Description

Technical Field

[0001] This utility model relates to the field of overhead line sag detection technology, specifically a ranging device for measuring the sag attitude of overhead lines. Background Technology

[0002] The sag posture of an overhead line refers to the spatial curve shape formed by the conductor between the suspension points of two adjacent towers under the influence of gravity, tension, and external environmental factors. To ensure that conductor tension, safe distance to ground, and crossing distance meet design requirements, and to prevent accidents such as line breakage, short circuits, or electric shocks due to abnormal sag, a distance measuring device for the sag posture of overhead lines is needed to measure the sag distance. However, current distance measuring devices still have the following shortcomings:

[0003] For example, patent document CN222505367U discloses a device for measuring the sag of overhead conductors in power transmission lines. This device, through the coordinated arrangement of a connecting frame, screw, screw sleeve, first toothed disc, second toothed disc, and limiting assembly, can effectively fix the measuring instrument after adjusting its lateral angle, and the fixation is highly reliable and will not easily loosen. However, its protective mechanism for the testing equipment is not perfect, and it is easily affected by extreme low temperatures during use, making the testing equipment susceptible to damage.
