DEVICE TO COLLECT OIL SPILLED ON WATER Russian patent published in 2013 - IPC E02B15/04 E02B15/10 

FIELD: ecology.

SUBSTANCE: device comprises an overflow element 1, a tight chamber 2 and a container 13. The overflow element 1 is formed by lattices 3, 4 connected into a wedge-shaped belt with a floating overflow mat 6 between them and a rear wall. The rear wall is arranged in the form of an air-filled tight chamber 2. A towing rope 7 is arranged at the distance from the top of the wedge-shaped belt and is connected with it by a cord 8. With one turn the cord 8 connects each pair of the radius form of the parts of lattices 3, 4 and the rope 7. Each pair of opposite parts of lattices 3, 4 with radius shape are connected with a cord 9. At the same time each third link of the horizontally arranged lattice 4 is made with extended shape and is pulled by th cord to the appropriate part of the inclined lattice 3 with radius shape to form a groove 11 in the lower part of the tight chamber 2. The groove 11 is formed for passage of oil collected in the zone of the overflow element 1 to the opposite side of the tight chamber 2. The towing rope 7 is equipped with floats 12 evenly arranged along its length with disc shape. The container 13 is arranged at the bottom and is formed by two strips of films 14, 15. Lower longitudinal edges of films 14, 15 are connected with a cord 16 between each other. The cord 16 is pulled serially via evenly arranged eyelet leads 17 along the length of edges of strips 14, 15. The upper longitudinal edge of the strip 14 is connected with an inner longitudinal edge of the mat 6 via links of the lattice 4. The upper longitudinal edge of the strip 15 is connected with the lattice 3 in the upper part of the tight chamber 2 by a cord 24.

EFFECT: increased efficiency of collection of oil products poured onto water surface.
