Problems solved by technology

[0004] However, the draft of the ship under heavy load conditions may exceed the design draft. At this time, the bulbous bow 1 is not below the water surface, so the bulbous bow 1 cannot offset the wave-making resistance generated by the water waves above it, thereby affecting the speed of the ship.

Embodiment Construction

[0016] In order to further illustrate the principle and structure of the present invention, preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0017] The present invention takes the position of the bow as the front when describing the position, and the position of the stern as the rear.

[0018] refer to figure 2 and image 3 , The bow structure of the container ship of the present invention includes: a bulbous bow 1 located below the front of the bow and a pointed bow 2 located above the front of the bow, and the pointed bow 2 and the bulbous bow 1 are integrated.

[0019] The bulbous bow 1 extends forward from the stem 3 of the container ship, its topmost contour line 11 is roughly horizontal, and the boundary line between the front end surface and the longitudinal midsection of the hull is an arc extending smoothly downward from front to back. The outline of the cross-section of the bulbous bow 1 ...

Abstract

The invention relates to a head structure of a container ship. The head structure of the container comprises a bulbous bow below the front portion of a ship head. The top end of the bulbous bow is higher than a designed waterline of the container ship and lower than a structural waterline of the container ship. By changing the height of the bulbous bow, the top end of the bulbous bow is higher than the designed waterline and lower than the structural waterline. Thus, the resistance performance between the designed waterline and the structural waterline of the ship can be improved and rapidity between the structural waterline and the designed waterline of the ship is improved.

Description

technical field [0001] The invention relates to the field of ship design, in particular to the bulbous bow structure of a container ship. Background technique [0002] The draft of a ship refers to the depth to which the ship is submerged in water, which varies according to the design of the ship. The size of the draft depends not only on the weight of the ship and everything on board such as cargo, ballast, fuel and spare parts, but also on the density of the water in which the ship is standing. The draft of a ship can be determined by reading the water gauges marked on the bow and stern of the ship. The draft of a ship is the design draft and the structural draft. The design draft of the ship refers to the draft corresponding to the full load of the ship under the design state. The structural draft of the ship refers to the maximum draft that the hull structure can bear. Refer to figure 1 , the bow of the ship is usually marked with the structural waterline β and the des...
