Fireproof nonmetal cable bridge

Abstract

The invention discloses a fireproof nonmetal cable bridge, and the cable bridge comprises a temperature sensing optical fiber, a pouring layer and a groove-shaped bridge body; the groove-shaped bridgebody is provided with a bottom plate and two side plates, the two side plates are arranged on the two sides of the bottom plate in parallel in the length direction of the bottom plate, the pouring layer is poured on the bottom plate, and the pouring layer and the two side plates form an open containing groove; the open accommodating groove is used for accommodating a cable; and the temperature sensing optical fiber is pre-buried in the pouring layer along the length direction of the open accommodating groove. According to the fireproof nonmetal cable bridge provided by the invention, the temperature sensing optical fiber is pre-buried in the pouring layer and is connected with the external temperature demodulator, so that the real-time temperature and the temperature change condition of each point on the cable bridge can be monitored in real time, and an alarm is given and accurate positioning is carried out when an abnormality is found; the pouring layer cannot be burnt and has a fireproof function; and the temperature sensing optical fiber is pre-buried in the pouring layer, so that the labor intensity of cable laying workers is reduced, and the cable bridge is convenient to reuse.

Description

technical field [0001] The invention relates to the technical field of cable bridges, in particular to a fireproof non-metallic cable bridge. Background technique [0002] Cable trays are divided into two categories according to materials: metal and non-metal, and according to types: trough bridges, tray bridges, stepped bridges, combined bridges, long-span bridges, new bolt-free bridges, etc. Non-metallic cable tray, referred to as clear frame. This new FRP cable tray uses flame-retardant synthetic resin as the adhesive and glass fiber as the reinforcing material. It has high corrosion resistance, electrical insulation performance, light weight, high strength, and good flame retardancy. , bright and beautiful color, reliable use and other excellent characteristics. It is suitable for chemical industry, mine, and salt spray corrosion area; the use of FRP cable tray can not only save a lot of steel, but also save a lot of maintenance costs, reduce labor intensity, and prolo...

Problems solved by technology

However, in some existing non-metallic cable trays, cables are laid in various cable trays, and after the cables are put into use, if a certain section of cable laid in the cable tray catches fire due to a short circuit, then the management personnel cannot find out the fire in time. This will bring serious harm. There are also some existing temperature-sensing optical fibers laid on the bottom or side of the cable bridge to sense the temperature of each place, so as to judge which place has a higher temperature, but laying temperature-sensing optical fibers on the cable The bottom or side of the bridge, on the one hand, occupies the space for cable laying, and on the other hand increases the labor intensity of the relevant cable laying staff. If the cable needs to be replaced and the cable is removed, the laid temperature-sensitive optical fiber needs to be removed together, which increases the work. Work intensity
