Abstract
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.
Claims (15)
1. A wave powered peristaltic hose pump containing a reciprocating, low-stretch peristaltic hose functioning both as a pump component and a flexible, fixed length link; opposing first and second buoyant members attached to each end of the peristaltic hose such that the attachment means do not arrest or significantly restrict fluid flow into and out of the peristaltic hose; a compression block incorporating at least two freely rotating compression rollers between which the peristaltic hose is drawn back and forth by the opposing buoyant members such that the proximity of the compression rollers adjacent cylindrical surfaces temporarily occludes the peristaltic hose; an anchoring means to which the block assembly is attached such that it provides a relatively immovable reaction point in relation to the moving buoyant members and; a flow control means which alternately allows fluid to be forced out of and replenishment fluid to be drawn into the peristaltic hose as it moves back and forth through the point of occlusion.
2. A device as described in Claim 1 wherein one of the compression rollers also functions as a sheave or what is more commonly called a pulley, about which the peristaltic hose rotates as it is drawn back and forth.
3. A device as described in Claims 1 and 2 wherein occlusion of the peristaltic hose occurs solely as a result of the compressive force being applied to that portion of the peristaltic hose wall drawn against the face of a freely rotating pulley about which it rotates, to the degree that a second or plurality of cooperating compression rollers are not required to cause occlusion.
4. A device as described in Claim 3 wherein occlusion of the peristaltic hose is facilitated by the use of a polygon or rounded polygon shaped pulley rather than a round pulley, such that the compressive force being applied to that portion of the peristaltic hose wall rotating about the pulley is distributed intermittently or unevenly rather than continuously or evenly.
~. A device as described in Claims 1 to 4 wherein the peristaltic hose is supported by a flexible, low-stretch or fixed length link such as an over-braided member, or an internally or externally contiguous band or a cable; this flexible link rather than the peristaltic hose being attached to each of the buoyant members such that the tensile load caused by the opposing buoyant members is carried wholly or in large part by the flexible link rather than by the peristaltic hose.
6. A device as defined in Claim 5 wherein the peristaltic hose and flexible link are attached or bonded to each other at either a single or intermittent points in order to prevent excessive, uni-directional creep or extrusion of the peristaltic hose in relation to the flexible link, but otherwise can move independently of each other such that one will not tear or break away from the other in the event that they undergo an uneven degree of stretching, bending, twisting or excessive tensile loading, as can be the case with conventionally reinforced hoses incorporating continuously bonded or molded-in reinforcement.
7. A device as defined in Claim 5 wherein the peristaltic hose and flexible link may be continuously attached or bonded to each other such that one will not tear or break away from the other in the event that they undergo an uneven degree of stretching, bending, twisting or excessive tensile loading, as can be the case with conventionally reinforced hoses incorporating continuously bonded or molded-in reinforcement.
8. A device as described in Claims 5 to 7 wherein the flexible link, by virtue of its high tensile strength, allows for the use of otherwise unsuitable, less costly hoses including those significantly thinner walled than conventional peristaltic hoses, such that their larger inside diameters can be taken advantage of in order to increase volumetric output when maximum outside diameters may be limited by other factors.
9. A device as described in Claims 5 to 8 wherein the flexible link prevents a loss of seal and, therefore, a loss of pumping capability caused by incomplete occlusion of the peristaltic hose due to excessive reduction of the wall thickness of the peristaltic hose resulting from excessive stretching.
10. A device as described in Claims 1 to 9 wherein a second peristaltic hose or peristaltic hose and flexible link assembly, a second compression block and a second anchoring means are incorporated into the apparatus between the buoyant members;
the peristaltic hoses are attached to one another at a point between the buoyant members such that they reciprocate in tandem and; the fluids flowing within the peristaltic hoses are not combined as a result of this attachment; all with the result that the first peristaltic hose is pumping out fluid while the second one is drawing in fluid as the peristaltic hoses move in tandem in one direction and conversely, the first peristaltic hose is drawing in fluid while the second one is pumping out fluid as the peristaltic hoses move in tandem in the opposite direction.
the peristaltic hoses are attached to one another at a point between the buoyant members such that they reciprocate in tandem and; the fluids flowing within the peristaltic hoses are not combined as a result of this attachment; all with the result that the first peristaltic hose is pumping out fluid while the second one is drawing in fluid as the peristaltic hoses move in tandem in one direction and conversely, the first peristaltic hose is drawing in fluid while the second one is pumping out fluid as the peristaltic hoses move in tandem in the opposite direction.
11. A device as described in Claim 10 wherein the first and second compression blocks are replaced by first and second pulley blocks with occlusion of the peristaltic hoses being provided instead by either a single shared or a plurality of hose compression means such as compression blocks located between the pulley blocks.
12. A device as described in Claims 10 and 11 wherein the inside diameter of the two peristaltic hoses differs in order that the device can be optimized to address uneven energy levels being harvestable from the rising wave fronts and falling wave backs.
13. A device as described in Claims 1 to 12 wherein extensions are employed to add length to the peristaltic hose(s) or peristaltic hose and flexible link assembly(s) in order to adjust for seasonal changes and other varying conditions such as the depth and density of the body of fluid in which the apparatus in installed, wave height, tide range and current.
14. A device as described in Claims 1 to 13 wherein the buoyant members can be fully or partially inflated or deflated to allow for in-situ system optimization and to facilitate installation, removal and deployment.
15. A device as described in Claims 1 to 14 wherein the peristaltic hose(s) may be any hose or tube capable of returning to its natural, internally open state following occlusion or compression to the degree that it is capable of drawing fluid into itself.
