[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The rock mass reaction testing device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1 As shown, a rock reaction test device 100 according to an embodiment of the present invention comprises: a flexible container 1, a first pipeline, a pressure container 2 and a confining pressure piece 3, wherein the flexible container 1 comprises a first box body and a first cover body, the first box body defines a reaction space 11 and one end of the first box body is openly arranged, the reaction space 11 can accommodate a test rock mass 4, the first cover body can close the open end of the first box body to seal the reaction space 11, the first pipeline is connected to the reaction space 11, the reaction fluid can flow into the reaction space 11 through the first pipeline to react with the test rock mass 4 and generate hydrogen, the pressure container 2 defines a receiving space, the flexible container 1 is arranged in the receiving space, the confining pressure piece 3 is arranged in the receiving space and is located between the flexible container 1 and the pressure container 2, and the confining pressure piece 3 is used to apply confining pressure to the flexible container 1.

[0025] The reactants of the rock reaction include the test rock 4. In the rock reaction, the test rock 4 can be placed in the reaction space 11 defined by the first box of the flexible container 1. The first box has an open end. The test rock 4 can be placed in the reaction space 11 through the open end. The first cover can cover the open end of the first box to form a closed space in the flexible container 1, which is conducive to the rock reaction and can reduce the risk of leakage of hydrogen generated by the rock reaction. The flexible container 1 can be deformed when under pressure, and then the flexible container 1 can fit the test rock 4 tightly to apply confining pressure to the test rock 4.

[0026] The first pipeline of the rock reaction test device 100 can be connected to the reaction space 11 . The first pipeline can be used to transport the reaction fluid into the reaction space 11 . The reaction fluid and the test rock mass 4 can chemically react in the reaction space 11 to generate hydrogen.

[0027] The pressure container 2 of the rock reaction test device 100 has certain structural strength and rigidity, and the pressure container 2 is not easy to deform. The pressure container 2 can define a receiving space, and the flexible container 1 and the confining pressure piece 3 can be placed in the receiving space. The confining pressure piece 3 can be located between the flexible container 1 and the pressure container 2. The volume of the confining pressure piece 3 can be changed. By increasing the volume of the confining pressure piece 3, the confining pressure piece 3 can squeeze the flexible container 1 so that the flexible container 1 can fit closely to the test rock mass 4. As some embodiments of the present application, the pressure container 2 can be constructed as a metal container. By constructing the pressure container 2 as a metal container, the pressure of the confining pressure piece 3 is not easy to deform the pressure container 2, or the pressure container 2 will undergo a slight deformation when subjected to the pressure of the confining pressure piece 3, so that the confining pressure piece 3 can expand almost completely toward the flexible container 1, so that the confining pressure can be applied to the flexible container 1 more accurately.

[0028] In the above embodiment, by placing the flexible container 1 containing the test rock mass 4 in the containing space of the pressure container 2 and applying confining pressure to the flexible container 1 with the confining pressure member 3, the test rock mass 4 can react and generate hydrogen, and the rock reaction test device 100 can have good sealing properties, which can not only enable the rock reaction to proceed smoothly, but also reduce the risk of leakage of hydrogen generated by the reaction, thereby improving the accuracy of the rock reaction results and reducing the danger of the experiment.

[0029] In some embodiments of the present invention, the flexible container 1 is made of rubber, and the first cover and the first box are sealed by rubber.

[0030] Among them, the flexible container 1 can be made of rubber, which has good elasticity, good wear resistance, good chemical stability, and good heat resistance. The flexible container 1 made of rubber is not easily corroded by the reactants or products in the rock reaction and fails, thereby extending the service life of the rock reaction test device 100.

[0031] It can be understood that rubber will not participate in the rock mass reaction and therefore will not affect the test results, thus ensuring the accuracy of the test results.

[0032] The first cover and the first box can be sealed by rubber, and rubber adhesive can be applied at the connection between the first cover and the first box to seal the flexible container 1, so that the entire flexible container 1 can be made of rubber, which is conducive to ensuring the accuracy of the experimental results. In addition, the rubber can quickly return to its original shape after deformation, so that the flexible container 1 made of rubber can be reused.

[0033] In some embodiments of the present invention, the flexible container 1 is made of fluororubber, and the first cover and the first box are sealed by fluororubber.

[0034] Among them, the flexible container 1 can be made of fluororubber, which is resistant to high temperature, oil, oxidation, heat, chemical corrosion, and atmospheric aging. It has certain solvent resistance and good stability, so that the flexible container 1 made of fluororubber can be used for a long time without failure. The flexible container 1 is not easily corroded by the reactants or products in the rock reaction, which can further extend the service life of the rock reaction test device 100.

[0035] It is understandable that fluororubber will not participate in the rock mass reaction and therefore will not affect the test results, ensuring that the test results are more accurate.

[0036] The first cover body and the first box body can be sealed by fluororubber, and fluororubber adhesive can be applied at the connection between the first cover body and the first box body to seal the flexible container 1, so that the entire flexible container 1 can be made of fluororubber, which is conducive to ensuring the accuracy of the experimental results.

For example, if only the reaction gas is needed in this experiment, the reaction gas may flow into the reaction space 11 through the first sub-pipeline, if only the reaction liquid is needed in this experiment, the reaction liquid may flow into the reaction space 11 through the second sub-pipeline, if both the reaction gas and the reaction liquid are needed in this experiment, the reaction gas may flow into the reaction space 11 through the first sub-pipeline, and the reaction liquid may flow into the reaction space 11 through the second sub-pipeline.

[0039] The reaction gas and the reaction liquid can react with the test rock 4 in the reaction space 11. By setting the first sub-pipeline and the second sub-pipeline, an appropriate amount of reaction gas and / or reaction liquid can be transported into the reaction space 11 according to experimental requirements, so that the rock reaction test device 100 proposed in the present application can meet various experimental needs. In addition, by allowing the reaction gas and the reaction liquid to flow into the reaction space 11 through different pipelines, the risk of mutual contamination between the reaction gas and the reaction liquid can be reduced.

[0040] As some embodiments of the present application, the test rock mass 4 can be perforated, or the test rock mass 4 itself can have cracks, so that the reaction gas and the reaction liquid can enter the test rock mass 4 to increase the contact area between the reactants, thereby accelerating the reaction rate and improving the degree of reaction.

[0041] As some embodiments of the present application, the flexible container 1 and the pressure container 2 may have corresponding first mounting holes and corresponding second mounting holes, the first sub-pipeline may be passed through the first mounting holes of the flexible container 1 and the pressure container 2, and the second sub-pipeline may be passed through the second mounting holes of the flexible container 1 and the pressure container 2, so that the reaction gas and the reaction liquid may flow into the reaction space 11 through the first sub-pipeline and the second sub-pipeline, respectively.

This arrangement enables the rock reaction test device 100 to apply confining pressure to test rock masses 4 of different shapes, so that the rock reaction proceeds smoothly.

[0044] As some embodiments of the present application, there may be four confining pressure pieces 3, which are respectively arranged on the left side, right side, front side and rear side of the flexible container 1; or, there may be six confining pressure pieces 3, which are respectively arranged on the upper side, lower side, left side, right side, front side and rear side of the flexible container 1, so as to apply confining pressure to various directions of the flexible container 1, thereby enabling the flexible container 1 to fit tightly against the test rock mass 4, so as to apply confining pressure to the test rock mass 4.

[0046] Among them, the second pipeline of the rock reaction test device 100 can be used to connect the pressure medium storage container and the pressure pillow. The pressure medium (for example but not limited to hydraulic oil) can be stored in the pressure medium storage container. The pressure medium can flow from the pressure medium storage container into the pressure pillow through the second pipeline to expand the pressure pillow. The expanded pressure pillow can apply confining pressure to the test rock 4 in the flexible container 1 to ensure smooth rock reaction.
