AI Technical Summary
In container ships, the arrangement of vent pipes makes it difficult to drill holes in the high-strength crack-arresting steel upper deck, which affects the strength of the main deck.
The venting pipe arrangement chamber is located between the cargo hold transverse bulkhead and the hatch coaming. The venting pipe passes through the top plate of the cargo hold transverse bulkhead, and the outlet is located in the venting pipe arrangement chamber. The side wall is a watertight wall, and the water outlet is inclined upward to the upper deck. The lowest point of the water outlet is flush with the upper deck to avoid opening holes in the high-strength crack-arresting steel upper deck.
This reduced the difficulty of opening holes, ensured the strength of the main deck, and reduced the possibility of overflow water entering the cargo hold, thus maintaining a clean transportation environment inside the container ship.

[0024] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 , 2 As shown, the present application provides a vent pipe arrangement room 1 for a ballast water tank of a container ship, which is arranged between a cargo hold bulkhead and a hatch coaming 10, the bottom plate of the vent pipe arrangement room 1 is a cargo hold bulkhead top plate 11, the side walls of the vent pipe arrangement room 1 are all watertight walls 8, one of the side walls of the vent pipe arrangement room 1 is arranged at the junction of the cargo hold bulkhead and the upper deck 13, the vent pipes 2 of the container ship all pass through the bottom plate of the ballast water tank vent pipe arrangement room 1 of the container ship, the outlets of the vent pipes 2 are all arranged in the vent pipe arrangement room 1, and a water flow hole 9 is arranged below the side wall at the junction.
[0026] The bottom plate of the vent pipe arrangement room 1 has a slope inclined toward the water flow hole 9, and the water flow hole 9 has a slope inclined toward the upper deck 13. The lowest point of the water flow hole 9 is flush with the upper deck 13, so as to better retain the water overflowing from the vent pipe 2 to the upper deck. Figure 1As shown, in this embodiment, the top plate of the ventilation pipe arrangement room 1 is a hatch coaming 10. In order to facilitate the entry and exit of the staff and the lifting of components, an inlet and outlet 5 is provided on the top plate of the ventilation pipe arrangement room 1. The specification of the inlet and outlet is 600mmX400mm, and a ladder 6 is provided between the inlet and outlet 5 and the top plate of the ventilation pipe arrangement room 1. In order for the water on the hatch coaming 10 to enter the ventilation pipe arrangement room 1 through the inlet and outlet 5, water retaining plates 7 are provided around the inlet and outlet 5.
[0027] The outlet of the vent pipe 2 is fixed with a vent cap 3 to prevent debris from entering the ballast water tank through the vent pipe 2. The height difference between the vent cap 3 and the upper deck 13 is greater than or equal to 460 mm. A tank penetration sleeve 4 is arranged between the vent pipe 2 and the bottom plate of the vent pipe arrangement room 1 to ensure the water tightness of the bottom plate of the vent pipe arrangement room 1. The area of the water flow hole 9 is greater than or equal to the flow area of the largest vent pipe 2 to prevent the overflow water in the vent pipe arrangement room 1 from being discharged in time.
[0028] In order to reduce the difficulty of opening holes in the bottom plate of the air vent arrangement room 1 and ensure the strength of the cargo hold bulkhead 11, the top plate of the cargo hold bulkhead 11 (i.e., the bottom plate of the air vent arrangement room 1) is made of non-crack arrest steel. In this embodiment, the distance between the air vents 2 is 600-700mm, so as to minimize the area occupied by the air vent arrangement room 1 while ensuring that there is space for installing the air cap 3.
[0029] This embodiment also provides a container ship, comprising the above-mentioned container ship ballast water tank vent pipe arrangement room 1.
[0030] The present application sets a ventilating pipe arrangement room between the cargo hold bulkhead and the hatch coaming. The ventilating pipe passes through the cargo hold bulkhead top plate. The outlets of the ventilating pipes are all set in the ventilating pipe arrangement room, avoiding opening holes on the upper deck of high-strength crack arrest steel, reducing the difficulty of opening holes, and ensuring the strength of the main deck. The water in the ballast tank will overflow along the ventilating pipe in certain states of the ship. In order to avoid the overflow water of the ventilating pipe flowing into the cargo hold of the container ship along the cargo hold bulkhead and contaminating the cargo, the side walls of the ventilating pipe arrangement room in the present application are all watertight walls, wherein a water flow hole is set below the side wall at the junction of the cargo hold bulkhead and the upper deck, so that the water overflowing along the ventilating pipe in the ballast tank flows to the upper deck and then discharged from the hull along the upper deck, reducing the possibility of overflow water flowing into the cargo hold along the cargo hold bulkhead top plate, and ensuring the transportation environment of goods in the container ship.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
