Description

Technical Field

[0001] This utility model relates to the field of fireproof slot box technology, and in particular to a fireproof slot box with active fire extinguishing function. Background Technology

[0002] In existing technologies, after the fireproof cable tray is used, if the cables inside catch fire, they can self-extinguish due to oxygen depletion caused by the sealed structure. External fires will also not affect the cables inside due to the non-combustible nature of the tray material. However, fires inside the fireproof cable tray require the oxygen to be completely exhausted before they can be extinguished, making the fire suppression method relatively passive. To address this issue, a patent document, such as publication number CN222723497U, discloses a fireproof cable tray with active fire suppression function. This solution provides a fireproof cable tray capable of active fire suppression, but its chamber is open from side to side. If an anomaly occurs, the wax sealant on it is difficult to react quickly, which also affects the spraying of the fire extinguishing material, resulting in a slow response, poor fire suppression effect, and difficulty in forming an effective fire barrier. Similarly, there is a novel fireproof trough box with active fire extinguishing function disclosed in patent document CN220676576U. The difference between this solution and the above solution is that this solution uses a detection signal to trigger a pressing mechanism to isolate the two ends of the fireproof trough box to achieve fire prevention. However, this solution requires electricity to function, which has significant limitations, a cumbersome structure, and is too idealistic.

[0003] To address the aforementioned issues, a fireproof trough with active fire suppression function is provided. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a fireproof trough with active fire extinguishing function, which effectively solves the problems of existing fireproof troughs that require external detection signals to trigger the fire extinguishing mechanism, have poor active fire extinguishing efficiency, are difficult to form effective isolation, and are too idealistic.

[0005] The technical solution includes a horizontal rectangular tube with multiple fire extinguishing units evenly distributed inside. Each fire extinguishing unit includes two interlocking arc-shaped plates. A movable plate is hinged to the inner wall of the rectangular tube via a torsion spring. An arc groove is formed on the side of the movable plate near the arc-shaped plate, and the middle of the arc groove is hinged to the outer wall of the arc-shaped plate via a torsion spring. A fire extinguishing layer rich in sodium hydroxide is provided on the inner wall of the arc-shaped plate.

[0006] Preferably, the inner side of the arc-shaped plate is provided with raised strips, and the fire extinguishing layer fills the grooves formed between adjacent raised strips.

[0007] Preferably, when two movable plates within the same fire extinguishing unit are in a vertical position, the edges of the two movable plates are in close contact with each other.

[0008] Preferably, the edges of the movable plates are provided with sealing strips.

[0009] Preferably, the rectangular tube is detachable.

[0010] This utility model has a clever structure that can form multiple partitioned spaces within the fireproof cable tray chamber, adapting to wires of different specifications and self-adaptively clamping onto the wires. When an abnormality occurs, after the flames enter the fireproof cable tray chamber, the burning area remains in a state of oxygen deficiency, making it difficult for the flames to pass through the cable tray chamber, thus achieving active fire extinguishing of the wires and cables.

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0018] Depend on Figures 1 to 6 The present invention includes a horizontal rectangular tube 1, in which multiple fire extinguishing units are evenly distributed; each fire extinguishing unit includes two interlocking arc-shaped plates 2, and a movable plate 3 is hinged to the inner side wall of the rectangular tube 1 via a torsion spring. The movable plate 3 has an arc groove on the side near the arc-shaped plate 2, and the middle of the arc groove is hinged to the outer side wall of the arc-shaped plate 2 via a torsion spring; a fire extinguishing layer 4 rich in sodium hydroxide is provided on the inner side wall of the arc-shaped plate 2.

[0019] In order to hold enough fire extinguishing material, the inner side of the arc-shaped plate 2 is provided with raised strips 5, and the fire extinguishing layer 4 fills the grooves formed between adjacent raised strips 5.

[0020] In order to divide the chamber of the rectangular tube 1 into multiple parts, when the two movable plates 3 in the same fire extinguishing unit are in a vertical state, the edges of the two movable plates 3 are close to each other.

[0021] To better isolate the rectangular tube 1 chamber, sealing strips 6 are provided on the edges of the movable plate 3.

[0022] For ease of installation, the rectangular tube 1 is detachable.

[0023] There are many ways to assemble and disassemble the rectangular tube 1, such as using a U-shaped plate to fasten a flat plate to form the rectangular tube 1 structure, which is convenient for installation.

[0024] When the torsion springs on the movable plate 3 and the rectangular tube 1, as well as the torsion springs hinged between the arc groove and the arc plate 2, are not subjected to external forces, the axis of the arc plate 2 is perpendicular to the movable plate 3, and the movable plate 3 is in a vertical state.

[0025] It is worth noting that although the distance between the two arc plates 2 in this scheme can accommodate wires and cables of different specifications, in order to divide the rectangular tube 1 chamber into multiple independent areas, it is best if the diameter of the cable is equal to or slightly larger than the diameter of the arc plate 2, so that the arc plate 2 can clamp the wire.

[0026] In use, a wire of appropriate size is passed through the rectangular tube 1. The wire passes through multiple fire extinguishing units in sequence. Two arc-shaped plates 2 in the fire extinguishing unit surround the wire. When the wire catches fire, the high temperature causes the sodium hydroxide in the fire extinguishing layer 4 inside the arc-shaped plate 2 to quickly generate a large amount of carbon dioxide, thus extinguishing the fire. Even if the flame breaks through the previous fire extinguishing unit and reaches the next fire extinguishing unit, the space between the two fire extinguishing units will heat up rapidly. The carbon dioxide generated by the high temperature will cause the air pressure inside the cavity to increase rapidly. The airflow will blow outward from the gap between the metal wire and the arc-shaped plate 2, reducing the fire and thus extinguishing the fire area.

[0027] During the above process, since the air pressure inside the rectangular cylinder 1 is greater than that outside, the airflow flows outward from the molten part of the cable, causing the molten cable material to seal the gap between the arc plate 2 and the cable wires again, thereby achieving the purpose of extinguishing the fire.

[0028] This utility model has a clever structure that can form multiple partitioned spaces within the fireproof cable tray chamber, adapting to wires of different specifications and self-adaptively clamping onto the wires. When an abnormality occurs, after the flames enter the fireproof cable tray chamber, the burning area remains in a state of oxygen deficiency, making it difficult for the flames to pass through the cable tray chamber, thus achieving active fire extinguishing of the wires and cables.
