Hydraulic ring geological drilling layered water pumping equipment

The invention relates to the technical field of geological survey, in particular to hydraulic ring geological drilling layering water pumping equipment which comprises an air cylinder and a water taking pipe with the lower end closed, the air cylinder is arranged on the lower portion of the water taking pipe, the water taking pipe is sleeved with two annular air bags, and a plurality of communicating pipes are arranged between the two annular air bags. A piston is arranged in the air cylinder, a piston rod is fixed to one side of the piston, and the other end of the piston rod penetrates through the outer wall of one side of the air cylinder and is connected with a balancing weight. Two first cables are fixed to one side of the balancing weight and penetrate through the water taking pipe, second cables are connected to the upper portions of the two sides of the water taking pipe, and the lower end of the water taking pipe is a water storage section. According to the water taking device, multiple water taking
