[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] ReferenceFigures 1-6 This utility model provides an embodiment of a geomembrane hydrostatic pressure test sample fixing frame with a quick clamping mechanism, comprising: a test platform 1; a lower base 5 and an upper base 7, the lower base 5 being installed on the top of the test platform 1 and the upper base 7 being disposed on top of the lower base 5, the upper base 7 and the lower base 5 being used to fix the geomembrane; a mounting block 9, the mounting block 9 being fixedly connected to the top right side of the test platform 1; a motor 11, the motor 11 being disposed on the outer front side of the mounting block 9; a meshing gear 12 and a rack plate 13, the gear 12 being fixedly connected to the output end of the motor 11, and the rack plate 13 being slidably connected to the inside of the mounting block 9; and a connecting block 14, the connecting block 14 being fixedly connected to the outer left side of the rack plate 13, the top of the connecting block 14 being fixedly connected to... The upper base 7 is connected to the outside of the sample holder; and the moving component is used to move the sample holder. The mounting ring 10 is fixedly connected to the front side of the mounting block 9. The motor 11 is fixedly connected to the inside of the mounting ring 10. The mounting ring 10 is used to fix the motor 11. The lower base 7 has locking blocks 15 fixedly connected to both sides of the lower part. The lower base 5 has slots 6 on both sides of the inside. The locking blocks 15 and slots 6 engage with each other to improve the stability of the fixation. The lower base 5 has a water inlet 8 installed in the middle. The water inlet 8 is used to test the fixed geomembrane. The test platform 1 has a pressure boosting valve 2 installed on the front side of the outside of the pressure boosting valve 2. The pressure reducing valve 3 is installed on the right side of the outside of the pressure boosting valve 2. The pressure boosting valve 2 and the pressure reducing valve 3 are used to adjust the test pressure.

[0020] Specifically, in the process of fixing the geomembrane sample, the geomembrane sample to be tested is first laid flat on the upper part of the lower base 5. Then, the motor 11 is started. After the motor 11 starts, the gear 12 connected to its output end begins to rotate. The rotation of the gear 12 drives the rack plate 13 meshing with it to move downward. At the same time as the rack plate 13 moves downward, the connecting block 14 fixed to its outer side also moves downward synchronously. When the connecting block 14 moves downward, it further drives the upper base 7 fixed externally to press downward as a whole. As the upper base 7 continues to descend, it finally fits tightly with the lower base 5, completing the pressing and fixing of the geomembrane sample. The entire fixing process does not require manual intervention, is simple to operate, reduces the complexity and labor intensity of manual operation, saves sample fixing time, and improves the overall working efficiency and ease of use of the testing equipment.

[0021] Reference Figures 2-7The moving component includes an L-shaped plate 17, which is fixedly connected to the bottom left side of the test bench 1. A cylinder 16 is fixedly connected inside the L-shaped plate 17, and an inclined block 18 is fixedly connected to the output end of the cylinder 16. A slider 19 is fixedly connected to the top of the inclined block 18. A push rod 21 is slidably connected inside the L-shaped plate 17, and a pulley 22 is rotatably connected to the top of the push rod 21. A spring is sleeved on the outside of the push rod 21, and the pulley 22 contacts the inclined surface of the inclined block 18. A horizontal plate 23 is fixedly connected to the bottom of the push rod 21, and limit blocks 25 are fixedly connected to all four sides of the horizontal plate 23. A [missing information - likely a device or device] is installed around the bottom of the horizontal plate 23. The rollers 24 facilitate the movement of the device. Limiting grooves 26 are provided around the bottom of the test platform 1, and multiple limiting blocks 25 are slidably connected inside the multiple limiting grooves 26. The limiting grooves 26 facilitate the movement of the limiting blocks 25. A sliding groove 20 is provided at the bottom of the test platform 1, and a slider 19 is slidably connected inside the sliding groove 20. The sliding groove 20 facilitates the movement of the slider 19. A cabinet door 27 is installed on the left side of the test platform 1, and a handle is fixedly connected to the outside of the cabinet door 27. An operation panel 4 is installed on the upper part of the test platform 1 to facilitate the use of the operator.

[0022] Specifically, when it is necessary to move the geotextile sample hydrostatic testing device, firstly, cylinder 16 is started. After cylinder 16 is started, its output end drives the fixedly connected inclined block 18 to move laterally in the horizontal direction. When the inclined block 18 moves to one side and contacts the pulley 22, due to the inclined surface of the inclined block 18, the pulley 22 is squeezed under the contact pressure, thus producing a vertical downward displacement. Subsequently, the downward movement of the pulley 22 drives the top rod 21 connected to it to move downward synchronously, while squeezing the externally sleeved spring. When the top rod 21 moves downward, it pushes the horizontal plate 23 fixedly installed at its bottom downward as a whole. During the movement, the horizontal plate 23 drives the rollers 24 installed at its bottom to extend downward, so that the rollers... The roller 24 makes full contact with the ground and supports the weight of the entire test platform 1. At this time, the test platform 1 is lifted off the ground by the roller 24 and is in a movable state. Then, the cylinder 16 is closed and the cylinder 16 remains in its current position. The device is stably supported by the roller 24, and the test platform 1 can be manually pushed to move. When the device is moved to the required test position, the cylinder 16 is activated again, so that the horizontal plate 23 and the roller 24 are reset in sequence. After the roller 24 is completely retracted into the bottom of the test platform 1, the test platform 1 falls back to the ground. This realizes the easy movement of the geotextile sample static water test device. It can be moved to different locations at any time according to actual needs and adapt to different experimental environments, thereby improving the flexibility of the equipment.

[0023] Working principle: When fixing the geomembrane sample, firstly, the geomembrane sample is placed on the upper part of the lower base 5. Then, the motor 11 is started, which drives the gear 12 fixed at the output end to rotate. The rotation of the gear 12 drives the externally meshing rack plate 13 to move downward. When the rack plate 13 moves, it also drives the externally fixed connecting block 14 on the left side to move downward. When the connecting block 14 moves, it drives the upper base 7 to move downward, so that the upper base 7 and the lower base 5 are completely merged. This completes the fixing of the geomembrane sample. This means that when fixing the geomembrane sample, no manual fixing by the operator is required. The operation is simple, time-saving and labor-saving, thereby improving the testing efficiency of the equipment. When the device needs to be moved, firstly, cylinder 16 is activated. Cylinder 16 moves laterally along with the inclined block 18 fixed to the output belt. When the inclined block 18 contacts the pulley 22, the pulley 22 is squeezed and moves downward along with the top rod 21. As the top rod 21 moves downward, the bottom fixed horizontal plate 23 moves downward, and the horizontal plate 23 moves downward along with the rollers 24 installed around the bottom, so that the rollers 24 contact the ground and the top of the test platform 1 is reached. At this time, cylinder 16 is closed, and the test platform 1 is moved. After it is moved to the designated position, cylinder 16 is activated again to reset the rollers 24 so that the test platform 1 contacts the ground. This makes it easy to move the geotextile sample static water testing device. It can be moved to different locations at any time according to actual needs and adapt to different experimental environments, thereby improving the flexibility of the equipment.
