Water mist spraying connecting device for ship cargo hold

Abstract

The invention discloses a water mist spraying connecting device for a ship cargo hold. The water mist spraying connecting device is arranged between a water discharging pipe of a main fire-fighting system and a water charging pipe of a water mist spraying system of the cargo hold; the part, positioned below a deck II, of the cargo hold wall is provided with a hollow part; the hollow part is internally provided with an internal hold wall and an oblique plate; the oblique plate extends obliquely and downwards from the internal hold wall to the hold wall; the lower end face, the internal hold wall and the oblique plate of the deck II define a recess mounting region in a surrounding manner; the water discharging pipe of the main fire-fighting system penetrates into the internal hold wall; theopening of the water discharging pipe of the main fire-fighting system is connected with a first quick connector; the water charging pipe of the cargo hold water mist spraying system penetrates into the sidewall of a hold cover; the opening of the water charging pipe of the cargo hold water mist spraying system is connected with a second quick connector; the first quick connector is connected withthe second quick connector through a hose; and an access cover is arranged at the upper surface of the hold cover. The water mist spraying connecting device disclosed by the invention has the advantages that the operation is simple, the hose is hard to damage and the like; the cargo space of the cargo hold is increased; the operation difficulty of loading and unloading is reduced; and the operation time is shortened.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a water mist spray connection device for a ship cargo hold. Background technique [0002] In accordance with the requirements of the International Convention for the Safety of Life at Sea, a water mist sprinkler system is required to be installed in the cargo hold of a ship carrying Class 1 explosives as defined by the International Maritime Dangerous Goods Regulations (IMDG). cool down. The spray pipeline is installed in the hatch cover, and water mist nozzles are installed at intervals on the pipeline, and the water mist sprayed by the nozzles needs to cover the entire bottom surface of the cargo hold. [0003] On ships equipped with cargo hold sprinkler system, the main fire protection system provides sprinkler water and is arranged in the side tank next to the cargo hold. Such as figure 1 As shown, the water inlet 101 of the sprinkler system is at the top of the cargo hatch ...

AI Technical Summary

Problems solved by technology

[0005] 1. The water supply end is in the side tank, and the water inlet end of the spray pipe is in the cargo hold. The crew needs to enter the two areas to connect the hose connectors respectively, which is not easy to operate;

[0006] 2. The connecting hose is completely exposed in the cargo hold. If the cargo hold catches fire, the connecting hose is easy to fuse;

[0007] 3. The cargo cannot be stacked at the hose, otherwise it will press the hose and block the water supply; thus, the cargo space in the cargo compartment will be lost;

[0008] 4. When loading and unloading, special attention should be paid to avoid damage to the relevant connectors, which increases the difficulty of loading and unloading operations and prolongs the operation time
