ENERGY HARVESTING INSTALLATION USING A RAINWATER

摘要

Disclosed is an energy harvesting device using rainwater that can easily convert rainwater energy into electrical energy as an integrated structure in the present invention. Energy harvesting apparatus according to the present invention, in the energy harvesting apparatus for converting to electrical energy using the falling energy of rainwater, rainwater receiving portion for receiving rainwater falling to the ground is uniformly arranged on the outer peripheral surface, A rotating body having a cylindrical structure to form rotational power under the load of received rainwater; A pressing device extending from the rotating shaft of the rotating body and having a plurality of protrusions to convert rotational power into impact energy; A piezoelectric device installed at a position close to the pressing device and converting shock energy into electrical energy by projection of the pressing device; And a mounting panel for supporting the piezoelectric device and the rotating body in an integrated structure. Therefore, the present invention provides the effect of simplifying the system and increasing the cost-effectiveness of equipment by performing power generation by storing rainwater and dropping the stored rainwater in a predetermined amount. In addition, in the present invention, due to the simplification of the system, there is an effect that can be easily installed and utilized in a place requiring a small amount of power.
