Technical Field
[0001] This utility model relates to the field of fire protection equipment technology, specifically a lifting cable tray fire extinguishing device. Background Technology
[0002] Cable trays are crucial equipment in chemical plants. With increasing service life, the insulation material surrounding the cables within the trays is prone to aging. Under high-load conditions, this aging insulation can easily ignite, leading to a fire. Cable trays are typically installed at a height of around 5 meters. In the early stages of a cable tray fire, because power is still available, water spray cannot be used for extinguishing. However, early fire suppression is critical. Due to the height of the cable trays, it is difficult for workers on the ground to effectively direct dry powder fire extinguishers to the ignition point. Therefore, the current method of extinguishing the fire involves manually sending the hose of a dry powder fire extinguisher or a wheeled fire extinguisher onto the cable tray. This process requires operators to climb onto the cable tray, posing a significant safety hazard. Utility Model Content
