Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a frequency-adjustable ultra-low frequency multi-directional shaking power generation device. Background technique [0002] In order to meet their own energy needs, human beings burn a large amount of fossil fuels, such as oil and coal. This process produces a large amount of greenhouse gases such as carbon dioxide, which exacerbates global warming and threatens human survival. Therefore, it is necessary to develop clean energy and improve energy utilization efficiency. At present, the development technology is relatively mature and clean energy mainly includes nuclear energy, solar energy, wind energy, water energy, and mechanical vibration energy; Difficulties in small, large-scale development. However, mechanical vibration is not affected by factors such as climate and environment, and is very common in human life. The difficulty of capturing technology is relatively lo...

Problems solved by technology

[0007] Environmental vibration is usually time-varying, and vibrations in different environments have significant differences in frequency characteristics, and most existing vibration power generation devices cannot adjust their own frequency response characteristics to adapt to different environmental vibrations; inertial force drive The vibration power generation device generally needs a mechanical connection mechanism to constrain the displacement of the vibrator. These mechanical connection mechanisms need to bear the impact of the reciprocating motion of the vibrator, which is the weak link of the whole system; the displacement-driven vibration power generation device uses a complex transmission device to convert the linear Vibrations are converted to rotational vibrations, a structural complexity that often makes it difficult for him to harvest vibrational energy in multiple directions
