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.
