Description
Technical field
The present invention designs the device that a kind of wave energy is converted into electric energy, and this technology is that the mechanical energy that wave motion produces is converted into electric energy.The characteristics of technology are that apparatus structure is simple, and the reliability height is stable, the transformation efficiency height of wave energy, and anti-storm, corrosion resistance are strong etc.
Background technique
National economy all develops in continuous speedup every year, and correspondingly, the development of the speedup of this economy must cause the speedup to energy requirement, and is especially obvious to the increase of electricity needs.Existing generation mode mainly comprises thermal power generation, water power, nuclear power etc., because the exploitation of water power and nuclear power can be subjected to the restriction of many objective condition, ratio in the generated energy of entire society is also smaller, and thermal power generation has occupied the share more than 80% in China.But because thermal power generation need consume a large amount of fossil fuels, bring a large amount of emission of carbon-dioxide and serious environmental to pollute simultaneously.And fossil fuel in the near future will be exhausted on the earth, and people must be developed new as early as possible, cleaning, reproducible alternative energy source is to keep sound development human society and environment.Under this background, people have turned to wind energy and ocean energy with attention.Ocean energy lies among the ocean current and wave of ocean, and it is a kind of highly beneficial with the clean energy resource that is worth wherein wave energy being converted into electric energy.71% of sphere area is taken up an area of in the ocean, the ocean receives the energy that the sun brings in every way, a kind of form of the energy performance of these absorptions is exactly wave energy, wave is ubiquitous, and contained energy density is big, is 20 times of solar energy, be about 5 times of wind energy, can be described as a kind of good, inexhaustible energy source.At present, the mode that wave-energy power generation usually adopts has: 1, wave energy is converted into the hydraulic pressure energy, the turbo machine that promotes to be connected with generator rotates, and then makes generator rotate generating.2, wave energy is converted into mobile pressurized air, the turbo machine that promotes to be connected with generator rotates, and then makes generator rotate generating.3, wave energy is converted into mechanical energy, directly pushing generator rotates generating.Above-mentioned several wave energy generating set respectively has pluses and minuses, all has the demand that improves generating efficiency.
Temeev in the meeting of the 5th wave energy in Europe, people such as A. have proposed a kind of mode (Temeev, A. that can generate electricity with wave vibration drive a kind of wave that oil hydraulic pump-oil hydraulic motor generates electricity with spring suspension weight in floating drum, Antufyev, B., and Temeev, S.; " Simulation of Oscillatory Drive for Float Wave Energy Converter " Fifth European Wave Energy Conference Proceedings, Hydraulics﹠amp; Maritime Research Centre, Cork, Ireland, pp.386-391,2003.).This design has very high energy absorption efficiency, when the weight of floating drum with hang weight of heavy and approach, the vibration frequency of floating drum and weight and wave vibration frequency near the time, device can reach more than 90% to the absorption of wave energy, and be the absorption wave energy generating set of totally enclosed point, be conducive to improve electricity generating device anti-corrosion capability and capacity of anti-storm.But there is very big problem in this design, reach the wave energy absorption efficiency of theoretical design, should approach the period of vibration of weight with the period of vibration of wave, be example 4 seconds average periods with wave, the length that the leaves standstill when spring of the suspension weight that calculates does not have wave on the sea is about 4 meters, consider the stretching of vibration, what the amplitude of oscillation of weight can be very is big, designs such electricity generating device and has a lot of technical difficult problems.Meanwhile, because there is irreqularity in the vibration of wave, follow-up energy transmission hydraulic system can reduce energy transmission and transformation efficiency greatly because of hunting.
The present invention is directed to the problems referred to above, designed a novel wave energy electricity generating device, the ingenious weight of utilizing the electricity generating device equipment of itself, replace simple weight, this design has not only reduced the quality of whole generating equipment, has strengthened the electricity generating device of design to the servo-actuated property of wave.Because the spiral spring group has been installed in the weight that hangs, because the reverse energy storage effect of spiral spring group in vibration reduced the amplitude that weight vibrates, pendulum spring size and the excessive problem of oscillation amplitude have been overcome.And, owing to used the spiral spring buffering accumulated energy, avoided the irreqularity of vibration of wave and the influence to power generation system stable operation that causes.In a word, the device of the present invention design is optimized, reasonably integrated each core component of power generation with marine energy, makes each several part therefore can improve the generating efficiency of device greatly in the optimum state work.
Summary of the invention
The present invention has designed a totally enclosed type with the wave energy wave energy generating set, and it is wave energy to be converted into hang the energy that weight vibrates up and down, and the energy of this vibration is converted into the mechanical energy of rotation by mechanical device, drives generator for electricity generation.Shortcomings such as it is low to the absorption efficiency of wave energy that it can overcome similar device, and energy conversion efficiency is low, and electricity generating device and output electric energy are not steady.
Concrete technological scheme is as follows: a kind of with ocean energy, wave energy is converted to the device of mechanical energy or electric energy, a floating drum is arranged, also play the effect of loading, there is slide rail inside, at slide rail a weight is arranged, this weight is by two or two groups of springs are suspended on floating drum inside up and down, above the weight one group with the inner top of floating drum on be connected, one group of spring below the weight is connected with the floating drum bottom, the difference of spring strength is that weight is on the intermediate point of vibration up and down, the summation of top spring tension is that following spring tension summation adds weight gravity, weight is stressed balanced up and down in this case, and oscillation frequency is more close to self natural oscillation frequency, thereby can be by regulating the quality of weight, it is consistent with the wave frequency to make it the nature oscillation frequency, or approximately less than the oscillation frequency of wave.Because weight is to be suspended on floating drum inside by spring, when floating drum vibrates up and down with wave, weight also can move thereupon, but weight can produce a phase difference that moves with floating drum because of inertia, produce a relative movement, this relative movement just can be with the follow-up unit transmission to electricity generating device of the wave energy that absorbs.Weight is in the process of vibrating up and down with wave, in that to depart from equinoctial point more far away, it is just more strong to the reaction force of spring to be subjected to folk prescription, and vibration all can be subjected to the reaction force of spring up and down, thereby the vibration width of weight just is restricted, overcome a difficult problem that needs very long pendulum spring, and this hang, make weight strengthen greatly with the servo-actuated property of wave vibration, do not have the oscillation frequency of weight and situation that the wave frequency has bigger difference and occur, thereby can absorb ocean energy efficiently.This weight is actually the part of electricity generating device, is made up of single load bearing gear train, spiral spring, gear speed control system and generator.The single load bearing gear train is by a pair of single load bearing gear, and the chain of a pair of tumbler gear and a pair of closure on single load bearing gear and tumbler gear constitutes.One side of this a pair of gear bar is again by on the force rod that a force bearing point is fixed on floating drum is connected.When the suspension weight vibrates up and down, produced relative movement between weight and the force rod, because a side of gear bar is fixed on the force rod, this relative movement just makes the gear bar single load bearing gear produced the pulling force of a side, make the single load bearing gear rotate, rotate thereby drive the spiral spring central shaft, therefore wave energy transforms the mechanical energy in order to rotate, the input spiral spring.Because force rod and being connected of two gear bars are the not homonymies at two gear bars, article two, the gear bar is opposite to the direction of pull of two single load bearing gears, so no matter weight is upwards or moves downward, two single load bearing gears remain an opposite sense of rotation, its result has only one can drive the rotation of spiral spring central shaft all the time in two single load bearing gears, and be fixing turning to, the wave energy that this structure just constantly changes direction has changed into folk prescription to the mechanical energy of rotating.The effect of spiral spring does not only absorb the energy of relative movement input, it carries out buffer memory, buffering to the wave energy that absorbs the continuous fluctuation of size of coming in, make the mechanical energy that becomes smooth rotation through the energy behind the spiral spring, be transferred to the generator in downstream, send stable, the electric energy that can effectively utilize.The spiral spring group has been installed in the weight that hangs, because the reverse energy storage effect of spiral spring group in vibration also reduced the amplitude that weight vibrates, has helped to have overcome pendulum spring size and the excessive problem of oscillation amplitude.

Specific embodiments
Below in conjunction with accompanying drawing embodiment of the present invention are elaborated
The a kind of of design of the present invention is converted to the device of mechanical energy and electric energy with ocean energy, wave energy, and referring to Fig. 1, Fig. 2, by floating drum 1, pendulum spring group 2 hangs weight 3, weight slide rail 4, and force rod 5 critical pieces such as grade constitute.Wherein weight 3 is cores of this electricity generating device, it (comprises single load bearing gear 9 by the single load bearing gear train, gear bar 10, reverse wheel 11), the reception of spiral spring energy, buffering, caching system (comprising spiral spring 7, spiral spring central shaft 8 and energy output gear 13), gear speed control system (gear train 14), generator 15 formations such as grade.This be one totally enclosed, the floating absorption wave energy generating set of point across the sea, fixing by anchor chain 17.This device floats on the sea, follows wave and makes rippling down, and the suspension weight 3 of floating drum 1 inside relies on slide rail 4 moving thereupon under the pulling of cluster spring 2,2a, and the weight vibration range is subjected to the restriction of resistance device 6.Because the inertia of weight, produced the phase difference of a motion between it and floating drum, phase difference has caused relative movement, relative movement is by force bearing point 12, the gear bar 10 pulling single load bearing gears 9 that are fixed on the force rod 5 are rotated, therefore wave energy has inputed to spiral spring group 7 with regard to having changed into the mechanical energy of rotating, this mechanical energy is buffer memory in spiral spring group 7, after the buffering, pass to follow-up timing gear wheels 14 through energy output gear 13, through speed governing or input generator 15, produce and effectively to utilize, electric energy is got involved the land electrical network by cable 16 stably.
Two groups of cluster spring 2 have up and down been adopted in the device of the present invention's design, 2a hangs the design of weight, its characteristics are that weight cluster spring up and down has more than two, on the position of equinoctial point, the distance that stretches of cluster spring equates up and down, above the pulling force of one group of spring making a concerted effort of equaling that the torsion of quality, the spiral spring of pulling force, the weight of following one group of spring produces together.The amplitude of weight and period of vibration are to regulate by the quality of regulating weight and the pulling force of spring, make it the vibrational period close to the vibrational period of wave, also can be only with one group of top spring 2, what pulling force of this group spring will equal that the torsion of the gravity of weight and spiral spring group produces in the central position of weight vibration so makes a concerted effort, to guarantee that weight can keep with floating drum consistent oscillation frequency being arranged.
The vibration weight 3 of the present invention design has comprised a plurality of requisite functional part in the electricity generating device, and purpose is that this design except can the several functional parts of optimum organization, have also effectively utilized the inner space of electricity generating device.Another very important effect is exactly the overall weight that has reduced whole device, has improved the response sensitivity of electricity generating device to wave, makes device can better keep the oscillation frequency consistent with wave.This is because if the functional part that will hang in the weight 3 changes simple weight into, the functional part of changing just can only be fixed on the floating drum, thereby just increased the weight of floating drum part, theoretically, the weight of floating drum approaches the wave energy absorption efficiency that just can reach high with suspension weight quality, increased the weight of floating drum, will use the suspension weight of bigger quality, thereby increased the weight of whole device greatly, the increase of device gross weight, inertia also increases thereupon, thereby has reduced the speed of response of device to wave, has reduced the absorption efficiency of device to wave energy on the contrary.
Designed novel single load bearing gear train (referring to Fig. 3) among the present invention, played the mechanical energy that the wave energy that comes and goes rising and falling is converted into unidirectional rotation, this device is simple and reliable, can effectively improve the transformation efficiency of wave energy.
The spiral spring group (referring to Fig. 4) of the present invention's design has the function of buffer memory and buffering energy, this device is when being used for power generation with marine energy, reversing of spiral spring group, stretching is a kind of process of energy buffer memory, its advantage is when the energy of extraneous input is excessive when arriving as billow, and when downstream energy conversion capability can not mate or lag behind, the spiral spring group was passed through to twist, the energy buffer memory is got up in stretching, discharges when the low ebb of wave.Another situation is extraneous input energy when very little, does not reach the minimum input energy of energy conversion device design, and the spiral spring group can play the effect of tired energy collecting, discharges to give the energy converting apparatus after reaching certain energy.Because the size of wave energy is capricious, after so wave energy is converted into mechanical energy, moment by central shaft 8 input cluster spring is also constantly changing, because the scalability of spring, it can produce with input torque mutually the equity the moment of reaction, and this moment of reaction can be all the time being kept equity with input torque, this effect can be so that the power generation with marine energy device reaches peak efficiency to the absorption of ocean energy.The characteristics of wave energy are exactly its erratic behavior, this erratic behavior has caused the poor efficiency of follow-up energy conversion system, the spiral spring group is assembled in the vibration weight 3, dissolved the irreqularity of wave energy, the influence that makes downstream energy transformation system not can fluctuate by wave, the upstream energy absorber system of spiral spring is not subjected to the influence of upstream device yet, thereby has improved stability and the energy conversion efficiency of whole generating device.Generally speaking, the energy buffer memory of this spiral spring group, buffer function, the energy reception of wave energy generating set and the scope of utilizing have been enlarged, make energy absorption and transform more effectively, also make wave energy generating set that this spiral spring group energy buffer memory and transfer unit are installed that the adaptive capacity of sea situation is strengthened simultaneously.Moreover, this device can make the energy that is transferred to energy conversion device more even, thereby the electric current of generator generation, voltage all can be more stable, therefore with the part of spiral spring group design and installation for suspension weight 3, can effectively avoid system's unreliability of mechanical transmission power generation with marine energy device in the past.Spring number in this spiral spring group can be one, also can be a plurality of, the intensity of spring, and size can be adjusted as the case may be.The various parameters of whole spiral spring group energy buffer memory and transfer unit can be adjusted as the case may be.A spiral spring group can be arranged in the whole wave energy generating set, also can have a plurality of parallel connections or series connection, perhaps in parallel, the simultaneous a plurality of spiral spring groups of series connection reach optimum efficiency in the hope of absorption and the conversion that makes energy.
In the electricity generating device of the present invention, the phase difference that utilizes spring mounted weight 3 to produce in vibration absorbs and transmits wave energy, after spiral spring in the weight 3 has absorbed energy, come speed governing and transmission energy by gear, be transferred to generator for electricity generation at last, so whole system is a mechanically operated electricity generating device, the conversion of twice form of energy has not been passed through in the energy transmission as hydraulicdriven power generation with marine energy device, and energy conversion efficiency is higher.
The wave energy generating set of the present invention's design, it is wideer to have endergonic scope, the efficient of harvest energy is higher, adaptive capacity to sea situation is stronger, the electric energy of output is more stable, overcome generator stall, unsettled shortcoming that mechanical transmission power generation with marine energy device occurs, can also reduce the cost of wave-energy power generation greatly.These advantages have determined wave energy generating set disclosed by the invention that wide application prospect is arranged.
The single load bearing gear train that comprises in the suspension weight of the present invention's design, play wave energy up and down reciprocatingly is converted into the mechanical energy that single direction rotates, the structural design of narrating previously is a kind of more typical design method, but not unique method, also can change the gear of two single load bearings into wheel disc, driven by the wire rope of fixing up and down at floating drum, the structure of design is varied, key of the present invention is this conversion system design to have played the effect that receives and transmit energy for the power generation system that hangs in the weight in the weight 3 that hangs.
