Technical Field
[0001] The utility model relates to the technical field of fenders, in particular to a high-energy-absorbing and anti-collision rubber fender. Background Art
[0002] Fenders are devices used to protect the sides of ships from collision and wear. Fenders are often used in areas such as docks, shipyards or ports. Their main purpose is to protect the contact between ships and docks to reduce damage caused by collisions and wear on ship structures. Existing rubber fenders are generally strong enough, but because the material structure designs of each rubber fender are different, although a single high-strength rubber fender can play the role of a fender, its impact force will be greatly returned to the ship, which may seriously cause deformation of the ship. At present, most rubber fenders are integrated structures, and they are generally replaced as a whole when damaged, resulting in high daily maintenance costs. Therefore, the present invention proposes a high-energy absorption and anti-collision rubber fender to solve the problems mentioned in the above background technology. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0020] Reference Figure 1-4A high energy absorption and anti-collision rubber fender comprises a fender body 1, the outer portion of the fender body 1 is an anti-wear layer, the middle layer is an energy absorption layer, and the inner layer is a high-strength layer, the anti-wear layer is made of a high-performance plastic material polyurethane, the middle layer is made of a thermoplastic elastomer, and the high-strength layer is made of an ethylene-propylene synthetic rubber material. Polyurethane is a high-performance plastic material with excellent wear resistance. It has high strength, excellent weather resistance and crack propagation resistance, and is suitable for applications requiring high wear resistance. TPV (thermoplastic elastomer) has good energy absorption performance. It can deform and absorb impact energy when subjected to force, thereby protecting the structure from damage. EPDM (ethylene-propylene rubber) is a synthetic rubber with excellent heat resistance and weather resistance. It performs well in outdoor environments and has high resistance to erosion by ultraviolet rays, oxygen and other chemicals.
[0021] Furthermore, referring to Figure 4 A limited push portion 10 is arranged at the rear side of the fender main body 1, and a buffer portion 2 is arranged at the rear side of the limited push portion 10. When the fender main body 1 is impacted by force, it moves backward, and the limited push portion 10 expands to both sides and squeezes the corresponding buffer portion 2 on the inner side to unload a part of the force. A steel pad portion 4 is arranged at the rear side of the buffer portion 2. A plurality of resistance portions 9 are evenly arranged at the center of the limited push portion 10. The resistance portions 9 are fixed to the rear side of the fender main body 1, and the resistance portions 9 penetrate the rear side buffer portion 2 and correspond to the rear side steel pad portion 4. When the fender main body 1 moves backward for a distance, the resistance portion 9 contacts the bow-shaped elastic steel pad portion 4, which can absorb another part of the impact force, thereby enabling the fender to play a better energy absorption and force unloading role;
[0022] Furthermore, referring to Figure 2-4 A mounting seat 3 is provided on the rear side of the steel pad 4, a buckle cover 5 is provided on the upper front side of the mounting seat 3, a limiting seat 6 located on the upper side of the buffer part 2 is fixed on the lower side of the buckle cover 5, the limiting seat 6 slides up and down on the front side of the mounting seat 3, and a plurality of springs 7 are provided between the upper side of the limiting seat 6 and the mounting seat 3, a plurality of corresponding card grooves 11 are provided on the lower side of the limiting seat 6 and the lower front side of the mounting seat 3, and a plurality of limiting buckle blocks 8 corresponding to the card grooves 11 are provided on the upper side of the buffer part 2, and a plurality of springs 7 on the upper side of the limiting seat 6, when it is necessary to remove the rear side structure of the fender main body 1, the limiting seat 6 connected on the lower side is lifted upward by the buckle cover 5, so that the limiting buckle blocks 8 on both sides of the buffer part 2 are convenient to be separated from the corresponding card grooves 11, and then the fender main body and its connecting parts are loaded and unloaded.
