In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0039] Figure 1 A cut structure schematic view of the auxiliary ventilation assembly for ship cabin provided by the present embodiment and the ship is shown. As shown in the figure, Figure 1 The present embodiment provides an auxiliary ventilation assembly for ship cabin, which is applied to a ship with a ship cabin 200. The ship cabin 200 can accommodate goods or passengers to realize passenger and cargo transportation of the ship. Whether the ship cabin 200 is used to transport goods or passengers, a corresponding ventilation assembly needs to be arranged to meet the circulating ventilation demand of the goods or passengers in the ship cabin 200.

[0040] It should be noted that in the existing technology, ventilation components usually include structural ducts arranged on both sides of the transport ship. The sides corresponding to the ship's lower deck are often linear, and the structural ducts need to bend synchronously with the hull line, resulting in high requirements for the processing precision of the structural ducts. In addition, for some ships with high ventilation requirements, the structural ducts on the sides are densely arranged, which seriously occupies space, makes construction difficult, and increases the weight of the entire ship.

[0041] To address the aforementioned problems, the auxiliary ventilation assembly for ship cabins provided in this embodiment includes a first support column 1 and a second support column 2. The first support column 1 has an internal cavity. One end of the first support column 1 is connected to the inner bottom wall of the ship cabin 200, and the other end of the first support column 1 passes through the deck 100 of the ship cabin 200 and extends to the outside of the ship cabin 200. The first support column 1 is fixedly connected to the deck 100. The portion of the first support column 1 located outside the ship cabin 200 has a first air inlet 11 communicating with its internal cavity. The portion of the first support column 1 located inside the ship cabin 200 has a first air inlet 11 communicating with its internal cavity. The first air outlet 12 is connected to both the cavity and the ship compartment 200; the second support column 2 has an internal cavity, one end of the second support column 2 is connected to the inner bottom wall of the ship compartment 200, the other end of the second support column 2 passes through the deck 100 of the ship compartment 200 and extends to the outside of the ship compartment 200, and the second support column 2 is fixedly connected to the deck 100. The part of the second support column 2 located outside the ship compartment 200 has a second air outlet 22 connected to its internal cavity, and the part of the second support column 2 located inside the ship compartment 200 has a second air inlet 21 connected to both its internal cavity and the ship compartment 200.

[0042] The auxiliary ventilation assembly for ship cabins provided in this embodiment supports the deck 100 by setting a first support column 1 and a second support column 2, both of which are connected to the inner bottom wall of the ship cabin 200 and the deck 100. By setting both the first support column 1 and the second support column 2 as internal cavity structures, and setting a first air inlet 11 and a first air outlet 12 on the first support column 1, and setting a second air inlet 21 and a second air outlet 22 on the second support column 2, fresh air from outside the ship cabin 200 can flow into the ship cabin 200 through the first support column 1, while stale air exhaled by passengers or odorous air emitted by cargo inside the ship cabin 200 can flow to the outside of the ship cabin 200 through the second support column 2, thereby meeting the circulating ventilation needs of cargo or passengers inside the ship cabin 200. Furthermore, by adopting the auxiliary ventilation components described above, the first support column 1 and the second support column 2 have the effect of both support and ventilation, which can reduce the number of structural air ducts on the side of the ship, thereby increasing the available space on the side of the ship. Moreover, the first support column 1 and the second support column 2 are both hollow structures, which can reduce the overall weight of the ship to a certain extent. Since the first support column 1 and the second support column 2 do not need to bend synchronously with the side line, the processing precision can be reduced and the processing cost can be reduced.

[0043] It should be noted that the auxiliary ventilation component for ship cabins provided in this embodiment is used in conjunction with the structural air ducts on the ship's side. The two are used together to achieve ventilation circulation within the ship cabin 200. However, due to the setting of this auxiliary ventilation component for ship cabins, the number of structural air ducts on the ship's side can be reduced, thus achieving the effect of increasing the available space on the ship's side and reducing the congestion on the ship's side.

[0044] Optionally, the deck 100 has a first through hole 101 through which the first support column 1 passes, and the first support column 1 passes through the first through hole 101 and is welded to the deck 100; the deck 100 also has a second through hole 102 through which the second support column 2 passes, and the second support column 2 passes through the second through hole 102 and is welded to the deck 100. Welded connections offer the advantages of secure connection and ease of operation. Of course, in other embodiments, any fixing method that enables the connection between the deck 100 and the first support column 1 or the second support column 2 is within the scope of protection of this application, and is not limited to welded connections between the first support column 1 and the deck 100 and welded connections between the second support column 2 and the deck 100, and will not be elaborated further here.

[0045] Figure 2 It shows Figure 1A partial sectional view at point AA. It is understandable that the deck 100 of the ship's compartment 200 is often fixed with mutually perpendicular strong transverse beams 301 and longitudinal girder 302 to improve the overall structural strength of the ship. However, if the first support column 1 and the second support column 2 supporting the deck 100 are installed to avoid the strong transverse beams 301 and longitudinal girder 302, the installation positions of the first support column 1 and the second support column 2 within the ship's compartment 200 will be greatly restricted, which is detrimental to the practical application of the first support column 1 and the second support column 2 on the ship. To solve this problem, such as... Figures 1 to 2 As shown, a strong crossbeam 301 and a longitudinal girder 302 are provided at both the first through hole 101 and the second through hole 102, and a through hole is provided at the junction of the strong crossbeam 301 and the longitudinal girder 302, directly opposite the first through hole 101 or the second through hole 102. When installing the first support column 1 and the second support column 2 on the ship, the first support column 1 can be passed through the corresponding through hole and the first through hole 101 in sequence, and the second support column 2 can be passed through the corresponding through hole and the second through hole 102. Then, the first support column 1 is welded to the deck 100, and the junction of the first support column 1 with the strong crossbeam 301 and the longitudinal girder 302 is welded. The second support column 2 is welded to the deck 100, and the junction of the second support column 2 with the strong crossbeam 301 and the longitudinal girder 302 is welded. This improves the adaptability of the auxiliary ventilation component for ship cabins provided in this embodiment for use on ships. Of course, strong crossbeams 301 and longitudinal girder 302 can also be installed at the location where the first support column 1 and the second support column 2 are not installed on the deck 100, but no perforations are made on the strong crossbeams 301 and longitudinal girder 302 installed at this location, so as to further ensure the structural strength of the deck 100.

[0046] If the first support column 1 passes through the perforation and the first through hole 101 in sequence, and the weld seam produced by welding the first support column 1 to the deck 100 is asymmetrical, or the weld seam produced by welding the first support column 1 to the perforation is asymmetrical, a high-stress zone is easily formed, and structural fatigue problems become prominent. Therefore, in this embodiment, the cross-section of the first support column 1 is a symmetrical structure. This design can effectively reduce the hot spot stress in the connection area between the first support column 1 and the deck 100, and reduce the risk of fatigue strength issues in the ship. Similarly, the cross-section of the second support column 2 is symmetrically arranged. This design can effectively reduce the hot spot stress in the connection area between the second support column 2 and the deck 100, and reduce the risk of fatigue strength issues in the ship. For example, the cross-section of the first support column 1 or the second support column 2 can be circular, rectangular, regular pentagonal, regular hexagonal, etc., so that the weld seam produced by welding each support column to the deck 100 is symmetrically arranged, effectively reducing the hot spot stress in the connection area between each support column and the deck 100. Of course, the shape of the cross section of the first support column 1 or the second support column 2 is not limited to the above example. As long as the welds produced by welding the first support column 1 and the second support column 2 to the deck 100 are symmetrically arranged, it will not be described in detail here.

[0047] like Figure 1 As shown, the number of ship compartments 200 is at least two, and the at least two ship compartments 200 are arranged vertically at intervals. One end of the first support column 1 and one end of the second support column 2 are both connected to the inner bottom wall of the ship compartment 200 located at the bottom. The other ends of the first support column 1 and the second support column 2 both pass through the deck 100 of the ship compartment 200 located at the top. The first support column 1 and the second support column 2 are fixedly connected to all decks 100. Each ship compartment 200 can independently carry cargo or passengers, thereby improving the ship's single-trip transport capacity. Exemplarily, there can be two, three, ten, etc., ship compartments 200. Designers can adjust the number of ship compartments 200 according to the ship's passenger and cargo transport capacity and the ship's size. This embodiment does not limit the specific number of ship compartments 200. In addition, by fixing the first support column 1 and the second support column 2 to all decks 100, the supporting effect of each support column on the deck 100 can be improved, thereby ensuring the stability of each ship compartment 200.

[0048] When the auxiliary ventilation component for ship cabins provided in this embodiment is applied to a ship, if only one first support column 1 and one second support column 2 are set to meet the circulating ventilation needs of all ship cabins 200 (i.e., the first support column 1 is provided with a first air outlet 12 corresponding to each ship cabin 200, and the second support column 2 is provided with a second air inlet 21 corresponding to each ship cabin 200), the fresh air entering from the first air inlet 11 of the first support column 1 will be distributed to each ship cabin 200 from top to bottom. The ship cabins 200 farther away from the first air inlet 11 of the first support column 1 will receive less fresh air. At the same time, the turbid gas or odor gas in the ship cabins 200 located below may drift through the second air inlet 21 of the second support column 2 to the ship cabins 200 located above it, thereby causing the circulating ventilation function of all ship cabins 200 to fail. To solve the above-mentioned technical problems, in this embodiment, each ship compartment 200 corresponds to at least one first support column 1 and one second support column 2. The first air outlet 12 on the first support column 1 is only connected to the ship compartment 200 corresponding to it, and the second air inlet 21 on the second support column 2 is only connected to the ship compartment 200 corresponding to it. Thus, each ship compartment 200 has at least one first support column 1 and one second support column 2 to provide ventilation circulation independently to meet the ventilation needs of each ship compartment 200. The first air outlet 12 and the first air inlet 11 are only connected to the ship compartment 200 corresponding to them, which can prevent turbid gas or odorous gas in the ship compartment 200 from drifting to adjacent ship compartments 200, and can also ensure that each ship compartment 200 has a sufficient amount of fresh air introduced. Of course, in other embodiments, each ship compartment 200 may be provided with three first support columns 1 and three second support columns 2, so as to circulate ventilation in the ship compartment 200 that requires enhanced circulation ventilation. The circulation ventilation requirements can be met by increasing the number of first support columns 1 and second support columns 2. The number of first support columns 1 and second support columns 2 is not fixed, as long as it can meet the ventilation requirements of each ship compartment 200. It will not be described in detail here.

[0049] To accelerate the air circulation efficiency inside and outside the ship's cabin 200, the auxiliary ventilation system for the ship's cabin also includes a first fan assembly 3. The first fan assembly 3 is connected to the first air inlet 11 and can draw fresh air from outside the ship's cabin 200 into the first air inlet 11. The fresh air then sequentially passes through the first air inlet 11, the inner cavity of the first support column 1, and the first air outlet 12 before entering the ship's cabin 200. Simultaneously, stale or odorous gases inside the ship's cabin 200 can sequentially pass through the second air inlet 21, the inner cavity of the second support column 2, and the second air outlet 22 before being discharged outside the ship's cabin 200. Specifically, the first fan assembly 3 includes a first fan 31, and the air outlet of the first fan 31 is connected to the first air inlet 11.

[0050] To further accelerate the air circulation efficiency inside and outside the ship's compartment 200, the auxiliary ventilation system for the ship's compartment also includes a second fan assembly 4, which is connected to the second air outlet 22. Specifically, the second fan assembly 4 includes a second fan 41, the air outlet of which is connected to the second air outlet 22.

[0051] When the auxiliary ventilation system for ship cabins is actually applied to a ship, the wind direction will inevitably change while the ship is sailing. If the vent of the first fan 31 faces downwind during ship movement, the fresh air outside the ship's cabin 200 will move in the same direction relative to the first fan 31, and the fresh air outside the cabin will move away from the vent of the first fan 31, which is not conducive to the first fan 31 drawing fresh air from outside the ship's cabin 200 into the cabin. Similarly, if the vent of the second fan 41 faces upwind during ship movement, the fresh air outside the cabin will move in the opposite direction relative to the second fan 41, and the fresh air outside the cabin will convect with the stale air or odors drawn from the cabin by the second fan 41, which is not conducive to the second fan 41 expelling the stale air or odors drawn from the ship's cabin 200 outside the cabin. Therefore, regardless of whether the ship is sailing with or against the wind, one of the first fan 31 and the second fan 41 will always be in a vent orientation that is unfavorable to the ventilation circulation of the ship's cabin 200. To solve the aforementioned technical problems, the air outlet of the first fan assembly 3 is oriented towards the width of the ship's cabin 200. This ensures that the airflow from fresh air outside the cabin does not affect the normal operation of the first fan 31, regardless of whether the ship is moving with the wind or against the wind. Similarly, the air outlet of the second fan assembly 4 is oriented towards the width of the ship's cabin 200. It is worth noting that by oriented the air outlets of both the first fan assembly 3 and the second fan assembly 4 towards the width of the ship's cabin 200, it can be ensured that the auxiliary ventilation components for the ship's cabins provided in this embodiment can meet the ventilation requirements of the ship's cabin 200 regardless of whether the ship is moving with the wind or against the wind.

[0052] In some embodiments, a first filter 32 is provided at the first air inlet 11 to prevent particulate matter carried in the fresh air outside the cabin from entering the cabin. A second filter 42 is provided at the second air outlet 22 to prevent particulate matter carried in the turbid gas or odor inside the cabin from entering the second fan 41 and affecting the service life of the second fan 41.

[0053] This embodiment also provides a ship in which the auxiliary ventilation component for ship cabins provided in this embodiment is applied, thereby enabling the air inside the ship cabin 200 to be exchanged with the air outside the ship cabin 200 through the auxiliary ventilation component for ship cabins, so as to meet the ventilation requirements of the ship cabin 200.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
