Embodiment 1

[0027] Such as figure 1 As shown, a fireproof power cable trench of the present invention includes a plurality of assembled and connected trench bodies (two are shown in the figure) and a bracket 1 arranged in the trench body for providing support for cables. The fixed part of the channel body and the support part matched with the cable, the support part is an arc-shaped structure, and a single channel body is surrounded by a bottom plate 2, two side baffles 3 and a cover plate 4. 1. A hollow cuboid structure with both ends open; the bottom plate 2 is provided with a first slot 5 for accommodating the side baffle 3; the upper end of the side baffle 3 is provided with a second slot 6; The clamping strip 14 matched with the clamping groove 6 passes through the first matching part 7 and the second matching part between two adjacent bottom plates 2, between two adjacent side baffles 3, and between two adjacent cover plates. 8 sealing connection, the first mating part 7 and the se...

Embodiment 2

[0031] The structure of this embodiment is basically the same as that of Embodiment 1, the difference is: as image 3 As shown, the upper end surface of the cover plate 4 is an upwardly protruding arc structure with an arc of 5°. In this embodiment, the structure of the cover plate 4 is improved, which can effectively improve the compressive performance of the cover plate and facilitate the passage of heavy machinery.

Abstract

The invention belongs to the technical field of power facilities and particularly relates to a fireproof power cable trench. The fireproof power cable trench comprises multiple trench bodies; each trench body comprises a bottom plate, side baffles and a cover plate; one accommodating cavity and multiple discharge ports are arranged in the side baffles and on the cover plate; the discharge ports are located at the inner side of the cable trench; the accommodating cavity and the multiple discharge ports are communicated; the accommodating cavity is internally provided with a fireproof material;and the discharge port is provided with a plugging mechanism. Through improving the structure of the trench body, the accommodating cavity with the fireproof material is arranged in the side baffles and the cover plate, self extinguishing is carried out while waiting for rescue, and secondary fault of a power device is avoided.

Description

technical field [0001] The invention belongs to the technical field of power facilities, in particular to a fireproof power cable trench. Background technique [0002] The way of laying cables has transitioned from high-altitude suspension to underground laying, which has the advantages of safe construction and easy maintenance. Among them, the cable trench used to provide laying space generally adopts a concrete or brick structure, and its top is covered with a cover plate. The surface of the cover plate can be flush with the ground, which is easy to open, and some are slightly lower than the ground and a layer of cement is painted on the cover plate to prevent the cover plate from being uneven with the ground and rainwater from entering the cable trench. [0003] Since the cable trench is laid in the substation, when the substation equipment in the substation fails, such as a short circuit, the cable in the cable trench will heat up and catch fire, resulting in a larger po...
