Description

Technical Field

[0001] This utility model relates to the field of conductor de-icing, specifically to a manual de-icing tool for power lines. Background Technology

[0002] In winter, wind farms at high altitudes experience severe condensation and ice buildup on power collection lines and other facilities due to external humidity and temperature. To prevent the conductors and towers from collapsing or breaking under the weight of the ice, manual de-icing is necessary to ensure the stable operation of the power system.

[0003] In related technologies, de-icing is mostly done manually by operating ropes; this method is time-consuming and labor-intensive, and the de-icing is not thorough, resulting in low operational efficiency and potentially causing long-term line outages. Utility Model Content

[0004] In view of this, the present invention provides a manual de-icing tool for power lines to solve the problems mentioned in the background art.

[0005] Firstly, this utility model provides a manual de-icing tool for power lines, comprising:

[0006] The first half-ring and the second half-ring are rotatably connected at the first end of the first half-ring and the first end of the second half-ring.

[0007] The collar assembly includes a first collar and a second collar, wherein the first collar is fixedly connected to the second end of the first half-ring, and the second collar is fixedly connected to the second end of the second half-ring;

[0008] A pull rope is threaded through the inner cavity of the first and second loops;

[0009] When the external force pulls the rope, the second ends of the first half-ring and the second half-ring move closer together. By driving the first half-ring and the second half-ring to rotate and enclose each other, they are fitted onto the wire to be de-iced.

[0010] Beneficial effects: By threading a rope through two loops, operators can close the two semi-rings by pulling the rope, allowing them to pull the rope from the ground without climbing the tower. This enables efficient and rapid de-icing, significantly reducing manpower and operation time. The rotating and opening design allows for quick connection of conductors and completion of de-icing, greatly shortening line downtime, ensuring power grid stability, and is compatible with conductors of different diameters, offering good versatility.

[0011] In some embodiments, scrapers are fixedly provided on the inner ring wall surfaces of the first semi-ring and the second semi-ring, and the scrapers are distributed circumferentially along the inner ring wall surfaces.

[0012] Beneficial effects: The scraper directly contacts the surface of the conductor and removes ice through the mechanical force of the semi-circular closed loop, which is more efficient than pure rope de-icing. The scraper is distributed circumferentially along the inner ring wall to obtain a large area for ice removal, which helps to make the conductor have a smooth surface after ice removal, thereby reducing the probability of subsequent ice adhesion. The operator can pull the rope to apply the scraper to remove ice, which is convenient to operate.

[0013] In some embodiments, at least two scrapers are provided.

[0014] In some embodiments, the scraper is configured as an arc-shaped plate.

[0015] Beneficial effects: The curved plate design matches the curvature of the conductor and fits the conductor surface, which can increase the contact area and improve the ice-scraping efficiency; in addition, it can avoid sharp corners from scratching the conductor insulation layer, reduce the risk of damage, and protect the integrity of the line.

[0016] In some embodiments, the edge region of the scraper is configured as a carbide blade.

[0017] Beneficial effects: Carbide blades have high hardness, allowing them to cut into thick ice layers and effectively enhancing ice-breaking ability, especially suitable for hard ice; the alloy material is wear-resistant, maintaining its sharpness even after long-term use, and is wear-resistant and durable, which helps reduce maintenance frequency.

[0018] In some embodiments, the first collar is fixedly disposed on the inner ring wall of the second end of the first semi-ring, and the second collar is fixedly disposed on the inner ring wall of the second end of the second semi-ring, with either collar and the scraper being spaced apart.

[0019] Beneficial effects: The alternating arrangement of the collar and scraper prevents friction between the pull rope and the scraper during movement, which could lead to adverse wear or jamming; the pull rope transmits the closing force to the end of the half-ring through the collar, ensuring that the scraper and the wire are in uniform contact and are subjected to force. The collar is specifically set on the inner ring wall of the half-ring, which also helps to achieve localized ice scraping and improves the de-icing efficiency.

[0020] In some embodiments, any one of the rings is provided with a wear-resistant ceramic bushing.

[0021] Beneficial effects: The wear-resistant ceramic bushing has good wear resistance and low friction coefficient, which can reduce rope friction loss, prevent breakage caused by repeated pulling, extend the working life of the rope, make the rope slide smoothly, and make the pulling action of the operator smoother.

[0022] In some embodiments, both the first and second semi-rings are stainless steel semi-rings.

[0023] Beneficial effects: Stainless steel has high strength and a stable structure, and it is not easily deformed when subjected to the pressure of ice layers, ensuring long-term reliability; in addition, stainless steel has strong corrosion resistance and can adapt to high humidity and low temperature environments, preventing rust from damaging the device.

[0024] In some embodiments, the manual de-icing tool for the line further includes a hinge assembly, which includes a first hinge, a second hinge, and an adapter shaft. The first hinge is fixed to a first end of the first semi-ring, and the second hinge is fixed to a first end of the second semi-ring. The first hinge and the second hinge are rotatably connected via the adapter shaft.

[0025] Beneficial effects: The use of hinge components provides a stable rotation method, ensuring that there is no offset or jamming during the opening and closing of the two semi-rings, making the device rotate stably and reliably; the hinges can be directly welded to the first end of the semi-ring.

[0026] In some embodiments, the first half-ring has a first overlapping protrusion at its first end, and the second half-ring has a second overlapping protrusion at its first end. A connecting shaft is rotatably mounted on the first overlapping protrusion and the second overlapping protrusion, and the first overlapping protrusion and the second overlapping protrusion are rotatably connected through the connecting shaft.

[0027] Beneficial effects: This design eliminates the need for separate hinge components, reducing the overall weight of the device, making the structure lighter and easier to carry; it also facilitates a one-piece design, resulting in good compactness, reducing protruding parts, and preventing snagging on obstacles during operation.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] In cold regions or under special winter climatic conditions, overhead power lines are highly susceptible to icing. Excessive ice buildup significantly increases the conductor load, leading to increased sag, insufficient clearance to the ground, and even serious accidents such as line breaks and tower collapses, threatening the safe and stable operation of the power grid. Traditional manual de-icing methods (such as climbing poles to break ice) are inefficient, labor-intensive, and dangerous, and require prolonged line shutdowns during operations, resulting in substantial power generation losses.

[0035] This embodiment aims to provide a tool that is easy to operate, safe and efficient, and allows for de-icing operations on the ground without the need for climbing.

[0036] The following is combined with Figure 1 and Figure 2 The following describes embodiments of the present invention.

[0037] According to an embodiment of the present invention, a manual de-icing tool for power lines is provided, comprising a first semi-ring 101, a second semi-ring 102, a collar assembly, and a pull rope 4. The collar assembly includes a first collar 301 and a second collar 302. The first collar 301 is fixedly connected to the second end of the first semi-ring 101, and the second collar 302 is fixedly connected to the second end of the second semi-ring 102. The pull rope 4 passes through the inner cavities of the first collar 301 and the second collar 302.

[0038] Specifically, the first semi-ring 101 and the second semi-ring 102 serve as the main body for de-icing. The first end of the first semi-ring 101 and the first end of the second semi-ring 102 are rotatably connected. When the external force pulls the rope 4, the second end of the first semi-ring 101 and the second end of the second semi-ring 102 can be brought closer to each other. By driving the first semi-ring 101 and the second semi-ring 102 to rotate and enclose each other, they can be sleeved on the wire to be de-iced.

[0039] The manual de-icing tool for power lines provided in this embodiment uses a pull rope 4 threaded through two loops. By pulling the pull rope 4, the operator can drive the two semi-loops to close, allowing the operator to pull the rope on the ground without climbing towers. This enables efficient and rapid de-icing, significantly reducing manpower consumption and operation time. The rotating and opening design allows for quick connection of conductors and completion of de-icing, greatly shortening the downtime of the power line, ensuring the stability of the power grid, and is adaptable to conductors of different diameters, making it highly versatile.

[0040] In the specific implementation process, the conductor or tower to be de-iced is first placed between the first half-ring 101 and the second half-ring 102. Then, one end of the pull rope 4 is passed through the first ring 301 and the second ring 302. The operator pulls both ends of the pull rope 4. Alternatively, the two ends of the pull rope 4 can be tied together. The pull force of the pull rope 4 causes the first half-ring 101 and the second half-ring 102 to rotate and enclose each other, thereby attaching the tool to the conductor or tower to be de-iced.

[0041] In the above description, the first end is the end where the first semi-ring 101 and the second semi-ring 102 are rotatably connected. Figure 1 The upper end is shown; the second end is the end where the first half-ring 101 and the second half-ring 102 move closer or further apart during the rotational stroke. Figure 1 The lower end is shown.

[0042] The manual de-icing tool for power lines provided in this embodiment is lightweight and has a small force-bearing area, allowing operators to pull it with a rope with reasonable effort.

[0043] In some embodiments, the first semi-ring 101 and the second semi-ring 102 are both stainless steel semi-rings, such as 316. Stainless steel has high strength and a stable structure, and is not easily deformed when subjected to ice pressure, ensuring long-term reliability. In addition, stainless steel has strong corrosion resistance and can adapt to high humidity and low temperature environments, preventing rust from damaging the device.

[0044] In some embodiments, a first collar 301 is fixedly disposed on the inner ring wall of the second end of the first semi-ring 101, and a second collar 302 is fixedly disposed on the inner ring wall of the second end of the second semi-ring 102, with either collar or scraper 5 spaced apart. This spaced arrangement of collars and scraper 5 prevents friction between the pull rope 4 and scraper 5 during movement, thus avoiding adverse wear or jamming. The pull rope 4 transmits the closing force to the end of the semi-ring through the collar, ensuring uniform force distribution between the scraper 5 and the wire. The collar's specific placement on the inner ring wall of the semi-ring also facilitates localized ice scraping, improving de-icing efficiency.

[0045] In some embodiments, a wear-resistant ceramic bushing is provided inside any set of rings. The wear-resistant ceramic bushing has good wear resistance and a low coefficient of friction, which can reduce rope friction loss, prevent breakage caused by repeated pulling, extend the working life of the pull rope 4, make the pull rope 4 slide smoothly, and make the pulling action of the operator smoother.

[0046] In an exemplary embodiment, the manual de-icing tool for power lines further includes a hinge assembly. The hinge assembly includes a first hinge 201, a second hinge 202, and a connecting shaft 203. The first hinge 201 is fixed to the first end of the first semi-ring 101, and the second hinge 202 is fixed to the first end of the second semi-ring 102. The first hinge 201 and the second hinge 202 are rotatably connected via the connecting shaft 203. This design uses a hinge assembly to provide a stable rotation, ensuring that the opening and closing process of the two semi-rings is free from offset or jamming, making the device rotate stably and reliably. The hinges can be directly welded to the first end of the semi-rings.

[0047] In other embodiments, the de-icing tool includes an overlapping structure, comprising a first overlapping protrusion and a second overlapping protrusion. The first overlapping protrusion is located at the first end of the first semi-ring 101, and the second overlapping protrusion is located at the first end of the second semi-ring 102. A connecting shaft 203 is rotatably mounted on both the first and second overlapping protrusions, and the first and second overlapping protrusions are rotatably connected via the connecting shaft 203. This design eliminates the need for a separate hinge component, reducing the overall weight of the device, making the structure lighter and easier to carry; it also facilitates a one-piece design, resulting in good compactness, reducing protruding parts, and preventing snagging on obstacles during operation.

[0048] In a further embodiment, scrapers 5 are fixedly provided on the inner ring walls of the first semi-ring 101 and the second semi-ring 102, respectively, and the scrapers 5 are distributed circumferentially along the inner ring walls. The scrapers 5 directly contact the surface of the conductor, and the mechanical force of the semi-ring closure removes the ice, which is more efficient than pure rope de-icing. The circumferential distribution of the scrapers 5 along the inner ring walls provides a large scraping area, which helps to ensure a smooth surface on the conductor after ice removal, reducing the probability of subsequent ice adhesion. The operator can easily pull the rope 4 to apply the scrapers 5 for ice removal.

[0049] Specifically, there are two scrapers 5, which are respectively fixed to the inner ring wall of the first half-ring 101 and the second half-ring 102; of course, one half-ring can be provided with two or more scrapers 5, forming an air-proof groove between two adjacent scrapers 5 in the circumferential direction to facilitate the discharge of ice.

[0050] In some embodiments, the scraper 5 is configured as an arc-shaped plate. The arc-shaped plate design matches the curvature of the conductor and fits the surface of the conductor, which can increase the contact area and improve the ice scraping efficiency; in addition, it can avoid sharp corners scratching the conductor insulation layer, reduce the risk of damage, and protect the integrity of the line.

[0051] In some embodiments, the edge region of the scraper 5 is provided with a carbide blade, such as alloy steel. Carbide blades have high hardness, can cut into thick ice layers, effectively enhance ice-breaking ability, and are especially suitable for hard ice; the alloy material is wear-resistant, remains sharp even after long-term use, is wear-resistant and durable, and helps reduce maintenance frequency.

[0052] Working principle and operation procedure:

[0053] Initial state: The operator is on the ground, holding the pull rope 4. At this time, the first semi-ring 101 and the second semi-ring 102 are in the open state, forming an opening.

[0054] Connecting the wire: The operator lifts and positions the de-icing tool in the open position using an insulated operating rod or similar tool, so that the wire or tower to be de-iced is located in the opening area between the first semi-ring 101 and the second semi-ring 102.

[0055] Closing Tool: The operator pulls down both ends of the pull rope 4 or pre-ties the two ends of the pull rope into a loop and then pulls one end. As the pull rope 4 passes through the inner cavities of the first loop 301 and the second loop 302, it generates an inward pulling force. This force acts on the two loops, causing the second ends of the first half-ring 101 and the second half-ring 102 to move towards each other and approach. Since the first end is the rotating connection point, the two half-rings rotate relative to each other, eventually closing tightly and fitting snugly onto the wire to be de-iced.

[0056] For de-icing:

[0057] If equipped with scraper 5: When the two semi-rings are closed and tightened around the conductor, scraper 5, fixed to the inner wall of the semi-rings, directly contacts the ice layer on the conductor surface. The operator can pull the entire tool back and forth along the length of the conductor or coordinate with the operating lever to efficiently scrape off the ice layer using the mechanical cutting force of scraper 5. The scraped ice chips are discharged through the clearance groove between scrapers 5; the collar assembly itself can also participate in localized ice scraping.

[0058] If there is no scraper 5: the tool uses purely mechanical clamping, and the closed ring applies pressure to the ice, which, together with pulling or vibration, causes the ice layer to break and fall off.

[0059] Completion and Reset: After de-icing is complete, the operator releases the tension of the pull rope 4, or under gravity / slight external force, the two semi-rings can automatically or assistedly open and detach from the guide wire. The tool can then be moved to the next de-icing point for the operation to be repeated.

[0060] This invention addresses the time-consuming and labor-intensive process of de-icing wind farm power collection lines and other facilities. This de-icing tool is convenient to use, saves time and effort, reduces the workload of maintenance personnel, improves line de-icing efficiency, and reduces unnecessary power generation losses caused by the previously lengthy de-icing process.

[0061] The manual de-icing tool for power lines provided by this utility model has the following advantages:

[0062] 1. The remote, labor-saving closing mechanism, consisting of a pull rope 4 and a thimble assembly, allows for ground operation, ensuring safety and efficiency. Operators do not need to climb any poles or towers; they can simply pull the rope from the ground to control the opening and closing of the tool, connect the wires, and perform de-icing operations. This greatly improves operational safety and eliminates the risk of falls from heights.

[0063] 2. Compared to traditional pole-climbing ice-breaking methods, this tool is simple and quick to operate, allowing a single person to complete most of the operations, saving time and effort and significantly increasing efficiency. The closing action requires only a simple pull of the rope, significantly reducing the operator's workload. The de-icing process is highly efficient, greatly shortening the de-icing time at a single point and the overall line downtime, effectively reducing power generation losses caused by de-icing.

[0064] 3. The design of the two semi-rings rotating and opening around the first end allows the tool to be quickly and accurately fitted onto the wire, adapting to any possible swaying of the wire's position.

[0065] 4. The overall structure is compact, especially when using the overlapping structure rotation connection, which further reduces weight and makes it easy for operators to carry and operate in complex terrain. The structure is lightweight and easy to carry.

[0066] 5. The opening and closing design and the semi-ring structure enable it to adapt to wires of different diameters within a certain range, improving the tool's versatility and applicability.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
