Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a cable tray with a fireproof partition. Background Technology

[0002] In modern buildings and industrial facilities, cable trays are an important cable laying device, widely used in the laying of cables for power, communication, and control systems. They not only organize and support cables in an orderly manner, but also provide a certain degree of protection against external factors such as mechanical damage and chemical corrosion.

[0003] However, with increasing societal emphasis on fire safety, the shortcomings of traditional cable trays in fire protection have become increasingly apparent. In the event of a fire, traditional cable trays lack effective fire-resistant insulation measures, allowing flames and high temperatures to spread rapidly along the cables, leading to widespread fire damage and serious property loss and casualties. For example, in large shopping malls and factories, where cable trays run through various areas, flames can quickly spread throughout the building in the event of a fire, greatly hindering firefighting efforts. Therefore, this application proposes a cable tray with a fire-resistant partition. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] This embodiment provides a cable tray with a fireproof partition, the structural diagram of which is shown below. Figures 1-4 As shown, it includes a cable tray 1, a cover plate 2, and a hoisting structure.

[0026] In this embodiment, the cable tray 1 is a groove-shaped structure with an open top, used to place cables. The cover plate 2 is detachably mounted on the top of the cable tray 1. Specifically, the side of the cover plate 2 facing inward into the cable tray 1 is embedded in the cable tray 1, the two sides of the cover plate 2 are bent downward to fit against the outer side of the cable tray 1, and the two sides of the cover plate 2 are connected and fixed to the side of the cable tray 1 by screws, ensuring that the cover plate 2 and the cable tray 1 are tightly assembled, preventing dust, debris, etc. from entering the interior of the cable tray 1, and also providing a certain degree of protection.

[0027] In this embodiment, fire-resistant interlayers 7 are provided inside the side walls, bottom wall of the wire duct 1, and inside the cover plate 2. The fire-resistant interlayers 7 are filled with a flame-retardant gas, such as carbon dioxide. Through holes 16 are formed on one side of the cover plate 2 facing the inside of the wire duct 1, and on the inner side walls and bottom wall of the wire duct 1. The through holes 16 communicate with the fire-resistant interlayers 7, and a thin film is provided in the through holes 16. The thin film will quickly melt when encountering an open flame or when the temperature is higher than 60 degrees Celsius. When a fire occurs, the high temperature or open flame will cause the thin film to melt, and the flame-retardant gas in the fire-resistant interlayers 7 will be released into the inside of the wire duct 1 through the through holes 16, playing a role in isolating oxygen and suppressing the spread of fire.

[0028] In this embodiment, inflation nozzles 6 are further provided on one side of the cover plate 2 facing the outside of the wire duct 1, and on the outer side walls and bottom wall of the wire duct 1. The inflation nozzles 6 are connected to the fire-resistant interlayers 7. The inflation nozzles 6 adopt a one-way valve structure for one-way inflation towards the fire-resistant interlayers 7, facilitating the replenishment when the flame-retardant gas in the fire-resistant interlayers 7 is insufficient.

[0029] Furthermore, in this embodiment, a fireproof coating is applied on one side of the cover plate 2 facing the outside of the wire duct 1 and on the outer surface of the wire duct 1, further enhancing the fireproof performance of the cable tray. At the same time, a flame-retardant padding 8 is provided on the inner wall of the fire-resistant interlayers 7. The flame-retardant padding 8 can better prevent the spread of fire in the fire-resistant interlayers 7 and improve the fireproof effect.

[0030] As a preferred technical solution in this embodiment, a hoisting structure is used for hoisting the cable tray. The hoisting structure includes a boom 3 horizontally arranged at the bottom of the wire duct 1, and the boom 3 is distributed along the width direction of the wire duct 1. Both sides of the boom 3 are vertically bent downward, and guide grooves 12 are formed at both ends of the boom 3, and the guide grooves 12 are distributed along the length direction of the boom 3. A pair of fastening blocks 10 are provided on the boom 3, and convex ribs 5 are provided at the bottom of both sides of the wire duct 1. The bottom of the fastening block 10 is connected with a slider 13. The slider 13 is set in a "convex" shape. The top of the slider 13 is slidably fitted with the guide groove 12, and the bottom of the slider 13 is located below the boom 3 and is in contact with the lower surface of the boom 3, so that the fastening block 10 can slide along the guide groove 12 on the boom 3. A convex block 15 is provided at the top of the fastening block 10 facing one side of the wire duct 1, and a tightening structure is further provided at the end of the boom 3. The tightening structure includes a bolt 11 horizontally threaded through a fixing block 9. The fixing block 9 is fixed at both ends of the top of the boom 3, and the bolt 11 is rotatably connected with the fastening block 10. A self-locking hexagonal end cap 14 is provided at one end of the bolt 11 away from the fastening block 10.

[0031] Furthermore, a hanger 4 is fixed on the fixing block 9. The hanger 4 is used to connect the boom 3 and the ceiling and other supporting structures. When it is necessary to install the cable tray, the hanger 4 is first fixed on the ceiling, and then the cable tray 1 is placed on the boom 3. By sliding the fastening block 10, the protrusion 15 on the fastening block 10 is brought close to the protruding edge 5 at the bottom of the cable tray 1. The self-locking hexagonal end cap 14 is turned, which drives the bolt 11 to rotate and pushes the fastening block 10 toward the cable tray 1, so that the protrusion 15 and the protruding edge 5 are engaged. At the same time, the self-locking hexagonal end cap 14 is pressed against the fixing block 9 and locked, thereby firmly fixing the cable tray 1 to the boom 3.

[0032] Working principle:

[0033] Under normal circumstances, the flame-retardant gas within the flame-retardant interlayer 7 is sealed within the interlayer by a thin film. In the event of a fire, if the temperature inside or around the cable tray 1 rises above 60 degrees Celsius or if it encounters an open flame, the thin film within the through-hole 16 will rapidly melt, releasing the flame-retardant gas within the flame-retardant interlayer 7 into the cable tray 1 through the through-hole 16. The flame-retardant gas isolates oxygen and inhibits flame combustion. Simultaneously, the fire-retardant coating and flame-retardant padding 8 also prevent flame propagation, thus protecting the cables within the cable tray 1 from fire damage.

[0034] The boom 3 is fixed to the ceiling by the hanger rod 4. The fastening block 10 is fastened to the protruding edge 5 at the bottom of the cable tray 1. The fastening block 10 is tightly connected to the cable tray 1 by the cooperation of the bolt 11 and the self-locking hexagonal end cap 14, so that the cable tray 1 can be hoisted and fixed.

[0035] All technical features in this embodiment can be freely combined according to actual needs.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
