Problems solved by technology

The traditional warning device is only on the tower or the ground below the line. The construction personnel may only pay attention to the air when carrying out excavator operations, ignoring the existence of warnings on the tower or the ground, and the distance between the crane and the wire is likely to be insufficient.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] Such as Figure 1-Figure 3 As shown, a transmission line warning device includes an insulating sheath 1, a warning sign 2, and a shrink ring 3. A warning sign 2 is set under the insulating sheath 1. The warning sign 2 is used for warning, and the head of the insulating sheath 1 is set Shrink ring 3, shrink ring 3 automatically shrinks insulation sheath 1, power line 4 is set inside insulation sheath 1, load-bearing blocks 6 are set on both sides of warning sign 2, load-bearing blocks 6 prevent warning sign 2 from being blown by wind, shrink ring 3 and A protruding head 5 is set between the load-bearing blocks 6, and the protruding head 5 is used to bind the insulating sheath 1 and the transmission line 4. An infrared detector 8 is set under the warning sign 2, and the infrared detector 8 detects the height of the boom. Set the flashlight 7, the flashlight 7 is used ...

Abstract

An electric transmission line warning device comprises an insulation sheath, a warning board and a retraction ring. The warning board is arranged below the insulation sheath, the retraction ring is arranged on the head portion of the insulation sheath, an electric transmission line is arranged in the insulation sheath, and bearing blocks are arranged on the two sides of the warning board. Flange heads are arranged between the retraction ring and the bearing blocks, an infrared detector is arranged below the warning board, a flash lamp is arranged on the warning board, and a buzzer is arranged on the flash lamp. The electric transmission line warning device has the advantages that the edges of the bearing blocks and the edge of the warning board are all in arc design, and the situation that corner angles are generated, and consequently floating objects and the like in air are possibly wound around the insulation sheath is avoided; a slogan is printed through colored reflecting materials and luminous materials, offline constructors can clearly see the slogan in the daytime and at night through the reflecting materials and the luminous materials, the reflecting materials can reflect dazzling light when a car is irradiated, and a better warning function is achieved.

Description

technical field [0001] The invention relates to the field of transmission line operation and maintenance devices, in particular to a transmission line warning device. Background technique [0002] In recent years, with the development and improvement of the power grid structure, the construction of power lines has made great progress. However, due to the particularity of the geographical location and environmental conditions of the power line, there are many tower points, wide areas, long lines, and are exposed to the wild all year round. In addition to being attacked by severe natural weather, human factors and external force damage cause line trips. , the probability of the line being forced to power outage accidents is on the rise, which cannot but arouse our great attention. Discussing and researching countermeasures to prevent power lines from being damaged by external forces, curb accidents caused by human factors, and ensure safe operation of power grids have become ...
