The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1:

[0024] Please see Figures 1-4 As shown, this utility model provides a concrete material impermeability testing device, including a testing platform 1. A pressure seat 9 is fixedly connected to the middle of the top of the outer surface of the testing platform 1. A test mold 10 is placed on the top of the pressure seat 9. Fixed plates 5 are fixedly connected to both ends of the top of the outer surface of the testing platform 1. A bidirectional screw 4 is movably connected between the two ends of the two fixed plates 5 through bearings. A movable plate 3 is threaded to both ends of the bidirectional screw 4. An arc-shaped limiting frame 7 is fixedly connected to the surface of the movable plate 3. A water tank 14 is fixedly connected to the bottom of the inner cavity of the testing platform 1. A pressure pump 15 is fixedly installed on the right side of the water tank 14 through a pipe. A one-way valve 16 is fixedly installed at the output end of the pressure pump 15. A guide pipe 17 is fixedly installed between the output end of the one-way valve 16 and the right end of the bottom of the pressure seat 9. A water inlet valve 23 is fixedly installed at the upper end of the guide pipe 17. A PLC controller 2 is fixedly installed on the right end of the front surface of the testing platform 1.

[0025] In this technical solution, the setting of the fixed plate 5, the bidirectional screw 4, the movable plate 3, and the arc-shaped limiting frame 7 facilitates the sealing and fixing of the test mold 10 and the pressure seat 9. The setting of the PLC controller 2, the pressure pump 15, the water tank 14, the one-way valve 16, the guide pipe 17, and the water inlet valve 23 enables the delivery and pressurization of water inside the pressure seat 9 during the testing operation. This allows personnel to judge the impermeability of the concrete material sample by observing whether there is water seepage at the top within a certain time. Thus, the purpose of testing the impermeability of concrete material is achieved through the overall coordination. Moreover, the fixing operation during the testing process is convenient and quick, effectively improving the efficiency of the impermeability testing operation and bringing great convenience to the personnel's testing work.

[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, a synchronous pulley 11 is fixedly installed on the back of the bidirectional screw 4, and a synchronous belt 12 is connected between the middle ends of the two synchronous pulleys 11. Guide slide rods 8 are slidably connected between the two ends of the two moving plates 3, and the bottom of the guide slide rods 8 is fixedly connected to the top of the outer surface of the detection table 1.

[0028] In this technical solution, by setting up the synchronous pulley 11 and the synchronous belt 12, while the operator is operating one set of bidirectional screws 4 to rotate, it can drive another set of bidirectional screws 4 to rotate, which brings certain convenience to the operator. By setting up the guide slide rod 8, the purpose of guiding the moving plate 3 is achieved, so as to prevent the moving plate 3 from tilting due to force during the movement.

[0029] It should be noted that during use, personnel can install protective covers around the synchronous pulley 11 and the synchronous belt 12 to protect the area around them. At the same time, personnel can regularly maintain and service the bidirectional screw 4 during daily use to ensure that the bidirectional screw 4 can operate normally during long-term use.

[0030] Example 3:

[0031] Based on Embodiment 1, this utility model is as follows: Figure 3 and Figure 4 As shown, a rubber sealing gasket 24 is placed around the top of the pressure seat 9, with the top of the rubber sealing gasket 24 contacting the bottom of the mold 10. A pressure sensor 21 is fixedly installed at the bottom of the inner cavity of the pressure seat 9. Positioning grooves 19 are provided at both ends of the bottom of the mold 10. Positioning blocks 20 are fixedly connected to both ends of the top of the pressure seat 9. The surface of the positioning blocks 20 is movably connected to the surface of the positioning grooves 19. A return pipe 18 is fixedly installed between the left end of the bottom of the pressure seat 9 and the left end of the top of the water tank 14. A drain valve 22 is fixedly installed at the upper end of the return pipe 18. An exhaust valve 13 is fixedly installed at the lower right end of the mold 10 through a pipe. A transparent observation tube 6 is fixedly installed between the top of the exhaust valve 13 and the upper right end of the outer surface of the mold 10 through a pipe. A filling pipe is fixedly connected to the right end of the top of the water tank 14. A discharge valve is fixedly installed at the lower right end of the water tank 14 through a pipe.

[0032] In this technical solution, the rubber sealing gasket 24 effectively improves the sealing performance between the test mold 10 and the pressure seat 9 during installation. The pressure sensor 21 monitors the water pressure inside the pressure seat 9 and uploads the data to the display screen of the PLC controller 2 for easy monitoring. The positioning groove 19 and positioning block 20 effectively position the test mold 10 and the pressure seat 9 during placement, preventing misalignment. The return pipe 18 and drain valve 22 facilitate the discharge of water from the pressure seat 9 into the water tank 14 for collection after testing. The exhaust valve 13 and transparent observation tube 6 allow for easy air venting from the pressure seat 9 during the initial pressurization process.

[0033] It should be noted that during the pressing process of the concrete material test block inside the mold 10, after the pressing is completed, the bottom of the concrete material test block should not completely block the connection between the exhaust valve 13 and the mold 10, so as to ensure that the air can be discharged normally during the subsequent testing process.

[0034] The working principle of this utility model is as follows: When it is necessary to test the impermeability of concrete materials, firstly, the mold 10 containing the concrete material test block is placed on top of the pressure seat 9. Then, by manipulating the bidirectional screw 4 to rotate, the moving plate 3 and the arc-shaped limiting frame 7 are moved. During the movement of the arc-shaped limiting frame 7, it can contact the lower end of the mold 10 and exert downward pressure on the mold 10 along the inclined surface of the lower end of the mold 10, thereby causing the mold 10 to be tightly attached to the top of the pressure seat 9, thus completing the sealing and fixing between the mold 10 and the pressure seat 9. Subsequently, the pressure pump 15 is started by the PLC controller 2. The system can extract water from the water tank 14 and transport it to the pressure seat 9 through the check valve 16, the guide pipe 17, and the inlet valve 23. Under the continuous operation of the pressure pump 15, the water inside the pressure seat 9 can form a large pressure. Then, personnel can judge the impermeability of the concrete material sample by observing whether there is water seepage at the top within a certain time. This achieves the purpose of testing the impermeability of the concrete material. The fixed operation during the testing process is convenient and quick, which effectively improves the efficiency of the impermeability testing operation and brings great convenience to the personnel's testing work.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
