Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a split-molding integrated hull structure. Background Technology

[0002] In shipbuilding, vessels are classified into large ships and small vessels based on their hull size. Small vessels include small fishing boats and yachts. Integrated hulls are a structural form in shipbuilding, referring to the use of an integral design and construction for the main body of the hull, reducing the number of sections and even achieving seamless construction. Through advanced technology, the hull structure is integrated into a whole, which has advantages such as high structural strength, good sealing, and low sailing resistance. It can improve the stability, safety, and sailing efficiency of ships and is widely used in high-performance ships and other fields.

[0003] However, when semi-finished hulls are assembled, the joints are mostly joined by welding. The tensile and shear strength is provided by the strength of the weld itself. The internal structural load-bearing capacity of the hull mainly depends on the synergy between the keel and the connecting flanges. At the same time, most of the splicing processes now require repeated manual correction and alignment, resulting in low splicing efficiency. Furthermore, after the splicing is completed, the joints are prone to shifting due to external forces such as vibration during the welding process, affecting the splicing effect.

[0004] Therefore, we provide a semi-molded integrated hull structure to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A semi-molded integrated hull structure includes a left hull and a right hull. Semi-molded hull splicing components are provided on the inner sides of the left and right hulls. Each semi-molded hull splicing component includes a left hull splicing keel welded to the inner side of the left hull and a right hull splicing keel welded to the inner side of the right hull. A left hull connecting flange is provided in the middle of each left hull splicing keel, and a right hull connecting flange is provided in the middle of each right hull splicing keel. A trapezoidal insert is welded to the bottom inner side of each left hull, and a trapezoidal groove is welded to the bottom inner side of each right hull.

[0007] As a further description of the above technical solution:

[0008] The right and left halves of the hull are symmetrically arranged, and both halves are made of carbon fiber composite material and coated with polyurethane anti-corrosion paint.

[0009] As a further description of the above technical solution:

[0010] An injection groove is provided at the joint between the left and right halves of the hull. The injection groove is filled with a sealant, which is a two-component polyurethane sealant.

[0011] As a further description of the above technical solution:

[0012] The right hull splicing keel and the left hull splicing keel are connected by a slot and fixed by rivets. The right hull splicing keel and the left hull splicing keel are arranged symmetrically in two groups.

[0013] As a further description of the above technical solution:

[0014] Both the left and right ship connecting flanges are welded to the left and right halves of the hull, respectively, and are arranged in three equidistant groups. The left and right ship connecting flanges are connected by rivets.

[0015] As a further description of the above technical solution:

[0016] The trapezoidal slots and trapezoidal blocks are connected by a slot, and there is a one-to-one correspondence between the trapezoidal slots and trapezoidal blocks. The trapezoidal slots and trapezoidal blocks are arranged in three groups at equal distances.

[0017] As a further description of the above technical solution:

[0018] Each trapezoidal insert has a limiting bolt groove in the middle, and each trapezoidal insert has a connecting bolt plate in the middle. The limiting bolt groove and the connecting bolt plate are connected by a slot and are connected by rivets.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. This utility model uses a semi-formed hull splicing component to integrally press the hull, keel, and flanges through a split-forming method, which can effectively improve production efficiency and hull strength. The right hull splicing keel and the left hull splicing keel can be interlocked through slots and fixed by rivets, achieving fast and precise docking. It also improves the overall connection strength and structural stability of the left and right hull halves. When the left and right hull halves are aligned and spliced, the three sets of equidistant left and right hull connecting flanges are synchronously docked and connected by high-strength rivets to form a stable linear support structure, effectively dispersing the torsional and impact loads during navigation.

[0021] 2. This utility model uses a semi-formed hull splicing component. When the left half of the hull is embedded into the right half of the hull from top to bottom, three sets of trapezoidal inserts and trapezoidal grooves are aligned and pressed together in sequence. The wedge-shaped self-locking characteristics are used to achieve lateral positioning, effectively suppressing the deformation and expansion of the splicing gap and enhancing the shear resistance of the joint. As the left and right halves of the hull are spliced, the connecting bolt plate will be embedded in the limiting bolt groove. The two are locked together by the slot and fixed by the rivet, forming a rigid connection point, which improves the longitudinal connection strength and tensile performance.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4As shown, this utility model provides a technical solution: a semi-molded integrated hull structure, including a left half hull 1, a right half hull 2 ​​disposed on the right side of the left half hull 1, and a semi-molded hull splicing assembly 5 disposed on the inner side of the left half hull 1 and the right half hull 2. The semi-molded hull splicing assembly 5 includes a left hull splicing keel 501 welded to the inner side of the left half hull 1, a right hull splicing keel 502 welded to the inner side of the right half hull 2, a left hull connecting flange 503 disposed in the middle of the left hull splicing keel 501, a right hull connecting flange 504 disposed in the middle of the right hull splicing keel 502, a trapezoidal insert 505 welded to the bottom inner side of the left half hull 1, and a trapezoidal groove 506 welded to the bottom inner side of the right half hull 2.

[0029] Furthermore, the right half of the hull 2 ​​and the left half of the hull 1 are symmetrically arranged. Both the right half of the hull 2 ​​and the left half of the hull 1 are made of carbon fiber composite material and coated with polyurethane anti-corrosion paint. When needed, the right half of the hull 2 ​​and the left half of the hull 1 are assembled together. Due to the use of carbon fiber composite material and the polyurethane anti-corrosion paint on the outer surface, the corrosion resistance and overall strength of the hull can be effectively improved, and the service life can be extended. Moreover, by molding in half, the hull, keel and flange are pressed together as a whole, which can effectively improve production efficiency and hull strength.

[0030] Furthermore, the trapezoidal groove 506 and the trapezoidal block 505 are connected by a slot, and the trapezoidal groove 506 and the trapezoidal block 505 correspond one-to-one. The trapezoidal groove 506 and the trapezoidal block 505 are arranged in three sets at equal distances. When it is needed, when the left half of the hull 1 is inserted into the right half of the hull 2 ​​from top to bottom, the three sets of trapezoidal blocks 505 and trapezoidal grooves 506 are aligned and pressed together in sequence. The wedge-shaped self-locking characteristic is used to achieve lateral positioning, effectively suppress the deformation expansion of the splicing gap, and enhance the shear resistance of the joint.

[0031] Furthermore, each trapezoidal insert 505 is provided with a limiting bolt groove 507 in the middle, and each trapezoidal insert 506 is provided with a connecting bolt plate 508 in the middle. The limiting bolt groove 507 and the connecting bolt plate 508 are connected by a slot and are connected by rivets. When needed, as the left half of the hull 1 and the right half of the hull 2 ​​are spliced, the connecting bolt plate 508 will be embedded in the limiting bolt groove 507. The two are locked together by the slot and fixed by the rivet, forming a rigid connection point, which improves the longitudinal connection strength and tensile performance.

[0032] Furthermore, the right hull keel 502 and the left hull keel 501 are connected by a slot and fixed by rivets. The right hull keel 502 and the left hull keel 501 are arranged symmetrically in two sets. When needed, the right hull keel 502 and the left hull keel 501 can be interlocked by the slot and fixed by the rivets, achieving quick and precise docking and improving the overall connection strength and structural stability of the left half hull 1 and the right half hull 2.

[0033] Furthermore, both the left hull connecting flange 503 and the right hull connecting flange 504 are welded to the left half hull 1 and the right half hull 2, and the left hull connecting flange 503 and the right hull connecting flange 504 are arranged in three sets at equal distances. The left hull connecting flange 503 and the right hull connecting flange 504 are connected by rivets. When the left half hull 1 and the right half hull 2 ​​are aligned and spliced, the three sets of equidistant left hull connecting flanges 503 and right hull connecting flanges 504 are simultaneously connected and connected by high-strength rivets to form a stable linear support structure, effectively dispersing the torque and impact loads during navigation.

[0034] Furthermore, an injection groove 3 is provided at the joint between the left half hull 1 and the right half hull 2. The injection groove 3 is filled with a sealant 4, which is a two-component polyurethane sealant. After the left half hull 1 and the right half hull 2 ​​are spliced ​​and fixed, the injection grooves 3 inside the joint of the left half hull 1 and the right half hull 2 ​​are aligned to form a closed cavity. At this time, the sealant 4 of the two-component polyurethane sealant is injected into the injection groove 3 to fully fill the splicing gap. After curing, a high-strength waterproof sealing layer is formed, which effectively prevents water from seeping in, improves the durability and integrity of the connection, and relieves stress concentration, ensuring the structural stability and safety of the hull in complex water environments.

[0035] Working principle: When needed, the left half of the hull 1 is assembled with the right half of the hull 2 ​​from top to bottom. During this process, the trapezoidal insert 505 is embedded in the trapezoidal groove 506, and the connecting bolt plate 508 is embedded in the limiting bolt groove 507. Then, the connecting bolt plate 508 and the limiting bolt groove 507 are fixed together with rivets. At this time, the trapezoidal insert 505 and the limiting bolt groove 507 limit the lateral and longitudinal tensile forces respectively, preventing dislocation during the assembly process and improving the bottom's impact and vibration resistance. After being fixed, the left hull connecting flange 503 and the right hull connecting flange 504 are aligned, and the left hull splicing keel 501 and the right hull splicing keel 502 are also aligned and fitted together. At this time, the left hull splicing keel 501 and the right hull splicing keel 502 are welded together as one piece, and rivets are used for riveting to form a double-reinforced structure. Finally, the sealing colloid 4 is injected into the injection groove 3 to seal the splice. This completes the process of using a semi-molded integrated hull structure.
