Definitions
- the present invention relates generally to electricity generation. More particularly, the present invention relates to converting water wave energy into electrical power.
- Electricity generation is the process of generating electric power from sources of primary energy, such as through electromechanical generators driven by heat engines fueled by combustion or nuclear fission, and/or through other means such as harnessing the kinetic energy of flowing water and wind.
- Other energy sources include solar photovoltaics and geothermal power.
- electrical power is typically generated at a power plant and delivered to individual homes, businesses or other recipients through an electrical distribution grid.
- people who live on islands in oceans or lakes large enough to have reasonably constant wind, or shorelines, or similar areas may not have consistent or reliable access to an electrical grid, and it may be desirable to seek alternative methods to provide electrical power for their households.
- One such alternative is to install a device in a nearby body of water with wave action in order to convert the kinetic wave energy into electrical power.
- the present invention seeks to provide a wave energy converter (WEC) system that meets the following criteria: 1) is not expensive, 2) can operate as well in deep as shallow water, 3) can be fully water and wind proofed so it can be sustained untended in water for long periods of time, 4) can operate well in all wind conditions, and 5) can use leverage to reduce the force necessary to generate electricity. No previous art seems to meet all these conditions. Features 2, 3 and 4 are absolutely necessary for any WEC system that is actually useable; conditions 1 and 5 are highly desirable. Unless a WEC design contains solutions to these problems, it is not likely to be of practical use.
- the present invention seeks to address these problems by presenting a moveable raft with a long lever arm and a float at its opposite end.
- the float is stationary, connected by anchor line to the sea bed, which may be far below sea level.
- the WEC machinery on the raft is hermetically enclosed in a capsule, making it weather proof. No opening is required to allow the lever to move up and down, as is typical in prior lever-based art.
- the raft is designed to look like a weather vane, so it always faces into the wind.
- the float at the end of the lever remains stationary at trough water level, but rising waves raise the raft and WEC generating electricity.
- Construction of the raft and WEC can be low tech. Materials for the raft suitable for generating electric for 5 families are estimated to be relatively low-cost and suitable for application with individual households.
- anchor line—based prior art simply does not work in windy conditions. These anchor line designs depend on gears or pulleys moving back and forth along the anchor line due to rising and falling waves. With wind, the gear driven WEC mechanism can be blown to the far end of the anchor line and held there by the wind as waves rise and fall; hence, there is no movement by the mechanism along the anchor line, and therefore no electricity generated. This is a flaw in its design which renders it unsuitable for practical applications. Both types of prior art seem to provide exposure to weather and salt water which could impede the WEC's functioning.
- the current invention uses an anchor line to provide a cost-effective way of connecting the moving platform supporting the WEC device to the stationary sea bed, no matter how deep the water is, without the limitations found in prior art using anchor lines.
- the relative motion is then harvested to produce electricity.
- the WEC is hermetically sealed, providing full weather protection to the WEC machinery, located inside the sealed capsule.
- the new invention is furthermore unaffected by wind.

- the present invention is a mounting system for a wave energy converter (WEC) that is inexpensive, is able to operate in any water depth, can be fully water and windproof in order to operate untended for long periods of time, can operate in all wind conditions, and can use leverage to reduce force necessary to generate electricity.
- WEC wave energy converter
- a wave energy converter utilizes the reciprocating rotational motion of a device placed in water to generate electricity.
- the reciprocating rotational motion is caused by repeated wave action which drives an electrical generator in order to produce electricity.
- An enclosure containing the WEC device for converting waves to electricity is connected to a mount on a platform floating at water level and rotates on an axle connecting it to the mount.
- a float arm is attached to the enclosure at one end, and the stationary float at the other, is lifted repeatedly at the enclosure end by waves, producing rotational motion of the enclosure around the axle connecting it to the platform mount.
- This axle, to which an input pulley is connected does not turn as the enclosure revolves around it.
- a system of pulleys and/or gears attached by axle to the enclosure turn because of their motion around the belt or chain connecting them to the stationary input axle.
- This transfers power through one or more systems of pulleys to an output axle connected to the generator.
- the system of pulleys multiplies the input rotation through mechanical advantage into a much faster angular speed at the output axle. It is contemplated that where applicable, references to pulleys or gears may be understood to be interchangeable or may be utilized in conjunction with each other, in that the pulleys and/or gears serve the same purpose of producing a mechanical advantage in multiplying an input rotation at the float arm into a faster output rotation at the generator.
- the pulleys and/or gears may be connected to each other through any applicable means, such as, but not limited to, flat belts, V-belts, other belt types, roller chains, or other types of chains.
- a reversible ratchet gear maintains influence of the float arm on the system on both the upstroke and downstroke.
- a flywheel may be used to store rotational energy to maintain a stable rotational rate.
- the present invention comprises a floatable platform 1 , an enclosure 3 , an enclosure support axle 4 , a float arm 5 , a float 6 , a wave energy converter mechanism 7 , and an electrical generator 8 .
- the float arm 5 comprises a proximal end 51 and a distal end 52 .
- the enclosure support axle 4 is mounted to the floatable platform 1 , wherein the enclosure support axle 4 is affixed in place relative to the floatable platform 1 and does not rotate relative to the floatable platform 1 .
- the enclosure support axle 4 traverses through the enclosure 3 , and the enclosure 3 is rotatably engaged with the enclosure support axle 4 , wherein the enclosure 3 is free to rotate about the enclosure support axle 4 .
- the preferred embodiment of the present invention further comprises an anchor line 9 connected to the float 6 at one end and to the sea bed at the other end of the anchor line 9 .
- the floatable platform 1 is maintained within an acceptable positioning range atop the water.
- the anchor line 9 will remain taut against wave and wind forces, so that the float 6 remains stationary at trough water level.
- FIGS. 3-4 illustrate the rotation of the enclosure 3 due to the float 6 and anchor line 9 as waves crest and fall while the float 6 stays taut on the anchor line 9 .
- the wave energy converter mechanism 7 and the electrical generator 8 are positioned within the enclosure 3 .
- the wave energy converter mechanism 7 comprises a stationary input pulley 71 , at least one pulley system 72 , and a generator output pulley 73 , wherein each of the at least one pulley system 72 comprises a large input pulley 74 and a small output pulley 75 .
- the large input pulley 74 is torsionally coupled to the small output pulley 75 by a belt 76 for each of the at least one pulley system 72 .
- the stationary input pulley 71 is mounted within the enclosure 3 , such that the stationary input pulley 71 is restrained from rotation relative to the enclosure 3 .
- the float 6 is connected to the distal end 52 of the float arm 5 , and the proximal end 51 of the float arm 5 is connected to the enclosure 3 .
- the stationary input pulley 71 is torsionally and mechanically coupled to the generator output pulley 73 through the at least one pulley system 72 , and the generator output pulley 73 is rotatably coupled to the electrical generator 8 .
- the wave energy converter mechanism 7 and the electrical generator 8 are both hermetically sealed within the enclosure 3 , making the wave energy converter mechanism 7 and the electrical generator 8 weatherproof and waterproof against various environmental hazards which may potentially damage the present invention.
- unusual weather conditions may cause unusually high wave peaks to “swamp” the floatable platform 1 and WEC.
- the present invention to be of practical use, it is important that it be capable of withstanding submersion without damage.
- the float arm 5 is oriented perpendicular to the enclosure support axle 4 , such that the float arm 5 is oriented along a longitudinal direction, and wherein the enclosure support axle 4 is oriented along a lateral direction, thus facilitating efficient transferal of force from the float arm 5 to the wave energy converter mechanism 7 .
- Some embodiments may further comprise a counterweight being connected within the enclosure 3 adjacent to the proximal end 51 of the float arm 5 , though the location of the counterweight may vary as desired.
- the floatable platform 1 further comprises at least one enclosure mount 2 .
- the enclosure support axle 4 therefore, is mounted to the at least one enclosure mount 2 , and the at least one enclosure mount 2 is positioned laterally adjacent to the enclosure 3 .
- the at least one enclosure mount 2 comprises a first enclosure mount 21 and a second enclosure mount 22 , with the enclosure 3 being positioned between the first enclosure mount 21 and the second enclosure mount 22 .
- the enclosure support axle 4 is thus connected between the first enclosure mount 21 and the second enclosure mount 22 while traversing through the enclosure 3 , such that the enclosure 3 is supported between the first enclosure mount 21 and the second enclosure mount 22 by the enclosure support axle 4 .
- the enclosure 3 is thus able to rotate about the enclosure support axle 4 .
- the stationary input pulley 71 of the wave energy converter mechanism 7 is axially fixed to the enclosure support axle 4 within the enclosure 3 . Therefore, the stationary input pulley 71 is restrained from rotation relative to the enclosure support axle 4 . As the enclosure 3 is allowed to rotate about the enclosure support axle 4 , the enclosure 3 thus furthermore rotates relative to the stationary input pulley 71 .
- Each pulley of the at least one pulley system 72 , as well as the generator output pulley 73 is fixed by an axle to the interior of the enclosure 3 , thus being translationally fixed within the enclosure 3 but allowed to rotate.
- the pulleys of the at least one pulley system 72 and the generator output pulley 73 also rotate in an arc about the enclosure support axle 4 and the stationary input pulley 71 , rotating the pulleys of the at least one pulley system 72 and the generator output pulley 73 relative to each other.
- the stationary input pulley 71 is connected through the at least one pulley system 72 to the generator output pulley 73 , the rotation of the least one pulley system and the generator output pulley 73 about the stationary input pulley 71 causes the pulleys of the at least one pulley system 72 , and thus the generator output pulley 73 , to rotate relative to each other.
- the floatable platform 1 further comprises a deck 11 and an opening 12 .
- the at least one enclosure mount 2 is connected atop the deck 11 , and the opening 12 traverses through the deck 11 .
- the float arm 5 and the float 6 are aligned within the opening 12 , wherein the float arm 5 and the float 6 are free to traverse into the opening 12 .
- the opening 12 should traverse vertically through the entirety of the floatable platform 1 , enabling the float 6 to contact the water upon which the floatable platform 1 is floated.
- the float 6 is generally constrained to the surface of the water, while the floatable platform 1 rises and falls according to any wave action.
- the preferred embodiment of the present invention further comprises a generator axle 100
- the at least one pulley system 72 further comprises an intermediate axle 77 and an intermediate pulley 78
- the intermediate pulley 78 is axially fixed to the intermediate axle 77 .
- the generator axle 100 is axially fixed to the electrical generator 8 and the generator output pulley 73
- the intermediate pulley 78 is torsionally coupled to the generator output pulley 73 through a belt 76 or chain.
- the at least one pulley system 72 comprises an arbitrary pulley system 710 and an adjacent pulley system 720 .
- the small output pulley 75 of the arbitrary pulley system 710 is axially fixed to the large input pulley 74 of the adjacent pulley system 720 .
- the rotational speed of the small output pulley 75 of the adjacent pulley system 720 in relation to the small output pulley 75 of the arbitrary pulley system 710 is multiplied by the ratio of the large input pulley 74 of the adjacent pulley system 720 to the small output pulley 75 of the arbitrary pulley system 710 .
- the at least one pulley system 72 may further comprise a first pulley system 730 and a last pulley system 740 .
- the large input pulley 74 of the first pulley system 730 is the stationary input pulley 71
- the small output pulley 75 of the last pulley system 740 is the generator output pulley 73 .
- rotational speed is transferred from the stationary input pulley 71 , through any intermediary pulley systems of the at least one pulley system 72 , and ultimately to the generator output pulley 73 , being multiplied through pulley ratios along the way so that, for example, in a single 45-degree rotation of the enclosure 3 , the generator output pulley 73 , and thus the generator axle 100 connected to the electrical generator 8 , is rotated 25 times, generating 25 rotations worth of electricity through the electrical generator 8 .
- the small output pulley 75 of the first pulley system 730 is axially fixed to the large input pulley 74 of the last pulley system 740 .
- the small output pulley 75 of the first pulley system 730 and the large input pulley 74 of the last pulley system 740 are axially fixed to an intermediate axle 77 , wherein the intermediate axle 77 is rotationally connected to the housing.
- the small output pulley 75 of the first pulley system 730 and the large input pulley 74 of the last pulley system 740 are translationally fixed in place relative to the enclosure 3 , but are free to rotate on the intermediate axle 77 .
- the stationary input pulley 71 is the large input pulley 74 of the first pulley system 730 .
- the stationary input pulley 71 is torsionally connected to the small output pulley 75 of the first pulley system 730 by a chain or belt 76 .
- the ratio of the diameters of the stationary input pulley 71 to the small output pulley 75 may be, but is not limited to, ten to one.
- the small output pulley 75 of the first pulley system 730 transfers its angular velocity to the intermediate axle 77 , and thus the large input pulley 74 of the last pulley system 740 .
- the large input pulley 74 of the last pulley system 740 then transfers its tangential velocity to the small output pulley 75 of the last pulley system 740 , which is the generator output pulley 73 .
- the ratio of the diameters of the large input pulley 74 of the last pulley system 740 to the generator output pulley 73 may be, but is not limited to, ten to one.
- the input rotation is multiplied by 100.
- the float arm 5 causes the enclosure 3 to rotate about the enclosure support axle 4 .
- the small output pulley 75 of the first pulley system 730 rotates in an arc about the stationary input pulley 71 , wherein the stationary input pulley 71 in the current example is the large input pulley 74 of the first pulley system 730 .
- the small output pulley 75 of the first pulley system 730 is torsionally connected to the stationary input pulley 71 by a fixed belt 76 or chain, the arced rotation of the small output pulley 75 of the first pulley about the stationary input pulley 71 causes the small output pulley 75 of the first pulley system 730 to rotate. This rotation is thus transferred to the large input pulley 74 of the second pulley system, being axially fixed to the small output pulley 75 of the first pulley system 730 , and further multiplied from the large input pulley 74 of the second pulley system to the small output pulley 75 of the second pulley system, which is also the generator output pulley 73 , thus generating electricity.
- Some embodiments of the present invention may further comprise a flywheel 110 , as can be seen in FIG. 8 .
- the flywheel 110 serves to maintain a consistent rotational speed delivery of the wave energy converter mechanism 7 to the electrical generator 8 through potentially inconsistent wave action.
- the flywheel 110 may be rotationally connected to one of the at least one pulley system 72 , or the flywheel 110 may be rotationally connected to the generator axle 100 , or anywhere else in the system the flywheel 110 may function optimally.
- the present invention may comprise a reversible ratchet gear 120 operatively engaged with one of the at least one pulley system 72 .
- the reversible ratchet gear 120 may be connected with the wave energy converter mechanism 7 in any applicable configuration to enable adequate rotational force applied to the system to maintain the generator axle 100 spinning in the proper direction.
- the reversible ratchet gear 120 is connected to the large input pulley 74 of the last pulley system 740 or second pulley system, or to the intermediate pulley 78 , or to the intermediate axle 77 , as appropriate.
- the floatable platform 1 further comprises a keel 130 , and/or rudder connected to the deck 11 opposite the enclosure 3 mount, and the keel 130 should be laterally aligned with the float arm 5 .
- the purpose of the keel 130 is to maintain a proper orientation of the floatable platform 1 in relation to the wave action and/or wind forces to ensure optimal orientation of the float arm 5 .
- the keel 130 may act as a brace or a stop which may prevent the float arm 5 from rotating downwards more than a certain amount, such as, but not limited to, 90 degrees downward from horizontal, as can be seen in FIG. 4 .
- some embodiments of the present invention may further comprise at least one weathervane fin 140 connected to the deck 11 of the floatable platform 1 , being oriented along the longitudinal direction, and distributed symmetrically about a longitudinal centerline of the deck 11 .

A wave energy converter deep sea mounting system consists of a floatable platform, an enclosure, a wave energy converter mechanism, a generator, a float arm, and a float. The enclosure is mounted atop the floatable platform by an enclosure support axle, about which the enclosure can rotate. The wave energy converter mechanism and the electrical generator are mounted within the enclosure. The float arm is connected between the enclosure and a stationary float, and as the floatable platform rises and falls due to wave action, the enclosure is thus rotated. The wave energy converter mechanism has a stationary input pulley connected through at least one pulley system to a generator output pulley, multiplying input rotations from the float arm action to the electrical generator in order to generate electricity. As the enclosure rotates about the stationary input pulley, the remaining pulleys are forced to spin through rotation about the stationary input pulley.
Description
- The present invention relates generally to electricity generation. More particularly, the present invention relates to converting water wave energy into electrical power.
- Electricity generation is the process of generating electric power from sources of primary energy, such as through electromechanical generators driven by heat engines fueled by combustion or nuclear fission, and/or through other means such as harnessing the kinetic energy of flowing water and wind. Other energy sources include solar photovoltaics and geothermal power. In most modern developed areas, electrical power is typically generated at a power plant and delivered to individual homes, businesses or other recipients through an electrical distribution grid. However, people who live on islands in oceans or lakes large enough to have reasonably constant wind, or shorelines, or similar areas may not have consistent or reliable access to an electrical grid, and it may be desirable to seek alternative methods to provide electrical power for their households. One such alternative is to install a device in a nearby body of water with wave action in order to convert the kinetic wave energy into electrical power.
- The present invention seeks to provide a wave energy converter (WEC) system that meets the following criteria: 1) is not expensive, 2) can operate as well in deep as shallow water, 3) can be fully water and wind proofed so it can be sustained untended in water for long periods of time, 4) can operate well in all wind conditions, and 5) can use leverage to reduce the force necessary to generate electricity. No previous art seems to meet all these conditions.
Features conditions - The present invention seeks to address these problems by presenting a moveable raft with a long lever arm and a float at its opposite end. The float is stationary, connected by anchor line to the sea bed, which may be far below sea level. As the raft bobs up and down, it moves the lever at the raft end, though the float end stays stationary. This movement turns gears or pulleys which operate a generator, generating electricity. The WEC machinery on the raft is hermetically enclosed in a capsule, making it weather proof. No opening is required to allow the lever to move up and down, as is typical in prior lever-based art. The raft is designed to look like a weather vane, so it always faces into the wind. Wind or no wind, the float at the end of the lever remains stationary at trough water level, but rising waves raise the raft and WEC generating electricity. Construction of the raft and WEC can be low tech. Materials for the raft suitable for generating electric for 5 families are estimated to be relatively low-cost and suitable for application with individual households.
- Prior art in which the platform and/or WEC is anchored using a post—based system (the “oil rig” anchoring system) does not allow WEC usage in deep water, except at exorbitant cost, affordable only by large communities already most likely to have electricity. The other alternative, anchor line—based prior art, simply does not work in windy conditions. These anchor line designs depend on gears or pulleys moving back and forth along the anchor line due to rising and falling waves. With wind, the gear driven WEC mechanism can be blown to the far end of the anchor line and held there by the wind as waves rise and fall; hence, there is no movement by the mechanism along the anchor line, and therefore no electricity generated. This is a flaw in its design which renders it unsuitable for practical applications. Both types of prior art seem to provide exposure to weather and salt water which could impede the WEC's functioning.
- The current invention uses an anchor line to provide a cost-effective way of connecting the moving platform supporting the WEC device to the stationary sea bed, no matter how deep the water is, without the limitations found in prior art using anchor lines. The relative motion is then harvested to produce electricity. The WEC is hermetically sealed, providing full weather protection to the WEC machinery, located inside the sealed capsule. The new invention is furthermore unaffected by wind.

The present invention is to be described in detail and is provided in a manner that establishes a thorough understanding of the present invention. There may be aspects of the present invention that may be practiced or utilized without the implementation of some features as they are described. It should be understood that some details have not been described in detail in order to not unnecessarily obscure focus of the invention.

- The present invention is a mounting system for a wave energy converter (WEC) that is inexpensive, is able to operate in any water depth, can be fully water and windproof in order to operate untended for long periods of time, can operate in all wind conditions, and can use leverage to reduce force necessary to generate electricity.
- For the purposes of the present disclosure, a wave energy converter (WEC) utilizes the reciprocating rotational motion of a device placed in water to generate electricity. The reciprocating rotational motion is caused by repeated wave action which drives an electrical generator in order to produce electricity. An enclosure containing the WEC device for converting waves to electricity is connected to a mount on a platform floating at water level and rotates on an axle connecting it to the mount. A float arm is attached to the enclosure at one end, and the stationary float at the other, is lifted repeatedly at the enclosure end by waves, producing rotational motion of the enclosure around the axle connecting it to the platform mount. This axle, to which an input pulley is connected, does not turn as the enclosure revolves around it. A system of pulleys and/or gears attached by axle to the enclosure, turn because of their motion around the belt or chain connecting them to the stationary input axle. This transfers power through one or more systems of pulleys to an output axle connected to the generator. The system of pulleys multiplies the input rotation through mechanical advantage into a much faster angular speed at the output axle. It is contemplated that where applicable, references to pulleys or gears may be understood to be interchangeable or may be utilized in conjunction with each other, in that the pulleys and/or gears serve the same purpose of producing a mechanical advantage in multiplying an input rotation at the float arm into a faster output rotation at the generator. The pulleys and/or gears may be connected to each other through any applicable means, such as, but not limited to, flat belts, V-belts, other belt types, roller chains, or other types of chains. A reversible ratchet gear maintains influence of the float arm on the system on both the upstroke and downstroke. A flywheel may be used to store rotational energy to maintain a stable rotational rate.
- Referring to
FIGS. 1-2 , in general, the present invention comprises afloatable platform 1, anenclosure 3, anenclosure support axle 4, afloat arm 5, afloat 6, a waveenergy converter mechanism 7, and anelectrical generator 8. - The
float arm 5 comprises aproximal end 51 and adistal end 52. Theenclosure support axle 4 is mounted to thefloatable platform 1, wherein theenclosure support axle 4 is affixed in place relative to thefloatable platform 1 and does not rotate relative to thefloatable platform 1. Theenclosure support axle 4 traverses through theenclosure 3, and theenclosure 3 is rotatably engaged with theenclosure support axle 4, wherein theenclosure 3 is free to rotate about theenclosure support axle 4. - The preferred embodiment of the present invention further comprises an
anchor line 9 connected to thefloat 6 at one end and to the sea bed at the other end of theanchor line 9. Thus, thefloatable platform 1 is maintained within an acceptable positioning range atop the water. Preferably, theanchor line 9 will remain taut against wave and wind forces, so that thefloat 6 remains stationary at trough water level.FIGS. 3-4 illustrate the rotation of theenclosure 3 due to thefloat 6 andanchor line 9 as waves crest and fall while thefloat 6 stays taut on theanchor line 9. - The wave
energy converter mechanism 7 and theelectrical generator 8 are positioned within theenclosure 3. Referring toFIGS. 5-6 , the waveenergy converter mechanism 7 comprises astationary input pulley 71, at least onepulley system 72, and agenerator output pulley 73, wherein each of the at least onepulley system 72 comprises alarge input pulley 74 and asmall output pulley 75. Thelarge input pulley 74 is torsionally coupled to thesmall output pulley 75 by abelt 76 for each of the at least onepulley system 72. - The
stationary input pulley 71 is mounted within theenclosure 3, such that thestationary input pulley 71 is restrained from rotation relative to theenclosure 3. Thefloat 6 is connected to thedistal end 52 of thefloat arm 5, and theproximal end 51 of thefloat arm 5 is connected to theenclosure 3. Thestationary input pulley 71 is torsionally and mechanically coupled to thegenerator output pulley 73 through the at least onepulley system 72, and thegenerator output pulley 73 is rotatably coupled to theelectrical generator 8. - In the preferred embodiment of the present invention, the wave
energy converter mechanism 7 and theelectrical generator 8 are both hermetically sealed within theenclosure 3, making the waveenergy converter mechanism 7 and theelectrical generator 8 weatherproof and waterproof against various environmental hazards which may potentially damage the present invention. For example, unusual weather conditions may cause unusually high wave peaks to “swamp” thefloatable platform 1 and WEC. For the present invention to be of practical use, it is important that it be capable of withstanding submersion without damage. - Furthermore, the
float arm 5 is oriented perpendicular to theenclosure support axle 4, such that thefloat arm 5 is oriented along a longitudinal direction, and wherein theenclosure support axle 4 is oriented along a lateral direction, thus facilitating efficient transferal of force from thefloat arm 5 to the waveenergy converter mechanism 7. Some embodiments may further comprise a counterweight being connected within theenclosure 3 adjacent to theproximal end 51 of thefloat arm 5, though the location of the counterweight may vary as desired. - In some embodiments, the
floatable platform 1 further comprises at least oneenclosure mount 2. Theenclosure support axle 4, therefore, is mounted to the at least oneenclosure mount 2, and the at least oneenclosure mount 2 is positioned laterally adjacent to theenclosure 3. - More specifically, in some embodiments, the at least one
enclosure mount 2 comprises afirst enclosure mount 21 and asecond enclosure mount 22, with theenclosure 3 being positioned between thefirst enclosure mount 21 and thesecond enclosure mount 22. Theenclosure support axle 4 is thus connected between thefirst enclosure mount 21 and thesecond enclosure mount 22 while traversing through theenclosure 3, such that theenclosure 3 is supported between thefirst enclosure mount 21 and thesecond enclosure mount 22 by theenclosure support axle 4. Theenclosure 3 is thus able to rotate about theenclosure support axle 4. - Furthermore, the
stationary input pulley 71 of the waveenergy converter mechanism 7 is axially fixed to theenclosure support axle 4 within theenclosure 3. Therefore, thestationary input pulley 71 is restrained from rotation relative to theenclosure support axle 4. As theenclosure 3 is allowed to rotate about theenclosure support axle 4, theenclosure 3 thus furthermore rotates relative to thestationary input pulley 71. Each pulley of the at least onepulley system 72, as well as thegenerator output pulley 73, is fixed by an axle to the interior of theenclosure 3, thus being translationally fixed within theenclosure 3 but allowed to rotate. Hence, as theenclosure 3 rotates about theenclosure support axle 4 anchoring the waveenergy converter mechanism 7 to thefloatable platform 1, the pulleys of the at least onepulley system 72 and thegenerator output pulley 73 also rotate in an arc about theenclosure support axle 4 and thestationary input pulley 71, rotating the pulleys of the at least onepulley system 72 and thegenerator output pulley 73 relative to each other. - Since the
stationary input pulley 71 is connected through the at least onepulley system 72 to thegenerator output pulley 73, the rotation of the least one pulley system and thegenerator output pulley 73 about thestationary input pulley 71 causes the pulleys of the at least onepulley system 72, and thus thegenerator output pulley 73, to rotate relative to each other. - In some embodiments, the
floatable platform 1 further comprises adeck 11 and anopening 12. The at least oneenclosure mount 2 is connected atop thedeck 11, and theopening 12 traverses through thedeck 11. Thefloat arm 5 and thefloat 6 are aligned within theopening 12, wherein thefloat arm 5 and thefloat 6 are free to traverse into theopening 12. Theopening 12 should traverse vertically through the entirety of thefloatable platform 1, enabling thefloat 6 to contact the water upon which thefloatable platform 1 is floated. Thus, thefloat 6 is generally constrained to the surface of the water, while thefloatable platform 1 rises and falls according to any wave action. - Referring to
FIG. 7 , the preferred embodiment of the present invention further comprises agenerator axle 100, while the at least onepulley system 72 further comprises anintermediate axle 77 and anintermediate pulley 78. Theintermediate pulley 78 is axially fixed to theintermediate axle 77. Thegenerator axle 100 is axially fixed to theelectrical generator 8 and thegenerator output pulley 73, and theintermediate pulley 78 is torsionally coupled to thegenerator output pulley 73 through abelt 76 or chain. - Referring to
FIG. 8 , in some embodiments, the at least onepulley system 72 comprises anarbitrary pulley system 710 and anadjacent pulley system 720. Thesmall output pulley 75 of thearbitrary pulley system 710 is axially fixed to thelarge input pulley 74 of theadjacent pulley system 720. Thus, the rotational speed of thesmall output pulley 75 of theadjacent pulley system 720 in relation to thesmall output pulley 75 of thearbitrary pulley system 710 is multiplied by the ratio of thelarge input pulley 74 of theadjacent pulley system 720 to thesmall output pulley 75 of thearbitrary pulley system 710. - Referring to
FIG. 9 , the at least onepulley system 72 may further comprise afirst pulley system 730 and alast pulley system 740. In some embodiments, thelarge input pulley 74 of thefirst pulley system 730 is thestationary input pulley 71, and thesmall output pulley 75 of thelast pulley system 740 is thegenerator output pulley 73. Thus, rotational speed is transferred from thestationary input pulley 71, through any intermediary pulley systems of the at least onepulley system 72, and ultimately to thegenerator output pulley 73, being multiplied through pulley ratios along the way so that, for example, in a single 45-degree rotation of theenclosure 3, thegenerator output pulley 73, and thus thegenerator axle 100 connected to theelectrical generator 8, is rotated 25 times, generating 25 rotations worth of electricity through theelectrical generator 8. - In some embodiments, the
small output pulley 75 of thefirst pulley system 730 is axially fixed to thelarge input pulley 74 of thelast pulley system 740. In some embodiments, thesmall output pulley 75 of thefirst pulley system 730 and thelarge input pulley 74 of thelast pulley system 740 are axially fixed to anintermediate axle 77, wherein theintermediate axle 77 is rotationally connected to the housing. Thus, thesmall output pulley 75 of thefirst pulley system 730 and thelarge input pulley 74 of thelast pulley system 740 are translationally fixed in place relative to theenclosure 3, but are free to rotate on theintermediate axle 77. - Thus, in one preferred embodiment, presented herein as a non-limiting example, the
stationary input pulley 71 is thelarge input pulley 74 of thefirst pulley system 730. Thestationary input pulley 71 is torsionally connected to thesmall output pulley 75 of thefirst pulley system 730 by a chain orbelt 76. The ratio of the diameters of thestationary input pulley 71 to thesmall output pulley 75 may be, but is not limited to, ten to one. Thesmall output pulley 75 of thefirst pulley system 730 transfers its angular velocity to theintermediate axle 77, and thus thelarge input pulley 74 of thelast pulley system 740. Thelarge input pulley 74 of thelast pulley system 740 then transfers its tangential velocity to thesmall output pulley 75 of thelast pulley system 740, which is thegenerator output pulley 73. Again, the ratio of the diameters of thelarge input pulley 74 of thelast pulley system 740 to thegenerator output pulley 73 may be, but is not limited to, ten to one. Thus, with two pulley systems with a 10:1 ratio connecting thestationary input pulley 71 to thegenerator output pulley 73, the input rotation is multiplied by 100. - Furthermore, as the
floatable platform 1 rises and sinks relative to thefloat 6 due to wave action, thefloat arm 5 causes theenclosure 3 to rotate about theenclosure support axle 4. Thesmall output pulley 75 of thefirst pulley system 730 rotates in an arc about thestationary input pulley 71, wherein thestationary input pulley 71 in the current example is thelarge input pulley 74 of thefirst pulley system 730. Since thesmall output pulley 75 of thefirst pulley system 730 is torsionally connected to thestationary input pulley 71 by a fixedbelt 76 or chain, the arced rotation of thesmall output pulley 75 of the first pulley about thestationary input pulley 71 causes thesmall output pulley 75 of thefirst pulley system 730 to rotate. This rotation is thus transferred to thelarge input pulley 74 of the second pulley system, being axially fixed to thesmall output pulley 75 of thefirst pulley system 730, and further multiplied from thelarge input pulley 74 of the second pulley system to thesmall output pulley 75 of the second pulley system, which is also thegenerator output pulley 73, thus generating electricity. - Some embodiments of the present invention may further comprise a
flywheel 110, as can be seen inFIG. 8 . Theflywheel 110 serves to maintain a consistent rotational speed delivery of the waveenergy converter mechanism 7 to theelectrical generator 8 through potentially inconsistent wave action. Theflywheel 110 may be rotationally connected to one of the at least onepulley system 72, or theflywheel 110 may be rotationally connected to thegenerator axle 100, or anywhere else in the system theflywheel 110 may function optimally. - Furthermore, as illustrated in
FIG. 8 , the present invention may comprise areversible ratchet gear 120 operatively engaged with one of the at least onepulley system 72. Thereversible ratchet gear 120 may be connected with the waveenergy converter mechanism 7 in any applicable configuration to enable adequate rotational force applied to the system to maintain thegenerator axle 100 spinning in the proper direction. In some embodiments, thereversible ratchet gear 120 is connected to thelarge input pulley 74 of thelast pulley system 740 or second pulley system, or to theintermediate pulley 78, or to theintermediate axle 77, as appropriate. - Preferably, the
floatable platform 1 further comprises akeel 130, and/or rudder connected to thedeck 11 opposite theenclosure 3 mount, and thekeel 130 should be laterally aligned with thefloat arm 5. The purpose of thekeel 130 is to maintain a proper orientation of thefloatable platform 1 in relation to the wave action and/or wind forces to ensure optimal orientation of thefloat arm 5. Furthermore, thekeel 130 may act as a brace or a stop which may prevent thefloat arm 5 from rotating downwards more than a certain amount, such as, but not limited to, 90 degrees downward from horizontal, as can be seen inFIG. 4 . - Moreover, referring to
FIG. 10 , some embodiments of the present invention may further comprise at least oneweathervane fin 140 connected to thedeck 11 of thefloatable platform 1, being oriented along the longitudinal direction, and distributed symmetrically about a longitudinal centerline of thedeck 11. The at least oneweathervane fin 140 acts to keep thefloatable platform 1 oriented into any wind forces to which thefloatable platform 1 may be subjected. In some embodiments, the at least oneenclosure mount 2 may double as the at least oneweathervane fin 140. In some embodiments, the at least oneweathervane fin 140 comprises afirst weathervane fin 142 and a second weathervane fin 144, corresponding to thefirst enclosure mount 22 and thesecond enclosure 3 mount. In some embodiments, the at least oneweathervane fin 140 may be a separate component or a plurality of separate components from the at least oneenclosure mount 2. - Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
