Description

Technical Field [0001] The present invention relates to a sudden turn apparatus for ship,

[0001] The present invention relates to a quick turn device used for rapidly correcting a direction of a ship, and more particularly, to a sudden turn device installed on both left and right sides of a ship, And more particularly,

In general, ships can be broadly classified into commercial vessels, warships, fishing vessels and special operation vessels, depending on the purpose of use. Merchant ship is a vessel intended to carry passengers or cargo to gain freight income, and it is divided into cargo ship, ferry ship, and passenger ship.

In particular, when the ship is adjusted in the automatic navigation mode to provide the convenience of the crew, the collision occurs when the ship does not recognize the ship, It accounts for most of the accidents.

The automatic navigation control system of this kind of vessel allows the navigation to the desired position according to the international route agreement without the operation of the crew by automatic operation of the hydraulic key when only the coordinates of the desired area is input to the GPS. When the ship automatically sails, It is difficult to cope with the imminent situation such as collision. In case of large ships of 10,000 tons or more, it is difficult to hurry because of size and speed, which causes collision accident. Therefore, Special attention should be paid to collisions.

The operating state of the marine vessel whirling device according to one embodiment of the present invention constructed as above will be described with reference to the drawings

1 or 4, if an obstacle is found in front of the bow while the ship 2 is moving forward, the ship 2 must perform a sudden turn so as to avoid collision with the obstacle. In this case, Collision with the obstacle can be avoided by moving the ship 2 leftward or rightward or backward. In the present embodiment, the ship 2 is turned to the left.

The high pressure compressed air stored in the storage tank 3 is moved along the extension pipe 4 to move the plurality of nozzle units 102 So that the ship is struck in the direction B and stably moves without collision with the obstacle.

For reference, the direction indicated by the thin solid line indicates the direction in which the high-pressure compressed air is injected from the first to sixth switching units 110, 120, 130, 210, 220 and 230, and the directions A to D shown on the upper side of the ship 2 When the first to sixth switching units 110, 120, 130, 210, 220, and 230 are operated, the direction of the hovering is performed by the compressed air injected. When the first and fourth switching units 110 and 210 are operated, high-pressure compressed air is injected to both the left and right sides of the stern rear side of the ship 2, so that the ship 2 can quickly move forward .

In addition, when the sixth switching unit 230 is operated, compressed air is injected perpendicularly at the right side of the ship, so that the ship is turned rightward in the direction A of the bow,

An operation state of a marine vessel whirlpool device according to another embodiment of the present invention will be described with reference to the drawings.

2 or 5, when the ship 2 moves forward, when the cargo ship approaches from the right rear, the ship 2 performs a quick turn so as to avoid collision with the cargo ship. In this case, If the distance between the cargo ship and the cargo ship is short and it is difficult to make a right turn, the ship 2 is forwardly moved to the forward direction. The first and second driving units 500 and 600 are operated so that the first and second direction switching units 300 and 400 are moved toward the rear of the ship.

The first and second direction switching units 300 and 400 are quickly rotated to the rear of the stern of the ship 2 by the rotational force transmitted to the first and second gear units 304 and 404 around the first and second rotational shafts 302 and 402, Since the high pressure compressed air stored in the storage tanks 10 and 20 is sprayed in the direction of the arrow, the ship 2 is rapidly moved toward the C direction, so that a direct collision with the cargo ship can be avoided, Or collision with the cargo ship can be prevented.
