Anti-electrostatic anti-blocking and breaking-free bird thorn

Abstract

The present invention relates to the technical field of bird thorn devices, in particular to an anti-electrostatic anti-blocking and breaking-free bird thorn. The bird thorn comprises a base, a fixingbolt, an inner barrel, an outer barrel, a baffle sheet, needle thorns and an operating rod, wherein the base is in a barrel shape with an upward opening; the center of the lower end of the base is fixedly provided with the fixing bolt; the outer side of the upper end of the base is fixedly provided with the inner barrel with the lower end located on the outer side of the middle of the base; the inner barrel is in a barrel shape with a downward opening; the outer side of the inner barrel is sleeved with the outer barrel with the lower end located on the outer side of the lower end of the bottom; and the outer barrel is in a barrel shape with a downward opening. The bird thorn is reasonable and compact in structure and convenient to use; by arrangement of an upper discharge hole and a lowerdischarge hole, rainwater and gravel dust can be conveniently discharged from the inner barrel and the base; the outer barrel is rotated relative to the inner barrel, and the upper ends of the needlethorns are tilted outwards under the cooperation of an inner positioning hole and an outer positioning hole, so that the needle thorns are unfolded; and the bird thorn has the characteristics of being stable, efficient and long in service life.

Description

technical field [0001] The invention relates to the technical field of anti-bird thorns, and is an anti-static anti-blocking and free-breaking bird thorn. Background technique [0002] With the rapid development of power grid construction, overhead transmission lines continue to extend. These lines are generally distributed in urban and rural areas. Due to the tall, stable and wide towers of high-voltage transmission lines, it is easy for birds to inhabit and move around, especially if birds excrete above the wires. Flashover faults on transmission lines. [0003] At present, the anti-bird thorns used have poor folding effect and are not easy to unfold; and exposed to the outdoors for a long time, rain, snow, gravel and dust will block the inside of the anti-bird thorns, and the bird-proof thorns cannot be folded during maintenance, which affects the service life of the bird-proof thorns; After the existing anti-bird thorns are installed, the staff need to squat down to gat...
