Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Fig. 3 is a schematic structural view of a deck assembly according to an embodiment of the present application. Referring to fig. 3, the deck assembly includes a main deck 100, a decklid deck 200, and a shelter 300.
The deck lid deck 200 covers a predetermined area of the upper surface of the main deck 100. The pod 300 is positioned on the leeward side of the box deck 200. The pod 300 includes a windward pod 310 and a wind-away pod 320. The top surface of the shelter 320 is the same height as the top surface of the deck lid deck 200, and the cross-sectional area of the shelter 320 is configured to be slightly smaller than the cross-sectional area of the deck lid deck 200. The windward compartment 310 is located above the wind shelter 320 and has a cross-sectional width that is less than the cross-sectional width of the box cover deck 200.
Referring to fig. 3, the box cover deck 200 has a trapezoidal cross section, and the shelter 320 includes a two-deck structure, each having a rectangular cross section. The vertex of each rectangle intersects the sides of the trapezoid.
Fig. 4 is a schematic structural view of another deck combination according to an embodiment of the present application. Referring to fig. 4, in this embodiment, the box cover deck 200 is rectangular in cross section and the shelter 320 comprises a two-deck structure, each of which is rectangular in cross section. The cross-sectional area of the multi-deck structure is the same as the cross-sectional area of the tank cap deck 200. I.e. the cross-sectional area of the shelter 320 just covers the cross-sectional area of the tank cover deck 200.
In the implementation process of the scheme, the cabin is divided into two parts, namely the wind shelter 320 and the windward shelter 310. Wherein the wind shelter 320 is at the same height as the case cover deck 200, and the windward shelter 310 is protruding from the case cover deck 200. Wherein the wind shelter 320 is arranged with one or more layers of shelter (two layers of shelter as shown in fig. 3 or 4) between the cover deck 200 and the main deck 100, and a multi-layer shelter structure is arranged above the cover deck 200. As shown in fig. 3, the structural width of the wind shelter 320 decreases from bottom to top. The cabin width below the box deck 200 is as large as possible, the design purpose of which is to cover the cross-sectional area of the wind shelter 320 as much as possible, i.e. to make the cabin area of the wind shelter 320 as large as possible. The cabin area of the windward cabin 310 can be reduced accordingly under the design requirement of having the same cabin area as the conventional cabin structure (shown in fig. 1). The width of the cross section of the windward compartment 310 can be reduced accordingly.
Since the wind-shelter 320 is located on the leeward side of the case cover deck 200 and has a cross-sectional area equal to or smaller than that of the case cover deck 200, the windward area of the wind-shelter 320 is negligible to the shelter, and thus the windward area of the wind-shelter 310 is the total windward area of the shelter structure. Because the width of the cross section of the windward cabin 310 can be correspondingly reduced in the application, the total windward area is correspondingly reduced, so that the wind resistance can be reduced, the energy consumption is reduced, and the ship-shaped scheme is lower in carbon and environment-friendly.
In one embodiment, the windward cabin 310 comprises a multi-deck cabin structure, each of which has the same cross-sectional area and cross-sectional width. In one embodiment, the height of each deck structure of windward compartment 310 is less than the height of the compartment structure in wind shelter 320. It should be noted that the number of floors of the windward cabin 310 in the present application needs to be determined according to the total area of the cabin. Compared with the traditional cabin structure, under the condition of having the same cabin area, the lower part volume of the cabin in this application increases, and well upper portion volume reduces, and cabin overall structure's focus moves down, can improve stability and the security of boats and ships.
In one embodiment, the deck assembly further comprises a pilot deck 400, see fig. 3 or 4, the pilot deck 400 being mounted on top of the shelter, and the pilot deck 400 being supported by a support structure 500, the support structure 500 being fixed to the main deck 100. The transverse width of the pilot deck 400 is the same as the transverse width of the main deck 100, and the support structure 500 is near the outer edge of the main deck 100. The support structure 500 adopts a cylindrical steel pipe structure to reduce its wind resistance coefficient.
In one embodiment, the deck assembly further includes a reinforcing rib 600, the bottom end of the reinforcing rib 600 being fixed to the side wall of the cabin, and the top end being connected to the driving deck 400 to support the driving deck 400, making the driving deck 400 more firm.
According to another aspect of the present application there is also provided a vessel comprising a deck assembly as described above.
The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
