Abstract
A sea wave power machine possesses a core portion consisting of four bevel gears which are mutually meshed together, said core portion is connected together with floats by means of flywheels and rockers, two rockers are connected on one float. When the sea wave rises and falls, the float is also resin and fallen with it so that the transmission of every pair of rocker and flywheel can make the output shaft of said power machine always output a moment rotating toward same direction. The more number of floats, the larger moment output by power machine, and the more quick and stable the rotating speed of the output shaft. It the large and small chain wheels are substituted for levers, and the chain can be substituted for connecting rod, its effect can be better.
Description
Ocean wave power machine is by forming with the bottom, as shown in Figure 1.
The core: it is to be made of with 1,2,3,4 four engaged angular wheels together to represent that wherein 1 is output wheel or axle.
The flywheel part: it can play and rotate to a direction is stuck, is the effect of sliding and rotate to another direction.Use F
1-F
1' expression.
The rocking bar part: they couple together by flywheel and arbor, and specialization is that the end of two rocking bars connects together, and fastens on same float.Use A

1' expression.
The float part: it is placed on the water surface, with the wave dipping and heaving, represents with alphabetical D.
Counterweight part: keeping rocking bar with it is both sides, center balance with the arbor, uses P
1-P
1' expression.
The operating principle of ocean wave power machine: when wave rose, float D also rose thereupon, drove rocking bar A by hinge C

4Rotate with angular wheel 4 inhour, so drive output gear 1 rotates from bottom to top (axially look is the inhour rotation) at this moment angular wheel 4 are driving wheels.
When wave fell, the weight of float dependence itself also fell thereupon, pulling rocking bar A
1-A
1' clockwise rotate flywheel F at this moment

2Clockwise rotate with angular wheel 2, so drive output gear 1 rotates from bottom to top (being the inhour rotation from axially looking) at this moment angular wheel 2 are driving wheels.
From the above analysis, our this mechanism of invention is feasible, no matter wave is to rise or the whereabouts, machine is exported the moment of an equidirectional rotation all the time, the fluctuating that wave does not stop, power engine are just constantly rotated continuously, the blank of simple ocean wave power machine that Here it is.
From the action principle analysis, can't see the effect of gear 3, as the core, because there has been gear 3 could form engaged integral body.No matter gear 4 is done driving wheel, or gear 2 does driving wheel, because their the stressed ability balance in both sides of gear 3 has been arranged.Just even as the shaft strength that supports them, wearing and tearing are just little, otherwise bad just fast of whole power engine, putting off until some time later gear 3 also is the joint of an output torque, adapts to the equipment of those needs opposite direction moments, so that commutate.In addition, gear 3 also is that an output shaft can connect a flying wheel by speed reducer, is used to regulate the rotating speed of power machine output shaft and the stationarity of moment.
What is called is raised the efficiency, and requires the rotating speed of power machine output shaft to want high exactly, and it is big that moment is wanted.
At first to select the place of the condition that is fit to that ocean wave power machine is installed, as everybody knows, hydroelectric power plant will be built the place that drop is big, the water yield is abundant in, as a same reason, ocean wave power machine will select bigger sea of wave or seashore to build a station, it is not all right at will looking for a place to build sea wave generator station, and condition is weaker certainly, can realize with the way of artificial construction terrain and its features.
The float of suitable shape of its less important selection and size.Float is selected too big, general moderate seas can not lifted it again, that can not do again is too little, too little float buoyancy is big inadequately, decide, preferably select the elongated cylinder shape so require it to export great moment, make its 4/5 or 5/6 part sink under the water more stable as for shape according to power engine itself, can float over like this on the sea, can rise and fall with wave again and move.Shared space is also little, because a power engine will install several floats, also will design a framework when implementing in the future and only allow float to move up and down, and can not all around float.
In the situation of blank machine, have only a float to drive two rocking bars and two flywheels in addition, after a wave was gone over, the impulse action of having only two moments was to the input shaft of power engine, so the rotating speed of the output shaft of power engine is inhomogeneous, and moment is big inadequately.For this reason, we have thought a good method, and the enforcement of this way is that ocean wave power machine moves towards practical key.That is exactly the quantity that increases float.
In face of (or vertical) sea direction, equidistant placement float as much as possible before and after in the distance of half wavelength, just as the blank machine is connected with the power engine input shaft with flywheel with rocking bar, (but Fig. 2 only marks the situation of 5 floats) is if there be n float as shown in Figure 2, so after a wave is gone over, just there is n that (2n) moment pulse is continuously acted on the power engine input shaft, make the huge strength of its output shaft output, rotating speed also can be accelerated, and the energy of each wave is fully used.
Just have only the power engine of five floats below, let us is analyzed and researched, these five tracks that float moves in one-period, as shown in Figure 3.
Fig. 3 (1) expression is desirable calm situation.As Fig. 3 (2) expression float D
1At trough, D
5At crest, D
3On horizontal line, this has only D in a flash
2, D
4In work.When wave advances π/4 (45 °) left, just become the state of Fig. 3 (3), at this moment D
2On horizontal line, D
4On crest, has only D
1, D
3, D
5In work.When wave advanced 3/2 π (270 °) left, the track of five floats had just become the situation of Fig. 3 (4), at this moment except D
1, D
5On horizontal line, D
3At trough, has only D
2, D
4In work.When wave advanced 2 π left, when promptly carrying out one-period, their track had just become Fig. 3 (5), the situation striking resemblances of this situation and Fig. 3 (2), each float is got back to original position again, just illustrates that it is clocklike that float moves in wave, goes round and begins again.
From Fig. 3 (2) to (5) figure, as seen, moment at any time, three float moments on being in Wave crest and wave trough and horizontal line do not work, have at least 2 floats to work at the same time.If centre at five floats, install four floats again, altogether nine floats have just been arranged, so in any moment, have at least six floats to work at the same time, always have in other words six to the impulse action of (12) moment on two input shafts of power engine, so ocean wave power output energy need not be suspected.
Can utilize lever principle, increase the angular displacement of input, reach the efficient purpose that improves power engine.At first the rocking bar of power engine is all shortened and erect again, counterweight has originally just become weight, build a support again in the front of power engine, on support, erect long lever, with connecting rod the vertical lever that itself and power engine have shortened is linked up, the rocking bar of the new peace of level is one with the long vertical lever of new peace again, and its other end connects with the float strand, as shown in Figure 4, L wherein
1＞L
2, P is the counterweight of horizontal rocking bar.
When wave is big especially, above-mentioned way just dying even can cause the danger that the lever stretch bending is broken, so we find out a good method again, with lever L
1, L
2Replace with the sprocket wheel that differs in size respectively, connecting rod is replaced with chain, as shown in Figure 5, do like this can play fully and utilize lever principle to want the amplification that reaches.
In a word, our ocean wave power machine of invention is feasible, and it is simple in structure, can do very greatly, also can do very for a short time, and floor space is also little, and the abundant bay of Wave energy can install many simultaneously.Outlying fishing village, island can solve electrical problem, and unmanned island and submerged reef can solve the beacon lighting problem, and the Nansha and the Xisha Islands can solve electrical problem ... those archipelago countries are benefited maximum in the world.
