Description

Technical Field

[0001] The invention relates to the technical field of ship anti-collision, and in particular to an adjustable ship peripheral anti-collision component. Background Art

[0002] When a ship docks, a variety of anti-collision devices are used to ensure the safety of the ship and the berth. These devices are designed to absorb the impact energy when the ship docks and reduce damage to the ship and berth.

[0003] There are various styles of ship fenders, each with its own advantages and disadvantages. Their main function is to absorb the impact energy of the ship when it docks through its elastic deformation, protecting the ship and berth structure from damage.

[0004] The airbag fender is also one of the commonly used anti-collision components. It mainly uses the elasticity of air to absorb energy. It has the characteristics of large energy absorption, large contact area when docking, and strong adaptability. The airbag fender is compressed and deformed by the air filled inside when it is impacted, thereby effectively absorbing the energy generated when the ship is docked and protecting the hull and dock facilities from damage. Since the airbag fender is relatively large in size and soft in surface, the contact area with the ship and the dock is also increased accordingly, further dispersing the impact force and improving the protection effect.

[0005] However, there are still some problems with the airbag fender. Although it can produce deformation and absorb energy when it is squeezed with the dock, in harsh environments, especially when there is strong wind, the ship will continue to move with the waves, showing a wave-like movement. For this reason, the ship and the dock will not only produce a squeezing effect on the airbag fender, but also a kneading effect. The airbag fender is kneaded, causing a greater degree of wear on its outer wall. The greater the squeezing effect, the greater the degree of wear, and the airbag fender is more easily damaged and needs to be replaced regularly.

[0006] In addition, the ship is in an oblique squeezed state between the ship and the dock, and does not move in a straight line along the dock. The non-vertical impact will cause the airbag fender to be subjected to lateral force, thereby generating a large shear force. This shear force may damage the structure of the airbag fender, especially when the shear force exceeds the bearing capacity of the airbag fender, the airbag fender may be torn or damaged. In the case of non-vertical impact, the compression deformation of the airbag fender may become uneven, resulting in a reduction in the energy absorption effect of the airbag fender, because some areas may be over-compressed and lose elasticity, while other areas may not be fully compressed. The uneven compression deformation affects the service life and stability of the airbag fender. Summary of the invention

[0007] The object of the present invention is to provide an adjustable ship peripheral anti-collision component to solve the problems raised in the above background technology.

[0015] Furthermore, an annular opening is provided on the outer side of the roller near both ends, and the annular opening is located on the outer side of the arc frame. A metal ring layer is clamped in the annular opening, and the metal ring layer is in contact with the outer side of the arc frame.

[0016] Furthermore, the metal ring layer is provided in two halves, and the two halves of the metal ring layer are fixed by bolts.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] See also Figure 1-Figure 10The present invention provides a technical solution: an adjustable ship external anti-collision component, comprising a plurality of airbag-type fender bodies 1 arranged and installed on the outside of the ship. After the plurality of airbag-type fender bodies 1 are installed, when the ship is docked at various positions, they can be protected by the airbag-type fender bodies 1 to avoid collision with the ship itself. The airbag-type fender body 1 comprises a fixing plate 11, a supporting frame 12, a moving part 2 and an airbag body 3;

[0038] like Figure 2 As shown, two support frames 12 are provided, and the two support frames 12 are both fixed on the outside of the fixing plate 11, and the fixing plate 11 is fixed on the outside of the ship. The fixing plate 11 plays a connecting role, and the two support frames 12 mainly play a supporting role, and avoid the generation of gaps between the moving part 2 and the ship, avoid unnecessary deformation, and directly act on the ship with the impact force. The moving part 2 is clamped between the two support frames 12, and its orientation can be changed. The airbag body 3 is installed on the inner side of the moving part 2, and is used to absorb energy by squeezing with the outside world. The airbag body 3 is limited by the moving part 2, so that the airbag body 3 can be vertically squeezed with the dock to reduce shear force. When the ship is tilted, it is ensured that the airbag body 3 on its outside is vertically squeezed with the dock.

[0039] like Figure 3 As shown, the moving part 2 includes an arc frame 21 and a rectangular sealing layer 22, the two support frames 12 are triangular in shape, and arc-shaped clamping openings 13 are provided on opposite sides of the two support frames 12. The arc frame 21 is semicircular and is clamped in two opposite arc-shaped clamping openings 13. The arc frame 21 is clamped by two opposite arc-shaped clamping openings 13. The arc frame 21 is located in the two arc-shaped clamping openings 13 to produce a bias, which is used to change the orientation of the airbag body 3 so that the airbag body 3 acts vertically on the dock. It should also be noted that only the arc-shaped clamping openings 13 are provided on the support frame 12, and the arc frame 21 is clamped in the arc-shaped clamping openings 13 to avoid gaps and deformation. It should also be noted that after the airbag body 3 is deformed, the airbag body 3 will be squeezed with the inner side of the arc frame 21, and the force will be directly applied to the ship to avoid deformation of the arc frame 21.

[0040] like Figure 3 and Figure 4 As shown, two rectangular sealing layers 22 are provided, and the two rectangular sealing layers 22 are both sleeved on the arc frame 21, and the two rectangular sealing layers 22 are respectively fixed to the two ends of the two matching support frames 12, and the rectangular sealing layers 22 are squeezed against the outer wall of the arc frame 21 and the end of the arc-shaped clamp 13. Under the action of the rectangular sealing layers 22, the entry of water into the arc-shaped clamp 13 can be reduced to the greatest extent, and rust in the arc-shaped clamp 13 can be avoided as much as possible.

[0041] like Figure 4As shown, the airbag body 3 is sealed and contains gas inside. The material of the airbag body 3 is rubber. It should be noted that the rubber material has the characteristics of corrosion resistance and wear resistance, so that the rubber airbag can maintain a long service life in the harsh marine environment and reduce the frequency of replacement and maintenance.

[0042] like Figure 4 As shown, a plurality of rollers 32 are provided through the inner side of the arc frame 21, and the plurality of rollers 32 are arranged longitudinally to achieve a supporting function, support the airbag body 3, and increase the supporting area. The airbag body 3 is sleeved on the outer side of the plurality of rollers 32, as shown in FIG. Figure 8 As shown, an inner metal thin layer 31 is adhered to the side of the airbag body 3 that contacts the roller 32 to reduce friction. The inner metal thin layer 31 and the roller 32 are relatively smooth, which minimizes friction and allows the airbag body 3 to rotate along it. The shear force is reduced as much as possible under the action of wind and waves to avoid twisting of the airbag body 3.

[0043] like Figure 5 and Figure 7 As shown, both ends of the inner metal thin layer 31 are provided with rubber support layers 33, and the rubber support layer 33 is sleeved on the outside of the multiple rollers 32, and one side of the rubber support layer 33 is in contact with the inner metal thin layer 31, and the other side is in contact with the inner wall of the arc frame 21, which is used to limit the inner metal thin layer 31. It should be noted that the rubber support layer 33 covers the multiple rollers 32, so that the exposed range of the multiple rollers 32 is reduced, and the range of corrosion of the rollers 32 is reduced. In addition, the inner metal thin layer 31 is also supported so that the position of the inner metal thin layer 31 remains relatively unchanged.

[0044] like Figure 6 As shown, an annular opening 321 is opened on the outer side of the roller 32 near both ends, and the annular opening 321 is located on the outer side of the arc frame 21. A circle of metal ring layer 322 is fixed in the annular opening 321, and the metal ring layer 322 is in contact with the outer side of the arc frame 21. It should be noted that the metal ring layer 322 plays a blocking role to prevent the roller 32 from falling off and also enables the roller 32 to rotate.

[0045] The metal ring layer 322 is provided in two halves, and the two halves of the metal ring layer 322 are fixed by bolts. The two halves of the metal ring layer 322 fit in the annular opening 321 and are fixed by bolts to limit the roller 32. The two halves of the metal ring layer 322 can be removed and the bolts can also be replaced. Even if the bolts are rusted, they can be replaced without affecting the roller 32. The roller 32 does not have a threaded hole, and long-term use can avoid rust and difficulty in removing the bolts.

[0046] like Fig. 9 and Fig.10As shown, the airbag type fender body 1 also includes a lubricating portion 4. The airbag body 3 is deformed by force and squeezes the lubricating portion 4. The lubricating portion 4 is subjected to the force of the deformation of the airbag body 3, so that the lubricating portion 4 squeezes the lubricating liquid into the arc-shaped clamping opening 13. The lubricating portion 4 includes an arc-shaped plate layer 41, a ring-shaped rubber layer 42, a support spring 43, a liquid inlet pipe 44 and a liquid outlet pipe 45.

[0047] The arc-shaped plate layer 41 is provided with two layers, and the ring-shaped rubber layer 42 is fixedly clamped between the two layers of the arc-shaped plate layers 41. The arc-shaped plate layer 41 on one side is fixed on the inner side of the arc frame 21. The ring-shaped rubber layer 42 has deformation ability. The support spring 43 is fixed between the two layers of the arc-shaped plate layers 41 and is used to restore the two layers of the arc-shaped plate layers 41. The liquid inlet pipe 44 and the liquid outlet pipe 45 are both fixed on the outer side of the ring-shaped rubber layer 42. The liquid inlet pipe 44 and the liquid outlet pipe 45 are both connected to the inside of the ring-shaped rubber layer 42. The liquid inlet pipe 44 and the liquid outlet pipe 45 are both connected with a one-way valve 46, which is used for the liquid inlet pipe 44 to only take in liquid, and the liquid outlet pipe 45 to only The liquid can be discharged, and the liquid inlet pipe 44 extends upward to the ship. The outer end of the liquid outlet pipe 45 is connected to the inside of the arc-shaped clamp 13, and is used to transport the lubricating liquid into the arc-shaped clamp 13. It should be noted that in the process of the lubrication part 4 being subjected to force and not subjected to force alternately, the space between the two layers of the arc-shaped plate layers 41 can change. At the same time, under the action of the one-way valve 46, the lubricating liquid moves from between the two layers of the arc-shaped plate layers 41 to the liquid outlet pipe 45, or moves from the liquid inlet pipe 44 to between the two layers of the arc-shaped plate layers 41. It should also be noted that the liquid inlet pipe 44 extends to the ship and contacts the lubricating liquid to absorb the lubricating liquid.

[0048] The working principle of the present invention is as follows: the fixing plate 11 is installed on the outside of the ship, so that the airbag type fender body 1 is located outside the ship, and is used to generate compression with the dock to achieve the function of protecting the ship.

[0049] When the ship is docked, the airbag body 3 is located between the ship and the dock. The air filled inside is compressed and deformed when impacted, thereby effectively absorbing the energy generated when the ship is docked, protecting the hull and dock facilities from damage, and allowing the ship to dock.

[0050] When the ship is docked in the case of wind and waves, the wind and waves will drive the ship to move up and down, and the wind and waves also have thrust, which increases the difficulty of the ship docking. When the airbag fender body 1 contacts the dock, the airbag body 3 is squeezed with the dock, so that the airbag body 3 is deformed, and the energy generated when the ship docks is effectively absorbed. In addition, the airbag body 3 squeezed by the dock is attached to the dock. Under the action of the up and down movement of the ship, the airbag body 3 rolls along the dock to avoid sliding friction with the dock, so that the airbag body 3 is kept intact as much as possible, and the service life and stability are improved. It should be noted that when the airbag body 3 is squeezed and deformed with the dock, the squeezing area between the dock will increase, and the energy dispersion will be more uniform, thereby reducing the situation of excessive force on a single point, protecting the ship and dock facilities, and achieving a certain degree of angle compensation, so that the ship can dock more smoothly. This feature is particularly important when the wind and waves are large or the docking position of the ship is inaccurate, and can improve the stability and safety of docking.

[0051] It should also be noted that the airbag body 3 is deformed, and the friction is reduced to a certain extent through the squeezing of the inner metal thin layer 31 and the rollers 32, so that the airbag body 3 can slide along the multiple rollers 32, and the airbag body 3 can be easily rotated, thereby preventing the airbag body 3 from being damaged due to excessive squeezing or friction. In addition, the shear force can also be reduced. The multiple rollers 32 also produce a stable supporting effect, so that the areas of the two sides of the airbag body 3 that are squeezed are relatively large, and the energy generated by the squeezing is dispersed more evenly.

[0052] When the ship and the dock are in an oblique extrusion state, the arc frame 21 slides in the arc clamp 13, changing the orientation of the airbag body 3 so that the airbag body 3 can face different directions, keeping the airbag body 3 vertically hitting the dock, minimizing the shear force, avoiding damage to the airbag body 3, and making the airbag body 3 relatively evenly extruded, thereby ensuring its service life and stability. In addition, when the airbag body 3 outside the arc frame 21 is extruded from the dock, the arc frame 21 will slide, and no additional force is required to make the airbag body 3 vertically extruded from the dock.

[0053] Seawater is relatively corrosive, and metal products are prone to rust. Therefore, after the airbag body 3 is squeezed and deformed, it will push the lubricating part 4, so that the two layers of arc-shaped plate layers 41 squeeze the support spring 43 and are relatively close to each other, so that the liquid outlet pipe 45 discharges the lubricating liquid into the arc-shaped clamping opening 13. When the arc frame 21 moves, the lubricating liquid is coated on the inner wall of the arc-shaped clamping opening 13 and the outer side of the arc frame 21 to avoid rust and affect the movement. In addition, when there is no squeezing, the lubricating part 4 is restored, and the arc-shaped plate layers 41 on both sides are pushed under the action of the support spring 43, so that the liquid inlet pipe 44 can be filled with liquid. When the ship is docked, under the action of waves or sea breeze, the airbag body 3 can be squeezed by the dock at intervals, so as to achieve continuous lubrication.
