Benefits of technology

[0022] This invention provides a fender device that, while meeting the layout requirements of a tugboat's main deck, positions the hull bulwark inside the main deck to form an installation angle with the hull plating. The fender body is then installed within this angle, resting against the hull bulwark and receiving auxiliary support from the main deck, rather than solely relying on the connection structure between the fender body and the hull bulwark. This significantly improves reliability, reduces friction between the connection structure and the hull plating, protects the hull from frictional damage by the fender body, and minimizes the risk of long-term damage to the fender body. Considering the possibility of deformation, the installation of the fender body is comprehensively considered in conjunction with the hull structure. This satisfies both the strength requirements of the hull structure and the installation requirements of the fender body. In addition, the two ends of the fender body are connected to the hull bulwark using end connectors. The connection at both ends pre-fixes the fender body and the hull bulwark in the installation angle. Then, several cylindrical connectors are connected one-to-one in the annular groove of the fender body, and the two ends of the cylindrical connectors are connected to the hull bulwark. This ensures that the fender body is tightly attached to the hull bulwark along the line of the hull bulwark, resulting in good connection stability.

Description

Technical Field

[0001] This invention relates to the field of marine technology, and in particular to a fender device and a ship. Background Technology

[0002] Fenders, also known as ship guards, are elastic buffer devices used on the edges of docks or ships. Made of wood, steel, or rubber, fenders primarily mitigate the impact forces between ships and docks or other vessels during berthing or mooring, reducing or eliminating damage to both. Furthermore, fenders improve a ship's stability and maneuverability, minimizing the impact on the ship in the marine environment. Tugs, as highly functional vessels for towing, ship rescue, coastal towing, and firefighting operations, are equipped with fenders running from stern to bow on the top side of the hull above the design waterline, near the deck, to ensure that the hull does not directly collide with other vessels during operations.

[0003] Currently, ship fenders are installed on the outermost part of the hull to protect the vessel. However, the outer plating has a linear shape, especially when the bow and stern areas are relatively large. Directly welding plates or fasteners to the outer plating for installation and positioning is difficult, and modifications after welding can damage the hull and paint. Furthermore, because fenders are elastic, the steel cables and chains used for securing them can loosen over time, causing friction or collisions with the hull plating and resulting in damage. Therefore, there is an urgent need to design a new fender system and vessel to address these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a fender device and a ship to solve the technical problems of difficult installation and positioning of fenders, inconvenience of maintenance or replacement, and easy damage to the hull shell with long-term use.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A fender device, wherein the main deck of a ship and the hull bulwark form an installation angle along the outer edge of the ship, the fender device comprising:

[0007] The fender body is a cylindrical structure. The fender body is located within the installation angle. The fender body has an annular groove on its periphery. Several annular grooves are arranged along the axial direction of the fender body.

[0008] End connectors, respectively disposed at both ends of the fender body, the end connectors passing through the hull bulwark and connecting to the inner side of the hull bulwark; and

[0009] A plurality of cylindrical connectors are provided, each of which is wound around the annular groove of the fender body in a corresponding manner. The two ends of the cylindrical connectors penetrate the hull bulwark and are respectively connected to the main deck and the hull bulwark.

[0010] As a preferred embodiment of the fender device, a through hole is provided on the hull bulwark, and the end connector includes:

[0011] A chain, one end of which is located at the center of the end face of the fender body, and the other end is detachably connected to the hull bulwark through the through hole.

[0012] As a preferred embodiment of the fender device, the installation positions of the chain and the hull bulwark are perpendicular to the center of the end face of the fender body and form a vertical line, and the through hole is opened along the vertical line.

[0013] As a preferred embodiment of the fender device, a transverse reinforcing rib is provided on the inner side of the hull bulwark, and a first adjusting bolt is provided on the transverse reinforcing rib along the vertical line. A first shackle is provided at the end of the first adjusting bolt, and the chain is detachably connected to the first shackle.

[0014] As a preferred embodiment of the fender device, a tube fixed to the hull bulwark is provided on the outer side of the hull bulwark along the through hole.

[0015] As a preferred embodiment of the fender device, the hull bulwark has first and second mounting holes arranged vertically, the main deck has a first eye plate corresponding to the first mounting hole, and the inner side of the hull bulwark has a second eye plate corresponding to the second mounting hole. The cylindrical connector includes:

[0016] A steel wire rope, wherein the two ends of the steel wire rope are respectively disposed on the first eye plate and the second eye plate, and at least one end of the two ends of the steel wire rope is provided with a second adjusting bolt, and the end of the second adjusting bolt is provided with a second shackle, and the steel wire rope is detachably connected to the second shackle.

[0017] As a preferred embodiment of the fender device, the axial direction of the second adjusting bolt is tangent to the fender body.

[0018] As a preferred embodiment of the fender device, a first round steel bar is provided at the end of the tube body and along the edges of the first and second mounting holes.

[0019] As a preferred embodiment of the fender device, a second round steel bar is provided at the corner edge of the main deck and the hull hull plating, and the fender body is in contact with the second round steel bar.

[0020] A vessel includes a hull bulwark, a main deck, hull plating, and the aforementioned fenders. The hull plating surrounds the perimeter of the main deck and is located at the bottom of the main deck. The hull bulwark surrounds the top of the main deck. The hull plating and the hull bulwark are spaced apart to form the installation angle for mounting the fenders.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a fender device that, while meeting the layout requirements of a tugboat's main deck, positions the hull bulwark inside the main deck to form an installation angle with the hull plating. The fender body is then installed within this angle, resting against the hull bulwark and receiving auxiliary support from the main deck, rather than solely relying on the connection structure between the fender body and the hull bulwark. This significantly improves reliability, reduces friction between the connection structure and the hull plating, protects the hull from frictional damage by the fender body, and minimizes the risk of long-term damage to the fender body. Considering the possibility of deformation, the installation of the fender body is comprehensively considered in conjunction with the hull structure. This satisfies both the strength requirements of the hull structure and the installation requirements of the fender body. In addition, the two ends of the fender body are connected to the hull bulwark using end connectors. The connection at both ends pre-fixes the fender body and the hull bulwark in the installation angle. Then, several cylindrical connectors are connected one-to-one in the annular groove of the fender body, and the two ends of the cylindrical connectors are connected to the hull bulwark. This ensures that the fender body is tightly attached to the hull bulwark along the line of the hull bulwark, resulting in good connection stability.

[0023] The present invention provides a type of vessel in which the fender body is installed within the installation angle between the hull bulwark and the outer hull plating, and the fender body rests against the hull bulwark. The fender body is further supported by the main deck, rather than by the connection structure between the fender body and the hull bulwark, which greatly improves the reliability.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0036] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0039] Existing ship fenders are installed on the outermost part of the hull to protect the ship. However, the outer plating has a linear shape, especially when the bow and stern areas of the ship have a large linear shape. The method of directly welding the clamps or fixing buckles to the outer plating is difficult to install and position. Modifications after welding will damage the hull and paint. In addition, since the fenders are elastic, after long-term use, the steel wire ropes and chains used for the fender fixing locks will loosen, causing the steel wire ropes or chains to rub or collide with the hull plating, which will damage the hull.

[0040] To solve the above problems, such as Figures 1-2 As shown, this embodiment provides a ship, which includes a hull bulwark 100, a main deck 200, a hull plating 300, and fender devices. The hull plating 300 surrounds the perimeter of the main deck 200 and is located at the bottom of the main deck 200. The hull bulwark 100 surrounds the top of the main deck 200. The hull plating 300 is located on the inner side of the main deck 200 and is spaced apart from the hull bulwark 100 to form an installation angle 400 for the installation of fender devices.

[0041] It should be noted that this embodiment uses a tugboat as an example, but is not limited to tugboats. First, considering that most fender devices are installed on the outermost side of the hull plating 300 and need to be above the ship's draft to meet the usage requirements, since the main deck 200 and above of the tugboat are all hull bulwarks 100 of the ship, and the hull bulwarks 100 are secondary structures of the ship, having little impact on the overall longitudinal strength of the ship, the hull bulwarks 100 are an open-air auxiliary safety structure of the ship, mainly to protect the safety of the crew and prevent items on the main deck 200 from falling into the water.

[0042] Therefore, while meeting the layout requirements of the tugboat's main deck 200, the hull bulwark 100 is positioned inside the main deck 200 to form an installation angle 400 with the hull plating 300 (see...). Figure 3 The fender device is installed within an installation angle of 40°, resting against the hull bulwark 100 and further supported by the main deck 200, rather than solely by the connection structure between the fender device and the hull bulwark 100. This significantly improves reliability and reduces friction between the fender device and the hull hull plating 300 should the connection structure (i.e., wire ropes and chains) loosen. This ensures the hull shell is not damaged by friction from the fender device and reduces the possibility of deformation after long-term use. In summary, by comprehensively considering the installation of the fender body 1 in conjunction with the hull structure, both the strength requirements of the hull structure and the installation requirements of the fender device are met.

[0043] Specifically, such as Figures 3-5 As shown, this embodiment also provides a fender device, which includes a fender body 1, an end connector, and a cylindrical connector. The fender body 1 is a cylindrical structure made of rubber. Rubber has good comprehensive properties, with good elasticity and compressive deformation, which can effectively buffer the impact of the ship. Of course, the fender body 1 can also be made of wood or steel, and this embodiment does not limit it. The fender body 1 is located within the installation angle 40° and can be locked in the installation angle 40°. The fixed end of the cylindrical fender body 1 abuts against the hull bulwark 100, and the free edge is flush with the outer plate of the hull bulwark 100, so that the fender body 1 and the hull bulwark 100 transition perfectly, with a beautiful and layered appearance.

[0044] Furthermore, a steel wire (not shown in the figure) is fixed at the center of the axis of the fender body 1. The steel wire enhances the overall strength of the fender body 1. Two end connectors are provided, which are respectively connected to the two ends of the steel wire. The other end of the end connector, away from the fender body 1, passes through the hull bulwark 100 and connects to the inner side of the hull bulwark 100. The fender body 1 is placed directly within the aforementioned installation angle 400, and the two ends of the fender body 1 are connected to the hull bulwark 100 using the end connectors. This connection at both ends pre-fixes the fender body 1 to the hull bulwark 100 within the installation angle 400, improving the installation efficiency of the fender device.

[0045] Optionally, such as Figure 2 As shown, a through hole is provided on the hull bulwark 100. The through hole is located on the two opposite inner sidewalls with an installation angle of 40°. The end connector extends through the through hole to the inner side of the hull bulwark 100 for installation and fixation. A tube 4 fixed to the hull bulwark 100 is provided on the outer side of the hull bulwark 100 along the through hole. The tube 4 covers the end connector around the perimeter of the through hole so that the end connector is not exposed, reducing the impact of the external environment on the end connector, making the ship more aesthetically pleasing and strengthening its structure.

[0046] In this embodiment, as Figure 3 As shown, the end connector includes a chain 2, a first adjusting bolt 21, and a first shackle 22. One end of the chain 2 is located at the center of the end face of the fender body 1, i.e., at the end of the steel wire. The other end of the chain 2 passes through a through hole and is detachably connected to the hull bulwark 100. To achieve this detachable connection, a transverse reinforcing rib 9 is provided on the inner side of the hull bulwark 100. The first adjusting bolt 21 is installed on the transverse reinforcing rib 9, and the end of the first adjusting bolt 21 is provided with the first shackle 22. The chain 2 is detachably connected to the first shackle 22, thus facilitating subsequent maintenance and replacement of the fender body 1. Since both the first adjusting bolt 21 and the first shackle 22 are located on the inner side of the hull bulwark 100, operators can perform adjustments while standing on the main deck 200, making the operation more convenient. For example, during use, the rubber fender body 1 will inevitably deform over time. At this point, the chain 2 can be tightened simply by standing on the main deck 200 and turning the first adjusting bolt 21, without having to wait until docking to adjust the fender body 1, making maintenance very convenient. Furthermore, reinforcing plates can be added to the sides of the transverse reinforcing ribs 9 to locally thicken the entire structure, adapting to the stress on the fender body 1 within the transverse reinforcing ribs 9 and making the connection more reliable.

[0047] In addition, to reduce the damage caused by contact friction between the end of the fender body 1 and the chain 2, the installation positions of the chain 2 and the hull bulwark 100 are perpendicular to the center of the end face of the fender body 1 and form a vertical line. The through hole is opened along the vertical line, and the first adjusting bolt 21 is also set along the vertical line. At the same time, the first adjusting bolt 21 can adjust the tension of the chain 2 along the vertical line. To further reduce friction damage, a first round steel 10 is also set on the edge of the end of the tube 4 to protect the chain 2 and extend its service life.

[0048] Furthermore, such as Figure 4 and Figure 5 As shown, annular grooves 101 are provided around the periphery of the fender body 1. Several annular grooves 101 are arranged along the axial direction of the fender body 1. Each cylindrical connector is correspondingly wound around the annular groove 101 of the fender body 1. The two ends of the cylindrical connectors penetrate the hull bulwark 100 and are respectively connected to the main deck 200 and the hull bulwark 100. By using several cylindrical connectors correspondingly connected to the annular grooves 101 of the fender body 1 and ensuring that the two ends of the cylindrical connectors are in contact with the hull bulwark 100, the fender body 1 is tightly attached to the hull bulwark 100 along the line of the hull bulwark 100, resulting in good connection stability.

[0049] In this embodiment, the hull bulwark 100 has a first mounting hole 7 and a second mounting hole 8 arranged vertically. The first mounting hole 7 and the second mounting hole 8 are symmetrically arranged in the horizontal direction and are both U-shaped. The main deck 200 is provided with a first eye plate 5 corresponding to the first mounting hole 7. The inner side of the hull bulwark 100 is provided with a second eye plate 6 corresponding to the second mounting hole 8. The cylinder connector includes a steel wire rope 3. The two ends of the steel wire rope 3 are respectively provided on the first eye plate 5 and the second eye plate 6. At least one end of the two ends of the steel wire rope 3 is provided with a second adjusting bolt 31. The end of the second adjusting bolt 31 is provided with a second shackle 32. The steel wire rope 3 is detachably connected to the second shackle 32.

[0050] Preferably, one end of the wire rope 3 passes directly through the first mounting hole 7 and connects to the first eye plate 5. The other end of the wire rope 3 is detachable from the second shackle 32 and passes through the second mounting hole 8 via the second adjusting bolt 31, then connects to the second eye plate 6. To reduce damage caused by contact friction between the second mounting hole 8 and the wire rope 3, the axial direction of the second adjusting bolt 31 is tangent to the fender body 1. Furthermore, a first round steel bar 10 can be provided on the edges of the first mounting hole 7 and the second mounting hole 8 to protect the wire rope 3 and extend its service life. In other embodiments, the second adjusting bolt 31 and the second shackle 32 can be provided at both ends of the wire rope 3, or the second adjusting bolt 31 and the second shackle 32 can be provided at one end connected to the first eye plate 5, and the other end can be directly fixed to the second eye plate 6. This embodiment does not specifically limit this. Since the second adjusting bolt 31 and the second shackle 32 are both located inside the hull bulwark 100, the operator can perform the adjustment while standing on the main deck 200, making the operation more convenient.

[0051] In addition, in order to protect the fender body 1, a second round steel bar 11 is provided at the corner edge of the main deck 200 and the outer plate 300, and the fender body 1 is in contact with the second round steel bar 11.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
