Energy Harvesting Device Based On Wake Galloping Utilizing Corrugated Flat Column

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wake galloping-based energy harvesting apparatus using a corrugated flat plate, comprising: a fixing stand erected on an upstream side; And an exciter standing up and fixed to each other in parallel to each other so as to be spaced apart from the fixing table in a downstream direction so as to generate vibration by a wafer galloping phenomenon, wherein the exciter has a predetermined mass; A corrugated flat pillar extending from the lower side of the vibrating body and fixing the vibrating body so that the vibrating body can be vibrated laterally; And a piezo film laminated on the bending outer circumferential surface of the corrugated flat plate and converting the vibration energy transferred to the corrugated flat plate column into electric energy, It can be easily and quickly applied according to the installation position by freely adjusting it according to the wind direction and wind speed of the wind which is located at the location of the excavated zone and by combining the corrugated flat plate with wrinkles at the bottom of the exciter By lowering the natural frequency through the wrinkle effect, it is possible to improve the energy harvesting efficiency by making it suitable for the low-frequency vibration device. In addition, the piezoelectric film, that is, the PVDF film is attached to the outer surface of the corrugated flat plate, It is possible to have a very high bending area without changing the power generation efficiency It can have the effect that.
