EXAMPLE An example of a tsunami warning signal transmission system using the signal projectile emitting device of the present invention will be described with reference to FIG.

When transmitting a tsunami warning signal, first place a signal projectile launcher 61 equipped with signal bullets on the ground near the coastline or on the roof of a building, and open the upper half of the trunk-like bag to the left and right. , Each firing unit 71 of the signal bullet and the firing barrel,
The upper parts of 72 and 73 are exposed. Then, the remote firing button 92 connected to the signal bullet firing device 61 by the cable 91 is pushed. The remote firing button 92 is preset with the ignition intervals of three firing units after the firing button is once pressed.

When the firing button of the remote firing button 92 is pressed, a current flows through the ignition current generator (13 in FIG. 1) of the firing barrel of the first firing unit 71, and this current causes the propulsion barrel assembly of the signal bullet to be pushed. (25 in FIG. 2) ignition charge (5 in FIG. 5)
1) ignites and the combustion of the propellant (52 in FIG. 5) begins.
Then, while discharging the combustion flame generated by the combustion of the propellant from the bottom portion, the signal bullet 11 is launched as a rocket upward from the launch tube and flies toward the sky. Then, after a lapse of a predetermined time, the fire transmitted from the delay agent (53 in FIG. 5) ignites the release agent (54 in FIG. 5), and the energy generated by the ignition causes the propelling cylinder to move into the signal bullet cylinder. The cap (Fig. 2) placed above the assembly
22), an assembly of a sound producing tube or a smoke producing tube (2 in FIG. 2).
3), and the parachute assembly (24 in FIG. 2) is the signal bullet 1
Emitted from the top of 1. The emitted sound tube or smoke tube assembly 23 flies further upward by the acceleration of the signal bullet. Then, when a predetermined time elapses, the split medicine (33 in FIG. 3 or 42 in FIG. 4) inside the assembly 23 of the sounding tube or the smoke emitting tube ignites, and the assembly 2
3 is separated or dispersed into two sound bullets 31, 32 or a large number of smoke bullets (smoke particles). From the sound bullets 31, 32 or smoke bullets thus separated or dispersed, the sounding agent or smoke generating agent separates and falls, and then fires. Due to the firing of these two sound bullets or a large number of smoke bombs, in the case of sound bullets, each of the two sounds continuously (sequentially at short intervals), and in the case of smoke bombs,
All of them smoke almost simultaneously or sequentially. As a position where this sound or smoke is generated, for example, an altitude of about 250 m above the coastline is set.

The parachute 26 of the parachute assembly emitted from the signal bullets over the coastline opens in a state of being connected to the signal bullets 11 by the string 27, whereby the parachute 26 falls to the ground or the sea surface at a gentle fall speed and is collected. .

In the case of using the signal projectile emitting device having three sets of firing units shown in FIGS. 7 to 9, the above-described signal projectile firing operation and the subsequent sounding or smoke generation in the sky are repeated three times in sequence. Be done. For example, if a signal with two consecutive sounds repeated twice and then two consecutive smokes was found above the coastline, it was notified that it was a tsunami warning signal. In this case, even a person working or playing offshore on the shoreline can easily find a signal composed of the sound and smoke, so that the tsunami warning signal can be reliably transmitted.

[0022]

EFFECTS OF THE INVENTION By using the signal projectile emitting device using the signal bullet of the present invention, when a tsunami is expected to occur, it is possible for a person working or playing offshore of the coastline to tsunami. The warning signal can be transmitted much more reliably than the conventional tsunami warning system using a method such as a speaker. The signal bullet emitting device using the signal bullet of the present invention is not only used for transmitting a tsunami warning signal, but when it is difficult to transmit information by a normal information system such as a television, a radio, or a speaker. , Or in combination with those information systems, is useful for reliable transmission of information.
