[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] The concrete impermeable instrument 1 is an instrument that utilizes the principle that the pressure is equal everywhere in a sealed container (ignoring the water level difference), uses a water pump to supply pressure to the entire system, and realizes the upward penetration of pressure water by the test piece in the test mold 3 through the pressure of the electric contact pressure gauge or pressure controller, thereby measuring the impermeability of the test piece and calculating the impermeability index. The pressure value is displayed on the pressure display instrument through the sensor, and the automatic pressure increase and automatic test can be realized according to the set program, thereby reducing the burden of the staff.

[0020] Based on the time-consuming and labor-intensive technical defects of the prior art, please refer to Figs. 1-2This utility model provides an automatic concrete permeability testing instrument 1. By adding a camera 6 and an LED tri-color alarm light 5, it enables unmanned real-time monitoring of the test, avoiding wasted manpower and saving costs. The instrument includes a concrete permeability testing instrument 1, on which a test mold 3 is detachably installed. A control valve 2 is set on the front of the concrete permeability testing instrument 1. A bracket 4 is also installed on the concrete permeability testing instrument 1. The camera 6 and the LED tri-color alarm light 5 are installed on the top of the bracket 4. In use, six test specimens are installed and fixed on the test mold 3. The camera 6 and the LED tri-color alarm light 5 are connected to the network and powered on. The concrete permeability testing instrument 1 is adjusted to the pressure value set for the specified permeability grade. The test begins. The camera 6 can monitor the water seepage of the test blocks in real time, thus enabling unmanned real-time monitoring of the test and avoiding wasted manpower, thereby saving costs. Different colored lights can be lit by the monitoring equipment to remind the test personnel to complete the subsequent test and issue the original test record and report.

[0021] In practical applications, testing a single specimen often yields unrepresentative results. Therefore, multiple specimens are required for testing. To achieve this, six sets of test molds 3, control valves 2, and LED tri-color alarm lights 5 are used. This allows for simultaneous testing of six specimens, increasing data diversity and making the test results more accurate.

[0022] When camera 6 detects water seepage on specimen mold 3, it needs to alert the staff. Therefore, camera 6 is electrically connected to LED tri-color alarm light 5. Each group of specimens corresponds to one LED tri-color alarm light 5. If water seeps from the periphery of the specimen during the test, the corresponding LED tri-color alarm light 5 will illuminate yellow, reminding the test personnel to reseal according to Clause 6.1.3 of standard GB / T 50082-2009 "Standard for Long-Term Performance and Durability Test Methods of Ordinary Concrete". If camera 6 detects water seepage in any of the six groups of specimens during the test, the corresponding LED tri-color alarm light 5 will illuminate red. When the specified water pressure is reached, if four or more of the six specimens in each group do not seep water, the corresponding LED tri-color alarm light 5 will illuminate green, indicating the concrete permeability test is complete. This reminds the test personnel to complete subsequent test procedures and issue original test records and reports.

[0023] During the monitoring process of camera 6, the monitoring data needs to be remotely sent to the test personnel. For this purpose, camera 6 has a built-in wireless module and connects to the remote terminal signal through the wireless module. Camera 6 can not only observe the water seepage of concrete and transmit it to the LED three-color alarm light 5, but also connect to the test personnel's mobile phone or computer through the wireless signal, and send alarm information to the test personnel's mobile phone or computer, so that the test personnel can understand the progress of the concrete seepage resistance test in real time.

[0024] In actual use, the test mold 3 may be damaged, which will affect the test results. In order to replace the test mold 3, a base 7 is fixed on the concrete permeability tester 1 at the position below the test mold 3. The base 7 is fixed with a number of studs 8 arranged in a ring. The test mold 3 is sleeved on the studs 8, and the top of the studs 8 is threaded with a nut 9. The use of the studs 8 and the nut 9 makes it easy to disassemble and assemble the test mold 3 for replacement.

[0025] During the test, pressurized water is permeated upwards into the specimen in the mold 3. If there is a gap between the mold 3 and the base 7, water leakage will occur. To avoid this problem, an annular groove 71 is provided on the base 7, and a sealing ring 10 is placed in the annular groove 71. Under the action of the sealing ring 10, water leakage at the bottom can be avoided during the test, thus improving the accuracy of the test results.

[0026] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
