Definitions

  • the present invention relates to an elongate hollow body, in particular a hose, according to the preamble of patent claim 1 and a device for sound insulation under water with such an elongated hollow body according to claim 14.
  • the disadvantage here is that a considerable noise emission can occur, which can be disturbing or even dangerous for aquatic organisms, in particular whales and seals.
  • the disadvantage here is that the line cross-section can be reduced by the introduced body such as chains, ropes or the like and thus the flow rate can be less than a hose of the same nominal size without additional weightings in the hose.
  • Another way to increase the overall weight of the hose is to add extra weights to the outside of the hose.
  • This can e.g. Metal sleeves, chains or steel cables.
  • a disadvantage in this case is that the assembly of the weighting body on the outside of the line can be very labor-intensive. In addition, there is a risk that foreign objects get caught in the attachments during operation and, if necessary, can be brought on board the floating units or land. Furthermore, the attachments such as Hooked chains and ropes in the area and the line can not be recovered or only with increased effort. Eventually threatens total loss.
  • the EN 20 2016 104 155 U1 describes a device for sound insulation for piling under water, wherein the device at least one fixable on the seabed line having a plurality of holes, and at least one compressor with which compressed air in the line can be introduced so that it can escape from the holes , having.
  • the conduit has at least one longitudinal section in the form of a hose.
  • the tube has a layered wall construction which, from the inside to the outside, comprises an inner layer, a first reinforcement layer, an intermediate layer, a second reinforcement layer and an outer layer, wherein at least one weighting body and at least one spring wire spiral are embedded in the intermediate layer.
  • the spring wire spiral is arranged so as to extend spirally in a longitudinal direction of the hose.
  • the advantage is seen that the outer shape of the conduit remains unchanged, so that it can be easily and / or introduced, as is well known in the art.
  • the line can easily be wound up or unwound on a winding device with a drum.
  • the spring wire spiral serves as a kink protection when winding or unwinding the line, but holds on the other hand, the shape of the hose at positive or negative pressure stable.
  • the disadvantage here is that the weighting body and the spring wire spirals occupy almost the entire surface of the intermediate layer. Therefore, the holes can be set as outlets of compressed air only at those points of the hose, which are not occupied in the intermediate layer by weighting elements or spring wire spirals. This can severely limit the number, size and location of the holes. Furthermore, the accidental attachment of holes at locations which are occupied by weighting elements or spring wire spirals can lead to damage of the weighting bodies and / or the spring wire spirals. In particular, a spring wire spiral can be severed, so that the spring wire spiral can lose its function at least at this point of the hose. However, this may be sufficient to allow a kink at this point and thus damage the entire hose.
  • An object of the present invention is to provide an elongate hollow body, in particular a hose, of the type described above, so that the disadvantages described above can be reduced or avoided.
  • an elongated hollow body, in particular a hose is to be provided, so that holes for the passage of e.g. Compressed air can be positioned from inside to outside with a greater freedom and / or designed as previously known.
  • the surfaces of the elongated hollow body, in particular of the hose are to be increased, at which holes can be provided.
  • the holes should be provided with larger dimensions and or or in greater numbers than previously known. All this should be made possible without damaging or destroying a weighting body and / or a spring wire spiral by the introduction of the holes.
  • the present invention relates to an elongated hollow body, in particular a hose, for arrangement within a medium, in particular for placement on and / or above a ground under water.
  • an elongated hollow body extends much longer in its longitudinal direction than in the other directions.
  • Such an elongate hollow body may be used in particular for the delivery of media such as e.g. Air, especially compressed air, but also water, oil, fuel, bulk material, concrete, etc. are used.
  • media such as e.g. Air, especially compressed air, but also water, oil, fuel, bulk material, concrete, etc. are used.
  • such an elongate hollow body can be used to produce a bubble curtain by means of compressed air under water.
  • such an elongated hollow body can also be used for other purposes such as the conduction of a medium under water.
  • Underwater can mean that the elongated hollow body at least partially or completely in the water can be suspended or at least partially or completely arranged on the bottom of the water. Both sections are possible offset in
  • the elongate hollow body has an inner layer and an outer layer.
  • the inner layer encloses a volume, so that in this (internal) volume, the medium can be passed.
  • the outer layer is facing away from the (inner) volume and facing the environment of the elongated hollow body.
  • the elongated hollow body has at least one weighting body, which is arranged between the inner layer and the outer layer.
  • the weighting body is designed in such a way that the weighting body can keep the elongated hollow body under water to the desired extent while observing the boundary conditions of the application.
  • the elongated hollow body may have a total weight of about 17.5 kg / m with a positive buoyancy of about 13.5 kg / m, so that the elongated hollow body with a force corresponding to a resulting weight of about 4 kg / m can be kept underwater on a ground.
  • the elongated hollow body is characterized in that the weighting body is formed helically.
  • the helical weighting body designed as a lead wire and preferably as a double-wound lead wire.
  • the weighting body in addition to its previously described function of increasing the weight of the elongated hollow body can also take over the function of a spring wire spiral or a similar element, which serves as kink protection during winding or unwinding of the elongated hollow body and to stabilize the shape of the elongated hollow body can serve at positive or negative pressure.
  • the two functions can be combined in one element, so that it is possible to dispense with a separate spring wire spiral or the like.
  • an elongated hollow body such as in the EN 20 2016 104 155 U1 can be produced with less effort and / or at lower cost in terms of material and / or working time.
  • Another advantage is that the areas of the wall of the elongated hollow body, which are free of bodies, can be increased or increased. In this way, holes which penetrate all layers of the conversion of the elongated hollow body, can be arranged at more positions than in an elongated hollow body such as the EN 20 2016 104 155 U1 which can only have very limited possibilities for such holes. Also, the number of holes can be increased. Furthermore, more freedom in the design and / or in the dimensioning of the holes can be created.
  • the elongated hollow body has a plurality of bores which penetrate the layers in such a way that a medium, in particular a gas, can escape from the interior of the elongated hollow body to the outside, or the other way around.
  • a medium in particular a gas
  • at least the said inner layer and outer layer are penetrated by the bores in such a way that the bores can guide a medium through them.
  • further layers such as an intermediate layer and / or a reinforcement layer or several reinforcement layers, are present, they too are permeated by the respective bore.
  • an elongate hollow body according to the invention can be used, for example, to produce a bubble curtain by means of compressed air under water.
  • the elongate hollow body has an intermediate layer which is arranged between the inner layer and the outer layer, wherein the helical weighting body is arranged within the intermediate layer. In this way, a permanent and stable arrangement of the helical weighting body in the wall of the elongated hollow body can take place.
  • the inner layer and / or the outer layer and / or the intermediate layer comprises an elastomeric material, preferably consists of an elastomeric material, wherein the elastomeric material preferably air-resistant and / or weather-resistant and / or seawater resistant is.
  • the elastomeric material is a styrene-butadiene rubber (SBR).
  • SBR styrene-butadiene rubber
  • the inner layer and / or the outer layer comprises a plastic material or metal, preferably consists of a plastic material or of metal. In this way, a corresponding dimensionally stable elongated hollow body can be created.
  • the helical weighting body comprises metal, preferably made of metal. Because metals one can have comparatively high specific gravity, in this way the weight of the elongated hollow body can be increased more than at the same time its volume, which would increase by the displacement of the corresponding amount of water again the positive buoyancy and thus counteract the weight.
  • metals one can have comparatively high specific gravity, in this way the weight of the elongated hollow body can be increased more than at the same time its volume, which would increase by the displacement of the corresponding amount of water again the positive buoyancy and thus counteract the weight.
  • lead or a lead alloy may be used which has a comparatively high specific gravity over other metals.
  • the helical weighting body at least in sections, preferably completely, has a cylindrical cross section or a rectangular cross section. Both cross sections can also be easily manufactured over longer lengths, which can keep the manufacturing costs of the helical weight body low.
  • both cross-sections between the inner layer and the outer layer of the elongated hollow body can be arranged without increasing the thickness of the wall and thus the volume of the elongated hollow body too much. By minimizing the thickness of the wall, the displaced by the elongated hollow body volume of water and thus its positive buoyancy can be kept as low as previously described.
  • the elongated hollow body has a plurality of helical weighting bodies, which are arranged uniformly or non-uniformly offset from one another.
  • helical weighting bodies Preferably, two to eight helical weighting bodies are used. In this way, in the case of elongate hollow bodies, for most of the applications described above, sufficient weighting can be achieved with at the same time the lowest possible volume of the elongated hollow body and a high stabilizing effect of a helix.
  • the elongate hollow body has a plurality of short-part weighting bodies, which are arranged between the inner layer and the outer layer, preferably within an intermediate layer.
  • These short-part weighting bodies differ from the helical weighting body in that the short-weighted weighting bodies For example, as balls, chunks or wire sections have no significant expansion in the longitudinal direction of the elongated hollow body and no shape, which could have a stabilizing effect of a helix or spiral. Rather, the short-part weighting body primarily serve the pure increase in the weight of the elongated hollow body. It is advantageous here that the short-part weighting bodies can form sections of the wall and in particular of the intermediate layer, so that the weight of the elongated hollow body can be increased without increasing its volume.
  • the bores are offset relative to the helical weighting body. In this way it can be ensured that the helical weighting body is not damaged by the holes or by the introduction of the holes.
  • the elongate hollow body has at least one strength support layer, which is arranged between the inner layer and the outer layer.
  • the reinforcement layer is preferably a steel wire mesh.
  • the reinforcement layer may act to stabilize the elongated hollow body from the inside as well as from a stiffening against forces that can act on the elongated hollow body from the outside.
  • the elongated hollow body has at least two reinforcement layers which are arranged between the inner layer and the outer layer, wherein the helical weighting body is arranged between the two reinforcement layers.
  • the reinforcement layers are preferably steel wire mesh.
  • the reinforcement layer (s) comprise a textile material or metal, preferably consisting of a textile material or of metal.
  • the respective material properties can be used.
  • the present invention also relates to an underwater soundproofing device comprising at least one compressor for providing pressurized air and having at least one elongated hollow body, in particular a hose, as described above for directing the compressed air from the compressor under the water.
  • the elongated hollow body has a plurality of bores which penetrate the layers in such a way that the compressed air can pass from the interior of the elongate hollow body out into the water.
  • an inventive elongate hollow body can be used in the context of a device which can be used to produce a bubble curtain by means of compressed air under water.
  • Fig. 1 shows a schematic sectional view through the wall of an elongated hollow body 1 according to the invention according to a first embodiment.
  • the elongated hollow body 1 in this case is a hose 1, which is cylindrical and in its longitudinal direction significantly longer than in its radial direction, which is perpendicular to the longitudinal direction is formed. Accordingly, the representation of the Fig. 1 a section of an expanded cross-section through the tube 1, ie a cross-section that has been separated and spread.
  • the wall of the tube 1 has, from inside to outside, an inner layer 10, a first reinforcement layer 11, an intermediate layer 12, a second reinforcement layer 13 and an outer layer 14.
  • the inner layer 10, the intermediate layer 12 and the outer layer 14 are formed of an elastomeric material, namely a styrene-butadiene rubber (SBR).
  • SBR styrene-butadiene rubber
  • the two reinforcement layers 11, 13 each consist of a steel wire mesh.
  • a plurality of helical weighting bodies 15 are arranged, which run spirally in the longitudinal direction of the tube 1.
  • the helical weighting bodies 15 are each formed as a double-wound lead wire.
  • the individual helical weighting bodies 15 are uniformly spaced from one another in the circumferential direction of the hose 1, so that between the two adjacent helical weighting bodies 15, intermediate spaces 12 are formed within the intermediate layer 12, which spaces are free of weighting bodies 15.
  • a plurality of holes 16 are arranged, which connect the interior of the hose 1 with the environment such that air and in particular compressed air from the inside through the holes 16 can pass through to the outside.
  • at most one bore 16 is provided per gap in the circumferential direction.
  • the holes 16 are arranged such that the air can rise as directly as possible upwards.
  • At least the area of the circumference of the hose 1 which, when laid, is to the bottom of the water, e.g. aligned to the seabed, free of holes 16. In this way, an inventive hose 1 can be used to produce a bubble curtain by means of compressed air under water.
  • these intermediate spaces can be formed comparatively wide, since the helical weighting body 15 can take over at the same time the function of a spring wire spiral by their helical or spiral shape, so that can be dispensed with this as a separate component with appropriate space. This creates significantly larger spaces between the adjacent helical weighting bodies 15, which can be used for the arrangement of the holes 16.
  • Fig. 2 shows a schematic sectional view through the wall of an elongated hollow body 1 according to the invention according to a second embodiment.
  • additional short-part weighting body 17 are arranged in the intermediate layer 12. These serve to further increase the weight of the tube 1 without simultaneously increasing its volume and thus the positive buoyancy.
