Abstract
Description
Technical Field
[0001] This utility model relates to the field of ultrasonic testing auxiliary equipment technology, and in particular to an ultrasonic transducer fixing device used on a concrete wall. Background Technology
[0002] As a prestressed concrete structure, the stress state of the containment vessel changes due to prestress loss. Ultrasonic testing, as a non-destructive and rapid testing method, has become an important approach for assessing the stress state of the containment vessel. Because the containment vessel is a cylindrical structure with a steel lining, on-site testing can only use the planar measurement method. However, this method has two drawbacks: firstly, inconsistent transducer placement or fixing methods lead to significant fluctuations in test data; secondly, the actual propagation distance between transducers is difficult to determine accurately. Currently, no suitable fixing method has been found in engineering projects. Utility Model Content

[0018] Please see Figure 1 and Figure 2This is an ultrasonic transducer fixing device used on a concrete wall surface in some embodiments of the present utility model, which includes a transducer fixing bracket assembly 1, a transducer connecting plate 2, a transducer fixing component 3, a transducer positioning component 4, and a bracket fixing suction cup 5. The transducer mounting bracket assembly 1 includes a pair of transducer connecting brackets 11, which are detachably connected via a transducer connecting plate 2. Each transducer connecting bracket 11 has a U-shaped structure and a receiving space for accommodating an ultrasonic transducer 6. A transducer fixing member 3 is mounted on the transducer connecting bracket 11 and used to fix the relative position of the ultrasonic transducer 6 and the transducer connecting bracket 11. The transducer connecting bracket 11 has a through hole 111 for the transducer fixing member 3 to pass through. A transducer positioning member 4 is mounted on a concrete wall 7 and used to position the ultrasonic transducer 6. The transducer positioning member 4 has a positioning groove 41 for positioning the ultrasonic transducer 6. A bracket fixing suction cup 5 is connected to the transducer connecting plate 2 and adheres to the concrete wall 7. The positioning groove 41 is an arc-shaped groove adapted to the ultrasonic transducer 6.
[0019] Understandably, a pair of transducer connecting brackets 11 are detachably connected via transducer connecting plates 2, eliminating the need for integrated welding and facilitating device installation and position adjustment. The transducer connecting brackets 11 and the transducer positioning component 4 form a dual positioning system for the ultrasonic transducer 6, precisely constraining its installation position and limiting its movement to prevent displacement. The bracket fixing suction cup 5 enables rapid pre-fixation of the device to the concrete wall surface 7, eliminating the need for immediate gluing and allowing for final fixation after device position adjustment. This ultrasonic transducer fixing device, by integrating the transducer fixing bracket assembly 1, transducer connecting plate 2, transducer fixing component 3, transducer positioning component 4, and bracket fixing suction cup 5, achieves positioning, pre-fixing, and locking functions. The positioning groove 41 of the transducer positioning component 4 ensures precise positioning of the ultrasonic transducer 6, while the bracket fixing suction cup 5 provides initial pre-fixation, preventing device displacement before gluing and curing. The detachable transducer connecting plate 2 is designed to adapt to the installation requirements of ultrasonic transducers 6 of different specifications. This ultrasonic transducer fixing device can stably fit the curved surface of the concrete wall, significantly improving the positioning accuracy and fixing reliability of the ultrasonic transducer 6, ensuring that the ultrasonic transducer 6 is positioned consistently, thereby effectively improving the accuracy and reliability of ultrasonic pulse wave velocity measurement.
[0020] like Figure 2As shown, the transducer connecting bracket 11 has connecting sections 12 at both ends, which are used for adhesive bonding and fixation to the concrete wall surface 7. By providing connecting sections 12 at both ends of the transducer connecting bracket 11 and using adhesive bonding, the transducer connecting bracket 11 forms a surface contact fixation with the concrete wall surface 7, significantly increasing the contact area compared to point fixing. Combined with the pre-fixing effect of the bracket fixing suction cup 5, the transducer connecting bracket 11 can be prevented from shifting during the bonding process, significantly improving the overall fixing strength of the device and preventing loosening due to its own weight or external forces during long-term testing.
[0021] Furthermore, the connecting section 12 is provided with an vent 121, which is used to expel air during the gluing and fixing process. The vent 121 on the connecting section 12 can expel air between the transducer connecting bracket 11 and the concrete wall 7 during the gluing and fixing process, preventing air residue from forming air bubbles that would lead to insufficient curing of the adhesive. At the same time, by observing whether adhesive overflows from the vent 121, it is possible to visually determine whether the adhesive application is even and whether the pressing is in place, ensuring the consistency and reliability of the gluing quality.
[0022] The bottom of the connecting section 12 is provided with anti-slip texture, which increases the friction between the connecting section 12 and the concrete wall surface 7. Specifically, the anti-slip texture can be horizontal. The anti-slip texture on the bottom of the connecting section 12 further enhances the adhesion between the connecting section 12 and the concrete wall surface 7 by increasing the coefficient of friction of the contact surface. Before the adhesive cures, the anti-slip texture, together with the bracket fixing suction cup 5, achieves a dual anti-displacement effect, preventing the device from sliding before the adhesive has cured. After curing, it improves the shear resistance of the bracket, further ensuring the stability of the fixation.
[0023] The transducer connecting bracket 11 has a length of 80mm to 120mm, a height of 50mm to 70mm, and a connecting section 12 with a length of 10mm to 20mm. Preferably, the transducer connecting bracket 11 has a length of 96mm, a height of 60mm, and a connecting section 12 with a length of 15mm. The dimensions of this transducer connecting bracket 11 are compatible with the size specifications of mainstream ultrasonic transducers 6, while ensuring sufficient structural rigidity to avoid instability due to excessively small dimensions or increased installation burden due to excessively large dimensions. Furthermore, the transducer connecting plate 2 is made of 2mm thick 304 stainless steel plate, compatible with the transducer connecting bracket 11.
[0024] The transducer fixing component 3 is a fixing bolt, which is threadedly connected to the transducer connecting bracket 11. A buffer is provided between the transducer fixing component 3 and the surface of the ultrasonic transducer 6. Using a fixing bolt as the transducer fixing component 3, the threaded connection allows for adjustable locking force, accommodating ultrasonic transducers 6 of different thicknesses. The buffer can be a rubber pad. The buffer between the transducer fixing component 3 and the ultrasonic transducer 6 prevents excessive locking force from scratching the surface of the ultrasonic transducer 6. Simultaneously, elastic deformation compensates for the assembly gap between the transducer and the transducer connecting bracket 11, preventing minor vibrations of the ultrasonic transducer 6 during testing. This solves the problems of traditional rigid locking easily damaging the transducer and gaps causing inaccurate positioning.
[0025] The ultrasonic transducer fixing device also includes a connecting plate fixing component 8, which is used to fix the relative position of the transducer connecting plate 2 and the transducer connecting bracket 11. The connecting plate fixing component 8 can be a bolt, which can firmly lock the transducer connecting plate 2 and the transducer connecting bracket 11 to prevent relative displacement between the two during installation or testing.
[0026] The positioning groove 41 is equipped with a buffer pad to prevent damage to the ultrasonic transducer 6 from collision when it is placed in the positioning groove 41. At the same time, the elastic deformation of the buffer pad can adapt to the slight deviation of the transducer's shape, solving the problems of easy damage to the transducer and poor adaptability caused by hard contact positioning.
[0027] The ultrasonic transducer fixing device also includes a bubble level mounted on the transducer connecting bracket 11. The bubble level is used to detect the horizontal state of the transducer connecting plate 2 during device installation. The bubble level can detect the horizontal state of the transducer connecting plate 2 in real time during device installation, ensuring the stable installation of the ultrasonic transducer 6 and avoiding measurement errors of the ultrasonic transducer 6 caused by device tilt. Compared with manual visual leveling, this structure can control the levelness error within a smaller range, directly reducing the fluctuation of detection data caused by installation tilt and improving detection accuracy.
[0028] The ultrasonic transducer fixing device also includes an ultrasonic testing unit, which is used to perform data detection after the ultrasonic transducer 6 is fixed. Data detection can be performed directly after the ultrasonic transducer 6 is fixed, and the fixing effect can be verified by monitoring data fluctuations in real time from the unit. This avoids rework due to improper fixing and improves testing efficiency and data reliability.
[0029] The installation and usage procedure for the ultrasonic transducer fixing device is as follows: Preliminary positioning: Mark the preset position of the ultrasonic transducer 6 on the concrete wall 7, fix the transducer positioning part 4 to the marked position with AB glue, ensure that the center of the positioning groove 41 coincides with the marked point, and then put the ultrasonic transducer 6 into the positioning groove 41.
[0030] Bracket assembly: Align a pair of transducer connecting brackets 11 with the transducer connecting plate 2, and tighten them with the connecting plate fastener 8 to complete the assembly of the transducer fixing bracket assembly 1; attach the bubble level to the center of the surface of the transducer connecting plate 2.
[0031] Pre-fixing adjustment: Attach the assembled transducer fixing bracket assembly 1 to the wall surface, aligning the receiving space of the transducer connecting bracket 11 with the positioning groove 41 of the positioning component; press the bracket fixing suction cup 5 to make it adhere to the wall surface, and adjust the transducer fixing bracket assembly 1 to a horizontal state using a bubble level.
[0032] Adhesive fixing: Apply AB glue evenly to the wall surface of the connecting section 12, press the connecting section 12 onto the wall until glue overflows from the vent hole 121 to expel air, and let stand until the glue is completely cured.
[0033] Positioning of ultrasonic transducer 6: Coat the surface of ultrasonic transducer 6 with ultrasonic coupling agent, pass transducer fixing part 3 through the through hole 111 of the connecting bracket, so that the top of transducer fixing part 3 presses against ultrasonic transducer 6, and tighten transducer fixing part 3 to complete locking.
[0034] Testing and verification: Connect the ultrasonic transducer 6 to the ultrasonic testing instrument host, start the ultrasonic testing instrument host to perform data testing. If the data fluctuation is within 0.3μs, the fixation is deemed qualified; if the fluctuation exceeds the standard, fine-tune the fixing bolts and retest.
