Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a yacht deck bulwark bollard structure, and a boat having a yacht deck bulwark bollard structure. Background Technology

[0002] With the rapid development of the yacht industry, yacht design has placed higher demands on mooring devices in the deck bulwark area. These devices must not only meet the requirements of high-intensity mooring functions, but also take into account the efficient use of space, the overall aesthetic appeal, and the protective performance of the bulwarks.

[0003] Currently, common yacht bollard installation methods fall into two main categories: one is to expose the bollard directly on the deck surface. While this design facilitates cable handling, it occupies valuable deck space, and personnel are prone to tripping over protruding bollards while walking or working, posing a safety hazard. The other is to install the bollard on the outer surface of the bulwark. Although this avoids occupying deck space, it disrupts the overall streamlined appearance of the yacht—the bollard protruding from the bulwark clashes with the streamlined hull shape, affecting visual harmony. More seriously, the cables of exposed bollards are prone to direct friction with the bulwark during retrieval and deployment, causing the bulwark coating to peel or the material to be scratched. Over time, this weakens the structural integrity of the bulwark and reduces the yacht's aesthetic appeal.

[0004] Therefore, there is an urgent need for an integrated, concealed yacht deck bulwark bollard structure to solve the above problems. Utility Model Content

[0005] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a yacht deck bulwark bollard structure. Through a concealed integrated design, the bollards and guide cables are hidden inside the deck bulwark, which does not occupy deck space. Furthermore, the deck bulwark and deck work together to improve mooring strength, and it also has the advantages of preventing tripping and having a smooth and beautiful appearance, thus achieving a unity of function, strength and aesthetics.

[0006] This utility model also proposes a vessel having the above-mentioned yacht deck bulwark bollard structure.

[0007] A yacht deck bulwark bollard structure according to this utility model includes: The cable guide sleeve is fixedly installed inside the deck bulwark; The bollard has a base plate fixedly installed at its bottom. The base plate is welded and fixed to the guide cable sleeve. Bolts are inserted through the base plate and are sequentially inserted through the deck bulwark and the deck to drive the guide cable sleeve to be fixed to the deck bulwark and the deck.

[0008] The yacht deck bulwark bollard structure according to this utility model has at least the following beneficial effects: it completely changes the drawback of traditional bollards being exposed on the deck or deck bulwark surface, integrating the guide sleeve and bollard completely into the deck bulwark cavity, without occupying deck activity space, and avoiding the safety hazard of personnel tripping over protruding bollards when walking; at the same time, the concealed structure keeps the yacht bulwark's appearance streamlined and smooth, integrating with the overall shape of the hull, significantly improving the visual coordination and aesthetic value of the yacht's high-end design, and conforming to the modern yacht's pursuit of "function hidden under aesthetics"; furthermore, the cable tension on the bollard is transferred to the deck bulwark and the deck through bolts, forming a collaborative force-bearing system between the originally independent deck bulwark and deck structure. Compared with the weak connection of single-point welding or surface fixing in the prior art, this double fixing mechanism of welding and bolt penetration greatly improves the structure's pull-out resistance and shear strength, especially under extreme dynamic load conditions such as typhoons, effectively avoiding loosening, deformation or even failure caused by local stress concentration, and ensuring the reliability of mooring function.

[0009] According to some embodiments of the present invention, a yacht deck bulwark bollard structure is provided, wherein there are two bollards, which are symmetrically arranged on both sides of the bottom plate; And / or, the cable guide sleeve, the cable bollard, the base plate, and the bolts are all made of stainless steel; And / or, the bollard is welded and fixed to the base plate.

[0010] According to some embodiments of the present invention, a yacht deck bulwark bollard structure is provided, wherein there are multiple bolts, and the multiple bolts are distributed on the base plate.

[0011] According to some embodiments of the present invention, a yacht deck bulwark bollard structure is provided, wherein the angle between the deck bulwark and the deck is A, satisfying: 85°≤A≤95°.

[0012] According to some embodiments of this utility model, a yacht deck bulwark bollard structure is provided, wherein a metal embedded plate is fixedly installed below the guide cable sleeve, and some of the bolts pass through the metal embedded plate to enhance the connection strength of the bolts.

[0013] According to some embodiments of the present invention, a yacht deck bulwark bollard structure is provided with an annular portion on the side of the guide cable sleeve facing away from the bollard. The annular portion can cover at least part of the deck bulwark to prevent the cable from scratching the deck bulwark.

[0014] According to some embodiments of this utility model, a yacht deck bulwark bollard structure is provided with sealant to seal the joint between the annular portion and the deck bulwark.

[0015] According to some embodiments of this utility model, in a yacht deck bulwark bollard structure, the fitting length between the bolt and the deck is B, which satisfies: B≥20mm.

[0016] According to some embodiments of this utility model, a yacht deck bulwark bollard structure is provided, wherein the base plate is provided with countersunk holes, and the head of the bolt is placed in the countersunk holes.

[0017] The boats described in this utility model include a yacht deck bulwark bollard structure as described in this utility model.

[0018] The boat described in this utility model has at least the following beneficial effects: the guide sleeve and bollard hidden in the deck bulwark do not occupy deck space, improving the safety of internal boat operations. The stainless steel material and metal embedded plate design ensure the structure's corrosion resistance in the seawater environment, while the annular part can protect the deck bulwark from cable scratches. In addition, the multiple bolts distributed and bolts with sufficient matching length strengthen the coordinated fixing strength of the deck bulwark and the deck, thereby making the boat's mooring system more reliable, space utilization more efficient, and appearance more beautiful. It is especially suitable for yachts, small boats, etc., which have high requirements for both functionality and aesthetics, expanding the application range and market value of the bollard structure.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0027] Therefore, such as Figures 1 to 4As shown, this utility model proposes a yacht deck bulwark bollard structure, including a guide sleeve 300 fixedly installed in the deck bulwark 100 and a bollard 400 fixedly connected to the guide sleeve 300. Specifically, a base plate 500 is fixedly installed at the bottom of the bollard 400. The base plate 500 is welded and fixed to the guide sleeve 300. Bolts 510 are passed through the base plate 500. The bolts 510 are sequentially passed through the deck bulwark 100 and the deck 200 to drive the guide sleeve 300 to be fixed to the deck bulwark 100 and the deck 200. It should be noted that this design completely overcomes the drawbacks of traditional bollards 400 being exposed on the surface of deck 200 or deck bulwark 100. The guide sleeve 300 and bollard 400 are fully integrated into the cavity of deck bulwark 100, without occupying the activity space on deck 200, thus avoiding the safety hazard of personnel tripping over protruding bollards 400 while walking. At the same time, the concealed structure maintains the streamlined and fluid appearance of the yacht's bulwark, blending seamlessly with the overall hull shape, significantly enhancing the visual harmony and aesthetic value of the yacht's high-end design, aligning with the modern yacht's pursuit of "function hidden beneath aesthetics." Furthermore, the cable tension on the bollard 400 is transferred to the deck bulwark 100 and deck 200 through bolts 510, so that the originally independent deck bulwark 100 and deck 200 structures form a cooperative force-bearing system. Compared with the weak connection of single-point welding or surface fixing in the existing technology, this double fixing mechanism of welding and bolt 510 through-hole greatly improves the structural pull-out force and shear strength. Especially under extreme dynamic load conditions such as typhoons, it can effectively avoid loosening, deformation or even failure caused by local stress concentration, and ensure the reliability of mooring function.

[0028] Refer to Figure 1 , Figure 3 and Figure 4In some embodiments of this utility model, there are two bollards 400, symmetrically arranged on both sides of the bottom plate 500. When the cable is used in conjunction with the two bollards 400, the cable tension can be evenly distributed to the left and right sides of the bottom plate 500, avoiding the twisting or tilting of the bottom plate 500 caused by unilateral force, making the fixation of the bottom plate 500 to the guide sleeve 300 more stable. At the same time, when multiple cables are used in conjunction with the two bollards 400, the symmetrical layout adapts to the need for simultaneous mooring of multiple cables, improving the space utilization efficiency of the deck bulwark 100 area. Optionally, the guide sleeve 300, bollards 400, bottom plate 500, and bolts 510 are all made of stainless steel. Utilizing the seawater corrosion resistance of stainless steel, it is ensured that each component will not rust during long-term use in the environment of the deck bulwark 100 in contact with seawater, maintaining structural stability. Moreover, the uniform material makes the overall appearance of the guide sleeve 300, bollards 400, bottom plate 500, and deck bulwark 100 more coordinated, and will not damage the overall aesthetics of the yacht due to differences in materials. In some embodiments, the bollard 400 is welded and fixed to the base plate 500, which can directly transfer the force of the bollard 400 to the base plate 500, forming a rigid connection, eliminating the gap of the separate assembly, and allowing the base plate 500 to more effectively transfer the tension of the bollard 400 to the deck bulwark 100 and the deck 200 through the bolts 510. This strengthens the structural strength of the bollard 400 and the guide sleeve 300 as a whole, laying the foundation for the reliability of the entire bollard 400 structure.

[0029] Refer to Figure 4 In some embodiments of this utility model, there are multiple bolts 510, which are distributed on the bottom plate 500. The force is evenly transmitted to the deck bulwark 100 and deck 200 by these multiple distributed bolts 510. Each bolt 510 bears only a portion of the tensile force, avoiding the risk of loosening or breakage due to stress concentration at a single point. Furthermore, the distributed bolts 510 have a larger contact area with the deck bulwark 100 and deck 200, allowing the deck bulwark 100 and deck 200 to more fully cooperate in bearing the tensile force. Especially under extreme dynamic loads such as typhoons, this effectively suppresses deformation of the bottom plate 500 or loosening of the bolts 510, significantly improving the stability and fatigue resistance of the structure in which the cable guide sleeve 300 is fixed to the deck bulwark 100 and deck 200 via the bottom plate 500, ensuring the reliability of long-term mooring.

[0030] Furthermore, in some embodiments of this utility model, the angle between the deck bulwark 100 and the deck 200 is A, satisfying: 85°≤A≤95°. That is, the deck bulwark 100 and the deck 200 are arranged at approximately 90°, forming a near-right-angle transition structure. This ensures that the cable guide sleeve 300 can be completely hidden within the deck bulwark 100, i.e., not exposed within the deck bulwark 100, maintaining the streamlined appearance of the deck bulwark 100, while also allowing the bolts 510 passing through the bottom plate 500 to sequentially pass through the deck bulwark 100 and the deck 200 along a relatively straight path.

[0031] In some embodiments of this utility model, such as Figure 2 As shown, a metal embedded plate 110 is fixedly installed below the guide sleeve 300 on the deck bulwark 100. Some bolts 510 pass through the metal embedded plate 110 to enhance the connection strength of the bolts 510. It can be understood that the high strength characteristics of the metal embedded plate 110 are used to enhance the connection between the bolts 510 and the deck bulwark 100. When the bolts 510 pass through the metal embedded plate 110, they can be fixed by tapping on the metal embedded plate 110, avoiding structural damage caused by directly tapping on the wooden or composite material deck bulwark 100. At the same time, the metal embedded plate 110 increases the contact area between the bolts 510 and the deck bulwark 100, which greatly improves the shear resistance and pull-out resistance of the bolts 510, ensuring that the structure of the guide sleeve 300 fixed to the deck bulwark 100 and the deck 200 through the base plate 500 and the bolts 510 will not fail under extreme tensile forces. Furthermore, the fixed position of the metal embedded plate 110 is located within the deck bulwark 100, which does not affect the usable space of the deck 200, but strengthens the strength of the deck bulwark 100 as a fixed carrier, allowing the deck bulwark 100 and the deck 200 to more reliably cooperate in supporting the guide cable sleeve 300. Further, in some embodiments of this utility model, an annular portion 310 is provided on the side of the guide cable sleeve 300 facing away from the bollard 400. The annular portion 310 covers at least part of the deck bulwark 100, so that the cable only contacts the annular portion 310 during winding and unwinding, rather than directly rubbing against the deck bulwark 100. This fundamentally avoids the cable scratching the coating or material of the deck bulwark 100, protecting the appearance integrity and structural durability of the deck bulwark 100. Optionally, the joint between the annular portion 310 and the deck bulwark 100 is sealed with sealant. On the one hand, it can prevent seawater and rainwater from seeping into the interior of the deck bulwark 100 during the cable handling, thus preventing the metal embedded plate 110 or bolts 510 from rusting due to moisture and protecting the structural components inside the deck bulwark 100. On the other hand, it can enhance the adhesion between the annular part 310 and the deck bulwark 100, thus preventing the annular part 310 from deforming due to yacht vibration or cable tension, ensuring that the annular part 310 continuously covers the protective function of the deck bulwark 100. In addition, the flexible properties of the sealant can also buffer the micro-vibrations generated by the cable friction against the annular part 310, reduce the hard collision between the annular part 310 and the deck bulwark 100, further protect the deck bulwark 100 from indirect damage, and maintain the long-term reliability and appearance integrity of the structure in which the cable guide sleeve 300 is fixedly installed inside the deck bulwark 100.

[0032] Refer to Figure 2In some embodiments of this utility model, the mating length between the bolt 510 and the deck 200 is B, which satisfies: B≥20mm. Sufficient anchoring depth ensures that the bolt 510 has sufficient tightening force within the deck 200. After the bolt 510 passes through the base plate 500 and the deck bulwark 100 in sequence, the longer mating length allows the thread of the bolt 510 to fully engage with the concrete, metal, or composite material layer of the deck 200, significantly improving the pull-out resistance of the bolt 510. This prevents the bolt 510 from being pulled out of the deck 200 due to excessive cable tension, ensuring that the guide sleeve is fixed to the deck bulwark 100 and the deck 200 structure through the base plate 500 and the bolt 510, thus strengthening the connection strength of the entire structure. Furthermore, the base plate 500 is provided with countersunk holes 501, and the head of the bolt 510 is placed in the countersunk holes 501, so that the bolt 510 is flush with the surface of the base plate 500 after assembly, avoiding the protruding head of the bolt 510 from snagging on objects. For example, the flat upper surface of the base plate 500 can reduce the frictional resistance between the cable and the base plate 500 when the cable is being wound up or down, making the cable movement smoother. Moreover, the structure without protrusions on the surface better meets the yacht's requirements for a clean and aesthetically pleasing design in the deck bulwark 100 area, further enhancing the stability and practicality of the structure in which the cable guide sleeve 300 is fixed to the deck bulwark 100 and deck 200 through the base plate 500 and bolts 510.

[0033] The vessel according to an embodiment of the present invention includes a yacht deck bulwark bollard structure according to an embodiment of the present invention.

[0034] According to the embodiments of this utility model, the boat adopts a yacht deck bulwark bollard structure of this utility model. The guide sleeve 300 and bollard 400 hidden in the deck bulwark 100 do not occupy the space of the deck 200, improving the safety of internal activities of the boat. The stainless steel material and the metal embedded plate 110 design ensure the corrosion resistance of the structure in the seawater environment, while the annular part 310 can protect the deck bulwark 100 from being scratched by the cable. In addition, the multiple bolts 510 are distributed and the bolts 510 with sufficient matching length strengthen the cooperative fixing strength of the deck bulwark 100 and the deck 200. Thus, the mooring system of the boat is more reliable, the space utilization is more efficient, and the appearance is more beautiful. It is especially suitable for yachts and small boats with high requirements for both functionality and aesthetics, expanding the application scope and market value of the bollard 400 structure.

[0035] Other configurations and operations of the boats according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
