[0030] like Figure 1-Figure 5 As shown, the utility model provides a portable ultrasonic flaw detection device, which is used for ultrasonic flaw detection of steel plates.

[0031] In an exemplary embodiment, a portable ultrasonic flaw detection device comprises:

[0032] A main body 1, wherein a telescopic rod 2 is disposed inside the main body 1, and an extended end of the telescopic rod 2 passes through one end of the main body 1;

[0033] A holder is arranged at the extended end of the telescopic rod 2, the probe 10 is detachably connected to the holder, and a fixing mechanism for connecting the probe 10 is provided on the holder;

[0034] The water supply device 14 is arranged on the main body 1 and is used to keep the surface of the steel plate moist.

[0035] In this embodiment, by providing the main body 1 and the telescopic rod 2, the probe 10 can be fixed by the fixer at the end of the telescopic rod 2. After the fixation is completed, the length of the telescopic rod 2 is adaptively adjusted according to the height of the user. The user holds the main body 1 and moves it to drive the probe 10 to move quickly, thereby realizing efficient flaw detection of steel plates.

[0036] In this embodiment, the water supply device 14 is set up to continuously ensure that the steel plate at the inspection location remains moist during the movement of the probe 10. At the same time, in actual use of the present application, the main body 1 is moved by one hand, and the detector connected to the probe 10 is held with the other hand for observation. No two people are required to cooperate, which reduces the work intensity of the operators and improves the efficiency of a single person inspecting the steel plate.

[0037] In an exemplary embodiment, the fixer includes a first fixing block 3 , a second fixing block 4 and a connecting rod 5 for connecting the first fixing block and the second fixing block 4 , and the fixer is hinged to the output end of the telescopic rod 2 via the connecting rod 5 .

[0038] In this embodiment, the first fixing block 3 and the second fixing block 4 are hinged at the output end of the telescopic rod 2 through the connecting rod 5. When the probe 10 is not installed, the fixture can be flipped over to prevent the bottom of the first fixing block 3 and the second fixing block 4 from being damaged by contact with the ground when placed downward.

[0039] Exemplarily, in this embodiment, the rotation angle of the fixture is limited to within 180°.

[0040] It is worth noting that in the present embodiment, the telescopic rod 2 can be arranged in a variety of telescopic ways. Specifically, a sleeve with multiple sections of different diameters is used, and the length of the telescopic rod 2 is adaptively adjusted by manual pulling, similar to the structure of an umbrella rod, and a limiting element is provided to achieve a fixed length of the telescopic rod 2; an electric, startable, or hydraulic telescopic device can also be provided in the main body 1 to drive the telescopic rod 2 to automatically extend and shorten, so as to realize the telescopic function.

[0041] In an exemplary embodiment, the fixing mechanism includes a positioning rod 6 and a clamping piece, the positioning rod 6 is fixedly connected to the first fixing block 3 and extends toward the second fixing block 4, the clamping piece is threadedly connected to the second fixing block 4 and can approach or move away from the positioning rod 6, wherein the probe 10 can be rotatably connected to the clamping piece and the positioning rod 6.

[0042] Illustratively, in this embodiment, the probe 10 is provided with a first fixing hole 8 that can be plugged into the positioning rod 6, and the probe 10 is also provided with a second fixing hole 9 that can be plugged into the probe 10, and the axes of the first fixing hole 8 and the second fixing hole 9 are located on the same straight line.

[0043] In this embodiment, the probe 10 can be positioned by setting a fixing rod and a clamping rod 7 so that the probe 10 is installed on the fixture. After the positioning rod 6 is inserted into the first fixing hole 8 to achieve rough positioning of the probe 10, the clamping piece is screwed into the second fixing block 4, and its end moves toward the direction of the probe 10 and enters the second fixing hole 9, thereby achieving two-point positioning of the probe 10.

[0044] It is worth mentioning that in the present embodiment, after the positioning rod 6 and the clamping piece enter the first fixing hole 8 and the second fixing hole 9 respectively, since the axes of the first fixing hole 8 and the second fixing hole 9 are located on the same straight line, the probe 10 can rotate. When the steel plate is uneven, the probe 10 will rotate due to the action of gravity. Under the limiting action of the fixture and the steel plate, the contact degree between the probe 10 and the steel plate is better.

[0045] It should be further explained that the probe 10 in this embodiment includes a housing 1001 and a detection body 1002 disposed in the housing 1001 , and the first fixing hole 8 and the second fixing hole 9 are both provided on the housing 1001 .

[0046] In an exemplary embodiment, the water supplier 14 is detachably connected to the main body 1 , and a connecting pipe 15 is provided at the output end of the water supplier 14 . The connecting pipe 15 extends toward the probe 10 and is connected to the probe 10 .

[0047] In this embodiment, the water supply device 14 can keep the surface of the steel plate moist during the detection process of the probe 10, so that the ultrasonic detection can be carried out smoothly. When a single person performs the detection task, there is no need to add water to keep the entire steel plate moist before performing the detection, which optimizes the detection process and improves the detection efficiency.

[0048] Illustratively, in this embodiment, the water supply device 14 is mounted on the main body 1 in the form of a kit, and the connecting pipe 15 is detachably connected to the water supply device 14. The connecting pipe 15 is a hose. During use, a valve can be set at the output end of the water supply device 14, and a switch can be set on the main body 1. A certain amount of water can be discharged by pressing the switch, which can be freely selected by the operator.

[0049] Exemplarily, in this embodiment, the connecting tube 15 is connected to the probe 10. Specifically, it passes through the outer shell 1001, and the output end is located at the distance between the detection body 1002 and the outer shell 1001. In order to prevent the water flow from interfering with the detection body 1002, an isolation plate can also be set at the output end of the detection body 1002 and the connecting tube 15.

[0050] It is worth noting that in this embodiment, a positioning block 11 is provided on the first fixing block 3, and a positioning hole is provided on the positioning block 11, through which the connecting tube 15 passes to connect with the probe 10. The positioning hole provided on the positioning block 11 in this embodiment is used for positioning the connecting tube 15, and at the same time, since the connecting tube 15 is a hose, it is possible to avoid excessive bending and wear of the connection between the connecting tube 15 and the probe 10.

[0051] In an exemplary embodiment, a winding assembly is provided on the second fixed block 4, and the winding assembly includes a fixed plate 12 and a winding reel 13, the fixed plate 12 is fixedly connected to the second fixed block 4, and the winding reel 13 is fixedly connected to the fixed plate 12, and the winding reel 13 is used to accommodate the wires of the probe 10.

[0052] In this embodiment, the wire of the probe 10 can be placed by providing a winding assembly, thereby preventing the wire from being entangled during the flaw detection process and causing an impact on the operator.

[0053] Illustratively, in this embodiment, the winding reel 13 can also be configured as a winding group with a curling function, similar to the winding of fishing line on a fishing rod, so as to more conveniently realize the retraction and release of the wire of the probe 10.

[0054] In an exemplary embodiment, the bottoms of the first fixing block 3 and the second fixing block 4 are both arc-shaped.

[0055] In this embodiment, by setting the bottom of the first fixed block 3 and the second fixed block 4 to an arc shape, the contact area between the first fixed block 3 and the second fixed block 4 and the steel plate can be reduced, and the movement of the steel plate can be smoother in combination with the wet environment of the steel plate.

[0056] In an exemplary embodiment, a temperature sensor is disposed on the first fixing block 3 .

[0057] In this embodiment, the temperature sensor 17 is used to sense the temperature of the steel plate, and an alarm is triggered on the tester when the temperature is greater than 100° C. In this embodiment, the temperature of the flaw detection should not be greater than 100° C. Exceeding this range will affect the flaw detection results.

[0058] Exemplarily, the temperature sensor in this embodiment may also be replaced by a temperature gun that can detect the temperature.

[0059] In an exemplary embodiment, a scale 16 is provided on the telescopic rod 2 .

[0060] In this embodiment, a scale 16 is provided on the telescopic rod 2 to facilitate operators to measure defects during the flaw detection process without having to put down the entire device and use a tape measure for measurement, thereby improving the detection efficiency of the flaw detection.

[0061] In summary, the utility model can adapt to operators with different needs by means of the telescopic rod 2. At the same time, the main body 1 can drive the entire device to move, and the probe 10 can be installed through the fixer, which can conveniently realize steel plate flaw detection and improve the efficiency of steel plate flaw detection.

[0062] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
