Magnetic attracting fender

Abstract

The invention provides a magnetic attracting fender which comprises a shell, a permanent magnet attracting device, a control lever mechanism and a driving wheel. The permanent magnet attracting device is fixed on the inner wall of the shell, a first magnetic roller and a second magnetic roller are arranged at the upper end and the lower end of the permanent magnet attracting device respectively, the first end of a first control lever is connected with the first magnetic roller, the first end of a second control lever is connected with the second magnetic roller, the second end of the first control lever and the second end of the second control lever are provided with sliding grooves respectively, a protrusion is arranged at the first end of a third control lever and is mounted in the sliding groove of the first control lever and the sliding groove of the second control lever, the permanent magnet attracting device extends out of the a fixing rod, the driving wheel is mounted on the fixing rod through a shaft, the second end of the third control lever is connected with the driving wheel, a gear and the driving wheel rotate together in a coaxial mode, and the gear is wound by a control chain which extends out of the shell. The magnetic attracting fender can be easily mounted, has enough strength, and can effectively bear impact loads of various types under the level-four sea condition.

Description

technical field [0001] The invention relates to an offshore operation device, in particular to an anti-collision device for offshore operation. Background technique [0002] When the ship is berthing at sea, in order to avoid huge impact energy, a fender device that can absorb the impact energy-fender is installed between the two sides that are adjacent to each other. [0003] At present, traditional fenders and fenders at home and abroad are mostly filled with inflatable and low-density materials, etc., and play the anti-collision function by hanging or floating near the waterline of the hull. Usually, they can only protect against collisions on the water part, especially in irregular When the part collides, it is easy to slip and cause safety problems. For example, for a drop-shaped structure such as a submarine, most of its volume is underwater, or it cannot be used due to problems such as excessive floating of the hull in high sea conditions. [0004] At present, fender...

AI Technical Summary

Problems solved by technology

However, it is more difficult to fix the fender when the two ships are in the state for replenishment operation, and if it is fixed in advance, it will have a great impact on the resistance of the ship, which is not realistic
