Abstract

The invention provides a biomimetic fish-based flow-induced vibration energy collection device. The device comprises a base, a swing beam, a first tail stand column, a second tail stand column and a head stand column; the head stand column is arranged at the front end of the base, the first tail stand column and the second tail stand column are symmetrically arranged at the back end of the base, the top end of the first tail stand column and the top end of the second tail stand column are each provided with an amplification transducer, one end of the swing beam is fixed to the top end of the head stand column, the free end of the swing beam faces the two amplification transducers and is located between the two amplification transducers, the free end of the swing arm is provided with a beam-end permanent magnet, and wings are symmetrically arranged on the two sides of the swing arm. The device is novel and simple in structure and reasonable in design, bistable state offset is generated through magnetic force, water power is guided through the wings, conversion between water flowing and vibration is enhanced, vibration is converted into periodic magnetic force to act on the amplification transducers through the magnetic force, the higher electromechanical coupling coefficient is achieved, the energy density is increased, the reliability is high, insulating sealing is easy, and follow-up storage and usage of electric energy are promoted.

Description

technical field

[0001] The invention relates to a technology in the field of energy collection, in particular to a flow-induced vibration energy collection device based on bionic fish. Background technique

[0002] Energy harvesting devices harvest energy from fluids. Traditional wind power and hydropower devices mostly use rotating turbine devices, which have low energy density and large volume, and are not suitable for miniaturization. Vibration energy harvesting is an effective way to harvest fluid energy. Contents of the invention

[0003] Aiming at the defects of the prior art, such as low energy density, difficult insulation and sealing, no passive control and guiding hydrodynamic function, and unsuitability for underwater energy collection, the present invention proposes a flow-induced vibration energy collection device based on bionic fish.

[0004] The present invention is achieved through the following technical solutions:

[0005] The present invention compri...
