When pendulum plate 2 swung, vertical slipper 23 because cross sliding clock 52 is hinged with vertical slipper 23, carried out horizontal sliding in the horizontal concrete chute 51 of cross sliding clock 52 on support 5 along the vertical chute 22 interior relative slidings of putting on the plate 2.When pendulum plate 2 swings with certain speed, make the spring 24 that holds mutually with impact head 25 compressed.Simultaneously, pendulum plate 2 can begin to-and-fro motion for gyration center take its swing plate shaft 21, guarantees that pendulum plate 2 can not surpass its stroke range, make to put plate 2 and can effectively work.
As shown in Figure 1, described mechanical transmission mechanism 3 comprise Timing Belt 31, the overrunning clutch of two synchronous pulleys 32, two crankshaft-link rods 33, a bent axle 34, two tooth bars and two rotating in same directions that link to each other by Timing Belt 31.
A described wherein synchronous belt wheel 32 is installed on the swing plate shaft 21, and another synchronous pulley 32 is installed on the bent axle 34.One end of described two crankshaft-link rods 33 all is installed on the bent axle 34, bent axle 34 and two crankshaft-link rod 33 joints are crankshaft journal A and crankshaft journal B, both are 180 degree angles, the other end of described two crankshaft-link rods 33 links to each other with two tooth bars respectively, the overrunning clutch 7A that one of them tooth bar 6A is mated is meshed, the overrunning clutch 7B that another tooth bar 6B is mated is meshed, described overrunning clutch 7A is connected connection with overrunning clutch 7B, and link to each other with motor shaft by coupling 8, described tooth bar 6A and tooth bar 6B all are installed on the base 1.
Described base 1 is provided with two tooth bar chutes 11, and described two tooth bar 6A and 6B are installed in respectively in two tooth bar chutes 11, and tooth bar 6A and tooth bar 6B can be limited in orbit.
Described base 1 is provided with bearing 12, and described bent axle 34 is installed on the bearing 12, and bent axle 34 can be rotated smoothly.
When pendulum plate 2 swings in wave, driving the synchronous pulley 32 that links to each other with swing axis 21 through swing axis 21 rotates, transmission by Timing Belt 31, driving the synchronous pulley 32 that links to each other with bent axle 34 rotates again, and then bent axle 34 is rotated, because two crankshaft-link rods 33 are 180 degree angles with crankshaft journal A and the crankshaft journal B of bent axle 34 joints, tooth bar 6A and tooth bar 6B that two crankshaft-link rods 34 are driven make reverse iso-variable velocity straight line motion.The periodic reciprocating of pendulum plate 2 is output as unidirectional straight line motion.
As shown in Figure 4, described overrunning clutch 7A and overrunning clutch 7B include outer yoke 71, star-wheel 72, roller 73, spring 74, fore-set 75 and rotating shaft 76.
Described outer yoke 71 peripheries are meshed with tooth bar, and place the outside of star-wheel 72, described star-wheel 72 outsides are the chisel teeth structure, and the length of the bi-side of chisel teeth is different, be divided into long side surface 77 and short side 78, described roller 73 is arranged between the chisel teeth of star-wheel 72, and match with outer yoke 71, described roller 73 holds mutually by fore-set 75 and spring 74, one end of described spring 74 is installed on the short side 78 of star-wheel chisel teeth, one end of spring 74 can be installed in the groove of short side 78, also can be installed in the end face of short side 78.Described star-wheel 72 links to each other with coupling 8 by its rotating shaft 76, and described base 1 is provided with bearing 13, and described rotating shaft 76 is installed on the bearing 13, thereby rotating shaft 76 can be rotated smoothly.
Roller 73 in the described overrunning clutch contacts with star-wheel 72 with outer yoke 71 under the spring-force driven dual of spring 74 all the time.When outer yoke 71 counterclockwise active rotation, or during star-wheel 72 clockwise active rotation, overrunning clutch all enters wedging state, i.e. working state; Otherwise overrunning clutch is disengaged condition.Can only the single direction transmission when power source drives passive device, if when power source turns, as becoming clockwise counterclockwise, passive device then can automatic trip from the function that does not produce any power and transmit.The roller 73 of overrunning clutch can freely rotate in raceway, still can keep circular after the wearing and tearing, and the point of contact of roller 73 and star-wheel 72 and outer yoke 71 is not identical when separating in wedging, even wearing; When overload, roller 73 slides, and overrunning clutch can not be damaged, and clutch still can be locked, and recovers normal working.Certainly, the sense of rotation of overrunning clutch working state also can be outer yoke 71 clockwise active rotation, as long as change the installation direction of chisel teeth.
As shown in Figure 1,33 band carry-over bar 6A move right from figure when crankshaft-link rod, the gear of the outer yoke of overrunning clutch 7A just can be driven does clockwise rotation, this moment, overrunning clutch 7A idle running was not worked, crankshaft journal B band carry-over bar 6B is to left movement simultaneously, the gear of the outer yoke of overrunning clutch 7B just can be driven does counterclockwise rotation, and overrunning clutch 7B work this moment drives rotating shaft 76 and rotates, thereby motor shaft is rotated so that the generator generating by coupling; With should tooth bar 6A in the drawings to left movement, when tooth bar 6B moves right, this moment, overrunning clutch 7B idle running was not worked, overrunning clutch 7A work drives rotating shaft 76 and rotates so that generator generates electricity, the direction that rotating shaft 76 is rotated is the same with the first situation, no matter the direction when tooth bar is reciprocating so how, the corresponding outer yoke of rack drives is done periodic motion, make a job in two coaxial overrunning clutchs in the same way, linear reciprocating motion is converted into rotatablely moving that output terminal is identical, sense of rotation is identical.Utilize overrunning clutch can only one the direction characteristic of rotating, mechanical transmission mechanism 3 has absorbed the all-wave wave and has acted on wave force on the pendulum plate 2, so conversion efficiency is doubled theoretically, can realize full wave absorption.By overrunning clutch output one-way rotation, link to each other with generator 4, can guarantee normal power generation.
The electricity that described generator 4 sends converts Ac to direct current through rectified three-phase circuit first, charges a battery through behind the dc voltage regulation again, and the Ac that namely motor 4 is sent becomes direct current and stores in the storage battery.Can more effectively utilize wave energy and steady pressure like this, also can be converted into Ac to direct current for the user through the DC/DC variator again.The Main Function of DC/DC variator is for the load of regulating the dump load loop, thereby realizes the adjusting control to system's output power and accumulator cell charging and discharging.The unnecessary electric energy of generator output is responsible for consumption by dump load, thereby keeps the balance of system capacity, the generator set in the protection wave energy apparatus.
Every technical solutions of the utility model content that do not break away from, all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present utility model.
