The cover 114 is spaced apart from the outer circumferential surface of the conductor 112 by a predetermined distance in order to prevent the conductor line 116 formed on the inner surface of the cover 114 from contacting the conductor 112. [ to be. The cover 114 may be formed using a thin vinyl or plastic injection molded article having a predetermined rigidity. The cover 114 is made of an insulator material. The lower side of the cover 114, that is, the side facing the sea surface is open. Thus, seawater flows into the cover 114 through the opened lower side.

A plurality of conductor lines 116 are formed on the inner surface of the cover 114 at regular intervals. The conductor line 116 is energized with the conductor 112 through the seawater flowing between the cover 114 and the conductor 112. For example, the conductor line 116 and the conductor 112 located at the lower side of the height of the sea water introduced into the cover 114, that is, the waterline, are energized. When the ship 10 tilts to the left, the conductor 112 of the sensing unit 110 installed on the left side of the ship 10 and the conductor 112 of the sensing unit 110 installed on the right side of the conductor line 116, And the conductor line 116 are more energized.

At this time, if the ship 10 is tilted at a predetermined angle or more and is continued for a predetermined time, the driving unit 120 is operated.

The driver 120 of the opening and closing port 12 in the tilted direction of the ship 10 can detect the opening and closing of the door 12 through the circuit provided in the driving unit 120 during the operation of the driving unit 120, So that the opening / closing port 12 is closed.

In addition, when the door 12 is closed, a danger alarm is generated and the passenger and the crew are prompted to escape quickly. That is, it is possible to suggest a direction in which the door 12 is closed and the risk is known to evacuate, thereby leading to the escape of the passenger and the crew.

In addition, a structural signal is sent together with the blocking of the door 12 and the occurrence of a critical alarm through the control unit.

By monitoring the equilibrium state of the ship 10 in real time through the sensing unit 110 as described above, the opening / closing port 12 formed in the tilted direction can be quickly closed even if the ship 10 is suddenly tilted due to an unexpected accident So that the sinking time of the ship 10 is delayed. Accordingly, it is possible to secure the time for the crew and the passenger to escape, thereby minimizing the damage to the person.
