[0028] Please refer to Figures 1-6 , embodiment one:

[0029] Cable tray is a device for managing cables, with types such as arc-shaped and square. However, these cable trays cannot extinguish fire in time when a cable catches fire, leading to the spread of fire and increased losses.

[0030] To solve this problem, a Chinese patent (CN209298793U) proposes a fireproof cable bridge. This bridge is installed with L-shaped embedded slots on both sides of the bottom of the cover plate, and a fire extinguishing belt is embedded in the middle. The fire extinguishing belt is hollow and made of flame-retardant polymer material, and contains fire extinguishing agent inside. In addition, the bridge body has vertical net-shaped partitions that divide the inside into multiple cable clamping slots, and there are ventilation gaps between the clamping slots. The purpose of this design is to protect the cables with the fire extinguishing belt.

For example, the use of net-shaped partitions increases the volume of the cable bridge, and for cases where only a single row of cable is needed, this design is not flexible enough, increasing the cost of use. Based on this, the present application provides a flame-out cable tray suitable for AC and DC cable laying, which includes a closed upper cover 1, the bottom of the upper cover 1 is provided with a lower connecting plate 2, the upper cover 1 and the lower connecting plate 2 are throughly arranged at both ends, for forming a cable tray, limiting the cable connection;

[0032] The plate body of the lower connecting plate 2 is uniformly and evenly provided with one or more sliding grooves 5, and the top of the lower connecting plate 2 is covered with a layer of flame-out assembly, which includes flame-out paste one 3 and flame-out paste two 4, the flame-out paste one 3 is arranged on the inner side of the upper cover 1, and the flame-out paste two 4 is arranged on the lower connecting plate 2 and is evenly spaced by the sliding grooves 5;

[0033] The sliding grooves 5 are slidingly connected with the partition plates 6, forming two separate spaces for separating the cables, the distance between the two flame-out paste layers two is the same as the thickness of the partition plates 6, and the height of the partition plates 6 is less than the distance between the upper cover 1 and the lower connecting plate 2, the partition plates 6 are arranged to isolate the two adjacent cables, allowing the cables to be classified.

[0034] By arranging the flame-out paste one 3 and the flame-out paste two 4, when the cable catches fire, the perfluorohexone fire extinguishing agent in the flame-out microcapsule inside the flame-out paste one 3 and the flame-out paste two 4 releases to extinguish the flame, the perfluorohexone fire extinguishing agent quickly vaporizes to take away heat, reduces the temperature around the flame, and forms an isolation layer to isolate oxygen, achieving suffocation of the flame and protecting the cable from spreading the fire;

[0035] By connecting the sliding blocks 7 at the bottom of the partition plates 6 with the sliding grooves 5, when the cable passes through the cable tray, the multiple cables inside the cable tray can be separated, avoiding the interlacing of the cables and increasing the difficulty of finding the cables, facilitating classification.

[0036] The inner side of the upper cover 1 is provided with a support 11, and the top of the support 11 is provided with a lifting assembly, which comprises a connecting block 10, both ends of the connecting block 10 are arranged at both sides of the support 11, and the support 11 is clamped and limited.
