Description

The present invention relates to a cable stock comprising a fastening portion for attachment to an object to be sheltered from the seabed for recovery thereof, a winding portion and a recovery portion having cable, the cable being disposed in the winding portion in a plurality of winding layers having an inner winding layer and an outer winding layer, and with first fixing means for fixing the recovery section and / or the winding section against the buoyancy, and with means for releasing the first fixing means.

The present invention also relates to a cable storage device for a fastener section for attachment to an object to be sheltered from the seabed for recovery, a cable having a winding section and a recovery section, the cable being disposed in the winding section in a plurality of winding layers having an inner winding layer and an outer winding layer wherein the fastening portion is connected to the inner winding layer, and wherein the cable is wound in the winding portion to form a, in particular rotationally symmetric, cable hollow body, with first fixing means for fixing the salvage portion and / or the winding portion against the buoyancy, and with means for releasing the first fixative.

Rope supplies of the aforementioned type so far consist essentially of wound on cable drums ropes, wherein after releasing the fixing elements, the cable drum with the winding section and the salvage section rises in the water upwards. In this case, the winding section is wound from the cable drum, whereby the salvage end reaches the water surface with a corresponding rope length and thus the salvage can be initiated thereupon.

A disadvantage of the cable stocks of the relevant state of the art is the following.

While rope stocks of the relevant state of the art ascend, loops and / or knots can form in the winding section.

On the other hand, prior art rope supplies are often subject to substantially irregular tumbling motion during unwinding of the rope. As a result, the formation of knots and loops in the winding section is aggravated disadvantageously.

The described formation of knots and / or loops has a negative effect on the tensile strength of the rope stocks. Thus, they can lead to fiber breaks, especially in high performance ropes made of synthetic fibers, as they are preferably used in the recovery of heavy objects. This reduces the achievable load of these ropes, which may possibly lead to the demolition of the object to be protected.

In addition, the described formation of loops and / or knots reduces the recovery length of the unwound winding section. Consequently, the salvage section may no longer reach the water surface. Accordingly, the recovery difficult, if not even made impossible.

The invention is therefore based on the object to provide a generic cable stock and a generic cable storage device to improve the reliability of salvage.

This object is achieved in terms of the generic cable supply by the mounting portion is connected to the inner winding layer. Characterized in that in this case takes place the development of the winding section from the inside to the outside, an outer guide of the inner winding layer is advantageously achieved by adjacent to the inner winding layer winding layers. This guide counteracts the formation of loops and / or nodes in the winding section, which can have a particularly positive effect on the development of the last winding layers in the winding section.

In a preferred embodiment of the cable stock according to the invention, the cable is wound in the winding section to form a, in particular rotationally symmetrical, cable hollow body. In contrast to, for example, a wound cable strand, the winding leads to a hollow cable body with advantage that the winding section has a directed against the collapse of the windings and the formation of loops and / or knots stability. In this case, since the winding section is also hollow, the winding section is suitable for unwinding from the inside to the outside. In addition, a winding section wound around the hollow body offers the advantage of storage and transport, for example, of a core element introduced into the hollow space of the hollow body, which can advantageously avoid entangling the winding section. The winding to, for example, a hollow cylinder advantageously ensures a continuous development of the cable stock, since the rotational symmetry transmits partly to windings of the winding section.

The cable supply according to the invention has a preferred embodiment, in which an inner circumferential surface of the inner winding layer is formed substantially cylindrical and / or conical. By the inner circumferential surface having such a shape, the cable supply can be stored and transported according to the invention on commercially available coils in the form of a cone or cylinder, which makes the use of Seilvorrates in this regard as particularly simple.

Furthermore, the cable supply can be designed according to the invention to the effect that the cable has a from the mounting portion to the inner winding layer extending bushing portion, which is arranged performed by the hollow wire body. This ensures that the development of the winding section takes place during buoyancy of the Seilvorrates from the seabed towards the water surface from below from the supply of ropes. In contrast to a corresponding development from above, the advantage in this embodiment according to the invention is that the cable avoids slipping along the edge formed by the outer winding layer. Therefore, the cable wear and a lateral force load of the winding portion, which can promote the looping and / or knot formation, can be avoided.

In the case of the supply of ropes according to the present invention, the rope in the winding section may have a twist for the benefit of unwinding. The twist gives the rope a certain flexural rigidity, which can counteract the collapse of windings under the influence of buoyancy forces, which is why the formation of loops and / or knots can be advantageously prevented.

The problem underlying the invention is achieved with regard to the generic cable storage device by providing a core element designed for insertion into the cable hollow body, with an outer lateral surface adapted to the inner lateral surface of the inner winding layer. Consequently, for example, a coil provided as a core element supports the winding section, so that translatory movements of the winding section can be restricted, whereby a displacement of the windings to each other can be counteracted advantageously avoiding looping and / or knotting.

A further preferred embodiment of the cable storage device according to the invention provides that second fixing means are provided for fixing the core element against the buoyancy. Accordingly, a provided as a core element coil, which may be provided according to the invention for the play-free mounting of the winding section, for example, be screwed to an object to be sheltered. By such a fixation, the core element remains on the object to be rescued after the first fixing means have been released. While an impelling core element is unsuitable for underwater storage of the winding section, the fixing according to the invention of a core element for underwater storage of the winding section is advantageous.

In a preferred embodiment of a cable storage device according to the invention, the core element is removably disposed under the influence of buoyancy forces downwardly from the winding section and the recovery section. Accordingly, in this embodiment, the winding portion and the salvage portion may rise to the water surface, while an exemplary coil for supporting the winding portion at the object to be salvaged remains under water. While such a coil provided as a core element positively influences the transport and storage of the cable stock, its whereabouts in the recovery section and winding section would be unfavorable for the settlement or could even make the settlement impossible. Thus, it could get caught in the rope, which may be contrary to the intended avoidance of knots and / or loops. Consequently, the removability of the core element according to the invention is advantageous.

A cable storage device according to the invention may be designed such that the core element has a guide groove for guiding the passage section. If the core element is designed, for example, as a cylindrical coil, the guide groove according to the invention can consist of a longitudinal groove in this coil. The longitudinal groove can also simplify the professional installation of the cable in the cable storage device, so that tilting of the downwardly coming from above implementation section of the rope with the inner circumferential surface of the winding section is prevented.

The longitudinal groove also prevents accidental unwinding of the rope from the inside. If the lead-through section were led out of the winding section without a longitudinal groove, then it would be easy to unwind the winding section. The core would make this even more difficult, but it would be possible.

Through the groove, the diameter of the core can be adjusted. The end of the rope above with passage through the groove completely prevents unintentional unwinding.

If the rope is guided in the fastening section in such a groove, it is in this section secured against loop and / or knot formation, which is correspondingly advantageous to the development of the winding section transmits.

Furthermore, a cable storage device according to the invention can be configured such that a winding sleeve radially surrounding the outer winding section is provided. A winding sleeve according to the invention can for example consist of a cassette with a wall which can stabilize the outer layer of the winding section, for example, against ocean currents.

At the same time, this cassette also constitutes an assembly aid for the cable in the cable storage device. To stabilize the winding section, the cassette can also be configured as a film in which the winding section of the cable is welded. The core is freely removable.

A preferred embodiment of the cable storage device of the invention provides that a Wicklungsmitnehmer is provided to transmit to the winding portion of the winding force generated by the winding portion amount exceeding or corresponding thereto buoyant force. A winding cam according to the invention may, for example, consist of a self-propelling disc with an opening for the fastening section, on which the winding section and the recovery section rest in the direction of the buoyancy forces. The buoyancy of such a disc according to the invention stabilizes the buoyancy of the winding section and the recovery section in the direction of the buoyancy forces from below, so that the cohesion of the winding section is supported, which can advantageously avoid the formation of loops and / or knots.

In a preferred embodiment of the cable storage device according to the invention, a buoyancy body operatively connected to the salvage section is provided. A buoyant body in the context of this invention can support the buoyancy of the winding section and the recovery section to the water surface, or even allow only when the own buoyancy of the rope for carrying the salvage section to the water surface is insufficient. The recovery section can be achieved with the buoyancy body according to the invention by a node in the recovery section with a hook in the buoyancy body. In order to realize a buoyancy from a great depth of the sea of several hundred meters or more, the buoyancy body in the context of the invention may comprise syntactic foams.

Furthermore, the buoyancy body can be provided in a further development of the invention with locating elements, whereby the finding of the cable storage device is facilitated. The locating elements can be configured as radio direction finders, bulbs, or GPS transmitters

Finally, the cable storage device according to the invention can be designed so that it comprises a cable supply according to one of claims 1 to 5. In this embodiment, the winding portion of the cable supply is wound around the core element of the cable storage device according to the invention. In this case, a part of the cable storage direction with the winding section and the recovery section of the cable can rise from the cable supply, while the core element of the cable storage device remains on the object to be sheltered.

The cable storage device according to the invention may, for example, additionally comprise a disc ring, the edge of which supports the winding section of the cable supply. The edge of this disc ring can be designed so that this edge also entrains the winding section during the buoyancy of the cable storage device. The opening of the disc ring may guide the attachment portion to the object to be rescued.

Functionally identical parts are provided with the same reference numerals.
