Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
Pipeline 1 suffers erosion equivalent damage defect, is a kind of extremely serious potential in the case where being not enough to cause leakage
Danger, therefore the detection to the damage defect of pipeline 1 is very necessary for the security of piped water supply.The utility model is intended to
Detect the security performance of pipeline 1 in advance to greatest extent, eliminate potential danger to greatest extent, so for detection technique
For, research of the present utility model is with more practical application and using generality.So the utility model selection is different
The pipeline 1 (damage hole depth is not less than tubing wall thickness) of degree of injury, is target detection thing, carries out ultrasound examination damage and lack
The research of the device and method for the technology of falling into.
A kind of ultrasound damage device of water supply line is the utility model is related to, is made up of device body, such as Fig. 1 and Fig. 2
Shown, described device body includes two piezoelectric ceramic pieces 2, and one of piezoelectric ceramic piece 2 is connected with oscillography by signal wire
Device 5, another piezoelectric ceramic piece 2 are connected with supersonic generator 3 by signal wire, and the supersonic generator 3 is connected with PC
Machine 4.In use, two single-points of piezoelectric ceramic piece 2 are arranged on the outer wall of pipeline 1, PC 4 controls the transmitting of supersonic generator 3 to encourage
Magnetic ultrasonic signal, through piezoelectric ceramic piece 2 and pipeline 1, oscillograph 5 receives feedback wave signal, shown.
The ultrasound damage method of water supply line based on said apparatus, the utility model is using transmitting different frequency and not
With the ultrasonic testing signals of amplitude intensity, some numbering pipelines 1 of Injured level are acted on, then according to oscillograph 5
The feedback wave signal received, Treatment Analysis corresponding to progress, specifically includes following steps respectively：
Step 1, water will be respectively filled with inside some pipelines 1, and the numbering such as A, B, C is carried out to pipeline 1.
Step 2, single-point is distinguished on the every outer wall of pipeline 1 two piezoelectric ceramic pieces 2 are set, every group of piezoelectric ceramic piece 2
Line is parallel with the axis of pipeline 1 where it, and one of piezoelectric ceramic piece 2 receives the excitation that supersonic generator 3 is launched
Ultrasonic signal, is transmitted to another piezoelectric ceramic piece 2 through pipeline 1, is transferred to oscillograph 5 by signal wire, is shown feedback
Ripple signal.Wherein, the spacing of every group of piezoelectric ceramic piece 2 is 12cm, and carrying out segmentation successively to the other end from one end of pipeline 1 examines
Survey.The excitation ultrasonic signal is sinusoidal signal, and tranmitting frequency is 20kHz~100kHz, and amplitude is ± 5v~± 10v.
Step 3, the 5 feedback wave signals received are connect to oscillograph and carry out Data Management Analysis, judge every group of piezoelectric ceramic piece
Duct section between 2 has not damaged：If feedback wave signal magnitude and pumping signal size are essentially identical, illustrate two piezoelectricity potteries
Duct section not damaged hole 6 between ceramics 2；If feedback wave signal substantially reduces compared with pumping signal, illustrate two piezoelectric ceramics
Duct section between piece 2 has damage hole 6.
Step 4, complete after once surveying damage, repeated the above steps two and step 3, and every pipeline 1 is detected paragraph by paragraph,
Until the detection of every pipeline 1 is completed, and the degree of injury situation between more different pipelines 1：Identical excitation ultrasonic signal
Under intensity, the feedback wave signal amplitude of integral conduit 1 is maximum, and the feedback wave signal amplitude of the pipeline 1 for the damage that suffered erosion
It is obviously reduced, and as the increase of erosion degree, feedback wave signal amplitude also increase accordingly, but not exceed integral conduit 1
Feedback wave signal amplitude.Under different exciting ultrasonic signal strength, for integral conduit 1, excitation ultrasonic signal voltage amplitude
Value reduces, and feedback wave signal amplitude is obviously reduced, and the pipeline 1 for having corroded a little, same that excitation ultrasonic signal is presented
Voltage magnitude reduces, the rule that feedback wave signal amplitude reduces, and is that the point corrosion pit of pipeline 1 is deeper, the maximum electricity of feedback wave signal
Pressure amplitude value slightly increases on the contrary.Further, since the emitting voltage amplitude of supersonic generator 3 doubles, feedback wave signal is maximum
Voltage magnitude does not have equal proportion increase, illustrates that both have and obvious associate but be not linear correlation.
Although function of the present utility model and the course of work are described above in conjunction with accompanying drawing, the utility model is simultaneously
Above-mentioned concrete function and the course of work are not limited to, above-mentioned embodiment is only schematical, rather than limitation
Property, one of ordinary skill in the art, will not departing from the utility model aims and right under enlightenment of the present utility model
Ask under protected ambit, many forms can also be made, these are belonged within protection of the present utility model.
