Description

Technical Field

[0001] This utility model relates to the field of ultrasonic testing device technology, and in particular to an ultrasonic testing device for GIS metal particles using external impact vibration. Background Technology

[0002] In power systems, GIS, also known as gas-insulated metal-enclosed switchgear, is widely used due to its advantages such as small footprint, high reliability, and low maintenance workload. However, due to factors such as gas leakage, impurity intrusion, and insulator aging, flashover faults are prone to occur inside, seriously threatening the safe and stable operation of the power grid. GIS metal components are subjected to complex electrical and mechanical stresses and temperature and humidity environments for a long time, causing internal defects to gradually emerge and develop. Conventional detection methods are difficult to effectively detect early and subtle hidden dangers. External impact vibration combined with ultrasonic testing technology has emerged to address this issue. By applying impact vibrations of specific frequency and amplitude to the GIS metal, internal stress waves are stimulated to propagate. Ultrasonic testing devices receive the stress wave signals, and based on the signal characteristics, the location, size, and type of internal defects in the metal can be accurately identified, thereby assessing the operating status of the GIS. This technology overcomes the shortcomings of traditional detection methods, such as insensitivity to minute defects and limited detection range. It is of key significance for timely detection and handling of potential GIS faults, extending equipment lifespan, reducing the risk of power outages, and ensuring reliable power supply to the power system.

[0003] In existing ultrasonic testing of metal particles in GIS equipment, the traditional device has low fixation between the detection device and the GIS equipment shell, and the sensor installation pressure is difficult to adjust. If the pressure is too low, gaps may be generated, and if the pressure is too high, the sensor or equipment surface may be damaged. It is difficult to ensure a stable signal acquisition state, thus affecting the accuracy of the detection data.

[0004] To address this, an ultrasonic detection device for GIS metal particles using externally applied impact vibration is proposed. Utility Model Content

This makes it difficult to ensure a stable signal acquisition state, thereby affecting the accuracy of the test data.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-5 The present invention provides the following technical solution: An ultrasonic detection device for GIS metal particles using external impact vibration includes a data acquisition unit 1, an auxiliary structure 2 on the right side of the data acquisition unit 1, and a receiving sensor unit 3 attached to the inner side of the auxiliary structure 2. The auxiliary structure 2 includes a magnetic base 21, a mating block 22, a rotating rod 23, a threaded block 24, two fixed shells 25, two sliding pillars 26, a fixed rod 27, a stabilizing rod 28, and a pressure block 29. The top right side of the magnetic base 21 is fixedly connected to the bottom of the mating block 22. The inner wall of the mating block 22 is rotatably connected to the outer wall of the rotating rod 23. The outer wall of the rotating rod 23 is threadedly connected to the inner wall of the threaded block 24. The top left side of the magnetic base 21 is fixedly connected to the bottom of the fixed shell 25. The inner wall of the fixed shell 25 is slidably connected to the outer wall of the sliding pillar 26. The right side of the fixed rod 27 is bolted to the left side of the threaded block 24. The left side of the stabilizing rod 28 is fixedly connected to the right side of the sliding pillar 26. The right side of the pressure block 29 is bolted to the left side of the fixed rod 27. The left side of the pressure block 29 is bolted to the right side of the stabilizing rod 28. The bottom of the pressure block 29 is bolted to the top of the receiving sensor body 3.

[0019] In this embodiment: the data acquisition unit 1 is set as the core data processing component of the entire detection device, used to receive and process the ultrasonic signals collected by the receiving sensor unit 3. The receiving sensor unit 3 is set as the core component for collecting ultrasonic signals of GIS metal particles. An auxiliary structure 2 is set, in which the magnetic base 21 serves as the basic support component. It can be quickly and easily attached to the metal shell of the GIS equipment by the bottom magnetic force, realizing convenient fixation of the device. The mating block 22 is set to ensure that the rotating rod 23 does not shift during the rotation adjustment process. The rotating rod 23 can drive the threaded block 24 to move up and down by rotating, converting the rotational motion into the linear motion of the threaded block 24, realizing the position adjustment of the pressure block 29, and thus adjusting the installation pressure of the receiving sensor unit 3. The threaded block 22 is set. 4. The fixed housing 25 is used to move up and down under the drive of the rotating rod 23, and serves to connect the rotating rod 23 and the fixed rod 27. The fixed housing 25 is used to provide a sliding track and support for the sliding column 26. The sliding column 26 is used to drive the stabilizing rod 28 to move when sliding in the fixed housing 25, which enhances the movement stability of the stabilizing rod 28 and the pressure block 29 and prevents the pressure block 29 from shaking during the adjustment process. The fixed rod 27 is used to transmit the moving force of the threaded block 24 to the pressure block 29. The stabilizing rod 28 is used to assist in stabilizing the movement of the pressure block 29 and forms multi-sided support with the fixed rod 27. The pressure block 29 is used to fix the receiving sensor body 3 and adjust its installation pressure. The pressing force on the receiving sensor body 3 can be adjusted by moving up and down to ensure that the receiving sensor body 3 is in close contact with the detection surface and reduce the ultrasonic signal transmission loss.

[0020] Specifically, such as Figure 5 As shown, a mounting component 4 is bolted to the rear side of the data acquisition instrument body 1, a rotating component 5 is hinged to the inner wall of the mounting component 4, and a support block 6 is bolted to the bottom of the rotating component 5.

[0021] Specifically, such as Figure 2 , Figure 3 As shown, the top of the fixed shell 25 is provided with a mating groove 7, and the stabilizing rod 28 is disposed inside the mating groove 7.

[0022] Specifically, such as Figure 2 As shown, the top of the pressure block 29 is provided with a mating hole 8, the inner wall of the mating hole 8 is in contact with the top of the outer wall of the receiving sensor body 3, and the wiring terminal of the receiving sensor body 3 passes through the mating hole 8.

[0023] In this embodiment: by setting the mounting part 4, the rotating part 5 and the support block 6, auxiliary support is provided for the data acquisition instrument body 1. The support angle of the support block 6 can be adjusted by the rotating part 5 so that the data acquisition instrument body 1 can be stably placed on the desktop or other flat surface. The mating groove 7 opened by the fixed shell 25 is used to guide and limit the movement of the stabilizing rod 28. The mating hole 8 opened by the pressure block 29 is used to provide a passage for the wiring terminal of the receiving sensor body 3.

[0024] Specifically, such as Figure 2 As shown, the bottom of the magnetic base 21 is provided with an installation groove 9, and the inner wall of the installation groove 9 is provided with magnetic blocks 10, and the number of magnetic blocks 10 is three.

[0025] Specifically, such as Figure 1 , Figure 3 , Figure 4 As shown, a limiting plate 11 is bolted to the top of the fixed shell 25, and the bottom of the limiting plate 11 contacts the top of the sliding column 26.

[0026] In this embodiment: by setting the mounting slot 9 of the magnetic base 21 and setting three magnetic blocks 10, the magnetic base 21 and the GIS equipment are quickly fixed by magnetic force. The multiple magnetic blocks 10 are distributed to enhance the adsorption force and ensure that the device will not fall off during the detection process. The limiting plate 11 is set to limit the top of the sliding column 26.

[0027] Specifically, such as Figure 2 As shown, the top of the threaded block 24 is provided with a threaded hole 12, and the inner wall of the threaded hole 12 is threadedly connected to the outer wall of the rotating rod 23.

[0028] Specifically, such as Figure 1 , Figure 3 , Figure 5 As shown, the top of the rotating rod 23 is fixedly connected to an anti-slip torsion member 13, and the bottom of the anti-slip torsion member 13 is movably connected to the top of the threaded block 24.

[0029] In this embodiment: the threaded hole 12 opened by the threaded block 24 provides a threaded channel for the cooperation between the rotating rod 23 and the threaded block 24. The anti-slip torsion member 13 is provided to provide a convenient grip adjustment part for the rotating rod 23. Its outer wall has an anti-slip setting to increase the friction of the hand, so that the operator can easily and effortlessly rotate the rotating rod 23.

[0030] Working Principle: When the device is used to inspect GIS equipment, it first generates magnetic force through the magnetic block 10 at the bottom of the magnetic base 21 in the auxiliary structure 2, which quickly and firmly attaches the device to the metal shell of the GIS equipment, achieving stable fixation of the inspection position. The operator rotates the rotating rod 23 through the anti-slip torsion member 13. The rotating rod 23 rotates under the support of the mating block 22. Its outer wall thread engages with the threaded hole 12 of the threaded block 24, causing the threaded block 24 to move up and down. When the threaded block 24 moves, it pushes the pressure block 29 through the fixing rod 27. At the same time, the sliding column 26 slides in the fixed shell 25, causing the stabilizing rod 28 to assist the pressure block 29 to move smoothly. The mating groove 7 limits the stabilizing rod 28 to ensure that the pressure block 29 does not deviate during movement. The installation pressure of the receiving sensor body 3 is adjusted by moving it downwards to ensure close contact with the detection surface of the GIS equipment, reducing ultrasonic signal transmission loss. The hole 8 provides a passage for the wiring terminal of the receiving sensor body 3. When the GIS equipment is subjected to external impact and vibration, the internal metal particles move and generate ultrasonic signals. The receiving sensor body 3 collects the signal and transmits it to the data acquisition instrument body 1 through the wiring terminal. The data acquisition instrument body 1 processes and analyzes the received ultrasonic signal to complete the detection of metal particles. During the detection process, the auxiliary support structure composed of the mounting part 4, the rotating part 5, and the support block 6 can adjust the placement angle of the data acquisition instrument body 1 to ensure its stable placement. The limiting plate 11 prevents the sliding column 26 from detaching from the top of the fixed shell 25, ensuring the overall structural stability.

[0031] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
