Problems solved by technology

However, there are dense blades arranged inside the ventilation fan, and when the ventilation fan stops rotating, when water enters the side tank across, the dense blades will cause a huge blockage to the flow of gas in the ventilation duct
Therefore, in the existing ventilation design, the sum of the cross-sectional area of ​​the narrowest part of the ventilation duct (that is, the position of the ventilation fan) is difficult to meet the requirement of not less than 10% of the cross-sectional area of ​​the water inlet, which will lead to the anti-overturning performance of the ship. reduce

Embodiment 1

[0048] Such as Figure 1-3 As shown, this embodiment proposes a ship, which includes side tanks 1 arranged on the left and right sides of the ship. The space between the two and the upper part of the water inlet channel 2 is the midship equipment room 5 . The side tanks 1 on the left and right sides of the ship are respectively provided with a ventilation device for ventilation. The two ventilation devices have the same structure. Among them, such as figure 2 As shown, one end of the air inlet pipeline 3 is connected to the outside of the ship, the other end of the air inlet pipeline 3 is provided with a natural air outlet, and the natural air outlet is provided with a natural air outlet gate 31; the air inlet pipeline 3 is connected to one end of the outside of the ship It communicates with the natural air outlet to form a natural air inlet; the end of the air inlet pipeline 3 that is not connected to the outside of the ship is also provided with a forced air inlet; The t...

Embodiment 2

[0061] Such as Figure 4-6As shown, the present embodiment proposes a kind of ship, and its structure is exactly the same as the structure of the ship proposed in the first embodiment, the difference is only in the progress of the ventilating device of the side tanks 1 on the left and right sides of the ship proposed in the present embodiment. The air outlet of air duct 3 has only natural air outlet, and forced air intake fan 32 and supporting forced air intake gate 33, air supply pipe 34 and air supply air grid 35 are no longer set. However, the sum of the flow areas of the natural air inlet and the natural air outlet of the ventilation device in any side tank 1 of the present embodiment is not less than 10% of the cross-sectional area of ​​the water inlet passage, so it can also It is guaranteed to improve the anti-overturning ability of the ship under the premise of meeting the requirements of forced ventilation and fire closure ventilation.

Abstract

The invention relates to the field of a ship and discloses a ship and ship side cabin ventilation method. The ship comprises side cabins arranged on two sides of the ship, wherein the side cabins arecommunicated through a transverse water inlet channel, a ventilation device is arranged in each side cabin, one end of an air inlet pipeline of each ventilation device is communicated with the outsideof the ship, a natural air outlet is formed in the other end of the air inlet pipeline of each ventilation device, a natural air outlet gate is arranged at each natural air outlet, one end of an exhaust pipeline of the ventilation device is communicated with the outside of the ship, the other end of the exhaust pipeline is provided with a natural suction opening and a forced suction opening, thenatural suction opening is provided with a natural suction gate, the forced suction opening is provided with a forced suction fan and a forced suction gate, the sum of the circulation area of a natural air inlet channel formed by communicating an end, communicating with the outside of the ship, of the air inlet pipeline and the natural air outlet and the circulation area of a natural air outlet channel formed by communicating the natural suction opening and an end, communicating with the outside of the ship, of the exhaust pipeline is not smaller than 10% of the cross section area of the transverse water inlet channel. On the premise that requirements for forced ventilation and fire closing ventilation are met, the anti-overturning capacity of the ship is improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship and a ship side tank ventilation method. Background technique [0002] During the navigation of the ship, when one of the side tanks on the left and right sides of the ship is damaged, water will enter the side tank from the damaged opening. And when the water entering the side tank cannot rush to the side tank on the other side of the ship in a short period of time, it will cause asymmetric water ingress, which will easily cause the ship to capsize. [0003] In order to reduce asymmetrical water ingress and improve the ship's ability to resist capsizing. Generally, the side tanks arranged on the left and right sides of the ship are connected through the transverse water inlet passages of the ship's double bottom, that is, the side tanks on the left and right sides of the ship are connected with the transverse water inlet channels to form a "U-shaped cabin". In this way, w...
