The non-powered eccentric apparatus for the reduction of the thermal stratification in lake with inducing surface water flow into vertical downflow

The present invention provides a non-powered eccentric apparatus for reducing thermal stratification in a lake by using a drift current descent guidance device. The non-powered eccentric apparatus comprises: the drift current descent guidance device which is formed by connecting, in an arched shape, a plurality of drift current descent guidance units converting, into a vertical flow, kinetic energy moving horizontally on the surface of a lake while floating on the surface of the lake; a fixing anchor which is spaced a distance away from the inside of the current descent guidance device having the arched shape and is erected in a vertical line so that a lower side thereof is fixed to the bottom of the lake; and a plurality of connecting lines of which sides are connected to an upper side of the fixing anchor, the other sides opposite thereto are connected to the plurality of drift current descent guidance units, respectively, and the length is relatively great than that on sides of the drift current descent guidance units from the sides toward the other side thereof so that the arc center of the drift current descent guidance device is eccentric. Even with low wind speeds and changes in wind direction of the lake, the eccentricity of the drift current descent guidance device and the function of a windbreak installed at the top enable the drift current descent guidance device to rotate in only one direction using the fixing anchor as the shaft, thereby solving the problem that the connecting lines connecting the drift current descent guidance device and the fixing anchor are twisted together, and can effectively guide a vertical flow facing deep water to form a wide recirculating flow in two areas with the drift current descent guidance device as the border, at upwind (upper wind) and downwind (lower wind) locations, which are the inside of the arc of the drift current descent guidance device, thereby preventing thermal stratification. 본 발명은 호소의 수면에 부유하면서, 호소 표면의 수평방향으로 유동하는 운동에너지를 수직 방향으로 유동하도록 전환하는 취송류 하강유도유닛 복수 개가 호(弧) 형상으로 연결되어 이루어진 취송류 하강유도장치; 호(弧) 형상을 이루는 취송류 하강유도장치의 호 내측과 일정 거리를 이격되면서, 수직선상으로 세워져 하측이 호소 바닥에 고정되는 고정앵커; 및 상기 고정앵커의 상측과 일측단이 연결되고, 대향진 타측단은 복수 개의 취송류 하강유도유닛 각각과 연결되며, 상기 취송류 하강유도장치의 일측편에서 타측편으로 갈수록, 일측편보다 상대적으로 길이가 길게 구비되어, 상기 취송류 하강유도장치의 호 중심이 편심지도록 연결되는 복수 개의 연결선;을 포함하여, 호소에서 낮은 풍속과 풍향 변화에도 취송류 하강유도장치의 편심과, 상부에 설치된 바람받이판의 기능으로 취송류 하강유도장치가 고정앵커를 축으로 한 방향으로만 회전하게 하여 취송류 하강유도장치와 고정앵커를 연결한 연결선들이 서로 상호 꼬이는 문제를 해소하면서, 심층수로 향하는 수직방향 유동을 효과적으로 유도
