Nameplate device of electric transmission lines

Abstract

The invention relates to the technical field of subsidiary facilities for electric transmission lines, in particular to a nameplate device for the electric transmission lines. The nameplate device includes a nameplate, a base, a spring pin, a spring and a spring pin cap, wherein the base is provided with a spring pin hole, the spring pin includes a head part and a rod part, the head part of the spring pin consists of a magnetic material, the rod part of the spring pin penetrates through the spring pin hole, and the head part of the spring pin is clamped on one surface of the base; the rod part of the spring pin is sleeved with the spring after penetrating from one end of the spring pin hole and then fixedly connected with the spring pin cap; the spring pin is fixed to the base, one end of the spring abuts against the base, the other end of the spring abuts against the spring pin cap, and the spring stays in a semi-compression state; since the nameplate is provided with the magnetic material, the magnetic material on the head part of the spring pin attracts a magnetic material on the nameplate, and therefore the nameplate can be fixed. Through the structure of the nameplate device, disassembling and assembling of nameplates can be conducted conveniently, and more convenience is provided for replacement.

Description

technical field [0001] The present invention relates to the technical field of ancillary facilities of power transmission lines, and more particularly, to a nameplate device for power transmission lines. Background technique [0002] With the development of society and economy, the demand for electric energy is increasing year by year, and the mileage of transmission lines is also gradually increasing. The vast transmission lines are bound to have a large number of towers as structural supports, and each base tower will have a transmission line nameplate. At present, the nameplate device used on the transmission line is mainly made of hard plastic. The mechanical strength of the nameplate is not high, and it is easy to be damaged under the action of external force, and it is easy to qualitatively change, deform or damage under the action of sunlight and saline-alkali corrosion; and , its connection with the tower structure is extremely simple, and it is only fixed on the ang...

Problems solved by technology

At present, the nameplate device used on the transmission line is mainly made of hard plastic. The mechanical strength of the nameplate is not high, and it is easy to be damaged under the action of external force, and it is easy to qualitatively change, deform or damage under the action of sunlight and saline-alkali corrosion; and , its connection with the tower structure is extremely simple, and it is only fixed on the angle steel or steel frame by simple screws. The stress concentration is obvious at the connection position, and under the washing of rainwater, the screws are easy to rust, and the line nameplate is damaged or lost. Once the nameplate of the line is lost, it is difficult to distinguish the name of the line and the number of the tower. On the other hand, once the nameplate of the line is damaged or lost, the line operation and maintenance personnel need to climb the tower to replace it. It is difficult to work at heights and the disassembly and replacement process is complicated. bring great challenges
