Fire fighting machine for oil source fires - surrounds root of flame radially and smoothers it using bell movable on holder and closable at top by valve

摘要

The bell (9) has a closable valve (11,12) at its upper end, and at its lower end is open, with a substantial cylindrical lower wall part (36). To this lower part connects an upper part with a narrowing dia. (10), at the upper end of which the valve is fitted. The upper part is angled relatively to the lower part (9), and the bell is so rotatably formed in the wind direction, that the upper part can be directed at a acute angle to the wind. A device is provided for lifting and lowering the bell (9), and the dia. of the wall of the lower mouth (35) is greater than that of the root of tthe flame (18). The lower mouth of the bell, encirling the root of the flame in the floor (16) around the borehole from which oil emerges, can be pressed in and is closed in a sealed manner. ADVANTAGE - For extiniguishing oil well fires by encircling the root of the flame and smothering it.
