Abstract
The utility model discloses an automatic spraying fire-fighting hydraulic giant, comprising an inner pipe and an outer pipe which are arranged longitudinally. The outer pipe is sleeved outside the inner pipe; the inner pipe and the outer pipe can rotate reversely; high pressure water current goes into the inner pipe from a fire pipeline; vanes in the inner pipe rotate under the impact of the water current; a rotating shaft fixed with the vanes also rotates; the rotating shaft drives a first gear to rotate, which makes a second gear move on the first gear backwards and forwards; consequently, the rotation of the outer pipe in radial direction is realized; and after impacting the vanes, the water current goes into a pipe cap and then is sprayed out from a nozzle. Because the outer pipe can rotate in the radial direction backwards and forwards, the sprayed water column can change direction and the spraying range can be broader. The utility model can spray water to extinguish fire without manual operation and the spraying angle can change automatically.
