Double-rotation water curtain spraying device

The utility model relates to the technical field of fire-fighting robots, in particular to a double-rotation water curtain spraying device which comprises a base assembly, a first-stage spraying assembly and a second-stage spraying assembly, and a first water guide groove is formed in the circumference of the side, close to the first-stage spraying assembly, of the base assembly. A second water guide groove is formed in the circumference of one side, close to the second-stage spraying assembly, of the first-stage spraying assembly; the base assembly, the first-stage spraying assembly and the second-stage spraying assembly are connected through first bolts, the base assembly is provided with a first water guide hole, and the first-stage spraying assembly is provided with a second water guide hole. Due to the use of the double atomization gear rings, the spraying range can be enlarged, the hovering time can be prolonged, and the fight ability of the robot approaching fire operation can be improved; meanwhile, t
