POWER GENERATION MECHANISM AND SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a technology that extends a frequency region that enables vibration power generation and thereby effectively conducts power generation.SOLUTION: A vibration power generation device 10 includes: a housing part 20; a power generator 30; a vibration impact part 40; an elasticity adjustment part 50; and a spring 60. The vibration power generation device 10 is installed on a crosstie 90 etc. of a rail track. The power generator 30 is a magneto-striction type power generator and is subject to an impact caused by the vibration impact part 40 to generate power. An impact frame 41 of the vibration impact part 40 is a beam shaped elongated quadratic prism formed by a stainless steel material. An end part of the impact frame 41 at the right side in a figure is rotatably attached to a second support pillar 23 by a rotary shaft 42. An impact part 43 is attached to the other end part of the impact frame 41 (a free end side at the left side in the figure) facing upward. A weight 44 is attached to the impact frame 41. A spring 60 is attached so as to connect the impact frame 41 with a spring support frame 51.
