Description

Technical Field

[0001] This utility model relates to the technical field of cable trays, and in particular to a trapezoidal cable tray. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays can be installed independently within buildings or laid on various building and pipe rack supports. Ladder type cable trays offer advantages such as simple structure and good heat dissipation during use.

[0003] When using trapezoidal cable trays to support cables, although their open structure optimizes cable heat dissipation, suspended impurities such as dust, lint, and fibers in the air easily accumulate on the cable surface and in the gaps between the tray's cross braces. Dust particles continuously rub against the insulation layer, causing gradual wear and reducing the cable's insulation performance, thus affecting its service life and operational stability. Furthermore, if high-voltage and low-voltage cables are mixed in the same trapezoidal cable tray without separation, the electromagnetic radiation generated by the high-voltage cables can interfere with the transmission of low-voltage signals. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to propose a trapezoidal cable tray that can be divided into multiple spaces by adding partitions, thereby preventing electromagnetic radiation from high-voltage cables from interfering with the transmission of low-voltage signals. Furthermore, dustproof and waterproof effects can be achieved by setting dustproof nets and changing the shape of the cover plate.

[0006] To achieve the above objectives, the first aspect of this utility model provides a trapezoidal cable tray, comprising: a trapezoidal cable tray, wherein the trapezoidal cable tray includes two side plates, multiple connecting columns, multiple locking blocks, multiple partitions, a cover plate, a first bolt, a dustproof net, and multiple second bolts, wherein the two ends of the multiple connecting columns are respectively connected to the side walls of the two side plates; the multiple locking blocks are respectively disposed on the multiple connecting columns; the multiple partitions are respectively locked and connected to the corresponding locking blocks; the cover plate is disposed on the two side plates; the first bolt passes through the cover plate and is threadedly connected to the corresponding side plate; the dustproof net is disposed on the bottom wall of the two side plates; and the multiple second bolts pass through the dustproof net and are threadedly connected to the bottom wall of the corresponding side plate.

[0007] In addition, the trapezoidal cable tray proposed above according to this utility model may also have the following additional technical features: Specifically, limit grooves are equidistantly provided on the upper walls of multiple connecting columns.

[0008] Specifically, the side walls of the two side plates are respectively provided with connecting components. Each connecting component includes a connecting plate and four third bolts. The side walls of the side plates are symmetrically provided with mounting grooves. The connecting plates are installed in the corresponding mounting grooves. The four third bolts pass through the connecting plates and are threaded to the corresponding side plates.

[0009] Specifically, two rubber pads are symmetrically arranged on the bottom wall of the cover plate.

[0010] Specifically, protective pads are provided in each of the multiple limiting grooves.

[0011] Compared with the prior art, the present invention has the following advantages: a cover plate with a flow guiding function can be installed on the upper part of the trapezoidal cable tray. When water falls on the trapezoidal cable tray, it can slide off through the cover plate, thereby preventing water from entering the interior of the trapezoidal cable tray. Then, the trapezoidal cable tray can be divided into multiple spaces by partitions, thereby preventing electromagnetic radiation generated by high-voltage cables from interfering with the transmission of low-voltage signals.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0015] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0016] The trapezoidal cable tray of this utility model is described below with reference to the accompanying drawings.

[0017] like Figure 1 - Figure 3 As shown, the trapezoidal cable tray of this utility model embodiment includes: trapezoidal cable tray 1.

[0018] The trapezoidal cable tray 1 includes two side plates 11, multiple connecting columns 12, multiple clamping blocks 13, multiple partitions 14, a cover plate 16, a first bolt 17, a dustproof net 18, and multiple second bolts 19.

[0019] Among them, the two ends of multiple connecting columns 12 are respectively connected to the side walls of two side plates 11, multiple locking blocks 13 are respectively set on multiple connecting columns 12, multiple partitions 14 are respectively engaged with the corresponding locking blocks 13, cover plates 16 are set on two side plates 11, first bolts 17 pass through cover plates 16 and are threadedly connected to the corresponding side plates 11, dustproof nets 18 are set on the bottom walls of two side plates 11, and multiple second bolts 19 pass through dustproof nets 18 and are threadedly connected to the bottom walls of the corresponding side plates 11.

[0020] It should be noted that the side plate 11 described in this embodiment should be made of a metal shielding material to avoid electromagnetic radiation from the high-voltage cable interfering with the transmission of low-voltage signals.

[0021] It should be noted that the upper wall of the cover plate 16 described in this embodiment is arc-shaped, which allows the water source above to slide down through the cover plate 16 better, and prevents water from accumulating on the cover plate 16.

[0022] Specifically, when it is necessary to store and support cables, the staff can install the side plate 11 and the connecting column 12 in the required fixed position through the connecting frame. Then, the staff can snap the appropriate amount of partition 14 into the card block 13 according to the number of cables to be stored and supported and the condition of the cables, thereby dividing the trapezoidal cable tray 1 into suitable spaces. Then, different types of cables are separated into different spaces to prevent the electromagnetic radiation generated by high-voltage cables from interfering with the transmission of low-voltage signals.

[0023] Next, the workers can place the cover plate 16 on top of the two side plates 11, and then rotate the first bolt 17 through the cover plate 16 and thread it onto the side plate 11, thereby fixing the cover plate 16 on top of the side plate 11. At this time, when rainwater or condensation falls on the cover plate 16, the water can slide off through the cover plate 16 better, and there will be no water accumulation on the cover plate 16, thus achieving a certain waterproof effect. Then, the workers can place the dustproof net 18 on the bottom wall of the side plate 11, and then rotate the second bolt 19 through the dustproof net 18 and thread it onto the side plate 11, thereby preventing dust and powder particles from entering the interior of the trapezoidal cable tray 1, causing friction on the cable, and thus affecting the service life of the cable.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, limit grooves 15 are equidistantly provided on the upper walls of multiple connecting columns 12.

[0025] It is understandable that by using the equidistant limiting grooves 15 opened on the upper wall of the connecting column 12, workers can install cables in the limiting grooves 15, thereby limiting the position of the cables to a certain extent.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, the side walls of the two side plates 11 are respectively provided with connecting components 3.

[0027] Each set of connecting components 3 includes a connecting plate 32 and four third bolts 33. The side wall of the side plate 11 is symmetrically provided with mounting grooves 31. The connecting plate 32 is installed in the corresponding mounting groove 31. The four third bolts 33 pass through the connecting plate 32 and are threadedly connected to the corresponding side plate 11.

[0028] Specifically, when it is necessary to splice two or more trapezoidal cable trays 1 together for use, the worker can splice two trapezoidal cable trays 1 together, then install the connecting plate 32 into the mounting groove 31 opened on the side plate 11 on the same side of the two trapezoidal cable trays 1, then rotate the third bolt 33 one by one to pass through the connecting plate 32 and connect it to the side plate 11, and then install another connecting plate 32 into another mounting groove 31 in the same way, thereby splicing two or more trapezoidal cable trays 1 together for use.

[0029] In one embodiment of this utility model, such as Figure 2 As shown, two rubber pads 2 are symmetrically arranged on the bottom wall of the cover plate 16.

[0030] It is understandable that by symmetrically setting two rubber pads 2 on the bottom wall of the cover plate 16, the connection point between the cover plate 16 and the side plate 11 can be sealed, thereby better preventing water from entering the interior of the trapezoidal cable tray 1 through the connection point between the side plate 11 and the cover plate 14 and damaging the cables inside the trapezoidal cable tray 1.

[0031] In one embodiment of this utility model, such as Figure 3 As shown, each of the multiple limiting grooves 15 is provided with a protective pad 4.

[0032] It is understandable that by setting protective pads 4 in the multiple limiting grooves 15, the friction between the inner wall of the limiting groove 15 and the cable is increased, thereby preventing the cable from rubbing against the inside of the limiting groove 15 and thus damaging the cable.

[0033] In summary, a cover plate with a flow guiding function can be installed on the upper part of the trapezoidal cable tray. When water falls on the trapezoidal cable tray, it can slide off through the cover plate, thereby preventing water from entering the interior of the trapezoidal cable tray. Then, partitions can be used to divide the trapezoidal cable tray into multiple spaces, thereby preventing electromagnetic radiation generated by high-voltage cables from interfering with the transmission of low-voltage signals.
