Wherein, the upper part of the fixed cylinder 1 is a circular tube 12, and the lower part is a cylinder 13. The top of the circular tube 12 is provided with a sealing end cover, the outer side of the upper end of the circular tube 12 is welded with a ventilation bent tube 11, and the lower end of the circular tube 12 is connected with the upper end cover of the cylinder 13. The lower end of the cylinder 13 is open, a flange 14 is arranged outside the cylinder 13, a rib plate 15 is arranged inside the cylinder 13, and the rib plate 15 divides the inside of the cylinder 13 into an upper space and a lower space.
The energy capturing part 2 is structurally shown in fig. 1, 2 and 3, and the energy capturing part 2 mainly comprises a buoy 23, a vertical rod 21, a damping disc 22 and a rack 24. The buoy 23 is of a closed cylinder structure, the upper end of the buoy is connected with the rack 24, the lower end of the buoy is connected with the vertical rod 21, and the lower end of the vertical rod 21 is connected with the damping disc 22. The energy capturing component 2 is arranged in the cylinder 13, wherein the buoy 23 is positioned below the rib plate 15, and the rack 24 penetrates through the rib plate 15 and extends upwards into the circular tube 12.
The structure of the flexible transducer device 4 is shown in fig. 3, 4, 5, 6 and 7, and the flexible transducer device 4 is made of a flexible dielectric material, which refers to a dielectric elastomer, such as a titanium dioxide functionalized graphene filled polyurethane dielectric elastomer.

Therefore, the flexible energy conversion device 4 forms a closed structure between the cylinder 13 and the buoy 23, so that the parts above the flexible energy conversion device 4 are isolated from the seawater, the corrosion of the seawater to the device parts is avoided, and the stability and the service life of the device are prolonged. The outer edge of the flexible transducer device 4 is provided with an electrode terminal 41, and the electrode terminal 41 is electrically connected with a charging device of the electronic control system 5.
As shown in fig. 8, to restrict the maximum displacement of the energy capture member 2 relative to the barrel 13, a boss 25 is attached to the upper end of the rack 24. The spring a61 is fixedly mounted on the top sealing end cap of the tube 12 and the spring b62 is fixedly mounted on the bottom of the tube 12. The rack 24 moves up to the upper limit position with the boss 25 contacting the spring a61, and moves down to the lower limit position with the boss 25 contacting the spring b 62.
The rigid transducer mechanism 3 is constructed as shown in fig. 3 and 9, and includes: a first drive shaft 301, a first straight gear 302, a first one-way bearing 303, a first worm 304; an energy storage shaft 311, a coil spring 312, a connecting block 313, an energy storage worm gear 314 and a shaft gear 315; a worm wheel shaft 321, a worm wheel 322, a gear 323 with missing teeth, a second one-way bearing 325, a first bearing seat 324; a second driving shaft 332, a second spur gear 334, a third one-way bearing 333, a second worm 331, a fourth one-way bearing 335, and a second bearing seat 336.
The first driving shaft 301 is in interference fit with an inner ring of the first one-way bearing 303, and an outer ring of the first one-way bearing 303 is fixedly connected with a central hole of the first straight gear 302. The first spur gear 302 and the second spur gear 334 are engaged with the rack 24. The first driving shaft 301 is coaxially and fixedly connected with a first worm 304, the first worm 304 is matched with a worm wheel 322, and transmission between the first worm 304 and the worm wheel 322 has self-locking performance. Thus, the worm wheel 322 can only rotate counterclockwise under the driving of the first worm 304, but can not rotate the first worm 304 reversely. The worm wheel 322 is fixedly connected to one end of the worm wheel shaft 321, the middle of the worm wheel shaft 321 is fixedly connected to the gear 323 with missing teeth, the other end of the worm wheel shaft 321 is in interference fit with an inner ring of the second one-way bearing 325, and an outer ring of the second one-way bearing 325 is fixedly connected to the first bearing seat 324. The gear 323 without teeth is matched with the shaft gear 315, the shaft gear 315 is located at one end of the energy storage shaft 311, the other end of the energy storage shaft 311 is sleeved with an energy storage worm gear 314 in a hollow manner, a connecting block 313 is arranged on the outer edge of the energy storage worm gear 314, the connecting block 313 is connected with the outer end of the coil spring 312, the inner end of the coil spring 312 is connected to the energy storage shaft 311, and the energy storage shaft 311 is connected with a generator shaft of the electric control system 5.
One end of the second driving shaft 332 is fixedly connected with the second worm 331, the second worm 331 is meshed with the energy storage worm wheel 314, and the transmission between the second worm 331 and the energy storage worm wheel 314 has self-locking performance. The self-locking property means that: when the lead angle of the worm is smaller than the equivalent friction angle between the meshing gears, the mechanism has self-locking performance, and can realize reverse self-locking, namely, the worm can only drive the worm wheel, but not the worm wheel can drive the worm. Therefore, the energy storage worm wheel 314 can only rotate counterclockwise under the driving of the second worm 331, but cannot rotate the second worm 331 reversely. When the second worm 331 is stationary, the accumulator worm gear 314 is also stationary. The other end of the second driving shaft 332 is in interference fit with an inner ring of the fourth one-way bearing 335, and an outer ring of the fourth one-way bearing 335 is fixedly connected with an inner hole of the second bearing seat 336. The middle part of the second driving shaft 332 is in interference fit with the inner ring of the third one-way bearing 333, the outer ring of the third one-way bearing 333 is fixedly connected with a second straight gear 334, and the second straight gear 334 is meshed with the rack 24. The first bearing block 325 and the second bearing block 336 are fixed to the fixed cylinder 1 by welding.
As shown in fig. 10, the electronic control system 5 mainly includes: the charging device, the generator and the charging and discharging control circuit; the electrode terminal of the flexible energy conversion device 4 and the generator are connected with a charging device, and the charging device rectifies and stabilizes electric energy generated by the flexible energy conversion device 4 and the generator and stores the electric energy in the battery. The charging device is connected with the charging and discharging control circuit, and the charging and discharging control circuit controls the output and the input of electric energy, so that overcharging and overdischarging are avoided. The generator shaft is connected with the energy storage shaft 311, and mechanical energy is converted into electric energy to be output.
The electric control system 5 is used for converting wave energy collected by the flexible energy conversion device 4 and the rigid energy conversion mechanism 3 into electric energy to be output or stored. The functions and effects of the electronic control system can be completely realized by using related equipment and principles in the prior art, and the specific structure of the electronic control system is not the technical problem to be solved by the invention and is not described in detail herein.
The invention provides a wave energy power generation device with a flexible transduction-sealing structure, which has the following working principle: the wave energy power generation device with the flexible transduction-sealing structure is connected to an ocean platform through a flange 14, and under the action of waves, a damping plate 22 drives a buoy 23 to move up and down in a cylinder 13 through a vertical rod 21. When the energy capturing member 2 moves downward, the first spur gear 302 and the second spur gear 334 are driven by the rack 24 to rotate clockwise and counterclockwise, respectively, and the clockwise direction is defined as the direction indicated by the arrow in fig. 9. Due to the unidirectional transmission function of the first unidirectional bearing 303 and the third unidirectional bearing 333, the first spur gear 302 and the second spur gear 334 can drive the first driving shaft 301 and the second driving shaft 332 to rotate clockwise only when rotating clockwise, and the first spur gear 302 and the second spur gear 334 cannot transmit torque to the first driving shaft 301 and the second driving shaft 332 when rotating counterclockwise. Therefore, when the energy capture member 2 moves downward, the second spur gear 334 idles with respect to the second drive shaft 332, i.e., the second drive shaft 332 is stationary. The first worm 304 drives the worm wheel 322 and the worm wheel shaft 321 to rotate counterclockwise while the first driving shaft 301 rotates clockwise. Due to the constraint effect of the second one-way bearing 325 on the clockwise rotation of the worm gear shaft 321, the worm gear shaft 321 can only rotate counterclockwise relative to the first bearing seat 324, and the worm gear shaft 321 drives the gear with missing teeth 323 to drive the shaft gear 315 to rotate, thereby driving the energy storage shaft 311 to rotate clockwise. Because the inner end of the coil spring 312 is fixedly connected with the energy storage shaft 311 which rotates clockwise, and the outer end of the coil spring is stationary, the conversion of the wave energy to the potential energy of the coil spring 312 in the downward moving process of the energy capture component is completed through the clockwise rotation of the inner end of the coil spring.
When the energy capturing member 2 moves upward, the first spur gear 302 rotates counterclockwise and the second spur gear 334 rotates clockwise, and according to the transmission analysis described above, the second driving shaft 332 rotates clockwise and the first driving shaft 301 is stationary. The second driving shaft 332 drives the second worm 331 to rotate clockwise, and the energy storage worm wheel 314 meshed with the second worm 331 rotates counterclockwise. The outer end of the coil spring 312 is fixed on the connecting block 313 on the outer edge of the energy storage worm gear 314 and rotates along with the energy storage worm gear 314 in a counterclockwise mode, and the inner end of the coil spring 312 is still, so that conversion of wave energy to potential energy of the coil spring 312 in the floating process of the energy capturing component is completed through the counterclockwise rotation of the outer end of the coil spring. Thus, the energy capturing component 2 can store energy for the coil spring 312 no matter upwards floating or downwards moving. When the tooth-missing position of the tooth-missing gear 323 rotates to a meshing interval with the shaft gear 315, the energy storage shaft 311 rotating clockwise is out of constraint, potential energy accumulated by the coil spring 312 is released to drive the energy storage shaft 311 to rotate reversely, and a generator in the electric control system 5 is driven to generate electricity. Due to the self-locking property of the transmission between the second worm 331 and the energy storage worm wheel 314 which is sleeved on the energy storage shaft 311, only the energy storage shaft 311 connected with the inner end of the coil spring 312 rotates anticlockwise in the potential energy release process of the coil spring 312, the energy storage worm wheel 314 connected with the outer end of the coil spring keeps static, and the energy storage shaft 311 drives the generator shaft to generate electricity in the anticlockwise direction all the time.
When the energy capturing component 2 moves up and down, the rigid energy conversion mechanism 3 works, and meanwhile, the flexible energy conversion device 4 also generates elastic deformation along with the up-and-down movement of the buoy 23 and is electrically connected with the power generation device of the electric control system 5 through the electrode terminal 41, and finally, the elastic potential energy of the flexible energy conversion device 4 is converted into electric energy to be output by using the power generation device of the electric control system 5.
According to the technical scheme provided by the invention, the flexible transduction device is used as a wave energy conversion and output device, and the rigid transduction mechanism can be sealed, so that the working reliability of the system is improved. The rigid energy conversion mechanism can collect and store wave energy in the coil spring, and elastic potential energy in the coil spring is periodically released and converted into electric energy. According to the wave energy power generation device, the rigid transduction mechanism and the flexible transduction device are organically combined, wave energy is fully converted into electric energy in multiple transduction modes, the output value of the electric energy is improved, and the simplification of the transduction device is realized.
