Same-diameter multi-time water pumping device for hydrogeological drilling

Abstract

The invention discloses a same-diameter multi-time water pumping device for hydrogeological drilling. The same-diameter multi-time water pumping device comprises a transmission rod in a regular hexagon shape; the drilling head is of a threaded structure and is fixedly arranged at the bottom of the transmission rod; the water taking assembly is arranged in the middle of the transmission rod and the drilling head and used for extracting water of different soil layers at the same time, the water taking assembly comprises a cavity, the cavity is formed in the middle of the transmission rod and the drilling head, and a plurality of water taking holes are evenly formed in the surface of the transmission rod and the surface of the drilling head in a staggered mode. When a transmission rod and a drilling head are drilled into a target position in soil, a water taking box is rotated at the moment, so that a water inlet hole corresponds to a water taking hole in position, meanwhile, the water taking box drives a rotating disc to rotate through cooperation of a gear ring and insections, and the rotating disc drives staggered teeth to prevent the water taking hole from being blocked; at the moment, water in the soil passes through the through hole from the water taking hole and enters the water taking box and the inner wall of the bottom cover through the water inlet hole to be collected, so that the aim of collecting water of different soil layers at the same time is achieved.

Description

technical field [0001] The invention relates to the technical field of drilling and pumping, in particular to a multiple pumping device of the same diameter for hydrogeological drilling. Background technique [0002] Hydrogeology, a branch of geology, refers to the phenomena of various changes and movements of groundwater in nature. Hydrogeology is the science of studying groundwater; special pumping devices are needed to extract and test the water at different levels in the ground to obtain its specific hydrogeological parameters. [0003] However, when the existing technology is actually used, most of the equipment can only absorb the water quality of different soil layers in sequence, but cannot extract the water quality of different soil layers at the same time, which wastes time, and some equipments simultaneously measure the water quality of different soil layers. During extraction, it is easy to cause cross-contamination of water quality in different soil layers, the...

[0003] However, when the existing technology is actually used, most of the equipment can only absorb the water quality of different soil layers in sequence, but cannot simultaneously extract the water quality of different soil layers, which is a waste of time, and some equipment are simultaneously measuring the water quality of different soil layers. When pumping, it is easy to cause cross-contamination of water quality in different soil layers, which will affect the test results
