Embodiment 1

[0023] Such as Figure 1-2 As shown, a kind of anti-smoke and fire entrapment device for a cable trench includes a wall 1 and a cable trench 2. The upper end of the cable trench 2 is provided with a cover plate 3, and one end of the cable trench 2 is fixedly connected to the wall 1. The above is the prior art. I won't go into too much detail here.

[0024] There is a storage cavity 4 inside the cover plate 3, and the storage cavity 4 is filled with silver bromide powder. The silver bromide powder will decompose and generate a large amount of gas when exposed to light, and the reverse reaction will occur when it is protected from light. It should be noted that the storage The upper side wall of cavity 4 is transparent.

[0025] Bellows 5 are fixedly connected between the lower bottom surface on both sides of the cover plate 3 and the upper side wall of the cable trench 2, and each bellows 5 communicates with the storage cavity 4 through a conduit 6 arranged in the cover plate ...

Embodiment 2

[0034] Such as Figure 3-4 As shown, the difference between this embodiment and Embodiment 1 is that the upper side wall of the cover plate 3 is fixedly connected with a vertical rack 14, and the upper end of the rack 14 extends to the outside of the transparent cover 11 and is fixedly connected with a warning flag. 15. Play a warning role.

[0035] An exhaust fan 16 is fixedly installed in the side wall of the transparent cover 11, and the rotating shaft of the exhaust fan 16 extends into the transparent cover 11 and is fixedly connected with the wall 1. The rotating shaft of the exhaust fan 16 is fixedly sleeved with a rack 14 The gear 17 that meshes the connection.

[0036] It should be noted that the outer wall of the transparent cover 11 is provided with a short pipe 18 matched with the exhaust fan 16, and a one-way valve is installed in the short pipe 18, which can prevent outside air from entering the transparent cover 11 and cause delayed backflow. .

Abstract

The invention belongs to the field of cable trenches, and in particular relates to a fire and fire prevention device for cable trenches. A storage cavity is opened in the cover plate, and the storage cavity is filled with silver bromide powder. Corrugated pipes are fixedly connected between the lower bottom surfaces on both sides of the cover plate and the upper side walls of the cable trench. They are all communicated with the storage cavity through conduits arranged in the cover plate. The wall is provided with a communication hole that communicates with the cable trench. The bottom surface of the communication hole is fixedly connected with a vertically arranged baffle plate. A vertically arranged push rod is fixedly connected to the side wall, and the lower end of the push rod extends to the interior of the baffle plate. By setting the exhaust fan, the rack will drive the exhaust fan to rotate during the downward movement of the cover plate, so that the smoke in the transparent cover can be sucked, and a small amount of the smoke that has entered the room can be sucked out. Further improve the smoke barrier effect.

Description

technical field [0001] The invention belongs to the field of cable trenches, in particular to a device for preventing smoke and fire from entering a room for cable trenches. Background technique [0002] The cable trench is a kind of trench for containing cables inside. Some cable trenches also have the function of drainage, and some cable trenches are specially used for the storage of cables. They are generally set below the ground, and there are multiple covers that are spliced ​​together at the port. plate. [0003] Most of the traditional cable trenches and building walls will have communication holes at the junction to allow the cables to penetrate into the room. However, the cables in the cable trenches will inevitably cause fire due to local overheating during long-term use. The upper end of the cable trench is closed with a cover plate Therefore, the smoke generated by combustion can easily enter the room through the communication hole. The gas generated by cable co...
