automatic device for fighting fires in a forest.

摘要

An automatic device for fighting forest fires, comprising a supply of pressurized water, such as a water tank (1), connected to compressed gas cylinders (2) via a motorized valve. It includes a network of buried pipes (4) which supply a plurality of telescoping columns (5) having coaxial sliding tubes which carry a water diffuser (6). When not in use, the sliding tubes are folded into a casing (8) which is buried in the earth. The upper ends of the casings (8) are connected to the network of pipes (4). The outer sliding tube of each column carries a splined guide ring around the edge of its lower end. The device can be used to protect wooded areas such as parks, rest areas or the surroundings of a residential building against fires.
