Description
Technical Field
[0001] This utility model relates to the technical field of concrete testing, specifically to a permeability coefficient testing device for permeable concrete. Background Technology
[0002] Permeable concrete, also known as porous concrete, no-fines concrete, or permeable pavement, is a type of porous, lightweight concrete made from aggregates, cement, reinforcing agents, and water. It contains no fine aggregates; instead, coarse aggregates are coated with a thin layer of cement paste, creating a honeycomb structure with evenly distributed pores. Therefore, it is characterized by its breathability, water permeability, and light weight. The excellent air and water permeability of permeable concrete can effectively reduce the surface temperature of the road surface, mitigate the urban heat island effect, and effectively regulate the urban ecological balance. During use, the permeability coefficient of permeable concrete needs to be tested.
[0003] Existing permeability coefficient testing devices for permeable concrete typically involve directly adding the permeable concrete into the placement tank and then spraying it with water for testing. However, the wetting area of the permeable concrete is relatively fixed, making it impossible to evenly and fully wet the permeable concrete sample, thus affecting the experimental results. In addition, after the test, it is necessary to reach into the placement tank to retrieve the sample, but the internal operating space is relatively narrow, making it inconvenient to retrieve.
[0004] Therefore, we propose a permeability coefficient testing device for permeable concrete to address the problems mentioned above. Utility Model Content

The setting of the hose 9 facilitates the left and right movement of the spray pipe 10 and also enables the flow and transportation of clean water. This is a mature existing technology that can meet the needs of the device, so this application will not elaborate further.
[0021] The lifting component 5 is located in the middle of the rear side of the test platform 1. It can lift the permeable concrete sample after testing to the outside of the placement frame 4, which is convenient for the staff to quickly take it out.
[0022] The movable component 6 is located on the top of the test platform 1 near the rear side, which can drive the spray pipe 10 to move back and forth and spray, so as to achieve uniform spraying and wetting of the permeable concrete sample.
[0023] The movable component 6 includes two side plates 61 fixedly installed on the top of the test bench 1 near the rear side. The side plates 61 are arranged left and right. A threaded rod 62 is provided on the opposite side of the side plates 61 near the front side. The right end of the threaded rod 62 is movably installed on the right side plate 61, and the left end of the threaded rod 62 extends through to the outside of the left side plate 61. A servo motor B63 is provided on the left side of the left side plate 61. The output end of the servo motor B63 is fixedly connected to the left end of the threaded rod 62. A threaded sleeve 64 is threadedly installed on the outside of the threaded rod 62 near the right end.
[0024] Under specific conditions, the operation of the servo motor B63 will drive the threaded rod 62 to run.

Once placed, the suction pump 8 will start, drawing clean water from the water tank 7. This water will then be transported to the spray pipe 10 via the connecting pipe, hose 9, and connecting tube. The sample can then be sprayed onto the sample for testing. Next, the servo motor B63 will start, causing the threaded rod 62 to rotate. The rotation of the threaded rod 62 will cause the threaded sleeve 64 to move back and forth, and this movement, via the L-shaped fixing rod 101, will cause the spray pipe 10 to move back and forth, facilitating uniform spraying of the sample and improving the accuracy of the test data.
[0031] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1-8 The lifting assembly 5 includes a support plate 51 fixedly installed at the middle of the rear side of the test bench 1 and a servo motor A52 set at the top of the support plate 51 near the rear upper part. A turntable 53 is fixedly installed at the output end of the servo motor A52, and a fixed shaft 54 is fixedly installed at the front side of the turntable 53 near the edge. A sliding frame 55 is slidably sleeved on the outer side of the fixed shaft 54. A connecting rod 56 is fixedly installed at the top of the sliding frame 55 near the left and right sides. A lifting plate 57 is fixedly installed at the upper end of the connecting rod 56. A U-shaped rod 58 is fixedly installed at the bottom of the lifting plate 57 near the left and right sides. The end of the U-shaped rod 58 away from the lifting plate 57 extends into the inner cavity of the rectangular opening and is fixedly installed with a top plate 59. A drain port is opened at the upper middle part of the top plate 59, and the outer side of the top plate 59 is fitted with the inner wall of the inner cavity of the rectangular opening. The top plate 59 can be driven to move upward, so that the sample can be pushed out to the outside of the placement frame 4, which is convenient for the staff to pick up and take out.
[0032] A mounting bracket 521 is fixedly installed at the middle of the top of the servo motor A52, and the lower end of the mounting bracket 521 is fixedly installed on the support plate 51, which serves to support and fix the servo motor A52.
[0033] Guide plates 551 are fixedly installed at the middle of both sides of the sliding frame 55, and guide rods 552 are slidably installed through the guide plates 551. The lower ends of the guide rods 552 are fixedly installed on the test platform 1, which serves to guide and limit the sliding frame 55 when it moves up and down, so that it moves up and down stably.
[0034] In this embodiment: when the sample is sprayed, the sprayed water will fall into the water collection tank 3 through the drain port. After the test is completed, the servo motor A52 can be driven to run. When the servo motor A52 runs, it will drive the turntable 53 to rotate. When the turntable 53 rotates, it will drive the sliding frame 55 to move upward through the fixed shaft 54. When the sliding frame 55 moves upward, it will drive the lifting plate 57 to move upward through the connecting rod 56. When the lifting plate 57 moves upward, it will drive the top plate 59 to move upward through the U-shaped rod 58, so that the sample can be ejected for easy handling by the staff. After removal, the top plate 59 can be restored to its original position by reversing the operation.
[0035] Working Principle: During use, the operator places the permeable concrete sample on the test platform 1, ensuring it is within the inner cavity of the placement frame 4. Once placed, the suction pump 8 operates, drawing water from the water tank 7. This water is then transported through the connecting pipe, hose 9, and connecting tube to the spray pipe 10, allowing for spraying the sample for testing. Simultaneously, the servo motor B63 operates, driving the threaded rod 62 to rotate. This rotation of the threaded rod 62 causes the threaded sleeve 64 to move back and forth, which in turn moves the spray pipe 10 back and forth via the L-shaped fixing rod 101, facilitating the testing of the sample. Evenly spraying the sample helps improve the accuracy of the test data. In addition, when the sample is sprayed, the sprayed water will fall into the water collection tank 3 through the drain port. After the test is completed, the servo motor A52 can be driven to run. When the servo motor A52 runs, it will drive the turntable 53 to rotate. When the turntable 53 rotates, it will drive the sliding frame 55 to move upward through the fixed shaft 54. When the sliding frame 55 moves upward, it will drive the lifting plate 57 to move upward through the connecting rod 56. When the lifting plate 57 moves upward, it will drive the top plate 59 to move upward through the U-shaped rod 58, which can push the sample out for easy handling by the staff. After removal, the top plate 59 can be returned to its original position by reversing the operation.
