Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a wind energy raindrop energy composite energy collection device. Background technique [0002] At present, the micro-energy technology based on environmental energy acquisition and conversion mainly includes the conversion of solar energy, thermal energy, wind energy, vibration energy and other energy into electrical energy. [0003] Among them, solar power generation technology is relatively mature, but there are still problems such as high cost, low conversion efficiency, restrictions by natural conditions such as day and night, season, geographical latitude and altitude, and difficulty in using it in cloudy, cloudy and rainy weather. Especially in some tropical rainforest areas and rainy cities, solar power generation has been greatly restricted. In addition to solar energy, wind energy and raindrop energy are abundant in nature, clean and renewable, and can adapt t...

AI Technical Summary

Problems solved by technology

Existing raindrop energy collectors use the friction between raindrops and films to generate power, but the stability of friction power generation is also related to whether the rainfall continues. If the rain is intermittent, it will be difficult to continue

Therefore, only one form of energy conversion is used to collect raindrop energy, and the power generation efficiency is low and the stability is poor.

[0006] There are many kinds of energy in the natural environment, such as solar energy, wind energy, ocean energy, vibration energy, raindrop energy, etc., but the existing small energy harvesting devices generally can only collect a certain form of energy for power generation, such as the existing technology However, in some weather conditions, wind energy is often accompanied by raindrop energy, which will cause one of the energies to be unable to be effectively used, and the energy capture efficiency is relatively low. low power generation efficiency
