[0044] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0045] According to a first aspect of the embodiment of the present application, an electrical testing device for unsaturated bentonite is provided, such as Figure 1 As shown, it includes: a bracket 100; a first electrode assembly 200, which is arranged on the bracket 100, and the first electrode assembly 200 is formed with a first test side, and the first test side is used to place the sample 10'; a second electrode assembly 300, which is arranged on the bracket 100, and the second electrode assembly 300 is formed with a second test side, and the second electrode assembly 300 can move relative to the bracket 100 to make the second test side approach or move away from the first test side; an isolation tube 400, which is slidably arranged on the second electrode assembly 300, and the second test side is located in the isolation tube 400, and one end of the isolation tube 400 is detachably covered on the first test side.

[0046] like Figure 1 As shown, the electrical testing device for unsaturated bentonite provided in the embodiment of the present application includes a bracket 100, a first electrode assembly 200, a second electrode assembly 300 and an isolation tube 400, wherein the first electrode assembly 200 is arranged on the bracket 100, and the first electrode assembly 200 is formed with a first test side for placing a sample 10', so that when testing the sample 10' of unsaturated bentonite, the experimenter can place the sample 10' on the first test side.

[0047] The second electrode assembly 300 is movably disposed on the bracket 100, and the second electrode assembly 300 is formed with a second test side. The second electrode assembly 300 can move relative to the bracket 100 to make the second test side approach or move away from the first test side. Therefore, when a sample 10' is disposed on the first test side and it is necessary to test the sample 10', the experimenter can manipulate the second electrode assembly 300 to move relative to the bracket 100 to move the second test side closer to the first test side so that the second test side abuts against the sample 10', measure the electrical signal parameters of the sample 10' through the first electrode assembly 200 and the second electrode assembly 300, and after the test is completed, the second test side is evacuated from the sample 10' by manipulating the second electrode assembly 300 to move relative to the bracket 100.

[0048] The isolation tube 400 is slidably disposed on the second electrode assembly 300, and the second test side is located in the isolation tube 400. One end of the isolation tube 400 is detachably covered on the first test side. Therefore, when the second test side abuts against the sample 10', the experimenter can further manipulate the isolation tube 400 to slide relative to the second electrode assembly 300, so that one end of the isolation tube 400 is covered on the first test side, so that the sample 10' is located inside the isolation tube 400. The isolation tube 400 is used to isolate the sample 10' on the first test side from the external environment to avoid evaporation and water loss of the sample 10' during the electrical test, so that the water content of the sample 10' can be relatively stable during the test, ensuring that the test result can correspond to the water content of the sample 10' recorded before the test, avoiding inaccurate test results caused by changes in the water content of the sample 10' during the test, improving the accuracy of the electrical test results of unsaturated bentonite, and providing reliable reference data for groundwater exploration and development operations.

[0049] It is understandable that unsaturated bentonite refers to bentonite with a water content less than that of saturated bentonite. Therefore, when conducting an electrical test on unsaturated bentonite, the test result needs to correspond to the water content of the unsaturated bentonite during the test to ensure that the test result can accurately characterize the electrical signal parameters of the unsaturated bentonite at a specific water content. If the sample 10' is exposed to a relatively open environment, the water in the sample 10' will evaporate and dissipate over time, causing the water content of the sample 10' to change, affecting the accuracy of the test result. The electrical test device for unsaturated bentonite provided in the embodiment of the present application can utilize the settings of the first electrode assembly 200, the second electrode assembly 300 and the isolation tube 400. During the test, the environment in which the sample 10' is located is limited to a small space surrounded by the first test side, the second test side and the inner side of the isolation tube 400, thereby greatly reducing the water loss of the sample 10' and achieving the accuracy improvement of the electrical test results of the unsaturated bentonite.

[0050] In some examples, such as Figure 1 As shown, the electrical method testing device for unsaturated bentonite also includes: a cylinder body 500, which is arranged on the bracket 100, the cylinder body 500 is used to contain deionized water 20', and the first test side is located in the cylinder body 500; a cylinder cover 600, which is detachably arranged on the cylinder body 500; wherein, when the cylinder cover 600 is arranged on the cylinder body 500, the cylinder cover 600 covers the cylinder mouth of the cylinder body 500.

[0051] like Figure 1As shown, the unsaturated bentonite electrical method testing device also includes a cylinder 500 and a cylinder cover 600, wherein the cylinder 500 is arranged on the bracket 100 and can be used to hold deionized water 20', the first test side of the first electrode assembly 200 is located inside the cylinder 500, and the cylinder cover 600 is detachably arranged on the cylinder 500, and when the cylinder cover 600 is arranged on the cylinder 500, the cylinder cover 600 covers the cylinder mouth of the cylinder 500, so that in the process of testing the sample 10', the experimenter can place the sample 10' on the first test side each time, and after adding deionized water 20' into the cylinder 500, cover the cylinder mouth of the cylinder 500 with the cylinder cover 600, so that the cylinder 500 is not detachable. 00, so that the sample 10' can lose water regularly in a relatively constant humidity environment. After the sample 10' reaches the target water loss, the cylinder cover 600 is removed from the cylinder body 500, and the second electrode assembly 300 is manipulated to move relative to the bracket 100, so that the second test side is abutted against the sample 10' for testing, and after the test is completed, the second test side is withdrawn relative to the first test side, and the cylinder cover 600 is re-covered on the cylinder mouth, so that the sample 10' loses water regularly again to prepare for the next test, thereby facilitating the testing of different water contents on the same sample 10' to obtain the required electrical signal parameters of the sample 10' under different water contents. At the same time, the sample 10' can be avoided from being moved between two adjacent tests, thereby reducing the possibility of damage and deformation of the sample 10' due to contact and collision, providing a guarantee for the structural consistency of the sample in multiple tests, and further improving the accuracy of the electrical test results of unsaturated bentonite.

[0052] It should be noted that the injection height of the deionized water 20 ′ is lower than the first test side to prevent the deionized water 20 ′ from contacting the sample 10 ′.

[0053] It is understandable that, when the cylinder body 500 is filled with deionized water 20' and the cylinder cover 600 covers the cylinder mouth, a certain humidity environment can be formed inside the cylinder body 500, and the water loss of the sample 10' under a certain humidity environment will form a relatively regular change with the water loss time. Therefore, before the electrical method test, the water loss of the sample 10' in the cylinder body 500 can be tested, and the change law of the water loss of the sample 10' with the water loss time can be statistically analyzed under different water injection heights of the deionized water 20'. Furthermore, during the electrical method test, it can be determined whether the water loss of the sample 10' in the cylinder body 500 has reached the target water loss according to the aforementioned change law, and when the sample 10' reaches the target water loss, the cylinder cover 600 is removed, and the sample 10' is tested using the first electrode assembly 200 and the second electrode assembly 300.

[0054] At the same time, when the cylinder 500 is filled with deionized water 20', it can also prevent the sample 10' from excessively losing water in the cylinder 500, reduce the possibility of the sample 10' losing water and cracking, ensure the integrity of the sample 10' during the test, and further improve the accuracy of the electrical test results.

[0055] In some possible examples, such as Figure 1 As shown, the electrical testing device for unsaturated bentonite also includes: a drain pipe 700 and a stop valve 800, wherein a drain hole is formed on the side wall of the cylinder body 500, the drain pipe 700 is passed through the drain hole, and the drain pipe 700 is connected to the interior of the cylinder body 500, and the stop valve 800 is arranged on the drain pipe 700, and the stop valve 800 is used to conduct or cut off the drain pipe 700. Thus, when the deionized water 20' in the cylinder 500 needs to be discharged, the stop valve 800 can be opened to allow the drain pipe 700 to be conductive. When the cylinder 500 does not need to be drained, the stop valve 800 can be closed to ensure that the water level in the cylinder 500 is stable, thereby making it convenient for the experimenter to adjust the water level in the cylinder 500 or empty the deionized water 20' in the cylinder 500, avoiding moving the cylinder 500 when adjusting the water level or draining water, and further reducing the possibility of contacting or damaging the sample 10' when the sample 10' is located in the cylinder 500, thereby providing further guarantee for improving the accuracy of the electrical test results of unsaturated bentonite.

[0056] In some examples, such as Figure 1 As shown, the first electrode assembly 200 includes: a first electrode plate 210, which is arranged in the cylinder body 500, the first electrode plate 210 is formed with a first connection side and a first test side, and a gap is formed between the first connection side and the bottom wall of the cylinder body 500; a first connecting tube 220, which is passed through the bottom wall of the cylinder body 500, one end of the first connecting tube 220 is connected to the first connection side, and the other end of the first connecting tube 220 is arranged on the bracket 100; a first wire 230, the bracket 100 is formed with a first threading hole 110 connected to the first connecting tube 220, the first wire 230 is passed through the first threading hole 110 and the first connecting tube 220 in sequence, and one end of the first wire 230 is connected to the first electrode plate 210.

[0057] like Figure 1As shown, the first electrode assembly 200 includes a first electrode plate 210, a first connecting tube 220 and a first wire 230, wherein the first electrode plate 210 is arranged in the cylinder body 500, and a first connecting side and a first testing side are formed on the first electrode plate 210, and a gap is formed between the first connecting side and the bottom wall of the cylinder body 500, and the first connecting tube 220 is penetrated through the bottom wall of the cylinder body 500, and one end of the first connecting tube 220 is connected to the first connecting side, and the other end is arranged on the bracket 100, so that the first connecting tube 220 is used to support the first electrode plate 210, and the setting stability of the first electrode plate 210 is improved. When deionized water 20' is injected into the cylinder body 500, the injection height of the deionized water 20' can be made lower than the first electrode plate 210, thereby avoiding the deionized water 20' from contacting the sample 10' on the first testing side, and ensuring the accuracy of the result of the electrical method test.

[0058] A first threading hole 110 connected to the first connecting tube 220 is formed on the bracket 100. The first wire 230 is sequentially inserted into the first threading hole 110 and the first connecting tube 220, and one end of the first wire 230 is connected to the first electrode plate 210, so that the first connecting tube 220 and the first threading hole 110 can be used to protect the first wire 230 and prevent the first wire 230 from contacting the deionized water 20', thereby improving the overall operating stability of the first electrode assembly 200.

[0059] In some feasible examples, a first connector 231 is provided at one end of the first wire 230 away from the first electrode plate 210 , and the first connector 231 can be used to connect a testing instrument, such as an impedance meter.

[0060] In some examples, the first connecting pipe 220 is sealedly connected to the cylinder body 500 .

[0061] By providing a sealed connection between the first connecting tube 220 and the cylinder body 500, water seepage at the connection between the first connecting tube 220 and the bottom wall of the cylinder body 500 can be avoided, and the deionized water 20' can be prevented from leaking out of the cylinder body 500. On the one hand, the humidity environment in the cylinder body 500 can be kept stable, and on the other hand, the workload of cleaning after the test can be reduced.

[0062] In some examples, such as Figure 1As shown, the second electrode assembly 300 includes: a micrometer 310, a measuring rod of the micrometer 310 is slidably inserted into the bracket 100; a second electrode plate 320, the second electrode plate 320 is formed with a second connecting side and a second testing side which are parallel to each other, the second connecting side is connected to the measuring rod, and the second connecting side is perpendicular to the axial direction of the measuring rod, and the second testing side is parallel to the first testing side; a second wire 330, the bracket 100 is formed with a second threading hole 120, the second wire 330 is inserted into the second threading hole 120, and one end of the second wire 330 is connected to the second electrode plate 320; wherein, the isolation tube 400 is slidably sleeved on the second electrode plate 320.

[0063] like Figure 1 As shown, the second electrode assembly 300 includes a micrometer 310, a second electrode plate 320 and a second wire 330, wherein the measuring rod of the micrometer 310 is slidably inserted into the bracket 100, and the second electrode plate 320 is formed with a second connecting side and a second testing side, and the second connecting side and the second testing side are parallel to each other, the second connecting side is connected to the measuring rod of the micrometer 310, and the second connecting side is perpendicular to the axial direction of the measuring rod, and the second testing side is parallel to the first testing side, and then when the measuring rod of the micrometer 310 undergoes axial displacement, the second testing side can be driven to move in a direction perpendicular to the first testing side, and when the second testing side abuts against the sample 10', the displacement generated by the measuring rod can be read using the indicator of the micrometer 310, and then the thickness of the sample 10' can be calculated, so as to obtain the thickness value of the sample 10'.

[0064] The bracket 100 is formed with a second threading hole 120, and the second wire 330 is passed through the second threading hole 120, and one end of the second wire 330 is connected to the second electrode plate 320, so that the second threading hole 120 can be used to protect the second wire 330 and extend the service life of the second wire 330. The isolation tube 400 is slidably sleeved on the second electrode plate 320, and the isolation tube 400 can be used to further protect the structure of the second electrode plate 320.

[0065] In some feasible examples, the first electrode plate 210 and the second electrode plate 320 are both circular plates with the same diameter, the first isolation tube 400 is a circular tube and the inner diameter of the first isolation tube 400 is the same as the diameter of the first electrode plate 210, the axial direction of the first electrode plate 210, the axial direction of the second electrode plate 320 and the axial direction of the isolation tube 400 are consistent, so that the isolation tube 400 can be further detachably sleeved on the outer peripheral wall of the first electrode plate 210, so as to achieve the covering of the first test side when the isolation tube 400 is sleeved on the outer peripheral wall of the first electrode plate 210, and further reduce the influence of the external environment of the isolation tube 400 on the sample 10'.

[0066] It is understandable that the micrometer 310 generally includes an indicator, a knob, and a measuring rod. By rotating the knob of the micrometer 310, the measuring rod can be axially displaced, thereby causing the indicator to produce a reading change.

[0067] In some feasible examples, the first wire 230 and the second wire 330 are both coaxial wires, so that the coaxial wires can be used to improve the transmission stability of the test signal.

[0068] In some feasible examples, a second connector 331 is provided at one end of the second wire 330 away from the second electrode plate 320 , and the second connector 331 can be used to connect a testing instrument, such as an impedance meter.

[0069] In some examples, such as Figure 1 As shown, the second electrode assembly 300 also includes: a second connecting tube 340, which is arranged on the bracket 100, and the second connecting tube 340 is connected to the second threading hole 120, the second wire 330 is sequentially passed through the second threading hole 120 and the second connecting tube 340, and the measuring rod is slidably passed through the bracket 100 and the second connecting tube 340 in turn.

[0070] like Figure 1 As shown, the second electrode assembly 300 also includes a second connecting tube 340 arranged on the bracket 100, the second connecting tube 340 is connected to the second threading hole 120, the second wire 330 is sequentially passed through the second threading hole 120 and the second connecting tube 340, and the measuring rod of the micrometer 310 is slidably passed through the bracket 100 and the second connecting tube 340, and the second connecting tube 340 can be used to further protect the measuring rod and the second wire 330, thereby extending the service life of the micrometer 310 and the second wire 330.

[0071] In some examples, the bracket 100 , the first connecting tube 220 , and the second connecting tube 340 are all made of organic glass material; the bracket 100 and the first connecting tube 220 are an integrated structure; and the bracket 100 and the second connecting tube 340 are an integrated structure.

[0072] By setting the support 100, the first connecting tube 220 and the second connecting tube 340 to be made of organic glass material, and setting the first connecting tube 220 and the second connecting tube 340 to be an integrated structure with the support 100, the weight of the support 100 can be relatively light while ensuring the structural reliability of the support 100, and the connection reliability between the first connecting tube 220 and the support 100 and the connection reliability between the second connecting tube 340 and the support 100 can be improved. In addition, the organic glass material has good transparency, which can also prevent the support 100 from blocking the observation line of the experimenter.

[0073] In some examples, isolation tube 400 is made of a plexiglass material.

[0074] By using the isolation tube 400 made of organic glass material, the good transparency of organic glass material can be utilized to facilitate the experimenter to observe the state of the sample 10' inside the isolation tube 400 during the test. In addition, organic glass material has good chemical stability and electrical insulation, which can prevent the isolation tube 400 from contaminating the sample 10' and improve the stability and reliability of the test process.

[0075] In some examples, both the cylinder block 500 and the cylinder head 600 are made of organic glass material.

[0076] By using the cylinder body 500 and the cylinder cover 600 made of organic glass material, the good transparency of the organic glass material can be used to facilitate the experimenter to observe the state of the sample 10' in the cylinder body 500. In addition, the organic glass material has high chemical stability and structural strength, which can prevent the cylinder body 500 and the cylinder cover 600 from contaminating the sample 10', provide further guarantee for the accuracy of the test results, and extend the service life of the cylinder body 500 and the cylinder cover 600.

[0077] According to the second aspect of the embodiment of the present application, an electrical testing system for unsaturated bentonite is proposed, including: a weighing device; an electrical testing device for unsaturated bentonite as proposed in any one of the first aspects above, wherein the bracket 100 is arranged on the weighing device; an impedance meter, wherein the first electrode assembly 200 and the second electrode assembly 300 are both connected to the impedance meter.

[0078] The electrical method test system of unsaturated bentonite provided in the embodiment of the present application includes a weighing device, an impedance meter and an electrical method test device of unsaturated bentonite as proposed in any one of the first aspects above, wherein the bracket 100 of the electrical method test device of unsaturated bentonite is arranged on the weighing device, so that the overall mass of the electrical method test device of unsaturated bentonite and other items arranged on the electrical method test device can be measured by the weighing device. The first electrode assembly 200 and the second electrode assembly 300 are both connected to the impedance meter, so that the electrical signal parameters of the sample 10' can be measured by the impedance meter.
