The present invention concrete operating principle be:
When vibration bar assembly 1 is influenceed to move by ocean current, primary vibration bar 11 occurs simultaneously with secondary vibration bar 12 Irregular movement, because pull rope 111 is connected to secondary vibration bar 12 and straight-tooth by drive sleeve 19 and pulley assembly 21 respectively Bar 28, so spur rack 28 will also move up and down, and because spur rack 28 is meshed with ratchet 212, ratchet 212 and one-level Gear 29 matches, and one-stage gear 29 is engaged in the little gear 220 of secondary gear 218, gearratio 1:4, secondary gear 218 it is big Gear 218 is engaged in tertiary gear 221, gearratio 1:4, so the motion of spur rack 28 is converted under the drive of gears at different levels For directional rotating, it is driven always than 1:16;And in transmission case 25, bar permanent magnet 41 is coaxial with tertiary gear 221, therefore strip is forever Directional rotating also will constantly occur for magnet 41 so as to which cutting magnetic induction line is generated electricity.
In above process, spur rack 28, which moves up and down, will make ratchet 212 produce clockwise and two rotation sides counterclockwise To, therefore when spur rack 28 moves downward i.e. 212 rotate counterclockwise of ratchet, one side of ratchet 215 will first with one-stage gear 29 Groove lagging edge 210 at boss contacts and occurs relative motion, when ratchet 215 is moved at the outer terminal vertex of groove lagging edge 210 When will be pushed up back in pawl slot 213, now main spring 216 provide restoring force effect under ratchet 215 further occur it is suitable To moving and then contacting and relatively rotate with the groove lagging edge 210 at the next place of one-stage gear 29, thus constantly repeat to occur Above-mentioned motion process, each ratchet motion state is provided with same period rule, therefore in whole motion process, ratchet 212 is inverse To rotation and the remains stationary of one-stage gear 29, so the secondary gear 218 in transmission case does not also occur with tertiary gear 221 Rotational motion;Conversely, when ratchet 212 turns clockwise, ratchet 215 is then led with the groove at the boss of one-stage gear 2 first Side 211 contacts and occurs relative motion, when ratchet 215 is moved in groove guide margin 211 at terminal vertex at i.e. groove inner vertex When, groove lagging edge 210 is just in contact with ratchet 215 simultaneously, and ratchet 215 is then fastened in the recessed of one-stage gear 29 completely at this moment At groove, because ratchet 212 proceeds to rotate clockwise, therefore ratchet 212 will drive one-stage gear 29 that directional rotating occurs together, Again because one-stage gear 29, secondary gear 218 and tertiary gear 221 are intermeshed, the transmission for thus just completing transmission case 25 is made With the final bar permanent magnet 41 driven in power generation box 43, which is rotated, to be generated electricity.
Described above is only the preferred embodiment of the present invention, it should be pointed out that:For the ordinary skill people of the art For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should It is considered as protection scope of the present invention.
