Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
Refer to shown in Fig. 1 and Fig. 2, wave energy generating set of the present invention comprises generator 1, buoyancy aid 2, frame 3, pendulum 4 and transmission device.Described buoyancy aid 2 is connected with frame 3, described buoyancy aid 2 is connected with bearing 6 by coupling shaft 5 with between frame 3, the lower end of described coupling shaft 5 is fixed on the middle part of the upper end of described buoyancy aid 2, described bearing 6 is arranged on the middle part of the upper end of described buoyancy aid 2, the lower end of described coupling shaft 5 is a tight fit in the inner ring of described bearing 6, and the middle part of described coupling shaft 5 is provided with the shaft shoulder 5.1 for frames 3; The upper end of described coupling shaft 5 is fixed on the middle part of the lower end of described frame 3.The described shaft shoulder 5.1 makes frame can flexible rotating relative to buoyancy aid 2.Described pendulum 4 and transmission device are all located in described frame 3.
Described transmission device comprises main drive gear 7, helper drive gear 8, first unilateral bearing gear 9 and the second unilateral bearing gear 10.Described main drive gear 7 is rotatably connected in described frame 3 by main shaft assembly 11; Described pendulum 4 is fixed on described main drive gear 7, in this specific embodiment, described pendulum 4 be semicircle and planar section upward, described pendulum 4 has two, the both sides of described main drive gear 7 are located at respectively by these two pendulums 4, and described pendulum 4 is bolted on described main drive gear 7.
Described helper drive gear 8 is rotatably connected on helper drive gear 8 in described frame 3 and described by auxiliary axis body assembly 8 and engages with described main drive gear 7.The moving direction that the first described unilateral bearing gear 9 and the second unilateral bearing gear 10 are rotatably connected on the moving direction of the first unilateral bearing gear 9 inner ring in described frame 3 and described and the second unilateral bearing gear 10 inner ring by Power output shaft assembly 13 is identical.The working principle of so-called unilateral bearing gear is, when the outer ring of unilateral bearing gear rotates towards useful direction, the inner ring of described unilateral bearing gear also can rotate, and when the outer ring of unilateral bearing gear rotates towards invalid direction, the inner ring of described unilateral bearing gear is just thrown off with outer ring.The first described unilateral bearing gear 9 engages with main drive gear 7, and the second described unilateral bearing gear 10 engages with helper drive gear 8, and described pto＝power take-off 13 is connected with generator 1.
Described buoyancy aid 2 be hemisphere and planar section upward.The left and right sides of described buoyancy aid 2 is equipped with for stopping the baffle plate 14 that frame 3 is rotated.The upper plane of described buoyancy aid 2 is a circular flat in fact, and the line between the center line of the surface of contact of two pieces of described baffle plates 14 and the upper plane of described buoyancy aid 2 is by the upper plane center of circle.
In this specific embodiment, described main drive gear 7 is 90 teeth, and helper drive gear 8 is 30 teeth, and the first described unilateral bearing gear 9 and the second unilateral bearing gear 10 are 15 teeth.
The working principle of this wave energy generating set is as follows:
Wave drives wave energy generating set motion, pendulum 4 swings under the drive of wave, and owing to being connected by bearing 6 between buoyancy aid 2 with coupling shaft 5, therefore frame 3 can freely be rotated relative to buoyancy aid 2, but by the effect of block 14 on buoyancy aid 2, relatively between frame 3 with buoyancy aid 2 rotate 180 °.Main drive gear 7 is driven when pendulum 4 swings, when making main drive gear 7 drive the first unilateral bearing gear 9 to rotate toward useful direction (even if rotatable direction of inner ring of the first unilateral bearing gear), the inner ring of the first described unilateral bearing gear 9 will drive pto＝power take-off to rotate, and now under the effect of helper drive gear 8, the sense of rotation of the second unilateral bearing gear 10 and the direction of rotation of the first unilateral bearing gear 9, the inner ring of the second unilateral bearing gear 10 is thrown off, therefore inoperative to pto＝power take-off.On the contrary, when main drive gear 7 drives the first unilateral bearing gear 9 to rotate toward invalid direction, now, the second one-way shaft gear 10 can drive pto＝power take-off to rotate, and the first unilateral bearing gear 9 pairs of pto＝power take-offs are inoperative.By with upper type, no matter pendulum whichaway swings (namely towards a left side still towards the right side) and all can make electrical power generators.
