设计了一种基于介电弹性体阵列的风力能量转化装置,装置包括风车、曲轴、介电弹性体薄膜、外壳、轴承、夹具、电刷、高压发生器、电缆等。其中,风车的转轴与曲柄连杆的主轴颈连接,连杆轴颈上安装轴承,轴承外侧180°对向设置固定介电弹性体的夹具;介电弹性体另一侧同样使用夹具固定在外壳内表面,设置多段连杆轴颈,始终处于相同拉伸状态的介电弹性体发电单元并联组成一组发电阵列,提高单次发电量。本装置基于单个介电弹性体组成介电弹性体阵列,在1个周期内依次进行电能的转化。实验结果表明,在材料应变量达230%,充电电压为925 V时,单个周期内的发电量可达到17.06 mJ,为介电弹性体阵列大规模发电的应用提供参考。

A wind energy conversion device based on a dielectric elastomer array is designed,which includes a windmill,a crankshaft,a dielectric elastomer film,a casing,a bearing,a clamp,a brush,a high voltage generator,a cable,and the like.Among them,the rotating shaft of the windmill is connected with the main journal of the crank connecting rod,the bearing is mounted on the connecting rod journal,the fixture for fixing the dielectric elastic body is located 180°opposite to the outer side of the bearing,and the other side of the dielectric elastic body is also fixed in the outer casing by using the clamp.On the surface,a plurality of connecting rod journals are arranged,and dielectric elastomer power generating units which are always in the same tensile state are connected in parallel to form a group of power generating arrays,so as to increase the single power generation capacity.The device is based on a single dielectric elastomer to form a dielectric elastomer array,which sequentially converts electrical energy in one cycle.The experimental results show that the power generation in a single cycle can reach 17.06 mJ when the material strain reaches 230%and the charging voltage is 925 V.It provides a reference for the application of large-scale power generation of dielectric elastomer arrays.
