Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically to an anti-static high-voltage cable tray. Background Technology
[0002] High-voltage cable trays are rigid structural devices used to support and lay high-voltage cables. They are mainly used in high-voltage power systems such as substations, large industrial plants, and high-rise buildings. They form continuous channels through components such as brackets and supports to fix high-voltage cables in an orderly manner, avoiding the cables from being suspended and subjected to stress or being piled up haphazardly. At the same time, they play a protective role, reducing the impact of external mechanical damage and environmental corrosion on the cables. Among them, the horizontal four-way trough-type cable tray is an important branch component. It has a trough-shaped closed structure and can realize the cross-diversion of four cables in the horizontal direction. However, in actual use, the cables above the junction of the four-way trough-type cable trays inevitably come into contact with the high-voltage cables below. Especially when the high-voltage cables are pulled during installation and adjustment, friction is increased and static electricity is generated. Although the existing solutions use partitions for physical isolation, the partitions still rub against the cables placed above them, and the partitions cannot completely eliminate static electricity. The accumulation and conduction of static electricity generated by the high-voltage cables can easily pose a potential risk to the equipment. Therefore, an anti-static high-voltage cable tray is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-6 This utility model provides a technical solution: An anti-static high-voltage cable tray includes a horizontal four-way slotted cable tray body 1. A load-bearing adjustment assembly 2 is installed inside the horizontal four-way slotted cable tray body 1, and an electrostatic elimination conductive component 3 is installed above the load-bearing adjustment assembly 2. The load-bearing adjustment assembly 2 includes a main load-bearing plate 21, with sliding guide rails 22 fixed on both sides of the main load-bearing plate 21. A secondary load-bearing plate 23 is slidably connected to the outer side of the sliding guide rails 22. Fixing holes are provided on the surface of both the main load-bearing plate 21 and the secondary load-bearing plate 23. Connecting seats 24 are fixed at the two corners on the outer side of the secondary load-bearing plate 23. Both ends of the inner side of the seat 24 are fixed with buffer dampers 25; the static elimination conductive component 3 includes a spherical connector 31, the top of the spherical connector 31 is connected to a height adjustment screw 32, the top of the height adjustment screw 32 is connected to a wire fixing seat 33, one side of the wire fixing seat 33 is provided with a wire insertion hole 34 for connecting a grounding wire, the inner side of the wire insertion hole 34 is fixed with left and right symmetrical elastic clamping pieces 35, and the outer wall of the wire fixing seat 33 is screwed with a fastening knob 36; the spherical connector 31 is slidably connected to the inside of the connector 24.
[0017] As a further implementation of this solution, the connector 24 is arranged in an "L" shape, and the spherical connector 31 is located between the telescopic ends of the two corresponding buffer dampers 25. The spherical connector 31 has a spherical structure. When the spherical connector 31 contacts the telescopic end of the corresponding buffer damper 25, the elastic buffering performance of the buffer damper 25 is used to offset or reduce the impact force caused by the movement of the sub-bearing plate 23, thereby maximizing the elimination of mutual interference between the left and right adjacent cables. As a further implementation of this solution, the bottom of the main bearing plate 21 and the bottom of the secondary bearing plate 23 are located on the same horizontal plane. The length of the main bearing plate 21 is 1.2 times the length of the secondary bearing plate 23. The length makes it easy to distinguish them. The two secondary bearing plates 23 are symmetrically arranged with the main bearing plate 21 as the center. There is a gap between the secondary bearing plate 23 and the horizontal four-way channel cable tray body 1. This arrangement facilitates heat dissipation and avoids heat accumulation that may affect cable performance and anti-static effect. As a further implementation of this solution, the height adjustment screw 32 extends above the horizontal four-way cable tray body 1. The top of the horizontal four-way cable tray body 1 has an arc-shaped structure. An anti-static support seat 5 is fixed to the top of the horizontal four-way cable tray body 1. The position of the anti-static support seat 5 corresponds to the position of the height adjustment screw 32. The anti-static support seat 5 is spirally connected to the height adjustment screw 32. This arrangement allows for flexible adjustment of the distance between the high-voltage cables on the main bearing plate 21 and the secondary bearing plate 23 and the cables below. As a further implementation of this solution, the vertical projection shape of the horizontal four-way cable tray body 1 is cross-shaped, and the four corner areas of the top inner side of the horizontal four-way cable tray body 1 are all provided with flat grooves 4 to reduce the risk of accidental scratches to operators and cables. As a further implementation of this scheme, the center of the conductor fixing seat 33 and the center of the height adjusting screw 32 are located on the same central axis, and the two elastic clamping pieces 35 have an arc-shaped structure on the corresponding side, which can clamp the grounding conductor and form a preliminary limit. As a further implementation of this solution, the center of the fastening knob 36 and the center of the wire fixing seat 33 are located on the same central axis. The fastening knob 36 is located outside the elastic clamping piece 35. The outer wall of the fastening knob 36 is provided with an anti-slip groove. The upward movement of the fastening knob 36 can further squeeze and limit the wire to ensure that the grounding wire is firmly connected.
[0018] Workflow: The load-bearing adjustment component 2 is installed inside the horizontal four-way cable tray body 1. The main load-bearing plate 21 and the secondary load-bearing plate 23 are slidably connected by the sliding guide rail 22. According to the actual high-voltage cable layout requirements, the relative positions of the main load-bearing plate 21 and the secondary load-bearing plate 23 are adjusted so that they are in a suitable load-bearing position. Since the main load-bearing plate 21 and the secondary load-bearing plate 23 are located on the same horizontal plane and are symmetrically arranged with the main load-bearing plate 21 as the center, the balance of cable placement can be guaranteed. A high-voltage cable is placed on each of the main load-bearing plate 21 and the secondary load-bearing plate 23. Using the fixing holes opened on the surface of the main load-bearing plate 21 and the secondary load-bearing plate 23, limiters are installed to limit the cables, reduce the shaking of the cables during use, and reduce the probability of static electricity generated by shaking friction. Meanwhile, because the main support plate 21 and the secondary support plate 23 have different lengths, the cables they carry can be easily distinguished. The height of the support adjustment assembly 2 can be adjusted by rotating the height adjustment screw 32 according to the required distance between the upper and lower cables. Since the height adjustment screw 32 is screwed to the anti-static support seat 5 at the top of the horizontal four-way cable tray body 1, rotating the height adjustment screw 32 can drive the entire support adjustment assembly 2 to rise or fall, thereby adjusting the distance between the high-voltage cables on the main support plate 21 and the secondary support plate 23 and the cables below, preventing high-voltage cables from moving between upper and lower layers. Static electricity is generated by the contact friction of the cable. The external grounding wire is inserted through the wire insertion hole 34 on one side of the wire fixing seat 33. The elastic clamping pieces 35 on the inner side of the wire insertion hole 34, which are symmetrical on the left and right, will clamp the wire and form an initial limit. Then, the fastening knob 36 is rotated. Since the fastening knob 36 is spirally connected to the outer wall of the wire fixing seat 33, the upward movement of the fastening knob 36 can further squeeze and limit the wire, ensuring that the grounding wire is firmly connected. At this time, the static electricity generated on the surface of the load adjustment component 2 can be conducted to the grounding wire through the static electricity elimination conductor 3, thereby eliminating the static electricity. During daily use, when the cables on the main bearing plate 21 and the secondary bearing plate 23 move slightly due to external factors, the sliding connection between the main bearing plate 21 and the secondary bearing plate 23 provides a certain buffer space for movement. If the secondary bearing plate 23 moves, the spherical connector 31 will interact with the telescopic end of the buffer damper 25 in the direction of movement. The elastic buffering performance of the buffer damper 25 will be used to offset or weaken the impact force caused by the movement, thereby maximizing the elimination of mutual interference between adjacent cables on the left and right sides and further reducing the static electricity generated by the collision and friction between the cables.
