[0002] Coal mine is the most important solid fuel in China, and is a kind of combustible organic rock. A large number of mechanical and electrical equipment are often used in the process of coal mining, which produces a large amount of dust and smoke. These smoke is inhaled into the lungs of workers, which can cause damage to the body. At the same time, the conveyor belt equipment inside the coal mine needs to run at high speed in real time. Since most coal mines are underground, it is difficult to discharge the high temperature generated on the surface of the coal mine conveyor belt. Long-term high-temperature operation of the equipment can cause damage to the equipment. Moreover, the replacement of the equipment also requires a lot of money, causing additional economic losses.

When a fire occurs, the spraying device is manually started to make the spraying head spray liquid for fire extinguishing. However, manual inspection not only consumes a lot of labor, but also easily ignores some safety hazards. At the same time, when a fire occurs, the inspector often cannot arrive at the fire site in the first time, which leads to the risk of further spread of the fire.

In the event of a fire, the dual-purpose nozzle increases the number of hole structures and modifies some hole structures, causing the spray from these hole structures to change from a mist to a water column, increasing the spray distance and expanding the spray area.
