Description

Technical Field

[0001] This invention relates to soil sampling technology for geological exploration, and more specifically to a convenient sampling device for hydrogeological exploration. Background Technology

[0002] In hydrogeological exploration, soil sampling is a crucial step in obtaining information about underground soil and analyzing its geological structure and composition. The quality of the samples directly affects the accuracy and reliability of subsequent geological research, engineering planning, and resource development.

[0003] Existing soil sampling devices have limitations in practical applications, making it difficult to meet diverse sampling needs. For example, traditional sampling devices fall short when dealing with fluid, pasty soil. Due to the high fluidity of the soil, the pasty soil cannot be effectively stored in the sampling tube during the sampling process. This is because the pasty soil has a certain degree of fluidity; when it enters the sampling tube and the tube is pulled upwards, the fluid soil flows downwards under gravity, making it difficult to remain stably in the sampling tube. This makes portable sampling of fluid, pasty soil impossible, significantly complicating the sampling process. Summary of the Invention

[0004] The purpose of this invention is to provide a convenient sampling device for hydrogeological exploration, so as to solve the problem that the existing technology cannot sample the paste-like soil in a fluid state in the soil layer.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a convenient sampling device for hydrogeological exploration, comprising a mounting plate, a universal wheel fixedly connected to the bottom of the mounting plate, a threaded rod rotatably connected to the mounting plate, a transmission plate threadedly fitted onto the threaded rod, a guide rod slidably connected to the transmission plate and fixedly connected to the mounting plate, a first driving mechanism connected to the mounting plate and driven by the outer surface of the threaded rod, the first driving mechanism driving the threaded rod to rotate, an installation tube rotatably connected to the transmission plate, a second driving mechanism connected to the transmission plate and driven by the outer surface of the installation tube, the second driving mechanism driving the installation tube to rotate, and a sampling tube threadedly connected to the installation tube;

[0006] Multiple conical sampling boxes are fixedly connected inside the sampling tube. A sampling port is opened on one side of each conical sampling box. A first transmission column is slidably connected inside the conical sampling box. A sealing plate is fixedly connected to the bottom end of the first transmission column. A first spring, which is fixedly connected to the sampling tube, is fixedly sleeved on the outer surface of the first transmission column. A first connecting ring is fixedly connected to the top end of the first transmission column. A sampling plate is rotatably connected to the sealing plate. A flexible rubber cloth, which is fixedly connected to the sealing plate, is fixedly connected to the outer surface of the sampling plate. A second spring, which is fixedly connected to the sealing plate, is fixedly connected to one side of the sampling plate. Multiple discharge holes are opened on the sampling plate. A pushing mechanism is provided inside the conical sampling box. The pushing mechanism is used to push the sampling plate.

[0007] Furthermore, the pushing mechanism includes a pushing box fixedly connected to the conical sampling box, a first transmission inclined block slidably connected inside the pushing box, a second transmission column slidably connected to the top of the first transmission inclined block and slidably connected to the pushing box, the second transmission column slidably connected to the sampling tube, a second connecting ring fixedly connected to the top of the second transmission column, a second transmission inclined block slidably connected to the pushing box on one side of the first transmission inclined block, a pushing column slidably connected to the pushing box on one side of the second transmission inclined block, and a third spring fixedly connected to the pushing box on one side of the second transmission inclined block.

[0008] Furthermore, multiple storage frames are fixedly connected inside the conical sampling box, and a rubber sealing ring is fixedly connected to one side of the sealing plate.

[0009] Furthermore, the first driving mechanism includes a driving box fixedly connected to the mounting plate, a first rotating shaft rotatably connected to the driving box, a first bevel gear fixedly sleeved at one end of the first rotating shaft, and a second bevel gear fixedly sleeved on the outer surface of the first bevel gear.

[0010] Furthermore, the second driving mechanism includes a rotating driving component fixedly connected to the transmission plate. The output end of the rotating driving component is fixedly connected to a second rotating shaft. A first gear is fixedly sleeved on the outer surface of the second rotating shaft. A second gear fixedly sleeved on the outer surface of the first gear is meshed with the mounting tube.

[0011] Furthermore, a sampling groove is provided at the bottom end of the sampling tube.

[0012] Furthermore, multiple connecting plates are fixedly connected to the mounting plate, and support bolts are threaded onto the connecting plates. A support plate is fixedly connected to the bottom end of the support bolts.

[0013] Furthermore, a push handle is fixedly connected to the top of the mounting plate, and a scale post that is slidably connected to the transmission plate is fixedly connected to the mounting plate.

[0014] Compared with the prior art, the convenient sampling device for hydrogeological exploration provided by the present invention has the following beneficial effects:

[0015] This portable sampling device excels when sampling muddy, paste-like soil. Traditional sampling tools struggle to obtain sufficient samples in such conditions, but this device solves this problem through its unique design. After inserting the sampling tube, the side sampling port of the conical sampling box is opened first, allowing some of the paste-like soil to enter. Due to the surface tension of the paste-like soil, when only a small amount enters, the space formed by the sampling plate and the flexible rubber sheet can scoop up the soil. Then, the pushing mechanism activates, pushing the sampling plate to rotate and compress, forcing the paste-like soil into the conical sampling box under pressure, with some being ejected from the discharge port into the storage frame. Repeating this process multiple times ensures sufficient collection of paste-like soil samples, enabling portable and accurate sampling of paste-like soil at different depths, providing ample and accurate samples for subsequent soil testing at that depth.

[0016] This sampling device is widely applicable and can meet various soil sampling needs. When sampling pasty soil, the special sampling tube in Example 1 can be installed; for sampling normal soil, a conventional sampling tube can be installed. Operation is very convenient. The universal wheels allow the mounting plate to be easily moved to the desired sampling position, and rotating the support bolts moves the support plate downwards, ensuring stable support of the device. During sampling, the second drive mechanism rotates the mounting tube and sampling tube, while the first drive mechanism rotates the threaded rod, causing the transmission plate to lower the sampling tube. The scale column allows for precise control of the sampling depth, enabling portable sampling of soil at different depths. This design reduces the difficulty of operation for sampling personnel, improves sampling efficiency, and greatly facilitates hydrogeological exploration work. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Please see Figures 1 to 8 As shown, the present invention provides a convenient sampling device for hydrogeological exploration, including a mounting plate 1, a universal wheel 2 fixedly connected to the bottom of the mounting plate 1, a threaded rod 3 rotatably connected to the mounting plate 1, a transmission plate 4 threadedly engaged with the threaded rod 3, a guide rod 5 slidably connected to the transmission plate 4 and fixedly connected to the mounting plate 1, a first drive mechanism connected to the mounting plate 1 being driven to rotate the threaded rod 3 via a transmission connection to the outer surface of the threaded rod 3, the first drive mechanism being used to drive the threaded rod 3 to rotate, an installation tube 6 rotatably connected to the transmission plate 4, a second drive mechanism connected to the transmission plate 4 being driven to rotate the installation tube 6 via a transmission connection to the outer surface of the installation tube 6, the second drive mechanism being used to drive the installation tube 6 to rotate, a sampling tube 7 threadedly connected to the installation tube 6, and a sampling groove being opened at the bottom end of the sampling tube 7;

[0031] Multiple conical sampling boxes 8 are fixedly connected inside the sampling tube 7. A sampling port 9 is opened on one side of the conical sampling box 8. A first transmission column 10 is slidably connected inside the conical sampling box 8. A sealing plate 11 is fixedly connected to the bottom end of the first transmission column 10. A first spring 12, which is fixedly connected to the sampling tube 7, is fixedly sleeved on the outer surface of the first transmission column 10. A first connecting ring 13 is fixedly connected to the top end of the first transmission column 10. A sampling plate 14 is rotatably connected to the sealing plate 11. A flexible rubber cloth 15, which is fixedly connected to the sealing plate 11, is fixedly connected to the outer surface of the sampling plate 14. A second spring 16, which is fixedly connected to the sealing plate 11, is fixedly connected to one side of the sampling plate 14. Multiple discharge holes 17 are opened on the sampling plate 14. A pushing mechanism is provided inside the conical sampling box 8. The pushing mechanism is used to push the sampling plate 14.

[0032] The pushing mechanism includes a pushing box 21 fixedly connected to the conical sampling box 8. A first transmission inclined block 22 is slidably connected inside the pushing box 21. A second transmission column 23, which is slidably connected to the pushing box 21, is fixedly connected to the top of the first transmission inclined block 22. The second transmission column 23 is slidably connected to the sampling tube 7. A second connecting ring 24 is fixedly connected to the top of the second transmission column 23. A second transmission inclined block 25, which is slidably connected to the pushing box 21, is slidably connected to one side of the first transmission inclined block 22. A pushing column 26, which is slidably connected to the pushing box 21, is fixedly connected to one side of the second transmission inclined block 25. A third spring 27, which is fixedly connected to the pushing box 21, is fixedly connected to one side of the second transmission inclined block 25.

[0033] Multiple storage frames 18 are fixedly connected inside the conical sampling box 8, and a rubber sealing ring is fixedly connected to one side of the sealing plate 11.

[0034] When the soil at the sampling location is muddy, the process begins by installing the sampling tube 7 onto the installation tube 6. The second drive mechanism then rotates the installation tube 6, which in turn rotates the sampling tube 7. Simultaneously, the first drive mechanism rotates the threaded rod 3, which in turn moves the transmission plate 4 downwards. The transmission plate 4 then moves the installation tube 6 and the sampling tube 7, inserting the sampling tube 7 into the desired sampling location. Next, the first transmission column 10 moves downwards, causing the sealing plate 11 to move downwards. This opens the sampling port 9 on the side of the conical sampling box 8, allowing some muddy soil to pass through. 9 enters the conical sampling box 8, but due to the viscosity / surface tension of the paste-like soil, the amount of paste-like soil entering the conical sampling box 8 is relatively small. At this time, the first drive column 10 drives the sealing plate 11 to continue moving downward, inserting the sampling plate 14 on one side of the sealing plate 11 into the required sampling layer position. Then, the first drive column 10 drives the sealing plate 11 to move downward. At this time, the space formed by the sampling plate 14 and the flexible rubber cloth 15 scoops up the paste-like soil. Then, the sampling plate 14 is moved into the conical sampling box 8. Then, by pushing the second drive column 23 downward, the second drive column 23 drives the first drive inclined block 22 to move downward. Block 22 drives the second transmission inclined block 25 to move. At this time, the third spring 27 on the second transmission inclined block 25 is compressed. Simultaneously, the second transmission inclined block 25 drives the push column 26 to move. The push column 26 begins to push the sampling plate 14, and the sampling plate 14 rotates, squeezing the paste-like soil. At this time, the paste-like soil between the sampling plate 14 and the sealing plate 11 enters the conical sampling box 8 under pressure. At the same time, some soil is sprayed out from the discharge hole 17 on the sampling plate 14 under pressure and enters the multiple storage frames 18 in the conical sampling box 8 for storage. Then, the push column 26 stops squeezing the sampling plate 14. At this time, the sampling plate 14 moves to the second transmission inclined block 25. The spring 16 opens under its elastic force, and then drives the sampling plate 14 to move downward to take samples. This action is repeated to obtain sufficient paste-like soil from multiple conical sampling boxes 8. After sampling, the first drive column 10 moves upward under the elastic force of the first spring 12. The first drive column 10 drives the sealing plate 11 to seal the sampling port 9. Then the sampling tube 7 is pulled out, and the soil in the conical sampling box 8 is poured out. This enables portable and accurate sampling of paste-like soil at different depths, and obtains sufficient paste-like soil samples at that depth for subsequent soil quality testing.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the first drive mechanism includes a drive box 31 fixedly connected to the mounting plate 1. A first rotating shaft 32 is rotatably connected to the drive box 31. A first bevel gear 33 is fixedly sleeved at one end of the first rotating shaft 32. A second bevel gear 34 is meshed with the outer surface of the first bevel gear 33 and fixedly sleeved with the threaded rod 3.

[0037] The second drive mechanism includes a rotation drive component 41 fixedly connected to the transmission plate 4. The rotation drive component 41 is a servo motor, which is controlled by a PLC programming program. The servo motor can be controlled to rotate forward and backward and rotate at different angles. The output end of the rotation drive component 41 is fixedly connected to a second rotation shaft 42. A first gear 43 is fixedly sleeved on the outer surface of the second rotation shaft 42. A second gear 44 is fixedly sleeved on the outer surface of the first gear 43. The rotation drive component 41 drives the second rotation shaft 42 to rotate, and the second rotation shaft 42 drives the mounting tube 6 to rotate through the first gear 43 and the second gear 44.

[0038] Multiple connecting plates 51 are fixedly connected to the mounting plate 1. Support bolts 52 are threaded onto the connecting plates 51, and support plates 53 are fixedly connected to the bottom ends of the support bolts 52.

[0039] A push handle is fixedly connected to the top of the mounting plate 1, and a scale column that is slidably connected to the transmission plate 4 is fixedly connected to the mounting plate 1.

[0040] During the sampling process, the mounting plate 1 is first moved to the desired sampling position using the casters 2. Then, by rotating the support bolt 52, the support bolt 52 drives the support plate 53 to move downward, supporting the mounting plate 1 and achieving stable support for the sampling device. Subsequently, depending on the needs, when it is necessary to sample pasty soil, the sampling tube 7 in Embodiment 1 is installed on the mounting tube 6. When sampling normal soil, a normal sampling tube 7 can also be installed, improving the applicability of the sampling device. During the sampling process, the second drive mechanism drives the mounting tube 6 to rotate, and the mounting tube 6 drives the sampling tube 7 to rotate. At the same time, by rotating the first rotating shaft 32 on the first drive mechanism, the first rotating shaft 32 drives the threaded rod 3 to rotate through the first bevel gear 33 and the second bevel gear 34. The threaded rod 3 drives the transmission plate 4 to move downward, and the transmission plate 4 drives the mounting tube 6 and the sampling tube 7 to move. Then, the depth of descent is observed according to the scale column, so that the sampling tube 7 enters the required depth, thereby realizing portable sampling of soil at different depths by the sampling tube 7, which is convenient for sampling personnel to use.

[0041] Working principle: When the soil at the sampling location is muddy, the sampling tube 7 is first installed on the installation tube 6. Then, the second drive mechanism drives the installation tube 6 to rotate, which in turn drives the sampling tube 7 to rotate. Simultaneously, the first drive mechanism drives the threaded rod 3 to rotate, which in turn drives the transmission plate 4 to move downwards. The transmission plate 4 then moves the installation tube 6 and the sampling tube 7, thus inserting the sampling tube 7 into the desired soil sampling location. Subsequently, the first transmission column 10 moves downwards, which in turn drives the sealing plate 11 to move downwards. At this point, the sampling port 9 on the side of the conical sampling box 8 is opened, allowing some muddy soil to pass through. Sampling port 9 enters the conical sampling box 8, but due to the viscosity / surface tension of the paste-like soil, the amount of paste-like soil entering the conical sampling box 8 is relatively small. At this time, the first drive column 10 drives the sealing plate 11 to continue moving downward, inserting the sampling plate 14 on one side of the sealing plate 11 into the desired sampling layer position. Then, the first drive column 10 drives the sealing plate 11 to move downward. At this time, the space formed by the sampling plate 14 and the flexible rubber cloth 15 scoops up the paste-like soil. Then, the sampling plate 14 is moved into the conical sampling box 8. Then, by pushing the second drive column 23 downward, the second drive column 23 drives the first drive inclined block 22 to move downward. The moving inclined block 22 drives the second transmission inclined block 25 to move. At this time, the third spring 27 on the second transmission inclined block 25 is compressed. Simultaneously, the second transmission inclined block 25 drives the pushing column 26 to move. The pushing column 26 begins to push the sampling plate 14, and the sampling plate 14 rotates, squeezing the paste-like soil. At this time, the paste-like soil between the sampling plate 14 and the sealing plate 11 enters the conical sampling box 8 under pressure. At the same time, a portion of the soil is sprayed out from the discharge hole 17 on the sampling plate 14 under pressure and enters the multiple storage frames 18 in the conical sampling box 8 for storage. Subsequently, the pushing column 26 stops squeezing the sampling plate 14. At this time, the sampling plate 14... The two springs 16 open under their elastic force, and then drive the sampling plate 14 to move downwards again to take samples. This process is repeated to obtain sufficient paste-like soil from multiple conical sampling boxes 8. After sampling, the first drive column 10 moves upwards under the elastic force of the first spring 12. The first drive column 10 drives the sealing plate 11 to seal the sampling port 9. Then the sampling tube 7 is pulled out, and the soil in the conical sampling box 8 is poured out. This allows for portable and accurate sampling of paste-like soil at different depths, while obtaining sufficient paste-like soil samples at that depth for subsequent soil quality testing.

[0042] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
