Description

Technical Field

[0001] This utility model relates to the field of cable installation technology, and more specifically, to a cable tray. Background Technology

[0002] Cable trays, as a key component in electrical cabling systems, play an irreplaceable role in cable laying in power, communication, and building industries. They not only provide structured channels for cables, enabling the orderly arrangement and positioning of multiple cable groups, but also provide physical protection for the cables through their structure, preventing damage from external mechanical impacts and abrasion. Simultaneously, they guide cables along pre-defined paths, ensuring the safety and ease of maintenance of the cabling system.

[0003] However, in practical applications, the waterproof performance of cable trays remains a key issue limiting their reliability. Since cable trays are typically composed of multiple sections spliced ​​together, tiny gaps inevitably exist at the joints due to factors such as processing precision and installation techniques. In outdoor environments, damp workshops, or underground projects, rainwater, condensation, or other liquids can easily seep into the cable tray's wiring channels through these gaps.

[0004] Liquid intrusion creates a persistently humid environment inside the cable tray, accelerating the aging and deterioration of the cable insulation layer, reducing its insulation performance, and potentially causing corrosion of metal components, thus affecting the overall structural strength of the cable tray. More seriously, a humid environment can cause short circuits at cable joints, signal transmission interference, and other malfunctions, posing a serious threat to the stability of power supply and communication transmission, and may even lead to safety accidents, increasing subsequent maintenance costs and workload. Utility Model Content

[0005] This application provides a cable tray that can effectively drain water and prevent cables from getting damp.

[0006] This application provides a cable tray, comprising: The cable tray body has a wiring groove inside, and through holes are provided at the bottom of both sides of the groove wall; A support beam is provided, with its two ends connected to the two side walls of the wiring trough. There are several support beams, which are arranged horizontally at intervals along the extension direction of the wiring trough to support the cables. A cable tray cover plate, which is movably connected to the top of the cable tray body, is used to open and close the opening of the wiring trough; The horizontal height of the supporting beam is greater than the horizontal height of the through hole.

[0007] Compared with the prior art, the cable tray disclosed in this application has the following advantages: the support beams are higher than the through holes, which can prevent the cables from directly contacting the liquid (such as rainwater) draining from the through holes, preventing the cables from aging or short-circuiting due to moisture, and protecting the insulation performance and signal transmission stability of the cables; the through holes provide a drainage channel for liquid seeping into the wiring trough, reducing liquid accumulation; at the same time, the through holes also facilitate heat dissipation and reduce the temperature of the cables; several horizontally spaced support beams can stably support the cables without obstructing the flow of liquid along the trough wall to the through holes, thus taking into account both support and drainage functions; the movable cover can open and close the opening of the wiring trough, which can protect the cables from external impacts and facilitate wiring and maintenance.

[0008] In one possible implementation, the cable tray body includes a base plate and two side plates, which are integrally connected to both sides of the base plate to form the wiring groove, the wiring groove having a concave cross-section. Compared with the prior art, the concave cross-section of the wiring groove provides a closed channel for cables, facilitating centralized cable arrangement. Simultaneously, the side plates can block external debris from entering, enhancing physical protection for the cables. The integrally molded structure improves the structural strength of the cable tray body, providing stronger impact and deformation resistance, and extending its service life.

[0009] In one possible implementation, the bottom of both side plates is provided with a plurality of through holes, which are spaced apart along the extension direction of the wiring groove. Compared with the prior art, the through holes at the bottom of the side plates are located at a lower position in the wiring groove, which is more conducive to the rapid drainage of liquid and avoids liquid accumulation; the multiple spaced through holes can cover different sections of the wiring groove, ensuring that liquid in all positions in the groove can be effectively drained, improving drainage efficiency and reducing the liquid residence time in the groove.

[0010] In one possible implementation, the support beam has multiple small holes spaced apart along its length. Compared to existing technologies, these holes reduce the weight of the support beam, save materials, and lower production costs; they also facilitate liquid flow, reduce the formation of a humid environment, and delay the aging of the cable insulation layer.

[0011] In one possible implementation, a partition plate is provided on the supporting crossbeam, extending along the length of the cable tray body and located in the middle of the supporting crossbeam. Compared with the prior art, the partition plate can divide the cables on the supporting crossbeam into different areas, avoiding multiple groups of cables from getting tangled and knotted, and realizing classified wiring (such as separation of high-voltage and low-voltage cables); it facilitates quick identification of cables with different functions during later maintenance, improving maintenance efficiency; and it reduces mutual friction and interference between cables, ensuring transmission stability.

[0012] In one possible implementation, the cable tray cover is detachably connected to the cable tray body via bolts. Compared with the prior art, the detachable connection allows the cover to be opened and closed flexibly, facilitating the installation, maintenance, or replacement of cables and solving the problem of difficult operation of fixed covers; the bolt connection is reliable in strength, and when the cover is closed, it can effectively block external dust, debris, or mechanical impact, protecting the cables inside the tray; compared with other movable connection methods, the bolt connection is more suitable for long-term use, is not easily loosened by vibration, and adapts to complex environments.

[0013] In one possible implementation, the cable tray body, supporting beams, and cable tray cover are made of aluminum alloy or steel. Compared with existing technologies, both materials have good processing performance, meeting the requirements of one-piece molding or precision splicing, and ensuring structural reliability.

[0018] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0019] See Figures 1 to 5 This application discloses a cable tray, including: a cable tray body 1, a supporting crossbeam 4, and a cable tray cover plate 5.

[0020] The main body 1 of the cable tray is a long strip structure, and the size of the internal wiring groove 2 can be set according to the actual number of cables. Through holes 3 are provided on both sides of the groove wall, with rounded edges to prevent scratching the cables. The through holes 3 are located near the bottom of the groove to ensure that any seepage can drain smoothly. The size of the through holes 3 is no greater than 10mm to prevent snakes and rats from entering and tearing the cables.

[0021] The support beam 4 is made of the same metal strip as the cable tray body 1, and its length is adapted to the width of the wiring trough 2. Both ends are fixed to the side walls of the trough with bolts. There are several support beams 4, and the spacing between them can be designed according to the weight of the cables. The height of the upper surface of the support beam 4 from the bottom of the trough wall is greater than the horizontal height of the through hole 3. This height difference prevents liquid drained from the through hole 3 from contacting the cables on the support beam 4, thus avoiding moisture damage to the cables.

[0022] The cable tray cover 5 is the same length as the cable tray body 1 and slightly wider than the opening width of the wiring trough 2. It is detachably connected to the top of the cable tray body 1 by bolts. When it is necessary to lay or repair cables, the cover can be opened upwards. During daily use, the cover is closed to prevent dust and rainwater from falling directly into the wiring trough 2. At the same time, the edge of the cover is provided with a downward-facing flange to reduce rainwater infiltration.

[0023] In this embodiment, the cable tray body 1 includes a base plate 11 and two side plates 12, which are integrally connected to both sides of the base plate 11. The three components are connected as a whole through an integral stamping process, forming a concave-shaped wiring groove 2. The base plate 11 has the same length as the overall cable tray; the side plates 12 are perpendicular to the base plate 11. This integral connection structure reduces splicing gaps and improves overall deformation resistance compared to a modular assembly structure.

[0024] In this embodiment, multiple through holes 3 are provided at the bottom of the two side plates 12 along the extension direction of the wiring groove 2. The number of through holes 3 on the same side plate 12 is designed according to the length of the cable tray, and the through holes 3 on the two side plates 12 are symmetrically distributed. The through holes 3 at the bottom can guide the liquid that seeps into the wiring groove 2 to flow down the groove wall and be discharged quickly, avoiding liquid accumulation. At the same time, the symmetrically distributed through holes 3 can balance the drainage speed and improve the drainage speed.

[0025] In this embodiment, the support beam 4 has multiple small holes, which are evenly spaced along its length. These holes penetrate the upper and lower surfaces of the support beam 4, allowing liquid to pass through and reducing liquid accumulation. Furthermore, the holes reduce the weight of the support beam 4, lowering the overall load on the cable tray. They also facilitate the use of cable ties to secure cables.

[0026] In this embodiment, a partition plate 6 is provided on the supporting crossbeam 4. The partition plate 6 is made of metal and is fixed to the middle position of the supporting crossbeam 4 by bolts. The partition plate 6 extends continuously along the length of the cable tray body 1, forming an integral partition structure with each supporting crossbeam 4, dividing the space within the wiring trough 2 into left and right areas. This design can achieve physical separation of high-voltage cables and low-voltage cables, reduce signal interference, and facilitate classified laying and maintenance, avoiding cable tangling and mess.

[0027] In this embodiment, the cable tray body 1, the supporting beam 4, and the cable tray cover plate 5 are made of aluminum alloy plate or steel plate. Both materials have good processing performance and can be flexibly selected according to the humidity, load, and cost budget of the usage environment. The surfaces of the cable tray body 1, the supporting beam 4, and the cable tray cover plate 5 are all provided with an anti-corrosion layer.

[0028] The beneficial effects of this application include: 1. By placing the support beam 4 above the through hole 3, the cable is effectively prevented from coming into contact with the liquid, avoiding moisture, aging or short circuit, and ensuring insulation performance and signal transmission stability.

[0029] 2. Multiple through holes form a drainage structure, which can quickly discharge the seepage liquid, reduce liquid accumulation, improve drainage efficiency, and extend the service life of the cable tray.

[0030] 3. The partition panel 6 separates the strong and weak current cables, avoiding interference and tangling, and facilitating maintenance.

[0031] IV. The cable tray cover plate 5 adopts a detachable connection, which not only protects the cables from external impacts, but also facilitates installation and maintenance.

[0032] V. The overall structure adopts a one-piece molding design, which enhances mechanical strength and resistance to deformation, making it suitable for various complex environments.
