Abstract (en)
[origin: CA2722528A1] A wave-powered peristaltic hose pump, typically installed in a body of fluid upon which waves occur. It is characterized by a peristaltic hose which is reciprocally drawn through one or more anchored compression pulley blocks by opposing buoyant members reacting to undulating wave action. Occlusion of the hose by the compression pulley block causes a reciprocating inflow and outflow of water which is converted to a one¬ way outflow by a set of valves. When tensile loads are beyond the capabilities of the the peristaltic hose itself, it is installed within a low-stretch, flexible support means linked to the opposing buoyant members in a manner which minimizes tensile loading of the peristaltic hose. The apparatus is employed to deliver a flow of pressurized seawater to power driven devices or processes such as but not limited to desalinators, electricity generators, hydraulic motors and hydrogen fuel generators.
