Dustproof bird-prevention wire-protection device for inlet hole and outlet hole

Abstract

The invention discloses a dustproof bird-prevention wire-protection device for an inlet hole and an outlet hole. The device provided by the invention comprises an annular plugging device and an annular seal device, wherein the annular plugging device comprises two semi-circle plugging pipes, and the two semi-circle plugging pipes are in movable connection; and a filler is arranged in the annular seal device, the annular plugging device of a matched model is manufactured according to the sizes of the inlet hole and the outlet hole, and the inner wall of the annular plugging device is provided with the annular seal device. when the device is in use, the annular plugging device and the annular seal device are sleeved on the inlet hole and the outlet hole, the annular plugging device comprises two semi-circle plugging pipes, therefore the device can be arranged on the inlet hole and the outlet hole conveniently; when the annular plugging device and the annular seal device are fixed on the inlet hole an the outlet hole, a small hole is pricked on the annular seal device, and since the annular seal device is in vacuum packing, the annular seal device is aerated and expands to seal the inlet and the outlet after the hole is pricked, thereby achieving dustproof, bird-prevention and wire-protection effects.

Description

[0001] technical field [0002] The invention belongs to the technical field of power lines, and in particular relates to a dust-proof and bird-proof wire protection device for inlet and outlet holes. Background technique [0003] In the power line, the diameter of the inlet and outlet holes of the transformer metering box and power distribution cabinet is larger than the diameter of the inlet and outlet wires, resulting in too large diameter of the inlet and outlet holes, which creates a shelter for birds to nest in the metering box and power distribution cabinet. If there is a chance, it will easily cause a short circuit between lines, burning of meters and other equipment, and the heating of the bird's nest may also cause a fire; there is also a long-term contact between the incoming and outgoing lines and the iron metering box, power distribution cabinet, etc., which is easy to cause contact with The insulation layer of wires and cables in contact parts such as metering ...
