The modularized fire extinguishing
capsule comprises a hoop body and swallow-
tail-shaped embracing arms integrally formed on the left outer wall and the right outer wall of the hoop body, and a fire extinguishing
capsule body filled with
liquid carbon dioxide is installed on the outer wall of the side, away from the hoop body, of each swallow-
tail-shaped embracing arm. A one-way valve used for being filled with
liquid carbon dioxide is installed at the top end of the fire extinguishing
capsule body, and a
fire sprinkler is installed at the bottom end of the fire extinguishing capsule body. According to the fire extinguishing capsule, the specially designed hoop body is installed on a forest tree, when the temperature of a fire source rises, the
glass tube at the bottom end of the fire extinguishing capsule can cause the thermosensitive liquid to expand and crack due to temperature rise, and therefore
liquid carbon dioxide in the capsule makes contact with outside air, is gasified and is sprayed out through the spray head; by means of the automatic triggering mechanism, the fire extinguishing process is more intelligent and does not depend on manual intervention, and the risk of firefighters is greatly reduced.
