BACKGROUND OF THE INVENTION
This invention relates to water-wave energy converter.
Being a major factor in maintaining or improving the economy of every country of the world, energy, most parti¬ cularly the oil form, has been imposing more and more critical problems to all nations, it being a disappearing material aside from being a polutant and not available to all nations. Nuclear energy, aside from being costly and unsafe, is not also available to all nations. To ease these problems, efforts had been more exerted than ever to explore and make use of the alternative and regenerative energies that do not use the fuel oil, such as, the -wind, the solar, the ocean energy, and the municipal wastes.
Referring to Patent No. 4,160,624, dated July 20,1979 "Water Vehicle-Actuated Air Compressor and System Therefor" by Smith, the paddles, which are submerged at the bottom of the* barge, are actuated by the tilting and oscillation movements of the barge and not by the direct impact of the waves. This kind of design of an energy converter works only with the modulated water waves, so it must be placed away from rough seas and away from the beaches where the surfs stand up and break- otherwise, the whole system will be destroyed, or build the system into a very heavy out of proportion structure. This air compressor by Smith can work to some extent but without much expectation of its performance because there are glaring drawbacks and limitations such as, the following;
1. The floating barge in open sea will be tossed up and down causing vear and tear, reducing the durability and efficient of all the parts. Actually, it will require a very heavy structure of construction to withstand the stresses imparted by the big surf specially during violent weather. The anchor chain must be strong enough to hold the barge against the heavy impact of the surf on the wide side of the barge. In the same manner, the structures
SUBSTITUTESHEET holding the chain, otherwise, the whole barge in rsp torn apart into pieces. It therefore requires a very high cost of construction to withstand the forces of the waves during violent weather. This will result to a very low ratio of energy production against cost of construction and mainte- nance.
2. As per construction of the barge and the relative quantities and sizes of the paddles together with the steel compressed air tank and other machineries loaded on the barge, most of the energy brought in by the incoming water- wave will be spent splashing on the side of the barge and in tossing-up the heavy structure barge. Therefore, only a very small percentage of the energy offered by the waves is use to actuate the paddles.
3. The presented design of the paddles, the compreε- sion cylinders, and the piston, as shown in the drawings, no matter how they will be modified, as a water-wave actuated compressor is limited to a certain size or ampli¬ tude of the waves, because, if the amplitudes of the waves are relatively shorter than the length of the compression cylinder the piston does not reach the dead end of the compression cylinder resulting to a situation where the entrapped air will not be compressed far enough so it will refuse to enter the storage tank which is supposed to be in high pressure to contain plenty of energy reserved therein; and if the size or amplitude of the waves are relatively longer than the length of the compression cylinder the piston will hit the dead end of the cylinder and stops there too early. The remaining part of the long wave amplitude will be spent or destroyed needlessly pushing the already locked or dead paddles, pressing it against the limiting walls of the barge, and tends to • destroy the bearing and the connectors or the whole system, these special features of the patented design of the actuator-compression system limits the conversion of energy to a small quantity or a small percentage of the abundant energy offered by the ocean waves.
4. During calm weather when the ocean waves are small,
SUBSTITUTE SHEET the heavy barge which is designed to withstand the big εur f c will just be flattening the waves resulting to a zero efficiency, no production because there will be no oscilla¬ tion.
5. There is no plurality of storage tank to meet the 5 opportunity to store more energy.
It is therefore the primary object of this invention to provide a water-wave energy converter wherein particular attention is concentrated on the maximum harnessing of the ocean waves in the maximum efficiency and effectiveness of 0 energy convertion out of whatever size or amplitude of available water-wave that arrives at the structures to actuate the energy converter system.
It is also the objective of this invention to maximize production of consumable energy (compressed air, electricity,
15 or hydrogen gas) out of the water-wave at any weather condition, and at any location of the body of water or any part of the ocean, in the most simple and safest way, and in the least cost of construction and least cost of main¬ tenance with high durability.
20 Another object of this invention is to provide a vater- wave energy converter that will solve all of the afore¬ mentioned problems or impediments encountered preventing the commercial use of the aforementioned prior arts up to the present time. The subject energy converter is designed
•6-J to work efficiently during ordinary weather and during violent weather as well, at the lower cost of construction and maintenance, regardless of the sizes or varying amplitudes of the water waves, taking the opportunity to convert much energy during times of abundance.
30 Other objects and advantages of the present invention would become apparent upon a reading of the following detailed description taken in conjunction with the appended drawing, wherein:

Referring now to the drawing in detail and specifi¬ cally to figures 1 to 3, there is shown my present invention for a Water-Wave Energy Converter, generally designated as A,comprising a multi-stage compressor 10 and a power trans¬ fer mechanism 14 where the multi-stage compressor 10 is attached.
Said multi-stage compressor 10 comprises a plurality of adjoining chambers 100, 101, 102, 193, 115. On each chambers is provided with piston 105, valves 106, and 109, a piston rod 194 connecting all pistons, an air sealer 107 to prevent the back flow escape of compressed gas through the movement of the piston rod 104, a roller bearing 111 that supports the weight of the piston rod 104, and oil pipes 112 and 113 for oil circulation. At least one cir¬ cular type one-way valve 106 disposed on the front wall and on every common end wall of said chambers and at every piston such that said one-way valve on every piston closes during compression and opens during intake stroke and on every common end wall of said chambers open on the compre¬ ssion and closes on the intake stroke. A casing 119 is provided on one end of said chamber having an air vent 120
SUBSTITUTESHEET and an air filter 114 where fresh air enters. A delivery pipe 118 is secured on the other end of said chamber where .high pressure air exists leading to a turbine or any electrical generator.
As the piston 105 moves forward to the right all the valves 106 closes and compresses the air on its front to the right creating a partial vacuum on its rear on the left causing compressed air to be transferred to the next smaller chamber to the right at the same time with atmos¬ pheric air entering chamber 100 thru air vent 120 thru air filter 114. At the same time, as valve 109 is floating and rear if each piston will cause the oil to circulate to the top of each chamber to lubricate the piston rings, the valves, and the sealers. On the backward movement of the piston, all the valves 106 of the chamber end walls will close causing the air on the rear side of the piston to transfer to the front side of each of the pistons all the same time.
A power transfer mechanism 14 is shown in Figure 3 which transmits the energy of the waves to the multi-stage compressor 10 thru push rod 147 by mechanical means, Said power transfer mechanism 14 comprises at least two main support posts 132 wherein the multi-stage compressor 10 is rigidly attached, an impact wall 130, at least two float pipes 133 attached at the bottom of said impact wall 130. Said impact wall 130 is held by at least two pendulum beams 131 pivotally connected there to by joint 134 which enables it to bend backward by means of hydraulic control means 135 which acts as shock absorber every time an over size surf strikes the power transfer mechanism 14 specially during violent weather in order to keep it working and take advan¬ tage of the abundance of energy on those time without endangering destruction of the machine. Said hydraulic control' eans 131 consists of a hydraulic jack 135 atta¬ ched to the pendulum beams 131 and impact wall 130 and being supported to the main support post 132 by bumper 140 thru push valve 136. A pressure tank 138 being held
SUBSTITUTE SHEET to pendulum beam 131 is provided with oil line 139 to be used for hydraulic jack 135 thru control valve 137. Pendu¬ lum beam 131 is being supported to the main support posts 132 by horizontal arms 154 and 155 thru a connector box 153 pivotall connected thereto. The box connector 153 will allow the pendulum beam 131 to move up and down as it adjust to the elevation of the tides and is provided with a pneumatic clamp 141 to hold the beam 131 every time the joint 134 relaxes. A rotary switch 144 attached to a redundant bar 148 which is in turn at-tached to the hori- zontal arm 154 will relax. Clamp 141 when the pendulum beam comes to vertical position. Said box connector 153 is provided with tooth gear 142 that travels along straiσht gear 143 provided at one side of the pendulum beam 131 that holds said beam every time a surf strikes the impact vail to prevent the impact wall from rising upward due to the swell of the water waves which affect floater 133. A travelling bearing 146 one end of which is pivotally conn¬ ected to said push rod 147 and the ether end is εlidably attached to one side of the pendulum beam 131. As vave strike the power transfer mechanism 14 thru impact wall 130, it would cause the pendulum beam to move in the direction of the wave, as this happen, the travelling bearing 146 transmit a reciprocating motion to the push rod 147 which in turn operates the multi-stage compressor 10. Push valve 136 will release hydraulic fluid when it bump with bumper 140. The pressurized tank 138 will force back the oil to the hydraulic jack 135 during the return cycle of the pendulum beam. Guy wire 149 also acts as shock absorber and keeps the posts 132 in erect position. Figure 4 shows another embodiment of the invention adaptable on shallow waters or on the seashore where the sea bed acts as foundation for the support posts wherein a series of water-wave energy converter are coupled toge¬ ther to act as one machine on a coupling brace 160 with tension bar 161 holding the compressor 10. Line 162 is the water edge on the seashore and line 152 is the nose of the
SUBST/T TESHEET water wave striking the impact wall. This machine in com¬ bination with gas-turbine electric generator and electro- lize , will produce consumable energy in the form of com¬ pressed air, electricity, and hydrogen gas fuel in capsules. Figure 5 shows another embodiment of the invention wherein the whole machine of Figure 4 is floating over the deep ocean without being oscillated by the water waves 152. A long span 90% submerged plurality of superposed horizon¬ tal footing pipes 170 are disposed on opposed sides of the machine forming a thin bladed beam that easily slice thru on-rushing surfs and thru up and down motion of the waves. Said pipes 170 serves as footing for the machine and are attached to the support posts 132. The front ends of the pipe 170 is provided with a straight vertical clip 171 which has one of its sides pointed against the waves. The rear ends of the pipes 170 is provided with another clip 172 to keep the pipes in good formation acting as one strong beam. Anchor chain 185 holds each of the bottom tip of the support posts 132 with its lower end anchored to the sea bed on which the whole structure will be pivoting according to the direction of the waves. Guy wires 149 keeps the whole machine stay erect against the heavy back¬ wards push by the water waves. A flat deck barge 176 is shown attached to the clip 172 of the footing pipes 170 by the rope 186 and pivotally by the pump drive bar 188 through connecting means 187. Said bar 188 is horizontally held by piston rod 104 at its control portion pushing said rod 104 tip and down to operate small compressor 10 verti¬ cally attached to the barge as the barge floats up and down by the swell of water waves. Two storage tanks 174 and 175 are spacedly disposed at the bottom of said barge 176. Also said barge carries a gas-turbine electric generator 183, an electrolizer 184, a cabin 181 and the two compre¬ ssors 10 to compress hydrogen and air. Storage tanks 175 stores the hydrogen gas produced by electrolizer 184. Tank 174 stores compressed air from compressor 10 delivered by air hose 139.
SUBSTI UTES H An anti-oscillation resistor 207, a large wide board is attached to the rear tip of the floating pipe 170 by means-of a rigid strong pipe 216 to prevent pipe 170 from oscillating due to the action of waves is provided with upward one-way valve. Referring now to Figure 6, there is shown another embodiment of the invention wherein a fix bar 177 is dis¬ posed vertically traversing the flat deck barge 176 being held thereof by pin connector 181 and being supported be¬ low water surfaces where there is minimal movement by bo- ttom weight 178. A plurality of equidistant compressor 10 are connected to the fix bar 177 by the piston rods 117. Said compressor 10 are installed on the flat deck 176 and are supported by free revolving footing 179 so that they move vertically and horizontally according to the movements of the floating storage tanks 174 and 175 as affected by water waves. To keep the flat deck always positioned per¬ pendicular to the water waves, a caudal board 182 is atta¬ ched at the rear thereof.
Referring now to Figure 7, there is shown another embodiment of the invention wherein the fixed bar 177 is driven direct to the ocean bed and keeped rigidly by guy ropes 192 anchored to the sea bed. The flat deck 176 pivots around said bar 177 by means of universal joint 190. All compressors 10 are attached to the fix bar 177 by con- nector 193 in relation with deck 176. Connector ring 193 is loose allowing the whole flat deck 176 to move up or down the length of bar 177 to adjust with varying elevation of the tides. Piston rod 194 is provided with a hydraulic switch adjuster 189 which relaxes the piston rod every time an over sized water wave move up the air tank 174 and 175 to avoid the destruction of the compressor. Caudal board 182 keeps the flat deck in correct position in rela¬ tion with the waves.
Referring now to Figure 8, there is shown another embodiment of the invention wherein a plurality of floating air tanks 174 are εpacedly held on a strong drive bar 188
SUBSTITUTE SHEE'i positioned obliquely to the direction of the waves or even set loose along the direction of the waves. Each tank 174 carries a multi-stage compressor 100 with the piston rod 104 traversing said tanks that hold it by a connector (not shown) at the bottom of each tank to make the tank fixed in one position. As the water wave move up one tank, the corresponding piston rod moves the compression up at the same time the succeeding next time moves down on the valley of the waves moving down the compressor against the rising piston affecting the compression process on the second compression, and son on. The weight 220 hanging on the anchor rope 185 serves as shock absorber against jerk on the rope 185 due to the action of the waves on the tank. Crossed ropes 149 are provided to brace the tank to make them stay squarely in relation with the drive bars. The compressed air stored in each of the tanks 174 is delivered to the power station or the factory thru the air hose 139 which is connected to all the floating air tanks 174.
Referring now to Figures 9 and 10, there is shown another embodiment of my invention which is a water-piston compressor which produces compressed air thru the up and down movements of the water surface into the interior of a large vertically floating capsule 200 due to the aciton of the water waves. The compressor is kept afloat by ring floater 204. It is kept rigidly vertical against the ho¬ rizontal forces of the waves by sling rope 213 and by osci¬ llation resistor 207 which is rigidly supported by beam
216 at least 30 feet below the water surface. The oscilla¬ tion resistor 207 prevents the compressor from going up every time the water waves 152 come in, at the same time, sling 212 acts the same way, thereby pressing the main body 200 of the compressor against the rising water surface
217 thereby effecting the compression process. Said water-position compressor comprises a large vertically floating open-bottom capsule 200 housing a pair of opposedly disposed one-way valve 210 having float valves bells 201, 202, and 209 and cage 214 which limits the play
SUBSTITUTE SHEET of float valves balls 201 and 202. When the water sur¬ face 217 rise up into the open-bottom capsule 200, the entra-pped air of the capsule is compressed upward lifting the float valve balls and the one-way valve 210 to enter the air into the lower chamber and into the upper chamber if the water wave is big enough the make the water surface rise above the lower valves. When the water rises above any of the valves, the ball valves 201 and 202 will just float releasing the water down but closes tot rap the air when the water is gone. The valves 202 and 209 contribute to the raped entrance thru the side walls of the main body 200 to take advantage of the large available energy of the waves during violent weather. The lower float valve 201 keeps the compression process going on even during calm weather when the waves are small because the headroom of the rising water piston is made low which make it easier to push the compressed air post the lower main valve 201. Air turbine 203 supplies electricity to the warning light 213. Cage 214 limits the movement of float valves 201 and 202. Pipe 206 connected to said capsule delivers compre¬ ssed air to the power station. Weight 215 keeps the whole system to an erect station. Weight 215 keeps the whole system an erect position specially during violent weather. Structural brace 205 holes the ring floater 204 in place. The one-way valves 208 of the oscillation resistor 207 facilitate the downward movement of the system in accor¬ dance to the lowest valley of the waves to maximize the amplitude of the water pi'ston. Side valves 202 and 209 bring in new air into the chambers when the water surface 217 recedes down.
