The invention belongs to the technical field of ship ventilation pipelines and discloses an anti-irrigation device for a ship ventilation pipeline. A supporting plate (120) is arranged on the outer wall of a pipeline body (110) of the ventilation pipeline (100), a hinged support (130) is arranged on the side wall of the top end of the pipeline body (110), the bottom of a shell (210) of the protection shell (200) is arranged on the supporting plate (120), a ventilation opening (220) is formed in the bottom of the side wall of the shell (210), a lever (310) of the floating sealing piece (300) is rotationally connected to the hinged support (130), a floating ball (320) is arranged at the lower end of the lever (310), and a turning cover (330) is arranged at the upper end of the lever (310). According to the anti-irrigation device for the ship ventilation pipeline, reliable ventilation is achieved, rainwater and sea waves are prevented from entering the pipeline body, the situation that the lower water level rises and is poured into the pipeline body can be avoided, and the safety of a ship is guaranteed.

    本发明属于船舶通风管道技术领域的船舶通风管道防灌水装置。通风管道(100)的管道本体(110)外壁设置支撑板(120),管道本体(110)顶端侧壁设置铰座(130),防护壳(200)的壳体(210)底部设置在支撑板(120)上,壳体(210)侧壁底部开设通风口(220),浮动封闭件(300)的杠杆(310)转动连接在铰座(130)上,杠杆(310)下端设置浮球(320),杠杆(310)上端设置翻盖(330)。本发明所述的船舶通风管道防灌水装置,既实现可靠通风,又避免雨水和海浪进入管道本体,还能够避免下方水位升高而灌入管道本体,保障船舶安全。
