Description

Technical Field

[0001] The utility model relates to the technical field of bird thorn prevention devices, in particular to an insulated bird thorn prevention device that is easy to shrink. Background Art

[0002] Bird damage is one of the main disasters threatening the safe operation of power transmission lines. With the strengthening of human awareness of natural ecological environment protection, the types and number of birds are gradually increasing, and the range of activities will gradually expand. According to years of operating experience, birds like to roost and build nests at the hanging points of the cross-arm insulators of overhead transmission line towers. When birds roost at the hanging points, when they defecate, the bird droppings will short-circuit some insulators near the hanging points, causing insufficient electrical distance between the line conductors and flashover discharge to ground, causing the line to trip. When birds build nests in dangerous parts such as above the insulator hanging points, the materials used to build the bird's nests are mostly branches, thatch, plastic belts, cloth strips, etc. The grass or cloth strips on the bird's nests droop and short-circuit the insulator string, which can easily cause line tripping failures in humid weather. Therefore, it is necessary to develop an easy-to-install anti-bird thorn.

[0003] However, the common bird-proof spikes on the market still have the following problems: the general bird-proof spikes have a relatively large area, which makes it difficult to carry during installation, and most bird-proof spike devices are fixedly connected, which makes installation and disassembly difficult and inconvenient for maintenance. In view of the above problems, an innovative design is carried out on the basis of the original bird-proof spikes. Utility Model Content
