Description

수중 회전체의 유기물 부착 방지장치 { Maring frowth prevention device for underwater rotating system }Organic matter attachment device for underwater rotating body {Maring frowth prevention device for underwater rotating system}

본 발명은 수중 회전체의 유기물 부착 방지장치에 관한 것으로, 보다 상세하게는 수중체와 회전축의 수직면에 클린부를 형성함으로써 수중에 설치된 회전체의 효율저하를 방지할 수 있는 수중 회전체의 유기물 부착 방지장치에 관한 것이다.The present invention relates to a device for preventing adhesion of organic matter to an underwater rotating body, and more particularly, to prevent organic matter from attaching to an underwater rotating body that can prevent a decrease in efficiency of a rotating body installed in the water by forming a clean part on a vertical surface of the underwater body and the rotating shaft. Relates to a device.

일반적으로, 조류발전기는 바닷물의 밀물과 썰물, 즉 양방향 조류의 흐름을 이용해 전력을 생산하는 장치로서, 육상의 풍력발전기와 유사한 원리가 적용된다.In general, the algae generator is a device for generating electric power by using the tide and low tide of the sea water, that is, the flow of bi-directional tidal flow, a principle similar to that of an onshore wind generator is applied.

육상의 풍력발전기는, 바람의 힘을 이용해 에어 블레이드가 회전되면서 발전기에서 전력을 생산하도록 한 것으로, 조류발전기도 바닷물의 흐름으로 블레이드를 회전시켜 전력을 생산하도록 한 것이다.Onshore wind power generators use the power of the wind to rotate the air blades to generate power from the generators, while the tidal current generators also rotate the blades into the stream of seawater to produce power.

그러나, 바닷물을 이용한 조류발전기는 바닷물의 유체 밀도가 공기에 비해 900배 이상으로 발전량에서도 육상에 비해 많은 양의 전기 생산이 가능하나, 조류를 이용한 발전장치에 사용되는 부속이 상기 밀도 차이를 극복할 수 있는 강도를 가지면서, 해수염분에 의한 부식을 견딜 수 있는 내부식성 소재를 사용해야 한다. However, algae generator using seawater is capable of producing a large amount of electricity compared to the land, even though the fluid density of seawater is more than 900 times that of air, but the parts used in the algae generators can overcome the difference in density. Corrosion resistant materials should be used that have the strength to withstand the corrosion of sea salt.

상기 조류발전장치는 허브와 연결된 회전축이 회전을 하게 되고 이 회전력은 수중체 내부의 기어/발전기를 회전시켜 전기를 발생시키게 되지만, 수중에서는 이런 주요 장치 주변에 동식물 유기체가 부착하게 된다. 물론 바다뿐만 아니라 일반적인 강이나 수중에서는 이끼 등 유착 생물이 존재하는데, 이런 부착 유기물은 회전체에 저항을 증가시키고 회전력을 감소시켜 발전기의 효율을 감소시키는 원인이 된다. The algae generator is a rotational shaft connected to the hub and the rotational force is generated by rotating the gear / generator inside the underwater body, but in the water, the flora and fauna will be attached around the main device. Of course, there are coalesced organisms such as moss in general rivers or water as well as the sea, and these attached organic matters increase the resistance of the rotating body and reduce the rotational force, thereby reducing the efficiency of the generator.

그러므로 수중이나 바다에 설치되어 있는 조류발전장치는 일정 기간 지난 후 수면으로 올려서 장치 주변에 부착되어 있는 유기물을 제거해야 한다. 이로 인해 발전이 정지되어 발전기간이 줄어들고, 유기물 제거를 위해 각 부품을 해상까지 선박으로 이동하여야 하기 때문에 많은 비용, 시간, 비용이 주기적으로 소비되는바 시기적으로 해양환경에 따라 기술적으로도 많은 어려움을 갖고 있다. Therefore, algae generators installed underwater or at sea must be raised to the surface after a certain period of time to remove organic matter from surrounding the apparatus. As a result, power generation is stopped and the interval between generators is reduced, and each part has to be moved to the sea to remove the organic matters. Therefore, a lot of cost, time, and cost are consumed periodically. Have
