Some embodiments of the invention are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.
Example 1
As shown in fig. 2, the hull structure of the present invention includes a main body 100, a hull 200, and a deck 300.
The deck portion 300 is disposed above the main body portion 100, the deck portion 300 has a deck extension portion 310 extending outward relative to the main body portion 100, the outer side of the main body portion 100 is provided with an outer float portion 200 extending outward away from the hull and inclined upward, and the outer float portion 200 is supported below the deck extension portion 310.
According to the outward floating type hull structure provided by the invention, the outward floating part 200 extends outwards to support the deck extending part 310, the outward floating part 200 can extend from the bow to the stern, the requirement of enlarging the deck area at the bow and stern parts is met, the operation area of the deck is greatly increased, the outward floating part 200 inclines upwards, the weight is light, and the influence on the draught depth of a ship racket is avoided.
Further, in a cross section perpendicular to the longitudinal direction of the hull, a cross section line 201 of the flare portion 200 is a straight line.
Specifically, the cross section 201 of the flare portion 200 is a projection of the outer side wall of the flare portion 200 in a cross section perpendicular to the longitudinal direction of the hull, and in the present embodiment, the cross section 201 of the flare portion 200 is a straight line.
Further, the included angle between the horizontal line 201 of the outer floating part 200 and the horizontal plane is gradually reduced from the transverse central line of the ship body to the bow direction.
From the transverse central line of the ship body to the stern direction, the included angle between the transverse cross-section line 201 of the outer floating part 200 and the horizontal plane is gradually reduced.
The cross-sectional line 201 of the flare portion 200 is a projection of an inclined surface on the outer side of the flare portion 200 in a cross section perpendicular to the longitudinal direction of the hull.
In particular, in this embodiment, the transverse center line of the hull is the center line of the hull in the direction perpendicular to the deck plane in the length direction thereof, i.e. the distances from the transverse center line of the hull to the fore and aft are the same.
The outboard float part 200 of the ship body can be cut into a plurality of sections in the direction vertical to the length direction of the ship body, a transverse section line 201 can be obtained in each section, and the included angle between the transverse section line 201 of the outboard float part 200 and the horizontal plane is gradually reduced from the transverse central line to the ship bow direction.
Meanwhile, the included angle between the horizontal section line 201 of the flare portion 200 and the horizontal plane is gradually reduced from the transverse centerline toward the stern direction.
Since the width of the main body 100 is gradually reduced from the transverse center line toward the fore and aft directions when the hull is structurally designed, in order to adapt to the structure of the main body 100 and make the main body 100 and the deck 300 transition better, the above-mentioned structure form is adopted in which the included angle between the transverse cross-sectional line 201 of the flare portion 200 and the horizontal plane is gradually reduced.
Preferably, the cross-sectional line 201 is at an angle to the horizontal ranging from: 30-60 degrees.
Further, the bottom of the outer float 200 is located above the design water line a.
Specifically, the bottoms of the floating parts 200 are located above the design waterline a, that is, the connection part of the main body part 100 and the floating parts 200 is located above the hull design waterline a, so that the working area of the deck part 300 is increased without increasing the displacement of the hull, and the contradiction between the small type width of the ship design waterline a and the large requirement of the working area of the deck part 300 is solved.
Further, the distance between the bottom of the outer float part 200 and the design water line a is greater than or equal to the sense wave height.
Specifically, in this embodiment, the distance between the junction of the outer floating part 200 and the main body part 100 and the design water line a is equal to the sense wave height, and the so-called water sense wave height is the average value of the wave heights during the ship navigation process, and can be obtained by those skilled in the art according to the prior art, which is the basic common knowledge in the field and will not be described herein again.
Further, the junction between the main body 100 and the outer fluttering portion 200 is in an arc-shaped transition structure.
Specifically, the main body 100 and the outer floating portion 200 may be connected together by an arc structure, and the arc structure may reduce stress concentration at the joint of the main body 100 and the outer floating portion 200, improve strength of the hull, and maintain safety during navigation.
In the main body 100, the width of the main body 100 gradually increases from the design waterline a to the upper end of the main body 100, and the connection between the main body 100 and the transition is in an arc structure, thereby further improving the strength of the hull.
Further, the distance from the outer side surface of the deck extension 310 to the longitudinal centerline of the hull is the same in the longitudinal direction of the hull.
The longitudinal centre line of the hull is the centre line of the hull in the direction perpendicular to the deck plane in its width direction, i.e. the distance from the longitudinal centre line of the hull to both sides of the hull is the same.
Specifically, the width of the deck portion 300 is the same from the bow to the stern in the length direction of the entire hull, and the connection with the main body portion 100 through the outer float portion 200 provides support for the deck portion 300, so that the width of the deck can be kept consistent from the bow to the stern, thereby increasing the area on the deck to the maximum extent and facilitating the operation on the deck.
Fig. 1 is a schematic view of a conventional ship type in the prior art, the width of the deck at the deck is substantially the same as the width of the ship at the waterline, and the area of the conventional line type deck is closely related to the width of the ship at the waterline. In order to increase the working area on the deck, one method is to increase the overall size of the vessel to increase the area of the deck, which results in an increase in the overall displacement of the vessel; the other method is to increase the operation area of the deck by adopting an externally-hung buoyancy tank to meet the task requirement, the method is limited by factors such as the structural strength of the ship body, the stability of the ship and the like, the width of the buoyancy tank is relatively small, the operation area of the deck is increased in a limited manner and is influenced by the linear change of the fore and the stern, and the buoyancy tank can only be externally hung in the midship area of the ship and cannot meet the requirement of increasing the area of the fore and stern decks. The outer floating type hull structure provided by the invention utilizes the outer floating part 200 to extend outwards so as to support the deck extending part 310, the outer floating part 200 can extend from the bow to the stern, the requirement of enlarging the deck area at the bow and stern parts is met, the operation area of the deck is greatly increased, and the outer floating part 200 inclines upwards, so that the weight is light, and the influence on the draught depth of a ship racket is avoided.
