As shown in Figure 1, can charger and storage battery 21 be installed at floating drum 1 internal fixation as required.
Shown in accompanying drawing 1 to 8, constitute most preferred embodiment of the present invention by said structure.
The working principle of above-mentioned most preferred embodiment is: the floating drum 1 that swims in the seawater waves with waves of seawater, thereby the rolling element 8 in the floating drum 1 is rolled back and forth in passage 24, promote connecting rod 3 and come back rotation around lower velocity shaft 6, when floating drum 1 waves to any direction, there is the rolling element 8 of half to make roll forward approximately, the connecting rod 3 that promotes this half cycle is made forward rotation, and remaining rolling element 8 is made negative sense and rolled, and promotes this half cycle connecting rod 3 and does the negative sense rotation.Because the ratchet 10 of connecting rod 3 and ratchet 7 positive negative senses engagement cross-distribution, to do to have in the connecting rod 3 of forward rotation the ratchet 10 of half positive engagement to drive lower velocity shafts 6 and make forward rotation, the ratchet 10 relative ratchets 7 that all the other negative senses mesh skid.Ratchet 10 drive shell of doing to have the half negative sense to mesh in the connecting rod 3 of negative sense engagement 14 are done the negative sense rotation, the ratchet 10 relative ratchets 7 of all the other positive engagement skid, float ceaselessly to change and wave direction, rolling element ceaselessly changes rotating direction, but see on the whole, half rolling element 8 is made roll forward, and it is roughly constant that all the other make the situation of negative sense rolling.Thereby for single-pawl, change along with connecting rod 3 sense of rotation, do intermittently engagement with ratchet 7, but see on the whole, the positive engagement that accounts for ratchet 10 total numbers 1/4th drives lower velocity shaft 6 and makes forward rotation, and it is roughly constant that the negative sense engagement drive shell 14 that accounts for ratchet total number 1/4th is simultaneously made the situation that negative sense rotates.The rotation that lower velocity shaft 6 and housing 14 are simultaneously, direction is opposite drives high speed shaft 8 and makes forward rotation continuously.Because connecting rod 3 sums are no less than four, thereby the ratchet that whenever meshes, ratchet be no less than two, and high speed shaft 18 is made continuously forward rotation more reposefully.The rotation of high speed shaft 18 drives generator for electricity generation through automatic speed changer for machine.When wave during with various condition size variation, because automatic speed changer for machine automatic speed changing guarantees that generator rotates generating in the nominal operation speed range.Abominable especially when weather, wave is huge and when surpassing the maximum functional rotating speed that generator allows, generator quits work automatically.The electricity that generator sends is electricity supply and use equipment directly, also can ashore send electricity or be stored in storage battery by power transmission cable and power to consumer when quitting work for generator.
According to working principle of the present invention, obviously any mechanical transmission that can do the speedup transmission can be used as transmission device of the present invention, the energy of the device of drive shell and lower velocity shaft because of utilizing the rolling element positive and negative direction to roll simultaneously simultaneously obtains bigger speedup multiple and by preferential elder generation usefulness.When adopting the conventional machinery speed increaser because housing can not rotate, all ratchets should with the equidirectional engagement of low speed dog end, contact points is distributed on around the lower velocity shaft.
The present invention can be used on the navigation mark light, also can be installed on the ships, and except still can generating electricity, also the ships that wave energy can be caused waves energy consumption, alleviates waving of ships by consumed energy like this.
