ABSTRACT:
A self-leveling skimmer attached to a boat is designed to remove a top surface layer of liquid while maintaining a constant position relative to the surface of the liquid layer. While maintaining a constant position relative to the top surface layer of liquid, the device provides for continuous removal of the top surface layer of liquid of a constant thickness regardless of changes in the elevation of the surface of the top liquid layer. The device includes multiple hollow bodies that rotate independently about a shaft. The shaft is situated parallel to the surface of the top liquid layer. Each hollow body has a lengthwise opening. The edge closest to the top surface layer of liquid forms a weir. The weir has a repetitive triangular or V-notch shape. A suction line extends into each hollow body so as to remove the liquid collected therein. Each hollow body is capable of rotating about the shaft. When the buoyant torque is greater than the gravitational torque, the hollow body rotates in such a manner so as to lower the weir below the surface of the top liquid layer, thus allowing the fluid to enter the hollow body. Once the gravitational torque exceeds the buoyant torque, the hollow body will then rotate in an opposite direction so as to raise the weir above the surface of the top liquid layer. The device achieves this action by providing for a pivot location of the hollow body which is offset from the longitudinal axis of the hollow body. Therefore, the position of the weir stays relatively constant in relation to the top surface layer of liquid.
