<p>The invention provides a pump assembly (1;100) which harnesses wave power to drive a pumping mechanism (6;105). The assembly (1;100) comprises a massive oscillatory member (2;104) guided for movement between an anchor (3;101) and a raft (9;112) and connected to the pumping mechanism (6;105). The anchor (3;101) includes guides (4;103) to control the movement and for the member (2;104) which is connected to the raft (9;112) by a centrally located cable. In one embodiment, the member (2;104) is cast in concrete and connected to a plurality of pumping mechanisms (6;105) which discharge into a common delivery pipe. Each pumping mechanism (6;105) includes a plurality of pumping units (13;106) having an annular resilient tubular construction, preferably a series of motor vehicle tyres (14;107). The valves for the pumping mechanisms (6;105) will preferably be simple flap valves and the vehicle tyre (14;107) pumping units (13;106) will be supported in individual guides (4;103) comprising parts of larger tyres (22;113) obtained by cutting the larger tyres (22;113) in a plane perpendicular to the tyres axis. These assemblies of unsophisticated concrete and steel structures and used tyres harness wave power to pump vast quantities of sea water which can be put to any of a number of uses.</p> |
