Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ship ventilation, in particular to an anti-water seepage ventilation device for a ship deck. Background Art
[0002] With the continuous development of ships, the tonnage of ships is getting larger and larger, and at the same time, the requirements for the comfort, safety and aesthetics of ships are getting higher and higher. Therefore, almost all cabins such as living cabins and working cabins of ships are equipped with ventilation, and the air inlets of ventilation ducts are usually installed on the deck of the ship.
[0003] When installing the existing ventilation duct air inlet, the air inlet duct is only fixed by bolts. However, when there is water accumulation on the deck or on rainy days, water can easily penetrate into the duct, causing water flow in the ventilation duct. When the water flow penetrates too much, it will also enter the cabin, which not only affects the life of the crew but also easily causes damage to some equipment. Therefore, we propose an anti-water seepage ventilation device for ship decks. Utility Model Content
[0004] The utility model aims to provide an anti-water seepage ventilation device for a ship deck. By setting a sealing component, specifically when it rains or water accumulates, the water that penetrates from the bottom of the conical guide pipe into the interior will be discharged through the drainage groove. When the water accumulates too much, the close contact between the sealing ring 1 and the sealing ring 2 can play a first sealing role, and the close contact between the rubber pad and the annular seat can play a second sealing role, thereby preventing the water from penetrating into the connecting pipe, effectively ensuring the normal ventilation of the pipe, and will not affect the life of the crew, and also protecting the equipment from damage. It solves the problem that when there is water accumulation on the deck or on rainy days, the water easily penetrates into the inside of the pipe, thereby causing water to exist in the ventilation pipe. When the water penetrates too much, it will also enter the cabin, which not only affects the life of the crew, but also easily causes damage to some equipment.
