The present application relates to the technical field of fire-fighting maintenance, and particularly relates to an automatic jigger device and method for a fire-fighting water pump, which comprises a mounting unit, the mounting unit comprising a fixed
pipe and a mounting box, a switch valve arranged on the fixed
pipe, a connecting
assembly arranged between the fixed
pipe and the mounting box, and a drain pipe arranged at the bottom of the mounting box; and a jigger unit, the jigger unit comprising a rotating shaft rotatably arranged in the mounting box, a fixing
assembly arranged in the rotating shaft, and a plurality of blades arranged on the rotating shaft; the connecting
assembly is matched with the blades. The automatic jigger device and method for the fire-fighting water pump, by fixing and
welding the fixed pipe with the outlet main pipe network of the fire-fighting water pump, high-pressure water in the main pipe network is used to
impact the blades through the connecting assembly to drive the rotating shaft to rotate, the fixing assembly is connected with the driving pump shaft of the fire-fighting water pump to drive the driving pump shaft to rotate, and the jigger function is realized.
