[0002] The concrete permeability testing apparatus mainly consists of a sealing sleeve and a permeability meter. The sealing sleeve is used to seal and fix the concrete specimen to ensure that no side leakage occurs during the experiment. The permeability meter can apply a stable water pressure to the specimen. By adjusting the water pressure and observing the water seepage of the specimen under different water pressures, the permeability performance of the concrete can be determined. It is usually also equipped with a pressure display device to accurately record and control the water pressure value in the experiment, thereby realizing a scientific evaluation of the concrete's permeability resistance.

[0003] A search revealed Chinese Patent Publication No. CN222419937U, which discloses a concrete permeability testing instrument, belonging to the field of concrete permeability testing equipment.

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.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a concrete impermeability testing device, comprising a workbench 1, a supporting square plate 10 fixedly connected to the top of the workbench 1, multiple mounting rings 8 equidistantly installed on the top of the supporting square plate 10, and a sealing sleeve 7 provided in the middle of each of the multiple mounting rings 8, allowing concrete to be placed inside for testing. A sealing base plate 24 is slidably connected to the bottom of each of the multiple sealing sleeves 7. A sliding block 21 is fixedly connected to the bottom of the inner side of the workbench 1. A second motor 18 is installed in the middle of the inner side of the workbench 1, providing power to subsequent processes. A gear 19 is fixedly connected to the output end of the second motor 18. A rack 22 is slidably connected inside the sliding block 21, with the front side of the rack 22 meshing with the rear side of the gear 19. A fixed rod 20 is rotatably connected to the left side of gear 19. A bearing plate 25 is fixedly connected to the top of the fixed rod 20. The outer side of the bearing plate 25 is slidably connected to the inner wall of the workbench 1. A support rod 23 is fixedly connected to the top of rack 22. The top of the support rod 23 is fixedly connected to multiple sealing base plates 24. A cleaning device 2 is installed on the top of the workbench 1. The cleaning device 2 is used to clean multiple sealing sleeves 7. An installation plate 11 is fixedly connected to the top of the front side of the workbench 1. Multiple buttons 12 are installed at equal intervals on the front side of the installation plate 11. The installation of multiple buttons 12 facilitates operation by the staff. An operating device 17 is installed on the right side of the front side of the workbench 1. Multiple screws 9 are threaded at equal intervals on the top of multiple mounting rings 8. The installation of multiple screws 9 makes the sealing sleeves 7 more securely installed. Specifically, after the experiment, the concrete is demolded. First, the second motor 18 is turned on, causing the starting gear 19 to rotate. The gear 19 meshes with the rack 22, and as the gear 19 rotates, the rack 22 moves downward along a predetermined trajectory, driving the support rod 23 and multiple sealing base plates 24 to move downward synchronously until they reach the top of the bearing plate 25. The installation of the sliding block 21 ensures that the rack 22 will not deviate during the movement. When the sealing base plate 24 moves downward again driven by the rack 22, it will drive the concrete block to move downward together, so that the concrete block can be separated from the sealing sleeve 7. Then, the rear side of the workbench 1 is opened, and the concrete block can be removed and cleaned. Through the above procedures, the concrete removal process is simplified and the work efficiency is improved.

[0027] Reference Figure 1 , Figure 3 and Figure 5The cleaning device 2 includes a support plate 204, which is fixedly connected to the top rear side of the workbench 1. A mixing box 201 is fixedly connected to the top of the support plate 204. A first motor 202 is installed on the right side of the mixing box 201, providing power to subsequent processes. A connecting rod 206 is fixedly connected to the output end of the first motor 202. Multiple rotating blades 207 are fixedly connected at equal intervals to the outer side of the connecting rod 206. The top left side of the mixing box 201 is connected to an inlet... Multiple nozzles 205 are equidistantly installed at the bottom of the feed pipe 203 and the mixing box 201. The installation of the nozzles 205 facilitates the cleaning of the sealing sleeve 7. A circular cover 3 is installed on the top of the feed pipe 203. A fixed short column 4 is fixedly connected to the top center of the circular cover 3. The installation of the circular cover 3 prevents dirt from entering through it. A slot plate 5 is fixedly connected to the front center of the mixing box 201. A notice plate 6 is set in the center of the slot plate 5. The installation of the slot plate 5 facilitates the replacement of the notice plate 6. Specifically, the cleaning fluid is injected into the mixing box 201 through the feed pipe 203. Then, the first motor 202 is turned on to drive the connecting rod 206 to start rotating. The outer edge of the connecting rod 206 is equipped with rotating blades 207, which rotate with the connecting rod 206 to stir the cleaning fluid and ensure that it is fully mixed. Subsequently, the cleaning fluid is sprayed out from multiple nozzles 205 at the bottom of the mixing box 201 and directly acts on multiple sealing sleeves 7 placed on the top of the workbench 1 for cleaning. Through the above process, it is ensured that the sealing sleeves 7 can be cleaned, thereby ensuring their sealing performance and reliability in subsequent use.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A cabinet door 13 is rotatably connected to the front left end of the workbench 1. A handle 14 is fixedly connected to the middle of the front right end of the cabinet door 13. A support base plate 15 is fixedly connected to the bottom of the workbench 1.

Specifically, the installation of handle 14 facilitates the opening of cabinet door 13, and the installation of casters 16 facilitates the movement of this device.

[0029] Working principle: When the concrete needs to be demolded after the experiment, the second motor 18 is turned on first, so that the gear 19 starts to rotate, which in turn meshes with the rack 22, causing the rack 22 to move downward. This, in turn, drives the support rod 23 and multiple sealing base plates 24 to move downward to the top of the bearing plate 25. The installation of the sliding block 21 prevents the rack 22 from shifting. When the sealing base plate 24 moves, the concrete moves downward. Then, the rear side of the workbench 1 is opened, which makes it easy to remove and clean the concrete. Through the above process, the removal of concrete is facilitated and the work efficiency is improved. The cleaning fluid flows into the mixing box 201 through the feed pipe 203. Then, the first motor 202 is turned on, causing the connecting rod 206 to start rotating. The outer side of the connecting rod 206 is equipped with rotating blades 207. Multiple rotating blades 207 rotate with the rotation of the connecting rod 206 to stir the cleaning fluid and ensure that the cleaning fluid is fully mixed. Then, the cleaning fluid is sprayed out from multiple nozzles 205 at the bottom of the mixing box 201. The sprayed cleaning fluid directly acts on multiple sealing sleeves 7 placed on the top of the workbench 1 to clean them. Through the above process, the sealing sleeves 7 are ensured to be cleaned efficiently and evenly, thereby ensuring their sealing performance and reliability in subsequent use.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
