Abstract

The invention relates to a non-Newtonian fluid wharf fender device. The non-Newtonian fluid wharf fender device comprises a fender base body, a rubber bag and anti-collision rubber, wherein a non-Newtonian fluid layer is arranged in the rubber bag; two horizontal fastening plates are installed in the fender base body; spring rod rails and spring frame sets are symmetrically arranged on the upper side and the lower side of a guide spring rod; the spring rod rails are installed on the fender base body and fixedly connected with the inner sides of the fastening plates; spring rods are installed in the spring rod rails and hinged to connecting rods; the connecting rods are hinged to the rubber bag; one end of each spring frame set is fixedly connected to the fender base body, and the other end of each spring frame set is fixedly connected with a damping plate; and the outer side of each damping plate is fixedly connected with the anti-collision rubber. By the adoption of the non-Newtonian fluid wharf fender device, the damage of excessive impact force of a berthing ship to a wharf structure can be greatly reduced, and kinetic energy generated when the berthing ship collides and impacts is effectively buffered and absorbed.

Description

technical field

[0001] The invention relates to the technical field of wharf fenders, in particular to a non-Newtonian fluid wharf fender device. Background technique

[0002] During the berthing process of engineering ships, there are objective situations of berthing collisions, and fender structures are generally used to deal with external impacts. Under the collision and extrusion of berthing ships, the fender structure usually undergoes large deformation to protect the wharf structure. During the collision and impact, it must be able to buffer and absorb the kinetic energy of the berthing ship, and at the same time, the reaction force generated by extrusion deformation should be minimized. Possibly small, to avoid fatigue damage to the wharf structure caused by frequent berthing. In the prior art, only relying on rubber fenders or steel fenders is difficult to meet the actual needs, not only the buffering effect is poor, but also the energy when the ship collides with t...
