Marine ventilation device

Abstract

The invention provides a marine ventilation device, and relates to the field of marine equipment. The device comprises a ventilation system and a ventilation tower, the ventilation system comprises an air feeder, an exhaust fan, an air supply pipeline and an exhaust pipeline, the ventilation tower is provided with an air supply outlet and / or an exhaust outlet, the air feeder is connected with the air supply outlet through the air supply pipeline, the exhaust fan is connected with the exhaust outlet through the exhaust pipeline, the ventilation tower comprises a tower cover and a tower column which are connected with each other, the interior of the tower column is communicated with a cabin, the exhaust outlet and the air supply outlet are both located in the side wall of the tower column, the tower cover comprises a cover plate and a shielding part arranged on the peripheral side of the cover plate, and the shielding part can shield the exhaust outlet and the air supply outlet. The device can achieve good ventilation in the ship cabin, and the ventilation device has waterproof measures which are reliable, good in effect, low in cost and free of manual operation.

Description

technical field [0001] The invention relates to the field of marine equipment, in particular to a marine ventilation device. Background technique [0002] With the advancement of ship engineering technology, people's requirements for the internal environment of ships are getting higher and higher. Generally speaking, the cabin is located inside the ship, and a fan is needed to pass air from the ventilator arranged on the deck into the cabin, so as to maintain the air circulation in the cabin and improve the environmental quality. [0003] In the case of strong wind and waves, personnel need to manually close the ventilator. When the wind and waves are large, it is difficult for the operator to close the ventilator in time. A large amount of seawater will enter the cabin through the tuyere, which will affect the safe operation of the equipment and seriously threaten the safety of the ship. run.

Problems solved by technology

[0003] In the case of strong wind and waves, personnel need to manually close the ventilator. When the wind and waves are large, it is difficult for the operator to close the ventilator in time. A large amount of seawater will enter the cabin through the tuyere, which will affect the safe operation of the equipment and seriously threaten the safety of the ship. run

In the prior art, most ventilation devices are waterproofed through more electrical structures, their performance is relatively unstable, the cost is high, and some require manual operation and control
