Marine conformal ventilation device

Abstract

The marine conformal ventilation device comprises a ventilation trunk body and a bulwark T-shaped profile, the ventilation trunk comprises a deck upper-layer trunk shell and a deck lower-layer trunk shell, an included angle is formed between the deck upper-layer trunk shell and a bulwark, and the bulwark T-shaped profile comprises a T-shaped profile web and a T-shaped profile panel. The deck upper-layer trunk shell is divided into an upper-layer air inlet channel and an upper-layer air outlet channel through the T-shaped material web, the deck lower-layer trunk shell is divided into a lower-layer air inlet channel and a lower-layer air outlet channel through the center partition plate, an air inlet trunk and an air outlet trunk are correspondingly formed, and communicating openings are formed in the positions, in the air inlet trunk and the air outlet trunk, of the deck. And ventilation openings are formed in the positions, corresponding to the tops of the air inlet trunk and the exhaust trunk, of a back plate of the trunk shell on the upper layer of the deck, maintenance windows are correspondingly formed in panels, and ventilation pipes are correspondingly arranged on panels of the trunk shell on the lower layer of the deck. The waterproof performance is good, and the tidiness of the weather deck surface is improved.

Description

technical field [0001] The invention belongs to the technical field of atmospheric environment control systems for ship cabins, and in particular relates to a marine conformal ventilation device. Background technique [0002] Since the ship cabin is a relatively closed space, the ship ventilation system needs to set up a ventilation device at the perimeter of the hull to conduct centralized air intake and exhaust to meet the ventilation and ventilation requirements of the cabin. At present, the ship ventilation system is generally equipped with mushroom-shaped ventilators and gooseneck ventilators on the open deck, or a weathertight air grille is set on the outer plate structure as a ventilation device. The fungus-shaped ventilator and gooseneck ventilator will occupy a certain area of ​​the open deck, and in order to meet the requirements of the distance between the air inlet and the air outlet, a large number of ventilators need to be installed, which will cause the open d...

AI Technical Summary

Problems solved by technology

Mushroom-shaped ventilators and gooseneck ventilators will occupy a certain area of ​​the open deck, and in order to meet the requirements for the distance between air inlets and exhaust outlets, a large number of ventilators need to be installed, which makes the open deck unsightly, and affects the passage of personnel and the deck. Operations, etc.; the weathertight air grille is embedded and installed on the outer panel structure, which has a neat and beautiful appearance, but its ability to prevent water ingress is poor, and it is very easy for water to enter under the condition of strong wind and waves, causing the ventilation system to fail to operate normally
