[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] The buried pipeline 200, especially the water pipe and heating pipe, is often exposed to the humid and electrochemical environment and is easily affected by corrosion. The buried pipeline 200 adopts cathodic protection, which is a common anti-corrosion technology. The buried pipeline 200 is protected from corrosion by applying a cathode current to the structure of the buried pipeline 200. However, after the buried pipeline 200 is cathodically protected, the ground above the buried pipeline 200 will have an electric potential.

[0040] The traditional detection method is a single probe, handheld detection. During the detection process, the operator needs to constantly lift and put down the detection probe, which has low detection efficiency. At the same time, it cannot effectively reduce the interference of the surrounding environment, and is prone to low detection accuracy.

[0041] For an embodiment of one aspect of the present utility model, please refer to Figure 1 , a cathodic protection potential detection shoe 110 is provided, the cathodic protection potential detection shoe 110 includes a shoe wearing part 116 and a sole part 117, the sole part 117 includes at least two independent accommodating cavities 111, each of the accommodating cavities 111 is provided with a metal electrode 112, and the accommodating cavities 111 are filled with an electrolyte 113, the electrolyte 113 is suitable for electrochemical reaction with the metal electrode 112, each accommodating cavity 111, the metal electrode 112 and the electrolyte 113 form a reference electrode, and the reference electrode is used to detect the potential of the buried pipeline 200.

[0042] According to the cathodic protection potential detection shoe 110 provided by the embodiment of the utility model, at least two independent accommodating cavities 111 are provided on the sole part 117, thereby forming at least two reference electrodes. The potentials measured by different reference electrodes can be mutually verified. While completing the potential detection, the data measured by the reference electrode can be corrected in real time, thereby greatly improving the accuracy of detecting the buried pipeline 200.

[0043] It can be understood that the potentials measured by different reference electrodes can verify each other, and by comparing multiple reference potentials, the reliability and consistency of the detection results can be further ensured.

[0044] It should be noted that, although two independent accommodating cavities 111 are used in the embodiment of the present application and two different reference electrodes are formed, in actual use, the number of reference electrodes can be greater and is not specifically limited here.

[0045] According to an embodiment provided by the utility model, the accommodating cavities 111 are all arranged at the heel position of the sole component 117; or, the accommodating cavities 111 are all arranged at the toe position of the sole component 117; or, at least one of the accommodating cavities 111 is arranged at the heel position of the sole component 117, and at least one of the accommodating cavities 111 is arranged at the toe position of the sole component 117.

[0046] It is understandable that the accommodation chamber 111 is arranged at the heel position to ensure that the shoe is subjected to ground pressure during walking, thereby stably contacting the ground and providing reliable potential detection. The accommodation chamber 111 is arranged at the toe position, which is convenient for people to exert force and improves the sensitivity and accuracy of detection. When at least one of the accommodation chambers 111 is arranged at the heel position of the sole component 117 and at least one of the accommodation chambers 111 is arranged at the toe position, the advantages of both can be combined. During walking, when the detection shoe 110 touches the ground, at least one of the heel position and the toe position contacts the ground, ensuring that at least one of the reference electrodes is in good contact with the ground.

[0047] According to an embodiment provided by the utility model, the height positions of the accommodating cavities 111 are the same. It can be understood that the same height position of the accommodating cavities 111 can ensure that they are at the same height when in contact with the ground, thereby providing a consistent potential detection reference, helping to eliminate potential measurement errors caused by inconsistent heights, and improving the consistency and reliability of the detection results.

[0048] According to an embodiment provided by the utility model, the sole part 117 is provided with a liquid injection hole 118, and the liquid injection hole 118 is connected to the accommodating chamber 111. It can be understood that the liquid injection hole 118 can facilitate the operator to inject the electrolyte 113 into the accommodating chamber 111 to maintain the required ions, for example, when the electrolyte 113 is a copper sulfate solution, the ions are copper ions and sulfate ions.

[0049] In one embodiment, a one-way valve is provided at the injection hole 118 to prevent leakage.

[0050] According to an embodiment provided by the present invention, the metal electrode 112 is a copper electrode, and the electrolyte 113 is a copper sulfate electrolyte 113. Of course, the metal electrode 112 and the electrolyte 113 can also be a combination of other reference electrodes, such as a silver electrode and a silver nitrate electrolyte 113.

[0051] According to an embodiment provided by the utility model, the sole component 117 includes a support pad 1171 , and the support pad 1171 wraps the accommodating cavity 111 , and the support pad 1171 is used to support the shoe wearing component 116 .

[0052] It can be understood that the support pad 1171, as a part of the sole component 117, can effectively support the shoe wearing component 116, and can also provide a protective layer for the accommodating cavity 111, effectively utilizing the space of the sole component 117, and ensuring that the overall structure is compact and stable.

[0053] According to an embodiment of the present invention, the sole component 117 includes a water-permeable pad 1172 , which wraps the accommodating cavity 111 , and a ceramic plug 119 is provided on the contact surface between the accommodating cavity 111 and the water-permeable pad 1172 .

[0054] It is understandable that by increasing the contact performance between the ceramic plug 119 and the ground through the water-permeable pad 1172, the voltage can be effectively conducted to the ions in the electrolyte 113 in the accommodating cavity 111. As a medium for enhancing the contact performance, the water-permeable pad 1172 can adapt to the voltage conduction requirements under different ground conditions, ensuring that the sole component 117 can effectively complete the voltage detection function in various environments.

[0055] The ceramic plug 119 acts as a semipermeable membrane. When the water seepage pad 1172 contacts the ground, the voltage of the buried pipeline 200 is conducted to the electrolyte 113 inside the accommodating cavity 111 through the water seepage pad 1172, thereby better forming a voltage loop, making it easier for the reference electrode to detect the potential of the cathodic-protected buried pipeline 200.

[0056] According to an embodiment provided by the present invention, a wiring port 1173 is provided on the side of the sole component 117 . The number of the wiring ports 1173 corresponds to the number of the metal electrodes 112 . The metal electrodes 112 are connected to the wiring ports 1173 .

[0057] It can be understood that by providing the wiring port 1173 on the side of the sole component 117, the metal electrode 112 can be conveniently connected, which simplifies the assembly process and improves the convenience of operation.

[0058] The wiring port 1173 is arranged on the side to make the whole structure more compact without generating additional protrusions on the top or bottom of the sole component 117, thereby improving the comfort of the sole.

[0059] According to the cathode protection potential detection device provided by the second embodiment of the utility model, please refer to Figure 1 and Figure 2, including the above-mentioned cathode protection potential detection shoe 110 and a host 120. The host 120 is connected to the cathode protection potential detection shoe 110, and the host 120 is used to record and display the potential change of the reference electrode.

[0060] In one embodiment, please refer to Figure 1 , Figure 2 and Figure 4 The cathodic protection potential detection device includes a first detection shoe 1101, a second detection shoe 1102 and a host 120. The first detection shoe 1101 is provided with a first reference electrode 114; the second detection shoe 1102 is provided with a second reference electrode 115. The first reference electrode 114 and the second reference electrode 115 are used to detect the potential of the buried pipeline 200; the host 120 is connected to the first detection shoe 1101 and the second detection shoe 1102, and is used to determine a first potential value of the first reference electrode 114, and is used to determine a second potential value of the second reference electrode 115, and the host 120 is suitable for obtaining a calibration potential value by correcting the first potential value and the second potential value.

[0061] According to the cathodic protection potential detection device of the present application, the first potential value obtained by the first reference electrode 114 and the second potential value obtained by the second reference electrode 115 are corrected by the host 120 to obtain a calibration potential value. While completing the potential detection, the data measured by the reference electrode can be corrected in real time, thereby greatly improving the accuracy of detecting the buried pipeline 200.

[0062] It can be understood that the first detection shoe 1101 and the second detection shoe 1102 can be worn on the left and right feet of the operator, and the operator can detect the potential of the buried pipeline 200 while walking. This real-time monitoring method improves the efficiency of detection and increases the convenience of operation. The operator does not need to stop for detection, thereby saving time and labor costs.

[0063] The host 120 can correct and adjust the detection results in real time by comparing the potential values ​​monitored by the first detection shoe 1101 and the second detection shoe 1102 to eliminate possible errors and interferences, which helps to ensure the accuracy and reliability of the detection results.

[0064] For example, when a serious deviation occurs in the first potential value data at a certain time, it can be considered that the first potential value measured at this position is inaccurate. At this time, the second potential value can be used as a calibration potential value to correct the data measured by the reference electrode. The operator does not need to walk the path of the buried pipeline 200 again, thereby reducing the number of inspections and improving work efficiency.

[0065] For example, the data of the first potential value and the second potential value are relatively close, and the average of the first potential value and the second potential value can be taken to obtain a more accurate calibration potential value.

[0066] According to an embodiment provided by the utility model, the host 120 includes a controller and a correction module, the controller is used to determine a first potential value and a second potential value, and based on the first potential value and the second potential value, determine whether the first reference electrode 114 and the second reference electrode 115 are working normally; the correction module obtains a calibration potential value based on the first potential value and the second potential value.

[0067] It is understandable that the controller can determine whether the first reference electrode 114 and the second reference electrode 115 are functioning normally according to the first potential value and the second potential value. If the potential values ​​are abnormal or inconsistent, the controller can automatically issue an alarm or take appropriate measures, such as notifying an operator or executing an automatic correction procedure, thereby ensuring the accuracy and reliability of the detection device.

[0068] The correction module calculates the calibration potential value using the first potential value and the second potential value. This calibration process can eliminate possible errors and drifts, thereby improving the accuracy and stability of the detection data.

[0069] Specifically, the correction module can make automatic judgments, reducing the possibility of human error, and can quickly respond to and handle abnormal situations during real-time monitoring, improving the reliability and stability of the pipeline corrosion monitoring system.

[0070] According to an embodiment provided by the utility model, there are multiple first reference electrodes 114, and the controller determines whether the first reference electrode 114 is working normally based on the potentials of the multiple first reference electrodes 114, and determines the first potential value when the first reference electrode 114 is working normally.

[0071] It can be understood that multiple first reference electrodes 114 can enhance the robustness and reliability of the system. When the detection data of one of the first reference electrodes 114 is abnormal, the other first reference electrodes 114 can still provide a reliable reference potential. By comparing and analyzing the data of multiple reference electrodes, possible errors in individual electrodes can be eliminated, thereby more accurately determining the first potential value and reducing the possibility of detection failure due to a single fault point.

[0072] The controller determines whether the plurality of first reference electrodes 114 are operating normally based on their potentials, thereby realizing fault detection and self-diagnosis functions.

[0073] According to an embodiment provided by the utility model, there are multiple second reference electrodes 115, and the controller determines whether the second reference electrode 115 is working normally based on the potentials of the multiple second reference electrodes 115, and determines the second potential value when the second reference electrode 115 is working normally.

[0074] Similarly, multiple second reference electrodes 115 can enhance the robustness and reliability of the system. When the detection data of one of the second reference electrodes 115 is abnormal, the other second reference electrodes 115 can still provide a reliable reference potential. By comparing and analyzing the data of multiple reference electrodes, possible errors in individual electrodes can be eliminated, thereby more accurately determining the second potential value and reducing the possibility of detection failure due to a single fault point.

[0075] The controller determines whether the plurality of second reference electrodes 115 are operating normally based on their potentials, thereby realizing fault detection and self-diagnosis functions.

[0076] According to an embodiment provided by the present invention, the host 120 includes a display module 125 for displaying the first potential value, the second potential value and the calibration potential value.

[0077] The display module 125 can display the first potential value, the second potential value, and the calibration potential value in real time, so that the operator can timely understand the potential of the pipeline system. By simultaneously displaying the first potential value, the second potential value, and the calibration potential value on the display module 125, the operator can easily compare and analyze the data. They can compare the differences between these values, evaluate the potential changes of the pipeline system, and take necessary adjustments and measures in a timely manner to ensure the effectiveness of the cathodic protection system.

[0078] According to an embodiment provided by the present utility model, the host 120 includes:

[0079] A positioning module 121, used to record the location information of the detection point;

[0080] A collection module 122, used for collecting a first potential value and a second potential value;

[0081] The storage module 123 is used to store the first potential value, the second potential value, the calibration potential value and the position information of the detection point.

[0082] It can be understood that, through the positioning module 121, the acquisition module 122 and the storage module 123, the operator can easily locate the problem area on the pipeline and carry out maintenance work in a targeted manner, thereby saving time and resources.

[0083] The positioning module 121 may specifically be a satellite positioning module 121 .

[0084] According to an embodiment provided by the utility model, the host 120 also includes an alarm module 124. When the calibration potential value is higher than the set potential value, the alarm module 124 issues an alarm, and the storage module 123 stores the alarm signal of the alarm module 124, the potential data of the detection shoe 110, and the location information of the detection point.

[0085] It is understandable that the alarm module 124 can monitor the potential data of the detection shoe 110, and once the potential data is detected to be higher than the set potential value, an alarm will be triggered. The alarm signal triggered by the alarm module 124, the relevant potential data and the detection point location information will be stored in the storage module 123, providing an important basis for subsequent data analysis and fault diagnosis.

[0086] In one embodiment, the set potential value of the host 120 is -850mV to -1200mV. Of course, the example here is not a limitation to the present application, and the set potential value of the host 120 can also be other.

[0087] According to an embodiment provided by the utility model, the alarm module 124 includes a grounding status alarm 1241 and a self-validity alarm 1242. The grounding status alarm 1241 issues an alarm when a reference electrode of the detection shoe 110 fails, and the self-validity alarm 1242 issues an alarm when the potential data of the detection shoe 110 is higher than a set potential value.

[0088] It is understandable that the grounding state alarm 1241 is used to monitor the state of the reference electrode of the detection shoe 110. Once a reference electrode failure is detected, the grounding state alarm 1241 will sound an alarm. The grounding state alarm 1241 can promptly remind the operator or related personnel of the reference electrode failure, which helps to replace or repair it in time, ensuring the accuracy and reliability of pipeline potential detection.

[0089] Specifically, the grounding state alarm 1241 and the self-validity alarm 1242 may be alarm lights or alarm speakers.

[0090] According to an embodiment provided by the utility model, please refer to Figure 3 and Figure 4 , further comprising a receiver 130 and a connecting wire 140, the receiver 130 comprising a main body 131 and a terminal 132. The main body 131 is electrically connected to the host 120; the terminal 132 is rotatably connected to the main body 131; one end of the connecting wire 140 is connected to the terminal 132, and the other end of the connecting wire 140 is connected to the buried pipeline 200 to be detected.

[0091] It is understandable that the main body 131 of the storage 130 is electrically connected to the host 120, and the main body 131 plays a role in supporting the terminal 132 and the connecting line 140. The terminal 132 is rotatably connected to the main body 131. When a person walks forward, the connecting line 140 is continuously stretched. The rotatable connection of the terminal 132 helps to flexibly adjust the position or direction of the connecting line 140.

[0092] According to an embodiment provided by the present invention, the storage container 130 further includes a retractable mounting belt 133 disposed on the main body 131 , and the mounting belt 133 is suitable for being worn on a human body.

[0093] It is understandable that, by installing the belt 133 , the operator can wear the main body 131 of the container 130 , which makes it convenient for the operator to carry the main body 131 and the connecting line 140 with him.

[0094] The mounting belt 133 may be at least one of a shoulder belt and a waist belt. In one embodiment of the present application, the mounting belt 133 includes a shoulder belt and a waist belt, so that the main body 131 can be worn firmly on the operator.

[0095] According to an embodiment provided by the utility model, the storage container 130 further includes a power supply module (not marked in the figure), which is arranged on the main body 131 and supplies power to the host 120. The power supply module arranged on the main body 131 provides power supply to the host 120, ensuring that the host 120 has a stable and reliable power supply when working.

[0096] The cathodic protection potential detection system provided in accordance with the third aspect of the present invention comprises a buried pipeline 200 and the above-mentioned cathodic protection potential detection shoe 110 , and the cathodic protection potential detection shoe 110 is used to detect the ground potential of the buried pipeline 200 .

[0097] The buried pipeline 200 refers to a pipeline system installed underground for transporting liquids or gases, such as a water pipeline, a natural gas pipeline, etc. These pipelines are susceptible to corrosion in an underground environment, so cathodic protection measures need to be taken to extend their service life.

[0098] The cathodic protection potential detection device is used to monitor the potential change of the ground of the buried pipeline 200 to ensure the effectiveness and stability of the cathodic protection system.

[0099] It should be noted that the cathodic protection potential detection system of the present application includes the above-mentioned cathodic protection potential detection shoe 110, and therefore has all the technical effects of the above-mentioned cathodic protection potential detection shoe 110, which will not be described in detail here.
