Definitions

  • the invention relates to a submarine.
  • Submarines with an independent propulsion system can operate in arctic waters over an extended period of time under a sealed ice cover.
  • a sealed ice cover Under dive trips under a confined ice cover, such emergency situations prove fatal, requiring inmates to leave the submarine. In such a situation, the ice cap prevents these people from reaching the top of the ice.
  • the invention has for its object to provide a submarine that makes the occupants at dive below a closed ice cover an exit from the submarine to above the ice cover possible.
  • the basic idea of the invention is to equip a submarine with an upward boring device, which is arranged in a pressure body of the submarine and has a drill which can be extended from an opening of the pressure body arranged on the upper deck side, wherein a drill head of the drill has a closure body closing the opening of the pressure hull forms.
  • a drilling device is possible to dive below a closed Ice cover from underneath into this one hole and most beneficial to drill an exit hole for the crew of the submarine. Through this exit hole, the occupants can leave the submarine, for example, in an emergency situation and get to above the ice cover.
  • the drilling device is positioned on or in the submarine so that when the submarine is directly below the ice cover, a drill located outside the hull can attach to and puncture the underside of the ice cover.
  • the drill is expediently dimensioned so that it can be used to create a borehole whose cross section or diameter allows persons to pass through here.
  • the drill has a drill head whose diameter is at least equal to or greater than the diameter of an exit opening arranged on the submarine on the submarine.
  • the drill head may be similar to the drill heads used in tunnel boring machines and have a plurality of cutting edges on a substantially flat end side next to a centering point arranged in its center.
  • drilling heads can be provided with a conical tip having a plurality of extending from the center of the drill head to its outer periphery cutting.
  • the drilling device is arranged in the pressure hull of the submarine and the drill of the drilling device can advantageously be extended from a top-deck-side opening of the submarine.
  • the drilling device is expediently arranged directly below such an opening of the pressure body or in such a position directly below the opening of the pressure body movable.
  • the drill bit of the drilling apparatus is advantageously oriented such that it can be extended out of the opening normal to the opening plane.
  • the opening formed on the pressure body is pressure-tight to close.
  • the drill head of the drill forms a closing body closing the opening of the pressure body. Accordingly, the drill head of the drill is not positioned when the drilling device is positioned such that the opening formed on the pressure body closes pressure-tight.
  • an embodiment is advantageous in which the drill head has a larger diameter relative to a shank of the drill, at the end of which the drill head is arranged, and thus forms on the drill a radially projecting annular shoulder relative to the shank.
  • the drill can rest on the outside of the pressure hull at the edge of the opening formed there and thus close the opening pressure-tight.
  • the shank of the drill is arranged in a rotatable by a rotary drive driven hollow shaft and coupled in movement with the hollow shaft.
  • a hollow shaft is preferably arranged in the pressure body below an opening formed on the upper side of the pressure body, into which the shaft of the drill engages.
  • the hollow shaft may directly form the drive shaft of a drive motor or it may, as is preferably provided, via a transmission with the drive shaft of a arranged next to the hollow shaft drive motor, which is preferably an electric motor, be operatively connected.
  • the hollow shaft of the shank of the drill is connected at least in the direction of rotation of the hollow shaft with this form-fitting manner.
  • the drill can be directly coupled to a rotational drive of the drilling device. In this case, however, it is necessary to produce a linear feed movement of the drill, to move the drill together with the rotary drive in the direction of the ice cover to be drilled.
  • the rotary drive of the drill is fixedly arranged in the pressure hull of the submarine and a feed movement of the drill is possible independently of the rotary drive.
  • the drill is advantageously displaceable in the hollow shaft in the longitudinal direction. That is, the shank of the drill is guided linearly movable in the hollow shaft. At the same time, however, a rotary motion coupling with the hollow shaft is required.
  • At least one parallel to a longitudinal axis of the drill extending groove may be formed on the outer circumference of the shaft into which engages at least one formed on the inside of the hollow shaft projection or there fixedly arranged sliding block.
  • a secure torque transmission to the outer circumference of the shaft diametrically spaced from each other two aligned in the longitudinal direction of the drill grooves formed, in each of which an engaged on the inner circumference of the hollow shaft corresponding to the grooves of the shaft Gleitstein intervened.
  • the length of the groove or grooves formed on the shaft determines the possible feed path of the drill.
  • the drill is preferably pressurizable on a side facing away from the drill head with a pressure medium.
  • a pressure medium for example, at the end remote from the drill head of the shank of the drill a telescoping pneumatic or hydraulic cylinder attack.
  • form the drill and the hollow shaft itself can be acted upon with a pressure medium pressure cylinder.
  • forms the hollow shaft expediently a part of a pressure chamber of the printing cylinder.
  • This pressure chamber is preferably filled with seawater as the pressure medium. This seawater can be pumped from the outside environment of the submarine into the pressure chamber via a conduit leading from the outside environment of the submarine into the pressure chamber.
  • the submarine When drilling an exit hole through an ice cover, the submarine is conveniently located directly at its top on the underside of the ice sheet.
  • deformation bodies are advantageously arranged in the submarine according to the invention on its upper-side outer side. These deformation bodies form a crumple zone or yielding buffer between the submarine and the ice cover.
  • a deformation body for example, elastic, filled with water sacks and deformable tube racks can be used.
  • Fender as a deformation body is possible.
  • the submarine advantageously extendable anchoring devices for anchoring the submarine to the ice cover are provided on the upper deck side of the hull.
  • the anchoring devices are arranged on the submarine preferably at two diametrically opposite sides of the opening of the pressure hull, through which the drill is extended, spaced from each other in the longitudinal direction of the submarine. They can advantageously each have a plurality of tips which penetrate into the ice cover during the extension of the anchoring devices and thus fix the submarine to the ice cover in a form-fitting manner.
  • the anchoring devices are preferably formed hydraulically movable.
  • the submarine After having drilled an exit hole in the ice cover with the drilling device and retrieve the drill back into the submarine, the submarine is to be moved to a position where there is an exit opening of the submarine directly below the drilled exit hole.
  • the submarine can expediently have an auxiliary drive, for example in the form of at least one inline thruster. If the submarine is in the position where the exit opening of the submarine is below the drilled exit hole, a cover which otherwise closes the exit opening is opened.
  • an exit channel forming inflatable pressure hose In order to prevent in this situation that seawater flows over the now open exit opening into the submarine.
  • This pressure hose is initially folded to save space folded before use and is inflated before opening the lid of the exit opening, whereby it expands in the direction of its central axis until it then extends from the edge of the exit opening through the ice cover to above the ice cover. In this state, the pressure hose seals off the exit opening with respect to the seawater located on the outside of the pressure hose.
  • the drill forms an exit lock from the submarine.
  • the use of the drill as an exit gate is advantageous in that the submarine does not move after piercing the ice sheet to create an exit hole must be because the exit lock for leaving the submarine is already directly below the formed on the ice cover exit hole.
  • the shank of the drill is hollow and can be closed pressure-tight at its two ends, each with a removable closure.
  • access to the shaft can advantageously serve the pressure chamber located under the shaft.
  • this expediently has an access opening which can be closed pressure-tight with a closure.
  • the inner diameter of the shank of the drill is typically sized so that a person can get into the cavity formed in the shank.
  • a climbing aid for example a preferably telescopic ladder, may advantageously be arranged in the shank.
  • the drill head of the drill forms an outer cover as an exit lock. Accordingly, the drill head can be removed from the shaft.
  • Both in the Fig. 1 and 2 pictured submarine as well as the in Fig. 3 shown submarine are in a diving position below an ice cover 2. Both submarines have a pressure body 4. At an upper side of the pressure body 4 of the submarines, which also forms an upper deck of the submarine in question, deformation bodies 8 are arranged. With these deformation bodies 8, the submarines abut the underside of the ice cover 2, the deformation bodies 8 forming a deformable crumple zone between the ice cover 2 and the submarines.
  • an opening 10 is formed in both submarines. Substantially directly below this opening 10 is within the pressure hull 4 at the in the Fig. 1 and 2 shown submarine a drilling device 12 and in the in Fig. 3 shown submarine a drilling device 12 'arranged.
