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

[0039] Figure 1 The schematic diagram of the cross-section structure of the auxiliary ventilation assembly for a ship cabin provided by this embodiment and the ship is shown. Figure 1 As shown, this embodiment provides an auxiliary ventilation assembly for a ship cabin, which is applied to a ship having a ship cabin 200. The ship cabin 200 can accommodate cargo or passengers to realize passenger and cargo transportation of the ship, and whether the ship cabin 200 is used to transport cargo or passengers, a corresponding ventilation assembly needs to be provided to meet the circulation ventilation requirements of the cargo or passengers in the ship cabin 200.

[0040] It should be noted that, in the prior art, ventilation components usually include structural air ducts arranged on both sides of the transport ship, and the side corresponding to the bottom cabin of the ship often has a linear shape. The structural air duct needs to bend synchronously with the hull line, resulting in high requirements on the processing accuracy of the structural air duct; in addition, for some ships with higher ventilation requirements, the structural air ducts on the side are densely arranged, the space is seriously squeezed, the construction is difficult, and the weight of the entire ship will be increased.

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

[0042] The auxiliary ventilation assembly for a ship cabin provided in this embodiment is provided with a first support column 1 and a second support column 2, and the first support column 1 and the second support column 2 are both connected to the inner bottom wall of the ship cabin 200 and the deck 100, so as to support the deck 100; by setting the first support column 1 and the second support column 2 as an inner cavity structure, 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 outside the ship cabin 200 can flow into the ship cabin 200 through the first support column 1, and at the same time, turbid gas exhaled by passengers in the ship cabin 200 or odorous gas emitted by cargo can flow to the outside of the ship cabin 200 through the second support column 2, thereby meeting the circulation ventilation needs of cargo or passengers in the ship cabin 200. Furthermore, by adopting the auxiliary ventilation assembly arranged as above, the first support column 1 and the second support column 2 have both supporting and ventilation effects, which can reduce the number of structural air ducts on the ship's side, thereby increasing the available space on the ship's side, and 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; because the first support column 1 and the second support column 2 do not need to bend synchronously with the side line, the processing accuracy can be reduced and the processing cost can be reduced.

[0043] It should be specially noted that the auxiliary ventilation assembly for the ship cabin provided in this embodiment is used together with the structural air duct on the side of the ship, and the two are used together to realize the ventilation circulation in the ship cabin 200. However, due to the setting of the auxiliary ventilation assembly for the ship cabin, the number of structural air ducts on the side of the ship can be reduced, thereby achieving the effect of increasing the available space on the side of the ship and reducing the congestion on the side of the ship.

[0044] Optionally, the deck 100 has a first through hole 101 for the first support column 1 to pass through, and the first support column 1 passes through the first through hole 101 and is welded to the deck 100; the deck 100 has a second through hole 102 for the second support column 2 to pass through, and the second support column 2 passes through the second through hole 102 and is welded to the deck 100. The welded connection has the advantages of being firmly connected and easy to operate. Of course, in other embodiments, as long as the fixing method that can achieve 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 the present application, it is not limited to the welding connection between the first support column 1 and the deck 100 and the welding connection between the second support column 2 and the deck 100, and will not be repeated here.

[0045] Figure 2 Shows Figure 1Partial cutaway view at AA in the figure. It is understandable that the deck 100 of the ship's cabin 200 is often fixed with mutually perpendicular strong beams 301 and longitudinal girders 302 to improve the overall structural strength of the ship. If the first support column 1 and the second support column 2 supporting the deck 100 are arranged to avoid the strong beam 301 and the longitudinal girders 302, the installation position of the first support column 1 and the second support column 2 in the ship's cabin 200 will inevitably be greatly restricted, which is not conducive to the practical application of the first support column 1 and the second support column 2 on the ship. To solve this problem, Figure 1 to Figure 2 As shown, the first through hole 101 and the second through hole 102 are both provided with a strong cross beam 301 and a longitudinal girder 302 connected vertically to each other, and the intersection of the strong cross beam 301 and the longitudinal girder 302 is provided with a through hole facing the first through hole 101 or the second through hole 102. When the first support column 1 and the second support column 2 are installed on the ship, the first support column 1 can be sequentially passed through the corresponding through hole and the first through hole 101, and the second support column 2 can be passed through the corresponding through hole and the second through hole 102, and then the first support column 1 is welded to the deck 100, and the first support column 1 is welded to the intersection of the strong cross beam 301 and the longitudinal girder 302, and the second support column 2 is welded to the deck 100, and the second support column 2 is welded to the intersection of the strong cross beam 301 and the longitudinal girder 302, thereby improving the adaptability of the auxiliary ventilation assembly for ship cabins provided by this embodiment in ships. Of course, a strong cross beam 301 and a longitudinal girder 302 may also be provided at a position on the deck 100 where the first support column 1 and the second support column 2 are not provided, but no perforations are provided on the strong cross beam 301 and the longitudinal girder 302 provided at this position 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, the weld seam generated by the welding of the first support column 1 and the deck 100 is asymmetric or the weld seam generated by the welding of the first support column 1 and the perforation is asymmetric, it is easy to form a high stress area, and the structural fatigue problem is 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 ship fatigue strength. Similarly, the cross section of the second support column 2 is symmetrically structured, and 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 ship fatigue strength. Exemplarily, 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 seams generated by the welding of each support column and the deck 100 are symmetrically arranged, effectively reducing the hot spot stress in the connection area between each support column and the deck 100. Of course, the cross-sectional shape 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, which will not be described in detail here.

[0047] like Figure 1 As shown, the number of ship cabins 200 is at least two, and at least two ship cabins 200 are arranged at intervals in the vertical direction. 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 cabin 200 located at the bottom layer, and the other end of the first support column 1 and the other end of the second support column 2 pass through the deck 100 of the ship cabin 200 located at the top layer, and the first support column 1 and the second support column 2 are fixedly connected to all decks 100. Each ship cabin 200 can carry cargo or passengers separately, thereby improving the single transportation capacity of the ship. For example, there can be two, three, ten, etc. ship cabins 200. The designer can adjust the number of ship cabins 200 according to the passenger and cargo transportation carrying capacity of the ship and the size of the ship. The specific number of ship cabins 200 is not limited in this embodiment. In addition, by fixing the first support column 1 and the second support column 2 to all decks 100, the support effect of each support column on the deck 100 can be improved to ensure the stability of each ship cabin 200.

[0048] When the auxiliary ventilation assembly for ship cabins provided in this embodiment is applied to ships, if only one first support column 1 and one second support column 2 are set to meet the circulation ventilation needs of all ship cabins 200 (that is, 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 diverted from top to bottom to each ship cabin 200. The farther the ship cabin 200 is from the first air inlet 11 of the first support column 1, the less fresh air will be distributed. At the same time, the turbid gas or odorous gas in the ship cabin 200 located below will likely float through the second air inlet 21 of the second support column 2 to the ship cabin 200 located above it, thereby causing the circulation ventilation function of all ship cabins 200 to fail. To solve the above technical problems, in the present embodiment, each ship cabin 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 corresponding ship cabin 200, and the second air inlet 21 on the second support column 2 is only connected to the corresponding ship cabin 200, so that each ship cabin 200 has at least one first support column 1 and a second support column 2 to provide ventilation circulation separately to meet the ventilation needs of each ship cabin 200, and the first air outlet 12 and the first air inlet 11 are only connected to the corresponding ship cabin 200, which can prevent the turbid gas or odorous gas in the ship cabin 200 from drifting to the adjacent ship cabin 200, and can ensure that each layer of the ship cabin 200 has sufficient fresh air introduced. Of course, in other embodiments, each ship cabin 200 may also correspond to three first support columns 1 and three second support columns 2, so as to perform ventilation circulation for the ship cabin 200 that needs enhanced circulation ventilation, and meet its circulation ventilation needs 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, and can meet the ventilation needs of each ship cabin 200, which will not be described one by one here.

[0049] In order to speed up the circulation efficiency of air inside and outside the ship cabin 200, the auxiliary ventilation assembly for the ship cabin also includes a first fan assembly 3, which is connected to the first air inlet 11, and can inhale fresh air outside the ship cabin 200 into the first air inlet 11, and then allow the fresh air outside the ship cabin 200 to enter the ship cabin 200 through the first air inlet 11, the inner cavity of the first support column 1 and the first air outlet 12 in sequence, and at the same time, the turbid gas or odorous gas in the ship cabin 200 can be discharged to the outside of the ship cabin 200 through the second air inlet 21, the inner cavity of the second support column 2 and the second air outlet 22 in sequence. 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] In order to further accelerate the circulation efficiency of air inside and outside the ship cabin 200, the auxiliary ventilation assembly for the ship cabin also includes a second fan assembly 4, and the second fan assembly 4 is connected to the second air outlet 22. Specifically, the second fan assembly 4 includes a second fan 41, and the air outlet of the second fan 41 is connected to the second air outlet 22.

[0051] When the auxiliary ventilation assembly for ship cabin is actually applied to a ship, if the ship is in motion, the wind direction is bound to be changeable. If the air outlet of the first fan 31 faces the downwind direction during the movement of the ship, the fresh air outside the ship cabin 200 will move in the same direction relative to the first fan 31, and the fresh air outside the cabin will be away from the air outlet of the first fan 31, which is not conducive to the first fan 31 introducing the fresh air outside the ship cabin 200 into the cabin; similarly, if the air outlet of the second fan 41 faces the upwind direction during the movement of the ship, 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 turbid gas or odor drawn from the cabin by the second fan 41, which is not conducive to the second fan 41 to discharge the turbid gas or odor drawn from the ship cabin 200 to the outside of the cabin. Therefore, no matter whether the ship is traveling with the wind or against the wind, one of the first fan 31 and the second fan 41 will always be in an air outlet direction that is not conducive to the ventilation cycle of the ship cabin 200. In order to solve the above technical problems, the air outlet of the first fan assembly 3 is arranged toward the width direction of the ship cabin 200, so that no matter whether the ship is in the process of moving with the wind or in the process of moving against the wind, the airflow generated by the fresh air outside the cabin will not affect the normal operation of the first fan 31. Similarly, the air outlet of the second fan assembly 4 is arranged toward the width direction of the ship cabin 200. It is worth noting that by setting the air outlets of the first fan assembly 3 and the second fan assembly 4 toward the width direction of the ship cabin 200, it can be ensured that no matter whether the ship is in the process of moving with the wind or in the process of moving against the wind, the auxiliary ventilation assembly for the ship cabin provided in this embodiment can meet the normal operation and meet the ventilation needs of the ship cabin 200.

[0052] In some embodiments, a first filter 32 is provided at the first air inlet 11 to prevent particles 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 particles carried in turbid gas or odor in the cabin from entering the second fan 41 and affecting the service life of the second fan 41.

[0053] The present embodiment also provides a ship. By applying the auxiliary ventilation assembly for the ship cabin provided by the present embodiment, the air in the ship cabin 200 can be exchanged with the air outside the ship cabin 200 through the auxiliary ventilation assembly for the ship cabin to meet the ventilation needs 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 embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
