Next, one or more tables 130 are installed in the mess room, and the center area is supported by a support 131 fixed upright from the floor of the mess room to provide a dining environment for sailors. Here, the support 131 is coupled to the center of gravity of the bottom surface of the table 130 .

On the other hand, although not shown, an anti-slip pad is attached to the top surface of the table 130, an anti-slip coating liquid is coated, or a groove corresponding to the shape of the bottom of tableware is formed, resulting in slight vibration or back and forth left and right. Even when tilted, you can prevent tableware from slipping and leaning in one direction.

Next, the two-axis gimbal 140 is a configuration that maintains the horizontality of the mess room table 130 constant regardless of the motion of the roll and pitch of the hull according to various sea conditions, and as shown in FIG. 2, the support It is disposed between the 131 and the table 130 to maintain the horizontality of the table 130 by adjusting the roll direction rotation and the pitch direction rotation of the table 130 according to the ship attitude.

Next, the control unit 150 generates a control signal for maintaining the horizontality of the table 130 according to the ship attitude information received from the console 120 to operate the first motor 142 and the second motor 142 of the two-axis gimbal 140. The rotation drive of the motor 144 is respectively controlled.

Meanwhile, referring to FIG. 3 , a seismic isolation module 160 absorbing vibration may be interposed between the third flange 145 and the lower surface of the table 130 . That is, as mentioned above, the third flange 145 and the table 130 may be directly fixed to each other, but the seismic isolation module 160 may be interposed therebetween to absorb minute vibrations.

Specifically, the seismic isolation module 160 is formed to face the first plate 161 coupled to the upper end of the third flange 145 and the first plate 161 so as to be spaced apart in the vertical direction and to the lower surface of the table 130. It consists of a second plate 162 fixedly coupled to and a vibration absorbing pad 163 coupled between each corner of the first plate 161 and the second plate 162 to absorb vibration, and the surge of the hull ( By absorbing minute vibrations in three axial directions according to surge, sway, and heave, shaking of the table 130 may be minimized.

Here, the vibration absorbing pad 163 may be made of a highly elastic material and formed in a cylindrical shape, but may be replaced with an elastic body such as a highly elastic spring.

In addition, as shown in FIG. 1, the control unit 150 may integrally control the horizontality of the entire table 130 in the mess room, but as shown in FIG. 5, one side of the bottom of the table 130 is the hull. A gyro sensor 171 for self-sensing the horizontality of the individual table 130 according to the trim or list is formed, and the control unit 172 is formed for each table 130 and receives the table 130 from the gyro sensor 171. ) by generating a control signal to maintain the horizontality of the table 130 according to the attitude information on the horizontality of the table 130 to individually control the corresponding two-axis gimbals 140 of the table 130, so that the control unit 150 of a single configuration It is also possible to avoid leveling failure of the entire table 130 due to risk according to the integrated control by ), for example, an error of the controller 150 itself or a control signal transmission error to the two-axis gimbal 140.

Here, in addition to the gyro sensor 171, an acceleration sensor for detecting rotation in the roll and pitch directions may be used, and a load sensor for detecting the arrangement of tableware is formed on the table 130, and a weight exceeding a threshold value is detected. In this case, power consumption may be reduced by rotationally driving the two-axis gimbal 140 .

Therefore, by using the above-mentioned measuring room table leveling system for ships, regardless of sea conditions such as bad weather, a two-axis gimbal is used to maintain the horizontality of the measuring room table at a constant level to provide a comfortable dining environment for sailors. , By absorbing minute vibrations in the three-axis direction, it is possible to minimize shaking of the table 130.
