Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline detection, in particular to a pipeline detection probe and device. BACKGROUND

[0002] Oil and gas field development, production and oil and gas transportation rely on pipelines to complete transportation. Due to the special nature of oil and natural gas, aging, corrosion, wear or accidental damage of the pipeline can cause leakage of oil and gas inside the pipeline, and thus cause serious accidents. Therefore, it is particularly important to regularly detect the pipeline.

[0003] Pipeline detection is usually detected by a magnetic flux leakage detector. The basic principle of pipeline magnetic flux leakage detection is that when the pipeline is fully magnetized by the magnetic steel carried by the detector, a relatively stable magnetic circuit is generated. When the detector passes through the recess, the magnetic force lines at the defect will be deformed, and a part of the magnetic force lines will leak out of the inner and outer surfaces of the pipeline to form a magnetic flux leakage field. The detection probe chip picks up the magnetic flux leakage field and converts it into an electrical signal. After specific software analysis, the position and size of the defect can be determined.

[0004] In related technologies, the polyurethane material used by the probe assembly requires a larger installation position, and the area of the gap between the two probes is too large, which directly affects the detection accuracy of the defect. At the same time, it is difficult to use on small-diameter equipment. Practical new type content

[0005] The present application aims to at least solve one of the technical problems existing in the related art.

[0006] To this end, the first aspect of the present application is to provide a pipeline detection probe, which comprises: a first elastic sheet having a first end and a second end; the first end is used to connect with the installation surface; a mounting base in a stepped shape, having a high step part and a low step part, the high step part is connected with the second end; a shell is arranged on the low step part; a detection assembly is arranged in the shell and is used to detect the inner wall of the pipeline.

[0007] In the above technical solution, by means of the fixed manner of the first elastic sheet and the probe main body support, the number of detection probes can be increased, and the installation position requirement of the detection probe is reduced, that is, the detection probe can be arranged more flexibly. In this way, in actual use, the detection range and structural strength of the detection device can be effectively increased, thereby reducing the missed detection range and improving the detection accuracy of the detection device. Further, by arranging the shell on the low step part, that is, the shell is sunken, the protrusion height of the detection probe can be reduced. In this way, in actual use, the impact or wear of the pipeline on the detection probe can be reduced, which helps to increase the detection accuracy and prolong the service life of the detection probe.

[0008] In some embodiments, a protective sheet is optionally provided on the side of the shell that is in contact with the inner wall of the pipeline.

[0009] In actual use, the detection probe needs to be in contact with the inner wall of the pipeline for a long time and continuously. By adding a protective member, the wear of the shell can be significantly reduced, thereby prolonging the overall service life of the detection probe and reducing the frequent replacement or maintenance requirements due to wear, thereby helping to maintain the accuracy and reliability of the detection results.

[0010] In some embodiments, the protective sheet is a ceramic sheet.

[0011] In some embodiments, a second elastic sheet is optionally provided, which is connected to the low-order part and has a mounting position for connecting to the surface to be mounted.

[0012] In the above technical solution, by introducing a second elastic sheet, an additional support can be provided to further enhance the stability of the detection probe on the surface to be mounted, so that the detection probe can better adapt to various complex environments during installation and use; especially in the case of pipeline vibration or external force impact, the design of the second elastic sheet can reduce the overall shaking and displacement of the detection probe, thereby ensuring the accuracy and reliability of the detection results.

[0013] In some embodiments, the second elastic sheet includes: a mounting section having a mounting position; a first bending section provided on one side of the mounting section and connected to the low-order part; and a second bending section provided on the other side of the mounting section.

[0014] In some embodiments, the low-order part has a hanging hole, and the second elastic sheet is hung in the hanging hole and freely connected to the low-order part.

[0015] In actual use, the tail of the low-order part has a hanging hole, and the second elastic sheet is hung in the hanging hole and freely connected to the low-order part. This connection method is not only simple and convenient, but also provides additional elastic deformation space for the second elastic sheet, which helps to further absorb and disperse external forces, so that the detection probe can better adapt to changes in the surface of the pipeline during installation and use. At the same time, it can also be left and right limited, thereby helping to maintain stable detection performance.

[0016] In some embodiments, the high-order part and the second end part are detachably connected. In this way, when the detection probe needs to be maintained, parts need to be replaced, or troubleshooting needs to be performed, the detachable connection allows the user to easily separate the mounting base and the second end part to adapt to different working requirements.

[0017] In some technical solutions, optionally, the second end and the higher-level part are provided with a first through hole arranged coaxially; a first bolt passes through the first through hole and is connected to a first nut.

[0018] In some technical solutions, the first elastic sheet optionally includes: a first sub-sheet, one end of which is designated as the first end; and a second sub-sheet, one end of which is detachably connected to the other end of the first sub-sheet, the other end of which is designated as the second end. This design improves the maintainability and durability of the detection probe. When one of the sub-sheets wears or is damaged, the user only needs to replace the damaged sub-sheet, without having to replace the entire first elastic sheet, thereby reducing maintenance and replacement costs.

[0019] In some technical solutions, optionally, the bending angle of the second sub-piece is greater than the complementary angle of the bending angle of the first sub-piece. This design results in the overall shape of the combined piece tilting towards the mounting surface. This tilt creates an acute angle between the upper surface of the housing (i.e., the mounting surface of the sensor or detection head) and the mounting surface, allowing the housing to fit more stably against the mounting surface after installation, reducing displacement or loosening caused by vibration or external forces.

[0020] According to a second aspect of this application, a pipeline inspection device is proposed, comprising the pipeline inspection probe proposed in any of the above-described technical solutions. Therefore, this pipeline inspection device possesses all the beneficial effects of any of the above-described technical solutions, which will not be elaborated further here.

DETAILED DESCRIPTION

[0028] In order to enable anyone skilled in the art to better understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0029] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0030] The following will be described in detail Figs. 1 to 3 by specific embodiments and application scenarios of the pipe detection probe and device provided by the embodiments of the present application.

[0031] With reference to Fig. 1 , Fig. 2 and Fig. 3 , some embodiments of the present application disclose a pipe detection probe, the structure of which comprises a first elastic sheet 100, a mounting base 200, a shell 300 and a detection assembly 400.

[0032] Specifically, the first elastic sheet 100 has a first end portion 110 and a second end portion 120. The first end portion 110 is used to be connected with a mounting surface. The mounting base 200 is generally in the shape of a “Z”-shaped ladder, comprising a high step portion 210 and a low step portion 220, and the high step portion 210 is connected with the second end portion 120. The shell 300 is arranged on the low step portion 220. The detection assembly 400 is arranged in the shell 300 and is used to detect the inner wall of the pipe.

[0033] In the above embodiment, by the fixed manner of the first elastic sheet 100 and the probe body support respectively, the arrangement number of the detection probe can be increased, the installation position requirement of the detection probe is reduced, that is, the detection probe can be arranged more flexibly. In this way, in actual use, the detection range and the structural strength of the detection device can be effectively increased, thereby reducing the missed detection range and improving the detection accuracy of the detection device. Further, by arranging the shell 300 on the low step part 220, that is, the shell 300 is sunken, the protruding height of the detection probe can be reduced, so that in actual use, the impact or wear of the pipeline on the detection probe can be reduced, which helps to increase the detection accuracy and prolong the service life of the detection probe.

[0034] In some embodiments, in order to further reduce the wear and improve the long-distance operation capability, the application also provides a protective piece 500 on the side (i.e. the upper side) of the shell 300 in contact with the inner wall of the pipeline.

[0035] In actual use, the detection probe needs to be in contact with the inner wall of the pipeline for a long time and continuously. By adding the protective piece 500, the wear of the shell 300 can be significantly reduced, thereby prolonging the overall service life of the detection probe and reducing the frequent replacement or maintenance requirements due to wear, thereby helping to maintain the accuracy and reliability of the detection results.

[0036] It can be understood that the protective piece 500 is usually made of wear-resistant and corrosion-resistant materials, such as ceramics, hard alloys or high-performance plastics, etc. These materials have very high hardness and wear resistance, which can effectively reduce the wear of the shell 300 when sliding or rubbing on the inner wall of the pipeline. In the present embodiment, the protective piece 500 is a ceramic sheet.

[0037] In some embodiments, the detection probe further comprises a second elastic sheet 600. The second elastic sheet 600 is connected with the low step part 220 and has a mounting position for connecting with the mounting surface.

[0038] By introducing the second elastic sheet 600, an additional support can be provided, which can further enhance the stability of the detection probe on the mounting surface, so that the detection probe can better adapt to various complex environments during installation and use; especially in the case of pipeline vibration or external force impact, the design of the second elastic sheet 600 can reduce the shaking and displacement of the detection probe as a whole, thereby ensuring the accuracy and reliability of the detection results.

[0039] In the above embodiment, the second elastic sheet 600 is generally in the shape of "V" and includes a mounting section 610, a first bent end 620 and a second bent end 630. Specifically, the mounting section 610 forms a mounting position for connecting with the mounting surface, the first bent section 620 is arranged on one side of the mounting section 610 and connected with the low step part 220, and the second bent section 630 is arranged on the other side of the mounting section 610.

[0040] In actual use, the tail of the low-order part 220 is provided with a hanging hole 230, and the first bending section 620 of the second elastic sheet 600 is formed with a hook away from one side of the mounting section 610 and extends into the hanging hole 230 to be freely hung with the low-order part 220. This connection method is not only simple and convenient, but also provides additional elastic deformation space for the second elastic sheet 600, which helps to further absorb and disperse external force, so that the detection probe can better adapt to the changes of the pipeline surface during installation and use, and at the same time, left and right limiting can be performed, thereby helping to maintain stable detection performance.

[0041] As a specific embodiment of the above embodiment, the first elastic sheet 100 and the second elastic sheet 600 are made of 65Mn metal elastic sheet.

[0042] In some embodiments, the high-order part 210 and the second end part 120 of the mounting base 200 are detachably connected. In this way, when the detection probe needs to be maintained, parts are replaced, or troubleshooting is performed, the detachable connection allows the user to easily separate the mounting base 200 and the second end part 120 to adapt to different work requirements.

[0043] In the above embodiment, the second end part 120 and the high-order part 210 are provided with a coaxially arranged first through hole 130; a first bolt 710 is arranged in the first through hole 130 and connected with a first nut 720. It can be understood that other detachable connection structures such as buckles and threads can also be used, and the present embodiment is not limited thereto.

[0044] In some embodiments, the first elastic sheet 100 includes a first sub-sheet 140 and a second sub-sheet 150. Specifically, one end of the first sub-sheet 140 is the first end 110; one end of the second sub-sheet 150 is detachably connected with the other end of the first sub-sheet 140, and the other end of the second sub-sheet 150 is the second end 120. This design improves the maintainability and durability of the detection probe. When one of the sub-sheets is worn or damaged, the user only needs to replace the damaged sub-sheet, without the need to replace the entire first elastic sheet 100, thereby reducing the maintenance and replacement cost.

[0045] In actual use, the bending angle of the second sub-sheet 150 is greater than the complementary angle of the bending angle of the first sub-sheet 140, and the overall shape after the combination of the two will present an inclination to the installation surface. This inclination forms an acute angle between the upper surface of the shell 300 (i.e. the installation surface of the sensor or detection head) and the installation surface, so that the shell 300 is more stably attached to the installation surface after installation, reducing displacement or loosening due to vibration or external force.

[0046] Exemplarily, the angle of the acute angle is 5°.

[0047] In the above embodiment, the first sub-piece 140 and the second sub-piece 150 are provided with coaxial second through holes, and the second bolt 730 is arranged in the second through holes and connected with the second nut 740. It can be understood that other detachable connection structures such as buckles and threads can also be used, and the present embodiment is not limited thereto.

[0048] In the above embodiment, the second nut 740 is a non-metal insert compression nut.

[0049] In some embodiments, one side of the shell 300 is provided with a glue pouring hole 310, and glue is poured in the shell 300, so as to ensure that the detection assembly 400 is firmly fixed inside the shell and prevent displacement or loosening of the detection assembly 400 due to vibration or external force during operation. This helps to improve the measurement accuracy and stability of the detection assembly 400 and ensure the accuracy and reliability of the detection results.

[0050] In the above embodiment, the detection assembly 400 includes a circuit board on which a Hall element and an eddy current coil assembly are mounted, and the Hall element can detect changes in the magnetic field. The function of the eddy current coil assembly is to determine whether the defect is an internal defect or an external defect according to the eddy current effect when the Hall element detects a pipeline defect.

[0051] In actual use, the shell 300 and the mounting base 200 are connected by bolts.

[0052] In some embodiments, the present application also provides a pipeline detection device, which has the pipeline detection probe provided in any of the above embodiments. Therefore, the detection device has all the beneficial effects of any of the above embodiments, which will not be described here.
