[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 9 As shown, a concrete test block impermeability tester includes a test box 5, a water storage tank 3 is provided inside the test box 5, a pressure supply pump 4 is provided at the front side of the water storage tank 3, and an adjustment mechanism 2 for providing different penetration pressures during testing is provided at the front side of the pressure supply pump 4, and also includes a detection mechanism 1;

[0029] In this embodiment: the detection mechanism 1 includes a plurality of mold bases 12, each mold base 12 is provided with a test mold 11 on the upper side, a lock hook ring 111 is fixed on the outer side of the test mold 11, a detection pull frame 13 is provided at the lower end of the mold base 12, and a detection hook 14 for buckling on the outer side of the lock hook ring 111 is provided at the upper end of the detection pull frame 13, a detection slide seat 15 extending into the mold base 12 is fixed at the center of the detection pull frame 13, and a reset spring 16 is sleeved on the outer side of the detection slide seat 15, and an observation hole 1 is opened at the top of the test mold 11 for observing the penetration of the test block 12, a water storage plate is provided on the upper side of the mold base 12, and a water outlet hole 122 is opened at the center of the water storage plate. A water inlet pipe 121 runs through the mold base 12, and the water outlet end of the water inlet pipe 121 is located between the water storage plate and the detection sliding seat 15. A notch is provided at the connection position between the detection pull frame 13 and the detection hook 14, and a horizontal axis running through the notch is provided at the lower end of the detection hook 14. A sealing ring 113 is provided at the bottom of the test mold 11 for preventing water from flowing out. Each test mold 11 equipped with a test block is buckled on the mold base 12, and then the detection hook 14 is turned over to make Its upper end is hooked on the top of the lock hook ring 111 of the test mold 11. At this time, a vertical detection hook 14 is hooked on the outside of each lock hook ring 111. Then, the water in the water storage tank 3 is sent into the mold base 12 through the adjustment mechanism 2 and the water inlet pipe 121 through the pressure supply pump 4. As the pressure inside the mold base 12 increases, the water will first enter the lower side of the test mold 11 through the water outlet 122. Since the test mold 11 is buckled on the water storage plate and the sealing ring 113 at the bottom of the test mold 11 will prevent the water from overflowing, as the water pressure increases, The water body will press the detection sliding seat 15 downward to make it move downward along the inside of the mold base 12. At this time, the reset spring 16 is compressed and pushes the detection pull frame 13 to move downward through the detection sliding seat 15. When the horizontal axis of the detection hook 14 is against the upper side of the notch of the detection pull frame 13, as the detection pull frame 13 continues to move downward, the three detection hooks 14 drive the test mold 11 to press it against the water storage plate of the mold base 12. The observation hole 112 on the top of the test mold 11 can be used to observe whether there is water seeping out from the top of the test block, and the time and pressure indications are recorded.

[0030] In this embodiment: the regulating mechanism 2 includes a high-pressure water tank 24, a sub-control assembly corresponding to the multiple mold bases 12 is provided on the top of the high-pressure water tank 24, and a pressure relief valve 25 is fixed on one side of the high-pressure water tank 24, and a pressure relief pipe 26 is provided on the end of the pressure relief valve 25 away from the high-pressure water tank 24. The water in the water storage tank 3 is sent to the high-pressure water tank 24 through the pressure supply pump 4, so as to provide the same pressure inside the multiple mold bases 12, and after the test is completed, the water in the high-pressure water tank 24 is sent out through the pressure relief pipe 26 by opening the pressure relief valve 25.

[0031] In this embodiment: the sub-control component includes a control valve 22, the upper end of the control valve 22 is provided with a water inlet conduit 21 for connecting to the water inlet pipe 121, and the lower end of the control valve 22 is provided with a water inlet branch pipe 23 for connecting to the high-pressure water tank 24. By opening or closing the control valve 22, the water in the high-pressure water tank 24 is sent into the corresponding mold base 12 through the water inlet branch pipe 23 and the water inlet conduit 21.

[0032] Working principle: During the test, firstly, three sets of sealing rubber rings are put on the outside of the test block, and then the test block is put into the test mold 11, and the test block is completely pressed into the test mold 11 by the extrusion equipment, and the end of the test mold 11 is flush with the end of the test block, and at the same time, the pressure pump 4 is started to send the water in the water storage tank 3 into the pressure pump 4, and then a plurality of control valves 22 are opened in sequence, so that the water in the high-pressure water tank 24 enters the mold base 12 through the water inlet branch pipe 23 and the water inlet conduit 21. At this time, the water in the mold base 12 will enter the upper position of the water storage plate from the water outlet hole 122. When the water on the water storage plate is at a certain height, the control valve 22 is closed. Since the bottom of the detection sliding seat 15 is supported by the reset spring 16, the detection sliding seat 15 will not move downward during this process;

[0033] Then, the test mold 11 with the test block installed is buckled into the corresponding mold base 12, and a sealed cavity is formed between the lower side of the test mold 11 and the water storage plate through the sealing ring 113 to prevent the water flowing out through the water outlet 122 from flowing out from the outer edge of the test mold 11 and the water storage plate. Then, the detection hook 14 on each detection pull frame 13 is turned over and buckled on the upper end of the corresponding lock hook ring 111, and then the control valve 22 is opened one by one and timing is started;

[0034] When the water on the lower side of the test mold 11 is filled, the water that continuously flows into the mold base 12 through the water inlet pipe 121 will push the detection sliding seat 15 to move downward. At this time, the reset spring 16 begins to compress, and the detection sliding seat 15 pushes the detection pull frame 13 to move downward. As the detection pull frame 13 moves downward, when the horizontal axis of the detection hook 14 contacts the upper side of the notch of the detection pull frame 13, the three detection hooks 14 will move downward with the detection pull frame 13 and pull the test mold 11 to be tightly buckled inside the mold base 12. Then, the observation hole 112 on the top of the test mold 11 can be observed multiple times to see whether there is water seeping out from the top of the test block. When water seeps out, the corresponding timing is stopped and the pressure is recorded.

[0035] Since the bottom of the test block inside the test mold 11 is attached to the top of the water storage plate of the mold base 12, when the test of a certain test block is completed, the corresponding control valve 22 is closed. At this time, as the water body continues to penetrate the test block, the pressure in the mold base 12 gradually decreases, and the corresponding reset spring 16 will push the detection sliding seat 15 to move upward. At the same time, the detection pull frame 13 on the lower side of the detection sliding seat 15 drives the detection hook 14 to move upward and break away from the corresponding test mold 11 to be buckled and locked, and then a certain test block can be taken out;

[0036] When the test is finished, the pressure relief valve 25 is opened to discharge the water in the high-pressure water tank 24 from the pressure relief pipe 26. At this time, there is no pressure inside the mold base 12. At this time, the reset spring 16 pushes the detection sliding seat 15 to move upward and reset. At this time, the detection pull frame 13 will also move upward with the detection sliding seat 15, and make the three detection hooks 14 disengage from the downward pull on the test mold 11. Then, the detection hooks 14 can be flipped over to disengage the test mold 11 from the lock, and then the test mold 11 can be flipped over to open.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
