Description
Technical field
The present invention relates to a kind of with about the ocean tidal wave, front and back and about the unordered low-grade mechanical energy of low speed of the three-dimensional fluctuation ocean tidal wave three-dimensional energy that is converted to the high-grade energy utilize equipment, especially a kind of ocean tidal wave energy power generating equipment.
Background technique:
The ocean area takes up an area of more than 70% of ball surface, seawater in the ocean is owing to the difference that is subjected to lunar gravitation in different time sections, and flood tide and ebb tide all will twice every day, and tidal range is between 2 meters to 6 meters, sometimes even can reach more than 10 meters, little fluctuating wave when also big sometimes simultaneously.This morning and evening tides and wave have great energy.
Existing tidal power generation is that utilization contraction water channel is introduced elevated reservoir formation water-head (head) with wave at the incoming tide, and the dirty direct driving hydraulic generator unit of utilized head generates electricity again, and the energy of the morning and evening tides that utilizes is very little.
Wind acts on seawater can cause stormy waves, and the volcano eruption in earthquake and seabed etc. also can cause surge.Therefore, wave can be the abundantest in the earth energy, the most general, inexhaustible, nexhaustible and than the most reliable resource of good utilisation.Wave energy is again the bigger marine energy of proportion in the ocean energy.The wave motion of seawater produces very huge energy, and this energy fluctuates, rocks and spring up with fluctuation up and down, all around of seawater is the form of expression.It is estimated that the wave energy that is easier to utilize in the world ocean reaches more than hundred billion kilowatts.
Tidal energy and wave energy are the renewable resourcess 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.
In the past, people wave can and tidal energy regard unordered, dispersion, interruption, uncontrollable low speed, low-grade mechanical energy as, think to be not easy to utilize, utilize must make it in order through medium tache, concentrated, continuous, controlled, just can utilize after becoming high speed again.
Over more than 100 year, countries in the world scientist's unremitting effort has proposed hundreds of imaginations, has invented the various devices that utilize wave to generate electricity.Exploitation after deliberation at present, the Wave power generation device of comparative maturity also has following two classes except that above-mentioned tidal power generating device:

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 strong inadequately, does not overcome an above-mentioned difficult problem.
Because various technical problems, the seawave power generation cost is higher about 10 times and have potential safety hazard than thermoelectric at present.
Science and technology is not complicated more good more, antithesis, can solve people with the simplest equipment and method and think that always the problem that is not easy to solve is exactly a high-tech.Want to improve the practicability level of seawave power generation, must solve the above-mentioned main difficult problem that prior art exists, break away from the constraint of existing idea, cut down the number of intermediate links, utilize reliable apparatus simply and easily, adapt to the actual conditions of ocean wave motion, realize the conversion of ocean tidal wave three-dimensional energy.
