Bird repelling device and method capable of preventing bird nesting

Abstract

The invention discloses a bird repelling device and method capable of preventing bird nesting and effectively solves the problem that birds nest in bird repellents easily in the prior art. The birds are effectively prevented from entering gap parts and nesting on the bird repellents, and the production cost is reduced. The specific scheme is as follows: a base is connected with a cross arm of a power transmission tower, a plurality of thorns are arranged on the base, one end of each thorn is fixed with the base, the other end is far away from the base, the plurality of thorns are arranged in a radial manner from the upper side of the base to the two sides of the base, and the thorns are different in length. A preferable scheme is that the lengths of the thorns are gradually decreased from the upper side of the base to the two sides of the base.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, in particular to a bird repelling device and method for preventing birds from building nests. Background technique [0002] With the enhancement of people's awareness of loving birds and the country's strict control of guns, the number of birds has increased greatly, while the tall trees and forests available for birds to inhabit are decreasing, forcing birds to land and perch on power transmission line towers. Most of the overhead transmission lines run in the wilderness. It covers a wide area and the ecological environment is volatile. It is undoubtedly affected by bird activities. Bird infestation has seriously threatened the safe operation of the power system, and it is urgent to prevent bird infestation on the line, which must be highly valued by the operation management department and line personnel. [0003] The measures taken to prevent bird damage in the Shandong area a...

Problems solved by technology

[0004] Anti-bird thorns have a good anti-bird effect, but they are prone to rust after a long period of operation. The existing anti-bird thorn products are of poor quality or the installation process is unqualified, which will lead to insufficient opening angle and insufficient elasticity after installation of the bird-proof thorns, making the anti-bird The effect is greatly reduced

[0005] The survey found that birds often make nests on the anti-bird thorns. At present, most of the anti-bird thorns installed on 220kV lines are long anti-bird thorns (the length of a single thorn is 60cm). The bird thorns are the same (about 42 pieces), and the opening angle of the long thorns is smaller than that of the short thorns, resulting in a larger gap near the base and a larger gap between the needles, and birds can easily enter the gaps, making it possible for birds to prevent birds Nest on thorns

[0006] According to the record of the removal of the bird's nest on the line, it was found that birds repeatedly built nests on some towers

Most of these towers are close to waters such as rivers, and the river area is not convenient for staff to climb and inspect. Therefore,
