[0002] Smart grid, with its advantages of stability, high efficiency, low cost and low line loss, has become a key technical direction for improving the operation level of modern power systems. Among these technologies, the application of superconducting tapes is regarded as one of the core technologies of smart grids. Superconducting tapes have excellent current carrying capacity, which not only performs well in improving the safety and stability of power systems, but also shows unique advantages in power quality management, large-capacity long-distance power transmission and reducing grid losses. This makes superconducting tapes have wide application value and great development potential in the innovation of smart grids and power equipment. The application of superconducting tapes can significantly reduce the energy loss caused by resistance in traditional power grids and provide more efficient energy transmission solutions, especially playing a key role in the power supply network of large cities and industrial centers. In addition, superconducting technology also makes important contributions to the response to grid load fluctuations and the miniaturization and efficiency of power equipment.

[0003] However, during long-term current-carrying operation, superconducting tapes may develop micro-defects such as material stress concentration and local damage due to factors such as external environment and load changes. These defects may pose a hidden danger to the stable operation of the power system. Therefore, timely and effective detection and identification of potential defects in superconducting tapes has become an important issue to ensure the safe operation of the power system.

[0004] Therefore, there is an urgent need in the art for a superconducting tape detection device to solve the above problems. Summary of the invention

[0005] The present invention aims to solve the above technical problem, that is, to solve the problem of detecting defects in superconducting tapes.

[0006] In a first aspect, the present invention provides a superconducting tape detection device, the superconducting tape detection device comprising:

[0007] A conveying assembly, which is used to drive the superconducting tape to move;

[0008] A detection component includes a magnetizing component and a magnetic memory signal detection component, wherein the magnetizing component and the magnetic memory signal detection component are sequentially arranged along the moving direction of the superconducting tape, the magnetizing component can generate a magnetic field, and the magnetic field is used to magnetize the superconducting tape, and the magnetic memory signal detection component is used to detect the magnetic memory signal of the magnetized superconducting tape.

[0009] In a specific embodiment of the above-mentioned superconducting tape detection device, the superconducting tape detection device includes a plurality of the detection components, and the magnetic field characteristics generated by the magnetized parts of all the detection components are different, and the characteristics include at least one of the intensity, direction or frequency of the magnetic field.

[0010] In a specific implementation of the above-mentioned superconducting tape detection device, a plurality of the detection components are arranged in sequence along the moving direction of the superconducting tape.

[0011] In a specific implementation of the above-mentioned superconducting tape detection device, the magnetic field generated by the plurality of magnetized components includes a horizontal magnetic field and a vertical magnetic field, and the magnetic field direction of the horizontal magnetic field is arranged perpendicular to the magnetic field direction of the vertical magnetic field.

[0012] In a specific implementation of the above-mentioned superconducting tape detection device, the magnetic field generated by the plurality of magnetized components includes a DC magnetic field and an AC magnetic field.

[0013] In a specific embodiment of the above-mentioned superconducting tape detection device, the superconducting tape detection device further includes a demagnetizing component, which is arranged between two adjacent detection components and is used to eliminate the magnetizing effect of the magnetizing component on the superconducting tape.

[0014] In a specific embodiment of the above-mentioned superconducting tape detection device, the conveying assembly includes a first driving member, a driving wheel and a driven wheel, the superconducting tape to be detected is wound on the driven wheel, the end of the superconducting tape is connected to the driving wheel, the first driving member is connected to the driving wheel, the first driving member can drive the driving wheel to rotate, and when the driving wheel rotates, the superconducting tape can be driven to move from the driven wheel to the driving wheel.

[0015] In a specific implementation of the above-mentioned superconducting tape detection device, the first driving member can change the rotation speed of the driving wheel according to the detection frequency of the detection component.

[0016] In a specific embodiment of the superconducting tape detection device, a first pin is provided near the driving wheel, and the first pin abuts against the superconducting tape to put the superconducting tape in a tensioned state; and / or

[0017] A second pin is arranged near the driven wheel, and the second pin abuts against the superconducting tape to put the superconducting tape in a tensioned state.

[0018] In a specific embodiment of the above-mentioned superconducting tape inspection device, the conveying assembly further includes a belt-pressing wheel, which abuts against the superconducting tape and is used to guide the superconducting tape so that a portion of the superconducting tape passes through the inspection assembly.

[0019] In the case of adopting the above technical solution, the detection component of the present invention includes a magnetizing component and a magnetic memory signal detection component. The magnetizing component can apply a specific magnetic field to the superconducting tape, so that it produces a magnetization effect when passing through. The magnetic memory signal detection component is used to detect the magnetic memory signal generated on the magnetized superconducting tape. The conveying component can drive the superconducting tape to pass through the magnetizing component and the magnetic memory signal detection component in sequence. By analyzing the magnetic memory signal, stress concentration and potential defects in the tape can be quickly identified, and early warning and prevention can be achieved. This configuration improves the perception ability and detection sensitivity of the microstructure of the tape, allowing the system to more comprehensively characterize the quality of the tape. The system can timely locate and detect hidden dangers that affect performance, ensure reliability and stability under high load, and improve detection accuracy and consistency. The conveying component ensures the continuity and stability of the tape during the detection process, reduces deviation or interruption, and thus improves detection accuracy. The detection component can quickly analyze different positions of the tape, ensure the comprehensiveness of detection and improve the reliability of defect identification.

[0020] Furthermore, the superconducting tape detection device includes multiple detection components, and the magnetic field generated by the magnetized parts of each detection component is different. Magnetizing the superconducting tape with different magnetic fields can more comprehensively stimulate the tiny magnetic properties in the superconducting tape, improve the detection sensitivity and accuracy, and thus identify more subtle material defects or structural changes; different types of magnetic fields cause superconducting materials to produce different responses during the magnetization process, which helps to distinguish the details of the magnetic response, improve signal resolution and detection diversity; through magnetic fields of different strengths and directions, the magnetic properties of each region and microstructure of the superconducting tape can be revealed, which is convenient for comprehensively characterizing its magnetic memory properties and supporting material quality assessment, defect analysis and process optimization; multiple magnetization and signal recording reduce single measurement errors and improve the reliability and repeatability of detection results.

[0021] Furthermore, a demagnetizing piece is provided between the detection components, which can eliminate the influence of the previous magnetized piece on the superconducting tape so as not to affect the detection result of the next detection component. In this setting, each detection component can perform independent detection based on the state of the superconducting tape that is not affected by the residual magnetic effect of the previous stage during detection, ensuring that the results between different detection steps do not affect each other. This not only improves the accuracy of the detection, but also enables the detection system to perform multiple detections under multiple conditions more flexibly and obtain richer detection data. The configuration of the demagnetizing piece keeps the entire detection process coherent and accurate, while reducing the cumulative error caused by multiple magnetizations. This setting helps to optimize the defect identification and stress distribution analysis of superconducting tapes, ensure the reliability and stability of the detection results, and provide higher quality basic data for further analysis.

[0022] Furthermore, the conveying assembly includes a first driving member, a driving wheel and a driven wheel. The first driving member is connected to the driving wheel to accurately control the moving speed of the superconducting tape, thereby obtaining consistent and high-quality detection data. The combination of the driving wheel and the driven wheel can maintain appropriate tension of the tape, prevent relaxation or sliding, improve conveying stability, and adapt to long-term, continuous detection operations, thereby improving detection efficiency.

[0023] Furthermore, the first driving member can change the rotation speed of the driving wheel according to the detection frequency of the detection component, thereby controlling the moving speed of the superconducting tape. This setting method can dynamically match the conveying speed with the detection requirements, optimize the detection performance, and improve accuracy and reliability; it can also enhance the adaptability of the device, automatically adjust the rotation speed to save operating time, improve efficiency, and reduce human errors, ensuring stability and long-term reliability.

[0024] Furthermore, it ensures that it passes smoothly in the detection assembly. The configuration of the pinch wheel can effectively maintain the appropriate tension of the superconducting tape during transportation, thereby preventing it from shifting or relaxing during operation. This design optimizes the transportation effect, allowing the superconducting tape to maintain an accurate path and stable position when passing through the detection assembly, thereby avoiding data errors or detection instability caused by tape displacement during the detection process. By ensuring the smooth transportation of the tape, the pinch wheel improves the reliability and accuracy of the overall detection process. In addition, the role of the pinch wheel is not limited to tension control and preventing deviation. It can also enhance the contact consistency between the tape and the detection assembly and reduce errors caused by irregular movement during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The bottom plate 5 is used to support the conveying assembly and the detection assembly 1. In this embodiment, the bottom plate 5 is in the shape of a rectangular plate structure.

[0037] Regarding the shape of the bottom plate 5, it should be noted that although the shape of the bottom plate 5 in the present embodiment is a rectangular plate, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may also adopt other arrangements in other embodiments. For example, the bottom plate 5 may adopt a plate-like structure of other shapes such as a hexagon, an octagon, a circle, an ellipse, or the like. The bottom plate 5 may also adopt a non-plate-like structure such as a shell. These changes do not deviate from the basic principles of the present invention and therefore fall within the scope of protection of the present invention.

[0038] The conveying assembly is used to drive the superconducting tape 3 to move so that the superconducting tape 3 passes through the detection assembly 1. This arrangement realizes continuous conveying and detection of the superconducting tape 3, ensuring that the detection assembly 1 can detect different parts of the superconducting tape 3 efficiently and comprehensively.

[0039] The conveying assembly includes a driving wheel 201 , a driven wheel 202 and a belt-pressing wheel 203 .

[0040] The driving wheel 201 is connected to the first driving member, and the first driving member can drive the driving wheel 201 to rotate. The first driving member is specifically a motor, and the first driving member is fixedly arranged on the bottom plate 5. The superconducting tape 3 is connected to the driving wheel 201, and when the driving wheel 201 rotates, it can pull the superconducting tape 3 to move in the direction of the driving wheel 201. The combination of the driving wheel 201 and the driven wheel 202 can maintain appropriate tension of the tape, prevent relaxation or sliding, improve the transportation stability, and adapt to long-term, continuous detection operations, and improve detection efficiency. Furthermore, the first driving member can control the rotation speed of the driving wheel 201 according to the detection frequency of the detection component 1, and then control the moving speed of the superconducting tape 3. This setting method can dynamically match the conveying speed with the detection requirements, optimize the detection performance, and improve the accuracy and reliability; it can also enhance the adaptability of the device, automatically adjust the rotation speed to save operation time, improve efficiency, and reduce human errors, ensuring stability and long-term reliability.

[0041] The driven wheel 202 is rotatably connected to the bottom plate 5. The superconducting tape 3 to be detected is wound on the driven wheel 202, and when the driving wheel 201 rotates, the superconducting tape 3 can be moved from the driven wheel 202 to the driving wheel 201. The connection structure between the driven wheel 202 and the bottom plate 5 is as follows: a driven shaft 204 is fixedly provided on the bottom plate 5, and the driven wheel 202 is rotatably connected to the driven shaft 204. In one embodiment, the driven wheel 202 and the driven shaft 204 are connected through a bearing so that the driven wheel 202 can rotate around the driven shaft 204. In another embodiment, the driven wheel 202 is sleeved on the driven shaft 204, and the driven wheel 202 and the driven shaft 204 are clearance-matched so that the driven wheel 202 can rotate around the driven shaft 204.

[0042] Regarding the connection structure between the driven wheel 202 and the base plate 5, it should be noted that, although in the present embodiment a driven shaft 204 is fixedly provided on the base plate 5 and the driven wheel 202 is rotatably connected to the driven shaft 204, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may further adopt other arrangements in other embodiments, for example: the driven wheel 202 is fixedly connected to the driven shaft 204, the driven shaft 204 is rotatably connected to the base plate 5, the driven shaft 204 and the base plate 5 may be connected by bearings or by clearance fit, so that the driven wheel 202 and the driven shaft 204 can rotate relative to the base plate 5. These changes do not deviate from the basic principles of the present invention and therefore fall within the protection scope of the present invention.

[0043] The belt-pressing roller 203 is rotatably connected to the bottom plate 5. The belt-pressing roller 203 abuts against the superconducting tape 3 between the driving wheel 201 and the driven wheel 202 to form the superconducting tape 3 into a preset shape. In this embodiment, the superconducting tape detection device includes two belt-pressing rollers 203, which are respectively arranged on both sides of the detection component 1 to straighten the superconducting tape 3 between the two belt-pressing rollers 203 so that it passes through the detection component 1. The belt-pressing rollers 203 can also keep the superconducting tape 3 in tension, prevent deviation, and optimize the conveying effect and stability.

[0044] Regarding the number of the belt pressure rollers 203, it should be noted that although the number of the belt pressure rollers 203 in this embodiment is two, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may adopt other numbers in other embodiments according to the actual needs of the superconducting tape detection device. Such changes do not deviate from the basic principles of the present invention and therefore fall within the scope of protection of the present invention.

[0045] The connection structure between the belt-pressing wheel 203 and the bottom plate 5 is as follows: a connection shaft 205 is fixedly provided on the bottom plate 5, and the belt-pressing wheel 203 is rotatably connected to the connection shaft 205. In one embodiment, the driven wheel 202 is connected to the driven shaft 204 through a bearing, so that the driven wheel 202 can rotate around the driven shaft 204. In another embodiment, the driven wheel 202 is sleeved on the driven shaft 204, and the driven wheel 202 and the driven shaft 204 are in clearance fit, so that the driven wheel 202 can rotate around the driven shaft 204.

[0046] Regarding the connection structure between the belt pressure roller 203 and the base plate 5, it should be noted that although the base plate 5 in this embodiment is fixedly provided with a connecting shaft 205 and the belt pressure roller 203 can be rotatably connected to the connecting shaft 205, this arrangement is not a limitation of the present invention. Without departing from the principles of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, for example: the belt pressure roller 203 is fixedly connected to the connecting shaft 205, and the connecting shaft 205 can be rotatably connected to the base plate 5. The connecting shaft 205 and the base plate 5 can be connected by a bearing, or connected by a clearance fit, so that the belt pressure roller 203 and the connecting shaft 205 can rotate relative to the base plate 5. This does not deviate from the basic principles of the present invention and therefore falls within the protection scope of the present invention.

[0047] Furthermore, the belt-pressing wheel 203 can move relative to the bottom plate 5. When different types of superconducting tapes 3 are detected, the position of the belt-pressing wheel 203 can be adjusted to adjust the position of the superconducting tape 3 relative to the detection assembly 1, thereby ensuring the accuracy of the detection result; it can also keep the superconducting tape 3 in proper tension to avoid relaxation or deviation, thereby ensuring the accuracy and stability of the detection result. Figure 2, a slide groove 501 is provided on the bottom plate 5, the belt-pressing roller 203 is rotatably connected to the connecting shaft 205, the connecting shaft 205 is fixedly connected to the slider 6, and the slider 6 is movably connected to the slide groove 501. The belt-pressing roller 203 can rotate around the connecting shaft 205, and the slider 6 can move along the slide groove 501 to adjust the position of the belt-pressing roller 203. Furthermore, the slider 6 is connected to a second driving member, which is specifically an electric push rod, and the second driving member can drive the slider 6 to move along the slide groove 501.

[0048] It should be noted that, although the second driving member in this embodiment is an electric push rod, this arrangement is not a limitation of the present invention. Without departing from the principle of the present invention, those skilled in the art may also adopt other arrangements in other embodiments, for example: the second driving member is a motor, the motor is connected to the slider 6 through a lead screw mechanism, the rotation of the motor can drive the slider 6 to move along the lead screw, and can also accurately control the position of the slider 6. This does not depart from the basic principle of the present invention, and therefore falls within the scope of protection of the present invention.

[0049] Further, continue to refer to Figure 1 A first pin 701 is provided near the driving wheel 201 and the first belt-pressing roller 203 near the driving wheel 201. The first pin 701 abuts against the superconducting tape 3 between the driving wheel 201 and the first belt-pressing roller 203 to change the contact area between the superconducting material and the driving wheel 201, and the contact area between the superconducting tape 3 and the first belt-pressing roller 203, thereby reducing wear. A second pin 702 is provided near the driven wheel 202 and the second belt-pressing roller 203 near the driven wheel 202. The second pin 702 abuts against the superconducting tape 3 between the driven wheel 202 and the second belt-pressing roller 203 to change the contact area between the superconducting material and the driven wheel 202, and the contact area between the superconducting tape 3 and the second belt-pressing roller 203, thereby reducing wear.

[0050] The detection component 1 is used to detect the superconducting tape 3. The detection component 1 includes a magnetizing component 101 and a magnetic memory signal detection component 102. The magnetizing component 101 can simulate the earth's magnetic field to weakly magnetize the superconducting tape 3. The magnetic memory signal detection component 102 can detect the magnetic memory signal on the superconducting tape 3 that has been weakly magnetized, and the stress concentration area and defect area of ​​the superconducting tape 3 can be determined according to the magnetic memory signal. The magnetizing component 101 and the magnetic memory signal detection component 102 are arranged in sequence along the moving direction of the superconducting tape 3, so that the superconducting tape 3 is first magnetized by the magnetizing component 101 and then detected by the magnetic memory signal detection component 102.

[0051] Further, refer to Figure 3, the superconducting tape detection device can be provided with multiple detection components 1. The type of magnetic field generated by the magnetized component 101 of each detection component 1 is different. Among them, different types of magnetic fields refer to at least one of the characteristics of the magnetic field such as intensity, direction and frequency. In one embodiment, the multiple magnetic fields include a horizontal magnetic field and a vertical magnetic field, and the magnetic field direction of the horizontal magnetic field is set perpendicular to the magnetic field direction of the vertical magnetic field. Further, magnetic fields of multiple angles are set. In another embodiment, the multiple magnetic fields include a DC magnetic field and an AC magnetic field. Further, multiple AC magnetic fields of different frequencies are set.

[0052] The magnetic memory signal detection element 102 can detect the magnetic memory signal of the superconducting tape 3 after the most recent magnetization. Furthermore, a demagnetization element 4 is provided between the detection components 1, and the demagnetization element 4 can generate a magnetic field opposite to the magnetic field characteristics of the previous magnetization element 101, so as to eliminate the influence of the previous magnetization element 101 on the superconducting tape 3, so as not to affect the detection result of the next detection component 1. The advantages of this setting method are: different types of magnetic fields can more comprehensively excite the tiny magnetic characteristics in the superconducting tape 3, improve the detection sensitivity and accuracy, and thus identify more subtle material defects or structural changes; different types of magnetic fields cause superconducting materials to produce different responses during the magnetization process, which helps to distinguish the details of the magnetic response, improve the signal resolution and detection diversity; through magnetic fields of different strengths and directions, the magnetic characteristics of each region and microstructure of the superconducting tape 3 can be revealed, which is convenient for comprehensively characterizing its magnetic memory characteristics, and supports material quality assessment, defect analysis and process optimization; multiple magnetization and signal recording reduce single measurement errors and improve the reliability and repeatability of detection results.
