Description

Technical Field

[0001] This application relates to the technical field of pipeline detectors, and in particular to an integrally formed pipeline detection probe and detector. Background Art

[0002] In the pipeline transportation systems in fields such as oil and gas, and chemical industry, pipelines are prone to being affected by factors such as corrosion and extrusion during long-term operation, resulting in defects such as thinning of the pipe wall, cracks, and holes, which seriously threaten the safe operation of pipelines. Pipeline detection is a key link in ensuring pipeline safety, and the performance of its probe directly determines the detection effect. An effective pipeline detection probe needs to meet the requirements of being easily installed, being able to adapt to the limited space of small-diameter pipelines, and supporting the bidirectional operation of the detector, so as to ensure stable and reliable detection results in various pipeline environments.

[0003] Pipeline detection probes often adopt a multi-component assembly structure, mainly including mechanical components such as a probe housing, a connecting shaft, a spring, a support structure, screws, nuts, and spring pieces. These components are combined together by means of threaded connection, riveting, or welding to form the overall structure of the probe. This assembly form aims to achieve the support and positioning of the probe in the pipeline, as well as the contact with the pipe wall and the signal acquisition and transmission functions.

[0004] However, the multi-component assembled probe has significant defects: the connection points between components make the assembly process complex and time-consuming, and the connection parts are prone to loosening or damage in a complex pipeline environment, affecting signal stability; its structure has a large volume, making it difficult to adapt to the limited space layout of small-diameter detectors, and often interfering with the arrangement of the magnetic circuit and steel brushes, affecting the magnetization effect; at the same time, its mechanical structure design limits the adaptability of the probe during the bidirectional operation of the detector. These structural problems reduce the reliability, service life, and detection efficiency of the probe, and increase the maintenance burden. Summary of the Invention

[0030] Embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following examples do not represent all embodiments consistent with the present application. They are merely examples of systems and methods consistent with some aspects of the present application.

[0031] In many fields such as oil and gas, chemical industry, etc., pipeline transportation is widely used. Due to the long-term operation of pipelines, affected by factors such as medium corrosion and external force extrusion, defects such as thinning of the pipe wall, cracks, and holes are very likely to occur. These defects will seriously threaten the safe operation of the pipeline and even lead to major accidents such as leakage and explosion. Therefore, pipeline detection is crucial for ensuring pipeline safety, and the probe of the detector, as the core component, directly determines the detection effect.

[0032] In related embodiments, pipeline detection probes often adopt a multi-component assembly structure, mainly including mechanical components such as a probe housing, a connecting shaft, a spring, a support structure, screws, nuts, and spring pieces. These components are combined together by means of threaded connection, riveting, or welding to form the overall structure of the probe. This assembly form aims to achieve the support and positioning of the probe in the pipeline, as well as the functions of contact with the pipe wall and signal acquisition and transmission.

[0033] However, the connection points between the components of the multi-component assembled probe make the assembly process complex and time-consuming, and the connection parts are prone to loosening or damage in a complex pipeline environment, affecting signal stability; and its structure has a large volume, making it difficult to adapt to the limited space layout of small-diameter detectors, and often interfering with the magnetic circuit and steel brush arrangement, affecting the magnetization effect; at the same time, its mechanical structure design limits the adaptability of the probe when the detector runs bidirectionally. These structural problems reduce the reliability, service life, and detection efficiency of the probe, and increase the maintenance burden.

[0034] To solve the problems of low reliability and detection efficiency of the multi-component assembled pipeline detection probe, refer to Figures 1 - 4 , some embodiments of the present application provide an integrally formed pipeline detection probe, including: a wear-resistant contact layer 1, a probe body 2, and a support structure 3; The wear-resistant contact layer 1 is arranged on the top of the probe body 2 and is used to directly contact the inner wall of the pipeline 8 and provide wear-resistant protection; The probe body 2 is internally encapsulated with a circuit board assembly 4 that integrates detection and signal acquisition; The support structures 3 are symmetrically distributed on both sides of the probe body 2. The support structures 3 are made of flexible materials and form an integrally formed structure with the wear-resistant contact layer 1 and the probe body 2 through an integrally formed process.

[0035] It should be understood that the support structure 3 is made of a flexible material, enabling both sides of the probe body 2 to have the ability to deform to adapt to the scenarios of high-speed operation and two-way operation inside the pipeline 8. The flexible material can be selected from polyurethane rubber or silicone rubber. In addition, different materials are selected for different parts of the integrally formed pipeline detection probe. The probe body 2 is made of a wear-resistant material, specifically polyurethane rubber or ultra-high molecular weight polyethylene, which is used to enhance the durability of the probe body 2 when it is in contact with the inner wall of the pipeline 8 for a long time, effectively resist wear, and extend the service life of the probe. At the same time, the wear-resistant material also has excellent hardness and strength, ensuring the stable operation of the probe in the complex pipeline 8 environment and being not easily damaged. The support structure 3 is made of a flexible material, and these materials endow the support structure 3 with good elasticity and toughness. When running at high speed inside the pipeline 8 or facing changes in the direction of the pipeline 8, the flexible support structure 3 can absorb and buffer the external impact force, protecting the probe body 2 from damage. In addition, the deformation ability of the flexible material enables the probe to better adapt to pipelines 8 with different diameters and curvatures, improving the accuracy and flexibility of detection.

[0036] The integrally formed pipeline detection probe directly contacts the inner wall of the pipeline 8 through the wear-resistant contact layer 1 and provides wear-resistant protection. The circuit board assembly 4 for integrated detection and signal acquisition is encapsulated inside the probe body 2. The support structure 3 is made of a flexible material and is symmetrically distributed on both sides of the probe body 2. Through the one-piece forming process, it forms an integral structure with the wear-resistant contact layer 1 and the probe body 2, reducing the connection points of each component, improving the stability and reliability of the probe structure, thereby alleviating the impact of the multi-component assembled probe on reliability and detection efficiency, enhancing the structural stability and detection consistency, and solving the problem of low reliability and detection efficiency of the multi-component assembled pipeline detection probe.

[0037] In some embodiments, the manufacturing process of the integrally formed pipeline detection probe may be as follows: According to the performance requirements of each part of the product, different materials are selected, compounding agents are added according to the formula ratio, and mixing is carried out to form a colloid. During the process, the temperature, time, and feeding sequence need to be strictly controlled to ensure that various compounding agents are evenly dispersed in the colloid and the colloid quality is stable.

[0038] The circuit board assembly and the wear-resistant ceramic sheet are placed at the positioning part inside the mold, and a certain pressure is applied to the mold through equipment. The magnitude of the pressure is determined according to the material characteristics. Pressurization can make the colloid fully flow in the mold cavity, expel air, and make the colloid closely fit with other materials. While applying pressure, the mold is heated, and the temperature and time vary depending on the material type, formula, and thickness. Heating can promote the full cross-linking of different materials to achieve the required physical and mechanical properties of the whole.

[0039] When the mold cools to a certain temperature, the mold is opened, and the formed pipeline detection probe is taken out of the mold through the ejection mechanism or manually.

[0040] Remove the redundant rubber edges and flash on the edge of the pipeline inspection probe to make the size of the pipeline inspection probe meet the design requirements.

[0041] Specifically, the colloid can be polyurethane rubber. The elasticity and wear resistance of polyurethane rubber are balanced, and it can be directly integrally formed with the support structure 3, which is suitable for the adaptability detection of irregular pipelines (such as deformation and weld protrusion).

[0042] In some embodiments, the wear-resistant contact layer 1 is a ceramic sheet with a rectangular structure, and the edge of the wear-resistant contact layer 1 adopts a rounded corner structure.

[0043] It should be understood that the wear-resistant contact layer 1 is firmly bonded to the probe body 2 through integral molding, can withstand the operating pressure of the pipeline 8, and at the same time plays a wear-resistant role. The number of the ceramic sheets with a rectangular structure can be two to increase the contact area between the detection probe and the inner wall of the pipeline 8 to be detected, thereby improving the detection accuracy. The edge of the wear-resistant contact layer 1 adopts a rounded corner structure, which can not only improve the structural strength of the wear-resistant contact layer 1, but also reduce the stress concentration during installation or use, avoiding edge breakage. In addition, the rounded corner structure can also make the contact between the wear-resistant contact layer 1 and the inner wall of the pipeline 8 smoother, avoid scratching the inner wall of the pipeline 8, reduce the frictional resistance, thereby improving the sliding smoothness and service life of the detection probe and the pipeline 8. At the same time, the ceramic sheet with a rectangular structure is easy to process and install, which can ensure the stability and accuracy of the detection probe.

[0044] In some embodiments, the circuit board assembly 4 includes a circuit board, a magnetic flux leakage sensor, a signal acquisition and transmission circuit, and a power module; the magnetic flux leakage sensor, the signal acquisition and transmission circuit, and the power module are arranged on the circuit board. The magnetic flux leakage sensor is located on one side of the probe body 2 close to the wear-resistant contact layer 1 for detecting pipe wall defects; the signal acquisition and transmission circuit is used for processing detection signals; the power module is used for supplying power to the magnetic flux leakage sensor.

[0045] Specifically, the magnetic flux leakage sensor is located 1 mm below the wear-resistant contact layer 1 and forms a sealed housing through an integral molding process, which can withstand the pressure of the internal oil and gas operation of the pipeline 8 and has a good sealing effect.

[0046] The circuit board assembly 4 integrates a magnetic flux leakage sensor, a signal acquisition and transmission circuit, and a power module on the circuit board. The magnetic flux leakage sensor is arranged close to the wear-resistant contact layer 1 to detect pipe wall defects. The signal acquisition and transmission circuit processes detection signals, and the power module supplies power to the sensor, thereby optimizing the detection signal acquisition efficiency, reducing the system complexity, and improving the detection stability.

[0047] In some embodiments, the detection coil of the magnetic flux leakage sensor is disposed on one side of the probe body 2 close to the wear-resistant contact layer 1; the detection coils are arranged in an array circumferentially on the probe body 2 to form a 360° surrounding detection structure, so as to realize the full circumferential coverage detection of the inner wall of the pipeline 8.

[0048] It should be understood that by optimizing the layout and parameters of the detection coils, the detection performance can be further improved. For example, adjusting parameters such as the spacing, number of turns, and excitation current of the detection coils to meet the detection requirements of different pipe wall materials and thicknesses.

[0049] The detection coils of the magnetic flux leakage sensor are arranged in an array circumferentially on the probe body 2 and close to the wear-resistant contact layer 1, forming a 360° surrounding detection structure, which can improve the coverage of the inner wall defect detection of the pipeline 8, improve the integrity of the detection data, and enhance the ability to identify defects at different circumferential positions.

[0050] In some embodiments, the support structure 3 is a U-shaped structure, and a through cable channel is provided at a position on the inner side wall of the support structure 3 close to the bottom of the probe body 2, and the through cable channel extends along the length direction of the support structure 3 for fixing and protecting the cable passing through it.

[0051] It should be understood that the specific dimensions and shapes of the support structure 3 and its through cable channel can be adjusted and optimized according to actual needs to meet the application requirements of different pipeline 8 detection scenarios.

[0052] The design of the through cable channel not only facilitates the threading and fixing of the cable, but also effectively avoids the movement or damage of the cable during the detection process, thereby ensuring the stable transmission of signals. In addition, the channel can also provide a certain degree of protection to prevent adverse effects of external environmental factors on the cable, further improving the reliability and durability of the entire detection system.

[0053] The U-shaped design of the support structure 3 not only enhances its structural strength, but also provides an additional protection space for the cable. This design enables the cable to be effectively buffered when subjected to external forces, reducing the risk of damage. At the same time, the U-shaped structure is also convenient for installation and disassembly, facilitating users to maintain and replace the cable.

[0054] In some embodiments, at least two mounting holes 5 are provided at intervals along the length direction of the bottom of the support structure 3, and the mounting holes 5 penetrate the bottom of the support structure 3 for fixedly connecting with the pipeline detector through fasteners.

[0055] It should be understood that the fasteners can be selected as bolts, and by embedding the bolts into the mounting groove 7 of the pipeline detector, rapid and simple installation can be achieved.

[0056] At least two penetrating mounting holes 5 are arranged at intervals along the length direction at the bottom of the support structure 3, which can be fixedly connected to the detector through fasteners, thereby enhancing the stability of the overall structure of the probe, improving the installation firmness, and facilitating the adjustment and fixing of the installation position of the probe on the detector.

[0057] In some embodiments, the probe body 2 is made into a sealed housing by an integral molding process, and the sealed housing is integrally molded from a wear-resistant material to form a closed structure.

[0058] The probe body 2 is made of a wear-resistant material through an integrated molding process to form a sealed shell, forming a closed structure, which can enhance the overall mechanical strength, improve the waterproof and dustproof performance, reduce the impact of the external environment on the internal circuit components, and simplify the manufacturing process.

[0059] In some embodiments, a transition structure is provided on one side of the support structure 3 close to the probe body 2; the support structure 3 and the probe body 2 are combined through an embedded one-piece molding process, so that the wear-resistant material and the flexible material form an interlocking bonding interface at the transition structure.

[0060] It should be understood that the wear-resistant material and the flexible material form an interlocking interface through the transition structure, thereby reducing dependence on exposed welds or bolt structures, enhancing integrity, and improving structural strength and sealing performance.

[0061] The support structure 3 is combined with the probe body 2 through an embedded one-piece molding process, and a transition structure is provided on the side close to the probe body 2, so that the wear-resistant material and the flexible material form an interlocking structure at the bonding interface, which can enhance the connection strength between components, improve the structural integrity, and reduce the possibility of stress concentration at the bonding position of different materials.

[0062] Some embodiments of the present application further provide a pipeline detector, comprising the one-piece molded pipeline detection probe described in the above embodiments.

[0063] Since the pipeline detector has all the beneficial effects of the one-piece molded pipeline detection probe described in the above embodiment, they are not described in detail here.

[0064] In some embodiments, the one-piece molded pipeline detection probe also includes a mounting groove 7 and a detector steel brush 6; the mounting groove 7 is arranged in the middle of the detector steel brush 6; the one-piece molded pipeline detection probe is fixed in the mounting groove 7 through the mounting hole 5 at the bottom of the support structure 3.

[0065] It should be understood that a probe installation space is reserved in the middle of the detector steel brush 6, so that the installed pipeline detection probe does not occupy too much magnetic circuit area, ensuring the magnetization intensity, and can contact the pipeline 8 to meet the requirements of detecting wall defects. The pipeline detection probe enters the pipeline 8 with the pipeline detector. Through the elastic support structure 3, the wear-resistant contact layer 1 contacts the pipe wall to ensure the detection effect. In addition, through testing, in the curved pipeline section (curvature radius R = 1.5D), the pipeline detection probe still maintains the fit between the pipeline detection probe and the inner wall of the pipeline 8 through the deformation of the support structure 3 to ensure the continuity of the detection signal.

[0066] The integrated molded pipeline detection probe is fixed in the detector installation groove 7 through the installation hole 5 at the bottom of the support structure 3 and is installed in cooperation with the detector steel brush 6, which can improve the positioning stability of the probe during the detection of the pipeline 8, improve the accuracy of detection data acquisition, and at the same time enhance the connection reliability between the probe and the detector.

[0067] It should be understood that in a simulated pipeline containing prefabricated defects, cracks, corrosion pits, etc., by performing a two-way pulling test on the pipeline detector, the actual effect of the integrated molded pipeline detection probe is verified, and it is proved that it can accurately capture various defects in the pipeline 8, such as prefabricated cracks, corrosion pits, etc., and the detection signal is stable and continuous. In the pulling test, whether the pipeline detector is pushed forward or pulled back, the probe can maintain close contact with the inner wall of the pipeline and is not affected by the pipeline bending or defect morphology. This result not only verifies the detection accuracy and reliability of the integrated molded pipeline detection probe, but also further confirms the excellent performance of the integrated molded pipeline detection probe in practical applications.

[0068] As can be seen from the above technical solutions, the embodiment of the present application provides an integrated molded pipeline detection probe and a detector. The integrated molded pipeline detection probe includes: a wear-resistant contact layer 1, a probe body 2, and a support structure 3; the wear-resistant contact layer 1 is arranged on the top of the probe body 2 for directly contacting the inner wall of the pipeline 8 and providing wear-resistant protection; an integrated circuit board assembly 4 for detecting and signal collecting is encapsulated inside the probe body 2; the support structures 3 are symmetrically distributed on both sides of the probe body 2, and the support structure 3 is made of a flexible material and forms an integrated structure with the wear-resistant contact layer 1 and the probe body 2 through an integral molding process to solve the problems of low reliability and detection efficiency of the pipeline detection probe assembled with multiple components.
