Embodiment Construction

[0040] Below in conjunction with accompanying drawing, the present invention will be further described:

[0041] The magnetostrictive sheet float type wave vibration power generation device of the present invention takes the giant magnetostrictive sheet as the core component, drives the fixed block to swing up and down through the transmission shaft to provide vibration for the giant magnetostrictive sheet, and adopts the pickup coil to convert the change of magnetic flux As the voltage, the process of converting the vibration energy in the wave undulating motion into electrical energy output is realized. The working principle of the device of the present invention is: when the floating body swings up and down under the action of waves, the transmission shaft will move, and the fixed block will be driven to move up and down, and the giant magnetostrictive sheet will also vibrate at the same time. Inverse effect (Villari effect), the vibration will cause the magnetization state...

Abstract

The invention relates to a float-type wave vibration generating device for a magnetostriction slice. The overall structure of the float-type wave vibration generating device is a symmetrical structure. The float-type wave vibration generating device comprises a fixing block. A transmission shaft sequentially penetrates through a floating body, a supporting plate, a lower end plate, the fixing block and an upper end plate from bottom to top. The fixing block is fixed to the transmission shaft in an interference-fit mode, and the upper end plate and the lower end plate are connected through a centrosymmetric supporting shaft. Two guide rods penetrate through through holes in the two ends of the fixing block correspondingly. An upper spring and a lower spring are vertically arranged on the guide rods in a sleeving mode. One end of the super-magnetostriction slice is fixed into a rectangular groove in the side face of the fixing block, and the other end of the super-magnetostriction sliceis provided with a mass block. A pick-up coil is wound on the super-magnetostriction slice. The transmission shaft drives the fixing block to swing vertically to provide vibration for the super-magnetostriction slice, electric energy generated in the generating process is picked up through the pick-up coil, and the energy collecting process for converting vibration energy generated in the wave fluctuation motion process into the electric energy to be output is achieved.

Description

technical field [0001] The invention belongs to the field of vibration power generation, and in particular relates to a magnetostrictive sheet float type wave vibration power generation device which converts wave vibration into electric energy. Background technique [0002] With the rapid development of human society, energy issues have become the biggest challenge facing mankind in the 21st century. As the largest treasure trove of resources on earth, the ocean contains tidal energy, wave energy, and wind energy, all of which are renewable energy sources. Wave energy is one of the most abundant energy sources in marine energy, and it is an energy source with high energy density. The development of wave energy has become an upsurge in the development of new energy. [0003] Magnetostrictive material is a new type of rare earth functional material that appeared in the 1970s. It is a magnetic (electrical) mechanical conversion material with a magnetostrictive effect. Its satu...
