Description

Technical Field

[0001] The utility model belongs to the technical field of power transmission line monitoring, in particular to a transmission line iron tower tilt deformation monitoring device. Background Art

[0002] The phenomenon that the center of the tower deviates from the plumb position due to uneven foundation and settlement is called tower tilt. my country has a wide geographical distribution and complex and diverse geological conditions. When the transmission line passes through unfavorable geological areas such as coal mining areas, soft soil areas, hillsides, desert areas, riverbed areas, etc., the tower tilt will cause unbalanced force on the tower ground wire, causing the tower force to change, resulting in insufficient electrical safety distance, affecting the normal operation of the line. In China, manual inspection is often used to determine the tilt of the tower. This method has a long cycle and poor accuracy, especially when the towers are mostly distributed in remote areas. The use of manual inspection will consume a lot of manpower, material and financial resources, and the long inspection cycle cannot achieve real-time monitoring. Once the tower tilts, it cannot be discovered and solved in time, causing delays and leading to greater safety hazards. Transmission line tower tilt deformation monitoring devices are needed.

[0003] At present, the Chinese patent with the announcement number CN216206272U discloses a transmission line tower tilt monitoring device, including several laser distance measuring devices, which are fixedly installed on the tower and evenly distributed around the tower. The laser distance measuring devices can monitor the distance between the tower base in real time or periodically. The laser distance measuring devices are connected to the host computer circuit and transmit the measured data to the host computer; the installation position of the laser distance measuring device on the tower can measure the distance between the tower base and the tower base. The monitoring device of the utility model is low-cost, practical and convenient, highly reliable, can achieve IP56 dustproof and waterproof level, and uses a wireless module to realize remote real-time monitoring of the tower tilt condition, which greatly saves manpower.

[0004] However, when the above device is in use, it relies on a laser distance measuring device to detect the inclination of the tower. If soil erosion occurs somewhere near the base, it is easy to cause the laser distance measuring device to misjudge, resulting in false alarms and inaccurate monitoring results.
