Abstract
Description
Technical Field
[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a power transmission line icing monitoring device. Background Technology
[0002] Global climate change is leading to more frequent extreme weather events, posing challenges to infrastructure, especially the problem of icing on power transmission lines. In winter, ice forms on the surface of power transmission lines, increasing their weight and sag, which affects their electrical performance and may cause line breaks or tower collapses, resulting in large-scale power outages and impacting all aspects of society.
[0003] The power industry traditionally relies on manual inspections and observation stations for icing monitoring, but these methods have limitations. Manual inspections are time-consuming and affected by terrain and weather, making it difficult to monitor transmission lines comprehensively in real time. Observation stations have limited coverage areas and cannot cover a wide range of networks. Both methods lack timeliness and accuracy, making it impossible to detect signs of icing in a timely manner, assess the severity, and provide effective decision support for the power sector to take timely and accurate measures to prevent and mitigate icing disasters.
[0004] Existing icing detection equipment has an unstable energy extraction method and cannot effectively monitor for a long period of time. Utility Model Content

[0016] To facilitate quick assembly and disassembly of the camera module, transmission module, and sensor fusion module, one end of the first sealing cavity and the second sealing cavity are closed structures, while the other end has an opening, and a sealing end cap is detachably connected to the opening.
[0017] To facilitate quick assembly and disassembly of the power supply module, the lower housing has several support blocks that can support both sides of the power supply module. The two sides of the power supply module are detachably connected to the support blocks by several screws.
[0018] To ensure the accuracy of image data collection, the camera module includes at least one high-definition camera and at least one ultra-high-definition camera.
