Description

Technical Field

[0001] The present invention relates to the technical field of energy dissipation fenders, in particular to a fixed steel-clad composite energy dissipation fender. Background Art

[0002] Fixed steel-clad composite energy-dissipating fenders are widely used as protective devices for water facilities such as docks and ports. They are designed to absorb and cushion the impact energy between ships and docks, reducing structural damage caused by collisions. Primarily composed of a steel structure and multi-layered composite materials, these fenders are designed to provide long-term, stable collision protection and minimize damage to facilities.

[0003] The prior art discloses an invention patent with application number CN104947578A, which discloses a steel-clad composite material energy dissipation fender, which is basically described as follows: comprising an outer shell, the main structure of the outer shell being a steel plate layer, the inner surface of the steel plate layer having an inner protective layer, the outer surface of the steel plate layer having an outer protective layer, the steel plate layer having a plurality of through holes, the through holes connecting the inner and outer surfaces of the steel plate layer, the inner and outer protective layers being interconnected at least at the through holes. The steel-clad composite material energy dissipation fender of the present invention uses steel plates as the main structure of the outer shell, thereby improving the rigidity of the outer shell and making it less prone to deformation; protective layers are provided on both the inner and outer surfaces of the outer shell, and the inner and outer protective layers are interconnected, making it less likely for the protective layers to detach from the steel plates, thereby ensuring the function of the protective layers and preventing the steel plates from being exposed and rusting or corroded.

[0004] In the actual implementation process, there are still some problems:

[0005] Traditional design methods mostly use pure rubber fenders, or add a layer of steel plate or other metal materials on the outer surface of the rubber to enhance rigidity. Rubber materials have good elasticity and cushioning capacity, and are suitable for energy absorption in mild impact situations. However, the energy absorption mechanism of rubber materials is relatively simple, and energy is mainly dissipated through its deformation and rebound. Under high-energy impacts, rubber cannot effectively disperse the impact energy to a larger area, which can easily cause local damage or deformation. In addition, rubber is easily affected by environmental factors such as ultraviolet rays and salt spray. Over time, it is prone to aging, embrittlement and hardening, resulting in a decrease in the cushioning capacity of the fender. The high elasticity of the rubber layer makes its rebound force greater after a collision. This may cause a secondary collision with the ship or additional impact on the dock itself. Some traditional designs use a composite structure of metal layers (such as steel plates) and rubber layers. This design uses external steel plates to enhance the impact resistance of the fender, while the internal rubber layer is mainly responsible for absorbing energy. During long-term use, the combination of steel plates and rubber layers is easily affected by environmental corrosion, ultraviolet rays and temperature changes, resulting in failure of the bonding between the layers, resulting in interlayer peeling and falling off. In addition, when a traditional fender is hit, it cannot promptly inform the management personnel of the intensity and direction of the collision or the damage to the fender. This will cause the port management to be unable to take timely measures to repair or replace it, increasing potential risks. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0032] Please refer to Figures 1 to 5 As shown, a fixed steel-clad composite energy dissipation fender of the present invention includes a bridge body 1, an energy dissipation fender body 202 is provided on the outer wall of the bridge body 1, and an anti-collision optimization mechanism 2 and a composite energy dissipation mechanism 3 are provided on the outer side and the inner side of the energy dissipation fender body 202 respectively;

[0033] The anti-collision optimization mechanism 2 includes an anti-collision side plate 208, a buffer spring 206, a trigger plate 205, and an audible and visual alarm 209. The buffer spring 206 is fixedly connected to the inner side of the anti-collision side plate 208, and the trigger plate 205 is fixedly connected to the inner side of the anti-collision side plate 208. One side of the trigger plate 205 is provided with an audible and visual alarm 209;

[0034] The composite energy dissipation mechanism 3 includes a steel cladding 301 , a carbon fiber reinforcement layer 302 , a thermoplastic polyurethane layer 303 , a high-density cross-linked foam buffer layer 304 , a rubber core layer 305 and a glass fiber reinforcement layer 306 . In the actual implementation process, the composite energy dissipation mechanism 3 is set up to achieve efficient absorption and dispersion of impact energy, thereby effectively protecting port facilities and ships from collision damage. The fender is composed of a steel cladding 301, a carbon fiber reinforced layer 302, a thermoplastic polyurethane layer 303, a high-density cross-linked foam buffer layer 304, a rubber core layer 305 and a glass fiber reinforced layer 306. Each layer of material has a unique function and works together to provide excellent energy dissipation effect. The outer surface of the steel cladding 301 is provided with an anti-corrosion ceramic coating to prevent corrosion in the marine environment; the carbon fiber reinforced layer 302 is used to disperse the initial impact load and is tightly combined with the steel cladding 301 through a high-performance epoxy resin adhesive; the thermoplastic polyurethane layer 303 further absorbs deformation energy and is connected to the carbon fiber layer by hot pressing composite; the high-density foam buffer layer is connected to the thermoplastic polyurethane layer 303 through an interface adhesive and a mechanical interlocking structure for multi-directional dispersion of impact energy; the rubber core layer 305 serves as the core energy dissipation layer and is tightly combined with the foam buffer layer through a composite calendering process to absorb and dissipates most of the impact energy; the glass fiber reinforced layer 306 improves the fender's compressive and shear resistance, preventing the energy dissipation layer from deforming or falling off during an impact. This design enables the fender to have excellent energy absorption, corrosion resistance, aging resistance, and UV resistance in long-term use, significantly improving the stability and durability of the structure, reducing maintenance costs, and being able to cope with impacts of different directions and intensities, effectively extending the service life of the fender, and providing long-term, reliable protection. When a ship hits the protective side plate, the protective side plate will effectively release the impact force and deflect. During the deflection process, the trigger plate 205 on the inside of the protective side plate will activate the sound and light alarm 209 to sound an alarm, alerting relevant personnel. For users who need to analyze the impact direction later, they can determine the source of the ship's impact based on the direction of the alarm trigger. In addition, multiple buffer springs 206 are provided on the inside of the protective side plate to further release the impact energy, effectively reducing excessive damage to the bridge body 1 and the energy dissipation fender body 202, thereby ensuring the safety and long-term stable operation of the facility.

[0035] Optionally, the energy dissipating fender body 202 is fixedly connected to the outer wall of the bridge body 1 via a locking pin 203, and a threaded sleeve 204 is rotatably connected to the inner side of the energy dissipating fender body 202. In actual implementation, the energy dissipating fender body 202 is fixedly connected to the outer wall of the bridge body 1 via the locking pin 203 to ensure that the energy dissipating fender body 202 is stable and immovable during use, and can effectively absorb and disperse energy under the action of impact force, thereby preventing excessive damage to the bridge body 1 when a ship hits the bridge body 1. The design of the locking pin 203 allows the energy dissipating fender body 202 to be firmly connected to the outer wall of the bridge body 1, but during maintenance or replacement, it can be quickly disassembled and installed by releasing the locking pin 203, thereby facilitating regular inspection and replacement, reducing maintenance time and cost.

[0036] Optionally, an adjustment rod 207 is threadedly connected to the inner wall of the threaded sleeve 204, one end of which is fixedly connected to the sound and light alarm 209. In actual implementation, the user can adjust the distance between the sound and light alarm 209 and the trigger plate 205 by rotating the adjustment rod 207, thereby precisely adjusting the alarm triggering sensitivity according to different impact forces. For example, when a ship approaches the dock and slightly impacts it, adjusting the adjustment rod 207 can ensure that the sound and light alarm 209 is activated only when a larger impact force occurs, thereby avoiding unnecessary alarms. However, when encountering a stronger impact force, appropriate adjustment of the adjustment rod 207 can ensure that the alarm is triggered in time, prompting staff to respond urgently. In this way, the impact alarm system has higher flexibility and operability, and can meet the needs of different types of ships and port facilities.

[0037] Optionally, the anti-collision side plate 208 is slidably connected to the outer side of the bridge body 1, and the anti-collision pad 201 is fixedly connected to the front of the anti-collision side plate 208. In actual implementation, the anti-collision side plate 208 is allowed to move relative to the bridge body 1 during a collision, thereby effectively absorbing and dispersing the impact force and reducing direct damage to the bridge body 1. The anti-collision pad 201 is made of high-performance elastic material with good cushioning and wear resistance. When the anti-collision pad 201 collides with a ship, it can effectively reduce the impact force caused by the collision, further protecting the bridge body 1 from damage.

[0038] Optionally, a steel cladding 301 is fixedly attached to the outer wall of the energy dissipating fender body 202, and an anti-corrosion ceramic coating is applied to the outer surface of the steel cladding 301. In actual implementation, the anti-corrosion ceramic coating provides additional protection for the steel cladding 301, preventing corrosion from corrosive substances such as seawater and salt spray. The ceramic coating has excellent corrosion resistance, wear resistance, and high temperature resistance, effectively extending the service life of the fender system in harsh marine environments.

[0039] Optionally, the carbon fiber reinforced layer 302 is positioned adjacent to the steel cladding 301, distributing the initial impact load and providing a primary structural reinforcement layer. The carbon fiber reinforced layer 302 is bonded to the steel cladding 301 via a high-performance epoxy resin adhesive. In practical implementation, the high strength and rigidity of the carbon fiber reinforced layer 302 enable it to rapidly disperse and transfer impact forces during a collision, reducing localized pressure on the steel cladding 301 and thereby effectively minimizing structural damage. This layer not only exhibits excellent tensile strength and impact resistance, but also enhances the overall structural stability of the energy dissipating fender, ensuring it remains in good working condition after multiple impacts. The high-performance epoxy resin adhesive, acting as a binder between the two layers, exhibits excellent adhesion and weather resistance, ensuring a secure connection between the carbon fiber reinforced layer 302 and the steel cladding 301, preventing delamination or shedding during long-term use or external impact. The epoxy resin adhesive's high bond strength and high-temperature resistance ensure the entire structure remains highly stable even in extreme environments, providing long-lasting collision protection.

[0040] Optionally, a thermoplastic polyurethane layer 303 is positioned inside the carbon fiber reinforced layer 302 to further absorb deformation energy. The thermoplastic polyurethane layer 303 and the carbon fiber reinforced layer 302 are joined using a hot-pressed composite method. In practice, this layer exhibits excellent elasticity, toughness, and impact resistance, effectively absorbing and buffering some of the deformation energy during an impact, converting the impact force into elastic deformation of the internal molecular structure, thereby minimizing damage to the fender itself. Due to its excellent rebound properties, the thermoplastic polyurethane layer 303 quickly returns to its original shape, ensuring that the energy-dissipating fender remains in good working condition after multiple impacts.

[0041] Optionally, a high-density cross-linked foam buffer layer 304 is disposed inside the thermoplastic polyurethane layer 303 to disperse and buffer impact energy in multiple directions. The foam buffer layer and thermoplastic polyurethane layer 303 are connected via an interfacial adhesive and a mechanical interlocking structure. In actual implementation, the high-density cross-linked foam layer exhibits excellent elasticity and lightweight properties. Upon impact, it can rapidly absorb and disperse the energy generated by the impact, thereby mitigating damage to the fender itself and the bridge structure. This foam layer effectively decomposes the impact force into a relatively uniform stress distribution and, through its dense structure, provides additional cushioning, further enhancing the fender's impact resistance and energy absorption efficiency. The interfacial adhesive, acting as a connecting medium between the two layers, provides strong bonding, ensuring a secure bond between the foam buffer layer and thermoplastic polyurethane layer 303, thereby preventing separation or delamination between the layers during impact.

[0042] Optionally, a rubber core layer 305 is located inside the foam buffer layer to absorb and dissipate most of the impact energy. The rubber core layer 305 and the foam buffer layer are tightly bonded via a composite calendering process. In practice, the rubber core layer 305 exhibits excellent elasticity and wear resistance, effectively absorbing impact energy during an impact. It also converts the impact force into heat or deformation energy through deformation of its internal structure, thereby reducing reaction force and minimizing damage to the bridge body 1 and the energy-dissipating fender body 202.

[0043] Optionally, a fiberglass reinforcement layer 306 is positioned inside the rubber core layer 305 to enhance the overall structure's compressive and shear resistance and prevent localized deformation or shedding of the energy dissipation layer. The fiberglass reinforcement layer 306 is bonded to the rubber core layer 305 via a hot-pressed adhesive. In actual implementation, fiberglass exhibits high strength, high rigidity, and excellent tensile strength, effectively enhancing the structural stability of the entire fender system. Especially in the event of a strong impact, the fiberglass reinforcement layer 306 improves the energy dissipation fender's compressive and shear resistance, prevents localized deformation of the rubber core layer 305, and maintains the system's integrity and functionality. Furthermore, the fiberglass layer enhances the overall structure's durability in multiple impacts, reducing damage from long-term use.

[0044] It should be noted that the various layers of the composite energy dissipation mechanism 3 are made of a variety of materials to ensure its excellent energy absorption, durability and impact resistance. The specific materials and performance indicators are as follows:

[0045] Steel cladding 301: Made of high-strength steel (such as Q235B or 304 stainless steel), it has good impact resistance, corrosion resistance and high temperature resistance. The tensile strength generally reaches 400-550MPa. The corrosion resistance is enhanced by anti-corrosion ceramic coating, which is suitable for marine and harsh environments.

[0046] Carbon fiber reinforced layer 302: Made of carbon fiber reinforced composite material (such as carbon fiber / epoxy resin composite material), it has extremely high tensile strength (about 2500 MPa), excellent rigidity and fatigue resistance, can disperse and transfer impact loads, and enhance the rigidity and impact resistance of the structure.

[0047] Thermoplastic polyurethane layer 303: High-performance thermoplastic polyurethane layer 303 material is selected, which has good elasticity, wear resistance and impact resistance. The hardness range is between 85A-95A, and the tensile strength reaches 30-50MPa. It can effectively absorb the deformation energy caused by impact and maintain its elastic recovery ability after deformation.

[0048] High-density cross-linked foam cushioning layer 304: Made of high-density cross-linked polyurethane foam or polyethylene foam, the density is usually 100-250kg / m 3, has high energy absorption capacity and compressive resistance, can effectively disperse and buffer impact energy, and reduce the stress on the fender and the bridge body 1.

[0049] Rubber core layer 305: Made of wear-resistant, oil-resistant, and aging-resistant natural rubber or synthetic rubber (such as chloroprene rubber, EPDM), it has excellent elasticity and cushioning capacity. The hardness range is usually 60-80 Shore A, which can effectively absorb and dissipate impact energy and reduce reaction force.

[0050] Glass fiber reinforced layer 306: Made of glass fiber reinforced composite material, the tensile strength of glass fiber reaches 2000-3000MPa, which can significantly enhance the compression and shear resistance of the overall structure, prevent local deformation or shedding of the energy dissipation layer, and ensure the overall stability of the fender.

[0051] To verify the actual performance of the fixed steel-clad composite energy-dissipating fender of the present invention, impact tests were conducted to evaluate the energy absorption and dispersion effects of each layer of material under different impact intensities. The experimental results show that each layer of material in the fender system plays an important role during the impact process, working together to effectively absorb, mitigate, and disperse the impact energy, thereby reducing damage to the bridge body and the energy-dissipating fender body. The following table details the performance indicators and experimental results of each layer under different impact conditions, providing data support for the optimization and application of the fender system.

[0052]

[0053]

[0054] Analysis of experimental results:

[0055] Steel cladding provides external protection for the fender system, effectively withstanding initial impact forces and minimizing damage to the internal structure. Under a 50kN impact force, the steel cladding demonstrated exceptional impact resistance and corrosion resistance, with no damage to the overall structure.

[0056] Carbon fiber reinforced layer: As the primary load-distributing layer, it evenly distributes impact energy and reduces stress on underlying layers. Under a 70kN impact force, the carbon fiber reinforced layer effectively reduces localized stress concentration and protects the integrity of the underlying material.

[0057] Thermoplastic polyurethane (TPU) layer: Provides additional energy absorption and cushioning, effectively absorbing deformation energy generated by impact. Even after a 100kN impact, the TPU layer quickly recovers to its original shape without permanent deformation or cracking.

[0058] High-density cross-linked foam cushioning layer: This layer plays a crucial role in energy dispersion and cushioning, effectively breaking down impact forces and reducing reactionary forces. Under a 150kN impact force, the foam cushioning layer successfully absorbed approximately 15% of the impact energy while effectively protecting the other layers from damage.

[0059] Rubber core: Serving as the energy dissipation core, it absorbs and transforms most of the impact energy, minimizing damage to the bridge itself. Under a 200kN impact, the rubber core successfully reduced the reaction force and protected the structural stability.

[0060] Glass fiber reinforcement: This significantly improves the overall structure's compressive and shear resistance, effectively preventing interlayer deformation or shedding. Under a 250kN impact, the glass fiber reinforcement successfully ensured the fender's structural integrity, preventing shedding or localized damage.
