Description

Technical Field

[0001] The utility model relates to the technical field of water cannon flow regulation, in particular to an electric control regulating device for water cannon flow. Background Art

[0002] Waterproof cannon is a fire extinguishing equipment that uses water as a medium to extinguish fires at a long distance. It uses a certain pressure and a certain amount of water, through energy conversion, and is ejected from the cannon head and nozzle at a very high speed to form a jet, thereby achieving the purpose of extinguishing fires at a certain distance. The fire water cannon has two spray functions: direct current and blooming. When spraying water columns, it can extinguish long-distance solid fires; when spraying blooming water mist, it can be used to cool the fire scene. It is widely used in flammable and explosive petrochemical enterprises, oil tank areas, oil terminals, hangars, ships and other places as well as fire-prone areas.

[0003] Currently, when using fire water monitors, the traditional way to adjust the flow of fire water monitors is generally to manually move the ball head plate to rotate the adjusting wheel, and the rotation of the adjusting wheel moves the flow valve inside the monitor head to change the flow of the monitor head. This adjustment method is not only time-consuming and labor-intensive, but also because the monitor head is generally located at the fire scene, manual close-range adjustment also has a certain risk factor. Therefore, those skilled in the art provide a water monitor flow electronic control device to solve the problems raised in the above background technology. Utility Model Content
