The invention relates to an ultrasonic transducer device for detecting a light pore composite material. The ultrasonic transducer device comprises an ultrasonic transducer, silicon rubber wheel leather, a movable universal wheel, a spring device (a force adjusting mechanism), a rigid material shell, a big bracket and a universal wheel bracket. The ultrasonic transducer device can realize dynamic, rapid, dry coupling and transmission type detection of internal defects of a tested piece; meanwhile, as far as a composite material plate with relatively big area is considered, a central part is difficult to detect when the composite material plate is detected via a transmission method (that is mainly to say that two ultrasonic transducers are difficult to guarantee to be always vertical and opposite to a same beeline), so that a special bracket structure is designed, and more accurate, more flexible and quicker detection is realized.
