Description

Variable fender device in which ship's berth is variable according to tidal wave tidal wave {A VARIABLE TYPE FENDER APPARATUS}

The present invention relates to a ship docking fender (FENDER) to prevent the damage of the ship and the dock by preventing the collision of the ship and the dock when the ship is docked to the dock, in particular, the ship unloading raw, fuel of the steel mill When the sea level is lowered due to tidal freezing, the fixed fender is positioned higher than the hull, and the fender is changed to the berthing position according to the sea level due to the tidal intersect to effectively prevent the fender colliding on the upper part of the hull. The present invention relates to a variable fender device in which the ship's berth is variable according to the tides.

In general, in order to unload ships such as raw materials and subsidiary materials of steel mills, ships should be docked at the docks first. Since ships docked at the docks are loaded with a large amount of transport, even if docked safely at the docks In accordance with the movement of the pier can continuously collide with, to prevent such a collision between the ship and the pier to install a collision preventing fender on the pier, such a fender is shown in FIG.

That is, as shown in Figure 1, the wharf 100 is installed between the ship 110 and the wharf 100, the fender 120 made of raw rubber is installed to absorb the shock when the ship 110 is docked In addition, such a fender 120, according to the height of the sea level (L), and when the vessel 110 flows up and down during the vessel 110 unloading operation, to prevent damage to the vessel 110.

However, as shown in Figure 2, the height of the fender 120 is installed in the pier 100 is constant in the pier 100, the difference between the tide is very high, the height difference of the sea level (L) is quite severe, especially a large amount of Since the ship 110 in the state of shipment is lower than the sea level, in case of low tide, the fender 120 installed at a predetermined position in the state where the sea level is considerably lowered is the upper side of the hull 110a of the ship 110. If the high sea level (L) becomes high while going to the side, the ship 110 causes a large accident that the ship is overturned between the fender 120 and the sea level (L).

Therefore, in order to solve the above problems, if the sea level (L) is severely different only between tides, for the safety of the vessel 110, since the hook line and other additional work of the vessel 110 is necessary, the vessel ( Not only the unloading operation itself of 110) is delayed, but there is a risk that a worker's safety accident may occur during the operation, and marine pollution due to oil leakage occurs when the ship 110 is overturned by the fender 120. There were problems.

Of course, in the case of medium and small vessels rather than super-large vessels, rollover accidents are more likely to occur. Therefore, when a variable fender is installed in a dock where the difference between tides is severe, the position is variable according to the height of the sea level. It would be desirable to prevent the ship's rollover from occurring.

The present invention has been made in order to improve the various conventional problems as described above, the purpose of which is to change the fender to prevent the damage between the ship and the pier at the dock dock of the ship automatically depending on the height of the sea level by tidal tide By providing the installation, it is to provide a variable fender device in which the ship's berth is variable according to the tidal wave difference which effectively prevents the ship from being overwhelmed by the fender by making the ship's pier berthing more stable.
