The invention provides a hatch structure with a fireproof air brake, and relates to the field of fireproof air brakes. The hatch structure with the fireproof air brake comprises a hatch coaming, an air brake plate and a locking structure. The air brake plate is installed on the upper side of the hatch coaming in a hinged mode, and a stopping structure is further arranged on the air brake plate andused for being matched with the hatch coaming in a stopping mode when the air brake plate is in a hatch closing state; a fixed pulley is arranged above the hatch coaming; a movable pulley is installed on the upper side of the air damper plate, a flexible rope is connected among the stopping structure, the movable pulley and the fixed pulley, the other end of the flexible rope is provided with anoperation part used for pulling down, the flexible rope is further provided with a locking matching part, and the locking matching part is used for being matched with the locking structure in a locking mode when the air damper plate is in an open-hatch state. When a fire occurs in a fan or a cabin, the locking structure is unlocked from the locking matching piece, and the air brake plate quickly moves towards the closing position due to the gravity of the air brake plate so that the aim of closing the air brake plate more quickly and reliably can be fulfilled, and the fireproof safety is higher.
本发明提供了一种带防火风闸的舱口结构,涉及防火风闸领域。带防火风闸的舱口结构包括舱口围板、风闸板以及锁止结构,风闸板铰接安装在舱口围板的上侧,风闸板上还设有挡止结构,挡止结构用于在风闸板处于关闭舱口状态时与舱口围板挡止配合;舱口围板的上方设有定滑轮,风闸板的上侧安装有动滑轮,挡止结构、动滑轮以及定滑轮之间连接柔性绳索,柔性绳索的另一端设有用于向下拉动的操作部,柔性绳索上还设有锁止配合件,锁止配合件用于在风闸板处于开启舱口时与锁止结构锁止配合。当风机或机舱发生火灾时,使锁止结构解除与锁止配合件的锁止配合,风闸板由于自身重力朝关闭位置快速运动,能够达到更快、更可靠关闭的目的,防火安全性更高。
