Description

A special anti-bird device for transmission lines

technical field

The utility model belongs to the technical field of electric power equipment, in particular to a special anti-bird device for transmission lines.

Background technique

For a long time, the tripping faults of high-voltage transmission lines have been mostly caused by bird activities, such as birds building nests on transmission lines. Since the nests are generally located above the hanging points of insulators, most of the nesting materials are branches, straw, or plastic ropes. etc. Many materials are more than a few pieces of insulators, resulting in insufficient safety distance, which is likely to cause line tripping and power outages; secondly, the excrement of birds around the nest falls on the insulators, which is also likely to cause line tripping and power outages in wet weather. Therefore, Bird activities have a great negative impact on transmission lines. In order to prevent the danger of birds, anti-bird panels are common equipment on high-voltage transmission lines. However, the existing anti-bird devices usually have the problem of poor anti-bird effect.

Contents of the invention

The utility model aims to solve the above-mentioned technical problems, and provides a special anti-bird device for transmission lines with good overall anti-bird effect.

The technical scheme of the utility model is: a special anti-bird device for transmission lines, including a concrete pole, the concrete pole is provided with a transmission line, the transmission line is provided with insulators at intervals, and the top of the insulator is provided with a protective umbrella to protect The outer surface of the umbrella is provided with circular protrusions, and a bird-repelling windmill is installed between the concrete pole and the insulator on the transmission line. There are four fan blades, with through holes on the fan blades, and an arc-shaped bird-proof box near the concrete pole on the transmission line. It is connected with a bird-proof arc surface, the outer surface of the bird-proof arc surface is provided with a lubricant coating, and the top of the concrete pole is provided with a sounder.

Preferably, the U-shaped connecting frame is provided with threaded holes, and the U-shaped connecting frame is fixed to the transmission line by bolts.

Preferably, the U-shaped connecting frame and the anti-bird curved surface are integrally formed.

Preferably, the fan blade is connected to the rotating shaft through bolts.

Preferably, the protective umbrella is welded on the top of the insulator.

The beneficial effects of the utility model are: firstly, by integrating the bird-proof box, the bird-repelling windmill and the bird-repelling sounder, the comprehensive effect of bird-proofing can be improved; at the same time, a protective umbrella is set on the top of the insulator to avoid The short circuit caused by the excrement scattered on the insulator, and the outer surface of the protective umbrella is designed with circular protrusions, which can prevent birds from landing on the protective umbrella; secondly, the bird-proof box is designed in an arc shape, A lubricant coating is provided on the outside of the anti-bird arc surface, which can prevent birds from arbitrarily landing on the anti-bird box, thereby preventing birds from nesting here; Continuous high-frequency sounding prevents birds from getting close to the power line. At the same time, a bird-repelling windmill is also installed. When the birds want to get close to the power line, they will fly away from the power line under the drive of the windmill. The comprehensive effect of bird repelling can be improved by arranging the above different bird repelling devices at intervals on the transmission line.
