[0001] This utility model belongs to the field of marine ventilation technology, and specifically relates to a side ventilation device for automobile transport vessels. Background Technology
[0002] In areas such as cabins and engine rooms on ships, personnel and equipment require a suitable air environment. Therefore, in order to ensure air circulation and regulate temperature and humidity in the ship's interior space, cabin ventilation is required by regulations, and the ventilation terminals are located in open areas.
[0003] Ventilation systems typically consist of ventilation caps, fans, ventilation ducts, and valves. Car carriers have multiple, spacious decks, generally 5 to 14 decks, each a closed vehicle compartment. Therefore, ventilation caps are usually located on the top open deck. Due to the characteristics of this ship type, the high open deck necessitates longer ventilation ducts, increasing ventilation resistance. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a side ventilation device for automobile transport vessels, which can effectively reduce ventilation ducts and thus lower ventilation resistance.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A side ventilation device for a car transport vessel includes a ventilation buffer box and a ventilation duct. A bulkhead opening is provided on the outer side panel of the cabin. The ventilation buffer box is located inside the bulkhead opening and communicates with the outside of the cabin through the bulkhead opening. A louver parallel to the outer side panel of the cabin is provided inside the ventilation buffer box near the bulkhead opening. The ventilation duct passes through the bottom plate of the ventilation buffer box and communicates with the ventilation buffer box.
[0007] Furthermore, one side of the ventilation buffer box is a completely open structure, and the open side of the ventilation buffer box is positioned opposite to the opening in the bulkhead. The side wall of the open side of the ventilation buffer box extends into the opening in the bulkhead and is fixedly connected to the inner side wall of the opening in the bulkhead.
[0008] Furthermore, the four sides of the louvers are detachably connected to the inner wall of the ventilation buffer box.
[0009] Furthermore, multiple connecting blocks perpendicular to the inner wall of the ventilation buffer box are provided on the inner side wall of the ventilation buffer box. The multiple connecting blocks are distributed in a square matrix on a longitudinal section of the ventilation buffer box parallel to the opening of the cabin wall. The four sides of the louver are connected by bolts and anti-loosening nuts passing through the connecting blocks.
[0010] Furthermore, there are four connecting blocks, which are located on the upper and lower inner walls and the left and right inner walls of the ventilation buffer box, respectively; the connecting blocks are located on the side of the louver away from the opening in the cabin wall.
[0011] Furthermore, a protective net is provided between the connecting block and the louver, and the bolt passes through the protective net.
[0012] Furthermore, the bottom wall of the ventilation buffer box is inclined upward near the open end, and the angle between the bottom wall and the top wall of the ventilation buffer box is not less than 3°.
[0013] Furthermore, the upper part of the ventilation duct extends into the ventilation buffer box, and the minimum distance between the upper end face of the ventilation duct and the bottom wall of the ventilation buffer box is not less than 50mm.
[0014] Furthermore, the protective mesh is made of stainless steel wire mesh.
[0015] Furthermore, the outer side of the top wall of the ventilation buffer box is provided with lifting lugs.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] like Figures 1-3As shown, a side ventilation device for a car transport vessel includes a ventilation buffer box 1 and a ventilation duct 4. A bulkhead opening is provided on the outer side panel of the cabin. The ventilation buffer box 1 is located inside the bulkhead opening and communicates with the outside of the cabin through the bulkhead opening. A louver 2 parallel to the outer side panel of the cabin is provided inside the ventilation buffer box 1 near the bulkhead opening. The ventilation duct 4 passes through the bottom plate of the ventilation buffer box 1 and communicates with the ventilation buffer box 1.
[0023] Understandably, by installing ventilation buffer boxes 1 and ventilation ducts 4 inside each cabin, the length of the original ventilation ducts 4 is reduced, thus lowering the ventilation resistance.
[0024] Furthermore, one side of the ventilation buffer box 1 is a completely open structure, and the open side of the ventilation buffer box 1 is arranged opposite to the opening of the bulkhead. The side wall of the open side of the ventilation buffer box 1 extends into the opening of the bulkhead and is fixedly connected to the inner side wall of the opening of the bulkhead.
[0025] It is understandable that setting the ventilation side of the ventilation buffer box 1 as a fully open structure can increase the ventilation area; the side wall of the ventilation buffer box 1 extending into the opening of the bulkhead can increase the firmness of the connection between the ventilation buffer box 1 and the bulkhead.
[0026] The size of the louver 2 needs to be calculated based on the cabin ventilation requirements, and then a ventilation buffer box 1 of appropriate size is made according to the size of the louver 2 and the position of the ventilation duct 4.
[0027] Furthermore, the four sides of the louver 2 are detachably connected to the inner wall of the ventilation buffer box 1.
[0028] Specifically, multiple connecting blocks 3 perpendicular to the inner wall of the ventilation buffer box 1 are provided on the inner sidewall of the ventilation buffer box 1. These connecting blocks 3 are arranged in a square matrix on a longitudinal section of the ventilation buffer box 1 parallel to the opening in the bulkhead. The louvers 2 are connected around their perimeter by bolts and anti-loosening nuts 5 passing through the connecting blocks 3. Of course, in other embodiments, the louvers 2 can also be connected to the ventilation buffer box 1 using other alternative structural forms.
[0029] It is understandable that the louvers 2 are designed to be detachably connected to the ventilation buffer box 1 for easy replacement. The connecting block 3 should be as small as possible so that seawater and rainwater entering the ventilation buffer box 1 can flow out from both sides of the connecting block 3.
[0030] Furthermore, there are four connecting blocks 3. The positions of the four connecting blocks 3 can be any position in the above square matrix. However, in order to ensure the connection stability of the louver 2, the four connecting blocks 3 are respectively located on the upper and lower inner sidewalls and the left and right inner sidewalls of the ventilation buffer box 1. The connecting blocks 3 are located on the side of the louver 2 away from the opening in the cabin wall.
[0031] Furthermore, two connecting blocks 3 located on the upper and lower side walls of the ventilation buffer box 1 are arranged opposite each other, and two connecting blocks 3 located on the left and right side walls of the ventilation buffer box 1 are arranged opposite each other.
[0032] Furthermore, a protective net is provided between the connecting block 3 and the louver 2, and the bolt passes through the protective net.
[0033] Understandably, the protective netting is intended to prevent debris, birds, and other objects from entering the ventilation system. In some embodiments, the protective netting is stainless steel wire mesh 6.
[0034] Furthermore, the bottom wall of the ventilation buffer box 1 is inclined upward near the open end, and the angle between the bottom wall and the top wall of the ventilation buffer box 1 is not less than 3°; the upper part of the ventilation duct 4 extends into the ventilation buffer box 1, and the minimum distance between the upper end face of the ventilation duct 4 and the bottom wall of the ventilation buffer box 1 is not less than 50mm.
[0035] It is understandable that the bottom wall of the ventilation buffer box 1 is set at an angle to prevent seawater and rainwater from entering the ventilation duct 4. In order to prevent seawater and rainwater from flowing into the ventilation duct 4, the ventilation duct 4 must extend into the ventilation buffer box 1. In this way, as long as seawater and rainwater enter the ventilation buffer box 1, they will be discharged naturally.
[0036] Furthermore, the ventilation buffer box 1 is provided with lifting lugs 7 on the outer side of its top wall. This facilitates the hoisting and installation of the ventilation buffer box 1.
[0037] Those skilled in the art should understand that the above description is merely a specific embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
