Description of drawings:

Further specify the present invention below in conjunction with the drawings and specific embodiments.

Fig. 1 is the side isometric view of Wave power generation equipment of the present invention.

Fig. 2 is the plan view of Wave power generation equipment of the present invention.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.

Principle of the present invention is that the energy of wave is introduced, and changes into mechanical energy, drives DC generator by mechanical energy again, changes into electric energy.

The operation of DC generator by generator drive gear G (H) transmission raising speed gearbox, is connected with generator coaxle by the raising speed gearbox again, realizes the working state of generating.

Use the 10mm thickness steel plate, make the rectangle of about 1/10th field pitch sizes, hollow pontoon, like a ship that floats on the sea, waviness is done in the floating drum bottom, and the order point is to amplify the bottom useful area, is held up by wave easily.Can ceaselessly swing up and down with the fluctuating of wave.

The Mass Calculation of floating drum:

Calculate the volume of the used steel plate of floating drum earlier:

$2\×(11M\×7M\×0.01M)+(4M\×7M\×0.01M)+2\×[(\frac{1}{2}\×$

$4M+0.5M)\×11M\×0.01M]$

$=2\×\left({0.77M}^3\right)+\left({0.28M}^3\right)+2\×[2.25M\×11M\×0.01M]$

$=1.54{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3+0.28{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3+0.495{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3$

$=2.315{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3$

Looking into iron and steel density is: 7800 kilograms/M ³

The quality of floating drum is: m=pv=7800 kilogram/M ³* 2.315M ³

=18057 kilograms

=18.05 tons

The volume of floating drum is: $11M\&times;7M\&times;(\frac{1}{2}\&times;4M+0.5M)=173.25{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3$

Floating drum is when state of rest, and emersion sea part accounts for 3/5ths of whole volumes, and the suffered buoyancy of floating drum this moment is:

The volume of underwater portion is $173.25{\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3\&times;(1-\frac{3}{5})={69.3\mathrm{<figure-callout\; id="3"\; label="M"\; filenames="A200710172302E00081.png"\; state="\{\{state\}\}">M</figure-callout>}}^3$

According to Archimedes' principle, can calculate the buoyancy of floating drum in seawater, at this moment the volume V of pontoon string boiling water _Row=69.3M ³Table look-up, the density of seawater is as can be known: r _Seawater=1030 kilograms/M ³

So the buoyancy that floating drum is subjected to is:

F _Floating=r _Seawater* V _Row* g=1030 kilogram/M ³* 69.3M ³* 9.8 Ns/kilogram

=0.699514 * 10 ⁶Ox

Referring to Fig. 1, Fig. 2, be subjected to the floating drum of so big buoyancy, the swing that goes round and begins again just can make full use of Wave energy.Steel plate floating drum C1, C2, C3 end are made thick connecting rod by the steel plate of 20mm thickness, and it relies on fulcrum roller D1, D2, D3 is the center of circle.Its D2 connecting rod drives huge gear F, and again by the driving gear G of No. 1 generator of F gearwheel transmission and the driving gear H of No. 2 generators, the huge gear F of wave drive just carries out the generating running of one drag two.The setting of D1 and D3 connecting rod is the wave holder power that overcomes from left side or right side, in order to avoid turn round the proper functioning that bad D2 is the gearwheel in the center of circle.The rotation of generator driving gear G and H, again by the raising speed gearbox of coaxial connection by coaxial connection DC generator, to reach the rotating speed that generator must reach.

Speed adjustable range: when the input shaft rotating speed is constant, the ratio of the maximum value of output shaft rotating speed and minimum value:

Promptly $R_b=\frac{{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="A200710172302E00081.png,A200710172302E00091.png"\; state="\{\{state\}\}">m</figure-callout>}}_2\mathrm{<figure-callout\; id="2"\; label="max\; m"\; filenames="A200710172302E00081.png,A200710172302E00091.png"\; state="\{\{state\}\}">max</figure-callout>}}{m_{}}=\frac{i\max }{i\min }$

When input shaft reached output shaft, the limit speed ratio of raising speed and reduction of speed was identical, for example: when the input shaft rotating speed during at 720r/min the output shaft rotating speed be: 295～1770r/min, at this moment speed adjustable range

Promptly $R_b=\frac{{\mathrm{<figure-callout\; id="2"\; label="m"\; filenames="A200710172302E00081.png,A200710172302E00091.png"\; state="\{\{state\}\}">m</figure-callout>}}_2\mathrm{<figure-callout\; id="2"\; label="max\; m"\; filenames="A200710172302E00081.png,A200710172302E00091.png"\; state="\{\{state\}\}">max</figure-callout>}}{m_{}}=\frac{1770}{295}=6$ Be that speed adjustable range is 6:1.

As everyone knows, the rotating speed of motor:

$n=\frac{60f}{p}\cos \mathrm{\&phi;}$ In the formula of the left side

Rotation speed n mains frequency f 60 is constants, the motor number of pole-pairs: the p power factor is cos φ.

As seen, the power supply grid quality of power supply needs to keep exchanging 50 hertz alternate electric energy.

Gearwheel F drives No. 1 generator gear G, and No. 2 generator gear H, realizes first order raising speed, again by the raising speed gearbox, realizes second level raising speed, reaches the rotating speed requirement of DC generator.The present invention carries out the setting of instrument monitoring and control and power transmission and distribution switch to the motion of DC generator, the electric energy that DC generator is sent charges to storage battery earlier, to the electric energy process inverter of storage battery, become dc inverter the Ac of 50 hertz of interchanges to carry and incorporate AC network into then.And popularization and application gradually, replacing the thermal power plant then is purpose.

Application of the present invention can reduce the sulfur dioxide (SO in thermal power plant ₂) and nitrogen oxide (NO _x) and the discharging of sulphide dust, with clean air with improve the greenhouse effect of the earth.

The present invention is in specific implementation process, should consider that seawater contains various salinities,, seawater is an occurring in nature saliferous quantity maximum, and the very strong natural electrolyte of corrosivity, metal and alloy commonly used can be corroded in seawater mostly, usually seawater is regarded 3% or 3.1% NaCL solution approx as, and institute thinks and prevents seawater corrosion, must carry out the processing of rust proof paint to floating drum, in the rust resisting paint, the resistance to corrosion seawater of epoxy paint, chlorinated rubber paint and vinyl lacquer is better.Transmission fulcrum and gear engagement surface for transmission shaft D1, D2, D3 need apply curing aluminium ointment lubricating as equipment.

In the floating drum cavity, suitably put a little steel ball workers, purpose is to allow floating drum B end appropriateness be upturned, do not wish that again steel ball rolls in the floating drum chamber, so in the floating drum chamber, be a dividing plate K, the position (this is designed to the petty patent in the big patent) that limits steel ball at floating drum C end, is opened Yishanmen M in order to allow the workman pass in and out in the floating drum chamber.After debugging finished, door M need close, and door M need have rubber weather strip, in order to avoid seawater flows into.

More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
