BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for indicating the capsizing / sinking position of a ship, and in particular, when it is mounted on a ship and the ship is capsizing or sinking, it detects this event and emits a signal sound to notify the ship. The present invention relates to a position indicating device for a capsized / sunk ship, which is adapted to indicate a capsizing or sinking position.

[0002]

2. Description of the Related Art At present, as a lifesaving equipment for a ship in a disaster, as shown in FIG. 3, an emergency position indicating radio beacon (EPIRB) using a polar orbit satellite 1, a radar transponder (a satellite-mounted repeater). ) Is known to use radio waves. Reference numeral 2 in FIG. 3 is radio equipment on the ground, reference numeral 3 is communication equipment on the ground, reference numeral 4 is a rescue boat, reference numeral 5
Shows the ship in distress.

[0003]

By the way, when a ship capsizes or sinks, it is difficult to confirm the position of the ship in distress with a position indicating device using radio waves such as the conventional EPIRB. There is a demand for the realization of a system that enables the position to be determined even in such a case. The present invention addresses such a demand, and when a ship is in distress (in the case of capsizing or sinking), it detects this event and emits a signal sound to indicate the distress position of the ship. It is an object of the present invention to provide a position indicating device for a capsized / sunk ship by attaching a ship to a ship to indicate the distress position of the ship.

[0004]

In order to achieve the above-mentioned object, a position indicating device for a capsized / sunk ship according to the present invention includes a seawater battery attached to the ship for detecting seawater and generating electromotive force, and a seawater battery for the seawater battery. It is characterized in that it is configured to have a squib switch operated by electromotive force and a sounding body that generates a signal sound by the operation of the squib switch.

[0005]

In the position indicating device for a capsized / sunk ship of the present invention described above, the seawater battery functions as a sensor for detecting the capsizing or sinking of the ship, and turns on the squib switch. When the squib switch is turned on, the electric circuit is closed and a signal sound is emitted from the sounding body (pinger).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is a description of the position pointing device for a capsized / sunk ship as an embodiment of the present invention, with reference to the drawings. FIGS. 1 (a) to 1 (d) are side views showing its operating state, and FIG. It is a circuit diagram.

As shown in FIG. 1 (a), in this embodiment, a position indicating device 11 is attached to the ceiling of a steering room 10a of a ship 10. The position indicating device 11 includes a seawater battery 12, a squib switch 13, a sounding body (pinger) 14, and a power supply unit 15 (see FIG. 2).
See)). A seawater battery is a type of battery that generates electromotive force when detecting seawater. The electromotive force of a single unit is about 1.2 V, and a plurality of seawater batteries are connected in series to form a seawater battery 12. And, here, such a seawater battery 12 is used as a means for detecting the capsizing or sinking of a ship.

A coil 13a of the squib switch 13 is connected to a pair of output terminals of the seawater battery 12, and a contact 13b which is operated "closed" by energizing the coil 13a is provided. Note that the squib switch 13 is a one-shot component, and is configured to maintain this state once the contact 13b is "closed". The contact 13b is connected in series in an electric circuit 16 that connects the power supply unit 15 and the sounding body 14, and the electric circuit 16 is closed by the operation of the squib switch 13 (closing operation of the contact 13b) to supply the sounding body 14 with power. The power of the section 15 is supplied. The power supply unit 15 is equipped with a normal battery 15a.

In the above structure, when an event such as capsizing or sinking of the ship 10 occurs (FIG. 1 (b)), the seawater battery 12 is submerged in the sea, which causes electromotive force in the seawater battery 12 and the squib switch 13 Throw in. When the squib switch 13 is turned on, the electric circuit 16 is closed, and the sounding body 14 emits a signal sound 17 (FIG. 1 (c)).

On the other hand, the sunken ship detection robot 18 continues to travel while searching for the signal sound 17 transmitted from the position pointing device 11 on the ship 10, and after detection, it floats and generates a detection confirmation signal 19 (FIG. 1). (d)]. Then, the detection confirmation signal 19 is received by the lifeboat, the rescue aircraft, the ground base, or the like. In this way, early detection of a distressed ship can be performed.

It is possible to search for the signal sound 17 by a plurality of sunken ship detection robots 18, and by doing so, it is possible to discover a distressed ship earlier. Also,
When the detection device for the signal sound 17 is attached to the lifeboat, the lifeboat itself can detect the distressed ship, which enables earlier rescue. It is also possible to use a normal sonar as a detection device for the signal sound 17.

[0012]

As described above in detail, according to the position-indicating device for a capsized / sunk ship of the present invention, the position of a capsized or sunk ship can be determined, and a distressed ship can be found early. Is obtained.
