Anti-corrosion oil coating device for overhead power transmission wires

Abstract

The invention discloses a rust preventive ointment coating device for an overhead electric power transmission conducting wire. The rust preventive ointment coating device comprises an ointment storage box, a movable pressing plate, an air cylinder fixing rack and an air compressor, wherein ointments are stored in the ointment storage box, the movable pressing plate is movably mounted in the ointment storage box and is in close contact with four walls of the ointment storage box, the movable pressing plate is provided with an ointment transmission hole, an ointment blocking mechanism is mounted on a conducting wire outlet opening and comprise a fixed ring and a rotating ring, the fixed ring is mounted on the conducting wire outlet opening, the rotating ring is mounted in the fixed ring, and the rotating ring can rotate around an axis thereof at high speed in the fixed ring; felt is mounted on a part, positioned close to an inner side, of the inner surface of the rotating ring; a protruding part extends from a part, positioned opposite to the fixed ring, of an outer side of the rotating ring; the protruding part of the rotating ring is connected with an output shaft of an electric motor via a leather belt. By using the rust preventive ointment coating device, the conducting wire can be anointed in a 360 degree manner, ointments can be uniformly smeared, air in the ointment storage box can be timely discharged, and ointment waste can be prevented because excessive ointments can be blocked.

Description

technical field [0001] The invention relates to an anti-corrosion oil coating device, in particular to an anti-corrosion oil coating device for overhead power transmission wires. Background technique [0002] At present, steel-cored aluminum stranded wires are still widely used in overhead transmission lines at home and abroad. Steel-cored aluminum stranded wires have the advantages of simple structure, convenient erection and maintenance, low line cost, and large transmission capacity, but their disadvantages are also obvious. For example, the corrosion rate of steel-cored aluminum stranded wires in coastal salt spray areas or near chemical factories is relatively high, and at the same time, the inner layer and the steel core are in contact with aluminum and are prone to potential corrosion. The reason is that the safe operation of the transmission line is seriously threatened and the service life of the wire is affected. In order to effectively reduce the chemical corrosi...

Problems solved by technology

[0003] At present, it is common for all wire manufacturers to use manual coating of anti-corrosion oil on the wires. This production method has several disadvantages. First, artificial oiling can not guarantee that different operators are not sure about the oiling method, weight, and uniformity. Be consistent; second, for multi-layer oiled wires, each layer needs to be oiled, which increases labor costs; third, manual oiling, it is inevitable that there will be too much oil on a certain section of the wire, and the ointment will fall on the ground or Inside the stranding machine, causing waste of grease and oil pollution of the environment and equipment
