Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This embodiment provides a technical solution: a portable ultrasonic weld detector, including a detection chamber 1, an ultrasonic probe 11 disposed on the left side of the detection chamber 1, and a support mechanism 2;

[0024] Support mechanism 2 includes a convergence chamber 21, a support plate 22, a support 23, a partition 24, and an inclined surface 26. The convergence chamber 21 is located at the upper end of the rear surface of the detection chamber 1.

The front end of the partition 24 is provided with symmetrically distributed locking slots 1, which are all engaged with the longitudinally adjacent locking posts 25. The upper end of the support plate 22 is fixedly connected to the drive seat 27. The rear end of the detection chamber 1 is fixedly connected to the collection chamber 12. The upper end of the collection chamber 12 is provided with symmetrically distributed locking slots 23, which are all engaged with the longitudinally adjacent locking posts 25. The corresponding end of cable 10 is snapped in place. The support plate 22 is pushed backward by the drive seat 27, causing it to rotate backward around the central axis of the pin. The support plate 22 moves away from the collection chamber 21, and simultaneously, the partition plate 24 moves backward via the two supports 23. As the partition plate 24 rotates backward around the central axis of the pin, the snap-fit ​​of the first slot of the partition plate 24 engages with the corresponding snap-fit ​​post 25, ending the sealing of the upper end of the collection chamber 12. When the lower end of the rear surface of the support plate 22 is parallel to the inclined plane 26, the two supports 23 and... The rear ends of the partition 24 are in contact with the rear end of the detection chamber 1. Then the detection chamber 1 is placed in the working area, and the support plate 22, the detection chamber 1 and the working plane form a triangle to achieve stable support for the detection chamber 1. At the same time, the support 23 and the partition 24 support the rear surface of the detection chamber 1, further improving the stable support of the support mechanism 2 for the detection chamber 1. Then the cable 10, connector 9 and ultrasonic probe 11 inside the collection chamber 12 are removed. Then the connector 9 is inserted into the upper end of the data connector 8.

[0025] The following configuration is provided: a microcontroller 3 is installed at the upper end of the rear inner wall of the detection chamber 1; a lithium battery 7 is installed at the lower end of the rear inner wall of the detection chamber 1; the input terminal of the microcontroller 3 is electrically connected to the output terminal of the lithium battery 7; an ultrasonic generator 4 is installed at the left end of the rear inner wall of the detection chamber 1; an ultrasonic detection plate 5 is installed at the right end of the rear inner wall of the detection chamber 1; the input terminal of the ultrasonic generator 4 is electrically connected to the output terminal of the microcontroller 3; the output terminal of the ultrasonic detection plate 5 is electrically connected to the input terminal of the microcontroller 3; a data connector 8 is installed at the upper end of the detection chamber 1; a connector 9 is installed at the upper end of the data connector 8; the connector 9 is bidirectionally electrically connected to the ultrasonic probe 11 via a cable 10; and the data connector... The input terminal of connector 8 is electrically connected to the output terminal of ultrasonic generator 4. The output terminal of connector 8 is electrically connected to the input terminal of ultrasonic detection board 5. Symmetrically distributed speakers 6 are provided at the lower end of the rear inner wall of detection chamber 1. The input terminals of both speakers 6 are electrically connected to the output terminals of microcontroller 3. A display screen 14 is provided in the middle of the front surface of detection chamber 1. Keypads 15 are provided at both ends of the front surface of detection chamber 1. Keypads 15 are bidirectionally electrically connected to microcontroller 3. The input terminal of display screen 14 is electrically connected to the output terminal of microcontroller 3. Commands are issued to microcontroller 3 through keypads 15, and microcontroller 3 controls ultrasonic generator 4 to operate. 4. The system generates ultrasonic waves of the corresponding frequency and transmits the ultrasonic signal through data connector 8 to connector 9, then through cable 10 to ultrasonic probe 11. Ultrasonic probe 11 converts the ultrasonic signal into ultrasonic waves of the corresponding frequency and emits high-frequency ultrasonic pulses towards the weld area. When the ultrasonic waves encounter defects (such as cracks, pores, slag inclusions, etc.) or structural boundaries within the weld, reflection and scattering occur. Ultrasonic probe 11 captures the reflected ultrasonic signals and converts them into electrical signals. These electrical signals are then transmitted through cable 10 to connector 9, which in turn transmits the electrical signals to data connector 8, thereby enabling… The ultrasonic testing board 5 receives the echo reflected from the ultrasonic probe 11. The ultrasonic testing board 5 converts the reflected ultrasonic pulses back into electrical signals, which are then processed by the onboard receiver and analog-to-digital converter of the ultrasonic testing board 5. After processing, the ultrasonic testing board 5 transmits the signal to the signal receiving end of the microcontroller 3. The microcontroller 3 enables the display screen 14 to operate. The display screen 14 displays the reflected ultrasonic signal in the form of waveforms or images on the screen. By analyzing the amplitude, position, and time of the reflected wave, it is possible to determine whether there are defects inside the weld, as well as the type, size, and location of the defects, thereby realizing ultrasonic testing of the weld.

[0026] The working principle of the portable ultrasonic weld detector provided by this utility model is as follows: During operation, the operator first moves the support plate 22 backward via the drive seat 27. The support plate 22 rotates backward around the central axis of the pin, moving away from the collection chamber 21. Simultaneously, the two supports 23 drive the partition plate 24 to move backward. When the partition plate 24 rotates backward around the central axis of the pin, the latch of the partition plate 24 engages with the corresponding latch 25, thus ending the sealing of the upper end of the collection chamber 12. When the lower end of the rear surface of the support plate 22 is parallel to the inclined plane 26, the rear ends of the two supports 23 and the partition plate 24 are in contact with the rear end of the detection chamber 1. Then, the detection chamber 1 is placed in the working area, forming a triangle with the support plate 22, the detection chamber 1, and the working plane to achieve stable support for the detection chamber 1. Simultaneously, the support 23 and the partition 24 support the rear surface of the detection chamber 1, further enhancing the stability of the support mechanism 2. Then, the personnel remove the cables 10, connectors 9, and ultrasonic probes 11 from inside the collection chamber 12. Next, the connector 9 is plugged into the upper end of the data connector 8. Then, the personnel issue commands to the microcontroller 3 via the keypad 15. The microcontroller 3 controls the ultrasonic generator 4 to operate, producing ultrasonic waves of the corresponding frequency and transmitting the ultrasonic signal. The data is transmitted from the data connector 8 to the connector 9, and then through the cable 10 to the ultrasonic probe 11. The ultrasonic probe 11 converts the ultrasonic signal into ultrasonic waves of the corresponding frequency and emits them. The high-frequency ultrasonic pulses are emitted towards the weld area. When the ultrasonic waves encounter defects (such as cracks, pores, slag inclusions, etc.) or structural boundaries inside the weld, reflection and scattering occur. The ultrasonic probe 11 captures the reflected ultrasonic signals and converts them into electrical signals. The converted electrical signals are then transmitted to the connector 9 through the cable 10. The connector 9 transmits the electrical signals to the data connector 8, thereby enabling the ultrasonic detection board 5 to receive the ultrasonic signals. The echo reflected back from the wave probe 11 is converted into an electrical signal by the ultrasonic testing board 5. The signal is then processed by the onboard receiver and analog-to-digital converter of the ultrasonic testing board 5. The processed signal is then transmitted to the signal receiving end of the microcontroller 3. The microcontroller 3 enables the display screen 14 to operate. The display screen 14 displays the reflected ultrasonic signal as a waveform or image on the screen. By analyzing the amplitude, position, and time of the reflected wave, the inspector can determine whether there are defects inside the weld, as well as the type, size, and location of the defects, thereby realizing the ultrasonic testing of the weld.

[0027] It is worth noting that the ultrasonic generator 4 disclosed in the above embodiments can be an ultrasonic generator with a frequency of 28KHZ-40KHZ, and the ultrasonic generator of the OU5100 ultrasonic flaw detector is preferred. The ultrasonic detection board 5 can be a UTM ultrasonic detection board. The microcontroller 3 controls the operation of the ultrasonic generator 4, ultrasonic detection board 5, speaker 6, display screen 14 and keypad 15 using methods commonly used in the prior art.
