Ultrasonic probe of tube insertion type

Abstract

Abstract PURPOSE: To feed the power to a drive unit from the outside of a test tube and to improve the insertability in a bent tube portion by connecting the drive unit to the back of a rotor by means of a bendable connecting jig. CONSTITUTION: A rotor 5 supports an acoustic mirror 3 and is formed in the passage of ultrasonic beam with an opening 5a. The rotor is made to rotate on the outer circumference of a probe body 2. A drive unit 6 is equipped with such gear mechanism 13 and motor 7 as are used to lead the transmission and detection cable 10 connected to the prove body 2 to the outside of the rotary portion of the rotor and is made to have the shaft of rotation 13a connected to the shaft of the rotor 5 through a connecting jig 12a with can be bent. Thus, it is possible to supply stable power, even when flaw detection of a long tube is performed continuously for a long time, and to improve the insertion into a test tube having a bent portion.
