The invention discloses a multi-directional vibration power generating device. The multi-directional vibration power generating device comprises a multi-directional piezoelectric vibration energy collecting device. The multi-directional piezoelectric vibration energy collecting device comprises a base (41), a vibration rod (45) and at least three L-type piezoelectric power generation chips (42), wherein the vibration rod (45) is perpendicular to and is separated from the base (41), one end of each L-type piezoelectric power generation chip (42) is fixedly connected with the vibration rod (45), the other end of each L-type piezoelectric power generation chip (42) is fixedly connected with the base (41), and the L-type piezoelectric power generation chips (42) are evenly distributed on the periphery of the vibration rod (45). The multi-directional vibration power generating device collects vibration energy in all the directions and converts the vibration energy into electricity.
Description
technical field [0001] The invention relates to the field of tunnel engineering health monitoring, in particular to a multidirectional vibration power generation device. Background technique [0002] After the tunnel project is put into use, with the increase of the service life, the problem of structural aging has become increasingly prominent, and tunnel diseases have continued to develop. Affected by many factors such as operating environment, geological conditions, groundwater, construction quality and material properties, the distribution of tunnel diseases is discrete and time-sensitive. In view of the above-mentioned characteristics of tunnel diseases, higher requirements are put forward for the flexible arrangement, on-demand increase and decrease, and continuous operation of tunnel health monitoring sensors. [0003] Existing wireless sensors for structural monitoring generally adopt two modes of external circuit power supply and battery power supply. However, at ...
