Apparatus for generating wave-force and generating system

The present invention relates to a wave power generator and a power generation system using the same. More particularly, the present invention relates to a wave power generation apparatus and a power generation system using the same, which are capable of generating electric power by simultaneously utilizing horizontal and vertical kinetic energy of waves that are frequently generated and dissipated in the ocean as one of the marine energy.

In general, marine energy is an energy due to temperature differences between tides, tides, tides, ocean currents, and seawater, and it is not only depleted enough to meet human energy demand, but also has no merits. It is possible to overcome problems such as shortage of energy resources and rising price of energy resources due to soaring energy demand, and also to overcome environmental pollution and global warming, which is one of the biggest problems of fossil energy currently used as the main energy source. Next generation energy source.

Therefore, various types of marine power generation methods that can generate electricity using marine energy have been developed and are being used experimentally. Such types of marine power generation methods include tidal power generation, wave power generation, temperature difference generation, Ocean current power generation, wind power generation, and salinity power generation.

As for the marine power generation method, tidal power generation is a method of generating electricity by turning a turbine using water level difference generated by confining the seawater introduced at high tide to a high reservoir and waterproofing at low tide. It is the same as the principle of hydro power in that respect.

Wave power generation is a method of acquiring power for power generation using up and down kinetic energy of waves. In the wave power generation device, a stationary wave power generation system that rotates a generator by causing a floating body on the surface to move up or down by blue movement. Floating wave power generation device that generates electricity by rotating turbine using the flow of air passing through the nozzle when the air in the air chamber is compressed and expanded due to the action of the device and the blue wave. .

The temperature difference generation is a generation method that uses the temperature difference of the seawater according to the water depth. In the tropical seas, the sea surface temperature is over 20 degrees, but it is hardly changed to about 4 degrees in the deep sea 500 ~ 1000m deep from the sea surface. The low boiling liquid is evaporated and cooled by using the temperature difference between the deep and deep layers, and the power is generated by using the pressure difference. The heat flows from a high temperature heat source to a low temperature heat source to drive a turbine to produce electric power.

Current-car power generation is a method of installing large propeller-type turbines in the sea and turning them using currents to generate electricity, just as wind drives huge windmills on land.

The opening and closing part 4 is opened so that the outside air flows into the air chamber 2 and the turbine 5 rotates as the air moves, and the generator 6 operates by the rotation of the turbine 5. Electricity is generated.
