Description

High-voltage line deicing device TECHNICAL FIELD

[0001] The present application relates to the technical field of high-voltage line deicing, in particular to a high-voltage line deicing device. BACKGROUND

[0002] The overhead power transmission line known to the inventor usually does not use an insulating layer, but uses air as an insulating medium. When ice layers are attached to high-voltage lines in cold weather, some areas on the outer wall of the high-voltage line have thicker ice layers, some areas have thinner ice layers, and some areas have no ice layers. Due to the uneven thickness of the ice layers, the distribution of the electric field on the high-voltage line is changed, resulting in the formation of points with higher electric field strength in areas with thinner ice layers or no ice layers. When the electric field strength becomes high enough at some points, the ability of air as an insulating medium decreases, and the current jumps over the normal path through air discharge, i.e. flashover occurs.

[0003] The high-temperature arc generated by electrical flashover can damage power equipment on the high-voltage line, not only causing regional power outages, disrupting industrial production, and causing irreparable economic losses, but also igniting fires in areas with flammable materials, increasing the safety risks of personnel and the environment in the area. Therefore, workers have to stand on the lifting platform and use a scraper to remove the ice layer on the high-voltage line after the high-voltage line is powered off. Not only is the efficiency of ice removal low, but it is also time-consuming and labor-intensive, increasing the labor intensity of workers. SUMMARY

[0004] In view of the problems existing in the prior art, the present application is proposed.

[0005] To solve the above technical problems, the present application provides the following technical scheme: a high-voltage line deicing device, comprising a moving assembly comprising a mechanical arm body and a mounting bracket provided on the mechanical arm body; and an ice removal assembly comprising a first ice breaking piece, a ice sweeping piece provided on the first ice breaking piece, and a second ice breaking piece provided on one side of the ice sweeping piece; wherein the ice removal assembly is provided on the moving assembly.

[0006] The present application has the following advantages: by providing a first cutter, a second cutter and a scraper, the worker does not need to stand on the lifting platform and use a scraper to remove the ice layer on the high-voltage line. Not only is the efficiency of ice removal improved, but also the labor intensity of the worker is reduced. By providing a push rod and a cleaning brush, the sharpness of the cutting end of the first cutter and the second cutter is prevented from being reduced, and the cutting efficiency of the first cutter and the second cutter is improved.

DETAILED DESCRIPTION

[0017] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0018] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, it will be appreciated that the present application can be practiced in a variety of ways beyond the specific details set forth herein, which can be practiced in other embodiments and applied to other ways within the scope of the present application and its equivalents. Thus, the present application should not be limited by the embodiments set forth in the following description.

[0019] Second, the "one embodiment" or "an embodiment" as used herein means that a particular implementation can include a particular feature, structure, or characteristic. However, the appearances of "in one embodiment" or "in an embodiment" at different places in the specification do not necessarily all refer to the same embodiment, but can refer to different embodiments.

[0020] Embodiment 1

[0021] Referring to FIGS. 1-8, a first embodiment of the present application provides an ice removing device for high-voltage lines. The device is provided with a first ice breaking member 201, a second ice breaking member 202, and a sweeping member 203. This arrangement has the advantage that workers do not need to stand on a lifting platform to remove ice on the high-voltage lines with a shovel. Not only is the efficiency of ice removal improved, but the labor intensity of workers is also reduced.

[0022] In some embodiments, the moving assembly 100 includes a mechanical arm body 101 and a mounting bracket 102 provided on the mechanical arm body 101. The ice removing assembly 200 includes a first ice breaking member 201, a sweeping member 203 provided on the first ice breaking member 201, and a second ice breaking member 202 provided on one side of the sweeping member 203. The ice removing assembly 200 is provided on the moving assembly 100.

[0023] The first ice breaking member 201 rolls on the top of the high-voltage line, the second ice breaking member 202 rolls on the bottom of the high-voltage line, and the sweeping member 203 rotates on the high-voltage line. Since different high-voltage lines have different heights, the mechanical arm body 101 can adjust the lifting height, thereby improving the fault tolerance of the mechanical arm body 101 when removing ice from the high-voltage line.

[0024] In summary, when the worker adjusts the mechanical arm body 101 and moves the mechanical arm body 101, the mounting bracket 102 on the mechanical arm body 101 drives the first ice breaking member 201 and the second ice breaking member 202 to roll on the high-voltage line, thereby cutting off the ice layer on the outer wall of the high-voltage line. The rolling of the first ice breaking member 201 drives the deflection of the sweeping member 203, thereby further removing the loosened ice layer. This arrangement has the advantage that workers do not need to stand on a lifting platform to remove ice on the high-voltage lines with a shovel. Not only is the efficiency of ice removal improved, but the labor intensity of workers is also reduced.

[0025] Embodiment 2

[0026] Referring to FIGS. 1-8, the second embodiment of the application is based on the previous embodiment, but the first cutter 201b-2, the second cutter 202c-2 and the scraper 203d are provided, so that the worker does not need to stand on the lifting platform to scrape the ice layer on the high-voltage line with a scraper, which not only improves the efficiency of ice scraping, but also reduces the labor intensity of the worker.

[0027] In some embodiments, the first ice breaking part 201 comprises a support rod 201a fixedly connected with the inner wall of the mounting frame 102, and the end of the support rod 201a away from the inner wall of the mounting frame 102 is provided with a first ice cutting roller 201b, and the first ice cutting roller 201b comprises a first roller 201b-3 rotatably connected with the support rod 201a.

[0028] The end of the first roller 201b-3 is provided with a plurality of first fixing rods 201b-1, and the plurality of first fixing rods 201b-1 are uniformly arranged around the axis of the first roller 201b-3, and the outer wall of the first roller 201b-3 is provided with a plurality of first cutters 201b-2.

[0029] The end of the first cutter 201b-2 is fixedly connected with the first fixing rod 201b-1, and the first cutter 201b-2 is provided with a first covering groove matched with the high-voltage line, and the end of the first roller 201b-3 away from the support rod 201a is provided with a connecting rod 201c.

[0030] The end of the connecting rod 201c away from the first roller 201b-3 is provided with a connecting bolt 201d, and the ice sweeping part 203 comprises a sliding ring 203a sleeved with the high-voltage line, and the sliding ring 203a is provided with a threaded groove on one side, and the end of the connecting bolt 201d away from the connecting rod 201c is threadedly connected with the threaded groove.

[0031] The side of the sliding ring 203a close to the first ice cutting roller 201b is provided with a bearing 203b, the outer ring of the bearing 203b is fixedly connected with the sliding ring 203a, and the inner ring of the bearing 203b is provided with a plurality of scrapers 203d uniformly arranged around the axis of the bearing 203b.

[0032] The scraper 203d with the blade abutting against the outer wall of the high-voltage line is curved towards the side opposite to the rotating direction, the scraper 203d is provided with an ice falling hole, and the end of the scraper 203d close to the first cutter 201b-2 is provided with a cleaning brush 203c.

[0033] The support rod 201a is fixedly connected with the inner wall of the mounting frame 102, the push rod motor 202d is fixedly connected with the inner wall of the mounting frame 102, the push rod motor 202d can push the second ice cutting roller 202c to press the high-voltage line, and then the high-voltage line pushes the first ice cutting roller 201b. Since the pressure of the second ice cutting roller 202c on the high-voltage line and the reaction force of the first ice cutting roller 201b on the high-voltage line are opposite in direction, the high-voltage line is clamped, which is beneficial to the cutting of the ice layer on the high-voltage line by the first ice cutting roller 201b and the second ice cutting roller 202c.

[0034] The push rod motor 202d pushes the high-voltage line upward and obliquely, and the support rod 201a pushes the high-voltage line downward and obliquely, which is beneficial to the clamping of the high-voltage line by the first ice cutting roller 201b and the second ice cutting roller 202c, and is also beneficial to the sliding of the first ice cutting roller 201b and the second ice cutting roller 202c on the high-voltage line.

[0035] The first covering groove on the first cutter 201b-2 and the second covering groove on the second cutter 202c-2 can completely cover the outer wall of the high-voltage line, which improves the cutting efficiency of the first cutter 201b-2 and the second cutter 202c-2 on the ice layer. The blade of the scraper 203d is in contact with the outer wall of the high-voltage line, and the ice falling hole on the scraper 203d is convenient for the ice slag to fall through the ice falling hole after the ice layer is scraped off.

[0036] In summary, by setting the first cutter 201b-2, the second cutter 202c-2 and the scraper 203d, starting the push rod motor 202d to push the second ice cutting roller 202c, and then making the high-voltage line push the first ice cutting roller 201b, the first ice cutting roller 201b generates a reaction force on the high-voltage line, forming the clamping of the high-voltage line by the first ice cutting roller 201b and the second ice cutting roller 202c. Then move the mechanical arm body 101 to drive the mounting frame 102 on the mechanical arm body 101 to push the second ice cutting roller 202c and the first ice cutting roller 201b to roll along the high-voltage line. When the second ice cutting roller 202c and the first ice cutting roller 201b roll, the second cutter 202c-2 and the first cutter 201b-2 cut the ice layer on the high-voltage line, so that the ice layer is loosened and falls off.

[0037] The first ice cutting roller 201b pulls the ice sweeping part 203 to slide synchronously while rolling, and the push rod 202b on the second ice cutting roller 202c is deflected under the rolling of the second ice cutting roller 202c. After the push rod 202b is deflected, it is in contact with the scraper 203d and pushes the scraper 203d to deflect. In this way, a plurality of scrapers 203d are pushed by a plurality of push rods 202b to rotate around the axis of the high-voltage line and stick to the outer wall of the high-voltage line. The loose ice layer cut by the first ice cutting roller 201b and the second ice cutting roller 202c is further scraped off, and the ice layer is scraped off by the scraper 203d and falls through the ice falling hole on the scraper 203d. The advantage of this setting is that workers do not need to stand on the lifting platform to use a scraper to remove the ice layer on the high-voltage line. Not only is the efficiency of ice shoveling improved, but the labor intensity of workers is also reduced.

[0038] Embodiment 3

[0039] Referring to FIGS. 1-8, the third embodiment of the present application is based on the previous embodiment, except that the push rod 202b and the cleaning brush 203c are arranged. The advantage of this arrangement is to avoid the ice residues remaining on the cutting ends of the first cutter 201b-2 and the second cutter 202c-2 from causing the cutting ends of the first cutter 201b-2 and the second cutter 202c-2 to be blunt, preventing the sharpness of the cutting ends of the first cutter 201b-2 and the second cutter 202c-2 from being reduced, and improving the cutting efficiency of the first cutter 201b-2 and the second cutter 202c-2.

[0040] In some embodiments, the second ice breaking part 202 includes a push rod motor 202d fixedly connected to the inner wall of the mounting frame 102. The push rod motor 202d is provided with a second ice cutting roller 202c at the end away from the inner wall of the mounting frame 102. The second ice cutting roller 202c includes a second roller 202c-3 rotatably connected to the push rod motor 202d.

[0041] The end of the second roller 202c-3 is provided with a plurality of second fixed rods 202c-1 arranged uniformly around the axis of the second roller 202c-3. The outer wall of the second roller 202c-3 is provided with a plurality of second cutters 202c-2. The end of each second cutter 202c-2 is fixedly connected to the second fixed rod 202c-1.

[0042] The second cutter 202c-2 is provided with a second covering groove matched with the high-voltage line. The second roller 202c-3 is provided with a plurality of positioning rods 202a arranged uniformly around the axis of the second roller 202c-3 at the end away from the push rod motor 202d. The positioning rod 202a is provided with a push rod 202b.

[0043] The scraping knife 203d, which is in contact with the outer wall of the high-voltage line, is bent towards the side opposite to the rotating direction, so that the friction force is increased when the poking rod 202b pushes the scraping knife 203d, and the scraping knife 203d is prevented from slipping when the poking rod 202b pushes the scraping knife 203d. The scraping knife 203d is provided with a cleaning brush 203c at the end close to the first cutting knife 201b-2, and the cleaning brush 203c can clean the cutting end of the first cutting knife 201b-2 and the second cutting knife 202c-2.

[0044] In summary, by setting the toggle lever 202b and the cleaning brush 203c, when the toggle lever 202b pushes the scraper 203d to deflect, the scraper 203d drives the cleaning brush 203c to deflect synchronously, at the same time, the first ice cutting roller 201b and the second ice cutting roller 202c drive the first cutter 201b-2 and the second cutter 202c-2 close to the cleaning brush 203c to resist and press the cleaning brush 203c, so that the cutting end of the first cutter 201b-2 and the second cutter 202c-2 gradually inserts into the cleaning brush 203c, because the cleaning brush 203c deflects around the axis of the high-voltage line following the rotation of the scraper 203d, the first cutter 201b-2 and the second cutter 202c-2 deflect along the axis of the high-voltage line following the rotation of the first ice cutting roller 201b and the second ice cutting roller 202c, when the cleaning brush 203c is close to the second cutter 202c-2, one end of the cleaning brush 203c first resists one end of the second cutter 202c-2, so that the second cutter 202c-2 inserts into and presses the cleaning brush 203c, and the hair of the cleaning brush 203c deflects and bends downward, in this process, the part of the cleaning brush 203c resisting the second cutter 202c-2 sweeps away the ice residues attached to the cutting end of the second cutter 202c-2, so that the ice residues fall from one side of the high-voltage line, and when the hair is reset after leaving the second cutter 202c-2, the ice residues adhered to the hair are shaken off, until the other end of the cleaning brush 203c leaves the other end of the second cutter 202c-2, with the continuous rotation of the scraper 203d driving the cleaning brush 203c to continue to deflect, when one end of the cleaning brush 203c again resists one end of the first cutter 201b-2, the first cutter 201b-2 inserts into and presses the cleaning brush 203c, and the hair of the cleaning brush 203c deflects and bends upward, not only making the cleaning brush 203c shake off the ice residues adhered to the hair after sweeping the second cutter 202c-2, but also in this process, the part of the cleaning brush 203c resisting the first cutter 201b-2 sweeps away the ice residues attached to the cutting end of the first cutter 201b-2, so that the ice residues fall from the other side of the high-voltage line, and when the hair is reset after leaving the first cutter 201b-2, the ice residues adhered to the hair are shaken off, until the other end of the cleaning brush 203c leaves the other end of the first cutter 201b-2, and so on, the advantage of this setting is to avoid the ice residues remaining on the cutting end of the first cutter 201b-2 and the second cutter 202c-2 to blunt the cutting end of the first cutter 201b-2 and the second cutter 202c-2, prevent the cutting efficiency of the cutting end of the first cutter 201b-2 and the second cutter 202c-2 from being reduced, and improve the cutting efficiency of the first cutter 201b-2 and the second cutter 202c-2.
