Bird-pecking prevention device for extra-high voltage composite insulator

Abstract

The invention discloses a bird-pecking prevention device for an extra-high voltage composite insulator, and relates to the technical field of composite insulators. The bird-pecking prevention device is used for preventing birds from falling on the composite insulator to peck an electric power circuit. A left shell and a right shell sleeve the composite insulator and are bound together through a binding wire, a wire cutting assembly is arranged on each of the left shell and the right shell, the binding wire is cut off through linear movement of blades in the wire cutting assemblies to enable the left shell to be separated from the right shell, and parachutes are arranged in the left shell and the right shell to reduce falling speeds of the left shell and the right shell. Tapered blocks are mounted on the shells, so that angles among the composite insulators can be reduced, and the birds can be prevented from directly falling on the composite insulator to peck the electric power circuit. A remote controller is used for controlling movement of the blades in the wire cutting assemblies to cut the binding wire to achieve separation between the left shell and the right shell, and the separated left shell and the separated right shell fall automatically under the action of gravity, so that manual work of operators for climbing an iron tower to demount the shells is avoided, and danger caused by climbing is further avoided.

Description

technical field [0001] The invention relates to the technical field of composite insulators for electric power construction, in particular to a device applied to composite insulators to prevent birds from standing and pecking power lines. Background technique [0002] In electric power construction work, when the UHV line erection is completed, it cannot be powered on for a long period of time. And the iron tower supporting the power line is relatively high, which is easy to attract birds to stay on the high-altitude power line. Especially in the parts with composite insulators, such as figure 1 As shown, since the angle α between the two composite insulators 1 is relatively large, the large umbrella group 11 protrudes, making it easy for the bird to stand on the composite insulator. Birds that land on composite insulators can easily peck power lines, leaving hidden dangers to the safe operation of lines. Contents of the invention [0003] The object of the present inve...
