Detailed Description
To make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to clearly and completely describe the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
As shown in fig. 1, an apparatus for detecting an ultrasonic sound velocity includes: an ultrasonic probe 1 and a detection body 2. The detection body 2 has a first surface 21 and a second surface 22 opposite to each other, a groove 23 is provided on the first surface 21, the groove 23 has a bottom surface 24 parallel to the second surface 22, and a set distance exists between the bottom surface 24 and the second surface 22. The transmitting end of the ultrasonic probe 1 is associated with the corresponding recess 23 so that the ultrasonic probe 1 can transmit ultrasonic waves toward the bottom surface 24 and the second surface 22 in a direction perpendicular to the bottom surface 24 and receive the ultrasonic waves reflected by the bottom surface 24 and the second surface 22.
The specific working principle is as follows: the ultrasonic signal emitted by the ultrasonic probe 1 that strikes the bottom surface 24 of the recess 23 will have a portion that is reflected directly back to the ultrasonic probe 1 on the bottom surface 24, which is defined as a first reflected wave. Another part of the ultrasonic signal will penetrate the detection body 2 and be reflected back to the ultrasonic probe 1 through the second surface 22, and this part of the ultrasonic signal is defined as a second reflected wave. In operation, the time when the ultrasonic probe 1 receives the first reflected wave and the second reflected wave is recorded, the interval Δ t between the two times the moving time of the ultrasonic wave from the bottom surface 24 to the second surface 22 in the detection body 2 is 2 times, as shown in fig. 1, a set distance d exists between the bottom surface 24 and the second surface 22, and the speed of sound c of the ultrasonic wave is 2d/Δ t.
If the ultrasonic sound velocity detection device is used for detecting the ultrasonic sound velocity when the wall thickness of the pipeline is measured by ultrasonic waves, the manufacturing material of the detection body 2 is the same as that of the pipeline to be detected. In actual use, when the wall thickness of the pipeline is measured by ultrasonic waves, the device can be directly placed in the same environment (for example, the same temperature) as the measured pipeline, and when the wall thickness of the pipeline is measured by ultrasonic waves, the ultrasonic sound velocity is monitored in real time by the detection device of the ultrasonic sound velocity, so that the accuracy of the measurement effect of the wall thickness of the pipeline can be ensured.
Example two
In addition to the first embodiment, as shown in fig. 1, the ultrasonic probe further includes a fixing member 3, and the fixing member 3 is connected to the ultrasonic probe 1 and the inspection body 2, respectively, to fix the ultrasonic probe 1 to the inspection body 2. Thus, the relative fixation of the position between the ultrasonic probe 1 and the detection body can be ensured, and the measurement precision is further ensured.
Specifically, as shown in fig. 1, the detecting device further comprises a fixing plate 4 and a connecting plate 5, wherein the fixing plate 4 is parallel to the first surface 21, and one end of the fixing plate is fixedly connected to the detecting body 2 through the connecting plate 5. The fixing plate 4 is provided with a screw hole 41 whose axis is perpendicular to the first surface 21, the fixing member 3 is a stud matched with the screw hole 41, and the stud is screwed into the screw hole 41 and abuts against the ultrasonic probe 1. This enables the ultrasonic probe 1 to be urged against the recess 23 in the first surface 21 by the screw action of the stud in the screw hole 41.
In actual manufacturing, the detection body 2, the connection plate 5, and the fixing plate 4 are integrally formed, but the present invention is not limited thereto, and the detection body 2, the connection plate 5, and the fixing plate 4 may be separately manufactured and then connected by welding or the like.
EXAMPLE III
On the basis of the first embodiment or the second embodiment, as shown in fig. 1, the electronic device further includes a first clamping portion 6 and a second clamping portion 7, and both the first clamping portion 6 and the second clamping portion 7 are fixedly connected to the second surface 22 and arranged at intervals, so that the external component 8 can be clamped by the first clamping portion 6 and the second clamping portion 7. If this detection device of ultrasonic sound velocity is used for when carrying out ultrasonic measurement to pipeline wall thickness, and external component 8 can be by the pipeline, and at this moment, the material of first joint portion 6 and second joint portion 7 is hot good conductor, is surveyed the pipeline like this when first joint portion 6 of centre gripping and second joint portion 7, can make the temperature that detects body 2 the same with the temperature of being surveyed the pipeline through the heat-conduction effect. Because the pipeline under test is cylindrical, first joint portion 6 has first clamping face 61, and second joint portion 7 has second clamping face 71, and first clamping face 61 is to second clamping face 71 to first clamping face 61 and second clamping face 71 are the curved surface with the pipeline under test shape phase-match. Can increase first joint portion 6 and second joint portion 7 and the laminating area of being surveyed the pipeline like this, and then accelerate the heat conduction between detection body 2 and the pipeline that is surveyed.
Specifically, the first engaging portion 6 and the second engaging portion 7 are integrally formed with the detecting body 2, but not limited thereto. It is also possible to separately manufacture the first clamping portion 6 and the second clamping portion 7, and then fix the first clamping portion 6 and the second clamping portion 7 on the second surface 22 by welding or other methods. It should be noted that, when the first clamping portion 6 and the second clamping portion 7 clamp the pipe to be tested, a gap exists between the pipe to be tested and the second surface 22. This prevents the ultrasonic waves from continuing from the second surface 22 to the wall of the pipe being tested.
As an embodiment, the recess 23 is located between the first snap-in part 6 and the second snap-in part 7 on a projection parallel to the second surface 22.
The above description is only an example of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
