Description

소수력발전용 수차{Multy Screw Type Hydraulic Turbine}Minority Power Generation Aberration {Multy Screw Type Hydraulic Turbine}

소수력발전을 함에 있어서 계곡, 강물, 바다는 좌우상하 난류 형태로 진행하는 풍부한 수량과 유속(流速)을 가지고 있다. 이러한 풍부한 수력 에너지를 이용하는 방법으로, 평판 터빈 날개 수차나 프로펠러 수차를 사용하여 수력에 의한 소수력발전을 하였으나, 평판 터빈 날개 수차는 중심축 상단 이상의 구조물을 설치하여야 하며, 보 형태의 토목 구조물을 설치하므로, 전력생산량에 비례하여 고비용의 투자, 환경훼손을 감수하여야, 목적을 이룰 수 있다. 프로펠러 수차는 수중에 수차용 지지 구조물을 설치하여야 하며, 구조물을 고정(固定) 함으로서 좌우상하로 흐르는 난류의 유입 방향 이탈과 중심축에 의하여 역류가 발생 되어 역류부하로 인한 충격력의 효율이 떨어지고, 지지대 구조물과 중심축에 부유물이 집적(集積) 되므로 서, 발전 효율감소의 원인이 되며, 구조물 설치에 의한 수중 환경훼손 등의 단점이 있다. 아울러 바다의 해류는 내륙보다 풍부한 수량과 강한 유속(流速) 을 가지고 있음에 도 불구하고, 종래의 기술로서는 소수력발전의 소기의 목적을 이룰 수 없었다. 계곡 강 바다의 풍부한 자연에너지를 이용한 친환경적이며, 경제적인 수력발전 기술이 절실히 요구되고 있는 실정이다In hydropower generation, valleys, rivers, and seas have abundant yields and flow rates in the form of turbulence. As a method of using such abundant hydraulic energy, hydropower generation by hydroelectric power is carried out using flat turbine blade aberration or propeller aberration, but flat turbine blade aberration should be installed above the central axis, and it will install beam type civil structure. In order to achieve this goal, investments incurred at high cost and environmental damage in proportion to power generation can be achieved. The propeller aberration should be equipped with a support structure for the aberration in water, and by fixing the structure, backflow is generated by the inflow direction of the turbulent flow in the left and right and up and down and the central axis, which reduces the efficiency of the impact force due to the backflow load. Due to the accumulation of suspended solids in the structure and the central axis, it causes a decrease in power generation efficiency, and there are disadvantages such as damage to the underwater environment due to the installation of the structure. In addition, even though ocean currents have abundant yields and stronger flow rates than inland, conventional techniques could not achieve the intended purpose of hydroelectric power generation. Eco-friendly and economical hydropower technology using the abundant natural energy of the valley river is urgently needed.

종래 발명된 소수력발전용 수차는 회전되는 운동에너지를 수차의 중심축에 의하여 발전기를 회전시켜 발전하였다. 중심축이 회전되는 수차는 인공적으로 구조물을 설치하여야 만, 수차를 구동할 수 있다. 하천이나 바다를 이용한, 소수력발전에서 종래의 방법으로는, 소수력발전 목적을 이루는 하나의 방법 일수는 있으나. 소수력발전의 경제성에 비례하여 투자비용, 자연 훼손 등의 이유로 활성 화 되지 못하였다. 본 발명은 수차 중심축을 제거하여 인공 시설물의 설치가 필요 없이, 하천이나 바다의 물의 흐름에 따라 상하 좌우로 움직이도록 하면서, 하천이나 바다의 수력에너지를 이용하여, 경제적이고 친환경적인 소수력발전의 목적을 이루고자 하는 발명이다.       The hydropower generating aberration of the related art was developed by rotating a generator by the central axis of the aberration kinetic energy. The aberration in which the central axis is rotated must be artificially installed to drive the aberration. Conventional methods in hydroelectric power generation using rivers or the sea may be one way of achieving hydroelectric power generation goals. In proportion to the economics of small hydro power generation, it was not activated due to investment costs and natural damage. The present invention eliminates the central axis of the aberration without the need for installation of artificial facilities, while moving up and down and left and right according to the flow of the water of the river or the sea, using the hydro energy of the river or the sea, the purpose of economical and environmentally friendly hydropower generation It is an invention to be achieved.
