Fireproof high-temperature-resistant sealing penetrating device for marine cable/pipeline

Abstract

The invention provides a fireproof high-temperature-resistant sealing penetrating device for a marine cable / pipeline. The device comprises a frame, and a plurality of cables or pipelines penetrate through the frame through a first opening end, penetrate out of the frame through a second opening end and are arranged in parallel. Each cable or pipeline is sleeved with a corresponding fireproof pipe sleeve, one end of each cable or pipeline retracts into the first opening end by a first preset distance, and the other end of each cable or pipeline retracts into the second opening end by a second preset distance; a fireproof sealing glue layer and a high-temperature-resistant sealing glue layer are sequentially laid at the first preset interval and the second preset interval from the end of the fireproof pipe sleeve, the fireproof sealing glue layer and the fireproof pipe sleeve can expand when a fire happens, the internal sealing performance of the frame is improved, spreading of flame, smoke and heat is blocked, and the A60-level fireproof performance is achieved.

Description

technical field [0001] The invention relates to the technical field of fireproof sealing of ship hulls, and more specifically, to a fireproof and high temperature resistant seal penetrating device for marine cables / pipelines. Background technique [0002] When the cable penetrates the deck and bulkhead of the ship, it will destroy its original protective integrity, so that the ship is always facing the threat of "fire" and "water" when sailing or mooring. The "fuse effect" formed will directly threaten the safety of the ship, and the consequences are very serious. In addition to the fire losses such as scrapping of basic equipment, instruments and data, it may further cause operation stoppage, equipment corrosion, personnel safety and health damage, etc., and even May cause the ship to sink. Therefore, during the laying of built-in cables on ships, it is necessary to seal the decks and bulkheads where the cables penetrate, so as to ensure that the watertight and fireproof i...

AI Technical Summary

Problems solved by technology

Therefore, the fire-resistant barrier pad 2 of this structure has no possibility of blocking the high-temperature fire from both ends of the cable / pipeline;

[0006] ②. The fireproof and high temperature resistance of refractory sealing packing 3 is poor. The temperature resistance level of refractory sealing packing 3 can only be used at a high temperature of about 200°C at most, and it cannot be used in the cabins of some special ships with high temperature of 300°C and alternating cold and hot Use in harsh environmental conditions;

[0007] ③. The pouring process of refractory sealing packing 3 is relatively complicated, and the disassembly and assembly of marine cables / pipelines is inconvenient
