Improved box-type closable rain-proof tuyere for ships

Abstract

The invention provides an improved box-type closable rain-proof tuyere for ships, comprising: the web is sequentially connected with the rubber pad, the seat plate, and the bulkhead of the bow bulwark of the ship; the outer frame plate is connected with the web board connection; the rainwater separation device is connected to the outer frame plate, and the rainwater separation device includes a waterproof louver and a hook connected to the outer frame plate; the panel is separated from the waterproof louver by a preset distance; the watertight cover is provided with a screw seat, and the watertight cover and the guide post Flexible connection; after the screw rod passes through the screw rod seat, one end is connected to the outer frame plate, and the other end is connected to the rotating device through the through hole on the panel. The invention can ensure the watertight separation between the ventilation duct and the outside world in general sea conditions, and ensure the unobstructed air intake and exhaust of the ventilation duct, so as to meet the requirements of cabin ventilation under general sea conditions; , Operate the watertight cover through the rotating device, control its sealing condition, and ensure that the ventilation pipe is completely separated from the outside by water and air.

Description

technical field [0001] The invention relates to ship technology, and is particularly suitable for ventilating outlets for mechanical exhaust and natural air intake in bow cabins of ships. Background technique [0002] With the expansion of naval missions, ocean-going missions are performed more frequently and for longer periods of time, and the probability of encountering various high sea conditions is getting higher and higher. At present, the box-type closable rain-proof tuyere installed at the new bulwark at the bow has met the specifications and aesthetic requirements. As the probability of ships encountering high sea conditions is getting higher and higher, when the ship is bowed, the original box-type closable rain-proof tuyere is hit by high-intensity seawater, resulting in the closure of the original box-type closable rain-proof tuyere watertight cover. Therefore, the original box-type closable rain-proof tuyere can no longer meet the complete watertight isolation f...

Problems solved by technology

As the probability of the ship encountering high sea conditions is getting higher and higher, when the ship is in the bow state, the original box-type closable rain-proof tuyere is subjected to high-intensity impact of sea water, resulting in the closure of the original box-type closable rain-proof tuyere watertight cover.

Therefore, the original box-type closable rain-proof air vent cannot meet the complete watertight isolation from the outside world due to seawater slamming when the ship is bowed. It is necessary to develop a new type of air vent that meets the design requirements of the ventilation system under high sea conditions.
