Description

무동력 물 순환 장치{Water rotation apparatus}Non-powered water circulation device

본 고안은 저수지나 호수 및 댐등에 고여 있는 물을 상하 순환시켜 물속의 용존 산소량을 높여주기 위한 것으로, 풍력을 이용한 회전동력으로 스크류를 회전시켜 담수를 상하 순환시키는 물 순환장치에 관한 것이다.The present invention is to increase the dissolved oxygen in the water by circulating the water accumulated in the reservoir, lake, and dam up and down, and relates to a water circulation device for circulating fresh water up and down by rotating the screw with a rotating power using wind power.

저수지나 호수 및 댐등에 고여 있는 물은 표층과 저층의 수온이 서로다른 성층현상이 높게 발생하고 있는데, 이러한 성층현상은 여름철엔 표층의 온도는 높고 저층의 온도는 낮으며, 겨울철에는 반대로 표층의 온도는 낮고 저층의 온도가 높은 현상을 말한다.Water accumulated in reservoirs, lakes, and dams has high stratospheric phenomena with different surface and low water temperatures. These stratospheric phenomena have high temperatures in the summer and low temperatures in the summer, and low temperatures in winter. Refers to a phenomenon in which the temperature of the lower layer is high.

이러한 성층현상은 저층에 존재하는 물속의 용존 산소량 부족을 초래하게 되고, 이로 인해 바닥에 퇴적된 인성분의 용출을 촉진시켜 담수된 수질을 떨어트리게 된다.This stratification results in a lack of dissolved oxygen in the water present in the bottom layer, thereby facilitating the dissolution of phosphorus deposits deposited on the floor, thereby degrading the fresh water quality.

물속에 인이나 질소의 용출이 많으면 조류번식의 영양원이 풍족하여 부영양화가 진행되며, 이를 해결하기 위해서는 담수된 저층부의 물과 상층부의 물을 서로 순환시켜 주면된다.If phosphorus or nitrogen is eluted in the water, eutrophication proceeds due to abundant nutrient sources of algae breeding. To solve this problem, the fresh water of the lower layer and the upper layer of water are circulated with each other.

담수된 저층부의 물과 상층부의 물을 순환시키기 위해서는 전기나 기름 등의 동력원을 필요로 하여 운전비용이 많이 소요될 뿐만아니라 동력원으로 부터 멀리 떨어진 곳에서는 사용할 수 없는 문제점이 있다.In order to circulate the fresh water of the lower layer and the upper layer of water, it requires a power source such as electricity or oil, which requires a lot of operating costs, and there is a problem in that it cannot be used in a place far from the power source.

또한 상기의 문제점으로 인하여 저수지나 호수 및 댐과 같이 광활한 면적에서는 동력원이 설치되는 지면 근처만을 순환시킬 수 있어 기대효과가 미비한 실정이다.In addition, due to the above problems, in a large area such as a reservoir, a lake, and a dam, it is possible to circulate only near the ground where the power source is installed.

본 고안은 바람에 민감한 팬을 이용하여 회전동력을 발생하고, 상기 회전동력을 이용하여 물속에 잠긴 스크류를 회전시킴으로써 비용이 들지 않으며 동력원으로 부터의 거리에 제한을 두지 않고도 저층부의 물과 상층부의 물을 순환시키도록 하는 것이다.The present invention generates rotational power by using a fan sensitive to wind, and it is inexpensive by rotating the submerged screw using the rotational power, and the water in the lower part and the upper part without limiting the distance from the power source. To circulate.

이러한 본 고안은 고정판에 부양체를 달아 수면에 떠 있게 하고, 고정판 상부에 팬을 설치하여 회전동력을 발생시키며, 고정판 하부에는 물속에 잠기는 배출관을 설치하고, 상기 배출관 내부에 스크류를 설치하되 상기 스크류는 팬의 회전동력에 의해 회전되게 하므로써 이루어진다.The present invention is attached to the fixing plate floating on the water surface, and install the fan on the top of the fixing plate to generate the rotational power, install the discharge pipe submerged in the water below the fixing plate, install the screw inside the discharge pipe but the screw This is accomplished by being rotated by the rotational power of the fan.
