[0001] The invention relates to the field of cable structures, in particular to a cable penetration and structural reinforcement structure and a ship thereof. Background technology:

[0002] During the design and construction of ships, when cables and pipelines need to pass through the structure, holes must be opened at the penetration positions.

[0003] In places where tightness is required, when cables pass through, a special penetration piece needs to be installed at the opening so that the dressing can be filled in the penetration to seal the opening. If a large number of cables pass through a certain area at the same time, the corresponding positions need to be opened and reinforced more densely according to the cable route. For many cables, the existing structure has defects in its tightness and structural strength.

[0052] As Figures 1 to 8 shown, in one embodiment, the present invention provides a structure for cable penetration and structural reinforcement. The structure for cable penetration and structural reinforcement includes a main deck 1, flat iron 2 inside the circle, a sealing plate 3, and a through row of holes 4;

[0053] The main deck 1 is provided with a through hole 11;

[0054] The flat iron 2 inside the circle is arranged along the inner edge of the through hole 11, forming a cylindrical structure facing the through hole 11;

[0055] The sealing plate 3 seals the through hole 11;

[0056] The through row of holes 4 is arranged on the sealing plate 3, and the row of holes 41 on the through row of holes 4 penetrates the sealing plate 3.

[0057] In one embodiment, one end of the flat iron 2 inside the circle is flush with the main deck 1, and the other end of the flat iron 2 inside the circle protrudes from the main deck 1;

[0058] The sealing plate 3 is flush with the end face of the other end of the flat iron 2 inside the circle.

[0059] In one embodiment, the through row of holes 4 includes two rows of spaced holes 41;

[0060] Each row of the spaced holes 41 is arranged by a plurality of isolation frames 42 arranged along the length direction, and the isolation frames 42 of each row are formed by enclosing and partitioning with partition plates 43. In the high-stress area where the main deck has a watertight requirement, a large number of cables are concentrated and passed through. After consulting with the electrical installation designers, according to the convenience of their subsequent construction and the restrictions of the bulkheads and longitudinal bulb flats of the structure in the through area before and after, the cables are planned in two rows, and the form and position spacing of the square cable through are planned.

[0061] In one embodiment, the minimum corner of the through hole 11 should be R175.

[0062] In one embodiment, a bulkhead 5 is arranged around the flat iron 2 inside the circle.

[0063] In one embodiment, the thickness of the bulkhead 5 is 35 mm. After the electrical installation cables and through arrangements are completed, holes are opened according to the specification rules and the requirements of the hull structure strength. Different from opening one hole for each through in the conventional way. To improve the design efficiency and space utilization rate, a large hole including all electrical installation throughs is adopted. For the corner of the thick plate opening, to prevent fatigue, the corner rounding needs to be opened to more than 5 times the plate thickness. For example, here, the minimum corner should be R175, and in the actual ship, it generally needs to be more than 50 mm larger than the minimum value, so R225 is opened. At the same time, in order to facilitate the through installation, a certain distance is reserved between the hole edge and the through.

[0064] In one embodiment, a longitudinal girder structure 5 is arranged on the other side of the main deck 1 protruding from the flat iron 2 inside the circle, and the longitudinal girder structure surrounds the through hole and is isolated from the through hole 11 by a predetermined width H.

[0065] In one embodiment, a parallel plate 6 is arranged between the longitudinal girder structure 5 and the other end of the main deck 1, and the parallel plate 6 is arranged parallel to the main deck 1.

[0066] In one embodiment, the main deck 1 is made of DH550-Z35. After the hull is perforated, the longitudinal bulb flat bars at the corresponding positions also have to be disconnected. Due to the lack of a certain area of plates in the main hull, the strength is weakened. According to the structural characteristics, a combined structure is formed by adding a ring of panels in the hole to ensure that the plates in the perforated area do not yield and buckle. At the same time, in order to make the truncated bulb flat steel structure reasonable, a new structure needs to be set at the front and rear ends of the hole respectively to provide connection points for the disconnected bulb flat steel. According to the design requirements of the cable, a box structure of a certain height needs to be set here to facilitate the cable to adjust its direction through this place. The penetration height of the electrical installation is actually a certain distance higher than the main deck, so the panel structure inside the perforated circle is raised to the penetration position. There is a gap between the hull structure after perforation and reinforcement and the penetration, and the gap needs to be closed to ensure the deck tightness. Therefore, an additional sealing plate is added inside the panel structure of the circle.

[0067] The formed structural style is as shown in the figure. On the basis of simple structural form and guaranteed strength, the electrical installation design and construction are convenient and the dressing is saved. If the number of penetrations is small and there is only one row of cables, the opening width is significantly reduced, and the penetrator of the electrical installation can be cancelled, and the structural reinforcement ring can be directly used as the cable penetrator.

[0068] After centrally organizing the original scattered opening requirements, a larger opening is used to meet the opening requirements. With an improved strengthening form, while strengthening the structure, the design requirements for the electrical installation cable penetration are met. The structure is enlarged with the smallest and simplest structure, and at the same time, the design requirements of the structure and the electrical installation are met, while taking into account the construction quality, construction efficiency, precision control, and penetration material selection, achieving multiple benefits at one stroke.

[0069] In one embodiment, the present invention also provides a ship with a structure having cable penetration and structural reinforcement, and the ship includes the structure of cable penetration and structural reinforcement described above. This patent has been applied to the 1600-ton wind power installation platform project. In the main hull well area, the connection area between the main crane pedestal and the main deck, the connection position between the chimney and the main deck, and the connection position between the fan room and the main deck, all structural forms have undergone strength calculations and there are no comments in the drawing review. Relying on this design, the corresponding design content of the electrical installation is simple and the form is easy to implement. During the on-site ship verification process, the shipowner, ship inspection and construction departments all gave their recognition.

[0070] Beneficial effects:

[0071] 1. The hull structure itself has a dense structure of stiffening plates, stiffening rings, stiffening ribs, etc. In addition, installing cable penetration on the edge of the opening or inside the stiffening ring is difficult in construction. The precision control requirements for installing cable penetration inside the stiffening ring are high, and the construction quality and efficiency cannot be guaranteed.

[0072] 2. On the high-stress bulkhead plates, such as the main deck in the cofferdam area of a wind power platform, the plate thickness is correspondingly thick. When cables pass through in a concentrated manner, according to the requirements of codes and regulations, the radius of the chamfer of the hole must be large, and the size of the hole thus opened is relatively large. However, only a small area is actually required for cable penetration. The holes dug on the hull structure are dense, making it difficult to meet the requirements of codes and regulations. After the holes are opened, the structure is weakened significantly, and many reinforcing parts are needed. Most of the work in the whole process is useless, and the existing technology is outdated.

[0073] 3. In the high-stress thick-plate bulkhead, where tightness is required, due to the requirements of codes and regulations, the specifications of ordinary cable penetration cannot be properly matched with the hole-opening pattern, which restricts the design and procurement of electrical installation.

[0074] 4. In the high-stress thick-plate bulkhead with large holes and where tightness is required, the corresponding cable penetration size is large, and the volume of the dressing filled inside the penetration increases, wasting the dressing.

[0075] 5. The cable boxes added after the cables on the main deck pass through in a concentrated manner and then disperse for wiring increase the number of structures and the design difficulty.

[0076] The above embodiments are only exemplary embodiments of the present invention and are not used to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present invention, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present invention.
