High-altitude projection fire extinguishing equipment

The invention provides high-altitude projection fire extinguishing equipment. The equipment comprises a bracket, a projection device, a crushing device positioned above the projection device and connected with a feeding port of the projection device, a feeding box positioned above the crushing device and connected with a feeding port of the crushing device, a first hot air balloon positioned abovethe feeding box and a first pull rope connected between the first hot air balloon and the bracket, wherein a discharge port of the projection device is vertically arranged downwards or obliquely arranged downwards relative to the horizontal plane. By arrangement of the first hot air balloon, the projection device can be drawn to a position right above or lateral above a fire site to project sandfrom top to bottom. The projection force needs not to overcome gravity action, and can form joint force with gravity to push the sand to move down. The grounding impact force is relatively large, barriers can be easily broken
