Description

Technical Field

[0001] This utility model relates to power engineering and system maintenance, and in particular to an automatic heating device for preventing cable icing. Background Technology

[0002] Outdoor cables in cold regions are exposed to severe cold for extended periods, making their surfaces prone to ice buildup. This not only increases the cable load, potentially causing tower tilting, but also damages the insulation layer, affecting conductivity stability and, in extreme cases, leading to cable breakage and regional power outages. Automatic cable anti-icing heating devices are a crucial component of outdoor high-voltage cable maintenance systems. They are primarily used to wrap the cable surface and automatically heat it at low temperatures, thus supporting cable transmission maintenance and preventing cable damage from icing in cold, rainy, or snowy weather.

[0003] However, cable lines often need to cross different terrains (such as mountains, plains, and rivers), and different sections often use cables of different specifications and thicknesses to adapt to power transmission capacity and environmental requirements. Traditional anti-icing devices, due to their fixed structure, can only be used with a single type of cable. Maintenance units need to purchase and install corresponding devices separately for different cable specifications, which not only significantly increases equipment procurement costs and inventory pressure, but also prolongs the construction cycle and reduces maintenance efficiency. In addition, the outdoor low-temperature environment is complex and changeable. In addition to static ice condensation, freezing rain may also quickly freeze the cable surface during rain and snow. Traditional devices lack targeted dynamic de-icing and heating coordination designs, making it difficult to respond quickly to changes in ice layers, resulting in unstable anti-icing effects and the risk of cable damage due to icing. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic heating device for preventing cable icing, which aims to improve the problem of being unable to be compatible with cables of different thicknesses and adapt to complex and ever-changing outdoor low temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic heating device for preventing cable icing, comprising a housing and a rotating rod. The housing has an internal groove. A first fixing block is rotatably connected to the outer wall of the rotating rod. A first support column is rotatably connected to the outer wall of the first fixing block. A sliding plate is fixedly connected to the outer wall of the first support column. The outer wall of the sliding plate is slidably connected to the inner wall of the housing. A screw rod is fixedly connected to the outer wall of the rotating rod. A second fixing block is threadedly connected to the outer wall of the screw rod. A first connecting block is rotatably connected to the outer wall of the second fixing block. A second outer ring is fixedly connected to the outer wall of the first connecting block. The outer wall of the second outer ring is rotatably connected to the outer wall of the sliding plate. A second support column is fixedly connected to the outer wall of the sliding plate. A first support rod is rotatably connected to the outer wall of the second support column. A scraping assembly is provided on the outer wall of the first support rod.

[0006] As a further description of the above technical solution: the scraping assembly includes a sliding frame, the inner wall of which is slidably connected to the outer wall of the first support rod, a sliding column is fixedly connected to the outer wall of the sliding frame, a first outer ring is rotatably connected to the outer wall of the sliding column, a fixing column is fixedly connected to the outer wall of the first support rod, a snow removal blade is rotatably connected to the outer wall of the fixing column, a first limiting plate is fixedly connected to the outer wall of the first support rod, a second connecting block is fixedly connected to the outer wall of the second outer ring, and the outer wall of the second connecting block is fixedly connected to the outer wall of the first outer ring.

[0007] As a further description of the above technical solution: a motor is fixedly connected to the inner wall of the outer casing, and a first connecting rod is fixedly installed at the output end of the motor. A first connecting post is fixedly connected inside the first connecting rod. A second connecting rod is rotatably connected to the outer wall of the first connecting post, and a second connecting post is rotatably connected to the inside of the second connecting rod.

[0008] As a further description of the above technical solution: A movable frame is fixedly connected to the outer wall of the second connecting column, and a slide rail is slidably connected to the outer wall of the movable frame. The outer wall of the slide rail is fixedly connected to the inner wall of the outer shell. The upper surface of the sliding plate is fixedly connected to the lower surface of the movable frame, and a triangular heating plate is slidably connected to the lower surface of the sliding plate. A second limiting post is fixedly provided on the outer wall of the triangular heating plate, and a limiting block is fixedly connected to the outer wall of the second limiting post. A fixed frame is slidably connected to the outer wall of the second limiting post, and an electric rotating wheel is provided on the outer wall of the second limiting post.

[0009] This utility model has the following beneficial effects: 1. In this utility model, firstly, rotating the rotating rod causes the screw rod to rotate, which in turn causes the second fixing block to rotate, leading to the rotation of the second outer ring. The sliding column then drives the sliding frame to rotate, which in turn drives the first support rod to begin clamping, thus achieving the function of adjusting the clamping diameter and ensuring compatibility with cables of different thicknesses. This eliminates the need to stock multiple devices for different cable specifications, significantly reducing equipment procurement and inventory costs. Furthermore, during on-site installation, only the rotating rod needs to be adjusted to adapt to the current cable, without the need to replace the entire device, significantly shortening construction time and improving maintenance efficiency. It is particularly suitable for complex line scenarios where multiple cable specifications are mixed and installed.

[0010] 2. In this utility model, the drive motor first drives the first connecting rod to rotate, which in turn drives the second connecting rod to rotate, thereby causing the movable frame to reciprocate on the slide rail. This, in turn, drives the sliding plate to reciprocate, achieving the effect of causing the snow removal blades to reciprocate on the cable surface, improving the de-icing contact rate and reducing the amount of ice and snow residue on the cable. Compared to the limitations of static de-icing in traditional devices, the reciprocating snow removal blades can actively adhere to the cable surface, quickly removing dynamically condensed ice and snow, preventing rapid ice thickening under severe weather conditions such as freezing rain. Simultaneously, the dynamic contact between the snow removal blades and the cable reduces localized ice residue, mitigating cable stress imbalance caused by uneven ice distribution.

[0011] 3. In this utility model, the coordinated design of the reciprocating motion of the triangular heating plate and the sliding plate not only heats the cable surface to prevent icing but also promptly removes residual ice and snow from inside the device. This effectively avoids problems such as component jamming or reduced heating efficiency caused by ice and snow accumulation inside the device, ensuring stable operation of the device in long-term low-temperature environments. At the same time, the heating function acts directly on the cable surface, preventing ice from condensing in the early stages of low temperatures, reducing the workload of the snow removal blades, extending the service life of the device, and reducing maintenance frequency and costs.

[0012] 4. In this utility model, the device's mobility on the cable is achieved through an electric rotating wheel. Traditional anti-icing devices are mostly fixed installations, requiring dense deployment along the cable line to achieve full coverage. However, this device can move autonomously via the electric rotating wheel, allowing a single unit to cover a longer section of the line, significantly reducing the number of devices required and lowering overall investment costs. Simultaneously, the mobility function allows the device to flexibly adjust its operating position, focusing on sections with a high risk of icing, thus improving the targetedness and effectiveness of anti-icing work.

[0015] 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, and 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.

[0016] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an automatic heating device for preventing cable icing, comprising a housing 1 and a rotating rod 3. The housing 1 has a groove 2 inside. A first fixing block 4 is rotatably connected to the outer wall of the rotating rod 3. A first support column 5 is rotatably connected to the outer wall of the first fixing block 4. A sliding plate 9 is fixedly connected to the outer wall of the first support column 5. The outer wall of the sliding plate 9 is slidably connected to the inner wall of the housing 1. A screw rod 6 is fixedly connected to the outer wall of the rotating rod 3. A second fixing block 7 is threadedly connected to the outer wall of the screw rod 6. A first connecting block 8 is rotatably connected to the outer wall of the second fixing block 7. A second outer ring 16 is fixedly connected to the outer wall of the first connecting block 8. The outer wall of the second outer ring 16 is rotatably connected to the outer wall of the sliding plate 9. A second support column 10 is fixedly connected to the outer wall of the sliding plate 9. A first support rod 11 is rotatably connected to the outer wall of the second support column 10. A scraping component is provided on the outer wall of the first support rod 11.

[0017] Through the groove 2 inside the outer casing 1, the rotating rod 3 is rotated. The first fixing block 4 supports the rotating rod 3, and the first support column 5 supports the first fixing block 4 to rotate. The sliding plate 9 fixes the first support column 5. The rotating rod 3 drives the screw rod 6 to rotate. When the screw rod 6 rotates, it drives the first connecting block 8 to rotate through the second fixing block 7. The second outer ring 16 is fixedly connected to the first outer ring 14 through the second connecting block 15. When the first connecting block 8 rotates, it drives the second outer ring 16 to rotate. The second support column 10 supports the first support rod 11 to rotate on the outer wall of the sliding plate 9. The rotation of the second outer ring 16 drives the first support rod 11 to start clamping, realizing the function of adjusting the clamping diameter and achieving the effect of being compatible with cables of different thicknesses.

[0018] Reference Figure 3 and Figure 4 The scraping assembly includes a sliding frame 12, the inner wall of which is slidably connected to the outer wall of the first support rod 11. A sliding column 13 is fixedly connected to the outer wall of the sliding frame 12. A first outer ring 14 is rotatably connected to the outer wall of the sliding column 13. A fixed column 17 is fixedly connected to the outer wall of the first support rod 11. A snow removal blade 18 is rotatably connected to the outer wall of the fixed column 17. A first limiting plate 19 is fixedly connected to the outer wall of the first support rod 11. A second connecting block 15 is fixedly connected to the outer wall of the second outer ring 16. The outer wall of the second connecting block 15 is fixedly connected to the outer wall of the first outer ring 14.

[0019] When the second outer ring 16 rotates, it drives the sliding column 13 to rotate. The sliding frame 12 fixes the sliding column 13, ensuring that when the sliding column 13 is rotated by the second outer ring 16, it can drive the first support rod 11 to rotate through the sliding frame 12 to achieve clamping. The first support rod 11 fixes and supports the fixed column 17. The fixed column 17 supports the adjustment angle of the snow removal blade 18, so that the snow removal blade 18 can fit more closely to the cable surface and reduce the device detachment rate. The first limiting plate 19 restricts the snow removal blade 18 to ensure that the contact surface of the snow removal blade 18 always faces the cable.

[0020] Reference Figure 2 A motor 20 is fixedly connected to the inner wall of the outer casing 1. A first connecting rod 21 is fixedly installed at the output end of the motor 20. A first connecting column 22 is fixedly connected inside the first connecting rod 21. A second connecting rod 23 is rotatably connected to the outer wall of the first connecting column 22. A second connecting column 24 is rotatably connected inside the second connecting rod 23. A movable frame 25 is fixedly connected to the outer wall of the second connecting column 24. A slide rail 26 is slidably connected to the outer wall of the movable frame 25. The outer wall of the slide rail 26 is fixedly connected to the inner wall of the outer casing 1.

[0021] The outer casing 1 serves to fix the motor 20. When the motor 20 is started, the output end of the motor 20 drives the first connecting rod 21 to rotate. The first connecting column 22 supports the rotation of the second connecting rod 23. When the first connecting rod 21 rotates, it drives the second connecting rod 23 to rotate through the first connecting column 22. The second connecting column 24 fixes the second connecting rod 23. The force of the rotation of the second connecting rod 23 is fixed by the second connecting column 24, so that the moving frame 25 can reciprocate on the inner wall of the slide rail 26. The outer casing 1 fixes the slide rail 26. The moving frame 25 drives the sliding plate 9 to reciprocate, so as to drive the snow removal blade 18 to reciprocate on the cable surface, thereby improving the de-icing contact rate and reducing the ice and snow residue rate on the cable.

[0022] Reference Figure 2 and Figure 3 The upper surface of the sliding plate 9 is fixedly connected to the lower surface of the movable frame 25, and a triangular heating plate 27 is slidably connected to the lower surface of the sliding plate 9. The triangular heating plate 27 heats the inside of the outer casing 1. Through the reciprocating motion of the snow removal blade 18, the ice and snow on the surface of the cable fall onto the triangular heating plate 27 and the inner wall of the outer casing 1. Through the reciprocating motion of the sliding plate 9, the ice and snow inside the device are pushed out, reducing the icing rate inside the device.

[0023] Reference Figure 2 and Figure 4 A second limiting post 28 is fixedly installed on the outer wall of the triangular heating plate 27. A limiting block 31 is fixedly connected to the outer wall of the second limiting post 28. A fixing frame 29 is slidably connected to the outer wall of the second limiting post 28. An electric rotating wheel 30 is installed on the outer wall of the second limiting post 28. The triangular heating plate 27 fixes the second limiting post 28, and the limiting block 31 fixes the fixing frame 29, ensuring that the fixing frame 29 will not shift and ensuring its normal operation. The electric rotating wheel 30 drives the device to move on the cable.

[0024] Working principle: When the automatic cable anti-icing heating device is needed, the cable is first placed through the outer wall of the fixing frame 29, and the limiting block 31 restricts the fixing frame 29. Next, the rotating rod 3 is rotated, which drives the screw rod 6 to rotate. The rotation of the screw rod 6 drives the first connecting block 8 to rotate, thereby driving the first support rod 11 to clamp the cable, realizing the function of adjusting the clamping diameter and achieving the effect of being compatible with cables of different thicknesses. Then, the motor 20 is started, which drives the first connecting rod 21 to rotate. The first connecting rod 21 drives the second connecting rod 23 to rotate, and the second connecting rod 23 drives the moving frame 25 to reciprocate on the outer wall of the slide rail 26. This causes the snow removal blade 18 to reciprocate on the cable surface, improving the de-icing contact rate and reducing the ice and snow residue on the cable. Then, the triangular heating plate 27 is activated to heat the ice on the cable surface and inside the device. The sliding plate 9 reciprocates to clean the residue inside the device and reduce the icing rate inside the device. Finally, the electric rotating wheel 30 is activated to drive the device to move on the cable. That is, the device can not only be compatible with cables of different thicknesses, but also reduce the ice and snow residue on the cable.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
