Under the influence of rapid development of economy and social progress, the demand of electric energy is increasing day by day, and the energy industry, especially the power industry, has the characteristics of ultrahigh voltage, long distance and large-capacity vigorous development. Each power failure causes great loss, and ensuring the reliability of the power system becomes one of the targets of the power system. The power system is used for power generation and transmission transformation, and the power transmission line plays a role in transmitting electric energy, but most of the power transmission lines are erected in the wilderness, are widely distributed, pass through complex terrains and are always exposed in severe natural environments, so that the power transmission lines are also the places with the most faults in the power grid, and whether the power transmission lines can normally run or not directly relates to the safety and stability of the whole power system.

The bird repelling is a world-level problem and is a problem which needs to be solved urgently. The existing bird damage prevention device can be divided into 3 types according to the existing measure principle, such as bird repelling, isolation and guide.

The existing devices have defects more or less, the bird prevention devices used by the existing power transmission line have a plurality of types, but the adaptability of birds is also very strong, and the bird prevention effect is gradually weakened through continuous adaptation habit of the devices. The number of bird nests on the pole tower accounts for nearly seven percent of the total number of the pole tower, which indicates that the existing bird-repelling device has a not ideal use effect, mainly because most devices only adopt a bird-repelling means and lack the capability of scaring birds for a long time, so that the bird-repelling is not favorable.

According to the analysis to the research current situation at home and abroad, the utility model discloses innovation has been carried out from following two angles: on the basis of the existing device, a long-term effective bird repelling device with multiple measures is designed by combining the achievements of the development of the high and new technology industries in recent years; not only considers that the power system is not damaged by birds, but also protects the lives of the birds in the bird repelling process, maintains ecological balance and achieves a harmonious and cozy scene of people and nature.
