Pumping system for use on a moveable flood control barrier

摘要

A dual pumping system for use on a movable flood control barrier structure to allow the structure to be swung into the opening of a waterway and sunk to prevent flooding during storms and then floated and swung out of the waterway after the storm is disclosed. A buoyant generally rectangular barge may be employed as the movable flood control barrier. A centrifugal pumping system pumps water into compartments within the barrier structure so it sinks to the bottom of the waterway while the same pumping system pumps water back to the waterway to float the structure. A hydraulic pumping system operates hydraulic winches to move the structure into and out of the channel using cables. The two pumping systems are capable of operating both the water pumping system and hydraulic winch system simultaneously or independently with a single engine.

主权项

1. A vessel at a first position in a waterway having a hull and a deck including:
an engine mounted on said deck, said engine driving a first system and a second system, said first system including said engine connected to a speed reducer, said speed reducer connected to a power take off clutch, said power take off clutch connected to a drive coupling, and a centrifugal pump to fill and empty at least one container located in said hull, said second system further including said engine connected to an electromagnetic clutch, said electromagnetic clutch connected to a hydraulic pump, said hydraulic pump powering at least one winch, said at least one winch connected to a cable, said cable further connected to a position proximal the waterway, whereby said hydraulic pump causes said winch to rotate, pulling said cable, causing said vessel to move from the first position to a second position, the second position perpendicular to the flow of the waterway, where said centrifugal pump floods said at least one container, causing said vessel to sink, blocking the waterway.
