Abstract
A semi-submersible barge provided with a wing wall with a large hole comprises a main barge body. A lifting deck is arranged on an upper portion of the main barge body, a wing wall is arranged on both sides of the lifting deck, a hole is arranged in the middle of the wing wall, a deckhead is arranged at the top of the wing wall, and a safe deck is arranged below the deckhead. The hole is rectangular, the lower end of the hole is parallel to the lifting deck, and the upper end of the hole is parallel to the safe deck. Inserted thickened boards are respectively arranged between the positions where two upper vertex angles of the hole are connected with the safe deck. The length of the hole accounts for 30% of that of the barge. The hole portion is located near the neutral axis of the barge body and contributes little to the total longitudinal strength, therefore structure weight can be reduced greatly by removing the hole portion and the effect to the total longitudinal strength is small, and further adoption of the form has great advantages in total steel use amounts in a large scale semi-submersible barge. In addition, as the top of the wing wall is continuous, areas of facility layouts and seamen residence are greatly increased. Provided with the hole, the wing wall effectively reduces a wind area of the barge and contributes to the sailing and the anchoring safety.

Large-scale half latent floor space of refuting is a very important index, and it is directly connected to the scope of carrying deck cargo.Along with the increase of water conservancy project project and marine engineering, the half-and-half latent demand of refuting of people is also increasing in recent years.For can the more specifications of carrying or the product of quantity, the shipowner often wishes that the side of design increases the effective bearing area on deck as much as possible, and traditional half dives to refute is generally island formula structure.The captain surpasses 65 meters, all needs longitudinal strength is checked by standard.Half dives to refute is generally flat box hull, and moldeed depth is less, and the captain increases the back for satisfying the longitudinal strength requirement, needs to increase big dimension material and improves structural strength.The box that surpasses 65 meters for the captain is refuted, and requires needs to increase great deal of steel for satisfying longitudinal strength, and along with this drawback of captain's increase is more obvious.
The utility model content
In order to address the above problem, the utility model provides a kind of half latent refuting that is provided with the large opening wing wall.
The utility model is that the technical scheme that its technical matters of solution is adopted is,
Be provided with half latent refuting of large opening wing wall, comprise main body, main body top has the lifting deck, and two sides of a ship on the lifting deck are provided with wing wall, and the middle part of this wing wall is provided with perforate, and the wing wall top is provided with flying deck, and the below of flying deck is provided with the safety deck.
Described perforate is a rectangle, and perforate lower end and lifting deck maintain an equal level, and the perforate upper end maintains an equal level with the safety deck.
Described perforate two on drift angle and junction, safety deck be respectively equipped with embedded thickening plate.
Described perforate length is captain's 30%.
The beneficial effects of the utility model are, aperture portion is positioned near the neutral axis of hull girder, contribution to longitudinal strength is little, remove and to alleviate structural weight in a large number, and it is very little to the longitudinal strength influence, such form is dived for half of large scale and is refuted, advantageous on total steel using amount, in addition because the wing wall top is continuous, increased the area that facility location and crewman live greatly, provide very large space for improving crewman's condition of living, actv. has reduced the area exposed to the wind of boats and ships after the wing wall perforate, and contribution has also been made in navigation and mooring safety.
Description of drawings
Fig. 1 is half structural representation of diving and refuting that the utility model is provided with the large opening wing wall.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, half latent the refuting that is provided with the large opening wing wall that the utility model proposes comprises main body 100, main body 100 tops have lifting deck 110, two sides of a ship on lifting deck 100 are provided with wing wall 200, the middle part of this wing wall 200 is provided with perforate 210, wing wall 200 tops are provided with flying deck 230, and the below of flying deck 230 is provided with safety deck 220.
