Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrogeological exploration technology, specifically to a layered water-stopping device for hydrogeological exploration. Background Technology
[0002] In hydrogeological surveys of areas with multiple aquifers, it is necessary to conduct observations and pumping tests for each aquifer separately in order to obtain data on water quantity, water level, water quality, and water temperature. This is called stratified water sealing, and stratified water sealing devices are required when performing stratified water sealing.
[0003] Currently, when performing layered water sealing, a water-stopping sleeve needs to be inserted into the borehole. The outer diameter of the water-stopping sleeve is slightly smaller than the diameter of the borehole to ensure smooth insertion. After the water-stopping sleeve is placed in the borehole, a stabilizer needs to be installed on the outside of the water-stopping sleeve to keep it centered in the borehole and prevent it from making eccentric contact with the borehole wall, which would affect the water sealing effect. The installation of the stabilizer requires constant adjustment of the position of the water-stopping sleeve, which is quite troublesome. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a layered water-stopping device for hydrogeological exploration, comprising: a pipe body and two water-stopping rubber rings installed on the outer wall of the pipe body, and further comprising: an installation plate installed on the inner wall of the pipe body, wherein a driving component is installed on the inner wall of the pipe body, and multiple equidistant sliding openings are opened on the top outer wall of the installation plate, a support component is slidably connected to the inner wall of the sliding openings, and one end of the support component is rotatably connected to the outer wall of the driving component, an opening and closing component is installed on the bottom outer wall of the installation plate, and four partition plates are installed on the inner wall of the pipe body, the four partition plates dividing the pipe body into a first water storage chamber and a second water storage chamber, and two water inlet holes are opened on both sides of the outer wall of the pipe body, and filter screens are installed on the inner walls of the four water inlet holes.
[0006] The drive assembly includes a motor, a threaded rod connected to the bottom of the motor output shaft, and a hexagonal block screwed onto the threaded rod.
[0007] The support assembly includes a slider, a connecting rod rotatably mounted on the top of the slider, a push plate mounted on the bottom of the slider, and a support plate mounted on one end of the push plate.
[0008] The opening and closing assembly includes an electric push rod, a movable rod installed at the bottom of the piston rod of the electric push rod, sealing plates installed at both ends of the outer walls on both sides of the movable rod, and two sealing rings installed on the outer walls of the movable rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This utility model discloses a stratified water-stopping device for hydrogeological exploration. A pipe body can be inserted into a borehole. After insertion, a drive assembly can be activated to simultaneously move multiple support components outwards, causing these support components to contact the inner wall of the borehole and provide support. This keeps the pipe body in a centered position within the borehole, making it easy and quick to straighten. During the descent of the pipe body, the opening and closing assembly can block the water inlet holes on both sides of the outer wall, preventing water from entering the pipe body before stratification, thus avoiding inaccurate subsequent water sampling.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figure 1-5This utility model provides a layered water-stopping device for hydrogeological exploration, comprising: a pipe body 1 and two water-stopping rubber rings 2 installed on the outer wall of the pipe body 1, and an installation plate 3 installed on the inner wall of the pipe body 1. A driving component 4 is installed on the inner wall of the pipe body 1, and multiple equidistant sliding ports 5 are opened on the top outer wall of the installation plate 3. A support component 6 is slidably connected to the inner wall of the sliding ports 5, and one end of the top of the support component 6 is rotatably connected to the outer wall of the driving component 4. An opening and closing component 7 is installed on the bottom outer wall of the installation plate 3, and four partition plates 8 are installed on the inner wall of the pipe body 1. The four partition plates 8 divide the pipe body 1 into a first water storage chamber 9 and a second water storage chamber 10. Two water inlets are opened on both sides of the outer wall of the pipe body 1, and filter screens 11 are installed on the inner walls of the four water inlets.
[0021] It should be noted that: the pipe body 1 can be placed into the borehole. After placement, the drive component 4 can be activated to simultaneously move multiple support components 6 to the outside of the pipe body 1, so that the multiple support components 6 contact the inner wall of the borehole and provide support, keeping the pipe body 1 in a centered position in the borehole. This makes it convenient and quick to straighten the pipe body 1. After the pipe body 1 is lowered into the borehole, the two water-stop rubber rings 2 undergo elastic deformation under the pressure of the borehole wall, thus tightly fitting against the borehole wall and providing a water-stopping function. During the descent of the pipe body 1, the opening and closing component 7 can block the water inlet holes on both sides of the outer wall of the pipe body 1 to prevent water from entering the pipe body 1 before stratification, which would lead to inaccurate water sampling later. When it is necessary to sample water from different water layers, the water inlet holes on both sides of the outer wall of the pipe body 1 can be opened through the opening and closing component 7. Water from different water layers enters the first water storage chamber 9 and the second water storage chamber 10 respectively through the water inlet holes at different heights. The filter screen 11 can filter impurities in the water.
[0022] In a preferred embodiment, the drive assembly 4 includes a motor 401, a threaded rod 402 connected to the bottom of the output shaft of the motor 401, and a hexagonal block 403 screwed onto the threaded rod 402.
[0023] It should be noted here that motor 401 can drive threaded rod 402 to rotate.
[0024] In a preferred embodiment, the support assembly 6 includes a slider 601, a connecting rod 602 rotatably mounted on the top of the slider 601, a push plate 603 mounted on the bottom of the slider 601, and a support plate 604 mounted on one end of the push plate 603.
[0025] It should be noted that when the threaded rod 402 rotates, it can drive the hexagonal block 403 to descend, which in turn pushes the slider 601 to move through the connecting rod 602, thereby pushing the support plate 604 towards the inner wall of the borehole.
[0026] In a preferred embodiment, the opening and closing assembly 7 includes an electric push rod 701, a movable rod 702 mounted on the bottom of the piston rod of the electric push rod 701, sealing plates 703 mounted on both ends of the outer walls of the movable rod 702, and two sealing rings 704 mounted on the outer walls of the movable rod 702.
[0027] It should be noted that the electric push rod 701 can drive the movable rod 702 to rise, which in turn drives the sealing plate 703 to rise, opening the water inlet holes on both sides of the outer wall of the pipe body 1. At the same time, the sealing ring 704 rises and is pressed on the partition plate 8, which can seal the connection between the movable rod 702 and the partition plate 8.
[0028] Working principle: The pipe body 1 can be placed into the borehole. After placement, the motor 401 can be started to drive the threaded rod 402 to rotate. The rotation of the threaded rod 402 can drive the hexagonal block 403 to descend, which in turn pushes multiple sliders 601 to move through multiple connecting rods 602. This pushes multiple support plates 604 towards the inner wall of the borehole, so that the support plates 604 contact the inner wall of the borehole and provide support, keeping the pipe body 1 in a centered position in the borehole. It is convenient and quick to straighten the pipe body 1. After the pipe body 1 is lowered into the borehole, the two water-stopping rubber rings 2 undergo elastic deformation under the pressure of the borehole wall, thus tightly fitting against the borehole wall and providing a water-stopping function. The sealing plate 70 3. During the descent of the pipe body 1, the water inlet holes on both sides of the outer wall of the pipe body 1 can be blocked to prevent water from entering the pipe body 1 before stratification, which would lead to inaccurate water sampling later. When it is necessary to sample water from different water layers, the electric push rod 701 can drive the movable rod 702 to rise, which in turn drives the sealing plate 703 to rise, opening the water inlet holes on both sides of the outer wall of the pipe body 1. At the same time, the sealing ring 704 rises and is pressed on the partition plate 8, which can seal the connection between the movable rod 702 and the partition plate 8. Water from different water layers enters the first water storage chamber 9 and the second water storage chamber 10 through the water inlet holes at different heights, respectively. The filter screen 11 can filter impurities in the water.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
