Description

Technical Field

[0001] This utility model relates to the field of materials mechanics testing, specifically to an intelligent saturation device for porous media materials. Background Technology

[0002] In fields such as geotechnical engineering and building materials, saturation treatment of test blocks is an important prerequisite for studying their performance. Existing saturation devices on the market often cannot precisely control the pressure and liquid injection volume when saturating samples, leading to uneven saturation and affecting the accuracy and reliability of experimental results. Furthermore, operators find it difficult to monitor the saturation state of the samples and changes in parameters such as water level and pressure within the device in real time, making it impossible to adjust the experimental process promptly. Utility Model Content

[0003] This invention aims to provide an intelligent saturation device for porous media materials, solving the problem of uneven saturation in existing saturation devices, improving the accuracy and reliability of experimental results, and reducing the workload of operators. The specific technical solution is as follows: A smart saturation device for porous media materials includes a barrel, a lid, and a controller. The barrel has an inlet, an outlet, an air extraction port, and an exhaust port. The inlet is connected to a water pump, the outlet is connected to a water tank, and the air extraction port is connected to a vacuum pump. Solenoid valves are installed at the inlet, outlet, air extraction port, and exhaust port. A pressure gauge is arranged on the upper side of the lid, and a jack driven by a servo motor is also arranged on the upper side of the lid. The movable end of the jack extends into the barrel. The controller is communicatively connected to each solenoid valve, water pump, vacuum pump, servo motor, and pressure gauge. During water injection, the controller controls the water pump to inject the required amount of water multiple times. After water injection and air extraction are completed, the jack extends to complete pressurization.

[0004] Furthermore, glass windows are installed on the side walls of the barrel, and cameras are installed on the outside of the glass windows.

[0005] Furthermore, a liquid level sensor is installed inside the tank, and the controller is connected to the liquid level sensor.

[0006] Furthermore, a stop is also provided on the upper side of the bucket lid to limit the maximum stroke of the jack.

[0007] Furthermore, a filter assembly is installed inside the water outlet.

[0008] The beneficial effects of this utility model are as follows: 1. By installing solenoid valves at the air inlet, exhaust outlet, water inlet, and water outlet, the amount of gas and liquid entering and exiting can be precisely controlled, thereby achieving precise control of the pressure and water level inside the tank. This ensures that the sample can absorb water evenly during the experiment, improving the uniformity of saturation and the accuracy of the experimental results.

[0009] 2. After the venting is completed, the pressure is increased by extending the jack, which can apply greater pressure to the water in the tank, causing more water to enter the sample and thus achieve a greater degree of saturation.

[0010] 3. The camera can monitor the changes in water level inside the tank in real time, allowing operators to intuitively understand the experimental process, identify problems in a timely manner, and make adjustments. Attached Figure Description

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0015] The present invention provides the following specific implementation scheme: like Figure 1As shown, this utility model provides an intelligent saturation device for porous media materials, including a barrel body, a barrel lid, and a controller. The barrel body is made of high-pressure resistant material, and the barrel body and the barrel lid are connected by snap-fit. The barrel body has an inlet, an outlet, a suction port, and an exhaust port. The inlet is connected to a water pump, the outlet is connected to a water tank, and the suction port is connected to a vacuum pump. Solenoid valves are installed at the inlet, outlet, suction port, and exhaust port. A pressure gauge is installed on the upper side of the barrel lid to detect the pressure inside the barrel. A jack driven by a servo motor is arranged on the upper side of the barrel lid, and the movable end of the jack extends into the barrel body. The controller is communicatively connected to each solenoid valve, water pump, vacuum pump, servo motor, and pressure gauge. During water injection, the controller controls the water pump to inject the required amount of water multiple times. After water injection and venting are completed, the jack extends to complete the pressurization.

[0016] Furthermore, the side wall of the barrel is equipped with a glass window, which is covered with an explosion-proof film, and a camera is installed on the outside of the glass window.

[0017] Furthermore, a liquid level sensor is installed inside the tank, and the controller is connected to the liquid level sensor.

[0018] Furthermore, a stop is also provided on the upper side of the bucket lid to limit the maximum stroke of the jack.

[0019] Furthermore, a filter assembly is installed inside the water outlet.

[0020] The saturation operation process is as follows: 1. Preparation stage: Place the sample to be saturated into the barrel, ensuring that the sample is placed stably, then lock the barrel lid to the barrel body, and then close all the solenoid valves on the barrel body.

[0021] 2. Vacuuming stage: The solenoid valve at the air extraction port opens, and the vacuum pump is started to evacuate the tank. During the evacuation process, the pressure inside the tank is monitored in real time. When the pressure reaches the preset value, the solenoid valve at the air extraction port closes, and the vacuum pump stops working.

[0022] 3. Water Injection Stage: Open the solenoid valve at the inlet. The controller operates the water pump, thereby controlling the flow rate and volume of water entering the high-pressure tank. According to experimental requirements, this embodiment involves three water injection operations: When the water submerges the sample to one-third of its height, close the solenoid valve at the inlet to stop water intake, allowing the sample to stand for 2 hours to allow water to fully penetrate the sample; then open the solenoid valve at the inlet and inject water to submerge the sample to two-thirds of its height, then stop water intake again and let it stand for 2 hours; subsequently, open the solenoid valve at the inlet until the water just submerges the sample, then stop water intake and let it stand for 2 hours; finally, inject water until the sample is submerged to a height of 10 cm or more, then stop water intake and let it stand for another 2 hours. Alternatively, the water can be replaced with other liquids, depending on the research needs. To achieve a higher saturation, it is recommended to use a degassing liquid, i.e., a liquid with low gas content after treatment. The specific number of water injections, water volume, and standing time can be adjusted according to experimental requirements.

[0023] 4. Pressurization stage: Open the solenoid valve at the vent. When the pressure inside the tank drops to 0, start the servo motor to extend the jack. At this time, observe the vent. When a uniform flow of water is coming out, close the solenoid valve at the vent and start applying servo pressure. The pressure and time of pressurization can be set and adjusted by the controller according to the specific research needs.

[0024] 5. Pressure Stabilization Stage: After pressurization, maintain stable pressure and environment inside the high-pressure tank and allow the sample to stand for 48 hours to allow it to fully saturate under stable pressure and humidity conditions. The specific standing time can be adjusted according to the test requirements.

[0025] 6. Pressure Relief and Drainage Stage: Open the solenoid valve at the vent to gradually reduce the air pressure inside the high-pressure tank to 0. Then, start the servo motor to retract the jack. Next, open the solenoid valve at the outlet, and the liquid inside the tank will automatically drain under gravity.

[0026] 7. Sample Removal Stage: After the liquid has been drained, open the lid and remove the saturated sample.

[0027] By installing solenoid valves at the air inlet, air outlet, water inlet, and water outlet, the flow of gas and liquid can be precisely controlled, thereby achieving precise control of the pressure and water level inside the tank. This ensures that the sample can absorb water evenly during the experiment, improving the uniformity of saturation and the accuracy of experimental results. After venting, pressurization is achieved by extending the jack, which can apply greater pressure to the water inside the tank, prompting more water to enter the sample and achieve greater saturation. The camera can monitor the changes in the water level inside the tank in real time, allowing operators to intuitively understand the experimental process, identify problems in a timely manner, and make adjustments.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
