Description

Technical Field

[0001] The utility model relates to the field of ship structures, in particular to a two-way water suction port applied to the bottom of a ship. Background Art

[0002] The ship's pressure water intake is an important component on the ship. It plays a key role in the operation of the ship. It is located at the bottom of the ship so that it can fully absorb the pressure water.

[0003] Common ship water intakes are in the shape of square seawater tanks or vertical straight-cylinder water intakes. The square seawater tanks are larger in size, and the vertical straight-cylinder water intakes have lower water intake efficiency. They all intake water vertically upward and cannot utilize the impact of the water flow to intake water. The one-way ramming water intake can only improve the one-way water intake efficiency, but the water intake efficiency is low when the ship is reversing, and there may be a situation where the water intake is insufficient when reversing. Utility Model Content

[0006] In some embodiments, the water inlet cylinder is vertically arranged, the first water guiding cylinder is tilted backward by 45 degrees, and the second water guiding cylinder is tilted forward by 45 degrees.

[0007] In some embodiments, the first water suction port is provided with a first water inlet grille; the second water suction port is provided with a second water inlet grille.

[0008] In some embodiments, the first water inlet grille and the second water inlet grille have a plurality of strip-shaped holes.

[0009] In some embodiments, the first water inlet grille and the second water inlet grille have a plurality of circular holes.

[0010] In some embodiments, a flange for communicating with a valve is provided on the top of the water inlet cylinder.

[0011] In some embodiments, the first water suction port and the second water suction port are both flush with the bottom of the hull.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] The two branches of the water inlet cylinder with a Y-shaped structure at the bottom of the present application have a certain inclination in both the front and rear directions. When the ship is moving forward or reverse, they have a certain overlap with the water flow direction, which can facilitate the water flow into the water inlet cylinder and improve the water intake efficiency.
