Description

Technical Field

[0001] This utility model provides a composite material support structure, and particularly relates to a composite material support structure for a vertical air sail. Background Technology

[0002] As a novel energy-saving device for ships, the vertical airsail's support structure plays a crucial role. Existing vertical airsail support structures mostly employ traditional metal frames or simple composite material frames, with basic structures typically consisting of simple columnar or frame supports. However, these existing support structures have several shortcomings in practical applications. On the one hand, their overall strength is limited, making them prone to deformation under strong winds, water currents, and their own weight. This causes the vertical airsail to lose its stable posture, affecting its energy-saving effect and service life. On the other hand, existing support structures have poor resistance to deformation, exhibiting significant stress concentration under load, leading to localized damage and reducing the overall reliability and durability of the device, making it difficult to meet the requirements for long-term stable operation of ships in complex marine environments. Furthermore, some metal support structures suffer from excessive weight and poor corrosion resistance, increasing the burden on the ship and affecting its overall performance. Utility Model Content

[0003] In order to solve the above problems, this application provides a composite material support structure for a vertical air sail, which solves the problems of insufficient strength, easy deformation and poor durability of existing support structures.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a composite material support structure for a vertical air sail, comprising a slender elliptical cylindrical shell, the shell being made of composite material with a smooth surface and a streamlined shape; on the shell, a plurality of circular holes are sequentially provided at the middle position along its length direction, each of the circular holes having a support frame inside, the four ends of the support frame being fixedly connected to the inner wall of the circular hole respectively; on the side of the shell near the top, a plurality of elongated holes are provided, the inner side of the elongated holes having arc-shaped reinforcing ribs placed inside the shell.

[0005] Preferably, the outer shell has multiple intersecting and connected rectangular frames inside, each rectangular frame being assembled from composite material rods, and the rectangular frames are fixedly connected to the outer shell by several evenly distributed connectors.

[0006] Preferably, the rectangular frame and the support frame are distributed in a three-dimensional cross shape, forming a stable support structure for the internal space of the shell.

[0007] Preferably, the rectangular frame has several evenly distributed stabilizing plates on both sides that penetrate it. The stabilizing plates are distributed in the intersection area of ​​the rectangular frame. The stabilizing plates and the rectangular frame together form a multi-layer three-dimensional support system, which further enhances the stability and load-bearing capacity of the structure.

[0008] Preferably, the rectangular frame members are further connected with several symmetrically arranged diagonal braces, and the outside of the stabilizing plate is provided with several reinforcing rods that clamp itself. One end of each diagonal brace is connected to a member, and the other end is connected to an adjacent cylindrical reinforcing rod. The diagonal braces disperse stress and improve the structure's resistance to deformation.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] This device is composed of multiple components made of high-strength composite materials, including an elliptical cylindrical shell, a barrel-shaped support structure, cross-shaped connectors, round hole reinforcing ribs, cylindrical supports, a rectangular frame, connectors, a stabilizing plate, diagonal braces, and reinforcing rods. These components work together through a scientific and reasonable connection method to form a multi-layered, three-dimensional, cross-support system.

[0020] like Figure 1 and Figure 2 As shown, this utility model relates to a composite material support structure for a vertical air sail. The overall structure is a slender elliptical cylindrical shell 1, made of composite material with a smooth, streamlined surface. Several circular holes 2 are sequentially arranged at the midpoint of the elliptical cylindrical shell 1 along its length. Each circular hole 2 contains a support frame 3, with its four ends fixedly connected to the inner wall of the hole. Simultaneously, several elongated holes 4 are provided on the side of the shell 1 near the top. Arc-shaped reinforcing ribs 5 are located inside the holes, providing basic reinforcement support for the shell 1 in the area surrounding the holes.

[0021] In this embodiment, the interior of the outer shell 1 contains multiple intersecting and interconnected rectangular frames 6. Each rectangular frame 6 is constructed from composite material rods, which are fixedly connected by connectors 7 to form a unified three-dimensional intersecting frame system. The rectangular frames 6 are fixedly connected to the outer shell 1 by several evenly distributed connectors 7, ensuring a tight fit and coordinated operation between the frames and the outer shell. Simultaneously, the rectangular frames 6 and the support frame 3 are distributed in a three-dimensional intersecting pattern, further enhancing the stable support structure for the interior space of the outer shell 1, effectively resisting external forces and preventing overall deformation of the outer shell 1 during use. Several evenly distributed and penetrating stabilizing plates 8 are provided on both sides of the rectangular frames 6. The stabilizing plates 8 are distributed in the intersection areas of the rectangular frames 6, forming a multi-layered three-dimensional support system together with the rectangular frames 6, further enhancing the stability and load-bearing capacity of the structure. Furthermore, several symmetrically arranged diagonal tie rods 9 are connected to the rods of the rectangular frames 6, and several reinforcing rods 10 are provided on the outside of the stabilizing plates 8 to hold them in place. One end of the diagonal tie rod 9 is connected to the rod, and the other end is connected to the adjacent cylindrical reinforcing rod 10. By dispersing stress, it improves the structure's resistance to deformation, thereby achieving a superior support effect. This device, through its multi-layered, three-dimensional, cross-support system and stress dispersion design, effectively improves the support strength, stability, and durability of the vertical airsail. It solves the problems of insufficient strength, susceptibility to deformation under stress, and poor durability of existing support structures, ensuring the vertical airsail can operate stably for extended periods in complex environments, meeting the needs of fields such as marine engineering. The components work synergistically: the outer shell 1 provides basic support and a streamlined shape; the circular opening 2 and its internal support frame 3 strengthen the local structure; the arc-shaped reinforcing ribs 5 within the elongated opening 4 further enhance local strength; the rectangular frame 6 and the stabilizing plate 8 form a robust internal support structure; and the diagonal tie rod 9 and reinforcing rod 10 disperse stress, collectively improving the overall support effect and resistance to deformation of the device.

[0022] like Figure 2 and Figure 3 As shown, the elliptical cylindrical shell 1 contains multiple intersecting and connected rectangular frames 6, which are assembled from composite material rods and fixedly connected to the shell 1 via evenly distributed connectors 7. The rectangular frames 6 and the support frame 3 are distributed in a three-dimensional intersecting pattern, forming a stable internal support structure. Stabilizing plates 8 penetrate the rectangular frames 6 on both sides, distributed in the intersecting areas and forming a multi-layered three-dimensional support system with the frames, enhancing structural stability and load-bearing capacity. Furthermore, symmetrically arranged diagonal tie rods 9 are connected to the rods of the rectangular frames 6, and several reinforcing rods 10 clamp the outside of the stabilizing plates 8. One end of the diagonal tie rod 9 is connected to the rod, and the other end is connected to an adjacent cylindrical reinforcing rod 10, effectively dispersing stress, improving resistance to deformation, and fully ensuring the stability and reliability of the vertical air sail in practical applications.

[0023] In this embodiment, in actual use, this device will also be installed in conjunction with the existing vertical air sail's canvas or membrane (not shown). The canvas or membrane is fixed to this support structure using existing connection techniques and mounting brackets (not shown) to form a complete vertical air sail. Furthermore, when this device is installed on a ship or other carrier, it will be secured using existing mounting brackets and fasteners, via the bottom of the outer shell 1 or specific connection points. Regarding material selection, composite material components such as the outer shell 1, support frame 3, and rectangular frame 6 in this device can be made of carbon fiber composites, glass fiber composites, or aramid fiber composites. These materials possess high strength, lightweight, corrosion resistance, and good fatigue resistance, effectively improving the performance of the entire support structure. For example, the high strength and lightweight characteristics of carbon fiber composites allow this device to significantly reduce its own weight while ensuring support strength, reducing the burden on ships and other carriers; while glass fiber composites have advantages such as relatively low cost, ease of molding, and good insulation properties, and can be selected according to actual application requirements and cost budget. By using it in conjunction with existing technologies such as canvas, membrane, mounting brackets and fasteners, and by adopting high-performance composite materials, this device can better leverage its support advantages and achieve efficient and stable operation of the vertical air sail in various application scenarios.
