Abstract
An electromagnetic marine fender, including: a rubber fender, two electromagnet groups, tensile steel ropes, an electric cable, and a waterproof power socket. Each electromagnet group includes at least one electromagnet. The electromagnet coils of the electromagnets have the same winding direction. The two electromagnet groups are disposed on two sides of the rubber fender, and the two electromagnet groups and the rubber fender are connected and fixed as a whole by the tensile steel ropes. The electromagnet is a combination structure including an electromagnet core, an electromagnet coil, an electromagnet steel shell, and a rubber coating covering the electromagnet steel shell from the center outward. The electromagnet coils of the electromagnets of the two electromagnet groups are connected in parallel, and the two electromagnet groups are in electric connection to the waterproof power socket via the electric cable.
