In current designs, air ducts are often arranged in the transverse bulkhead space, connected to the open deck fans and extended downward. Ventilation holes are opened or ventilation branches are installed at the loading position of each layer to achieve the ventilation purpose.

[0003] The current design of using transverse bulkhead space to arrange air ducts to achieve ventilation in the cargo hold has the following defects:

[0004] 1.

DETAILED DESCRIPTION

[0041] The following description is intended to fully illustrate the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0042] See also Figure 1-2 The utility model provides a technical solution: a ventilation structure for a container ship cargo hold, comprising:

[0043] The container ship 100 includes a bottom deck 101, a deck 102, and a cargo hold 103 disposed between the bottom deck 101 and the deck 102. The cargo hold 103 is provided with multiple rows of refrigerated containers 105 with compressors 1051. The refrigerated containers 105 in each row are arranged along the width direction of the container ship 100 and are stacked in the vertical direction. A platform 104 is provided between two adjacent refrigerated containers 105 in the vertical direction. A working area is reserved between two adjacent rows of refrigerated containers 105 in the length direction of the container ship 100. The ventilation structure 200 is located in the working area and is no higher than the lowest platform 104. A personnel passage 203 is provided in the ventilation structure 200. The personnel passage 203 is connected to the platform 104 in the vertical direction and passes through each refrigerated container 105 in the width direction of the container ship 100.

[0044] The ventilation structure 200 includes:

[0045] A ventilation member 201 is provided with a smooth inner wall and a transverse air duct 2011 formed by the inner wall. The transverse air duct 2011 is arranged along the transverse direction of the container ship 100. The ventilation member 201 is provided with an air inlet 2012 and an air outlet 2013 that communicate with the inside and outside of the transverse air duct 2011. The air outlet 2013 is connected to the working area.

[0046] The support member 202 is supported and connected between the cargo hold 103 and the outer wall of the ventilation member 201.

[0047] The ventilation structure 200 is provided with a transverse air duct 2011 and an air inlet 2012 and an air outlet 2013 connecting the inside and outside of the transverse air duct 2011. Air can enter through the air inlet 2012 and reach the working area through the air outlet 2013, thereby realizing air flow within the working area and meeting the ventilation requirements of the refrigerated container 105. The ventilation member 201 is supported by an external support member 202 to ensure its own strength and rigidity. The inner wall of the ventilation member 201 is smooth and has no structure, which does not increase the resistance of the transverse air duct 2011 during the ventilation process, thereby improving ventilation efficiency.

[0048] The ventilation structure 200 is arranged in the working area and is not higher than the lowest platform 104, and does not occupy additional space on the transverse bulkhead. This can reduce the number of air ducts arranged within the transverse bulkhead range, thereby reducing the number of structural parts, reducing the weight of the hull, and reducing the construction workload;

[0049] The ventilation structure 200 is provided with a personnel passage 203 which can connect the platforms 104 in the vertical direction and pass through the refrigerated containers 105 in the width direction of the container ship 100 without affecting the passage of personnel in the working area.

[0050] In one embodiment, the container ship 100 is an open container ship 100. It should be noted that the length direction of the container ship 100 refers to the shortest connecting line between the bow and stern of the container ship 100, the width direction of the container ship 100 refers to the shortest connecting direction between the sides of the container ship 100, and the vertical direction of the container ship 100 refers to the direction perpendicular to the bottom plate 101 of the container ship 100.

[0051] Continue to see Figure 1 Regarding the specific structure of the air duct on the ventilation structure 200, the ventilation structure 200 further includes:

[0052] An air source 204 is connected to the deck 102 and communicates with the transverse air duct 2011 via a main air duct 205. One end of the main air duct 205 is connected to the output end of the air source 204, and the other end of the main air duct 205 is connected to the air inlet 2012. The main air duct 205 is arranged vertically. In one embodiment of the present invention, the air source 204 is a fan. The output end of the fan and the air inlet 2012 are connected by an air supply duct. The inner wall of the air supply duct forms the main air duct 205. During use, the air source 204 injects air into the transverse air duct 2011 through the main air duct 205.

[0053] Furthermore, the transverse air duct 2011 includes a ventilation portion 2011a and an air inlet portion 2011b connected in sequence along the length direction. The ventilation portion 2011a is provided with the air outlet 2013, and the air inlet portion 2011b is provided with the air inlet 2012. The radial cross-sectional dimensions of the air inlet portion 2011b are larger than the radial cross-sectional dimensions of the ventilation portion 2011a, and the radial cross-sectional dimensions of the ventilation portion 2011a are the same at any position in the axial direction. Furthermore, the cross-sectional dimensions of the air inlet portion 2011b gradually increase as it approaches the air inlet 2012, and the bottom surface of the air inlet portion 2011b is lower than the bottom surface of the ventilation portion 2011a. Through the above design, the partially enlarged air inlet 2011b can realize that when the wind source 204 supplies air through the main air duct 205, the airflow in the main air duct 205 and the airflow in the transverse air duct 2011 can be smoothly turned inside the air inlet 2011b, and the airflow in the main air duct 205 returns and rises when it contacts the bottom surface of the ventilation part 2011a and smoothly enters the ventilation part 2011a.

[0054] The air inlet 2012 is opened at the upper end of the air inlet portion 2011b. The ventilation portion 2011a is connected to one side of the air inlet portion 2011b in the width direction of the container ship 100. The side of the air inlet portion 2011b opposite to the ventilation portion 2011a is an inlet guide surface 2011b1. The extension line of the main air duct 205 in the length direction intersects with the inlet guide surface 2011b1. The height of the inlet guide surface 2011b1 gradually increases in a manner away from the bottom surface of the air inlet portion 2011b.

[0055] The inner side of the air inlet portion 2011b is provided with an outlet guide surface 2011b2, which is connected between the bottom surface of the air inlet portion 2011b and the bottom surface of the ventilation portion 2011a. The outlet guide surface 2011b2 is inclined so that the upper edge of the outlet guide surface 2011b2 approaches the ventilation portion 2011a. Through the above design, the cross-section of the air inlet portion 2011b is formed into a substantially funnel-shaped shape. The airflow entering the air inlet portion 2011b through the upper main air duct 205 converges at the bottom of the air inlet portion 2011b and enters the ventilation portion 2011a. The airflow entering through the air inlet 2012 contacts the outlet guide surface 2011b1, and the airflow flows toward the ventilation portion 2011a under the action of the inclined outlet guide surface 2011b1. The outlet guide surface 2011b2 guides the airflow, ensuring that the airflow flows smoothly through the air inlet portion 2011b into the ventilation portion 2011a.

[0056] Furthermore, the air outlets 2013 are sequentially spaced apart along the length of the transverse air duct 2011. Preferably, the distances between adjacent air outlets 2013 are equal, so that the airflow in the transverse air duct 2011 can fully drive the air flow in the working area through the air outlets 2013 during use.

[0057] Furthermore, the air outlet 2013 includes a flow air outlet 20131 and a heat dissipation air outlet 20132. The flow air outlet 20131 is located on at least one side of the ventilation member 201 in the vertical direction, and the heat dissipation air outlet 20132 is located on at least one side of the ventilation member 201 in the length direction of the container ship 100. The refrigerated container 105 is provided with a compressor 1051, and the heat dissipation air outlet 20132 is arranged toward the compressor 1051. The air outlet 2013 and the heat dissipation air outlet 20132 are both arranged at intervals along the length direction of the transverse air duct 2011. In the same radial plane of the transverse air duct 2011, the air outlet 2013 and the heat dissipation air outlet 20132 correspond one to one. In one embodiment of the present invention, the flow air outlet 20131 is located on the upper end surface of the ventilation member 201, and the heat dissipation air outlet 20132 is located on one side of the ventilation member 201 in the length direction of the container ship 100. Preferably, the size of the flow vents 20131 is larger than that of the blowing vents. When in use, the airflow in the transverse duct 2011 blows air through the heat dissipation vents 20132 to the compressor 1051 of the bottommost refrigerated container 105. The gas in the transverse duct 2011 is connected to the external environment through the flow vents 20131 to form air flow, thereby dissipating heat from the refrigerated containers 105 on each layer.

[0058] See also Figure 3 Furthermore, the ventilation member 201 is provided with a water hole 2014 that connects the inside and outside of the transverse air duct 2011. The water hole 2014 is located on the bottom surface of the transverse air duct 2011. Preferably, the water hole 2014 is located on the bottom surface of the air inlet portion 2011b. By providing the water hole 2014 at the lowest end of the bottom deck 101 of the transverse air duct 2011, accumulated water in the transverse air duct 2011, such as condensed water, rainwater, and water from waves, can flow out through the water hole 2014, ensuring ventilation and drying in the transverse air duct 2011 and preventing corrosion inside the transverse air duct 2011. Furthermore, the size of the water hole 2014 is much smaller than that of the air outlet 2013, thereby preventing the size of the water hole 2014 from adversely affecting the ventilation effect.

[0059] Furthermore, the ventilation structure 200 is supported and connected between two opposing transverse bulkheads within the cargo hold 103. Specifically, the longitudinal ends of the support member 202 are connected to one of the opposing transverse bulkheads within the cargo hold 103, and the longitudinal ends of the ventilation member 201 are connected to one of the opposing transverse bulkheads within the cargo hold 103. The box-shaped duct as a whole serves as a transverse support structure, contributing to the transverse strength of the ship. Its inherent strength and rigidity are ensured by the support member 202 disposed outside the ventilation member 201.

[0060] See also Figure 2 Furthermore, the support member 202 is connected between the bottom deck 101 and the lower end surface of the ventilation member 201, and the upper end surface of the ventilation member 201 is flush with the lowest platform 104. This ensures that the ventilation structure 200 occupies a small vertical working area while facilitating maintenance personnel to access the lowest platform 104 by ascending to the upper end surface of the ventilation member 201.

[0061] See also Figure 1 and 4 Regarding the specific structure of the personnel passage 203, it includes a interconnected transverse passage 203a, a longitudinal passage 203b, and a vertical passage 203c. Both the transverse passage 203a and the longitudinal passage 203b are provided on the support member 202. The transverse passage 203a connects the two sides of the container ship 100 in the width direction, the longitudinal passage 203b connects the two sides of the container ship 100 in the length direction, and the vertical passage 203c is provided between the support member 202 and the ventilation member 201. The transverse passage 203a and the longitudinal passage 203b for personnel passage provided on the support member 202 between the bottom surface of the ventilation member 201 and the bottom deck 101 ensure smooth passage between the refrigerated containers 105 on that layer. Furthermore, personnel can move between the platforms 104 on each layer within the work area through the vertical passage 203c.

[0062] Preferably, the bottom surface of the transverse channel 203a, the bottom surface of the longitudinal channel 203b, and the bottom surface of the vertical channel 203c are all flush with the upper end surface of the bottom deck 101 of the ship.

[0063] More specifically, there are multiple support members 202 , which are sequentially spaced apart along the length direction of the ventilation member 201 , and each support member 202 is provided with a transverse through hole 2021 that is connected to the ventilation member 201 in the length direction;

[0064] The ventilation member 201 is provided with vertical through holes 2015 in the vertical direction. The vertical through holes 2015 are arranged in a manner to avoid the transverse air duct 2011. The vertical through holes 2015 are arranged relative to the intervals between two adjacent support members 202.

[0065] The longitudinal channel 203b is formed between the opposite side surfaces of the adjacent support members 202, the inner wall of the transverse through hole 2021 forms the transverse channel 203a, and the inner wall of the vertical through hole 2015 forms the vertical channel 203c.

[0066] Preferably, the vertical passages 203c are arranged close to the center of the container ship 100 in the width direction, and the maximum distance between adjacent longitudinal passages 203b is not less than the size of the refrigerated container 105 in the width direction of the container ship 100.

[0067] To facilitate the passage of personnel and prevent the personnel passage 203 from affecting the air flow in the transverse air duct 2011, further, the number of the transverse air ducts 2011 is multiple, and the multiple transverse air ducts 2011 are arranged at intervals in the width direction of the container ship 100. The ends of adjacent transverse air ducts 2011 in the width direction of the container ship 100 are separated by middle side plates, and a vertical channel 203c is provided between two adjacent transverse air ducts 2011. In one embodiment, the number of the transverse air ducts 2011 is two, wherein the interval between the two transverse air ducts 2011 corresponds to the center position in the width direction of the container ship 100. Figure 1 The middle side panel at the center of the ship's width divides the transverse air duct 2011 into two independent left and right parts, and vertical through holes 2015 are opened in the middle area of ​​adjacent side panels to enable vertical passage of personnel to reach the various platforms 104 in the cargo hold.
