Problems solved by technology

Due to the non-renewability of fossil fuels, climate change, ecological damage and other issues, relying solely on traditional energy supply methods is unsustainable and brings serious energy security issues. It is urgent to adjust the energy structure and study renewable energy
[0003] The current wind power and hydropower convert the kinetic energy of the wind and the potential energy of water into electrical energy by electromagnetic generators, which have the following problems: ① Electromagnetic power generation equipment is usually complex in structure, expensive, and requires frequent maintenance, so the cost of power generation is relatively high; ② Wind power requires a speed-up mechanism, which is inefficient and increases structural complexity and cost; ③Traditional hydropower needs to build dams and change river beds, which not only requires a large investment, but also has a certain impact on the ecological environment
[0010] At present, except for SRI's research on dielectric EAP wave energy generators, there is no research report on dielectric EAP generators using fluid flow kinetic energy.

Embodiment Construction

[0021] The technical solution of the invention is described in detail below in conjunction with the accompanying drawings by taking the circular shell as an example:

[0022] figure 1 It is a structural block diagram of a fluid kinetic energy generator based on a dielectric EAP. It includes four parts: a shell, a fluid motion converting mechanism, a transducing unit deforming mechanism and a transducing unit array. The kinetic energy conversion mechanism of the fluid converts the motion of the fluid—wind and water flow into rotational motion, and drives the deformation mechanism of the energy conversion unit to rotate. The transformation mechanism of the transducer unit causes the dielectric type EAP in the transducer unit array to sequentially generate stretching and retraction deformations during the rotation process.

[0023] There are two realization forms of hydrokinetic generators based on dielectric EAP, namely axial type and radial type.

[0024] figure 2 Shown is...
