Ship outer plate ventilation structure, ventilation system applying ventilation structure and ship

Abstract

The invention discloses a ship outer plate ventilation structure, a ventilation system applying the ventilation structure and a ship. An air duct wall plate used for isolating a first structure air duct from a second structure air duct is arranged between the ship outer plate and the cabin. A shielding net module is embedded in the inner side of an outer plate of the front wall of the first structure air duct; a gas-water separation module is fixed to the shielding net module, a pneumatic shutter module is fixed to an air duct wall plate on the rear wall of the first structure air duct, a pneumatic executing mechanism is hinged and fixed to the pneumatic shutter module, a manual operation mechanism is arranged at the end of the pneumatic executing mechanism, and a deck water leakage opening is formed in a bottom plate of the first structure air duct. The air duct is simple in structure, easy to install and arrange, convenient to overhaul and high in operation efficiency, waves or rainwater is effectively prevented from invading a cabin, the air duct of the structural type is high in drainage capacity and high in effective ventilation rate, radar waves can be effectively scattered through the shielding net structure, and the good stealth effect is achieved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a ventilation structure of a ship's outer plate, a ventilation system and a ship using the ventilation structure. Background technique [0002] With the increasing development of ship ventilation technology, more and more attention is paid to the ventilation openings on the ship's outer plate (also collectively referred to as "outer plate ventilation shutters"). In addition to basic functions such as preventing seawater, rainwater and rats from entering the cabin through the opening, the radar wave reflection effect formed by the above-mentioned vents in special ships, the weatherproof effect of the ship when sailing in harsh sea conditions, and the appearance of the external opening of the ship should also be considered performance and operating efficiency of shutter opening or closing etc. [0003] The traditional ventilating louvers on the ship's outer plate mainly adopt...

AI Technical Summary

Problems solved by technology

[0003] The traditional ventilating louvers on the ship's outer plate mainly adopt two basic forms: louvers with weathertight covers and louvers without doors. They only consider the sealing effect of the ship to prevent rainwater from penetrating into the cabin by closing the louvers under wind and waves. The air duct where the shutters on the outer panel are located lacks overall design considerations, and it is difficult to take into account the radar wave reflection effect of the shutters on the outer panel, the rainproof effect, drainage capacity, and closing efficiency of the shutters on the outer panel, which seriously affects the completion of ships and ship-related tasks.
