fire water cannon

Abstract

The invention discloses a fire-fighting water monitor, comprising: a first motor assembly, which includes a first housing, a first stator assembly, a first rotor assembly and a central shaft, and first end covers are respectively provided at both ends of the first housing and the second end cover, the first end of the first stator assembly is connected to the second end cover, the first rotor assembly is sleeved outside the first stator assembly, and the first rotor assembly is rotatably connected to the first housing; the nozzle assembly , which includes a first gun head and a second gun head, the first gun head is connected to the first stator assembly, the second gun head is sleeved on the outside of the first gun head, the second gun head is screwed to the first rotor assembly, and the second gun head is connected to the first rotor assembly. A gun head is provided with a first anti-rotation device; a gun core assembly is arranged on the central shaft and matches with the gun head assembly. With such a setting, the switching of the spraying state of the fire water monitor is controlled by an electric signal, which is simpler and quicker, and can accurately control the spraying state of the fire water monitor to meet the needs of various working environments and achieve the effect of saving energy and resources.

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] The fire-fighting water cannon is a fire-fighting equipment that converts pressure water through energy conversion and sprays it from the water outlet of the nozzle at a high speed to form a water jet, thereby extinguishing a fire at a certain distance. The fire water cannon mainly has two spraying states: columnar and mist. The columnar form can be used for remote fixed-point fire extinguishing. The mist form can isolate the disaster situation and prevent the further expansion of the disaster situation. The appropriate method can be selected through the disaster scene. However, the existing fire water monitors have poor operability in switching the jet flow mode at the nozzle head, and the switching is inconvenient. Therefore, how to solve the problem that the fire water monitor in the prior art is inco...

AI Technical Summary

Problems solved by technology

However, the operability of the existing fire water monitors to switch the jet flow mode at the nozzle head is poor, and the switching is inconvenient

Therefore, how to solve the problem that the fire water cannon in the prior art is inconvenient to switch the jet flow mode is urgently needed by those skilled in the art.
