Description

Coral polyp formula wave energy acquisition device and its application

Technical field

The present invention relates to a kind of harvester of wave energy, and its application under different sea situations, belong to ocean wave energy Field.

Technical background

At present, the worldwide wave of new energy development upsurge one exceeds a wave, wherein wave energy or one is seen But eat less than favourite, main cause is that sea environment is complicated and changeable, otherwise device conversion ratio is low, or viability is not By force.

It is as follows to be summed up more representational several ways：

First, float-type：I.e. using floating body in shifting, promotion hydraulic system storage energy or the direct generation of electricity；

Second, pendulum device：Wave impact force is absorbed using rigid pendulum mass, then promotes hydraulic mechanism storage using pendulum mass Deposit energy；

Third, valve type structure：Done work using relative motion of the several separate sections of device in wave；

Fourth, pliable pressure film (gasbag-type)：I.e. using the media flow in the pressure change extruding gasbag of the heave of waves come Absorb Wave energy.

Certainly there are many modes ingenious, such as oscillaton water column type, the duck that nods (Wave Duck) etc., here not Enumerate.But there is absorption efficiency is low or complicated heavy or not corrosion resistant for the above mode and device Erosion or easily produce failure or survival ability it is not strong or to environment it is not friendly enough the shortcomings of, up to the present do not have also There is the efficient and reliable way that large-scale commercial applications are applied.

The content of the invention

The shortcomings that in order to overcome the above device, I has carried out arduous thinking；One accidental chance, Ben Ren See a report on coral reef on the net, scientific research is found to the effect that for it, and coral reef can absorb 97% wave energy：

" scientist both knows about with surfing player, and coral reef can absorb the impulsive force of wave, under making sea gentle suddenly Come.A research points out that coral reef can offset up to 97% Wave energy ... recently "

After seeing this report, I is inspired greatly：Using coral reef as fulcrum when coral polyp waves, its flexible body leads to Cross flexural deformation and act on the institutional framework of itself, and it is done work, so as to absorb Wave energy；So if we design one The similar flexible body of coral polyp of kind is waved in water so as to absorb the device of Wave energy, is not exactly very perfect Bionic Design One is ecology it is friendly, the second is the collecting efficiency of energy it is high, the third is simple in construction ...

Therefore, present invention aim to provide it is a kind of imitate it is anthozoic wave, so as to oppress " the knot of tissue of inside Structure " simultaneously does work to " institutional framework ", so as to absorb the device of Wave energy.

In order to realize such Bionic Design, the technical solution adopted in the present invention is such：

We design the flexible hollow pendulum mass that a kind of flexible body of similar coral polyp can wave in water, and to pendulum mass Play the carrier of fixation；

The pendulum mass is a kind of flexible cavity structure, and by flexible stretch-proof material manufacture, the inside is full of water or air Deng fluid media (medium)；

The carrier is also a kind of hollow structure, inside sets pressure piping and low pressure pipeline, or only sets pressure piping, so The duct end is connected with hyperbaric chamber afterwards.

Then numerous such pendulum masses are just fixed on the carrier by its end or waist array and closely connected therewith Connect, and connected in the junction of the two by two reverse check valves with the pressure piping in the carrier and low pressure pipeline； Or only a check valve is set to be connected with the pressure piping (when in carrier setting pressure piping)；

Then carrier is fixed by mooring system, and pendulum mass described in original state in pipeline with being each filled with fluid media (medium)；Entirely Device all or most is immersed (to expose the surface on only pendulum mass head) in the seawater.

So, when wave attacks, these flexible pendulum masses being fixed on carrier will wave curved using fixing end as fulcrum Song, but because its material is non-stretchable and has been filled with fluid media (medium), so its volume is forced to reduce, internal pressure increase, so as to The pressure piping that its internal fluid media (medium) is entered in carrier by check valve is extruded, thus absorbs and stores wave energy Amount；

Then after these high-pressure mediums are aggregated into hyperbaric chamber by pressure piping, it is possible to promote the hydraulic turbine or hydraulic motor To generate electricity.

When setting pressure piping with low pressure pipeline simultaneously in carrier, the medium after acting is discharged into low pressure pipeline；Work as crest Later, pendulum mass is with ripple homing, now because pendulum mass in-vivo medium flows out, body " deflated ", then pressure be reduced to outside Portion's environment hydraulic pressure is consistent (hydrostatic pressing during no wave), and the pressure that we are designed in low pressure pipeline is slightly larger than the external rings of pendulum mass Border hydraulic pressure, the fluid media (medium) in such low pressure pipeline will be flowed into the pendulum mass inner chamber of " deflated " by another check valve, make it Interior medium is returned to original full state, forms medium circulation.

When in carrier setting pressure piping (being not provided with low pressure pipeline), the medium after acting is directly discharged into sea, so Pendulum mass draws seawater from sea by check valve by the elastic-restoring force of its own and does medium afterwards, forms medium circulation；Pendulum mass Elastic-restoring force can be by setting the mode such as elastic interlayer to realize in its body wall.

Material is thus formed one kind to be circulated, and the fluid media (medium) in pendulum mass is constantly forced out, and is also constantly replenished；And it is squeezed The medium gone out is formed actual high-pressure water head in pressure piping, and just powerful energy can be formed after being aggregated into hyperbaric chamber Amount, turbine or hydraulic motor are impacted to generate electricity, certainly can also fresh water processed after supercharging.

In addition, when pendulum mass is fixed on carrier by its end, because pendulum mass head is to thinner by the distance of fixing end Long, so the compression effectiveness of volume is not fine, we can also additionally add support, be supported in the pendulum mass waist, pendulum mass Bending is waved by fulcrum of waist when waving, the compression effectiveness of volume can be more preferable.

In this design, the swing mode of pendulum mass can be attributed to it is existing it is theoretical in pendulum-type structure, but with existing pendulum Formula structure is different；What existing pendulum-type structure utilized is that rigid pendulum mass absorbs wave energy, then recycles rigid pendulum mass to promote hydraulic pressure Mechanism stores energy, it is necessary to Liang Ge mechanisms convert twice, therefore complicated and heavy；And this structure is put using flexible hollow Body, inside be full of fluid media (medium), using fixing end are that fulcrum waves bending during work, produce volume and compress, extruding interior media, suction Receive Water wave energy；Zhi Xuyige mechanisms one-off just completes the absorption and storage of energy simultaneously, eliminates the hydraulic pressure of complexity System, pendulum-type energy-absorbing is set to become very succinct efficient, cost is greatly reduced；Material is flexible slim and graceful, the capacity of anti-storm of device Also greatly improve；And the flexible pendulum mass of the present invention, during " deflated " is waved, environment hydrostatic can also do work to it, so It can absorb ripples kinetic energy and potential energy simultaneously, it is possible to and say and existing pendulum-type structure is essentially different, pendulum device Schematic diagram refers to Figure 12 a.

This design also has similar with the Wave energy converter of another existing pressure flexible film (gasbag-type, water-bag-type) Place, the flexible pendulum mass of this programme can also regard a kind of pressure flexible film as, but this pressure membrane is by existing bag formula Planar structure, which is entered, turns to monomer structure, using fixing end as fulcrum during work, becomes a self-acting in the swing rod (pendulum of itself Plate), torque is produced by waving bending, and then internal stress and pressure are produced, interior media is extruded, absorbs ripples kinetic energy, more What is utilized is pendulum-type principle more；And what existing balloon-type device utilized is then that ripples static pressure directly produces pressure with dynamic pressure to air bag By force, lack a process around branch spot wobble, that is, lack the conversion of one of torque；Flexible pendulum mass its track during swing Inswept volume, it is more much greater than the change of its own volume, so the present invention can amplify ripples impulse force by principle of moments Effect, and then produce the internal pressure bigger than the external pressure (including dynamic pressure and static pressure) that it is subject to.

Meanwhile the distance that the stress surface of pendulum mass moves under force, also than balloon-type device stress surface in power The lower mobile distance of effect is much bigger, therefore the ability of its absorption kinetic energy of wave is stronger, so here it is of the invention and existing gas The maximum difference of bellows device.

Gasbag-type (flexible membrane) device refers to United States Patent (USP), title：Water wave energy conversion Device using flexible membranes, the patent No. (United States Patent)：4164838 August 14,1979；And another United States Patent (USP), title：ENERGY CONVERSION DEVICE, application number (Application)： The A1 August 4,2011 of US 20110185721.

As another technical scheme of present inventive concept, we can also utilize the liquid metal in flexible pendulum mass pressing body Magnetic fluid generates electricity：Main carrier or support, the high pressure chest and liquid metal magnetic that fixation is played including pendulum mass, to pendulum mass Fluid power-generation system；

The pendulum mass is a kind of flexible cavity structure, by flexible stretch-proof material manufacture, inner filling water or air Or their mixing, and be fixed on by its end or waist on the carrier or support；

The carrier or support are fixed on seabed or other offshore platforms；

The high pressure chest is with pendulum mass close to arrangement, and built with gases at high pressure, pressure is about that pendulum mass produces maximum pressure A quarter plays elastic-restoring force to half or so；

The liquid metal magnetohydrodynamic generation system includes a soft capsule of dumbbell shaped, built with accounting for one half volume Liquid metal magnetohydrodynamic；One end of the soft capsule of dumbbell shaped is placed within pendulum mass, and one end is placed in the high pressure close to arrangement with pendulum mass Intracavitary；

Then just four sides surrounds for permanent magnet the two poles of the earth and positive and negative plate electrode, is arranged symmetrically in " handle " of the soft capsule of dumbbell shaped Place, form power channel.

Whole device all or most is immersed (to expose the surface only yaw part) in the seawater, so, works as wave To attack, the pendulum mass will wave bending by fulcrum of fixing end, and volume is forced to reduce, and internal pressure increase, then promote and put The soft intracapsular liquid metal magnetohydrodynamic of dumbbell shaped in the inner flows to high pressure chest one end outside pendulum mass；

After crest, pressure is disappeared in pendulum mass, and then the gas in high pressure chest is just oppressed disposed within soft intracapsular Liquid metal magnetohydrodynamic flows to pendulum mass one end, and pendulum mass is returned to original full state.

Then, as pendulum mass constantly waves, liquid metal magnetohydrodynamic constantly moves reciprocatingly at the both ends of the soft capsule of dumbbell shaped, In the presence of permanent magnet, so as to produce electric current in two electrode loops, then control centre's rectifying and pressure-regulating output is pooled to surely Determine electric power.

The advantages of this design, without medium circulation, need to only produce the pressure of change in pendulum mass.

As another technical scheme of present inventive concept, we can also utilize the piezoelectric element in flexible pendulum mass pressing body To generate electricity, support, the piezoelectric element of fixation are mainly played including pendulum mass, to pendulum mass；

The pendulum mass is a kind of flexible cavity structure, is made up of flexible stretch-proof material, and inside is full of air, and passes through Its end and waist are fixed on the bracket；

The support is fixed on seabed or other offshore platforms；

The pendulum mass body wall is provided with interlayer space, and the piezoelectric element is placed in the interlayer space；

Whole device all or most is immersed (to expose the surface only yaw part) in the seawater, is attacked when wave, The pendulum mass will wave bending by fulcrum of fixing end, so as to which the piezoelectric element being opposite in pendulum mass body wall interlayer space produces Pressure, so as to produce piezoelectric voltage, pass through the electrode output current being placed on piezoelectric element；Then by it is a series of series connection, In parallel, voltage regulating rectifier, export stable power.

The beneficial effects of the invention are as follows：By Bionic Design, swinging type wave energy device is softly changed, simplify；Without rigidity Wobble plate, weight mitigate significantly, and the requirement to structural strength is greatly reduced；Completed using the change of flexible pendulum mass volume to inside The compression of medium or element, thus without complicated hydraulic system, cost substantially reduces and efficiency accordingly improves；Tough structure can Deformation, capacity of anti-storm greatly enhance；Whole absorbing mechanism is in addition to flexible cavity body and check valve, without other motion portions Part, without frictional dissipation, substantially without maintenance, it will not also produce noise；Efficiency high is truly realized, environment-friendly, simple warp Ji, viability are strong.

And because the pendulum mass of the present invention is flexible pendulum mass, so being especially suitable for being arranged on the carrier of tubular structure, make load Body can turn into the storage area of energy, and and can be integrally formed the mechanical support of structure, make whole device it is compact, it is economical, adapt to Property is strong.In addition, the carrier of tubular structure can be together in series, being so suitable for along the coastline completely arrangement, (necessary navigation is logical Except road), so marine site utilization rate reaches highest, the efficiency of device is indirectly also just improved, while also play breakwater Effect.

Meanwhile the carrier of tubular structure is also very suitable for being together in parallel, bent structure is formed, turns into ocean development such as sea The multifunctional platform of wind energy, solar energy；And because sea changed condition is variable, wave energy is extremely unstable, wave energy and sea The combination complementation of wind energy and solar energy is also very important, thus present invention also offers the present apparatus and wind energy on the sea and too Sun can combine the example to generate electricity, and they share mechanics rock-steady structure and transmission system, improve the stability of transmission of electricity and overall warp Ji property.

In addition, the application present invention also offers this wave energy apparatus on ocean automation net cage, because wave energy fills It is inconvenient away from continent, electric energy output to put；It is also inconvenient for its power supply and net cage is also away from continent, so the two is combined, mutually It is interdependent, it is a kind of inevitable application.The present apparatus shares mechanics rock-steady structure with net cage, is provided for the automation electrical equipment of net cage Electric energy.

Embodiment

The several preferred embodiments of the present invention are further illustrated below in conjunction with the accompanying drawings, but the structure of the present invention not only limits In following embodiment.Embodiment 1：

Fig. 1 a are referred to, are the internal structure schematic diagrams of the present apparatus, pendulum mass 1 is cylindrical in figure, passes through its end array Connect therewith in the surface of carrier 4 and closely；Pendulum mass 1 is a kind of flexible cavity structure, is made by flexible stretch-proof material, internal Full of fluid media (medium) 2；The carrier 4 and a kind of hollow structure, are designed to pipe-like, are provided with pressure piping 5 and low pressure in it Pipeline 7, and connected respectively by reverse check valve 3 and check valve 8 with the inner chamber of pendulum mass 1；Carrier 4 has three rows in figure, by framed bent Connector 11 connect it is integral, and by drag-line 16 and seabed spud pile 12 anchoring fix, pendulum mass and pipeline described in original state Fluid media (medium) 2 is inside each filled with, whole device largely suspends in the seawater, and sea is exposed in the only part of yaw 9.

Its 3 dimensional drawing refers to Fig. 1 c, and the duct-like row of carrier 4 three is placed side by side in figure, passes through framed bent connector 11 Connection, generally forms a kind of bent structure, and it is stable (specific row is depending on specific sea situation) to be advantageous to overall structure；It is and many More pendulum masses 1 is with regard to array on this special carrier framed bent.(note：The rectangular cross-section of carrier 4 in Fig. 1 a, scheme after optimized The section of carrier 4 in 1c is circle)

So, when wave attacks, these internal flexible pendulum masses full of fluid media (medium) will wave with ripple, such as Fig. 1 b institutes Show：Because the lower end of pendulum mass 1 is fixed, so be forced to wave bending by fulcrum of fixing end, become a self-acting in The swing rod of itself, external diameter tension, internal diameter are pressurized, occured bending and deformation；It is situated between because pendulum mass material is non-stretchable and has been filled with fluid Matter, therefore its volume is forced to reduce, and internal pressure increase, is flowed into so as to extrude the medium of inside by check valve 3 in carrier 4 Pressure piping 5, thus absorb and store energy.

Refer to Fig. 1 c：So, the same pendulum mass of numerous coral polyps constantly waves with ripple, the high-pressure fluid warp squeezed out Pressure piping 5 and flexible duct 13, which are flowed into hyperbaric chamber 14, to collect, and forms powerful energy, promotes turbine or hydraulic motor rotary It is dynamic to generate electricity；Then the medium after doing work is discharged into low-pressure chamber 6, then is flowed into through flexible duct 13 in the low pressure pipeline 7 in carrier 4.

Refer to Fig. 1 b：After crest, pendulum mass 1 will be returned to original erectility with ripple, at this moment due to pendulum mass 1 Interior fluid is not full, and body is deflated, and pressure is reduced to (hydrostatic pressing during no wave) consistent with external environment condition hydraulic pressure；And we Design low pressure pipeline 7 in pressure be slightly larger than ambient water pressure, typically be advisable more than 0.001~0.01MPa (equivalent to The pressure of 0.1~1 meter of head), with can to the timely water-filling of pendulum mass and paying for energy is as far as possible few for principle；Then low pressure pipeline Fluid media (medium) in 7 will flow into the inner chamber of pendulum mass 1 by check valve 8, the medium in it is returned to original full state, shape Into medium circulation.

The circulation schematic diagram of medium refers to Fig. 1 d, and the arrow in figure represents media flow direction, Jie in figure in pendulum mass 1 Matter flows into pressure piping 5 through check valve 3, then flows into hyperbaric chamber 14, and low pressure pipeline 7 is flowed into again after the acting of electricity generation system 17, then Flowed into through check valve 8 in pendulum mass, form medium circulation.It can be seen that in figure it is a kind of closed cycle, and low-pressure chamber holds with hyperbaric chamber Long-pending size is then formulated as needed, can also be cancelled.

Its cyclic process also relates to all too many levels in terms of hydraulic conduction, for example in two sections of high-low pressure, can be set certain Pressure buffer (pressure regulation) room of quantity, to adjust the change of pressure in pressure piping.In the present embodiment, framed bent connector 11 Inner space can be designed to pressure buffer room, set passage to be communicated with pressure piping in addition；It is high pressure gas in surge chamber Body, so buoyancy and energy storage space can also be provided for overall framed bent, the in parallel of internal pipeline also may be used between carrier 4 side by side Carried out by framed bent connector 11, be not described in detail here as space is limited.

A general framed bent may be designed to it is 200~500 meters long, 10~20 meters it is a width of easily, generally, the limitation of its length Factor is mainly the tension flexural capacity of carrier material, and pipeline loss is considered；If pipeline is longer, fluid energy Loss is also bigger；But if framed bent is longer, it is possible to influence of the fluctuating to framed bent of wave is stabilized, because the crest and ripple of wave Paddy can cancel out each other to the vertical impact of framed bent, and framed bent is longer, and this neutralization effect is better；And the limiting factor of width is then The problem of being economy, original this carrier framed bent is more wide more steady, and the more absorptions to wave of pendulum mass row are more, but It is too wide too many and uneconomical, so this needs makes the arrangement of economic rationality according to material property and sea features, and The size of its power is then according to the different and different of marine site wave energy density.

In this structure, there is a single yaw 9 on the top of pendulum mass 1, exposes sea, as shown in Figure 1a；Yaw 9 can be Individually hollow solid lightweight model, its density are less than water；It can also be that flexible material makes, inside fill gases at high pressure, so that It is principle to be tried one's best when it is waved indeformable.It acts on mainly capture wave, reduces more swell damage and loses；It may also function as protection simultaneously Effect, the flexible material of pendulum mass is set to corrode from the beating of solar exposure and surface seawater；Buoyancy can also be provided simultaneously, makes pendulum mass Recover erectility after bending as far as possible, or whole device provides buoyancy.

As can be seen that pendulum mass produces torque (moment of flexure) using fixing end as fulcrum, by the bending of waving of itself, so as to produce Internal stress and pressure, it is the key entirely invented so as to extrude interior media and do work；So pendulum mass volume it is bigger, around branch Point rocking tendency is bigger, carrier is more stable, material is more non-stretchable, and energy-absorbing is more (just can not because if material is stretchable Effectively constraint is formed, interior media can not be formed and extruded)；And pendulum mass is longer in the arm of force that it is waved in face under the same terms, Caused pressure is bigger；So the shape and size of pendulum mass include the efficiency that its material will all directly affect whole device, institute With signified " pendulum mass " of the invention, its definition refers in particular to wave under wave action in water using fixing end as fulcrum Bending, so that itself becoming a swing rod for acting on itself (wobble plate), side tension, side is pressurized, and occurs bending and deformation, Volume is forced to reduce, and so as to produce internal stress and pressure, extrudes and does work so as to be produced to interior media or component, so as to have Effect absorbs the flexible hollow solid of Water wave energy；So its shape is not limited only to the cylinder of the present embodiment, can also be Other shapes, such as the wobble plate of existing pendulum device, the duck that nods (Wave Duck) shape etc., so that its wave energy absorption efficiency is maximum Change, this there will be embodiment in other embodiments.

Its absorb Water wave energy E1 number, be approximately equal to highest pressure P caused by pendulum mass and be multiplied by the fluid body being squeezed out Product V (the highest pressure P of pendulum mass determined by the pressure in pressure piping, and the pressure of pressure piping is then formulated by hyperbaric chamber), I.e.：

E₁≈PxV。

So the pressure of pressure piping is unable to Ding get Tai Gao, and can not be too low, this is relevant with the size of environment Wave energy, So the maximally effective device for absorbing wave energy will automatically adjust the strong size of high pressure intraventricular pressure according to environmental condition, it is desirably to obtain E maximum, rather than P maximum.Certainly, P is bigger, then turbine efficiency is higher, considers so need to do；General feelings Under condition, its interior pressure can be set in 0.1MPa or so (that is, 10 meters of heads), and the small region of stormy waves can suitably reduce.

The mode of regulation is exactly that hyperbaric chamber is divided into the different room of several pressure, is controlled with different water inlet switch, wind Unrestrained hour, fluid media (medium) is just transported to the relatively low room of pressure, medium is just transported to the high room of pressure when stormy waves is big, thus Energy can be obtained to greatest extent according to different unrestrained high features.

Calculating above is a kind of qualitatively rough estimation, because the change of power and volume is nonlinear, it is complicated Force analysis be not discussed in detail here.It should be noted that the pendulum mass of the present embodiment is special due to body wall material, in addition The pressure of interior media is equal everywhere, and can not provide shearing force, so being not necessarily when pendulum mass bends shown in Fig. 1 b Camber line when being bent as coral polyp, it is also possible to broken line, simply a kind of signal in figure, represent that it necessarily bent and volume contracts It is small, and this is only the core of the present invention, so " bending " that the present invention is signified, including bend and bend.

Embodiment 2：

In embodiment 1, medium is extruded out of pendulum mass, is back to again along low pressure pipeline 7 in pendulum mass after acting, so medium Circulation is completely separated with outside seawater, is a kind of closed cycle.

The benefit of this circulation is can to ignore the water quality condition in marine site, can also be applied in turbid Mare Undarum domain, but also can To make medium using fresh water, the harm to device interior is reduced.But in the case of needing to lay in a large amount of seawater, this enclosed Circulation just needs a big low-pressure chamber same with hyperbaric chamber, to continue to generate electricity in the case of without stormy waves；But this undoubtedly increases Added the cost of engineering, if so medium acting after be directly discharged into sea, then pendulum mass by the elastic-restoring force of itself from Dynamic seawater of being drawn from ambient seawater does medium, then just becomes open type without low pressure pipeline and low-pressure chamber, medium circulation Circulation.

As shown in Figure 2 a, exactly designed for open circulation.Its principle and structure are substantially the same manner as Example 1, different Place is that the low pressure pipeline 7 in original carrier 4 eliminates, and is only provided with pressure piping 5；Because what we designed is that open type is followed Ring, sea is directly discharged into after medium acting, then pendulum mass draws seawater from sea by the elastic-restoring force of itself and does medium, so Low pressure pipeline 7 is exactly unnecessary, and what it is instead of it is to install a check valve 8 in pendulum mass body wall to region be directly facing sea (unidirectional stream Enter).

In order that pendulum mass 1 has automatic elastic-restoring force, we are in the body wall sandwich establishment space 10 of pendulum mass 1, the inside Air full of certain pressure, its effect are to provide tension force；So, just there is automatic elastic restoring force after pendulum mass bending.Work as ripple After peak, erectility can just be recovered automatically by waving deflated pendulum mass 1, and is drawn seawater from sea by check valve 8 and done medium.

Fig. 2 b are similar to Fig. 2 a, and simply its elastic-restoring force is different, and we are that cylindrical pendulum mass devises an individual in figure The larger bowl-type yaw of product (or cylinder), therefore yaw can provide larger pulling force (buoyancy), will can wave deflated Pendulum mass afterwards stretches, and this power stretched can just make pendulum mass 1 draw seawater from external environment condition by check valve 8 to do medium, It is set to return to original full state, institute is just simpler than Fig. 2 a in this form, and ordinary circumstance should select such a form, The shape of certain yaw should be preferred with cylinder, as shown in Figure 4.

Certainly there are other many methods, for example directly add elastic wire in pendulum mass wall, pendulum mass wall is had in itself Elastic-restoring force etc., the present invention are not limited only to this embodiment；It is internal because the core of the present invention is to use flexible pendulum mass Full of fluid media (medium), bending is waved by fulcrum of fixing end, so as to produce volume compression, so as to extrude interior media and do Work(, so as to absorb Water wave energy；So how medium circulates, how pendulum mass supplements medium, is not the main points of the present invention, existing There are many similar structures to imitate in reality, do not enumerate here.

The benefit of this design is that the intermediate links of medium simplify, and hyperbaric chamber is just directly replaced with elevated reservoir, can be with The water amount of power generating of several days is stored, but this design requires high for sea water quality.

Embodiment 3：

In embodiment 1, carrier framed bent is arranged in parallel with seashore, and the benefit being arranged so as to is to make full use of the face in marine site Product, except reserving navigation channel, profit can be intercepted close to arrangement (subsection interleaving parallel arrangement), all waves between framed bent With.But framed bent meets ripple direction narrower width when being arranged in parallel, framed bent can be caused unstable, easily rocked under wave stroke, damaged Disability amount.

So we can also allow the vertical seashore of carrier framed bent to be arranged, as shown in Figure 3：Its internal principle is with structure with implementing Example 1 is identical, and carrier (pipeline) 4 is combined into bent structure by framed bent connector 11, is four rows in figure, vertical seashore arrangement, and one As with wide 10 meters or so, long 100~200 meters are advisable that (in order to reduce installation difficulty and leakage, carrier is preferably an elongated pipe Road, contacted without being segmented, or reduce joint as far as possible).

Medium is summarized in power compartment 19 by us in figure, and power compartment 19 is directly installed on the centre position on framed bent, its The interior installation equipment such as hydraulic motor and generator, and land is delivered the power to by cable 20.So, due to framed bent both sides by To the impact of wave be the same, therefore will not rock, while meet wave impact power and also alleviate significantly, make device capacity of anti-storm Greatly enhance.But shortcoming is to need to leave larger spacing between framed bent, coastline can not completely be utilized, and the impulsive force of wave subtracts It is small, it is insufficient to the utilization rate of wave, it is adapted to the king-sized marine site of stormy waves in this arrangement.

Its power compartment 19 can be also placed on sea bed certainly, pass through flexible duct and the pipeline communication of carrier inside；And anchor Pool device then directly throws several anchor cans, in order to which picture has succinctly only drawn a spud pile 12 in figure, by drag-line 16 with Carrier 4 is connected, but this be it is inadequate, need to suitable spacing increase anchor chain quantity, depending on specific sea situation, with guarantee through By billow push-and-pull and the stable operation of device energy is criterion, being typically arranged symmetrically with 30 meters or so of spacing both sides is advisable.

Embodiment 4：

Fig. 4 is another the pendulum mass appearance forrns figure and spread pattern figure of the present invention：Its internal principle is with structure with implementing Example 1 or 2 is identical, and simply the geometry of pendulum mass changes, and becomes short and thick；Yaw 9 is also changed into a cylindrical shape；Its row simultaneously Row mode also has optimization, and in this arrangement mode, pendulum mass 1 is arranged symmetrically at the position up and down of first row carrier 4, is so designed Benefit is to improve the wave slope product of device, absorbs wave energy to greatest extent；The stability of device, anti-locking apparatus are also enhanced simultaneously It is overall in the seawater significantly to rock；Because we are it is desirable that pendulum mass rocks, and non-carrier is rocked.

Embodiment 5：

Fig. 5 is another pendulum mass spread pattern figure of the present invention, and its internal principle and structure are same as Example 1.It is different , because the wave energy density of different waters differs greatly, the possible wave energy very little in some marine sites, but wind energy and sunlight fill Foot, institute in this form in, in order that device has the benefit of commercialized running, so selection and solar energy and wind-power electricity generation phase With reference to mode, therefore pendulum mass 1 is arranged to the lower section of carrier 4, and blower fan and solar cell 18 are then installed in the top of carrier 4, 15 be blower fan post in figure, and shaped upper part is unrelated with core of the present invention, therefore does not draw.In this design, medium be air or The mixing of the two, pendulum in-vivo medium circulates in compared with hyperbar all the time, to form buoyancy.

The benefit of this design is that solar energy, wind energy and wave energy form complementation, improves the continuation of electric power, and device Utilization rate, certainly, in the embodiment of the above, as long as device is reinforced, device is had enough intensity, while it is wide to widen framed bent Degree；Or framed bent is arranged with polygonal in form, device is had enough stability, can reach thereon install additional blower fan and The purpose of solar cell.Utilization for ocean energy, it will be a development trend that this various energy resources, which combine complementary mode,.

Embodiment 6：

In embodiment above, the stereochemical structure of pendulum mass is cylindrical, but this shape is obviously unfavorable for intercepting and inhaling The kinetic energy of ripples is received, because its wave slope is arc, ripples is easily caused and is shunted to both sides；Should so effectively intercepting shape It is that wave slope is pulled into very wide tabular, such as wobble plate, the duck that also nods (Wave Duck) etc. of existing pendulum device, nod duck Device refers to Figure 12 b.

Fig. 6 a are referred to, are the graphics of the embodiment of the present invention 6, its internal principle and structure are substantially the same manner as Example 1, Unlike, the wave slope of pendulum mass is drawn very wide very wide by we in this design, and original cylinder is widened and is changed into rectangular Body (tabular), only because the present invention pendulum mass using flexible material, so the level cross-sectionn of pendulum mass will remain this Rectangle, must just have internal lacing wire to carry out drawknot on short side direction could maintain, and otherwise will become round under the pressure of fluid Shape, the effect of volume compression is not had, so its surface has to turn into corrugated in the presence of lacing wire, its internal structure please Referring to Fig. 6 b, 23 be lacing wire in figure.

So optimize after, add single pendulum mass wave slope product, reduce pendulum mass number, play one optimization structure with Propose efficient effect.Yaw 9 have also been made very big change simultaneously, the shape for duck (the Wave Duck) that be close to nod, so Be advantageous to receive ripples momentum, reduce and get over swell damage mistake.In addition, positioned at the pendulum mass end of carrier bottom, pendulum pin 22 is also set up, with pendulum Head shapes are similar, and its density is equal or slightly larger than water.The row of carrier 4 is depending on specific sea situation, in the big marine site of wave, heel row Pendulum mass can also as front row arrangement symmetrical above and below.

And wave is small and marine site that Development volue is not very big, we then reduce the row of carrier, refer to Fig. 6 b, in figure We also hang up rack etting below carrier framed bent, make net cage, and 31 be net cage in figure, to adapt to the spy of carrier framed bent Sign, net cage have made "convex" shaped shape, and the electric driving force equipment of power compartment and net cage is then installed on carrier framed bent, such as certainly Dynamic device for feeding fish bait, camera, automatic sedimentation floating body (not shown) etc., the electric power that then wave energy apparatus is sent is just directly for net cage Electrical equipment uses, and to improve the comprehensive benefit of wave-activated power generation, the poor and weak marine site of wave resource is also had its existing value.

We also further optimize in Fig. 6 b, pendulum mass is had an angle to lean forward, the benefit of this design is can be same When receive the kinetic energy of ripples both horizontally and vertically, improve absorption efficiency.Compared with cylindrical pendulum mass, tabular pendulum mass efficiency can carry It is high, it should to be a kind of very excellent form, but cylindric pendulum mass also has the advantage of oneself：Exactly no matter how wave direction becomes Change, be just as cylinder, and tabular then has optimized incidence.So the pendulum mass of cylindric (or ellipticity) is more suitable for It is arranged in the marine site away from seashore；And tabular pendulum mass is then more suitable for being arranged in Nearshore Shallow Sea, because the ripples of Nearshore Shallow Sea are basic All it is vertical coastline, direction change is little.

Embodiment 7：

Embodiment above, mainly stresses the absorption to the horizontal kinetic energy of wave, such case is adapted to shallow sea translatory wave.And If condition changes, for the marine site based on surging, this pendulum mass close to vertical display cannot be to the vertical kinetic energy of wave Effectively intercept, so need to make the appropriate adjustments.It is the graphics and internal structure schematic diagram of the present embodiment as shown in Fig. 7 a, 7b, its Internal principle and structure are substantially the same manner as Example 1, and simply specifically we put the level of pendulum mass 1, and carrier 4 is then fixed on pendulum Above the waist of body, fulcrum is formed.So, to be attacked when surging, pendulum mass 1 is moved up by upward thrust, but due to carrier 4 very Heavy and pind down by drag-line, so it can turn into a fulcrum of pendulum mass waist, pendulum mass both ends be forced upwardly bending, so this The acting principle of kind form is still identical with embodiment above, and simply current pendulum mass is changed into teetering from vacillating now to the left, now to the right.

In order that overall structure is stable in figure, we connect two row's carriers by the frame 30 that spreads out, the middle then company of setting Logical pipeline and power compartment 19, so, whole platform can serve as the pedestal of solar energy or blower fan, and the present embodiment is then at it Rack etting is hung up below, is combined with net cage, and 31 be net cage in figure, and 32 be Autoamtic bait putting machine；It can be seen that this wave energy apparatus Tubular carrier formed platform be well suited for being combined with net cage really, in the marine site of the small and suitable cage culture of stormy waves, wave energy Device provides electric energy for the automation equipment of net cage, and they are a pair of the best partners.

Its internal structural map refers to Fig. 7 b, and the waist of an elongated pendulum mass 1 is distinguished by two check valves in figure Connected with the pressure piping 5 in carrier 4 and low pressure pipeline 7, pendulum mass 1 is lying on ripples, and the yaw 9 at both ends is made upward Ox horn shape, to intercept wave, suitable space is also left in the pipeline 5 and 7 in carrier, to form buoyancy.Can certainly Float tube additionally is added, to combine with specific design, seldom state as space is limited；Solar energy has also additionally been added in figure Battery 18, to increase the stability of its power supply.

In this form, carrier framed bent is that vertical wave direction is put, and many such units, which are together in series, meets ripple one Word is arranged, and is adapted to the medium marine site less than normal of wave in this form；And in the very big marine site of wave, because this form can not Wave energy can just be fully absorbed by the row's pendulum mass of a row two, so in the big marine site of wave, then be adapted to do growth serpentine, it is suitable Wave direction arrangement, as shown in Figure 7 c, its length typically at 100~200 meters, spacing between carrier then substantially with length phase Deng.

Above in several embodiments, there is a problem deserving of attention to be, due to the continuous tide bulge and fall of seawater, to avoid Device is flooded completely at the incoming tide, so drag-line is longer and leaves certain leeway, to ensure that device can be with tidal level fluctuation.But this Sampling device equally also can waste energy with wave fluctuation, if so the drag-line perpendicular to seabed is set in addition, with one Monitoring device is also feasible plan so as to automatically adjust guy cable length from motion tracking sea level height, and this sampling device only will rise with tidal level Fall, without with wave fluctuation.

As can be seen that more than the present invention in several embodiments, pendulum mass is responsible for the collection and conversion of energy, and carrier is then responsible for Transport, the storage of integrally-built stabilization and energy.Their relation just as coral polyp is as the relation of coral reef, mutually according to Deposit, form a brand-new ecosystem, there is no any influence on fish；Fish can swim in its lower section to be plowed, and can also pass through load Shuttle up and down in the groined type space of body framed bent.

Except fish culture in net pen, we can also do other maricultures and cultivation, such as black pearl culture, sea-tangle cultivation Deng accomplishing the maximization of the utilization of resources.If framed bent is designed to sufficiently solid, it can also turn into Oversea wind and photovoltaic generation Floating body platform.So the present invention has sizable advantage using the flexible pendulum mass of small size, because its own is not only It is only simple, efficiently, viability it is strong, and be adapted to be arranged on the carrier of pipeline configuration, and the carrier of pipeline configuration then can be with shape Into bent structure, and framed bent can then turn into the versatile platform of ocean development, while can also form artificial marine habitat, form one Individual new micro-ecological environment, the place inhabited is provided for fish, not only be make use of Wave energy, has also been afforested ocean.

Embodiment 8：

In embodiment above, device is all floatation type, but is exactly that whole device has different journeys the shortcomings that floatation type The fluctuating of degree is rocked, and causes energy loss, if so can securely fix the device of the present invention, efficiency can be carried further It is high.

As shown in Figure 8 a, it is the graphics of the embodiment of the present invention 8, its internal principle and structure are substantially the same manner as Example 7, Simply current pendulum mass is disposed vertically, while carrier is not floated but got stuck.21 be pile in figure；24 be connection Part.We beat firm basis from seabed, then erect a reinforced concrete pile 21 at a certain distance, then certain length Carrier 4 is serially connected by connector 24, and connector 24 is then stuck in the line of rabbet joint of pile 21, can only be fluctuated with tidal level And can not translate and rock, so that carrier 4 keeps stable.

We further simplify carrier framed bent and pendulum mass quantity in figure, while pendulum mass is designed as into an elongated entirety, on Portion is provided with yaw 9, and bottom is provided with pendulum pin 22, then connects fixation with the side of carrier 4 at its waist；Its internal structure is as schemed Shown in 8b, it can be readily seen that, when pendulum mass 1 is by wave stroke, its waist is held out by the waist by carrier 4, forms fulcrum, then Occur bending and deformation, compressing interior media enter pressure piping 5, so this structural form more simplified than embodiment above, It is more efficient.We have also been devised the net cage 31 being fixed on carrier 4 in Fig. 8 b, its with carrier 4 for floating body and anchor structure, simultaneously Wave energy can also be utilized to provide energy for electrical equipments such as its Autoamtic bait putting machines, this situation is adapted to wave medium less than normal and cultivated Marine site with favourable conditions.

And for the very abundant marine site of Wave energy, then net cage can not be set, and once be intercepted not enough, then we Can design it is secondary, intercept three times, the row of increase carrier (pipeline) 4 is similar with Fig. 6 a, is by the connection of framed bent connector Can.

This fixed structure using concrete pile as support, an also use is exactly that can be used as Oversea wind power generation Base for post, though therefore erect concrete pile 21 cost it is high, income can be bigger.It is expected that the shallow sea of 10~30 meters or so of the depth of water compared with Ideal, and the device of floatation type can then be adapted to deeper marine site, and the height of whole pendulum mass is then needed according to marine site mean wave energy Size determine.

This elongated pendulum mass, is fixed in carrier pipe with its waist, than the cloth symmetrical above and below of embodiment 6 during installation Put simply too much, efficiency is also lifted, so the pendulum mass of embodiment 6 can also be designed to an elongated entirety, with waist It is fixed on carrier.

Embodiment 9：

In embodiment 8, the two sections of pendulum mass, close to being arranged symmetrically, are so advantageous to device relative to carrier Steadily, and more wave impulse forces can be received, but due to the kinetic energy of wave be the increase with the depth of water and rapid decrease, institute It is actually seldom with the wave energy that the lower end of pendulum mass receives, so this pendulum mass structure still has the possibility of optimization.

Fig. 9 a are referred to, pendulum mass lower semisection is optimized for one big tripe shape by us, is closely connected with carrier, so, pendulum The form of body is just more succinct.The fixed form of device can be fixed by the way of embodiment 8, but what is used here is then into For the attached of blower foundation post, 15 be blower fan post in figure, and carrier 4 is fixed on blower fan post 15 by strut 25, and such case is fitted Conjunction is combined with large-scale deep-sea wind power plant, and they share mechanics rock-steady structure and transmission system, improves the stability and economy of electric power Benefit.Figure apoplexy column 15 is that carrier 4 provides anchor point, and carrier 4 then turns into the tie-beam of more blower fan posts, their mutually auxiliary phases Into.

Further, Fig. 9 b are referred to, the structure of pendulum mass 1 is further simplified in figure, reduces the quantity of lacing wire 23, is formed A kind of typical " three-stage ", whole pendulum mass are turned forward about 30 °~40 °, and hypomere is closely connected with the lower surface of carrier 4, in Duan Ze is fixed on the side of carrier 4, forms fulcrum, and epimere then configures the yaw 9 of a cattle horn shape, the arm of force is formed, if each Section is 2 meters long, then less than normal than existing large-scale pendulum device always with 8 meters, and 4 sections are made so can also suitably lengthen, this and sea Domain condition is relevant.The fixed form of carrier 4 can be foregoing several ways, but give a kind of new paragon here, 26 in figure For lifting column, upper end is fixed on the bottom (during making can global formation) of carrier 4, while seabed spud pile 12 is designed to by we Cylindrical cavity is left in taper type, centre, and the lower end of lifting column 26 is then inserted in the hole of frustum, such whole device can with Tide fluctuating, and carrier and can is firmly pind down, and can not rock translation.

Its 3 dimensional drawing refers to Fig. 9 c, it is seen that in this form pendulum mass profile and spread pattern all with the duck that nods (Wave Duck) device is similar, so the benefit so designed is self-evident, it becomes and pressure flexible membrane-based device one Sample is simple, but there is the absorption efficiency of the duck that nods (Wave Duck) equally.And the duck that nods (Wave Duck) device although have it is very high Absorptivity, but it is needed around very thick central axis, this adds increased friction and wear, and its internal hydraulic pressure conversion Mechanism is also extremely complex, so overall practicality is not strong.And the pendulum mass of the present invention does not both have without pivoting, inside yet Complicated hydraulic conversion mechanism, it is simply gently waved with its soft body around carrier pipe, just medium can be pressed into high pressure Pipeline；Simultaneously because it can absorb ripples static pressure potential energy, so its efficiency also will be lifted accordingly；There is no noise, without profit It is sliding, it is also much friendly to environment；Pendulum mass is flexible deformable, and viability is also much better than.So the present invention no matter from absorption efficiency, turn All it is impayable for changing each side such as efficiency, the easy degree of device, the friendliness of environment and survival ability.

Embodiment 10

Embodiment 9 and 8 is that carrier 4 is fixed on pile, and certain such a form can also be fixed on bank, for example use Bank base outrigger fixes carrier.Even it may be also secured on hull, and ship when needed sinks to device in seawater, so that it may It to absorb wave energy, can be not only used for generating electricity, fresh water processed can also be used for after supercharging, suitable for the ship stopped for a long time in off-lying sea and extra large work Facility.

So further, the present embodiment will attempt device to be fixed on seabed, the water plant one grown just as seabed Sample, such form can be what kind ofFigure 10 a are referred to, its internal principle and structure are substantially the same manner as Example 1, The difference is that carrier (pipeline) 4 is directly fixed on sea bed by the present embodiment, while in order that being formed when pendulum mass is swung most has The volume compression of effect, we additionally set strut 25 and support 29, pendulum mass waist are supported in, when pendulum mass is swung, with consolidating for waist Fixed end is that fulcrum waves bending, forms volume compression；Figure medium-height trestle 29 is connected with pendulum mass waist, and support is withstood in the upper end of strut 25 29, lower end is then fixed on sea bed, while yaw is designed to as curved a hand goes to hold in both hands wave, be advantageous to receive wave and Ripple is made in reduction backward.In view of the continuous change of tidal level, yaw should be designed to longer, accomplish not exclusively to flood during tidal height position as far as possible Not yet, damp low level does not reveal entirely.Certainly, device can also be made to be completely disposed under sea according to actual conditions.

This to be fixed in the arrangement in seabed, device is not just nearly free from machinery with tide fluctuation, this sampling device Noise, capacity of anti-storm is also most strong, and also highest, structural cost also relatively save efficiency, are a kind of highly desirable designs, be adapted to offshore compared with Near region.A pendulum mass has only been drawn in figure, actually should be many pendulum mass arrays on carrier, slightly leave spacing i.e. Can, while can be arranged in parallel two to five row's carriers according to the difference of marine site wave energy density, material is thus formed a seabed clump Woods and the new ecosystem, new home is provided for water plant and fish.

For the ease of civilian boat trip, the easily segmentation of carrier 4 is staggeredly arranged, and is one section appropriate with 300~500 meters.

Certainly, this arrangement form also is adapted for the pendulum mass of other forms, such as the pendulum mass of cylinder, refers to figure 10b, it is basically identical with Figure 10 a principles, the difference is that pendulum mass has been contoured to as a bottle, and yaw is then as a bottle Lid.It can be seen that the form of pendulum mass can be with varied, support 29 can also be made to be enclosed around pendulum mass one, and two struts open one again Point, it is possible to receive from wave from all directions, such case is adapted to away from continent and the shallower marine site of landform.

Embodiment 11：

In embodiment above, fluid media (medium) is extruded pendulum mass, is made a circle in elongated pipeline and promotes the hydraulic turbine to do It is back to again in pendulum mass after work(, and in fact, the medium in pendulum mass can not also circulate, only rely on the mechanical periodicity of internal pressure And liquid metal magnetohydrodynamic flowing is pushed directly on to generate electricity.

Refer to Figure 11 a, 11b, be two kinds to promote liquid metal magnetohydrodynamic the design drawing that generates electricity, in Figure 11 a, pendulum mass 1 is a kind of flexible cavity structure, is made up of flexible stretch-proof material, and lower end is fixed on the side of carrier 4, in it full of water or Air or the mixing of the two；One end of the soft capsule 28 of dumbbell shaped is placed in pendulum mass, and one end is placed in (this in the high pressure chest in carrier 4 In with pressure piping 5 replace high pressure chest), the soft capsule 28 of dumbbell shaped is built with the liquid-metal MHD for accounting for its half volume Body；Filled with gases at high pressure in high pressure chest, its pressure is equal to a quarter of maximum pressure caused by pendulum mass energy to half, its Effect is to provide elastic-restoring force；And permanent magnet 27 and two plate electrode (not shown)s then surround on four sides, be arranged symmetrically in it is mute " handle " place of the soft capsule of bell-shaped, form power channel.

So, attacked when wave, pendulum mass 1 just waves bending by fulcrum of fixing end, and then its interior pressure rise, promotes position The liquid metal magnetohydrodynamic in the soft capsule 28 of dumbbell shaped in the inner flows to one end of pressure piping 5 outside pendulum mass；After crest, pendulum Internal pressure disappears, and then the gas in pressure piping 5 just oppresses the metal magnetic current in the soft capsule 28 of the dumbbell shaped of position in the inner Direction of flow pendulum mass one end, while the volume of pendulum mass is recovered original full state.

As pendulum mass constantly waves, liquid metal magnetohydrodynamic constantly moves reciprocatingly at the soft capsule both ends of dumbbell shaped, in permanent magnetism So as to produce electric energy in two plate electrodes in the presence of body 27, then it is pooled to control centre's rectifying and pressure-regulating output stable power.

Reciprocal in view of magnetic fluid flowing, it is small when big during its speed, and the gas in high pressure chest compressed when Time also has portion of energy and is converted into heat and loses, so its efficiency will not be very high, is only suitable for small work(in this form The small-scale situation of rate, so we are also equipped with net cage for this equipment in figure, it can be exclusively used in as the small rule such as net cage or buoy Mould facility power, the rack and automation equipment of net cage are then fixed on carrier 4, share mechanics rock-steady structure and mooring system, To improve its comprehensive benefit.

Further, it is contemplated that its medium is without circulation, then actually carrier 4 is exactly the component that can cancel.It please join See Figure 11 b, we eliminate carrier 4, and high pressure chest is used as by the use of the inner chamber of yaw 9；Devise a kind of lambdoid support simultaneously Structure, it is fixed on seabed, naturally it is also possible to be fixed on other platforms.Wherein 25 be strut, and 29 be support, the slant setting of pendulum mass 1, Bottom is fixed on strut 25, and waist is fixed on support 29；And one end of the soft capsule 28 of dumbbell shaped is placed in pendulum mass, one end is then put In in yaw 9, gases at high pressure are full of in yaw 9, play elastic-restoring force.Its process of doing work is identical with Figure 11 a, different It is that such case make use of the space in yaw to play optimization structure as high pressure chest, reduce the effect of cost.Such case Compare and be adapted to be arranged on ship, be fixed on using strut 25 on hull, specifically then may be designed to lift, here not State more.

So this " institutional framework " has or not other except the fluid media (medium) used in above example

Because pendulum mass waves, extruding can be produced, so naturally, we are contemplated that piezoelectric principle, utilizes pendulum The extruding of piezoelectric element generates electricity in body to body.Refer to Fig. 2 a, the body wall of pendulum mass is interlayer in figure, and we can be by piezoelectricity Element is arranged between the interlayer space 10 of pendulum mass body wall, and air is then full of in the cavity of pendulum mass, plays elastic recovery.By Cancel in the cavity without medium, therefore in carrier and check valve can, pendulum mass is directly anchored on entity pedestal.

During work, pendulum mass waves bending by fulcrum of fixing end, and side is pressurized, and side tension, oppresses its internal piezoelectricity Element, voltage and electric current are then produced, these electric currents are collected regulation by us again, export into stable electric energy.In such cases, Pendulum mass can be designed to it is more elongated, in order to which pendulum mass waves bending, to body wall produce pressure.

So far, what 12 kinds of embodiments of the above be apparent from reflects design and the technical characterstic of the present invention, that is, utilizes Non-stretchable flexible hollow pendulum mass waves bending by fulcrum of fixing end, volume compression is formed, so as to pendulum mass inside " institutional framework " produce and pressure and it done work, so as to absorb Wave energy.
