The present invention relates to a phase array ultrasonic probe device for iron detection with excellent preservation of a couplant wherein a probe and a couplant such as a vacuum grease used to increase a contact between inspection objects are easily filled on a wedge of an ultrasonic probe for iron detection having an inclination angle, irregular protrusions and depressions present on a surface of a rail or a crack in various shapes inside the rail are capable of being inspected by increasing the preservation of the couplant, and in addition to improving ultrasonic flaw detection, a replacement period for applying the couplant is extended as the couplant has a longer retention period.

    본 발명은 커플란트의 보존성이 우수한 철로 탐상용 위상배열초음파 탐촉자 장치에 관한 것으로, 경사각을 갖는 철로 탐상용 초음파 탐촉자의 웨지(wedge)에 탐촉자와 피검사체간 접촉성을 높이기 위해 사용하는 진공그리스와 같은 커플란트(couplant)를 손쉽게 충진하고, 커플란트의 보존성을 높임으로써, 레일의 표면에 불규칙한 돌출 및 함몰이 존재하거나 또는 레일 내부에 다양한 형상으로 균열된 상태도 탐상이 가능하고, 초음파 탐상 성능을 향상시킬 뿐만 아니라, 커플란트가 보존 기간이 길어지므로 커플란트를 도포하기 위한 교체 기간이 연장되는 효과가 있다
