振り子機構を用いた水産業ICT用途の揺動発電装置の提案

抄録

To introduce ICT to the fisheries industry, it is important to secure a power supply. To supplement solar power generation at night, on rainy days, and on cloudy days, we have devised a rocking electric power generator that generates electricity from the rocking motion of waves.

We report on the building up a rocking electric power generator. The generator can generate electricity by rocking motion. It achieved to 1.28VA rotational speed of 0.78rps, and the maximum output current is 40mA. The load resistance is available 240Ω or more. We clarified the relationship between rocking motion and power generation in a rocking power generator, using evaluation sensors each of motion and electricity.

As a result of increasing the power generation efficiency of the air gap generator, the load current also flows to the coil, which causes the electromagnetic brake to work more strongly. Due to the influence of the electromagnetic brake, it was not possible to increase the generated voltage. It was found that a driving torque by the pendulum load was required that exceeded the braking force produced by the electromagnetic brake. To increase the pendulum load, the float becomes to lose its balance because the center of gravity becomes higher. The relationship between the pendulum load and balance is important for stable levitation.
