The position of the center of gravity of the ship has to be designed in such a way as to have a proper position from the beginning because it has a great influence on the safety and performance of the ship.

Therefore, it is necessary to numerically calculate the position of the center of gravity of the ship through complicated process with the preparation of the design plan and to check whether the center of gravity of the ship is coincident with the center of gravity of the vessel when the ship is completely dried.

Specifically, the weight and center-of-gravity position of each of the components constituting the ship and the load are calculated, and the center-of-gravity position of the ship is finally calculated based on the calculated results. And whether the calculated center of gravity position of the vessel corresponds to the position of the center of gravity of the vessel measured by the tilt test for finding the vertical and longitudinal center of gravity of the light condition of the ship.

The inclination test was carried out by moving the weight box on the deck of the ship by a certain distance to the left or right side of the ship and by using a conventional tilt measuring device as disclosed in Korean Utility Model Application No. 20-2013-0000054, This is a test to determine the center of gravity of the ship and the light weight by grasping the displacement of the suspended pendulum and the inclination to the ship center line.

Hereinafter, a conventional tilt measuring apparatus will be described with reference to the drawings.

The tester performing the tilt test is provided with such a conventional tilt measuring device 1 on the ship and after the weight box mounted on the ship is moved to the left or starboard side of the ship by a predetermined distance, (D).

However, when the conventional tilt measuring apparatus 1 is used, there is a problem that the displacement d of the weight P can not be accurately grasped.

3, the positions I1 and I2 indicated by the weights P on the ruler 20 are different from each other according to the positions M1 and M2 of the tester, Can not be accurately grasped.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings, which will be described in detail so as to enable those skilled in the art to easily carry out the present invention , And this does not mean that the technical idea and scope of the present invention are limited.

Hereinafter, an apparatus for measuring an inclination according to an embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 4 is a perspective view schematically showing an apparatus for measuring an inclination according to an embodiment of the present invention, and FIG. 5 is a view illustrating a use state of the apparatus for measuring an inclination according to an embodiment of the present invention.

Referring to FIG. 4, an inclination measuring apparatus 100 according to an embodiment of the present invention includes a tilting apparatus 100 that is suspended from a ceiling 110 fixed to a ceiling 110 of a cabin of a ship, A water tank 140 fixed to the bottom 111 of the cabin of the ship so that the weight 130 is movably received therein and a water tank 140 installed on the water tank 140 for moving the weight 130 A light source 150 for measuring displacement and a lighting device 160 for irradiating a light to the light source 150 so as to face the light source 150 with the weight 130 therebetween, have.

The water tank 140 may include first and second side walls 141 and 142, a front wall 143 and a rear wall 144, which form a front side and a rear side, respectively.

The water tank 140 may be formed of a transparent material so that the user can observe the inside of the water tank 140 from the outside of the water tank 140. Therefore, the child 150 and the illumination device 160 can be installed on the inner surface or the outer surface of the water tub 140. In addition, water (W) or oil is filled in the water tank (140), so that the weight (130) accommodated in the water tank (140) can be prevented from suddenly moving.
