풍력발전기(풍력터빈)는 바람의 운동에너지를 기계적인 에너지로 변환해 전기를 생산하는 장치다. 풍력발전기는 육상이나 해상에 설치된 타워(tower)와, 타워의 상부에 회전하도록 설치되며 발전기를 내장한 나셀(nacelle)과, 발전기의 구동을 위해 나셀에 회전하도록 설치되며 복수의 블레이드(blade)를 갖춘 로터(rotor)등을 포함한다. 상기 풍력발전기는 사용 중 블레이드 및/또는 타워 표면에 먼지나 벌레 등이 부착되어 오염될 수 있고, 블레이드 및/또는 타워에 흠집이나 크랙이 생길 수 있다. 상기 풍력발전기의 오염 및 파손을 에너지 생성효율을 감소시키므로, 주기적으로 블레이드 및 타워의 청소, 검사, 보수, 디아이싱(deicing)과 같은 작업을 필요로 한다. 하지만, 풍력발전기는 거대 구조물이기 때문에 유지관리에 어려움이 많아, 최근에는 보다 안전한 환경에서 블레이드 및 타워의 유지관리를 수행할 수 있도록 하는 전용 장비들이 제안되고 있다. A wind turbine is a device that produces electricity by converting wind's kinetic energy into mechanical energy. Wind power generators are installed on land or at sea, towers are installed to rotate on top of the towers, and have a built-in nacelle. The wind turbines are installed on the nacelle to drive the generator. It includes a rotor etc. equipped. The wind turbine may be contaminated by dust or insects attached to the blade and / or tower surface during use, and may cause scratches or cracks on the blade and / or tower. Pollution and breakage of the wind turbine reduces the energy generation efficiency, and thus requires operations such as cleaning, inspecting, repairing and deicing the blades and towers periodically. However, since the wind turbine is a large structure, it is difficult to maintain, and in recent years, dedicated equipment has been proposed to perform maintenance of blades and towers in a safer environment.
