Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hull protecting apparatus for a polar ship,

The present invention relates to a hull protection device for an OPT ship and a hull protection device for the hull protection device. More particularly, the present invention relates to a rotary type structure installed on a forward portion of a vessel or an ice- Ice), it is possible to secure the safety of the ship structure by moving the drift ice to the stern side quickly, and also to protect the hull of the polar ship operating on the ship which can reduce the operational resistance and to protect the hull It is about the Polarized Ship.

Generally speaking, iceberg refers to sea ice that drifts without being settled on the shore due to wind or currents.

The freezing point of sea ice is determined by the salt content, and normal sea water with a salt content of 34% freezes at about 2 ° C. Therefore, it is all year round in the polar regions where temperatures are extremely low, and only in the winter season in low latitudes.

Each ice block is divided into ice blocks with a diameter of 10m or more and ice blocks below it. The electrons are divided into small ice blocks, small ice blocks, large ice blocks, and large ice blocks in units of 200m, 1km and 10km in diameter.

The aggregate is divided into ice cubes according to density. The ice cubes are the ratio of ice floe to sea ice in the clock, and they are largely divided into drift ice, sand drift ice, wheat drift ice, and dense drift ice. In the broad sense, drift ice covers icebergs and icebergs derived from land ice, but drift ice is called drift ice.

In addition, since drift ice is subjected to the directional force according to the rotation of the earth, it is usually drifted to the right by about 20 to 40 degrees to the wind direction.

As such, the drift ice is widely distributed in the sea toward the polar regions where the temperature is relatively cooler than the equatorial region, so that the movement of the container ship or the oil tanker which must transport the cargo to such a region becomes a hindrance.

For this reason, the container ship or the oil tanker, unlike the conventional concept of the icebreaker, does not have its own icebreaking capability, but has a relatively small ice-making area and an ice-making capacity sufficient to overcome the ice- -strengthened Vessel).

Particularly, in the vicinity of the waterline of the fore and aft shell of the hull, it is necessary to introduce a device that can protect the drift line because it is the first part to collide with drifting ice floating in the sea.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing a hull protecting apparatus from a conventional drift ice disclosed in Utility Model Registration Registration No. 20-0406760. Fig.

As shown in Fig. 1, the vessel 10 is operating in an ice sea, and the drift ice 1 is floated on the sea surface before and after the vessel 10.

The drift ice 1 is moved by an alga or wind, and may seriously damage the ship 10 depending on its size and moving speed.

Therefore, in order to protect the ship 10 from such damage, the first member 11 and the second member 12 are attached to the hull where there is a risk of collision with the drift ice 1.

2 is a view showing a conventional flap disclosed in Patent Publication No. 10-2013-0127044.

As shown in FIG. 2, the conventional flap 20 is formed at a predetermined angle with the side of the ship so that the lower portion of the conventional flap 20 is rotatably coupled to the ship side on the ship side.

However, the conventional art has caused the breakage of the bow caused by the collision with the drift ice, and the existing problem that the drift ice is laminated on the hull is still not solved.
