Description

Technical Field

[0001] This utility model relates to the field of mortar impermeability testing technology, specifically a test mechanism for the impermeability of basalt chip waterproof mortar. Background Technology

[0002] Basalt stone chips can enhance the overall performance of waterproof mortar when applied. Basalt possesses properties such as compressive strength, corrosion resistance, and abrasion resistance. As aggregate, its chips can improve mortar gradation and increase density, thereby enhancing waterproofing and impermeability. Simultaneously, basalt stone chips have good compatibility with cementitious matrices, reducing porosity, lowering the risk of cracking, and extending the service life of the waterproof layer, making them highly valuable in construction and road engineering. To further investigate the impact of the amount of stone chips added on the performance of waterproof mortar, multiple impermeability tests are typically required to determine the optimal addition amount.

[0003] The utility model patent with announcement number CN221174321U discloses a waterproof mortar anti-permeability testing device, which includes a workbench and a base box. The bottom end of the workbench is fixedly connected to the top end of the base box. It also includes a sealing mechanism, a clamping mechanism, a ejection mechanism, and a pressurizing mechanism. During testing, the clamping mechanism clamps and fixes the test block, and the pressurizing mechanism pressurizes water and inputs it under the test block to observe whether water seepage occurs above the test block. After the test is completed, the ejection mechanism can eject the test block from the clamping mechanism, making it easy to remove the mortar test block and improving the convenience of testing.

[0004] While the aforementioned device can detect the impermeability of mortar, the method for determining whether the impermeability limit of the test block has been reached is visual observation, i.e., judging whether the impermeability limit has been reached by observing whether water seeps from the top of the test block. This method has a large margin of error in practice and is largely affected by the subjectivity of the testing personnel. Moreover, the testing personnel need to constantly observe whether water seeps through the observation port throughout the entire testing process, which consumes a lot of their attention. When conducting continuous testing for a long time, it will place a significant physical burden on the testing personnel. Therefore, in order to address the above problems, a test mechanism for the impermeability of basalt chip waterproof mortar is proposed. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide a testing mechanism for the impermeability of basalt chip waterproof mortar. This mechanism includes a permeability monitoring device to monitor whether the test sample has reached the required standard. The device comprises two conductive contacts that contact the upper surface of the test sample. When the test sample reaches its impermeability limit, a water film will seep out from its upper surface. At this point, the two conductive contacts can achieve electrical connection through the aqueous solution, activating the power supply circuit of a buzzer. The buzzer then alerts the testing personnel that the test sample has reached its impermeability limit. This technical solution quantifies the criteria for judging the impermeability limit, is not affected by the subjective judgment of the testing personnel, and significantly reduces the error in the test results. Simultaneously, the testing personnel can focus on water pressure control during the test, without expending significant effort observing for seepage. This solves the problem in comparative techniques where judging whether the impermeability limit has been reached by observing seepage on the top of the test sample is prone to significant errors in practice, easily influenced by the subjectivity of the testing personnel, and consumes a large amount of their attention.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0007] A test mechanism for the impermeability of basalt chip waterproof mortar includes a test platform with a hydraulic mechanism and an internal water supply mechanism; a placement boss on which a test sample is placed; a sealing cover installed at the bottom of the hydraulic mechanism and directly above the placement boss, which completely covers the test sample when lowered; and a permeability monitoring mechanism housed within the sealing cover. The permeability monitoring mechanism includes a buffer frame fixedly connected to the sealing cover, with a bottom cylinder at its base and two symmetrically arranged conductive contacts mounted on the bottom cylinder. Furthermore, the sealing cover... A buzzer is installed on the cover, and two conductive contacts form a switch connected in series in the power supply circuit of the buzzer. When the test sample shows signs of seepage, the conductive contacts are connected through the seepage solution, which in turn activates the power supply circuit of the buzzer. The buzzer then alerts the test personnel that the test sample has reached its seepage resistance limit. The above technical solution can quantify the judgment criteria of the seepage resistance limit, is not affected by the subjective judgment of the test personnel, and can significantly reduce the error of the test results. At the same time, the test personnel can focus on water pressure control during the test without spending a lot of energy observing whether seepage occurs.

[0008] In one possible implementation, a water-absorbing conductive ring is detachably installed on the lower end face of the bottom cylinder. The ring is made of porous absorbent paper and filled with water-soluble electrolyte filler. The water-absorbing conductive ring can further improve the conductivity of the water film that seeps out of the test sample. When a water film appears on the surface of the test sample, it will be absorbed by the water-absorbing conductive ring, which will then dissolve the electrolyte material to form a salt solution, significantly improving the conductivity of the water film. This avoids the situation where the conductive contacts cannot be connected in time due to the poor conductivity of the water film, thus failing to detect the problem in time.

[0009] In one possible implementation, a plurality of locking shafts arranged in a circumferential array are fixedly provided on the lower end face of the bottom cylinder. The water-absorbing conductive ring is provided with locking holes corresponding to the locking shafts, and the water-absorbing conductive ring is provided with contact through holes corresponding to the conductive contacts. The water-absorbing conductive ring can be quickly installed and removed through the locking between the locking shafts and the locking holes, so that it can be quickly replaced after one test.

[0010] In one possible implementation, a power supply battery is installed inside the buffer frame. Its positive terminal is electrically connected to the positive terminal of the buzzer via a wire, and its negative terminal is electrically connected to one of the conductive contacts via a wire. The other conductive contact is electrically connected to the negative terminal of the buzzer via a wire. When the two conductive contacts are connected via a water film, the power supply battery can supply power to the buzzer to make it work and issue an alarm.

[0011] In one possible implementation, the buffer frame includes several guide rods arranged in a circumferential array, with anti-detachment plates fixedly connected to their bottom ends, and a movable plate slidably disposed on them. In addition, a buffer spring is sleeved on the guide rod. When the bottom cylinder moves to fit against the upper surface of the test sample, as the sealing cover continues to press down, the movable plate will overcome the thrust of the buffer spring and move upward, avoiding damage to the bottom cylinder due to the continuous downward movement of the sealing cover. At the same time, the buffer spring can continuously apply thrust, so that the bottom cylinder fits tightly against the upper surface of the test sample.

[0012] In one possible implementation, a support ring is fixedly provided at the top of the placement boss, and a sealing gasket is fitted on it. In addition, a water inlet component with a sealed connection is provided inside the placement boss. The above structure can achieve a sealed connection between the support ring and the test sample block through the sealing gasket, preventing water from seeping out through the gap.

[0013] In one possible implementation, the water supply mechanism includes an integrated pump and tank mechanism, which consists of a water tank and an internally installed pump body. The pump body's output end is hermetically connected to a water supply pipe that communicates with the water inlet. A return pipe leading to the water tank is hermetically connected to the water supply pipe. Both the water supply pipe and the return pipe are equipped with check valves. When supplying water, the check valve on the water supply pipe is open, and the check valve on the return pipe is closed. The pump body pumps water through the water supply pipe to the water inlet for seepage detection. After the detection is completed, the check valves reverse their opening and closing states, allowing water to flow into the water tank through the return pipe.

[0014] In one possible implementation, the enclosure includes a shell with a force transmission frame fixedly mounted on its top and connected to a hydraulic mechanism, and an inner sealing rubber cylinder fixedly mounted on the inner wall of the shell. The above structure can achieve a tight connection between the shell and the test sample through the inner sealing rubber cylinder, preventing water from seeping out through gaps.

[0015] In summary, this utility model has the following beneficial technical effects:

[0016] The mortar impermeability testing mechanism is equipped with a permeability monitoring device to monitor whether the judgment standard has been met. It includes two conductive contacts that are in contact with the upper surface of the test sample. When the test sample reaches the impermeability limit, a layer of water film will seep out from its upper surface. At this time, the two conductive contacts can be electrically connected through the aqueous solution, which connects the power supply circuit of the buzzer. The buzzer will then remind the tester that the test sample has reached the impermeability limit. The above technical solution can quantify the judgment standard of the impermeability limit, is not affected by the subjective judgment of the tester, and can significantly reduce the error of the test results. At the same time, the tester can focus on water pressure control during the test and does not need to spend a lot of energy observing whether water seepage occurs.

[0017] The water-absorbing conductive ring can further improve the conductivity of the water film that seeps out of the test sample. When a water film appears on the surface of the test sample, it will be absorbed by the water-absorbing conductive ring, which will then dissolve the electrolyte material in it to form a salt solution, significantly improving the conductivity of the water film. This avoids the situation where the conductive contacts cannot be connected in time due to the poor conductivity of the water film after it appears, thus preventing the situation from being detected in time.

[0026] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0027] like Figure 1 - Figure 3 As shown in the figure, this embodiment provides a test mechanism for the impermeability of basalt chip waterproof mortar, including a test platform 1, on which a hydraulic mechanism 2 is installed and a water supply mechanism is provided inside; a placement boss 3 on which a test sample 5 to be tested is placed; a sealing cover 4, which is installed at the bottom of the hydraulic mechanism 2 and located directly above the placement boss 3, and can completely cover the test sample 5 when it is lowered; and a permeability monitoring mechanism 6, which is set in the sealing cover 4. The permeability monitoring mechanism 6 includes a buffer frame 61 fixedly connected to the sealing cover 4, and a bottom cylinder 62 installed at the bottom of the buffer frame 61. Two symmetrically arranged conductive contacts 6 are installed on the bottom cylinder 62. 3. In addition, a buzzer 64 is installed on the sealed cover 4. Two conductive contacts 63 form a switch connected in series in the power supply circuit of the buzzer 64. When the test sample 5 shows signs of seepage, the conductive contacts 63 are connected through the seepage solution, which in turn connects the power supply circuit of the buzzer 64. The buzzer 64 then alerts the test personnel that the test sample 5 has reached the seepage resistance limit. The above technical solution can quantify the judgment criteria of the seepage resistance limit, is not affected by the subjective judgment of the test personnel, and can significantly reduce the error of the test results. At the same time, the test personnel can focus on water pressure control during the test and do not need to spend a lot of energy observing whether seepage occurs.

[0028] To further improve the conductivity of the water film seeping from the test sample 5, a water-absorbing conductive ring 66 is detachably installed on the lower end face of the bottom cylinder 62. This ring is made of porous absorbent paper and filled with water-soluble electrolyte filler. When a water film seeps onto the surface of the test sample 5, it absorbs the water, dissolving the electrolyte material to form a salt solution. This significantly improves the conductivity of the water film and prevents the conductive contact 63 from failing to connect promptly due to poor conductivity after the water film has seeped in, thus avoiding the situation where it cannot be detected in time. Figure 3As shown; in addition, a number of retaining pins 621 arranged in a circumferential array are fixedly provided on the lower end face of the bottom cylinder 62. The water-absorbing conductive ring 66 has retaining holes 661 corresponding to the retaining pins 621, and the water-absorbing conductive ring 66 has contact through holes 662 corresponding to the conductive contacts 63. The retaining pins 621 and retaining holes 661 can be used to quickly install and remove the water-absorbing conductive ring 66, which is convenient for it to be quickly replaced after a test. Figure 5 As shown.

[0029] A power supply battery 65 is installed inside the buffer frame 61. Its positive terminal is electrically connected to the positive terminal of the buzzer 64 via a wire 67, and its negative terminal is electrically connected to one of the conductive contacts 63 via a wire 67. The other conductive contact 63 is electrically connected to the negative terminal of the buzzer 64 via a wire 67. When the two conductive contacts 63 are connected via the water film, the power supply battery 65 can supply power to the buzzer 64, enabling it to operate and sound an alarm. Figure 4 As shown.

[0030] The buffer frame 61 includes several guide rods 611 arranged in a circumferential array. Anti-detachment end plates 612 are fixedly connected to the bottom of each rod, and a movable plate 613 is slidably mounted on it. Furthermore, a buffer spring 614 is sleeved on each guide rod 611. When the bottom cylinder 62 moves to contact the upper surface of the test sample 5, as the sealing cover 4 continues to press down, the movable plate 613 will overcome the thrust of the buffer spring 614 and move upward, preventing damage to the bottom cylinder 62 due to the continuous downward movement of the sealing cover 4. Simultaneously, the buffer spring 614 can continuously apply thrust, ensuring a tight fit between the bottom cylinder 62 and the upper surface of the test sample 5. Figure 3 As shown.

[0031] like Figure 2 As shown, a support ring 31 is fixedly installed at the top of the placement boss 3, and a sealing gasket 32 ​​is fitted on it. In addition, a water inlet 33 with a sealed connection is provided inside the placement boss 3. The above structure can achieve a sealed connection between the support ring 31 and the test sample block 5 through the sealing gasket 32, preventing water from seeping out through the gaps. At the same time, the sealing cover 4 includes a cover 41, and a force transmission frame 42 connected to the hydraulic mechanism 2 is fixedly installed at the top of the cover 41. An inner sealing rubber cylinder 43 is fixedly installed on the inner wall of the cover 41. The above structure can achieve a sealed connection between the cover 41 and the test sample block 5 through the inner sealing rubber cylinder 43, preventing water from seeping out through the gaps.

[0032] The water supply mechanism includes an integrated pump and tank mechanism 7, which consists of a water tank and an internally installed pump body. The pump body's output end is sealed to a water supply pipe 71 connected to the water inlet component 33. A return pipe 72, leading to the water tank, is sealed to the water supply pipe 71. Both the water supply pipe 71 and the return pipe 72 are equipped with check valves 73. During water supply, the check valve 73 on the water supply pipe 71 opens, and the check valve 73 on the return pipe 72 closes. The pump body pumps water through the water supply pipe 71 to the water inlet component 33 for seepage resistance testing. After the test is completed, the check valves 73 reverse their opening and closing states, allowing water to flow through the return pipe 72 into the water tank. Figure 6 As shown.

[0033] The working principle and usage process of this utility model:

[0034] During the test, the one-way valve 73 on the water supply pipe 71 is opened and the one-way valve 73 on the return pipe 72 is closed. The pump body pumps water through the water supply pipe 71 to the water inlet 33 for seepage resistance testing. After the test is completed, the opening and closing states of the one-way valve 73 are reversed, so that the water flows through the return pipe 72 into the water tank.

[0035] When test sample 5 reaches its impermeability limit, a layer of water film will seep out from its upper surface. At this time, the two conductive contacts 63 can achieve electrical connection through the aqueous solution, connecting the power supply circuit of buzzer 64. Buzzer 64 will then alert the tester that test sample 5 has reached its impermeability limit. The above technical solution can quantify the judgment criteria of the impermeability limit, and is not affected by the subjective judgment of the tester. It can significantly reduce the error of the test results. At the same time, the tester can focus on water pressure control during the test and does not need to spend a lot of energy observing whether water seepage occurs.

[0036] The water-absorbing conductive ring 66 can further improve the conductivity of the water film seeping out of the test sample 5. When a water film seeps out on the surface of the test sample 5, it will be absorbed by the water-absorbing conductive ring 66, which will then dissolve the electrolyte material in it to form a salt solution, significantly improving the conductivity of the water film. This avoids the situation where the conductive contact 63 cannot be connected in time due to the poor conductivity of the water film and thus cannot be detected in time.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
