[0002] The loop main pipelines used in nuclear power plants are mostly cast from austenitic stainless steel, and are mainly used to transport the coolant carrying huge heat in the reactor pressure vessel to the evaporator for heat exchange with the secondary loop coolant. In order to ensure the stable operation of the equipment, it is necessary to regularly perform ultrasonic detection on the welds of austenitic stainless steel cast pipelines to avoid leaks and other dangers at the welds after long-term use.

[0003] At present, commonly used ultrasonic detection equipment consists of an annular bracket and multiple ultrasonic probes arranged on the annular bracket. When in use, the annular bracket is surrounded by the outside of the pipeline, and the multiple ultrasonic probes are placed against the outer surface of the pipeline to perform ultrasonic detection.

It is impossible to detect weld defects in the main pipeline in time, and there is a safety hazard. Summary of the invention

[0060] An embodiment of the present application provides a highly integrated pipeline ultrasonic detection disc for ultrasonic detection of pipelines. Figure 1 This is a schematic diagram of the structure of a highly integrated pipeline ultrasonic detection disk in an embodiment of the present application. Figure 1 The state shown is the horizontal posture of the highly integrated pipeline ultrasonic detection disc in the embodiment of the present application, which can perform ultrasonic detection operations on vertically arranged pipelines. The highly integrated pipeline ultrasonic detection disc can also be in a vertical posture to perform ultrasonic detection operations on horizontally arranged pipelines; or in an inclined posture to perform ultrasonic detection operations on inclinedly arranged pipelines.

[0061] like Figure 1 As shown, the highly integrated pipeline ultrasonic detection disc provided in the embodiment of the present application includes a disc body assembly 100 and a probe assembly 200 disposed on the disc body assembly 100. The number of the probe assemblies 200 can be arbitrary, and in the present embodiment, the number of the probe assemblies 200 is multiple.

[0062] The disc assembly 100 is used to support the probe assembly 200. When in use, the disc assembly 100 is wrapped around the outside of the pipe to be tested, so as to support the probe assembly 200 at the pipe to be tested for ultrasonic detection. It is understood that the shape of the disc assembly 100 can be arbitrary and can be adapted to the shape of the pipe to be tested. Figure 2As shown, in this embodiment, the disc assembly 100 is arc-shaped, and a plurality of probe assemblies 200 are arranged at intervals along the circumference of the disc assembly 100 .

[0063] like Figure 3 As shown, the tray assembly 100 may include a first curved plate 110, a second curved plate 120 and a plurality of curved side plates 130. Figure 1 In the state shown, the first curved plate 110 and the second curved plate 120 are both horizontally arranged, the first curved plate 110 is located above the second curved plate 120, and a plurality of curved side plates 130 are vertically arranged and spaced between the first curved plate 110 and the second curved plate 120, wherein the first curved plate 110, the second curved plate 120 and two adjacent curved side plates 130 enclose an installation cavity 101. In addition, the disk assembly 100 further includes two end plates 140, which are respectively connected to the two ends of the first curved plate 110 and the second curved plate 120 to close the two side openings of the installation cavity 101.

[0064] It is understandable that the components in the disk assembly 100 may be integrally formed, or may be separately manufactured and then connected to each other by bonding, clamping, or fastener connection. In this embodiment, the second curved plate 120 and the plurality of curved side plates 130 are integrally formed, and the first curved plate 110 and the two end plates 140 are connected to the plurality of curved side plates 130 and the second curved plate 120 by screws.

[0065] The tray assembly 100 can be made of lightweight materials such as aluminum alloy, and through holes can be provided on the first curved plate 110, the second curved plate 120 and the curved side plate 130 to further reduce the weight of the tray assembly 100 and achieve the purpose of lightweighting.

[0066] The probe assembly 200 includes: a support component 210, a probe component 230 and an elastic component 240. The support component 210 is connected to the disc assembly 100, the probe component 230 is slidably disposed on the support component 210 along a first direction, and the probe component 230 has a detection surface 2331 facing away from the first direction, and the elastic component 240 is disposed between the probe component 230 and the support component 210, and is used to apply an elastic force facing away from the first direction to the probe component 230. In this embodiment, the disc assembly 100 is arc-shaped, and the first direction may be the radial direction of the disc assembly 100, that is, the probe component 230 may slide along the radial direction of the disc assembly 100, and the detection surface of the probe component 230 faces the axial direction of the disc assembly 100.

[0067] like Figure 4 , Figure 5 and Figure 6As shown, in this embodiment, the support component 210 includes a first support frame 211 and a slider 212. The first support frame 211 has a first connecting portion 211a and a second connecting portion 211b that are perpendicular to each other, and the first connecting portion 211a and the second connecting portion 211b are respectively abutted against the second arc plate 120 and the outermost arc side plate 130 surface of the disc assembly 100. Two positioning pins 121 are provided at the bottom of the second arc plate 120, and the first connecting portion 211a is provided with two positioning holes, and the two positioning pins 121 are respectively penetrated in the two positioning holes. The outermost arc side plate 130 is provided with a double-ear bolt 131 connected by threading, and the second connecting portion 211b is provided with a through hole, and the double-ear bolt 131 is penetrated in the through hole. Therefore, the probe assembly 200 can be installed on the disc assembly 100 by the double-ear bolt 131 and the positioning pin 121, and it is easy to disassemble. The sliding block 212 is disposed on a side of the first connecting portion 211 a away from the second arc-shaped plate 120 , and a sliding groove opened along the first direction may be disposed on the sliding block 212 .

[0068] In some embodiments, the probe assembly 200 may further include a slide rail 220, the slide rail 220 is arranged along the first direction, the probe component 230 is arranged on the slide rail 220, and the elastic component 240 is arranged between the slide rail 220 and the support component 210. The slide rail 220 is embedded in the slide groove of the slider 212 to enable the probe component 230 to slide relative to the disc assembly 100 in the first direction.

[0069] When in use, the disc assembly 100 is wrapped around the outside of the measured pipe, and at the same time, a thrust is applied to the disc assembly 100 in the direction of the measured pipe, so that the detection surface 2331 in the probe component 230 is against the outer surface of the measured pipe. Under the action of the slide rail 220, the disc assembly 100 can slide relative to the probe component 230 in the direction of the measured pipe. At this time, the elastic component 240 accumulates force and uses the elastic force to provide a thrust to the slide rail 220 and the probe component 230 in the direction of the outer surface of the measured pipe, thereby ensuring that the detection surface 2331 is in close contact with the outer surface of the measured pipe, thereby improving the detection accuracy.

[0070] like Figure 5 and Figure 6 As shown, in some embodiments, the elastic component 240 includes a first mounting bracket 241, a roller 242 and a coil spring 243. The first mounting bracket 241 is connected to the slide rail 220, the roller 242 is rotatably disposed on the first mounting bracket 241, the coil spring 243 is wound around the roller 242, and the free end of the coil spring 243 is connected to the support component 210.

[0071] When a thrust is applied to the disc assembly 100 toward the direction of the measured pipeline during ultrasonic detection, the slide rail 220 and the probe component 230 move relative to the disc assembly 100 toward the outside of the disc assembly 100, and push the first mounting bracket 241 and the roller 242 to move away from the support component 210. Since the free end of the coil spring 243 is fixed on the support component 210, the vortex-wrapped coil spring 243 unfolds from the roller 242 when the roller 242 rotates, causing the coil spring 243 to deform and store force. After storing force, the coil spring 243 has an elastic force that contracts toward the roller, thereby generating a pulling force to pull the roller 242 to restore its initial position, thereby applying a thrust toward the measured pipeline to the slide rail 220 and the probe component 230.

[0072] The first mounting bracket 241 can be fixed to the end of the slide rail 220 away from the probe component 230 by fasteners such as screws, and the free end of the coil spring 243 can also be fixed to the support component 210 by fasteners and other structures. In this embodiment, the support component 210 also includes a pressing block 213, and the pressing block 213 is arranged on the first support frame 211. The pressing block 213 can be fixed to the first connecting portion 211a of the first support frame 211 by screws, and the free end of the coil spring 243 can be pressed between the pressing block 213 and the first connecting portion 211a, and the free end is fixed to the first support frame 211 by the pressing block 213.

[0073] In some embodiments, a connecting hole 2431 may be further provided at the free end of the coil spring 243 , and a positioning column 2111 is provided at a portion of the first support frame 211 facing the pressing block 213 , and the positioning column 2111 passes through the connecting hole 2431 .

[0074] like Figure 6 As shown, a positioning column 2111 perpendicular to the first connecting portion 211a of the first support frame 211 is provided on the surface thereof. The connecting hole 2431 of the free end of the coil spring 243 can be firstly sleeved on the positioning column 2111, and then the free end can be pressed by the pressing block 213, so as to ensure that the free end of the coil spring 243 is not easy to fall out from between the pressing block 213 and the first support frame 211.

[0075] In addition, the elastic component 240 can also be a coil spring or elastic material connected to the slide rail 220. When the probe component 230 moves toward the disk assembly 100, the coil spring or elastic material is compressed, which can also generate a thrust to move the probe component 230 toward the measured pipeline.

[0076] like Figure 6 and Figure 7As shown, in some embodiments, the probe component 230 includes: a second mounting bracket 231, a second support frame 232, and an ultrasonic probe 233. The second mounting bracket 231 is connected to the slide rail 220, the second support frame 232 is provided with a connecting shaft 2321, and is rotatably connected to the second mounting bracket 231 through the connecting shaft 2321, the ultrasonic probe 233 is provided on the second support frame 232, and the side of the ultrasonic probe 233 facing away from the disc assembly 100 is a detection surface 2331.

[0077] The structure of the second mounting bracket 231 can be arbitrary, and the second mounting bracket 231 can be connected to the end of the slide rail 220 facing the inner side of the disk assembly 100 by fasteners such as screws. Figure 7 In the state shown, the second mounting bracket 231 may be provided with a vertical mounting hole for the connecting shaft 2321 to penetrate.

[0078] Similarly, the structure of the second support frame 232 can also be arbitrary. In this embodiment, the second support frame 232 has a receiving cavity, and the ultrasonic probe 233 is installed in the receiving cavity. The connecting shaft 2321 is arranged on the top of the second support frame 232, and the connecting shaft 2321 is passed through the mounting hole of the second mounting bracket 231, so that the ultrasonic probe 233 is installed below the slide rail 220. In addition, Figure 1 As shown, the connecting shaft 2321 can also be arranged at the bottom of the second support frame 232, and the accommodating cavity opening of the second support frame 232 is arranged upward to support the ultrasonic probe 233 on the upper side of the slide rail 220. It can be understood that each probe component 230 may include one or more ultrasonic probes 233, such as Figure 7 As shown, when the probe component 230 has two ultrasonic probes 233 , the first support frame 211 may be provided with two accommodating cavities to respectively install the two ultrasonic probes 233 .

[0079] By rotating the second support frame 232 and the ultrasonic probe 233 around the axis of the connecting shaft 2321, the ultrasonic probe 233 can adapt to the deflection according to the shape of the outer surface of the measured pipe during the ultrasonic detection process, further improving the fit between the detection surface 2331 and the outer surface of the measured pipe.

[0080] Recombination Figure 8 , Fig. 9 and Fig.10As shown, in some embodiments, the second mounting bracket 231 is respectively provided with a first limiting surface 2311 and a second limiting surface 2312 on opposite sides of the connecting shaft 2321. The second support frame 232 is respectively provided with a first limiting column 2322 and a second limiting column 2323 on opposite sides of the connecting shaft 2321. The second support frame 232 rotates around the axis of the connecting shaft 2321 to have a first limit position where the first limiting column 2322 abuts against the first limiting surface 2311, and a second limit position where the second limiting column 2323 abuts against the second limiting surface 2312.

[0081] like Fig. 9 and Fig.10 As shown, when the ultrasonic probe 233 is deflected to the first limit position or the second limit position around the connecting shaft 2321, it is restricted and cannot continue to rotate, so that the ultrasonic probe 233 can be properly deflected according to the shape of the surface of the measured pipe, and will not rotate significantly due to the thrust generated by the elastic component 240. By limiting the maximum deflection angle of the ultrasonic probe 233, it is ensured that the detection surface 2331 of the ultrasonic probe 233 is stably attached to the surface of the measured pipe.

[0082] In this embodiment, the second mounting bracket 231 is provided with arc grooves on both sides opposite to the connecting shaft 2321, and the first limiting surface 2311 and the second limiting surface 2312 are the inner walls of the arc grooves on both sides. The first positioning column 2111 and the second positioning column 2111 are both cylinders built into the arc grooves, and the diameter of the cylinders is smaller than the inner diameter of the arc grooves, so as to achieve a small deflection of the second support frame 232 and the ultrasonic probe 233.

[0083] like Fig.11 and Fig.12 As shown, in some embodiments, the probe component 230 further includes a clamping member 234, and the clamping member 234 is slidably connected to the second mounting bracket 231. The support component 210 has a clamping surface 212a disposed opposite to the detection surface 2331. When the clamping member 234 moves with the slide rail 220 to the side of the clamping surface 212a opposite to the ultrasonic probe 233, it can abut against the clamping surface 212a to limit the movement of the slide rail 220, and limit the probe component 230 to a position close to the disc assembly 100, so as to facilitate operations such as position adjustment or replacement of the probe component 230.

[0084] In this embodiment, the clamping surface 212a is the end surface of the slider 212 facing away from the ultrasonic probe 233. The clamping member 234 includes a clamping column 2341, a first limiting portion 2342, a second limiting portion 2343 and an elastic member 2344. The second mounting bracket 231 has a protruding portion, the protruding portion is provided with a sliding hole 2313, and the clamping column 2341 is slidably arranged in the sliding hole 2313. The first limiting portion 2342 is located at the top end of the clamping column 2341, and the second limiting portion 2343 is located at the bottom end of the clamping column 2341.

[0085] The clamping column 2341 and the first limiting portion 2342 are integrally formed bolts, and the second limiting portion 2343 is a nut threadedly connected to the bottom of the bolt. The elastic member 2344 is a coil spring sleeved on the clamping column 2341, and the coil spring is low connected between the protrusion and the second limiting portion 2343. Under the action of the elastic member 2344, the top of the first limiting portion 2342 is lower than the upper surface of the slide rail 220, so that the clamping member 234 can pass under the slider 212 as the slide rail 220 moves.

[0086] When the clamping member 234 moves to the side of the slider 212 facing away from the ultrasonic probe 233, the clamping member 234 can be pushed upward, so that the first limiting portion 2342 of the clamping member 234 abuts against the clamping surface 212a at the end of the slider 212. At the same time, the elastic member 240 provides a thrust to the clamping surface 212a, so that the clamping member 234 abuts against the clamping surface 212a, so as to limit the slide rail 220 from moving toward the inner side of the disc assembly 100. After the guide rail is slid outward again to separate the first limiting portion 2342 from the clamping surface 212a, the first limiting portion 2342 loses its force and then returns to the bottom of the slider 212 under the action of the elastic member 2344. At this time, the probe component 230 and the slide rail 220 can be returned to their original position under the elastic force of the elastic member 240.

[0087] like Figure 3 As shown, in some embodiments, the highly integrated pipeline ultrasonic detection plate may further include a coupling agent conveyor 300 for conveying a coupling agent to the ultrasonic probe 233. The coupling agent may be a coupling liquid such as water, grease, sodium silicate, etc., so that the ultrasonic probe 233 fills the coupling agent between the detection surface 2331 and the detected pipeline during the detection process, so that the ultrasonic wave can be effectively transmitted to the detected pipeline.

[0088] The coupler conveyor is disposed on the disc assembly 100. In this embodiment, the coupler conveyor can be disposed inside the mounting cavity 101 of the disc assembly 100. The coupling agent conveyor 300 has an input connector 310 and an output connector 320. A first clearance hole can be disposed on the first curved plate 110 of the disc assembly 100, and the input connector 310 can be connected to the coupling agent conveyor 300 in the mounting cavity through the first clearance hole. A second clearance hole can be disposed on the second curved plate 120 of the disc assembly 100, and the output connector 320 can be connected to the coupling agent conveyor 300 in the mounting cavity through the second clearance hole.

[0089] The input connector 310 is used to connect to a coupling agent delivery source, which may be a coupling agent storage container and a pressure pump. The input connector 310 and the coupling agent delivery source may be connected via a pipeline so that the coupling agent can be delivered into the coupling agent delivery device 300 via the input connector 310 .

[0090] The ultrasonic probe 233 has a coupling agent interface 2332, and the output connector 320 is used to connect the coupling agent interface 2332 through a pipeline. It can be understood that a plurality of output connectors 320 can be provided on each coupling agent conveyor 300, and each output connector 320 can be provided with a plurality of output ports. The coupling agent conveyor 300 has a channel inside, and the channel connects the input connector 310 and each output port of the output connector 320, so that each output port can output coupling agent. Each output port is connected to a coupling agent interface 2332 through a pipeline, so that the coupling agent conveyor 300 can be connected to multiple ultrasonic probes 233 at the same time. In this embodiment, two coupling agent conveyors 300 are installed on the disc assembly 100.

[0091] Under the action of the coupling agent conveyor 300, the coupling agent can be uniformly conveyed to each ultrasonic probe 233, and the arrangement of the coupling agent conveying pipeline of the ultrasonic probe 233 is simplified, making it easy to inspect and repair the pipeline.

[0092] like Figure 1 As shown, in some embodiments, the highly integrated pipeline ultrasonic detection panel further includes an image acquisition component 400 for acquiring a contact image between the ultrasonic probe 233 and the detected pipeline during the ultrasonic detection process, so as to facilitate operators to monitor the ultrasonic detection operation.

[0093] The image acquisition assembly 400 includes: a third mounting bracket 410, a camera 420, and a light source 430. The third mounting bracket 410 is disposed on the disc assembly 100. In this embodiment, the third mounting bracket 410 is connected to the first curved plate 110 of the disc assembly 100. The camera 420 and the light source 430 are both disposed on the third mounting bracket 410, and both the camera 420 and the light source 430 face the side of the probe component 230, that is, both the camera 420 and the light source 430 face the side of the measured pipeline.

[0094] Among them, the light source 430 can be an LED lamp. The light source 430 irradiates light in the direction of the measured pipeline and the probe component 230, thereby increasing the brightness of the ultrasonic detection area and the brightness of the image collected by the camera 420, which is convenient for monitoring by operators.

[0095] In a second aspect, an embodiment of the present application further provides an automated pipeline ultrasonic detection device, comprising: a frame, a driving device, and a highly integrated pipeline ultrasonic detection disc provided in the embodiment of the first aspect. The driving device is disposed on the frame, the highly integrated pipeline ultrasonic detection disc is disposed on the driving device, and the highly integrated pipeline ultrasonic detection disc can be driven by the driving device to move along the axial direction and / or circumferential direction of the detected pipeline.

[0096] Among them, the driving device can be a screw driving structure, a pneumatic driving structure or a hydraulic driving structure. The driving device enables the highly integrated pipeline ultrasonic detection disk to move along the axis or circumference of the pipeline to be tested, so that the pipeline to be tested can be fully automated with ultrasonic detection operations, thereby improving the efficiency of ultrasonic detection of the pipeline. During the ultrasonic detection process, the detection surface 2331 of the ultrasonic probe 233 can fit tightly with the pipeline to be tested under the action of the elastic component 240, so that the detection accuracy is high and the detection results are reliable, so that the weld defects of the austenitic stainless steel cast pipeline can be discovered in time to ensure the stable operation of the nuclear power plant equipment.

[0097] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
