Background technology
In the petroleum development engineering, need be used to carry the petroleum and natural gas of offshore production at sea in submarine laying submarine oil-transportation, feed channel.Adopt the mode of welding to connect into submarine oil-transportation, tracheae line between pipeline and the pipeline.Between pipeline and the pipeline after the welding,, need detect with the welding quality of detecting instrument to pipe welding seam in order to guarantee between pipeline and the pipeline firm welding of girth joint when docking.
At present, the butt-weld of the submarine pipeline of same inner diameter and identical wall thickness mainly uses full-automatic phased-array ultrasonic pick-up unit to detect.
As shown in Figure 1, existing full-automatic phased-array ultrasonic pick-up unit mainly comprises: support and calibration block 2 that ultrasound examination instrument body, the probe 1 that is connected with ultrasound examination instrument body, confession probe are installed.Before the butt-weld 3 to submarine pipeline detects, at first, be in calibration block 2 carry out the adjusting and determine of correlation parameters such as setting of angle configurations, focal position and the gate of butt-weld 3 with probe 1.Then, carrying out butt girth welding seam again on pipeline detects.
Because the calibration block shape of the full-automatic phased-array ultrasonic pick-up unit of the butt-weld of existing submarine pipeline and thickness and the length that is installed in the probe on the probe bracket are the butt-weld settings by the submarine pipeline of the identical wall thickness of same inner diameter, the calibration block middle part is butt-weld, and two-end thickness is identical; The length of probe bracket is 250 millimeters.Therefore, existing calibration block and probe can only carry out the check of butt-weld of the submarine pipeline of the identical wall thickness of same inner diameter, for check with the butt-weld of uniform internal diameter different wall, the wave beam that produced of probe can not cover whole welding line and wave beam scanning zone separately perpendicular to theoretical groove face on, the position of scanning wave beam, gate and wave beam focal position etc. all will depart from original position, make the heavy wall side can't obtain qualified image and show.For the butt-weld of the submarine pipeline of same inner diameter different wall, generally can only use the ray detection instrument to detect.Because the space is limited on the boats and ships, use the ray detection instrument to detect for the butt-weld of the submarine pipeline of same inner diameter different wall, bring very big difficulty for testing staff's radiation protection, simultaneously, because ray detection instrument detection sensitivity is low, increase unnecessary the reprocessing of field test, influence the whole progress of engineering, reduced the laying speed of submarine oil-transportation, feed channel.
The utility model content
Fundamental purpose of the present utility model is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of capable full-automatic phased-array ultrasonic pick-up unit that improves, it can be tested to the butt-weld of the submarine pipeline of same inner diameter different wall, enlarged the usable range of full-automatic phased-array ultrasonic pick-up unit, improved the utilization factor of full-automatic phased-array ultrasonic verifying attachment, under the situation of ensuring the quality of products, the sensitivity and the submarine oil-transportation of pick-up unit have been improved, the laying speed of feed channel, provide cost savings, reduced since use x radiation x that the ray detection instrument produced to the testing staff bring harm.
The purpose of this utility model is realized by following technical scheme:
A kind of full-automatic phased-array ultrasonic pick-up unit, comprise ultrasound examination instrument body, the support and the calibration block that supply probe to install, the middle part of calibration block is provided with butt-weld, it is characterized in that: this calibration block with the butt-weld edge be as the criterion the two ends wall thickness serve as the difference thick, wherein, the heavy wall side surface is provided with a slope along weld edge, and the excessive ratio of the gradient on slope is 1: 4.
Described calibration block thin-walled side thickness is: 7-25 millimeter scope, heavy wall side thickness are 17-35 millimeter scope.
Described stent length is 290---320 millimeters scopes.
The beneficial effects of the utility model: the utility model can be tested to the butt-weld with the submarine pipeline of uniform internal diameter different wall, enlarged the usable range of full-automatic phased-array ultrasonic pick-up unit, improved the utilization factor of full-automatic phased-array ultrasonic verifying attachment, under the situation of ensuring the quality of products, improved the laying speed of the sensitivity of pick-up unit and submarine oil-transportation, feed channel, provide cost savings, reduced since use x radiation x that the ray detection instrument produced to the testing staff bring harm.

Embodiment
As shown in Figure 2, support and calibration block 2 that the utility model comprises ultrasound examination instrument body, supplies probe 1 to install, the middle part of calibration block is provided with butt-weld 3, because pipeline wall thickness difference, calibration block 2 with butt-weld 3 edges be as the criterion the two ends wall thickness serve as the difference thick, present embodiment is: thin-walled side thickness is that thin-walled side thickness setting is: 7-25 millimeter scope, heavy wall side thickness setting are 17-35 millimeter scope.The probe configuration is to carry out with the thin-walled side, and wherein, the heavy wall side surface is provided with a slope along weld edge, and the excessive ratio of the gradient on slope is 1: 4; Thereby make probe forward position to the distance of axis of a weld certain distance that extends back.The probe bracket length setting is: 290---320 millimeters scopes.
The utility model be applicable to wall thickness poor≤10 millimeters same uniform internal diameter different wall girth joint.
As shown in Figure 3, the utility model principle of work: when being provided with, full-automatic phased-array ultrasonic pick-up unit setting is to be benchmark with the thin-walled side, the scanning wave beam of the appointed area of generation is set in the heavy wall side, the position of gate, wave beam focal position etc. all will depart from original position, make the heavy wall side can't obtain qualified image and show.With the root passage is example, and the scanning angle is 70 degree, adopts " internal loopback (PE) " pattern.The butt girth welding seam of comparable size, incidence point to the distance of axis of a weld is 35 millimeters, the distance of acoustic beam from incidence point to reflecting body is 42 millimeters, with uniform internal diameter different wall butt girth welding seam, incidence point to the distance of axis of a weld is 49 millimeters, the distance of acoustic beam from incidence point to reflecting body is 65 millimeters, and this will increase total system sensitivity.By the shape of change calibration block 2, and adjust full-automatic phased-array ultrasonic pick-up unit correlation parameter, change focuses on time delay etc., makes wave beam focal position 4, position of strobe in the appointed area, and system sensitivity is in acceptable ranges.
