ABSTRACT:
A device for cleaning liquid surfaces to remove a pollutant therefrom. The device comprises a barrier adapted to float on the surface of the liquid. The barrier comprises two diverging wing portions. Inlet means are provided and are adapted to receive the polluted material prior to passing the polluted material to a recovery apparatus. The device further comprises only hitching means adapted to maintain each of the wings spaced from one another at one of their ends while the barrier is being towed. Each of the wing portions of the barrier comprises a wing rope adapted to at least partially float on the liquid surface. The barrier further comprises a tow rope arranged between each of the wing ropes which is adapted to pull the recovery apparatus thereby exerting a tension on each of the wing ropes while maintaining each of the wing ropes such that they do not substantially curve in the horizontal plane relative to the surface while nevertheless allowing for movement of the wing ropes in a vertical plane with respect to the surface.
