The invention discloses a ventilation groove structure of a ship ballast tank, which comprises a ventilation groove structural body, the ventilation groove structural body is fixedly connected with a cargo compartment bottom plate and a ballast tank side wall and extends outwards from a bottom ballast tank to a side ballast tank area, and the inner side end of the ventilation groove structural body is communicated with the bottom ballast tank; the air pipe is vertically fixed in the side ballast tank, the upper section of the air pipe upwards penetrates out of the deck and is communicated with the outside atmosphere, and the lower section of the air pipe is fixedly connected and communicated with the outer side end of the ventilation groove structural body. Air at the top of the ballast tank can completely permeate, and a free liquid level cannot be formed in the ballast tank, so that ship stability is facilitated; the ballast tanks can be fully filled, so that the number of the ballast tanks of the ship can be reduced, and more cargo carrying space is reserved; the top area of the ballast tank is filled with water all the time, and the tank wall cannot be exposed in humid air and is not prone to corrosion; no residual air is left in the ballast tank, and extra pressure cannot be generated on the bulkhead due to thermal expansion and cold contraction of gas when the environment temperature changes.
本发明公开了一种船舶压载舱的透气槽结构,包括:透气槽结构体,透气槽结构体固定连接货舱底板和压载舱侧壁,并由底压载舱向外侧延伸至边压载舱区域,其内侧端与底压载舱接通;空气管,空气管竖直固定于边压载舱中,其上段向上穿出甲板并与外界大气连通,其下段固定连接并连通透气槽结构体的外侧端。压载舱顶部空气可以完全透出,压载舱内不会形成自由液面,利于船舶稳性;压载舱可以完全注满,使得船舶可以减少压载舱的数量,留下更多的载货空间;压载舱顶部区域一直充满水,舱壁不会暴露在潮湿的空气中不容易产生腐蚀;压载舱无残留空气,环境温度变化时不会由于气体的热胀冷缩对舱壁产生额外的压力。
