Problems solved by technology

[0002] The high-altitude cables located outdoors have been in the harsh outdoor environment for a long time. They have been exposed to wind, sun, and rain. They are prone to aging after a long time, especially their skins are prone to aging and cracking. Small cracks will also cause corrosion in the rainwater to penetrate and accelerate the high-altitude cables. The aging of the cable reduces its service life, and the high-altitude cable is not easy to lay, and the replacement cost is high, and the reduction of its service life will greatly increase the cost of electricity; currently there is no effective way to solve this problem in the existing technology

Embodiment 1

[0044] see figure 1 , figure 2, a repair device for high-altitude cable insulation aging, including a housing 1 and a swivel 2 rotatably sleeved in the housing 1; the swivel 2 is rotatably sleeved outside the high-altitude cable 3; the swivel 2 It is driven by a motor 11 fixedly installed in the casing 1 to rotate; the middle part of the casing 1 and above the high-altitude cable 3 is provided with a paint chamber 12; The paint filling port of the paint; the bottom of the paint chamber 12 is provided with a discharge port 13 facing the high-altitude cable 3; the discharge port 13 is provided with a solenoid valve 131 for opening and closing the discharge port 13; The waterproof insulating paint inside is extruded from the discharge port 13; the side of the swivel 2 in contact with the high-altitude cable 3 is sequentially arranged along its length direction to use the rotation of the swivel 2 to make the repair device advance along the high-altitude cable 3. Utilize the rot...

Embodiment 2

[0056] see image 3 , Figure 4 The difference between the second embodiment and the first embodiment is that the smoothing part 25 is cylindrical, and its inner surface is provided with a sponge layer 252 for evenly coating the paint on the high-altitude cable 3; the smoothing part 25 and the The fine grinding part 24 is set at intervals and connected by a plurality of connecting rods 253. The distance between the connecting rods 253 is set parallel to each other so that the waterproof insulating paint extruded from the discharge port 13 can fall to the high altitude through the gaps between the connecting rods 253. Cable 3 surface.

Abstract

The invention relates to a repair apparatus and a repair method specific to high-altitude cable insulation layer aging. The repair apparatus comprises a shell and a rotational body rotationally arranged in the shell in a sleeving manner; the rotational body is rotationally arranged outside a high-altitude cable in a sleeving manner; the rotational body is driven by a motor fixedly arranged in theshell to rotate; a material coating cavity is formed in the middle part, positioned above the high-altitude cable, of the shell; a waterproof insulating coating material is mounted in the material coating cavity; a material outlet is formed in the bottom, towards the high-altitude cable, of the material coating cavity; an electromagnetic valve for opening and closing the material outlet is arranged on the material outlet; the waterproof insulating coating material in the material coating cavity is extruded out of the material outlet by a material extrusion material; and a pushing part for enabling the repair apparatus to move forwards along the high-altitude cable through rotation of the rotational body, and a rough grinding part, a fine grinding part and an accurate grinding part for grinding the insulating layer of the high-altitude cable through rotation of the rotational body in sequence, and a uniform coating part for uniformly coating the surface of the high-altitude cable with the waterproof insulating coating material extruded from the material outlet through rotation of the rotational body are arranged one surface, in contact with the high-altitude cable, of the rotationalbody in the length direction in sequence.

Description

technical field [0001] The invention relates to a repair device and a repair method for the aging of the insulating layer of high-altitude cables, belonging to the field of electric equipment. Background technique [0002] The high-altitude cables located outdoors have been in the harsh outdoor environment for a long time. They have been exposed to wind, sun, and rain. They are prone to aging after a long time, especially their skins are prone to aging and cracking. Small cracks will also cause corrosion in the rainwater to penetrate and accelerate the high-altitude cables. The aging of the cable reduces its service life, and the high-altitude cable is not easy to lay, and the replacement cost is high. The reduction of its service life will greatly increase the power cost; there is no effective method to solve this problem in the existing technology. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a repairin...
