Description

Technical Field

[0001] This invention relates to the field of porosity measurement technology, and in particular to a rotary multi-station core porosity measurement device. Background Technology

[0002] In the field of porosity measurement technology, accurate measurement of core porosity is of great significance to many fields such as geological exploration and oil and gas development.

[0003] Currently, most core porosity measuring devices on the market are single-station designs, which can only operate on a single core workpiece during the measurement process. After the measurement of a workpiece is completed, it is necessary to disassemble and replace it with a new workpiece before the measurement can continue, resulting in low measurement efficiency and making it difficult to meet the needs of batch core measurement.

[0004] Meanwhile, the alignment accuracy between the measuring components and the workpiece of the existing measuring device is not good. It often requires manual repeated adjustment of the workpiece position to ensure that the measuring components can accurately act on the workpiece. This not only increases the intensity of manual operation, but also easily affects the accuracy of the measurement results due to human operation errors.

[0005] In addition, most measuring devices lack an effective sealing structure, which can easily lead to problems such as liquid leakage and pressure loss during the measurement process, further reducing the reliability of porosity measurement data. Moreover, the measuring components lack flexibility and cannot flexibly adjust the measurement position and state according to different specifications of core workpieces, resulting in a narrow range of applications and difficulty in adapting to diverse measurement needs.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, through a rotary multi-station design, uses a rotating turntable to sequentially align multiple workpieces with the measuring component. Combined with a precisely fitted X-ray machine and temperature sensing ring, it significantly improves batch measurement efficiency and alignment accuracy, reducing human error. Furthermore, comparing two measurement data points during operation reduces data errors. Secondly, the double-sealed structure, along with pressure and temperature detection components, prevents liquid leakage and pressure loss, ensuring a stable measurement environment and improving data reliability. Additionally, the arc-shaped ring can accommodate workpieces of different specifications, and the measuring component's position can be flexibly adjusted via a servo motor and reciprocating screw, broadening its applicability. Simultaneously, components such as the heating chamber and filter enable liquid circulation, further optimizing measurement conditions. The overall structure is rationally designed and easy to operate, providing an efficient, accurate, and stable solution for core porosity measurement.

[0022] 2. This invention, by rotating a mounting turntable inside the liquid tank, and uniformly fixing multiple mounting plates in a circular array on the upper surface of the turntable, with symmetrical arc-shaped rings rotating on each mounting plate to fix the workpiece, and simultaneously using a first and a second measuring component, achieves multi-station synchronous measurement. The rotation of the mounting turntable can drive multiple workpieces to align sequentially with the measuring components, eliminating the need for frequent workpiece disassembly and replacement, significantly improving the measurement efficiency of batch core porosity. Furthermore, the X-ray machine is on the same horizontal line as adjacent workpieces, and the induction ring is slidably mounted on the outside of the arc-shaped ring, ensuring precise alignment between the measuring components and the workpieces, reducing manual adjustment operations, lowering human error, and improving the accuracy of measurement results. This solves the problems of low single-station measurement efficiency and poor alignment accuracy between measuring components and workpieces in existing devices.

[0023] 3. This invention, by fixing a first sealing plate to one end of the signal valve and having one end of the workpiece in contact with the outer surface of the first sealing plate, and cooperating with a second sealing plate at one end of the X-ray unit in the first measuring assembly in contact with the outer surface of the workpiece, forms a double sealing structure. This effectively avoids liquid leakage and pressure loss during measurement, ensuring the sealing of the measurement environment and thus improving the reliability of porosity measurement data. It solves the problems of poor sealing effect and insufficient reliability of measurement data in existing devices briefly mentioned in the background art.

[0024] 4. In this invention, the arc-shaped ring on the mounting plate achieves rotation adjustment and clamping operations through the cooperation of the second motor, drive gear, and pressure ring, which can adapt to core workpieces of different diameters, expanding the applicability of the device. At the same time, the first measuring component drives the first reciprocating screw through the first servo motor, which drives the X-ray machine and sensing ring to move flexibly. The second measuring component drives the second reciprocating screw through the second servo motor, which drives the collector and temperature sensing ring to adjust their positions, enabling the measuring components to flexibly adjust their working positions according to measurement requirements, further improving the accuracy and flexibility of measurement, and effectively solving the problems of narrow applicability and insufficient flexibility of measuring components in existing devices.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1 to 11 The present invention provides a technical solution:

[0045] A rotary multi-station core porosity measuring device includes a worktable 1. A battery 101 is fixedly installed inside the lower end of the worktable 1, providing power and connecting to external sources. A first motor 102 is fixedly installed inside the lower end of the worktable 1, and a first gear 103 is fixedly installed on the output shaft of the first motor 102. A second gear 104 is fixedly installed inside the lower end of the worktable 1, meshing with the first gear 103. The top of the second gear 104 extends to the upper surface of the worktable 1 and is fixedly mounted on a rotating disk 105. Figure 2 and Figure 3 As shown.

[0046] Therefore, during use, the first motor 102 drives the first gear 103 to rotate, and the meshing transmission between the first gear 103 and the second gear 104 enables the mounting turntable 105 to rotate. Furthermore, the upper surface of the mounting turntable 105 is precision-machined to ensure high flatness and concentricity, thus providing a reliable foundation for subsequent measurement operations.

[0047] A liquid tank 106 is fixedly mounted on the upper surface of the workbench 1. The liquid tank 106 has a hollow internal structure, and the upper surface in the middle is a through structure to the inside. The mounting turntable 105 is rotatably mounted inside the through hole. Figure 1 As shown.

[0048] A heating box 2 is installed inside the lower end of the workbench 1. A conveying pipe 201 is fixedly installed at the lower end of the heating box 2. The other end of the conveying pipe 201 is fixedly connected to the upper end of the liquid tank 106 and is in a through-flow state. A three-way pipe 202 is fixedly installed at the upper front end of the heating box 2. A filter 203 is slidably installed from the lower end of the three-way pipe 202 to its interior. Furthermore, a switch valve 204 is fixedly installed at the top of the three-way pipe 202. A connecting pipe 205 is fixedly installed at the top of the switch valve 204. The upper end of the connecting pipe 205 extends to the lower end of the liquid tank 106 and is fixedly connected to the lower end of the liquid tank 106. The two are in a through-flow state. Figure 2 As shown.

[0049] During use, the liquid being transported is heated by the heating chamber 2. After the heated solution reaches a suitable temperature, it is transported to the liquid tank 106 through the delivery pipe 201. After the operation is completed, the liquid inside the liquid tank 106 passes through the connecting pipe 205 and the switching valve 204. The switching valve 204 is automatically opened and closed by the signal transmission of the subsequent signal device 3. After opening, the liquid passes through the three-way pipe 202. The filter 203 inside the three-way pipe 202 filters the liquid, and then the liquid returns to the heating chamber 2 for reheating.

[0050] A signal device 3 is fixedly mounted on the center of the upper end face of the mounting turntable 105. A thermometer 301 is fixedly mounted on the top of the signal device 3. Four pressure gauges 302 are fixedly mounted in a ring array on the outer side of the signal device 3, and four pressure pumps 303 are fixedly mounted in a ring array on the outer side. The pressure pumps 303 and the pressure gauges 302 are electrically connected. Next, a first delivery pipe 304 is fixedly mounted on the lower end of each pressure pump 303. A signal valve 305 is fixedly mounted on the lower end of each first delivery pipe 304. One inner end of the signal valve 305 is fixedly mounted on the outer circumferential surface of the lower end of the signal device 3, and a first sealing plate 306 is fixedly mounted on the outer end of the signal valve 305.

[0051] A second delivery pipe 307 is fixedly installed on the lower end face of the signal valve 305. A water pump 308 is fixedly installed on the lower end of the second delivery pipe 307. The lower end of the water pump 308 is connected to a pipe that communicates with the liquid inside the liquid tank 106. Figure 4 As shown.

[0052] Therefore, during use, the signal device 3 will make adjustments between different devices and structures according to the actual measurement situation, while the temperature sensor 301 will display the temperature of the liquid inside the liquid tank 106 in real time.

[0053] Then, the pressure gauge 302 monitors the pressure changes of each pressure pump 303 and feeds the data back to the signal device 3 for precise control and adjustment. The signal valve 305 automatically opens or closes according to the received instructions, thereby controlling the pressure output of the pressure pump 303 and the liquid delivery of the water pump 308. The first sealing plate 306 ensures the subsequent sealing operation on the inside of the workpiece 7 to prevent liquid leakage from affecting the measurement accuracy.

[0054] It should be noted that the outer middle part of the first sealing plate 306 is open, which facilitates the pressure and liquid delivered by the pressure pump 303 and the water pump 308 to operate on the subsequent workpiece 7.

[0055] Throughout the process, the design of the first delivery pipe 304 and the second delivery pipe 307 ensures the stability and continuity of the operation transmission. In addition, the working state of the pressure pump 303 can be dynamically adjusted according to actual needs to adapt to the porosity measurement requirements of different core samples, which improves the automation level of the measuring device and also improves the reliability and efficiency of equipment operation. Through the coordinated work between the components, multi-station, high-precision measurement of core porosity can be achieved.

[0056] Four mounting plates 4 are evenly fixedly mounted in a circular array near the edge of the upper end face of the mounting turntable 105. Symmetrical mounting blocks 401 are fixedly mounted near the center of the upper end of the four mounting plates 4. An arc-shaped ring 402 is rotatably mounted on the outer side of each mounting block 401. It should be noted that in two adjacent arc-shaped rings 402, one arc-shaped ring 402 has U-shaped grooves on both sides of its opening, while the other arc-shaped ring 402 has its opening protruding outwards on both sides. These protruding structures can slide into the U-shaped grooves, making the two adjacent arc-shaped rings 402 fit more tightly together.

[0057] Then, a second motor 403 is fixedly installed on the inner side of the upper end of the mounting plate 4. The output shaft of the second motor 403 is fixedly connected to one of the adjacent arc-shaped rings 402. Drive gears 404 are fixedly installed on the lower outer sides of both adjacent arc-shaped rings 402, and the drive gears 404 mesh with each other. A pressure ring 405 is fixedly installed on the inner circumferential surface of the arc-shaped ring 402, and a pressure sensor 406 is fixedly installed on the outer circumferential surface. Figure 7 and Figure 8 As shown.

[0058] Therefore, during use, the core sample workpiece 7 is placed between the pressure rings 405 inside the arc ring 402, and one of the arc rings 402 is driven to rotate by the second motor 403. Due to the meshing action of the drive gear 404, the adjacent arc rings 402 will also move in tandem.

[0059] This design ensures that the pressure ring 405 applies uniform pressure to the core sample, while the pressure sensor 406 monitors the pressure value in real time to guarantee measurement accuracy. In addition, the tight fit between the arc-shaped rings 402 effectively avoids measurement errors caused by loosening or misalignment of the device, thereby improving the overall stability and reliability of the device. Moreover, since the first sealing plate 306 is located between two adjacent arc-shaped rings 402 and fits against the inner side of the workpiece 7, it achieves a seal on the inner side of the workpiece 7. It should be noted that the first sealing plate 306 can be designed to expand outward and contract inward depending on the situation, but both expansion and contraction structures need to be sealed to prevent leakage of liquid and internal pressure. However, the design needs to be tailored to the specific site conditions.

[0060] Then, a first measuring component 5 is fixedly installed on the front and rear edges of the upper end of the liquid tank 106, while a second measuring component 6 is fixedly installed on the left and right sides, as shown below. Figure 9 As shown.

[0061] The first measuring component 5 includes a first mounting rod 501. The lower end face of the first mounting rod 501 is fixedly mounted to the upper end face of the liquid tank 106. The first mounting rods 501 are arranged in pairs. The inner side and upper end face of each of the two adjacent first mounting rods 501 are provided with a first convex groove 502. A first servo motor 503 is fixedly mounted on the outer side of each first mounting rod 501. The output shaft of the first servo motor 503 extends into the interior of the first convex groove 502, and a first reciprocating screw 504 is fixedly mounted on the output shaft. Figure 10 As shown.

[0062] Secondly, a first triangular rod 505 is rotatably mounted on the circumferential surfaces of the two inner first reciprocating screws 504. An X-ray machine 506 is fixedly mounted on the upper inner surface of the first triangular rod 505. A first vacuum pump 507 is fixedly mounted on the upper end face of the X-ray machine 506. A second sealing plate 508 is fixedly mounted on one inner end of the X-ray machine 506, and a first delivery pump 509 is fixedly mounted on its lower end face. Furthermore, a first moving rod 510 is rotatably mounted on the circumferential surfaces of the two upper first reciprocating screws 504. An induction ring 511 is fixedly mounted on one inner end of the first moving rod 510. Figure 10 As shown.

[0063] During use, the first servo motor 503 is started first, which drives the first reciprocating screw 504 to rotate, thereby pushing the first triangular rod 505 and the first moving rod 510 to perform precise linear motion along the first convex groove 502.

[0064] By adjusting the position of the first triangular rod 505, the X-ray machine 506 can be aligned with the core sample to be tested, and the outer side of the workpiece 7 can be sealed by the second sealing plate 508. It should be noted that the second sealing plate 508 can also be the same as the first sealing plate 306, and the first vacuum pump 507 is used to evacuate the workpiece 7 to ensure that the air in the workpiece 7 is completely extracted, thereby providing accurate environmental conditions for subsequent porosity measurement.

[0065] The X-ray machine 506 is activated, and the X-rays emitted by the X-ray machine 506 can penetrate the core sample to be tested. The sensing ring 511 monitors the data of the X-ray machine 506 in real time and feeds the information back to the control system. The control system analyzes and processes the received data to determine the pore structure characteristics of the core sample. In this process, the high sensitivity design of the sensing ring 511 can capture subtle changes, thereby improving the accuracy of the measurement results. In addition, the sealing performance of the equipment and the vacuum environment further reduce the interference of external factors on the measurement, providing a guarantee for obtaining reliable porosity data.

[0066] The first delivery pump 509 is able to extract liquid from the workpiece 7 in conjunction with the pressure pump 303. However, the operation needs to be carried out according to the actual situation on site. Some parts need to be extracted, while others do not. The X-ray machine 506 can obtain the internal porosity data of the rock without the liquid, so it does not need to be used in conjunction with the liquid spray. However, some rocks do need to be extracted. Therefore, the operation needs to be carried out according to the actual situation.

[0067] Then, the second measuring component 6 includes a second mounting rod 601, the lower end face of the second mounting rod 601 is fixedly mounted on the upper end face of the liquid tank 106, and the second mounting rods 601 are arranged in pairs, with a second convex sliding groove 602 opened on the inner side and the upper end face, and a second servo motor 603 is fixedly mounted on one outer end, the output shaft extends into the interior of the adjacent second convex sliding groove 602, and a second reciprocating screw 604 is fixedly mounted on the output shaft.

[0068] A second triangular rod 605 is rotatably mounted on the circumferential surface of the two inner reciprocating screws 604. A collector 606 is fixedly mounted on the upper inner side of the second triangular rod 605. A second vacuum pump 607 is fixedly mounted on the upper end face of the collector 606, a second delivery pump 608 is fixedly mounted on the lower end, and a third sealing plate 609 is fixedly mounted on one inner end.

[0069] The second vacuum pump 607, the second delivery pump 608, and the third sealing plate 609 are fixedly connected by a pipe. The third sealing plate 609 has the same structure as the first sealing plate 306. Therefore, the second vacuum pump 607 and the second delivery pump 608 can operate on the subsequent workpiece 7. Then, a second moving rod 610 is threadedly mounted on the circumferential surface of the two second reciprocating screws 604 at the upper ends of the two adjacent second mounting rods 601. A temperature sensing ring 611 is fixedly mounted on one end of the inner side of the two adjacent second moving rods 610. Figure 11 As shown.

[0070] Therefore, during use, the second servo motor 603 is started, and the output shaft of the second servo motor 603 rotates the second reciprocating screw 604, causing the second triangular rod 605 to move the collector 606. The collector 606 moves synchronously with the second vacuum pump 607, the second delivery pump 608 and the third sealing plate 609. The third sealing plate 609 moves to fit inside the two adjacent arc-shaped rings 402 and the outer side of the workpiece 7 to achieve sealing.

[0071] Then, the second vacuum pump 607 performs a vacuuming operation. After completion, it works in conjunction with the water pump 308 and the second delivery pipe 307 to deliver water into the gap of the workpiece 7 inside the two arc-shaped rings 402.

[0072] During this process, the temperature sensing ring 611 monitors the temperature change in the sealed space in real time under the action of the second moving rod 610, and transmits the data to the control system. By observing the flow of the internal temperature liquid in the workpiece 7, the flow path of the internal pores in the workpiece 7 can be obtained in conjunction with the temperature sensing ring 611, thereby providing accurate data support for subsequent porosity analysis.

[0073] Meanwhile, the control system automatically adjusts the operating status of the second vacuum pump 607 and the second delivery pump 608 based on the information fed back by the temperature sensing ring 611, so as to ensure the stability of the environment within the sealed space.

[0074] After the measurement is completed, the second delivery pump 608 operates to extract the liquid inside the workpiece 7 into the liquid tank 106. In conjunction with the pressure pump 303, the liquid in the workpiece 7 can be completely extracted. Then, the above-mentioned X-ray irradiation is performed to obtain the model data after X-ray irradiation.
