  • Patent number: 6117336
    Abstract: The helix boom removes floating objects from a waterway by transporting them to the waterway side for containment and subsequent removal. Lateral transport across the waterway width is accomplished by the rotation of the buoyant boom transversing the waterway. Energy from the moving water causes the rotation of the floating boom. A continuous narrow helically shaped fin is affixed to the cylindrical surface of the boom. The water flow impacting the boom and helix causes the apparatus to rotate. Floating objects are impeded by the cylindrical boom. The rotating helix contains the floatables within the fins, causing the translational movement of the floatables across the boom face to the waterway side where the floatables may be deposited into a collection bin. Multiple booms may be utilized down stream for redundancy. An individual boom may be comprised of small segments connected together on a center hub.
