Embodiment
Embodiment, with reference to accompanying drawing, a kind of boa formula wave-type electric generator, comprises that three above floating drums of floating drum 1, floating drum 22 and floating drum 3 30 form a floating drum string, each floating drum termination is fixed with otic placode 3 31, between two otic placodes 3 31, with bearing pin 2 29, is hinged; Oil hydraulic motor 24, generator 25, storage battery 27 and inverter 28 are all housed in each floating drum; Generator 25 is connected with oil hydraulic motor 24, and connects with charger 26, storage battery 27 and inverter 28; It is characterized in that with piston rod 5, being flexibly connected between every two floating drums, piston rod 5 is contained in cylinder tube 3 actively, the little axle of cylinder tube 3 use is contained on otic placode 1, and otic placode 1 is fixed on floating drum 1, and the otic placode 27 use bearing pins 26 of piston rod 5 one end and fixedly floating drum 22 terminations are hinged; In each floating drum, right-hand member is equipped with accumulator 18, and accumulator 18 use oil pipes 1 and oil pipe 2 13 are communicated with the chamber, left and right of cylinder tube 3 by one-way valve 1, one-way valve 2 15, one-way valve 3 16 and one-way valve 4 17; Accumulator 18 is equipped with pressure transducer 8 above, and pressure transducer 8 use signaling lines 9 are connected with controller 10; Controller 10 use electric wires 11 are connected with solenoid directional control valve 22; Solenoid directional control valve 22 use oil pipes 4 23 are communicated with oil hydraulic motor 24, with oil pipe 3 19, are communicated with relief valve 20 and accumulator 18; Solenoid directional control valve 22 is also communicated with fuel tank 21.Its work electricity generating principle is: floating drum string is under the effect of wave motion, and floating drum crossview boa is the same take bearing pin 2 29 as the reciprocal folding movement of axle, stretches or compression piston bar 5 to-and-fro motion in cylinder tube; When the relative cylinder tube 3 of piston rod 5 stretches, the left side oil pocket negative pressure of oil cylinder, the reverse not conducting of one-way valve 2 15, one-way valve 4 17 not conductings of high back voltage, only have one-way valve one 14 forward conductions, the hydraulic oil in fuel tank 21 is inhaled into the left side oil pocket of oil cylinder by oil pipe 13; Meanwhile, the right side oil pocket malleation of oil cylinder, one-way valve 3 16 forward conductions, the reverse not conducting of one-way valve 4 17, the hydraulic oil in the oil pocket of oil cylinder right side is pressed into accumulator 18 by one-way valve 3 16 and oil pipe 12.When relative cylinder tube 3 compression of piston rod 5, the right side oil pocket negative pressure of oil cylinder, the reverse not conducting of one-way valve 3 16, one-way valve one 14 not conductings of high back voltage, only have one-way valve 4 17 forward conductions, the hydraulic oil in fuel tank 21 is inhaled into the right side oil pocket of oil cylinder by oil pipe 13;
