A booster station transmission line cleaning device

Abstract

This application discloses a cleaning device for power transmission lines in a substation, belonging to the technical field of power transmission lines in substations. It mainly includes a support rod, a guide assembly movably mounted on one side of the outer wall of an L-shaped plate, and a cleaning assembly embedded in the inner cavity of the guide assembly. By activating a second electric telescopic rod, a sliding U-shaped block is moved, causing brushes at the upper and lower ends of the built-in concave inner wall installed in the inner cavity of the sliding U-shaped block to clean impurities from the surface of the power transmission line. When the brushes become dirty, pulling a pulling rod moves a connecting block, which in turn moves an insertion block and a first triangular block. This movement causes a spring to contract, shifting the position of the insertion block and the first triangular block. The first triangular block loses its pressure on the second triangular block, causing the locking block and the second triangular block to disengage from the inner cavity of the insertion slot. This allows for timely replacement of the built-in concave inner wall and the brushes, making it convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of power transmission line technology for substations, specifically a cleaning device for power transmission lines in substations. Background Technology

[0002] Because the transmission lines of the substation are exposed to the outdoors for a long time, dust, oil, moisture and other pollutants will accumulate on their surface. Under humid conditions, these pollutants may cause a decline in insulation performance, leading to phase-to-phase creepage or short circuit accidents. At the same time, freezing may occur on the transmission lines in winter. Ice accumulation increases the weight of the conductors and the wind resistance area, which may lead to conductor breakage or tower collapse. Therefore, regular cleaning with cleaning equipment can effectively reduce safety hazards.

[0003] For example, patent CN220273164U discloses a maintenance structure for high-voltage transmission lines. It includes a support rod, handle, adjusting rod, cleaning mechanism, vibration assembly, auxiliary cleaning assembly, and the support rod allows for easy height adjustment of the adjusting rod according to the height of the high-voltage transmission line. The cleaning mechanism facilitates the removal of frost adhering to the surface of the high-voltage transmission line.

[0004] In use, the aforementioned maintenance structure for high-voltage transmission lines uses a telescopic cylinder to drive a slider upwards, causing the insulating block at the upper end of the slider to vibrate against the frost on the transmission line surface. Then, by activating a transverse cylinder, the sliding U-shaped block and the cleaning brushes on the upper and lower sides of the inner wall of the sliding U-shaped block are used to clean impurities on the outer surface of the transmission line. However, since the sliding U-shaped block is fixedly installed on one side of the outer wall of the L-shaped plate, it is impossible to replace the brushes on the upper and lower sides of the inner wall of the sliding U-shaped block in a timely manner when they become dirty or damaged, making it inconvenient to use.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0027] like Figure 1 As shown, a substation transmission line cleaning device includes a support rod 1 and a threaded extension rod 2 threadedly connected to the upper end of the support rod 1. The threaded extension rod 2 is threaded into the inner cavity of the support rod 1 to adjust the overall length of the support rod 1. An L-shaped plate 3 is fixedly installed at the upper end of the threaded extension rod 2. A first electric telescopic column 4 is fixedly installed at the middle of the upper end of the L-shaped plate 3. A slider 5 is fixedly installed at the upper end of the first electric telescopic column 4. Multiple sets of insulating layers are linearly and equally spaced at the upper end of the slider 5. An auxiliary cleaning block is fixedly installed at the upper end of one side of the inner wall of the L-shaped plate 3. 6. The first electric telescopic column 4 is set to drive the slider 5 to move up and down in conjunction with the auxiliary cleaning block 6 to vibrate the frost on the surface of the transmission line. A guide component 7 is installed on one side of the outer wall of the L-shaped plate 3. The cleaning component 8 is embedded in the inner cavity of the guide component 7. The guide component 7 can drive the cleaning component 8 to move in a guiding manner, so that the cleaning component 8 can clean the dirt on the surface of the transmission line harness. A drive component 9 is fixedly installed in the middle of one side of the outer wall of the L-shaped plate 3. The drive component 9 is set to drive the guide component 7 to move in position.

[0028] The guide assembly 7 includes a support mechanism 71 and a rebound mechanism 72 that is movably mounted on one side of the outer wall of the support mechanism 71. The support mechanism 71 is configured to support the installation of the cleaning assembly 8, and the rebound mechanism 72 is configured to limit and fix the installation of the cleaning assembly 8.

[0029] like Figure 5 As shown, the support mechanism 71 includes a sliding U-shaped block 711 and an insertion groove 712 linearly and equally spaced at the middle of one end of the inner wall of the sliding U-shaped block 711. A semi-embedded groove 713 is provided in the middle of one side of the inner wall of the insertion groove 712. The depth of the semi-embedded groove 713 is half of the inner wall of the insertion groove 712 and does not completely penetrate the inner wall of the insertion groove 712. A through circular groove 714 is provided in the middle of the inner wall of the insertion groove 713. A cross-shaped slot 715 is provided in the middle of the upper and lower sides of the inner wall of the sliding U-shaped block 711. The cross-shaped slot 715 is provided to limit the installation of the cleaning component 8 installed in the inner cavity of the sliding U-shaped block 711. A guide block 716 is fixedly installed in the middle of one side of the outer wall of the sliding U-shaped block 711. The guide block 716 is used to limit the sliding position of the sliding U-shaped block 711 when it slides.

[0030] like Figure 4 As shown, the rebound mechanism 72 includes a connecting block 721 and a pull rod 722 fixedly installed on one side of the connecting block 721. The pull rod 722 drives the connecting block 721 to move its position. On the other side of the connecting block 721, a plurality of insertion rods 723 are fixedly installed at equal intervals. The insertion rods 723 are movably installed in the inner cavity of the through circular groove 714. One end of the insertion rod 723 is fixedly installed with an insertion block 724. The insertion block 724 is movably installed in the inner cavity of the semi-embedded groove 713. At the same time, one end of the spring 726 is limited by one end of the insertion block 724. The other end of the spring 726 is larger than the set diameter of the through circular groove 714 and is movably installed in the inner cavity of the through circular groove 714. One end of the insertion block 724 is fixedly installed with a first triangular block 725. The outer surface of the insertion rod 723 is movably sleeved with the spring 726.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the cleaning component 8 includes a built-in concave shape 81 and brushes 82 implanted at the upper and lower ends of the inner wall of the built-in concave shape 81. The built-in concave shape 81 is movably installed in the inner cavity of the sliding U-shaped block 711. The brushes 82 are designed to clean impurities in the power transmission line. The brushes 82 can be replaced by replacing the built-in concave shape 81. Cross-shaped locking blocks 83 are fixedly installed at the middle of the upper and lower ends of the outer wall of the built-in concave shape 81. The cross-shaped locking blocks 83 are limited and movablely embedded in the inner cavity of the cross-shaped locking groove 715, thereby improving the stability of the built-in concave shape 81 installed in the inner cavity of the sliding U-shaped block 711.

[0032] like Figure 4 As shown, multiple locking blocks 811 are fixedly installed linearly and at equal intervals on one side of the outer wall of the built-in concave 81. The locking blocks 811 are movably installed in the inner cavity of the insertion slot 712. A second triangular block 812 is fixedly installed on one side of the outer wall of the locking block 811. The second triangular block 812 and the first triangular block 725 are locked together for limiting.

[0033] In this application, the operator uses a handheld support rod 1 and threaded extension rod 2 to raise the concave block composed of the L-shaped plate 3 and the auxiliary cleaning block 6, allowing the transmission line to enter the inner cavity of the L-shaped plate 3 and the auxiliary cleaning block 6. Activating the first electric telescopic column 4 moves the slider 5 up and down in coordination with the auxiliary cleaning block 6, vibrating the frost on the surface of the transmission line. Activating the second electric telescopic rod 94 pushes the sliding U-shaped block 711 to move, causing the brushes 82 at the upper and lower ends of the inner wall of the built-in concave shape 81 installed in the inner cavity of the sliding U-shaped block 711 to clean impurities from the surface of the transmission line. When the brushes 82 become dirty... If damaged, the connecting block 721 can be moved by pulling the lever 722. When the connecting block 721 moves, it will move the insertion block 724 and the first triangular block 725. When the insertion block 724 and the first triangular block 725 move, the spring 726 will contract, thereby moving the insertion block 724 and the first triangular block 725. This will cause the first triangular block 725 to lose its pressure on the second triangular block 812, so that the locking block 811 and the second triangular block 812 can be removed from the inner cavity of the insertion slot 712. This allows for timely replacement of the built-in concave 81 and the brush 82, making it convenient to use.

[0034] like Figure 6 As shown, the drive assembly 9 includes a concave fixing block 91 and a limiting groove 92 formed in the middle of one side of the inner wall of the concave fixing block 91. One end of the concave fixing block 91 is fixedly installed in the middle of one side of the outer wall of the L-shaped plate 3, and the other end of the concave fixing block 91 is movably disposed with the sliding U-shaped block 711. The guide block 716 is slidably installed in the inner cavity of the concave fixing block 91 and the limiting groove 92. A corresponding sealing plate 93 is fixedly installed at one end of the concave fixing block 91. The corresponding sealing plate 93 is set to limit the sliding position of the guide block 716. A second electric telescopic rod 94 is fixedly installed at one end of the inner cavity of the concave fixing block 91. One end of the second electric telescopic rod 94 is fixedly installed with one end of the guide block 716, and at the same time drives the guide block 716 to move.

[0035] In this application, when the second electric telescopic rod 94 drives the sliding U-shaped block 711 to move, the guide block 716, which is fixedly installed on one side of the outer wall of the sliding U-shaped block 711, slides along the concave fixed block 91 and the limiting groove 92, thereby improving the stability of the sliding U-shaped block 711 during cleaning.

[0036] In summary: Through the coordinated use of the second electric telescopic rod 94, the sliding U-shaped block 711, the built-in concave shape 81, the brush 82, the pull rod 722, the connecting block 721, the insertion block 724, the first triangular block 725, the spring 726, the insertion block 724, the second triangular block 812, and the second triangular block 812, the insertion block 724 and the first triangular block 725 are moved, causing the first triangular block 725 to lose its pressure on the second triangular block 812, thereby enabling... The locking block 811 and the second triangular block 812 are withdrawn from the inner cavity of the insertion slot 712, and the built-in concave 81 and brush 82 are replaced in time. Through the coordinated use of the second electric telescopic rod 94, the sliding U-shaped block 711, the guide block 716, the concave fixing block 91 and the limiting groove 92, the guide block 716, which is fixedly installed on one side of the outer wall of the sliding U-shaped block 711, will slide along the concave fixing block 91 and the limiting groove 92, thereby improving the stability of the sliding cleaning of the sliding U-shaped block 711.

[0037] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
