Description of drawings
Fig. 1 is structure principle chart of the present invention.
Embodiment
Below in conjunction with accompanying drawing, principle of the present invention, structure are described further.
As shown in Figure 1, marine wave-energy power generating mainly is comprised 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 oil hydraulic cylinder, and the piston rod 10 of oil hydraulic cylinder connects with pendulum manger board 1 by gear drive, and hydraulic cylinder 9 connects with fixed pedestal 2.Oil inlet and outlet 21 forks in oil hydraulic cylinder fluid chamber 12 are divided into two-way, and one the tunnel connects high pressure accumulator 15 through oil outlet one-way valve 14, pressure duct 13, and another road connects intermediate-pressure accumulator 19 through return check valve 20, return line 18.Oil hydraulic cylinder rodless cavity 11 connects low-pressure chamber 6 by 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 isolation, cylinder exocoel 5 connects with low-pressure chamber 6 by cylinder exocoel air outlet 4, tracheae 7, assists the free to-and-fro motion that realizes piston rod 10.M is the sea level.
wave energy to the process of electric energy conversion is: when wave 23 moves from crest to trough, driving pendulum manger board 1 swings, planet wheel 22 in gear drive and the engagement transmission of gearwheel 3, pull piston rod 10 to move downward, because 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, so the fluid of extruding is through oil outlet one-way valve 14, pressure duct 13 enters high pressure accumulator 15, thereby realize that wave energy is to the conversion of hydraulic energy, when wave 23 moves from trough to crest, 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 lower than the hydraulic pressure of intermediate-pressure accumulator 19, return check valve 20 is opened, the pressure in fluid chamber 12 is just close to the pressure of intermediate-pressure accumulator 19, and for the pressure of rodless cavity 11, just equal the pressure of low-pressure chamber 6, so piston both sides, 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 whole conversion process of energy, the circulation route of hydraulic oil is fluid chamber 12, oil outlet 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 is converted to mechanical energy with hydraulic energy, oil hydraulic motor 16 and generator 17 connecting shafts, and generator 17 is converted to electric energy with mechanical energy again, thereby has completed whole wave energy to the overall process of electric energy conversion.
Described marine wave-energy power generating is arranged on the middle part of hull bottom by fixed pedestal 2.When ship navigated by water, the boat-carrying control system was opened the sealing hatch door automatically, with the marine wave-energy power generating automatic drawing back, and closed the sealing hatch door, stopped wave energy collection and generating; When ship berthed, the boat-carrying control system was opened the sealing hatch door automatically, opens marine wave-energy power generating, beginning wave energy collection and generating.
The electric power that described wave energy generating set produces directly is supplied in the unmanned environmental monitoring ship in ocean, realize that the unmanned environmental monitoring ship in ocean need not to configure diesel engine, directly provide power by the boat-carrying wave energy generating set, and the quality of power supply of output is stable, electromagnetic compatibility is good, and ship-borne equipment is worked under the ocean environment of complexity.
