Description

Technical Field

[0001] The invention relates to the technical field of ships, and in particular to an asymmetric split deckhouse design structure for a compass deck of an ocean-going rescue ship. Background Art

[0002] Ocean-going rescue ships are mainly responsible for life-saving and ship-saving missions in the open sea, and have a heavy responsibility. Chimneys or other equipment are usually required to be arranged on the compass deck of the rescue ship. The design of the deckhouse is related to the number of ship outfitting, the arrangement of radar masts on the compass deck, and the arrangement of fire monitors.

[0003] Currently, the compass deck deckhouse of ocean-going rescue ships usually has two types: integral type and symmetrical split type.

[0004] The integral deckhouse includes an integral outer shell, which usually contains cabins such as auxiliary equipment rooms. A radar mast is set on the integral outer shell. The width of the integral outer shell is the width of the deckhouse. The integral deckhouse has the following disadvantages: the width of the integral deckhouse exceeds 1 / 4 of the ship's width, so the deckhouse needs to be included in the outfitting number, which will cause the outfitting number to increase by one level. The anchor and mooring equipment needs to be selected according to the increased outfitting number, which makes the rescue ship configuration uneconomical and increases the weight of the anchor and mooring equipment. The center of gravity of these equipment is often high, which increases the center of gravity height of the ship and reduces the stability of the rescue ship.

[0005] Symmetrical split compass deck deckhouses are usually used for ocean-going rescue ships with double chimneys. The two deckhouses are regular in shape considering the internal exhaust pipe layout, and the two deckhouses are far apart, with the radar mast located between the deckhouses. Symmetrical split deckhouses have the following disadvantages: For ships with asymmetrical chimney arrangements, such as single-chimney ships, the space requirements of the left and right deckhouses are often different. Designing in a symmetrical style is likely to cause space waste. There is also a risk that the deckhouse will be included in the outfitting number, and the adaptability is poor. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide an asymmetric split deckhouse design structure for the compass deck of an ocean-going rescue ship.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] An asymmetric split deckhouse design structure for a compass deck of an ocean-going rescue ship, wherein a left deckhouse and a right deckhouse are fixedly arranged on the compass deck, the left deckhouse and the right deckhouse are respectively located on both sides of the midship line, the width of the left deckhouse is different from the width of the right deckhouse, and the sum of the width of the left deckhouse and the width of the right deckhouse is not greater than one-fourth of the ship width of the ocean-going rescue ship; the distance from the midship line to the left deckhouse is different from the distance from the midship line to the right deckhouse; the bow end wall of the left deckhouse is distributed obliquely downward from the stern to the bow; the bow end wall of the right deckhouse is distributed obliquely downward from the stern to the bow; a platform deck is arranged above the compass deck, and the platform deck connects the top of the left deckhouse and the top of the right deckhouse; a radar mast and a fire monitor are fixedly arranged on the platform deck.

[0023] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an asymmetric split deckhouse design structure for the compass deck of an ocean-going rescue ship, a left deckhouse 20 and a right deckhouse 30 are fixed on the compass deck 10, the left deckhouse 20 and the right deckhouse 30 are respectively located on both sides of the midship line 40, the width W1 of the left deckhouse 20 is different from the width W2 of the right deckhouse 30, and the sum of the widths of the left deckhouse 20 and the right deckhouse 30 is not greater than one-fourth of the ship width of the ocean-going rescue ship. The distance L1 from the midship line 40 to the left deckhouse is different from the distance L2 from the midship line 40 to the right deckhouse.

[0025] The bow end wall 21 of the left deckhouse 20 is distributed obliquely downward from the stern to the bow. The end wall 23 where the left side end wall 22 of the left deckhouse 20 and the bow end wall 21 of the left deckhouse 20 are connected is an arc. The end wall 25 where the right side end wall 24 of the left deckhouse 20 and the bow end wall 21 of the left deckhouse 20 are connected is an arc.

[0026] The bow end wall 31 of the right deckhouse 30 is distributed obliquely downward from the stern to the bow. The end wall 33 where the left end wall 32 of the right deckhouse 30 and the bow end wall 31 of the right deckhouse 30 are connected is an arc. The end wall 35 where the right end wall 34 of the right deckhouse 30 and the bow end wall 31 of the right deckhouse 30 are connected is an arc.

[0027] A platform deck 50 is provided above the compass deck 10, and the platform deck communicates the top of the left deckhouse 20 and the top of the right deckhouse 30. Both ends of the platform deck extend to the outside of the top of the left deckhouse and the outside of the top of the right deckhouse, respectively.

[0028] A radar mast 51 is fixedly arranged on the platform deck 50. The midship line is the symmetry center line of the radar mast, and the bottom of the radar mast is fixedly connected to the top of the left deckhouse 20 and the top of the right deckhouse 30 respectively.

[0029] A fire monitor 52 is fixedly provided on the platform deck 50. The fire monitor 52 is arranged at the left end or the right end of the platform deck. There are two fire monitors, one of which is arranged at the left end of the platform deck and the other is arranged at the right end of the platform deck. The two fire monitors are respectively located outside the left deckhouse and outside the right deckhouse.

[0030] The asymmetric split deckhouse design structure of the present invention can be used for ocean-going rescue ships with a single chimney.

[0031] Compared with the integral deckhouse, the split deckhouse of the present invention has a smaller total width, which is less than 1 / 4 of the ship width. It will not increase the outfitting number and anchor and mooring equipment configuration of the rescue ship, will not lead to an increase in the outfitting number, and will not cause the anchor and mooring equipment to jump gear.

[0032] Compared with the symmetrical split deckhouse, the present invention has the following improvements: 1. The asymmetrical type is adopted, and the lateral width of the deckhouses on both sides is flexibly adjusted within the range that the total width of the split deckhouse does not exceed 1 / 4 of the ship width, so as to optimize the layout. 2. The shape adopts a streamlined shape design, which reduces the wind resistance of the rescue ship when sailing at high speed. 3. The deckhouses of the present invention are closer in distance, and the radar mast can be arranged on the top of the deckhouse in a coordinated manner. The stiffness of the radar mast is better than that directly arranged on the compass deck.

[0033] Compared with the prior art, the present invention has the following advantages:

[0034] 1. No increase in outfitting number, no need to increase the number of anchor and mooring equipment. The existing compass deck integral deckhouse takes into account the effective support of the top radar mast, and the width is often greater than 1 / 4 of the ship width. The deckhouse will be included in the outfitting number, resulting in an increase in the number of anchor and mooring equipment. It is estimated that the diameter of the anchor chain will increase from 36mm to 38mm, and the weight of the whole ship will increase by about 4 tons. The present invention adopts a split deckhouse with a total width less than 1 / 4 of the ship width, and will not increase the number of outfitting, which is conducive to reducing the weight and center of gravity height of the rescue ship, increasing the stability of the rescue ship, and improving the safety and reliability of performing rescue missions.

[0035] 2. The size of the deckhouse can be flexibly adjusted according to the layout requirements of the left and right deckhouses, and can be adapted to ships with asymmetrical layouts, such as rescue ships with a single chimney.

[0036] 3. Lower sailing wind resistance: The deckhouse of the present invention adopts a streamlined design to reduce sailing wind resistance.

[0037] 4. The integrated design of the split deckhouse and the radar mast improves the stiffness of the radar mast and simplifies the layout of the compass deck. The radar mast of the existing offshore rescue ship is directly arranged on the compass deck. The radar mast is relatively high, and the cost of meeting the stiffness and strength requirements is relatively high. The layout of the compass deck is also relatively complicated. The present invention uses the split deckhouse as the base of the radar mast, which increases the stiffness of the radar mast and also makes the layout of the compass deck more concise.

[0038] 5. The top can be used to set up a fire monitor platform, which can reduce the vibration of the ship during external firefighting operations, and raise the height of the fire monitor to increase the external firefighting effect.

[0039] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
