Description

Technical Field

[0001] This utility model is a sealing structure for marine fireproof doors and windows, belonging to the field of marine fireproof doors and windows. Background Technology

[0002] Fire-resistant doors and windows are important fire protection facilities on ships, playing a crucial role in ensuring the safety of the ship and its personnel. To prevent smoke from entering the interior through fire-resistant doors and windows during a fire, sealing mechanisms are installed.

[0003] In existing technologies, most marine fireproof doors and windows require turning the door handle to disengage the locking block from the door frame before opening. However, during a fire, the high temperature can cause the door handle to heat up, resulting in burns if the hand touches the handle directly. Some fireproof doors use a foot-operated mechanism to turn the door open, but in a fire emergency, crew members may instinctively press the door handle due to their usual door-opening habits, causing burns. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a sealing structure for fireproof doors and windows for ships to solve the problems mentioned in the background art. This utility model can automatically block the door handle in the event of a fire and open the door by stepping on it, thus preventing burns to the hands of crew members.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a marine fireproof door and window sealing structure, including a door frame and a lever, wherein a door panel is movably connected to one side of the door frame via a hinge, a glass plate is fixed to one side of the door panel, and a deadbolt mechanism is provided in the middle of one side of the door frame.

[0006] A sealing ring is slidably connected to one side of the door frame, and a tension spring is fixed to one end of the sealing ring. One end of the tension spring is fixed to the door frame. A wedge-shaped groove matching the sealing ring is opened on one side of the door panel. A driving mechanism is provided on the side of the door frame near the sealing ring, and a reinforcing sealing mechanism is provided on one side of the door panel.

[0007] Furthermore, the driving mechanism includes a pressing block that is slidably connected to one side of the door frame. One end of the pressing block abuts against a lever. Both sides of the lever are movably connected to the door frame via a rotating shaft. The sealing ring has a moving groove inside, and the moving groove is slidably connected to the lever.

[0008] Furthermore, the enhanced sealing mechanism includes a high-temperature expansion strip that abuts against one side of the sealing ring, and a groove matching the high-temperature expansion strip is provided on one side of the sealing ring. One side of the high-temperature expansion strip is fixed to the door panel.

[0009] Furthermore, the door panel is movably connected to a connecting shaft via a bearing. A cleaning brush is welded and fixed to one end of the connecting shaft, and a ceramic fiber felt is fixed to one side of the cleaning brush. A handle is slidably connected to the other end of the connecting shaft, and a limit mechanism is provided on one side of the handle.

[0010] Furthermore, the limiting mechanism includes a limiting block welded and fixed to one side of the handle, and a limiting groove matching the limiting block is opened on one side of the door panel, and a magnet is fixed inside the limiting groove.

[0011] Furthermore, the locking mechanism includes a rotating block that is movably connected to the inside of the door panel via a bearing. One end of the rotating block is connected and fixed to an elliptical block. Multiple sets of arc-shaped grooves are opened on the outer side of the elliptical block. A locking block abuts against one side of the elliptical block. One end of the locking block is arc-shaped. The other end of the locking block is engaged with the door frame. A reset mechanism is provided on the outer side of the locking block.

[0012] Furthermore, the reset mechanism includes a fixing plate welded and fixed to the outside of the card block, a spring a abutting on one side of the fixing plate, and one end of the spring a abutting against the door frame.

[0013] The beneficial effects of this utility model are:

[0014] 1. The ship uses a fireproof door and window sealing structure. In the event of a fire, the high temperature will cause the handle to heat up. To prevent crew members from being burned when turning the lever to open the door, a foot pedal can be used. The pedal will rotate and compress a spring b on one side. The top of the pedal will pull the lever through a steel wire rope to rotate and open the door. When there is a fire, the temperature in the fixing block will rise. The memory spring in the fixing block is made of nickel-titanium alloy, a memory metal. Under high temperature, it will deform and extend, thereby pushing the locking block to move and disengage it from the limit rod. At the same time, the locking block will compress the return spring. At this time, the limit rod and the cover will move down to block the lever and prevent crew members from turning the lever. The cover is made of aerogel composite material with extremely low thermal conductivity, which can maintain a low temperature in high-temperature environments and prevent crew members from being burned when they come into contact with the cover.

[0015] 2. As the door panel is about to close, it will first contact the pressing block, causing it to move and push the lever at one end. The lever will rotate and move the sealing ring. The sealing ring will then pull the tension spring on one side to stretch. When the door panel is fully closed, the bevel at one end of the sealing ring will fit into the wedge groove inside the door panel. Since the sealing ring is annular, it will seal the connection between the door panel and the door frame. In this way, the fire door can be easily sealed in case of fire. Attached Figure Description

One side of the pressing block 7 has a set of protrusions that can limit the movement range of the pressing block 7 and prevent the pressing block 7 from leaving the interior of the door frame 1. The interior of the door frame 1 has a rotating groove that matches the lever 8, which allows the lever 8 to rotate, thereby moving the sealing ring 5.

[0029] Please see Figure 1 , Figure 3 and Figure 7 The door panel 2 is internally connected to a connecting shaft 12 via a bearing. A cleaning brush 10 is welded and fixed to one end of the connecting shaft 12, and a ceramic fiber felt 11 is fixed to one side of the cleaning brush 10. A handle 13 is slidably connected to the other end of the connecting shaft 12. A limit mechanism is provided on one side of the handle 13, and a moving groove matching the connecting shaft 12 is opened at one end of the handle 13. The connecting shaft 12 and the handle 13 form a sliding structure. The limit mechanism includes a limit block 14 welded and fixed to one side of the handle 13. A limit groove matching the limit block 14 is opened on one side of the door panel 2, and a magnet 15 is fixed inside the limit groove. The limit block 14 is made of magnetic material, so it can be attracted and fixed with the magnet 15, thereby limiting the handle 13. The limited handle 13 can be prevented from moving randomly.

[0030] Please see Figure 1 , Figure 4 and Figure 5The locking mechanism includes a rotating block 16 that is movably connected to the inside of the door panel 2 via a bearing. One end of the rotating block 16 is fixedly connected to an elliptical block 17. Multiple sets of arc-shaped grooves are opened on the outer side of the elliptical block 17. One side of the elliptical block 17 abuts against a locking block 18. One end of the locking block 18 is arc-shaped, and the other end of the locking block 18 is engaged with the door frame 1. A reset mechanism is provided on the outer side of the locking block 18. The inside of the door panel 2 is provided with a sliding groove that matches the locking block 18. The locking block 18 and the door panel 2 form a sliding structure. The reset mechanism includes a fixing plate 19 that is welded and fixed to the outer side of the locking block 18. One side of the fixing plate 19 abuts against a spring a20. One end of the spring a20 abuts against the door frame 1. One side of the door frame 1 is provided with a locking groove that matches the locking block 18, which can limit the locking block 18. The spring a20 can reset and push the locking block 18 to engage with the door frame 1.

[0031] Please see Figure 1 , Figure 2 , Figure 4 and Figure 6In specific implementation, the ship uses a fireproof door and window sealing structure. During a fire, the high temperature will cause the pull rod 21 to heat up. To prevent crew members from being burned when turning the pull rod 21 to open the door panel 2, they can step on the pedal 23. The pedal 23 will rotate, compressing a spring b24 on one side. The top of the pedal 23 will then pull the pull rod 21 via the steel wire rope 22, thus opening the door panel 2. To prevent crew members from unconsciously turning the pull rod 21 during a fire, a set of shielding covers 27 is installed at the top of the pull rod 21. When the temperature in the fixing block 25 rises during a fire, the fixing... The memory spring 29 in block 25 is made of nickel-titanium alloy, a shape-memory metal. It deforms and stretches at high temperatures, pushing the locking block 28 to move and disengage from the limiting rod 26. Simultaneously, the locking block 28 compresses the return spring 30. At this point, the limiting rod 26 and the cover 27 move downwards, blocking the pull rod 21 and preventing the crew from rotating it. Furthermore, the cover 27 is made of aerogel composite material with extremely low thermal conductivity, maintaining a low temperature even in high-temperature environments and preventing burns to the crew upon contact. When the door panel 2 is about to close, it will first contact the pressing block 7, causing it to move and push the lever 8 at one end. The lever 8 will rotate and move the sealing ring 5. The sealing ring 5 will then pull the tension spring 4 on one side. When the door panel 2 is fully closed, the bevel at one end of the sealing ring 5 will fit into the wedge-shaped groove 6 inside the door panel 2. Since the sealing ring 5 is annular, it will seal the connection between the door panel 2 and the door frame 1. Because the sealing ring 5 is made of high-temperature resistant metal, it will not be affected by fire. When the door panel 2 needs to be opened, the door panel 2 will disengage from the pressing block 7. When the tension spring 4 pulls the sealing ring 5 to reset, it disengages from the wedge groove 6 and retracts into the door frame 1, preventing the door panel 2 from colliding and interfering with the sealing ring 5 when it is turned open. In order to further improve the sealing ability in case of fire, a set of high-temperature expansion strips 9 are set inside the door panel 2. The high-temperature expansion strips 9 are made of ceramic fiber, with aluminum silicate fiber as the base material, and high-temperature resistant adhesive and expansion agent are added. The maximum temperature resistance can reach 1600℃. When the high-temperature expansion strips 9 come into contact with high temperature, they will expand, thereby filling the groove on one side of the sealing ring 5 and completing the secondary seal.

[0032] Please see Figure 1 , Figure 3 and Figure 7After the fire is over, glass plate 3 is needed to view the outside situation. The ash produced by the fire will obstruct glass plate 3. In order to remove this ash, the handle 13 is pulled to move at the end of the connecting shaft 12, which will cause the limiting block 14 to disengage from the magnet 15 and disengage from the door panel 2. Then the handle 13 can be rotated to drive the cleaning brush 10 to rotate. The ceramic fiber felt 11 on one side of the cleaning brush 10 is a common refractory material. It is made of selected aluminosilicate ceramic fiber cotton as the main raw material and is made by wet molding or needle punching process. It can be used for a long time in a high temperature environment of 1000℃-1400℃ and is soft. After contacting the glass plate 3, it will remove the ash on the glass plate 3. Then, the outside situation can be viewed through the glass plate 3 without opening the door panel 2.

[0033] Please see Figure 1 , Figure 4 and Figure 5 When locking the door panel 2, rotating the rotating block 16 causes the elliptical block 17 to rotate as well. When the longer side of the elliptical block 17 presses against the locking block 18, the locking block 18 moves and engages with the door frame 1. The outer fixing plate 19 then presses against the spring a20. When it is necessary to open the door panel 2, the elliptical block 17 can be rotated so that the shorter side contacts the locking block 18. At this time, the spring a20 can push the locking block 18 to reset and disengage from the door frame 1. This operation facilitates the sealing of the fire door in case of fire.

Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
