TECHNICAL FIELD
[0001] The invention relates to a device for receiving oil-rich liquid from a water surface, comprising at least one float. BACKGROUND
[0002] Oil-rich liquid can reach water bodies as a result of ship accidents and as a result of negligence, for example when emptying cargo holds in a ship, or as a result of oil pipeline accidents. These water bodies can be the sea, rivers, canals, lakes or other water bodies.
[0003] In order that the escaping oil-rich liquid does not cause greater environmental damage, devices for receiving oil-rich liquid have been proposed. These can comprise suction devices, or floating barriers can be used. SUMMARY
[0004] The object of the invention is to show a device of the type mentioned at the outset, with which receiving oil-rich liquid from a water surface is achieved in a technically simple manner.
[0005] This object is achieved according to the invention in that the float has at least one groove body in its edge region at least in sections, which groove wall facing away from the float has an edge which, in the floating state of the float, is arranged above the water surface.
[0006] The device according to the invention has at least one float. The float can be arranged on the water surface, it can be brought close to the diffusion of the oil-rich liquid. According to the invention, the float is equipped with a groove body, wherein the groove body is arranged in the edge region of the float. These edge regions of the float are close to the water surface, i.e. the groove body is arranged near the water surface.
[0007] The groove body is arranged at the float according to the invention with a structure height. The structure height is chosen such that the groove wall facing away from the float has an edge which is arranged above the water surface. The groove body can be arranged at the float such that it lies within the water surface. The groove wall facing away from the float then emerges from the water surface, the edge lying above it is arranged above the water surface. This arrangement causes the wave motion to be able to rock over the edge of the groove wall and to bring the oil-rich liquid, which is loaded, into the groove body. By the corresponding natural motion of the water surface, the oil-rich liquid is brought into the groove body, which is separated from its groove wall facing away from the float. The float can also be actively moved in the direction of the oil-rich liquid.
[0008] In the floating state of the float, the edge of the groove wall is preferably arranged a few centimetres above the water surface. The water surface, with its surface at the outside of the groove body, by the motion of the water surface, liquid with oil-rich liquid components can pass over the groove wall into the groove body.
[0009] For optimal separation of the oil-rich liquid from the water surface, it is suitable that the float body rests statically on the water surface. This is preferably achieved by a large raft-like construction of the float body. It can have dimensions of ten by five meters, for example.
[0010] According to an improvement of the application, at least one liquid removal line is arranged at the channel body. The oil-rich liquid that enters the channel body is removed from the channel body again by means of the liquid removal line and supplied to a utilization or disposal. The liquid removal line is preferably configured as a suction line, it being possible for at least one pump to be coupled to the line.
[0011] According to a further improvement of the application, the float body can also be provided with connecting means for connecting to other, preferably identically constructed, float bodies. With the connecting means, one float body can be connected to another, for example in order to provide a larger, in particular longer, channel body. With these connecting means, however, it is also possible to connect a plurality of float bodies to one another such that they enclose an area of the water surface. In this area of the water surface, for example, a distressed ship can be arranged, which can also be a leaking oil rig, etc. As with the known floating barriers, a chain of float bodies with channel bodies is configured with the device according to the application. On the one hand, in order to prevent the oil-rich liquid from spreading, but on the other hand also in order to receive these oil-rich liquids with the channel bodies. BRIEF DESCRIPTION OF DRAWINGS
[0012] Embodiments of the application are shown in the drawings. Therein: Figure 1 A view of the device according to the application for receiving oil-rich liquid in a water surface is shown, Figure 1a A further sectional view of the device according to the application is shown, Figure 1b A top view of the device according to Figure 1a is shown, Figure 2 A top view of a large number of devices according to Figure 1 the application in an arrangement that encloses a sea vessel is shown, Figure 3 A top view of a number of devices according to Figure 1 the application in a manner that encloses a rig is shown. DETAILED DESCRIPTION
[0013] Figure 1 The device according to the application in
[0014] The float body 1 floats on the water surface 2. The float body 1 has a platform 3, at which a floating container 4 that is immersed in the water is arranged. Figure 1At the edge region on the right side there is a trench body 5. The trench body 5 is fastened at the floating container 4 of the floating body 1. Like the floating container 4, the trench body 5 is immersed in the water below the water surface 2.
[0015] The trench wall 6 facing away from the floating body 1 has an upper edge 7, which is arranged above the water surface 2 in the floating state shown in Figure 1 . The arrangement is achieved only a few centimeters above the water surface 2, so that the oil-rich liquid floating on the water surface 2 can enter the trench body 5 according to the arrow 8. The entering oil-rich liquid can be removed from the trench body 5, for example, via a suction nose, but can also be guided via a line 9 into the platform 3 and there to a connection piece 10, to which a suction line can be coupled.
[0016] In Figure 1a different suction of oil-rich liquid is shown. The line 9 is guided directly from the trench body 5 into the region above the water surface. The floating body 1 carries a further line 9'.
[0017] Figure 1b The top view in shows the association of the floating body 1 and the trench body 5 to each other.
[0018] The device according to the invention can be used in single form, as shown in Figure 1 , Figure 1a and Figure 1b . Conversely, Figure 2 shows that a plurality of floating bodies 1 can be connected up to surround a sea vessel 11. The floating bodies 1 have connection means for connection to other floating bodies 1, which are not further shown, which can be connected to each other in a chain as shown in Figure 2 . Figure 2 shows that the sea vessel 11 is surrounded by trench bodies 5. In the same way of surrounding, lines 9 for the suction of captured, for example, oil are associated with the trench bodies 5. The lines 9 are guided to a central oil pump 13.
[0019] Figure 3 An application case is also shown here, in which a plurality of floating bodies 1 around a drilling tower 12 are oriented approximately square. Here, Figure 3 in detail also shows the trench bodies 5 and the lines 9, which here are also guided to a central pump 13.
[0020] In Figure 2 and also in Figure 3 a leak 15 of a sea vessel 11 or a drilling tower 12, respectively, is indicated. The escape of oil-rich liquid is indicated accordingly by the wave 15.
