Embodiment

Below in conjunction with accompanying drawing, explain technological scheme of the present invention.

According to shown in Figure 4, two gatherers of the present invention are linked to each other by connecting rod, suppose at piston to be in the support arm neutral position, and the length between two gatherer central points are a half of wave wavelength, two gatherers that link to each other can produce significantly relative movement, absorb the energy of wave morely.When two continuous gatherers were in the trough both sides, because gravity and floating function, two gatherer main bodys were pushed to intermediate connecting rod, and connecting rod promotes piston rod and the inside cavity direction motion of piston.There is end ring connecting rod two ends and piston rod end, and connecting rod end ring and piston rod end ring interlock.Like this, when between continuous two gatherers relative movement being arranged, do not cause support arm to be subjected to very big lateral force, what piston carried out with respect to support arm is straight line motion.

As shown in Figure 1, when the inside cavity direction of piston moved, the valve of the liquid extruding liquid sucting port in the cavity of support arm upper strata was closed it; Simultaneously, the liquid extruding mouth spray valve in the cavity of support arm upper strata is opened it, and liquid impacts to impeller from mouth spray, makes wheel rotation, and impeller drives rotating shaft and rotates, and rotating shaft drive generator amature rotates and generates electricity.At this moment, liquid flows by arm end internal voids sap cavity on support arm in the support arm lower floor cavity, cavity internal pressure reduces in support arm lower floor, makes bottom mouth spray valve closing, bottom liquid sucting port valve open, and the liquid in the inner chamber flows into support arm lower floor cavity from the bottom liquid sucting port.In the identical time, the liquid that the top mouth spray is injected inner chamber approximates the liquid that flows into support arm lower floor cavity from the bottom liquid sucting port, and the total amount of liquid in inner chamber, support arm inside all remains unchanged at any time like this.

As shown in Figure 4, two gatherers that link to each other are when the both sides of crest, because gravity and buoyancy function make the gatherer main body to the pulling of connecting rod two ends, connecting rod pulling piston rod and piston are to the direction motion away from inner chamber.

As shown in Figure 1, piston is when moving away from interior cavity direction, liquid flows to support arm lower floor cavity by the arm end space in the cavity of support arm upper strata, fluid pressure reduces in the cavity of support arm upper strata, pulling top mouth spray valve closing, top liquid sucting port valve open, liquid flows to sap cavity on the support arm by the top liquid sucting port in the inner chamber.At this moment, liquid extruding bottom liquid sucting port valve is closed it in the support arm lower floor cavity; Simultaneously, liquid extruding bottom mouth spray valve is opened it in the support arm lower floor cavity, and liquid impacts to impeller from the bottom mouth spray, makes wheel rotation, and impeller drives rotating shaft and rotates, and rotating shaft drive generator amature rotates and generates electricity.No matter be the liquid of top mouth spray or bottom mouth spray ejection, all make impeller all the time towards a direction rotation.

Wave energy along with wave progresses to front transfer, but seawater does not advance with wave progresses, cause at no ocean current and other under situation of external force influence of seawater directional flow, the seawater particle closes shuttling movement (its track as shown in Figure 5) owing to receiving Wave energy.Link to each other two gatherers because the position difference in seawater, the direction and the speed of following corresponding seawater particle movement are different, will produce relative movement each other, connecting rod, piston rod become the straight line motion of piston in support arm to this relative movement, thereby make mouth spray ejection liquid drive generator for electricity generation.

According to shown in Figure 3, on top of the present invention gas compartment is arranged, be for gatherer can be floated on the surface.Gas compartment sees from above and is " ten " font that when shuttling movement was closed in the generation of seawater particle, this shape can make full use of its kinetic energy, makes the gatherer movement therewith, thereby makes two continuous gatherers produce relative movement owing to moving direction is different with speed.The gas compartment size makes gatherer buoyancy be slightly larger than gravity by the weight decision of gatherer, has only the sub-fraction of gas compartment to surface, and so just can effectively utilize the potential energy and the kinetic energy of wave.Two striking plates are " ten " font cross-like, and the kinetic energy in the time of more effectively utilizing the seawater particle movement like this promotes or spurs two gatherers that link to each other and produces relative movement, makes seawater kinetic energy be converted into electric energy.

Suppose that piston movement speed is V1, support arm upper strata cavity diameter and mouth spray diameter ratio are n, and atomizing of liquids speed is V2.The liquid that the unit time inner carrier promotes should equal the liquid that mouth spray ejects, therefore, V2=n * n * V1, the liquid velocity that promptly ejects be enlarged into piston movement speed n square doubly; The present invention has become the high-speed motion of atomizing of liquids to the low-speed motion of wave, though the atomizing of liquids quality is little in the unit time, because of the fast energy height of speed.The energy transfer of atomizing of liquids has been given generator, thereby makes generated output power also bigger.

As shown in Figure 1, the inside cavity direction of mouth spray valve can be opened, and can not open to the support arm direction, and it is when opening, and its inner wall smooth with a common inner wall smooth, the cylindrical circular mouth spray formed of mouth spray other parts, makes liquid can spray to inner chamber smoothly.Liquid sucting port valve back is " bow " shape, can only be semi-open state when it is opened, and like this, when liquid pushed the liquid sucting port valve in support arm, this valve was under pressure and can closes rapidly; The liquid sucting port valve can only be opened to the support arm direction, and inwardly cavity direction can only be closed.

Obtain bigger power, must have a plurality of gatherers to link to each other.Because wave wavelength, wave height and seawater particle movement speed, direction are uncertain, in order to make full use of Wave energy, can adopt chessboard of go shape to link between the gatherer, promptly at the gatherer of centre, its 4 support arms link with corresponding 4 support arms of 4 gatherers of 4 directions respectively.Like this, produce relative movement between gatherer and at least one gatherer that links to each other in the middle of the wave of any direction all can make, thereby make generator for electricity generation.A plurality of gatherers link like this, resemble the chessboard of go shape.

Because the irreqularity of wave motion, make the relative movement that links to each other between two gatherers sometimes fast and sometimes slow, make piston motion sometimes fast and sometimes slow, thereby the liquid velocity that ejects is sometimes fast and sometimes slow, the speed that promotes the impeller rotation also just changes, the generator amature rotating speed is also changed, finally cause output voltage to change.The scheme that solves the output voltage variation is as follows: generator adopts alternator, and generator output voltage is received in the transformer input; Measure this transformer output voltage, this voltage and established standards voltage are compared, obtain a difference signal, this signal is carried out power amplification, deliver to the control motor, motor direction, amplitude size as requested rotated, and the motor drives transformer rotates, and makes the transformer output voltage move closer to normal voltage; In transformer output voltage change procedure, difference signal also constantly changes, and motor also rotates thereupon, makes the transformer output voltage stabilization on the established standards magnitude of voltage.

Ordinary circumstance of the present invention is placed down in the seawater, and seawater is corrosive, so will consider the corrosion protection problem.The present invention is full closeding state, and inside does not directly contact with seawater, thus can or stick on this machine exterior with anti-corrosion materials such as plastics, rubber, corrosion prevention film parcel, with insulating sea water; Because the relative support arm of piston rod position can change, therefore can be with flexible or retractable anti-corrosion material at this position.

The present invention floats on the surface generally speaking, exposes the small part of gas chamber.Avoid surperficial ocean current, or use the anchor body, make gatherer be trapped in the original place basically, can only move among a small circle.Avoid diastrous weathers such as hurricane, before this, gatherer can be dragged to place of safety, or emit the gas compartment portion gas, make it sink to the seabed and avoid disaster, treat that disaster charges into gas later again and makes its come-up can continue to use.
