[0002] In rock mechanics experiments, it is often necessary to analyze the effect of rock water content on the mechanical properties of rock masses, which requires saturating rock samples with water. However, due to the varying shapes and sizes of rock samples, existing saturation devices are difficult to apply to rock samples of different shapes and sizes, resulting in poor saturation effects. Utility Model Content

[0004] To achieve the above objectives, the present invention proposes a water-saturation device for rock samples, the water-saturation device comprising:

[0005] A flexible water-saturated cover has a sealed water-saturated cavity inside, which is used to contain the rock sample. The flexible water-saturated cover can be flexibly deformed to match the shape of the water-saturated cavity with that of the rock sample.

[0006] A water supply assembly, comprising a water supply pipe and a water storage structure, wherein the two ends of the water supply pipe are respectively connected to the water-saturated cavity and the water storage structure, and the water storage structure is used to store water;

[0007] A pressurization assembly, comprising a pressurization pipe, a vacuum pump, and a pressurization tank, wherein the vacuum pump is connected to the pressurization tank, and both ends of the pressurization pipe are connected to the saturated chamber and the pressurization tank, respectively.

[0008] In one embodiment, the water storage structure includes a water storage tank, a water storage cavity is formed inside the water storage tank, one end of the water supply pipe away from the flexible water-filled cover extends into the water storage cavity and extends to the bottom of the water storage cavity, the water storage cavity being used to store water.

[0009] In one embodiment, a water supply hole is formed on the top of the water storage tank, the water supply hole is connected to the water storage cavity, the shape of the water supply hole matches and is sealed to the water supply pipe, and the water supply pipe can movably pass through the water supply hole and extend into the water storage cavity.

[0010] In one embodiment, a first sealing ring is provided at the water supply hole, and a second sealing ring is provided on the outer sleeve of the water supply pipe, with the first sealing ring and the second sealing ring sealingly fitted together.

[0011] In one embodiment, an external threaded section is formed on the outside of the water supply pipe, and an internal threaded section is formed inside the water supply hole, wherein the internal threaded section and the external threaded section are threadedly engaged.

[0012] In one embodiment, both the water supply pipe and the pressurization pipe are equipped with valves.

[0017] The technical solution of this utility model involves placing a rock sample within a saturation chamber of a flexible saturation hood. When saturation is required, an air pump draws air from a pressure tank, creating a negative pressure that also creates a negative pressure in the saturation chamber connected to the pressure tank via a pressure pipe. This negative pressure allows water stored in a water storage structure to be drawn into the saturation chamber through a water supply pipe, thus saturating the rock sample. Furthermore, the flexible saturation hood is flexible and deformable. Under negative pressure, the hood can deform to fit snugly against the rock sample within the chamber. This close contact with the sample further forces water into the rock sample, making the solution suitable for rock samples of different shapes and sizes and improving the saturation effect.

[0027] In rock mechanics experiments, it is often necessary to analyze the effect of rock water content on the mechanical properties of rock masses, which requires saturating rock samples with water. However, due to the varying shapes and sizes of rock samples, existing saturation devices are difficult to apply to rock samples of different shapes and sizes, resulting in poor saturation effects.

[0028] This utility model proposes a water saturation device 100 for rock samples.

[0029] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the water saturation device 100 for the rock sample includes a flexible water saturation cover 10, a water supply component 20, and a pressurization component 30. A sealed water saturation cavity 11 is formed inside the flexible water saturation cover 10, which is used to contain the rock sample. The flexible water saturation cover 10 can be flexibly deformed so that the water saturation cavity 11 matches the shape of the rock sample. The water supply component 20 includes a water supply pipe 22 and a water storage structure 21. The two ends of the water supply pipe 22 are respectively connected to the water saturation cavity 11 and the water storage structure 21, and the water storage structure 21 is used to store water. The pressurization component 30 includes a pressurization pipe 31, a vacuum pump 32, and a pressurization tank 33. The vacuum pump 32 is connected to the pressurization tank 33, and the two ends of the pressurization pipe 31 are respectively connected to the water saturation cavity 11 and the pressurization tank 33.

[0030] The technical solution of this utility model involves placing a rock sample in a saturated cavity 11 within a flexible saturated cover 10. When it is necessary to saturate the rock sample, an air pump 32 is used to pump air into a pressure tank 33. After the pressure tank 33 is pumped out, it will form a negative pressure, which will also form a negative pressure in the saturated cavity 11 connected to the pressure tank 33 through a pressure pipe 31. The negative pressure in the saturated cavity 11 can draw water stored in the water storage structure 21 into the saturated cavity 11 through a water supply pipe 22, so as to saturate the rock sample contained in the saturated cavity 11. Furthermore, since the flexible water-saturated cover 10 can undergo flexible deformation, it can deform under negative pressure in the water-saturated cavity 11, so that the flexible water-saturated cover 10 can fit tightly against the rock sample inside the water-saturated cavity 11. The flexible water-saturated cover 10, which is tightly fitted against the rock sample inside, can further press the water inside into the rock sample, thus making it applicable to rock samples of different shapes and sizes, and further improving the effect of water saturation treatment on rock samples.

[0031] In one embodiment of the present invention, the water storage structure 21 includes a water storage tank 211, a water storage cavity 2111 is formed inside the water storage tank, and the end of the water supply pipe 22 away from the flexible water-filled cover 10 extends into the water storage cavity 2111 and extends to the bottom of the water storage cavity 2111. The water storage cavity 2111 is used to store water.

[0032] Specifically, such as Figure 2 As shown, a water storage chamber 2111 is formed inside the storage tank. The water storage chamber 2111 is used to store water. The end of the water supply pipe 22 away from the flexible saturation cover 10 extends into the water storage chamber 2111. When the saturation chamber 11 is under negative pressure, water in the water storage chamber 2111 can be drawn into the saturation chamber 11 through the water supply pipe 22 extending into the water storage chamber 2111. The structure is simple. Furthermore, the end of the water supply pipe 22 extending into the water storage chamber 2111 extends to the bottom of the saturation chamber 11. The water supply pipe 22 extending to the bottom can better draw water from the water storage chamber 2111 into the saturation chamber 11.

[0033] In one embodiment of the present invention, a water supply hole 2112 is formed on the top of the water storage tank 211. The water supply hole 2112 is connected to the water storage cavity 2111. The shape of the water supply hole 2112 matches and is sealed with the water supply pipe 22. The water supply pipe 22 can movably pass through the water supply hole 2112 and extend into the water storage cavity 2111.

[0034] Specifically, such as Figure 2 As shown, the top of the water storage tank 211 has a water supply hole 2112. The water supply pipe 22 passes through the water supply hole 2112 and extends into the water storage chamber 2111, thus communicating with the water storage chamber 2111. Furthermore, since the water supply pipe 22 can move relative to the water supply hole 2112, when water needs to be added to the water storage chamber 2111, the water supply pipe 22 can be pulled out from the water supply hole 2112, and water can then be added to the water storage chamber 2111 through the water supply hole 2112, which is simple and convenient. Because the water supply pipe 22 and the water supply hole 2112 are matched in shape and have a sealed fit, a relatively stable negative pressure can be formed in the saturated chamber 11, the water supply pipe 22, and the water storage chamber 2111, thereby reliably drawing water from the water storage chamber 2111 into the saturated chamber 11, resulting in higher reliability.

[0035] In one embodiment of this utility model, a first sealing ring 2113 is provided at the water supply hole 2112, and a second sealing ring 221 is provided on the outer sleeve of the water supply pipe 22, with the first sealing ring 2113 and the second sealing ring 221 sealingly engaged.

[0036] Furthermore, such as Figure 2 As shown, a first sealing ring 2113 is provided at the water supply hole 2112, and a second sealing ring 221 is provided on the outer sleeve of the water supply pipe 22. After one end of the water supply pipe 22 extends into the water storage cavity 2111, the first sealing ring 2113 and the second sealing ring 221 seal and cooperate, which can more effectively ensure the sealing reliability of the connection between the water supply pipe 22 and the water storage cavity 2111.

[0037] In one embodiment of this utility model, an external thread section is formed on the outside of the water supply pipe 22, and an internal thread section is formed inside the water supply hole 2112, with the internal thread section and the external thread section threadedly engaged.

[0038] Specifically, the water supply pipe 22 can be quickly installed into the water storage tank 211 through the threaded engagement between the external threaded section outside the water supply pipe 22 and the external threaded section inside the water supply hole 2112, making installation simple and convenient. Furthermore, the threaded engagement between the internal and external threaded sections can further improve the sealing effect at the water supply hole 2112, resulting in better sealing performance.

[0039] In one embodiment of this utility model, valves 40 are provided on both the water supply pipe 22 and the pressurization pipe 31. After water is drawn from the water storage structure 21 into the saturated chamber 11 through the water supply pipe 22, closing the valves 40 on the water supply pipe 22 and the pressurization pipe 31 ensures that the water drawn into the saturated chamber 11 remains within the saturated chamber 11 and that the saturated chamber 11 is always under negative pressure, thereby further improving the effect of saturation treatment on the rock sample in the saturated chamber 11.

[0040] In one embodiment of this utility model, both the water supply pipe 22 and the pressurizing pipe 31 are rigid pipes. After the air pump 32 evacuates the pressurizing tank 33 to create a negative pressure, since both the water supply pipe 22 and the pressurizing pipe 31 are rigid pipes, they can withstand a certain negative pressure to prevent deformation. This effectively ensures the connection between the pressurizing tank 33 and the saturated chamber 11, as well as the connection between the water storage structure 21 and the saturated chamber 11, resulting in higher reliability.

[0041] In one embodiment of this utility model, a pressure gauge is provided on the pressure tank 33, and the pressure gauge is used to monitor the pressure inside the pressure tank 33.

[0042] Specifically, a pressure gauge is installed on the pressure tank 33. The pressure gauge can monitor the pressure inside the pressure tank 33, thereby monitoring the pressure in the saturated chamber 11 connected to the pressure pipe 31. This allows for more precise control of the pressure inside the saturated chamber 11, thus improving the effectiveness of saturation treatment of the rock sample inside the saturated chamber 11.

[0043] In one embodiment of the present invention, the air pump 32 is connected to the top of the pressure tank 33, and the end of the pressure pipe 31 near the pressure tank 33 is connected to the bottom of the pressure tank 33.

[0044] Specifically, such as Figure 1 As shown, when the vacuum pump 32 is working, the pressure tank 33 is under negative pressure. The pressure pipe 31 will draw water from the saturated chamber 11 into the pressure tank 33. Connecting the vacuum pump 32 to the top of the pressure tank 33 and the pressure pipe 31 to the bottom of the pressure tank 33 effectively prevents the vacuum pump 32 from drawing water from the pressure tank 33 into itself.

[0045] In one embodiment of this utility model, the flexible water-saturated cover 10 is a rubber water-saturated cover. The rubber water-saturated cover has good deformability, and using it as the flexible water-saturated cover 10 can meet the deformation requirements of the flexible water-saturated cover 10. When the water-saturated cavity 11 is under negative pressure, due to the good deformability of the rubber water-saturated cover, it can deform and fit well against the rock sample inside, thereby better squeezing the water from the water-saturated cavity 11 into the rock sample, resulting in a better water-saturation treatment effect on the rock sample.

[0046] In one embodiment of this utility model, the water storage tank 211 is a transparent water storage tank 211, and a scale is provided on the tank wall of the transparent water storage tank 211. Specifically, by using the transparent water storage tank 211 to store water, it is relatively convenient to observe the water stored in the transparent water storage tank 211, and the volume of water stored in the transparent water storage tank 211 can be obtained more conveniently and quickly through the scale on the tank wall. After the rock sample has been saturated with water, the change in the volume of water stored inside the water storage tank 211 can be easily measured, thereby obtaining the amount of water absorbed by the rock sample, and thus the water absorption rate of the rock sample can be calculated relatively easily and intuitively.

[0047] In one embodiment of the present invention, the end of the water supply pipe 22 near the flexible water-filled cover 10 and the end of the pressurizing pipe 31 near the flexible water-filled cover 10 are respectively connected to the narrow openings of the two funnels 50, and the flared openings of each funnel 50 are connected to the flexible water-filled cover 10.

[0048] Specifically, such as Figure 1 As shown, both the pressurizing pipe 31 and the water supply pipe 22 are connected to the flexible water-filled cover 10 via funnels 50. Both the pressurizing pipe 31 and the water supply pipe 22 are connected to the narrow opening of the funnels 50, while the flared opening of each funnel 50 is connected to the flexible water-filled cover 10. The funnels 50 connected to the pressurizing pipe 31 can better draw gas from the water-filled chamber 11, thus better maintaining a negative pressure in the water-filled chamber 11. The funnels 50 connected to the water supply pipe 22 can better draw water from the water storage structure 21 into the water-filled chamber 11 even when it is under negative pressure, resulting in a better suction effect.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
