The invention relates to the technical field of marine fireproof doors, and discloses a marine fireproof air-tight door which comprises a door frame, a door body is rotatably connected to the left side of the front end of the door frame, a rotating shaft is rotatably connected to the middle of the inner wall of the rear end of the door body, a gear is fixedly connected to the middle of a shaft body of the rotating shaft, and toothed plates are connected to the left end and the right end of the gear in an engaged mode. According to the fireproof door, the rotating disc is rotated to drive the rotating shaft and the gear to rotate, the gear rotates to drive the toothed plate and the sliding block to move up and down, when a fire occurs, the toothed plate drives the pressing plate and the sealing gasket to move, the gap between the door body and the door frame is sealed through the sealing gasket, and smoke or harmful gas is prevented from penetrating through the gap and diffusing; the sealing gasket can be repeatedly used, the environment temperature is monitored in real time through the temperature sensor, when a fire disaster happens and the environment temperature rises to a set safety value, the alarm can give an alarm and give an early warning in time, and the sealing gasket is worthy of being vigorously popularized.

    本发明涉及船用防火门技术领域,公开了一种船用防火门密闭门,包括门框,所述门框的前端左侧转动连接有门体,所述门体的后端内壁中部转动连接有转轴,所述转轴的轴体中部固定连接有齿轮,所述齿轮的左右两端均啮合连接有齿板。本发明中,通过转动转盘带动转轴和齿轮转动,通过齿轮转动带动齿板和滑块上下移动,在发生火灾时,通过齿板带动压板和密封垫移动,通过密封垫对门体与门框之间的空隙进行密封,防止烟雾或有害气体穿过缝隙并扩散,密封效果好并且密封垫可以重复使用,通过温度传感器对环境温度进行实时监测,当发生火灾,环境温度升高到设定的安全值时,报警器会发出警报,及时做出预警,值得大力推广。
