Ultrasound wave angle regulator in water seaoning Ultrasonic DetectionTechnical field
The invention belongs to the water logging ultrasonic non-destructive inspection techniques field of nuclear power station small-bore tubing shape equipment inside surface.
Background technology
Nuclear power station has much small-bore tubing shape equipment, according to the requirement of ASME specification, needs to do regular detection to wherein some little tubular equipments weld seam, for the equipment be arranged in water, just needs to carry out water logging Ultrasonic NDT.
For the said equipment, some tubular equipments can not carry out outer wall detection due to location arrangements, can only carry out from inside.At present, the detection method that tubing structure adopts usually is contact Ultrasonic Detection.But because pipe with small pipe diameter equipment caliber is less, not easily arrange contact sonde; Equally, limit by caliber, too many probe and cable can't be arranged; In addition, for the small tubes that some tube walls are thicker, water seaoning also requires enough underwater sound journey distances, so, adopt the detection method of prior art to be difficult to obtain good testing result.
Summary of the invention
The present invention seeks to the water logging Ultrasonic NDT for the small-bore tubing shape equipment inside surface of nuclear power station and design a kind of structure, realizing the location to small-bore tubing weld seam multiple angles of incidence degree and quantitative ultrasonic examination.
The present invention so realizes:

Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
The device of a kind of remote controlled ultrasonic reflections angle in water seaoning Ultrasonic Detection that patent of the present invention proposes as depicted in figs. 1 and 2, comprising: mount pad 1, locating water immersion probe 2, rotary cylinder 3, quantitatively immersion probe 4, probe clamper 5, catoptron 6, motor 7, pointer 8, Reflector base 9.Following multiple functional structure can be divided into.
1) ultrasonic reflections structure
Ultrasonic reflections structure comprises locating water immersion probe 2, quantitatively immersion probe 4 and catoptron 6.During detection, locating water immersion probe 2 or the ultrasound wave that quantitatively immersion probe 4 is launched add underwater sound journey by the reflection of catoptron 6, can solve the problem that in pipe with small pipe diameter large wall thickness pipe testing process, underwater sound journey is too small.
In the present embodiment, the surface of catoptron 6 adopts the shape of concave mirror, can make that the ultrasonic wave acoustic beam dispersed is parallel to be incided in pipe welding seam, and raising is checked on the quality.
2) mirror angle governor motion
Ultrasonic incident angle is realized by catoptron 6, catoptron 6 is connected with the stator of motor 7, and Reflector base 9 is connected with the rotor of motor 7, when stepper motor 7 works, the Reflector base 9 be connected with rotor maintains static, and the rotation that the catoptron 6 be connected with stator is relative.Catoptron 6 is installed pointer 8 to indicate the anglec of rotation.Make catoptron 6 deflect certain angle by Long-distance Control motor 7, and then change hyperacoustic incident angle.
The anglec of rotation of catoptron 6 and the umber of pulse of motor 7 controller have certain relation, and the ultrasonic incident angle required according to scanography determines that the angle of catoptron 6 and the corresponding umber of pulse of stepper motor 7 controller can realize the rotation of catoptron 6.
3) probe switching mechanism
Probe switching mechanism comprises: locating water immersion probe 2, rotary cylinder 3, quantitatively immersion probe 4 and probe clamper 5.Locating water immersion probe 2 and quantitative immersion probe 4 are arranged on probe clamper 5, and probe clamper 5 is connected with rotary cylinder 3.Select the type of immersion probe by controlling rotary cylinder 3, and then determine test mode.
Rotated by long-range pneumatic control rotary cylinder 3, drive probe clamper 5 to rotate, need to select immersion probe type according to inspection.
Locating water immersion probe 2 is for positioning for weld seam, and quantitative immersion probe 4 is for carrying out determining quantitative analysis for weld seam.Both coordinate, and can complete the task of multiple probe in prior art.
In the inside surface ultrasonic examination of small-bore tubing shape equipment, said structure can realize location and quantitative multi-angle inspection work at small space.
Above embodiments of the invention are explained in detail, above-mentioned embodiment is only optimum embodiment of the present invention, but the present invention is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
