Abstract

조류 발전기용 샤프트, 상기 조류 발전기용 샤프트를 포함하는 조류 발전기, 및 조류 발전 시스템에서, 상기 조류 발전기용 샤프트는 주축부, 하부축부 및 플로팅 부재를 포함한다. 상기 주축부는 하단에 결합부가 형성되고, 상기 하부축부는 상기 결합부를 통해 상기 주축부와 결합되며, 상기 주축부가 회전하도록 지지한다. 상기 플로팅 부재는 상기 결합부 내에 상기 주축부 및 상기 하부축부 사이 공간에 배치되어 상기 결합부 내부로의 해수의 유입을 방지한다. 이로써, 상기 주축부의 하부영역에 해수의 유입을 방지하여, 해수에 의한 부식이나 마모를 방지할 수 있다.
