본 발명은 태양광발전 및 풍력발전을 주동력으로 이용하는 선박에 관한 것으로서, 보다 상세하게는 선박의 동력을 일반적인 디젤엔진을 비상동력원으로 사용하고, 태양전지 및 풍력발전기를 통해 발생된 전력을 주동력원으로서 사용하는 복합적인 동력을 이용하는 선박이다.The present invention relates to a ship that uses photovoltaic and wind power as the main power, more specifically, the power of the ship using a general diesel engine as an emergency power source, the power generated through the solar cell and the wind power generator as the main power source It is a ship using a complex power used as.

종래에는 태양광발전 또는 풍력발전을 통해 발생된 전력을 선박의 주동력으로 사용한 경우는 없었다. 그리고, 단순히 태양광발전 또는 풍력발전 만을 선박의 동력으로 이용할 시에는 그 효율성이 떨어지거나, 비상시 사용이 어렵게 되는 점 등의 문제가 있다.Conventionally, power generated by solar power or wind power has not been used as the main power of a ship. In addition, when using only solar power or wind power as the power of the ship, there is a problem such that the efficiency is lowered, or difficult to use in an emergency.

따라서, 본 발명은 상술한 문제점을 해결하고자 다양한 동력원 즉, 일반적인 디젤엔진을 비상동력원 또는 보조동력원으로 사용하고 태양전지와 풍력발전기를 통해 발생된 전력을 주동력원으로 사용하여 종래의 일반적인 선박에 비해 연료비를 크게 절감할 수 있는 선박을 제공하는데 그 목적이 있다.Therefore, the present invention uses a variety of power sources, that is, a general diesel engine as an emergency power source or an auxiliary power source to solve the above problems, using the power generated by the solar cell and the wind power generator as the main power source compared to the conventional general vessels The purpose is to provide a vessel that can greatly reduce the cost.

또한, 선박 내에 사용하는 추진동력 외의 필요동력을 상기 태양광발전 및 풍력발전을 통해 발생된 전력으로 사용함으로써 연료비를 더욱 절감할 수 있으며, 보다 친환경적인 선박을 제공하는데 또 다른 목적이 있다.In addition, by using the required power other than the propulsion power used in the ship as the power generated through the photovoltaic and wind power generation can further reduce fuel costs, there is another purpose to provide a more environmentally friendly ship.

본 발명은 일반적인 디젤엔진을 비상동력으로 사용하고, 주동력으로서 태양광발전 및 풍력발전을 이용하여 발생된 전력을 사용하는 선박에 관한 것이다.The present invention relates to a ship using a general diesel engine as an emergency power, using the power generated by using photovoltaic and wind power as the main power.

즉, 태양전지 모듈 및 풍력발전기를 이용하여 발전된 전력을 축전지에 충전하고 상기 축전지에 충전된 전력을 선박 추진의 주동력으로 사용하며, 상기 축전지에 충전된 전력이 충분하지 않을 때는 디젤엔진을 가동하여 선박의 보조추진동력으로 사용하는 것이다.That is, the power generated by the solar cell module and the wind power generator is charged into the storage battery, and the power charged by the storage battery is used as the main driving force for ship propulsion. It is used as auxiliary propulsion power of ship.

이하, 첨부된 도면에 의해 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

먼저, 도 1은 본 발명의 구성예시도이고, 도 2는 본 발명의 구성블록도로서, 본 발명에 의한 태양광발전 및 풍력발전을 동력으로 이용하는 선박은 일반적인 디젤엔진(70)을 비상동력원으로 사용하고, 주동력원으로는 태양광발전 및 풍력발전을 사용하되,First, Figure 1 is an exemplary view of the configuration of the present invention, Figure 2 is a block diagram of the present invention, the ship using the solar power and wind power generation according to the present invention is a general diesel engine 70 as an emergency power source Use solar power and wind power as the main power source,

상기 태양광발전은 태양빛을 전기로 변환시키는 태양전지(10)와, 상기 태양전지(10)에서 발생된 전력을 저장하는 주축전지(30)와, 상기 주축전지(30)의 충전량을 조절해주는 전력조정기(11)와, 발전된 교류전류를 직류전류로 변환시켜주는 인버터(12)로 구성되고, 상기 풍력발전은 풍력으로 전기를 발생시키는 풍력발전기(20)와, 상기 풍력발전기(20)에서 발생된 전력을 저장하는 보조축전지(40)와, 상기 보조축전지(40)의 충전량을 조절해주는 전력조정기(21)와, 발전된 교류전류를 직류전류로 변환시켜주는 인버터(22)로 구성되며,The photovoltaic power generation is a solar cell 10 for converting sunlight into electricity, a main battery 30 for storing the power generated by the solar cell 10, and controls the amount of charge of the main battery 30 It consists of a power regulator 11, an inverter 12 for converting the generated alternating current into a direct current, the wind power generation is a wind generator 20 for generating electricity by wind power, and the wind generator 20 is generated It consists of an auxiliary storage battery 40 for storing the electric power, a power regulator 21 for adjusting the amount of charge of the auxiliary battery 40, and an inverter 22 for converting the generated alternating current into direct current,

상기 주축전지(30) 및 보조축전지(40)의 전력으로 가동되며 추진샤프트(도시하지 않음)와 동력전달수단으로 연결되어 있는 DC모터(도시하지 않음)로 구성되어 있다.It is composed of a DC motor (not shown) that is operated by the power of the main battery 30 and the auxiliary storage battery 40 and is connected to the propulsion shaft (not shown) and the power transmission means.

먼저, 주엔진은 일반적인 디젤엔진(70)을 사용하며 이는 현재 많은 선박에 사용되고 있으므로 상세한 설명은 생략한다.First, the main engine uses a general diesel engine 70, which is currently used in many ships, so detailed description thereof will be omitted.

그리고, 태양전지(10)는 비, 눈 또는 구름 등에 의해 햇빛이 비치지 않는 날이나 해가 진 뒤에는 전기가 발생하지 않으므로 일사량의 강도에 따라 균일하지 않은 전기가 발생한다. 따라서, 일반적인 태양광 발전시스템은 수요자에게 항상 필요한 전기를 공급하기 위하여 모듈을 직, 병렬로 연결한 태양전지 어레이와 전력저장 용 축전지, 전력조정기 및 인버터 등의 주변장치가 필요하다.In addition, since the solar cell 10 does not generate electricity on a day when the sun does not shine due to rain, snow, clouds, or the like, the electricity is not uniform according to the intensity of the solar radiation. Therefore, a general photovoltaic power generation system requires a solar cell array in which modules are connected directly and in parallel, and peripheral devices such as a power storage battery, a power regulator, and an inverter in order to supply electricity necessary to a consumer.

또한, 풍력발전기(20)는 풍력을 이용하여 블레이드(날개)를 돌려서 유도전기를 발생시키고 이 전기를 충전시킨 축전지를 선박의 보조동력으로 사용하는데, 이는 해상에서는 많은 바람이 부는 특징으로 인해 많은 전력을 얻을 수 있으며, 선박의 크기나 필요한 전력량에 따라 풍력발전기(20)의 크기나 수에 있어서 다양한 구성 및 설치가 가능하다.In addition, the wind power generator 20 generates induction electricity by rotating blades (wings) using wind, and uses the battery charged with the electricity as auxiliary power of the ship, which is a lot of power due to the windy characteristics at sea. It is possible to obtain, depending on the size of the ship or the amount of power required can be various configurations and installation in the size or number of the wind turbine (20).

상기 태양전지(10)는 전지의 효율과 제품의 정도에 따라 출력에 많은 차이가 있으나, 보통 3 Ton 선박의 경우 세로 1.2m, 가로 0.5m 인 태양전지판이 4장 이상이 필요하며, 주축전지(30) 역시 12V 용량 4개 이상이 필요하다. 상기 주축전지(30)를 완전히 충전하는데 소요되는 시간은 날씨가 맑은 날 10시간 정도가 소요되며, 상기 주축전지(30)로서만 4~5시간 운행이 가능하다. 기존 디젤엔진(70)을 사용하여 8노트 정도의 속도가 나오는 선박은 상기 주축전지(30)로서 프로펠러(60)를 돌리게 되면 11노트 이상의 속도로 운행이 가능하다.The solar cell 10 has a large difference in output depending on the efficiency of the battery and the degree of the product, but in the case of a 3 Ton vessel, four or more solar panels having a length of 1.2 m and a width of 0.5 m are required. 30) 4 or more 12V capacity is also required. The time required to fully charge the main battery 30 takes about 10 hours on a clear day, and can operate for 4 to 5 hours only as the main battery 30. When the speed of about 8 knots comes out using the existing diesel engine 70, the ship can be operated at a speed of 11 knots or more by turning the propeller 60 as the main battery 30.

상기 풍력발전기(20)에서 발생되는 전력은 태양전지(10)에서 발생된 전력보다 약할 경우가 많으므로 보조축전지(40) 쪽으로 충전시키며, 상기 보조축전지(40)에 저장된 전력으로서 주축전지(30)에 충전을 해주거나 선박내 전기용품(90)의 전원으로 사용할 수 있다. Since the power generated by the wind power generator 20 is often weaker than the power generated by the solar cell 10, the power is charged toward the auxiliary storage battery 40, and the main storage battery 30 is stored as power stored in the auxiliary storage battery 40. It can be used as a power source for charging or in ship electrical appliances (90).

여기서, 주축전지(30)와 보조축전지(40) 사이에는 주축전지(30)의 전류가 보조축전지(40) 쪽으로 흐르지 못하도록 역류방지회로(80)를 구성해두는 것이 바람직하다.Here, it is preferable to configure the backflow prevention circuit 80 between the main battery 30 and the auxiliary battery 40 so that the current of the main battery 30 does not flow toward the auxiliary battery 40.

즉, 본 발명은 먼저 1차적으로 태양전지(10) 및 풍력발전기(20)에서 발생된 전력으로 선박(100)의 추진주동력으로 이용하며, 이를 보조해주기 위하여 디젤엔진(70)을 이용하여 선박(100)의 비상동력 또는 보조동력으로 사용한다.That is, the present invention primarily uses the power generated from the solar cell 10 and the wind power generator 20 as a driving force of the ship 100, and uses the diesel engine 70 to assist this. Use as emergency power or auxiliary power of (100).

상술한 바와 같이, 본 발명에 의한 태양광발전 및 풍력발전을 동력으로 이용하는 선박은 선박의 주동력을 기름이 필요하지 않은 태양광발전 및 풍력발전을 이용하여 반영구적으로 사용이 가능하므로 막대한 연료비를 절감할 수 있는 효과가 있다.As described above, the vessel using the photovoltaic power generation and wind power generation according to the present invention can be used semi-permanently using the main power of the vessel using the photovoltaic power generation and wind power generation that does not require oil, thereby reducing enormous fuel costs. It can work.

또한, 디젤엔진의 사용으로 발생할 수 있는 배기가스배출, NOx 발생문제, 디젤흑연(PM)배출, 해양오염 등 갈수록 심해지는 환경오염을 줄일 수 있는 효과가 있다.In addition, there is an effect that can reduce the environmental pollution, such as exhaust gas emissions, NOx generation problems, diesel graphite (PM) emissions, marine pollution that can occur due to the use of a diesel engine.
