Description
본 발명은 소수력 발전장치용 수차 회전력 증강장치에 관한 것으로, 보다 상세하게는 수로에 설치되어 수차의 하부로 흐르는 물에 의해 발전이 가능한 소수력 발전장치용 수차에 수로의 높이와 수압을 이용하여 수차의 상부로 부터 다시 물을 낙하시켜줌으로써 보다 더 효율적인 소수력발전을 가능하게 하기 위한 장치에 관한 것이다.
The present invention relates to an aberration torque augmentation device for hydrophobic power generation apparatus, and more particularly, it is installed in a waterway by using the height of the waterway and the water pressure in the aberration for the hydrophobic power generation apparatus that can be generated by water flowing under the aberration. The present invention relates to a device for enabling more efficient hydropower generation by dropping water from the top again.
일반적으로 소수력발전은 인근 소하천의 유수를 이용하여 전력을 생산하는 방법으로, 대개 산간이나 농촌지역과 같이 대규모 발전 등이 곤란한 지역에서의 전력공급을 위해 주로 사용된다.In general, small hydro power generation is a method of generating electricity by using water from nearby small rivers, and is mainly used for supplying power in areas where large-scale power generation is difficult, such as mountains or rural areas.
상기 소수력 발전방식은 하천경사가 급한 상류지역에 효율적인 수로식(Run of rivertype)과, 하천경사가 적은 중하류의 유량이 풍부한 지역에 효율적인 댐식(Storage type), 그리고 수로식과 댐식의 혼합방식으로 굴곡이 심한 하천지역에 적합한 터널식(tunnel type) 등이 있으며, 발전용 수차로는 충격형 수차와 반동형 수차가 있다.The small hydro power generation system has an efficient run of rivertype in the upstream area where the river slope is steep, an efficient dam type in an area rich in flow in the middle and downstream streams where the river slope is low, and a hybrid of the channel and dam type. Tunnel type suitable for severe river area, etc. There are shock aberration and reaction aberration for the power generation aberration.
특히 수로식(Run of rivertype)은 농수로 등에 수차를 설치하여 발전을 하는 방식으로 종래에는 특허출원 제10-2012-0127706호와 같이 수로에 설치된 수차를 수로의 하부로 흐르는 물로 회전시키거나, 특허출원 제10-2009-0054045호와 같이 낙차를 이용하여 수차를 회전시키는 방식 둘 중의 하나의 방법만을 사용하는 구조이다.
In particular, the Run of rivertype is a method of generating power by installing aberrations in agricultural waterways and the like. In the related art, a water wheel installed in a waterway is rotated with water flowing under a waterway as in Patent Application No. 10-2012-0127706, or a patent application is made. As in 10-2009-0054045, it is a structure using only one of two methods of rotating aberrations using a drop.
상기와 같이 낙차만 이용하거나 수로를 따라 흐르는 수압만을 이용하여 발전을 하는 것은 효율이 매우 떨어지는 구조로 농수로와 같이 낙차가 크지 못한 지형에서는 효율적인 발전이 곤란한 구조이다.As described above, the power generation using only the drop or only the water pressure flowing along the waterway is a very inefficient structure, and in the terrain where the drop is not large, such as a farm, the efficient power generation is difficult.

이처럼 비교적 설치장소에 제약을 덜 받으며 지속적인 전력생산이 가능한 소수력 발전방법이 농촌 및 산간지역과 같이 소규모의 전력이 요구되는 곳에 매우 요긴한 것으로 알려지면서 대한민국 공개특허공보 제1991-0001971호 "하천 유수를 이용해 전력을 생산하는 소수력 발전장치" 및 대한민국 공고실용신안공보 제1993-8538호 "댐의 수문설비를 이용한 소수력 발전장치" 등이 출원된 바 있다.
As such, it is known that a small hydro power generation method that is relatively restricted to the installation site and is capable of generating continuous power is very useful where small electric power is required, such as rural areas and mountainous areas, and is disclosed in Korean Patent Publication No. 1991-0001971. A small hydro power generating device using electric power to generate electricity "and Korean Utility Model Publication No. 1993-8538," A small hydro power generating device using a hydrological facility of a dam "have been filed.
본 발명은 상기와 같은 종래 소수력 발전장치의 단점을 해결하기 위해 안출된 것으로, 본 발명은 수로에 흐르는 물의 수압에 의해 회전하면서 발전하도록 하는 수차가 설치된 하우징 상부에 배수구를 구비하는 관연결구를 형성하되, 상기 관연결구에는 물공급관이 연결되도록 하고 상기 물공급관은 하우징이 설치된 수로의 높이보다 더 높은 곳에 위치한 수로 전방에 형성되는 물흡입구에 연결되도록 함으로써 상기 물흡입구에 의해 유도된 물이 물공급관과 관연결구를 통해 수차의 상부로 부터 낙하되도록 함으로써 수차의 회전력을 높여 발전효율을 높일 수 있도록 함을 특징으로 한다.
The present invention has been made to solve the disadvantages of the conventional hydrophobic power generation apparatus as described above, the present invention is to form a pipe connector having a drain on the upper portion of the housing is installed aberration to generate power while rotating by the water pressure of the water flowing in the water channel The water pipe is connected to the water supply pipe and the water supply pipe is connected to the water inlet formed in front of the water channel located in a position higher than the height of the water channel in which the housing is installed, so that the water induced by the water inlet is connected to the water supply pipe and the pipe. By dropping from the top of the aberration through the connector is characterized in that to increase the rotational force of the aberration to increase the power generation efficiency.
이처럼 본 발명의 효과로는 수로를 따라 흐르는 물의 수압과 수차에 낙하되는 물의 충격과 무게에 의해 수차가 회전되도록 함으로써 발전효율을 높일 수 있는 것이다.Thus, the effect of the present invention is to increase the power generation efficiency by rotating the aberration by the water pressure and the impact and weight of the water falling on the aberration flowing along the waterway.
또한 본 발명은 물흡입구의 위치를 하우징이 설치된 수로의 높이보다 더 높은 곳에 설치함으로써 대기압과 수압을 이용하여 물의 낙하를 가능하게 하였고, 이로 인해 별도의 동력과 시설을 필요로 하지 않게 되어 경제적인 소수력 발전이 가능한 매우 유용한 발명이다.
In addition, the present invention by installing the position of the water suction port higher than the height of the water channel in which the housing is installed to enable the water drop by using atmospheric pressure and water pressure, thereby eliminating the need for a separate power and facilities economical hydropower It is a very useful invention that can be developed.

본 발명은 수로에 안쪽에 설치되는 하우징(110)과 상기 하우징(110)에 의해 회전축이 지지되어 회전가능한 다수개의 날개(111a)를 구비하는 수차로 이루어지되, 상기 하우징(110) 상부에 배수구(121)를 구비하는 관연결구(120)를 형성하되, 상기 배수구(121)는 수차 날개(111a)가 수평상태일 때 끝단부와 수직선상의 상부에 위치하도록 하고, 관연결구(120)에는 물공급관(130)의 일측이 연결되도록 하며 상기 물공급관(130)의 타측은 물흡입구에 연결되도록 하되 상기 물흡입구(140)는 하우징(110)이 설치된 수로의 높이보다 더 높은 곳에 위치한 수로 전방에 설치되도록 구성된다.The present invention is made of aberration having a plurality of blades (111a) rotatable by the
따라서 상기 물흡입구(140)에 의해 유도된 물은 물공급관(130)과 관연결구(120)를 통해 수차 날개(111a)의 상부로 부터 낙하되도록 하여 결국 상기 수차는 수로를 따라 흐르는 물의 수압과 낙하되는 물의 충격과 무게에 의해 회전하게 됨으로써 발전효율을 극대화할 수 있게 된다.Therefore, the water induced by the
상기 물흡입구(140)는 수차에 낙하시키기 위한 물을 물공급관(130)으로 유도하기 위한 수단으로, 입구가 사각형상을 가지며, 후방으로 갈수록 직경이 좁아지는 테이퍼형상으로 이루어진다.The water suction opening 140 is a means for guiding water for dropping into the aberration to the
또한 상기 물흡입구(140)는 하우징(110)이 설치된 수로의 높이보다 더 높은 곳에 설치되는데, 관연결구(120)의 높이보다 더 높은 위치에 설치됨이 가장 바람직하다. 즉 상기 물흡입구(140)의 위치가 높을수록 대기압이 커져 별도의 동력을 가하지 않고도 물을 수차 위에 낙하시키기 더욱 용이하기 때문이다.In addition, the
물론 상기 물흡입구(140)의 위치가 관연결구(120)의 높이보다 조금 낮다 하여도 상기 물흡입구(140)는 테이퍼형상이어서 수로를 흐르는 물의 수압이 작용하게 되고 상기 수압으로 인해 상기 물흡입구(140)가 관연결구(120)의 높이보다 조금 더 낮은 곳에 위치하고 있다하더라도 물의 낙차는 가능하게 된다.Of course, even if the position of the
본 발명에 사용되는 수차는 날개(111a)가 호(弧) 형상을 갖는 곡면판으로 이루어지고 상기 곡면판의 가장자리와 내측을 보강대에 의해 지탱함으로써 수차의 날개(111a)가 지면과 수평이 되었을 때 물을 받을 수 있는 용기의 형태가 된다.The aberration used in the present invention is when the blade 111a is made of a curved plate having an arc shape and the blade 111a of the aberration is horizontal to the ground by supporting the edge and the inner side of the curved plate with a reinforcing rod. It is in the form of a container that can receive water.
따라서 관연결구(120)의 배수구(121)로 부터 낙하된 물은 수차의 날개(111a)에 충격을 가하지만 또한 날개(111a)에 채워지게 되어 충격과 동시에 무게를 수차의 날개(111a)에 가하게 되고 이로 인해 자연스럽게 수차의 회전을 유도할 수 있게 되는 것이다.
Therefore, the water dropped from the
상기한 바와 같은 구성을 갖는 본 발명이 비록 한정된 실시예에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 청구범위의 균등범위 내에서 다양한 수정 및 변형이 가능하다 할 것이다.
