Description

Technical Field

[0001] The present invention relates to the technical field of cable insulation protection, and specifically to an insulation protection device for power lines. Background Art

[0002] The insulation protection of power lines is an important guarantee for the safe operation of the power system. During the long-term operation of power lines, they will be affected by natural environments and human factors, resulting in a decline in insulation performance and even triggering safety accidents. Therefore, during the cable manufacturing process, a process of applying isolation powders (such as talcum powder, mica powder, etc.) on the cable surface or the wire core is usually adopted, mainly used to improve processing performance or enhance insulation.

[0003] In the prior art, the cable is usually directly passed through the isolation powder to make the cable contact the isolation powder. However, during the movement of the cable, if the cable is directly inserted deeply into the powder box, during the cable passing process, the isolation powder will be scraped along the path outside the powder box, and placing it on the surface of the powder box to contact the powder will also cause the powder on its passing path to disperse, resulting in uneven contact. Thus, after the cable is wrapped with an insulating layer, the uneven distribution of the powder inside the cable affects the final performance of the cable. Therefore, an insulation protection device for power lines is proposed to solve the above-mentioned problems. Summary of the Invention

[0015] 3. The power line insulation protection device ensures that the inorganic powder is evenly attached to the outer wall of the cable through the design of dynamic adjustment and flipping mechanism, thereby improving the insulation performance of the cable. The uniform powder layer is located between the insulator and the cable conductor, which can effectively isolate the cable from the external environment and reduce corona discharge and insulation aging.

[0027] Working principle: In the cable manufacturing process, "powdering" usually refers to the process of applying inorganic powders such as talcum powder, mica powder, etc. on the cable surface or wire core, which is mainly used to improve processing performance or enhance insulation. First, the cable to be coated with powder is inserted into the powdering box 1, and then it is wound around the outer walls of the three guide wheels 44 to form an inverted triangle structure, so that the cable can penetrate into the powder to remember the powder coating; When the cable is driven by the external winding device, it will be transmitted to the powder box 1. At this time, the motor 49 is started, and then the rotating rod 46 is driven to rotate, and then the reciprocating wire groove on its outer wall is rotated, and the slider 47 is driven to move left and right, thereby driving the connecting rod 48 to move left and right, and then driving the push block 45 to move left and right, and then the guide wheel 44 installed thereon can be driven to move left and right, which can change the position where the cable contacts the inorganic powder and improve the coating effect. At the same time, when moving to the left and right sides, it contacts the slide bars 41 on both sides respectively, and under the action of the spring 43, the slide bar 41 is pushed up and down, so that the guide wheels 44 on both sides can be driven to move up and down, and cooperate with the middle guide wheel 44, which can further promote the position adjustment of the cable, thereby improving the contact between the cable and the inorganic powder and improving the coating effect; At the same time, when the rotating rod 46 rotates, it will drive the two paddles 64 to rotate, and at this time, they will contact the flipping blades 62, and then the flipping blades 62 will be flipped to rotate, so that the inorganic powder in the powder box 1 is flipped and promoted to adhere to the outer wall of the cable. When the paddles 64 are out of contact with the flipping blades 62, the flipping blades 62 will be reset under the action of the coil spring 63, so that the effect of continuing to flip can be achieved; When the cable moves into the powder box 1, the two movable blocks 31 are pulled closer to each other by the spring 1 34, so that the wiping blocks 32 installed on the two movable blocks 31 are pushed against the outer wall of the cable, so as to wipe the cable to remove water and oil from the outer wall of the cable and avoid contamination of the inorganic powder in the powder box 1; When the cable is attached with powder, in order to make the powder evenly attached to the outer wall of the cable, the cable will come into contact with the soft brush between the brush blocks 51, so that the stubborn powder on the outer wall of the cable can be brushed off, so as to realize the subsequent coating of insulating materials. At the same time, when the rotating rod 46 rotates, it will drive the cam 57 to rotate synchronously, and then push the push rod 55 to move upward. Under the action of the arc-shaped elastic telescopic rod 56, the brush block 51 will be reset downward. Therefore, the brush block 51 can be pushed and deflected around the spherical rod 53, so as to realize the function of deflecting the brush block 51 up and down, changing the brushing angle, and further improving the brushing effect.
