Description

Technical Field

[0001] This utility model relates to the field of navigation aid equipment technology, and in particular to a new type of tethering ring installation structure for navigation aid buoys. Background Technology

[0002] With the rapid development of my country's shipping industry, the number and tonnage of ships have continued to grow, and the number of maritime bridges, port terminals, and various water engineering projects has increased, placing higher demands on maritime traffic safety. As an important navigational aid to ensure the safety of ship navigation, the stable and reliable operation of navigation marks is crucial. Among them, the buoy is the core component of a light buoy, used to provide buoyancy to support the navigation mark equipment floating on the water surface.

[0003] Aside from collisions, most damage to buoys involves broken welded structures of the mooring links at the bottom of the buoy. As a crucial component of navigational aids, the buoy is the core element ensuring its buoyancy. Damage to the mooring link welds allows significant water ingress, causing the buoy to tilt or sink, severely reducing its effectiveness and potentially turning it into a navigational obstacle. Furthermore, buoy buoys are inherently valuable, and repairs after damage are difficult, requiring large navigational aid lifting vessels for replacement, consuming substantial manpower and resources.

[0004] Current navigational buoys typically consist of simple chain links welded to the bottom bulkhead for positioning. However, in actual use, buoys are constantly exposed to complex and variable marine environments, subjected to various external forces such as wind, waves, tides, ship collisions, and anchor chain tension. Especially under strong wind and wave conditions, when the anchor chain exerts enormous tensile, torsional, and impact stress on the chain links, the chain links simply welded to the bottom bulkhead cannot withstand the tensile stress of the bottom anchor chain, leading to breakage and cracking. After damage, a large amount of water enters, which can easily cause the navigational buoy to tilt or sink.

[0005] Therefore, how to enhance the strength and reliability of the bottom mooring chain connection structure of the buoy buoy, and improve its tensile, torsional and fatigue resistance, has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0006] This utility model proposes a novel tethering ring installation structure for navigation buoys, which greatly enhances the strength and stability of the welded joints, giving the tethering rings stronger tensile and torsional resistance, and solving the aforementioned problems existing in the use of existing technologies.

[0007] The technical solution of this utility model is implemented as follows: A novel tethering ring installation structure for a navigation buoy includes a buoy body and tethering rings. The buoy body includes an annular outer wall, a top bulkhead, a bottom bulkhead, and steel bulkheads. The top and bottom bulkheads are welded and fixed to the upper and lower sides of the outer wall of the buoy, respectively. Several steel bulkheads are provided and welded to the inner wall of the buoy. The upper and lower ends of the steel bulkheads are welded to the top and bottom bulkheads, respectively. The steel bulkheads divide the internal space enclosed by the outer wall of the buoy, the top bulkhead, and the bottom bulkhead into several compartments. Several tethering rings are provided on the bottom bulkhead and correspondingly welded to the bottom of the bottom bulkhead and the bottom of the steel bulkhead.

[0008] Preferably, the steel partition is provided with four sections that are welded together in a cross shape.

[0009] Preferably, four chain links are provided on the bottom bulkhead, and are respectively welded to the bottom of the four steel bulkheads.

[0010] Preferably, the tethering link is U-shaped, and the end of the tethering link passes through the bottom bulkhead and is welded to the bottom of the steel bulkhead.

[0011] Preferably, the chain link is provided with an inner welding pressure plate and an outer welding pressure plate, which are fixed on the chain link and welded to the inner and outer sides of the bottom bulkhead respectively.

[0012] Preferably, a structural reinforcing plate is welded and fixed between the two ends of the chain link.

[0013] Preferably, the top bulkhead is provided with four lifting rings, the structure of which is the same as that of the chain link, and the four lifting rings are respectively welded and fixed to the top of four steel bulkheads.

[0014] In summary, the beneficial effects of this utility model are as follows: 1. This utility model welds the mooring chain ring to the connection between the steel bulkhead inside the pontoon and the bottom bulkhead. Because the steel bulkhead itself has high structural strength and penetrates the interior of the pontoon, using it as the welding base for the mooring chain ring significantly enhances the load-bearing capacity of the connection. Under stress, the steel bulkhead acts as a "reinforcing rib," effectively dispersing the tensile force, torsional load, and impact stress transmitted by the anchor chain, preventing stress concentration that could lead to weld cracking.

[0015] 2. By setting up four steel bulkheads arranged in a cross shape, four symmetrical sealed compartments are formed inside the pontoon. This not only improves the rigidity and deformation resistance of the overall structure but also provides four evenly distributed high-strength welded support points for the mooring links. The cross-shaped layout has good mechanical symmetry, enabling balanced load transfer when subjected to anchor chain tension or torsional loads from any direction. This further reduces local stress concentration, enhances the structure's fatigue resistance, and helps extend the pontoon's service life. Furthermore, a mooring link is placed at the bottom of each of the four steel bulkheads, forming a multi-point anchoring structure that allows for redundant connections or distributed stress distribution within the anchor chain system. Even if one mooring link or a local weld is damaged, the remaining mooring links can still maintain basic connection function, preventing sudden overall failure. Attached Figure Description

[0019] The following will refer to the appendix in the embodiments of this utility model. Figure 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Example: like Figures 1 to 5 As shown, this utility model discloses a novel chain link installation structure for a navigation buoy pontoon, including a pontoon body 1 and a chain link 21. The pontoon body 1 is basically cylindrical in shape, with its top and bottom slightly protruding. The pontoon body 1 is made of corrosion-resistant steel. Specifically, the pontoon body 1 includes an annular outer wall 11, a top bulkhead 12, a bottom bulkhead 13, and steel bulkheads 14. The top bulkhead 12 and the bottom bulkhead 13 are welded and fixed to the upper and lower sides of the outer wall 11, respectively. Inside the outer wall 11, several steel bulkheads 14 are provided. These steel bulkheads 14 extend radially... Extending and evenly distributed, the steel bulkhead 14 is welded and fixed to the inner wall of the outer wall 11 of the pontoon. The upper end of the steel bulkhead 14 is welded to the top bulkhead 12, and the lower end is welded to the bottom bulkhead 13. The steel bulkhead 14 divides the internal space enclosed by the outer wall 11, top bulkhead 12, and bottom bulkhead 13 of the pontoon into several compartments 15. This multi-compartment structure not only improves the overall stability and anti-sinking ability of the pontoon but also provides a reliable structural support foundation for key connecting components. Several chain links 21 are provided on the bottom bulkhead 13 and correspondingly welded to the bottom of the bottom bulkhead 13 and the bottom of the steel bulkhead 14. Because the steel bulkhead 14 itself has high structural strength and penetrates the interior of the pontoon, using it as the welding base for the chain links 21 can significantly enhance the load-bearing capacity of the connection. When under stress, the steel bulkhead 14 acts as a "reinforcing rib," effectively dispersing the tensile force, torsional load, and impact stress transmitted by the anchor chain, preventing stress concentration that could lead to weld cracking.

[0021] Furthermore, four steel bulkheads 14 are provided and welded together in a cross shape. These four cross-shaped steel bulkheads 14 form four symmetrical sealed compartments 15 inside the pontoon, improving the rigidity and deformation resistance of the overall structure, and providing four evenly distributed high-strength welded support points for the chain links 21. Furthermore, four chain links 21 are provided on the bottom bulkhead 13 and welded to the bottom of the four steel bulkheads 14 respectively, achieving multi-point stress distribution.

[0022] Among them, the mooring link 21 is U-shaped, and the two ends of the mooring link 21 pass through the bottom bulkhead 13 and are welded to the bottom of the steel bulkhead 14, so that the force of the mooring link 21 is directly transmitted to the overall skeleton structure of the float through the bulkhead, forming an efficient and stable force transmission path. This design makes full use of the role of the steel bulkhead 14 as an "in-house reinforcing rib", which significantly improves the tensile, torsional and fatigue resistance of the connection parts.

[0023] To further enhance the reliability of the connection, an inner welded pressure plate 22 and an outer welded pressure plate 23 are provided on the tethering link 21. The inner welded pressure plate 22 and the outer welded pressure plate 23 are fixed to the tethering link 21 and welded to the inner and outer sides of the bottom bulkhead 13 respectively, forming a "clamping" composite welded structure. This structure significantly increases the welding area and connection rigidity, effectively preventing the tethering link 21 from loosening, pulling out, or cracking the weld under long-term alternating loads, while also improving the local sealing and structural strength of the bottom bulkhead 13.

[0024] Furthermore, a structural reinforcing plate 24 is welded and fixed between the two ends of the chain link 21. The structural reinforcing plate 24, the inner welded pressure plate 22, and the steel partition plate 14 are also welded and fixed together. The structural reinforcing plate 24 laterally connects the two ends, which helps to suppress the lateral expansion, deformation, and displacement of the U-shaped ring under stress, thereby improving its overall rigidity and load-bearing capacity. The presence of the structural reinforcing plate 24 also helps to evenly distribute stress, reduce stress concentration at the weld root, delay the occurrence of fatigue damage, and further improve the service life and safety of the chain link 21.

[0025] In this utility model, four lifting rings 3 are provided on the top bulkhead 12. The structure of the lifting rings 3 is the same as that of the chain rings 21. The four lifting rings 3 are welded and fixed to the top of the four steel bulkheads 14 respectively. The lifting rings 3 are used to improve the lifting safety of the floats during installation, maintenance and recovery.

[0026] It should also be noted that the terms used in this utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
