[0002] Concrete is a building material used in engineering construction. To ensure the application effect, it is very important to detect various properties of concrete materials. Concrete water permeability detection is mainly used to ensure the water permeability of concrete and evaluate the actual application effect of concrete during water permeability to ensure the quality of concrete.

[0003] The patent with the patent authorization announcement number CN211553700U discloses a concrete water permeability detection device. By using a spiral water outlet pipe as a water supply mechanism, this patent can evenly sprinkle water on the concrete specimen, solving the problem of uneven manual pouring. The liquid level sensor set in the spiral water outlet pipe can send liquid level information to the controller in real time, and then the infrared receiving tube and infrared transmitting tube set in the water collection cavity are used to collect the liquid level information in the water collection cavity to replace manual calculation of the concrete water permeability. However, there are still some deficiencies in the actual use of this patent.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] Please refer to Figures 1-4, a concrete water permeability detection device, including a support base 1, a support frame 2 is fixedly connected to the support base 1, a protection frame 3 is fixedly connected inside the support frame 2 by welding, a positioning frame 301 is fixedly connected inside the protection frame 3, a concrete test block 4 is placed inside the positioning frame 301, a liquid outlet plate 5 is fixedly connected to the support frame 2 and located below the protection frame 3, four guide rods 8 are fixedly connected to the support base 1 and are symmetrically distributed in pairs left and right, a placement table 7 is slidably arranged on the four guide rods 8, a first elastic member 9 for resetting the placement table 7 is sleeved on the guide rods 8, two ends of the first elastic member 9 are respectively connected to the placement table 7 and the support base 1, a liquid storage frame 6 is arranged on the placement table 7, the liquid storage frame 6 is located below the liquid outlet plate 5, the liquid storage frame 6 is used for collecting the water permeating through the concrete test block 4, a baffle 29 is arranged on the placement table 7, the baffle 29 is used for restricting the position of the liquid storage frame 6 to prevent the liquid storage frame 6 from moving, a pressing block 10 is arranged at the bottom of the placement table 7, a trigger plate 11 is arranged on one side of the support base 1 close to the pressing block 10, a warning device 12 is arranged on the support base 1, the pressing block 10 is in contact with the trigger plate 11 to trigger the warning device 12 for prompting, and a sealing device for sealing the gap between the positioning frame 301 and the concrete test block 4 is arranged on the support frame 2.

[0024] Please refer to Figure 4 , the sealing device includes a support seat 13, the support seat 13 is fixedly connected to the rear side of the support frame 2, an extrusion frame 14 is slidably arranged on the support seat 13, a clamping block 15 is arranged on the extrusion frame 14, the clamping block 15 is used for fixing the extrusion frame 14 on the support seat 13, the clamping blocks 15 are commonly connected with a connecting plate 30, and the two clamping blocks 15 are conveniently moved simultaneously by using the connecting plate 30. A second elastic member 16 is sleeved on the extrusion frame 14, two ends of the second elastic member 16 are respectively connected to the extrusion frame 14 and the support seat 13. Initially, the extrusion frame 14 is pulled downward, and the second elastic member 16 is in a stretched state. An air inflation bag 17 is arranged between the support seat 13 and the extrusion frame 14. One end of a guide air pipe 18 is connected and communicated with the air inflation bag 17. An annular air bag 19 is embedded in the positioning frame 301. The other end of the guide air pipe 18 passes through the support frame 2 and is connected and communicated with the annular air bag 19. By inflating the annular air bag 19 through the air inflation bag 17, the annular air bag 19 can be inflated to fill the gap between the concrete test block 4 and the positioning frame 301, playing a sealing role and preventing water leakage during detection.

[0025] During use, first place the concrete test block 4 into the positioning frame 301. Then remove the clamping block 15. Under the restoring elastic force of the second elastic member 16, the extrusion frame 14 moves upward to compress the air-filled bag 17, and the internal gas is input into the annular air bag 19. The annular air bag 19 expands to fill the gap between the concrete test block 4 and the positioning frame 301, preventing water from flowing out through the gap between the concrete test block 4 and the positioning frame 301 during detection and affecting the detection, thereby improving the accuracy of the detection. Then, manually sprinkle water on the surface of the concrete test block 4 for testing. The water permeating from the concrete test block 4 flows downward into the liquid storage frame 6. When the water inside the liquid storage frame 6 reaches a certain weight, the placement table 7 drives the liquid storage frame 6 to move downward, causing the pressing block 10 to contact the trigger plate 11 to trigger the alarm 12. The alarm 12 gives an alarm for prompt, indicating that the water permeability of the tested concrete test block 4 is relatively poor, achieving rapid detection and thus improving the detection efficiency.
