In addition, as a position where the support member 6 is installed, a place that can be reached immediately when the door of the bridge is opened and the exposure deck is reached is preferable.

  As shown in FIG. 1, from a voyage information sensor group 7 such as a physical sensor for measuring a ship position, a ship speed, etc. provided on the ship side and a conversation recording microphone on a bridge, a controller 8 and a wireless LAN transmission in a data transmission apparatus 10 are provided. The navigation information transmitted through the side device (wireless transmission device) 9 is received by the wireless LAN reception side device (wireless reception device) 11 mounted inside the buoy structure 1, and further the controller 3 Is recorded on the recorder 2 as a storage medium.

  In addition, the buoy structure 1 is provided with a satellite emergency position indicating radio sign 12 as a wireless distress signal transmission device for automatically transmitting a distress signal when the structure 1 is floating on the sea surface. Yes.

The power supply required in the buoy structure 1 is opposed to the buoy structure 1 with a minute gap (about 1 mm) so as not to hinder the buoy structure 1 from leaving in the event of a ship's distress. This is performed between the magnetic field type power receiving unit 4 on the buoy structure side capable of transmitting power and the magnetic field type power feeding unit 13 on the hull side, and an inboard power source 14 is connected to the power feeding unit 13.
The controller 3 constantly monitors the supplied power via the A / D converter 15 and automatically stops the information recording function and terminates the recorded information accurately when the power supply is stopped. The procedure to do is executed.

  As shown in FIG. 2, the release mechanism of the buoy structure 1 is such that the buoy structure 1 swings and attaches while supporting the upper end walls of the grooves 1a and 1a formed on both sides of the buoy structure 1, respectively. It is configured by providing a pair of first horizontal support shafts 16, 16 on the same horizontal line that allow upward separation in the water, and these first horizontal support shafts 16, 16 are inward from the ring member 17. Projected to.

The ring member 17 is swingably supported by the support member 6 via a pair of second horizontal support shafts 18, 18 in the horizontal direction orthogonal to the first horizontal support shafts 16, 16. The buoy structure 1 is supported by the support member 6 on the ship in a horizontal state through a gimbal mechanism including the first horizontal support shaft 16, the ring member 17 and the second horizontal support shaft 18 regardless of the movement of the hull. ing.
