Definitions
- the present invention relates to a network for bodies of water for catching, collecting and / or retrieving flat structures, in particular those made of open-cell foam plastic and which are soaked with contamination substances, on or from the surface of the body of water, according to the preamble of claim 1.
- Known nets for the sea and possibly also for inland waters are ideal for fishing under water.
- Such so-called positioning nets are designed either as rigid or flexible nets, with a lowering line under water and an adapted buoyancy line on the water surface, so that this positioning network is positioned essentially vertically in the water.
- Rigid nets are similar to a wall in the water and almost do not move when the sea is rough, so that the waves slosh over the net.
- Flexible gillnets move up and down with the waves when the sea is rough, but large or high waves will spill over the network here as well.
- the object of the present invention is therefore to create a network of the type mentioned, which can be pulled through the water in a tensioned manner similar to a control net, but which can move up and down with the sea in such a way that it is also at high seas and thus high waves with an upper area always remains above the water or wave surface.
- the features specified in claim 1 are provided in a network for waters to intercept, collect and / or obtain flat structures of the type mentioned at the outset.
- the measures according to the invention ensure that the network, with its flexible power supply unit, is always at a certain height above the surface of the body of water, even when there is considerable swell on the water.
- the design of the network results in an approximately tunnel-shaped arrangement of the network in water, the base walls of which are upright in the water and the arcuate intermediate area is located above the surface of the water and projects above it at a certain distance. Since the flexible power pack only offers a small surface for the wind and the waves, it is avoided that the curved area of the net is pushed over by the waves. Even if this arcuate area is deformed by the waves, a sufficient partial area still remains above the wave surface, which means that this arcuate area is hardly washed over by the waves.
- the network described so far consists of an actuating power supply and the flexible power supply connected to it, which, due to the design of its free longitudinal edge, is erected in an arc above the water surface with lowering and buoyancy elements. It could be that this cross-section-like shape of the net below and above the water surface does not withstand all conceivable conditions in the sea, such as hurricane-like storms.
- the features are provided according to claim 10, which also prevent the network as a whole from being able to position itself in a largely flat state in the body of water.
- the features are advantageously provided according to claim 11, so that there is a symmetrical positioning of the network in the water and above the surface of the water.
- This embodiment with the variant mentioned also has the advantage that the desired position of the network in the body of water is maintained even if water pressure builds up on the network from both outer sides, so that only the clear width between the opposing longitudinal edges of the flexible Power supply or the two control power supplies is changed.
- the features according to claim 13 are provided. So that settles Net due to the flexibility of the flexible power supply, as soon as it comes out of the water, flat, the two actuating power supplies either positioned approximately parallel to the flexible power supply or only slightly sagging.
- the flexible power pack is designed in accordance with the features of claim 14.
- a limp network design used in fishing technology can be used, which can be designed with simple means to a power supply that can be bent in the corresponding direction.
- the features according to claim 15 and / or 16 are expediently provided.
- Such flexible solid or hollow rods made of different profiles, such as round tube, rectangular tube, etc., are made of plastic, glass fiber or glass fiber, carbon fiber reinforced plastics or the like. manufacture.
- a further significant simplification of the production of the network is obtained if the features are provided according to claim 20.
- the present invention also relates to a method for removing contamination layers using one or more of the aforementioned networks.
- the features according to claim 25 are provided.
- FIG. 1 shows a schematic cross-sectional representation of a network for bodies of water according to a first exemplary embodiment of the present invention, in the state floating in the water,
- FIG. 2 shows a schematic, fragmentary perspective illustration of the network according to FIG. 1 in a flat initial state that can be wound up
- FIG. 3 shows schematic sectional representations of networks according to FIG. 1 in different operating states in a body of water
- FIG. 4 shows a schematic illustration of a device for deploying nets according to FIG. 1, characters
- FIG. 6 shows a further exemplary embodiment of one or more designed networks according to FIG. 1,
- FIG. 7 shows a schematic, cross-sectional illustration of a network for bodies of water according to a second exemplary embodiment of the present invention, in the floating state
- FIGS. 8A-8B show a partial plan view and a side view according to arrow IIB of FIG. 2A the network outside the water and in a windable state outside a water and
- FIG. 9 in comparison to the cross-sectional shape of FIG. 1, shows the shape of a network floating in the water in a simplified schematic illustration with considerable cross-pressure application through the water.
- the network 10, 110 shown in the drawing according to two exemplary embodiments of the present invention is intended for bodies of water 12, 112 and here in particular for the seas and is used to intercept, collect and / or retrieve flat structures 11, 111, in particular made of open-cell foam plastic, such as open-pore foam PP or PU or PE soft foam that soaks up with contamination substances, such as oily layers, for example oil rugs, oil films, or such as liquid plastic layers, for example styrene films, or the like when removing such contamination layers from the surface of the water.
- open-cell foam plastic such as open-pore foam PP or PU or PE soft foam that soaks up with contamination substances, such as oily layers, for example oil rugs, oil films, or such as liquid plastic layers, for example styrene films, or the like when removing such contamination layers from the surface of the water.
- the network 10 has a control network 13 made of rigid or flexible material and an associated additional power supply in the form of a grid 14, which consists of flexible, in particular transverse elastic material.
- the control net 13, which is constructed from a simple network layer 16, has at its one free longitudinal end 17 a lowering line 18 made of or with lead-containing material.
- a lowering line 18 made of or with lead-containing material.
- two mutually parallel lift lines 21 and 22 are provided, between which a traction rope 23 runs in the longitudinal direction and which floats in the area of the water surface 15.
- the only network layer 16 of the control network 13 merges into a network layer 26 of the grid network 14 or is integral therewith.
- the grid 14 is provided with two further network layers 27 and 28 which lie on the network layer 26 and are connected to the latter.
- the other network layers 27 and 28 are laid in one piece and meandering. It goes without saying that the net layers 26 to 28 as a whole can also be laid in one piece and meandering.
- the grid 14 is provided with a buoyancy line unit 33 which, for example, consists of three individual buoyancy lines and which floats in the region of the water surface 15.
- the distance between this lift line unit 33 and the lower line 32 of the lattice network 14 is substantially smaller than its distance from the lift lines 21, 22 in the connection area 19 from Grid 14 and gusset 13.
- the gauze 14 has further individual buoyancy lines 36, which are preferably arranged at a uniform distance from one another and which are longitudinal an arcuate course of the grid 14 protrude from the water 12.
- FIG. 2 shows the configuration or the flat state of the network 10 constructed from the actuating network 13 and the grid network 14, in which state the network 10 can be wound up on a drum and, according to the illustration in FIG. 4, can be unwound from this drum 41 by a ship 40 and onto it Waters 12 can be brought.
- the network 10 When the network 10 is laid out according to FIG. 4, it goes from its initially flat state according to FIG. 2 to a tunnel-like state according to FIG. 1, as can also be seen from FIG.
- This change in state results from the arrangement of the lower lines 18 and 32 and lift lines 21, 22 and 33, which cause the positioning network 13 and the region 34 of the lattice network 14 to be erected between the lift unit 33 and the lower line 32.
- Buoyancy line unit 33 It goes without saying that the degree of bending elasticity depends on the number and design of the net layers 26, 27, 28.
- FIG. 3 schematically shows the manner in which the network 10, which is approximately tunnel-shaped in cross section, moves and behaves in a body of water 12 with wave motion. After that, stay with Wind and wave attack according to arrow A, the arcuate area 37 always above the water surface 15, in particular also when the arcuate area 37 is deformed. A spillover of the waves and thus of completely sucked flat structures 11 is essentially prevented.
- FIGS. 5 and 6 show the delimitation of contaminated water surface areas with the help of one or more networks 10.
- the network 10 is divided into network sections 43, which are connected with a channel-shaped hose 44 in the connection area of the control network 13 and the grid network 14, but in the remaining areas are directly held together.
- a network 10 consisting of two network sections 43 can be used with the help of a ship 40 and a buoy 39 or with the help of two ships 40 to delimit the relevant water area.
- a plurality of networks 10, each consisting of two V sections 43 arranged in a V-shape, are connected to one another, so that they form a barrier to a water area off the coast 45.
- the respective V-shaped network sections 43 are connected directly to neighboring ones and are held, for example, by anchors 46, while the network sections 43 are connected to one another via a disposal hose 44.
- the network 110 has a first actuating network 113, a flexible power supply unit 114 connected to it in one piece, which can erect in an arc shape, and a second actuating network 120 connected in one piece with the flexible power supply unit 114.
- This thus consists of the first actuating network 113, the flexible power supply unit 114 and the second control network 120, for example a network 110 which is constructed in one piece, is preferably composed of a network Known fishing technology fishing net made of pliable material, only the mesh size can be adapted to the use described above.
- the network 110 can thus have a length of one or several hundred meters, which is customary in fishing technology, its width deviating from this in that the first control network 113, which has a width corresponding to the fishing networks, on the one hand by the flexible power supply 114 and on the other is broadened by the second control network 120.
- the power supplies 113, 114 and 120 can each be manufactured separately and then connected to one another at their longitudinal edges. All power supplies 113, 114 and 120 are single-layer network arrangements.
- the two adjusting nets 113 and 120 are connected to one another at their free longitudinal ends 117 and 124, as shown in FIG. 7, and there they have a common lowering element 118 in the form, for example, of a lowering line equipped with lead balls.
- the two merged and connected lower longitudinal ends 117 and 124 are also connected to a longitudinally extending traction line or traction cable 125.
- the flexible power supply 114 which is also referred to below as an arch network 114 due to its active positioning, is designed to be elastically resilient or flexible in the direction of its width due to the arrangement of flexible rods 150.
- the flexible rods 150 are provided and arranged at a preferably uniform distance over the length of the arch network 114.
- the flexible rods 150 can be firmly connected to the arch network 114 at certain intervals. It is also possible to thread the flexible rods 150 through the meshes of the arch network 114 in a specific arrangement in order to achieve a corresponding connection of the arch network 114 and flexible rods 150. In this case it is sufficient to connect the ends of the flexible rods 150 to the arch network 114 via, for example, cable ties.
- the flexible rods 150 are made of a non-metallic material, for example a plastic or a plastic laminate, such as, for example, plastics which are reinforced with glass fiber or carbon fiber.
- the cross section of the flexible rods 150 can be designed according to the desired flexibility, for example circular, rectangular, oval or the like; they can also be hollow or made of solid material or any other cross-sectional fillings. The material used is selected so that it is not attacked by the contaminants.
- the arched net 114 is also provided with lowering elements 132 and 135 at its longitudinal ends connected to the two adjusting nets 113 and 120, which can be composed, for example, of ropes equipped with lead balls.
- lowering elements 132 and 135 at its longitudinal ends connected to the two adjusting nets 113 and 120, which can be composed, for example, of ropes equipped with lead balls.
- buoyancy elements 121 and 133 which, in the exemplary embodiment shown, consist of a plurality of individual elongate elements arranged parallel to one another Plastic strips 151 exist.
- a closed-cell foam plastic is provided as the plastic for these buoyancy strips 151.
- plastic strips 151 are arranged parallel to one another and thus define a buoyancy element 121 or 133.
- the plastic strips 151 are arranged in the longitudinal extension of the arch network 114 and are firmly connected to this network, for example alternately threaded through the meshes of the arch network 114 and held at their ends. It goes without saying that other fastening options or arrangements can also be provided, for example that these longitudinal edge regions of the grid network 114 can be encapsulated by appropriate foam plastics. This too Material is selected so that it is not attacked by the contaminants.
- the shape resulting from an arch and a V arrangement results, ie the two positioning nets 113 and 120 form an approximately V-like shape with one another, while the arch network 114 forms an arc shape due to the flexibility in the transverse direction and due to the lowering and buoyancy elements.
- the lowering and buoyancy elements 132, 135 and 121, 133 of the network 110 are also balanced in such a way that the arch network 114 extends from a region of the buoyancy elements 121, 133 below the water surface 115, but with the essential part of the arch-shaped region above the water surface 115 located.
- the two setting nets 113 and 120 are of equal width, while, as shown in FIG. 8B, the grating 114 has a width which is either equal to the sum of the width of the two setting nets 113 and 120 or somewhat less than the two setting network widths taken together.
- the net 110 assumes an essentially flat shape when it is brought out of the water. This is because the grid 114, due to its flexibility and that of the rods, automatically returns to a flat position outside the water, so that the two positioning nets 113 and 120 are also pulled out of their V-shape into a substantially flat position, and depending on the width, only sag a little from the flat grid 114.
- This form of the net 110 in a so-called dry positioning enables the net 110 to be easily unwound and unwound from or onto a drum attached, for example, to a ship.
- This possibility of unwinding and winding is supported by the fact that the flexible bars 150 lie transversely to the winding direction and that the plastic strips 151 are designed so that they can be wound. If the net 110 is discharged from this wound flat state into the body of water 112 while being unwound from a drum, the shape shown in FIG. 1 automatically results in the body of water 112 due to the configuration and balancing or dimensioning of the buoyancy and lowering elements.
- the positioning of the network 110 in the water 112 generally remains in the manner shown in FIG. 1. Only when there is double-sided water pressure on the network 110, in particular in the sea, will this change to the cross-sectional shape shown schematically in FIG. 3 without the desired active position or positioning of the network 110 in the water 112 generally changing.
- the design of the network 110 entails that only the V-shape of the adjusting networks 113 and 120 and the arch shape of the arc network 114 change by being compressed. This has no effects on the use or application of the network 110.
- the flat structures 11, 111 are made of open-cell foam plastic, for example open-pore foamed PP or PU or PE - Soft foam attached under the surface of the water, so that it is on the surface of the water can soak up the contaminants.
- open-cell foam plastic for example open-pore foamed PP or PU or PE - Soft foam attached under the surface of the water, so that it is on the surface of the water can soak up the contaminants.
- one or more nets 10, 110 are unwound as a flat structure from a drum 41 on a ship 40 and deployed onto the water surface 15, 115, the network 10, 110 being set up like a tunnel.
- Two or more network sections 43 are connected to one another via a disposal hose 44, and the free ends of the outer network sections 43 are connected to buoys 39 or anchors 46 and / or ships 40 via traction cables.
- Contamination area on the water surface 15 can be encircled by one or two ships 40 or the network sections can be designed zigzag in front of the coast.
- the contaminated sheet-like structures 11, 111 are suctioned off via the hoses 44 and treated or disposed of in a station.
