Description

ANCHOR INTEGRATED TERMINATOR WAVE ENERGY GENERATOR DESCRIPTION
[001] Nearshore wave energy generators are capable of performing two main functions: energy generation and coastal protection. Kinetic energy from ocean waves may be extracted for electricity generation or a mechanical purpose such as seawater desalination while the conversion of energy can diminish the force of the waves, potentially reducing coastal erosion. The Anchor Integrated Terminator Wave Energy Generator is a novel nearshore wave energy generator with a self-contained mooring system that can serve both of these purposes.
[002] Wave energy generators are mechanical devices that convert the kinetic energy from the ocean's waves into more productive forms of energy, typically electricity, hydraulic pressure or pneumatic pressure. Wave energy generators can be subdivided into several categories based on their structural design and whether they are installed onshore, nearshore or offshore.
[003] When the main structure of a wave energy generator is located on land it is referred to as an 'onshore'wave energy generator. Installations in shallow water are 'nearshore' devices while 'offshore'wave energy generators are placed in deeper waters often hundreds to thousands of meters from the coast. As a wave propagates towards the coast the water becomes shallower and the energy contained within the wave decreases.
[004] With any given set of wave conditions, two factors increase the quantity of energy that can be extracted; efficiency of the energy conversion and the width of wavefront intercepted. Terminators are a type of linear wave energy generator deployed parallel to the wavefront. This orientation makes them a material efficient design as they can increase their wave energy extraction through only scaling the width of the device.
[005] Coastal protection is a method of controlling the erosion and accretion of sand and sediment along a coastline that may also provide protection from flooding. Methods of coastal protection include soft engineering and hard engineering. Soft engineering refers to the use of the natural environment to mitigate erosion through means such as beach replenishment or dune stabilisation. Hard engineering describes the use of artificial structures including seawalls and revetments to disrupt changes to the coast.
[006] Seawalls are vertical barriers placed in the path of moving water to protect beaches, cliffs or canal walls from degradation. They are often constructed from precast concrete or boulders that are buried under sand. As a wave impacts the seawall it is reflected back towards the ocean, preventing erosion behind the wall but often increasing erosion in front of it.
[007] Revetments are sloped, wave dissipating structures that also align parallel to the wavefront. They can be constructed as artificial shorelines from tetrapod shaped concrete, rocks or gravel to promote turbulence as water flows across its surface or from horizontal wooden planks with gaps that allows water to flow through the revetment. The dissipation rather than reflection of waves by revetments tends to reduce erosion behind the structure while not significantly impacting erosion rates in front of it.
[008] The Anchor Integrated Terminator Wave Energy Generator is a nearshore terminator wave energy generator that rests on the seabed under its own mass and utilises a heaving motion to extract wave energy. It is composed of 6 main components: an oceanside anchor (1), a shoreside anchor (2), struts (3), A-frame levers (4), a float (5) and a linear actuator (6). Drawing 1 depicts an isometric view of an assembled Anchor Integrated Terminator Wave Energy Generator.
[009] The Anchor Integrated Terminator Wave Energy Generator is intended to be installed in shallow, coastal water such that the side profile of the oceanside anchor (1), shoreside anchor (2) and float (5), as shown in Drawing 2 are aligned parallel to the wavefront. The float (4) will be the first component exposed to the wavefront before the waves progress towards the oceanside anchor (1) then shoreside anchor (2).
[0010] To simplify the installation and decommissioning process, the mass of the oceanside anchor (1) and shoreside anchor (2) is intended to secure the structure to the seabed as a gravity anchor to resist movement as a result of wind, wave or tidal forces. This method reduces the need for ground penetration through permanent mooring or anchors with flukes.
[011] The oceanside anchor (1) forms the central point of attachment for the Anchor Integrated Terminator Wave Energy Generator. Drawing 3 is an exploded view of the oceanside anchor (1) assembled from staggered layers of anchor blocks (7) enclosed by oceanside anchor end flanges (8) that determine the oceanside anchor's cross-sectional profile. All components are fixed together with threaded rods (9) and nuts (10).
[012] The anchor block (7) has a horizontally facing profile of a square with two sides capped with semicircles (11) and rod holes (12) positioned at the centre of the semicircle radius to facilitate the insertion of the threaded rods (9). The semicircular ends (11) of the anchor block (7) enable the modular element to be used in building a variety of profile shapes with straight and rounded edges.
[013] Drawing 4 presents an orthographic view of the anchor block (7). The anchor block (7) can be fabricated as individually cast pieces or extruded and cut to the desired width from corrosion resistant materials such as concrete to increase their longevity when submerged in seawater.
[014] The anchor block (7) can also be made hollow through injection moulding a polymer into an open block and filling the cavity with a substance denser than water before being enclosed. Drawing 5 is an exploded view of a hollow variant of the anchor block (7) comprised of a block shell (13), block end plates (14) with rod holes (12) and rod supports (15). The block fill should be an inert material such as sand or iron oxide powder to avoid environmental damage in the event of a spill.
[015] The oceanside anchor end flange (8) is a sheet or plate with rod holes (16) that align to the anchor brick rod holes (12) and threaded rods (9) to form the desired shape of the anchor segment. The oceanside anchor end flange (8) has a 90 fold (17) towards the centre of the anchor that forms a horizontal platform to mount a hinge, depicted in Drawing 1 in the form of an anchor clevis yoke (18). The anchor clevis yoke (18) is cast or machined from a single piece of metal or fabricated by welding plates together. The hole of the anchor clevis yoke is the pivot point for the A-frame lever (4) as the float (5) rises and falls with the waves. A clevis pin with a circlip or R-clip secures the lever to the joint.
[016] The cross-sectional profile of the oceanside anchor (1) functions to both lower the centre of gravity of the oceanside anchor (1) and to perform as a revetment with a negative gradient sloping down towards the ocean contributing to the dissipation of wave energy as water moves against the structure. Triangles, trapeziums and parallelograms are viable shapes to achieve this slope while the oceanside anchor (1) displayed throughout Drawings 1, 2, 3 and 10 is formed as an irregular hexagon.
[017] The total width of the oceanside anchor (1) is the product of the number of layers of anchor brick (7), the width of each layer of anchor brick (7) and the combined width of flanges within the assembly. As the ability to extract wave energy for generation and coastal protection is dependent on the width of the structure, incrementally adding layers of anchor bricks (7), also requiring increases to the length of the threaded rods (9), enables modularity of design.
[018] The shoreside anchor (2) is a polygonal subassembly positioned behind the oceanside anchor (1) so that is closer to the shore when deployed. The construction method used in the oceanside anchor (1) is also used in the shoreside anchor (2) with Drawing 6 showing an exploded view of the shoreside anchor (2) with 5 arrayed anchor blocks (7) per layer, shoreside anchor end flanges (19), threaded rods (9) and nuts (10).
[019] The shoreside anchor end flange (19) also has a 900 fold (17) towards the centre of the anchor forming a platform to mount another hinge, the linear actuator clevis joint (20) that secures the body of the linear actuator (6) to the shoreside anchor (2).
[020] The shoreside anchor (2) is attached to the oceanside anchor (1) with diagonal and horizontal struts (3) that are bolted to the threaded rods (9) to provide a rigid gravity anchor structure. The struts (3) of Drawing 1 are lengths of U-channel. Holes in the struts (3) align to the rod holes (16) on the oceanside anchor end flange (8) and shoreside anchor end flange (19).
[021] To effectively serve the function of a gravity anchor, the net density of the combined oceanside anchor (1), shoreside anchor (2) and struts (3) must be greater than that of seawater. The internal cavity between the oceanside anchor end flanges (8) and blocks (7) of the oceanside anchor (1) can be filled with ballast such as recycled concrete aggregate to add mass to the structure.
[022] Two A-frame levers (4) made of square rod provide a mechanical connection to transfer the motion of the float (5) to the linear actuators. Each A-frame lever (4) contains three linkages: an anchor clevis eye (21) to connect the lever to the anchor clevis yoke (18), a piston clevis eye (22) to connect the lever to the piston of the linear actuator (6) and a set of bolt holes (23) to enable the lever to be bolted to the float (5). Drawing 7 is an isometric view of one A-frame lever (4).
[023] Both clevis eyes (21) and (22) are made of metal plate of equal thickness to the lever and are welded in place. The anchor clevis eye (21) can be angled such that the lever, as depicted in a sectional view in Drawing 8, reaches a mechanical limit (24) by colliding with the base of the anchor clevis yoke (18) when the float rises to a defined maximum height. This limit restricts the travel of the linear actuator's piston to prevent crushing damage from occurring to the linear actuator (6) when exposed to large waves.
[024] The float (5) is the most seaward positioned component within the Anchor Integrated Terminator Wave Energy Generator. The positive buoyancy of the float (5) causes it to rise with a wave crest and fall with the wave trough to create a heaving motion. The float (5) is constructed with the same technique as the oceanside anchor (1) and shoreside anchor (2) however while the floating blocks (25) have the same profile as the anchor blocks (7) used in the oceanside anchor (1) and shoreside anchor (2), they are built hollow and watertight or of a solid material with a density lower than that of water to maintain a positive buoyant force when deployed in the ocean.
[025] Drawing 9 has an exploded view of a float (5) with layers of 8 floating bricks (25) in staggered octagonal arrays capped by float end flanges (26). Attached to the external face of the float end flange (26) is a mechanical linkage (27) for connecting the float (5) to the levers (3). The mechanical linkage (27) depicted is a square tube welded onto the float end flange (26) with holes that align to the lever bolt holes (23).
[026] The float (5) also contains internal flanges (28) placed between layers of floating blocks (25) to provide additional structural support to the assembly, particularly on wider builds. The alignment and quantity of rod holes (16) must be consistent across the float end flanges (26) and internal flanges (28). Internal flanges can also be placed within the oceanside anchor (1) and shoreside anchor (2).
[027] To maintain positive buoyancy, the float (5) must have a net density below that of seawater. The internal cavity formed between the floating bricks (25) and float end flanges (26) can be filled with objects such as sealed hollow cylinders or drums to provide additional buoyancy.
[028] The maximum wave height that can be encountered by the Anchor Integrated Terminator Wave Energy Generator before being completely submerged is equal to the distance from the seabed to the hole of the anchor clevis yoke (18) plus the distance from the hole of the anchor clevis joint yoke (18) to the furthest point of the float (5).
[029] The linear actuator (6) is a device that converts the motion of the levers (4) into a useable form of energy. As the float (5) rises with a wave crest the piston of the linear actuator (6) is depressed while the decent of the float into a wave trough extends the linear actuator (6). The linear actuator (6) can be a hydraulic cylinder to pressurise a liquid, a pneumatic cylinder to pressurise a gas or a linear electrical generator to produce an output of electrical energy.
[030] The stroke length of the linear actuator is dependent on the arc travelled by the piston clevis eye (22) on the lever (4). A longer distance between the piston clevis eye (22) and anchor clevis yoke (18) will result in a longer arc length travelled. The distance between the linear actuator clevis joint (20) and piston clevis eye (22) at maximum float (5) height, depicted in Drawing 10 and minimum float (5) height, depicted in Drawing 2, determines the minimum and maximum length of the linear actuator respectively.
[031] When the linear actuator (6) produces an output of pressurised fluid, the flow of multiple Anchor Integrated Terminator Wave Energy Generators can be combined in a wave generator farm to consolidate the number of parts such as hydraulic motors and electrical generators in a power take-off system.
[032] Lifting of the Integrated Anchor Terminator Wave Energy Generator can be performed through the use of detachable lifting lugs (29). The lifting lugs (29) are bolted to the threaded rods (9) onto the outside surfaces of the oceanside anchor end flange (8) and shoreside anchor end flange (19).The lifting lugs (29) can be fitted with shackles or directly hooked to a sling to enable a crane to raise the assembled structure. Multiple lifting lugs (29) can be attached to each flange for multi-legged slings with the mounting positions chosen to best align the crane hoist with the Integrated Anchor Terminator Wave Energy Generator's centre of gravity. Eye nuts can be fitted onto other threaded rods of the oceanside anchor (1) and shoreside anchor (2) for the attachment of taglines to manually control the alignment of the Integrated Anchor Terminator Wave Energy Generator during lifting and placement.
[033] All metal components within the Anchor Integrated Terminator Wave Energy Generator including the threaded rods (9), nuts (10), oceanside anchor end flange (8) and internal flange, shoreside anchor end flange (19) and internal flange, struts (3), A-frame lever (4), anchor clevis yoke (18), actuator clevis joint (20), float end flange (26) and lifting lugs (29) are constructed from marine-grade alloys such as 316 stainless steel or bronze and can be painted to provide additional protection against corrosion.
