Description

파력 발전을 위한 일방향 회전력 발생 장치 및 이를 이용한 파력 발전 장치One-way rotational force generating device for wave power generation and wave power generating device using the same
본 발명은 파력 발전을 위한 일방향 회전력 발생 장치 및 이를 이용한 파력 발전 장치에 관한 것이다.The present invention relates to a one-way rotational force generating device for wave power generation and a wave power generating device using the same.
최근 전력은 일반적으로 석유, 화석연료 및 원자력 등을 이용하여 생산되고 있으나, 석유 및 화석연료는 그 매장량이 한정되어 있어 시간이 지남에 따라서 고갈될 우려가 있고, 원자력의 경우에는 우라늄의 고갈로 이용기간에 한계가 있을 뿐만 아니라 핵폐기물의 처리가 심각한 문제로 대두되고 있는 상황이다.Recently, electricity is generally produced using petroleum, fossil fuels, and nuclear power, but oil and fossil fuels have limited reserves, so there is a risk of depletion over time. Not only is the period limited, but the disposal of nuclear waste is emerging as a serious problem.
전술한 석유, 화석연료 및 원자력을 이용한 발전의 문제를 대처하기 위해 풍력과 태양열을 이용한 신재생 에너지에 대한 연구와 개발이 활발히 이루어지고 있다. 풍력과 태양열을 이용한 발전은 에너지원이 사실상 무한하고, 환경오염이 적은 장점이 있다.In order to cope with the above-mentioned problem of power generation using petroleum, fossil fuel, and nuclear power, research and development on renewable energy using wind power and solar heat are being actively conducted. Power generation using wind and solar heat has the advantage of virtually unlimited energy sources and less environmental pollution.
그러나 풍력의 이용한 발전의 경우 바람의 세기가 계절과 위치에 따라 매우 달라 최적의 위치를 찾아내기 쉽지 않은 문제가 있었다. 또한, 태양열을 이용한 발전의 경우에는 일조량이 날씨와 장소에 따라 매우 달라질 뿐만 아니라, 저녁과 밤에는 일조량이 제한적인 문제가 있었고, 이러한 문제를 해소하기 위해 대규모 장치 및 효율적인 에너지 변환기술이 요구됨에 따라 생산비가 매우 커지는 단점이 있었다.However, in the case of power generation using wind power, there is a problem in that it is not easy to find the optimal location because the strength of the wind is very different depending on the season and location. In addition, in the case of solar power generation, the amount of sunlight varies greatly depending on the weather and place, and there is a problem in that the amount of sunlight is limited in the evening and at night. In order to solve this problem, large-scale devices and efficient energy conversion technology are required. The disadvantage is that the production cost is very high.
한편, 최근에는 전술한 신재생 에너지 중 파력을 이용한 발전 기술의 연구 및 개발이 활발히 이루어지고 있다. 파력 발전은 에너지원을 원활하게 수급 받기 위한 계절, 시간 및 장소에 따른 제한이 상대적으로 적은 장점이 있다.On the other hand, in recent years, research and development of power generation technologies using wave power among the aforementioned renewable energy have been actively conducted. Wave power generation has the advantage of having relatively few restrictions depending on the season, time, and place for smooth supply and demand of energy sources.
그러나 파력 발전은 발전효율이 파도의 파고(wave height), 주기(wave period) 및 파향(wave direction)에 따라 크게 영향을 받는 문제가 있었다.However, wave power generation has a problem in that power generation efficiency is greatly affected by wave height, wave period, and wave direction.
이를 해결함으로써 파력 발전의 효율을 향상시키기 위한 연구 및 개발이 활발하게 이루어지고 있으나, 종래 기술에 따른 파력 발전기는 모터 제어 및 에너지 변환 과정에서 발전 효율이 다소 낮아지는 문제가 있었다.By solving this problem, research and development are being actively conducted to improve the efficiency of wave power generation, but wave power generators according to the prior art have a problem in that power generation efficiency is somewhat lowered during motor control and energy conversion.
본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 파도를 이용하여 에너지를 효율적으로 발생시킬 수 있도록 파도를 이용하여 직선 왕복 운동을 발생시키고, 발생시킨 직선 왕복 운동을 양방향 회전 운동으로 변환시킨 다음 양방향 회전 운동을 일방향 회전 운동력으로 변환함으로써 효율적으로 에너지를 발생시킬 수 있는 파력 발전을 위한 일방향 회전력 발생 장치 및 이를 이용한 파력 발전 장치를 제공하는데 그 목적이 있다.An object of the present invention is to solve the above problems, to generate linear reciprocating motion using waves so as to efficiently generate energy using waves, convert the generated linear reciprocating motion into bi-directional rotational motion, and then Its purpose is to provide a one-way rotational force generating device for wave power generation that can efficiently generate energy by converting bidirectional rotational motion into one-way rotational motion and a wave power generation device using the same.

As the output is output and the generator is driven, more efficient wave power generation can be achieved.

When the frame moves by waves, the first linear motion unit performs linear reciprocating motion, the power transmission unit transmits the linear reciprocating motion of the first linear motion unit to the second linear motion unit, and the linear reciprocating motion of the second linear motion unit is transmitted to the one-way rotational force generating unit. By receiving the transmission, the one-way rotational force generation unit generates rotational force to drive the power generation unit to generate energy.
