Description

풍력 터빈 블레이드 클리닝시스템Wind Turbine Blade Cleaning System
본 발명은 풍력 터빈 블레이드 클리닝시스템에 관한 것으로, 더욱 상세하게는 풍력 터빈의 타워에 지지되어 블레이드를 따라 승하강하는 리프팅부에 브러쉬를 설치하고, 브러쉬는 블레이드가 통과하는 리프팅부의 내측 둘레를 따라 돌출되도록 형성되어, 회전하는 브러쉬와 블레이드가 밀착되도록 함으로써 리프팅부의 승하강에 따라 별도의 작업 없이도 블레이드의 오염물질을 제거할 수 있도록 하고, 브러쉬는 지지프레임을 중심으로 수직방향의 회전 또는 수평방향의 회전이 가능하도록 하여 블레이드에 대한 밀착면적을 넓힘으로써 세척효율을 높이고 다양한 형상의 블레이드를 세척할 수 있도록 하는 풍력 터빈 블레이드 클리닝시스템에 관한 것이다. The present invention relates to a wind turbine blade cleaning system, and more particularly, a brush is installed on a lifting part supported by a tower of a wind turbine to move up and down along a blade, and the brush protrudes along the inner circumference of the lifting part through which the blade passes. It is formed so that the rotating brush and the blade is in close contact with each other so that the contaminants of the blade can be removed without additional work according to the lifting and lowering of the lifting portion, the brush is rotated in the vertical direction or horizontal direction around the support frame The present invention relates to a wind turbine blade cleaning system that enables the cleaning process to increase the cleaning efficiency by washing the blades of various shapes by increasing the adhesion area to the blades.
풍력터빈(풍력발전기)은 바람의 운동에너지를 기계적인 에너지로 변환해 전기를 생산하는 장치다. 다양한 형식이 있지만, 최근 발전용으로 가장 많이 이용하는 것은 회전축이 바람의 방향과 수평으로 놓이는 프로펠러형 풍력터빈이다. 프로펠러형 풍력터빈은 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)를 포함한다. A wind turbine is a device that produces electricity by converting wind's kinetic energy into mechanical energy. There are many types, but the most common use for power generation is a propeller-type wind turbine whose axis of rotation lies horizontally with the wind direction. Propeller-type wind turbines are installed on land or at sea, towers that rotate on top of the tower, have a built-in generator, and a nacelle to drive the generator. It includes a rotor with).
이러한 풍력터빈은 사용 중 블레이드 및/또는 타워 표면에 먼지나 벌레 등이 부착되어 오염될 수 있고, 블레이드 및/또는 타워에 흠집이나 크랙이 생길 수 있다. 특히 동절기에는 블레이드 리딩엣지(Leading edge)에 결빙이 생길 수도 있다. 블레이드(또는 타워) 표면의 이물질이나 얼음은 풍력터빈의 효율저하를 초래할 수 있고, 블레이드(또는 타워)의 결함은 방치할 경우 파손의 원인이 될 수 있다. 따라서 풍력터빈은 블레이드(또는 타워)의 청소, 검사, 보수, 디아이싱(deicing)과 같은 주기적인 유지관리가 필요하다. Such a 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. In winter, freezing may occur at the blade leading edge. Foreign matter or ice on the surface of the blade (or tower) can result in a decrease in the efficiency of the wind turbine, and defects in the blade (or tower) can cause damage if left unattended. Thus, wind turbines require periodic maintenance, such as cleaning, inspecting, repairing and deicing blades (or towers).
하지만, 풍력터빈은 타워의 높이가 대략 100미터에 이르고, 블레이드의 길이도 40 ~ 70미터 또는 그 이상에 이르는 거대 구조물이기 때문에 유지관리에 어려움이 많으며, 특히 블레이드에 부착된 오염물질을 제거하기 위해서는 도 1의(a)에 도시된 바와 같이 작업자가 줄에 매달려 블레이드를 청소하거나 도 1의(b)에 도시된 바와 같이 블레이드에 고압의 물을 분사하여야 했기 때문에, 작업자가 추락의 위험에 노출되고 상당한 작업시간이 소요되는 문제가 있었다. However, the wind turbine is difficult to maintain because the tower is approximately 100 meters high and the blades are 40 to 70 meters or more in length, which is difficult to maintain, especially to remove contaminants attached to the blades. The operator is exposed to the risk of falling because the operator has to hang on a string to clean the blades or spray high pressure water on the blades as shown in FIG. 1 (b) as shown in FIG. There was a problem that required considerable work time.
또한, 본 출원인은 블레이드의 유지, 관리를 용이하도록 하기 위해 아래 특허문헌과 같은 풍력발전기 유지보수용 플랫폼을 개발하여 작업시간을 단축하고 작업자의 안전을 도모하도록 하였으나, 여전히 수작업에 의해 블레이드의 청소를 실시해야 하므로, 많은 작업 시간이 소요되고, 블레이드의 청소가 제대로 이루어지지 않는 문제가 있었다. In addition, the present applicant has developed a wind turbine maintenance platform such as the following patent document to facilitate the maintenance and management of the blade to shorten the working time and promote the safety of the operator. Since it has to be carried out, it takes a lot of work time and there was a problem that the blade is not cleaned properly.
