Description

Technical Field

[0001] The utility model relates to the technical field of power transmission line monitoring equipment, in particular to an online monitoring device for the state of a power transmission line conductor. Background Art

[0002] Transmission line status online monitoring equipment is an intelligent system that integrates multimodal sensing, data processing, and wireless transmission technologies. It is designed to monitor and evaluate the operating status of transmission lines in real time, ensuring the reliability and safety of the power system. It includes multiple subsystems, such as image and video monitoring, micrometeorological monitoring, tower tilt monitoring, icing monitoring, insulator leakage current monitoring, conductor temperature monitoring, and windage, galloping, and sag monitoring. These subsystems provide comprehensive monitoring of the power system through front-end data collection and back-end analysis and processing.

[0003] A Chinese patent with announcement number CN215449323U discloses an online monitoring device for the status of a transmission line conductor. It uses a ring on the outside of a support column, one side of the ring is hinged to a first support plate by a second fastening bolt, one side of the first support plate is hinged to a hinged seat by a third fastening bolt, a fourth support plate is fixedly installed on the bottom of one side of the third support plate, a double-headed cylinder is fixedly installed on one side of the third support plate and above the fourth support plate, and both telescopic ends of the double-headed cylinder are fixedly connected to a clamp. This structure is simple and easy to operate, thereby reducing cost investment. In addition, compared with traditional welding methods, this structure is not only easy to install and disassemble, improves convenience of use, and reduces time consumption, but also after installation, the main body of the online monitoring device can be adjusted and moved at will according to the monitoring direction, thereby improving flexibility of use.

[0004] This device uses a bidirectional pneumatic cylinder to move the gripper to secure the monitoring device. A second support and adjustment assembly allows for multi-angle adjustment of the monitoring assembly. However, because the monitoring assembly requires the synchronous movement of the second support and adjustment assembly, it occupies a large space during adjustment, is easily obstructed by other structures, and exhibits poor stability after adjustment. To address these issues, we have developed an online monitoring device for the status of transmission line conductors. Utility Model Content
