The installation and effectiveness of the icebreaker's structure play a key role in this research. Therefore, existing research icebreakers, in order to combine icebreaking and acoustic equipment installation, typically employ a box-shaped keel along the bow of the hull, running the length of the icebreaker.

[0083] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0084] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0085] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0086] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0087] This invention provides ships, such as Figure 1 As shown, the vessel includes a hull and a box-shaped keel 1 installed on the bottom wall of the hull. Along the length of the hull, the box-shaped keel 1 is located near the bow of the hull. By installing the box-shaped keel 1 on the bottom wall of the hull, the box-shaped keel 1 has both good icebreaking function and can also be equipped with acoustic devices, facilitating underwater exploration.

[0088] The present invention also provides a ship construction method for constructing the aforementioned ship body and box-type keel 1. This shipbuilding method ensures the integrity of the sections, facilitating the segmented construction of the icebreaking keel structure 11, the first outer plate structure 2, and the second outer plate structure 3. It allows for the earlier outfitting and painting of the box-type keel 1, as well as the first and second outer plate structures 2 and 3, effectively shortening the ship's docking time and reducing construction costs. Secondly, during segmented construction, only the first outer plate structure 2 needs to be turned over once, reducing the number of turning operations during segmented construction. During the assembly process, only the second assembly structure 5, formed by assembling and welding the acoustic equipment, loading section keel structure 12, and the second outer plate structure 3, needs to be turned over once, further shortening the ship's docking time and reducing construction costs. Thirdly, the segmented construction process reduces overhead welding operations, lowers the difficulty of segmented construction, and improves the efficiency of segmented construction, further shortening the ship's docking time and reducing construction costs.

[0089] The ship construction method includes a sequential construction division method, a segmented construction method, and a sectional assembly method.

[0090] Specifically, such as Figure 1 As shown, the construction division methods include:

[0091] The box-type keel 1 is divided into an icebreaking section keel structure 11 and a loading section keel structure 12. Along the length of the ship body, the icebreaking section keel structure 11 is closer to the bow of the ship body than the loading section keel structure 12.

[0092] Along the height direction of the ship body, the part of the ship body above the box-shaped keel 1 is divided into a first outer plate structure 2 and a second outer plate structure 3. The first outer plate structure 2 is distributed above the icebreaking section keel structure 11, and the second outer plate structure 3 is distributed above the loading section keel structure 12.

[0093] By dividing the box keel 1 into an icebreaking section keel structure 11 and a loading section keel structure 12, and dividing the portion of the ship body above the box keel 1 into a first outer plating structure 2 and a second outer plating structure 3, the integrity of the sections is ensured, facilitating the later segmented construction of the icebreaking section keel structure 11, the first outer plating structure 2, and the second outer plating structure 3. Here, outfitting refers to shipbuilding technology that organically combines the three different types of operations: shipbuilding, outfitting, and painting. Therefore, by adopting the above construction division method, the outfitting process of the box keel 1 can be advanced, as can the outfitting processes of the first outer plating structure 2 and the second outer plating structure 3, thereby shortening the ship's docking period and reducing the ship's construction cost.

[0094] Specifically, such as Figures 1-9 As shown, the segmented construction and assembly method includes:

[0095] S100, The icebreaking section keel structure 11 is constructed in segments.

[0096] Specifically, such as Figure 1 and Figure 2 As shown, the specific steps for constructing the icebreaking section keel structure 11 in segments include:

[0097] S110, The icebreaking section keel structure 11 is divided into the icebreaking section bottom plate 111 and two side structures 112.

[0098] Specifically, since the icebreaking section keel structure 11 is mainly used for icebreaking and no acoustic equipment is installed on it, the icebreaking section keel structure 11 is divided into an icebreaking section bottom plate 111 and two side structures 112, which facilitates subsequent assembly and welding to form a spindle-shaped icebreaking section keel structure 11.

[0099] S120. Assemble the icebreaking section bottom plate 111; assemble the two side structures 112 respectively.

[0100] It is understandable that assembling the icebreaking section bottom plate 111 is preferably carried out simultaneously with assembling the two side structures 112. This can further shorten the ship's docking time.

[0101] S130, the bottom plate 111 of the ice-breaking section is installed on the first jig, so that the inner bottom wall of the bottom plate 111 of the ice-breaking section faces upward.

[0102] Specifically, by setting the inner bottom wall of the icebreaking section bottom plate 111 to face upwards, it is easier to assemble and weld the two side structures 112 to the icebreaking section bottom plate 111 in subsequent processes, avoiding welding operations by welders working overhead, and improving welding efficiency and welding quality.

[0103] Specifically, the first frame is prefabricated. This can further shorten the ship's docking time.

[0104] S140, hoist one of its side structures 112, assemble it, and weld it to the bottom plate 111 of the icebreaking section.

[0105] S150, hoist the other side structure 112, assemble and weld it to the icebreaking section bottom plate 111, so that the icebreaking section bottom plate 111 and the two side structures 112 form a spindle-shaped icebreaking section keel structure 11.

[0106] Therefore, by using the above method to construct the icebreaking section keel structure 11 in sections, the welding personnel are spared from overhead welding operations, and the efficiency of constructing the icebreaking section keel structure 11 in sections is effectively improved, further shortening the ship's docking period.

[0107] S200, The first outer panel structure 2 is constructed in segments.

[0108] Specifically, such as Figures 1-4 As shown, the specific steps for constructing the first outer plate structure 2 in segments include:

[0109] S210, Divide the first outer plate structure 2 into a first deck 21, two first sub-outer plate structures 22, a first support structure 23, and two cylindrical structures 24.

[0110] S220, the first support structure 23 is divided into at least a first longitudinal bone, a plurality of first transverse components and a plurality of first longitudinal components.

[0111] Specifically, steps S210 and S220 can be performed simultaneously or in a different order. In this embodiment, steps S210 and S220 are preferably performed sequentially.

[0112] Among them, there are differences in the structure of multiple first transverse components; there are differences in the structure of multiple first longitudinal components.

[0113] S230. Assemble the first deck 21; construct the two first sub-outer plate pieces 22 in sequence.

[0114] Preferably, the first deck 21 is assembled and formed simultaneously with the sequential construction of the two first sub-outer plate sections 22. This can further shorten the ship's docking time.

[0115] Specifically, such as Figure 4 As shown, the specific steps for constructing the first sub-outer plate 22 segments include:

[0116] The first sub-outer plate 22 is divided into a first outer plate 221 and multiple first ribs 222. The structures of the multiple first ribs 222 are different.

[0117] The first outer plate 221 is placed on the fourth frame such that the inner sidewall of the first outer plate 221 faces upward.

[0118] Multiple first skeleton members 222 are hoisted in sequence, assembled, and welded to the first outer plate 221.

[0119] By setting the inner wall of the first outer plate 221 to face upward, it is convenient to assemble and weld multiple first skeletons 222 to the first outer plate 221 in sequence, avoiding the need for welding personnel to perform overhead welding operations, improving welding efficiency and welding quality, and also improving the efficiency of segmented construction of the first sub-outer plate 22.

[0120] The fourth frame is prefabricated, which can further shorten the ship's docking time.

[0121] S240, the first deck 21 is hoisted onto the second jig so that the reverse side of the first deck 21 faces upward.

[0122] This setup facilitates the subsequent welding of the first longitudinal skeleton, multiple first longitudinal components, and multiple first transverse components, further reducing overhead welding operations, improving welding efficiency and quality, and further shortening the ship's docking period.

[0123] S250, the first longitudinal skeleton is hoisted, assembled, and welded to the first deck 21.

[0124] S260. Multiple first longitudinal components and multiple first transverse components are hoisted in a first predetermined sequence, assembled, and welded to the first longitudinal frame and / or the first deck 21.

[0125] Specifically, the first setting order is the optimal order in which the first longitudinal rib, multiple first longitudinal components, and multiple first transverse components form the first support structure 23 on the first deck 21. It can be understood that the first setting order is different for the first support structure 23 with different compositions.

[0126] S270, hoist one of the first sub-outer plate pieces 22, assemble and weld it to the first deck 21 and the first support structure 23.

[0127] S280, hoist another first sub-outer plate 22, assemble and weld it to the first deck 21 and the first support structure 23.

[0128] S290, hoist one of its cylindrical structures 24, assemble and weld it to one of its first sub-outer plate 22 and first support structure 23;

[0129] S291. Hoist another cylindrical structure 24, assemble and weld it to another first sub-outer plate 22 and the first support structure 23, so that the two cylindrical structures 24 are connected and communicate with the outside.

[0130] S293. Weld the joint of the two cylindrical structures 24. This creates a through channel connecting the two cylindrical structures 24 to the outside. The cylindrical structure 24 houses the propeller, forming the bow thruster structure of the ship and assisting in the ship's steering.

[0131] Therefore, by using the above method to construct the first outer plate structure 2 in sections, the welding personnel are spared from overhead welding operations, and the efficiency of constructing the icebreaking section keel structure 11 in sections is further improved, thus further shortening the ship's docking period.

[0132] S300, such as Figure 2 As shown, the first outer plate structure 2 is assembled and welded to the icebreaking section keel structure 11 to form the first assembly structure 4.

[0133] Specifically, the specific steps for assembling and welding the first outer plate structure 2 to the icebreaking section keel structure 11 to form the first assembly structure 4 include:

[0134] S310, the hoisting ice-breaking section keel structure 11 is set on the third frame.

[0135] Specifically, the third frame is prefabricated. This can further shorten the ship's docking time.

[0136] S320. The first outer plate structure 2 is hoisted and flipped so that the front of the first deck 21 faces upward.

[0137] It is understandable that the two side structures 112 of the icebreaking section keel structure 11 assembled in step S100 are both located above the icebreaking section bottom plate 111. Therefore, by hoisting and flipping the first outer plate structure 2 so that the front of the first deck 21 faces upward, when the first outer plate structure 2 is hoisted directly above the icebreaking section keel structure 11, it can be ensured that the two first sub-outer plate pieces 22 and the two side structures 112 are connected in a one-to-one correspondence. This facilitates the assembly and welding of the first outer plate structure 2 to the icebreaking section keel structure 11, effectively reducing the welding difficulty of welding the first outer plate structure 2 to the icebreaking section keel structure 11 to form the first assembly structure 4, and improving the welding quality.

[0138] S330. The first outer plate structure 2 is hoisted directly above the icebreaking section keel structure 11, so that the two first sub-outer plate structures 22 and the two side structures 112 are connected in a one-to-one correspondence.

[0139] S340. The first outer plate structure 2 is welded to the icebreaking section keel structure 11 to form the first assembly structure 4.

[0140] S400, The second outer panel structure 3 is constructed in sections.

[0141] like Figures 5-8 As shown, the specific steps for constructing the second outer plate structure 3 in segments include:

[0142] S410, the second outer plate structure 3 is divided into a second deck 31, two second sub-outer plate pieces 32, and two third sub-outer plate pieces 33. Among them, the second sub-outer plate pieces 32 are closer to the first outer plate structure 2 than the third sub-outer plate pieces 33.

[0143] Specifically, along the length of the ship's body, the length of the icebreaking section keel structure 11 is less than the length of the loading section keel structure 12. Therefore, the second outer plating structure 3 is divided into a second deck 31, two second sub-outer plating sections 32, and two third sub-outer plating sections 33, which facilitates the segmented construction of the second sub-outer plating sections 32 and the third sub-outer plating sections 33, thereby further reducing construction difficulty and improving construction efficiency.

[0144] S420. Assemble the second deck 31; construct the two second sub-outer plate pieces 32 in sequence; construct the two third sub-outer plate pieces 33 in sequence.

[0145] Preferably, the assembly of the second deck 31, the sequential construction of the two second sub-outer plating sections 32, and the sequential construction of the two third sub-outer plating sections 33 are carried out simultaneously. This can further shorten the ship's docking time.

[0146] Specifically, such as Figure 6As shown, the specific steps for constructing the second sub-outer plate 32 segments include:

[0147] The second sub-outer plate 32 is divided into a second outer plate 321 and multiple second skeletons 322.

[0148] The second outer plate 321 is placed on the sixth frame such that the inner sidewall of the second outer plate 321 faces upward.

[0149] Multiple second skeleton members 322 are hoisted in sequence, assembled, and welded to the second outer plate 321.

[0150] By setting the inner wall of the second outer plate 321 to face upward, it is convenient to assemble and weld multiple second skeletons 322 to the second outer plate 321 in sequence, avoiding the need for welders to perform overhead welding operations, improving welding efficiency and welding quality, and also improving the efficiency of segmented construction of the second sub-outer plate 32.

[0151] Among them, there are differences in the structure of multiple second bone materials 322.

[0152] Specifically, such as Figure 7 As shown, the specific steps for constructing the third sub-outer plate 33 in segments include:

[0153] The third sub-outer plate 33 is divided into a third outer plate 331 and multiple third skeletons 332.

[0154] The third outer plate 331 is placed on the seventh frame, with the inner sidewall of the third outer plate 331 facing upward.

[0155] Multiple third-grade aggregates 332 are hoisted in sequence, assembled, and welded to the third outer plate 331.

[0156] By setting the inner wall of the third outer plate 331 to face upward, it is convenient to assemble and weld multiple third skeletons 332 to the third outer plate 331 in sequence, avoiding the need for welders to perform overhead welding operations, improving welding efficiency and welding quality, and also improving the efficiency of segmented construction of the third sub-outer plate 33.

[0157] Among them, there are differences in the structure of multiple third-strength materials 332.

[0158] The sixth and seventh frame frames were prefabricated, which further shortens the ship's docking time.

[0159] S430, The second deck 31 is placed on the fifth frame such that the reverse side of the second deck 31 faces upward.

[0160] This configuration facilitates the subsequent assembly and welding of the second sub-outer plate 32 and the third sub-outer plate 33 to the second deck 31, avoiding overhead welding operations for welders, further improving welding efficiency and quality, and also increasing the efficiency of segmented construction of the second outer plate structure 3.

[0161] The fifth and seventh frame frames are prefabricated, which can further shorten the ship's docking time.

[0162] S440, hoist one of the second sub-outer plate panels 32, assemble and weld it to the second deck 31.

[0163] S450, hoist one of the third sub-outer plate pieces 33, assemble and weld it to the second deck 31, and weld one of the second sub-outer plate pieces 32 and one of the third sub-outer plate pieces 33 into shape.

[0164] Steps S440 and S450 allow the outer plate panels of the ship's body to be assembled and formed on one side along the width direction.

[0165] S460, hoist another second sub-outer plate 32, assemble and weld it to the second deck 31.

[0166] S470, hoist another third sub-outer plate 33, assemble and weld it to the second deck 31, and weld another second sub-outer plate 32 and another third sub-outer plate 33 into shape.

[0167] Steps S460 and S470 allow the outer plate panels of the ship's body to be assembled and formed on the other side along the width direction.

[0168] S500, the acoustic equipment, the loading section keel structure 12, and the second outer plate structure 3 are assembled and welded to form the second assembly structure 5.

[0169] Specifically, the specific steps for assembling and welding the acoustic equipment, the loading section keel structure 12, and the second outer plate structure 3 to form the second assembly structure 5 include:

[0170] S510, The loading section keel structure 12 is divided into the loading section bottom plate 121, two side outer plates 122, and a second support structure 123.

[0171] S520, the second support structure 123 is divided into at least a second longitudinal bone, a plurality of second transverse components and a plurality of second longitudinal components.

[0172] Among them, there are differences in the structure of multiple second transverse components; there are differences in the structure of multiple second longitudinal components.

[0173] S530, hoist one of its side outer plates 122, assemble and weld it to one of its second sub-outer plate pieces 32 and one of its third sub-outer plate pieces 33.

[0174] S540, hoist another side outer plate 122, assemble and weld it to another second sub-outer plate 32 and another third sub-outer plate 33.

[0175] S550, the second longitudinal skeleton is hoisted, assembled, and welded to the second deck 31.

[0176] S560, hoisting multiple second longitudinal components and multiple second transverse components in a second predetermined sequence, assembling and welding them to the second longitudinal rib and / or the side outer plate 122.

[0177] Specifically, the second arrangement order is the optimal sequence in which multiple second longitudinal components and multiple second transverse components are connected to the second longitudinal rib and / or the side outer plate 122 to form the second support structure 123. It is understood that the second arrangement order is different for different compositions of the second support structure 123.

[0178] S570, the hoisting acoustic equipment is assembled on the loading section keel structure 12.

[0179] S580, the bottom plate 121 of the hoisting and loading section is assembled and welded to the two side outer plates 122 and the second support structure 123.

[0180] Understandably, since the acoustic equipment needs to be assembled onto the loading section keel structure 12, during the assembly and welding of the acoustic equipment, the loading section keel structure 12, and the second outer plate structure 3, the loading section bottom plate 121, the two side outer plates 122, and the second longitudinal rib, multiple second transverse components, and multiple second longitudinal components of the second support structure 123 are assembled onto the second outer plate structure 3 as separate structures in sequence. This ensures that the acoustic equipment can be assembled onto the loading section keel structure 12 while maintaining its structural strength, thus improving the efficiency of assembling the acoustic equipment and the loading section keel structure 12 onto the second outer plate structure 3 and further shortening the ship's docking period.

[0181] S600, the first assembly structure 4 and the second assembly structure 5 are joined and welded together.

[0182] The specific steps for welding the first assembly structure 4 and the second assembly structure 5 together include:

[0183] S610, the first assembly structure 4 is hoisted and installed on the first portal frame.

[0184] S620, the second assembly structure 5 is hoisted and turned over so that the front of the second deck 31 of the second assembly structure 5 faces upward.

[0185] It is understandable that the loading section keel structure 12 of the second assembly structure 5, which is assembled in step S500, is located above the second outer plate structure 3. Therefore, by hoisting the second assembly structure 5 and turning it over, the front of the second deck 31 of the second assembly structure 5 is facing upward, which facilitates the subsequent joining and docking of the second assembly structure 5 and the first assembly structure 4.

[0186] S630, hoist the second assembly structure 5 onto the second portal frame, so that the second assembly structure 5 and the first assembly structure 4 can be joined together.

[0187] S640, The first assembly structure 4 and the second assembly structure 5 are welded together.

[0188] The first and second portal brackets can be general-purpose portal brackets. The goal is to ensure that the second assembly structure 5 and the first assembly structure 4 can be joined and connected.

[0189] Preferably, steps S100, S200, and S400 are performed simultaneously. Step S300 is performed after steps S100 and S200 are completed, step S500 is performed after step S400 is completed, and finally step S600 is performed. This can further improve the shipbuilding efficiency and shorten the ship's docking period. Specifically, in this embodiment, steps S100 to S600 are performed sequentially as an example.

[0190] After each welding operation, the welded area must be inspected to ensure the quality of the weld.

[0191] After each of the first, second, third, fourth, fifth, sixth, and seventh jigs is completed, the jig must undergo quality inspection to ensure its performance and thus improve the quality of the ship built later.

[0192] Specifically, after completing step S100, the icebreaking keel structure 11, constructed in sections, needs to undergo quality inspection; after completing step S200, the first outer plate structure 2, constructed in sections, needs to undergo quality inspection; after completing step S300, the first assembly structure 4 needs to undergo quality inspection; after completing step S400, the second outer plate structure 3, constructed in sections, needs to undergo quality inspection; and after completing step S500, the second assembly structure 5 needs to undergo quality inspection. This further improves the quality of the ship constructed in the later stages.

[0193] Therefore, this shipbuilding method can effectively improve the quality of the constructed ships, increase the efficiency of shipbuilding, shorten the ship's docking time, and reduce the shipbuilding cost.
