Abstract

The invention discloses a piezoelectric electromagnetic composite wave floating energy device with vortex-induced bluff body vibration, and relates to the technical field of wave power generation. Thedevice comprises a wave energy collection structure and a vortex-induced vibration power generation structure. The wave energy collection structure is used for converting wave energy into gas oscillatory waves and comprises a gas chamber, a connecting sleeve and a cylindrical ventilation pipeline which are sequentially connected from bottom to top, wherein the cylindrical ventilation pipeline isused for transmitting the gas oscillatory waves to the vortex-induced vibration piezoelectric power generation structure; the vortex-induced vibration piezoelectric power generation structure is located in the cylindrical ventilation pipeline and comprises a cantilever beam supporting frame, a cantilever beam fixing base, a cantilever beam and a vortex-induced bluff body power generation structure. By modification of the internal structure of the vortex-induced bluff body, an electromagnetic vibration power generation structure is designed in the vortex-induced bluff body to collect vibrationenergy of the bluff body in vortex-induced vibration to generate electric energy. The device has the advantages of being stable in power generation efficiency, capable of supplying power for a long time and high in energy conversion efficiency.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a piezoelectric electromagnetic composite wave buoyancy device for vortex-induced blunt body vibration. Background technique [0002] Ocean observation is the foundation of marine scientific research, and it is also an important starting point for global ocean science and technology competition. To understand the ocean, manage the ocean, and promote the construction of my country's ocean power is inseparable from the observation of the whole sea area. The basis for maintenance. Implementing the "transparent ocean" strategy, strengthening the development of ocean observation technology and equipment, and accelerating the construction of ocean observation systems are an important direction for ocean science and technology innovation. For ocean information monitoring, most of them are completed by buoys floating on the sea, and batteries are ocean monitoring buoy...
