Rescue system for the rescue of crew members of a ship

Background of the Invention The present invention relates to a rescue system for rescuing

Crew members of a ship, with a closed escape pod for receiving the crew members.

Rescue systems are used on both civilian and military vessels to rescue crew members in an emergency from the ship, for example, in those cases where the ship threatens to sink. To accommodate the crew members rescue devices, such. B. open lifeboats or inflatable

Liferafts are used. From DE 33 04 495 A1 a rescue system is known in which instead of an open rescue boat a closed rescue capsule for holding the

Crew members is provided in an emergency. The rescue capsule can over a

Slide from the ship to be drained into the water. The rescue capsule offers the crew a good protection against weather effects and effects of water z. B. due to a brief submersion below the water surface or due to wave.

In this rescue system, it has proved to be disadvantageous that the

Rescue capsule is stored on a weather deck, so a deck that has neither a roof nor is otherwise protected against weather. Therefore, damage to the escape pod and the components required to deploy the escape pod due to wind and weather can not be excluded. In the military field of application, z. As in warships, usually liferafts are used, which are distributed over the weather decks of the ship. These liferafts are particularly vulnerable to the action of bullets and / or splinters. There is therefore a risk that the life rafts will be disabled, so that a rescue of the crew members is not possible. DISCLOSURE OF THE INVENTION The object of the present invention is to improve the availability of the escape pod.

In a rescue system of the type mentioned, the object is achieved in that the rescue capsule is arranged in an entry position in which the rescue capsule is mountable by the crew members, in a closed shelter of the ship.

The arrangement of the rescue capsule within the shelter, the

Crew members board the escape pod in an area protected from the weather and / or the effects of combat, so that the crew members are protected from these influences. In addition, the rescue capsule is stored protected from weather conditions and / or combat action, so that even with long-term storage of the rescue capsule in the shelter no damage due to external influences are to be feared. This can increase the availability of the escape pod.

Preferably, the rescue capsule can be moved from the entry position into a driving position, in which the rescue capsule is movable in the water independently of the shelter and / or the ship. An advantageous embodiment provides that the shelter can be closed by a closure element, which by an unlocking device from the inside of the

Rescue capsule is unlocked out, so that a safe opening of the

Closure element is also possible when the shelter is at least partially below the water surface. The closure element is preferably designed as a hatch, via which a hatch opening can be closed. The hatch can be waterproof. Particularly preferably, the unlocking device is designed as a mechanical unlocking device. The unlocking device may comprise a handle, for example a crank, which can be coupled to the closure element for unlocking the closure element and can be separated from the closure element after unlocking. It is advantageous if the handle after unlocking the closure element can be completely spent in the interior of the rescue capsule. It is particularly advantageous if the closure element is detachable from the shelter. By loosening the closure element, an opening of the shelter can be released, so that the escape pod can be discharged through the opening of the shelter. Preferably, the closure element is completely out of the opening of the

Shelter removable. Particularly preferably, the closure element is detachable such that it can fall off the ship.

It is preferred that the shelter has a valve, via which water can be introduced into the shelter. In such cases, where the shelter is located below the water surface, by introducing water into the shelter, the pressure within the shelter may be equalized to the pressure present outside the shelter. In this way, the opening of the shelter, in particular the release of the protective element can be facilitated. According to an advantageous embodiment, the rescue system has a

Acceleration device, through which the escape pod can be accelerated out of the shelter. About the accelerator, the rescue capsule, especially in your direction of travel, are set in motion. It is thus possible to quickly remove the rescue capsule in an emergency from the shelter, which may be particularly advantageous when the ship is under attack. It is not necessary to use a crane z. B. in the ceiling area of the shelter to deploy the rescue capsule, whereby the shelter can be made more compact overall. Preferably, the acceleration device is designed as a catapult device, so that the rescue capsule can be catapulted out of the protective space.

In this context, it has proved to be advantageous if the

Acceleration device has a traction means for accelerating the escape pod out of the shelter. About the traction device, the rescue capsule from the

Shelter be pulled out. The traction means may be formed, for example, as a pull rope, as a pull wire or pull chain.

Preferably, the acceleration of the rescue capsule is adjustable, so that the

Acceleration depending on the flooding state of the shelter can be selected. Particularly preferably, the acceleration is adjustable so that the rescue capsule can be deployed with a greater acceleration, provided that the

Shelter is located above the water surface and can be carried out with a smaller acceleration when the shelter is below the water surface, so that overstressing the accelerating device, in particular the

Zugmittels, due to a higher resistance of the water can be avoided.

Furthermore, it has proved to be advantageous if the rescue capsule in the

Entry position in a dispensing direction, along which the rescue capsule from the shelter is ausbringbar linearly movably received in a receptacle, so that the rescue capsule can be applied directly from the entry position of the shelter. Preferably, the dispensing direction coincides with the direction of travel of the rescue capsule, so that the rescue capsule can continue to move in the same direction after being brought out of the shelter. The receptacle can be designed in the manner of a linear guide. A preferred embodiment of such a receptacle has a plurality of rollers on which the rescue capsule rests in the entry position. Particularly preferably, the receptacle has a plurality of two opposite walls of the

Shelter arranged roles, so that the rescue capsule is received in the entry position between the rollers. The escape pod may be linearly movable in a direction perpendicular to the axis of rotation of the rollers.

It is also advantageous if the rescue capsule is received in the entry position in such a way that it is secured against movement transversely to the Ausbringrichtung, so that damage to the rescue capsule by collisions with the

Walls of the shelter can be avoided. Preferably, the rescue capsule is secured in the entry position against floating, so that even with the ingress of water into the shelter damage to the rescue capsule is not to be feared. Preferably, the receptacle stops to prevent movement of the

Rescue capsule in a direction transverse to the deployment direction. In a receptacle having rollers, it is advantageous if the receptacle has stops which prevent movement of the rescue capsule parallel to the axis of rotation of the rollers. The

Stops can be designed as components separate from the rollers. It is particularly preferred if the stops are integrally formed on the rollers, resulting in a particularly compact design. It is advantageous if the stops together with the rollers form a linear guide.

The rescue device preferably has a damping device for damping shock effects on the rescue capsule in the entry position. About the

Damping device vibration of the rescue capsule can be reduced as a result of the action of shock waves and prevents damage to the rescue capsule become. Particularly preferably, the damping device has damping elements, via which the receptacle of the rescue capsule is mounted in the shelter. In a recording, the rollers, a plurality of rollers are preferably arranged in a holder which is connected via damping elements to the shelter.

It is advantageous if the shelter is designed as a replaceable module, so that a ship mission specific can be equipped with the rescue system. Furthermore, it is possible in a trained as a module shelter to replace the shelter after the application of the escape pod against an unused shelter with rescue capsule. The module may be designed in the manner of a transport container. Preferably, the module is detachably arrangeable on a ship.

It is particularly advantageous if the shelter is armored, so that the protection of the escape pod is increased before the action of projectiles. The shelter may have a ballistic self-closing structure and / or be formed of armored steel. It is preferred if the protective space is pressure-tight and / or watertight and / or gas-tight.

An advantageous embodiment provides that the rescue capsule has a particular electric drive, so that the rescue capsule is driven driven after the discharge from the shelter in the water. To feed the drive, the rescue capsule preferably has a battery and / or a solar cell.

Embodiments of the invention

In the various figures, the same parts are always provided with the same reference numerals and are therefore usually named or mentioned only once in each case.

FIGS. 1 to 3 show a first exemplary embodiment of a rescue system 100 according to the invention, which can be used on civilian as well as on military vessels 1 in order to rescue crew members in the event of an emergency of the ship 1.

The rescue system 100 includes a closed rescue pod 150 in which crew members may be admitted in an emergency. In order to prevent damage to the rescue capsule 150 due to weather or Geschosseinwirkungen, the rescue capsule 150 is in a boarding position in which the

Crew members can get on board the rescue capsule 150, arranged in a closed shelter 101 of the ship.

The shelter 101 is in the interior of the ship 1, i. in the area below one

Weather decks of the ship 1 arranged. The shelter 101 is formed as a module 102, which can optionally be provided or exchanged on the ship. In this respect, it is possible to remove an already used or defective module 102 from the ship 1 and to exchange it for a functional module 102. In such ships 1, which can carry several modules 102, an on-demand number of modules 102 can be carried on the ship 1. For example, the number of modules 102 may be adjusted to the number of crew members.

The outer skin of the shelter 101 is formed by side walls 103, a ceiling 104, a bottom 105, a rear wall 106, and a shutter 121. The side walls 103, the ceiling 104, the bottom 105, the rear wall 106 and the closure element 121 are preferably designed ballistically protected, for example, that they consist of a steel armor. The trained as a module 102 shelter 101 has a ballistic self-closing structure. In addition, the module 102 is pressure tight and waterproof educated. As a result of these measures, the rescue capsule 150 mounted within the protective space 101 can be protected against damage caused by external influences.

The rescue capsule 150 is disposed within the shelter 101 in a receptacle 1 10. The receptacle 10 includes two receiving parts arranged on the side walls 103. The rescue capsule 150 is connected only via the receptacle 1 10 with the shelter 101. There is no direct connection between the escape pod 150 and the floor 105 or the ceiling 104 of the shelter. In this respect, the rescue capsule 150 is suspended within the shelter 101. The receptacle 1 10 has a plurality of rollers 1 12, the axes of rotation substantially vertical, d. H. perpendicular to the bottom 105 of the shelter 101, are arranged. By the rollers 1 12 it is possible that the rescue capsule 150 is received linearly movable in the receptacle 1 10. The linear movement of the rescue capsule 150 can take place in a discharge direction R. In the dispensing direction R, the rescue capsule 150 can be deployed out of the shelter 101 into the water.

The rescue system 100 further has the special feature that the rescue capsule 150 is received in the entry position 150 in the receptacle 10 in such a way that it is secured against movement transversely to the delivery direction R. The backup is achieved in that on the recording 1 10 stops 1 15, 1 16 are provided, the one

Movement of the rescue capsule 150 in the vertical direction, d. H. in a direction substantially perpendicular to the bottom direction prevent. The stops 1 15, 1 16 are arranged in the embodiment of FIG. 1 -3 to the rollers 1 12. Preferably, the stops are integrally formed with the rollers 1 12. Alternatively, the stops 1 15, 1 16 may be provided as separate, separated from the rollers 1 12 elements. A lower stop 1 16 is disposed below the roller 1 12 and an upper stop above the roller 1 12. The rescue capsule 150 has a projection 156, which is preferably formed circumferentially around the outer contour of the rescue capsule 150. The projection 156 may be formed in the manner of a bead. In the entry position of the rescue capsule 150, the projection 156 between the stops 1 15, 1 16 is arranged. Preferably, the projection 156 is in the entry position in contact with a, in particular the lower, stop 1 16 or with both stops 1 15, 1 16. Insofern form the

Stops 1 15, 1 16 together with the rollers 1 12 a linear guide, in which the rescue capsule 150, is guided. Secured by the transversely to the discharge direction R

Arrangement of the rescue capsule in the receptacle 1 10 can movements of the

Rescue capsule 150 can be prevented in the vertical direction. In particular, can be prevented be that the rescue capsule 150 floats when water enters the shelter 101.

As can be seen from Figures 1 and 3, the rollers 1 12 of the receptacle 1 10 in the region of the side walls 103 of the shelter 101 are arranged side by side. On a side wall 103, a rail 1 1 is provided in each case, in which a plurality of rollers 1 12 are mounted. In the first embodiment, the rails 1 1 1 over

Damping elements 1 14 coupled to the side wall 103 and / or with the ceiling 104 and / or the bottom 105. In this respect, the damping elements 1 14 form a

Damping device 1 13 for damping vibrations of the rescue capsule 150 in the entry position. By the damping elements 1 14, the rescue capsule 150 can be protected from damage by the action of shock waves.

The rescue capsule 150 is designed in the manner of a closed, watertight and / or gastight and / or pressure-tight capsule. In this respect, the rescue capsule 150 is submersible. The outer contour of the rescue capsule 150 is streamlined. Inside the rescue capsule 150 a crew room 151 is provided, in which several crew members can be accommodated. The outer skin of the

Rescue capsule 150 has a plurality of windows 152 through which the crew members can perceive the environment of the rescue capsule 150. The rescue capsule 150 is designed in the manner of a self-sufficient rescue device. On board the rescue capsule 150, an electric drive, in particular an electric motor, is provided, which is fed from an electrical system. To the electrical system solar cells and / or a battery are connected. The energy required to operate the drive can be provided during the day by the solar cells and at night by the battery.

The rescue capsule 150 is stored in the entry position in the direction of travel R, i. the bow of the rescue capsule 150 is directed towards the closure element 121 of the shelter 101 and the stern towards the rear wall 106 of the shelter 101. in the

Rear area of the rescue capsule 150, an access hatch 151 is provided, via which the crew members can climb the rescue capsule 150 in the entry position. The escape pod 150 is disposed within the shelter 101 such that the

Entrance hatch 151 with a arranged on the rear wall 106 of the shelter 101 hatch 107 is aligned. The crew members can pass from the interior of the ship 1 through the hatch 107 in the rear wall 106 of the shelter 101 and the access hatch 155 of the escape pod 150 into the crew compartment 151 of the rescue pod 150. Before the escape capsule 150 can be deployed out of the shelter 101, the closure element 121 closing the protection space 101 must first be unlocked and opened. The closure member 121 closes an opening 120 of the

Shelter 101. As can be seen from FIG. 4, the closure element 121 is designed in the manner of a hatch, which is aligned with the outer contour of the ship 1. The

Closure element 121 has a viewing port formed as a porthole 122, through which the crew members from the rescue capsule 150 out the environment of the ship can observe. This can be advantageous if it is to be determined whether there closure element 121 above the water surface or partially or

completely located below the water surface. The closure element 121 is locked by means of closures 5 designed as sash fastener closures. The locking of the

Closure element 121 can be unlocked from inside the rescue capsule 150, in particular from the crew compartment 151. To unlock the

Closure element 121 is a mechanical unlocking device 123 is provided. The unlocking device 123 has a shaft 124, is connected to a locking element 127 which cooperates with the closures 5. The shaft 124 can be actuated via a handle 125 of the unlocking device 123 arranged in the crew compartment 151 of the rescue capsule 150 and designed as a crank. To the

Unlocking the closure element 121, the handle 125 is coupled to the closure element. By turning the handle 125, the shaft 124 can be rotated. As a result of the rotation of the shaft 124, the locking member 127 is rotated and the shutters 5 unlocked. The shaft 124 is releasably coupled to the locking member 127 so that the handle 125 after unlocking can be pulled together with the shaft 124 into the interior of the rescue capsule 150. The released by pulling opening 157 in the outer contour of the rescue capsule 150 is closed by a sealing element 126, such as a sealing screw.

The unlocked closure element 121 can be released from the shelter 101. The closure element 121 is designed as a separate component, so that it can be completely removed from the region of the opening 120 of the protective space 101. In a situation in which the shelter on unlocking the closure member 121 above the

Water surface W is arranged, the closure member 121 may fall by the action of gravity in the water. If the closure member 121 should not disengage from the opening 120, it will be pushed away from the rescue capsule 150 as the escape capsule 150 is deployed through the opening 120. In a situation where the shelter 101 is at least partially located below the water surface W, the closure member 121 may be carried away from the water. To allow the release of the closure element 121 then, when the

Shelter 101 is at least partially below the water surface W, the shelter 101 has a valve, via which water can be introduced into the shelter 101. By introducing water before unlocking the

Closure element 121, the water pressure on both sides of the

Closing element 121 can be compensated. Thus, it can be prevented that the closure element 121 is pressed by the water pressure applied from the outside to the edge of the opening 120 and can not be detached from the shelter 101.

For discharging the escape capsule 150 from the shelter 101, a catapult device is configured within the shelter 101

Accelerator 130 is provided, which is shown in Figure 5. About the accelerator 130, the rescue capsule 150 from the receptacle 1 10 of the shelter 101 through the opening 120 of the shelter 1 10 can be accelerated. The acceleration of the rescue capsule 150 takes place in the direction of travel of

Rescue capsule 150, so that a direct transition from the spreading movement is made possible in the driving movement. The escape pod 150 can therefore move away from the ship 1 without having to make any change in the direction of acceleration after deployment.

The accelerator device 130 has a pull cable 131, via which an in

Dispensing direction R acting tensile force on the rescue capsule 150 can be applied. The traction cable 131 engages in the region of the rear of the rescue capsule 150 at the

Rescue capsule 150 on. To connect the pull cable 131, a projection is provided on the rescue capsule 150, in which a loop of the pull cable 131 engages. The pulling cable 131 is guided over a first deflecting roller 132 arranged in the region of the opening 120, in particular on the bottom 105. From the first deflection roller 132, the pulling cable 131 extends over a second deflection roller 133, which is arranged in the region of a side wall 103, in particular on the base 105. The pull cable 131 extends over a pulley 135 to a fixed point 134 within the shelter 101, to which the pull cable 131 is firmly connected. A part of the pulley 135 is linearly movable in a linear guide 136

arranged so that upon actuation of a coupled to the pulley cylinder 137, a tensile force is applied to the pull cable 131. Due to the tensile force absorbed in the receptacle 1 10 rescue capsule 150 is linearly accelerated. The actuation of the cylinder 137 can take place from the rescue capsule 150, in particular from the crew room 151. Upon actuation, a trigger valve 139 is opened, so that in one Compressed air tank 140 flow of air through the trigger valve 139 into an accumulator 138 and can actuate the 137 cylinders.

The acceleration device 130 is designed such that the acceleration applied to the escape capsule 150 is adjustable. In the accelerating device 130, two trigger valves 139 are provided, which allow a different speed release of the stored air in the compressed air tank 140 and can be selectively operated. The acceleration may be set such that the escape pod 150 is deployed at a greater acceleration when the shelter 101 is above the water surface W. By choosing a smaller one

Acceleration provided that the shelter 101 is located below the water surface W, overstressing the hauling rope 131 of the

Accelerator 130, be avoided due to a higher resistance of the water. With the described acceleration device 130, it is thus possible to deploy the escape capsule 150 either above or below the water surface W. The crew members can contact each other before pressing the

Accelerator 130 inform if the shelter 101 is below or above the water surface W. For this purpose, the crew members can look through the windows 152 of the escape pod 150 and the porthole 122 of the closure member 121. Alternatively or additionally, a pressure measuring device, in particular a pressure gauge, can be arranged on the outer skin of the protective space 101, for example on the closure element 121, which can measure the external pressure and whose measured value can be provided to the crew members within the rescue capsule 150. The

Crew members sitting in the rescue capsule 150 preferably in Ausbringrichtung R.

Is the shelter 101 above the water surface W is the

Rescue capsule 150 accelerated by the accelerator 130 linearly in the discharge direction R through the opening 120. The rescue capsule 150 is first passed through the receptacle 1 10 and then falls after leaving the receptacle 1 10 in free fall towards the water surface W. In such cases, in which the shelter 101 is below the water surface W, the rescue capsule 150 is linear accelerates out of the receptacle 1 10 and then floats in the direction of water surface W. In the figures 6 to 8 is a second embodiment of an inventive

Rescue system 100. In contrast to the first exemplary example, the shelter 101 according to the second embodiment is not designed as a module but in the Structure of the ship 1 integrated. The floor 105 and the ceiling 104 are formed by decks 3 of the ship 1. The side walls 103 and the rear wall 106 are connected to the decks 3 of the ship 1. Further, in the second embodiment, no

Damping provided. The receptacle 1 10 is, in particular the rails 1 1 1 of the receptacle 1 10, rigidly connected to the side walls 103 of the shelter 101.

The rescue system 100 according to the second embodiment is suitable

especially for civilian ships where protection against the effects of shockwaves is not required. In the event of a pirate attack, the crew of the ship 1 may enter the escape pod 150 unnoticed and leave the ship 1 quickly without any activity being visible on the free decks of the ship 1. In the best case, the pirates then have to decide whether they want to continue to focus on the ship 1 or the crew in the rescue capsule 150. The above-described rescue systems 100 for rescuing

Crew members of a ship 1 have a closed rescue capsule 150 for accommodating the crew members, which is arranged in an entry position in which the rescue capsule 150 is mountable by the crew members in a closed shelter 101 of the ship 1. As a result, the rescue capsule 150 can be protected against external influences and thus the availability of the rescue capsule 150 can be increased.
