Description

Technical Field

[0001] The utility model relates to the field of fire protection, and more specifically to a fire protection foam generator with a quick response function. Background Art

[0002] "Firefighting" means eliminating hidden dangers and preventing disasters (i.e. the general term for preventing and resolving man-made, natural and accidental disasters encountered by people in the process of life, work and study). Of course, the meaning of firefighting in people's early understanding is: (extinguishing) fire.

[0003] For example, the announcement number CN113769298A discloses an air foam generator for oil tank fire extinguishing, including an infusion tube, an outer sleeve connected to the top flange of the infusion tube, a foam sleeve fixedly mounted in the middle of the outer sleeve, a cover plate on the top of the foam sleeve, an outlet pipe connected to the bottom of the side of the foam sleeve, and a drain pipe connected to the other side of the bottom of the foam sleeve, a valve is provided on the drain pipe, and a foam generating tube is provided in the inner cavity of the outer sleeve. By arranging the outer sleeve and the foam generating tube between the infusion tube and the foam sleeve, and coordinating the structural design of the throttling piston ring, the nozzle and the nozzle in the foam generating tube, in the initial state, the air inlet groove and the filter ring are sealed by the outer sealing ring, so as to avoid the filter ring being exposed to the outside for a long time and being easily attached with a large amount of dust, which affects the amount of air entering when used in subsequent emergencies, and further affects the generation of foam, resulting in poor fire extinguishing efficiency and effect.

[0004] It can be seen from the above-mentioned public scheme that there is currently no limiting structure at the connection between the end cover and the foam sleeve of the fire foam generator, which causes the end cover to easily deviate from the foam sleeve when installing the end cover, making it inconvenient to load and unload the bolts and also reducing the stability of the installation connection. At the same time, the height of the foam sleeve is fixed, and it is not easy to adjust the height of the foam sleeve according to the use requirements, which brings a lot of inconvenience to use.
