so that they with increasing internal pressure with increasing force to the underside of the cover plate 8 are pressed.
  • lug-shaped locking elements 23 are provided, which are screw-fastened to the underside of the support and guide ring 7 and uniform over the entire circumference of the support and guide ring 7 are arranged. These locking elements 23 have slots, so that after loosening the mounting screws they can be withdrawn. In the locking position, the locking elements 23 engage over the shoulder 11 and thus secure the shaft section 4 against extension.
  • the shaft section 4 can be extended by its own weight or pressure-force-assisted downward into the working position shown in Fig. 2.
  • two offset relative to the longitudinal axis 24 of the shaft by 180 ° arranged double-acting hydraulic cylinders 25 are provided, which extend or retract the shaft section 4 depending on the control.
  • the control of the hydraulic cylinder 25 takes place from outside the shaft, namely from inside the pressure hull 1.
  • a circumferential lip seal 26 is disposed in a groove 27 on the lower end face of the ring 13 and fixed in the same manner as at the top by a fastening ring 28 by means of screws 21 on the ring 13.
  • This lip seal 26 also has a sealing lip 22, which, however, is arranged (see FIG. 4) such that the pressure prevailing in the interior of the shaft in the telescoped position of the shaft assists the sealing action, ie. H. the sealing lip 22 presses against the upwardly facing end face in the shoulder of the support and guide ring.
  • a further seal 29 is provided concentric to the lip seal 26, which is arranged within a groove 30. The seal 29 also works pressure-assisted, since with increasing internal pressure in the shaft increases the force acting on the ring 13 downward force and thus the contact pressure of the seal 29 is amplified.
  • the shaft has on its upper side, ie inside the cover plate 8, a hatch 31 which can be closed by a hatch cover 32.
  • a hatch 33 is provided in the floor panel 12, which is also lockable by a hatch cover 32.
  • the hatch covers 32 are each pivotally mounted about an axis 34 which is arranged transversely to the longitudinal axis 24 of the shaft.
  • the hatch covers 32 are formed in a conventional manner and weight balanced by spring force, so that they are substantially neutral in weight pivoting.
  • line connections and fittings are provided which allow flooding and flooding of the shaft to at least as a rescue shaft to be able to eject persons from the pressure vessel interior in a submerged state.
  • the shaft can also be used to pick up divers or to inject and remove objects.
