[0002] A power communication network is a dedicated communication network serving the power system. It primarily connects numerous nodes within the power system, such as power plants, substations, and power dispatch centers, enabling the transmission of various information including voice, data, and images. Like the nervous system of the power system, it serves two main purposes: firstly, it allows for the issuance of power dispatch commands, enabling the dispatch center to precisely control the power generation adjustment of power plants and the equipment operation of substations, ensuring a stable supply and rational distribution of electricity; secondly, it monitors the operating status of power equipment, transmitting equipment parameters and fault information in real time, facilitating timely problem detection and handling by maintenance personnel, and ensuring the safe and efficient operation of the power system.

[0003] However, power communication network equipment inevitably malfunctions during actual operation. In such cases, staff need to use testing instruments to locate the faulty equipment, but this often relies on manual operation. This not only results in low testing efficiency but also makes it difficult to guarantee the accuracy of the testing, hindering the rapid location and resolution of problems and affecting the normal operation of the power communication network and the stable operation of the power system.

Detailed Implementation

[0026] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0027] Example

[0028] Please refer to Figures 1-6A fault location mechanism for a power communication network includes: a three-axis motion mechanism 1; a mounting assembly 2, including a column 201 and a mounting base 202, wherein the column 201 is disposed on the platform of the three-axis motion mechanism 1 and is disposed along the Z-axis direction of the three-axis motion mechanism 1, the top of the column 201 extends above the three-axis motion mechanism 1 and is connected to the mounting base 202; and a detection assembly, including a positioning cylinder 4, a detection head 9 and a drive structure, wherein the positioning cylinder 4 is disposed on the mounting base 202 and can rotate on the mounting base 202, the detection head 9 is disposed inside the positioning cylinder 4, and the drive structure is used to drive the positioning cylinder 4 to rotate.

[0029] In practical application, the positioning mechanism of this application first requires the detection line to pass through the positioning cylinder 4. Then, the three-axis motion mechanism 1 operates, driving the stage to move freely in the X, Y, and Z axes. In this way, the detection head 9 can automatically travel along the length of the detection line and adjust its spatial position to ensure a constant distance from the detection line. Simultaneously, the drive structure forces the positioning cylinder 4 to rotate, enabling the detection head 9 to scan and detect the power communication network lines from all directions and multiple angles. Compared to traditional manual detection methods, the advantages of this positioning mechanism are obvious. It eliminates the inefficiency and inaccuracy of manual operation, greatly improving detection efficiency, shortening detection time, and relying on precise mechanical movement to avoid detection errors caused by human factors, ensuring reliable detection results. Ultimately, it can quickly pinpoint the fault source and ensure the stable and normal operation of the power communication network.

[0030] In a preferred embodiment, the drive structure includes a drive motor 12 and a transmission gear 11. The drive motor 12 is disposed on the mounting base 202, and the transmission gear 11 is disposed on the output shaft of the drive motor 12.

[0031] The outer ring surface of the positioning cylinder 4 is provided with a toothed groove 6 for meshing with the transmission gear 11.

[0032] In the above embodiment, the drive motor 12 serves as a power source, providing stable power output to ensure the positioning cylinder 4 rotates continuously and at a uniform speed. This allows the detection head 9 to perform a smooth, all-around scan, preventing missed detections due to unstable power. Furthermore, the gear meshing transmission offers high precision, allowing for accurate control of the rotation angle and speed of the positioning cylinder 4. When working in conjunction with the three-axis motion mechanism 1 to adjust the position of the detection head 9, it can precisely locate fault points. Compared to other transmission methods or manual rotation, this significantly improves detection accuracy, ensuring efficient and accurate troubleshooting of power communication network faults.

[0033] In a preferred embodiment, the top of the mounting base 202 is provided with a mounting groove, and the two ends of the mounting groove in the length direction respectively penetrate through both sides of the mounting base 202.

[0034] The positioning cylinder 4 is provided with an annular locking platform 3 on its outer ring surface, and the mounting groove is provided with a positioning slot adapted to the annular locking platform 3.

[0035] In the above embodiments, the tight fit between the positioning slot and the annular mounting plate 3 can securely fix the positioning cylinder 4, so that it will not easily shift or shake during the rotation driven by the drive structure and the movement of the three-axis motion mechanism 1, ensuring that the detection head 9 is always in a precise detection position, providing reliable support for the accurate location of fault sources in the power communication network.

[0036] As a preferred embodiment, a distance sensor 10 is also provided on the inner side of the positioning cylinder 4.

[0037] In the above embodiments, when the positioning mechanism is working, the distance sensor 10 can monitor the distance between the detection head 9 and the power communication network line or equipment being tested in real time. Once the distance changes abnormally, such as due to equipment vibration, displacement, or other factors causing the detection head 9 to deviate from the optimal detection distance, the sensor will quickly provide feedback. This allows the operator to fine-tune the position of the detection head 9 in a timely manner through the three-axis motion mechanism 1 based on the feedback, ensuring that the detection head 9 is always within the accurate detection distance range, guaranteeing detection accuracy, and avoiding deviations in detection results caused by improper distance.

[0038] In a preferred embodiment, a cleaning brush 8 is provided inside the positioning cylinder 4, and the cleaning brush 8 is located in front of the detection head 9 in the direction of movement.

[0039] In the above embodiment, a cleaning brush 8 is installed inside the positioning cylinder 4 and is located in front of the detection head 9 in the direction of movement, which has significant advantages. When detecting power communication network lines, the cleaning brush 8 contacts the line first, which can clean the dust, debris and other impurities attached to the line surface, avoiding these impurities from interfering with the detection signal of the detection head 9, ensuring accurate and reliable detection data, and reducing misjudgments caused by external factors.

[0040] In a preferred embodiment, there are multiple cleaning brushes 8, which are spaced apart along the circumferential direction of the positioning cylinder 4.

[0041] In the above embodiments, when actually testing power communication network lines, multiple cleaning brushes 8 can work simultaneously to clean the line surface from different directions. Compared with a single cleaning brush 8, the cleaning range is greatly increased, the coverage is wider, and the cleaning efficiency is greatly improved. It can more thoroughly remove dust, debris and other impurities attached to the line.

[0042] In a preferred embodiment, the plurality of the above-mentioned cleaning brushes 8 are connected to the above-mentioned positioning cylinder 4 via an annular airbag 7.

[0043] In the above embodiments, the annular airbag 7 has a certain degree of elasticity, which can act as a buffer when the cleaning brush 8 contacts the power communication network line, preventing the cleaning brush 8 from scratching or damaging the line due to rigid collision, and effectively protecting the integrity of the line. In addition, when the line surface is uneven or has slight deformation, the airbag can adaptively adjust the angle and contact of the cleaning brush 8 to ensure that the cleaning brush 8 always fits tightly against the line, maintains a good cleaning effect, removes obstacles for the subsequent accurate detection by the detection head 9, improves the reliability and stability of the entire fault source location mechanism, and ensures the smooth progress of power communication network detection operations.

[0044] In a preferred embodiment, the mounting base 202 is provided with a fan 5, which is positioned close to the cleaning brush 8.

[0045] In the above embodiments, while the cleaning brush 8 cleans dust and debris from the surface of the line, the fan 5 operates simultaneously, which can promptly blow the cleaned dust and debris away from the surrounding area of ​​the line. On the one hand, this prevents secondary adhesion and ensures that the cleaned line remains clean, providing good conditions for the accurate detection of the subsequent detection head 9 and avoiding misjudgments due to interference from residual impurities with the detection signal; on the other hand, it maintains the cleanliness of the working area, preventing excessive accumulation of dust and debris from affecting the normal operation of the equipment, extending the service life of the equipment, and ensuring that the entire fault source location mechanism can stably and efficiently perform detection operations on the power communication network.
