Description
Technical field
The present invention relates to a kind of energy conversion device, especially a kind of mechanical energy that shore wave is unordered is converted to the 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, the wave is high, summer, wave was little, particularly winter is under strong northerly effect, form the billow band of a northeast to the southwest trend from the Huanghai Sea to the South Sea, average unrestrained wave height is more than 2 meters, and the cycle is between 4-8s, 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 the crisis that fossil energy is petered out, and 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 wave energy, must solve the above-mentioned main difficult problem that prior art exists.
Summary of the invention
The objective of the invention is a kind of energy conversion device of proposing in order to solve an above-mentioned difficult problem, especially a kind of mechanism is simple, medium tache is few, security of operation, can shore 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 shore wave energy conversion device, form by transverse shakiness pillar, floating energy device, energy transmission device and the transducer adopted, an end that it is characterized in that the transverse shakiness pillar can be connected and fixed by the sea with rocking, the other end runs through the floating energy device of adopting, energy transmission device is adopted between energy device and the enegrgy converter floating, under the guiding of rocking pillar the Wave energy that obtains is passed to transducer.
Floating adopting can device be a floatable hollow container, can on the device tubulose sliding channel be arranged floating adopting, and the free-end of transverse shakiness pillar runs through wherein.
Energy transmission device is adopted between energy device and the transducer floating for around the rigid objects that rocks pillar, plays the energy transfer effect.
The transverse shakiness pillar is a smooth pillar, and its length can device offshore distance greater than floating adopting.
Floating adopting can have water storehouse and water inlet and outlet control gear on the device, can when hazard weathers such as typhoon, tsunami occur, it can be sunk to the seabed according to the size adjustment turnover water yield of Wave energy.
Shore 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.
