Marine cable/pipeline fireproof nuclear shielding sealing penetration device

Abstract

The invention provides a marine cable / pipeline fireproof nuclear shielding sealing penetration device, which comprises a frame, and each of a plurality of cables or pipelines penetrates through the frame from a first opening end and penetrates out from a second opening end; the cables or pipelines are sleeved with corresponding anti-radiation fireproof sleeves, the ends of the anti-radiation fireproof sleeves are flush, one end of each anti-radiation fireproof sleeve retracts into the first opening end by a first preset distance, and the other end of each anti-radiation fireproof sleeve retracts into the second opening end by a second preset distance. A nuclear radiation shielding layer and an anti-radiation fireproof sealing glue layer are sequentially laid at the first preset interval and the second preset interval from inside to outside from the end of the anti-radiation fireproof sleeve respectively, and the nuclear radiation shielding layer, the anti-radiation fireproof sealing glue layer and the anti-radiation fireproof sleeve can expand when a fire breaks out. The internal sealing performance of the frame is improved, spreading of flames, smog 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 particularly, to a fireproof nuclear shielding and sealing penetration device for marine cables / pipes. Background technique [0002] With the rapid development of military and civilian nuclear equipment and nuclear facilities, the signals transmitted between various systems and equipment are complex and diverse, which puts forward new requirements for the comprehensive transmission capability and reliable operation of transmission cables in the use environment of nuclear radiation. [0003] Chinese invention CN201510797539.9 proposes a special integrated cable for combat vehicles, such as figure 1 As shown, the integrated cable is bundled by anti-nuclear cable 1, CAN bus cable 2, power cable 3, and signal cable 4. The wire harness is wrapped with special waterproof tape as a waterproof layer 5, and the waterproof layer 5 is braided with an anti-nuclear shielding l...

AI Technical Summary

Problems solved by technology

[0006] ① Anti-nuclear cable 1, CAN bus cable 2, power cable 3, and signal cable 4 are wrapped in the waterproof layer 5. There is no fireproof, waterproof and nuclear radiation-proof design at both ends of the wiring harness. Therefore, this structure has no possibility to block the cables from / The high-temperature fire at both ends of the pipeline cannot be waterproof and anti-nuclear radiation;

[0007] ②. The fireproof performance of waterproof layer 5, shielding layer 6 and sheath layer 7 is poor, and cannot meet the use requirements of A60 fireproof grade
