A wind power generation device based on multilayer dielectric elastomer film stacking

Abstract

The invention discloses a wind power generation device based on multilayer dielectric elastomer film superposition. The wind power generation device comprises a windmill, a disc-type cam mechanism, multilayer dielectric elastomer film superposition power generation units, a shell, a tail wing, a rotary body, a supporting tower column, a cable, a high-voltage starting circuit and an electric energycollecting device, wherein a windmill rotating shaft of the windmill is connected with a cam rotating shaft of the disc-type cam mechanism, and a plurality of cams are arranged on the cam rotating shaft; and of the multiple multilayer dielectric elastomer film superposition power generation units are distributed on the periphery of each cam, the cams rotate to drive the multi-layer dielectric elastomer film superposition power generation units to do periodic stretching and compression linear reciprocating motion, and conversion between mechanical energy and electric energy is realized by utilizing the shape change of the dielectric elastomer material. The wind power generation device has the advantages of being light in mass, high in energy density, simple in structure, low in cost, easyto maintain and the like; and meanwhile, the space utilization rate of the power generation units inside the power generation device is high, and the power generation efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generation device based on the stacking of multi-layer dielectric elastomer films. Background technique [0002] With the decrease of traditional energy, energy conservation and emission reduction and the development of new energy have become the fundamental way for countries all over the world to solve the current increasingly serious energy problems. The development and utilization of renewable energy has gradually attracted people's attention. Studies have shown that the annual wind energy that can be used on the earth alone is four times the current annual energy consumption of all countries in the world. However, according to current relevant reports, wind power only accounts for 1% of the total power generation, and wind power still has great potential for development. As a clean and renewable energy source, wind power plays an extremely importan...

Problems solved by technology

[0005] Most of the existing invention patents related to dielectric elastomer generators mostly use a crank linkage mechanism or an eccentric wheel mechanism, and generally can only stretch or compress the dielectric elastomer power generation unit in a single direction within a certain plane. Linear reciprocation Movement, the space utilization rate of the power generation unit inside the generator is not high, and the power generation efficiency is low
