SHIP FOR RECOVERING OCEAN WASTE

Abstract

The present invention relates to a ship for recovering ocean waste. The ship for recovering ocean waste according to the invention has at least one tank (3) that passes through the ship from the prow (6) to the stern (7), the tank (3) being open at its two ends and being equipped with at least one row (10, 20, 30, 40, 50, 60, 70) of collecting devices (8). The ship according to the invention is characterized in that the collecting devices (8) of at least one row are disposed such that they have openings (5) or spaces (5) between one another. This disposition of the collecting devices allows fish to pass easily through the rows of devices, while waste is collected efficiently.

Description

[0032] The invention is explained more precisely below with reference to the attached figures which show embodiments of the invention in a schematic manner:

[0033] FIG. 1 is a purely schematic illustration of several embodiments of pick-up devices in a ship according to the invention in horizontal section;

[0034] FIG. 2 is a purely schematic illustration of another embodiment of the pick-up devices in a ship according to the invention in longitudinal section;

[0035] FIG. 3 is a purely schematic illustration of an embodiment of a ship according to the present invention with a basin of reduced width in relation to the width of the captured water layer.

[0036] It is specified that the figures show the invention in a purely schematic manner to explain its general mode of operation. The figures are neither to scale nor complete but show schematically only those elements which are necessary to appreciate the invention.

[0037] FIG. 1 shows several different possibilities of arranging the pick-up devices 8 in a ship 1 according to the invention in horizontal section. The ship comprises a basin 3 which is confined by the ship's hull 2.

[0038] For illustration purposes only, the figure shows several rows of pick-up devices 10, 20, 30, 40, 50, 60, 70, each with a different arrangement.

[0039] Row 10 has pick-up devices with spaces between them to allow fish to pass through.

[0040] Optionally, the spaces can be covered by beams or hoods or fairings 4 which are positioned at a suitable distance in front of the openings in the row of pick-up devices. The figure shows several shapes of beams or hoods or fairings that are particularly advantageous. The beams or hoods or fairings 4 can, for example, be triangular or rounded in shape. They may also be flat, provided that they are preferably oriented at an angle of about 30 to 60 to the direction of travel of the ship.

[0041] The beams or hoods or fairings 4 increase the efficiency of the pick-up devices 8 and at the same time reduce the cost compared to a complete row of pick-up devices over the full widths of the basin.

[0042] Fish can easily pass between a beam or hood or fairing 4 and a pick-up device 8 to a space 5 between two pick-up devices. However, the waste is diverted through the beams or hoods or fairings 4 to the pick-up devices 8 and is collected efficiently.

[0043] Row 20 is a double row of devices according to row 10, arranged in a staggered manner to allow on the one hand fish to pass and on the other hand to collect all waste, including waste passing through the spaces of the devices further forward in relation to the direction of travel D of the ship.

[0044] Row 30 corresponds to row 20, but the pick-up devices are arranged overlapping on their edges.

[0045] Rows 40 and 50 have devices that are staggered, without overlapping edges for row 40 and with overlapping edges for row 50.

[0046] Rows 60 and 70 have devices which are arranged at an angle to the direction of travel D of the ship, without overlapping edges for row 60 and with overlapping edges for row 70.

[0047] FIG. 2 shows an alternative arrangement of the pick-up devices in a ship 1 according to the invention in cross-section. The devices 80 are arranged vertically staggered to allow fish to pass through the spaces between them.

[0048] FIG. 3 shows a ship 1 with two side hulls 2 each having a bow tip 22, off-centered outwardly. The width of the hulls increases in the first section of the ship towards the stern 7 of the ship such that the width of basin 3 decreases.

[0049] A first row 10 of pick-up devices 8 for picking up large waste is located near the entrance to the basin in the reduced width section. The pick-up devices have spaces between them to allow fish to pass through. At this first row 10 the width of the basin is reduced to the maximum in relation to the width of the captured layer of water L1 between the tips 22 of the hulls 2. The pick-up devices in this section are particularly robust for picking up large objects. They do not offer much resistance to the passage of water. The increase in water speed has no particular effect.

[0050] Then there is a second row 20 of pick-up devices 8. The width of the basin in this row 20 is wider than the width in the first row 10 due to the shape of the hulls 2.

[0051] The pick-up devices designed to pick up medium-sized objects have a higher resistance to water flow and are more fragile. Therefore, the speed of water flow in the second row should be reduced. There are spaces between the devices for fish to pass through. The spaces are large enough to allow fish and waste that is smaller than the objects that are picked up by the devices in row 20 to pass through.

[0052] Towards the stern 7 of the ship, the width of the basin widens even further. Row 30 of pick-up devices is designed to pick up small objects. The devices are arranged in a horizontally staggered arrangement with overlapping edges to allow fish to pass through while still effectively picking up the waste.

[0053] Reducing the width of the ship's basin at certain locations allows a considerable reduction in the number of pick-up devices required at these locations, which reduces operating and maintenance costs but allows a considerable width of the water layer to be treated.
