Below in conjunction with drawings and the specific embodiments, the present invention is described in further details.
Embodiment
Consult shown in Fig. 1, the wave-type electric generator of the two buoyancy aids of balanced type under water that generating efficiency of the present invention is high is mainly that the two buoyancy aids that are equinoctial point by a submarine platform 9, intelligence commutation parameter case 11, one generators 12 and a pair of main shaft of take intelligence commutation parameter case constitute.
Described submarine platform 9 is anchored on seabed by one group of anchor chain 10 or hawser, preferably: after adopting 3 point types and be merged into one with anchor chain 10, submarine platform 9 is anchored on to seabed.
Described gearbox 12 is placed on submarine platform, is provided with break-in and overrunning clutch mechanism in this gearbox, and it can, by existing techniques in realizing, not repeat herein; Be set with the first rope sheave 8 and the second rope sheave 6 on one side of the main shaft 7 of this gearbox, the output terminal of parameter case is connected to generator 12, and this main shaft is to provide power and intelligent break-in to wave-activated generator 12.
Two buoyancy aids of described a pair of balanced type comprise one group of surface floating body 1 and one group of underwater buoyant body 3, and surface floating body 1 is bubbled through the water column, and 3 of underwater buoyant body are immersed in the sea and fully in hydrostatic-layer.
Also can the first rope sheave 8 and the second rope sheave 6 common above install a guide plate 5, in the present embodiment, an end of guide plate can directly be fixed on gearbox 12, offer a pair of pilot hole 51 on it, for guiding the hawser of two tractive surface floating bodies 1 and underwater buoyant body 3.Separately have better scheme to be: also can offer positioning hole 31 on buoyancy aid under water, the hawser 2 of tractive surface floating body is wrapped on the first rope sheave 8 through this positioning hole 31 after the pilot hole 51 on guide plate again simultaneously.
Two buoyancy aids of described balanced type refer to surface floating body 1 and underwater buoyant body 3 when moment arbitrarily all in transient equiliblium or equipoise.Surface floating body 1 is on the water surface, and its function is to capture wave energy; The hydrostatic-layer of underwater buoyant body in not affected by wave energy, its function has been balanced action, and the water displacement of surface floating body 1 is exactly the constant buoyancy had in hydrostatic-layer underwater buoyant body 3, and upwards underwater buoyant body is downward for surface floating body, otherwise or, keep moving direction contrary; One motionless, and another is also motionless.
Can realize the present invention's two-way work doing generating of the wave-type electric generator of the two buoyancy aids of balanced type under water by two buoyancy aids of a pair of balanced type with the frequency alternation of wave.
Specific works flow process of the present invention is: surface floating body 1 is moved upward by the promotion of wave energy, drive driving shaft 7 actings through hawser 2 and the first rope sheave 6, underwater buoyant body 3 be subject to hawser 4 tractive and when doing work under the effect of wave energy with surface floating body, driving shaft 7 rotates, driving the second rope sheave 6 rotates, that is: being wound around hawser 4 moves downward underwater buoyant body 3, when surface floating body 1 reaches ripple when protruding, wave energy disappears, be subject to the quality of surface floating body self and the effect of underwater buoyant body 3 buoyancy, now surface floating body 1 is descending, underwater buoyant body is up, same driving shaft 7 opposite directions that drive rotate and do work, when wave reaches ripple when recessed, repeated work again, because wave is undying, so continuous doing work that this wave-type electric generator can go round and begin again, the high efficiency wave energy of capturing of energy, and especially can design intelligence commutation by parameter case 11() provide stable power to generator 12, realization utilizes the purpose of wave-energy power generation.
