Arc-shaped ship bow molded line design for dredging green water of high speed vessel

[0015] Such as figure 1 , figure 2 with image 3 As shown, an arc-shaped bow line design for dispersing waves on the deck of a high-speed ship, the wave discharge part 1 occupies one third of the total length of the hull, and the outer hull of the bow includes: a wave discharge part 1 and a main body Section 2; the wave-discharging parts 1 on both sides of the hull are symmetrical to each other, the wave-discharging part 1 includes: a straight part 11, a streamline part 12, a groove part 13, an arc part 14 and an inclined part 15; the bow An arc-shaped main body 2 is provided below the outer hull. The top end of the main body 2 is arc-shapedly connected to the straight portion 11 at the bottom end of the wave discharge portion 1. The straight portion 11 is a straight plate-shaped structure that can block the straight The waves below the section 11 do not impact the upper wave section 1, allowing the waves on the wave section 1 to be easily discharged outside the hull, enhancing the seakeeping of the ship. The streamline section 12 is connected above the straight section 11, so The streamline part 12 is from the outside of the hull to the inside of the hull. The upward and horizontal angle is 2 degrees to 5 degrees, preferably the included angle is 3 degrees, so that the waves on the streamline part 12 can more easily flow out of the hull. The smooth transition above the streamline portion 12 is connected with a groove portion 13, and the inside of the groove portion 13 is a streamline smooth groove. The groove portion 13 on the wave discharge portion 1 forms a channel from the bow to the stern. So that most of the waves raised in the front part of the ship can be discharged out of the hull through the wave discharging part 1. The arc part 14 is smoothly connected to the upper part of the groove part 13 and the arc part 14 extends from the inside of the hull to In the outer direction of the hull, the angle between the upward and horizontal position is 47°-57°, preferably 52°, so that the waves rushing toward the hull hit the groove 13 and the arc 14 and play a buffering role. , Which reduces the shaking of the hull and enhances the stability of the hull. There is an inclined part 15 above the arc-shaped part 14. The inclined part 15 extends from the outside of the hull to the inside of the hull, and the angle between the upward and the horizontal position is 7 Degrees -13 degrees, the preferred angle is 10 degrees, so that the waves on the deck can easily flow out of the hull from the inclined portion 15, avoiding entering the interior of the deck, causing a large amount of sea water to surge onto the deck, and avoiding huge impact on the deck. The equipment, cargo and superstructure on the ship cause damage, and the cargo on the deck may also be washed away, causing huge losses. The wave discharge part and the main part of the outer hull of the bow are arc-shapedly connected with other structures of the hull.

[0016] When the ship is sailing, there will be big waves. The waves rising above the deck will rush to the inclined part 15 of the wave discharge part 1, and then slide out of the hull along the inclined part 15 and rise below the deck, straight part Waves above 11 will hit the groove part of the wave discharge part 1, reducing the impact force, and then flow out along the streamline part 12 and the straight part 11 and discharged outside the hull, reducing the impact of waves on the hull and improving This improves the seakeeping of the ship, improves the safety and comfort of the ship, reduces the resistance of the ship during navigation, reduces fuel consumption, and effectively solves the problem of waves on deck affecting ship performance.

[0017] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Anyone familiar with the technical field within the technical scope disclosed by the present invention, according to the technical solution of the present invention Equivalent replacements or changes to its inventive concept should all fall within the protection scope of the present invention.
