AI Technical Summary
When existing fire spraying devices spray fires, the spraying range of the nozzle is relatively limited, making it difficult to effectively eliminate flames in corners, and the spray water flow is small and the extinguishing speed is slow, which makes it difficult to control the fire.
An automatic sprinkler fire-fighting device is designed. By setting up a rotating component and a spray component, the sprinkler head can swing left and right during the spraying process, and the motor drives the rotating box to rotate to expand the spraying range. The spray assembly drives the spray box and nozzle to swing through the transmission gear and installation shaft to increase the spray range.
Through the design of the automatic sprinkler fire-fighting device, the spray range has been greatly increased, which can more effectively extinguish the flames in corners. The spray water flow is sufficient and the extinguishing speed is accelerated, which improves the efficiency and safety of fire control.
