[4] 그리고,태양에너지를이용한태양발전은국내등록특허제 -1603782호에 개시된바와같이,화력이나원자력같은기존발전설비와달리연료비가 소요되지않으며,소음과공해가발생하지않는장점이있고,태양발전은대규모 발전설비를필요로하지않으며,소규모발전이가능하기때문에,가정용으로도 설치하여사용할수있는장점이 있다.
[5] 이러한태양에너지를이용하는발전에는태양광을전기에너지로변환하는 태양광발전시스템은반도체로된태양전지판（솔라셀）에태양광이조사되면, 광（光）기전력현상에의해전기가발생하게되고,이와같이
태양전지판（솔라셀）에서발생하는전기를배터리에충전시키며,충전된전기는 소정의개소에공급하여사용한다.
[6] 그러나,이와같은태양광발전은태양광의위치에따라전력발생량이
좌우되며,태양광이없는날씨에는발전이불가능하여상시부하에대한 안정적인전력공급원으로써전력공급이불가능한단점이있다. 2020/175840 1»（：1^1{2020/002179

[24] 그리고,아래실시예에서의선택적인용어는하나의구성요소를다른
구성요소로부터구별하기위해사용되는것으로서,구성요소가상기용어들에 의해제한되는것은아니다.
[25] 이에,본발명을설명함에 있어서,본발명의요지를불필요하게흐릴수있는 관련된공지기술에 대한상세한설명은생략한다.
[26] 첨부도면도 1내지도 3은본발명에 따른풍력복합수상지주교량형식
태양광발전시스템을도시한도면들이다.
[27] 본발명에 따른태양광발전시스템은도 1에도시된바와같이 ,태양광 (태양의 빛에너지 )을전기에너지로변환시키는태양광발전모듈 (100)과,풍력을 전기에너지로변환시키는풍력 발전모듈 (200)(200幻을포함한다.
[28] 이러한태양광발전시스템은햇빛이 잘들고바람이 잘통하는곳에설치됨이 바람직하고,일례로물이 있는저수지나수로등에설치될수있다.
[29] 태양광발전모듈 (100)은도 1및도 2에도시된바와같이，지면에수직하게 세워져 설치되는다수의지주 ( 0)와,다수의지주 ( 0)위에 태양을향해 경사지게구비되어 태양의 빛에너지를전기에너지로변환시키는 2020/175840 1»（：1^1{2020/002179 태양전지판 (120)을포함한다.
[3이 다수의지주 ( 0)는태양전지판 (120)하면의전,후부에각각구비되되,전방의 지주또는후방의지주중어느한쪽의지주가다른쪽의지주보다낮은높이로 구비되어,태양전지판 (120)의경사도를확보할수있게된다.
[31] 이러한지주 ( 0)는도면으로도시되지는않았지만,태양의위치에따라
지주 ( 0)의높이를달리조절할수있도록구성할수도있고,이를위해태양의 위치에따라전방및후방의지주 (110)높이를가변시킬수있는구동수단과, 태양의위치를감지하여구동수단을구동시키는조도센서등이더구비될수 있다.
[32] 특히,구동수단은전방의양지주 ( 0)와후방의양지주 ( 0)를각각높이
조절하되,이러한구동수단은각지주 (110)마다독립되게구비될수있고,또는 전방의지주 ( 0)와후방의지주 ( 0)를각각작동시킬수있도록복수개로 구비될수있되,이경우는전,후부의양구동수단은컨트롤러에의해서동시에 작동되도록제어됨이바람직하다.
[33] 따라서,태양의위치에따라전방및후방의지주 ( 0)높이를조절함으로써 지주 ( 0)상의태양전지판 (120)이항상태양과대향되게구비되어 ,태양 에너지를최대한받아발전할수있게된다.
[34] 도면에서는도시되지않지만지주들사이에수평가교가더욱구비될수있고, 상기수평가교에는태양광및풍력발전시설에요구되는다양한설비,예컨대 배전반,배터리,변압기등의장치가장착될수있다.
[35] 또한,상기와같은지주 ( 0)는하천주변이나해변주변또는호수주변에
설치되는것으로,하천,해변,호수등지에서교량지주를설치하고,교량지주 위에후술될태양광발전모듈 (100)및풍력발전모듈 (200)(200幻을구성한다.
[36] 그리고,상기와같은태양전지판 (120)은태양의빛에너지를집광하여
전기에너지로변환시키는솔라셀로구비될수있다.
[37] 여기서,미설명부호” 121”은프레임으로서,후술될풍력발전모듈 (200)(200^이 탈,부착가능하게결합고정되는부분이다.
[38] 풍력발전모듈 (200)(200幻은풍력을전기에너지로변환시키는모듈로서도 1 및도 2에도시된바와같이,태양전지판 (120)의프레임 (121)에탈,부착가능하게 구비되어바람이유입되는풍입구 (21 1)(21 1幻를갖는드럼 (210)(210幻과, 드럼 (210)(210幻내에회전가능하게구비되는블레이드 (220)와,
드럼 (210)(210幻에구비되어바람에의한블레이드 (220)의회전력을전달받아 전기에너지를발생시키는발전기 (250)를포함한다.
[39] 특히 ,상기와같은풍력발전모듈 (200)(200幻은도 3에서와같이 ,
태양전지판 (120)의상단부와하단부에각각구비될수있고,태양전지판 (120)의 상단부에구비된상부풍력발전모듈 (200)과태양전지판 (120)의하단부에 구비된하부풍력발전모듈 (200幻은드럼 (210)(210幻의위치만다를뿐,나머지 구성은양자모두동일하게구성된다. 2020/175840 1»（：1^1{2020/002179
[4이 이에,먼저상부풍력발전모듈 (200)에 대해설명하면,드럼 (210)이
태양전지판 (120)의상단부에고정되게구비되고,드럼 (210)의풍입구 (211)는 태양전지판 (120)의상면을타고올라오는바람이유입될수있도록
태양전지판 (120)의상단부상면에서 태양전지판 (120)의하단부를향해 개구되게 구비된다.
[41] 이때,드럼 (210)은태양전지판 (120)의상면과후술될풍향유도판 (230)의하면 사이에구비됨이바람직하고,이와같이구비된드럼 ( 0)은이의풍입구 (211)를 통해풍력효율을극대화할수있게된다.
[42] 그리고,이와같은풍입구 (211)는드럼 (210)의길이 방향으로구비되되,이런 풍입구 (211)의길이는태양전지판 (120)의좌우폭에 대응한길이로구비됨이 바람직하다.
[43] 이로써,태양전지판 (120)의상면을타고상단부로불어오는바람은
드럼 (210)의풍입구 (211)를통해모두유입되어드럼 (210)내의블레이드 (220)를 회전시키게된다.
[44] 또한,드럼 (210)에는드럼 (210)내로유입되어블레이드 (220)를회전시킨
바람이 배출되는통기구 (212)가형성될수있으나,이러한통기구 (212)는 블레이드 (220)의회전 (즉,회전수또는회전력)을저하시키지 않는영역내에서 구비되는것이바람직하다.
[45] 즉,통기구 (212)를드럼 (210)의하측에구비하여드럼 (210)의풍입구 (211)로 유입된바람이드럼 ( 0)의내주면을따라유동되면서블레이드 (220)를 회전시킨후통기구 (212)로배출되도록구성할수도있으나,본실시예에서는 통기구 (212)를드럼 (210)의후면에구비하여드럼 (210)의풍입구 (211)로유입된 바람이블레이드 (220)를회전시키면서통기구 (212)를통해그대로드럼 (210)을 통과하여 배출되도록구성하였다.이와같이드럼 (210)의후면에통기구 (212)가 구비됨에 따라바람은풍향방향그대로드럼 ( 0)을통과하여 배출됨으로써 바람에 의한드럼 ( 0)에서의소음을저감시킬수있는장점이 있다.
[46] 게다가,상기와같이 바람에의한소음을최대한방지하기위한목적으로, 후술될풍향유도판 (230)의 내측면에는소음방지수단이 더구비될수있고,이에 대해서는하기의풍향유도판 (230)에서자세히 설명하기로한다.
[47] 그리고,블레이드 (220)는드럼 (210)내부의중심을길이 방향으로관통하여 축설된회전축 (221)상에다수개로구비되고,회전축 (221)은그양측단부가 드럼 ( 0)의 양측면에 베어링을매개로회전자재하게구비됨이 바람직하다.
[48] 이와같은블레이드 (220)는풍입구 (211)로유입되는바람의풍력이
블레이드 (220)의 전면에 최대로집중되어 작용할수있도록원호형상으로 형성되되,이러한블레이드 (220)의 원호는풍입구 (211)와대향되는전면은 후방으로함몰되고반대편의후면은볼록하게돌출되는형상으로구비됨이 바람직하다.
[49] 또한,풍입구 (211)상부의드럼 (210)에는태양전지판 (120)을타고불어오는 2020/175840 1»（：1^1{2020/002179 바람을드럼 (210)의풍입구 (211)로가이드하는풍향유도판 (230)이구비된다.
[5이 이러한풍향유도판 (230)은드럼 (210)의상부에서태양전지판 (120)측으로
돌출되게구비되되,풍향유도판 (230)은태양전지판 (120)의경사각도와같거나 이보다큰각도 (태양전지판 (120)의상방향으로더벌어진각도로서,이하본 실시예에서는이경우를예시하여설명한다)로경사지게구비되어 ,
태양전지판 (120)위에작용하는바람을최대한드럼 (210)의풍입구 (211)로 유입되도록한다.
[51] 이때,풍향유도판 (230)의내측면에는바람에의한소음의발생을방지하기 위한소음방지수단이구비되고,이소음방지수단은풍향유도판 (230)의내측면에 복수의인조잔디밴드 (231)가풍향과동일방향으로설치되어구비된다.
[52] 이러한복수의인조잔디밴드 (231)는밴드형태로이루어진다수개로서, 풍향유도판 (230)의내측면즉태양전지판 (120)과마주하는풍향유도판 (230)의 하면에일정간격마다이격되게구비되어,태양전지판 (120)과풍향유도판 (230) 사이로유입되는바람이인조잔디밴드 (231)의잔디와접하게됨으로써바람과 풍향유도판 (230)의직접적인충돌및그에따른풍향유도판 (230)의진동이 방지되어소음발생이방지된다.
[53] 한편,상기와같은풍향유도판 (230)은태양전지판 (120)측으로돌출되게
구비됨에따라풍향유도판 (230)의일부가태양전지판 (120)의집광효율을 저하시킬수도있으나,풍향유도판 (230)은태양광이투과할수있는투명한 재질로형성됨으로써태양전지판 (120)의집광효율을최대한저해하지않도록 구비된다.
[54] 이와같은태양전지판 (120)은풍향유도판 (230)에의해그전면이덮혀가려질 수있거나또는일부분만덮혀가려질수도있다.
[55] 게다가,상기와같이투명한풍향유도판 (230)에의해가려지는
태양전지판 (120)은과도한직사광선에의한태양열로부터태양전지판 (120)에 구비되는태양전지모듈즉솔라셀이보호되어태양전지판 (120)의기능저하를 사전에방지할수있게된다.
[56] 그리고,드럼 (210)또는태양전지판 (120)에는발전기 (250)가구비되고,
발전기 (250)는블레이드 (220)의회전축 (221)과연결되어풍력에의해회전되는 블레이드 (220)와회전축 (221)으로부터회전력을얻게되어전기에너지를 발생시키게된다.
[57] 이때,발전기 (250)와회전축 (221)사이에는발전기 (250)의발전효율을높이기 위한증속비를갖는기어박스 (240)가구비될수있고,이기어박스 (240)는풍향이 좋은곳에서는감속비를갖도록구비되어발전기 (250)의과부하를방지할수도 있다.
[58] 또한,하부풍력발전모듈 (200幻은전술한바와같이,상부풍력
발전모듈 (200)과동일한구성및구조로이루어져있으므로이에대한반복 설명은생략하되,상부풍력발전모듈 (200)과차이가있는드럼 ( 0幻에 2020/175840 1»（：1^1{2020/002179 대해서만자세히설명하기로한다.
[59] 하부풍력 발전모듈 (200a)은도 3에도시된바와같이 ,태양전지판 (120)의
하단부에드럼 (210a)이구비되고,드럼 (210a)에는태양전지판 (120)의하면을 타고내려오는바람이유입될수있도록태양전지판 (120)의하단부하면에서 태양전지판 (120)의상단부를향해개구된풍입구 (21 la)가구비되고,
풍입구 (211a)반대편의드럼 (210a)에는개구된통기구 (212a)가구비된다.
[6이 이와같은풍입구 (21 la)는상부풍력 발전모듈 (200)과마찬가지로,
드럼 (2Wa)에서 태양전지판 (120)의좌우폭에 대응한길이로형성됨으로써, 태양전지판 (120)의하면을타고하단부로불어오는바람은드럼 (210a)의 풍입구 (211a)로모두유입되어드럼 (2Wa)내부의블레이드 (220)를회전시키면서 통기구 (212a)를통해그대로드럼 (210a)을통과하여 배출되므로바람에 의한 드럼 (2Wa)에서의소음을저감시킬수있게된다.
[61] 그리고,상기와같은풍입구 (21 la)하부의드럼 (210a)에는태양전지판 (120)을 타고아래로불어오는바람을드럼 (2Wa)의풍입구 (21 la)로가이드하는 풍향유도판 (230a)이구비되되,이풍향유도판 (230a)은상부풍력
발전모듈 (200)의풍향유도판 (230)과방향만반대일뿐인조잔디 밴드 (231a)가 구비되는등의나머지구성은동일하므로이에 대한자세한설명은상부풍력 발전모듈 (200)의풍향유도판 (230)에 대한설명으로갈음하기로한다.
[62] 한편,상기와같은하부풍력 발전모듈 (200a)에는별도의발전기 (250)가
구비되고,이 발전기 (250)는전술한상부풍력발전모듈 (200)과마찬가지로 블레이드 (220)의회전축 (221)과연결되어블레이드 (220)에의한회전력을받아 발전되어 전기에너지를발생시키게된다.
[63] 물론,발전기 (250)와회전축 (221)사이에는증속비또는감속비를갖는
기어박스 (240)가더구비될수있다.
[64] 따라서 ,이상과같은본발명의풍력복합수상지주교량형식 태양광
발전시스템은태양광발전모듈 (100)에구성된태양전지판 (120)이 태양의 빛 에너지를받아전기에너지를발생시키고,발생된전기에너지는에너지 저장 장치 (ESS : Energy Storage System) (미도시)에 저장되었다가필요시용도에맞게 사용할수있게된다.
[65] 그리고,상기와같은태양광의발전시 태양전지판 (120)을타고부는바람은 태양전지판 (120)의상단부와하단부에각각구비된풍력 발전모듈 (200)(200a)의 드럼 (2W)(210a)내로유입되어블레이드 (220)를회전시키게되고,이의회전력은 발전기 (250)로전달되어 발전기 (250)에서 전기를발생시키게되며 ,이에 생성된 전기에너지는에너지 저장장치에 저장된다.
[66] 이로써，본발명은태양광과풍력을이용한상호발전에의해 전기에너지를 지속적으로생성하여 저장할수있다.
[67] 이상본발명을구체적인실시예를통하여상세히설명하였으나,이는본
발명을구체적으로설명하기 위한것으로,본발명은이에 한정되지 않으며,본 2020/175840 1»（：1^1{2020/002179 발명의기술적사상내에서당분야의통상의지식을가진자에의해그 변형이나개량이가능함이명백하다.
