[0002] Ultrasonic testing is one of the most commonly used methods for detecting internal defects in pressure-bearing equipment, and it is particularly sensitive to volumetric defects. Ultrasonic testing requires the use of an ultrasonic flaw detection device. The ultrasonic wave emitted by the ultrasonic probe is transmitted from the surface of the workpiece to the inside of the workpiece. When encountering the defects of the workpiece and the bottom of the workpiece, it generates reflected waves, forming pulse waveforms on the display screen of the ultrasonic flaw detection device. The position and size of the defects of the workpiece can be detected based on these formed pulse waveforms, and the nature and harmfulness of the defects can be preliminarily judged.
[0003] At present, when ultrasonic flaw detection is performed, workers usually hold the ultrasonic probe and press it on the surface of the workpiece to be tested. However, when manually operated, the ultrasonic probe is often slippery due to the coupling agent around it. This situation is easy to occur especially when testing in a small space or at high altitude, which not only delays the progress of the test, but also easily damages the ultrasonic probe, resulting in unnecessary cost consumption.

DETAILED DESCRIPTION
[0023] The present application provides a portable ultrasound probe clamping device, which has a simple structure and is easy to disassemble, and can be used to effectively protect the ultrasound probe.
[0024] In a preferred embodiment of the present application, a portable ultrasound probe clamping device is provided, for example, Figure 1-Figure 3 .like Figure 1 As shown, the portable ultrasound probe clamping device comprises: a probe protection shell 1, a finger ring 2 and a retractable rope 3 connecting the probe protection shell 1 and the finger ring 2; the probe protection shell 1 comprises: a box-shaped shell 11 with an opening at the bottom, a connector 12 located at the top of the box-shaped shell 11 and a plurality of clamping members ( Figure 1(not shown); wherein: the connector 12 is provided with a through hole for inserting the retractable rope 3; the clamping member is configured to clamp the ultrasonic probe in the box-shaped housing 11, and the clamping member includes a compression spring and a spring pressure plate, one end of the compression spring is welded to the inner wall of the box-shaped housing 11, and the other end of the compression spring is welded to the spring pressure plate, and the spring pressure plate is in contact with the ultrasonic probe. Preferably, when welding the clamping member of the portable ultrasonic probe clamping device, the compression spring and the spring pressure plate are first spot welded together, and then the compression spring that has been welded to the spring pressure plate is spot welded on the inner wall of the box-shaped housing 11. Such a welding method is easier to operate and is conducive to adjusting the parallelism between the spring pressure plate and the inner wall of the box-shaped housing 11. When the portable ultrasonic probe clamping device provided by the present application is used to perform ultrasonic flaw detection, the ultrasonic probe to be used is loaded into the box-shaped housing 11, so that the ultrasonic probe contacts the spring pressure plate and the spring pressure plate is in a compressed state, thereby stably clamping the ultrasonic probe inside the box-shaped housing 11, and the bottom of the box-shaped housing 11 is open to expose the piezoelectric chip protective layer of the ultrasonic probe, and the piezoelectric chip protective layer is used to contact the workpiece to be detected to perform ultrasonic flaw detection. Advantageously, the staff can put the finger ring 2 on the finger of the operator and fine-tune the detection position of the ultrasonic probe through the telescopic rope 3. When used to perform detection in a narrow space (for example, at the butt weld of the inlet and outlet pipes of the gasifier radiation waste pot), such a configuration can not only prevent the ultrasonic probe from accidentally falling and being damaged, but also can use the traction of the telescopic rope 3 to quickly and flexibly adjust the position of the ultrasonic probe, thereby improving the detection efficiency.
[0025] The portable ultrasonic probe clamping device provided in the present application can be used to clamp an ultrasonic probe that requires an external power supply or does not require an external power supply. When the ultrasonic probe requires an external power supply, the power connector can extend through the gap between the spring pressure plate and the inner wall of the box-shaped shell 11. In a preferred embodiment of the present application, a circular hole for extending the power connector of the ultrasonic probe is also provided on the box-shaped shell 11. The circular hole can be provided on any inner wall of the box-shaped shell 11 to facilitate the access of the power connector.
[0026] In a preferred embodiment of the present application, the box-shaped housing 11 is a cuboid with an open bottom, and the cuboid box-shaped housing 11 conforms to the shape of most ultrasonic probes on the market. In a specific embodiment, the inner dimensions of the box-shaped housing 11 are: 42mm×24mm×24mm (length×width×height), and its length and width are 1.2 times that of a conventional ultrasonic probe, and its height is 0.8 times that of a conventional ultrasonic probe (to ensure that the piezoelectric wafer protection layer of the ultrasonic probe extending from the bottom of the box-shaped housing 11 can fully contact the workpiece to be detected), and the elasticity and compression degree of the compression spring can be specifically set according to the ultrasonic probe used, so as to firmly clamp the ultrasonic probe in the box-shaped housing 11. Those skilled in the art can understand that as long as the ultrasonic probe can be clamped in the box-shaped housing 11 by the clamping member, the box-shaped housing 11 can have any suitable geometric structure.
[0027] In a preferred embodiment of the present application, the box-shaped housing 11 may have a right pentagonal prism shape with a pentagonal side (i.e., a shape obtained by cutting off a right triangular prism along one edge of a rectangular parallelepiped), for example Figure 1 In such an embodiment, a circular hole for extending the power connector of the ultrasonic probe can be opened on the inclined side wall of the box-shaped housing 11 without the opposite side wall. Such a structure is more suitable for the structure of the ultrasonic probe that requires an external power supply. The power connector of the ultrasonic probe can be conveniently connected through the circular hole on the inclined side wall of the box-shaped housing 11.
[0028] In some embodiments, the box-shaped housing 11 is provided with clamps on at least 2, 3, 4 or 5 inner walls. In a preferred embodiment of the present application, the box-shaped housing 11 is a cuboid with an open bottom, and clamps are provided on the 5 inner walls of the cuboid housing. In another preferred embodiment of the present application, the box-shaped housing 11 is in the shape of a straight pentagonal prism with pentagonal sides (as described above), and clamps are provided on the 5 inner walls of the box-shaped housing 11 except the inclined side wall (as defined above), such as Figure 2 and Figure 3 As shown. Each clamping member provided on the inner wall may include a spring pressure plate and a plurality of compression springs. Figure 2 and Figure 3As shown, the first clamping member 131 may include a first spring pressure plate 1311 and two first compression springs 1312 and 1313; the second clamping member 132 may include a second spring pressure plate 1321 and six second compression springs 1322, 1323, 1324, 1325, 1326 and 1327; the third clamping member 133 may include a third spring pressure plate 1331 and six third compression springs 1332, 1333, 1334, 1335, 1336 and 1337; the fourth clamping member 134 may include a fourth spring pressure plate 1341 and six fourth compression springs 1342, 1343, 1344, 1345, 1346 and 1347; the fifth clamping member 135 may include a fifth spring pressure plate 1351 and four fifth compression springs 1352, 1353, 1354 and 1355. It is easy for those skilled in the art to understand that Figure 2 and Figure 3 The components with brackets represent two components arranged front and back in the cross-sectional view, and such two components are identical and their labels can be used interchangeably. Preferably, the number and position of the compression springs can be reasonably set according to the specific shape and size of the box-shaped housing 11 and the size of the ultrasound probe to be clamped.
[0029] In a preferred embodiment of the present application, the box-shaped housing 11 is made of S30408 sheet material, which has a strong and corrosion-resistant structure and is suitable for use in environments with high temperatures and pressures and the presence of coupling agents. In a preferred embodiment of the present application, the retractable rope 3 is made of polyester (polyester fiber), which has strong toughness and elasticity, which can not only ensure the firm connection between the finger ring 2 and the probe protective shell 1, but also has a certain degree of stretchability, which is very beneficial for ultrasonic detection in a narrow space. In another preferred embodiment of the present application, the retractable rope 3 can be a telescopic rod with adjustable length and angle, and the telescopic rod is connected to the connector 12 by a fixable hinged manner to more accurately adjust the position and angle of the ultrasonic probe. In a preferred embodiment of the present application, the compression spring is made of S304 stainless steel, which has the characteristics of rust resistance, corrosion resistance, good elasticity and high strength, and is suitable for use in high temperature and high pressure scenarios such as gasification furnaces.
[0030] In a preferred embodiment of the present application, the spring pressure plate is made of a wear-resistant material. Preferably, the wear-resistant material can be a metal wear-resistant material such as a high manganese alloy, chromium-containing cast iron, and a wear-resistant copper alloy. In a preferred embodiment of the present application, a flexible gasket is further provided between the spring pressure plate and the ultrasonic probe to reduce damage caused by contact and friction between the spring pressure plate and the ultrasonic probe. Preferably, the flexible gasket can be a rubber gasket, a metal gasket, or a plastic gasket.
