Abstract
The utility model discloses a low-voltage cable fireproof groove box for cable channels, which comprises a fireproof groove box body and a fireproof groove box cover, wherein cable holes are formed at two ends of the fireproof groove box body for cables to pass through, and the fireproof groove box body and the fireproof groove box cover are made of glass fiber reinforced epoxy resin matrix composite materials; the fireproof groove box body comprises a pressing plate positioned on the cable hole; the improved fireproof groove box has good explosion-proof and corrosion-proof performance, and is suitable for being used in a cable channel to realize the isolation of different cables.
Description
Technical Field
The utility model relates to the technical field of cables, especially a low tension cable fire prevention groove box for cable channel.
Background
The power cable is mainly laid in an underground cable tunnel, due to the shortage of urban underground resources, the underground tunnel is mostly constructed by adopting a comprehensive tunnel (high voltage, low voltage and communication cable sharing), due to the fact that the high voltage, the low voltage and the communication cable are in the same channel, the fireproof problem of the cable is particularly important, once a fire condition occurs, large-area power failure is easily caused, and the influence range is extremely wide. Wherein the investigation shows that the explosion accident caused by the combustion of the low-voltage cable (such as communication cable and optical cable) accounts for more than half. Therefore, in the power part, the cable channel of the mixed high-voltage cable needs to be layered and erected by cables with different voltage grades and isolated by a fireproof groove box. However, the cable channel is often wet and even has accumulated water, and the commonly used metal fire-proof groove box is easy to corrode and even cause deflagration accidents.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a low-voltage cable fire prevention groove box for cable channel.
The utility model provides a technical scheme that its technical problem adopted is:
a low-voltage cable fireproof groove box for a cable channel comprises a fireproof groove box body and a fireproof groove box cover, wherein cable holes are formed in two ends of the fireproof groove box body and are used for cables to penetrate through, and the fireproof groove box body and the fireproof groove box cover are made of glass fiber reinforced epoxy resin matrix composite materials; the fire-proof slot box body comprises a pressing plate positioned on the cable hole.
The utility model has the advantages that: the improved fireproof groove box has good explosion-proof and corrosion-proof performance, and is suitable for being used in a cable channel to realize the isolation of different cables.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a perspective view of the present invention;
fig. 2 is a perspective view of the utility model with the fireproof box cover removed.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein.
Referring to fig. 1 and 2, the low-voltage cable fire-proof slot box for the cable channel comprises a fire-proof slot box body 1 and a fire-proof slot box cover 2, wherein cable holes 3 are formed in two ends of the fire-proof slot box body 1 and used for cables to penetrate through.
The fire-proof tank box body 1 and the fire-proof tank box cover 2 are made of glass fiber reinforced epoxy resin matrix composite materials. The glass fiber has good insulation property, strong heat resistance, good corrosion resistance and high mechanical strength, and the proportion and the preparation mode of the glass fiber reinforced epoxy resin matrix composite material can refer to the existing fireproof glass fiber reinforced epoxy resin matrix composite material, and are not described herein again. The improved fire-proof slot box body 1 and the improved fire-proof slot box cover 2 have enough explosion-proof and corrosion-proof effects and are suitable for the working environment of a cable channel.
The fireproof groove box body 1 comprises a pressing plate 4 located on the cable hole 3, the pressing plate 4 can compress a cable, the cable is prevented from loosening, and the phenomenon that the cable is corroded due to mutual friction and abrasion in the fireproof groove box body 1 is reduced. According to the above principle, the present invention can also make appropriate changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should fall within the protection scope of the claims of the present invention.
