Description

System for wave power generation using reciprocating motion of magnetic sphere

The present invention relates to a wave power generation system using the reciprocating motion of magnetic spheres, and more particularly, when a generator placed in a floating state on the water surface according to the vertical motion of the waves is tilted by the energy of the waves, the magnetic spheres inside the system It relates to a wave power generation system using the reciprocating motion of a magnetic sphere that moves in the direction of gravity and produces electricity by generating electromagnetic induction and a coil surrounding the outside.

Due to the depletion of fossil fuels and environmental problems caused by existing fuels, the field of developing alternative energy has recently been in the spotlight.

Renewable energy is a renewable energy, and since most of it uses the power derived from natural phenomena, it has the advantage of not being depleted and the emission of pollutants is small compared to fossil fuels.

In addition, since fossil fuels are concentrated in specific deposit areas, countries that do not belong to that region must import fuels, but renewable energy uses various types of energy such as solar energy, wind energy, and marine energy depending on the natural environment around the country. can be used, so the imbalance of energy distribution is less.

In the case of Korea, it has a geographical advantage suitable for using marine energy as a new and renewable energy because it is surrounded by the sea on three sides. According to the potential power generation potential of marine energy estimated by the International Energy Agency in 2011, in Korea, wave energy ranks second with an annual rate of 29,500 TWh, following the difference in sea temperature. However, the potential power generation potential of seawater temperature difference power generation precedes wave power generation, but it has the disadvantage of high initial installation cost and difficult installation.

Wave power generators for wave power generation are currently being developed in movable body type, frequency column type, and wall wave type.

In the case of a frequency column generator, the wave potential energy is converted into kinetic energy (air) and the converted energy is used again for kinetic energy (turbine) to produce electrical energy. An energy conversion process is required, and there is a problem in that the heat energy that escapes in the energy conversion process lowers the energy production efficiency.

In addition, the movable body type to which the present invention belongs is a method in which an object moves according to a change in the water surface to directly produce electricity. Compared to other methods, it is effective in terms of energy efficiency, but it is durable because the part receiving wave energy must be kept outside. There were problems with being vulnerable to corrosion and corrosion.
