Abstract

The invention relates to a boom system which can simultaneously serve as a barrier and as a temporary storage device. The concept provides several basic elements which can be joined in a Lego-like" manner. According to the invention, these pieces are not only longitudinally but also transversally interconnected to produce linear, star-shaped and reticular barriers. The basic element consists of lightweight double film tubes which are pre-packed in bundles. The length of the film double tubes can be adapted to suit the particular situation and can range, for example, between 5 and 400 meters. This novel system can be combined with heavy booms of the prior art to be used for very serious accidents. It is, however, particularly suited for small and medium-sized booms, whereby the oil can be collected and accommodated advantageously using skimmers.

Description

Dirt trap

The invention relates to a dirt barrier, which is particularly suitable for laying in water.

Dirt barriers of this type are already known. However, this has the disadvantage, among other things, that the design of the barrier in the water is relatively complicated. As a result, the interpretation of the known barrier in the water is relatively slow. This is particularly disadvantageous when there is a risk of rapid verse use of a body of water.

One of the objects of the present invention is to provide a device which enables a quick design of dirt barriers.

This object is achieved according to the invention in the establishment of the type mentioned in the introduction, as defined in the characterizing part of patent claim 1.

Fig. 1 shows one of the possible situations when laying out the present pollution barrier in the water. Fig. 2 shows one of the embodiments of the present pollution lock in perspective. This lock has a common anchoring part 10, which is buoyant. This main or anchoring part 10 can also be referred to as a buoy. This buoy 10 can be anchored in place with the aid of anchor cables 9. Of these, only one of the anchor cables 9 is drawn in FIG. 2. In the case shown, the buoy 10 has a base body 11 which is designed to be floatable. This base body 11 of the buoy 10 can be hollow or made of a floatable material, such as e.g. be made of a foam. The buoy body 11 has a triangular plan in the case shown, so that the buoy 10 has three side walls 12, 13 and 14.

The lock also includes arms 15, 16 and 17, each of which is sealed at one end to one of the side walls 12, 13 and 14 of the buoy 10. The respective arm or the respective section 15 or 16 or 17 of the barrier extends away from the buoy 10 and they are practically at right angles to that side wall 12 or 13 or 14 of the buoy 10 to which the section 15 or 16 or 17 is connected

3 schematically shows a section through one of the sections 15 or 16 or 17 of the lock. The arm 15 or 16 or 17 is designed as a double hose. Such an arm 15 or 16 or 17 accordingly has a first or outer hose 21 and a second or inner one Hose 22 on The second hose 22 has a smaller diameter than the first hose 21. The second hose 22 is arranged in the first hose 21 such that the two hoses 21 and 22 extend in the same direction in the operable state

The tubes 21 and 22 are made of a resilient material, for example. of a film The inner tube 22 is designed such that it can be filled with gaseous medium, for example with air of low overpressure. Accordingly, the material of this inner tube 22 should be made of a material that is at least essentially gas or airtight. This material can, for example be a plastic film or an impregnated textile material The end regions 41 of the inner tube 22 are practically airtight.This second air tube 22 ensures the buoyancy required for the operation of the barrier in the barrier section in which the inner tube 22 is located.The high pressure of the gaseous medium in the Inner hose 22 is selected such that the jerk of the barrier protrudes from the water surface to the desired extent so that the barrier can perform its barrier function in the area of the water level

At least one valve 20 is arranged in the upper area or in the back area of the second hose 22, through which the gaseous medium can be introduced into the second hose 22. The valve 20 should be designed so that it enables the inner hose 22 to be inflated, since it prevents it that the air escapes from the inner hose 22 in an uncontrolled manner and that the air comes out after the operation of the lock has ended can escape from the inner tube 22 in a controlled manner. Such valves 20 are known and are available on the market. The valve 20 passes through the material or through the spine 24 of the first sleeve 21 so that the valve 20 is accessible from the outside

In the illustrated case, the respective end region of the arm 15 or 16 or 17 is provided with two valves 20 each. The valves 20 of the respective pair are arranged one behind the other in the longitudinal direction of this hose 22. The two valves 20 of the respective pair in the end region of the inner hose 22 are in one small distance from each other and they are as close as possible to the end wall 41 of the inner tube 22nd

The two hoses 21 and 22, when fully filled with a fluid, would have a circular cross-section, as indicated in Fig. 3. In fact, only the inner hose 22 has a practically circular cross-section when this hose 22 contains the gas The space 23 between the inner air hose 22 and the outer hose 21 is filled with a liquid medium 23 during the operation of the barrier. Normally, water is this liquid medium. The inner hose 22, because it is filled with a gas, floats up in the intermediate space 23 this inner tube 22 is the back 24 of the outer tube 21 and in this way the inner tube 22 carries the outer tube 21 in the water Zumi run parallel to each other During the laying of the barrier, when the section 15 moves, water flows through the interior 23, so that the basic body of the outer tube 21 has a rather egg-shaped cross-section. The material of the outer tube 21 is subject to these circumstances with regard to its impermeability no high demands are made of this Mstenal can be, for example, a non-woven fabric or a plastic flute

The hoses 21 and 22 can otherwise be designed in a manner known per se It is crucial that at least one floatable chamber 22, filled advantageously with a gaseous medium, is located above the liquid, eg above the water, which performs the desired barrier function, and that at least one chamber is located below, ie in the liquid , which contains a liquid medium, eg water.

FIG. 4 shows, simplified and in a vertical section, the connection of one of the end parts of the arm 15 or 16 or 17 to the buoy 10. In the case shown in FIG. 4, the connection of the first arm 15 to the buoy 10 is vertical Section shown. The connection is made with the aid of a first coupling device 25. This device 25 comprises a flange 26 which has an essentially annular base body 27. The inner surface of this base body 27 is convex and also roof-like, so that this inner surface has two roof sides 28 and 29, between which an obtuse angle extends. This angle can only be a few degrees smaller than 180 degrees. In the outer surface 51 of the base body 27, circumferential grooves 31 and 32 are embodied, which expediently have a square cross section. One of these grooves 31 or 32 is assigned to one of the edge or end parts 33 or 34 of the flange 26. The respective groove 31 or 32 runs practically parallel to the relevant end part or surface 33 or 34 of the flange 26.

For receiving the flange 26 of the first coupling device 25 on the buoy 10, a socket 35 is attached to the outside of the respective side wall 12 or 13 or 14 of the buoy. This mount 35 has an approximately plate-shaped or disk-shaped base body 36. This plate 36 has a flat upper or large surface 37, which is assigned to the side wall 12 of the buoy 10. The mount 35 is fastened to the buoy 10 via this large area 37. In the opposite large surface of the pane 36, ie facing away from the buoy 10, there is a flat recess or depression 38. The course of the side wall or the edge of this recess 38 corresponds to the course of the outer contour of the base body 27 of the flange 26. The first end part 33 of the flange 26 faces the first side wall 12 of the buoy 10 and is assigned to the holder 35. The the The end face 34 of the edge of the flange 26 lies in the recess 38. Means 39 are provided which hold the mentioned edge region 34 of the flange 26 in the recess 38. These means 39 can be designed, for example, as a tensioning or locking mechanism. Said means 39 engage, for example, in the first groove 32 of the flange 26, as a result of which the flange 26 can be fastened to the buoy 10, which can also withstand strong waves.

The respective end section 47 of the outer shell 21 of the arm 15 or 16 or 17 is open. This also applies to that end section 47 which is assigned to the buoy 10. The length of the outer sleeve 21 in its circumferential direction corresponds to the length of the circumference of the flange 26. It is therefore possible to cover the end part 47 of the outer hose 21 over the edge part of the flange 26 which has the opposite circumferential groove 31. This end part 47 of the outer casing 21 is pulled over the edge 33 of the flange 26 until this hose end part 47 bridges or covers the second circumferential groove 34.

A device 40 is provided, by means of which the end part of the outer hose 21 can be fastened on the edge part 34 of the flange 26. This fastening device 40 can be resilient or closable and it is also designed so that it fits into the circumferential groove 31. This device 40 should also be designed so that the connection between the flange 26 and the outer tube 21 has a high tensile strength. The device 40 can be designed, for example, as a fastening ring which is placed on the outside of the end section 47 of the outer casing 21, which surrounds or covers the said circumferential groove 31 of the flange 26. Depending on the design of the ring 40, this can be closed automatically, for example because of the effect of a prestressing force inherent in the ring 40, or by using an external force. In this case, the ring 40 presses the part of the end section 47 of the outer casing 21 lying below this into the circumferential groove 31, as a result of which the outer casing 21 is fastened to the flange 26 mentioned. Since this flange 26 is connected to the buoy 10, which is anchored, this end 47 of the sections 15 and 16 also applies or 17 as firmly anchored. The opposite end section 47 of the outer tube 21 is provided with a further flange 26 in the manner already described above.

This last-mentioned end section 47 of the barrier body 15 can be connected to a towing boat 2 with the aid of a towing device 4. This towing device 4 comprises a main cable 41 and branch cables 42, 43, 44 and 45 connected to it. One end of the main cable 41 is connected to the towing boat 2. The first or common ends of the branch cables 42 to 45 are fastened to the other end of the main cable 41, so that these branch cables 42 to 45 branch away from the main cable 41, specifically against the end part 47 of the locking arm 15 mentioned. The branch ropes 42 to 45 form an upper group and a lower group, each of which comprises two of the branch ropes 42 and 43 or 44 and 45. The other ends of the branch ropes 42 to 45 can be connected to the last-mentioned end flange 26.

A further hose 5 is provided, which is connected at one end to one of the valves 20 on the inner hose 22. This end of the compressed air hose 5 is connected to the end part of the locking arm 15 facing the tugboat 2. A compressed air source 3, e.g. a fan is available to which the other end of the compressed air hose 5 is connected. The inner hose 22 can be inflated via the compressed air hose 5 when the compressed air source 3 is in operation.

There are applications for which the length of a section 15 etc. of the lock is too short. In such cases, two practically identically designed locking bodies 15 or 16 or 17 can be connected with one another or in series with the aid of a single coupling flange 25, as is indicated in FIG. 5. The mutually facing, open end parts 47 of two locking bodies or sections 15 to be connected together are slipped over the opposite edge parts 31 and 32 of the flange 26 and connected to the coupling flange 26 in the manner described above with the aid of two fastening devices 40 (FIG. 7). Since the end sections 47 of the outer tubes 21 are open, the water can flow freely between the interiors 23 of the outer tubes 21 connected in series. As a result, for the very light film double hose 15 or 16 or 17, the coupling section 26 does not act as a disturbance for the play in the movement of the hose in the light currents or wave movements in the water.

The ends 41 of the inner tubes lying in the region of this connecting flange 26

As already mentioned, 22 are practically airtight. The mutually facing end parts 41 of the inner tubes 22 lying one behind the other can be spaced apart from one another, so that these end parts 41 are also at a distance from the base body 27 of the flange 26 and thus also from its inner sharp cards 28 and 29. These distances are important because the film material of the inner tubes 22, for example during waves, could be worn through the edges 49 of the flange inner sides 28 and 29.

So that the buoyancy in the area of the coupling flange 26 is in equilibrium with the rest of the barrier, the foil air hose 22 can be designed such that it displaces the water in the upper part of the barrier. In this case, the end walls 52 of the mutually facing end parts 41 of the inner tubes 22 lie in the interior of the coupling flange 26. However, in order to prevent the soft and resilient material of the inner tube 22 from being damaged by the aforementioned inner edges 49 of the flange 26, an indentation 48 be designed in that area of the inner shell 22 which lies opposite the respective inner edge 49 of the flange 26.

A bridging line 50 is provided in order to achieve a slight and uniform overpressure in the adjacent inner air hoses 22. One end part of this bridging line 50 is connected to one of the valves 20 of one of the foil air tubes 22 connected in series. The other end of this line 50 is connected to one of the valves 20 of the adjacent film air hose 22. This line 50 between two adjacent air hoses 22 remains in permanent connection with the adjacent inner hoses 22 in the designed state of the barrier. The bypass line 50 is provided with a further valve 20. This valve 20 can be used in particular when the lock is composed of several to many sections 15 or 16 or 17. The cross section of the bridging hoses 50 is small in comparison with the cross section of the inner hoses 22. In the case of locks, which consist of a plurality of sections 15, etc., connected in series, the air resistances of the individual bridging hoses 50 could add up to such an extent that the inner hoses 22 which are the most distant from the air source 3 (FIG. 1) would not receive enough air to allow the ensure the necessary buoyancy of the relevant section 15 or 16 or 17. In such cases, additional air sources 3 can be used, which are arranged distributed along the barrier. Each of these air sources 3 can be connected to the valve 20 of the bypass line 50 which is closest to this bypass line 50. Depending on the selected design mode, it is possible to fill with the gaseous medium with the help of a second boat 2 at the other end of the lock.

The filling of the contaminant barrier with water can take place, for example, in such a way that a pulling device, e.g. the boat 2 (Fig. 1), to which one end of the lock is connected and set in motion. Here, the water flows through the end of the barrier facing the traction device 2 and fills the space 23 in the successive barrier sections 15, etc.

If you want to form a self-contained lock only from the individual sections 15, 16, 17, etc., kinks would occur in the sections buttly connected to one another via the coupling flanges 26, so that a circular or oval-shaped lock can be created, for example. This problem can be solved by using the buoys 10 already described, for example with the triangular plan. As explained, the respective section 15 or 16 or 17 is practically at right angles to the relevant side wall 12 or 13 or 14 of the buoy 10. Consequently, the adjacent sections, for example sections 15 and 17, close (FIGS. 1 and 2). an angle between them that is less than 180 degrees. In the present case this is Angle 120 degrees In this case, a self-contained barrier could be formed from six sections 15 and so on and six buoys 10 without forming kinks in the barrier sections 15 and so on. It was clear that buoys 10 were based on a pentagon or hexagon etc. can be used to build barriers in which the angle between the adjacent sections is more than 120 degrees. With the help of such buoys 10 self-contained barriers with sections of a predetermined length and without kinks, the diameter of which is much larger than the diameter of the self-contained barrier which buoys 10 with the triangular base uses

FIG. 6 shows a front view of one of the possible designs of that coupling flange 26 which has already been partially described in connection with FIG. 5. The flange 26 according to FIG. 6 has a practically egg-shaped circumference, the narrow section 58 of this flange 26 changing during operation of the Lock located above The opposite section 59 of the egg-shaped flange base 27 is located during operation of this barrier below. This lower section 59 delimits the interspace 23 of the lock in the region of the flange 26, where water is located during operation of the barrier. The opposite end parts 41 of the inner tubes 22 (FIG. 5) arranged one after the other are located in the region of the upper portion 58 of the flange 26

The coupling flange 26 has four eyelets 61, 62, 63 and 64, which are arranged on the outer side of the base body 27 of the flange 26. FIG. 7 shows a section BB through one of these eyelets 61 to 64. The base body 65 of the eyelet 61 to 64 is as one Flat spout made from the circumferential surface 51 of the flange 26 The distance between the large-scale rare walls 66 and 67 of the spout 65 decreases with the increasing distance from the flange base body 27, so that the base body 65 of the spout is tapered. The greatest width of the spout 65 is accordingly in the vicinity of the outer surface 51 of the flange base body 27 However, this width is smaller than the distance between the circumferential grooves 31 and 32 due to the large surfaces 66 mentioned and 67 passes through a bore 68 through which one of the above-mentioned towing cables 42 to 45 can be passed.

The first two eyelets 61 and 62 are located in the area of the upper half of the flange base body 27, specifically in the area of the transition between the narrower section 58 and the wider section 59 of the flange 26. The remaining two eyelets 63 and 64 are located in the bottom area of the wider section 59 of the flange base body 27. The first two ropes 42 and 43 of the pulling device 30 are connected to the first two eyelets 61 and 62 and are located at a horizontal distance from one another. The second branch ropes 44 and 45 of the pulling device 30 are connected to the second or lower eyelets 63 and 64, which are likewise located at a horizontal distance from one another. The vertical main axis A of the flange 26, which halves these horizontal distances, passes vertically through said horizontal distances. Consequently, the lock is connected to the pulling device 30 symmetrically. Through such a connection of the traction device 30 to the lock, the tractive forces of the tractor 2 are optimally transmitted into the lock during the construction of the lock. This effectively reduces the risk of the lock tearing in the event of extreme fluctuations in the tensile force or in the event of high swell.

FIG. 8 shows the flange from FIG. 6 in a cross section C-C. A further projection 53 protrudes from the inside of the flange base body 27, which protrudes from the roof sides 28 and 29. In this protrusion 53 located between the circumferential grooves 31 and 32, a radially extending opening 54 is made, which extends through the entire thickness of the ring 27. The distance between the outer surfaces 55 of the projection 53, which emerge from the roof sides 28 and 29, decreases with the increasing distance from the roof sides 28 and 29, so that these outer surfaces 55 converge, which is important because of the sensitive material of the inner tubes 22.

8 also shows the connection of two barrier sections 15 connected in series in a vertical section, which corresponds to the representation of FIG. 5. The protruding or free sections 52 of the end parts 47 of the outer tube 21 are covered on the section of the sleeve rim 47 fastened with the aid of the fastening device 40. As a result, the middle section of the flange base body 27 or between the circumferential grooves 31 and 32 is exposed.

9 to 14 show a perspective view of a further embodiment of the flange, which enables the coupling ring 40 to be clamped. 9 and 10 show the coupling flange 26 in a three-dimensional representation in two different views. In the outer side 51 of the base body 27 of the flange 26 there is a third circumferential groove or groove 69 (FIGS. 9 to 12), which is located practically in the middle between the two circumferential grooves or grooves 31 and 32 already described. The eyelets 61 to 63 already described are located in the region of this third groove 69. In the case shown in FIG. 9, the flange 26 has three eyelets. The first two eyelets 61 and 62 are located in the upper transition area of the flange 26, i.e. between the upper part 58 and the lower part 59 of the flange 26, as has already been described. The third eyelet 63 is located in the lower region of the lower part 69 of the flange 26. The flange according to FIG. 10 has only two eyelets 61 and 62, which are located in the transition area mentioned.

It may be necessary, for example due to waves or currents, to anchor sections of the barrier. For this purpose, the flanges 26 are provided with anchoring receptacles 70. The respective receptacle 70 has a material block 71 which protrudes from the outside of the base body 27 of the flange 26. In this block of material 71 there is a radially running bore 72, which is expediently a threaded bore. An end piece (not shown) of a rope or the like, which is provided with an external thread and has an anchor connected to the other end thereof, can be screwed into this bore 72. The material block 71 can be in one piece with the base body 27 of the flange 26, so that the position of this anchor took 70 in the peripheral region of the flange 26 is fixed. However, the material block 71 can also be designed such that it can be displaced in the third circumferential groove 69. This can be achieved, for example, in such a way that the side walls of the groove 69 are undercut and that a base part of the material block 71 has side tabs (not shown). , which are mounted in the undercut side walls of the groove 69 so as to be longitudinally displaceable. However, these recordings 70 can also be used for other purposes. FIG. 11 shows a section IIIc and FIG. 12 shows a section IIId in FIG. 9.

If it is to be expected that the lock will be exposed to the influence of very strong external forces, then the number of grooves 31 and 32 for receiving the end parts 47 of the outer tubes 21 can be increased. If, for example, instead of a receiving groove 31, two such circumferential grooves are provided side by side in the outer side 51 of the flange base body 27, then two fastening rings 40 can be used for holding an end part 47 of one of the outer hoses 21. In this way, the lock can also be used in extreme stress situations.

For extreme load situations, the force of a single resilient fastening ring 40 is not sufficient, because in such a situation the ring 40 must exert a very high holding force on the end section 47 of the outer hose 21 clamped in the groove 31 or 32. 13 and 14, details of a device 75 for tensioning the fastening ring 40 are shown so that it can exert the high holding force. In the illustrated case, one clamping device 75 is assigned to one of the circumferential grooves 31 and 32. However, it goes without saying that several such devices 75 can be assigned to a single receiving groove 31 or 32.

The clamping device 75 comprises a bed 76 in the base body 27 of the flange 26. This bed 76 is located in the region of the receiving groove 31 or 32 in question and it is arranged such that the groove 31 or 32 can run through this bed 76. This bed 76 also includes a sleeve 77, which continues from the inside of the flange 27 against the inside of this ring 27. At least in this section of the Sleeve 77, the bore in this is expediently provided with an internal thread. The sleeve 77 can be in one piece with the base body 27 of the flange 26. The bore in the sleeve 77 continues in the reverse direction up to the peripheral region 51 of the ring 27. It can be seen from the drawings that an indentation 78 is present in the outer surface 51 of the ring 27. In addition, there may be a lateral thickening 79 (FIGS. 13 and 14) of the ring 27 in the region of the sleeve 77. The beds 76 of the clamping devices 75 assigned to the receiving grooves 31 and 32 are, inter alia, offset from one another in the circumferential direction of the ring 27 because of these thickenings 79.

The tensioning device 75 also includes a tensioning piece 80 for the retaining ring 40. This tensioning piece 80 can be designed as a tube piece 81, which can be inserted from the outside into the outer end part of the bore in the sleeve 77. From the outside, a slot 82 is made in the wall of the pipe section 81, this slot 82 extending perpendicular to the longitudinal axis of the pipe section 81. The width of this slot 82 is such that the clamping ring 40, which is made, for example, of a steel cable, can be accommodated in this side slot 82. A screw 83 is provided, the bolt of which can pass through the pipe section 81. The bolt of the screw 83 is so long that at least the tip of the screw bolt can extend into the threaded region of the sleeve 77 on the flange ring 27.

The length of the retaining ring 40 in its circumferential direction is dimensioned such that it can be moved without a problem over the edge of the flange 26 to the closest receiving groove 31 or 32. The retaining ring 40, around which the end 47 of the film tube 21 is wound, is inserted into the circumferential grooves 31 and 32 in an untensioned state. Thereafter, the ring 40 is inserted into the side slot 82 in the pipe section 81, after which the screw 83 is screwed into the sleeve 77. Here, the pipe section 81 moves downward and takes the section of the retaining ring 40 suspended in it downward. The result of this is that the remaining part of the retaining ring 40 is drawn into the depth of the receiving groove 31 or 32 and held here, together with the part of the End section 47 of the outer hose 21 As a result, the entire coupling ring 40, including the film 47 wrapped around this coupling ring 40, is clamped and clamped securely in the groove 31 or 32. It goes without saying that for each side of the flange 26 that is to be clamped, an independently actuable tensioning device 75 is available

15 shows the flange 26 from FIG. 10 in use. This flange 26 serves as the front flange on a lock which is to be designed by a tractor 2. The towing device 30 can be connected to this front flange 26 and this flange 26 can therefore also be used as a towing or Experiments have shown that the first flange 26, on which the pulling device 30 engages, should be arranged in such a way that this flange 26 should be in a slightly inclined position. An optimal inclination lies in the range between approximately 20 to 30 degrees from the vertical The lower section 59 of the flange 26 should be in front of the upper section 58 of the flange, viewed in the towing direction. The required inclination of the front flange 26 on a lock can be achieved most simply by adjusting the lengths of the traction cables accordingly in the pulling device 30 (FIG. 1) The flange 26 shown has only three eyelets 6 1 to 63 In the case of this front flange 26 according to FIG. 15, the length of the lower branch cable 44 is smaller than the length of the upper two branch cables 42 and 43. The size of this length difference means that the angle of inclination of the front flange 26 can be set as desired. For heavy loads, a flange is used 26 with four eyelets (FIG. 6) preferred Two upper ropes 42 and 43 and two lower ropes 44 and 45 are connected to these four eyelets. In this case, the lower ropes 44 and 45 are shorter than the upper ropes 42 and 43

16 to 20 show devices by means of which one of the end parts of the outer hose 21 can be closed. This end part is advantageously that end part of the lock which faces away from the tractor 2. At this end of the lock, for example, a cover 18 can be attached, which prevents that the water while relocating the barrier from the space 23 at the far end of the barrier comes out. This is advantageous because the water jamming on the closing lid 18 acts as a weight that tries to hold this distal end of the lock in place. This is favorable for the deployment of the barrier bodies 15 etc. in the area connected to the tractor 2 and it can make the buoy 10 or similar holding devices more or less superfluous.

16 shows a side view of a first embodiment of such a termination of the lock. 17 shows this embodiment in a rear view. At the end of the outer tube 21, a flange 26 is fastened in the manner described above. The cover 18 has a base plate 85, from the edge part of which a collar 86 in the form of a short cylinder protrudes axially. The free edge of this collar 86 is designed for connection to the free edge of the flange 26. The free edge of the collar can, for example, be designed such that it cooperates with the circumferential groove 31 or 32 assigned to it. The cover 18 is provided with an opening 87 which can be closed with the aid of an additional cover 88.

18 shows a side view of a second termination of the lock. The end cover 18 also has a plate-shaped base body 85 in this case. However, this cover 18 is screwed onto the free end face 33 or 34 of the flange 26 with the aid of screws 89.

Fig. 19 shows a side view of a third embodiment of such a closure. The end cover 18 is provided with an additional water filler neck 90. This serves for filling the intermediate space 23 with a liquid medium. This medium, advantageously water, can be supplied by a pump with a corresponding hose connection (not shown). This pump can be on a ship or on the mainland. The base body 85 of the closure 18 according to FIG. 20 consists of a foil material and this material can be connected to the flange 26 with the aid of the retaining ring 40. FIG. 21 shows a perspective view of a further embodiment of the tension flange 96. This embodiment of the tension flange 96 is based on the knowledge that the train is intended to act on the blocking element in the process of being laid out, especially in the lower region of the outer hose 21. For this purpose, the present flange 96 has a base body 97 which is essentially in the form of a circular ring. The radius of this ring 97 corresponds approximately to that radius of the lower section of the outer hose 21, which is determined by the lower section 59 of the coupling flange 26 shown in FIG. 6. This base body 97 of this flange 96 thus leaves the upper section 58 of the outer tube 21 free, where the inner tube 22 and its valves 20 are located.

The present tension flange 96 is connected to the outer hose 21 in a manner known per se. From the upper section of the flange body 97, a connection extension 98 protrudes almost perpendicular to the plane of the flange base body 97, to which the submission 30, an anchor or the like can be connected. In cross-section, the flange base body 97 can be designed in such a way that it has a sharp front edge 99, so that the front edge 99 only offers the least possible resistance to the water flowing into the outer hose 21 during towing. As a result, turbulence in the inflowing water is avoided and a more uniform filling of the outer hose 21 with water is achieved.

22 and 23 show the use of the present barrier for bank protection. The flexible barrier, which is shown in Fig. 22, can be used in shallow water with gently rising banks. One of the end parts of this lock is provided with one of the end covers 18 already described. The pull end of the barrier remains open so that the barrier in the water can be designed in the manner described above. After that, the section of the barrier that encompasses the open end of the barrier is pulled to the bank. This section should be long enough so that the friction between the barrier body and the bank material is large enough to hold the barrier in place. This However, the lock can also be designed so that it is first unfolded and positioned as required. Only after this positioning is the lock filled with water. For this purpose, for example, the end cover 18 according to FIG. 19 can be attached to the water-side end of the barrier, which has the water filler neck 90.

The design of the barrier according to FIG. 23 can be used in cases in which the bank is steeper than in the case discussed above. In this case, the end of the barrier on the other side can be anchored at a fixed location on the bank, for example on a tree, with the aid of the pulling ropes 30 already described. This flexible barrier according to FIG. 23 replaces the otherwise customary bank barriers, and it can be mounted on the last part of the swimming barrier. The steps are as follows:

Attach end cover 18,

Pull the barrier up to the shore, which can be done with a cable, a barrier is placed under the barrier to protect it, and the barrier is anchored at prepared locations, trees, titanium anchors, etc.

24 to 26 show a further possibility for connecting two sections 15 and 16 of the present lock in succession. 24 shows schematically and in a vertical section the formation of one of the sections 15 of the lock which enables the type of coupling mentioned here. The end parts of the outer tube 21 of this barrier section 15 are essentially the same. The respective end section 47 of the outer hose 21 is provided with a coupling device 100, the coupling devices 100 at the two ends 47 of the outer hose 21 being essentially identical. The coupling device 100 comprises a coupling body 101, which has the shape of a non-circular and self-contained body. Such a coupling body 101 can essentially have the shape of the outline of an egg, which corresponds approximately to the shape of the flange 26 according to FIG. 6. With such a shape, the width of the ring 101 is smaller than the height thereof. Because of the non-circular shape of the Coupling body 101, it is possible to push a first such body 101 through another such body 101 by means of a double rotary movement and then to straighten it such that the first body 101 is arranged behind the second body 101 and runs parallel to it.

Such a coupling body 101 is assigned to the respective end part of the outer hose 21 (FIG. 24), the main plane of the respective coupling body 101 running practically perpendicular to the longitudinal direction of the outer hose 21. The coupling body 101 can be fastened in the respective end section 47 of the outer hose 21 in such a way that the hose end section 47 is turned back so far that the coupling body 101 can be accommodated in the interior of a resulting fold. In the illustrated case, the end portion 47 of the outer tube 21 is turned back inwards, which can be used further in the manner mentioned below. The protruding edge of this edge 47 can be connected to the remaining material of the outer tube 21 in a manner known per se.

25 shows an intermediate phase of the connection of two sections 15 and 16 of the barrier lying one behind the other. The end section 47 of the second section 16, which contains the coupling body 101, is inclined relative to the longitudinal direction of the lock, since the material of the outer hose 21 is flexible, so that this coupling body 101 can be inserted through the facing end section 47 in the section 15 above can. It is easily possible to pass the coupling body 101 of the second section 16 through the coupling ring 101 in the first section 15 because the two coupling rings 101 have a non-circular shape. Assuming that the two coupling rings 101 have the shape of the contour of an egg, the width of such a ring 101 is smaller than the height of the same. If the first ring 101 is set relative to the ring 101 through which the first ring is to be inserted so that the first ring 101 is moved through the second ring 101 in the direction of its longer axis or its height, then the first ring can 101 through the second ring 101 and be erected so that the first ring 101 is behind the second ring and is practically parallel to the second ring 101. Two sections 15 and 16 of the lock connected in this way one behind the other are shown in FIG. 26. Such a connection of two locking sections is tension-proof if the coupling bodies 101 are dimensionally stable, which is not a problem in practice.

The position of the first coupling body 101 behind the second coupling body 101 (FIG. 26) could be undefined, which could lead to the release of such a coupling. In order to prevent this, the sections of the sleeve edge 47 which are turned back inwards have thickenings at their free ends, so that the coupling ring 101 which is inserted and hooked in here is held between the ring 101 installed here and the thickening.

In connection with the handling of the lock, there is also the question of keeping the same or the sections 15, 16 etc. thereof. 27 shows that the section 15 or the sections 15, 16, etc., which have already been coupled one behind the other, can be laid flat and then rolled up. Such storage of the lock is space-saving and, moreover, it enables simple and rapid development or unrolling and laying out of the lock. After the lock or its sections have been rolled up, the resulting wrap can be stored in a pocket (Fig. 28), in a transport pallet (Fig. 29) or in a two-part container (Fig. 30) and, if necessary, also stored. In particular, if the double film of film is also stored in a transport pallet, the length of a lock stored in this way can be 100 to 400 meters in extreme cases and it can be kept ready as one piece or as many individual modules already flanged together.

The film double hose can also be kept ready on reels (Fig. 31). Of course, the different variants can be kept available in any combination, depending on the special dispositions that are suitable for use or in the manner in which they are required for an expected accident situation. 32, 33 and 34 show the possibility of storing the locks or their sections in modules. 32 shows the core functional parts of a hose module, namely two dimensionally stable coupling flanges 112 and 113 and a flexible film hose 114 folded into itself. The entire module is encased in a protective film, for example in a shrink film 115 or accommodated in a sack, which serves as a storage and transport protection against mechanical damage as well as against weather influences are determined and must be removed before use. A strong band 116, which is stretched directly around the module, can serve as a transport and storage securing device, so that the film folded in with some pressing force remains in the folded state. The solution from FIG. 32 is the only one of these three examples which, instead of the preferred and folded-up barrier according to WO 96/13638, allows the barrier to be folded in a helical manner, as is known from FR-PS 1 121 333 for the folding of textile fabrics is.

33 is based on the same basic components, but additionally has a small cross-sectional guide tube 117 for the gaseous medium and a large cross-sectional guide tube 118 for the liquid medium. The module I20 according to FIG. 33 can be surrounded by a stronger protective jacket 119. This protective jacket 119 can e.g. also be a thick-walled shrink film, which is held on one side with a drawstring 121. Before the lock is laid out, only the tension band 121 needs to be released, the gaseous medium introduced via the air connection 111 and the liquid medium via the water inlet opening 112.

FIG. 34 shows a robust module 140 with a housing 143 and a respective closure cover 144 or. 145 on the two end parts of the module, the cover 145 being shown lifted off the module 140. 34 has only one guide tube for the gaseous medium and is suitable, for example, for filling by dragging. The ejection end remains closed with the cover 144. At the start of the design, only the cover 145 is removed so that the water can penetrate through the filling opening 142. The housing 143 protects the Foil tube 114 also during a long storage period and can offer advantages where some modules with the same foil tubes are used several times, for example for training purposes.

FIG. 35 shows the module from FIG. 34 on an enlarged scale. The container 143 has a double wall 122, 123. The double wall can save weight and ensure that the module can float even if it remains in the water for a long time. Both coupling flanges 112 and 113 are made in several parts. This simplifies, above all, the assembly or the insertion and folding of the film tube 114. The film tube 114 is sealed by two inner sealing rings 224, 225 in a corresponding recess 124 of a flange ring 125 by means of screws 126, 127, 1271 with the respective coupling flange held. The locking cover can be secured in the form of a lock bolt using several bolts 128 and a matching rotating ring. The same system also serves to securely lock two coupling flanges when connecting modules. A recess 130 ensures that the closure cover 115 does not actuate the valve nose 218.

The three variants shown result in very interesting applications, also depending on the particular application. The solution according to FIG. 32 allows a large number of modules to be kept available with the lowest possible basic costs and to be designed in large lengths in the shortest possible time. The solution according to FIG. 32 allows the self-folded film tube as a double tube to be pulled out like a hand organ, depending on the intended length, to 30, 50 or 100 meters in length on the water, at the same time starting with the air filling. The lock can then be extended by any other modules. The lock design can be carried out without interrupting the air filling if in the two coupling flanges 112 and 113 a valve 116 respectively. 117 is arranged and this is forcibly opened when the subsequent one is flanged on, for example by a nose 118. Coupling can be carried out with little force in this variant, because the film material in the unfilled state follows the movement of the coupling flange like a piece of cloth and this can be inserted and clamped by hand in the next coupling flange.

36 to 38 show a buoy 10, which among other things has an analogous function as a tube module with the foil tubes. FIG. 36 shows a section Xlla from FIG. 38 for a crossing buoy. 37 shows a section XIIb from FIG. 36. FIG. 38 shows a view XII from FIG. 36. Thus, both the gaseous medium and the liquid medium can be supplied to the barrier sections 15 etc. via the buoy 10. However, the buoy in the version shown interrupts the air flow. It represents the end or the beginning of the air flow in each direction, depending on the observation. The buoy also has two other important functions. Through a bottom opening 60, water as the liquid medium can be introduced into the lower chamber via a submersible pump 161. The other important function is the possibility of crossing. With the modules described so far, e.g. only in one axis direction any length can be assembled on the X-X axis. The buoy now also allows modules or barriers to be laid across the y-y axis. This opens up a completely new dimension for the layout strategy. With regard to the coupling connections, the buoy has the same design as the corresponding ends of the hose modules. The buoy is designed to float with an optimal immersion depth. It is important for the lock function that the lock also projects in the area of the buoy approximately equally deep into the water and above the water level. Another purpose of the buoy is to anchor the site in question. The openings for the liquid medium that are not required are closed by a cover. With the buoys, a certain number of hose modules can also be used for separation. e.g. In the case of very large barrier lengths, a buoy can be placed after every 10 hose modules.

This lock can be designed in accordance with W096 / 13638 so that the following procedure is possible for the operating mode: Process for the rapid design of a bendable contamination protection barrier, which is kept ready folded up as a tube and, when laid out, is double-chambered, divided as asymmetrical, longitudinal and superimposed chambers, an upper chamber with gas or air and a lower chamber with a liquid medium as ballast . The tube can be designed on the one hand with a closed end as a sack bottom and on the other hand with an open, closable end for the liquid medium and with a closure for the gas or air filling, with adjacent or nested chambers preferably in themselves, ie folded on its own bendable walls, held ready in a container and the open side of the tube can be at one end of the container. The bendable tube can be filled on the basis of the inlet of gaseous and liquid medium, the flexible tube being stored as a package folded inside the container in the initial phase. However, the liquid chamber can also be filled with the liquid medium, ie water, as a result of dragging the container in the water until the tube is fully deployed as a contamination protection barrier. After the flexible pipe has been completely unfolded and filled with the two media, the open side can be closed. Depending on the ratio, the liquid medium can also be introduced into the lower chamber either via liquid pumps or by filling as a result of dragging. In the second case, the double hose is designed like a bag bottom at the end, or the side in question is closed by a cover. In addition to the valves, the preferred exemplary embodiment according to the new solution has an airtight chamber for the gaseous medium and an open chamber which can be closed as required for the liquid medium.
