Description

Floating Wave Power Generator {FLOATING TYPE WAVE-POWER GENERATION APPARATUS}

The present invention relates to a wave power generation apparatus capable of producing electricity using wave force.

Due to the depletion of fossil fuels and environmental pollution caused by the use of fossil fuels, there is a growing interest in clean alternative energy.

Representatively, technologies for generating electricity using solar, wind, hydro, wave, and the like are known.

In particular, the wave power generator according to the present invention can be called an infinite clean resource because it generates electricity by using the continuous movement of sea level and potential energy.

On the other hand, a floating body is installed to monitor various marine observations and route markings to observe natural phenomena or to mark routes for safe navigation of ships.

Floating bodies installed at sea are moored to move in a limited area, and various equipments are provided inside and outside the floating bodies for the purpose of installing the floating bodies.

For example, a signal sign may be provided outside the float to display the route, observation equipment such as various sensors for ocean observation may be mounted, and a data logger for storing or storing measured information may be provided. Can be prepared.

The battery must be placed inside the float because electricity must be supplied to operate the equipment provided in the float. However, since the battery is discharged after a certain time to supply electricity, there is a problem that the battery must be replaced periodically.

In order to solve this problem, a floating battery is used as a rechargeable battery, and a technology for charging a rechargeable battery through a solar panel is known. However, solar panels installed outside the floating body can produce electricity only during the day, when there is a bad weather such as cloudy days there is a problem that can not produce electricity for a long time.

In addition, since the solar panel collides with the sailing vessel and can be easily broken and continuously exposed to salt, there is a problem that performance decreases with time. In addition, there is a problem in that the cost of replacing the damaged or degraded solar panels or maintenance costs too much.

On the other hand, due to the limitation that marine power generation facilities installed near the coast on a large scale require enormous cost and time from design to fabrication and installation, and are limited to locations where high waves occur at all times. There is a problem in that it is unsuitable as an electric power supply device for a floating body having a purpose for small ocean observation.
