Description

Technical Field

[0001] This invention relates to the field of ship structural ventilation duct technology, and in particular to a ship flange-type structural ventilation duct. Background Technology

[0002] Structural air ducts typically rely on the ship's hull structure, consisting of multiple cofferdams welded to the hull structure to form a closed, box-like space. Openings in the cofferdams along the airflow direction connect to air ducts, creating pathways. The connection between the air ducts and the structural air ducts is usually a short pipe welded to the structural air duct, allowing air to flow from the structural air duct into the air duct. The "I"-shaped hull pillar is a common hull structure in ships. In structural air ducts relying on these "I"-shaped hull pillars, the portion of the pillar extending beyond the structural air duct affects the welding between the air duct and the structural air duct. Summary of the Invention

[0003] In view of the problem that existing air ducts cannot be welded to structural air ducts that rely on the "I"-shaped hull columns, this invention provides a ship flange-type structural air duct.

[0004] This invention provides a ship flange-type ventilation duct, comprising:

[0005] I-shaped hull pillars;

[0006] Side panels are provided on the side of the I-shaped hull column and enclose the I-shaped hull column to form a box structure. At least a portion of the two parallel plates on the I-shaped hull column extends out of the box structure.

[0007] A bottom panel is provided at the bottom of the box structure;

[0008] A top panel is provided on the top of the box structure;

[0009] The air duct is located outside the side panel on the side where the I-shaped hull column is located. The opening of the air duct is opposite to the side panel on the side where the I-shaped hull column is located, and the air duct has a plate-shaped pipe wall that corresponds to the plate surface on the I-shaped hull column near the middle of the side panel.

[0010] The first extended enclosure is provided on the side panel of the I-shaped hull column, corresponding to the other part of the tank wall of the air duct excluding the plate-shaped part. The plate surface of the I-shaped hull column near the middle of the side panel is provided with a second extended enclosure that can be enclosed with the first extended enclosure to form a shape and structure adapted to the air duct. The first extended enclosure and the second extended enclosure are provided with a first flange on the side facing the air duct, and are connected to a second flange provided at the end of the air duct through the first flange. The air duct and the box structure are connected by opening an opening in the side panel inside the shape enclosed by the first extended enclosure and the second extended enclosure.

[0011] In some embodiments of the present invention, the air duct is rectangular, and the first extended cofferdam and the second extended cofferdam provided on the plate surface near the middle of the side cofferdam on the I-shaped hull column enclose each other to form a rectangular structure adapted to the air duct.

[0012] In some embodiments of the present invention, the first extended enclosure includes three extended sub-enclosures, and each extended sub-enclosure is flush with the second extended enclosure. The external dimensions of the structure formed by the first extended enclosure and the second extended enclosure are the same as the external dimensions of the air duct.

[0013] In some embodiments of the present invention, the second extended cofferdam is provided in an extended arc shape at the end where it connects with the plate surface on the I-shaped hull column.

[0014] In some embodiments of the present invention, the first flange and the second flange are fixed together by bolts.

[0015] In some embodiments of the present invention, both the first flange and the second flange are angle steel flanges.

[0016] Compared with the prior art, the beneficial effects of the ship flange-type structure air duct provided in the embodiments of the present invention are as follows: the flange-type structure air duct design, including the panel of the "I"-shaped hull column, can solve the problem that the air duct cannot be welded due to the reliance on the "I"-shaped hull column; and the air duct design is simple, practical, and convenient for air duct disassembly.

[0034] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0035] This invention provides a flange-type air duct structure for ships, such as... Figures 1 to 8 As shown, it includes:

[0036] I-shaped hull pillars;

[0037] Side panels are provided on the side of the I-shaped hull column and enclose the I-shaped hull column to form a box structure. At least a portion of the two parallel plates on the I-shaped hull column extends out of the box structure.

[0038] A bottom panel is provided at the bottom of the box structure;

[0039] A top panel is provided on the top of the box structure;

[0040] The air duct is located outside the side panel on the side where the I-shaped hull column is located. The opening of the air duct is opposite to the side panel on the side where the I-shaped hull column is located, and the air duct has a plate-shaped pipe wall that corresponds to the plate surface on the I-shaped hull column near the middle of the side panel.

[0041] The first extended enclosure is provided on the side panel of the I-shaped hull column, corresponding to the other part of the tank wall of the air duct excluding the plate-shaped part. The plate surface of the I-shaped hull column near the middle of the side panel is provided with a second extended enclosure that can be enclosed with the first extended enclosure to form a shape and structure adapted to the air duct. The first extended enclosure and the second extended enclosure are provided with a first flange on the side facing the air duct, and are connected to a second flange provided at the end of the air duct through the first flange. The air duct and the box structure are connected by opening an opening in the side panel inside the shape enclosed by the first extended enclosure and the second extended enclosure.

[0042] In some embodiments of the present invention, the air duct is rectangular, and the first extended cofferdam and the second extended cofferdam provided on the plate surface near the middle of the side cofferdam on the I-shaped hull column enclose each other to form a rectangular structure adapted to the air duct.

[0043] In some embodiments of the present invention, the first extended enclosure includes three extended sub-enclosures, and each extended sub-enclosure is flush with the second extended enclosure. The external dimensions of the structure formed by the first extended enclosure and the second extended enclosure are the same as the external dimensions of the air duct.

[0044] In some embodiments of the present invention, the second extended cofferdam is provided in an extended arc shape at the end where it connects with the plate surface on the I-shaped hull column.

[0045] In this embodiment, the first flange and the second flange are fixed together by bolts, and both the first flange and the second flange are angle steel flanges.

[0046] To facilitate understanding of the above technical solutions, a specific example is provided below:

[0047] The aforementioned ship flange-type structure ventilation duct may include a structure ventilation duct relying on the "I"-shaped hull columns, angle steel flanges, and cofferdams;

[0048] The structural air duct, relying on the "I"-shaped hull pillars, is a box-like space formed by welding side cofferdams, bottom cofferdams, and top cofferdams to the "I"-shaped hull pillars. After the air ducts are welded to the structural air duct, air flows through openings in the side cofferdams.

[0049] When constructing the structural air duct, the "I"-shaped hull pillars protrude beyond the ductwork. However, the four sides of the duct are flush. During welding, the unevenness of the protruding structural air duct prevents proper welding. Figure 1 and 2 As shown;

[0050] Since the structural air duct protrudes only on one side, three side panels are welded to the location where the air duct will be installed. These panels are flush with the protruding part, and their outer diameter matches that of the air duct. An opening is made in the side panel to allow for airflow. Figure 3 and 4 As shown;

[0051] At this point, the connection between structural ducts can only be achieved by butt welding. The welding area is small, the weld is not strong, and the duct cannot be disassembled after welding, which will affect the maintenance inside the structural duct.

[0052] Therefore, the length of the three first extension panels was extended, and the panel of the "I"-shaped hull column was also partially extended at the section where the air duct was installed. A second extension panel was then installed, making the panel flush with the first extension panel. The purpose was to install flanges on the extended panels, allowing the structural air ducts and air pipes to be bolted together via the flanges. Figure 5 and 6 As shown;

[0053] The "I"-shaped hull pillars serve to support the hull structure. To prevent stress concentration and fracture, the panels and extended sections of the "I"-shaped hull pillars are made into arc shapes, such as... Figure 7 and 8 As shown.

[0054] As can be seen from the above technical solutions, the ship flange-type air duct provided in the above embodiments of the present invention adopts a flange-type air duct design, including the panel of the "I"-shaped ship hull column, which can solve the problem that the air duct cannot be welded due to the reliance on the "I"-shaped ship hull column; moreover, the air duct design is simple, practical, and convenient for air duct disassembly.

[0055] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
