In other words, the maritime marking facility refers to a facility that is installed to assist the vessel in determining its position and to assist in conditions such as turning, etc., and is equipped with a characteristic function by means of lighting, shape, painting, sound, .

Among these navigation marking facilities, light signals are transmitted by sending light away, and there are various types ranging from manned and non-manned, or small to large.

In particular, the lighter machine takes a method of rotating the light by emitting the light far away by the main motor. However, due to the unevenness of electric power generated by the life of the main motor, the change of ground installed in the lighthouse, and the change of the central axis, the rotation of the lighthouse stops when a load is generated during longevity rotation.

As a result, there is a risk of a safety accident of the ship in the case of stopping rotation of the lounger, so there is a disadvantage that the cost of additional expenditure is considerable when the main motor is replaced.

And it can not be said that the cause of revolving stop or malfunction of the lighter machine is not solved clearly and it can not be said that the revolving stop of the lighter machine does not revive simply by exchanging the main motor.

For example, in a large turning motion assistant device (Application No. 10-2013-0164576), a gear train is mounted on the back surface of a rotary plate of a sleeper, and a drive gear engaged with a gear train is driven by a motor After mounting on the shaft, the motor equipped with the motor shaft was mounted on the bearing housing of the main motor.

Here, the motor is provided with a motor bracket and a bracket provided with a speed adjuster for interrupting the rotation speed of the motor is mounted on the bearing housing of the main motor so as to expose the same to the outside.

However, there is a problem that if the rotation of the light emitting machine is stopped, the motor is manually moved through the hinge to engage with the gear train.

Therefore, it is time to demand new research and development of a rotation assist device for preventing the economical loss due to the damage of the main motor for the rotation of the mirror lamp.
