1. Device for fighting forest fires, characterized in that it comprises:
- a first tank (5) containing an extinguishing liquid which is equipped with a telescopic vertical column (8) which bears at its top a rotary diffuser (9) and which is contained inside said first tank in the folded state;
a source of compressed gas (10) which is connected to said first tank (5) through obturation means (21);
and means for controlling the opening of said obturation means in the event of a fire, with the result that said compressed gas places said extinguishing liquid under pressure and the latter rises in said column whilst unfolding it, with the result that said diffuser (9) is located above the trees.

Abstract
A device having a first tank which is equipped with a telescopic vertical column which is contained in the folded state in the tank which contains a liquid and which bears a diffuser. The device includes a second reserve tank and further includes flame detectors distributed on the periphery of the tanks. When a flame is detected, an electronic central unit automatically controls pyrotechnical obturators which place bottles of compressed gas in communication with the first tank.

6. Device for fighting forest fires comprising:
-
a first tank containing an extinguishing liquid which is equipped with a telescopic vertical column which bears at its top a rotary diffuser, which column is contained inside said tank in the folded state; a source of compressed gas which is connected to said first tank via obturation means; a plurality of flame detectors which are distributed in the forest about said first tank and at a distance therefrom, said flame detectors being constituted by ambient temperature sensors associated with electronic circuits which calculate the rate of variation of the temperature and which compare this rate with a determined threshold; and a central unit which comprises a radio station which communicates with said flame detectors and which automatically opens said obturation means when one of the detectors transmits to said radio station a flame detection signal with the result that said compressed gas places said extinguishing liquid under pressure and said liquid rises in said column while unfolding it with the result that said rotary diffuser is located above the trees. - View Dependent Claims (7, 8, 9, 10)

11. Device for fighting forest fires comprising:
-
a first tank containing an extinguishing liquid which is equipped with a telescopic vertical column which bears a rotary diffuser at the top thereof, which column is contained in said tank in the folded state; a source of compressed gas which is connected to said first tank through obturation means; and a plurality of flame detectors which are distributed in the forest about said tank and at a distance therefrom and which command the opening of said obturation means in the event of a fire, with the result that said compressed gas places said extinguishing liquid under pressure and that said liquid rises in said column while unfolding it so that said rotary diffuser is located above the top level of the trees; wherein said tank comprises articulated flaps which are normally folded down above said tank and means for automatically unfolding said flaps in the event of rain in order to collect the rainwater into said tank. - View Dependent Claims (12)

-
a first tank containing an extinguishing liquid which is equipped with a telescopic vertical column which bears at its top a rotary diffuser and which is contained inside said first tank in the folded state; a source of compressed gas which is connected to said first tank through obturation means; means for controlling the opening of said obturation means in the event of a fire, with the result that said compressed gas places said extinguishing liquid under pressure and the latter rises in said column while unfolding it, with the result that said diffuser is located above the trees; a second tank which is equipped with a pump for transferring a liquid from the second tank into the first tank; and articulated flaps which are folded down above said tanks and which are automatically opened in the event of rain in order to collect the rainwater and to send it into said second tank. - View Dependent Claims (14, 15, 16, 17, 18)
