PURPOSE:To automatically lighting up a lamp by effectively utilizing the wind power by installing a fan in the front part of a buoy body formed into an aeroplane trunk form and installing a power generator inside and a lamp in the rear part and supporting a buoy body in rotatable ways onto a buoy. CONSTITUTION:A buoy body 4 is formed to an aeroplane trunk body form having a vertical rudder 2 at the rear part. A fan 1 having a plurality of vanes is installed at the front part of the buoy body 4, and a power generator 3 is installed inside, and a waterproof cover 7 having a lamp 6 built-in is installed in the rear part. The buoy body 4 is supported in free turn 360 deg.C onto a buoy through a mast 5. In this case, the structure of the buoy body 4 is made simple by accommodating the main parts such as power generator 3 only in the front half body, and manufacture and maintenance are facilitated. Therefore, the power generator 3 is driven by utilizing the turning moment of the fan 1, and the lamp 6 is lighted up. Further, the fan 1 is always set oppositely to the direction of wind by turning the buoy body 4, and the utilization efficiency of the wind power can be improved. |
