Device for measuring height of overhead line

Abstract

The invention discloses a device for measuring the height of an overhead line. The device at least comprises an overhead line observation device which is connected to a vertical angle measuring instrument through an observation device connecting piece. The overhead line observation device and the vertical angle measuring instrument are connected to the side face of a distance measuring device clamp seat through the observation device connecting piece. A laser distance measuring device is installed above the distance measuring device clamp seat. The bottom of the distance measuring device clamp seat is connected to a telescopic bracket through a nut. According to the device for measuring the height of an overhead line, the overhead line observation device and the vertical angle measuring instrument are combined to carry out the accurate measurement of a vertical angle, the laser distance measuring device is used to measure a horizontal distance, through the measured vertical angle and the horizontal distance, a corresponding overhead line height is conveniently, rapidly and accurately calculated, the strength of a field operation is reduced, the electric shock risk in a field operation process is reduced, at the same time, the working efficiency is improved, and the device for measuring the height of an overhead line is especially suitable for measuring a line height in the vertical section measurement of a field overhead line.

Description

technical field [0001] The invention relates to the field of surveying and mapping devices, in particular to a device for measuring the height of overhead lines in the field. Background technique [0002] In the field measurement of the overhead line profile, it is necessary to measure the height of the overhead line along the line on site. In the field of surveying and mapping, the measurement accuracy of the height of the overhead line should reach 0.3m, which requires high precision; at present, only the total station can be used to measure the suspension height to achieve this accuracy. Because the instrument is heavy, it is very inconvenient and inefficient to work in the field , At the same time, the total station measurement requires the use of a prism pole (metal material). When measuring under overhead lines (especially power lines), there is a strong electromagnetic field hazard, and there is a risk of electric shock, which is extremely unsafe. Contents of the in...
