[0025] The present application will be described below in conjunction with the preferred implementation steps, Figure 1 is a schematic diagram of the expansion information detection system of the buffer layer sample provided according to the embodiments of the present application, as Figure 1 shown, the system comprises:

[0026] The sample containing module 102 comprises a buffer layer container and a punching die, and the punching die is used to fix the buffer layer sample in the buffer layer container.

[0027] The water injection control module 104 comprises a water tank and a solenoid valve, and the solenoid valve is used to control the on-off state of the water tank to the buffer layer container;

[0028] The displacement detection module 106 comprises a displacement sensor, and the displacement sensor is vertically aligned with the buffer layer sample. The displacement sensor is used to collect the expansion height data of the buffer layer sample under the condition that the water tank injects water into the buffer layer container.

[0029] The display recording module 108 is used to receive and display the expansion height data collected by the displacement sensor.

[0030] Optionally, in the present embodiment, the buffer layer sample is a small piece of material cut from the buffer layer material of a cable or similar electrical equipment, which is used to test its expansion performance under water absorption conditions in the laboratory.

[0031] Optionally, in this embodiment, the sample holding module is composed of a buffer layer container and a punching die, which is used to fix and hold the buffer layer sample, ensuring the stability of the sample position during water injection and swelling process. The punching die standardizes the water contact area of the sample, thereby eliminating the measurement errors caused by the difference in contact area between different samples.

[0032] Optionally, in this embodiment, the water injection control module contains a water tank and a solenoid valve, which is used to accurately control the process of injecting water into the buffer layer container. The solenoid valve can automatically control the flow of water, open and close at the preset time, ensure the consistency of each water injection condition, and improve the repeatability and accuracy of the test.

[0033] Optionally, in this embodiment, the displacement detection module is composed of a displacement sensor, which is vertically aligned with the buffer layer sample, used to measure the swelling height of the sample under water injection conditions in real time and non-contact manner. Its high precision and real-time nature overcomes the limitations of contact measurement tools, improving the accuracy of measurement and the reliability of data.

[0034] Optionally, in this embodiment, the display and recording module is used to receive data from the displacement detection module and display the swelling height of the buffer layer sample in real time, while automatically recording data for subsequent analysis and generating swelling height-time curve, improving the efficiency and objectivity of data processing.

[0035] Optionally, in this embodiment, first, select the appropriate buffer layer sample, cut it into 100mm x 100mm size, then place the sample in the punching die, and through the fixed action of the die, ensure that the sample is flat and wrinkle-free in the container, and the water contact area is consistent.

[0036] Manually add water to the 10L water tank in the water injection control module, ensure the water level reaches the preset test height. Then, adjust the laser displacement sensor in the displacement detection module, so that its laser beam is vertically aligned with the center of the sample, and calibrate the zero point to ensure the accuracy of the measurement.

[0037] On the touch screen of the display and recording module, set the water injection time (e.g. 30s), the total detection time (e.g. 300s) and the data recording interval (e.g. 1s / time). These parameters should be adjusted according to the characteristics of the sample and the experimental requirements to ensure the integrity of the data and the efficiency of the experiment.

[0038] Start the test, the solenoid valve of the water injection control module automatically opens, injects water into the sample, and automatically closes when the water injection time reaches the set value (e.g. 30s). At this time, the displacement sensor of the displacement detection module starts to collect and record the swelling height data of the sample in real time, and the data is transmitted to the display and recording module in real time, displaying the curve of the swelling process.

[0039] After the test, the display and recording module automatically generates the maximum expansion height of the sample and the complete expansion height-time curve, and the setting of the data recording interval enables the curve to reflect every tiny change in the expansion process of the sample in detail. By analyzing the curve, the expansion rate can be accurately quantified, and the performance of the buffer layer material can be evaluated.

[0040] Further, a structural diagram of an expansion height detection device for a buffer layer sample is shown in FIG. 2. As shown in FIG. 2, the buffer layer sample is cut into 100 mm x 100 mm, fixed in the buffer layer container 206 through the punching die 208, and ensured to be flat and wrinkle-free. The water tank 202 is manually filled with water to the liquid level line, the laser displacement sensor 210 is calibrated to make the laser beam vertically aligned with the center of the sample, and the zero point is set. The water injection time (e.g., 30 s), the total detection time (e.g., 300 s), and the data recording interval (1 s / time) are set through the 10-inch touch screen. After starting the test, the electromagnetic valve 204 is automatically opened to inject water to the sample, and is automatically closed after 30 s. The laser displacement sensor 5 synchronously collects the expansion height data, and the touch screen displays the curve in real time. After the test, the maximum expansion height (e.g., 25 mm) and the expansion rate curve are automatically generated, the accumulated water in the container is discharged through the drain valve, and the sample is replaced for repeated test. Figure 2 It should be noted that the embodiment is based on automatic water injection and non-contact displacement measurement. When the electromagnetic valve is opened, water flows from the water tank to the buffer layer container to inject water to the sample. During the water injection process, the laser displacement sensor continuously monitors the expansion height of the sample, and the data is displayed and recorded in real time through the display and recording module. By accurately controlling the water injection time and the data recording frequency, the system can generate a detailed expansion process curve, thereby realizing accurate detection and analysis of the expansion information of the buffer layer sample.

[0041]

[0042] ​By the examples provided by the present application, the electromagnetic valve in the water injection control module can automatically control the on-off state and water injection time of the water tank to the buffer layer container, thereby ensuring the consistency of water injection conditions for each test and significantly improving the controllability and repeatability of test conditions. The displacement sensor (such as a laser or infrared sensor) used in the displacement detection module is vertically aligned with the buffer layer sample, which can collect real-time and accurate expansion height data without physical contact with the sample under the condition of water injection in the buffer layer container, thereby avoiding sample deformation and reading errors caused by contact measurement. The display recording module receives and displays the expansion height data collected by the displacement sensor, which can automatically record the data, facilitate real-time monitoring and subsequent analysis of the dynamic change law of the expansion rate, and improve the scientificity and analysis accuracy of the test results. Through the cooperative work of the sample containing module, the water injection control module, the displacement detection module, and the display recording module, the automation, standardization, and high precision of the buffer layer sample expansion information detection are realized, which greatly improves the detection efficiency and the reliability of the results, thereby realizing the technical effect of improving the accuracy of the buffer layer sample expansion information detection.

[0043] As an optional solution, the display recording module is further configured to generate and display an expansion rate curve of the buffer layer sample based on the expansion height data, the expansion rate curve being used to indicate the mapping relationship between the expansion height data and the water injection time.

[0044] Optionally, in the present embodiment, the expansion rate curve is a curve generated by the display recording module through algorithm processing based on the expansion height data collected by the displacement detection module, which reflects the law of the expansion rate of the buffer layer sample changing with time during the water injection process. The calculation of the expansion rate can be, but is not limited to, completed by comparing the ratio of the expansion height difference value and the time difference value of two consecutive time points.

[0045] Optionally, in the present embodiment, the display recording module internally contains a data processing unit, which can receive the expansion height data from the displacement detection module and calculate the expansion height difference value of two adjacent time points according to the set data recording interval (such as 1s / time). By comparing these difference values with the corresponding time intervals, the module can calculate the instantaneous expansion rate of each time point.

[0046] Based on the calculated instantaneous expansion rate, the display recording module can generate a complete expansion rate curve. The horizontal coordinate of the curve is the water injection time, and the vertical coordinate is the expansion rate, which clearly shows the change trend of the expansion rate of the sample with time during the water injection process.

[0047] Through the 10-inch touch screen, the display and recording module can display the generated expansion rate curve in real time, so as to facilitate the experimenters to observe and analyze the expansion of the sample in time. The curve not only provides intuitive expansion rate information, but also indicates the rapid change in the initial expansion and the time node when the expansion reaches a stable state, thereby providing data support for evaluating the expansion performance of the buffer layer material.

[0048] In addition to real-time display, the display and recording module also stores the expansion height data and the expansion rate curve, so as to facilitate the arrangement, analysis and comparison of experimental data and provide detailed experimental basis for subsequent material research and product improvement.

[0049] Through the embodiments provided in the present application, the display and recording module can not only provide real-time expansion height display, but also generate an expansion rate curve, thereby providing comprehensive and accurate expansion information.

[0050] As an optional solution, the display and recording module comprises a touch screen, and the touch screen is used to display the expansion height data and the expansion rate curve.

[0051] Optionally, in the present embodiment, the touch screen is an interactive screen integrated in the display and recording module, and the user can directly operate and view information on the screen. As an interface for human-computer interaction, the touch screen can clearly and timely display the data output of the detection system.

[0052] Optionally, in the present embodiment, the touch screen in the display and recording module is a 10-inch high-definition display screen with touch function, so as to facilitate the experimenters to directly operate and set on the screen. The resolution of the screen is sufficient to clearly display complex curves and a large amount of digital information.

[0053] During the experiment, the touch screen can display the expansion height data collected by the displacement detection module in real time, and the data is updated in the form of numbers in time, thereby helping the experimenters to monitor the expansion process of the sample.

[0054] Based on the expansion height data, the display and recording module can automatically calculate the instantaneous expansion rate of the sample and generate an expansion rate curve on the touch screen. The curve describes the trend of the expansion rate of the sample under the water injection condition with respect to time, thereby providing an intuitive graphical display for evaluating the material performance.

[0055] Optionally, in the present embodiment, the experimenters can set the experimental parameters such as water injection time and total detection time through the touch screen, and can also export the data through the screen after the experiment is completed and save the data as an electronic document, thereby facilitating subsequent analysis and report writing.

[0056] Optionally, in this embodiment, the data display on the touch screen takes the form of intuitive graphs, in addition to the swelling height values, through the swelling rate curve, the experimenter can quickly identify the peak time of material swelling, the time required for the swelling rate to reach stability, and other key information.

[0057] Optionally, in this embodiment, the display and recording module also allows the experimenter to generate an experimental report through the touch screen, which contains detailed swelling data, graphs, and experimental condition information.

[0058] Through the embodiments provided in this application, the touch screen in the display and recording module not only realizes effective data display, but also provides a more in-depth material performance analysis means through the generation of the swelling rate curve, greatly enhancing the intuitiveness and interactivity of the detection system.

[0059] As an optional solution, the display and recording module includes a touch screen, which is used to display a parameter input interface before the water tank injects water into the buffer layer container, and the parameter input interface is used to indicate the input and display of the water injection parameters corresponding to the water injection process.

[0060] Optionally, in this embodiment, the parameter input interface is an operation interface that appears on the touch screen of the display and recording module before the water injection process starts, which is used to guide the experimenter to input and display the water injection parameters, including but not limited to water injection time, total detection time, data recording interval, etc., to ensure the accurate control of the water injection process and the consistency of the detection conditions.

[0061] Optionally, in this embodiment, the parameter input interface provides a friendly operation platform for the experimenter, allowing them to input and adjust water injection parameters such as water injection time, total detection time, and data recording interval, which are crucial for subsequent swelling detection and directly affect the accuracy and comparability of the data.

[0062] The touch screen can display the input parameters in real time, and the experimenter can check if the settings are correct, and if necessary, can modify them before the water injection starts, ensuring that all parameters are accurate and error-free according to the requirements of the experimental design.

[0063] Once the experimenter confirms the water injection parameters, the display and recording module transmits these data to the water injection control module, and the electromagnetic valve automatically opens and closes according to the received water injection time instructions, achieving accurate control of the water injection process and improving the standardization level of the test.

[0064] After the parameter setting is completed, the display and recording module will be initialized according to the set data recording interval, preparing to receive the swelling height data from the displacement detection module, and preparing for subsequent real-time display and recording.

[0065] Through the examples provided by the present application, not only can real-time display of data and curves be provided, but more importantly, through the parameter input interface of the touch screen before water injection, precise control of the water injection conditions is achieved, ensuring that each test is conducted under the same conditions, greatly enhancing the reliability and repeatability of the experimental results.

[0066] As an optional solution, the water injection parameters include a water injection duration parameter, a detection duration parameter, and a data recording interval parameter. The water injection duration parameter is used to indicate the duration of water injection from the water tank to the buffer layer container. The detection duration parameter is used to indicate the duration of displacement sensor acquisition of the swelling height data. The data recording interval parameter is used to indicate the time interval of displacement sensor acquisition of the swelling height data.

[0067] Optionally, in the present embodiment, the water injection parameters in the detection system of the present embodiment refer to various set values related to water injection process control and data acquisition, mainly including a water injection duration parameter, a detection duration parameter, and a data recording interval parameter, for precisely adjusting the water injection conditions and ensuring the accuracy of the detection and the effectiveness of the data.

[0068] Optionally, in the present embodiment, the water injection duration parameter determines the duration of water injection from the water tank to the buffer layer container, and is the basic setting for the automatic water injection of the water injection control module, directly affecting the water absorption degree of the sample and the initial stage of the swelling state. The detection duration parameter specifies the total time range of displacement detection module acquisition of the swelling height data, ensuring the complete monitoring of the entire swelling process, whether during water injection or the continuous swelling stage after water injection. The data recording interval parameter defines the time interval of displacement sensor acquisition of the swelling height data, determines the density of data sampling, and affects the details and resolution of the swelling rate curve, which is a key setting for improving detection accuracy.

[0069] Optionally, in the present embodiment, through the touch screen of the display recording module, the experimental personnel can input the water injection duration parameter, which tells the electromagnetic valve in the water injection control module when to start water injection and when to stop water injection. Correct water injection duration is crucial for simulating the water absorption and swelling process of the buffer layer in the real environment.

[0070] The experimental personnel also need to set the detection duration parameter, which determines the time range of displacement detection module data acquisition during the entire test period, including the state before water injection, the water injection process, and the swelling change after water injection. A longer detection duration helps to fully understand the water absorption and swelling characteristics of the material, especially in the rapid change stage of the initial swelling period.

[0071] The data recording interval parameter allows the experimental personnel to specify the frequency of displacement sensor data acquisition. Short time intervals can capture subtle changes in the material swelling process, ensuring high resolution of the swelling rate curve, which is particularly important for analyzing the dynamic response of the material.

[0072] Through the embodiments provided in the present application, the display recording module of the present application can be used to accurately set the water injection parameters, realize high controllability of the experimental conditions, and further obtain high-quality swelling height data and swelling rate curves, thereby providing a solid data foundation for evaluating the performance of the buffer layer material.

[0073] As an optional solution, the diameter of the buffer layer sample is 100 mm, the diameter of the punching mold is 80 mm, and the buffer layer sample is fixed in the buffer layer container through the punching mold. The range of the displacement sensor is 0-400 mm, and the displacement sensor is a laser displacement sensor or an infrared displacement sensor.

[0074] Optionally, in the present embodiment, the buffer layer sample refers to a cable buffer layer material sample for detection, which is cut into a circular shape with a fixed diameter of 100 mm, ensuring the consistency of the sample size and being conducive to the standardized swelling performance detection. The punching mold is a disc-shaped mold with a specific diameter, which is set to 80 mm, smaller than the diameter of the buffer layer sample, for fixing the sample during the detection process while ensuring the standardization of the sample contact area with water, reducing the influence of edge effects, and improving the accuracy of the detection. The displacement sensor is used to measure the swelling height of the buffer layer sample under the water injection condition, and the range of the displacement sensor mentioned in the present application covers 0-400 mm, ensuring the accurate measurement ability of a large range of swelling height. The two possible choices, laser displacement sensor and infrared displacement sensor, are both non-contact measurement methods, avoiding potential interference to the sample form by direct contact.

[0075] Optionally, in the present embodiment, to ensure the standardization and accuracy of the detection, the sample containing module adopts a standard buffer layer sample with a diameter of 100 mm, which is fixed in the buffer layer container through a punching mold with a diameter of 80 mm, forming a strict sample processing procedure. In addition, the displacement sensor in the displacement detection module has a wide range, which can adapt to the large-scale swelling change of the sample under the water injection condition, and selects two advanced non-contact measurement technologies, laser displacement sensor and infrared displacement sensor, to reduce the physical impact on the sample during the measurement process and improve the authenticity and reliability of the detection results.

[0076] Optionally, in the embodiment, a circular buffer layer sample with a diameter of 100 mm is selected to ensure that the size of the sample meets the detection standard and improve the comparability of the detection. The punching die is placed in the buffer layer container, and the diameter of the die is 80 mm, which is smaller than the diameter of the sample. In this way, it can be ensured that the sample is properly fixed and the area in contact with water is standardized, reducing edge effects and improving the consistency and accuracy of the detection. The buffer layer sample is fixed in the buffer layer container through the punching die, and the sample should be flat and wrinkle-free to ensure the uniformity of the swelling process after water injection. A displacement sensor with a range of 0-400 mm is selected to ensure that it can cover the maximum swelling height that may occur during the detection process. Whether it is a laser displacement sensor or an infrared displacement sensor, it should be vertically aligned with the center of the sample to achieve non-contact high-precision swelling height measurement. Water is injected into the container, and the displacement sensor monitors the swelling height of the sample in real time. Since a non-contact measurement method is used, sample deformation and data distortion caused by contact measurement can be avoided. The display and recording module receives the data collected by the displacement sensor, displays the swelling height in real time, and generates and displays the swelling rate curve after the detection is completed, which facilitates in-depth analysis of the swelling characteristics of the buffer layer material.

[0077] Through the embodiments provided in the present application, the swelling performance of the buffer layer sample under standard conditions is ensured to be accurately detected, and the mold size and sensor type and range used provide technical support for achieving this goal.

[0078] Figure 3 is a flowchart of a buffer layer sample swelling information detection method provided by the embodiment, which includes:

[0079] S302, the buffer layer sample is fixed in the buffer layer container through the punching die;

[0080] S304, calibrate the displacement sensor, and the calibrated displacement sensor is vertically aligned with the buffer layer sample;

[0081] S306, control the water tank to inject water into the buffer layer container through the electromagnetic valve;

[0082] S308, in the process of injecting water into the buffer layer container by the water tank, the swelling height data of the buffer layer sample is collected by using the displacement sensor, and the swelling height data is displayed.

[0083] Optionally, in the embodiment, the buffer layer sample is a buffer layer material sample cut from a cable or similar electrical equipment, which is used for the swelling performance detection of the present application. The sample needs to be cut to a specific size, and in the embodiment, the diameter is 100 mm.

[0084] Optionally, in this embodiment, the punching mold is a tool used to fix the buffer layer sample and ensure its contact area with water is standardized. The diameter of the punching mold is 80 mm, which is smaller than the diameter of the sample, so that the sample can maintain a stable state during the detection process.

[0085] Optionally, in this embodiment, the buffer layer container is a device used to contain the buffer layer sample and conduct water injection. It is the main component of the sample containing module.

[0086] Optionally, in this embodiment, the displacement sensor is the core component of the displacement detection module, which is used to measure the swelling height of the buffer layer sample in real time. The range is 0-400 mm, and laser displacement sensor or infrared displacement sensor can be selected.

[0087] Optionally, in this embodiment, the electromagnetic valve is the control element of the water injection control module, which is used to accurately control the water injection process from the water tank to the buffer layer container, ensuring the consistency and controllability of the water injection conditions.

[0088] Optionally, in this embodiment, the water tank is part of the water injection control module, which is used to store the detection water. The capacity is 10 L, which can meet the needs of water injection test.

[0089] Optionally, in this embodiment, the display and recording module includes a touch screen display device, which is used to receive and display the swelling height data collected by the displacement sensor, and can also record the data and generate the swelling rate curve.

[0090] Optionally, in this embodiment, first, the buffer layer sample is placed in the punching mold, and the mold is placed in the buffer layer container to realize the standardized fixation of the sample. This step ensures the stability of the sample position during water injection, the consistency of the water contact area, and avoids measurement errors caused by sample movement or deformation.

[0091] The displacement sensor is calibrated to ensure the accuracy and reliability of the measurement. The calibrated sensor should be vertically aligned with the center of the buffer layer sample to ensure accurate measurement of the vertical displacement of the sample during swelling.

[0092] The electromagnetic valve is used to control the water injection from the water tank to the buffer layer container. The opening and closing of the electromagnetic valve strictly follow the preset time parameters to realize precise control of the water injection process and ensure the standardization of the test conditions.

[0093] During the water injection process, the displacement sensor continuously collects the swelling height data of the sample, which is transmitted to the display and recording module in real time. The current swelling height is displayed on the touch screen. This implementation step realizes real-time monitoring and visualization of data, which is convenient for the experimenter to understand the swelling state of the sample.

[0094] It should be noted that the present embodiment fixes the sample by punching die, precisely controls water injection by electromagnetic valve, measures the swelling height in real time by displacement sensor, and realizes instant display and recording of data in combination with display recording module. In specific implementation, the following procedures need to be operated: prepare and fix the buffer layer sample, ensure that the sample is flat and wrinkle-free, and the water contact area is standardized; calibrate the displacement sensor to ensure measurement accuracy; set the water injection time and total detection time, and control water injection by electromagnetic valve; monitor the swelling height of the sample in real time, and the data is presented through the display recording module; after the detection is completed, the performance of the material is evaluated by analyzing the swelling height data and the generated swelling rate curve.

[0095] It should be noted that the swelling information detection method of the buffer layer sample can correspond to the swelling information detection system of the buffer layer sample. In specific implementation, the experimenters execute each step of the swelling information detection method of the buffer layer sample according to the system structure and function described in the swelling information detection system of the buffer layer sample. For example, the cooperation of the sample containing module and the water injection control module ensures the accurate control of the sample fixing and water injection process; and the displacement detection module and the display recording module jointly ensure the real-time collection and display recording of the swelling height data. With the support of the swelling information detection system of the buffer layer sample, the implementation of the swelling information detection method of the buffer layer sample is more convenient and efficient, and the result is more reliable.

[0096] As an optional solution, the swelling information detection system of the buffer layer sample is applied to a buffer layer swelling height detection scene. In this scene, the swelling performance of the buffer layer is a key indicator for measuring its sealing and insulation performance, and the swelling height and swelling rate directly affect the long-term operation stability of the cable. The detection of the swelling performance of the buffer layer in the related art is mainly completed by manual water injection and vernier caliper measurement. The water injection process relies on manual operation, and the water injection time and water injection amount are difficult to accurately control. Moreover, the timing lag in the instant contact between water and the buffer layer leads to inconsistent test conditions of different samples and poor data repeatability. The swelling height is measured by using a contact tool such as a vernier caliper, which is prone to deformation due to extrusion of the sample, and manual reading has subjective errors, especially it is difficult to capture the rapid change in the initial stage of swelling. There is a lack of automatic recording means, and it is impossible to generate a swelling height-time curve in real time, making it difficult to quantitatively analyze the dynamic change rule of the swelling rate and affecting the scientificity of the detection result.

[0097] The embodiment aims to solve the above problems, and realizes standardized and accurate detection of the expansion performance of the cushioning layer by automatic water injection control and non-contact measurement. The embodiment provides a cushioning layer expansion height detection tool, which comprises a sample containing module, a water injection control module, a displacement detection module, a display recording module and a mounting structure. The sample containing module comprises a cushioning layer container and a punching die with a diameter of 80 mm, and the die is used for fixing the cushioning layer sample to ensure the standardization of the water contact area. The water injection control module is equipped with a 10L water tank, adopts a manual water adding and automatic water injection mode, controls the water injection process through an electromagnetic valve, and can preset the water injection time and automatically stop. The displacement detection module is a laser displacement sensor (or an infrared displacement sensor) with a range of 0-400 mm, which is vertically aligned with the surface of the cushioning layer. The display recording module is a 10-inch touch screen, which can display and automatically record the expansion height data in real time, and generate an expansion rate curve. The mounting structure is a desktop type in a room, and the equipment size is 460 mm long x 400 mm wide x 1100 mm high, the weight is 52 kg, the power supply is 220±10% VAC / 50±0.5 Hz (power 1.2 KW), and the use conditions are that the altitude is less than or equal to 1000 m and the environmental humidity is less than or equal to 85% R.H.

[0098] Optionally, in the embodiment, the cushioning layer sample is fixed in the container through the punching die, water is manually added to the water tank, and then the test is started through the 10-inch touch screen. The electromagnetic valve automatically injects water into the sample and stops according to the set time. The laser displacement sensor synchronously collects the expansion height data, which is transmitted to the touch screen in real time and recorded, and finally generates an expansion height-time curve.

[0099] Further, as shown in the structural schematic diagram of a cushioning layer sample expansion height detection equipment, Figure 2 Optionally, the cushioning layer sample is cut into 100 mm x 100 mm, fixed in the cushioning layer container 206 through the punching die 208, and ensured to be flat and wrinkle-free. Water is manually added to the water tank 202 to the liquid level line, the laser displacement sensor 210 is calibrated to make its laser beam vertically aligned with the center of the sample, and the zero point is set. The water injection time (such as 30 s), the total detection time (such as 300 s) and the data recording interval (1 s / time) are set through the 10-inch touch screen. After starting the test, the electromagnetic valve 204 automatically opens to inject water into the sample, and automatically closes after 30 s. The laser displacement sensor (5) synchronously collects the expansion height data, and the touch screen displays the curve in real time. After the test is completed, the maximum expansion height (such as 25 mm) and the expansion rate curve are automatically generated, the accumulated water in the container is discharged through the water drain valve, and the sample is replaced for repeated test.

[0100] By the examples provided in the present application, a punching die with a diameter of 80 mm is used to fix the sample, ensuring that the water contact area is consistent for each test, solving the error problem caused by non-standard sample fixation in traditional detection; the automatic water injection system can accurately control the water injection time and automatically stop after a set time, realizing "synchronous timing of water contact with the sample instantaneously", and improving the standardization degree of test conditions; the 0~400mm range laser / infrared displacement sensor can capture the expansion height change in real time, with higher detection accuracy than manual measurement, avoiding the interference of contact measurement on the sample; the 10-inch touch screen realizes automatic data recording and curve generation without manual intervention, reducing human reading error and improving test efficiency; the equipment size is suitable for indoor desktop installation, with a weight of 52 kg for easy transportation, and a power of 1.2KW for adaptation to ordinary power supply, suitable for laboratory batch detection scene.

[0101] As an optional solution, the above-mentioned expansion information detection system of the buffer layer sample is applied to the buffer layer expansion performance detection at standard room temperature.

[0102] Place the punching die with a diameter of 80 mm at the bottom of the buffer layer container to ensure that the die and the container fit tightly without looseness. The combination of the container and the die needs to be firmly installed on the equipment platform and kept in a horizontal state.

[0103] Enable the display recording module and enter the displacement sensor calibration interface through the touch screen. Align the sensor probe vertically above the empty space of the buffer layer container, at this time there is no sample and water in the container, set the initial zero point of the sensor. Then, move the probe to directly above the container, confirm that it is vertically downward aligned with the center point of the die, and confirm again that the zero point setting is correct, to ensure that the sensor can accurately measure the expansion height during the experiment.

[0104] Check the water level in the water tank to ensure that the water level is sufficient, usually the water tank capacity is 10L, should be added to two-thirds. Confirm that the electromagnetic valve is connected stably and the circuit is normal. Set the water injection time to 30 seconds on the touch screen of the display recording module to simulate the buffer layer expansion response under the condition of rapid water immersion.

[0105] Optionally, the experimental operation is as follows:

[0106] Sample fixation: cut the buffer layer sample with a diameter of 100 mm, ensure that the sample surface is flat, without damage or foreign matter attached. Place the sample in the punching die, slightly compact to remove air, then put the die together with the sample into the buffer layer container, ensure that there is no gap between the sample and the die and the container wall, and fix it firmly.

[0107] Start detection: set the total detection time to 5 minutes on the touch screen of the display recording module, and set the data recording interval to once per second to capture the rapid change in the initial expansion. After confirming that all parameters are correct, start the automatic detection process through the start button on the touch screen.

[0108] Water Injection and Data Acquisition: After receiving the start signal, the solenoid valve automatically injects water into the container, and the water injection process lasts for 30 seconds. At the same time as water injection begins, the displacement sensor collects the expansion height data of the buffer layer sample in real time. After the data is processed by the display and recording module, it is displayed on the touch screen in real time, forming a curve of expansion height changing over time.

[0109] Data Recording and Result Analysis: After the test, the display and recording module automatically saves all collected expansion height data and generates an expansion rate curve. Researchers can export the data via the touchscreen for detailed analysis, evaluating the differences in expansion performance of different materials and their agreement with theoretical expansion models.

[0110] As an alternative, the expansion information detection system of the above-mentioned buffer layer sample can be applied to the expansion performance test of the buffer layer under high temperature environment.

[0111] The testing equipment was placed in a constant temperature and humidity chamber, with the temperature set at 60°C and the relative humidity at 80% to simulate extreme tropical climate conditions. Sufficient insulation distance was ensured between the equipment and the inner walls of the chamber to prevent heat conduction from affecting the test results.

[0112] Verify that the displacement sensor (laser or infrared) maintains measurement accuracy and stability even at high temperatures. The sensor should be preheated for at least half an hour at the same temperature to adapt to environmental changes and prevent thermal expansion and contraction from affecting the measurement results.

[0113] Considering that high-temperature environments may accelerate moisture evaporation, the water injection volume was appropriately increased, the water injection time was extended to 45 seconds, and the data recording interval was shortened to once every 0.5 seconds, so as to capture the expansion dynamics of materials under high temperatures more intensively.

[0114] Optionally, the basic experimental procedure is similar to that of applying the aforementioned buffer layer sample expansion information detection system to test the expansion performance of the buffer layer at standard room temperature. However, after the sample is fixed, the entire device, along with the sample, needs to be placed in a constant temperature and humidity chamber. Once the ambient temperature stabilizes, the water injection testing process begins. After water injection, the device continues to operate in a high-temperature environment, continuously collecting expansion data until the predetermined total testing time ends.

[0115] Expansion height data and rate curves under high-temperature conditions need to be analyzed separately and compared with test results at standard room temperature to assess the material's expansion performance in high-temperature environments and its impact on the long-term operational stability of the cable. During the analysis, attention should also be paid to the stability of the data curves and the presence of sudden changes or anomalies to gain a deeper understanding of the material's behavior under extreme conditions.

[0116] As an optional solution, the above swelling information detection system of buffer layer samples is applied to evaluate the swelling performance of the buffer layer under different medium water injection conditions, and the swelling performance of the buffer layer material under different water quality (such as pure water, salt water, acidic aqueous solution) conditions is discussed. This helps to evaluate the behavior of the material in different environments, which is of great significance for predicting the durability of the material in various application scenarios.

[0117] Optionally, in this embodiment, according to the test scheme, three different water qualities are prepared, including pure water, salt water with a salt content of 3.5%, and acidic aqueous solution with a pH of 3. Different media are injected into three independent water tanks respectively to ensure the purity and consistency of the media and avoid the influence of the change of the media itself on the test results.

[0118] Optionally, the experimental procedure is as follows:

[0119] Sample preparation: cut the buffer layer sample with a diameter of 100 mm, and divide it into three groups, each group of samples is used for testing of three kinds of media.

[0120] Fixing and initial setting: fix the first group of samples in the punched mold and the buffer layer container according to the steps of embodiment one, set the water injection time to 30 seconds, the total detection time to 5 minutes, and the data recording interval to once per second.

[0121] Perform detection: use pure water, salt water, and acidic aqueous solution for water injection detection in turn, clean and dry the container and sample surface before each detection to avoid contamination between media. During the water injection process, the displacement sensor monitors the swelling height in real time, and the data is processed by the display recording module and then displayed and saved.

[0122] Repeat and compare: after completing the detection of one group of samples, replace the next group of samples and repeat the above steps. After all the detections are completed, compare the swelling height data and swelling rate curves of the samples under different media to analyze the influence of the media on the swelling performance of the material.

[0123] Result analysis: the experimental data shows that the three media have significant differences in the swelling performance of the buffer layer material, among which the material has the fastest swelling speed under acidic aqueous solution, but the stability is poor, the swelling rate under salt water condition is moderate, and the material shows the most stable swelling performance when pure water is injected. These information is crucial for the suitability evaluation of the material in specific environment.

[0124] The buffer layer expansion height detection device of the embodiment can realize standardized and high-precision expansion performance detection, has good expansibility, and can adapt to test requirements under different environmental conditions. Experimental personnel only need to set corresponding detection parameters and environmental conditions according to the operation guide provided by the device, and accurate and reliable test data can be obtained, thereby providing strong support for material selection and performance optimization of cables and other electrical equipment.
