[0002] Changes in the operation load and meteorological conditions of a power transmission line can cause changes in the line sag, and excessive sag can easily cause accidents such as phase-to-phase short circuits and other hidden dangers, and can also easily limit the transmission capacity of the line. The traditional inclination measurement method and the ground distance measurement method are easily affected by wind, the topography and geomorphology below the conductor and the growth of vegetation, and the detection results are prone to errors, and therefore have certain defects. Therefore, an overhead power transmission line conductor sag detection device based on Beidou positioning technology is urgently needed.

The utility model adopts a portable tripod and a space measurement technology, can accurately calculate the maximum sag and display the maximum sag in real time, and the measurement device is convenient to store and carry after measurement. However, the portable power transmission and distribution line sag detection device in the above-mentioned document mainly considers how to conveniently store and carry, and does not consider the low monitoring efficiency of the existing conductor sag detection device in use;

However, the power line sag detection device in the above-mentioned document mainly considers how to improve the detection efficiency of the power line sag, and does not consider the inconvenience of adjusting the existing conductor sag detection device in use and the poor flexibility;

[0006] 3、The patent document CN215572870U discloses a power line sag low point detection device, which comprises a sag sliding device, two angle adjusting devices, two infrared distance measuring devices and a controller. The sag sliding device is installed on the power line, and a detection plate is installed on the top of the sag sliding device.

The device can detect the lowest point of the conductor sag and the height of the power cross arm installed on the pole, judge the height difference of the conductor suspension point, and judge whether the power line is installed normally. However, the power line sag low point detection device in the above-mentioned disclosure mainly considers how to judge the height difference of the conductor suspension point and whether the power line is installed normally, and does not consider the problem that the existing conductor sag detection device is not convenient to store when in use.
