OIL GATHERING DEVICE Russian patent published in 1999 - IPC

FIELD: gathering petroleum products from water surface. SUBSTANCE: oil gathering device includes oil receiver connected with pipe line through bellows, two supporting floats for connecting bridge. Arranged between supporting floats are two working floats with equal specific gravities. They are interconnected by means of lever due to contact coupling and ballast weight fitted on end of lever. Second end of lever holds oil receiver whose inlet section is adjusted relative to surface of water and remains constant at minimum distance from water when thickness of petroleum product film changes, thus making it possible to drain petroleum products to oil receiver without water. Lever fulcrum is immovable relative to water surface; it lies on hinge axis. EFFECT: enhanced efficiency of removal of petroleum products from water surface.. 2 cl, 2 dwg
