WAVE MOTION POWER GENERATING DEVICE

PROBLEM TO BE SOLVED: To sharply improve power generation efficiency by converting a vertical motion of wave motion into a large horizontal displacement in a power generating device utilizing the wave motion.SOLUTION: A wave motion power generating device includes: a floating body 1 which floats on water; a pendulum body 2 which is hung down and supported on the floating body 1 and performs a circular arcuate motion around a support part 12 as a center with respect to a floating body 1 upper part in accordance with the vertical motion by means of waves of the floating body 1; a permanent magnet 3 which is provided on the pendulum body 2 and has a substantially circular-arcuate shape part 31 around the support part 12 as a center; and a coil body 4 which is fixed to the floating body 1 and has a substantially circular-arcuate shape part 41 which goes along the substantially circular-arcuate shape part 31 of the permanent magnet 3 while approaching it. Concretely, a support 11 built on the floating body 1 is provided, the pendulum body 2 is hung down and supported on an upper part of the support 11 and the coil body 4 is fixed onto a lower part of the support 12.SELECTED DRAWING: Figure 1 【課題】波動を利用した発電装置において、波動の上下運動を大きな水平移動に変換して、発電効率を大幅にアップする。【解決手段】水上に浮く浮体１と、その浮体１上に吊り下げ支持されて、浮体１の波による上下運動に伴い、浮体１上に対する支持部１２を中心に円弧運動する振子体２と、その振子体２に設けられ、前記支持部１２を中心とする略円弧形状部３１を有する永久磁石３と、浮体１に固定されて、永久磁石３の略円弧形状部３１に接近して沿う略円弧形状部４１を有するコイル体４と、を備える。具体的には、浮体１上に建てられた支柱１１を備え、その支柱１１の上部に振子体２が吊り下げ支持されて、支柱１２の下部にコイル体４が固定される。【選択図】図１
