[embodiment]

The present invention is described in detail below in conjunction with accompanying drawing:

The generator unit device, it is arranged on the buoy, and it includes generator unit shell 1, in generator unit shell 1, be provided with guide rod 2 and along the inertial mass body 3 of guide rod 2 upper and lower slips, in the present embodiment, the quantity of guide rod 2 can have about the 3-4 root, is generally 3.Be provided with the cavity container 31 that can store water and make its weight change in inertial mass body 3 inside, water injected cavity container 31 weight of inertial mass body 3 is changed.

Upper/lower terminal in described generator unit shell 1 inside correspondingly is provided with the extension spring 4 and the pressure spring 5 that can make inertial mass body 3 unsettled.The lower end of extension spring 4 is connected to the upper surface of inertial mass body 3, and the upper end of pressure spring 5 is connected to the lower surface of inertial mass body 3.Under the supporting effect of the drawing of extension spring 4 and pressure spring 5, make inertial mass body 3 unsettled and under the guide function of guide rod 2, make its upper and lower slip.

In generator unit shell 1, be provided with ratch 71, on inertial mass body 3, be provided with uni-drive gear box 72, the gear 721 of uni-drive gear box 72 input ends and ratch 71 engagements, the output terminal of uni-drive gear box 72 is connected with 6 in generator.Described uni-drive gear box 72 is an accelerating gearbox, and accelerating gearbox makes lumpy quick that generator 6 needs that become at a slow speed.

Be provided with the cavity container 31 that can store water and make its weight change in inertial mass body 3 inside, in generator unit shell 1, be provided with and regulate water pump 101, regulate water pump 101 and be connected with intake pipe 102 and outlet pipe 103, the outlet of intake pipe 102 and outlet pipe 103 places in the cavity container 31.Adjusting water pump 101 can inject water in the cavity container 31 or with water by intake pipe 102 and outlet pipe 103 and extract cavity container 31 out like this, thereby the quality of whole inertial mass body 3 is changed.

Also be provided with power transformation control box 8 in generator unit shell 1, the generating output terminal of generator 6 is electrically connected in the power transformation control box 8 and by power transformation control box 8 and carries out electric power output.

Why the present invention can generate electricity efficiently, and its working principle is:

When buoy during, be fixed on generator unit in the buoy and also follow and move up and down in wave mesorelief campaign.Because the inertial mass body 3 in the generator unit is only by extension spring 4 and pressure spring 5 drawings and support, has very large 'inertia', inertial mass body 3 does not follow buoy or generator unit shell 1 moves and the own original spatial position of maintenance, the extension spring 4 of generator unit inside and pressure spring 5 have been produced the potential energy of spring by " stretching " and " compression " distortion as a result.As seen, heaving of the sea makes spring absorb " potential energy " of wave.

At this moment, absorbed the extension spring 4 of wave potential energy and pressure spring 5 with equidirectional make a concerted effort release energy, promote the inertial mass body motion, ratch 71 and accelerating gearbox 72 by the centre have driven generator 6 generatings.

Regulating under the water pump help, the gross weight of inertial mass body is followed the change of wave period and is changed, and the natural period of oscillation of the elastic system that constitutes with two springs is followed the tracks of and the maintenance wave period, is in resonant condition.

In fact the phugoid motion speed of wave is slower, dislikes rotating speed too slow if directly drive generator 6, and generating efficiency is very low; So must improve rotating speed through an accelerating gearbox 72, just can obtain desirable generating effect.

As seen, the transformation of energy block diagram of above-mentioned principle reflection is as shown below:

Energy conversion efficiency is analyzed: generating working principle of the present invention is simple, and the link of transformation of energy is few, as long as carry out the design of each parts, the efficient of transformation of energy is high.

A in the above-mentioned block diagram, B, each transformation of energy condition of C, we see that A point energy loss is very little, when it is extension spring 4 and pressure spring 5 distortion " shear loss ", temporarily ignore because loss is too little.

The loss that B is ordered appears at wave periodic relief rhythm and cancelling each other that elastic system natural period rhythm does not conform to.This is a most important parts among the present invention.Finishing this Calculation Method is: according to the addressing of wave-activated power generation, understand " the normal encounter period " in local marine site, the natural period of design flexibility system meets this normal encounter period, because the cycle, identical energy produced " resonance ", make generator unit obtain very big energy, this guarantees long-term normal power generation.According to $f=1/t=\frac{1}{2\mathrm{\π}\sqrt{m/k}}$ The vibration frequency formula, m is the coasting body quality, k is spring constant (rigidity), π is a Ratio of the circumference of a circle to its diameter, vibrational period t is chosen as the period of waves of wave, just can make it produce resonance, make pouring weight obtain very big Oscillation Amplitude, greatly promoted and absorbed the effect that Wave energy is supplied with generating, if " the normal encounter period " in local marine site is when changing, at this moment can change the quality of m, i.e. the quality of inertial mass body 3 is injected water in the cavity container 31 or is extracted water out cavity container 31 and can realize by regulating water pump 101.Also have the vibration frequency of the vibration frequency of described extension spring 4, pressure spring 5 and inertial mass body 3 and wave identical, make it produce resonance effect.Described extension spring 4, pressure spring 5 meet worker's formula with the vibration frequency of inertial mass body 3: $f=\frac{1}{2\mathrm{\π}\sqrt{m/k}}.$

The loss that C is ordered is general electromechanical efficiency problem, is generally understood as more than 80%.

More than analyze, the efficient of this wave-activated power generation unit is very high, with international wave-activated power generation principle relatively, save the energy loss that the method for one " water wheels unit " or other transformation of energy is brought significantly.From economic implications, this electricity generating plan is also saved.

This generator unit also can horizontal positioned use, and this wave-activated power generation at offshore is very distinctive.

So-called " fragmentation " phenomenon that at first to be wave occur when bank far away is delivered to offshore, reason are the seabeds has resistance to the propagation of wave, and the waveform of wave just turns forward: the water surface is fast, and is slow under water, until the waveform very big variation of generation and fragmentation.The result of wave breaking makes the energy of nearshore wave impact to the bank with the form of wave stream, and is very strong to coastal offshore collapsing force under the typhoon situation especially.If set up wave power plant,, be that good effect is arranged through appropriate addressing and scientific design electricity generating device.

The generator unit horizontal positioned, make generator unit change horizontal positioned into simply, just can absorb the Wave energy of " level " direction by vertical placement.But, change the shell of this generator unit into square or triangle, and guide rail should be a ball bearing for long-term work and generating efficiency height better.This change is easy, and its working principle is constant.
