Description
Technical field
The present invention relates to a kind of energy conversion device, especially a kind of mechanical energy that wave is unordered is converted to the floating swing type wave energy conversion device of available kinetic energy or potential energy.
Background technique:
The ocean area takes up an area of 71% of ball surface, and wave can be the abundantest in the marine energy, the most general, inexhaustible, nexhaustible and than the most reliable resource of good utilisation.Wave energy is again the marine energy that accounts for the largest percentage in the ocean energy.The wave motion of seawater produces very huge energy, it is estimated, reaches more than 70,000,000,000 kilowatts than the wave energy that is easier to utilize in the world ocean, accounts for more than 94% of whole ocean energies.
China is a seashore line length, but the country that the wave availability is high, the density of maritime provinces such as Hainan Island, Taiwan and Fujian, Zhejiang, Guangdong, Guangxi, Shandong, Jiangsu, Liaoning and Xisha, marine site, Nansha Islands wave energy can reach 5～8kW/m (the wave energy density of the Atlantic Ocean, east coast, the Pacific Ocean is especially up to 50～70 kilowatts/meter).China coastal waters is controlled by monsoon, winter, wave was big, summer, wave was little, particularly winter is under strong northerly effect, form the billow band of a northeast to southwest trend from the Huanghai Sea to the South Sea, average unrestrained wave height is more than 2 meters, and the cycle is at 4-8 between second, help wave-energy power generation, have wide development and utilization prospects.
Wave energy is the renewable resources that cleans most, and its development and use will fundamentally be alleviated because the crisis that fossil energy is petered out improves because the destruction that the burning fossil energy causes environment.
Over more than 100 year, countries in the world scientist's unremitting effort has proposed the imagination of kind more than 300, has invented various wave energy generating sets.The wave-type electric generator of having researched and developed at present comparative maturity has following three classes basically:
The one, " wave pressurized air type ", with volume case fixing, that communicate with seawater, the water surface site variation that produces by wave causes that the air volume in the container changes, the air in the compression container, use the compressed air-driven impeller, drive the electricity generating device generating;
The 2nd, " mechanical compress liquid-type ", utilize the active part of the motion pushing device of wave: duck body, raft body, float etc., intermediate mediums such as active part compression (drivings) oil, water generate electricity by intermediate medium promotion electricity generating device.
The 3rd, " the wave savings is flow pattern down " utilized the contraction water channel that wave is at the incoming tide introduced elevated reservoir and formed water-head (head), the dirty direct driving hydraulic generator unit generating of utilized head.
Though these three types respectively have advantage, their common shortcomings are: 1, to convert the medium tache of electric energy to many for wave, and efficient is low, is not easy the formation scale; 2, can only partly utilize wave mechanical energy, can not absorb the cost of electricity-generating height to unordered, that disperse, low-density, unsettled wave energy; 3, sea wave energy conversion apparatus and structure thereof bear the ability of disastrous ocean climate, are not easy to resist the destruction of typhoon, tsunami, and potential safety hazard is bigger.This is the main difficult problem that current wave can develop.
The Western European countries such as nearest Britain have developed floating-tube type sea snake technology, they use several floating drums that are serially connected to ride on the wave, utilize the variation of the fluctuating slope angle of wave to promote the piston generating of floating drum, this mode really can be so that the anti-storm of system be strengthened, but because the fluctuating of wave itself is very mild in fact, angle changes also very little, and it is perpendicular to peak line, so wave that a string floating drum can only corresponding very little width, efficient is unsatisfactory, it is Anti-Typhoon, the ability of tsunami is also not enough, does not overcome above-mentioned shortcoming.
Because various technical problems, the seawave power generation cost is higher 10 times and have hidden danger than thermoelectric.
Want to improve the practicability level of seawave power generation, must solve the above-mentioned main difficult problem that prior art exists.
Summary of the invention
A kind of energy conversion device of providing in order to solve an above-mentioned difficult problem is provided, especially a kind of mechanism is simple, medium tache is few, security of operation, can wave is unordered mechanical energy be converted to the device of available kinetic energy or potential energy more fully, for the generating or the direct usefulness of acting.
The objective of the invention is to be achieved through the following technical solutions:
A kind of floating swing type wave energy conversion device, by the seabed fixed base, rock pillar, floating type adopt can device and transducer form, the workpiece that it is characterized in that transducer between floating type adopt can device with rock between the pillar, by gear drive or tension and compression elastic device realization transformation of energy.
The seabed fixed base is that a cardan shaft that can rock is connected with rocking between the pillar.
It can device be the big and container of hollow of a volume that floating type is adopted, and rocking that pillar runs through and exceed that floating type adopts can device.
The surface of rocking pillar has annular tooth, the power gear that is meshed with this tooth is fixed on floating type and adopts on the energy device, when floating type adopt can device top to bottom, left and right, front and rear when rocking, by the tooth of power gear and the effect between the annular tooth, the gear that drives transducer rotates.
One end that also can adopt reciprocating type transducer with rock the support arm that pillar stretches out and be connected, the other end and floating type are adopted the mode transducing that can device links to each other.
Floating type is adopted the weight modulator that water storehouse and may command seawater turnover water storehouse are housed on the energy device.
Floating swing type wave energy conversion device of the present invention has characteristics such as simple and reliable for structure, applied widely, that energy conversion rate is high, energy is anti-risk, cost is low.
Further specify below in conjunction with accompanying drawing
Fig. 1 is the structural representation of floating swing type wave energy conversion device of the present invention;
Fig. 2 drives the structural representation of power gear for annular tooth of rocking pillar of the present invention;
Among the figure: 1, seabed fixed base; 2, rock pillar; 3, floating type is adopted the energy device; 4, transducer; 4 ', the tension and compression transducer; 201, annular tooth; 202, rock the support arm of pillar; 301, water storehouse; 401, the tooth of power gear.
Embodiment
Referring to Fig. 1, floating swing type wave energy conversion device by seabed fixed base 1, rock pillar 2, floating type adopt can device 3 and transducer 4 form, the workpiece that it is characterized in that transducer 4 between floating type adopt can device 3 with rock between the pillar 2, by transmission device or tension and compression elastic device realization transformation of energy such as gear, tooth bars.
Because wave low, capricious disordered motion when high when being a kind of up and down, suddenly left, suddenly right, suddenly big or suddenly small, water level, therefore, to fully gather these energy, just must make wave fully act on an object acting, energy is passed to this object, and the simplest a kind of mode is to act on floating debris.Give work mechanism and prevent that floating debris from floating for the energy transfer that floating debris is obtained, the present invention is provided with seabed fixed base 1 and rocks pillar 2, and seabed fixed base 1 is that a cardan shaft that can rock is connected with rocking between the pillar 2.So just can make and rock pillar 2, prevent prop collapse, and the energy transfer that can rock displacement is given transducer 4 with the rocking and rock of floating debris.
