Definitions

  • the present invention relates to a watercraft having at least one buoyancy space in which a dispenser is arranged for dispensing a foam in a form unstable state, with a pressure line system for a pressure medium, which connects a first pressure generator and at least one dispenser, and with a control device, which first pressure generator and controls the at least one dispensing device in response to an emergency signal for dispensing the dimensionally unstable foam, wherein the form unstable foam passes after dispensing from the at least one dispensing device in a dimensionally stable state of aggregation.
  • Such a watercraft is off, for example EP 1 104 384 B1 known.
  • the watercraft described in this document is a passenger ship in which there is a plurality of buoyancy chambers. In the buoyancy chambers there is a dispenser for a dimensionally unstable foam.
  • the discharge devices of the individual buoyancy chambers are connected to one another via a pressure line system.
  • the pressure line system is connected to a pressure generator.
  • the pressure generator generates a pressure in the presence of an emergency signal, so that pressure gas present in the pressure line system and a control device for dispensing the dimensionally unstable foam lead from the respective dispensing device.
  • buoyancy chambers can be filled with foam after triggering the emergency signal.
  • buoyancy volume is conserved, so that a sinking of the passenger ship is prevented due to a higher stability of the leak.
  • the object of the present invention is therefore to develop a watercraft of the type mentioned in such a way that a leakage stability also broken apart Sharing a ship is achieved.
  • a second pressure generator is provided and the pressure line system extends between the first and second pressure generator, wherein in the pressure line system a plurality of dispensing means are provided, between which at least one check valve in the flow path of the pressure medium is arranged.
  • An advantage of the watercraft according to the invention is that now also broken apart parts of a ship or other watercraft can be formed leak-resistant.
  • the arrangement of a further pressure generator and the installation of check valves can be maintained in the broken parts of a ship closed portions of the pressure line system, so that in the buoyancy chambers of the broken parts of a ship from the dispensers foam can be delivered in form unstable state, then to Transfer into a dimensionally stable state of aggregation passes. In this way, the broken parts of a ship can be saved from sinking.
  • Another advantage of the present invention is that the dispensers in the pressure line system are parallel to each other and the check valves are arranged in series. By this arrangement, the pressure line system is optimized.
  • each dispenser is associated with a buoyancy space. This means that in a buoyancy space, a plurality of dispensing devices may be present, but it would be disadvantageous if a dispenser would be assigned to several buoyancy spaces.
  • first pressure generator on the bow side and the second pressure generator are arranged on the rear side. In this way, the leakage stability can be optimally ensured in the present frequent case of breaking into two parts, in both parts.
  • the pressure line system comprises a loop and a plurality of stubs, each drop being installed in a stub.
  • first and second pressure generator are connected to each other via the ring line and each dispenser basically can be pressurized by both pressure generators.
  • the check valves can be controlled so that certain Dispensing devices can only be pressurized by the first pressure generator and other specific dispensing devices only from the second pressure generator.
  • each check valve is installed in the loop between two stubs. By this arrangement, the control of the check valves for dividing the pressure line system can be done easily.
  • Fig. 1 is schematically shown from above a watercraft 1.
  • the watercraft 1 has a bow 3 and a stern 5 in the present embodiment.
  • a fuselage 7 extends between the bow 3 and the stern 5.
  • the plan view also shows a pressure line system 9.
  • the pressure line system 9 comprises a first pressure generator 11 and a second pressure generator 13, wherein the first pressure generator 11 on the bow side and the second pressure generator 13 is arranged on the rear side.
  • a pressure line 15 extends.
  • Fig. 2 is a plan of the watercraft 1 off Fig. 1 represented with a pressure line system of the prior art.
  • a pressure line system comprises a (first) pressure generator, which is arranged centrally and from which in each case a pressure line in the direction of the bow and in the direction of the rear.
  • Fig. 3 the pressure line system 9 is shown schematically in greater detail.
  • a loop 15.1 extends with a in Fig. 3 illustrated flow direction from the first pressure generator 11 to the second pressure generator 13 on the left side (see arrow) and a flow direction from the second pressure generator 13 to the first pressure generator 11 on the right side.
  • the number of branch lines 17 depends on the distance between the first pressure generator 11 and the second pressure generator 13 and on the number of buoyancy spaces 19.
  • a dispenser 21 is installed, which is associated with a buoyancy chamber 19.
  • Several dispensing devices 21 may be associated with a buoyancy chamber 19. This is not essential to the present invention.
  • the design of the dispenser 21 is not essential to the invention. In practice, the dispenser will form a nozzle or a number of nozzles from which foam may be dispensed in a dimensionally unstable state.
  • the dispenser either comprises a storage tank (not shown) or is connected to a storage tank (not shown).
  • a storage container for a foam in the form of an unstable state of aggregation is integrated in the delivery device 21.
  • a check valve 23 is arranged between two discharge devices 21, a check valve 23 is arranged.
  • the check valve is installed in the loop 15.1.
  • Such a check valve 23 may be installed between two adjacent dispensers 21 or between non-adjacent but proximate dispensers.
  • a check valve 23 is installed between two adjacent discharge devices 21, that is, between two stubs 17.
  • the discharge devices are incorporated in parallel to each other in the pressure line system 9, while the check valves 23 are installed in the pressure line system 9 in series.
  • the pressure generated by the first pressure generator 11 and the second pressure generator 13 in the pressure line system 9 is directed to the dispensers 21.
  • the check valves 23 are open so that pressure from both pressure generators 11, 13 can reach the dispensers 21. But if such an emergency occurs that the watercraft breaks apart 1, then closes the check valve 23, which receives no back pressure due to the interruption of the pressure line system 9. In this way, the pressure line system 9 is divided, so that then the respective part of the broken-apart watercraft 1 only has a part of the pressure line system 9, which is then supplied either by the first pressure generator 11 and by the second pressure generator 13.
  • the pressure generators in the present embodiment are preferably pressurized gas generators and each have a capacity sufficient to pressurize all the dispensers.
  • a control device (not shown) which controls the first pressure generator 11, the second pressure generator 13 and the discharge means 21 and the check valves 23 in response to an emergency signal.
  • a control device comprises a power source, a computer, a wiring and possibly sensors.
  • An emergency signal is an electrical signal.
  • Such an emergency signal can be triggered automatically when sensors detect a leak, or triggered manually when such a leak is visually perceived.
  • the control device it is possible with the control device to close only very specific check valves toconcentr2020en only certain buoyancy chambers 19 depending on the location of the leak. So it can be foamed single or all buoyancy chambers. After the delivery of a dimensionally unstable foam from the dispenser 21, the latter goes into a dimensionally stable state of aggregation in the corresponding buoyancy chamber 19. In the dimensionally stable state of matter, the foam has a large, closed pore volume.
  • the pressure line system 9 is preferably mounted in the vessel 1 in a grid-like structure as shown in FIG Fig. 3 is shown.
