Abstract

The application discloses a fire fighting water cannon. The fire fighting water cannon comprises a main pipeline, a spraying head, a first branch pipeline and a second branch pipeline; the main pipeline is provided with a first end and a second end; the spraying head is arranged at the first end; water mist spraying structures which are used for spraying out water mist and water column spraying structures which are used for spraying out water columns are arranged on the spraying head; the water mist and the water column can be sprayed out simultaneously; the first branch pipeline is connectedto the second end and can communicate with the main pipeline; the second branch pipeline is connected to the second end and can communicate with the main pipeline; and the second branch pipeline and the first branch pipeline are arranged in parallel. According to the fire fighting water cannon of the structure, the fire fighting effect is improved through combined use of column-mist, and the spraying distance of the water columns and / or water mist can be adjusted by changing water pressure, so that a fire fighting effect can be further improved; and therefore, the requirements on the emergencytreatment, such as safety, high-efficiency fire fighting / decontamination, in different places can be met better.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a fire-fighting water cannon. Background technique [0002] In the event of a fire, the most common fire extinguishing method is to use fire water cannons to spray water to extinguish the fire, which also includes two ways of spraying water jets to extinguish fires and spraying water mist to extinguish fires. Water jets are suitable for fires in large spaces and long distances Carry out fixed-point or scanning fire extinguishing, while water mist has good heat absorption, heat insulation, and oxygen insulation capabilities, and can pass through obstacles to reach the flame area, but the spraying distance is short, so spraying water mist fire extinguishing is suitable for extinguishing fires in nearby areas. This kind of fire extinguishing method is usually fixed installation and multi-point control. [0003] At present, the existing fire water monitors can only c...
