Description

Technical Field

[0001] This utility model relates to the technical field of ship berthing anti-collision devices, specifically an impact-resistant self-recovering port surface protection spike ball. Background Technology

[0002] Currently used fenders are mainly made of discarded tires installed on the hull and dock. Although they can play a protective role, the lack of elasticity of discarded tires means they can still damage the hull and dock in the event of a collision. While efforts are being made to develop other fender structures to address the issue of discarded tires, these designs are flawed, exhibiting poor elasticity and insufficient rebound force upon impact, resulting in poor collision protection and cushioning performance. Furthermore, they often tear during use, leading to a short service life.

[0003] CN 206654171 U discloses a secondary buffering anti-collision ball, comprising a body, at least one flange for fixing the body, and buffering tentacles evenly installed on the surface of the body. Each buffering tentacle includes an elastic rod fixed at one end to the body, and a ball seat fixed at the other end, with a rolling ball installed inside the ball seat. This invention, by setting buffering tentacles on the surface of the anti-collision ball, enables it to provide secondary buffering for the hull, protecting both the hull and the anti-collision ball, extending its service life, and reducing the cost of the hull fenders. The rolling balls in the buffer tentacles give the hull a forward-moving tendency, rather than simply passively protecting it, actively guiding it, reducing damage to the hull and improving the fender effect. The design is simple, easy to use, and can be easily modified from traditional anti-collision balls without requiring new production, making it suitable for widespread application. However, this invention requires inflation of the airbag during use. In actual use, the environment is complex, and the anti-collision ball is prone to leakage due to collisions and aging, resulting in a shorter service life. Utility Model Content
