Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0024] The following description, with reference to the accompanying drawings, describes a device, method, electronic device, and storage medium for measuring the wall thickness of a soft drink pipeline according to embodiments of this application. Addressing the technical problems mentioned in the background section, such as the inconvenience of portable and cumbersome testing equipment, and the high technical experience required of technicians, which hinders widespread application, this application provides a device for measuring the wall thickness of a soft drink pipeline. This device employs a dual-probe structure with one fixed and one movable probe, forming a conductive circuit on the outer wall of the pipeline. It generates a characteristic curve by combining current and displacement parameters and calculates the wall thickness, enabling continuous detection of the soft drink pipeline wall thickness. The device has a wide detection coverage, a simple structure, and is highly portable. It does not rely on the professional experience of operators, does not require damage to the pipeline itself, and is suitable for long-term online monitoring and periodic inspection of soft drink pipelines. It offers high safety and practicality.

[0025] Specifically, Figure 1 This is a schematic diagram of the structure of a steam pipe wall thickness measuring device provided in an embodiment of this application.

[0026] like Figure 1 As shown, the wall thickness measuring device 10 of the steam pipe includes: a positive probe 100, a negative probe 200, a scale 300, a data acquisition module 400, and a processing module 500.

[0027] Specifically, the positive probe 100 is used to fix it to the outer wall of the target soda pipe.

[0028] The negative probe 200 is used to move along the target direction on the outer wall of the target soda pipe.

[0029] One end of the positive probe 100 is connected to one end of the negative probe 200 via a wire to form a conductive circuit. The positive probe 100 and the negative probe 200 are parallel to the central axis of the target steam pipe and are on the same plane.

[0030] In actual implementation, the structures of both the positive probe 100 and the negative probe 200 can be as follows: Figure 2 As shown, one end is in contact with the target soda pipe, and the other end leads out a wire to connect the positive probe 100 and the negative probe 200, forming a conductive circuit with the target soda pipe.

[0031] The positive probe 100 serves as a fixed reference electrode. It provides the positive potential of the circuit, participating in the construction of a conductive loop, and also acts as a positional reference point, remaining in a constant position throughout the measurement to calibrate the detection start point and ensure all measurement data have a unified benchmark. The negative probe 200 serves as a movable measuring electrode. It provides the negative potential of the circuit, forming a conductive loop with the positive electrode, the pipe wall, and the wire. Furthermore, it moves according to the detection requirements, changing the distance between the two electrodes to collect current signals at different intervals, providing measured data for subsequent calculations of the pipe wall thickness.

[0032] It should be noted that in this embodiment, the positive probe 100 and the negative probe 200 are arranged parallel to and coplanar with the central axis of the pipeline. This ensures that the negative probe 200 moves linearly along the pipeline axis, maintaining a consistent detection direction, avoiding ranging deviations caused by oblique movement, and preventing fluctuations in contact resistance caused by changes in the contact angle and contact area between the electrode and the pipe wall, which could interfere with the actual current data.

[0033] The scale 300 is used to measure the straight-line distance between the positive probe 100 and the negative probe 200.

[0034] Furthermore, in this embodiment of the application, the straight-line distance between the positive probe 100 and the negative probe 200 can be measured using a scale 300 to facilitate subsequent thickness calculation.

[0035] Optionally, in one embodiment of this application, the scale 300 is disposed on the wire, and the wall thickness measuring device 10 of the soda pipe further includes a storage device.

[0036] A storage device for winding and storing a scale 300 and / or a wire, so that when the negative probe 200 moves along the target direction, the scale 300 and / or the wire are pulled out of the storage device, and the length of the scale 300 outside the storage device is taken as a straight-line distance.

[0037] Among them, such as Figure 2As can be seen, both the positive probe 100 and the negative probe 200 are structures combining probes with wires. The wires leading out from the two probes are connected to form a conductive circuit. To facilitate obtaining the straight-line distance between the positive probe 100 and the negative probe 200, the wire extending from the negative probe 200 can be used as a scale 300 to more intuitively obtain the straight-line distance. To avoid the scale 300 interfering with the measurement process, this embodiment of the application can use a storage device to store the scale 300.

[0038] In actual measurement, when the negative probe 200 moves, if the scale 300 is a wire extending from the negative probe 200, the scale 300 can be stored in the storage device in a coiled manner to avoid the extra scale 300 affecting the measurement. If the scale 300 is an additional structure set on the wire, it can be lifted together with the wire and stored in the storage device in a coiled manner, so that the spacing measurement and circuit conduction are completely synchronized, and the volume can be compressed for easy carrying.

[0039] The acquisition module 400 is used to acquire current data of the conductive circuit formed by the positive probe 100, the negative probe 200 and the outer wall of the pipe when the negative probe 200 moves along the target direction.

[0040] In this embodiment, the acquisition module 400 can be an ammeter, which can acquire the current data of the conductive circuit formed by the positive probe 100, the negative probe 200 and the outer wall of the pipe in real time when the negative probe 200 moves along the target direction.

[0041] The processing module 500 is used to generate a corresponding current-displacement change curve based on current data and straight-line distance, and to obtain the pipe thickness data of the target steam pipe along the target direction based on the current-displacement change curve.

[0042] The processing module 500 can acquire the current data collected by the acquisition module 400, combine it with the linear distance of the probe, fit and generate a current-displacement change curve, and then calculate and solve based on the curve to finally obtain the wall thickness value at different positions of the pipeline.

[0043] Optionally, in one embodiment of this application, the processing module 500 includes a construction unit and a computing unit.

[0044] The construction unit is used to construct an initial relationship function between the straight-line distance between the positive probe 100 and the negative probe 200, the theoretical current of the conductive circuit, and the design thickness of the target soda pipe based on the design parameters of the target soda pipe.

[0045] The calculation unit is used to calculate pipe thickness data based on the slope of the current-displacement change curve, the initial relationship function, current data, and straight-line distance.

[0046] In actual implementation, this embodiment of the application can designate point a at the positive probe 100 and point b at the negative probe 200, with the line connecting points a and b parallel to the central axis of the pipe and in the same plane. Let the displacement distance be L. ab As the pipe distance between the positive and negative probes increases, under a constant voltage, the displacement distance L... ab As the resistance increases, the current decreases.

[0047] When the pipe thickness is the design thickness (initial state), that is, the outer diameter D and inner diameter d are constant, the calculation relationship between current and resistance is as shown in formula (1). Then, the current I can be regarded as a line about the displacement distance L. ab The function.

[0048] (1) in, I The current flowing through section ab in the tube. V ab The potential difference between a and b, D is the outer diameter of the pipe, d is the inner diameter of the pipe, ρ is the resistivity of the pipe material, and L is the inner diameter of the pipe. ab Let be the length of the pipe between a and b.

[0049] However, in the actual testing process, when L ab At a certain time ， That is, when the pipe thickness changes, the inner diameter d at any point b is an unknown constant. And V ab D and ρ remain constants. At this point, only the change in the inner diameter affects the slope of the current-displacement curve, i.e., the influence function of the inner diameter d. I (L) ab ） The first derivative of the function. I ( L ab The calculation process of the first derivative of is shown below.

[0050] like Figure 3 As can be seen, the dashed line represents the Ix graph of the pipe without oxide scale, and the solid line represents the Ix graph of the pipe with oxide scale. The slope of the curve is: k= = (2) The calculation here uses the infinitesimal method. Let b and b' be two very close points on the pipe, and let the distance between them be Δb, which approaches 0 infinitely. Therefore, the slope calculated by equation (2) can be considered as the slope at point b.

[0051] Substituting equation (1) into equation (2), we can obtain the following result after calculation: k= (3) Based on the aforementioned current-displacement curve, at any given location k , L ab To ensure that the values ​​are definite and can be read by a computer, the outer diameter D and voltage V are... ab Since the resistivity ρ is also a constant, the value of d can be calculated according to formula (4).

[0052] d= (4) In summary, the embodiments of this application can accurately measure the pipe thickness at any point by using the derivative k of the current and displacement at any point, which can quickly and accurately obtain the pipe wall thickness value, and has the dual characteristics of ease of operation and high measurement accuracy.

[0053] Optionally, in one embodiment of this application, the wall thickness measuring device 10 for the steam pipe further includes a power source.

[0054] The power supply is used to output a voltage that meets preset conditions in order to form a conductive circuit between the positive probe 100, the negative probe 200 and the outer wall of the pipe.

[0055] In some embodiments, a constant, minute voltage can be used to form a closed loop between the positive and negative poles, wires, and pipes, which has safety advantages and can effectively reduce the risk of electric shock.

[0056] Optionally, in one embodiment of this application, the wall thickness measuring device 10 for the steam pipe further includes an early warning module.

[0057] The early warning module is used to generate a pipe thickness variation curve of the target steam pipe along the target direction based on the pipe thickness data, and generate a corresponding early warning signal when the pipe thickness variation curve meets the preset early warning conditions.

[0058] In actual implementation, the embodiments of this application can set the initial pipe inner diameter as d0, and then change the pipe inner diameter d according to L. ab The changing relationship is reflected in a curve on the early warning module, which can be a display screen to more intuitively show the thickness changes. When the thickness d-value exceeds a certain warning value (configurable), an early warning signal is generated. This eliminates the need for expensive specialized equipment; simply observing the peak data on the display screen is sufficient. Once the indicated value exceeds the preset warning threshold, the thinning location of the pipe can be quickly pinpointed, providing precise guidance for subsequent localized repairs and significantly improving fault handling efficiency. Combined with… Figure 4 As shown, the working principle of the wall thickness measuring device 10 for the steam and water pipeline of this application is explained in detail with reference to one embodiment.

[0059] like Figure 4As shown, the wall thickness measuring device 10 for a steam pipe may include: a positive probe 100, a negative probe 200, a scale 300, a data acquisition module 400, a processing module 500, a storage module 600, a power supply 700, and an early warning module 800.

[0060] The structures of the positive probe 100 and the negative probe 200 can be as follows: Figure 2 As shown, a wire is led out from each end of the positive probe 100 and the negative probe 200, and a small copper block (5mm) is connected to the end of the wire. (5mm) as the probe.

[0061] The scale 300 and the wires can be stored in the storage module 600, which can be installed in the middle of the two wires. The wire length can be adjusted according to actual needs, ranging from 10 to 500 mm. When not in use, the excess wire of the negative probe 200 can be retracted into the storage module 600 in a manner similar to a measuring tape.

[0062] Furthermore, in this embodiment, a rigid support material (the length of which can be determined) can be wrapped between the positive probe 100 and the storage module 600, and between the negative probe 200 and the storage module 600. The excess part of the wire of the negative probe 200 is wrapped with a soft material and marked with a scale to form a scale 300.

[0063] In addition, the scale 300 can also be additionally set on the wire and similarly stored in the storage module 600.

[0064] In order to achieve automated data processing, the storage module 600 of this application embodiment can also collect the length of the internally stored ruler 300 that is pulled out during each measurement and upload it to the processing module 500 to achieve automatic collection of straight-line distance.

[0065] The acquisition module 400 can be connected to the processing module 500 via a lead-out connection cable. The processing module 500 has the functions of reading current, displacement length, and calculating the rate of change of current with displacement. Finally, the pipe thickness is calculated through the built-in calculation module.

[0066] The early warning module 800 can display an image of the pipe thickness (y-axis) and displacement length (x-axis), and will issue an alarm when the thickness is less than or equal to the thickness warning value.

[0067] In practical use, the embodiments of this application may include the following steps: Step S1: Use sandpaper or other tools to sand the outer wall of the pipe along the measurement path to remove the oxide layer. Ensure that a sufficient conductive area is created on the surface for the probe to test.

[0068] Step S2: Connect the positive probe 100 to any point on the pipeline and fix it in place. At this time, the wires of the excess negative probe 200 are all retracted in the storage module 600. The negative probe 200 and the rigid section below it are adjacent to the positive probe. The line connecting the positive probe 100 and the negative probe 200 is parallel to the central axis of the pipeline and is on the same plane.

[0069] Step S3: By outputting a constant small voltage through the power supply 700, a closed circuit can be formed between the positive probe 100, the negative probe 200, the wire, and the pipe.

[0070] Step S4: Pull the scale 300 parallel to obtain a current-displacement change curve while measuring the movement distance. The processing module 400 can perform a series of calculations using this curve to obtain the pipe thickness at each point.

[0071] Step S5: Read the real-time pipe thickness d on the early warning module 800. When the pipe thickness d exceeds the warning value, the pipe section will be processed.

[0072] Step S6: Following the target direction, simultaneously move the positive and negative probes circumferentially and repeat the measurement n times (n is greater than or equal to 20), and read its d value.

[0073] The wall thickness measuring device for steam and water pipelines proposed in this application can adopt a dual-probe structure with one fixed and one movable probe. A conductive circuit is formed based on the outer wall of the pipeline. A characteristic curve is generated by combining current and displacement parameters to calculate the wall thickness, enabling continuous detection of the steam and water pipeline wall thickness. The device has a wide detection coverage, a simple structure, and is highly portable. It does not rely on the professional experience and skills of operators, does not require damage to the pipeline itself, and is suitable for long-term online monitoring and periodic inspection of steam and water pipelines. It offers high safety and practicality. Therefore, it solves the technical problems in related technologies where the detection equipment is inconvenient to carry, cumbersome to operate, and requires a high level of technical experience from technicians, making it difficult to promote and apply.

[0074] Next, referring to the accompanying drawings, a method for measuring the wall thickness of a steam-water pipeline according to an embodiment of this application is described.

[0075] Figure 5 This is a flowchart of a method for measuring the wall thickness of a steam pipe according to an embodiment of this application.

[0076] like Figure 5 As shown, the method for measuring the wall thickness of the steam pipe includes the following steps: In step S501, in response to the target soda pipe's outer wall meeting preset measurement conditions, the positive probe is fixed at any position on the target soda pipe.

[0077] In step S502, the negative probe is controlled to move along the target direction on the outer wall of the target soda pipe, and the current data of the conductive circuit formed by the positive probe, the negative probe and the outer wall of the pipe is acquired.

[0078] In step S503, based on the current data and straight-line distance, a corresponding current-displacement change curve is generated, and based on the current-displacement change curve, the pipe thickness data of the target steam pipe along the target direction is obtained.

[0079] It should be noted that the foregoing explanation of the embodiment of the steam and water pipe wall thickness measuring device also applies to the steam and water pipe wall thickness measuring method of this embodiment, and will not be repeated here.

[0080] The method for measuring the wall thickness of a soft drink pipeline proposed in this application employs a dual-probe structure with one fixed and one movable probe. A conductive circuit is formed on the outer wall of the pipeline, and a characteristic curve is generated by combining current and displacement parameters to calculate the wall thickness. This enables continuous detection of the soft drink pipeline wall thickness, providing a wide detection coverage. The device is simple in structure, highly portable, does not rely on the professional experience and skills of operators, and does not require damage to the pipeline itself. It is suitable for long-term online monitoring and periodic inspection of soft drink pipelines, offering high safety and practicality. This solves the technical problems in related technologies where the detection equipment is inconvenient to carry, cumbersome to operate, and requires a high level of technical experience from technicians, hindering its widespread application.
