DETAILED DESCRIPTION

[0060] The application will be further described in detail below with reference to the accompanying drawings and examples.

[0061] Example 1:

[0062] The example provides a portable core data comprehensive test box, which integrates a core making module and various test sensors for testing the core into a box body, is convenient to carry and store, and can effectively avoid damage, loss and other problems.

[0063] The comprehensive test box comprises a box body 1, a core making module, a test sensor assembly and an electrical processing unit. Figure 1 As shown in the figure, the core making module, the test assembly and the electrical processing unit are stored in the box body 1 when not in use; the box body 1 is divided into sections and arranged in multiple layers; by reasonable arrangement, the core making module, the test sensor assembly and the electrical processing unit are integrated and placed in the box body 1, so that the structure is compact and convenient to carry.

[0064] As an example: the box body 1 is a cuboid box made of aluminum alloy or other materials. The box body 1 is divided into two front and rear areas (which can be separated by a partition); the front area is further divided into two layers, the lower layer of the front area is arranged with electronic components of the electrical processing unit, and the upper layer is arranged with sensor units in the test sensor assembly; the left side of the rear area is used to place the core fixing support 4 in the test sensor assembly; the right side is divided into two layers, the lower layer is arranged with the core making module, and the upper layer is also used to arrange the sensor units in the test sensor assembly.

[0065] As an example, the box body 1 has a box cover 101 which can be opened and closed, and an operation display screen (touch display screen) is installed on the box cover 101.

[0066] The core making module is used to make a core sample with a flat cross section that meets the set requirements by polishing. As shown in the figure, Figures 8-10As shown, the core making module includes a micro motor 11, a connecting sleeve 12, an outer connecting shaft 2, and a grinding wheel 3. The micro motor 11 is arranged at the lower right layer of the rear side area of the box body 1, and a hole is opened at the position corresponding to the micro motor 11 on the right side wall of the box body 1, so that the motor shaft can be conveniently extended. The motor shaft is provided with the connecting sleeve 12, which is coaxially connected with the outer connecting shaft 2 (located outside the box body 1) for use. The outer connecting shaft 2 is provided with the grinding wheel 3. The outer end surface of the connecting sleeve 12 is located in the hole of the right side wall of the box body 1 and does not exceed the outer side surface of the right side wall of the box body 1. When the core making module is not in use, the outer connecting shaft 2 and the grinding wheel 3 are placed inside the box body 1, which is convenient for carrying. When in use, the outer connecting shaft 2 and the grinding wheel 3 are assembled, which are used for grinding the core and making the core sample with a flat and required cross section. That is, when the core making module is in use, the micro motor 11 drives the grinding wheel 3 to rotate, and the cross section of the core sample is ground to be flat and meet the requirements.

[0067] The test sensor assembly includes a core fixing support 4, an automatic detector, a fixed focal length camera 9, a hardness sensor 6, an automatic collection penetration instrument 7, a micro shear sensor 8, a density test sensor, and the like.

[0068] As shown in Figure 2 and Figure 3 , the core fixing support 4 includes a bottom plate 401, a top plate 402, and a plurality of elastic strips 404 arranged between the bottom plate 401 and the top plate 402. The bottom plate 401 and the top plate 402 are used as two clamping pieces to fix the core 14, and the elastic strips 404 provide tension for fixing the core 14. As an example, four elastic strips 404 are arranged in a rectangular shape between the bottom plate 401 and the top plate 402. The top plate 402 is provided with a hole 403 in the center, which is used to expose the cross section of the core sample 14, so as to facilitate accurate testing of the hardness, penetration, camera, and other sensors.

[0069] The automatic detector 5 is used for testing the wave speed of the core sample 14. As shown in Figure 4 , the automatic detector 5 includes a guide rail 503 and two probes arranged oppositely on the guide rail 503. The two probes are a first probe 501 and a second probe 502. The first probe 501 is fixed in position, and the second probe 502 is slidably connected with the guide rail 503 through a sliding base, so as to slide relative to the first probe 501 on the guide rail 503 to adapt to cores of different lengths and sizes. The sliding base of the second probe 502 is connected with a displacement sensor A, and the displacement is 0 (i.e., the origin position) when the first probe 501 and the second probe 502 are in close contact. Figure 11As shown, during the wave velocity test, the second probe 502 is slid away from the first probe 501, and one end of the core sample 14 is placed against the first probe 501, and then the second probe 502 is slid to be close to the other end of the core sample, and the displacement sensor A can automatically read the displacement data of the second probe 502 at this time, which is the length of the core sample 14. The displacement sensor A is electrically connected with the electrical processing unit, and the length of the core sample 14 detected is sent to the electrical processing unit. At the same time, the time length of the wave received by the core sample 14 is tested by the two probes, and the principle is that the first probe 501 emits a sound wave with a frequency of f (period T), and the second probe 502 receives the wave. The sound wave travels from the probe 501, passes through the core sample 14, and reaches the probe 502. The electrical processing unit records the emission time t1 and the receiving time t2, and then calculates the propagation time Δt = t2-t1. Knowing the length L of the core, the electrical processing unit finally calculates the wave velocity V = L / Δt.

[0070] As an example, further, as Figure 4 As shown, vertical strip grooves are arranged on the mounting seats of the first probe 501 and the second probe 502, and the fasteners for fastening the first probe 501 and the second probe 502 can move up and down in the strip grooves to adjust the positions of the first probe 501 and the second probe 502 in height, thereby adapting to core samples 14 with different diameters.

[0071] The fixed-focus camera 9 is fixed on the camera support 10, which is a circular table as an example, and the fixed-focus camera 9 is fixed on the upper end face of the camera support 10. A crosshair is arranged on the lens of the fixed-focus camera 9, and Figure 6 As shown, the scale value of the crosshair matches the length of the camera support 10. As shown, Figure 12 As shown, during the test, the core sample 14 is fixed on the core fixing support 4, the lower end of the camera support 10 is attached to the outer edge of the hole 403 on the top plate 402 of the core fixing support 4, and the fixed-focus camera 9 is directed to the core sample 14 for shooting, so that a core section photo with uniform focal length and distance can be formed, which is convenient for comparative analysis. The fixed-focus camera 9 is electrically connected with the electrical processing unit, and the core section photo shot is sent to the electrical processing unit.

[0072] As shown, Figure 13 As shown, during the hardness test, the core sample 14 is fixed on the core fixing support 4, and then the hardness sensor 6 directly tests the hardness data of the core sample 14 by the section of the core sample 14 leaking through the hole 403; the hardness sensor 6 is electrically connected with the electrical processing unit, and the test data is sent to the electrical processing unit.

[0073] As shown, Figure 5As shown, the automatic acquisition penetrometer is a structure provided with a displacement sensor B702 at the tail of the penetration test sensor (the traditional penetration test sensor uses a scale line on the sensor structure for manual reading of the penetration depth value) ; the displacement sensor B702 is connected to the rear end of the penetration needle in the penetration test sensor, and the displacement sensor B702 moves with the penetration needle during the penetration test to measure the displacement. Figure 14 As shown, during the penetration test, the core sample 14 is fixed on the core fixing support 4; the penetration needle of the automatic acquisition penetrometer directly vertically penetrates the cross section of the core sample 14 leaked out of the hole 403 under the action of hammering; the displacement sensor B702 is electrically connected with the electrical processing unit to send the test data to the electrical processing unit, thereby realizing automatic reading of the penetration depth value. The electrical processing unit automatically converts into the penetration test result: N = 30n / Δs; in the formula: Δs is the actual penetration depth (unit: cm, which is the measured value of the displacement sensor B702) ; n is the number of hammering (times) for penetrating Δs depth.

[0074] The miniature shear sensor 8 tests the shear strength value of the core by being inserted into the core sample 14; as shown, Figure 15 As shown, during the test, the core sample 14 is fixed on the core fixing support 4, and then the miniature shear sensor 8 is inserted into the core sample 14 through the hole 403 for testing. The miniature shear sensor 8 is electrically connected with the electrical processing unit to send the test data to the electrical processing unit.

[0075] The density test assembly uses a tension sensor 13, and its test principle is as follows: first, the tension sensor 13 is used to measure the weight of the core sample 14 in the air, at which time the tension value G1 displayed by the tension sensor 13 is the gravity suffered by the core sample 14. Then the core sample 14 is immersed in water, and is measured again. At this time, the core sample 14 suffers not only its own gravity (downward) but also the buoyancy of water (upward). Therefore, the tension value G2 displayed by the tension sensor 13 is the difference between the gravity and the buoyancy of the core sample 14. The electrical processing unit calculates the volume of the core sample 14 by using the weight difference (i.e. the size of the buoyancy) of the obtained tension values G1 and G2, and then automatically calculates the density of the core sample 14. Specifically,

[0076] G1 = ρ 芯 V 芯 ·g;

[0077] Wherein: G1 is the value displayed by the tension sensor 13 when the core sample 14 is measured in the air; ρ 芯 is the density of the core sample 14 to be solved; V 芯 is the volume of the core sample 14; g is the acceleration of gravity;

[0078] G2 = ρ芯 V 芯 ·g-ρ 水 V 芯 ·g;

[0079] Wherein: G1 is the value displayed by tension sensor 13 when core sample 14 is completely immersed in water; ρ 水 is the density of water;

[0080] The above two formulas are subtracted to obtain: V 芯 = (G1-G2) / ρ 水 g;

[0081] Thus: ρ 芯 =G1·ρ 水 / (G1-G2)

[0082] Thus, as long as G1 and G2 are measured and the density of water ρ 水 is known, the density of core sample 14 can be directly calculated.

[0083] As Figure 13 shown, when the relative density of the core is tested, core sample 14 is taken off from core fixing support 4, packed with a net bag, and hung below tension sensor 13. The tension values of tension sensor 13 in air and water are read respectively, and the electrical processing unit can automatically calculate the density and save according to the read tension values.

[0084] As Figure 7 shown, the electrical processing unit is pre-set with a processing program, and each sensor and touch display screen is electrically connected with the electrical processing unit. The electrical processing unit is powered by a battery, can process and store the data tested by the sensor, and display on the operation display screen. At the same time, the electrical processing unit has GPS positioning function and remote transmission function, can read the position of the core test, i.e. the test position of the data test box, ensures that the core sample comes from the real geological exploration address, and avoids fraud. The remote transmission function can upload and send the data results and photos of the core test to the remote end.
