Description

TECHNICAL FIELD

[0001] The utility model relates to ultrasonic thickness measurement technical field, specifically for a kind of ultrasonic thickness measurement device for pipeline. BACKGROUND

[0002] The main purpose of pipeline thickness measurement is to monitor the wall thickness thinning degree caused by corrosion, wear and other factors during the use of pipeline, which is of great significance to ensure the safe operation of pipeline and prevent safety accidents such as leakage. By measuring the pipeline wall thickness regularly, potential safety hazards can be found in time and appropriate maintenance measures can be taken. In the process of pipeline thickness measurement, ultrasonic thickness gauge is often used. Its working principle is based on ultrasonic pulse reflection principle. When the ultrasonic pulse emitted by the probe reaches the material interface through the measured pipeline wall, the pulse is reflected back to the probe. By accurately measuring the time of ultrasonic propagation in the material and combining the propagation velocity of ultrasonic in the corresponding medium, the wall thickness of the measured pipeline can be calculated. However, the existing ultrasonic thickness gauge lacks effective protection structure around the probe during carrying by personnel. When the probe slips from the hand due to mistake, it is easy to collide directly with the ground and cause damage, affecting the subsequent thickness measurement by personnel and causing certain economic loss.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. This utility model, through the setting of the rubber protective sleeve, can effectively protect the sides and all four sides of the ultrasonic thickness gauge during use, preventing damage caused by drops and collisions. The hollow rubber protrusions and foam buffer blocks further enhance the impact buffer protection around the sides and all four sides of the ultrasonic thickness gauge, greatly reducing the impact of drops and collisions. Simultaneously, the fixing plate, protective cylinder, and rubber protective strips effectively store and protect the probe when not in use, preventing damage from collisions. Furthermore, the rubber protective sleeve, curved rubber strip, and buffer foam strips provide good impact protection around the probe during handling, preventing direct impact damage from drops, thus facilitating user operation.

[0014] 2. This utility model, through the provision of a first and second receiving groove, can accommodate the rotating shaft, rotating block, and winding rod. After use of the ultrasonic thickness gauge, personnel can pull the winding rod, causing it to rotate and extend to the right side of the ultrasonic thickness gauge. This facilitates the winding of the transmission line, preventing it from becoming tangled or knotted during placement due to its excessive length, thus improving convenience for subsequent use. Furthermore, the inclusion of receiving holes, pin grooves, pins, and support springs allows for appropriate application of force during the rotation of the winding rod, rotating shaft, and rotating block. The design reduces resistance and minimizes the chance of the ultrasonic thickness gauge's right-side rotation extending due to shaking during use. The groove design facilitates easy manipulation of the retractor stored in the second receiving slot. The anti-slip protrusions effectively improve the anti-slip effect of the docking interface surface, allowing for easier rotation. The acrylic protective plate provides effective protection in front of the ultrasonic thickness gauge's display screen, preventing direct impact damage and enhancing overall safety.

A probe 20 is fixedly installed at the right end of the transmission line 7. A fixing plate 19 is fixedly connected to the upper end of the probe 20. A protective cylinder 8 is threadedly connected to the surface of the fixing plate 19. A rubber protective strip 21 is fixedly connected to the outer surface of the protective cylinder 8.

Buffer foam strips 24 are filled between the surface of the arc-shaped rubber strip 22 and the surface of the rubber protective sleeve 23.

[0025] During use, the rubber protective sleeve 2 provides effective safety protection for the sides of the ultrasonic thickness gauge 1, preventing damage from drops and impacts. The hollow rubber protrusions 3 and foam buffer blocks further enhance impact protection, significantly reducing the impact of drops. The fixing plate 19, protective cylinder 8, and rubber protective strip 21 effectively store and protect the probe 20 when not in use, preventing damage from impacts.

[0026] like Figures 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a first receiving groove 11 is provided at the middle of the right side of the ultrasonic thickness gauge 1. Pin grooves 17 are provided around both sides of the first receiving groove 11. Second receiving grooves 13 are provided at both ends of the right side of the ultrasonic thickness gauge 1. A rotating shaft 12 is movably connected between the surface of the two second receiving grooves 13 and the surface of the first receiving groove 11. A winding rod 10 is fixedly connected to both sides of the rotating shaft 12. A rotating block 18 is fixedly connected to both ends of the winding rod 10. A receiving hole 14 is provided on the side of the two rotating blocks 18 that is far apart from each other. A pin 16 is movably connected between the surface of the receiving hole 14 and the surface of the pin groove 17. The surface of the pin 16... A support spring 15 is fixedly connected to the surface of the receiving hole 14. The surface of the winding rod 10 is movably connected to the surface of the second receiving groove 13. The surface of the rotating block 18 is movably connected to the surface of the first receiving groove 11. Grooves 9 are provided at both ends of the right side of the ultrasonic thickness gauge 1 and behind the second receiving groove 13. The grooves 9 are semi-circular in shape.

A control panel 4 is fixedly installed at the middle of the front surface of the ultrasonic thickness gauge 1.

[0027] Analysis of the above structure shows that, through the arrangement of the first receiving groove 11 and the second receiving groove 13, the rotating shaft 12, the rotating block 18, and the winding rod 10 can be accommodated. After use of the ultrasonic thickness gauge 1, personnel can pull the winding rod 10, causing it to rotate and extend to the right side of the ultrasonic thickness gauge 1. This facilitates the winding of the transmission line 7, preventing it from becoming tangled or knotted during placement due to its excessive length, thus improving convenience for subsequent use. Simultaneously, the arrangement of the receiving hole 14, the pin groove 17, the pin 16, and the support spring 15 allows the winding rod 10, the rotating shaft 12, and the rotating block 18 to rotate... Applying corresponding resistance during rotation reduces the likelihood of the ultrasonic thickness gauge 1 rotating and extending to the right due to shaking of the winding rod 10, rotating shaft 12, and rotating block 18 during use. The groove 9 facilitates the manipulation of the winding rod 10 stored in the second receiving groove 13. The anti-slip protrusions effectively improve the anti-slip effect of the docking interface 6 surface, making it easier for personnel to operate the docking interface 6 for rotation. The acrylic protective plate 5 provides effective protection in front of the display screen on the ultrasonic thickness gauge 1, preventing damage to the display screen due to direct impact, and effectively improving the overall safety protection effect.
