Description

Bird prevention device for power grid TECHNICAL FIELD

[0002] In the power system, the power transmission and distribution line is an intermediate link for ensuring reliable power supply, and the reliability of power supply has an important influence on the power supply reliability of the entire power system. The greatest harm affecting power transmission safety in the power transmission and distribution line is birds, because birds have the characteristics of building nests and inhabiting in high trees in the air. With the development of modernization, high trees are becoming less and less, especially in the northwest region due to climate reasons, so birds usually look for some power transmission towers or power poles to build nests on the top of them. When birds build nests, they will use some branches or even iron wires to cause short circuit, and when a group of birds take off, the phenomenon of short circuit caused by discharge will occur. After the birds build nests, the accumulation of bird droppings will also cause short circuit of insulator strings.

[0003] In the prior art, the Chinese invention patent with the application number CN201610471544.5 discloses a bird damage prevention spacer for preventing birds from building nests on the poles, which comprises an upper fixing part, a lower fixing part, fixing bolts, a mounting block and a thorn. The bottom right side of the upper fixing part is hingedly connected with the top right side of the lower fixing part. The fixing bolts are arranged on the lower fixing part, and the nuts are arranged on the upper fixing part. After the cross arm is placed between the upper and lower fixing parts, the cross arm, the upper fixing part and the lower fixing part are locked by the cooperation of the fixing bolts and the nuts. The semispherical mounting block is fixed on the top of the upper fixing part, the arc surface of the mounting block is a mirror surface, a plurality of studs are arranged on the arc surface of the mounting block, and the thorn is mounted on the studs.

[0004] After the device is installed on the cross arm, the mounting block with mirror surface and the thorn can effectively prevent birds from building nests on the cross arm. However, after the device is used for a long time, the surface of the mounting block will be sticky with sundries, which need to be removed, otherwise the effect of light reflection and bird repelling will be reduced, and the use effect of the device will be reduced. Therefore, the present application is proposed.
