The invention aims at disclosing a shielding structure for a ventilation pipeline of a spent fuel transport boat cargo hold. The shielding structure comprises a box-type shielding body or a pipeline-type shielding body positioned among a cargo hold cover through hole, a cargo hold wall through hole and a cover outer deck area through hole, and the shielding body is formed by steel plates or steeland polyethylene in a layered combined shielding mode. Compared with the prior art, the ventilation and heat exchange capacity is not reduced, the ventilation pipeline is compactly arranged, the shielding performance is good, the structure is simple, the cost is low, manufacturing and installation are convenient, and the purpose of the invention is achieved.
本发明的目的在于公开一种用于乏燃料运输船舶货舱通风管道的屏蔽结构,它包括位于货舱舱盖贯穿孔、货舱舱壁贯穿孔和舱盖外甲板区贯穿孔之间的箱体式屏蔽体或管道式屏蔽体,所述屏蔽体由钢板或钢和聚乙烯分层式组合屏蔽而成;与现有技术相比,不降低通风换热能力,围绕通风管道紧凑式布置,具有良好的屏蔽性能,结构简单,成本低廉,制造及安装方便,实现本发明的目的。
