Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to an anti-penetration concrete detector. Background Art

[0002] The focus on concrete's impermeability began with the construction of large-scale hydraulic engineering projects, primarily structures located below the waterline, such as concrete dams, canals, tunnels, and basements. Insufficient concrete impermeability can reduce the effectiveness of these structures and, in severe cases, cause accidents and economic losses. To ensure that concrete maintains good permeability throughout its service life, a concrete permeability test is required. The concrete permeability test is a test method used to evaluate concrete's permeability. Its purpose is to simulate the permeation effects to which concrete will be subjected during its service life, thereby testing the quality and performance of concrete and assessing the quality of the concrete material. Concrete permeability testing generally utilizes an anti-permeability concrete tester.

[0003] A search revealed a patent application with the publication number CN220323070U, which states that "by providing a humidity sensor and a pressure sensor, the numerical value generated by the concrete block during testing can be accurately reflected on the control terminal. At the same time, a pressure gauge provided on the pressurizer outside the test box can accurately control the pressure added to the box, thereby ensuring the accuracy of the test value and making the test results more accurate and reliable."

[0004] However, the above scheme still has certain deficiencies in actual use. Since the anti-penetration test requires multiple tests, and the scheme does not take other drying measures such as drying the concrete blocks, the interval time required for multiple tests of the concrete blocks is too long.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The present utility model discloses an anti-penetration concrete tester, comprising a test platform 1, the top of which is provided with a drying device 2 and a water storage tank 3, the water storage tank 3 being connected to the interior of the drying device 2 via an extraction pump; the test platform 1 comprises a test table 101, the top of which is fixedly mounted with a control panel 103 and a tool box 108, the bottom of which is fixedly mounted with a placement plate 102, the top of which is provided with an external power supply 104. A through-hole 105 is provided at the center of the test platform 101, the top of which is provided with a recovery tank 106, the top of which is fixedly mounted with a junction tube 107, the junction tube 107 being located below the through-hole 105.

[0022] The drying device 2 includes a placement frame 201 , an inner wall of the placement frame 201 is provided with a heating cavity 202 , and an inner wall of the heating cavity 202 is provided with an electric heating wire 203 and a heat conducting plate 204 .

[0023] A mounting frame 205 is fixedly mounted at the opening of the placement frame 201 , an electric push rod 206 is fixedly mounted on the top of the mounting frame 205 , an extrusion plate 207 is fixedly mounted on the movable end of the electric push rod 206 , and the extrusion plate 207 is located above the opening of the placement frame 201 .

[0024] By setting up the drying device 2, the continuous heating of the electric heating wire 203 inside the placement frame 201 can be used to transfer heat to the concrete block in the placement frame 201 through the heat conducting plate 204, so that the moisture in the concrete block is subjected to wrapped heating treatment. In combination with the electric push rod 206 at the top of the mounting frame 205, the concrete block in the placement frame 201 can be driven to be continuously squeezed, so that the moisture in the concrete block is squeezed outward, so that the concrete block is subjected to multi-stage drying treatment before the next anti-permeability test is carried out, thereby shortening the drying time of the concrete and improving the detection efficiency of the concrete.

[0025] Specifically, a guide fan 208 is fixedly installed inside the mounting frame 205, a skylight 209 is opened inside the extrusion plate 207, and the skylight 209 is located directly below the guide fan 208. A sliding cover 210 is slidably connected inside the skylight 209, and a handle is fixedly installed on the top of the sliding cover 210.

[0026] In this embodiment, the sliding cover 210 is pulled to expand the skylight 209, and then the guide fan 208 is started to form an air flow channel above the concrete block. The flowing air passes through the skylight 209 and contacts the concrete block, so that the concrete block is air-dried.

[0027] When in use, first place the concrete block in the placement frame 201, then start the extraction pump at the top of the water storage bucket 3, so that the extraction pump pumps the water in the water storage bucket 3 into the placement frame 201, and the water entering the placement frame 201 will automatically seep into the concrete block;

[0028] When the concrete block reaches the peak absorption saturation, the excess water no longer seeps into the concrete block but passes through the through-hole 105 and falls along the direction of the confluence tube 107 to the recovery barrel 106. The anti-permeability of the concrete block is finally calculated by collecting the amount of water in the recovery barrel 106.

[0029] When the concrete block needs to be dried, the electric heating wire 203 is activated, so that the electric heating wire 203 begins to be energized and generates heat, and then the heat is brought into contact with the concrete block along the heat conducting plate 204, so that the moisture in the concrete block is heated in an encapsulated manner;

[0030] Then, the electric push rod 206 is started again, and the electric push rod 206 can drive the squeezing plate 207 to continuously squeeze the concrete block in the frame 201, so that the moisture in the concrete block is squeezed outward, and the moisture in the concrete block is further discharged;

[0031] Then, the sliding cover 210 is pulled to unfold the skylight 209, and then the guide fan 208 is started to form an air flow channel above the concrete block. The flowing air passes through the skylight 209 and contacts the concrete block, so that the concrete block is air-dried.

[0032] In summary, the anti-penetration concrete tester, by setting up a drying device 2, utilizes the continuous heating of the electric heating wire 203 inside the placement frame 201 to transfer heat to the concrete block in the placement frame 201 through the heat conducting plate 204, so that the moisture in the concrete block is subjected to a wrapped heating treatment, and then cooperates with the electric push rod 206 at the top of the mounting frame 205 to drive the concrete block in the placement frame 201 to be continuously squeezed, so that the moisture in the concrete block is squeezed outward, so that the concrete block is subjected to multi-stage drying treatment before the next anti-penetration test is carried out, thereby shortening the drying time of the concrete and improving the detection efficiency of the concrete.
