Abstract

The invention discloses a ship bow deck and a ship, wherein the outer plate of the bow deck is designed in an outward-floating mode, so that the line shape of the outer plate of the bow is optimized, the area of the deck is enlarged, and the arrangement requirement of mooring equipment is met. Because the outward floating deck is far away from the waterline, the resistance generated by the outward floating of the deck is very small when the ship runs normally, and the normal sailing of the ship is not influenced. The outer deck, the inner structure and the outer plate form an integral frame, so that the area of the deck is effectively increased, and meanwhile, the structural strength is ensured to meet the specification requirement.

The purpose of the present invention is achieved through the following technical solutions, a bow deck of a ship, including a mooring deck and an outer plate, wherein the outer plate is in the form of a floating outer plate, and the edge of the mooring deck is enlarged, and is corner-jointed with the outer plate of an outer floating shape .

There is a strengthening structure between the floating outer plate and the mooring deck.

The floating outer plate is arranged above the waterline of the bow deck.

Preferably, the floating outer plate is set above the waterline of the bow deck, within the height range of (1/7-1/5) B below the main deck of the bow, and not greater than H/2, where B is the original mooring Deck width, H is the height from the draft to the mooring deck, and the width of the floating deck area is 0.2 times the original mooring deck width.

Preferably, a plurality of through holes are arranged at equal intervals on the longitudinals of the mooring deck and the outer plate, and the through holes on the longitudinals of the mooring deck correspond to the through holes on the longitudinals of the outer plate, The supplementary plates are arranged at the through holes of the longitudinal bones, and the two corresponding supplementary plates are connected by reinforcing ribs to form a reinforced structure.

Preferably, a reinforcing bracket is provided at the end where the mooring deck is connected to the outer shell plate.

Preferably, a plurality of holes are arranged on the outer panel of the outer shell.

Preferably, a watertight wall is provided inside the area where the flared outer plate is connected to the mooring deck.

In addition to providing a ship's bow deck, the present invention further provides a ship using the above-mentioned ship's bow deck.

Compared with the prior art, the present invention has the following advantages:

The bow deck of a ship and the ship provided by the present invention can optimize the line shape of the bow outer plate and increase the area of the deck by designing the outer plate of the bow deck to meet the requirements of the layout of mooring equipment. . Since the floating deck is set far away from the waterline, the resistance caused by the floating deck during normal operation of the ship is very small and does not affect the normal navigation of the ship. The floating deck forms an integral frame with the internal structure and the outer plate, which effectively increases the deck area while ensuring that the structural strength meets the specification requirements.

Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

As shown in Figures 2 to 3, the technical solution of the present invention provides a bow deck of a ship, including a mooring deck and an outer plate, wherein the outer plate is in the form of floating, with smooth lines, and the edge of the mooring deck is enlarged , and the corner connection with the outer floating-shaped outer plate.

There is a strengthening structure between the floating outer plate and the mooring deck.

The floating outer plate is set above the waterline of the bow deck.

In a preferred embodiment of the present invention, the flared outer plate is arranged above the waterline of the bow deck and within the height range of (1/7-1/5) B below the main deck of the bow, and not greater than H/2, where , B is the width of the original mooring deck, H is the height from the draft to the mooring deck, and the width of the floating deck area is 0.2 times the width of the original mooring deck. In this embodiment, the floating area of the outer plate is far away from the waterline, which can reduce the slapping pressure on the floating area when the ship is in operation.

As shown in Figure 4, in a preferred embodiment of the present invention, there are a plurality of through holes at equal intervals on the longitudinals of the mooring deck and the outer plate, and the through holes on the longitudinals of the mooring deck are aligned with the outer plates. The through-holes on the longitudinals of the outer plates correspond to each other, and the through-holes of the longitudinals are provided with patching plates, and the two corresponding patching plates are connected by reinforcing ribs to form a reinforced structure. Reinforced brackets are provided at the end where the mooring deck is connected to the outer shell plating. In this embodiment, the reinforced structure can improve the structural strength of the overall floating area and resist the slapping of seawater. Lightening holes are provided in the reinforced structure to facilitate the entry and exit of personnel during segmental reverse construction, and facilitate the entry of seawater into the buffer cabin during navigation. Back and forth circulation.

As shown in Fig. 5 to Fig. 6, in another preferred embodiment of the present invention, a plurality of holes are provided on the outer panel of the outer float. A watertight wall is arranged inside the area where the floating outer plate is connected with the mooring deck.
