Description

Technical Field

[0001] The utility model relates to the technical field of enclosed fireproof cable trays, and specifically relates to a water backflow prevention device for an enclosed fireproof cable tray. Background Technique

[0002] Common trough-type cable trays enter the power distribution cabinet from a high position. During the construction process or during fire extinguishing, due to water leakage in the pipe network or a large amount of fire sprinkler water, a certain amount of water will enter the cable tray and flow back into the distribution box, resulting in electrical short circuits, affecting the reliability of power supply. Therefore, the lines of the distribution cabinet are arranged through an enclosed fireproof cable tray. The enclosed fireproof metal cable tray is a professional line protection facility, which realizes the isolation and protection of the lines by covering a layer of professional fireproof material outside the ordinary metal cable tray, and has the high load-bearing capacity and stability of the metal cable tray.

[0003] However, the heat generated by the cables cannot be discharged through the set enclosed fireproof cable tray, which may lead to dangerous phenomena such as fires. In addition, the enclosed fireproof cable tray is not easy to open, affecting the maintenance and management of the cables. Content of the Utility Model
