The invention relates to shipbuilding, in particular, to devices for collecting oil from the surface of water,

The purpose of the invention is to expand the operational capabilities of the vessel and increase the efficiency of oil-product collection.

i FIG. 1 shows a vessel for collecting oil from the surface of the water, viewed from above, FIG. 2, section 2 - D in FIG. 1; FIG. 3 is a section BB in FIG. in FIG. A, node I in FIG. 2; FIG. 5 is a view B of FIG. 1,

A vessel for collecting oil from surface and water consists of a left hull 1 and; a right hull 2 containing containers for collected oil. The bow tips of each hull are in the form of a waterline, ensuring that oil is captured with a width equal to the maximum width of the vessel. The groups of boom sections containing panels 3, buoyancy elements, end posts 5 connected to the bars 6 and bolts 7 with panels 3 are located between the hulls obliquely to the center plane of the vessel. 8 Stubs 8 are placed between the body 2 and the end posts 5. connected to the end posts 5, the latter are connected from two sides at equal distances with closed chains 9, missed in the fore and aft ends through gears 10 with drives (not shown), placed in the 1 and 2 Ends respectively. The second pillars 5 have horizontal rollers 11 and vertical rollers .12 placed in rails connected to the sides of bodies 1 and 2, and consisting of two lower 13 and two upper 1.4 legs on body 2, two lower 15 and two upper 16 branches on the body 1.

The lower and upper branches of the guides repeat the shape of the chains 9. One of the branches 13 of the hull 2 and the branches 15 of the hull 1 is located below the waterline level. The branches 15 and 16 of the hull 1 are located on the stern ends of the boom sections and are mounted on the brackets 17 to form to the length of the vessel, the free channel 18 between the boom barriers and the hull side 1,

In the aft end, on the side of the said duct 18, an oil receiver is placed, having a reservoir 19

connected by a flexible pipe 20 to a pumping pump and containers for collected oil (not shown), a ballast tank 21 connected by flexible pipes 22 to a ballast pump, a horizontal plate 23 and walls .4 connected by brackets 25 with horizontal rollers 26 placed in vertical guides 27,

The connection of the end posts 5 of the booms with closed chains 9 has a plate 28 with a shaped notch fixed on the end stand 5, a plate 29 with a figured tip coinciding with the notch of the plate 28 fixed on the chain 9, a stopper- connector 30 with pins 31, a latch 32, a latch 33, the upper branches 14 of the guide housing 2 and the branches 16 of the housing 1 have removable restrictors for the movement of the boom obstacles, made, for example, in the form of rods 34 with pins 35, passed through Figured notches 3.6 in the branches x 14 and 16 and snaps 37.

The vessel works as follows

In the traveling position, all areas of the booms are located on the upper branches x 14 of the body 2 and the branches x 16 of the body 1 between the restrictors of the boom movements and assembled into a bag (dotted line, figure 1). The latches 37 are released; the rods 34 of the movement stops after turning to match the pins 35 and the figured cuts 36 are removed.

The locking connectors are disconnected from the end posts 5 of the boom barriers and chains 9 and stored on the decks of buildings 1 and 2.1. The drives for moving the gears 10 on both sides are switched on, at the time of the coincidence of the shaped cutouts of the plates 29 on the chains 9 and the plates 28 on the end posts 5 The extreme portion of the side barriers in the package drives off. The locking connectors 30 from the two sides are passed through the plates 29 and 28, rotated through the rods 32 around the axes and fixed in this position by the latches 33. The gear drives 10 are again turned on until the matching plates 29 on the chains 9 boom obstacles Repeated operation with the establishment of the stoppers-connectors 30, The first of the established sections of the package bono

The barriers are separated from the second and a predetermined value determined by the position of the plates 29 on chains 9. Thus, all sections of the booms are successively fixed on chains 9 at equal distances from each other.

The vessel is ballasted up to. working waterline

The oil receiver is lowered into the water along the rails 27. Depending on the thickness of the oil film, the horizontal 23 plate is buried by means of a ballast tank. 21, piping .22, connected to the point-and-point pump. The oil transfer pipeline 20 is connected to a cargo pump and containers for the collected oil.

Oil trawling is carried out at high speed of the vessel. As the ship moves, the oil enters the space between hulls I and 2. Due to the burial of hulls 1 and 2 and the shape of the waterline hulls, the trawling width is equal to the maximum width of the ship. The boom sections are synchronously moved by means of chains 9 passed through gears 10 connected to the drives along branches 13 and 15 in the direction opposite to the vessel’s movement at a speed lower than the vessel’s speed and allowing booming speed at a favorable speed water barriers are below critical when

intensive oil leakage occurs under the side fences. The oil is concentrated in the narrow channel 18 and moves to the aft end of the vessel. At the stern tip, the end posts of the 5. boom transitions on the left hull 1 to the upper branches 16, and on the right hull 2 to the upper guiding branches 14, and move to the bow of the vessel. The distance between the boom sites is chosen so that, with the maximum allowable, in terms of a satisfactory percentage of recovery, oil, the ship’s speed and the corresponding maximum speed of the boom sites relative to the oil-to-film booms between two adjacent boom sites, completely

concentrated in duct 18 over a period of time the movement of these two sections of the boom obstacles from bow to stern. In addition, the distance between the boom sites should allow free flow of water under the boom; not creating stagnant zones. In the space between buildings 1 and 2, the influence of waves on the oil recovery process of the donkey is hampered by the presence of brackets 17 buried beneath the surface of the water and the splitting of the water surface by bonded barriers. part of the side barriers and the presence of elements 4 buoyancy.

The oil film is effectively captured by an oil receiver with a bottom horizontal plate 23 and side wall 24, forming a closed volume. The presence of a horizontal bottom pan 23 allows trapping oil at high speed without having it ruptured under the oil receptacle. The small size of the oil reservoir and the c-bottle beyond the level 0 of the oil film allowed collecting oil with a small amount of water. The pumped-out oil concentrated in accumulator 19 is supplied (about the pipeline 20 in the tank for the collected oil

After the end of the oil recovery, the curdling device is removed. The oil receiver is lifted out of the water and secured. With the help of gear drives 10, the first

The area of the booms is brought to the installation site in the branches 14; H 16 paralyzing travel stops 34 and stops, the Travel Limiters 34 from two boards 4g are inserted into the figured cutouts of the Zb, turned and fixed with latches -: 37, Hotshots 33 I of the stoppers-connectors of the first section, iKa of booms, are released, the stoppers are connected with I t and 32, and are removed from the plates 28 and 129, the chains 9 receive freedom of movement relative to the end posts 5 of the first section of the boom obstacles, her and yourself The end posts 5 are fixed by movement limiters 34. Drives for moving gears 10, follow up at the boom points are included. Citizens are brought to the section 9 located at limit stops 34 of the displacement. The end posts of the side fences 5 from the chains 9 are disconnected again. The operations are repeated for all subsequent sections of the side fences. The last portion of the booms collected in the bag is prevented externally by movement limiters 34.
