1st, independent wave-activated power generation

When sea situation preferably, system acquisition wave energy substantially meets loading demand, compressed-air energy storage and flow of water accumulation of energy not work Make, the capture energy of butterfly both wings 2 drives mover 26 to generate electricity, complete wave energy and electric energy conversion.

In this case, piston 11 is moved under crank-bar linkage (Fig. 2) driving, and low pressure valve 10 is opened, high pressure valve 13 is closed, Realize that closed chamber 12 is consistent with atmospheric pressure, piston 11 is moved without vapour lock；The adhesive of electromagnetic clutch 30, the capture energy of both wings 2 Through reversing shaft 31 and the coupling driving mover 7 of crank-bar linkage 5, now system acquisition energy substantially meets load needs.Both wings pitching Commutated through no-load voltage ratio raising speed and axis, moved on high-speed driving mover 7, cutting magnetic line generates electricity, and when reaching the pitching upper limit, both wings are in song Under the effect of handle kinetic energy, quick lower suppression changes capture movement state, by reversing shaft 31 and crank transmission, drives piston 11 and mover 7 move down, and complete pitching periodic process.Generator loading torque is now can adjust, promotes both wings pitching frequency approaches wave frequencies, Realize the maximum capture of wave.

2nd, wave compression generates electricity

When sea situation is preferable, also there is surplus power in the wave energy of system acquisition, can drive piston 11 in addition to load is met Compressed air is stored to pressure air accumulator 14, to supplement difference power when energy is not enough.In this case, both wings 2 are needed and crank Joining beam 7 is coupled, while the coordinated regulation valve opening of 13 low pressure 10 high and closing, realize being moved on piston 11 air-breathing, move down compression with And air pressure controlling, wherein, it is under both wings capture mechanical energy effect, to realize that mover 7 generates electricity and piston 11 is low that air-breathing is moved on piston Pressure air-breathing dual-use function；It is that can be used to drive mover to generate electricity by both wings capture to move down compression, excess energy compression storage high pressure gas Body, when piston 11 is moved down, air accumulator air pressure is pressed in regulation and control to pressure storage regulation and control link emphasis, it is ensured that compressed energy-storage efficiency.

Now under state, in addition to the cutting magnetic line of high-speed driving mover 7 generates electricity, Collaborative Control height pressure valve and pressure storage are adjusted Control link, unnecessary wave energy is stored with compressed air and flow of water accumulation of energy form.On piston during 11 shifting, electromagnetic clutch 30 Reversing shaft 31 is coupled with crank-bar linkage 5, both wings pitching drives and moved on piston and mover, and cutting magnetic line generates electricity, meanwhile, low pressure Valve is opened, high pressure valve is closed, compression chamber's suction low-pressure gas, until reaching chamber roof, is moved on piston and terminated；And then mover Quick to fall after rise under both wings pitching and the kinetic energy double action of crank-bar linkage 5, cutting magnetic line generates electricity, while low pressure valve 10 is closed, High pressure valve 13 is open-minded, and gas to chamber falls after rise with piston and is compressed to pressure air accumulator, until reach chamber bottom, high pressure valve 13 closes, Low pressure valve 10 is open-minded.And then under both wings capture energy effect, drive reset is moved on piston 11 again, carry out next loop cycle Work.The air pressure of compression gas tank 14 reaches p_maxWhen, the compressor 16 of compression gas-pressure regulation and control link starts, and is pressed to flow of water gas-accumulating tank 18 Contracting air.Can regulate and control compressed energy-storage power change both wings and bow via suction gas volume is moved on adjustment piston 11 under this state Frequency is faced upward, realizes that highest wave can be captured.

3rd, wave expansion power generation

When sea situation is poor, system acquisition wave energy cannot meet power needed for load, and difference power need to be stored up by compressed air Can jointly be completed with flow of water accumulation of energy.In this case, both wings 2 need to be with the mechanical couplings of crank-bar linkage 5, while coordinated regulation high 13 is low 10 pressure valves are opened and closed, and realize shifting in the expansion of piston 11, the without hindrance falling of piston and pressure storage air pressure controlling, wherein, piston 11 During upper shifting, the wave energy and expansion energy mechanical couplings of both wings capture are common to drive mover 7 to generate electricity, while regulating and controlling pressure air accumulator 14 Air pressure, it is ensured that expansion efficiency；Piston 11 falls after rise, is quickly fallen after rise under mover 7 presses down under both wings and crank kinetic energy is acted on, and cuts magnetic The line of force generates electricity.
