Description

Technical Field

[0001] The utility model belongs to the technical field of ships and relates to a ventilation component used for a cargo ship. Background Art

[0002] With the development of the shipping industry, ships and offshore platforms need to be designed to be closed due to the harsh environment. They cannot fully exchange fresh air with the outside world. The air contains pollutants such as odor, volatile gases and bacteria. The air pollution in the cabin not only destroys the working and living environment of the crew, but also directly threatens the health of the crew. In order to save energy, it is impossible to increase the frequency of air conditioning ventilation indefinitely, resulting in the inability to discharge pollutants in the cabin out of the cabin in time, causing the deterioration of the air quality in the cabin. Therefore, ship ventilation equipment has received more and more attention. However, in actual use, ventilation equipment is generally normally open, but in some occasions, it is necessary to control the closure of the vents. If they are not closed in time, external gas or liquid may enter the ship's hold, thereby affecting human health. At the same time, its ventilation volume is relatively fixed, which cannot meet the use needs. Summary of the invention

[0003] The purpose of the utility model is to provide a ventilation component that can seal the vent and solve the above problems in the prior art.

The outer wind hood and the inner wind hood are respectively arranged on the two end surfaces of the deck and connected thereto. The outer wind hood and the inner wind hood are arranged in a bowl-shaped structure. A through hole that connects the hollow cavity of the outer wind hood with the hollow cavity of the inner wind hood is provided on the end surface of the deck located at the outer wind hood, and a plurality of ventilation strip grooves are provided on the outer peripheral walls of the outer wind hood and the inner wind hood, which are spaced apart along their circumferential direction.

[0006] In the above-mentioned ventilation assembly for cargo ships, the opening and closing unit is composed of a hollow assembly shell and an opening and closing sleeve, a control switch, two assembly seats and a connecting shaft. The assembly shell is arranged at a through hole in the deck and connected thereto, and a folding ring connected thereto and in contact with the deck is arranged on the outer end of the assembly shell. The opening and closing sleeve is arranged in the assembly shell and slidably cooperates with the shell. The two assembly seats are arranged on the inner wind cover and connected thereto. The control switch is connected to the two assembly seats through a connecting shaft. A movable groove is provided on the end surface of the inner wind cover for the control switch to extend out and enable it to move around the connecting shaft. The control switch is connected to the opening and closing sleeve through a connecting unit.

[0007] In the above-mentioned ventilation assembly for cargo ships, an axial outward protrusion is arranged on the inner end surface of the outer wind cover, and cooperates with the opening and closing sleeve to form a sealed sealing protrusion.

[0008] In the above-mentioned ventilation assembly for cargo ships, the connecting unit is composed of an assembly frame and a connecting strip.
