Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a marine ventilation duct structure. Background Technology

[0002] Ships have many cabins, which are ventilated by ventilation ducts. Ventilation vents are installed on the ventilation ducts, and ventilation pipes are installed on the ventilation vents. The ventilation pipes lead to the outside of the cabins. However, during the ship's voyage, the waves will cause turbulence, and the seawater stirred up by the waves will enter the ventilation pipes, and then enter the cabins. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a ship ventilation duct structure that addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A ship ventilation duct structure includes a ventilation duct with a ventilation opening and an air exchange pipe connected to the ventilation opening. A support boss is provided inside the ventilation opening, and a tapered pipe is installed on the support boss. The upper end of the tapered pipe extends into the air exchange pipe and is close to the top of the air exchange pipe. An air outlet is provided in the middle of the tapered pipe, and a drainage hole is machined on the side wall of the ventilation opening at the bottom of the tapered pipe.

[0006] Furthermore, the ventilation pipe is a tee pipe, with the pipe in the middle of the tee pipe connected to the ventilation opening via a flange, and the pipes on both sides of the tee pipe serving as ventilation pipes.

[0007] Furthermore, the upper end of the tapered tube is 5-10 cm away from the top of the tee tube.

[0008] Furthermore, the bottom of the tapered tube is connected to a mounting boss, and the periphery of the mounting boss is fixed to the support boss by screws.

[0009] Furthermore, a sealing ring is provided between the mounting boss and the supporting boss.

[0010] Compared with the prior art, the ship ventilation duct structure of this utility model prevents seawater from entering the ventilation duct by setting a conical tube inside the ventilation pipe to block seawater and draining the seawater that has entered the ventilation opening through the drainage hole.

[0011] Figure 1 This is a schematic diagram of the structure of this utility model;

[0012] Among them, 1. ventilation duct, 2. ventilation opening, 3. air exchange pipe, 4. support boss, 5. tapered pipe, 6. air outlet, 7. drainage hole, 8. mounting boss, and 9. sealing ring. Detailed Implementation

[0013] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0014] like Figure 1 As shown, a ship ventilation duct structure includes a ventilation duct 1, a ventilation opening 2 on the ventilation duct 1, and an air exchange pipe 3 connected to the ventilation opening 2. A support boss 4 is provided inside the ventilation opening 2, and a tapered pipe 5 is installed on the support boss 4. The tapered pipe 5 blocks the ventilation opening 2. The upper end of the tapered pipe 5 extends into the air exchange pipe 3 and is close to the top of the air exchange pipe 3. An air outlet 6 is provided in the middle of the tapered pipe 5, and the air outlet 6 exchanges air with the air exchange pipe 3. A drain hole 7 is machined on the side wall of the ventilation opening 2 at the bottom of the tapered pipe 5, and the drain hole 7 discharges the seawater that flows back into the ventilation opening 2.

[0015] In this embodiment, the ventilation pipe 3 is a tee pipe. The pipe in the middle of the tee pipe 3 is connected to the ventilation port 2 by a flange. The pipes on both sides of the tee pipe are ventilation pipes. The bottom of the tapered pipe 5 is connected to a mounting boss 8. The mounting boss 8 is fixed to the supporting boss 4 by screws. A sealing ring 9 is provided between the mounting boss 8 and the supporting boss 4. The sealing ring 9 plays a sealing role. The upper end of the tapered pipe 5 extends into the tee pipe 5 to a distance of 5-10cm from the top of the tee pipe to prevent seawater from entering the ventilation pipe from the air outlet 6. At the same time, the tapered pipe 5 has a tapered surface on the outside, which plays a guiding role, so that the seawater gathers between the tapered pipe 5 and the ventilation port and is discharged from the drain hole 7 on the bottom side of the tapered pipe 5.

[0016] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
