Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fire doors, in particular to a structure of a silent fire door for a container. Background Technique
[0002] A container refers to a large loading container with a certain strength, stiffness and specifications for exclusive turnover use. Nowadays, containers are widely used, not only for transportation functions, but also widely used in temporary or permanent buildings, such as photovoltaic and energy storage power stations, power generation stations, substations, etc. If a container used as a power generation station or the like is close to a residential area, the noise generated during its operation may affect the daily life of residents. In addition, there is also a risk of spontaneous combustion caused by short circuits or high temperatures in power generation equipment or energy storage equipment, etc. In order to prevent the spread of fire to residential areas, it is also necessary to improve the fire protection requirements for containers. Most of the existing fire doors for containers are ordinary fire sliding doors. After being closed, the sliding door will be completely sealed with the container, and it is impossible to extinguish the fire inside the container.
[0003] Therefore, the utility model provides a structure of a silent fire door for a container. Content of the Utility Model

The utility model can achieve better fire protection and sound insulation effects through a double-door structure; it can also extinguish the fire inside the container through the first through groove and the second through groove.
[0005] In order to achieve the above purpose, the utility model is realized through the following technical solutions: A structure of a silent fire door for a container includes an outer door frame integrated with the container. An inner door frame is installed inside the outer door frame. A door body is hinged inside the inner door frame. A limiting block is installed inside the outer door frame, and the limiting block corresponds to the door body. A sliding door is slidably matched on one side of the outer door frame. There is a gap between the sliding door and the door body. A first through groove is opened inside the door body, and a second through groove is opened inside the sliding door. The first through groove corresponds to the second through groove.
[0006] Further, an embedded groove is opened inside the outer door frame, and the embedded groove corresponds to the inner door frame.
[0007] Further, a high-temperature resistant rubber sealing pad is fixed on the limiting block, and the high-temperature resistant rubber sealing pad contacts the door body.
[0008] Further, a plurality of hinges are installed between the inner door frame and the door body.
[0009] Further, a slide rail is fixed on the outer door frame, and the slide rail corresponds to the sliding door.
[0010] Further, a first observation port is provided on the door body, and a second observation port is provided on the sliding door. Glass plates are fixed in both the first observation port and the second observation port.
[0011] Further, a first plug is in threaded fit in the first through groove, and a second plug is fixedly clamped in the second through groove.
[0012] Further, a handle is fixed on the door body.
[0013] The beneficial effects of the present utility model: A container silent fireproof door structure of the present utility model includes an inner door frame; a door body; an outer door frame; a sliding door; a gap; a first through groove; a second through groove.
[0014] The door body is installed in the inner door frame, and the sliding door is installed on one side of the outer door frame. There is a gap between the sliding door and the door body. The double-door structure can achieve better fireproof and sound insulation effects. A first through groove is opened in the door body, and a second through groove is opened in the sliding door. The interior of the container can be extinguished through the first through groove and the second through groove. Description of the Drawings

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a structure of a container soundproof and fireproof door, including an outer door frame 1 integrated with the container. An inner door frame 2 is installed inside the outer door frame 1. A door body 4 is hinged inside the inner door frame 2. A limiting block 17 is installed inside the outer door frame 1, and the limiting block 17 corresponds to the door body 4. A sliding door 9 is slidably matched on one side of the outer door frame 1. There is a gap 14 between the sliding door 9 and the door body 4. A first through groove 10 is opened inside the door body 4, and a second through groove 11 is opened inside the sliding door 9. The first through groove 10 corresponds to the second through groove 11.
[0022] In this embodiment, an embedded groove 15 is opened inside the outer door frame 1, and the embedded groove 15 corresponds to the inner door frame 2. A high-temperature resistant rubber gasket 16 is fixed on the limiting block 17, and the high-temperature resistant rubber gasket 16 is in contact with the door body 4. A handle 5 is fixed on the door body 4. A plurality of hinges 3 are installed between the inner door frame 2 and the door body 4. A slide rail 8 is fixed on the outer door frame 1, and the slide rail 8 corresponds to the sliding door 9.
[0023] Specifically, when it is necessary to close the container door, slide the sliding door 9, and then push and pull the door body 4 through the handle 5, so that the door body 4 completely enters the inner door frame 2. At this time, a gap 14 can be generated between the sliding door 9 and the inner door frame 2. The door body 4 is in contact with the high-temperature resistant rubber gasket 16, which can achieve a better soundproof effect and can also achieve a better fireproof effect, preventing smoke from flowing out through the gap between the door body 4 and the inner door frame 2.
[0024] A first observation port 6 is opened on the door body 4, and a second observation port 7 is opened on the sliding door 9. Glass plates are fixed in both the first observation port 6 and the second observation port 7. A first plug 12 is in threaded fit inside the first through groove 10, and a second plug 13 is snap-fitted and fixed inside the second through groove 11.
[0025] Specifically, when it is necessary to extinguish a fire inside the container, the fire situation inside the container can be observed through the first observation port 6 and the second observation port 7. Then rotate and remove the first plug 12, insert the nozzle of the fire extinguisher into the first through groove 10, and then push the second plug 13 through the nozzle of the fire extinguisher, so that the second plug 13 can be pushed off, and thus the nozzle of the fire extinguisher can pass through the first through groove 10 and the second through groove 11 to extinguish the fire inside the container.
[0026] When the fire situation is relatively large, at this time, only remove the first plug 12, and then insert the nozzle of the fire extinguisher into the first through groove 10, so that the nozzle of the fire extinguisher enters the gap 14, and carbon dioxide can be filled into the gap 14, thus achieving a better fire isolation effect.
[0027] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and 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.
