Abstract

A plurality of floats in the form of panels1,2, with short axes horizontal and in line, linked by variable length units 10 having pistons and also by couplers 9, take energy from differential fluid wave motions by means of connecting cords 11 that pass over spools 12 used for power capture. The spools are linked to pumps or generators 15 with connecting shafts and gears 17.

Description
1. Floats (1), linked into lines by variable length unfts (10) take energy from differential fluid body wave motions.
2. Floats (1) are panels (2) with their weight distributed such that their narrowest axis is horizontal.
3. Units (10) connect to floats (1) at their long horizont& axis centre and at a level about which forces balance.
4. Floats (1) are metal, synthetic or timber sealed containers or solid sections, sometimes woven together.
5. Floats(1) have (heavier than the fluid) ballast (3) to keep most of their volume below the fluid surface.
6. The ballast (3) may be granules, concrete. stones, rods and/or cables, and is restrained against movement.
7. Fluid in panels (2) or tubes (4) can be displaced by gas, raising the units (10) for maintenance and/or air cooling.
8. Plates (5) of stronger material such metal or reinforced plastic are fixed by bolts through the panels (2).
9. Panels (2) have cills (6) at their lower and beams (7) at their top edges to hold containers or sections together.
10. Gills (6) and beams (7) transfer wave shear loads to panel centres, where plates (5) assist transfer to units (10).
11. Gills (6) are channels, I sections or troughs into which panels (2) are fixed and ballast (3) is placed.
12. Beams (7) support, and act as decks for maintaining or changing, parts of units (ID) atthefluid body surface.
13, Beams (7) have upstands, rails or and/or ropes along their sides and/or a textured top surface to aid man access.
14. Gills (6) and beams (7) are made of metal, reinforced plastic or treated timber with non corroding fixings.
15, Gills (6) and beams (7) are standard sections or bent sheets with punched out teeth to grip panels (2).
16. Floats (1) are made from non deteriorating materials or have preservative anti fouling surface coatings.
17. Panels (2) have solid or hollow elastic fenders (8) protecting their top corners from impact during storms.
18. Floats (1) are connected together into rows by chains, cables or stiff elastic couplers (9) that restore spacings.
19. Couplers (9) are curved or U shaped rods or tubes, clamped in sockets on cilis (6), that recover their shape.
20. Links break and disconnect units (10) overstressed by intrusion of whales or other bodies, to prevent damage.
21. Elastic material is stretched as floats (1) separate, and retracts units (10) as floats (1) move together.
22. Units (10) have pistons with rods through the cylinders that pressurise fluid in pipelines via non return valves.
23. Pistons draw fluid from the body supporting the floats (1) or return pipelines via filters and non return valves.
24. Units (10) have cords (11) between floats (I) running through scrapers or glands to remove fluid and debris.
25. Cords (11) run through eyelets or pulleys attached to floats (1) or plates (5) and go upwards.
26. Cords (II) wind onto spools (12) one for power capture, the other for adjustment, on adjacent floats (1) in the line.
27. Elastic material such as coiled springs (14) turns spools (12) to retract cords (Ii) between converging floats (1).
28. Units (10) have pumps which pressurise fluid into pipelines or electricity generators (IS) connected to cables (16).
29. Cables (16) run in the grooves between the panels (2) and the upstands of cills (6), and act as ballast (3).
30. Regulators control the pumps or generators (15) and emit signals giving data on the energy captured.
31. Spools (12) turn pump or generator (15) shafts directly, or turn gears (1 7) that then turn the shafts.
32. Reversible motors (1 8) turn spools (12) via spiralled to angled tooth gears (17) to adjust cord length/tension.
33. More powerful motors (18) can be fitted so units (10) can be shortened En sequence to generate waves.
34. Sensors transmit signals on the length, tension and angle of units (10) to show the situation of the floats (1).
35. Spools (12), springs (14), generators (15), gears (17) and motors (18) are in removable sealed casings (19).

37. Spools (12), generators (15). andtor motors (18) have quick release fixings and can be replaced individually.
36. Units (10) link floats (I) in the two outer rows to catenaries (20), so float (1) arrays can be reconfigured or moved.
39. Non generating units (21) are angled so the positions of the rows of floats (1) can be restored quickly.
40. Rows of floats (1) are aligned along the ends of the main rows to capture waves running paralleF to them.
41. Side catenaries (22) are attached to the main catenaries (20). providing some of the tension they need.
