Abstract
Description
Technical Field
[0001] This utility model relates to the field of power line de-icing technology, and in particular to a power transmission line de-icing device and a power transmission line inspection robot. Background Technology
[0002] Power transmission lines freeze in winter, especially after rain or snow, increasing their weight and making them more vulnerable to accidents such as line breaks or collapses. Therefore, timely and effective de-icing is essential. Currently, both domestically and internationally, de-icing of power transmission lines mainly employs two traditional methods: manual tapping and high-current thermal melting. However, both methods have limitations. Manual tapping is labor-intensive, inefficient, and poses safety hazards; while high-current thermal melting can be automated, it consumes a lot of energy, carries a risk of damaging the transmission lines, and is costly. Therefore, existing de-icing technologies are inefficient and ineffective, failing to meet practical needs.
[0003] Existing de-icing devices for power transmission lines also have some structural design flaws. For example, the design is not reasonable enough to clean the outer circumference of the power line from all angles, thus failing to completely remove the ice layer and resulting in poor de-icing performance. Furthermore, existing devices lack flexibility when installed with drones or inspection robots, and are easily obstructed by obstacles such as vibration dampers and insulators on the line, leading to low de-icing accuracy and inefficient de-icing operations.

[0032] Combination Figures 1 to 3The first aspect of this utility model provides a power transmission line de-icing device, including a housing 1, a drive assembly 2, a transmission assembly 3, and a de-icing assembly 4; the drive assembly 2 drives the de-icing assembly 4 to rotate through the transmission assembly 3. The drive assembly 2, the transmission assembly 3, and the de-icing assembly 4 are disposed inside the housing 1. The housing 1 can protect the internal structure from damage and prevent ice or water from entering the de-icing device. The drive assembly 2 drives the transmission assembly 3 to rotate, and the transmission assembly 3 causes the de-icing assembly 4 to rotate around the power transmission line, thereby completing the de-icing work of the power transmission line. Furthermore, the transmission assembly 3 includes a drive gear and a driven gear 33, and the de-icing assembly 4 includes a de-icing ring 41 and a de-icing blade 42. The driven gear 33 is sleeved on the outside of the de-icing ring 41, and the de-icing blade 42 is disposed on the inside of the de-icing ring 41. The drive gear is connected to the output end of the drive assembly 2 and meshes with the driven gear 33. The drive assembly 2 drives the drive gear to rotate, and the meshing of the drive gear and driven gear 33 drives the de-icing ring 41 to rotate. The de-icing effect is achieved by rotating the de-icing blade 42 on the inside of the de-icing ring 41. The top of the housing 1 is provided with a first opening 1a, the driven gear 33 is provided with a second opening 33a, and the de-icing ring 41 is provided with a third opening 41a. The widths of the first opening 1a, the second opening 33a, and the third opening 41a are the same, and the second opening 33a and the third opening 41a face the same direction. With this configuration, the first opening 1a is positioned at the top of the housing 1, facilitating the installation of the de-icing device from below the power line. Simultaneously, the opening design avoids obstacles such as vibration dampers on the line. The first opening 1a, the second opening 33a, and the third opening 41a have the same width. During the installation of the de-icing device, the orientation of the second opening 33a and the third opening 41a aligns with that of the first opening 1a, improving the installation efficiency of the de-icing device. Furthermore, the identical orientation of the second opening 33a and the third opening 41a ensures reliable connection between the driven gear 33 and the de-icing ring 41 throughout the de-icing process. Moreover, during the de-icing rotation, when encountering obstacles on the power line, the orientation of the second opening 33a and the third opening 41a simultaneously aligns with that of the first opening 1a, ensuring the de-icing device passes smoothly through the obstacles, making the de-icing process more continuous and improving de-icing efficiency.
[0033] It should be noted that the specific widths of the first opening 1a, the second opening 33a, and the third opening 41a are not limited here, nor are the specific structure and size of the de-icing blade 42. They can be flexibly set according to the size of the power line requiring de-icing, as long as they can be installed on the power line and achieve the de-icing effect through the de-icing blade 42. The specific shape of the housing 1 is also not limited. In a preferred embodiment, the housing 1 is configured as an annular shell located outside the de-icing ring 41 and the driven gear 33, and a drive housing is located below the annular shell. The bottom of the drive housing can be mounted on other machinery, making the application scenarios of the de-icing device more extensive. The specific position of the drive component 2 in the de-icing device is also not limited. In a preferred embodiment, the drive component 2 is located below the de-icing ring 41. This arrangement saves space occupied by the de-icing component 4, thus making the entire de-icing device structure more compact. The specific connection method of the drive component 2 within the housing 1 is also not limited; it can be a snap-fit, screw-fit, or other method with the inner arm of the housing 1. The length of the housing 1 and the de-icing ring 41 along the power line is also not limited, as long as it ensures the stability of the de-icing device during the de-icing process on the power line. The de-icing method is not limited. De-icing can be achieved by driving the driven gear 33 to rotate counterclockwise or clockwise through the drive gear on the output end of the drive component 2, or by switching the rotation direction of the drive component 2 to make the driven gear 33 rotate back and forth, thereby achieving the de-icing effect.
[0034] In a preferred embodiment, the drive assembly 2 includes a first drive motor 21 and a second drive motor 22, and the drive gears include a first drive gear 31 and a second drive gear 32. The first drive gear 31 is connected to the output end of the first drive motor 21, and the second drive gear 32 is connected to the second drive motor 22. This arrangement uses two drive motors to drive the first drive gear 31 and the second drive gear 32 respectively, ensuring sufficient power for the rotation of the driven gear 33, improving de-icing efficiency, and preventing situations such as jamming of the de-icing device due to insufficient power. The specific arrangement of the first drive motor 21 and the second drive motor 22 is not limited here; they can be arranged side-by-side or staggered, as long as the first drive gear 31 and the second drive gear 32 mesh with the driven gear 33.
[0035] It should be noted that the distance between the first drive motor 21 and the second drive motor 22 is not limited here. In a preferred embodiment, the distance between the first drive motor 21 and the second drive motor 22 satisfies the condition that the distance between the first drive gear 31 and the second drive gear 32 is greater than the width of the second opening 33a. This arrangement ensures that at least one drive gear remains engaged with the driven gear 33 at all times, thereby making the entire transmission system more reliable and stable and preventing transmission disconnection. Preferably, the first drive motor 21 and the second drive motor 22 are encoder motors, ensuring that the rotational speeds of the first drive gear 31 and the second drive gear 32 are consistent, thus ensuring the effective driving of the driven gear 33.
[0036] In a preferred embodiment, the de-icing assembly 4 further includes a protective ring 43, which is disposed inside the de-icing ring 41. The thickness of the protective ring 43 is equal to the height of the de-icing blade 42. This arrangement ensures that the de-icing blade 42 can cut away ice from the power transmission line without contacting it, thus protecting the power transmission line. It also further reduces the resistance encountered by the de-icing ring 41 during rotation, improving de-icing efficiency.
[0037] The specific position and arrangement of the protective ring 43 inside the de-icing ring 41 are not limited here. Optionally, one protective ring 43 can be provided inside the de-icing ring 41, with the protective ring 43 located in the middle of the de-icing ring 41; alternatively, multiple protective rings 43 can be provided inside the de-icing ring 41, with the multiple protective rings 43 evenly distributed inside the de-icing ring 41. Preferably, one or more protective rings 43 are arranged perpendicular to the axis of the de-icing ring 41, that is, the protective ring 43 is perpendicular to the transmission line. This arrangement can improve the protective effect of the protective ring on the transmission line. In a preferred case, the inner diameter of the protective ring 43 is greater than or equal to the diameter of the transmission line. This arrangement ensures that the transmission line is not damaged during the de-icing process, and at the same time ensures that the de-icing device can be smoothly installed on the transmission line and successfully complete the de-icing work.
[0038] In a preferred embodiment, the de-icing blade 42 is inclined inside the de-icing ring 41, and the inclination angle of the de-icing blade 42 matches the winding direction of the power transmission line. This arrangement allows the de-icing blade 42 to operate more smoothly during the de-icing process, improving de-icing efficiency and reducing damage to the power transmission line.
[0039] In a preferred embodiment, there are multiple de-icing blades 42, evenly distributed inside the de-icing ring 41. The specific number of de-icing blades 42 is not limited here. When there are two de-icing blades 42, they are positioned symmetrically on the inner wall of the de-icing ring 41, and the distance between the third openings 41a of the two blades is equal. With this arrangement, the symmetrically arranged de-icing blades 42 ensure balanced resistance during rotation, resulting in more stable rotation. When there are two or more de-icing blades 42, they are evenly distributed on the inner wall of the de-icing ring 41. This arrangement allows multiple de-icing blades 42 to simultaneously remove ice from the power line, improving the de-icing effect.
[0040] In a preferred embodiment, the transmission line de-icing device further includes a bearing assembly disposed between the de-icing ring 41 and the housing 1. The bearing assembly allows the de-icing ring 41 to rotate smoothly relative to the housing 1, thereby ensuring the stability and reliability of the de-icing device during operation. Furthermore, the bearing assembly can withstand certain radial and axial loads, thus preventing the driven gear 33 from bearing loads during rotation and further improving the structural strength of the entire device. It should be noted that the number and position of the bearing assemblies are not limited here. A single bearing can be placed in the middle of the de-icing ring 41 to ensure stable rotation of the de-icing ring 41 relative to the housing 1; alternatively, bearings can be placed at both ends of the de-icing ring 41 to further improve the connection between the de-icing ring 41 and the housing 1, reduce energy loss during the rotation of the de-icing ring 41, and thus improve de-icing efficiency.
[0041] Another aspect of this utility model provides a power transmission line inspection robot, including the aforementioned power transmission line de-icing device.
[0042] The connection method between the de-icing device and the power line inspection robot is not limited here; the de-icing device can be snapped onto the power line inspection robot as a whole, or screwed onto it. In a preferred embodiment, the housing 1 of the de-icing device is configured as an annular outer shell and a drive housing located below the annular outer shell, with the power line inspection robot connected to the drive housing. The connection method between the power line inspection robot and the drive housing is not limited here; it can be screwed or snapped onto, etc.
