Description

Technical Field

[0001] The invention relates to the technical field of line deicing devices, and in particular to an automatic deicing device for overhead high-voltage power transmission lines. Background Art

[0002] According to meteorological observations and transmission line operation experience, generally in the winter or early spring season, when the temperature is between -5 and 0℃, the wind speed is between 1 and 15m / s, if there is dense fog, rain, etc., and the air humidity exceeds 85%, rime will form on the surface of the conductor. If the temperature continues to drop, mixed rime will continue to form outside the rime. When the temperature drops to -15 to -8℃, the other meteorological parameters do not change, and rime will continue to grow.

[0003] After massive searches, it was found that the prior art publication number is CN117060316B, which discloses an automatic ice removal device for overhead high-voltage transmission lines, including a driving unit for moving on the transmission line, a first deicing unit is installed on the right end of the driving unit through an auxiliary plate, and a plurality of second deicing units distributed in a semicircle are connected to the first deicing unit. The first deicing unit cooperates with the second deicing unit to first perform multi-directional local melting treatment on the annularly covered ice and then remove the ice from the surface of the transmission line by knocking at multiple angles, thereby improving the effect of removing ice from the surface of the transmission line.

[0004] Therefore, based on the above search and in combination with the existing ones, after rime or hoarfrost is formed, long icicles are often formed on the outside of the wires. At this time, the weight borne by the high-voltage line steel tower may increase to 10-20 times, which may cause the wires to be broken due to the heavy load, forcing the power supply line to be interrupted. However, the existing equipment is hung as a whole on the outside of the wires during de-icing, which will increase the weight borne by the wires and make it easier to cause power supply line interruption. At the same time, general automatic ice removal devices also need to be equipped with charging base station equipment on the tower, which increases the cost and cannot guarantee that the charging equipment will not cause damage to the charging base station after bad weather and can still work safely.

[0005] In addition, the use of high-temperature heating to remove rime or hoarfrost will cause a water film to form on the outside of the power line. The water film can quickly form an ice layer in a low-temperature environment, which is more conducive to the formation of rime or hoarfrost. Moreover, the use of knocking or hitting may cause physical damage to the wires, such as scratches, dents or breaks. These damages will weaken the mechanical strength of the wires, shorten their service life, and increase the risk of future failures. At the same time, when de-icing wires in busy traffic areas or areas with intensive human activities, falling ice can easily cause damage to surrounding facilities, and in serious cases, cause casualties. For this reason, we propose an automatic ice removal device for overhead high-voltage transmission lines. Summary of the invention

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes an automatic ice removal device for overhead high-voltage transmission lines.

[0036] In a typical implementation of the present application, Figure 1-9 As shown, an automatic ice removal device for overhead high-voltage transmission lines comprises:

[0037] An electric tower 1 is fixed on the ground. A plurality of electric towers 1 are provided. Electric wires 2 are electrically and fixedly connected between the electric towers 1. Ice is frozen on the outside of the electric wires 2, and the ice wraps the outside of the electric wires 2.

[0038] The ice removal device 3 is used to remove ice hanging on the outside of the electric wire 2. The ice removal device 3 includes a drone 4 flying in the air. A mounting frame 5 is fixedly installed on the top of the drone 4. The mounting frame 5 is a U-shaped structure. Two infrared wire detectors 11 are fixedly installed on both sides of the inner wall of the mounting frame 5. The infrared wire detectors 11 on both sides are arranged opposite to each other.

[0039] Specifically, the infrared wire detector 11 is an electronic device for detecting infrared rays. It can identify and locate the source of infrared signals. The infrared wire detector 11 can be used to detect potential intruders or monitor specific areas. The working principle of the infrared wire detector 11 is based on the physical properties of infrared rays. Infrared rays are part of the electromagnetic spectrum and have a longer wavelength than visible light, so the human eye cannot see them directly. Many objects, including the human body, emit infrared radiation. The infrared wire detector 11 identifies the existence and movement of objects by detecting changes in these radiations. At the same time, the infrared wire detector 11 also has the function of penetrating objects to identify the position of the internal wires 2, and can detect the distance to the wires 2, making the flight direction and angle of the drone 4 more accurate.

[0040] More specifically, by setting up the above-mentioned structure, it can be ensured that the mounting frame 5 always moves along the length direction of the wire 2, and at the same time, the distance between the wire 2 and the two sides of the inner wall of the mounting frame 5 is always kept consistent. Through the existing technology, the drone 4 has the functions of hovering in the air and navigation control. At the same time, the infrared wire detector 11 can be used to detect the distance between the mounting frame 5 on both sides of the outside of the wire 2 in real time. The distance data of the infrared wire detector 11 can be used to change the flight path of the drone 4 in real time, so that the distance between the mounting frame 5 on both sides of the outside of the wire 2 is always kept consistent.

[0041] The cutting mechanism 6 is used to cut the ice hanging wrapped on the outside of the electric wire 2. The cutting mechanism 6 is symmetrically arranged on the mounting frame 5. The cutting mechanism 6 includes a cutting shell 12 fixedly connected to the inside of the mounting frame 5. The inside of the cutting shell 12 is slidably connected to a sliding block 13. A cutting motor 18 is fixedly installed on the top of the sliding block 13. The output end of the cutting motor 18 is rotatably connected to a cutting disk 19. The outside of the cutting disk 19 is fixedly connected to a plurality of cutting teeth 20. The cutting mechanism 6 also includes a driving motor 14 fixedly installed on the right side of the inner wall of the cutting shell 12. The output end of the driving motor 14 is fixedly connected to a threaded rod 15. The left end of the threaded rod 15 is rotatably connected to the left side of the inner wall of the cutting shell 12. The top of the sliding block 13 is fixedly connected to a nut slider 16. The nut slider 16 is threadedly screwed on the outside of the threaded rod 15. The cutting mechanism 6 also includes an infrared distance sensor 17. The infrared distance sensor 17 includes a transmitting end and a receiving end. The transmitting end is fixedly installed on the right side of the inner wall of the cutting shell 12, and the receiving end is fixedly installed on the right side of the sliding block 13.

[0042] By setting the above-mentioned structure, the two sides of the ice hanging wrapped on the outside of the electric wire 2 can be cut, so that the two sides of the ice hanging become fragile and easy to break. Specifically, the drone 4 is started. When the four infrared wire detectors 11 on both sides of the inner wall of the mounting frame 5 detect the electric wire 2, and the two sides of the inner wall of the mounting frame 5 are at an equal distance from the outside of the electric wire 2, the drive motor 14 is started. The output end of the drive motor 14 rotates to drive the threaded rod 15 to rotate. The threaded rod 15 rotates inside the nut slider 16 to drive the sliding block 13 to slide on the bottom of the inner wall of the cutting shell 12. The sliding of the sliding block 13 drives the cutting motor 18 to slide. The sliding of the cutting motor 18 drives the cutting disk 19 to slide, so that the two cutting disks 19 on both sides of the mounting frame 5 move relative to each other, and the two cutting motors 18 are started during the movement, so that the two cutting disks 19 rotate to cut the two sides of the ice hanging on the outside of the electric wire 2 close to the inner wall of the mounting frame 5, so that grooves are formed on both sides of the ice hanging.

[0043] It is worth mentioning that the moving distance of the cutting disk 19 can be precisely controlled by detecting the distance between the two infrared wire detectors 11 on the same side and the infrared distance sensor 17 on the same side, which can effectively prevent the cutting disk 19 from cutting the wire 2. At the same time, it can also cut the icicles on the outside of the wires 2 of different diameters according to the wires 2 of different diameters. In addition, the moving distance of the cutting disk 19 on both sides of the mounting frame 5 can be changed respectively according to the change in the distance from the outside of the wire 2 detected by the two infrared wire detectors 11 on both sides of the inner wall of the mounting frame 5, so that the four infrared wire detectors 11 on both sides of the inner wall of the mounting frame 5 detect the wire 2, and when the distance between the two sides of the inner wall of the mounting frame 5 and the outside of the wire 2 is not equal, the icicles on the outside of the wire 2 can still be precisely cut.

[0044] The crushing shell 7 is used to expand and crush the ice hanging after cutting so as to separate it from the outside of the electric wire 2. The crushing shell 7 is fixedly connected to the top of the sliding block 13. The cutting disk 19 rotates inside the crushing shell 7. The upper and lower sides of the cutting disk 19 are slidably connected with support plates 24. The inner wall of the crushing shell 7 is fixedly connected with fixed blocks 21 on both sides. The opposite sides of the two fixed blocks 21 are fixedly installed with double-outlet cylinders 22. The upper and lower sides of the cutting disk 19 are provided with avoidance grooves 23. The two support plates 24 are respectively slidably connected to the inside of the adjacent avoidance grooves 23. The output ends of the tops of the two double-outlet cylinders 22 are fixedly connected to the top support plates 24, and the output ends of the bottoms of the two double-outlet cylinders 22 are fixedly connected to the bottom support plates 24.

[0045] By setting up the above-mentioned structure, the ice hanging can be expanded and crushed by the groove cut by the cutting mechanism 6. Specifically, the sliding block 13 moves to drive the crushing shell 7 to move. When the cutting disk 19 cuts to the inside of the ice hanging outside the wire 2, the two double-outlet cylinders 22 inside the crushing shell 7 are started. The output ends of the tops of the two double-outlet cylinders 22 move upward and drive the support plates 24 at the tops of the adjacent cutting disks 19 to move upward. At the same time, the output ends of the bottoms of the two double-outlet cylinders 22 move downward and drive the support plates 24 at the bottoms of the adjacent cutting disks 19 to move downward, abut against the top and bottom of the inner wall of the groove, and tear and crush the groove. Since the grooves are cut on both sides of the ice hanging, the ice hanging at the grooves is relatively fragile. At this time, applying a supporting force to the grooves can break the ice hanging from the grooves, so that the ice hanging is separated from the outside of the wire 2 and falls off.

[0046] A scraping mechanism 8 is provided at the bottom of the mounting frame 5, and the scraping mechanism 8 is used to scrape long ice hangings. The scraping mechanism 8 includes an arc plate 30 slidably connected to the bottom of the mounting frame 5. The scraping mechanism 8 also includes a scraping motor 26 fixedly installed at the bottom of the mounting frame 5. The output end of the scraping motor 26 is fixedly connected to a scraping disk 27, and the top of the scraping disk 27 is fixedly connected to a scraping rod 28. The bottom of the arc plate 30 is fixedly connected to a scraping block 29, and the scraping rod 28 is slidably connected to the inside of the scraping block 29. A plurality of scrapers 25 are fixedly connected to the top of the arc plate 30, and the plurality of scrapers 25 are arranged at intervals. Both ends of the arc plate 30 are fixedly connected to rubber protective sleeves, and the separated ends of the two rubber protective sleeves are fixedly connected to one side of the adjacent cutting shell 12.

[0047] By setting the above-mentioned structure, the long icicles can be gradually scraped from the bottom in the process of the drone 4 gradually approaching the electric wire 2, so that the two cutting discs 19 can move to the two sides of the electric wire 2. Specifically, the drone 4 gradually flies to the electric wire 2 from the bottom of the electric wire 2. In the process of gradually approaching, when the length of the icicles is too long, the two cutting discs 19 cannot be moved to the two sides of the electric wire 2. At this time, the scraping motor 26 is started, and the output end of the scraping motor 26 rotates to drive the scraping disc 27 to rotate. The rotation of the scraping disc 27 drives the scraping rod 28 to move inside the scraping block 29 and drives the scraping block 29 to move. The movement of the scraping block 29 drives the arc plate 30 to slide back and forth at the bottom of the mounting frame 5. The movement of the arc plate 30 drives a number of scrapers 25 to move, and the icicles that are too long are cut from the bottom, so that the two cutting discs 19 can move to the two sides of the electric wire 2, so that the icicles can be cut;

[0048] More specifically, the scraping motor 26 is started, the scraping disc 27 rotates to drive the scraping rod 28 to move. During the movement of the scraping rod 28, the scraping rod 28 slides inside the scraping block 29. At the same time, the scraping rod 28 drives the scraping block 29 to reciprocate. The reciprocating movement of the scraping block 29 drives the arc plate 30 to reciprocate in a direction perpendicular to the wire 2, thereby driving a number of scrapers 25 to reciprocate.

[0049] It is worth mentioning that while the ice removal device 3 is removing ice along the length direction of the wire 2, the ice that is too long can be cut from the bottom to prevent the ice that is too long from blocking the travel path of the ice removal device 3. In the process of the ice removal device 3 removing ice along the length direction of the wire 2, the long ice will first touch the scraper 25. At this time, the scraping motor 26 is started to make the scraper 25 cut one side of the ice, which can effectively prevent the ice removal device 3 from making hard contact with the ice during the process of removing ice along the direction of the wire 2.

[0050] Ice crushing mechanisms 9 are slidably connected to the left and right sides of the mounting frame 5. The ice crushing mechanisms 9 are used to crush the fallen large pieces of ice. The ice crushing mechanisms 9 include two collecting barrels 31 slidably connected to the mounting frame 5. The bottom of the inner wall of the collecting barrel 31 is rotatably connected to a crushing rod 34. A plurality of leakage holes 36 are provided at the bottom of the collecting barrel 31. A crushing motor 35 is fixedly installed at the bottom of the collecting barrel 31. The output end of the crushing motor 35 is fixedly connected to the bottom of the crushing rod 34. A lifting groove 33 is provided on the outside of the collecting barrel 31. A clamping block 32 is fixedly connected to the outside of the collecting barrel 31. The bottom of the clamping block 32 is clamped to the mounting frame 5. The two collecting barrels 31 are respectively located at the bottom of both ends of the arc plate 30 in the length direction.

[0051] By setting the above structure, large pieces of ice can be broken when de-icing the wires 2 in busy traffic areas or areas with dense human activities, so as to prevent property losses and casualties. Specifically, when de-icing the wires 2 in busy traffic areas or areas with dense human activities, the two collecting barrels 31 are respectively fixed on both sides of the mounting frame 5 through the clamping blocks 32 through the lifting grooves 33. At this time, when de-icing the ice hanging outside the wires 2, the broken ice will enter the inside of the collecting barrels 31 on both sides of the mounting frame 5. At this time, the crushing motor 35 is started, and the output end of the crushing motor 35 rotates to drive the crushing rod 34 to rotate. The crushing rod 34 rotates to crush the crushed ice inside the collecting barrel 31, and the crushed ice leaks out from the leakage hole 36 in the form of slag. At this time, the ice slag no longer has the ability to cause harm and is scattered in the air, which can effectively prevent property losses and casualties.

[0052] More specifically, after the ice is separated from the outside of the electric wire 2 and falls to the top of the arc plate 30, since the top of the arc plate 30 is arranged in an arc shape and the crushed ice is blocked by the inner wall of the mounting frame 5, the crushed ice slides along the inclined direction on both sides of the arc plate 30 to the inside of the two collecting tubes 31, so that it can be collected and crushed in a centralized manner.

[0053] Cleaning cylinders 37 are fixedly mounted on both sides of the inner wall of the mounting frame 5 , the output ends of the two cleaning cylinders 37 are fixedly connected to cleaning arms 38 , and the opposite sides of the two cleaning arms 38 are fixedly connected to cleaning half rings 10 .

[0054] By setting the above-mentioned structure, the outside of the wire 2 can be further cleaned. Specifically, when the ice removal device 3 has cleared the ice on the outside of a small section of the wire 2, the two cleaning cylinders 37 are started. The output ends of the two cleaning cylinders 37 respectively drive the adjacent cleaning arms 38 to move relative to each other, and drive the two cleaning half rings 10 to move relative to each other and gently fit the outside of the wire 2. At this time, when the ice removal device 3 moves along the length direction of the wire 2, the cleaning half ring 10 can scrape off the residual ice on the outside of the wire 2, thereby improving the de-icing effect.

[0055] The working principle of the present invention is as follows: when it is necessary to remove the ice hanging on the outside of the electric wire 2, the drone 4 is started, and the drone 4 gradually flies towards the electric wire 2 from the bottom of the electric wire 2. When the length of the ice hanging is too long during the approaching process, the scraping motor 26 is started, and the output end of the scraping motor 26 rotates to drive the scraping disc 27 to rotate, and the scraping disc 27 rotates to drive the scraping rod 28 to move inside the scraping block 29 and drive the scraping block 29 to move, and the scraping block 29 moves to drive the arc plate 30 to slide back and forth at the bottom of the mounting frame 5, and the arc plate 30 moves to drive a plurality of scrapers 25 to move, and the ice hanging that is too long is cut from the bottom, so that the two cutting discs 19 can move to both sides of the electric wire 2;

[0056] When the four infrared wire detectors 11 on both sides of the inner wall of the mounting frame 5 detect the wire 2, and the distance between the two sides of the inner wall of the mounting frame 5 and the outside of the wire 2 is equal, the driving motor 14 is started, and the output end of the driving motor 14 rotates to drive the threaded rod 15 to rotate, and the threaded rod 15 rotates inside the nut slider 16 to drive the sliding block 13 to slide on the bottom of the inner wall of the cutting shell 12, and the sliding of the sliding block 13 drives the cutting motor 18 to slide, and the sliding of the cutting motor 18 drives the cutting disc 19 to slide, so that the two cutting discs 19 on both sides of the mounting frame 5 move relative to each other, and in the process of moving, the two cutting motors 18 are started to rotate the two cutting discs 19 to cut the two sides of the ice hanging on the outside of the wire 2 close to the inner wall of the mounting frame 5, so that grooves are formed on both sides of the ice hanging;

[0057] At the same time, the movement of the sliding block 13 drives the crushing shell 7 to move. When the cutting disc 19 cuts into the inside of the ice hanging outside the wire 2, the two double-outlet cylinders 22 inside the crushing shell 7 are started, and the output ends of the tops of the two double-outlet cylinders 22 move upward and drive the support plates 24 at the tops of the adjacent cutting discs 19 to move upward. At the same time, the output ends of the bottoms of the two double-outlet cylinders 22 move downward and drive the support plates 24 at the bottoms of the adjacent cutting discs 19 to move downward, abut against the top and bottom of the inner wall of the groove, and tear and break the groove. Since the grooves are cut on both sides of the ice hanging, the ice hanging at the groove is relatively fragile. At this time, applying a support force to the groove can break the ice hanging from the groove, so that the ice hanging is separated from the outside of the wire 2 and falls off.

[0058] When de-icing the electric wires 2 in areas with heavy traffic or dense human activities, the two collecting barrels 31 are respectively fixed on both sides of the mounting frame 5 through the lifting groove 33 through the clamping block 32. At this time, when de-icing the ice hanging on the outside of the electric wires 2, the broken ice will enter the collecting barrels 31 on both sides of the mounting frame 5. At this time, the crushing motor 35 is started, and the output end of the crushing motor 35 rotates to drive the crushing rod 34 to rotate. The crushing rod 34 rotates to crush the crushed ice inside the collecting barrel 31, and the crushed ice is leaked out from the leakage hole 36 into slag. At this time, the ice slag no longer has the ability to cause harm and is scattered in the air, which can effectively prevent property loss and casualties.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
