Zusammenfassung:	The utility mode relates to a there is the air sump pump in colliery underworkings uses high -efficient drainage device and can't satisfies power requirement, the poor just easy problem that burns outof blockking up of motor -driven pump adaptability when having solved the underworkings drainage of current colliery. Including a n precipitation bucket, n >= 3 just n is the integer, provided with the conduction pipe between an i precipitation bucket and the i+1 precipitation bucket, n 1 be provided with clean water pipe, i
