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.

First claim

The invention claimed is:

1. An electromagnetic marine fender, comprising:
a) a rubber fender;
b) two electromagnet groups, each electromagnet group comprising at least one electromagnet; each electromagnet comprising: an electromagnet core, an electromagnet coil, an electromagnet steel shell, and a rubber coating covering the electromagnet steel shell;
c) tensile steel ropes;
d) an electric cable; and
e) a waterproof power socket;

wherein
the electromagnet coils of the electromagnets of the two electromagnet groups 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 comprising the electromagnet core, the electromagnet coil, the electromagnet steel shell, and the rubber coating covering the electromagnet steel shell from the center outward; and
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.

2. The electromagnetic marine fender of claim 1 , wherein the rubber fender comprises a pneumatic valve and is made of a rubber composite material.

3. The electromagnetic marine fender of claim 1 , wherein when the electromagnet group is electrified, the electromagnets have the same pole directions, the electromagnetic marine fender operates as a combined electromagnet providing a magnetic force to attract steel plates of both sides of two ships, and the two sides of the fender function as an N pole and an S pole of the combined electromagnet, respectively.
