Fire water monitor

Abstract

The invention discloses a fire water monitor. The fire water monitor comprises a first motor assembly, a water monitor head assembly and a water monitor core assembly. The first motor assembly comprises a first shell, a first stator assembly, a first rotor assembly and a center shaft. A first end cover and a second end cover are arranged at the two ends of the first shell correspondingly, the first end of the first stator assembly is connected with the second end cover, the first rotor assembly is mounted on the outer portion of the first stator assembly in a sleeving manner, and the first rotor assembly and the first shell are rotationally connected. The water monitor head assembly comprises a first water monitor head and a second water monitor head, the first water monitor head is connected with the first stator assembly, the second water monitor head is mounted on the outer portion of the first water monitor head in a sleeving manner, the second water monitor head is in threaded connection with the first rotor assembly, and a first rotating stop device is arranged on the first water monitor head. The water monitor core assembly is arranged on the center shaft and cooperates withthe water monitor head assembly. By means of the arrangement, spray state switching of the fire water monitor is controlled by electric signals, switching is simpler and faster, the spray states of the fire water monitor can be precisely controlled so as to meet the requirements of various work environments, and the effect of saving energy and resources is achieved.

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.
