Description

Technical Field

[0001] This utility model relates to the field of hydrogeological exploration and stratified sampling, specifically to a stratified water-stopping device for geological exploration. Background Technology

[0002] During hydrogeological surveys, pumping tests are often used to determine hydrogeological parameters such as the permeability coefficient of aquifers in order to ascertain their permeability, inflow rate, groundwater movement characteristics, and hydraulic connections between aquifers. However, sampling from different water layers is not easily performed in a stratified manner, leading to reduced work efficiency. The prior art, application number CN202021124272.X, discloses a layered water-stopping device for hydrogeological exploration in coalfields with complex hydrogeological conditions. It includes a bottom pipe and an upper pipe, which are fixedly connected by a flange. Two first shells are symmetrically welded to the outer walls of both the bottom and upper pipes. A column is slidably connected to the inner wall of each first shell. A slider is welded to one end of the column, located inside the first shell, to apply pressure to the exploration well for fixation. The flange allows the upper second shell to filter and hold water from the phreatic layer, while the lower second shell filters water from the confined aquifer, separating the two water layers. A mesh is provided on the second plate to allow water from each layer to enter the layered water-stopping device. This invention provides more stable fixation and obtains more easily measurable moisture, thus improving the accuracy of the measurement data. However, the above solution still has its flaws. During the descent of the bottom and top pipes, the water in the upper layer will enter the lower partition through the second shell and filter plate, causing the water in the upper layer to mix with the water in the lower layer, resulting in inaccurate measurement data. In addition, the arrangement of the first shell, spring, column, slider, first plate and pulley has strict requirements on the inner diameter of the exploration well, resulting in poor applicability. Summary of the Invention

The lower end of the pressurized water intake pipe 170 is installed on the second filter head 180. The first sewage pipe 190 is also sealed through the lower partition 140. The second sewage pipe 191 is set on the first sewage pipe 190 and is located between the two partitions 140.

[0021] Example 2: A preferred embodiment of this utility model provides a layered water-stopping device for geological exploration, which differs from the above embodiments only in that: A limiting mechanism 130 is installed on the tube body 110. The limiting mechanism 130 is used to limit and fix the tube body 110. The limiting mechanism 130 includes an electric cylinder 131, a first box body 132 and a pulley 133. The cylinder barrel of the electric cylinder 131 is fixed on the tube body 110, and the piston rod end of the electric cylinder 131 is fixed on the outer wall of the first box body 132. The pulley 133 is rotatably mounted on the first box body 132. A storage groove 120 is provided on the tube body 110. The cylinder barrel of the electric cylinder 131 is fixed in the storage groove 120. The storage groove 120 facilitates the storage of the first box body 132 and the pulley 133.

[0022] Example 3: A preferred embodiment of this utility model provides a layered water-stopping device for geological exploration, which differs from the above embodiments only in that: The water inlet mechanism 192 is installed on the pipe body 110. The water inlet mechanism 192 allows water from different layers to enter different areas within the pipe body 110. The water inlet mechanism 192 includes an arc-shaped plate 1921, a second housing 1922, and a filter plate 1923. A second through hole 193 is provided on the pipe body 110. The second housing 1922 is fixed within the second through hole 193, and the filter plate 1923 is installed within the second housing 1922. The arc-shaped plate 1921 is slidably and sealingly inserted into the pipe body 110. The arc-shaped plate 1921 and the second housing 1923... Correspondingly, the arc plate 1921 has a first through hole 1924, which is correspondingly provided with the second box 1922. The second box 1922 has a mesh, and the tube 110 has a sliding groove 1925. The arc plate 1921 is slidably and sealed in the sliding groove 1925. It also includes a first lifting lug 194, the lower end of which is fixed to the upper surface of the arc plate 1921. The first lifting lug 194 facilitates lifting the arc plate 1921 from the tube 110.

[0023] In use, the lower end of the cable is installed on the second lifting lug 195, and the pipe body 110 is placed into the drilled detection well. During the lowering of the pipe body 110, the pulley 133 is completely retracted into the receiving groove 120. The smooth pipe body 110 facilitates its entry into the detection well. When the pipe body 110 descends to the designated position, the controller above controls the electric cylinder 131 to work. The extension of the piston rod of the electric cylinder 131 causes the pulley 133 to contact the inner wall of the detection well, thus fixing the pipe body 110 to the inner wall of the detection well. Then, the pull rod is used to hook the first lifting lug 194, and the pull rod is pulled to move the arc plate 1921 upward a designated distance, so that the first through hole 1924 aligns with the second box 1922, allowing water to enter the pipe body 110 through the second box 1922 and the filter plate 1923. The partition 140 separates the water from different layers. The submerged water intake pipe 150 and the pressurized water intake pipe 170 are respectively connected to external water pumps. The filter plate 1923 reduces the amount of mud and sand and other impurities entering the pipe body 110, which is beneficial for water quality testing. The first filter head 160 and the second filter head 180 further filter the impurities in the water. The first sewage pipe 190 is connected to an external sewage pump to discharge the mud and sand and some water blocked under the two baffles 140. This geological exploration layered water-stopping device uses the arc plate 1921 to effectively prevent water from entering the pipe body 110 during the descent process, ensuring that the water from different layers will not mix together. In addition, the electric cylinder 131 is used to fix the pipe body 110 in the exploration wells with different inner diameters. It has strong applicability and is easy to store the pulley 133, so that the pipe body 110 descends more smoothly.

Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
