ABSTRACT:
A dynamic breakwater system pumps water from a body of water in response to wave action or underwater currents. A submerged stationary base is fixed to a solid subsurface. A breakwater protrudes upwardly through the surface of the water. Wheels support the breakwater for displacement on the base along a generally horizontal displacement axis. Springs acting against opposing sides of the breakwater urge it to a rest position between two horizontally extreme positions, and wave action and underwater currents against either side of the breakwater produce a reciprocating movement of the breakwater along its displacement axis. A pump pumps water in response to the reciprocating movement. The pump has a large piston spaced from the pump housing by roller assemblies. A door permits access to the pump interior for removal of debris or for repair, and a locking mechanism fixes the breakwater to the base to arrest pumping action for such purposes. Brush assemblies attached to the breakwater sweep debris from the base in response to the reciprocating motion ensuring that the breakwater continues to displace.
