Omnidirectional wind energy collector

Abstract

The invention provides an omnidirectional wind energy collector which comprises a fixed base, a cylindrical elastic cantilever beam is arranged on the fixed base, the bottom end of the cylindrical elastic cantilever beam is fixed through the fixed base, the top end of the cylindrical elastic cantilever beam is connected with an oscillation device, and the oscillation device can be a hollow cylinder, a hollow square column or a column with an X-shaped cross section; and a piezoelectric ceramic circular tube fixedly sleeves the cylindrical elastic cantilever beam. The omnidirectional wind energy collector is simple in structure, convenient to assemble, small in size and convenient to integrate, and the application of the wind energy collector in the self-energy-supply field is facilitated; compared with a bluff body structure with a conventional section shape, the oscillation device structure with the X-shaped cross section can increase the vibration amplitude of the energy collector, improve the energy collection efficiency and improve the utilization rate of wind energy; the wind energy collector based on the piezoelectric ceramic circular tube and the cylindrical elastic cantilever beam can respond to wind in different directions in the natural environment, outputs high electric energy and has high environmental adaptability.

Description

technical field [0001] The invention relates to the technical field of wind power generation and energy collection, in particular to an omnidirectional wind energy collector. Background technique [0002] With the widespread application of wireless sensors and portable electronic devices in wireless sensor networks and microelectromechanical systems (MEMS), energy supply has increasingly become a major bottleneck hindering their development. As a clean energy that exists widely in nature, wind energy is a hotspot in the research of self-supply energy at home and abroad. Compared with the rotating small wind energy harvester, the wind-induced vibration energy harvester has a simple structure and is easy to miniaturize, which is the main direction of wind energy harvester development. The wind energy harvester based on wind-induced vibration collects wind energy by using the structure's vortex-induced vibration, flutter, galloping, and wake galloping. The conversion methods ...
