Problems solved by technology

[0002] At present, the equipment and devices for energy harvesting based on piezoelectric ceramic materials mainly have the following problems: because piezoelectric ceramics are brittle, the piezoelectric materials in some energy harvesting devices are prone to fatigue fractures; The service life of the material increases, but it usually needs to be used with a booster mechanism, which is easy to change the original mechanical structure
[0005] But none of above-mentioned technical solutions solves the technical problem that prior art exists

Abstract

The invention discloses an energy acquisition experiment device. The energy acquisition experiment device comprises a rotation shaft (1), a rotation shaft support part (10) and an energy acquisition device, wherein the rotation shaft support part is used for supporting the rotation shaft so that the rotation shaft is rotated under an external force, the energy acquisition device is arranged on therotation shaft, the rotation shaft rotates so that alternating charge is generated on the energy acquisition device, and voltage output can be generated by the energy acquisition device.

Description

technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a piezoelectric energy collection experimental device for collecting the rotation of the self-weight of a rotor. Background technique [0002] At present, the equipment and devices for energy harvesting based on piezoelectric ceramic materials mainly have the following problems: because piezoelectric ceramics are brittle, the piezoelectric materials in some energy harvesting devices are prone to fatigue fractures; The service life of the material increases, but it usually needs to be used with a booster mechanism, which is easy to change the original mechanical structure. [0003] Some devices that use piezoelectric materials for energy harvesting are disclosed in the prior art, for example, the arc-shaped vibration energy harvesting device based on piezoelectric effect disclosed in the patent publication No. CN105305881B, which incl...
