Description

Technical Field

[0001] The utility model relates to the technical field of ships, in particular to a sail base and an oil tanker. Background Art

[0002] When sailing at sea, ships can use sailing equipment to directly convert wind energy into auxiliary propulsion. Combining aerodynamic technology and ship design, these sails can autonomously adjust to wind changes, maximizing wind energy utilization and reducing fuel consumption in the main propulsion diesel engines, ultimately achieving energy conservation and emission reductions. Generally speaking, sails are primarily secured to the hull via sail bases. These bases are located on the upper deck. During navigation, under the influence of wind loads, the weight of the equipment, and the additional acceleration of the hull's motion, these bases can easily deform significantly, and in severe cases, can directly damage the sails and hull structure.

[0003] The prior art (201811588506.3) discloses a sail base reinforcement structure, comprising a cylindrical base located above the deck, a bracket provided at a right angle between the base and the deck, and a plurality of parallel longitudinal girders located below the deck for supporting the deck. A plurality of curved reinforcement plates are connected between the longitudinal girders, and the curved reinforcement plates form a cylindrical reinforcement body vertically aligned with the base; a plurality of flat reinforcement plates are also provided between the longitudinal girders and between the longitudinal girders and the cylindrical reinforcement body.

[0004] While existing sail base reinforcements effectively support the mast, they only work with fixed masts and cannot be retracted or extended, resulting in low propulsion efficiency. This makes them suitable only for small vessels. The large, hydraulically controlled sails used on today's medium- to large-sized oil tankers and cargo ships are unsuitable for these sail bases. Furthermore, existing sail base reinforcements require a specific design based on the deck structure, which is complex and may even require extensive changes to the deck structure, resulting in high costs and impacting cabin capacity. Utility Model Content

[0005] The purpose of the utility model is to provide a sail base and an oil tanker, so as to solve the technical problems existing in the prior art that the sail base has poor adaptability, complicated design and high cost.

[0037] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0038] Example 1

[0039] The embodiment of the utility model provides a sail base, which can achieve a supporting effect for sail equipment.

[0040] See also Figures 1 to 7The sail base provided by the present invention includes a base body 1, a fixing structure 2, and a reinforcement structure. The base body 1 is disposed on a deck 100 and comprises a multi-section base formed integrally. The multi-section base together encloses a receiving space 13 with an opening at the top. The sailing equipment is placed in the receiving space 13. The side walls of the receiving space 13 form at least one escape opening 14 to facilitate the entry and exit of the sailing equipment. The fixing structure 2 is disposed on the base body 1 and is detachably connected to the sailing equipment for securing the sailing equipment. The reinforcement structure is disposed on the base body 1 and is connected to the deck 100.

[0041] The present invention proposes a sail base. The base body 1 is formed of a multi-section, integrally formed base body, forming a top-opening accommodation space 13. This provides a stable and organized placement space for the sailing equipment, better adapting to the shape and size of the sailing equipment. Sidewalls of the accommodation space 13 are provided with a clearance opening 14 for accommodating components such as hydraulic rods, enabling the sailing equipment to be placed upright or horizontally. This facilitates the normal operation of the sailing equipment within the accommodation space 13 and prevents the base body's outer wall from interfering with the deployment and retrieval of the sailing equipment. This makes the disassembly and maintenance of the sailing equipment more convenient and efficient, eliminating the need for complex disassembly of the sail base. This reduces the number of steps and time required, improves work efficiency, and ensures the normal operation and deployment of the sailing equipment while meeting strength requirements. The fixing structure 2 is detachably connected to the sailing equipment. This not only ensures that the sailing equipment is firmly fixed during navigation, enhancing navigation safety and stability, but also facilitates the replacement or repair of the sailing equipment when needed, improving the equipment's maintainability and service life. The reinforcement structure is arranged on the base body 1 and connected to the deck 100, which enhances the connection strength and stability between the base body 1 and the deck 100, can effectively disperse and bear various loads such as wind load and equipment weight, avoids large deformation of the base, and reduces damage to the hull structure; at the same time, the connection and reinforcement of the base body 1 and the deck 100 are all above the upper deck 100, and there is no need for large-scale reinforcement and modification under the deck 100, and the structure of the deck 100 will not be changed, which reduces the complexity and cost of the design and improves the space utilization of the sail base.

[0042] The specific structure of the sail base is described below.

[0043] See also Figure 1 and Figure 2The base body 1 includes three sections of bases, namely a main base 11 extending along a first straight line direction and two side bases 12 extending perpendicular to the first straight line direction. The main base 11 and the two side bases 12 are arranged in a U-shape and together enclose a accommodating space 13. The side walls of the accommodating space 13 form a avoidance opening 14, and the main base 11 faces the avoidance opening 14. The design of the base body 1 with a U-shaped structure conforms to the principles of mechanics and can more evenly disperse stress when subjected to external forces such as wind loads, thereby improving the overall stability and load-bearing capacity of the base body 1 and reducing the risk of deformation. The design of a avoidance opening 14 and the main base 11 facing each other simplifies the path for the sailing equipment to enter and exit, making operation more convenient, reducing complex operating procedures, and improving the efficiency of installation and maintenance.

[0044] Here, the direction of the base body 1 facing the avoidance opening 14 is defined as the front end, and the direction of the base body 1 away from the avoidance opening 14 is defined as the rear end. For the convenience of description in conjunction with the drawings, the directions below are described in accordance with the directions shown in the drawings, but are not limited thereto.

[0045] In order to ensure that the base body 1 has sufficient supporting strength, one of the side bases 12 is arranged on the inner shell of the hull, and the other side base 12 is arranged on the deck 100. It can be appropriately adjusted according to actual working conditions to facilitate the installation of the reinforcement structure and ensure the longitudinal continuity of the hull structure; the distance between the front and rear ends of the base body 1 is adaptively adjusted according to the size of the sail equipment. There is no limitation here. It is only necessary to ensure that the sail equipment has sufficient installation space.

[0046] Considering that the base body 1 is provided with a fixing structure 2 for fixing the sailing equipment, in order to improve the support for the sailing equipment, a longitudinal strong frame structure 15 is arranged below the corresponding position of the fixing structure 2. Figure 3 The inner wall of the side base 12 is provided with a longitudinal strong frame structure 15, with part of the sail equipment abutting against the top of the longitudinal strong frame structure 15. The longitudinal strong frame structure 15 enhances the structural strength and rigidity of the side base 12, better able to withstand the lateral pressure from the sail equipment and the lateral force caused by wind loads, further reducing the risk of deformation of the side base 12 and ensuring the stability of the sail base. In addition, the longitudinal strong frame structure 15 provides a stable support point for the sail equipment, making the installation of the sail equipment more stable and reliable, reducing the shaking and displacement of the equipment during operation, and improving the operating precision and safety of the sail equipment.

[0047] It is worth noting that longitudinal bones are provided on the base body 1. In order to prevent the longitudinal bones from interfering with the installation process of the longitudinal strong frame structure 15, the longitudinal bones are deleted from the base body 1 and replaced with strong T-materials, which not only ensures the strength of the structure but also does not interfere with the installation process of the longitudinal strong frame structure 15.

[0048] Regarding the fixing structure 2, in this embodiment, the fixing structure 2 is hingedly connected to the sailing equipment, thereby improving the flexibility of the sailing equipment after being fixed. In other embodiments, the fixing structure 2 and the sailing equipment can also be connected by bolts, pins, or snaps, etc., without limitation here, as long as the sailing equipment is effectively fixed.

[0049] See also Figure 4 Because sailing equipment is installed on top of the longitudinal strong frame structure 15, a cutout 151 is provided to prevent interference. Cutout 151 provides access to the sailing equipment, preventing interference and compression between these components and the longitudinal strong frame structure 15, ensuring a smooth and secure connection. It also optimizes spatial layout, making the installation of the sailing equipment and its associated components more compact and efficient, improving space utilization.

[0050] In other embodiments, if the sailing equipment does not interfere with the longitudinal strong frame structure 15 , the ferry opening 151 may not be provided to ensure the strength of the longitudinal strong frame structure 15 , thereby ensuring the integrity of the longitudinal strong frame structure 15 .

[0051] Furthermore, slots 152 are formed through the sidewalls of the longitudinal strong frame structure 15 along its thickness. This allows the sail base to cross over the strong crossbeam, leaving ample space for construction and maintenance. Furthermore, slots 152 facilitate access to the interior of the longitudinal strong frame structure 15 for equipment disassembly, maintenance, and repair.

[0052] Specifically, two through-slots 152 are provided, located on either side of the diagonal of the longitudinal strong frame structure 15. An oblique support 153 is positioned between the two through-slots 152 to ensure structural continuity. Furthermore, it is worth noting that each corner of the through-slots 152 is rounded to reduce stress concentration. The radius of the rounded corners can be 350 mm, 500 mm, etc., and is not limited here.

[0053] See also Figure 5 and Figure 6, the outer wall of the base body 1 is provided with a plurality of reinforcing structures 16, which extend in the horizontal direction, and the plurality of reinforcing structures 16 are arranged at intervals along the height direction of the base body 1. The provision of the reinforcing structure 16 enhances the overall strength and rigidity of the base body 1, and can more effectively resist various external forces generated by wind loads, equipment deadweight, and additional acceleration of the hull movement, thereby reducing the deformation and damage risks of the base body 1. The reinforcing structure 16 extending in the horizontal direction can evenly disperse external forces and avoid stress concentration in a specific area. The plurality of reinforcing structures 16 are arranged at intervals along the height direction, so that the reinforcing structure 16 is evenly loaded, and no matter which part of the base body 1 is acted upon by external forces, it can be effectively supported and resisted, further ensuring the normal operation of the sail base under complex working conditions.

[0054] In this embodiment, the reinforcement structure 16 is made of flat iron, which is a prior art device in this field. Its working principle and specific structure are not described in detail here.

[0055] See also Figure 7 To further enhance the strength and rigidity of the base body 1, vertical stiffeners 17 are installed on the outer wall of the base body 1, extending along its height. These stiffeners 17 enhance the base body 1's vertical load-bearing capacity and bending resistance, effectively counteracting the gravity of the sailing equipment and the base itself, as well as the vertical inertial forces generated by the hull's motion, and reducing deformation and bending of the base body 1 along its height. The vertical stiffeners 17, extending along its height, work in conjunction with the horizontal reinforcement structures 16 to form a crisscross reinforcement system, further enhancing the overall strength and stability of the base body 1 and enabling it to better handle complex loads from all directions.

[0056] It is understandable that the vertical stiffener 17 is a common mechanical component in this field, and its working principle and specific structure are not described in detail here.

[0057] The front end of the base body 1 is partially open due to the cutout 14, resulting in a loss of rigidity. However, structural reinforcement with flat iron and vertical stiffeners 17 ensures the rigidity and strength of the base body 1 while unrestricting the movement and installation of the sailing equipment within the accommodating space 13. Furthermore, to ensure rigidity, the base body 1 is constructed with a thicker plate. Furthermore, the top surface of the base body 1 is further thickened within a certain range where the sailing equipment is mounted, ensuring localized rigidity.

[0058] More specifically, a support plate is provided between the base body 1 and the deck 100. The support plate is used to place sailing equipment and other related devices. At the same time, it can effectively ensure the longitudinal strength of the base body 1 and provide lateral support for the longitudinal strong frame structure 15 of the inner wall of the two side bases 12.

[0059] Regarding the reinforcement structure, in this embodiment, the bracket 3 is a bracket plate 3, one end of which is connected to the base body 1 and the other end to the deck 100. A chamfer is formed between the ends of the bracket plate 3. The bracket plate 3 effectively transfers the load borne by the base body 1 to the deck 100, enhancing the strength and stability of the connection between the base body 1 and the deck 100, thereby reducing deformation and displacement of the base and ensuring the normal operation of the windsurfing equipment. The chamfer between the ends of the bracket plate 3 reduces stress concentration, avoids localized high-stress areas at the connection, and extends the service life of the bracket plate 3 and the entire connection structure.

[0060] Example 2

[0061] The embodiment of the present invention also provides a ship, including a hull, a sail equipment and a sail base, wherein the hull is provided with a sail base, and the sail equipment is connected to the sail base. By adopting the above-mentioned sail base, the oil tanker provides a stable, reliable and adaptable support structure for the sail equipment on the hull. It can be applied to large hydraulically controllable sails equipped on medium and large oil cargo ships, effectively preventing the sail base and sail equipment from being deformed or damaged due to factors such as wind load, equipment deadweight and additional acceleration of the hull movement in complex marine environments, ensuring the normal operation of the sail equipment during the navigation of the oil tanker, thereby giving full play to the auxiliary propulsion role of the sail equipment, improving the energy utilization efficiency of the oil tanker, reducing fuel consumption, and achieving energy conservation and emission reduction.

[0062] The above embodiments merely illustrate the basic principles and features of the present invention. The present invention is not limited to the above embodiments.
