Description

Technical Field

[0001] This utility model relates to a testing device, specifically a testing device for the impermeability of concrete. Background Technology

[0002] The impermeability of concrete refers to its ability to resist the penetration of pressurized water. Generally, when the design requires impermeability of the concrete or when the pouring location requires impermeability, concrete samples should be taken and impermeability tests should be conducted. Currently, concrete impermeability is generally tested using a concrete permeability meter. However, the concrete permeability meters currently in use still require manual sealing of the concrete permeability test blocks, which not only increases the workload of technicians but also introduces human error into the test, affecting the test data. Utility Model Content

[0003] The purpose of this invention is to provide a concrete impermeability testing device that solves the problems of time-consuming and labor-intensive automatic sealing of concrete impermeability test blocks, which affects the test results.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A concrete permeability testing device includes a protective box with multiple fixed positions for placing concrete permeability test blocks. The protective box is equipped with an automatic sealing component, which is connected to a sealing mold adapted to the concrete permeability test blocks. The protective box has a cavity, and a water pressure control component is disposed inside the cavity. The water pressure control component is connected to the fixed positions. The concrete permeability test blocks are equipped with sealing rings.

[0006] Furthermore, the automatic sealing assembly includes a telescopic cylinder, a guide post, and a fixing plate. The telescopic cylinder and the guide post are evenly distributed on the protective box, and there are two telescopic cylinders and two guide posts, which are spaced apart. The fixing plate is provided with connecting holes, and the fixing plate is connected to the telescopic cylinder and the guide post through the connecting holes.

[0007] Furthermore, the water pressure control assembly includes a water tank, a water pump, an expansion tank, and a circulation pipe assembly. The water tank is connected to the water pump via a first connecting pipe, the water pump is connected to the circulation pipe assembly via a second connecting pipe, and the expansion tank is connected to the second connecting pipe via a third connecting pipe.

[0008] Furthermore, the water tank is equipped with a water filter, a level controller, and a thermometer. The water filter can filter impurities in the water tank, the level controller is used to control the liquid level in the water tank, and the thermometer is used to control the temperature of the water in the water tank.

[0009] Furthermore, the second connecting pipe is equipped with a check valve and a shut-off valve. The check valve is located near the water pump side, and the shut-off valve is located near the circulation pipe group side. The check valve is used to prevent liquid backflow, and the shut-off valve is used to control the opening and closing of the pipe.

[0010] Furthermore, the water tank is connected to a third connecting pipe via a hose, and the hose and the third connecting pipe are connected via a safety valve, which is used to control the water tank pressure.

[0011] Furthermore, the two ends of the circulation pipe assembly are respectively connected to the water tank and the second connecting pipe; the circulation pipe assembly includes a first main pipe and a second main pipe, the first main pipe is connected to the water tank, and the second main pipe is connected to the second connecting pipe.

[0012] Furthermore, the first main pipe is connected to a first branch pipe, a second branch pipe, and a third branch pipe, and the second main pipe is connected to a fourth branch pipe, a fifth branch pipe, and a sixth branch pipe; the first and fourth branch pipes, the second and fifth branch pipes, and the third and sixth branch pipes are respectively connected to the fixed position through a liquid guide pipe.

[0013] Furthermore, the expansion tank is fixed inside the protective box by a fixing bracket.

[0014] Furthermore, the protective box includes support legs and a door, with the door located on one side of the protective box and the support legs located at the bottom of the protective box.

[0015] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0016] This invention adds an automatic sealing component to the protective box. When sealing the concrete impermeability test block is required, the telescopic cylinder retracts, causing the fixed plate to lower the sealing mold until it fits onto the concrete impermeability test block. The concrete impermeability test block is equipped with a sealing ring to increase the sealing performance. The telescopic cylinder and guide columns are spaced apart, making the descent of the fixed plate more stable, reducing the impact of sealing on the experimental results, and improving the accuracy of the results. This invention not only reduces the workload of technicians but also improves the accuracy and reliability of experimental results. Attached Figure Description

[0022] like Figures 1 to 5 As shown, a concrete permeability testing device includes a protective box 1 with multiple fixed positions 2 for placing concrete permeability test blocks 3. The protective box 1 is equipped with an automatic sealing assembly, which is connected to a sealing mold 4 adapted to the concrete permeability test blocks 3. The protective box 1 has a cavity containing a water pressure control assembly, which is connected to the fixed positions 2. The concrete permeability test blocks 3 are equipped with sealing rings. When the concrete permeability test blocks 3 are placed on the fixed positions 2, the automatic sealing assembly drives the sealing mold 4 to fit onto the concrete permeability test blocks 3, sealing the gap between the concrete permeability test blocks 3 and the sealing mold 4 through the sealing rings to prevent inaccurate test results. Subsequently, the water pressure control assembly drives water to apply a fixed water pressure to the concrete permeability test blocks 3 to test the concrete's permeability resistance. The automatic sealing assembly driving the sealing mold 4 to fit onto the concrete permeability test blocks 3 reduces the workload of technicians, eliminating the need for technicians to seal each concrete permeability test block 3, which is time-consuming and labor-intensive.

[0023] The automatic sealing assembly includes a telescopic cylinder 11, guide posts 12, and a fixing plate 13. The telescopic cylinders 11 and guide posts 12 are evenly distributed on the protective box 1, with two of each type, spaced apart. The fixing plate 13 has connecting holes, through which it connects to the telescopic cylinders 11 and guide posts 12. When the telescopic cylinders 11 retract, they drive the fixing plate 13 to descend. The telescopic cylinders 11 located diagonally opposite each other on the fixing plate 13 increase the stability of the fixing plate 13 during descent, reducing the impact of the sealing process on the experimental results.

[0024] The water pressure control assembly includes a water tank 21, a water pump 22, an expansion tank 23, and a circulation pipe assembly 24. The water tank 21 is connected to the water pump 22 via a first connecting pipe 25, and the water pump 22 is connected to the circulation pipe assembly 24 via a second connecting pipe 26. The expansion tank 23 is connected to the second connecting pipe 26 via a third connecting pipe 27. The expansion tank 23 can stabilize the water pressure, ensuring that the water pressure in each fixed position 2 is the same. The second connecting pipe 26 is equipped with a check valve 28 and a shut-off valve 29. The check valve 28 is located near the water pump 22, and the shut-off valve 29 is located near the circulation pipe assembly 24. The check valve 28 is used to prevent liquid backflow, and the shut-off valve 29 is used to control the opening and closing of the pipes. The water tank 21 is connected to the third connecting pipe 27 via a hose 31, and the hose 31 and the third connecting pipe 27 are connected via a safety valve 32. The safety valve 32 is used to control the pressure of the water tank 21. The circulation pipe assembly 24 is connected at both ends to the water tank 21 and the second connecting pipe 26, respectively. The circulation pipe assembly 24 includes a first main pipe 33 and a second main pipe 34. The first main pipe 33 is connected to the water tank 21, and the second main pipe 34 is connected to the second connecting pipe 26. A first branch pipe 35, a second branch pipe 36, and a third branch pipe 37 are connected to the first main pipe 33, and a fourth branch pipe 38, a fifth branch pipe 39, and a sixth branch pipe 41 are connected to the second main pipe 34. The first branch pipe 35 and the fourth branch pipe 38, the second branch pipe 36 and the fifth branch pipe 39, the third branch pipe 37, and the sixth branch pipe 41 are respectively connected to the fixed position 2 through the liquid guide pipe 42. The water tank 21 is equipped with a main switch and a pressure control valve. After the main switch is turned on, the water pump 22 starts to work. Water pump 22 pumps liquid from water tank 21 into first connecting pipe 25, and then into second main pipe 34 via second connecting pipe 26. First main pipe 33 ultimately delivers water to first branch pipe 35, fourth branch pipe 38, second branch pipe 36, fifth branch pipe 39, third branch pipe 37, and sixth branch pipe 41, respectively. Subsequently, it is delivered to fixed position 2 via liquid guide pipe 42 to continuously pressurize concrete impermeable test block 3 in fixed position 2, testing the impermeability performance of concrete impermeable test block 3. Water enters second main pipe 34 from second connecting pipe 26, and then enters fixed position 2 via liquid guide pipe 42. First main pipe 34 is equipped with a shut-off valve; during pressurization, the shut-off valve closes first main pipe 34. After pressurization, the pressure inside water tank 21 is lower than the external pressure, and the water in liquid guide pipe 42 returns to water tank 21 through first main pipe 34.

[0025] The water tank 21 is equipped with a water filter 45, a level controller 46, and a thermometer 47. The water filter 45 filters impurities from the water tank 21, the level controller 46 controls the liquid level in the water tank 21, and the thermometer 47 controls the temperature of the water in the water tank 21. The water filter 45 pre-treats the water in the water tank 21 to prevent it from affecting the accuracy of the experiment. The thermometer 47 controls the temperature of the water in the water tank 21, keeping the water temperature at a level suitable for the experiment.

[0026] The expansion tank 23 is fixed inside the protective box 1 by a fixing bracket 48. The protective box 1 includes a support leg 49 and a door 50. The door 50 is located on one side of the protective box 1, and the support leg 49 is located at the bottom of the protective box 1. The door 50 facilitates the maintenance of the water pressure control components inside the protective box 1, and the support leg 49 facilitates the support of the protective box 1.
