Rapid mud discharging device of underground sump for mining

The invention relates to the technical field of mine mining engineering, in particular to an underground sump quick sludge discharge device for mine mining, which comprises a pipeline dredger and a first fixing plate. An air pump works to convey air into an air inlet through a connecting pipe, at the moment, an air bag ring is stressed to expand until the air bag ring is completely attached to the inner wall of a to-be-cleaned pipeline, a servo motor is started until a cleaning ring plate is attached to the inner wall of the to-be-cleaned pipeline, a second motor is started, and the second motor works to drive a first fixing shaft to rotate; at the moment, a first fixing shaft drives a second fixing plate to rotate, then a third fixing plate and a sweeping ring plate are driven to rotate, the first fixing shaft rotates to drive a reciprocating lead screw to synchronously rotate, and at the moment, the inclined faces of a second clamping block and a first clamping block inserted into the outer side of the shaf
