Description

Technical Field

[0001] The invention relates to the technical field of concrete anti-seepage testing equipment, and in particular to concrete anti-seepage effect testing equipment for water conservancy project quality inspection. Background Art

[0002] The concrete impermeability test is a method for evaluating the impermeability of concrete materials. It tests the impermeability of concrete by simulating the penetration pressure conditions that concrete may encounter in actual use. This test is crucial for evaluating the durability and service life of concrete. In addition, studies have shown that the water seepage height of concrete is proportional to the square root of the product of the pressure head and the pressure time. This finding is of great significance for understanding the relationship between the impermeability of concrete and pressure and time. Through this test, we can understand the impermeability performance of concrete under different water pressure and time conditions, and provide a reference for actual engineering applications. The concrete impermeability test is an important test method that can not only evaluate the impermeability of concrete, but also provide a scientific basis for the durability and service life of concrete structures.

[0003] It should be noted that during the test, the specimen needs to be pressed into the test mold, and then multiple test molds are placed on the base of the tester in turn. Due to the large mass of the specimen, the placement of the test mold requires a lot of physical strength from the staff, and when the specimen is being tested, it is necessary to frequently check whether the specimen is leaking water, which further increases the workload of the staff. Moreover, when water seepage occurs, if the staff does not deal with it in the first time, water will continue to seep out, causing the entire tester to be soaked in water, which not only affects the test results, but may even cause secondary problems such as leakage in the tester.

[0027] In the present invention, by setting a synchronous lifting and locking mechanism, when installing the test mold, multiple test bodies are pushed into multiple embedding grooves respectively, and the driving screw is rotated to make the driving screw drive the lifting seat to move, and the lifting seat drives the integrated plate to move up through the rotating frame. After moving to the required position, the rotating frame is rotated so that the integrated plate corresponds to the positions of multiple placement bases.

[0028] Furthermore, in the present invention, through the setting of the automatic timing mechanism for water seepage, during the test, timing is performed through a stopwatch, and the start time is observed at the beginning, and then the stopwatch is started. If water seepage occurs in the specimen, the water is absorbed by multiple water absorption columns and absorbed by the supporting paper through the water absorption columns. The supporting paper becomes damp and softens and loses its supporting force. At this time, under the weight of the counterweight block, the counterweight block breaks through the supporting paper and moves downward, and drives the pull-down rod to drive the pull-down plate to move, and then the pull-down plate drives the trigger rod to trigger the stop button. At this time, the stopwatch stops timing, and when observing the experimental results, the staff only needs to simply calculate the start time and the time used by the stopwatch to accurately obtain the experimental results. There is no need to wait all the time, making the test operation simpler, more convenient and more accurate.

[0029] Furthermore, in the present invention, through the setting of the automatic water drain mechanism, after leakage occurs, the lower pull rod moves downward and drives the linkage rod to move, so that the linkage rod drives the connecting rod to move, and the movement of the connecting rod drives the water outlet sealing plate and the water inlet sealing plate to move synchronously, so that the water inlet sealing plate closes the water inlet pipe, avoiding continuous water inflow causing a large amount of water leakage, affecting the test problem. At the same time, the water outlet sealing plate moves to open the output pipe, and the output pipe recycles water, which can effectively avoid the problem of water leakage caused by the untimely closing of the valve, and further facilitates the operation of the test.

After moving to the desired position, the rotating frame 602 is rotated so that the integrated board 601 corresponds to the positions of the multiple placement bases 2. At this time, the driving screw 605 is rotated in the opposite direction, so that the lifting seat 604 moves down through the integrated board 601 of the rotating frame 602, and then the multiple test molds 3 are respectively placed on the multiple placement bases 2, so that the installation of the test molds 3 can be completed in a centralized manner, effectively reducing the burden on the staff.

[0051] It should be noted that in the embodiment of the present invention, during the test, timing is performed by the stopwatch 704. At the beginning, the start time is observed, and then the stopwatch 704 is started. If water seepage occurs in the specimen 4, the water is absorbed by the multiple water absorption columns 702 and absorbed by the supporting paper sheet 703 through the water absorption columns 702. The supporting paper sheet 703 becomes damp and softens and loses its supporting force. At this time, under the weight of the counterweight block 712, the counterweight block 712 breaks through the supporting paper sheet 703 and moves downward, and drives the lower pull rod 711 to move.

At the same time, the water outlet sealing plate 803 moves, so that the output pipe 802 is opened, and the output pipe 802 recycles water, which can effectively avoid the problem of water leakage caused by the untimely closing of the valve 10, and further facilitates the operation of the test.

A support spring 609 is installed on one side of the locking push-down rod 607, and the other end of the support spring 609 is installed on the inner wall of the retraction groove 606. It should be noted that, in the embodiment of the present invention, when installing the test mold 3, multiple test bodies 4 are pushed into multiple embedding grooves 613 respectively, so that the test bodies 4 squeeze the two locking push rods 607 to retract into the retraction groove 606, and drive the support spring 609 to be stressed until the position of the locking drive groove 608 corresponds to the locking push rod 607, that is, under the rebound force of the support spring 609, the locking push rod 607 is reset and stuck in the locking drive groove 608, and then the test mold 3 is stuck on the integrated board 601; it should be emphasized that the top side and the bottom side of the locking push rod 607 are plane settings, so when the integrated board 601 drives the test mold 3 to move through the locking push rod 607, the test mold 3 will not be separated from the integrated board 601, and the flat push test mold 3 can conveniently install the test mold 3 on the integrated board 601 or remove it from the integrated board 601.

It should be noted that in the embodiment of the present invention, when the test body 4 seeps water, the water is absorbed by the multiple water absorption columns 702 and the supporting paper sheet 703, so that the supporting paper sheet 703 becomes soft due to moisture.

[0060] More specifically, in the embodiment of the present invention, a counterweight block 712 is installed at the bottom end of the lower pull rod 711, and the counterweight block 712 contacts the top side of the supporting paper sheet 703. The supporting paper sheet 703 becomes soft due to moisture, causing the counterweight block 712 to lose support and drive the lower pull rod 711 to move downward.

[0061] In addition, a pull-down plate 713 is installed at the top of the pull-down rod 711, and a trigger rod 714 is installed at the bottom of the pull-down plate 713. The pull-down plate 713 moves downward, and the stop button 705 is pressed by the trigger rod 714 to stop the timing of the stopwatch 704. It should be noted that in the embodiment of the present invention, when water seepage occurs in the specimen 4, the water is absorbed by the multiple water absorption columns 702, and is absorbed by the supporting paper sheet 703 through the water absorption columns 702. The supporting paper sheet 703 becomes soft due to moisture and loses its supporting force. At this time, under the weight of the counterweight block 712, the counterweight block 712 breaks through the supporting paper sheet 703 and moves downward, and drives the pull-down rod 711 to move. The pull-down rod 711 drives the pull-down plate 713 to move, so that the pull-down plate 713 drives the trigger rod 714 to trigger the stop button 705. At this time, the stopwatch 704 stops timing. When observing the experimental results, the staff only needs to simply calculate the start time and the time used by the stopwatch to accurately obtain the experimental results, which effectively reduces the burden on the staff.

It should be noted that in the embodiment of the present invention, the lower pull rod 711 moves vertically in the blocking groove 709 through the blocking plate 710, so that the moving position of the lower pull rod 711 is limited.

[0063] Please refer to the instruction manual Figure 3 and Figure 10-11, more specifically, in the embodiment of the present invention, the automatic water discharge mechanism 8 also includes a water outlet sealing plate 803 and a water inlet sealing plate 804, both of which are located in the transfer switching box 801, and the water outlet sealing plate 803 and the water inlet sealing plate 804 are used to seal the output pipe 802 and the water inlet pipe 11 respectively. It should be noted that in the embodiment of the present invention, when the lower pull rod 711 moves downward, the water inlet sealing plate 804 seals the water inlet pipe 11, and the water outlet sealing plate 803 moves, and then the output pipe 802 is opened, so as to achieve the purpose of automatically switching water into the output pipe 802, avoid the leakage problem caused by continuous water supply, and ensure the test effect.

[0064] Please continue to refer to the instruction manual Figure 3 and Figure 10-11 , more specifically, in the embodiment of the present invention, a connecting rod 806 is connected between the water outlet sealing plate 803 and the water inlet sealing plate 804, a linkage rod 805 is movably installed on the top inner wall of the transfer switching box 801, and the top end of the linkage rod 805 is installed on the pull-down plate 713;

[0065] In addition, the connecting rod 806 is installed on the bottom end of the linkage rod 805, and the linkage rod 805 moves to drive the water outlet sealing plate 803 and the water inlet sealing plate 804 to move through the connecting rod 806. It should be noted that in the embodiment of the present invention, when the lower pull rod 711 moves downward, the linkage rod 805 is driven to move, so that the linkage rod 805 drives the connecting rod 806 to move, and the movement of the connecting rod 806 drives the water outlet sealing plate 803 and the water inlet sealing plate 804 to move synchronously, so that the water inlet sealing plate 804 closes the water inlet pipe 11 to avoid a large amount of water leakage caused by continuous water inflow, which affects the test problem, and at the same time, the water outlet sealing plate 803 moves to open the output pipe 802, and the output pipe 802 recycles water.

[0066] In summary, the working principle of the concrete anti-seepage effect test equipment for water conservancy project quality inspection provided by the embodiment of the present invention is:

[0067] When installing the test mold 3, multiple test pieces 4 are pushed into multiple embedding grooves 613 respectively, so that the test pieces 4 squeeze the two locking push rods 607 to retract into the retraction groove 606, and drive the support spring 609 to be stressed until the position of the locking driving groove 608 corresponds to the locking push rod 607, and the locking push rod 607 can be reset and stuck in the locking driving groove 608 under the rebound force of the support spring 609, and then the test mold 3 is stuck on the integrated board 601, and this operation is repeated so that multiple test molds 3 are stuck on the integrated board 601. At this time, the driving screw rod 605 is rotated so that the driving screw rod 605 drives the lifting seat 604 to move, and the lifting seat 604 drives the integrated board 601 to move up through the rotating frame 602. After moving to the required position , rotate the rotating frame 602 so that the integrated board 601 corresponds to the positions of the multiple placement bases 2, and at this time, the driving screw 605 is rotated in the opposite direction, so that the lifting seat 604 moves down through the integrated board 601 of the rotating frame 602, so that the multiple test molds 3 fall on the multiple placement bases 2 respectively, and the multiple plug-in seats 611 drive the multiple insertion rods 612 to be inserted into the multiple positioning seats 610, and then the test molds 3 correspond to the positions of the placement bases 2; in addition, with the continuous rotation of the driving screw 605, the integrated board 601 moves downward, and moves vertically in the lower pressure sleeve 615 through the lower pressure rod 614, so that the integrated board 601 drives the multiple test molds 3 to be in close contact with the multiple placement bases 2, so that the multiple test molds 3 can be installed synchronously and conveniently;

[0068] Furthermore, during the test, the stopwatch 704 is used for timing. At the beginning, the start time is observed, and then the stopwatch 704 is started. If water seepage occurs in the specimen 4, the water is absorbed by the multiple water absorption columns 702 and absorbed by the supporting paper sheet 703 through the water absorption columns 702. The supporting paper sheet 703 becomes damp and softens and loses its supporting force. At this time, under the weight of the counterweight block 712, the counterweight block 712 breaks through the supporting paper sheet 703 and moves downward, and drives the lower pull rod 711 to move. The lower pull rod 711 moves vertically in the blocking groove 709 through the blocking plate 710. At the same time, the lower pull rod 711 drives the lower pull plate 713 to move, so that the lower pull plate 713 drives the trigger rod 714 to trigger the stop button 705. At this time, the stopwatch 704 stops timing. When observing the experimental results, the staff only needs to simply calculate the start time and the time used by the stopwatch to accurately obtain the experimental results without having to wait all the time, making the operation of the test simpler, more convenient and more accurate.

[0069] Furthermore, after leakage occurs, the lower pull rod 711 moves downward and drives the linkage rod 805 to move, so that the linkage rod 805 drives the connecting rod 806 to move, and the movement of the connecting rod 806 drives the water outlet sealing plate 803 and the water inlet sealing plate 804 to move synchronously, so that the water inlet sealing plate 804 closes the water inlet pipe 11, so as to avoid a large amount of water leakage caused by continuous water inflow, which affects the test. At the same time, the water outlet sealing plate 803 moves, so that the output pipe 802 is opened, and the output pipe 802 recycles the water, which can effectively avoid the problem of water leakage caused by the failure to close the valve 10 in time, and further facilitates the operation of the test.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
