DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] The present utility model provides a Figures 1-4 shown sound insulation marine fire door, including a door frame 1 and a sound insulation door body 2. The sound insulation door body 2 is movably arranged inside the door frame 1 through a pin shaft. A cavity 3 is arranged inside the sound insulation door body 2. Observation windows 4 are arranged through both top ends on both sides of the cavity 3. A fixed frame 5 is fixedly arranged in the middle of the inner side of the cavity 3, and the top end of the fixed frame 5 corresponds to the observation window 4;
[0023] Specifically, an active baffle 6 is arranged inside the fixed frame 5, and the active baffle 6 corresponds to the observation window 4. The bottom end of the fixed frame 5 is fixedly provided with an air guide cavity 7. A piston 8 is arranged inside the air guide cavity 7, and the piston 8 is fixedly arranged at the bottom end of the active baffle 6. The piston 8 can be pushed upward under the action of the expanding gas.
[0024] More specifically, a gas guide pipe 9 is fixedly arranged at the bottom end of the air guide cavity 7. One end of the gas guide pipe 9 is fixedly provided with an expansion airbag 10. A communication pipe 11 is arranged between the expansion airbag 10 and the gas guide pipe 9. A diaphragm is arranged inside the communication pipe 11. The diaphragm can play a role in sealing the expansion airbag 10 in the default state. When the gas in the expansion airbag 10 expands due to heat, the diaphragm is pushed open under the action of air pressure. Heat conducting plates 12 are fixedly arranged at both bottom ends of the sound insulation door body 2, and the heat conducting plates 12 are attached to the outer side wall of the expansion airbag 10. The heat conducting plates 12 can play a role in heat conduction. The inside of the expansion airbag 10 is filled with a gas such as butane that expands rapidly when heated, so as to quickly push up the active baffle 6 when a fire breaks out.
[0025] And, a connecting block 13 is fixedly arranged at the top end of the active baffle 6. A limiting block 14 is fixedly arranged at the top end of the connecting block 13. Both sides of the limiting block 14 are arranged as inclined structures. The arrangement of the inclined structures enables the limiting block 14 to squeeze the positioning block 17, so as to facilitate the cooperation between the two to lock the position of the active baffle 6.
[0026] Moreover, a slot 15 is opened at the top end of the fixed frame 5. Limiting grooves 16 are opened on both sides of the slot 15. A positioning block 17 is arranged inside the limiting grooves 16. The positioning block 17 is arranged in an "L" - shaped structure and corresponds to the limiting block 14. A spring 18 is arranged between the positioning block 17 and the inner side wall of the limiting groove 16. A sliding block 19 is fixedly arranged at the top end of the positioning block 17, and the sliding block 19 is arranged above the fixed frame 5. The arrangement of the sliding block 19 can play an auxiliary positioning role for the positioning block 17 to prevent the positioning block 17 from moving downward under the influence of the limiting block 14. A sealing frame 20 is fixedly arranged at the top end of the fixed frame 5, and the sealing frame 20 is arranged outside the sliding block 19. The sealing frame 20 can play an auxiliary sealing role for the fixed frame 5.
[0027] Meanwhile, a plurality of anchor rods 21 are arranged around the outer side wall of the door frame 1. The arrangement of the anchor rods 21 facilitates the installation and fixation of the door frame 1. A handle 22 is fixedly arranged in the middle of the outer side wall of the sound insulation door body 2. The arrangement of the handle 22 facilitates the opening and closing of the sound insulation door body 2.
[0028] The working principle of the present utility model:
[0029] When the device is in use, the door frame 1 is fixed at a specified position through the anchor rod 21, and the sound-insulating door body 2 cooperates with the door frame 1 to form a fireproof door structure. In case of a fire, the heat conducting plate 12 transmits the high temperature generated by the fire to the expansion airbag 10, causing the gas inside the expansion airbag 10 to expand rapidly. The expanded gas flushes open the diaphragm in the connecting pipe 11. At this time, the expanded gas enters the air guide cavity 7 through the air guide pipe 9 and pushes the piston 8 in the air guide cavity 7, causing the piston 8 to move upward. The piston 8 drives the movable baffle 6 to move upward rapidly until the movable baffle 6 moves to the position of the observation window 4. At this time, the limiting block 14 at the top of the movable baffle 6 presses the positioning block 17, and the positioning block 17 slides horizontally under the extrusion until the limiting block 14 moves above the positioning block 17. Then the positioning block 17 resets under the action of the spring 18. At this time, the positioning block 17 fixes the position of the limiting block 14, thereby fixing the movable baffle 6 at the position of the observation window 4 to achieve the sealing of the observation window 4. At this time, the sound-insulating door body 2 and the door frame 1 can achieve the sealing of the fire chamber.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
