Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be illustrated in figure 1 a kind of floating type sea wave generator automatically to wave, comprise the buoyancy tank 1 of sealing configuration, tubular linear motor, the steering gear 2, hawser 5, rotatingshaft 4 and rotary bearing 3.
Described cylindrical permanent linear synchronous motor comprises stator 6, mover 11, sliding axle 7, two sliding bearings 8, two springs 9 and two ring-type sandboxes 10; Described mover 11, two sandboxes 10, two springs 9 and two sliding bearings 8 are all set on sliding axle 7, wherein mover 11 is fixed on the middle part of sliding axle 7, two sandboxes 10 are weldingly fixed on the two ends of mover 11 respectively, two springs 9 lay respectively at the outside of two sandboxes 10, two sliding bearings 8 lay respectively at the outside of two springs 9, and the outer end of spring 9 is against on sliding bearing 8; The axis of described stator 6 is provided with cylindrical hole, and the outer ring of described two sliding bearings 8 is fixedly mounted on the two ends of cylindrical hole.
Described the steering gear 2 is fixedly mounted on the bottom of buoyancy tank 1; Described rotary bearing 3 is arranged on the bottom of the steering gear 2, and described rotatingshaft 4 is arranged on rotary bearing 3, and described hawser 5 is connected with rotatingshaft 4; Described hawser 5 is used for whole electricity generating device to tie up to suitable marine site.
As shown in Figure 2, described the steering gear 2 for cross section be the prism structure of quadrilateral, two catercorner lengths of described quadrilateral are unequal, and described quadrilateral respectively relative two diagonal symmetries, and namely the steering gear 2 can be divided into two triangular prism structures different in size; A diagonal longer in described two diagonal and the long axis of buoyancy tank 1 are fitted.
As shown in Figure 3, the permanent magnet 12 of cylindrical permanent linear synchronous motor is attached to mover 11 surface, and armature winding 13 is arranged in the groove of stator 6.
When there being the wave parallel with motor sliding axle 7 direction below buoyancy tank 1, due to the length relation of buoyancy tank 1, one end of buoyancy tank 1 is in crest, one end is in trough, the mover 11 of the inside is due to self Action of Gravity Field, drive sliding axle 7 to horizontally slip, thus produce relative movement with stator 6, just can generate electricity.
When wave direction and motor sliding axle 7 direction inconsistent time, the thrust that long that side of tri-prism of the steering gear 2 is subject to wave can be greater than that side of short tri-prism, thus drives whole buoyancy tank 1 to rotate, and make sliding axle 7 consistent with wave direction, realization is automatic to wave.
If electricity generating device working sea area wave is comparatively large, electric mover 11 quality can be increased by adding sand in sandbox 10, making buoyancy tank 1 have larger potential energy with mover during Wave oscillating 11, thus increase motor endergonic efficiency from wave.If electricity generating device working sea area wave is less, overweight mover 11 will make buoyancy tank 1 with Wave oscillating, now cannot can take out sand from sandbox 10, enable electricity generating device absorb energy from wave.
