The horizontal holding means 33 includes a gimbal structure The gimbal has a rotating support frame that allows rotation about the longitudinal and lateral axes so that the device or equipment can be placed horizontally and vertically regardless of the fluctuation of the structure floating on the water.

A radar reflector 40 for reflecting the incident radar signal from the ship passing around and informing the ship of the presence of a light guide is provided under the light changer 30.

The weight center weight 50 is mounted on the lower portion of the buoyant body 20 and forms a center of gravity so that the light counterweight can stand upright without falling from the sea to the side.

A lower portion of the weight center weight 50 is provided with a fixing collar 51 which is connected to the anchor 3 placed on the bottom of the sea floor by a wire 1 so as not to deviate from a maritime area in which a light table is installed.

The buoyant body 20 is provided with a battery which is charged with electric power generated by the wave generator 60 and the tension generating unit 70 and the electric power of the battery to the electric facilities such as the light projector 30, And a controller for controlling them are installed, and they are embedded in the housing 10 to protect them from seawater or the like.

The wave generating unit 60 is installed on the side surface of the buoyant body 20 and generates electricity by using the horizontal movement of the wave.

Referring to FIG. 2A, the wave generating unit 60 includes:

A rotating body 61 disposed on the sea surface and rotating in accordance with the horizontal movement of the wave moving in a horizontal direction while being choked,

A shaft 63 coupled through the center of the rotating body 61 to rotate together with the rotating body 61,

A first generator 65 that generates power by rotating the shaft 63,

And a chain 67 for transmitting the rotational force of the shaft 63 to a gear 652 connected to the rotor 651 of the first generator 65 to rotate the rotor 651.

The shaft 61 has a curvature radius larger than that of the shaft 63. The shaft 63 is biased toward the larger radius of curvature of the rotating body 61, Rotate.

The first generator 65 includes a stator 653, a rotor 651 rotating inside the stator 653, a housing 655 housing the stator 653 and the rotor 651, And a rotation shaft 657 connected to the rotor 651 and protruding from the housing 655.

For reference, the stator 653 and the rotor 651 are composed of a permanent magnet and a coil, and the permanent magnet moves in the coil to generate an electromagnetic force, and the generated electromagnetic force is converted into electricity and charged in the battery.

Gears 652 and 612 are coupled to the rotating shaft 657 and the shaft 63 and two gears 652 and 612 are connected to the chain 67 so that the rotational force of the shaft 63 is transmitted to the rotating shaft 657 to rotate the rotor 651.

The tension generating unit (70) is self-powered by the movement of the light buoy (buoyant body) in the up and down direction by the wave of the swell.

More specifically, the wire 1 connecting the anchors 3 of the seabed and the fixed hooks 51 provided on the weight center weight 50 of the light is prevented by the blue light beam so that the light- It develops by the tension which it receives according to the vertical movement which moves in the up and down direction.

The tension generating unit (70)

A reciprocating rod 71 which is installed in the center of gravity 50 so as to be able to move forward and backward and to which the stationary ring 51 is coupled at an end exposed to the outside of the center of gravity 50,

The fixing ring 51 provided at the end of the reciprocating rod 71 is connected to the anchor 3 placed on the bottom of the sea floor by the wire 1.

Therefore, when the light-emitting element is vertically moved in the upward and downward directions with the light-receiving element (i.e., the buoyant body) lifted by the waving wave in a state in which the light-emitting element is away from the anchor 3 as far as the wire 1 can tolerate, When the reciprocating rod 71 is advanced (drawn out) by the weight center weight 50 due to this tension and the tension applied to the wire 1 is weakened, the return spring 71 is rotated by the return spring 73 So that it is retracted (drawn in) into the weight center weight 50.

As the reciprocating rod 71 moves forward and backward, the latch 77 also reciprocates forward and backward. As the latch gear 77 is rotated forward and backward, the meshing gear 79 rotates and the rotation of the meshing gear 79 The rotor of the second generator 75 rotates to generate electric power.

At this time, if the coupling gear 79 rotates forward and backward in accordance with forward and backward reciprocation of the latch 77, and the rotor rotates in the forward and reverse directions, a problem may occur in the power generation.

Thus, the coupling gear 79 is engaged with the rotor only in one direction so that the rotational force in which the coupling gear 79 rotates in the forward direction is transmitted to the rotor to rotate the rotor, and the coupling gear 79 is rotated in the reverse direction It may be desirable to prevent the rotating rotational force from being transmitted to the rotor so as not to rotate the rotor.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited to the specific details and various changes and modifications may be made by those skilled in the art And such variations and modifications are to be construed as falling within the scope of protection of the present invention.
