Technical Field

[0001] This utility model relates to the field of anti-collision fender technology, and in particular to a high-strength corrugated sandwich anti-collision fender of an independent pier-type anti-collision system. Background Technology

[0002] With the rapid development of the shipping industry, the number and tonnage of ships are constantly increasing, which also increases the risk of ship collisions with bridges. To protect bridge structures from damage by ship collisions, the development of collision protection facilities has become increasingly important. Independent pier-type collision protection systems, as an effective collision protection solution, have attracted much attention because they can be arranged independently of the piers, forming an effective protective barrier for them. High-strength corrugated sandwich collision fenders, as an important component of this system, have become a research hotspot due to their excellent impact resistance and energy absorption capabilities.

[0003] Existing anti-collision fenders suffer from low overall impact resistance and short overall service life. Therefore, it is particularly important to design a high-strength corrugated sandwich anti-collision fender with an independent pier-type anti-collision system to solve the above-mentioned technical problems. Utility Model Content

Therefore, a high-strength corrugated sandwich anti-collision fender of independent block-type anti-collision system is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-strength corrugated sandwich anti-collision fender of an independent pier-type anti-collision system, comprising a hull, a fender body installed on the hull by fasteners, a limiting seat fixedly connected to the inner wall of the hull, the fasteners passing through the hull and threadedly connected to the limiting seat, a buffer cylinder fixedly connected to the fender body, the end of the buffer cylinder abutting against the hull, and the cross-sectional structure of the fender body is a trapezoidal structure.

[0006] Preferably, after the fastener completes its positioning work on the hull, the end of the fastener is welded to the positioning seat, and the welding point is re-welded when the fender body needs to be disassembled.

[0007] Preferably, a buffer pad is fixedly connected to the outer wall of the fender body, the buffer pad is located at the corner of the fender body, and a reinforcing rib is fixedly connected to the corner of the inner wall of the fender body.

[0008] Preferably, a buffer spring is installed on the inner wall of the buffer cylinder.

[0009] Preferably, the fender body has a multi-layer structure design, with the outer layer being a corrosion-resistant layer and the inner layer being a steel frame material.

This, along with the buffer cylinder and buffer spring structure inside the fender body, significantly improves the impact resistance of the fender body structure. The fender body structure is installed on the hull using fasteners and a limiting seat. The ends of the fasteners are welded to the limiting seat to ensure the relative stability of the fender body on the hull. Compared to conventional fender bodies with low overall impact resistance, the technical solution adopted in this utility model greatly improves the overall impact resistance of the fender body, significantly extends the service life of the overall structure, and features a compact structure, reasonable spatial layout, and ease of installation and maintenance.

A buffer spring 401 is installed on the inner wall of the buffer cylinder 4, which forms effective support inside the buffer cylinder 4 and can effectively buffer the impact force.

[0020] In actual use, the high-strength corrugated sandwich anti-collision fender of the independent pier-type anti-collision system is installed in the limiting seat 3 through the hull 1 using fasteners 201. Fasteners 201 are threadedly connected to both the fender body 2 and the limiting seat 3. After the fasteners 201 are installed on the limiting seat 3, the ends of the fasteners 201 are welded to the limiting seat 3 to improve the relative stability between them. When the fender body 2 needs to be disassembled and maintained later, the welded ends will be welded to the limiting seat 3. The fender body 2 is melted and then disassembled. A buffer pad 5 structure is installed on the outer wall of the fender body 2. The buffer pad 5 is located at the corner of the fender body 2, providing sufficient protection for the fender body 2 structure. The fender body 2 structure is designed as a two-layer structure: an outer layer of corrosion-resistant material and an inner layer of steel frame material. The cooperation of the two layers improves the overall impact resistance of the fender body 2 structure. A buffer cylinder 4 structure is installed on the inner wall of the fender body 2, and a buffer spring 401 structure is installed inside the buffer cylinder 4. Effective support is provided on the inner side of the main body 2. The buffer cylinder 4 is made of energy-absorbing material, which can effectively buffer the impact force on the fender body 2.

By designing the fender body 2 as a multi-layer structure, combining the outer corrosion-resistant material with the inner steel frame material, and with the buffer cylinder 4 and buffer spring 401 structure inside the fender body 2, the impact resistance of the fender body 2 structure is greatly improved. The fender body 2 structure is installed on the hull 1 with the limiting seat 3 on the hull 1 through fasteners 201. The end of the fastener 201 is welded to the limiting seat 3 to ensure the relative stability of the fender body 2 fixed on the hull 1. Compared with the conventional fender body 2 with low overall impact resistance, the technical solution adopted by this utility model greatly improves the overall impact resistance of the fender body 2, greatly extends the service life of the overall structure, has a compact structure, reasonable spatial layout, and is easy for staff to install and maintain.

The outer layer of the fender body 2 is a corrosion-resistant layer, the inner layer of the fender body 2 is made of steel frame material, and the buffer cylinder 4 is made of energy-absorbing material. The cross-section of the buffer cylinder 4 is a cylindrical structure.

The cooperation of the two-layer structure improves the impact resistance of the overall structure of the fender body 2. A buffer cylinder 4 structure is installed on the inner wall of the fender body 2, and a buffer spring 401 structure is set in the buffer cylinder 4 to provide effective support on the inner side of the fender body 2.

[0024] Working principle: The fender body is installed in the limiting seat through fasteners passing through the hull. The fasteners are threaded to the fender body and the limiting seat. After the fasteners are installed on the limiting seat, the ends of the fasteners are welded to the limiting seat to improve the relative stability between the fasteners and the limiting seat. When the fender body needs to be disassembled and maintained later, the welded points are melted before disassembly. Buffer pad structures are installed on the outer wall of the fender body, and the buffer pads are located at the corners of the fender body to fully protect the fender body structure. The fender is designed with a two-layer structure: an outer layer made of corrosion-resistant material and an inner steel frame. The cooperation of the two layers improves the overall impact resistance of the fender. A buffer cylinder structure is installed on the inner wall of the fender, and a buffer spring structure is set in the buffer cylinder to provide effective support on the inner side of the fender. The buffer cylinder structure is made of energy-absorbing material, which can effectively buffer the impact force received by the fender. At the same time, the buffer spring structure is set in the inner position of the buffer cylinder to improve the ability to disperse and buffer the impact force at the buffer cylinder position.
