Description

Technical Field

[0001] The utility model relates to the technical field of hydrological survey and hydrological test, in particular to a multi-stage quick-change hydrological drilling water pump filter device. Background Art

[0002] In hydrological tests, pumping test is a common experimental method, which can be used to measure groundwater level, permeability coefficient and other characteristics. After the hydrological drilling is completed, the borehole is usually washed. Although the washing can mostly clean the sediment, rock debris and other particles on the hole wall and the bottom of the hole, when the pumping pump is placed in the predetermined position for the pumping test, the strong water flow will again draw the rock particles on the hole wall and the sediment particles that have not been cleaned at the bottom of the hole into the pumping pump, thereby blocking the pump, reducing the water output power of the pump, and even causing the pump to short-circuit and damage. This phenomenon is particularly prominent in broken formations.

[0003] Therefore, in order to prevent the rock debris, sediment and other particles on the borehole wall from easily entering the pump, a filter tube is usually placed on the borehole wall. The filter tube is placed from the borehole mouth. Multiple filter tubes (many small water-permeable holes drilled on the steel pipe) are connected to the section where the pump is placed. If the borehole is changed in diameter many times, tubes of different sizes need to be matched. The pumping section is generally a predetermined section position. Traditional filtration will connect the tube from the hole mouth to the predetermined pumping section. This is time-consuming for the deep buried pump and almost full coverage of the filter tube. The workload on site is huge (after the test is completed, the filter tube will be pulled out of the borehole section by section). In addition, different strata have particles of different particle sizes, and it is difficult for traditional tubes to quickly match water-permeable holes of different sizes.

[0004] Therefore, how to provide a multi-stage quick-change hydrological drilling pump filter device with a simpler and more reasonable structural design, more convenient construction operation, and efficient and able to quickly respond to different geological conditions has become a technical problem to be solved by technical personnel in this field.
