Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of groundwater sampling equipment technology, and more specifically, to a layered water-stopping device for hydrogeological drilling. Background Technology

[0002] Hydrogeology is a branch of geology that refers to the various changes and movements of groundwater in nature. It mainly studies the distribution and formation patterns of groundwater. In recent years, hydrogeology has permeated with research on geothermal, earthquake, and environmental geology, forming several new fields.

[0003] Currently, operators frequently need to use water-stopping devices when drilling and studying hydrogeology. While existing water-stopping devices have basic groundwater extraction capabilities, they cannot extract groundwater from different depths in a single operation. This forces operators to first extract groundwater from a fixed depth, then raise the device to the surface to drain the extracted groundwater, and then lower the device back into the groundwater for a second extraction. This process is inconvenient for operators and therefore needs improvement. Utility Model Content

The bottom end of the rotating shaft passes through the protective cover and extends to the outside of the bottom end of the protective cover, and a hollow block is fixedly sleeved on its outer surface. The interior of the hollow block is movably connected to the outer surface of the round shaft.

[0006] As a preferred embodiment of this utility model, a connecting pipe is fixedly connected to the inside of the top of the rectangular block, and the top of the connecting pipe passes through the rectangular block and extends to the outside of the top of the rectangular block.

[0008] As a preferred technical solution of this utility model, a second one-way valve is fixedly connected to the bottom of the inside of the right side of the box, and the right end of the second one-way valve passes through the box and extends to the outside of the right side of the box.

[0009] As a preferred technical solution of this utility model, filter plates located to the left of the first one-way valve and the second one-way valve are fixedly connected to both the upper and lower ends of the inner right side of the inner surface of the box. There are two filter plates, and the two filter plates are the same size.

[0012] As a preferred embodiment of this utility model, a long rod is fixedly sleeved on the outer surface of the rotating shaft, and a moving rod is hinged to the other end of the long rod.

[0013] As a preferred technical solution of this utility model, the other end of the moving rod is hinged to a long block, and the upper and lower ends of the front of the long block are fixedly connected to movable rods.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] 1. In this disclosure, by setting up a moving block, a round rod, and a first motor, when the moving block is located at the top of the second water pipe, the operator can extract groundwater from the cavity at the top of the partition through the connecting pipe. When the operator needs to extract groundwater from the cavity at the bottom of the partition, the first motor is started, which will cause the rotating shaft and the hollow block to rotate, thereby causing the inner surface of the hollow block to squeeze and push the outer surface of the round shaft, which in turn causes the round shaft to drive the connecting block, the round rod, and the moving block to move to the left, so that the bottom of the moving block moves to the top of the first water pipe, thereby removing the obstruction to the top of the second water pipe and obstructing the top of the first water pipe, so that the operator can extract groundwater from the cavity at the bottom of the partition through the connecting pipe.

[0017] 2. In this disclosure, by setting up a second motor, a long rod, a moving rod, a movable rod, and brush blocks, the operator starts the second motor, which causes the rotating shaft to drive the long rod to rotate, thereby causing the moving rod to drive the long block, the two movable rods, and the two brush blocks to move forward. When the operator uses the second motor to return the rotating shaft, the long rod, and the moving rod to their initial state, the two movable rods will drive the two brush blocks to move backward. This repetitive motion will allow the outer surfaces of the two brush blocks to clean the outer surfaces of the two filter plates, thereby preventing the outer surfaces of the two filter plates from becoming clogged after prolonged filtration.

[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0031] like Figures 1-5 The diagram illustrates a layered water-stopping device for hydrogeological drilling according to an embodiment of this disclosure. It includes a housing 1, with a partition 2 fixedly connected to the center of the housing 1's inner cavity. A rectangular block 3 is fixedly connected to the top of the housing 1. A first water pipe 4 and a second water pipe 5 are fixedly installed on the left and right sides of the bottom of the rectangular block 3, respectively. The bottom end of the first water pipe 4 passes through the rectangular block 3 and the housing 1 sequentially, extending to the outside of the top of the inner surface of the housing 1. The bottom end of the second water pipe 5 passes through the rectangular block 3, the housing 1, and the partition 2 sequentially, extending to the outside of the bottom of the partition 2. A movable block 7 is movably connected to the right side of the interior of the rectangular block 3. A round rod 8 is fixedly connected to the left side of the moving block 7. The left end of the round rod 8 passes through the rectangular block 3 and extends to the outside of the left side of the rectangular block 3 and is fixedly connected to the connecting block 9. A round shaft 10 is fixedly installed at the top of the connecting block 9. A protective cover 11 is fixedly installed on the left side of the top of the housing 1. A first motor 12 is fixedly installed inside the protective cover 11. A rotating shaft 13 is fixedly sleeved at the other end of the output shaft of the first motor 12. The bottom end of the rotating shaft 13 passes through the protective cover 11 and extends to the outside of the bottom end of the protective cover 11. A hollow block 14 is fixedly sleeved on the outer surface. The interior of the hollow block 14 is movably connected to the outer surface of the round shaft 10.

[0032] When the operator starts the first motor 12, the rotating shaft 13 and the hollow block 14 will rotate. This causes the interior of the hollow block 14 to compress and push the outer surface of the round shaft 10, which in turn causes the round shaft 10 to drive the connecting block 9, the round rod 8, and the moving block 7 to move to the left. This causes the bottom end of the moving block 7 to move above the top of the first water pipe 4, thus blocking the first water pipe 4. This allows the second water pipe 5 to extract groundwater from the cavity at the bottom of the partition 2. When the operator controls the first motor 12 to return the rotating shaft 13 and the hollow block 14 to their initial state, the first water pipe 4 can then extract water from the cavity at the top of the partition 2, thus achieving stratified pumping operation.

[0033] In some examples, a connecting pipe 6 is fixedly connected to the inside of the top of the rectangular block 3, and the top of the connecting pipe 6 passes through the rectangular block 3 and extends to the outside of the top of the rectangular block 3.

[0034] When the operator connects and fixes the extendable pumping hose to the connecting pipe 6, the connecting pipe 6 will extract groundwater from the top cavity or the bottom cavity of the partition 2 respectively.

[0035] In some examples, a one-way valve 15 is fixedly connected to the top of the inside right side of the housing 1, and the right end of the one-way valve 15 passes through the housing 1 and extends to the outside of the right side of the housing 1.

[0036] When the operator opens the first check valve 15, groundwater will enter the cavity at the top of the partition 2.

[0037] In some examples, a second check valve 16 is fixedly connected to the bottom of the inside right side of the housing 1. The right end of the second check valve 16 passes through the housing 1 and extends to the outside of the right side of the housing 1.

[0038] When the operator opens the second check valve 16, groundwater will enter the cavity at the bottom of the partition 2.

[0039] In some examples, filter plates 17 located to the left of one-way valve 15 and one-way valve 16 are fixedly connected to the upper and lower ends of the inner right side of the inner surface of the housing 1. There are two filter plates 17, and the two filter plates 17 are the same size.

[0040] The design of the two filter plates 17 enables the filtration of groundwater extracted by the first check valve 15 and the second check valve 16, thereby improving the subsequent test results for the operators.

[0041] In some examples, a protective cover 18 is fixedly connected to the rear right side of the housing 1, and a second motor 19 is fixedly installed inside the protective cover 18.

[0042] Due to the design of the protective cover 18, the second motor 19 can be effectively waterproofed.

[0043] In some examples, the other end of the output shaft of the second motor 19 is fixedly fitted with a rotating shaft 20, the left end of which passes through the protective cover 18 and extends to the outside of the left side of the protective cover 18.

[0044] When the operator starts the second motor 19, the rotating shaft 20 will rotate.

[0045] In some examples, a long rod 21 is fixedly sleeved on the outer surface of the rotating shaft 20, and a moving rod 22 is hinged to the other end of the long rod 21.

[0046] When the rotating shaft 20 rotates, it will cause the long rod 21 to rotate as well.

[0047] In some examples, the other end of the moving rod 22 is hinged to a long block 23, and the upper and lower ends of the front of the long block 23 are fixedly connected to a movable rod 24. The other end of the movable rod 24 passes through the box 1 and extends into the interior of the box 1 and is fixedly connected to a brush block 25. The outer surface of the movable rod 24 is movably connected to the interior of the box 1.

[0048] When the long block 23 moves, it will cause the two movable rods 24 and the two brush blocks 25 to move together.

[0049] In some examples, the outer surface of the moving block 7 and the inner surface of the rectangular block 3 are both smooth, and the outer surfaces of the first water pipe 4 and the second water pipe 5 are both fixedly connected to the inside of the top of the box 1.

[0050] Since both the outer surface of the moving block 7 and the inner surface of the rectangular block 3 are smooth, the movement of the moving block 7 inside the rectangular block 3 is smoother.

[0051] Working principle and usage process of this utility model:

[0052] First, the operator connects and secures the extendable pumping hose to the outer surface of the connecting pipe 6. Then, the operator uses a lifting device to lower the entire tank 1 into the groundwater. When the first check valve 15 reaches the first depth, it is opened. At this point, the extendable pumping hose will pump groundwater through the connecting pipe 6 and the first water pipe 4 into the cavity at the top of the partition 2. Subsequently, when the tank 1 continues to move downwards to the second depth, the first motor 12 is started, causing the rotating shaft 13 and the hollow block 14 to rotate, thereby... The inner surface of the hollow block 14 presses against the outer surface of the round shaft 10, which in turn causes the round shaft 10 to move the connecting block 9, the round rod 8, and the moving block 7 to the left. This causes the bottom end of the moving block 7 to leave the top of the second water pipe 5 and block the top of the first water pipe 4. At this time, the second one-way valve 16 is opened and the extendable pumping hose is used to pump the groundwater at the second depth into the cavity at the bottom of the partition 2 through the second water pipe 5 and the second one-way valve 16. This operation enables the stratified sampling and water-stopping of groundwater during geological drilling.

[0053] Finally, to prevent the two filter plates 17 from becoming clogged after prolonged operation, the operator starts the second motor 19, which will cause the rotating shaft 20 and the long rod 21 to rotate. This will cause the moving rod 22 to drive the long block 23, the two movable rods 24, and the two brush blocks 25 to move forward. Then, the operator uses the second motor 19 to return the rotating shaft 20, the long rod 21, and the moving rod 22 to their initial state. This will cause the two movable rods 24 to drive the two brush blocks 25 to move backward. This repetitive motion will allow the outer surfaces of the two brush blocks 25 to clean the outer surfaces of the two filter plates 17.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
