Description

Technical Field

[0001] This utility model relates to the field of ship hull rib reinforcement technology, specifically a reinforcing rib for the hull structure of an electric bulk carrier. Background Technology

[0002] Electric bulk carriers, due to the large number of battery packs and electrical equipment they carry, have different hull load requirements than traditional bulk carriers. To ensure the strength and stability of the hull structure, optimized hull design is necessary, especially the design of the hull reinforcing ribs. Because there are a large number of electrical devices that need to be connected by cables, a lot of cables need to be laid and they pass through a lot of areas. Traditional cable laying methods can damage the ribs and reduce their structural strength. Therefore, this application provides a reinforcing rib for the hull structure of an electric bulk carrier. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a reinforcing rib plate for the hull structure of an electric bulk carrier, which solves the problem that the traditional through-lay method would damage the rib plate and reduce its structural strength.

[0004] The present invention relates to a reinforcing rib plate for the hull structure of an electric bulk carrier, comprising a rib plate for support and a flange disposed on the outer side of the rib plate. The rib includes a plate body, and one or more channels are provided on the inner side of the plate body for passing cables. The flange includes side plates, and there are one or more side plates distributed on the outer side of the plate.

[0005] As a further improvement of this utility model, one or more cavities are provided on the top of the plate, and one or more reinforcing ribs are provided on the inner side of the cavity.

[0006] As a further improvement of this utility model, the reinforcing rib includes horizontal ribs and vertical ribs, the horizontal ribs and vertical ribs are staggered at a preset angle, and the two ends of the horizontal ribs and vertical ribs are respectively connected to the inner sidewall of the cavity.

[0007] As a further improvement of this utility model, the horizontal and vertical ribs are arranged at equal intervals, and a reinforcement area is formed between the horizontal and vertical ribs. The intersection points of the horizontal and vertical ribs are integrated.

[0008] As a further improvement of this utility model, the inner side of the cavity is located at the intersection of the horizontal and vertical ribs and is adapted to the channel for cable arrangement.

[0009] As a further improvement of this utility model, the inner side of the side plate is hollow and connected to the channel.

[0010] As a further improvement of this utility model, a bottom reinforcing plate is provided at one end of the two side plates that are close to each other, and the two ends of the bottom reinforcing plate are connected to the side plates.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model significantly improves the overall structural strength of the ribs and hull by setting channels inside the ribs, setting cavities inside the side plates, installing reinforcing ribs and bottom reinforcing plates. The grid structure of the reinforcing ribs and the setting of the bottom reinforcing plates optimize the stress distribution, reduce the risk of deformation and damage to the hull when subjected to loads and external impacts, and ensure the stability of the hull. The interconnectivity design of the channels and cavities ensures the smooth laying of cables within the hull, avoiding the damage to the rib structure caused by traditional cable laying methods. The compact arrangement of cables within the channels and the support design of the bottom reinforcement plate reduce cable crossing, friction, and wear, improving cable safety and service life, thereby enhancing the overall reliability of the power system. The integrated design and pre-designed channel structure simplify the hull manufacturing and cable laying process, reduce on-site construction workload, and improve manufacturing and installation efficiency. The hollow design and lightweight structure of the side plates reduce the total weight of the hull, reduce material costs and energy consumption, and improve the economy and energy efficiency of the electric bulk carrier. By optimizing the structural design of the ribs and side plates, the hull can better disperse stress when facing external impacts such as wind, waves and collisions, reducing the risk of local structural damage.

[0016] Please see Figure 1-5 Electric bulk carriers, due to the large number of battery packs and electrical equipment they carry, have different hull load requirements than traditional bulk carriers. To ensure the strength and stability of the hull structure, the hull structure needs to be optimized, especially the design of the hull reinforcing rib 1; Since there are a large number of electrical devices, and these devices need to be connected by cables, a lot of cables need to be laid and they need to pass through a lot of areas. The traditional method of laying cables through the area will damage the rib plate 1 and reduce the structural strength of the rib plate 1. Based on this, this application provides a reinforcing rib plate 1 for the hull structure of an electric bulk carrier, including a rib plate 1 for support and a flange 2 provided on the outside of the rib plate 1. Rib 1 includes a plate body 11, and one or more channels 13 are provided on the inner side of the plate body 11 for passing cables. The flange 2 includes side plates 21, which are one or more and distributed on the outer side of the plate body 11.

[0017] The rib plate 1 consists of one or more plates 11, which are hollow structures with one or more channels 13 inside. These channels 13 are specifically designed for the passage of cables, avoiding the damage to the structural strength of the rib plate 1 caused by traditional cable laying methods.

[0018] The inner surface of the plate 11 is specially treated, such as by coating or polishing, to ensure smoothness, so that the cable can pass smoothly in the channel 13, while reducing friction and wear and extending the service life of the cable.

[0019] The geometry and dimensions of channel 13 are optimized according to the specifications and quantity of the cables to ensure that the cables can be arranged compactly within channel 13 without affecting the overall structural strength of the hull.

[0020] Flange 2 is provided on the outer side of rib 1 to enhance the load-bearing capacity and stability of rib 1.

[0021] The flange 2 includes one or more side plates 21, the number and distribution of which are designed according to the specific structure and load-bearing requirements of the hull.

[0022] The side plate 21 is connected to the outer side of the plate 11 by bolts or welding to ensure that the flange 2 and the rib plate 1 form a whole, thereby enhancing the overall strength of the rib plate 1.

[0023] The side plate 21 is made of high-strength steel or composite materials, such as aluminum alloy or carbon fiber, to ensure that it will not deform or be damaged when subjected to the weight of the hull and the impact of the external environment.

[0024] The cable is laid through the channel 13 inside the plate 11, avoiding the situation where the cable passes directly through the rib plate 1 in the traditional way, thereby reducing damage to the rib plate 1.

[0025] The arrangement of cables within channel 13 has been optimized to avoid mutual interference between cables, while reducing cable overlap and crossing, thus lowering electromagnetic interference between cables.

[0026] Sealing devices are installed at the entrance and exit of channel 13 to prevent external substances such as water and dust from entering channel 13 and affecting the normal operation of the cable and the safety of the ship.

[0027] The design of rib 1 and flange 2 not only takes into account the cable passage requirements, but also optimizes the overall design with other structural components of the hull (such as decks, bulkheads, etc.) to ensure that the hull maintains good stability and strength when carrying a large number of battery packs and electrical equipment.

[0028] By locally reinforcing the ribs 1 and rationally distributing the flanges 2, the hull can better disperse stress and avoid local structural damage when subjected to external impacts such as wind and waves.

[0029] By setting the channel 13 inside the rib plate 1, the damage to the rib plate 1 caused by the traditional cable laying method is avoided, ensuring that the structural strength of the rib plate 1 is not affected, thereby improving the overall strength and stability of the hull.

[0030] Flange 2 further enhances the load-bearing capacity of rib 1, enabling the hull to maintain good structural stability even when carrying a large number of battery packs and electrical equipment.

[0031] The cable is laid through the channel 13 inside the rib plate 1, which avoids the situation where the cable passes directly through the rib plate 1 in the traditional way, simplifies the cable laying process and reduces the construction difficulty.

[0032] Channel 13 makes the cable arrangement more compact and orderly, reduces mutual interference and electromagnetic interference between cables, and improves the working efficiency and reliability of power equipment.

[0033] The cable laying method in channel 13 reduces cable friction and wear, extending the cable's service life.

[0034] The sealing devices at the entrance and exit of channel 13 effectively prevent external substances (such as water, dust, etc.) from entering, further extending the service life of the cable.

[0035] By optimizing rib 1 and flange 2, the hull can better disperse stress when facing external impacts (such as wind, waves, collisions, etc.), reducing the risk of local structural damage and improving the safety and reliability of the hull.

[0036] The sealed design of cable channel 13 ensures the safety of the hull in harsh environments and reduces safety hazards caused by cable failures.

[0037] The simplified cable laying method reduces construction time and labor costs, lowers the overall cost of hull construction, and the compact arrangement of cables and the design of channel 13 reduce the probability of cable damage, thus reducing subsequent maintenance and replacement costs.

[0038] The top of the plate 11 has one or more cavities 12 facing downwards, and one or more reinforcing ribs 14 are provided on the inner side of the cavity 12.

[0039] The reinforcing rib 14 includes transverse ribs and longitudinal ribs. The transverse ribs and longitudinal ribs are staggered at a preset angle, and the two ends of the transverse ribs and longitudinal ribs are respectively connected to the inner wall of the cavity 12.

[0040] The horizontal and vertical bars are spaced at equal intervals, and a reinforced area is formed between them. The intersections of the horizontal and vertical bars are integrated.

[0041] The inner side of cavity 12 is located at the intersection of horizontal and vertical ribs and is adapted to channel 13 for cable arrangement.

[0042] One or more cavities 12 are formed downward on the top of the plate 11 of the rib plate 1. These cavities 12 are used to install reinforcing ribs 14 to enhance the rigidity and strength of the plate 11. The shape and size of the cavity 12 are designed according to the size of the plate 11 and the required degree of reinforcement, and can be rectangular, trapezoidal or other suitable shapes.

[0043] One or more reinforcing ribs 14 are provided on the inner side of each cavity 12. The reinforcing ribs 14 are composed of horizontal ribs and vertical ribs, which are staggered at a preset angle to form a grid structure. The angle between the horizontal ribs and the vertical ribs can be determined according to the stress condition of the plate 11. Common angles include 90-degree right angles or other angles to achieve the best reinforcement effect.

[0044] The horizontal and vertical ribs are set at equal intervals to ensure that the stress is evenly distributed throughout the cavity 12. The intersections of the horizontal and vertical ribs are integrated, that is, they are welded or integrally formed at the intersections to improve the stability of the structure.

[0045] Inside the cavity 12, the intersection of the horizontal and vertical ribs is adapted to the cable channel 13. In other words, the position of the cable channel 13 matches the layout of the reinforcing rib 14, which ensures the smooth passage of the cable without affecting the reinforcing effect of the reinforcing rib 14 on the plate 11.

[0046] The cables are neatly arranged in channel 13, and the design of channel 13 fully considers the bending radius and heat dissipation requirements of the cables, ensuring the safe and efficient operation of the cables.

[0047] By setting a cavity 12 at the top of the plate 11 and installing reinforcing ribs 14, the rigidity and strength of the plate 11 are significantly enhanced, enabling the rib plate 1 to better withstand the load of the hull and external impacts.

[0048] The mesh structure of the reinforcing rib 14 effectively disperses stress and reduces the risk of deformation or damage to the plate 11.

[0049] The cable channel 13 and the reinforcing rib 14 are matched in layout, making the cable laying more reasonable and efficient, reducing the crossing and interference between cables, and the cables are neatly arranged in the channel 13, which is convenient for maintenance and management, and also improves the efficiency and safety of power transmission.

[0050] The addition of stiffener 14 not only enhances the local strength of rib plate 1, but also improves the stability of the entire hull structure, making the hull more stable and safer during navigation.

[0051] The inner side of the side plate 21 is hollow and connected to the channel 13.

[0052] A bottom reinforcing plate 22 is provided at one end of the two side plates 21 that are close to each other, and the two ends of the bottom reinforcing plate 22 are connected to the side plates 21.

[0053] The inner side of the side plate 21 is hollow. This design not only reduces the weight of the side plate 21, but also enhances its rigidity and stability.

[0054] The hollow portion of the side plate 21 is connected to the cable channel 13 inside the plate body 11, forming a continuous channel 13 system, which facilitates cable laying and management. This design ensures the smooth passage of cables while reducing cable bending and wear.

[0055] A bottom reinforcing plate 22 is provided at one end of the two side plates 21 that are close to each other. The shape and size of the bottom reinforcing plate 22 are optimized according to the design requirements of the side plates 21, and are usually rectangular or trapezoidal to accommodate the cable laying requirements.

[0056] The two ends of the bottom reinforcing plate 22 are connected to the hollow part of the side plate 21, forming an integral reinforcing structure. This design not only enhances the local strength of the side plate 21, but also provides additional support and protection for the cable.

[0057] The bottom reinforcing plate 22 is fixed to the side plate 21 by welding or bolting to ensure the strength and stability of the connection.

[0058] The connection between the reinforcing plate and the side plate 21 is specially treated to reduce stress concentration and improve the overall durability of the structure.

[0059] The hollow portion of the side plate 21 is connected to the cable channel 13 inside the plate 11, forming a continuous and unobstructed channel 13 system. This design ensures the smooth laying of cables within the hull and reduces cable crossings and interference.

[0060] The design of the bottom reinforcement plate 22 further optimizes the cable arrangement, ensuring that the cable is not squeezed or rubbed when passing through the bottom reinforcement plate 22, thus extending the service life of the cable.

[0061] The hollow design of the side plate 21 and the setting of the bottom reinforcing plate 22 significantly enhance the local strength of the side plate 21, enabling the side plate 21 to better withstand the load of the hull and external impacts.

[0062] The connection between the bottom reinforcing plate 22 and the side plate 21 optimizes stress distribution and reduces the risk of deformation and damage to the side plate 21.

[0063] The hollow portion of the side plate 21 is connected to the cable channel 13 inside the plate 11, forming a continuous and unobstructed channel 13 system. This design ensures the smooth laying of cables within the hull and reduces cable crossings and interference.

[0064] The design of the bottom reinforcement plate 22 further optimizes the cable arrangement, ensuring that the cable is not squeezed or rubbed when passing through the bottom reinforcement plate 22, thus extending the service life of the cable.

[0065] The hollow design of the side plate 21 and the installation of the bottom reinforcing plate 22 not only enhance the local strength, but also improve the stability of the entire hull structure, making the hull more stable and safer during navigation.

[0066] The design of the side panel 21 and the bottom reinforcement plate 22 can adopt integrated manufacturing technology, which simplifies the production process and reduces manufacturing costs. During installation, the pre-set cable channel 13 reduces the amount of on-site wiring and improves installation efficiency.
