The invention belongs to the technical field of ventilation, and particularly relates to a ship inner cabin ventilation device, which comprises an air pipe, an air pipe air inlet vertical pipe, a ventilation bent pipe and an air outlet vertical pipe; wherein lock plates are fixedly connected between the front wall and the rear wall of the air inlet vertical pipe, the two lock plates are each provided with a plurality of transversely-formed lock grooves, and a stay wire pipe is arranged in the ventilation bent pipe; the rear end of the stay wire pipe extends into the air inlet vertical pipe and is connected with a locking mechanism, the front end of the stay wire pipe extends out of the air outlet vertical pipe and is connected with a plug plate mechanism, and the mass of the locking mechanism is larger than that of the plug plate mechanism. According to the ventilation device, the air pipe can be set to be in an open or closed state, the ventilation gap can be adjusted according to using requirements so as to adapt to different ventilation air volume requirements; the whole adjusting process is simple and convenient and the operation can be completed with one hand; in addition, when the air pipe is set to be in the closed state, pressure relief can be conducted when air pressure in the air pipe is too large, so that the safety is high.

    本发明属于通风技术领域,具体涉及一种船舶用内舱通风装置,包括风管,风管进风立管、通风弯管和出风立管,进风立管的前后壁之间均固定连接有锁板,两个锁板均设有若干个横向设置的锁槽,通风弯管内设有拉线管,拉线管的后端伸入进风立管内并连接有锁止机构,拉线管的前端伸出出风立管并连接有塞板机构,锁止机构的质量大于塞板机构的质量;该通风装置不仅能够将风管设置成打开或闭合状态,而且还能根据使用需要来调节通风间隙,以适应不同的通风风量需求,整个调节过程简单方便,单手便能完成操作,另外风管设置成关闭状态时能够在风管内部气压过大时进行泄压,安全性较高。
