Description

Technical Field

[0001] This utility model relates to the technical field of fenders, specifically a lightweight, integral fender. Background Technology

[0002] As a key anti-collision device that absorbs impact energy when a ship is berthing, the performance of fenders directly affects the safety of dock facilities and the ship's hull.

[0003] Traditional fenders are mostly made of steel or rubber, which have significant drawbacks: steel fenders are heavy, increasing the load on the dock and are inconvenient to install. They are also prone to corrosion from seawater over a long period of time, resulting in high maintenance costs. Rubber fenders, although elastic, are prone to aging and cracking under ultraviolet radiation and marine organisms. Furthermore, they lack an effective stress-dispersing structure and are prone to permanent deformation or tearing under long-term localized pressure conditions. Utility Model Content

[0006] Preferably, the pressure-distributing component includes an airbag block, which is located on the inner top side of the fender body. A support plate is provided at the bottom of the airbag block, and connecting pipes are provided through the support plate on both sides of the bottom of the airbag block.

[0007] Preferably, one end of the connecting pipe passes through an arc-shaped airbag along one side of the fender body, and the arc-shaped airbag is adhered to a corner of one side of the fender body. The connecting pipe and the reinforcing mesh have independent routes.

[0008] Preferably, the ends of both the transverse and longitudinal ribs are provided with rubber-coated balls.

[0009] Preferably, the outer surface of the continuous shell is provided with an anti-corrosion coating, which is a polyurea elastomer structure.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model adopts a long fiber reinforced thermoplastic composite structure, which has higher strength than steel and significantly reduces its own weight, greatly reducing the load on the dock. At the same time, it is easy to transport and install. The internal crisscross reinforcing mesh design effectively disperses impact loads. The longitudinal ribs prevent permanent crushing, and the transverse ribs convert point impacts into circumferential distributed loads. Combined with the rubber-coated ball to absorb the end stress wave, it significantly improves the impact resistance.

[0014] 2. The pressure-sharing component of this utility model achieves dynamic load rebalancing through high-pressure inert gas. During vertical impact, the pressure is evenly distributed to avoid unilateral overload, and during tilted impact, it responds quickly to achieve dynamic balance, effectively solving the problem of permanent deformation caused by local pressure.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3 This utility model provides a technical solution: a lightweight integral fender, including a fender body 1, which is integrally injection molded from a long fiber reinforced thermoplastic composite structure. The long fiber reinforced thermoplastic composite structure includes a matrix polypropylene structure and a reinforcing glass fiber structure. The polypropylene matrix has a low density, and the strength after glass fiber reinforcement is higher than that of steel, and the self-weight is reduced, which greatly reduces the load on the dock.

[0021] The fender body 1 is internally reinforced with a crisscrossing mesh of reinforcing ribs 2. The exterior of the fender body 1 is a continuous shell 3. The reinforcing mesh 2 includes transverse ribs 21 and longitudinal ribs 22. The longitudinal ribs 22 are evenly distributed along the fender axis, while the transverse ribs 21 are radially distributed with the fender's central axis as the center. The longitudinal ribs 22 resist longitudinal compression deformation, preventing the permanent crushing commonly seen in rubber fenders. The transverse ribs 21 disperse and transmit local impact forces radially, reducing cracking caused by stress concentration.

[0022] Both the transverse stiffeners 21 and the longitudinal stiffeners 22 are equipped with rubber-coated balls 23 at their tails. The rubber-coated balls 23 have elastic rubber balls embedded at the tails of the stiffeners to absorb stress waves at the ends of the stiffeners. When the ship is hit, the radial reinforcing mesh 2 converts the point impact force into a circumferentially distributed load. Combined with the buffering effect of the rubber-coated balls 23, this helps to solve the problem of permanent deformation or tearing that is prone to occur under long-term local pressure conditions.

[0023] A pressure-distributing assembly is integrally mounted on the fender body 1. This assembly is used to distribute pressure on both sides of the fender body 1 when it is under pressure. The pressure-distributing assembly includes an airbag block 5, which contains high-pressure inert gas. The airbag block 5 is located on the top side inside the fender body 1. A support plate 6 is bonded to the bottom of the airbag block 5. Connecting pipes 7 pass through the support plate 6 on both sides of the bottom of the airbag block 5. One end of the connecting pipe 7 passes through one side of the fender body 1 and connects to an arc-shaped airbag 8. The arc-shaped airbag 8 is bonded to one corner of the fender body 1. The connecting pipe 7 and the reinforcing mesh 2 have independent routes.

[0024] In a vertical impact, the airbag block 5 is compressed and the gas is evenly distributed to the two circular airbags 8 through the connecting pipe 7 to avoid unilateral overload. In an inclined impact, the ship first contacts the top side of the fender body 1. Under vibration, the airbag block 5 is compressed and the gas is evenly distributed to the two circular airbags 8 through the connecting pipe 7 to achieve dynamic load rebalancing.

[0025] The outer surface of the continuous shell 3 is provided with an anti-corrosion coating 4, which is a polyurea elastomer structure. The polyurea elastomer coating 4 is sprayed on the surface of the continuous shell 3 to form a flexible armor layer to resist ultraviolet aging, marine organism attachment and mechanical wear. The fender body 1 has mounting holes 11 at both ends. The mounting holes 11 are integrally formed with the fender body 1 to avoid stress concentration and corrosion failure caused by traditional welded mounting seats.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
