A wire-abandoning protection pole device for distribution lines

Abstract

The invention discloses a wire discarding and pole protecting device for a power distribution line, comprising an end cover, a sleeve, a fixed arm, a suspension column, a lifting ring, a support rod and a buckle assembly, wherein the upper part of the end cover is connected with an insulator on a utility pole, and the lower part is fixed with the sleeve and the fixed arm; the upper end of the fixed arm is closely attached to the outer wall of the sleeve, and the lower end is vertically adjustably provided with a stopper; the upper end of the suspension column is vertically slidably mounted tothe interior of the sleeve, and the lower end of the suspension column protrudes from the bottom of the sleeve and is connected with the lifting ring; a first elastic device is arranged in the sleeveand is compressed between the top of the suspension column and the bottom of the sleeve; an opening is formed at the bottom of the lifting ring; one end of the support rod is hinged with the lifting ring, and the other end is buckled with the lifting ring through the buckle assembly; and the support rod and the lifting ring are buckled to close the opening of the lifting ring. The wire discardingand pole protecting device in the invention can flexibly adjust the load threshold value of wire detachment, adapt to multi-directional force, is reliable and safe, and can be quickly installed and suitable for wires of different specifications.

Description

technical field [0001] The invention belongs to the technical field of power distribution line mechanical devices, and in particular relates to a line abandonment protection pole device for power distribution lines. Background technique [0002] When the distribution lines of the power grid encounter natural disasters such as typhoons and icing, the loads on the wires exceed the expected value, resulting in frequent disconnection and pole collapse. Some areas cannot supply power in time, which brings great troubles to people's daily life . [0003] Most of the existing abandoned wire protection pole devices are only suitable for one specification of wires, which are not suitable for mass production, and cannot be used repeatedly, which causes a lot of waste of materials, or the operation is complicated during the secondary installation, which is harmful to skilled workers. There are certain requirements, and only one direction of force is considered, and it is not applicabl...

Problems solved by technology

[0002] When the distribution lines of the power grid encounter natural disasters such as typhoons and icing, the loads on the wires exceed the expected value, resulting in frequent disconnection and pole collapse. Some areas cannot supply power in time, which brings great troubles to people's daily life

[0003] Most of the existing abandoned wire protection pole devices are only suitable for one specification of wires, which are not suitable for mass production, and cannot be used repeatedly, which causes a lot of waste of materials, or the operation is complicated during the secondary installation, which is harmful to skilled workers. There are certain requirements, and only one direction of force is considered, and it is not suitable for multi-directional forces. The set critical condition when abandoning the line cannot be adjusted, causing inconvenience in use
