[0057] The first outer panel 214 may connect the first outer edge and the second outer edge to each other and may have an arc-shaped cross section to form an outer surface that faces the inner perimeter of the exterior barrel 202.

[0058] To provide a structure for coupling with the exterior barrel 202 while at the same time increasing the overall structural strength, the interior sections 210 may further include reinforcing coupler grooves 215 that are formed parallel to one another, recessed in the first outer panels 214, such that annularly shaped recesses are formed parallel to one another along the outer perimeter of the interior barrel 201.

[0059] Here, the reinforcing coupler grooves 215 may mate with the reinforcing coupler ribs 225 described later on, which may be formed in a protruding manner along the inner perimeter of the exterior barrel 202.

[0060] On the other hand, an exterior section 220 can include a second upper panel 221, a second lower panel 222, a second inner panel 223, and a second outer panel 224.

[0061] The second upper panel 221 may be formed in an arc-like shape, with a third inner edge that faces the outer perimeter of the interior barrel 201 and a third outer edge that is parallel to the third inner edge and forms the outer edge of the exterior barrel 202.

[0062] The second lower panel 222 may be disposed under the second upper panel 221 and may be formed in an arc-like shape, with a fourth inner edge that faces the outer perimeter of the interior barrel 201 and a fourth outer edge that is parallel to the fourth inner edge and forms the outer edge of the exterior barrel 202.

[0063] The second inner panel 223 may connect the third inner edge and the fourth inner edge to each other and may have an arc-shaped cross section to form an inner surface that faces the outer perimeter of the interior barrel 201.

[0074] Here, the elevator pole 310 can serve to adjust the height of the lantern 320 with respect to the upper surface of the maintenance chamber 340 during a typhoon or stormy weather, so as to thereby prevent the buoy, including the lantern 320, from becoming lost or damaged.

[0075] The elevator pole 310 can also serve to allow easy access to the lantern 320, when a technician has to inspect, replace, or fix the lantern 320, and thus can prevent accidents involving falls from the height of the lantern 320.

[0076] The lantern 320 can be provided in a hybrid type suitable for various usages, such as for 3 nautical miles, 5 nautical miles, 7 nautical miles, 9 nautical miles, etc.

[0077] Here, a hybrid type refers to a structure that can be operated with electrical power produced by solar power generation using the solar panel module 341 described later on or by wind power generation using a wind power housing 370, etc.

[0078] The gear assembly 330 can include a lifting pinion 331 and a support shaft 332, where the lifting pinion 331 may rotate in engagement with the lifting rack gear 311 and may be enclosed within the maintenance chamber 340, and the support shaft 332 may support the forward and reverse rotation of the lifting pinion 331 and may be enclosed within the maintenance chamber 340.

[0079] Also, the gear assembly 330 can include a transmission worm wheel 333 and a transmission worm 334. The transmission worm wheel 333 may be coupled to the support shaft 332 to undergo forward and reverse rotation together with the support shaft 332 and the lifting pinion 331 and may be enclosed within the maintenance chamber 340. The transmission worm 334 may include a worm shaft 335 to engage the transmission worm wheel 333 and undergo forward and reverse rotation and may be enclosed within the maintenance chamber 340.

[0080] Also, the gear assembly 330 can include a drive motor 336, which may be coupled to an end of the worm shaft 335 to transfer a driving force to the transmission worm 334.

[0081] Also, the third unit 300 may preferably further include a solar panel module 341, which may be provided on one side of the maintenance chamber 340 and may include a multiple number of solar power cells that transfer power to the drive motor 336 and the lantern 320.

[0082] In addition, the third unit 300 may preferably further include a lifting crank lever 337, which may be selectively connected to and disconnected from the worm shaft 335 and which may allow the worm shaft 335 to undergo forward or reverse rotation by manual operation in emergency situations such as where the drive motor 336 is broken or is unable to provide the power necessary for raising the lantern 320.

[0083] Referring to FIG. 4, the third unit 300 can also further include weather observation equipment 350, which may be disposed at an upper side of the maintenance chamber 340 to collect meteorological data in the vicinity of the buoy assembly in real time.

[0084] The third unit 300 can also further include a battery 360, which may be encased in one of the multiple interior sections 210 and may store the electrical energy produced by the solar panel module 341 that is provided on one side of the maintenance chamber 340 to transfer power to the drive motor 336 and the lantern 320.

[0085] Also, the third unit 300 can further include a wind turbine (not shown), which may be mounted on one side of the maintenance chamber 340 and electrically connected with the battery 360 and which may be rotated by the wind around the maintenance chamber 340 to produce electrical power.

[0086] In addition, the third unit 300 can also further include a wind power housing 370, which may be connected with the wind turbine, and which may include a multiple number of blades 371 that are disposed radially for rotating with the wind.

[0087] From the above, it should be appreciated that the present invention.

[0088] As set forth above, it can be seen that the basic technical spirit of the present invention is to provide a buoy assembly having a carbon fiber body that not only allows a convenient way of inspecting the lantern but also provides a lighter weight and an increased structural strength.

[0089] Within the scope of the technical spirit of the invention, a person having ordinary skill in the art can apply the first unit 100 and the third unit 300 to the lower body 230 of a standard buoy manufactured from steel (SS400) as specified by the Ministry of Oceans and Fisheries, as illustrated in FIG. 5, instead of applying the first unit 100 and third unit 300 to the second unit 200 composed of an interior barrel 201 and exterior barrel 202 as illustrated in FIGS. 1 to 4. Thus, an embodiment of the invention can provide greater utility by way of application to a buoy of standard specifications and allows for numerous variations and adaptations.
