Description

Technical Field

[0001] The utility model relates to the field of ultrasonic flaw detection, in particular to a digital ultrasonic flaw detector. Background Art

[0002] With the continuous development of industrial technology, the requirements for the detection of internal defects in materials are becoming higher and higher. As an efficient and non-destructive detection method, ultrasonic flaw detection technology has been widely used in the field of material testing. Ultrasonic flaw detector is a portable industrial non-destructive flaw detection instrument. It can quickly, conveniently, non-destructively and accurately detect, locate, evaluate and diagnose various defects (cracks, looseness, pores, inclusions, etc.) inside the workpiece. It can be used both in the laboratory and on the construction site.

[0003] Although the ultrasonic flaw detector in the prior art is small in size, it is still difficult to hold with one hand and has a large mass. Moving the flaw detector with one hand may cause the flaw detector to topple over or bump into something. During use, the staff generally needs one hand to control the probe and observe the waveform changes at the same time, and the other hand needs to operate the buttons to record the position of the defect wave. As the detection position changes, the distance between the probe and the flaw detector is often far, and the staff needs to open their arms to operate the buttons and the probe respectively, which is extremely inconvenient. During actual work, because the main body of the flaw detector is difficult to fix, it is generally placed on the ground. If the ground is uneven, the flaw detector cannot be placed steadily, which greatly troubles the normal work of the staff. Utility Model Content

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In the drawings, the same reference numerals all refer to the same components.

[0019] like Figure 1-2As shown, the utility model provides a digital ultrasonic flaw detector, including a device body 1, the device body 1 includes a main control block 2 and a base 3, a display screen 201 is arranged at one end of the main control block 2, a main control component is arranged inside the main control block 2, a base 3 is arranged at one end of the main control block 2, a detection component and an electromagnetic component are arranged inside the base 3, the detection component includes a probe 301, a connecting wire 3031 and a rotating column 303, the connecting wire 3031 is wound around the surface of the rotating column 303, and the electromagnetic component includes an iron core 305, a coil 304 and a power supply component.

[0020] The usage of the utility model is as follows:

[0021] 1. When using the device body 1, first take the device body 1 to the detection location, find an object that can be magnetically attracted, fit the base 3 and the object together, and then press the main control switch 202 to turn on the device body 1. After the device body 1 is turned on, the main control component controls the power supply component to turn on the power supply to the coil 304 and starts the telescopic component. After the power supply component supplies power to the coil 304, the iron core 305 acquires magnetism, and the device body 1 is magnetically fixed to the surface of the object through the electromagnetic component. After the telescopic component is started, the card block 302 is controlled to retract, and the limit of the probe 301 is cancelled. The staff takes the probe 301 out of the base 3, and uses the setting of the connecting line 3031 to perform ultrasonic flaw detection at a position far away from the device body 1;

[0022] 2. After the flaw detection is completed, the rotating column 303 is started by the button of the main control block 2. The rotating column 303 rotates to drive the connecting wire 3031, so that the connecting wire 3031 is recovered to the surface for winding. Finally, the probe 301 is reinserted into the base 3, and then the main control switch 202 is pressed to turn off the device body 1. After power is supplied, the electromagnetic component will quickly lose its magnetism.

[0023] Furthermore, a card slot is provided on the surface of one end of the probe 301, and a card block 302 is provided inside the base 3. The position and size of the card block 302 and the card slot correspond to each other. A telescopic component is provided at one end of the card block 302, and the telescopic component and the main control component are electrically connected. When the device body 1 is in a closed state, the card block 302 is in an extended state, and one end of the card block 302 is arranged inside the base 3 and the other end is arranged inside the card slot, thereby locking and fixing the probe 301 in the base 3. After the device body 1 is opened, the telescopic component controls the card block 302 to retract, and one end of the card block 302 leaves the card slot, and the probe 301 is unlocked.

[0024] Furthermore, a motor is provided in the rotating column 303, and a connecting line 3031 is connected to the probe 301, and the probe 301 is connected to the main control block 2 via the connecting line 3031. The staff can pull out the connecting line 3031 through the probe 301, so as to freely adjust the position of the probe 301. After use, the rotating column 303 is started by the switch on the main control block 2, and the rotating column 303 rotates to retract the connecting line 3031.

[0025] Furthermore, the coil 304 is wound around the surface of the iron core 305, and the two ends of the coil 304 are respectively connected to the positive and negative poles of the power supply component. The power supply component and the main control component are electrically connected. The coil 304 is wound around the surface of the iron core 305 and connected to the positive and negative poles of the power supply component. It is an electromagnet structure. When the power supply component supplies power to the coil 304, the iron core 305 will acquire magnetism. When the power supply component stops supplying power to the coil 304, the iron core 305 will lose its magnetism.

[0026] Furthermore, a main control switch 202 is provided at one end of the main control block 2 , and the main control switch 202 and the main control component are electrically connected. The main control switch 202 is used to control the startup and shutdown of the device body 1 .

[0027] The utility model is a digital ultrasonic flaw detector. By setting an electromagnetic component of an electromagnet structure, the device body 1 can be quickly fixed and disassembled by magnetic attraction, which is convenient for the work process of the staff. At the same time, the probe 301 is fixed by the clamping block 302 when the device body 1 is closed to prevent the probe 301 from falling.

[0028] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
