[0002] Marine fire doors are an important part of ship safety facilities. Their main functions are to prevent the spread of fire, protect life safety and the hull structure. Currently, in order to ensure fire protection performance, marine fire doors usually adopt an integrally formed state and use a door closer to ensure that the marine fire door is always in a closed state. When a fire spreads to the marine fire door, the door closer is affected by high temperature, resulting in damage to the door closer, and thus the marine fire door is damaged and cannot be opened. The integrally formed marine fire door is also difficult to break, making it impossible for internal personnel to escape from the fire area in a timely and effective manner, further exacerbating the situation of casualties. At the same time, when firefighters conduct fire extinguishing operations inside the marine fire door, they are also easily affected by the integrally formed marine fire door and it is difficult to enter the fire area in time for fire extinguishing. It is also difficult to lay fire hoses to the corresponding fire area, seriously affecting the safety of marine fire doors.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides the following technical solution: a marine fire door. Please refer to Figures 1-4 , which includes a door frame 1. An inner skeleton 3 is installed inside the door frame 1. Inner skeletons 3 are installed at the central positions inside the door panels 2. Side longitudinal ribs 4 are installed on both sides inside the door panels 2. Rock wool 5 is installed between the opposite sides of the side longitudinal ribs 4 and the inner skeletons 3. The inner skeletons 3 and side longitudinal ribs 4 are laid inside and outside between the two door panels 2 in sequence, and the space between the inner skeletons 3 and side longitudinal ribs 4 is filled with rock wool 5. According to the fact that rock wool 5 is an excellent heat-insulating material, it can enhance the heat-insulating performance of the marine fire door. In case of a fire, it can effectively isolate high temperature, protect the safety of the space behind the door, and extend the time for escape and rescue. The door panel 2 is hinged to the door frame 1 through a hinge 6. A edging strip 7 is installed on the inner wall of the door frame 1. The edging strip 7 is located between the door frame 1 and the door panel 2. A sealing strip 8 is arranged inside the edging strip 7. A round window 9 is installed at the central position above the front end face of the door panel 2. A round window 9 is arranged above the end face of the door panel 2. According to the installed round window 9, it can provide a good view, enabling the crew to understand the external situation at any time. In addition, a protective glass can be installed on the round window 9 part. When a fire or smoke accumulates, breaking the window can effectively help reduce the accumulation of harmful gases and improve the survival probability of personnel.

[0022] An escape wind grid 10 is installed at the center position below the front end surface of the door panel 2, and a fire hose hole 11 is provided on one side below the front end surface of the door panel 2. The escape wind grid 10 and the fire hose hole 11 are arranged in sequence below the end surface of the door panel 2. According to the escape wind grid 10, more escape routes can be provided for the crew in an emergency, thereby improving the overall safety of the ship. In critical situations such as fire, one more escape route will help personnel evacuate faster and more safely, and it is also convenient for firefighters to enter the fire area in time to extinguish the fire, and try to avoid the situation that the marine fire door in the one-piece molding state is difficult to break through the door for escape and firefighting. At the same time, according to the fire hose hole 11, The pipe hole 11 provides a convenient access point, so that the fire water source can quickly enter the fire scene, which is convenient for the crew or firefighters to extinguish the fire in time and reduce the risk of fire spread. A door lock 12 is installed on one side of the center position of the front end face of the door panel 2, and a door closer lining 13 is installed above the front end face of the door panel 2. The door closer lining 13 is located above the round window 9. Frame pressure strips 14 are installed on the outer walls of both sides of the door frame 1. Screws 15 are rotatably connected between the frame pressure strips 14 and the door frame 1. Nuts 16 are threadedly connected to the upper and lower outer walls of the screws 15. Washers 17 are arranged above and below the outer walls of the screws 15, and the washers 17 are located between the two sets of nuts 16.

[0023] Working principle: When using the utility model, the inner and outer parts between the two groups of door panels 2 are paved with inner frames 3 and side longitudinal bones 4 in sequence, and the space between the inner frames 3 and the side longitudinal bones 4 is filled with rock wool 5. As the rock wool 5 is an excellent thermal insulation material, the thermal insulation performance of the marine fire door can be enhanced. When a fire occurs, it can effectively isolate high temperature, protect the safety of the space behind the door, and extend the time for escape and rescue. By arranging a round window 9 above the end face of the door panel 2, a good field of vision can be provided according to the installed round window 9, so that the crew can understand the external situation at any time. In addition, protective glass can be installed in the round window 9. When a fire occurs or smoke gathers, breaking the window can effectively help reduce the accumulation of harmful gases and improve the survival rate of personnel. By arranging an escape wind grille 10 and a fire hose hole 11 in sequence below the end face of the door panel 2, the escape wind grille 10 can provide more escape routes for the crew in an emergency. Path, thereby improving the overall safety of the ship. In critical situations such as fire, an additional escape route will help people evacuate faster and more safely, and it is also convenient for firefighters to enter the fire area in time to extinguish the fire, and try to avoid the situation where the marine fire door in the one-piece state is difficult to break through the door for escape and firefighting. At the same time, a convenient access point is provided according to the fire hose hole 11, so that the fire water source can quickly enter the fire scene, which is convenient for the crew or firefighters to extinguish the fire in time and reduce the risk of fire spreading. By combining these facilities with the design of marine fire doors, a more complete emergency system can be formed, and the comprehensive risk resistance of the ship can be improved. When facing emergencies such as fire, the crew can use these facilities to formulate more effective response strategies. The various additional functions of the marine fire door can improve the overall fire safety level of the ship and enhance the value retention and operational safety of the ship.
