Description

Technical Field

[0001] The utility model relates to a main hull, in particular to a main hull of a large ship. Background Art

[0002] The main hull is also called the main body of the ship. It refers to the upper deck (or strong deck) and the hull part below it. The deck and the outer plate of the hull form a watertight ship body. As the main part of the hull structure, the main hull is the main structure to ensure the hull strength and floating ability.

[0003] The existing large ships have bulbous bows below the waterline to reduce the wave resistance of the ship during navigation and improve the energy efficiency and comfort of the ship. However, the cost of the bulbous bow is very high. The total cost of installing a bulbous bow on a large ship is more than 1 million US dollars. It is well known that the mooring and berthing operations of large ships are difficult to carry out, and the bulbous bow is prone to damage. In addition, the bulbous bow is prone to get stuck in the anchor chain when the ship is anchored. In order to solve the problems of the conventional teardrop-shaped bulbous bow, the existing technology has developed a straight up and down clipper bow and Figure 3 However, both the clipper bow and the blade bow have the problems of small underwater volume, narrow and long blocks, low space size and space utilization, and are easily affected by crosswinds and waves, and have poor stability.

[0006] Furthermore, the vertical height from the upper edge of the ship's side on the port and starboard sides to the upper middle side of the respective sides is the freeboard.

[0007] Furthermore, the position from the upper middle side of the port side and the starboard side to the bottom of the respective side anti-wave slapping parts is the draft.

[0008] Furthermore, the portion of the anti-wave-beating portion extending toward the bow to the keel coincides with the height of the upper center side.

[0009] Furthermore, the bottom of the anti-wave-beating part is a flat-bottom arc.

[0010] Furthermore, the free end side of the ram bulbous bow extending from the connection side with the bottom of the ship to the bow side is gradually upturned and narrowed.

DETAILED DESCRIPTION

[0018] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] like Figure 1-2As shown together, the present embodiment is about a main hull of a large ship, including a bow 13, a stern 14, a port side 1 and a starboard side 2. In the present embodiment, the port side 1 and the starboard side 2 are symmetrically arranged. The present embodiment includes a keel 8 connecting the bow column and the stern column and extending longitudinally. It should be noted that the bow column and the stern column are buildings on the deck, so they are not shown in the figure. The present embodiment also includes an anti-wave slapping part 9 located between the hull and the bottom 3. A forward-extending ram bulbous bow 4 is formed on the lower side of the bow 13. The ram bulbous bow 4 includes a triangular immersion part 10 located at the lower side, a wave-breaking part 11 located on the port side 1 and the starboard side 2, and the wave-breaking part 11 extends to one side of the bow 13 and is connected to the anti-wave slapping part 9. The connection between the anti-wave slapping part 9 and the hull is the lower middle side 6, and the port side 1 and the starboard side 2 are both provided with an upper middle side 5.

[0020] In this embodiment, the length between the port side 1 and the starboard side 2 of the middle section of the main hull is the molded width. This embodiment is also preferably applied to the design in which the width of the stern 14 is narrower than the width of the bow 13. The solution combined with this embodiment can improve the stability of the ship, reduce water resistance, and increase the speed; the vertical height between the upper edge 7 of the side of the port side 1 and the starboard side 2 to the upper middle side 5 of each side is the freeboard.

[0021] Preferably, the position from the upper middle side 5 of the port side 1 and the starboard side 2 to the bottom of the respective side anti-wave slapping part 9 is the draft, such as Figure 1 As shown, the lowest position of the triangular immersed portion 10 is lower than the bottom of the anti-wave slapping portion 9, but the corner bulbous bow 4 is designed to be upturned and due to the mechanical effect during navigation, the main hull tilts from the upright position toward the bow 13, so that the bow draft is greater than the stern draft. Therefore, during navigation, the vertical height between the upper middle side 5 and the anti-wave slapping portion 9 is the draft. It should be noted that the mechanical analysis of the main hull during navigation is generally mastered by technical personnel in this field.

[0022] The portion of the wave-resistant portion 9 extending toward the bow 13 to the keel 8 coincides with the height of the upper center side 5. Therefore, it can be understood that the further the wave-resistant portion 9 extends toward the stern 14, the lower the draft position is, thereby further enhancing the draft stability of the main hull. Moreover, the design of the wave-resistant portion 9 protruding toward the port side 1 and the starboard side 2 can offset the problem that the ram bulbous bow 4 has a smaller underwater volume than the traditional teardrop-shaped bulbous bow and is easily affected by crosswinds and waves. Thus, the ram bulbous bow 4 is not easy to get stuck with the anchor chain and has good wave-breaking performance, while ensuring the ability of the main hull to resist crosswinds and waves.

[0023] In order to further enhance the buoyancy stability of the main hull, the bottom of the anti-wave-beating portion 9 is designed to be a flat-bottomed arc.

[0024] The free end side of the ram bulbous bow 4 extending from the connection side with the bottom 3 to the bow 13 side is gradually upturned and narrowed, which strengthens the wave-breaking performance of the ram bulbous bow 4, is not easy to get stuck by the anchor chain, and can also significantly enhance the turning performance and turning performance of the ship.

[0025] Furthermore, the position of the free end point of the ram bulbous bow 4 does not exceed the position of the end point of the bow 13, that is, when viewed from the side, the end point of the bow 13 is the outermost end. Such a setting is conducive to ensuring performance while increasing the waterline length, and has significant economic benefits for ships entering and leaving ports, passing through canals, etc.

[0026] The upper edges 7 of the ship's side on the port side 1 and the starboard side 2 near the stern 14 are both provided with side extensions 12 extending outward from the hull, and the side extensions 12 are used to increase counterweight or set outboard facilities.

[0027] The present application discloses a main hull of a large ship, which is preferably designed to have a bow width greater than a stern width, so as to improve the stability of the ship, reduce water resistance, and increase the speed. The teardrop-shaped bulbous bow of a non-military large ship is designed to be a ram bulbous bow. Different from the traditional ram bulbous bow, the ram bulbous bow of this embodiment has better wave-breaking resistance performance at the lower end, and the upturned design is conducive to ensuring the seaworthy positive floating position of the ship, and is not easy to get stuck in the anchor chain. The correspondingly designed anti-wave slapping part strengthens the draft stability of the main hull, especially the ability to resist crosswinds and cross waves.

[0028] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also belong to the protection scope of the present invention.
