Moving displacement is substantially zeroed, and therefore float 3 produces the heave movement of alternation under the effect of wave force so that tension force cable 4 stress
Checker occurs, and the stress of tension force cable 4 acts on movable pulley 8 so that heave hydraulic cylinder 10 piston cylinder moves back and forth.
When tension force cable 4 stress increases, movable pulley 8 moving, heave hydraulic cylinder 10 rodless cavity oil liquid pressure increases, and rod chamber sucks
Hydraulic oil in low pressure accumulator 26；When tension force cable 4 stress reduces, in the effect that energy storage accumulator 11 and movable pulley 8 are conducted oneself with dignity
Under, heave hydraulic cylinder 10 piston moves to rod chamber, it is achieved the lifting of hydraulic fluid pressure, has captured the kinetic energy of heave movement.
Caput Anas domestica pendulum 2 is connected with float 3 body and oscillating motor 1 by the way of hinged, under wave action Caput Anas domestica pendulum 2 generation
Oscillating motion, same driving oscillating motor 1 pumps hydraulic oil, it is achieved the capture of energy.
Being illustrated in figure 2 adjustment Caput Anas domestica and put the slideway slide block structure of 2 Areas of Water Plan, its Main Function is to drive screw mandrel by motor
14 movements realizing slide block 13, slide block 13 is guided by slideway 12, slide block 13 by the way of hinged with oscillating motor 1
Connect.Realize Caput Anas domestica by the adjustment of slide block 13 position and put the change of 2 damping of oscillations, to adapt to changeable sea situation, improve prisoner
Obtain width ratio.
It is illustrated in figure 3 the hydraulic circuit diagram of fluid pressure type energy output system, oscillating motor 1 and heave hydraulic cylinder 10 to export
Pulse hydraulic oil after high pressure accumulator 17 is stable, flow to hydraulic motor 19, stable input pressure ensure that electromotor
20 higher efficiency and stable output frequency.Rectifying valve group 15 is made up of four check valves 16, it is ensured that hydraulic cylinder absorbs oil
Liquid comes from low pressure accumulator 26, and the high-voltage oil liquid of discharge enters high pressure accumulator 17.Feed circuit 24 is played to low tension loop
The effect of repairing, on the one hand compensates the leakage of this closed type hydraulic system, on the other hand prevents low tension loop hypotony from causing liquid
Pressure system vibration, creep, noise and cavitation corrosion.
Device of the present utility model can be applicable to the electric energy supply of marine water surface observation buoy and underwater observation network node, but does not limits
