Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial cross-sectional view of the essential parts showing a rescue signal generator according to the present invention. Reference numeral 1 is a closed container made of synthetic resin, such as polycarbonate, which transmits radio waves and light well, and comprises an upper portion 1a and a lower portion 1b. Lower part 1
A male screw is engraved on the upper end of b and a female screw is engraved on the lower end of the upper portion 1a. A rubber packing is inserted between the two and tightened with a screw to form a sealed structure. Lower part 1
A weight 2 made of iron or the like is placed at the bottom of b, and the center of gravity G is floated on the center of gravity F.
When the container 1 enters the water, the weight 2 is automatically moved downward. Upper part 1 of container 1
The element of the solar cell 3 is attached to the outer surface of a,
It is covered with a transparent synthetic resin coating 4 such as transparent polycarbonate which transmits light well. The current from the solar cell 3 is a backflow prevention circuit 5 composed of a diode.
After that, the electricity is stored in the charger circuit 6 such as a nickel-cadmium battery. Then, it is supplied to the rescue signal generating circuit 8 via the mercury switch circuit 7. The rescue signal (f) from the rescue signal generating circuit 8 is transmitted from the transmitting antenna 9.

In the mercury switch circuit 7, the weight 2 is at the bottom and the antenna 9 is at the top as shown in FIG. When the antenna 9 is on the upper side and the antenna 9 is on the lower side, it is in a non-conductive state. Further, the antenna 9 is provided with the protruding portion 10 because it has a longer radio wave reaching distance and higher efficiency when the antenna 9 protrudes above the sea surface.

FIG. 2 is a partial cross-sectional view of an essential part showing a placing device of the rescue signal generating device of the present invention. The container 1 of the rescue signal generator is mounted on the mounting tool 11 of the rescue signal generator, which is made of polycarbonate, in the reverse of the normal operation state, that is, the weight 2 is on the upper side. At this time, when the protrusion 10 on the antenna side of the container 1 is inserted into the mounting tool 11, the guide through hole 12 is provided so that the container 1 of the rescue signal generating device can be held naturally and stably. It is provided. The depth of the recessed portion 13 is set so that the container 1 is substantially hidden, and blocking portions 14 and 14 'for blocking movement are provided at both ends so as not to move in the horizontal direction. By keeping the solar cell 3 side down in this manner, there is no fear of deterioration of the solar cell even when exposed to intense sunlight for a long period of time.

Next, using a U-shaped fitting 16 on a part 15 of the hull such as a mast, a screw 17a and a nut 17 are used.
Fix with b. Place the shield plate 18 at a suitable position so that the rescue signal generator can be freely detached when flooded.
By disposing the device, the rescue signal generator can be prevented from being exposed to intense sunlight or wind and rain for a long period of time, and the solar cell from being deteriorated.

If the vessel capsizes and the container 1 and the mounting tool 11 of the rescue signal generator are immersed in seawater, the container 1 escapes from the mounting tool 11 and begins to float in seawater, generating a rescue signal. Since the weight 2 of the device is on the lower side, the mercury switch circuit 7 becomes conductive, the rescue signal generating circuit 8 operates, and the rescue signal (f) is transmitted from the transmitting antenna 9. The strength of the output may be set so that the radio wave reaches about 150 km.

In the present invention, if necessary, the part 19 of the container 1 is made of a dissolving material 19 which is gradually violated when exposed to seawater and dissolves over a long period of time. Therefore, for example, after about 30 days, a hole is opened in the container 1 and seawater invades, and the operation of the rescue signal generation circuit 8 is stopped. By doing this, unnecessary rescue activities can be prevented.

Incidentally, since a search for a distressed ship is usually performed during the daytime, it is sufficient to transmit the signal radio wave from the rescue signal generator during the daytime. In that case, if a double-layer capacitor that is inexpensive and can be charged rapidly and has a large capacity is used as a power supply source instead of an expensive charger circuit 6 such as a nickel-cadmium battery, an extremely low-cost device can be obtained. realizable.

If the mounting rings 20 and 20 'are provided at two places above the center of gravity G of the closed container (on the side of the antenna) and the belt 21 is attached to the rings, the engine or the like may malfunction. When a person lifts the belt at the time of drifting and takes out the signal generating device from the mounting device, the switch circuit can operate to automatically generate a rescue signal.

FIG. 3 shows another embodiment. Reference numeral 22 is a horizontal position detecting means for detecting the inclination of the hull from the horizontal plane. The circular ring A has bearings 24 and 24 'fixed to a housing 23 fixed to a part of the hull, and is rotatably supported by supporting shafts a and a' (X axis). The circular ring B is rotatably supported by support shafts b and b '(Y axis) provided on the ring A and orthogonal to the support shafts a and a' (X axis) of the ring A. Further, the semicircular ring C is a support shaft b, b '(Y axis) of the ring B.
Is rotatably supported by support shafts c and c ′ provided on the ring B at a right angle. Weight 25 for semi-circular ring C
Is fixed, the semicircular ring C is always oriented vertically (downward).

A semicircular ring D is fixed to the ring B, and a through hole (not shown) is provided at the lowermost end of the ring D. A string 26 fixed to the center of the weight 25 is inserted through the through hole, and the other end of the string 26 is fixed to one end 28a of a rotatable rod 28 by a pivot 27 of FIG. ing. The other end of the rod 28 is formed with an L-shaped engagement piece 28b. The mounting plate of the rod 28 is a part of the housing 23.

The mounting tool 11 shown in FIG.
1a is formed of a flexible material made of synthetic resin, and the upper portion 11b
Is made of a rigid material and is provided with through holes 29, 29 'to the extent that the engaging piece 28b can be freely inserted.

Normally, the through holes 29, 29 'of the mounting tool 11 are engaged with the engaging piece 28b, and the rescue signal generating device is mounted on the mounting tool 11.

Now, the hull is centered on the (X-axis) and indicated by arrows P and P '.
When tilted in the direction, the ring A keeps the horizontal state,
The ring C is always oriented in the vertical direction, and the ring B is inclined in the directions of arrows P and P '. Since the semicircular ring D also tilts together with the ring B, the string 26 is pulled in the P direction by the through hole of the ring D, and one end 28a of the rod 28 in FIG.
Move in the direction. Therefore, the through holes 29, 2 of the mounting tool 11
9'is disengaged from the engaging piece 28b, and the rescue signal generating device 1 is disengaged from the mounting tool 11. Although the example in which the through holes 29 and 29 ′ are provided at both ends of the upper portion 11b of the mounting tool 11 has been described with reference to FIG. The through hole 29 may be provided only on the other side of the upper portion 11b so as to engage with the engaging piece 28b of the rod 28. At that time, if the upper portion 11b is fixed to the hull side and the open side of the upper portion 11b where the other through hole 29 is provided is arranged to be the sea side, the rescue signal generator 1 is sure to drop into the sea. You can

A semicircular ring E is also fixed to the ring A, and a through hole (not shown) is provided at the lowermost end of the ring E. A string similar to the string 26 fixed to the center of the weight 25 is inserted through the through hole, and the other end of the string is one end of a rotatable rod 28 which is pivotally supported by the shaft support 27 of FIG. 28
It is fixed to a.

Therefore, when the hull inclines about the (Y axis) in the directions of the arrows Q and Q ', the ring B keeps the horizontal state, the ring C always faces the vertical direction, and the ring A Tilt in the directions of arrows Q and Q '. Since the semicircular ring E also tilts together with the ring A, a string similar to the string 26 is pulled in the Q direction by the through hole of the ring E, and the one end 28a of the rod 28 moves in the arrow R direction in FIG. . Therefore, the through holes 29, 29 'of the mounting tool 11 are disengaged from the engaging pieces 28b. When the rescue signal generation device 1 enters the sea, the rescue circuit is in the normal operating position, so the switch circuit guides and the rescue signal (f) from the signal generation circuit 8 is transmitted from the transmission antenna 9.

[0028]

As described above, according to the present invention, since the solar battery is used as a power source, the problem that the rescue signal generating circuit does not operate due to the exhaustion of the battery, which has been encountered in the past, is completely solved no matter what kind of distress occurs. Will be resolved to. Also, when the distress signal generator and its mounting device go into the water, the distress signal generator automatically operates, or when the hull is tilted at a predetermined angle (for example, 45 degrees) or more from the horizontal plane, the distress signal generator is automatically operated. Since the distress signal generator falls off the placement device and enters the water, the distress signal generator automatically operates.
There is no need to perform any operation during an emergency evacuation.

Further, in another embodiment, a material eroded by seawater is disposed in a part of the container of the rescue signal generating device, and when the container is put into seawater and a desired number of days elapses, the container is Seawater invades inside and the rescue signal generation circuit stops.
Alternatively, the container sinks and the signal stops.

Further, in the normal state, since the solar cell disposed on the outer surface of the rescue signal generator is placed on the mounting device with the solar cell side facing downward, even when exposed to intense sunlight for a long period of time,
There is no fear that the solar cell will deteriorate.
