Embodiment Construction

[0052] The present invention will be further explained below in conjunction with the drawings:

[0053] The giant magnetostrictive instantaneous impact energy collection and warning system of the present invention uses a giant magnetostrictive material sheet 9 as a core element, and uses a pickup coil 8 to convert changes in magnetic flux into voltage, thereby realizing the generation of The process of converting the vibration energy into electrical output. The working principle of the giant magnetostrictive instantaneous impact energy collection and warning system is: the rotary motion of the crank 3 drives the slider 5 to make a linear reciprocating motion, hammering the L-shaped plate 13 with the giant magnetostrictive material sheet 9 and wrapping it The giant magnetostrictive material sheet 9 of the pickup coil 8 is subjected to vibration, and the vibration will cause the magnetization state inside the giant magnetostrictive material sheet 9 to change, that is, the internal ...

Abstract

The invention belongs to the field of vibration collection and utilization, and relates to a giant magnetostrictive instantaneous impact energy collection and warning system by taking giant magnetostrictive sheet materials as core elements and generating electric energy by absorbing vibration. One end of the crank of the system is installed on the platform, the other end of the crank is connectedwith a sliding block arranged on the platform through a connection rod, an L-shaped plate is connected with the platform, a giant magnetostrictive material sheet is fixed on the L-shaped plate, a pickup coil winds the giant magnetostrictive material sheet, the wire end of the pickup coil is connected with the input end of a rectifying filter circuit board, the output end of the rectifying filter circuit board is connected with the input end of a lithium battery, and the output end of the lithium battery is connected with a warning lamp. The pickup coil is configured to pick up the electric energy generated in the power generation process to achieve the energy collection and utilization process of converting vibration energy generated in the instantaneous impact process into energy output.

Description

Technical field [0001] The invention belongs to the field of vibration collection and utilization, and relates to a giant magnetostrictive instantaneous impact energy collection and warning system that generates electric energy by absorbing vibration with giant magnetostrictive sheet material as the core element. Background technique [0002] Giant magnetostrictive materials were discovered in the 1970s. Because most of them are rare earth structures, they are also called rare earth giant magnetostrictive materials. This material can realize the two-way conversion of energy between machine-magneto-electricity. The magnetostrictive inverse effect refers to the process of ferromagnetic material being deformed by external vibration, the magnetic flux density inside the material will change, combined with the Faraday electromagnetic effect, the changing magnetic flux density can be converted into electrical energy. In this process In, giant magnetostrictive materials realize the conv...
