Description
Technical field
The utility model relates to a kind of device that utilizes ocean wave energy for generating electricity, particularly relates to a kind of float unusual fluctuation formula wave-type electric generator, belongs to the novel renewable energy technical field.
Background technique
Along with the development of World Economics, the surge of population, the progress of society, human growing to the demand of the energy.Human exploitation for traditional energy is faced with stern challenge.The development cost of traditional energy are day by day rare and become more expensive along with resource, and along with the mankind's continuous consumption, and world's main energy sources development period is very few: oil, rock gas and uranium are approximately 30-40, and coal is about 200 years.People have to turn to the developmental research of marine field to go to seek new development space.Containing rich in natural resources in the ocean, the again intensification of energy science and marine technology has been opened up new approach for solving this global energy and environment problem.Wave-activated power generation is subject to the attention of countries in the world as a kind of source of new energy.There are 18000 kilometers shore line, more than 300 ten thousand square kilometres seas under its jurisdiction in China, and marine resources are very abundant, and wherein, the reserves of territory, coastal waters wave energy are about 1.5 hundred million kilowatts, can development and use measure about 3000 ~ 3,500 ten thousand kilowatts.The device of wave power utilization is of a great variety, and is hundreds and thousands of about the patent of invention of Wave energy converter.
Under above-mentioned background, the development and use of wave energy receive publicity just day by day, through 20 century 70s the test and study of multiple wave energy apparatus is studied to sea situation test and the application demonstration of the eighties, lot of domestic and international scholar has proposed a lot of different types of Wave energy converters in succession, and the wave-activated power generation technology is progressively near practical level.Most study, most widely used several devices are at present: " duck nods " formula Wave energy converter, oscillaton water column type wave power device, swinging type wave energy device, poly-ripple reservoir wave power device, oscillating float type Wave energy converter.
The kinetic pressure that is subjected to the motion of energy body mainly to come from incoming wave motion generation of " duck nods " formula Wave energy converter promotes the duck body and rotates around axis, and static pressure promotion duckbilled is done the motion that rises and falls.Because the motion of two kinds of forms is synchronous, therefore the energy that produces can be passed simultaneously, use thereby be converted to again electric energy.Thereby advantage is to regulate duck body barycenter can make identical with the wave motion frequency or the approaching formation resonance of its free frequency, reaches maximum conversion efficiency; Shortcoming is that reliability is relatively poor, installs fragile.
The oscillaton water column type wave power device is that its one-level energy transfer mechanism is air chamber with the medium of air as conversion, and the secondary energy transfer mechanism is air turbine.The advantage of oscillating water column wave power device be rotating mechanism not with contact with sea water, antiseptic property is good, and is safe and reliable, easy to maintenance.Its shortcoming is that the secondary energy conversion efficiency is lower.Existing oscillaton water column type wave energy collection and conversion device is multiplex in the power supply of the miniature power equipments such as navigation mark light, and output power is less; Offshore oscillaton water column type wave energy collection and conversion device is had relatively high expectations to coastal landform.
The swinging type wave energy device is the front and back that occur under the effect of wave force by pendulum mass or swings up and down, wave energy is converted to the kinetic energy of balance staff.The transformation efficiency of pendulum-type device is high, but the maintenance of machinery and hydraulic mechanism is comparatively difficult.Its another advantage is to combine with phase control technology easily.Phase control technology can make wave power device absorb device and meet wave width wave energy in addition, thereby greatly improves the conversion efficiency of device.
Poly-ripple theory is proposed by Falnes and the Budal of Norway Te Longmu university the earliest.Poly-ripple reservoir device utilizes the contraction radio frequency channel of horn shape, as the one-level energy transfer mechanism.Radio frequency channel is wide with the opening that the sea is communicated with, and then shrinks gradually to pass to water-storage reservoir.Its advantage is that the one-level conversion does not have movable part, good reliability, and maintenance cost is low, and system exerts oneself stable, is subjected to hardly the impact in wave height and cycle.Deficiency is that the power station construction has requirement to landform, is difficult for promoting.
The oscillating float type wave power device is the Wave energy electric generator that grows up on the basis of oscillaton water column type device.Device converts wave energy to the reciprocating machine energy that drives oil hydraulic pump by oscillating floater, convert unsettled hydraulic energy to stable hydraulic energy by the energy snubber district again, convert stable hydraulic energy to stable rotating mechanical energy by oil hydraulic motor, send stable electric energy by generator again.Its advantage is to have reduced underwater construction, builds easily, and with low cost, the shortcoming float is subjected to too much impact, and is fragile.
These wave-type electric generators respectively have pluses and minuses, and key technology is middle conversion equipment, but there have a common problem to be that wave energy converts the medium tache of electric energy to be many, efficient is low, and the electric power output fluctuation is large, and this also is to affect the one of the main reasons that wave-activated power generation large-scale develops and utilizes.Disperse, low-density, unsettled wave energy absorbing gets up, concentrate, economical, efficiently, practicably be converted into useful electric energy, device and structure thereof can bear the destruction of disastrous ocean climate, realize safe operation, are a difficult problem and the directions of current wave energy exploitation.Above-mentioned technique device all adopts tertiary circulation to save wave energy is changed, be subjected to the energy body directly to accept the energy that from wave, transmits, decide body by be subjected to can body the caused by relative motion energy, and the intermediate conversion device, it mainly plays a part steady to, speedup and speed stabilizing in the wave conversion equipment, but several Wave energy converters in sum, the secondary conversion ratio of energy is lower.
