[0002] Phased array ultrasonic testing technology is a new technology that has been developed in recent years. With its unique technical advantages, it has solved many engineering problems and is a new direction for the development of the non-destructive testing industry. The main objects of phased array ultrasonic testing are welded joints of pressure equipment. These welds are generally numerous, densely distributed, and have a small testing space, which is not conducive to testing.

[0003] The prior art patent application with publication number CN204575599U achieves wireless transmission of phased array ultrasonic testing signals by setting up a wireless receiver and wireless interface, which facilitates on-site operation and improves the efficiency and safety of on-site phased array ultrasonic testing of small-diameter pipes. It uses soft rubber to make wedges, ensuring a tight fit between the wedges and the workpiece, enhancing the coupling effect, preventing the ultrasonic beam from deflecting again, and improving the controllability of the ultrasonic beam. The probe shell is made of titanium alloy, increasing the probe's service life. The chip is made of piezoelectric ceramic, making the chip cutting more precise, the beam control more accurate, and improving the detection sensitivity.

[0004] However, current devices detect objects by moving a wedge against the object's detection surface. This movement of the wedge across the object's surface can cause wear, and the fixed connection between the wedge and the housing means that the wedge will wear out after prolonged use and cannot be disassembled or replaced.

[0005] Therefore, it is necessary to provide a novel probe for phased array ultrasonic testing of small-diameter pipes to solve the above-mentioned technical problems. Utility Model Content

It solves the problem that current devices use a wedge to contact and move the wedge on the object's surface during testing. However, this method easily causes wear on the wedge, and the fixed connection between the wedge and the housing makes it impossible to disassemble and replace the wedge after prolonged use.

[0008] The housing has a wedge block connected to its bottom, and the bottom of the wedge block has a placement groove.

[0009] A wear-resistant block is disposed inside the placement groove. Two disassembly components are disposed between the wedge and the wear-resistant block. Each disassembly component includes a disassembly groove, inside which a disassembly block is disposed. The bottom of the disassembly block is connected to the wear-resistant block. Adaptive magnetic blocks are connected to both sides of the inner wall of the disassembly groove and both sides of the disassembly block.

[0010] A fixing component is disposed between the wedge and the wear-resistant block. A circuit board, a chip, and a battery are respectively installed inside the housing, and a wireless receiver is connected to the outside of the housing.

[0011] Preferably, the surface of the housing is provided with a cover.

[0012] Preferably, a charging port is provided on the side of the housing.

[0013] Preferably, the fixing component includes a fixing groove, a fixing block is disposed inside the fixing groove, and a bolt is disposed between the fixing block and the wedge block.

[0014] Preferably, the surface of the housing is provided with a picking component, the picking component including a U-shaped fixing rod, and a base is connected to the surface of the U-shaped fixing rod.

[0015] Preferably, a handle is connected to the center of the base surface.

[0016] Preferably, the handle is used for picking up the housing and the wedge.

[0017] Compared with related technologies, the novel probe for phased array ultrasonic testing of small-diameter pipes provided by this utility model has the following beneficial effects:

[0018] This invention provides a novel probe for phased array ultrasonic testing of small-diameter pipes. A placement groove is provided at the bottom of the wedge, a wear-resistant block is placed inside the placement groove, and a disassembly component and a fixing component are provided on the wedge.

[0033] First Embodiment

[0034] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ,in, Figure 1 This is a schematic diagram of the first embodiment of a novel probe for phased array ultrasonic testing of small-diameter pipes provided by this utility model. Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of section B is shown below; Figure 4for Figure 1 A schematic diagram of the overall three-dimensional structure of the device shown; Figure 5 for Figure 1 A schematic diagram of the three-dimensional structure inside the shell is shown. Figure 6 for Figure 1 A three-dimensional structural diagram of the overall external structure of the device shown; Figure 7 for Figure 1 The diagram shows the signal transmission structure of the entire device. A novel probe for phased array ultrasonic testing of small-diameter pipes includes:

[0035] The housing 1 has a wedge 2 connected to its bottom, and the bottom of the wedge 2 has a placement groove 3.

[0036] Wear-resistant block 4 is disposed inside the placement groove 3. Two disassembly components 5 are disposed between the wedge block 2 and the wear-resistant block 4. The disassembly component 5 includes a disassembly groove 51. A disassembly block 52 is disposed inside the disassembly groove 51. The bottom of the disassembly block 52 is connected to the wear-resistant block 4. Adaptive magnetic blocks 53 are connected to both sides of the inner wall of the disassembly groove 51 and both sides of the disassembly block 52.

[0037] The fixing component 6 is disposed between the wedge block 2 and the wear-resistant block 4. The inside of the housing 1 is respectively installed a circuit board 7, a chip 8 and a battery 9. The outside of the housing 1 is connected to a wireless receiver 10.

[0038] The wear-resistant block 4 can be made of ceramic or hard alloy.

[0039] The disassembly groove 51 is located inside the wedge block 2 and above the placement groove 3. The disassembly groove 51 and the disassembly block 52 are T-shaped. The magnetic blocks 53 on the inner wall of the disassembly groove 51 and the side of the disassembly block 52 are oppositely attracted. The bottom end of the fixing block 62 is connected to the wear-resistant block 4. The fixing groove 61 is located on the surface of the wedge block 2. A threaded hole adapted to the bolt 63 is provided on the rear inner wall of the fixing groove 61. The cover 12 can be installed between the bolt and the housing 1.

[0040] Please refer to the following: Figure 5 and Figure 7 It is understood that the phased array ultrasonic testing instrument converts the testing process command into a wireless signal and sends it to the probe body through the probe's wireless interface. The wireless receiver 10 on the probe body receives the wireless signal and transmits it to the circuit board 7. When the circuit board 7 receives the command and analyzes and processes it, it transmits it to the chip 8. When the chip 8 receives the command, it excites the phased array ultrasonic beam. The ultrasonic beam is emitted into the wedge 2 and the wear-resistant block 4. The wedge 2 and the wear-resistant block 4 absorb the clutter and convert the phased array ultrasonic beam into an oblique wave for testing.

[0041] The battery 9, charging port 11, and circuit board 7 are connected by wires.

[0042] The surface of the housing 1 is provided with a cover 12.

[0045] The working principle of the novel probe for phased array ultrasonic testing of small-diameter pipes provided by this utility model is as follows:

[0046] When using the wear-resistant block 4, which is severely worn, it is necessary to first remove the bolt 63 between the fixing block 62 and the wedge block 2. After the bolt 63 is removed, the wear-resistant block 4 is moved from the inside of the placement groove 3 to the outside. When the wear-resistant block 4 moves, it will cause the disassembly block 52 to separate from the disassembly groove 51 on the wedge block 2, and then it can be replaced.

[0047] Compared with related technologies, the novel probe for phased array ultrasonic testing of small-diameter pipes provided by this utility model has the following beneficial effects:
