Description

Technical Field

[0001] This utility model belongs to the technical field of geological engineering testing devices, and in particular relates to a high-temperature and high-pressure triaxial testing device for rocks that can be connected in series and parallel. Background Technology

[0002] The high-temperature and high-pressure triaxial rock testing machine is mainly used to study water-rock permeability under high pressure and high temperature conditions. It can simulate the temperature and pressure conditions of geological formations and measure the liquid permeability of various rock samples. Through permeability testing, it can automatically collect data such as permeability, pH, dissolved oxygen, conductivity, and redox potential in the water.

[0003] In the process of viewing rocks from the side, the debris generated by rock fragmentation in the existing high temperature and high pressure triaxial rock testing machine can easily cause blockage of the recovery pipe, which in turn affects the smooth recovery of the recovery liquid. Manual cleaning is not only time-consuming and labor-intensive, but also affects the convenience of use.

[0004] To address these issues, we provide a high-temperature, high-pressure rock triaxial testing device that can be connected in series and parallel. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature and high-pressure triaxial rock testing device that can be connected in series and parallel. By controlling the reciprocating movement of the arc-shaped scraper, the scraper can clean the stone chips on the filter plate, thereby preventing the debris from adhering to the filter plate after rock testing and affecting the normal recovery of the recovery pipe. Furthermore, by controlling the clockwise rotation of the cylindrical tube, the rock after testing can be quickly dumped, thus improving the convenience of use. This invention solves the problem that in existing high-temperature and high-pressure triaxial rock testing machines, the debris generated by rock fragmentation during side viewing of the rock can easily cause blockage of the recovery pipe, thus affecting the smooth recovery of the recovery liquid. Manual cleaning is not only time-consuming and labor-intensive, but also affects the convenience of use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a high-temperature and high-pressure triaxial testing device for rocks that can be connected in series and parallel, including a shell assembly; the shell assembly includes a box, and a testing component is installed inside the box; the testing component includes a cylindrical tube, a recovery tube and a water inlet tube are fixedly inserted through the outer circumference of the cylindrical tube, a filter plate is installed at the end of the recovery tube, a sliding rod is slidably connected through the outer wall of the cylindrical tube, an arc-shaped scraper that slides in contact with the filter plate is fixedly connected near the end of the recovery tube on the sliding rod, a return spring sleeved on the sliding rod is fixedly connected between the arc-shaped scraper and the cylindrical tube, and a liquid storage box is fixedly connected between the recovery tube and the water inlet tube.

[0007] The present invention is further configured such that the housing assembly includes an arc-shaped pad block fixedly connected to the bottom of the housing body, the inner wall of the arc-shaped pad block is fixedly connected to an arc-shaped guide plate, and the inner wall of the arc-shaped guide plate is provided with an arc-shaped groove.

[0008] The present invention is further configured such that a path plate that abuts against the slide rod is fixedly connected to the inner wall of the arc-shaped guide plate, a collection box is fixedly connected to the bottom of the box body, and a hydraulic cylinder is fixedly connected to the top of the box body.

[0009] The present invention is further configured such that a circular plate located inside the housing and slidingly engaging with a cylindrical tube is fixedly connected to the output end of the hydraulic cylinder, three fixed rods are fixedly connected to the bottom of the circular plate off-center, a pressure plate is fixedly connected to the end of the fixed rods, and a pressure sensor is installed on the pressure plate.

[0010] The present invention is further configured such that a sealing door is hinged to one side of the housing, a control box is fixedly connected to an adjacent outer side of the housing, a brake motor is fixedly connected to an opposite outer side of the housing, and a rotating shaft extending into the interior of the housing is fixedly connected to the output end of the brake motor, and the rotating shaft is fixedly connected to a cylindrical tube.

[0011] The present invention is further configured such that the test assembly includes a support rod fixedly penetrating the bottom of the cylindrical tube, a support plate fixedly connected to the top of the support rod, a slider that slides in cooperation with the arc groove fixedly connected to the bottom of the support rod, a protective plate adapted to the filter plate fixedly connected to the top of the support plate, and a pressurizing device fixedly connected to the outer wall of the cylindrical tube.

[0013] This utility model has the following beneficial effects: 1. By controlling the cylindrical tube to rotate clockwise, this utility model drives the sliding rod and the arc-shaped scraper to rotate clockwise. During the clockwise rotation of the sliding rod, force is applied to the sliding rod towards the recovery pipe, causing the sliding rod and the arc-shaped scraper to move towards the recovery pipe, so that the arc-shaped scraper slides into contact with the filter plate. Then, without applying force to the sliding rod, the arc-shaped scraper is reset under the elastic force of the return spring. By controlling the reciprocating movement of the arc-shaped scraper, the arc-shaped scraper completes the cleaning of stone chips on the filter plate, thereby preventing the debris after rock testing from adhering to the filter plate and affecting the normal recovery of the recovery pipe. In addition, by controlling the clockwise rotation of the cylindrical tube, the rock after testing can be quickly dumped, thereby improving the convenience of use.

[0014] 2. This utility model places a rock inside a cylindrical tube, then controls a hydraulic cylinder to move a circular plate downwards, which in turn moves a pressure plate downwards, causing the pressure plate to squeeze the rock from different directions. A pressure sensor inside the pressure plate allows for precise control of the pressure exerted on the rock, thus improving the accuracy of the test. After the test, a brake motor is controlled to rotate the cylindrical tube clockwise, causing the cylindrical tube to rotate clockwise along an arc-shaped groove via a support rod. Simultaneously, the cylindrical tube causes a sliding rod to rotate along a path plate. The path plate, in conjunction with a return spring, provides power for the reciprocating movement of the sliding rod. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] For a specific implementation example, please refer to Implementation Example 1. Figure 1-6 This utility model is a high-temperature and high-pressure triaxial testing device for rocks that can be connected in series and parallel, including a shell assembly 1; the shell assembly 1 includes a box 101, and a test assembly 2 is installed inside the box 101; the test assembly 2 includes a cylindrical tube 201, a recovery tube 202 and a water inlet tube 203 are fixedly inserted through the outer periphery of the cylindrical tube 201, a filter plate 204 is installed at the end of the recovery tube 202, a slide rod 205 is slidably connected through the outer wall of the cylindrical tube 201, an arc-shaped scraper 206 that slides in contact with the filter plate 204 is fixedly connected near the end of the slide rod 205, a return spring 207 sleeved on the slide rod 205 is fixedly connected between the arc-shaped scraper 206 and the cylindrical tube 201, and a liquid storage box 208 is fixedly connected between the recovery tube 202 and the water inlet tube 203.

[0026] The operation process in this embodiment is as follows: Figure 1As shown, after the rock test is completed, the cylindrical tube 201 is rotated clockwise, which in turn drives the slide rod 205 and the arc-shaped scraper 206 to rotate clockwise. During the clockwise rotation of the slide rod 205, a force is applied to the slide rod 205 towards the recovery tube 202, causing the slide rod 205 and the arc-shaped scraper 206 to move towards the recovery tube 202 (at this time, the return spring 207 is stretched), so that the arc-shaped scraper 206 slides into contact with the filter plate 204. Then, no force is applied to the slide rod 205, and under the elastic force of the return spring 207, the arc-shaped scraper 206 returns to its original position. By controlling the reciprocating movement of the arc-shaped scraper 206, the arc-shaped scraper 206 completes the cleaning of stone chips on the filter plate 204, thereby preventing the debris after the rock test from adhering to the filter plate 204 and affecting the normal recovery of the recovery tube 202. In addition, by controlling the clockwise rotation of the cylindrical tube 201, the tested rocks can be quickly dumped, thereby improving the convenience of use.

[0027] For a specific embodiment two, please refer to Figure 1-6 Based on the specific embodiment 1, the housing assembly 1 further includes an arc-shaped pad 102 fixedly connected to the bottom of the box 101. An arc-shaped guide plate 103 is fixedly connected to the inner wall of the arc-shaped pad 102. An arc-shaped groove 104 is opened on the inner wall of the arc-shaped guide plate 103. A path plate 105 that abuts against the slide rod 205 is fixedly connected to the inner wall of the arc-shaped guide plate 103. A collection box 106 is fixedly connected to the bottom of the box 101. A hydraulic cylinder 107 is fixedly connected to the top of the box 101. A circular plate 108 located inside the box 101 and slidingly engaged with the cylindrical tube 201 is fixedly connected to the output end of the hydraulic cylinder 107. Three fixing rods 109 are fixedly connected to the bottom of the circular plate 108 off-center. A pressure plate 110 is fixedly connected to the end of the fixing rods 109. A pressure sensor is installed on the pressure plate 110. A sealing door 111 is hinged to one side of the box 101. An adjacent outer side of the box 101 is fixedly connected to the sealing door 111. A control box 112 is fixedly connected. A brake motor is fixedly connected to one of the outer sides of the housing 101. A rotating shaft 113 extending into the housing 101 is fixedly connected to the output end of the brake motor. The rotating shaft 113 is fixedly connected to the cylindrical tube 201. The test assembly 2 also includes a support rod 209 fixedly passing through the bottom of the cylindrical tube 201. A support plate 210 is fixedly connected to the top of the support rod 209. A slider 211 that slides with the arc groove 104 is fixedly connected to the bottom of the support rod 209. A protective plate 212 that matches the filter plate 204 is fixedly connected to the top of the support plate 210 (the protective plate 212 is set to prevent debris from breaking out during the rock test from damaging the recovery tube 202). A pressurizing device 213 is fixedly connected to the outer wall of the cylindrical tube 201. A PLC controller is installed inside the control box 112. The PLC controller is electrically connected to the brake motor, the pressurizing device 213, and the pressure sensor.

[0028] The operation process of this embodiment is as follows: The rock is placed inside the cylindrical tube 201. Then, the hydraulic cylinder 107 is controlled to drive the circular plate 108 to move downward, which in turn drives the pressure plate 110 to move downward, so that the pressure plate 110 squeezes the rock from different directions. Through the pressure sensor inside the pressure plate 110, the pressure of the pressure plate 110 on the rock can be precisely controlled, thereby improving the accuracy of the test. After the test is completed, the cylinder tube 201 is driven to rotate clockwise by controlling the brake motor, so that the cylinder tube 201 drives the slider 211 to rotate clockwise along the arc groove 104 through the support rod 209. At the same time, the cylinder tube 201 drives the slide rod 205 to rotate along the path plate 105 (the arc surface of the path plate 105 and the slide rod 205 in contact is wavy). Through the cooperation of the path plate 105 and the return spring 207, the reciprocating movement of the slide rod 205 is provided with power.
