Problems solved by technology

Although this kind of fully submerged tunnel-line ship can avoid damage to the propeller due to the protruding bottom of the ship, the incoming flow of the propeller is relatively not smooth, and its speed, maneuverability, and slewing performance are relatively average.
[0007] Therefore, in view of the existing problems in the prior art, it is urgent to provide a hull structure technology capable of avoiding the damage caused by the propeller protruding from the bottom of the ship, and having better maneuverability, gyration, and quickness to solve the deficiencies in the prior art. especially important

Embodiment 1

[0043] One of the embodiments of a wide and shallow draft ship of the present invention, such as Figure 1 to Figure 6 means, such as image 3 As shown in , the hull structure with flat bottom and round bilge is set, such as Figure 4 , and the side structure is set in the form of a floating side structure, which refers to the oblique extension of the side structure above the design waterline, and the knuckle line of the side structure forms at least one sinking concave part from the bow to the stern . In the longitudinal direction, it gradually transitions to the round bilge towards the bow section and the stern section.

[0044] The ship adopts the streamlined design of the round bilge, and adopts the form of side structure floating above the load waterline. On the basis of fully ensuring the deck space, the width of the hull 1 at the waterline is reduced, and the resistance performance of the hull 1 is improved. And it adopts a wide and gentle bottom rise structure, whic...

Embodiment 2

[0048] One of the embodiments of a ship with wide and shallow draft of the present invention, such as Figure 1 to Figure 6 As shown, features that are not explained in Embodiment 2 are explained in Embodiment 1, and will not be repeated here.

[0049] Such as Figure 1 ~ Figure 4 As shown, the line shape of the main hull of an 83-meter beach-washing car-passenger ferry is provided. The line shape of the ship is dominated by longitudinal flow, and the line shape of the ship is arranged symmetrically from the bow to the stern, and only the middle and rear part of the main hull is shown in the figure.

[0050] The owner's dimensions are:

[0051] Total length: 83 meters,

[0052]Main hull length: 73.2 meters,

[0053] Molded width: 17.4 meters,

[0054] Molded depth: 3.3 meters,

[0055] Full load draft: 2.0 meters,

[0056] Empty draft: 1.5 meters,

[0057] In this embodiment, the chamfer line is configured as a chamfer line with two sunken recesses.

[0058] Specifica...

Abstract

The invention provides a wide shallow-draft ship. The wide shallow-draft ship is provided with a flat-bottom round bilge line type ship body structure, and each side structure is arranged to be of an outer bay side structure form, and at least one sunken concave part is formed on the chine of each side structure from the prow to the stern. According to the wide shallow-draft ship, a ship body is smooth and fair, steering oars are mounted on the sides and works in an extremely excellent flow field, various performance indexes including the rapidity, maneuverability, stability, safety and the like of the ship can be remarkably improved, and the wide shallow-draft ship has great development value. The ship body of the wide shallow-draft ship mainly can be used for islands and fairways with imperfect wharf facilities, the requirement for large vehicle transportation in certain water areas without wharf construction conditions can be met by means of the landing function based on maneuvering beaching, and the wide shallow-draft ship is an important supplement for traffic and transportation in relative backward countries or areas with severe natural environments.

Description

technical field [0001] The invention relates to the technical field of ship hull structure, in particular to a ship with wide and shallow draft. Background technique [0002] At present, most ferries need to have fixed docks to berth, and they have higher requirements on the facilities and water depth of the docks. And in some beaches that do not have a pier, you need to flush and land on the beach. In the prior art, the propellers of most ships all adopt the "tail propulsion mode" propellers, that is, fixed propellers, adjustable propellers or full-turn rudder propellers are installed at the tail of the hull. However, for some special ship types, such as beach landing ferries with propellers symmetrically arranged from head to tail, in order to prevent the propeller from being damaged during beach landing, the propeller cannot protrude beyond the bottom of the ship. " propeller just seems to be difficult to adapt. Moreover, using the "tail propulsion mode" propeller of t...
