DEVICE FOR COLLECTING LIQUID PETROLEUM PRODUCTS FROM WATER SURFACE Russian patent published in 1997 - IPC

FIELD: mechanical oil-skimming equipment. SUBSTANCE: device for removing split petroleum products from surface of open water basins is made up of a floating vessel and control and pumping-out systems. Electrically-driven pump is connected through two-position valve with petroleum product pipeline or with casual water pipeline. Floating vessel has a body with inner chamber and fluid divider with cover which are tightened together by central bolt. Located on body bottom is plate in the form of disk with single-side hub. Mounted on plate for possible vertical displacement are two regulating floats carrying circular magnets. Mounted on plates where floats are contacting are holding members made of magnetic material and sensor generating signals for control unit about presence of certain amount of petroleum products or water in inner chamber. Located inside body is floating intake pipe connection coupled to plate by chain link restricting its upward movement to certain limit. Floating vessel is kept afloat by external pontoons secured underneath and provided with possibility for gradual regulation of their vertical position relative to vessel body. EFFECT: high efficiency. 4 cl, 6 dwg
