High-pressure water cannon for fire fighting truck

The high-pressure water monitor for the fire fighting truck belongs to the technical field of fire fighting water monitors and comprises a fire fighting truck body, a limiting rod is fixedly mounted on the top wall of the fire fighting truck body, a mounting ring is vertically and slidably mounted on the limiting rod, and a corrugated pipe is fixedly mounted on the bottom wall of the mounting ring; an elastic cushion matched with the corrugated pipe is fixedly mounted between the bottom wall of the mounting ring and the fire fighting truck body, and a connecting pipe is rotationally embedded in the top wall of the mounting ring. According to the scheme, through the elastic cushion, when the fire fighting truck body passes through a rugged mountain road, the fire fighting truck body shakes, the high-pressure water cannon can be buffered through the elastic cushion, and meanwhile the direction of the cannon head needs to be adjusted in time according to the fire behavior in the fire fighting work process; in th
