Abstract

Disclosed, as a device for correcting the horizontality of the small ship according to the present invention, is a device for controlling the horizontality of a small ship by using a variable mast, the device comprising: a tilt sensing unit for sensing the tilt of the small ship; a position adjustment unit formed such that at least a portion thereof can move in the horizontal direction on the deck of the small ship, and having a separate mast loaded on an upper part thereof to support the mast such that the mast is located at a predetermined height or higher; and a horizontality control unit for correcting the center of gravity of the small ship by adjusting a position of the mast through the position adjustment unit in correspondence to the tilt sensed by the tilt sensing unit.

First claim

The invention claimed is:

1. A device for correcting horizontality of a small ship by using a variable mast, the device comprising:
a tilt sensing unit for sensing a tilt of the small ship;
a position adjustment unit formed such that at least a portion thereof can move in a horizontal direction on a deck of the small ship, and having a separate mast loaded on an upper part thereof to support the mast such that the mast is located at a predetermined height or higher; and
a horizontality control unit for adjusting a position of the mast through the position adjustment unit in correspondence to the tilt sensed by the tilt sensing unit and correcting a center of gravity of the small ship.

2. The device of claim 1 , wherein the horizontality control unit compares a preset target value for the tilt of the small ship with a measurement value measured by the tilt sensing unit and move the mast in correspondence to a generated error value to correct the center of gravity of the small ship.

3. The device of claim 1 , wherein the tilt sensing unit is provided in one side of the small ship and measures trim and heel of the small ship in real time.

4. The device of claim 1 , wherein the position adjustment unit comprises:
a first sliding unit which slides in a second direction; and
a second sliding unit which is formed on an upper part of the first sliding unit and slides in a first direction perpendicular to the second direction.

5. The device of claim 4 , wherein the tilt sensing unit comprises an upper and lower portion support unit which is positioned between the second sliding unit and the mast and adjusts a vertical position of the mast.

6. The device of claim 1 , wherein the upper and lower portion support unit has a multi-joint structure in which a plurality of unit members are connected to be able to be bent along a longitudinal direction.

7. The device of claim 1 , wherein the position adjustment unit has a separate driving motor and precisely adjusts a position of the first sliding unit and the second sliding unit.
