The invention provides a spraying gun and a fire extinguishing device and relates to the technical field of fire rescue. A spraying gun rod with a cavity is included; the side wall of the water outflow end of the spraying gun rod is provided with at least one water spraying hole; and the water spraying direction of the water spraying hole is formed in the radial direction of the spraying gun rod.In the technical scheme, the spraying gun adopts the spraying gun rod structure with the lateral water spraying hole, because combustion of smoldering fire is a spontaneous combustion heat source, forexample, when spontaneous combustion happens to some straw piles and grain piles, because of oxygen shortage of the interior environment, smoldering is performed at the initial stage of combustion, but, the spontaneous combustion heat source can become a heat source causing smoldering of other substances, when the spraying gun rod is used for fire extinguishment, the spraying gun rod can be inserted into the combustion substances, the interior of the combustion substances is cooled by means of water flow sprayed to the periphery, and finally, fire extinguishment on the smoldering fire is achieved. The spray gun is simple in structure, convenient to operate and capable of effectively performing fire extinguishment on the smoldering fire in the combustion substances and removing potential safety hazards.
Description
technical field [0001] The invention relates to the technical field of fire rescue, in particular to a spray gun and a fire extinguishing device. Background technique [0002] Fire refers to the disaster caused by burning out of control in time or space. Among various disasters, fire is one of the main disasters that most frequently and commonly threaten public safety and social development. [0003] Human beings can use and control fire, which is an important symbol of civilization progress. Therefore, the history of human use of fire and the history of fighting against fire go hand in hand. While using fire, people constantly summarize the law of fire occurrence and minimize fire and its harm to human beings. In the event of a fire, it is necessary to escape safely and as soon as possible. [0004] There are various forms of fire, among which smoldering is also a kind of burning, smoldering is a form of solid combustion, it is slow burning without visible light, usually...
