Abstract

A self-generating apparatus of a vessel is provided to obtain clean energy without causing environmental pollution by self-generation using the vertical motion of the vessel due to the wave energy. A self-generating apparatus of a vessel(10) using wave energy includes an anchor(30) and a self-generator(40). The anchor is fixed to the bottom of the sea by a mooring device(20) and an anchor chain(32) installed on the bottom of the vessel. The self-generator is connected to the anchor via a fixing rope(34) passing through an opening(12) formed on the bottom of the vessel. The self-generator includes a magnet(50), a coil(60), and an electric storage device. The magnet is fixed at a predetermined position inside the self-generator. The coil is wound around the magnet to generate induced electromotive force through the vertical motion of the hull due to the wave energy. The electric storage device converts the induced electromotive force generated by the coil into electric energy to store the converted electric energy.

본 발명은 파랑에너지를 이용한 선박의 자가 발전장치에 관한 것이다. 더욱 상세하게는 파랑에너지로 인해 필연적으로 생기는 선박의 상하운동을 이용하여 전기를 발생시키는 선박의 자가 발전장치에 관한 것이다.The present invention relates to a self-generating device of a ship using wave energy. More specifically, the present invention relates to a ship's self-generating device that generates electricity by using up and down motion of a ship inevitably caused by wave energy.

선박에는 많은 양의 전기에너지가 필요하다. 이러한 에너지는 석유나 디젤유를 태워서 얻을 수 있으며, 그 비용 또한 막대하다. 일반적으로, 전기를 생산하기 위한 시설로서 화력, 원자력, 수력, 풍력, 조력 등을 이용하는 다양한 발전시스템이 알려져 있다. 초기의 발전시설로는 수력을 가장 많이 사용되었으며, 수력발전은 무공해한 클린에너지로서 현재도 세계 각국에서 널리 사용하고 있다.Ships need a lot of electrical energy. This energy can be obtained by burning petroleum or diesel oil, and the cost is enormous. In general, various power generation systems using thermal power, nuclear power, hydropower, wind power, tidal power, etc. are known as facilities for producing electricity. In the early power generation facilities, hydropower was used the most, and hydropower is pollution-free clean energy and is still widely used in various countries around the world.

그러나 수력의 경우에는 낙차를 이용할 수 있는 지형 및 발전이 가능한 수량을 필요로 하므로 일반적으로 험한 산속에 건설되어 수요자에서 멀기 때문에 송전선이나 댐 등의 건설에 많은 비용과 기간을 필요로 한다. 특히 최근에는 댐건설로 인한 환경파괴와 자연보호의 면에서 수력발전이 전면적으로 재검토되고 있는 실정이다.However, in the case of hydropower, it is necessary to use the topography and the quantity of power that can be used for dropping. Therefore, since it is generally built in a rough mountain and far from the consumer, it requires a lot of cost and time to construct a transmission line or a dam. In particular, in recent years, hydroelectric power generation has been completely reviewed in terms of environmental destruction and nature protection due to dam construction.

화력발전은 석유, 석탄, 가스 등을 연료로 하여 보일러로 증기를 발생시킨 다음 그 압력으로 터빈 발전기를 돌려 발전하는 방식으로, 우리나라의 경우 해외에서 수입하는 연료의 수송이 편리하고 운전에 필요한 대량의 물을 얻기 쉬운 해안가에 주로 건설한다.Thermal power generation uses oil, coal, and gas as fuel to generate steam in a boiler, and then rotates a turbine generator at that pressure to generate electricity. In Korea, the transportation of fuel imported from abroad is convenient and large quantities required for operation Construct mainly on waterfront.

화력발전은 건설비가 수력발전에 비하여 싸고 건설기간도 짧으며 수요자에서 가까운 지역에 발전소를 건설하는 것이 가능한 반면에, 배기가스로 인한 공해가 심각한 문제로 제기되고 있으며, 연료의 대부분을 수입에 의존하고 있어 해외시장의 상황에 따라 제조원가의 변동이 심하다는 문제가 있다.Thermal power generation is cheaper than hydropower, construction period is shorter, and it is possible to build a power plant near the consumer, while pollution caused by exhaust gas is a serious problem, and most of the fuel depends on imports. Therefore, there is a problem that the manufacturing cost fluctuates depending on the situation of overseas market.

원자력발전은 1970년대의 석유파동을 겪으면서 석유를 대체할 수 있는 연료로서 개발되어 도입된 것으로, 우리나라의 경우에는 현재 사용하는 전력의 1/3을 원자력발전으로 얻고 있다. 그러나 원자력발전은 방사능에 대한 위험성 때문에 지역주민들의 반대에 부딪혀 증설에 어려움을 겪고 있는 실정이다.Nuclear power has been developed and introduced as a fuel that can replace oil in the 1970s, and in the case of Korea, one-third of the current electricity is used as nuclear power. However, due to the danger of radiation, nuclear power generation is facing difficulties in expanding due to opposition from local residents.

최근에는 자원의 한계와 공해 등의 문제 때문에 연료가 필요 없으며 항구적으로 사용하는 것이 가능하고, 클린에너지를 얻을 수 있는 조력이나 풍력 등을 이용하는 발전시스템에 대한 연구가 활발하게 진행되고 있다.Recently, research on power generation systems using tidal power or wind power, which requires no fuel, can be used permanently, and has clean energy due to resource limitations and pollution, is being actively conducted.

조력을 이용한 발전방법으로는 파랑을 이용하는 방법, 조수간만의 차를 이용하는 방법 등이 있다. 또 조수간만의 차를 이용하는 방법에 있어서도 밀물 때 바닷물을 저수하였다가 썰물 때 이를 배수하면서 발전하는 방법, 조수유 도로를 형성하여 밀물 썰물 때 바닷물의 흐름을 이용하여 발전하는 방법 등이 알려져 있다.The tidal power generation method includes a method using a blue wave and a method using a difference between tides. In addition, the method of using the difference between the tidal tide is known to generate the tidal water at low tide and to drain it at low tide, and to generate the tidal flow road by using the tide at the low tide.

지금까지 제안된 조력을 이용한 발전방법에 있어서는 발전효율과 건설비에 따른 경제성의 면에서 만족할 만한 성과가 없었다.So far, the proposed power generation method has not been satisfactory in terms of power generation efficiency and economic feasibility according to construction cost.

그러나 화력 발전의 한계성에 대한 근본적인 문제를 해결하고 환경공해의 유발을 해소하기 위한 방법으로는 자연력을 이용한 효과적이며 경제적인 발전방법에 대한 연구와 개발이 절실하게 필요한 실정이다.However, as a way to solve the fundamental problem of the limitation of thermal power generation and to solve the cause of environmental pollution, research and development on the effective and economic development method using natural power is urgently needed.

따라서, 파랑 에너지로 인한 선박의 상하 운동을 이용하여 자가 발전을 사용한다면 갈수록 높아져 가는 유가에 대한 부담이 적어져 비용적인 측면에서 상당한 효과가 있으며, 환경적인 측면에서도 공해를 발생시키지 않는 청정 에너지기 때문에 긍정적인 효과를 줄 수 있다.Therefore, if the self-power generation using the up and down movement of the ship due to the wave energy is less burdened with the oil price that is getting higher, there is a significant effect in terms of cost, and because it is a clean energy that does not generate pollution in the environmental aspect It can have a positive effect.

이에, 본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명의 목적은 파랑에너지로 인한 선박의 상하운동을 이용해서 선박에 고정된 자석 및 코일로부터 유도기전력을 얻도록 하여 자가발전하는 선박의 자가 발전장치를 제공하는 데 있다.Accordingly, the present invention is to solve the above problems, an object of the present invention to obtain the induced electromotive force from the magnet and coil fixed to the vessel by using the vertical movement of the vessel due to the wave energy to generate self-power of the vessel To provide a device.

상기 앵커(30)는 선박(10)의 선저에 설치된 계선기(20)와 앵커체인(32)에 의해 해저 면에 연결되어 있다.The anchor 30 is connected to the sea bottom by a mooring machine 20 and an anchor chain 32 installed on the bottom of the vessel 10.

이때, 상기 계선기(20)는 선박(10)의 선저에 설치되어 배를 매어 두는 역할을 하며, 상기 앵커(30)는 앵커체인(32)에 의해 해저 면에 고정시키는 역할을 한다. At this time, the mooring machine 20 is installed on the bottom of the vessel 10 to serve to tie the ship, the anchor 30 serves to fix the bottom surface by the anchor chain (32).

상기 선박(10)의 선저에는 고정로프(34)를 통과시키기 위한 개구부(12)가 형성되며, 상기 개구부(12)를 통과한 고정로프(34)를 이용하여 앵커(30)와 연결되는 자가발전기(40)가 설치된다. An opening 12 is formed at the bottom of the vessel 10 to allow the fixing rope 34 to pass therethrough, and is connected to the anchor 30 using the fixing rope 34 passing through the opening 12. 40 is installed.

이때, 상기 자가발전기(40) 내의 일정한 위치에 자석(50)이 고정 설치되며, 상기 고정 설치된 자석(50)의 둘레에 코일(60)이 형성되어 파랑에너지를 이용한 선체의 상하 운동에 의해 유도기전력을 발생시키게 된다.At this time, the magnet 50 is fixedly installed at a predetermined position in the self-generator 40, the coil 60 is formed around the fixed magnet 50 is installed induction electromotive force by the vertical motion of the hull using the blue energy Will be generated.

또한, 상기 자가발전기(40)에는 코일(60)에 의해 발생된 유도기전력을 전기적 에너지를 변환하여 저장하는 전기저장장치(도시안됨)가 설치되어 있다.In addition, the self-generator 40 is provided with an electrical storage device (not shown) for converting and storing the induced electromotive force generated by the coil 60 to electrical energy.
