Description of drawings
Fig. 1 is a structure principle chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing principle of the present invention, structure are done further explanation.
As shown in Figure 1, wave energy generating set peculiar to vessel mainly is made up of pendulum manger board 1, gear drive, Hydraulic Power Transmission System, generator 17, fixed pedestal 2.The input end of Hydraulic Power Transmission System is an oil hydraulic cylinder, and the piston rod 10 of oil hydraulic cylinder connects with pendulum manger board 1 through gear drive, and hydraulic cylinder 9 connects with fixed pedestal 2.Oil inlet and outlet 21 fork in oil hydraulic cylinder fluid chamber 12 is divided into two-way, and one the tunnel connects high pressure accumulators 15 through fuel-displaced one-way valve 14, pressure duct 13, and another road connects intermediate-pressure accumulators 19 through return check valve 20, return line 18.Oil hydraulic cylinder rodless cavity 11 connects low-pressure chamber 6 through rodless cavity air outlet 8, tracheae 7.Hydraulic cylinder piston rod 10 stretch out a side and the fixed driving fit of oil hydraulic cylinder cover, thereby formed the cylinder exocoel 5 with the seawater seal, cylinder exocoel 5 connects with low-pressure chamber 6 through cylinder exocoel air outlet 4, tracheae 7, assists the free to-and-fro motion of realization piston rod 10.M is the sea level.
Wave energy to the process of electric energy conversion is: wave 23 from crest when trough moves; Drive 1 swing of pendulum manger board; The planet wheel 22 in gear drive and the engagement transmission of gearwheel 3; Pulling piston rod 10 moves downward; Because of hydraulic cylinder 9 connects and can't be pulled with fixed pedestal 2; Therefore piston rod 10 produces relative movement with hydraulic cylinder 9; Rodless cavity 11 volumes of oil hydraulic cylinder increase; The volume in fluid chamber 12 reduces; Fluid is extruded; Because one-way valve only allows fluid to flow toward a direction, the fluid of extruding is through fuel-displaced one-way valve 14; Pressure duct 13 gets into high pressure accumulator 15, thereby realizes the conversion of wave energy to the hydraulic pressure ability; Wave 23 from trough when crest moves; Piston rod 10 moves upward; Rodless cavity 11 volumes of oil hydraulic cylinder reduce; The volume in fluid chamber 12 increases; Hydraulic pressure reduces; When being lower than the hydraulic pressure of intermediate-pressure accumulator 19; Return check valve 20 is opened; The pressure in fluid chamber 12 just approaches the pressure of intermediate-pressure accumulator 19; And, just equal the pressure of low-pressure chamber 6, so the piston both sides for the pressure of rodless cavity 11; The hydraulic pressure in fluid chamber 12 is greater than rodless cavity 11 pressure, and the piston of oil hydraulic cylinder just relies under the pressure reduction of the middle pressure that acts on its both sides and low pressure and resets.In the whole conversion process of energy, the circulation route of hydraulic oil is fluid chamber 12, fuel-displaced one-way valve 14, pressure duct 13, high pressure accumulator 15, oil hydraulic motor 16, intermediate-pressure accumulator 19, return line 18, return check valve 20, fluid chamber 12.Intermediate-pressure accumulator 19 plays voltage stabilizing.In hydraulic system actuating station, oil hydraulic motor 16 can convert hydraulic pressure into mechanical energy, oil hydraulic motor 16 and generator 17 connecting shafts, and generator 17 converts mechanical energy into electric energy again, thereby has accomplished the overall process of whole wave energy to the electric energy conversion.
