Technical field
Present invention relates in general to pumping equipment, and it is more specific but without limitation, relate to the buoyancy pump equipment in the buoyancy pump power system, described buoyancy pump power system utilizes the mobile volume of water that gas, liquid and its combination are moved to the second place from primary importance.
Background technique
There has been a lot of trials to utilize common so-called wave phenomenon and has been the available reliable energy observed Conversion of energy in the wave phenomenon.The wave phenomenon relates to the transmission of energy and passes the momentum of vibratory impulse of the various states of material, for example, is exactly to pass through vacuum under electromagnetic situation.In theory, medium itself can't move when energy is flowed through.The particle that forms medium just can move transmitting the translation of energy or angle (track) pattern to another from one.The wave for example wave on the sea has neither vertical non-again horizontal movement of particles.The motion of particle can relate to the component in compressional wave and the shear wave usually in the wave.Compressional wave is usually directed to particle moving forward and backward along the energy transfer direction.These waves are by all state transfer energy of material.Shear wave is usually directed to particle and the energy transfer direction is rectangular moves forward and backward.These waves only transmit energy by solid particle.In the track wave, particle can move along track.These waves can transmit energy along the surface of contact between two kinds of fluids (liquid or gas).
Occur in the component that wave on the sea for example is usually directed to compressional wave and shear wave, this is because the particle in the wave can move along circular track on the surface of contact of atmosphere and ocean.Wave has several features that are easy to discern usually.This feature comprises: crest is the peak of wave; Trough is the minimum point of wave; Highly, be perpendicular distance between crest and the trough; Wavelength is the horizontal equivalent between crest and the trough; Cycle is that a wavelength is through the out-of-date used time; Frequency is the number of time per unit through the wave of immovable point; And amplitude, amplitude is half of height distance and the energy that equals wave.
There has been the trial that much can trace back to last century to utilize and use the energy that produces by the wave phenomenon, for example in the disclosed system in 597,833 the U. S. Patent that is numbered of issue on January 25th, 1898.These effort comprise that erectting sea wall obtains the energy that obtains from the wave phenomenon; Track and guide track system that utilization relates to complicated arrangement to obtain energy from the wave phenomenon; Development only is suitable for the pumping system of shallow water wave system; Take place therein to construct tower etc. near the mobile seashore of ebb tide and morning and evening tides.Be not described in detail other trial of having made at this.

Traditional energy for example the consumption of oil need replace energy source efficiently.Greenhouse effect are considered to cause the reason of this phenomenons such as global warming, and it has also established the needs of the equipment that generates for eco-friendly energy.The decline in the traditional fuel source that is easy to use causes the increase of the cost of energy that can feel in the whole world.This just added eco-friendly for forming, efficiently, another demand of energy device cheaply.
Can feel observantly for needs that be easy to obtain, more cheap energy source in the whole world.On for example China and other places, on the river, build the dam and think that rapid and ever-increasing population generates a large amount of energy.These planning may spend 20 or finish more for many years.Build the usability of the energy that dam planning generates even when planning is finished, also can not begin by this.Therefore, also in a single day building the energy device existence needs that just can provide energy immediately and have short construction period.

In order to address the above problem, provide the potential energy that exists in the proper motion of buoyancy pump equipment with the unusual water of large volume to be converted to mechanical energy with high relatively efficient, wherein can be in ocean, lake and river the discovery form be to surge and the water of wave large volume.Buoyancy pump equipment is suitable for pump gas and liquid or both combinations.Same and when this pointed out, gas was defined as fluid or gas, therefore comprise the sky G﹠W.Just can utilize as the pump gas of mechanical power sources then or liquid comes turbo machine, pneumatic tool, ventilation plant or use any other machinery of this power that power is provided.Mechanical power sources also can be used to utilize similar mechanical translation device to generate electric energy.
In conjunction with referring to Fig. 1 to Fig. 2 C, in each view, shown buoyancy pump equipment 100 now according to the first embodiment of the present invention.Buoyancy pump equipment 100 comprises base 102, be connected to an end base 102 and the other end be connected to by the buoyancy cylinder 104 of buoyancy cylinder cap 106 closures with an end buoyancy cylinder cap 106 and generally with buoyancy cylinder 104 coaxillay aligned piston cylinders 108.Another end of piston cylinder 108 is by piston cylinder cover 110 closures.Buoyancy cylinder 104 an end by the upper surface of base 102 closed and in another end by buoyancy cylinder cap 106 closures to define buoyancy chamber 112 therein.
Being as general as columniform buoyancy block 114 places buoyancy chamber 112 to move axially therein slidably.The opening 118 that the piston shaft 116 that is connected to the upper end of buoyancy block 114 passes in the buoyancy cylinder cap 106 axially extends thus generally.Another end that columniform generally piston 120 places piston cylinder 108 slidably and is connected to piston shaft 116 in the lower end is to move axially generally with it.Piston cylinder 108 an end by the upper surface of piston 120 closed and in another end by piston cylinder cover 110 closures to define piston chamber 122 therein.
The buoyancy cylinder 104 that also can be the buoyancy block shell can be connected on the upper surface of base 102 via chain 134, and chain 134 is connected on the buoyancy cylinder 104.In this way, chain 134 just makes buoyancy cylinder 104 stable on base 102.Be appreciated that backguy or other connection set can be used for buoyancy cylinder 104 is connected to base 102, and the present invention is not limited to use chain 134 as connection set.
In another example, in the water body with 10 feet water depths, buoyancy cylinder must be at least 10 feet, and makes 7 feet additional operation highly add 10 feet to upward to allow the motion of buoyancy block in inside, buoyancy chamber.Therefore, buoyancy cylinder will and have 7 feet available travel for 17 feet high.If change but water body has morning and evening tides, this example also can slight modification.
In the example that changes, 10 feet marine and have a loss that buoyancy pump equipment that 2 feet morning and evening tides change can cause 2 feet available travel.Consider this change, the annual low tide and the missionary society of climax are increased on the length of the buoyancy cylinder that will dispose.That is, the highest wave height is that 7 feet, low tide are that 10 feet and climax are that the difference of low tide and climax is 4 feet in 14 feet the environment therein.This can add+10 feet (operating to allow buoyancy pump equipment)+4 feet (low tide and climax poor) to buoyancy cylinder length (7 feet) (being used for the highest wave height) under the low tide situation, so total buoyancy cylinder length is 21 feet.The wave that this allows in the sky of climax 7 feet stroke and uses process fully.
The buoyancy block 114 that is arranged in 112 inside, buoyancy chamber is as general as columniform and has cone-shaped upper surface.Buoyancy block 114 has predetermined buoyancy, like this buoyancy block 114 will with cycle that the hydraulic pressure or the pressure system characteristic of the hydrokinetics of the water of wherein having placed buoyancy pump equipment 100 and buoyancy pump equipment 100 itself conform in move.The buoyancy of buoyancy block 114 can be regulated according to the characteristic and the hydrokinetics of water and system equally.This adjusting can realize by following manner: (1) manually or remotely regulates buoyancy block 114 vertically or radially or along both direction with respect to buoyancy chamber 112; (2) regulate other characteristic that influences the characteristic of buoyancy block 114 in water.Below with more detailed description exemplary adjustments device.
For packed-piston chamber 122, the piston 120 that is arranged in piston cylinder 108 inside slidably can comprise the sealing of extending around the periphery of piston 120 therein.Sealing is suitable for preventing that gas or liquid from leaking in the piston chamber 122 or from piston chamber 122 leaks into the environment from environment, and piston 120 remains on piston chamber's 122 slides within.
Because the athletic meeting of buoyancy block 114 in buoyancy cylinder 104 is by other element obstruction that rubs or enter buoyancy cylinder 104, so a plurality of pad 140 can be connected on the internal surface of buoyancy cylinder 104.Pad 140 extends axially along the periphery of buoyancy cylinder 104, and be used for stablizing buoyancy block 114 buoyancy cylinder inside towards.Pad 140 can be made of suitable material, and the friction factor between pad 140 and the buoyancy block 114 is just near zero like this.
In order to limit the axial motion of buoyancy block 114 buoyancy cylinders 104 inside, a plurality of stoppers 142 can be arranged on the internal surface of buoyancy cylinder 104 and be arranged on its underpart.The position of stopper 142 can be regulated with the expectation running length of coupling piston 120 in piston cylinder 108 inside.
Should be appreciated that the axial motion meeting of buoyancy block 114 in buoyancy cylinder 104 is converted to the axial motion of piston 120 in piston cylinder 108 inside via piston shaft 116.Piston shaft 116 and jointing 136 are also with respect to the position of buoyancy block 114 fixed pistons 120.
Referring now to Fig. 3 A-3C,, wherein shown exemplary buoyancy block 300 with item facial planes, side and isometric view respectively.Buoyancy block 300 has the axially open 302 that is suitable for receiving connecting joint 136 (Fig. 2 B) and therefore is connected to (Fig. 1) on the piston shaft 116.Top 304 is from the inwardly taper gradually of peripheral radial of buoyancy block 300, and ends at axially open 302 places.The axial motion of the taper buoyancy aid piece 300 on the top 304 especially is immersed in the water and during towards water surperficial mobile in buoyancy block 300.Separate though top 304 is shown as with buoyancy block 300 bottoms 306, should be appreciated that taper can be suitable for the arbitrary portion of buoyancy block 300 and end at axially open 302 sentencing and being convenient to the axial motion of buoyancy block 300 in water.
Referring now to Fig. 3 D,, wherein shown the partial sectional view of optional exemplary buoyancy block 350.Buoyancy block 350 has top 352 and bottom 354.Top 352 has radial taper part 356 so that the axial motion of buoyancy block 350 in water also has the non-tapering part 358 that is connected on the tapering part 356.Screw thread 360 is formed on the inner periphery on top 352 of buoyancy block 350.
The bottom 354 of buoyancy block is as general as cylindrical, and has the screw thread 362 on a plurality of outer peripherys that are formed at bottom 354.The screw thread 362 of bottom 354 is suitable for screw thread 360 coupling on top 352 and allows the axial motion of bottom 354 with respect to top 352.
In conjunction with referring to Fig. 3 E and 3F, wherein shown the item view of example tunable joint buoyancy block base 370 now.Can regulate buoyancy block base 370 comprises outside plate 372, be connected to inner panel 374 on the outside plate 372, be connected to axial arranged motor 376 and a plurality of Expansion bar 380 that is connected on gear 378 and the outside plate 372 on the gear 378.The circumference of buoyancy block base 370 is by plasticity, thermoplasticity or for example rubber seal of other sealing material 382.Therefore sealing material 382 can prevent that environmentally conscious materials from entering in the buoyancy block base 370.
Outside plate 372 is connected on the inner panel 374 via roller 384.Roller 384 allows the motion of outside plate 372 with respect to inner panel 374.The guiding device that is used for roller 384 can place outside plate 372 and inner panel 374 surface separately.
For example, Fig. 3 E has shown that buoyancy block base 370 is in the retracted position, has the diameter by the D1 indication.When motor 376 was actuated to be rotated in a clockwise direction gear 378, Expansion bar 380 correspondingly rotated, and the diameter of the buoyancy block base 380 that therefore expands is indicated shown in Fig. 3 F and by D2.Thermoplastic material 382 can expand with respect to the expansion of buoyancy block diameter equally.Therefore, when being used for buoyancy pump equipment, buoyancy block base 370 can radial expansion or is shunk to increase or the diameter of the buoyancy block that reduces to be associated.Though be appreciated that to be shown as columniform generally configuration, buoyancy block base 370 can be according to buoyancy pump design of plant and requirement and is other configuration.
Referring now to Fig. 4 A, 4B and 4C,, buoyancy pump equipment 100 is shown as when wave (W) is flowed through buoyancy chamber 112 (Fig. 1) and is in each position.The wave (W) of buoyancy pump equipment 100 of flowing through has the geometric properties below comprising:
Wave height (W
H) be crest (C) or the trough (T) of peak and wave or the perpendicular distance between the low spot of wave;
Wavelength (W
L) be for example crest on the wave or the distance between the trough of equivalent point; And
Static water level (S
WL) be the surface of water when not having wave, be generally wave height (W
H) mid point.
In Fig. 4 A, buoyancy block 114 is shown as and is in its crest (C by wave (W) when fluid is exported by outlet valve 126
1) the highest vertical position supported.When moving through buoyancy chamber 112, wave (W) is approximately wavelength (W
L) half (1/2) apart from the time, as shown in Fig. 4 B, buoyancy block 114 can fall to minimum vertical position in its trough at wave (W) (T) during by inlet valve 124 suctions at fluid.In Fig. 4 C, wave (W) has moved whole wavelength (W
L), buoyancy block 114 just turns back to following crest (C like this
2) on the highest vertical position and fluid export once more by outlet valve 126.
Piston stroke (the P of buoyancy pump equipment 100
S) (not shown) is defined as at wave (W) and moves through 112 1 the wavelength (W in buoyancy chamber
L) time piston 120 distance that moves by buoyancy block 114.When wave (W) when moving through buoyancy chamber 112, the distance (B that buoyancy block 114 descends
D) equal from placing the crest (C of Fig. 4 A
1) to the wave height of the trough that places Fig. 4 B (T), raise then from the trough (T) that places Fig. 4 B to the crest (C that places Fig. 4 C
2) identical distance (B

Therefore, piston 120 has " half trip " of decline and " half trip " that rises, and they are known as " descending stroke " and " lift stroke " respectively.

PLimit.As shown in Fig. 4 A, when wave moves when striding across buoyancy pump equipment 100, buoyancy block can move with the wave direct correlation of process.
When buoyancy pump equipment 100 was in the zero pressure state, it was P that buoyancy block 114 can move the ultimate range that is generated by wave motion
Smax=2W
LThis can change piston 120 complete half trip in piston cylinder 108 into and moves, and this can force liquid to flow out from piston chamber by valve.
Return referring to Fig. 1 and in operation, buoyancy pump equipment 100 be arranged in initially in the water body that ocean for example, lake, river or other generate wave or the environment of surging after, the initial pressures in outlet line 130, outlet valve 126 and the piston chamber 122 will be from the zero pressure state.Wave with recognition performance can arrive buoyancy pump equipment 100.Water from wave can be filled buoyancy chamber 112 gradually.When water was filled buoyancy chamber 112, buoyancy block 114 beginnings raise along with the water that rises in the buoyancy chamber 112.
The buoyancy of buoyancy block 114 is designed to most buoyancy block 114 and can floats over outside (ride) water in buoyancy chamber 112 than the highland relatively, therefore allows the axial motion of buoyancy block 114 in buoyancy chamber 112.When wave left, buoyancy block 114 was along with the water of sedimentations in the buoyancy chamber 112 and reduce under the effect of gravity.Piston shaft 116 with the movement conversion of buoyancy block 114 to piston 120.
In another end of scope (spectrum), when buoyancy pump equipment 100 began with the pressure maximum in outlet line 130 and the outlet valve 130, in fact most buoyancy block 114 can be immersed in the water of wherein having placed buoyancy pump equipment 100.This can cause piston 120 to pass the running length that reduces of piston chamber 122.
At given wave or surge through out-of-date, what gravity can be to buoyancy block 114 and piston 120 provides power to down stroke.Along with the given wave or the rising of surging, the buoyancy of buoyancy block 114 can provide lifting force/power to piston 120 via piston shaft 116.When from the pressure of the piston 120 of outlet valve 126 when low, buoyancy block 114 floats over outside the water in the buoyancy chamber, because required uplift is only with respect to the back pressure that is sent to via outlet valve 126 in the piston chamber 122 than the highland relatively.
When piston pressure was very high, the axial motion of buoyancy block 114 in the buoyancy chamber will be restricted, and this causes buoyancy block 114 to float over bottom in the water.Under the certain high pressure state in piston chamber 122, almost entirely submergence and still in the buoyancy chamber, move axially liquid or gas of buoyancy block 114 with 122 inside, pumping piston chamber.Buoyancy block 114 its buoyancy when submergence fully at last, can become very big, even can not provide enough lifting forces to come mobile piston 120 yet like this from the pressure of outlet valve 126.At this moment, buoyancy block 114 and piston 120 can stop motion, even rise with respect to buoyancy pump equipment 100 at the wave or the continuation of surging.
For example, in the buoyancy pump equipment with the buoyancy block of disposing one foot height in the pressure maximum state, buoyancy pump equipment will lose about one foot pumping stroke at piston cylinder.Iff the wave that occurs a foot, buoyancy pump equipment will can not inhaled by pump.
If do not reach this point, buoyancy block 114 and piston 120 will continue to move axially until wave or surge along with given wave or the rising of surging to reach its maximum height separately, allow piston 120 in piston chamber 122 by outlet valve 126 moving liquids or gas.But this process can keep the maximum compression point in reaching piston chamber 122 still allow outside flowing.
When almost submergence or submergence but still when moving axially of buoyancy block 114, this is called as the high waterline of buoyancy pump equipment 100.When wave or surge through out-of-date, the minimum point of the decline of buoyancy block 114 is called as the low waterline of buoyancy pump equipment 100.Distance between high waterline and the low waterline has been determined the power stroke of piston 120.
For example, when gas is during with the medium that is pumped, can be conditioned to be connected to suction line 128 on the gas source and can puts into wherein that for example ambient air is communicated with and the position of receiver gases therefrom with gaseous environment.Outlet line 130 can be connected to base 102 and be used for store compressed gas.Be appreciated that outlet line 130 can be connected to another position and be used to store gas, for example be connected on the fixing holding vessel that is positioned at buoyancy pump equipment 100 outsides.
In examples of gases, when piston 120 descended along with the wave of sedimentation, its can generate vacuum in piston chamber 122, and by suction line 128 and inlet valve 124 with in the air suction piston chamber 122.In the trough of wave and after water emptying buoyancy chamber 112, perhaps when buoyancy block 114 contacted with the stopper that further moves downward 142 that suppresses buoyancy block 114 and piston 120, the gas of maximum flow was filled piston chamber 122.
When wave begins to go up and water when filling buoyancy chamber 112 gradually, buoyancy block 114 will be exposed in the water and contact with it.The buoyancy of buoyancy block 114 causes the lifting naturally of the water of rise in the buoyancy block 114 response buoyancy chambers 112.The fixed position with respect to piston 120 of adopting for ease of piston shaft 116 owing to buoyancy block 114 is so piston 120 can be directly raise with respect to the lifting of buoyancy block 114.
The gas that has imported in the piston chamber 122 can compress piston chamber 122 in when buoyancy block 114 raises, and has overcome line pressure in the outlet line 130 until the pressure of pressurized gas.At this moment, gas flow is by outlet valve 126 and outlet line 130 and be transported to desired locations for using or storage.For example, can use aforesaid exemplary base 102 or other memory location to come store compressed gas.Can also imagine that if situation needs, gas can disperse in the atmosphere.
In case wave reaches its maximum height when it flows through buoyancy pump equipment 100, water just begins to leave buoyancy chamber 112.It is downward with wave that gravity can promote buoyancy block 114, causes moving downward of piston 120, and this can generate vacuum in piston chamber 122.Vacuum arrives piston chamber 122 with gas pumping once more, as indicated above, therefore along with each wave in succession repeats this process, therefore drive buoyancy pump equipment 100 with continuously and circularly with gas pumping in piston chamber 122, pressurized gas in piston chamber 122, and force gas to enter base 102 from piston chamber 122.Piston 120 gas that also compression is stored in the base 102 in each cycle no longer overcomes the gas of storage and the pressure in the outlet line 130 until buoyancy block 114.During this time, buoyancy block 114 no longer rises with respect to wave.
In another example, when liquid for the medium that is pumped the time, it is for example waterborne that suction line 128 is connected to liquid environment.Outlet line 130 can be connected to the storage reservoir, and the storage reservoir includes, but are not limited to lakebed, water tower or other water system.When incompressible liquid when for example water is pumped, piston shaft 116 may not need to regulate, in case the incompressible liquid of piston chamber's 122 complete filling, buoyancy pump equipment 100 will pumping.
In examples of liquids, the decline meeting of piston 120 correspondingly generates vacuum in piston chamber 122, and this can be by suction line 128 and inlet valve 124 with in the water suction piston chamber 122.In the trough of wave and after water emptying buoyancy chamber 112, perhaps when buoyancy block 114 contacted with the stopper that further moves downward 142 that stops buoyancy block 114, the liquid of maximum flow can be filled piston chamber 122.
When wave begins to go up and water when filling buoyancy chamber 112 gradually, buoyancy block 114 will be exposed in the water and contact with it.The buoyancy of buoyancy block 114 causes promoting gradually naturally of the water that goes up gradually in the buoyancy block 114 response buoyancy chambers 112.The fixedly character with respect to piston 120 that adopts for ease of piston shaft 116 owing to buoyancy block 114 is so piston 120 can be directly raise gradually with respect to the lifting of buoyancy block 114.Under the situation of water as medium, the incompressible water that goes up in the piston chamber 122 can overcome the line pressure in the outlet line 130.At this moment, water flows by outlet valve 126 and outlet line 130 and is transported to desired locations for using or storage.Can think about it that if situation needs, liquid and/or gas can disperse in the atmosphere.
In case wave is at its flow through buoyancy pump equipment 100 and reach its maximum height when leaving, water just begins to leave gradually buoyancy chamber 112.Gravity can promote buoyancy block 114 downwards, causes moving downward of piston 120, and can generate vacuum in piston chamber 122.Vacuum is used for liquid and/or gas pumping in piston chamber 122.This process can repeat along with each wave in succession, therefore drives buoyancy pump equipment 100 with continuously and circularly liquid and/or water are drawn in the piston chamber 122, and from 122 li pumping liquids of piston chamber and/or water.
Be appreciated that in examples of liquids,, the loss of uplift must be multiply by a coefficient owing to there is weight in the piston chamber 122 from water/liquid.Yet in examples of gases, because gas is compared lighter performance relatively with liquid, in fact this loss does not exist.Loss in the examples of liquids can overcome by the adjusting function of buoyancy block 114.
The environment of using it is depended in the operation of buoyancy pump equipment 100.For example, when buoyancy pump equipment 100 is positioned at when having predetermined annualized wave mean value, buoyancy pump equipment 100 must be connected on the structure with respect to wave, perhaps places ballast, and buoyancy pump equipment will keep its relative position with respect to wave like this.This structure can be that fix or fixing basically, can comprise that perhaps seaworthiness container, flatbed dispose or buoyancy pump equipment 100 is directly connected on the seabed.This connection is common, especially in oil and natural gas industry, and expection will with buoyancy pump equipment 100 collaborative uses the according to the novelty of principle of the present invention.
Be used for via the uplift of piston shaft driven plunger in piston cylinder directly related with the lifting capacity of buoyancy block.In theory, for example, in the total displacement of 100 pounds of (lbs) given buoyancy block, from total displacement (100lbs pound), deduct the lifting capacity that buoyancy block weight (10 pounds), piston shaft, other various parts of connector (5 pounds) and piston weight (2.5 pounds) can remain 82.5 pounds.The empirical test of buoyancy pump equipment 100 can be with about 96% efficient operation for this formula.
Can expect that buoyancy pump equipment 100 can be used for white calibration, and it keeps normally stable position with respect to the position in seabed and the wave environment therefore arranged with respect to it.For example, ballast box can be connected on the buoyancy pump equipment 100 and fill suitable ballast.Therefore buoyancy pump equipment 100 can also regulate the position of buoyancy pump equipment 100 with respect to wave environment with gas or liquid pumping in ballast box.This configuration can realize by being connected to buoyancy pump equipment 100 outlet lines 130 on the ballast box and providing control system to regulate under the predetermined situations to flow into and flow out ballast box.Can regulate and using gases and liquid according to the desired locations of buoyancy pump equipment 100.
Can also estimate that the length of piston 120 and width (diameter) can be regulated in response to the performance of pumped medium or piston 120, buoyancy chamber 112 and buoyancy block 114.Equally, piston 120 can have scalable adjusting etc. thereon to be similar to the height or the width of buoyancy block 300 (seeing Fig. 3 A-3C) regulating piston 120.
For example, the flow velocity of in buoyancy pump equipment 100, setting and the internal diameter and the height correlation of pressure and piston cylinder 108.Piston cylinder 108 is big more and the stroke of piston in piston cylinder 108 is long more, will realize more substantial liquid or air-flow with the pressure minimum that occurs.Piston cylinder 108 is more little and the stroke of piston in piston cylinder 108 is short more, maximum pressure will occur and can realize the liquid or the air-flow of minimum flow liquid or air-flow.
Can notify the generation frictional loss, although this loss is moderate, this is relevant with the length and the size of other material that comprises inlet valve 124 and outlet valve 126 with suction line 128 and outlet line 130.
The size of buoyancy chamber 112 and buoyancy block 114 also can be regulated so that maximum buoyancy pump device efficiency to be provided.This adjusting can for example manually be finished by change parts, or by comprising that on each parts telescopic section automatically finishes, or regulates the performance of expectation parts and remotely realize by the design control system.In this way, buoyancy pump equipment 100 can be calibrated to act on the wave of the performance with change, and buoyancy pump equipment 100 just can utilize big wave, rips and have the wave that more relaxes performance like this.
In order to utilize this wave, buoyancy pump equipment 100 is not fixed on the base 102 inevitably.Buoyancy pump equipment can for example be installed at the end of water body, is fixed on the structure at the end that is installed in water body, is fixed on the hard floating platform, is fixed on the sea wall, or is fixed on other mounting point that stabilized platform or its equivalent are provided.
The function that the size of buoyancy pump equipment 100 is relevant with the wave or the middle amount of energy of surging with buoyancy pump equipment 100 can be determined by Several Factors.For example, these factors comprise: annual high and low and average wave size; Annual high and low and average tide mark; Wave or the average period of surging; Liquid is in the wave or the locational degree of depth of surging; From the beach to the wave or the distance of surging; Near the wave or the position of surging landform; Structure with buoyancy pump equipment 100.Can expect that buoyancy pump equipment 100 can be used in combination to come the gas or the liquid of pumping large volume by pump with grid mode and other buoyancy pump equipment.
For the horsepower of determining to generate, can calculate wave horsepower (potential energy) and buoyancy block horsepower in decline and lifting configuration by given wave height and speed.By these data, can calculate the reciprocating pump horsepower of water and air pumping configuration.To this calculating be described according to exemplary test configurations below.

As wave (W) (Fig. 4 B and 4C) when the lift stroke relaying continues into by buoyancy chamber 104, buoyancy block 104 can raise until it at crest (C with wave

3. piston pumping merit (CFM/PSI)
When the buoyancy pump equipment disposition became according to following formula pumps water, piston can come pumps water with the given speed of cubic foot per minute (CFM) and the setting pressure of pound/square inch (PSI) for each half (1/2) stroke:
PF=piston water flow=(S

Like this
PF=(1.74 ft

＝10.88?CFM＝0.181?CFS。
Determine piston hydraulic pressure (PSI) in each half (1/2) stroke in the buoyancy pump equipment (PP) by following equation:
PP＝{UW

Therefore, for top exemplary value, the PSI/ stroke that is used for exemplary buoyancy pump equipment is calculated as follows:
PP＝[31,386?lbs-(1.74?ft
3)(8.33?lbs/gal)(7.48?gal/ft
3)]/250in
2＝(31,386?lbs-108?1bs)/250?in

=125 PSI/ strokes.
When buoyancy pump was configured to pumped air, the surface area of piston can increase compressibility with make-up air to realize similar result.If the radius of piston increases to 12.6 inches, the surface area (SA of piston
P) just increase to 498.76 square inches.And, the impost [(S of the water above piston
V) (D) (7.48 gal/ft

PF
a＝21.7?CFM
PP
a=51.8 PSI/ strokes.
Because those of ordinary skill in the art is readily appreciated that the difference of using piston to come pumps water or air, so remaining example will be told about pumps water emphatically.
4. the HP that the generator that can use generates
Be connected to and be used for when the exemplary water turbine provides on the exemplary water storage box of power, the empirical correlation below using being measured the power that is generated by buoyancy pump equipment when being in water pump the exemplary buoyancy pump equipment in putting of providing and delivering:

Eff=based on turbine efficiency=90% that has water turbine now
KW=ft/sec is with respect to conversion factor=11.8 of KW
HP=KW is with respect to conversion factor=.746 of HP
Therefore, use top exemplary value and, utilize the output BP of the exemplary power system of buoyancy pump equipment to be calculated as follows in conjunction with existing calculating:
BP＝{[(125)(.88)(2.310)-[(0.068)(2.310)(10)(5.280)]}[(0.181)(0.9/11.8)/.746]
=.4558 (available total output HP).
When buoyancy pump is configured to pumped air, the output power (BP of the example system of numerical value above using
a) be approximately 2.72 HP.Use is for example comprised in the U.S. Patent No. 5,555,728 disclosed a kind of air turbine rather than uses water turbine to generate output power wherein this patent is hereby incorporated by.
5. the comparison of input HP and output HP efficient
Therefore, input HP can followingly determine with respect to the conversion efficiency of output HP:
Conversion efficiency=BP/BB
T=4.558/7.92=57%.
Therefore, use experience and gross data are appreciated that according to the exemplary buoyancy pump equipment of principle of the present invention when using with the exemplary water turbine is collaborative, from the wave (BB of process
T) horsepower that obtains is approximately 57% with the conversion efficiency of the BP that exports, this just can be used as power source.
Example B: average wave size
Top example calculation is to use exemplary buoyancy block 114 ' to make, and this exemplary buoyancy block 114 ' has geometrical shape and the height (h that depends on buoyancy block 114 '
1+ h
2) fixed diameter (d
1).Be appreciated that wave height (W
H) can change at different positions or for each position different time in 1 year.Therefore, reconfigure or regulate this buoyancy block with regard to hope based on the wave characteristics that changes as mentioned above.In order to guarantee high efficiency, can regulate the height and/or the diameter of buoyancy block 114 '.For example, buoyancy block 114 ' can design or regulate to increase the height (h of its base 104 ' a
1) and associated diameters to adapt to the bigger wave height (W that has as described below
H) wave.
If wave height (W
H) increase to 9.016 feet (waves of average-size), the height (h of buoyancy block base from 5.0 feet
1) will increase by 1.5 feet (referring to Fig. 4 D), that is, " warpage " of buoyancy block, thus the overall performance of buoyancy pump equipment in having average 9 feet bigger water body of surging strengthened.Correspondingly, the running length of piston can increase and the stroke number can reduce, and is as described below:
Stroke=5.52
Length of piston travel=42.2 in
Like this
S
V(volume/stroke)=12.8 ft
3
If all other factors keep identical and use above-mentioned formula, just can make up following table,
Table 1:
Table 1
| Value | 5 feet wave | 9.016 the wave of |
|
| 1 | |
382 horsepowers | 2952 |
| 2 | Buoyancy block power BB DBB TBB T | 0.79 7.13 horsepowers 7.92 horsepowers of horsepower | 2.05 31.67 horsepowers 33.72 horsepowers of horsepower |

| 4 | Generator power (BP) | .4558 horsepower | 20.32 horsepower |
| 5 | Pump efficiency | 57％ | 60％ |
Therefore, as can be seen, the buoyancy pump height increased that 1.5 feet meetings cause promoting and bigger horsepower and have bigger shaft horsepower in the example system of improved overall efficiency when reducing buoyancy block.Basically, the usability of bigger wave somewhere is for (for example having the bigger flow velocity of generation, PF=27.98CFM) the bigger buoyancy block and the buoyancy pump of piston provide the wave power source, and therefore provide more horsepower output (for example, BP=20.32 HP) at given location.
As indicated above, the diameter (d of buoyancy block 114 '
1) (referring to Fig. 4 D) also can regulate to adapt to the bigger wave in somewhere.Following table one table 2 has shown at velocity of wave translation (W

The data of table 2 are based on wave height with indication and move with 3 miles speed per hour and generate with the wave that 8 miles speed per hour moves for the high speed wave for the low speed wave.Equation mentioned above is used to calculate the low and high wave horsepower under being provided with.The diameter of buoyancy block or width be conditioned with shown in and carry out the maximizing efficiency that makes buoyancy pump with respect to the wave height that changes and velocity of wave translation in the aforesaid bigger wave environment.
Wave, surge or current big more and fast more, can be just big more by the potential energy that buoyancy pump equipment extracts.Equally, buoyancy block is big more, no matter is height or diameter, just can extract bigger potential energy from water.Wave, surge or current are more little and slow more, can be just more little by the potential energy that buoyancy pump equipment extracts from water.Similarly, buoyancy block is more little, and the potential energy that can extract from water will be more little.In order to optimize the potential energy that from buoyancy pump equipment 100, obtains, buoyancy block 114 submergence and should not surpass the width or the height of the wave or the arc of surging fully.
Above all examples wave of all supposing specific dimensions particular place can with and based on normal daily basis with the buoyancy pump equipment of efficient operation on.Fortunately, can obtain from several sources, comprising the website that is hereby incorporated by: http://www.ndbc.noaa.gov for the data of the wave height on the special position in every day in 1 year.Below table (table 3) shown January calendar year 2001 of obtaining and the wave data in February calendar year 2001 from the Gray Si port of the State of Washington.

Figure 17 A is the diagram in example pump zone 1700, and wherein pump zone 1700 comprises the wave 1706 that is designed to respond in the ocean 1708 and with the buoyancy pump equipment 1702 of fluid drives in the reservoir 1704.Pump zone 1700 is designed to the grid of buoyancy pump equipment 1702, comprises the row 1710 and the row 1712 in the location 1713 that is used for the buoyancy pump equipment 1702 that will be placed.Two buoyancy pump equipment 1702 are separated or separated to vacant lot section along row along every row.Similarly, along the vacant lot section of a row along two buoyancy pump equipment 1702 of every column split.By separating or separate buoyancy pump equipment 1702 as shown in the figure, will therefore allow the buoyancy pump equipment 1714c reception and first buoyancy pump equipment 1714a and the received substantially the same Wave energy of 1714b that is listed as among the c1 among the secondary series c2 at secondary series c2 and along vertically before the buoyancy pump equipment 1714c of the capable r13 of two buoyancy pump equipment 1714a and 1714b and the capable r14 between the r15, forming again through the first row c1 and at the wave between two buoyancy pump equipment 1714a and the 1714b.The separation of buoyancy pump equipment 1702 also helps to make the quantity of the energy that flows out from each wave to be reduced to minimum.Be reduced to minimumly by the quantity that makes the energy that flows out from wave, each the buoyancy pump equipment 1702 that is arranged in pump zone 1700 can equally provide power basically.Should be appreciated that can utilize to wave provides other configuration of the identical or similar minimum buoyancy pump equipment of changing 1702 to provide the highest wave energy to each pump.Configuration, seabeach 1714 and each the substantially the same wave of pump zone 1700 receptions that is not positioned at 1714 fronts, seabeach in the pump zone 1700 by using Figure 17.Therefore, pump zone 1700 is configured in that to generate in the power by wave be a kind of eco-friendly solution.
Figure 17 B is the enlarged view of configuration that comprises the buoyancy pump equipment 1702 of specific buoyancy pump equipment 1714a-1714c.The outlet line 1718a of buoyancy pump equipment 1714a and 1714b and 1718b are configured to respectively extend towards the capable r14 that comprises buoyancy pump equipment 1714c along the first row c1 from each buoyancy pump equipment 1714a and 1714b.Outlet line 1718a and 1718b are connected to and follow r14 on another outlet line 1718c of seabeach (1716) extension.Therefore, the outlet line (not shown) from buoyancy pump 1714c may be connected on the outlet line 1718c.In addition, can be connected to from the outlet line of other buoyancy pump 1702 that is arranged in capable r13-r15 and carry the flowing material (being liquid or gas) of discharging from buoyancy pump equipment 1702 on the outlet line 1718c to being arranged in land or other locational reservoir (not shown).Should be appreciated that other that can utilize outlet line disposes is transported to flowing material in the reservoir.Other configuration can structurally or be gone up different how much.For example, each outlet line 1718a and 1718b can keep separated from one another rather than outlet line 1718a and 1718b are connected on the single outlet line 1718c.
Continuation has wherein shown the exemplary configuration size that is used for the pump grid referring to Figure 17 B.Each buoyancy pump equipment 1702 all has 47.3 square feet base size.Between every row (for example capable r1 and row r2) of buoyancy pump equipment 1702, used 15.8 feet separation distance.
Further referring to Figure 17 A, be positioned at reservoir 17042 on the steep cliff napex 1718 to the water that receives from 1702 pumpings of buoyancy pump equipment by outlet line 1720.Water can be stored in the reservoir 1704 and be arranged in turbo machine (a plurality of turbo machine) (not shown) of turbo machine building 1724 by 1722 inflows of output supply line.Water can be discharged in the ocean 1708 once more via discharge pipe line 1726.In another embodiment, reservoir can be positioned at the top of water body, for example is positioned on the ship or on the oil platform.
Be appreciated that the buoyancy pump system can be designed to absorb fully nearly all process wave potential energy and to use power in the mode of this description and demonstration.Perhaps, the buoyancy pump system can be designed to the potential energy of the wave of absorption portion (for example, percent 50) process.These designs can utilize grid or other configuration in pump zone, but comprise buoyancy pump equipment in the location based on the some or all of skies that dispose.
Referring to Figure 18, comprise at least one buoyancy pump 1813 according to the buoyancy pump system 1811 of principle of the present invention, buoyancy pump 1813 has the reciprocating buoyancy block 1815 of response wave motion.Buoyancy block 1815 pumping operation fluids preferably use piston and the piston shaft that is similar to previously described system.Operating fluid is preferably water, is pumped to one of low reservoir 1821 and high reservoir 1823 from the locational offshore of buoyancy pump 1813.Preferably, but reservoir is positioned on the bank can places on the existing or new platform and offshore is placed.Low reservoir 1821 provides the water that receives pumping under the normal operation conditions of buoyancy pump 1813.Normal operation conditions usually occurs in the process of the wave height that has normal size, or in those wave heights that wherein buoyancy pump mainly is designed to operate.When the wave of bigger height arrived, buoyancy pump can utilize bigger wave height to come to generate higher pressure in operating fluid, therefore operating fluid is pumped in the high reservoir 1823.For pumping operation fluid under higher pressure (promptly higher than normal operation conditions pressure), the inner volume of buoyancy block must increase by the warpage process.The warpage process relates to height or the diameter that increases buoyancy block by previously described process (referring to Fig. 3 D-3F).When big wave occurring, the volume of the increase of buoyancy block can increase the pressure that is applied on the operating fluid, and keep with normal operation conditions process in the about identical flow velocity of flow velocity that generates.It is important to utilize the existence of higher wave height, because can use the operating fluid of storage in the reservoir (being high reservoir 1823) on higher height to generate electricity more efficiently.This mainly is because the turbo machine 1831 that is driven by the operating fluid that falls from reservoir can be operated by high pressure, low flow rates of fluid operation the time more efficiently, and this is opposite with low pressure, high flow rate fluid.Although above describing the design of using a plurality of reservoir for storage operating fluids with reference to two reservoirs of different heights, but those having ordinary skill in the art will appreciate that, this design can expand to and comprise that a large amount of reservoirs, each reservoir all are designed to can receive operating fluid in the wave appearance of certain height and in buoyancy block (via warpage) ideally when being adjusted to designated volume.
Referring to Figure 19, comprise at least one buoyancy pump 1913 according to the buoyancy pump system 1911 of principle of the present invention, buoyancy pump 1913 has the reciprocating buoyancy block 1915 of response wave motion.Because the big storm and the potential energy of hurricane in using the zone of buoyancy pump are so become too high and risk that remove from the seabed if buoyancy pump will be in wave height.Make this risk reduce to minimum, buoyancy block 1915 comprises the covered alternatively release port 1917 of permission buoyancy block 1915.When being submerged, buoyancy block can not apply any buoyancy (when perhaps flooding as fruit part, will applying less buoyancy) on the remainder of piston or buoyancy pump 1913, and this will prevent that buoyancy pump from removing from the seabed.Release port 1917 can be opened by valve that shows among Figure 19 and controller (not shown).Opening the signal of valve 1921 can be manual, long-range or the sensor of response measurement wave height, the hydraulic pressure adjacent with buoyancy block or the buoyancy that applied by buoyancy block and automatically providing.Replace to use valve to open and close release port 1917, release port 1917 can be by being bolted to for example stopper sealing in buoyancy pump stake or seabed of fixed structure.The bolt rigging has predetermined length, and buoyancy block will cause the bolt rope that stopper is removed from release port 1917 in the excessive amount of motion (for example responding big wave) of inside, buoyancy chamber like this, therefore floods buoyancy block.Except that release port 1917, buoyancy pump 1913 can comprise that the gas source 1931 of pressurization purifies buoyancy block after flooding operation.The gas of pressurization will be replaced the water in the buoyancy block, therefore allow buoyancy pump to return in the normal running.
The buoyancy block that comprises mainly the Mean length that is designed to the wave in " coupling " buoyancy pump operation region according to the buoyancy pump of principle of the present invention.Preferably, being dimensioned to it and enough coming the pumping operation fluid to generate big buoyancy greatly of buoyancy block with respect to wavelength, but obtain the energy of wave and do not exist the existence meeting of adjacent wave to reduce the process of obtaining energy significantly enough for a short time again.Preferably, the diameter of buoyancy block more than or equal to mean wave length about 1/6 and be less than or equal to about 1/2 of Mean length.Though not preferred usually, the diameter that buoyancy block can be designed to buoyancy block is the same with mean wave length big.
It is important also to point out, be preferably designed to when buoyancy block raises and reaches maximum height that about 1/3 volume of buoyancy block remains on the outside of water on mean wave according to the buoyancy block of principle of the present invention.The ability that the motion of wave (and so pumping operation fluid) is promptly followed in the complete submergence if buoyancy block becomes in each upward stroke, piece will weaken significantly.By allowing most of buoyancy block to remain on water outside, buoyancy block can promptly be followed the tracks of the motion of each wave and pumping operation fluid more efficiently.Certainly, the volume that floats over the buoyancy block of water outside will change in whole upward stroke, and can be higher or lower than 1/3 of total volume at the precise volumes of the water at the maximum point place of upward stroke.
Referring to Figure 26 to Figure 36, wherein show piston shaft 2115 in greater detail.Piston shaft 2115 comprises a plurality of nested pipes 2141,2143,2145, and these pipes are being connected on each end on the spherical accessory 2147.Manage 2141 diameter minimum and be nested in and manage in 2143, pipe 2143 is nested in pipe 2145 inside again.Each pipe comprises that all the internal thread that is positioned on each end is threadably to hold spherical accessory 2147.Spherical accessory 2147 comprises the axle 2149 of layering, and axle 2149 is made of little 2151, intermediate portion 2153 and big portion 2155.Big portion 2155 is connected on the spheric end 2159 rigidly.Little 2151, intermediate portion 2153 and big portion 2155 include outside thread.When piston shaft 2115 assemblings, one of spherical accessory 2147 is being connected on each end on the pipe 2141,2143,2145, so little 2155 conjugation tube 2141 threadably just, intermediate portion 2153 be conjugation tube 2143 threadably just, and big portion 2155 conjugation tube 2145 threadably.Spherical accessory 2147 helps to make pipe relative to each other fixing and guarantee to be applied to load allocating on the piston shaft 2115 to each all pipes 2141,2143,2145.The spheric end 2159 of spherical accessory 2147 is held by spherical joint 2165.First spherical joint is connected on the buoyancy block, and second spherical joint is connected on the piston.Spherical joint 2165 comprises cap 2167, and cap 2167 has the hemispherical groove 2169 that is used to hold spheric end 2159.The lock section 2175 of spherical joint 2165 is connected on the cap 2167 spheric end 2159 is fixed in the spherical joint 2165.Lock section 2175 comprises passage 2177, and passage 2177 has the part adjacent with conical region 2181 and is spherical land areas 2179.Spherical land areas 2179 is used for spheric end 2159 is locked in hemispherical groove 2169 inside.Conical region 2181 is outwards coming to a point when spherical land areas 2179 is extended gradually.Conical region allows piston shaft 2115 to rotate with respect to spherical joint 2165 around spheric end 2159, and the small angular motion of buoyancy block in the buoyancy chamber will not apply big reversing or bending force to piston shaft 2115 like this.The main angular motion of the buoyancy block 2113 that spherical joint 2165 is protected is those angular motions that center on perpendicular to the reciprocating axis of buoyancy block 2113.
Referring to Figure 37 to 39 and Figure 27, the angular motion of aforesaid buoyancy block 2113 is owing to existing at least one sliding support 2211 on the outer surface that is connected to buoyancy block 2113 to be reduced to minimum.Sliding support 2211 comprises guide channel 2215, and guide channel 2215 is oriented and receives the guide upright post of placing around the periphery of buoyancy chamber 2217.When buoyancy block 2113 during in buoyancy chamber's reciprocates inside, sliding support 2211 helps guiding buoyancy block 2113.Preferably, sliding support 2211 is made up of so that easier installation two separating part shown in Figure 38 and 39.Preferably, guide channel 2215 is lined with polymer material and reduces friction between sliding support 2211 and the guide upright post 2217.
Referring to Figure 21 to Figure 25, buoyancy pump 2111 uses a plurality of piled anchors fixed, and these structurally support other system of each platform, piston chamber, conduit and buoyancy pump 2111.Preferably, buoyancy pump 2111 comprises with equally isolated eight stakes of circular pattern (all skirt piles 2311), and additional newel 2313 is positioned at the center of circular pattern.Because the length of stake is longer relatively, and because stake is subjected to the power from pumping operation, ocean current, tide and wave action, so a plurality of cabane strut 2315 is connected between each all side column 2311 and the Center stake 2313.Each cabane strut 2315 includes the sleeve 2317 of each end that is positioned at cabane strut, and each sleeve holds a stake.Preferably, each sleeve is lined with polymer and prevents the contacting of metal and metal between cabane strut 2315 and the stake.Except that preventing stake excessive amount of motion (therefore making a hardening) relative to each other, cabane strut 2315 can add sizable weight to buoyancy pump 2111.The weight of cabane strut 2315 can greatly be assisted grappling buoyancy pump 2111, and when the portable buoyancy pump that for example uses as shown in Figure 21, this point is even more important.
Referring now to Figure 40-44,, wherein shown buoyancy pump 4011 according to principle of the present invention.All sizes that show with respect to these figure are property purpose and be not the scope that is used for limiting appended claims presented for purpose of illustration only all.Pump 4011 comprises buoyancy block 4013, and buoyancy block 4013 movably places buoyancy chamber 4014 and is connected on the upper piston 4017 and by lower piston axle 4025 by upper piston axle 4015 and is connected on the lower piston 4027.Buoyancy block 4013 responds wave action and to-and-fro motion.When buoyancy block 4013 raise on wave, lower piston 4027 raise, and the overflow of permission operating fluid is by inlet tube 4031 and enter lower piston chamber 4033.When reducing when buoyancy block 4013 response wave motions, lower piston 4027 is drained into the operating fluid in the lower piston chamber 4033 in the pipette 4039 by the weight-activated of buoyancy block 4013 and is drained into subsequently among the 404l of upper piston chamber.This in down stroke in buoyancy block 4013, upper piston 4017 moves down, and therefore allows to enter upper piston chamber 4041 from the operating fluid of pipette 4039.When buoyancy block 4013 moved up once more, piston 4017 was upwards driven being discharged in the outer pipe 4045 from the operating fluid of upper piston chamber 4041 by buoyancy.Safety check 4049 prevents to reflux by pipette 4039 from the operating fluid of upper piston chamber 541.
For the buoyancy pump 4011 shown in Figure 40-44, preferred operating fluid is a water, and the size of piston chamber and position need 60 feet suction head to fill piston chamber, and this can cause water generates foam or boiling.Prevent boiling, buoyancy pump 4011 of the present invention uses malleation that operating fluid is pushed in the upper piston chamber 4041, and is drawn in the upper piston chamber 4041 operating fluid opposite with using negative pressure.Malleation is by the generating to down stroke of lower piston 4027, and this is by the weight-activated of buoyancy block 4013.For this reason, buoyancy block 4013 can be designed to heavier than the buoyancy block that only is connected on the single piston.Certainly, if buoyancy block 4013 is heavier, it also is favourable that the displaced volume that increases buoyancy block 4013 to support extra weight when floating on the water.
Upper and lower piston shaft 4015,4025 comprises a plurality of nested pipes, and these pipes are being connected on each end on the spherical accessory 4057.Each pipe comprises that all the internal thread that is positioned on each end is threadably to receive spherical accessory 4057.Spherical accessory 4057 comprises the axle of layering, and this axle is made of little portion, intermediate portion and big portion.Big portion 2155 is connected on the spheric end 4059 rigidly.Little portion, intermediate portion and big portion include outside thread.When piston shaft 4015,4025 assemblings, one of spherical accessory 4057 just is connected on the pipe on each end, and so little portion, intermediate portion and big portion all engage with one of pipe.Spherical accessory 4057 helps to make pipe relative to each other fixing and guarantee to be applied to load allocating on the piston shaft 4015,4025 to each all pipes.The spheric end 4059 of spherical accessory 4057 is held by spherical joint 4065.Spherical joint 4065 is connected on each upper and lower surface of buoyancy block 4013, and spherical joint 4065 is also connected on each upper piston 4017 and the lower piston 4027.Spherical joint 4065 comprises the hemispherical groove that is used to hold spheric end 4059.Provide the sticking department of spherical joint 4065 to assign to spheric end 4059 is fixed in the spherical joint 4065.The configuration of spherical joint allows piston shaft 4015 to rotate with respect to spherical joint 4065 around spheric end 4059, and the small angular motion of buoyancy block in the buoyancy chamber will not apply big reversing or bending force to piston shaft 4015 like this.The main angular motion of the buoyancy block 4013 that spherical joint 4065 is protected is those angular motions that center on perpendicular to the reciprocating axis of buoyancy block 4013.
Owing to there is the sliding support 4111 at least one outer surface that is connected to buoyancy block 4013, so that the angular motion of aforesaid buoyancy block 4013 just is reduced to is minimum.Sliding support 4111 comprises guide channel, and this guide channel is oriented and receives the guide upright post of placing around the periphery of buoyancy chamber 4117.When buoyancy block 4013 in the buoyancy chamber during 4014 reciprocates inside, sliding support 4111 helps guiding buoyancy block 4013.Preferably, be lined with polymer material in the guide channel and reduce friction between sliding support 4111 and the guide upright post 4117.Owing to have upper piston axle 4015 and lower piston axle 4025, the angular motion of buoyancy block 4013 also can further be reduced to minimum.
