[0002] Mobile fire water cannon is suitable for use in spaces where the fire scene is far from the water source and where fire trucks cannot enter. It is used to extinguish general solid material fires and oil fires, and is also used to cool oil tanks. The cannon has the characteristics of adjustable flow, long range, multiple functions, small size and good performance.

[0003] Since the location of the fire is not specific, when the fire occurs in an uneven location, the bottom of the fire monitor is fixed and difficult to adjust. When using the fire monitor, it is easy for the position to deviate due to the unstable installation area and the influence of the water pressure of the fire monitor, thus affecting the fire extinguishing work of the fire monitor.

[0004] For this reason, we propose a mobile fire monitor. Utility Model Content
