本发明的工作原理：参见图1和图4，柔性电极1-2引出电极线1-3与电源E和储能电容Cs连接，将堆栈式介电弹性体波浪能量收集器置于水槽14中，电路中的微动开关S1断开，S2闭合，当液面上升时，拉杆11与刚性绳12使得压锤8的相对高度不会明显改变，浮体7通过支架腿6、支柱5、下板4、套筒2和上板3带动介电弹性体换能元件1向上运动，从而使得介电弹性体换能元件1被压缩，电容增大。当介电弹性体换能元件1被压缩到一定程度时，微动开关S1闭合，S2断开，高压电源E向介电弹性体换能元件1充电，电量恒定。当液面下降时，拉杆11与刚性绳12使得压锤8的相对高度不会明显改变，浮体7通过支架腿6、支柱5、下板4、套筒2和上板3带动介电弹性体换能元件1向下运动，从而使得介电弹性体换能元件1恢复初始形状，电容减小。由于介电弹性体换能元件1两端电量恒定，使得其两端电压升高，所存储电能升高。与此同时，微动开关S2瞬时闭合，S1断开，介电弹性体换能元件1(Cg)将其电能存入储能电容Cs中。至此完成一次机械能到电能的转换。当水面产生连续波动时，以上过程会循环往复出现，从而完成一次又一次的机械能到电能。Working principle of the present invention: referring to Fig. 1 and Fig. 4, the flexible electrode 1-2 leads the electrode line 1-3 to connect with the power supply E and the energy storage capacitor C s , and the stacked dielectric elastomer wave energy harvester is placed in the water tank 14 In the circuit, the microswitch S1 in the circuit is disconnected, and S2 is closed. When the liquid level rises, the pull rod 11 and the rigid rope 12 make the relative height of the pressure hammer 8 not change significantly, and the floating body 7 passes through the support leg 6 and the pillar 5 , the lower plate 4 , the sleeve 2 and the upper plate 3 drive the dielectric elastomer transducer element 1 to move upward, so that the dielectric elastomer transducer element 1 is compressed and the capacitance increases. When the dielectric elastomer transducer element 1 is compressed to a certain extent, the microswitch S1 is closed and S2 is turned off, and the high-voltage power supply E charges the dielectric elastomer transducer element 1 with a constant power. When the liquid level drops, the pull rod 11 and the rigid rope 12 make the relative height of the hammer 8 not change significantly, and the floating body 7 drives the dielectric elastomer through the support leg 6, the pillar 5, the lower plate 4, the sleeve 2 and the upper plate 3 The transducer element 1 moves downward, so that the dielectric elastomer transducer element 1 returns to its original shape, and the capacitance decreases. Since the electricity at both ends of the dielectric elastomer transducing element 1 is constant, the voltage at both ends increases, and the stored electric energy increases. At the same time, the micro switch S 2 is closed instantaneously, and S 1 is opened, and the dielectric elastomer transducing element 1 (C g ) stores its electric energy into the energy storage capacitor C s . At this point, a conversion from mechanical energy to electrical energy is completed. When the water surface fluctuates continuously, the above process will occur repeatedly, thus completing the mechanical energy to electrical energy again and again.
