Definitions

  • the invention relates to a device and a method for underwater rescue.
  • For the evacuation and rescue of people from damaged submarines there are a number of procedures that are executable depending on the depth.
  • For rescue from great depths for example, corresponding rescue dive boats or rescue bells are used. Disadvantage is that these must first be brought to the place of the accident. However, this time is not always given.
  • the escape can take place directly in a rescue suit or with a life jacket without the use of a sluice, which is up to a maximum depth of about 50 m.
  • an exit using a sluice application ie the crew is evacuated by single or double sluices from the boat.
  • a rescue suit provides for a buoyancy and thus allows a quick ascent, on the other hand, the breathing air required in this time is provided.
  • the buoyancy generated in this case is about 500 N.
  • this high buoyancy leads during the lock process to considerable difficulties in the fixation of the or the descendants and there is a risk that the people can not hold in each place and thus in the lock float. This in turn can lead to clogging of the lock and probably to the death of the persons. This effect is intensified by people becoming unconscious during the lock.
  • the high ambient pressure leads to a desaturation of nitrogen in the blood when leaving at greater depths.
  • the amount of dissolved nitrogen in the blood depends on the depth of immersion and the residence time. As it ascends to the surface of the water, the nitrogen reverts to the gas phase and, depending on the amount of nitrogen, can lead to diving disease.
  • a rescue suit with a rise hood is known.
  • a submarine rescue arrangement with a waterproof suit is known, wherein the suit has an integrally attached container in which a deployable life raft is stored and from which the life raft can be removed for deployment.
  • a rescue suit for submarine riders with an inflatable lift chamber, a rise hood and a hose with a free end for connection to a supply of a breathing gas is known.
  • a submarine rescue suit with a connection means is known.
  • the submarine rescue suit can be connected to a Atemnotluftstrom a submarine.
  • a submarine with at least one emergency exit lock is known, wherein in the emergency exit lock a holding device is arranged on the boat side holding means for releasable attachment to a submarine rescue suit, wherein a control device is provided for the automatic release of the holding means.
  • the object of the invention is to make the underwater rescue easier, safer and faster, so as to minimize the residence time of a person at high ambient pressure and thus the risk of the occurrence of diving disease and on the other hand to ensure a secure fixation of the person in the lock.
  • the coupling device serves for coupling an underwater rescue suit to a submarine.
  • the coupling device provides a mechanical connection as well as a connection to the supply of breathing air between the Underwater rescue suit and the sluice in the submarine ago, wherein when releasing the coupling device, the mechanical connection and the connection to the supply of breathing air are simultaneously solvable.
  • the mechanical connection serves to fix the person.
  • the mechanical connection serves to absorb the buoyancy force created by the underwater rescue suit. This allows the person to be held and secured in place via the securing means of the mechanical connection of the underwater rescue suit.
  • the mechanical connection may be a force-transmitting connection between the coupling device and the underwater rescue suit, in addition to the connection for supplying the respiratory air, wherein the mechanical connection and the connection for supplying the respiratory air are jointly and simultaneously releasable by the coupling device.
  • Advantage of the coupling device according to the invention is that the functions of the breathing air supply and the fixation of the person in the lock are combined with each other in the present system. Both compounds can thus be separated simultaneously. As a result, the stay of the person can be reduced under high pressure, since not two separate connections must be solved. In addition, in such a situation, additional steps pose an enormous risk because people in such an emergency situation do not always act rationally.
  • the coupling device is preferably designed as a quick coupling.
  • the quick coupling on two rounded and / or ergonomically shaped handles for triggering the quick release.
  • the principle of a quick coupling can be found, for example, US 2014/143986.
  • the quick coupling can be designed so that it is engaged without actuation, that produces a firm connection. This has the advantage that the arms and hands of the person are free and thus can work or even unconscious persons can be discharged.
  • the quick coupling so be configured that this solves the connection without operation.
  • the person must actively keep the clutch closed, but unconscious persons can not be excluded.
  • the mechanical connection is made to a belt integrated in the underwater rescue suit.
  • the mechanical connection must compensate for the increasing buoyancy of the underwater rescue suit of up to 500 N during the process.
  • a belt for example a hip belt, is advantageous.
  • the coupling device is automatically released.
  • the manual operation of the coupling device is simple and easy to use even in a massive system failure. This assumes, however, that the person is still operational.
  • an automatic triggering is advantageous.
  • both a pneumatic and, alternatively, a hydraulic release mechanism have proved to be particularly advantageous.
  • a mechanical release is also possible and does not depend on the functionality of the pneumatic or hydraulic system.
  • the automation also allows optimal time utilization.
  • the mechanical connection between the coupling device and the underwater rescue suit is made by means of a snap hook which is hooked into a fixture which is on the part of the coupling device which remains on the underwater rescue suit after separation of the coupling device.
  • the mechanical connection is made by means of a device surrounding the connection to the supply of breathing air.
  • a hose for the connection to the supply of breathing air on the outside of a reinforced tissue or network which is able to absorb the comparatively high forces of typically at least 500 N.
  • the invention relates to a submarine having at least one first arranged in a lock area coupling device according to the invention and arranged on the top of the lock area hatch, wherein on the hatch a triggering device for the automatic release of the first coupling device is arranged.
  • This combination is particularly advantageous for automatic removal.
  • the lock area must be flooded and the pressure equalization carried out before the hatch cover can be opened. Only then may the coupling device be released, so that the air supply and the fixation of the descending is guaranteed as long as possible.
  • the submarine has at least one first coupling device and one second coupling device in the lock area.
  • the time-critical process steps in the emergency exit via a sluice are usually the flooding and Lenzen the lock.
  • the overall evacuation process can be accelerated rapidly.
  • an unconscious person can be supported by another person.
  • the number of people to be escorted per procedure is limited both by the functional processes of the emergency exit via a sluice and the resulting physical strain of the exiting and by the spatial design of the lock area, the lock area can usually accommodate only one or two people. With large locks more people can be evacuated at the same time.
  • the submarine has at least one first delay circuit, wherein the first delay circuit is designed to delay the automatic release of the first coupling device. If the coupling device is still released during the opening of the hatch cover, there is a risk that the person can beat the hatch cover by the comparatively high buoyancy with a comparatively large force. This can lead to injuries and unconsciousness. To avoid this, a delay circuit can be used be provided, which ensures that the hatch cover is already fully open and is not maintained unnecessarily long on the other side. This allows the optimal timing of the evacuation.
  • the submarine has at least one second delay circuit, wherein the second delay circuit is designed to delay the automatic release of the second clutch device after the automatic release of the first clutch direction.
  • the second delay circuit triggers the other coupling devices in chronological succession and delayed.
  • the advantage of this embodiment is that the persons leave the lock area at a short time offset.
  • the delay is chosen so that the second coupling device is triggered immediately when the first person could have passed the hatch area. Due to the time delay, these persons do not hinder each other. This is particularly important because the people are usually back to back, as they are connected via the coupling device to the submarine and are therefore regularly aligned frontally to the wall. Automation also ensures that the second person does not wait longer than necessary.
  • the delay circuit can detect the passage of the hatch area by the first person by means of sensors and then triggers the second coupling device.
  • the sensors can be arranged in the hatch area and can be, for example, light barriers or non-contact near-field sensors.
  • the submarine has a first delay circuit and a second delay circuit.
  • the delay circuits are designed pneumatically. Advantage of this embodiment is that only works with air pressure. Compressed air is regularly available even in a damaged submarine, as it can be stored locally. However, electrical or hydraulic systems are more susceptible here, especially in the event of a failure of the central power supply. A mechanical delay circuit is also possible and not dependent on the functionality of the pneumatic or hydraulic system.
  • the coupling device is removably arranged in the lock area.
  • the lock area is usually comparatively cramped and is normally required for personnel and material transfers. Therefore, it is advantageous if the coupling device is placed in the lock area only in an emergency.
  • the coupling device can be connected for example by means of a quick coupling with the breathing air supply.
  • a communication device for example a pushbutton or a connection for a communication device, for example a plug connection for a headphone and a microphone is provided on the coupling, so that a communication between the exit person and the crew remaining in the submarine can be established.
  • a connection for a communication device may preferably be provided that this connection when releasing the coupling device, the mechanical connection and the connection to the supply of breathing air is simultaneously solvable.
  • the invention relates to a method of underwater rescue from a submarine, the method comprising the following method steps:
  • the method comprises the following method steps:

From the socket 30 is a mechanical connection 40 (retention function) and a connection to the supply of breathing air 50 for underwater rescue suit of the person 20.
  • the hatch cover 14 is initially closed, the tower 12 filled with air.
  • Fig. 3 is a cross section through a Schleusel2 a submarine 10 is shown, wherein there are two coupling devices in the lock 12.
  • the socket 30 of the coupling device has an automatic release 60.
  • the coupling device could also be triggered manually.
  • the two automatic releases 60 are interconnected via a triggering system 70, in which case the triggering system 70 operates pneumatically.
