Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a retractable paddle device for receiving a marine supply item of a ship,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a retractable pad eye device for supplying marine supplies to a ship, and more particularly, to a retractable pad eye device for marine supply of marine supplies, To a retractable pad eye apparatus for supplying and receiving supply items.

In general, a naval vessel will return to the port when it is needed to supply fuel or supplies while performing operations on the sea, and will supply the necessary supplies and return to the sea again.

However, returning to the harbor to receive supplies in the event of an imminent operation took a lot of time and consumed more fuel.

This interferes with the operation and disables the operation for a long time.

Therefore, it is considered as an important concept in the operation of the Navy that replenishment of supply items directly from supply lines at sea is called RAS (Replenishment at sea) or FAS (Fueling at sea).

Therefore, in order to solve this problem, there has been developed and disclosed a device capable of supplying supplies from the sea to the sea.

1 is a cross-sectional view showing the prior art.

The sliding pad eye according to the prior art shown includes a first member having a hollow cylindrical shape, a hatch located at an end of the first member and opening and closing the upper end of the first member, A second member having a hollow cylindrical shape and being upwardly moved and projecting from an end of the first member, a ball screw incorporated in the first member and being moved upward by rotation of the motor, A guide rail which is embedded in the first member, extends through the first member and extends to the second member and is embedded in the second member, and a guide rail which moves along the guide rail and is moved upward and downward by the rotation of the ball screw And allowing the naval vessels to supply supplies or fuel while the naval vessels remain in the sea without returning to the port for supply or fuel supply There is an advantage that long operation can be performed.

However, since the post projecting from the first member has only one second member, the length of the second member must be longer to secure the protruded height. If the length of the second member is long, the length of the first member for accommodating the second member must also be long. In this case, since the first member must be installed in a state of being embedded in the deck, There is a problem that needs to grow.

Therefore, since the depth of the deck is generally limited, it is impossible to extend the first member as necessary to secure the length of the second member.

The operation of fixing the second member by using the stopper and the support pipes to fix the second member in a protruded state has a disadvantage of delaying the operation because it is very difficult to set it correctly unless it is an expert.
