Abstract
The invention discloses an LNG wharf breasting dolphin anti-collision device, and belongs to the technical field of wharf ship berthing safety facilities. The anti-collision device comprises shore end boxes and ship end boxes. The shore end boxes are embedded in movable tables. The shore end boxes transversely move along a wharf through motor driving, and motors and shore end electromagnets in the shore end boxes are electrically connected with anti-collision device control tables. Movable table wheels are embedded in longitudinal sliding ways, and telescopic cables drive the movable tables to move up and down. Ship end electromagnets are arranged on one sides of the ship end boxes, and externally-connected wires above the ship end boxes are electrically connected with the ship end electromagnets. Each ship end box is provided with two semicircular rings, and manually-used semicircular rings are arranged on the side faces of the ship end boxes. According to the anti-collision device, the mutual repelling force of the same poles of the magnets is reasonably utilized, force generated through mutual repelling of the ship end permanent magnets on the ship end boxes and the electromagnets on the shore end boxes to neutralize the collision force generated through the transverse movement of an LNG ship. The collision force of the LNG ship to a wharf breasting dolphin is reduced, the ship body surface is protected, and the safety of the LNG ship during berthing is improved.
