[0018] The air duct structure inside the modular shelter provided by this utility model adopts a splicing method, which allows for flexible assembly, facilitates installation inside the shelter, improves assembly efficiency, and also facilitates subsequent maintenance. Furthermore, the air duct structure integrates better with the modular shelter, reducing the space occupied within the shelter. The following detailed description of this utility model is provided in conjunction with specific embodiments: In some embodiments, the present invention provides an internal air duct structure for a modular cabin, which is installed on the top wall of the cabin, such as... Figure 1 , Figure 2 As shown, the system includes a main duct body 1, a cover plate 2, and a connecting section 3. The main duct body 1 is connected to the top wall, the cover plate 2 is connected to the main duct body 1 to form a closed flow channel, and the connecting section 3 is used to connect two adjacent sections of the main duct body 1. The number of main duct bodies 1 can be determined according to the length, or the length of the main duct body 1 can be adjusted. Because the structure of the main duct body 1 is relatively simple, its size can be flexibly adjusted, making it easier to adapt to different container cabins.

[0019] like Figure 3 As shown, the main body 1 of the air duct includes a base plate 11 and two side plates 12. The two side plates 12 are parallel to each other and are respectively connected to the two sides of the base plate 11. The two side plates 12 are perpendicular to the base plate 11. Optionally, the base plate 11 is a rectangular plate, and the two side plates 12 are rectangular plates. The long side of the side plate 12 is the same length as the long side of the base plate 11, and one long side of the side plate 12 is connected to one long side of the base plate 11. Optionally, the base plate 11 and the two side plates 12 are integrally formed by bending, or the base plate 11 and the two side plates 12 are separately formed and then sealed and connected into one piece by welding, riveting, or other connection methods.

[0020] An edge 13 parallel to the bottom plate 11 is formed on the edge of the side plate 12 away from the bottom plate 11. The edge 13 is bent toward the other side plate 12 and is perpendicular to the side plate 12. A plurality of first connecting holes 131 are formed on the edge 13. Optionally, the first connecting holes 131 are threaded holes that can be used for screw installation, or the first connecting holes 131 are smooth holes that can be used for rivet installation.

[0021] In some embodiments, the side plate 12 is provided with a plurality of fixing holes 121 for fixing the air duct body 1. Optionally, the fixing holes 121 are open holes, which can be used with screws or rivets to connect the side plate 12 to the top wall.

[0022] In some embodiments, such as Figure 2 As shown, the cover plate 2 is a plate-like structure used to cover the air duct body 1 and is sealed to the two side plates 12. Optionally, the cover plate 2 is a flat plate with the same shape and size as the bottom plate 11 of the air duct body 1, and is sealed to the side plates 12 to form a rectangular cylindrical air duct with the air duct body 1. Optionally, multiple first through holes 21 are formed on both sides of the cover plate 2 near the long edge. The position and number of the first through holes 21 correspond to the first connecting holes 131, that is, each first through hole 21 corresponds to one first connecting hole 131. The cover plate 2 is connected to the folded edge 13 by a connector. For example, when the first connecting hole 131 is a threaded hole, the cover plate 2 is connected to the folded edge 13 by a screw. When the first connecting hole 131 is a smooth hole, the cover plate 2 is connected to the folded edge 13 by a rivet. Optionally, a sealing layer is provided between the cover plate 2 and the folded edge 13. For example, a sealing layer can be formed by sealant or gasket, so that a sealed connection is formed between the cover plate 2 and the folded edge 13, that is, between the cover plate 2 and the air duct body 1.

[0023] like Figure 2 , Figure 4 As shown, the connecting section 3 is a rectangular cylindrical structure used to be embedded into two adjacent air duct body 1 to connect the two air duct body 1. Optionally, a sealing layer is formed between the side wall of the connecting section 3 and the bottom wall and side wall of the air duct body 1. For example, a sealing layer can be formed by sealant to form a sealed connection between the connecting section 3 and the air duct body 1. Optionally, high-temperature resistant sealant can be applied to the outer wall of the connecting section 3 before it is inserted into the air duct body 1, so that the sealant forms a sealing layer between the connecting section 3 and the air duct body 1.

[0024] One panel of the connecting section 3 forms a connecting surface 31, which is the surface away from the bottom wall of the air duct body 1. A second connecting hole 311 is formed on the connecting surface 31. Optionally, the second connecting hole 311 is the same as the first connecting hole 131, and can be set as a threaded hole or a smooth hole at the same time as the first connecting hole 131. Correspondingly, the cover plate 2 is provided with a second through hole 22 corresponding to the second connecting hole 311. That is, the cover plate 2 is provided with a second through hole 22 near its short side edge. Each second through hole 22 corresponds to a second connecting hole 311. The cover plate 2 is connected to the second connecting hole 311 through a connector. Optionally, a sealing layer is formed between the connecting surface 31 and the cover plate 2. For example, a sealing layer can be formed by sealant or a sealing gasket to form a sealed connection between the cover plate 2 and the connecting surface 31 of the connecting section 3.

[0025] In some embodiments, such as Figure 5As shown, there are multiple air duct bodies 1, and each air duct body 1 is provided with a cover plate 2. Two adjacent air duct bodies 1 are sealed and connected to the same connecting section 3. Furthermore, two adjacent cover plates 2 are connected to the same connecting section 3, so that multiple air duct bodies 1 can be connected into one unit through the cover plate 2 and the connecting section 3.

[0026] In some embodiments, the present invention provides a modular shelter, such as... Figure 6 , Figure 7 As shown, the cabin includes a top wall consisting of a frame 4 and a skin. A perforated structure is formed on the frame 4, and the air duct structure inside the cabin is embedded in the perforated structure.

[0027] The frame 4 includes multiple sub-frames of the same size as the main body 1 of the duct. The main body 1 of the duct is embedded in the sub-frames, and the side plates 12 are connected to the sub-frames. Optionally, the frame 4 includes support rods 5 arranged along its length. The distance between the support rods 5 and the sides of the frame 4 is the same as the width of the main body 1 of the duct. The main body 1 of the duct can be embedded between the support rods 5 and the sides of the frame 4. A support plate 6 is arranged at certain intervals on the support rods 5. The support plate 6 is a long strip plate and is perpendicularly connected to the sides of the support rods 5 and the frame 4. The distance between two support plates 6 is the same as the length of the main body 1 of the duct. The connecting segment 3 can pass through the support plate 6 and be embedded in both main bodies 1 of the duct. The support plate 6 provides support for the connecting segment 3. Optionally, the fixing holes 121 on the side plates 12 of the main body 1 of the duct cooperate with the connectors to fix and connect with the support rods 5 and the side plates 12 of the frame 4, for example, by screws or rivets.

[0028] Optionally, the height of the side plate 12 of the air duct body 1 is the same as the height of the support rod 5, or the height of the side plate 12 is slightly less than the height of the support rod 5. After the cover plate 2 is connected to the air duct body 1, it is flush with the support rod 5. This can avoid the air duct structure occupying the internal space of the cabin, and will not affect the internal height of the cabin. It also makes the air duct structure and the top wall more integrated and more aesthetically pleasing.

[0029] Optionally, sealant can be applied to the skin before embedding the duct body 1 into the frame 4 and bonding it to the skin with sealant, which further secures the duct body 1. Furthermore, in this embodiment, multiple grooves are formed on the skin to improve its strength. In the corresponding area of ​​the sub-frame 4, foam board is filled into the grooves to create a flat surface in the area where the duct body 1 is installed. After applying sealant, the duct body 1 is installed to improve the reliability of the duct body 1 installation.

[0030] In some embodiments, two parallel air duct structures are provided on the top wall, with the two air duct structures located on two sides along the length of the top wall.
