In order to meet the requirement of experimental exploration, a plurality of groups of data are measured and compared, and the support rods (60) between the upper distance adjusting plate (63) and the lower distance adjusting plate (62) can be adjusted to be respectively matched with different through holes in the upper distance adjusting plate and the lower distance adjusting plate, so that the adjustment of the magnetic distance is realized. In order to meet the requirement of experimental exploration, a plurality of groups of data are measured and compared, and the supporting rods (45) between the upper distance adjusting plate (44) and the lower distance adjusting plate (47) can be adjusted to be respectively matched with different through holes in the upper distance adjusting plate and the lower distance adjusting plate, so that the adjustment of the magnetic distance is realized. The device magnetic spacing is adjustable, can obtain the experimental data of different groups through adjusting the magnetic spacing, satisfies the requirement of experimental design.

The magnetic spacing can be adjusted by changing the distance between the two support rods, so that different experimental data can be obtained. After a stable laminar flow field is introduced into the experiment platform, the piezoelectric energy harvesting device is placed in the experiment platform according to the installation method, cylindrical winding fluid vibrates in water, and relevant experiment data can be extracted by changing different experiment structures or different experiment parameters of the same structure and connecting output voltage with an oscilloscope.

The invention aims to provide an experimental device and an experimental method for a vortex-induced vibration piezoelectric energy harvester. The direct current push rod motor (12) can be used for controlling the extension of the push rod through a remote controller. In the face of a high-speed water flow environment, a hydropower station can be established to convert the kinetic energy of water flow into electric energy by using a turbine, but the turbine has certain requirements on the flow speed of the water flow (the turbine has higher utilization rate when the flow speed of the water flow is more than 2 m/s). 3) The water flow vortex-induced vibration piezoelectric energy harvesting device has diversified structures, can adapt to various flow velocity environments, can meet experimental requirements, and explores the most suitable piezoelectric energy harvesting structure at each flow velocity.

After water flow enters the water tank (2), the turbulence degree of the water flow is large, and the experimental effect is influenced. In order to keep the water flow in a stable laminar flow state, the water flow firstly passes through the honeycomb device (3), the honeycomb device is used for destroying the vortex of the original water flow to enable the vortex to be smoother, and then passes through the damping net (4), so that the turbulence degree of the water flow is further reduced. In order to allow the piezoelectric energy harvester to generate resonance at a lower excitation frequency and generate a vortex-induced resonance phenomenon in a lower-speed water flow environment, the first structure has the following structural characteristics: the piezoelectric cantilever beam (20) is perpendicular to the water flow surface and fixed, the free end of the piezoelectric cantilever beam (20) is connected with the upper end surface of the cylinder (29), and only the tail end cylinder (29) is immersed in water, so that the water insulation problem of the piezoelectric cantilever beam is not considered in the energy harvester, and the experimental condition is easy to realize.
