Description

Technical Field

[0001] The invention relates to the technical field of power auxiliary equipment, in particular to a bare conductor deicing device for overhead power distribution lines in mountainous areas. Background Art

[0002] In extremely cold regions or low-temperature areas in winter, wires used for power transmission and distribution often have accidents due to icing. When the cable surface is at low temperatures, as rainwater adheres, ice quickly forms, which increases the cable gravity and causes overload on the cable racks at both ends, easily leading to cable breakage and cable rack tipping accidents.

[0003] In traditional technology, manual deicing is mostly used, which is inefficient and risky. With the development of technology, deicing robots are currently mainly used on the market for deicing. They move on the cables through walking parts and quickly deicing through the deicing mechanism installed on them.

[0004] However, existing de-icing robots still mainly rely on their own cutting or crushing components to achieve ice crushing operations. However, in actual use, a single de-icing method is limited in applicable scenarios. For excessively thick ice layers or hanging icicles, it is easy for the robot to be unable to move or to de-ice incompletely, causing the rear walking parts to tilt and slip when walking. In order to solve the above problems, a bare conductor de-icing device for overhead power distribution lines in mountainous areas is provided, which can quickly and effectively remove the ice layer.

[0060] The present invention discloses a de-icing device for bare conductors of mountain distribution overhead lines, and the beneficial effects thereof are as follows:

[0061] 1. The ice removal device for bare conductors of the mountain distribution overhead line can quickly remove ice by setting an integrated ice removal unit and using an ice mass removal mechanism. Then, the ice layer on the cable surface is broken by a knocking and crushing part, and a large amount of broken ice is removed by a ice shoveling part. Finally, the residual ice slag is effectively scraped off by a ice scraping part. Thus, the ice layer on the conductor can be effectively and quickly removed by a combination of means. For conductors with ice masses and thick ice, it can effectively and quickly operate, avoiding subsequent deflection and slipping of the walking wheels.

[0062] 2. The ice removal device for bare conductors of the mountain distribution overhead line adopts an integrated hydraulic control system for the entire integrated ice removal unit. The first power hydraulic cylinder is used to move the movable seats on both sides towards the middle, close to the ice layer of the cable. At the same time, the first power hydraulic cylinder drives the second adjustment hydraulic cylinder to make the bracket flip and adjust the angle of the scraper facing the ice layer. The second power hydraulic cylinder drives the third adjustment hydraulic cylinder to make the double-headed C-shaped frame and the single-headed C-shaped frame move towards the middle and be inserted into each other to form an interlock, and three groups of wear-resistant steel wires are respectively attached to the outer surface of the cable to form three annularly distributed contact points, so as to effectively operate on ice layers of different thicknesses.

[0063] 3. The ice removal device for bare conductors of the mountain distribution overhead line uses the second power hydraulic cylinder to synchronously drive the ice mass removal mechanism, the knocking and crushing part and the ice shoveling part, so that the strengthening cutter head repeatedly pushes forward and backward to cut and remove the ice mass; multiple knocking heads respectively knock the ice layer on the cable up and down from both sides, and the scrapers on both sides repeatedly stretch and retract to remove the ice layer on the cable, so as to ensure the synchronous operation frequency of the ice mass removal mechanism, the knocking and crushing part and the ice shoveling part and effectively cooperate in operation.

[0064] 4. The ice removal device for bare conductors of the mountain distribution overhead line, by designing the knocking and crushing part, as the second execution hydraulic cylinder repeatedly contracts, it drives the triangular frame to slide back and forth. When the triangular frame moves towards the middle, the top of the triangular frame pushes the top of the middle second rotating arm to rotate inwards, and at the same time the bottom of the triangular frame pushes the bottoms of the first rotating arms on both sides to rotate inwards; when the triangular frame moves outwards, the top of the second rotating arm rotates outwards, and the bottoms of the first rotating arms on both sides rotate outwards, so that the knocking heads on the first rotating arm and the second rotating arm can operate in a staggered manner, with a simple structure and good crushing effect.

[0102] Working principle: When the device is in use, the lifting cylinder 134 drives the sliding part 132 to move downward, and then the fixed part 131 is suspended on the surface of the cable, and the two sets of movable seats 22 are located on both sides of the cable. Then, the lifting cylinder 134 drives the sliding part 132 to move upward to cover the opening on one side of the fixed part 131, and the two sets of electric driving wheels 133 are clamped on the surface of the cable. At this time, the equipment loading is completed;

[0103] When in use, a wireless control connection is established with the integrated panel 14 through a remote sensing control switch. At this time, the first power hydraulic cylinder 213 is controlled to contract through the remote sensing control switch, so that it sucks the hydraulic oil inside the first adjusting hydraulic cylinders 215 on both sides, so that the first adjusting hydraulic cylinders 215 contract, thereby driving the movable seats 22 on both sides to move toward the middle, so that the knocking and breaking parts 25 and the ice scraping parts 26 are close to both sides of the outer surface of the cable.

At the same time, in this process, the three groups of wear-resistant steel wires 276 are respectively attached to the outer surface of the cable, so that the three groups of wear-resistant steel wires 276 form three annularly distributed contact points on the outer surface of the cable, as shown in the attached figure. Figure 13 In the state shown, the three contact point areas are H1, H2 and H3 respectively, and then the cross shaft 243 is installed on the connecting member 242 by bolts, so as to complete the equipment work of the entire integrated deicing unit 2;

[0104] At this time, the electric drive walking wheel 133 is started, and at the same time, the second power hydraulic cylinder 28 is started. At this time, the electric drive walking wheel 133 drives the entire device to move along the cable. During the movement, the second power hydraulic cylinder 28 drives the first execution hydraulic cylinder 241, the second execution hydraulic cylinder 256, and the third execution hydraulic cylinder 263 to repeatedly contract. At this time, as the device moves, the strengthening cutter head 244 repeatedly pushes forward and backward to cut and remove the icicles hanging downward on the cable;

[0105] The cable from which the icicles are removed enters below the functional carrier plate 21 and is first broken by the knocking and crushing member 25. As the second execution hydraulic cylinder 256 repeatedly contracts, it drives the tripod 255 to slide back and forth. When the tripod 255 moves towards the middle, the top of the tripod 255 pushes the top of the middle second rotating arm 253 to rotate inward, and at the same time, the bottom of the tripod 255 pushes the bottoms of the two first rotating arms 252 on both sides to rotate inward; when the tripod 255 moves outward, the top of the second rotating arm 253 rotates outward, and the bottoms of the two first rotating arms 252 on both sides rotate outward, so that the multiple knocking heads 259 knock the ice layer on the cable up and down from both sides respectively, so that the ice layer breaks;

[0106] Then the third execution hydraulic cylinder 263 drives the scrapers 265 on both sides to repeatedly extend and retract to scrape the ice layer on the cable, and then the three groups of wear-resistant steel wires 276 are attached to the surface of the cable for further ice scraping, and finally all the ice layers on the surface of the cable are removed. The electric drive walking wheel 133 walks on the cable from which the ice layer has been removed, which is more stable and effectively avoids slipping, so as to realize the rapid and effective ice removal operation on the conductor.
