Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device for ice breaking and ship havings,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a side icebreaker, and more particularly, to a side icebreaker provided on a side of a ship to break ice flowing into a ship side.

An icebreaker operating in the polar regions is favorable for icebreaking work, and broken ice is not attached to the hull and has a bow shape that tends to fall off.

This is because the icebreaker is basically designed for icebreaking in the traveling direction, so that it is designed only considering the icebreaking ability of the forward part.

However, in the case of polar marine special vessels (drillships, FPSOs, etc.), it is necessary to carry out operations for several months in one place rather than moving continuously. At this time, when the drift ice drifts, the direction of the drift is changed by ice vaning to minimize the ice load.

However, if the hull is surrounded by drift ice, ice vaning is difficult. If the drift ice flows in the direction of the ship, the ice sheet is greatly increased in the conventional linear structure, and excessive structural reinforcement and propulsion capacity are required for structural stability and position control.

Especially, near the water line of the outer shell of the hull, it is the first part to collide with drifting ice floating on the sea, so it is necessary to introduce a device to protect it.

FIG. 1 is a sectional view showing a folded side of the side icebreaking apparatus according to an embodiment of the present invention, and FIG. 2 is a perspective view showing a folded side of the side icebreaking apparatus according to an embodiment of the present invention.

Hereinafter, a side icebreaking apparatus according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

1 and 2, a side icebreaking apparatus according to an embodiment of the present invention may include an icebreaking module 100 and a driving module 200. As shown in FIG.

The ice-breaking module 100 may include a first plate 110 and a second plate 120.

The first plate 110 may be rotatably coupled to the side of the hull 10 with the longitudinal direction of the hull 10 as a rotation axis.

The second plate 120 may be rotatably coupled to the opposite side of the first plate 110.

The second plate 120 may rotate about the first plate 110 and may be flush with or completely flush with the first plate 110.

Both the first plate 110 and the second plate 120 are spread out to the outside of the hull 10 so that the first plate 110 and the second plate 120 are flush with each other, It is possible to prevent the incoming drift ice from colliding with the ship 10.

Since the first plate 110 and the second plate 120 are folded and completely overlapped with each other, the portion protruding outside the hull 10 can be reduced.

The driving module 200 may include a first driving unit 210 and a second driving unit 220.

The first driving unit 210 may be rotatably coupled to the hull 10 on one side.

One side of the second driving unit 220 is connected to the first driving unit 210, and the other side of the second driving unit 220 is rotatably coupled to the ice-breaking module 100. The first driving part 210 or the second driving part 220 may move in the longitudinal direction of the first driving part 210 and / or the second driving part 220 with respect to the other.

In the present embodiment, the first driving unit 210 performs the piston motion with respect to the second driving unit 220. [ In this case, the first driving part 210 may be a piston, and the second driving part 220 may be a hydraulic cylinder.

According to the present embodiment, the first driving unit 210 repeatedly performs piston motion with respect to the second driving unit 220 and repeatedly folds and unfolds the ice-breaking module 100. Accordingly, the first plate 110 and the second plate 120 are repeatedly deployed by the piston movement of the driving module 200, and thus the ice-making operation can be performed.

The driving module 200 may further include a rotation restricting portion 230. One end of the rotation restricting portion 230 is hinged to the hull 10 in a rotatable manner and the other end of the rotation restricting portion 230 is rotatably hinged to the second plate 120. Accordingly, when the ice-maker module 100 is fully extended toward the outside of the hull 10, the rotation of the ice-maker module 100 can be restricted by supporting the ice-maker module 100.

Here, the rotation restricting unit 230 may be provided at a position deviated from the central portion of the ice-breaking module 100. In order to uniformly distribute the force of the driving module 200 to the entire ice-breaking module 100 and prevent the ice-breaking module 100 from being damaged due to a concentrated force when the ice-breaking module 100 is unfolded or folded, 2 driving unit 220 is coupled to the center of the ice-breaking module 100.

When the ice block module 100 is completely folded and folded, the second plate 120 may be provided with the rotation restricting part 230 receiving groove 122 for receiving the rotation restricting part 230.

Therefore, when the ice-breaking module 100 is completely folded and folded, the portion protruding outside the hull 10 can be minimized.

At this time, the rotation restricting portion receiving groove 122 may be formed at a position deviated to the right or left from the center of the second plate 120 according to the position of the rotation restricting portion 230.

When the ice-breaking module 100 is folded and completely folded, a receiving space 12 for accommodating the ice-breaking module 100 and the driving module 200 may be formed on the side of the ship.

Therefore, when the ice crating module 100 is folded when the side icebreaker according to the embodiment of the present invention is not used, the portion protruding outside the hull 10 can be minimized. Therefore, by installing the side icebreaking apparatus according to one embodiment of the present invention without damaging the aesthetics, it is possible to minimize the influence on the operation of the ship.

The side icebearing apparatus according to an embodiment of the present invention may further include a guide 300 provided on the side of the ice maker for guiding the first drive unit 210 in the upward and downward directions.

The guide 300 may be formed as a groove in the hull 10, or may be formed of a rail or the like. However, the guide 300 is not limited thereto, and may be any one as long as it can guide the first driving unit 210 in the upward and downward directions.

The ice block module 100 may further include a rotating shaft 400 passing through the first plate 110, the second plate 120, and the second driving unit 220.

The first plate 110 and the second plate 120 may be hinged to each other on the rotating shaft 400 and the second driving unit 220 may be rotatably coupled to the center of the rotating shaft 400.

Generally, the icebreaker operating in the polar regions is advantageous for icebreaking work, and broken ice is not attached to the hull 10 and has a bow shape that tends to fall off.

This is because the icebreaker is basically designed for icebreaking in the traveling direction, so that it is designed only considering the icebreaking ability of the forward part.

However, in the case of polar marine special vessels (drillships, FPSOs, etc.), it is necessary to carry out operations for several months in one place rather than moving continuously. At this time, when the drift ice drifts, the direction of the drift is changed by ice vaning to minimize the ice load.

However, when the surroundings of the ship 10 are surrounded by drift ice, ice vaning is difficult. If the drift ice flows in the direction of the ship, the ice sheet is greatly increased in the conventional linear structure, and excessive structural reinforcement and propulsion capacity are required for structural stability and position control.

Particularly, since the portion near the water line of the outer shell of the hull 10 is a portion that can collide with the drift ice floating on the sea, a device capable of protecting the drift is needed.

In order to solve this problem, the side icebreaker and the ship including the side icebreaker according to the present invention are provided with an icebreaking module 100 repeatedly deployed by the driving module 200 in order to facilitate breaking of the icebaths flowing in the side direction .

Accordingly, the side icebreaker according to the embodiment of the present invention can minimize the ice load acting on the side of the ice cubes. In addition, it is possible to prevent the drift ice from directly colliding with the ship 10, thereby protecting the ship 10.
