Description

Technical Field

[0001] The utility model belongs to the technical field of cable trough boxes, and in particular relates to a visual cable fireproof trough box. Background Art

[0002] With the development of China's economy, power infrastructure is becoming increasingly sophisticated, and the number of cables being laid is increasing. Therefore, cable troughs / cable trays are being used to secure and organize the laid cables. In actual use, cable troughs have come into play, with increasing performance requirements. First, fire resistance is crucial. Cable troughs are densely packed with cables. A fire could damage the cables inside, or even spread along the cables, further intensifying the fire. Second, ease of maintenance is crucial. Power operators need to perform maintenance on a specific section of cable troughs. However, since the cables are laid inside the troughs, two people are required to lift the trough cover to inspect the cable lines. Furthermore, some troughs are located at a high position, making them difficult to transport, time-consuming, and labor-intensive, resulting in low maintenance efficiency.

[0003] Existing solutions:

[0004] (1) Use lightweight materials to manufacture fireproof trough boxes, such as highly flame-retardant polyester and high-density glass fiber materials;

[0005] (2) The cable trough box cover adopts a hinge design, and one side of the cover is connected to the cable trough box, which can be operated by one person to punch the cover;

[0006] However, all of the above solutions require opening the trough box cover to determine the internal cable status, so personnel need to open and check each cable one by one, which is time-consuming and labor-intensive, and has low maintenance efficiency. Moreover, the existing fireproof trough box still cannot meet high requirements in terms of fireproof performance. Utility Model Content

[0007] In order to solve the above technical problems, the purpose of the utility model is to provide a visual cable fireproof trough box, so that power operation and maintenance personnel can directly observe the cable status inside the trough box through the fireproof glass on the bottom / side without opening the trough box cover, thereby greatly improving the operation and maintenance efficiency; moreover, the composite fireproof structure in the fireproof trough box includes a metal plate, a polymer insulation layer and an aluminum foil layer. The metal plate provides rigid support, the polymer insulation layer can expand and insulate when exposed to fire, and the aluminum foil layer can reflect heat radiation, which greatly improves the fireproof performance of the cable fireproof trough box and can meet high fire protection requirements.

[0008] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0009] A visual cable fireproof trough box includes a trough box body and a trough box cover. The trough box body is a U-shaped structure, and the trough box cover is covered on the trough box body. Part of the structure of the trough box body is inlaid with fireproof glass. The trough box body and the trough box cover are both composite fireproof structures, which include metal plates, polymer insulation layers and aluminum foil layers.

[0010] Furthermore, the visual cable fireproof trough box also includes a cable bracket, which is fixed in the trough box body, and the cables placed in the fireproof trough box are supported on the cable bracket.

[0011] Furthermore, the cable bracket is an I-shaped bracket.

[0012] Furthermore, the bottom and sides of the trough box body are respectively inlaid with fireproof glass.

[0013] Furthermore, the inlaid connection between the fireproof glass and the trough box body is sealed and bonded by an expansion type fireproof sealant.

[0014] Furthermore, ventilation and drainage holes are provided on the bottom of the trough box body and the trough box upper cover.

[0015] Furthermore, the area around the ventilation and drainage holes is painted with fire-retardant paint or sprayed with fire-retardant sealant.

[0016] Furthermore, the thickness of the fireproof glass is greater than the wall thickness of the trough box body.

[0017] The beneficial effects of the utility model are:

[0018] The bottom and / or side of the trough box body of the utility model are inlaid with fireproof glass, so that power operation and maintenance personnel can directly observe the status of the cables inside the trough box through the fireproof glass on the bottom / side without opening the trough box cover, which greatly improves the operation and maintenance efficiency;

[0019] The trough box body and trough box cover of the fireproof trough box are both composite fireproof structures, which include metal plates, polymer insulation layers and aluminum foil layers. The metal plates provide rigid support, the polymer insulation layer can expand and insulate when encountering fire, and the aluminum foil layer can reflect heat radiation. The combination of the three-layer structure can greatly improve the fireproof performance of the cable fireproof trough box, so that the fireproof trough box can meet high fire protection requirements.

[0020] The top (trough box cover) and bottom (trough box body bottom) of the fireproof trough box are both provided with ventilation and drainage holes, which can provide a dry environment for cable operation. BRIEF DESCRIPTION OF THE DRAWINGS
