Description

Technical Field

[0001] This utility model relates to the field of exploration drilling technology, and in particular to a downhole water extraction device for engineering exploration drilling. Background Technology

[0002] During engineering surveys, it is often necessary to obtain groundwater samples from the strata through drilling to study the impact of the groundwater on the rock and soil. Therefore, drilling well water sampling devices are required to obtain groundwater samples.

[0003] A search revealed a public disclosure (announcement) number: CN221840775U, which discloses a water extraction device for engineering exploration boreholes. The device includes a housing with water inlets on all four sides of the central portion. A limiting ring is fixedly connected to the lower end of the inner wall of the housing. Limiting rods are fixedly connected to the left and right sides of the inner wall of the housing, corresponding to the upper sides of the limiting rings. A piston is slidably connected inside the housing, with grooves on both sides. The inner walls of the grooves are slidably connected to the outside of the limiting rods. A top cover is provided on the top of the housing. In this invention, the protective components can filter the incoming water, preventing larger impurities from entering and affecting the quality of the extracted water. The fixing ring, filter cover, top cover, collection bottle, and housing are all fixed by threaded connections. The structure is simple, easy to disassemble, and allows for easy replacement of the filter cover. Different sized collection bottles can be used to adjust the water extraction volume.

[0004] Although the above solution can change the water volume by replacing the collection bottle with one of different sizes, it is not stable enough during drilling, it is not convenient to adjust the drilling area, and it is inconvenient to collect water and replace the collection bottle. Utility Model Content

[0005] The main purpose of this utility model is to provide a water extraction device for engineering exploration drilling wells. By setting up a drilling unit, it solves the problems of insufficient stability during drilling and inconvenient adjustment of the drilling area. By setting up a water extraction unit, it solves the problems of inconvenient water extraction and troublesome replacement of the collection bottle.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. In this utility model, by setting up a drilling unit, the first cylinder can be started before drilling to drive the load-bearing plate to move, and at the same time drive the drilling assembly to move, so as to conveniently select different positions for drilling. Then, the second cylinder is started to drive the second telescopic column to extend, which in turn drives the rotating motor and the drill bit to descend. At the same time, the rotating motor is started to drive the drill bit to rotate and start drilling. While the rotating motor is descending, the connecting ring drives the connecting block to move in the vertical groove, which improves the descending stability of the rotating motor and the drill bit, and further improves the drilling stability.

[0019] II. In this utility model, by setting up a water intake unit, after the drilling work is completed, the first cylinder is started to push the load-bearing plate to the other end of the slide groove, and then the third cylinder is started to drive the third telescopic column to descend. At this time, the limit plate passes through the corresponding positioning hole and drives the water receiving cup to collect water. When it is necessary to replace the water receiving cup, the insertion column can be removed to replace the water receiving cup. Attached Figure Description
