In the embodiment of the present invention, each part of the structure may adopt various modes that can be easily considered by those skilled in the art, and for convenience of implementation, the following structural forms are preferably adopted:
As shown in fig. 2, the hinged rocker 2 may include the rocker 21 and a rocker base 23, and the bottom of the rocker 21 is fixedly connected with the hinged ball head 22; the rocker base 23 is internally provided with a built-in spherical cavity 24, and the built-in spherical cavity 24 realizes the limiting and hinged rotation of the hinged ball head 22 through a base upper limiting universal wheel 25 and a base lower limiting universal wheel 26 which are arranged on the upper circumference and the lower circumference. The articulation angle of the articulation rocker 2 is practically less than 90 ° limited by the mechanical movement.

In order to improve the buffer contact point and the contact area, the upper limit cover and the lower limit cover (i.e. the ball limit upper cover 31 and the ball limit lower cover 35) of the omnibearing movable ball head 3, the upper buffer pad 32 and the lower buffer pad 34 may be symmetrically arranged, and the outer shapes of the upper buffer pad 32 and the lower buffer pad 34 are arc-shaped.
As shown in fig. 4, the kinetic energy conduction embedded disc 4 may include an embedded disc limiting slip ring 41, an upper limiting universal wheel 42 and a lower limiting universal wheel 43 are fixed on the upper circumference and the lower circumference of the inner side of the embedded disc limiting slip ring 41 respectively, the upper limiting universal wheel 42 and the lower limiting universal wheel 43 are clamped on the ball body 33, the embedded disc limiting slip ring 41 is movably hinged with the omnibearing movable ball head 3, the kinetic energy conduction embedded disc 4 further includes an embedded disc body 44, and embedded disc limiting universal wheels 45 are symmetrically arranged on the upper and lower circumferences of the outer side of the embedded disc body 44.
In the embodiment of the invention, the upper disc 51 and the lower disc 53 of the driven double disc 5 keep synchronous movement under the fixing action of the connecting rod 52, and the linear columnar guide rail 6 further limits that the upper disc 51 can only longitudinally move, so that the linear conversion of energy is realized.
In addition, in the above embodiment, the movement of the hinged rocker 2 is further limited herein, including the movement range of the disc body 44 in the space of the upper disc 51 of the driven double disc 5 and the movement ranges of the upper and lower limit covers and the upper and lower buffer pads of the omnibearing movable ball 3.
The linear conversion from capturing kinetic energy to mechanical activity is a precondition for realizing piezoelectric power generation, and the embodiment of the invention realizes the function through the mutual coordination of structures such as the energy capturing blade 1, the hinged rocker 2, the omnibearing movable ball head 3, the kinetic energy conduction embedded disc 4, the driven double disc 5 and the like. The specific process is as follows: the energy harvesting blade 1 collects ocean energy in any direction, the hinged rocker 2 is pulled to rotate in any direction by taking the hinged ball head 22 as a circle center, the omnibearing movable ball head 3 is limited by the kinetic energy conduction embedded disc 4, so that the omnibearing movable ball head 3 also drives the kinetic energy conduction embedded disc 4 to move when swinging along with the hinged rocker 2, the kinetic energy conduction embedded disc 4 can translate in the upper disc 51 of the driven double disc 5, therefore, only longitudinal acting force is conducted to the upper disc 51, and the lower disc 53 and the linear columnar guide rail 6 finally achieve the action effect of longitudinal movement of the lower disc 53 in view of the action of the upper disc 51, the lower disc 53 and the linear columnar guide rail 6 of the driven double disc 5.
As shown in fig. 5-7, in some embodiments of the present invention, the piezoelectric-electromagnetic power generation and energy storage integrated module 7 may include an upper 6-group inner magnet 71, an outer magnet 72, a piezoelectric-electromagnetic power generation structure, a power transmission trace 74, a rectifying module 75, and the energy storage structure 76 at the bottom, where:
The inner magnets 71 and the outer magnets 72 of each group respectively represent magnetic south poles and magnetic north poles, a plurality of piezoelectric-electromagnetic power generation structures are arranged between the inner magnets 71 and the outer magnets 72, and the piezoelectric-electromagnetic power generation structures are connected through power transmission wires 74.
The piezoelectric-electromagnetic power generation structure can be built by adopting the prior art, in order to improve the power generation efficiency, preferably, the piezoelectric-electromagnetic power generation structure is a segmented tapping type piezoelectric-electromagnetic power generation structure 73, and comprises a conductor upper cover 731, a piezoelectric-magnetic induction spring 732, a first tapping structure 733, a second tapping structure 734, a third tapping structure 735, a piezoelectric lower guide piece 736, a piezoelectric power generation material 737 and a piezoelectric power generation material chassis 738, wherein the piezoelectric-magnetic induction spring 732, the first tapping structure 733, the second tapping structure 734 and the third tapping structure 735 are sequentially concentrically arranged from outside to inside.
Further, the upper conductor cover 731 and the lower piezoelectric guide piece 736 are made of conductive materials, a first extending circular ring 7311, a first tapping spring 7331, a second extending circular ring 7313, a second tapping spring 7341, a third tapping starting screw 7315 and a third tapping spring 7351 can be sequentially fixed below the upper conductor cover 731 from outside to inside, a first tapping starting screw 7312 is symmetrically connected below the first extending circular ring 7311, a second tapping starting screw 7314 is symmetrically connected below the second extending circular ring 7313, the upper part and the lower part of the piezoelectric-magnetic induction spring 732 can be respectively connected with the upper conductor cover 731 and the lower piezoelectric guide piece 736, the piezoelectric power generation material 737 is fixed below the lower piezoelectric guide piece 736, the piezoelectric power generation material chassis 738 is fixed below the piezoelectric power generation material 737, the lower guide piece 736 and the piezoelectric power generation material 737 are connected to the rectifying module 75 through the power transmission line 74, the inner magnet 71, the outer magnet 72, the rectifying material chassis and the energy storage module 75 are fixed above the rocker 76, and the middle structure is fixed above the rocker 76.
At this time, in order to adapt to the complexity of ocean energy, two power generation modes can be adopted:
first, when ocean energy is lower, the motion amplitude of the hinged rocker 2 is smaller, and at the moment, the downward motion amplitude of the lower disc 53 is also smaller, and a stable low-voltage piezoelectric-electromagnetic power generation mode is adopted, so that the power generation process is as follows:
When the lower disc 53 presses down the upper conductor cover 731, the upper conductor cover 731 displaces relative to the lower piezoelectric guide piece 736, the piezoelectric-magnetic induction spring 732 continuously compresses the lower piezoelectric guide piece 736, the lower piezoelectric guide piece 736 further compresses the piezoelectric power generation material 737, and the chassis 738 of the piezoelectric power generation material is mainly used for supporting the piezoelectric power generation material 737, so that stable stress of the piezoelectric power generation material 737 is ensured, and relatively stable low-voltage current is generated; during this time the piezo-magnetic induction spring 732 cuts the magnetic induction wire, also producing a relatively stable low voltage current.

The high voltage current generated by the segmented percussive piezoelectric-electromagnetic power generation structure 73 flows as follows: according to the difference of the pressing-down amplitude of the lower disc 53, three layers of taps are sequentially arranged, and the energy is gradually increased layer by layer.
First, the first layer tapping is performed by the first tapping structure 733: the lower disc 53 presses down the upper conductor cover 731, since the first tapping start screw 7312 extends down to the longest span, it first touches the first tapping trigger bearing 7338, and the first tapping trigger bearing 7338 and the first track bearing 7337 are coaxially fixed to the first tapping ring 7332 through the first external upright post 7336, and the first tapping ring 7332 is limited by the first peripheral limiting ring 7334 and can only rotate and move up and down, so that the first tapping ring 7332 leaves the upper part of the first tapping track 7335 under the action of the first external upright post 7336, and relatively violent tapping occurs downwards under the accumulated potential energy of the first tapping spring 7331 and the gravity of the first tapping ring 7337, so as to generate high-voltage current. In addition, the track reservation space 7333 reserves a movement space for the second layer tap.

Finally, the third layer tap is embodied by a third tap structure 735: the lower disc 53 further presses down the upper conductor cover 731, the third tapping trigger screw 7315 finally touches the third tapping trigger bearing 7357, the third tapping trigger bearing 7357 and the third track bearing 7356 are coaxially fixed on the third tapping circular ring 7352 through the third external upright post 7355, and the third tapping circular ring 7352 is limited by the third peripheral limiting circular ring 7353 and can only rotate and move up and down, so that the third tapping circular ring 7352 leaves the upper part of the third tapping track 7354 under the traction of the third external upright post 7355, and relatively violent tapping occurs downwards under the action of accumulated potential energy of the third tapping spring 7351 and self gravity, and high-voltage current is generated.
