Embodiment Construction
[0045] The present invention provides many applicable inventive concepts that can be embodied in numerous specific contexts. The specific examples described in the following embodiments of the present invention are only used as illustrations of specific embodiments of the present invention, and are not intended to limit the scope of the present invention.
[0046] First, the nouns involved in the present invention are explained.
[0047] Stress: When an object is deformed due to external factors (force, humidity, temperature field changes, etc.), an internal force that interacts with each part of the object is generated to resist the effect of this external factor and try to make the object change from the deformed position Returning to the position before deformation, the internal force per unit area at a certain point of the section under investigation is called stress.
[0048] State of stress: The stress at a point in an object in all possible directions is called the sta...

The invention discloses a wind power generation device based on dielectric elastomers. The wind power generation device (100) comprise a base plate (1), a support (2), the dielectric elastomers (3), a windmill assembly (4) and connecting rods (5). The support (2) and the dielectric elastomers (3) are all arranged on the base plate (1). The windmill assembly (4) is arranged on the support (2). One ends of the connecting rods (5) are connected with the dielectric elastomers (3), and the other ends of the connecting rods (5) are driven by the windmill assembly (4). The windmill assembly (4) rotates and drives the connecting rods (5) to move in a reciprocating manner, so that the dielectric elastomers (3) are in a periodic compression and springback movement state, and the conversion of mechanical energy and electric energy is achieved. According to the wind power generation device, electricity is generated by the adoption of the periodic compression and springback movement state of the dielectric elastomers, direct coupling with an energy source is conducted, no intermediate conversion link is needed, the requirement on the movement frequency is avoided, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of energy power generation, in particular to a wind power generation device based on a dielectric elastomer. Background technique [0002] In recent years, with the development of communication technology, human's demand for electricity has been increasing day by day. At the same time, with the improvement of environmental protection awareness, the effective use of various clean energy has attracted widespread attention from the academic circle. [0003] As a clean and renewable energy, wind energy has huge reserves, and the global wind energy is about 2.74×10 9 MW, of which the available wind energy is 2×10 7 MW is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. [0004] A device that generates electricity from wind is called a wind turbine. At present, the working principle of wind turbines is electromagnetic, and the basic components include wind r...
