DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example 1:

[0033] See also Figures 1 to 4 , which shows an example of the construction of a high-reliability nondestructive flaw detector given in this example.

[0034] The high-reliability nondestructive flaw detector is specifically composed of a flaw detector body 1, a display 2, and control buttons 3. The display 2 and control buttons 3 are provided on the upper surface of the flaw detector body 1, a strap 4 is provided on the left side of the flaw detector body 1, an anti-slip pad 5 is provided at the front end of the flaw detector body 1, and a handle assembly 6 is provided on the outside of the flaw detector body 1.

[0035] In some embodiments of this example, the flaw detector body 1 of the nondestructive flaw detector utilizes straight, oblique, dual-crystal, and through-hole probes. The flaw detector body 1 has a detection range of 0.0 mm to 6000.0 mm, and a thickness of 40 mm to 45 mm. This configuration allows the flaw detector body 1 to be equipped with a variety of flaw detection probes capable of measuring material thickness and sound velocity. Multiple flaw detection processes and standards are automatically generated, allowing for the free configuration of flaw detection process standards for various industries. On-site flaw detection eliminates the need to carry test blocks, and the flaw detector body 1 is thin, lightweight, and easily portable.

[0036] In some embodiments of this example, the flaw detector body 1 of the nondestructive flaw detector is internally equipped with dual CPUs, with the instrument control and data processing functions operating independently. The gain range of the flaw detector body 1 is 0dB to 110dB. This configuration utilizes an industrial-control CPU system, with dual CPUs working in tandem and the instrument control and data processing functions operating independently. This system operates at high speed and reliability, offering excellent field performance and robust data processing capabilities. The flaw detector body 1 also features high sensitivity, a gain of up to 110dB, and adjustable echo suppression without affecting instrument gain or linearity, ensuring high reliability.

[0037] It should be noted that the CPU model installed in the flaw detector body 1 and the control mechanism for achieving dual CPU collaboration based on the dual CPUs are not limited here and can be determined according to actual needs. By way of example, an existing stable and reliable implementation solution can be used. This is a well-known technology to those skilled in the art and will not be described in detail here.

[0038] In some embodiments of this example, the nondestructive flaw detector's display 2 is a 320×240 true-color display, and the control buttons 3 are a full-Chinese keyboard. This configuration allows the display 2 to display in full Chinese true-color, offering high clarity, a wide viewing angle, and immunity to electromagnetic interference. Even in strong sunlight, satisfactory observation results can be achieved without a sunshade. The fully Chinese control buttons 3 are intuitive and easy to remember, and the fully Chinese operating instructions are easy to understand and use.

[0039] Example 2:

[0040] This example further provides an improved solution based on the solution in Example 1.

[0041] In this example, improvements are made specifically to the structure of the handle assembly 6 in Example 1.

[0042] like Figure 5 As shown, the handle assembly 6 given in this example includes a first fixing seat 601, a handle body 602, a rubber strip 603, a fixing groove 604, a second fixing seat 605, a first groove 606, a sliding rod 607, a limiting ring 608, a rotating seat 609, a second groove 610, a locking plate 611, a limiting plug 612, a knob 613 and a screw 614.

[0043] Among them, the outer side of the first fixed seat 601 is rotatably connected to the handle body 602, the rear end of the handle body 602 is fixedly connected to the rubber strip 603, the front end of the handle body 602 is provided with a fixing groove 604, the inner side of the handle body 602 is provided with a second fixed seat 605, the outer side of the second fixed seat 605 is provided with a first groove 606, the outer side of the second fixed seat 605 is fixedly connected to a slide rod 607, the outer side of the second fixed seat 605 is provided with a limiting ring 608, the front end of the handle body 602 is fixedly connected to a swivel seat 609, the inner side of the swivel seat 609 is provided with a second groove 610, the inside of the swivel seat 609 is provided with a locking plate 611, the inner side of the locking plate 611 is provided with a limiting plug 612, the outer side of the swivel seat 609 is provided with a knob 613, and the inner side of the knob 613 is fixedly connected with a screw 614.

[0044] On this basis, in this example, the anti-slip pad 5 and the rubber strip 603 are made of nitrile rubber, and the cross-section of the rubber strip 603 is a semicircular structure. Advantageously, the provision of the anti-slip pad 5 and the rubber strip 603 allows the flaw detector body 1 to be tilted when in use. The handle assembly 6 provides support for the flaw detector body 1, and the anti-slip pad 5 and the rubber strip 603 contact the placement surface, thereby improving the stability of the flaw detector body 1, enhancing its reliability, and preventing it from tipping over.

[0045] As a further improvement, the second fixing seat 605 in this embodiment is rotatably connected to the rotating seat 609 via a limiting ring 608. The first groove 606 and the second groove 610 have the same size and structure. The limiting plug 612 has an inclined surface on the end away from the locking plate 611. The limiting plug 612 is adapted to both the first groove 606 and the second groove 610. With this arrangement, when the handle assembly 6 is in use and the flaw detector body 1 needs to be hung, the handle body 602 is rotated until it is parallel to the flaw detector body 1. The knob 613 is turned to rotate the screw 614, which in turn drives the threaded locking plate 611 to move along the slide bar 607. During this process, the limiting plug 612 is inserted into the second groove 610 and the first groove 606, locking the rotating seat 609 and the second fixing seat 605, thereby locking the handle assembly 6 in position. The fixing groove 604 of the handle body 602 is then hung on a hook or other protrusion on the wall for stable suspension.

[0046] As a further improvement, in this embodiment, the screw 614 is rotatably connected to the second fixing seat 605, the screw 614 is threadedly connected to the locking plate 611, and the locking plate 611 is slidably connected to the slide bar 607. With this arrangement, when the flaw detector body 1 needs to be tilted, the handle body 602 is rotated to an appropriate angle, and the knob 613 is turned to rotate the screw 614. The rotation of the screw 614 drives the threaded locking plate 611 to move along the slide bar 607. During this process, the inclined surface of the limit block 612 contacts the second groove 610, thereby guiding the limit block 612 to insert into the second groove 610 and the first groove 606, locking the rotating seat 609 with the second fixing seat 605, thereby limiting and locking the handle assembly 6. The flaw detector body 1 is then placed on a placement surface. At this time, the anti-slip pad 5 and the rubber strip 603 are in contact with the placement surface, ensuring stable placement and facilitating the observation of flaw detection data.

[0047] In order to further illustrate the structure and characteristics of the high-reliability non-destructive flaw detector provided by the present invention, the application process is described below in combination with its structure.

[0048] Combine Figures 1 to 5 The flaw detector body 1 in this high-reliability nondestructive flaw detector is equipped with a variety of flaw detection probes, which can measure material thickness and material sound velocity. A variety of flaw detection processes and flaw detection standards are automatically generated, and the flaw detection process standards of various industries can be freely set. There is no need to carry test blocks for on-site flaw detection. The flaw detector body 1 is thin and light, and is easy to carry.

[0049] The flaw detector body 1 adopts an industrial control CPU system. The instrument control part and data processing work independently. The system runs at high speed and reliability, with excellent on-site performance and strong data processing capabilities. The flaw detector body 1 has high sensitivity, a gain of 110dB, and adjustable echo suppression without affecting the instrument gain and linearity, making it very reliable. The display 2 is a full-Chinese true color display with high clarity and wide viewing angle. It is not affected by electromagnetic fields and can achieve satisfactory observation effects without a sunshade in strong sunlight. The control buttons 3 are all in Chinese and are intuitive and easy to remember. The operation prompts are all in Chinese, easy to master and convenient to use.

[0050] When using, if the flaw detector body 1 needs to be hung, rotate the handle body 602 until it is parallel to the flaw detector body 1, turn the knob 613 to drive the screw 614 to rotate, and the rotation of the screw 614 drives the threaded locking plate 611 to move along the slide bar 607. During this process, the limiting plug 612 is inserted into the second groove 610 and the first groove 606, locking the rotating seat 609 and the second fixing seat 605, thereby limiting and locking the handle assembly 6, and hanging the fixing groove 604 of the handle body 602 on a hook or other protrusion on the wall for stable hanging.

[0051] When the flaw detector body 1 needs to be tilted, the handle body 602 is rotated to an appropriate angle, and the knob 613 is turned to drive the screw 614 to rotate. The rotation of the screw 614 drives the threaded locking plate 611 to move along the slide rod 607. During this process, the inclined surface of the limit plug 612 contacts the second groove 610, thereby guiding the limit plug 612 to be inserted into the second groove 610 and the first groove 606, locking the swivel seat 609 with the second fixed seat 605, thereby limiting and locking the handle assembly 6, and placing the flaw detector body 1 on the placement surface. At this time, the anti-slip pad 5 and the rubber strip 603 are in contact with the placement surface, and the placement is stable, which is convenient for observing the flaw detection data.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
