Description

Technical Field

[0001] This application relates to the technical field of waterproof coatings, and particularly to a detector for the penetration performance of waterproof coatings. Background Art

[0002] In the field of building materials, waterproof materials are commonly used in roof leakage prevention operations. Therefore, in order to ensure the waterproof and penetration ability of waterproof materials, the performance detection of waterproof coatings is a key technical task. Especially for the penetration performance of waterproof coatings, it is one of the important indicators to evaluate the waterproof effect of coatings. Traditional penetration performance detection methods, such as coating specimens, water absorption tests, and water penetration tests, although they can provide some useful information, still have some limitations in practical applications. For example, traditional water absorption tests and water penetration tests often cannot accurately reflect the performance of coatings in complex environments or actual application scenarios, and it is difficult to simulate the actual penetration situation of coatings during use.

[0003] For example, a waterproof performance detection device for a waterproof coating with the publication number CN218067567U can achieve an adjustable detection angle of 0 - 45° through the provided rotation adjustment mechanism, can simulate the stress state of the waterproof layer at different parts of the building, provide an adjustable water pressure of 0.5 - 3 MPa through a dynamic spraying system, cooperate with a circulating water supply to achieve continuous impact detection, and an embedded humidity sensor group can collect penetration data in real time, and cooperate with a data recorder to generate a waterproof performance attenuation curve, so as to realize the impact detection of the waterproof coating by the inclined water flow and improve the detection accuracy of waterproof materials.

[0004] Although the above-mentioned prior art can adjust the water pressure to conduct continuous impact detection on the waterproof layer, there are still some defects: 1. The above-mentioned prior art only uses a grid plate to replace traditional building materials, then applies the corresponding waterproof material on its surface, and then conducts a leakage test through water flow to evaluate the effect. However, the grid plate material used is usually a lightweight or lightweight composite material, rather than common actual building materials such as concrete. This results in the detection results not truly reflecting the performance of waterproof materials in the actual use environment. Especially in large-scale engineering construction, structures such as the ground are often composed of concrete. Therefore, when using a grid plate for waterproof detection, the test results obtained lack representativeness and are difficult to accurately predict the performance of materials in actual projects.

[0005] 2. The above-mentioned prior art conducts pressure detection by storing static water on the waterproof material. This method indeed has certain limitations. In the actual use environment, the forms of rainwater acting on building materials are diverse, including flowing, accumulating, etc. Therefore, only detecting by storing water in a static manner may not comprehensively and truly reflect the performance in actual use. The results obtained by such a detection method may be too single and unrepresentative, and cannot accurately predict the actual performance of waterproof materials in complex environments.

[0006] Based on this, under the statement of the above viewpoints, there is still room for improvement in the existing technology for detecting waterproof materials. Summary of the Invention

Moreover, the used concrete slab can further simulate the actual building materials.

Then, when the concrete slab contacts the bottom of the water storage cylinder, the circular protrusion and the circular groove cooperate with each other to increase the sealing performance of the contact part between the concrete slab and the bottom of the water storage cylinder. In addition, when the sealing block drives the linkage rod to move downward, it drives the circular block to extrude and block the contact part between the concrete slab and the bottom of the water storage cylinder, further ensuring the sealing performance of the contact part between the concrete slab and the bottom of the water storage cylinder.

Detailed implementation manners

[0037] The following further describes the present application in detail Figures 1 to 13 in conjunction with the accompanying drawings.

[0038] An embodiment of the present application discloses a waterproof coating penetration performance detector, which can simulate the working conditions of waterproof materials on a concrete base surface in two scenarios of ponding and precipitation by integrating a water storage cavity and a multi-modal control system, ensuring the accuracy of the detection data and enabling a more comprehensive evaluation of the performance of waterproof materials.

[0039] Embodiment 1: Referring to Figures 1 to 3 , a waterproof coating penetration performance detector includes two symmetrically arranged support frames 1. A vertically penetrating water storage cylinder 2 is jointly installed between the two support frames 1. A plurality of leakage holes 21 that are circumferentially uniformly distributed and controlled to open and close are formed at the bottom of the circumferential surface of the water storage cylinder 2. A sprinkler mechanism 3 is further provided inside the water storage cylinder 2. An annular frame 4 for lifting a concrete slab is jointly installed between the two support frames 1. A glue application mechanism 5 is jointly installed on the sides of the two support frames 1. The glue application mechanism 5 includes: The moving component 51 is arranged on the two support frames 1.

[0040] The glue outlet pipe 52 is rotatably arranged on the moving component 51. A plurality of glue outlet holes 53 are evenly arranged at the bottom of the glue outlet pipe 52 along its length direction. Scrapers 54 are symmetrically installed on both sides of the glue outlet pipe 52, and the glue outlet pipe 52 moves up and down during rotation.

[0041] Refer to Figure 4 , wherein the diameters of the glue outlet holes 53 at both ends of the glue outlet pipe 52 are larger than those of the remaining glue outlet holes 53. Inclined slopes are arranged at both ends of the scraper 54 and are matched with the glue outlet holes 53 at both ends of the glue outlet pipe 52.

[0042] A cleaning component 55 for cleaning the surface of the concrete slab is further installed on the moving component 51 to ensure that the waterproof material is separated from the concrete slab during the gluing process.

[0043] During the cooperation of the water storage cylinder 2 with the concrete slab, the water leakage hole 21 is closed and colored water is poured into the interior of the water storage cylinder 2, so as to simulate the situation of water accumulation on the concrete slab; the water leakage hole 21 is opened and water is sprinkled on the concrete slab through the sprinkling mechanism 3, and the excess water leaks out through the water leakage hole 21, so as to simulate the situation that the concrete has no water accumulation and the waterproof material is affected by water in rainy days. Moreover, the used concrete slab can further simulate the actual building materials. Thus, through the integrated water storage cavity and the multi-modal control system, the double-condition simulation detection of the waterproof material on the concrete base surface in the water accumulation / precipitation scenarios is realized, ensuring the accuracy of the detection data.

[0044] Refer to Figure 3 , the moving component 51 includes an extension frame 511 installed on the support frame 1. A moving frame 512 is slidably arranged on the extension frame 511 together. Fixed frames 513 are symmetrically installed on the moving frame 512 along its length direction. A first fixed machine frame 514 is jointly installed between the fixed frames 513. A rotating shaft 515 is rotatably installed on the first fixed machine frame 514 through a bearing, and the glue outlet pipe 52 is installed at the bottom of the rotating shaft 515.

[0045] Refer to Figure 6 , the cleaning component 55 includes a second fixed machine frame 551 arranged between the two fixed frames 513. A rotating shaft 552 is installed on the second fixed machine frame 551 through a bearing. A cleaning brush 553 is installed at the bottom of the rotating shaft 552. Air blowing pipes 554 are installed on both sides of the cleaning brush 553. A cleaning part 56 is further installed on the rotating shaft 552.

[0046] Refer to Figure 10 , electric sliders 11 are arranged on the opposite surfaces of the support frame 1, and the annular frame 4 is installed on the two electric sliders 11 through support protrusions.

[0047] It should be noted that the annular frame 4 and the water storage cylinder 2 are coaxial. During specific operation, a substrate to be coated with waterproof material (such as a circular concrete slab) is placed inside the annular frame 4. At this time, the height of the annular frame 4 with the concrete slab is lower than the height of the moving component 51, and the height of the cleaning brush 553 is higher than the height of the concrete slab. After the placement of the concrete slab is completed, an external driving force (such as a cylinder, not shown in the figure) drives the moving frame 512 to move. During the movement of the moving frame 512, the fixed frame 513 synchronously drives the second fixed frame 551 to move. During the movement of the second fixed frame 551, the rotating shaft 552 is synchronously driven to move, and the rotating shaft 552 is made coaxial with the concrete slab.

[0048] At this time, the electric slider 11 is started. During the movement of the electric slider 11, the annular frame 4 is synchronously driven through the support protrusion. During the movement of the annular frame 4, the concrete slab is synchronously driven to move upward so that the surface of the concrete slab is in contact with the cleaning brush 553. Then, the air duct 554 is connected to an external air pump (not shown in the figure). At this time, gas is pumped into the air duct 554 through the air pump, and the gas flows out through the air duct 554.

[0049] At this time, an external driving motor (not shown in the figure) is used to drive the rotating shaft 552 to rotate. During the rotation of the rotating shaft 552, the cleaning brush 553 is driven to rotate circumferentially around the rotating shaft 552. During the circumferential rotation of the cleaning brush 553, the dust on the surface of the concrete slab can be cleaned. During the rotation of the cleaning brush 553, the gas inside the air duct 554 flows synchronously to form an air current. The air current can blow the cleaned dust to the periphery of the concrete slab during the rotation of the cleaning brush 553, avoiding the possibility of the dust still accumulating on the concrete slab.

[0050] Furthermore, before applying the waterproof material on the surface of the concrete slab, the surface of the concrete slab is cleaned, thereby ensuring the cleanliness of the surface of the concrete slab and avoiding the risk that the waterproof material does not fit tightly with the surface of the concrete slab or even falls off due to the influence of dust and the like after being applied.

[0051] Refer to Figure 6 and Figure 7 , in order to clean the stubborn impurities on the concrete slab, the rotating coupling shaft 561 provided by the present invention can drive the hard bristles 562 to provide an external force to the stubborn impurities on the concrete slab, so that the stubborn impurities can fall off from the concrete slab. Specifically, the cleaning part 56 includes a rotating coupling shaft 561 rotatably installed through a bearing on the rotating shaft 552. The circumferential surface of the rotating coupling shaft 561 is uniformly provided with hard bristles 562. An annular rack plate 563 is installed on the second fixed frame 551, and a bevel gear 564 meshing with the annular rack plate 563 is installed on the rotating coupling shaft 561.

[0052] It should be noted that the height of the hard bristles 562 is the same as that of the cleaning brush 553. During specific operation, when the rotating shaft 552 rotates, it drives the rotating connecting shaft 561 to rotate circumferentially synchronously. During the circumferential rotation of the rotating connecting shaft 561, it rotates self-synchronously through the meshing of the bevel gear 564 and the annular rack plate 563. During the self-rotation of the rotating connecting shaft 561, it drives the hard bristles 562 to rotate circumferentially around the rotating connecting shaft 561 synchronously. During the circumferential rotation of the hard bristles 562, an external force can be provided to the stubborn impurities on the concrete slab without external force, so that the stubborn impurities can be separated from the concrete slab, further improving the cleanliness of the concrete slab surface. The stubborn impurities cleaned can be blown to the periphery of the concrete slab by the cooperation of the cleaning brush 553 and the air duct 554.

[0053] After the surface of the concrete slab is cleaned, start the electric slider 11 to drive the concrete slab to move down a certain distance through the cooperation of the support protrusion and the annular frame 4, so that there is a certain distance between the concrete slab, the glue outlet pipe 52 and the cleaning brush 553, avoiding the collision between the glue outlet pipe 52 and the concrete slab when the fixed frame one 514 moves subsequently. Through external drive, the moving frame 512 continues to move. During the movement of the moving frame 512, it drives the fixed frame one 514 to move through the fixed frame 513, so that the rotating shaft 515 and the concrete slab are coaxial. At this time, the fixed frame 513 drives the rotating shaft 552 to move out of the concrete slab synchronously through the fixed frame two 551.

[0054] Then start the electric slider 11 to drive the concrete slab to move up a certain distance through the cooperation of the support protrusion and the annular frame 4 and make the bottom of the glue outlet pipe 52 close to the concrete slab.

[0055] Refer to Figure 5 , the rotating shaft 515 is composed of a rotating section installed on the fixed frame one 514 and a telescopic section arranged at the bottom of the rotating section, and the glue outlet pipe 52 is installed at the bottom of the telescopic section. A lifting plate 516 is installed on the rotating section of the rotating shaft 515 by means of threaded connection. The bottom of the fixed frame one 514 is symmetrically installed with limiting rods 517 along its length direction, and the end of the limiting rod 517 away from the fixed frame one 514 penetrates and is slidably arranged on the lifting plate 516. The telescopic section of the rotating shaft 515 is rotationally installed with a linkage disc 518 through a bearing, and fixing rods 519 symmetrically distributed along the length direction of the fixed frame one 514 are jointly installed between the linkage disc 518 and the lifting plate 516.

[0056] Wherein, the telescopic section of the rotating shaft 515 is limited and slidably arranged on the rotating section of the rotating shaft 515, that is, during the rotation of the rotating section of the rotating shaft 515, the telescopic section of the rotating shaft 515 can be driven to rotate synchronously. And waterproof material is pumped into the inside of the glue outlet pipe 52 through an existing pump body (not shown in the figure). It should be noted that the waterproof material involved in the present invention has certain elasticity after solidification. During specific operation, after the bottom of the glue outlet pipe 52 approaches the concrete slab, the rotating shaft 515 is driven to rotate by an external driving motor (not shown in the figure). During the rotation of the rotating shaft 515, the rotating section drives the telescopic section of the rotating shaft 515 to rotate synchronously. During the rotation of the telescopic section of the rotating shaft 515, the glue outlet pipe 52 is driven to rotate circumferentially. During the rotation of the glue outlet pipe 52, the waterproof material can be smeared on the concrete slab. At this time, the glue outlet pipe 52 drives the scraping plate 54 to evenly brush the waterproof material.

[0057] As the number of rotation circles of the rotating shaft 515 increases, during the rotation of the rotating shaft 515, the lifting plate 516 has a tendency to rotate synchronously through a threaded connection method. And due to the limitation of the limiting rod 517, the lifting plate 516 does not rotate with the rotating shaft 515 but moves upward along the rotating section of the rotating shaft 515. During the upward movement of the lifting plate 516, the linkage disc 518 is driven to move upward synchronously through the fixing rod 519. During the upward movement of the linkage disc 518, the telescopic section of the rotating shaft 515 is driven to move upward synchronously. During the upward movement of the telescopic section of the rotating shaft 515, the glue outlet pipe 52 is driven to move upward synchronously.

[0058] Furthermore, as the number of rotation circles of the rotating shaft 515 increases, the glue outlet pipe 52 moves upward a certain distance synchronously. Then, the distance that the glue outlet pipe 52 moves upward can make way for the smeared waterproof material, avoiding the possibility that as the waterproof material flows out, the thickness of the waterproof material layer increases and collides with the glue outlet pipe 52 and the scraping plate 54, resulting in a constant thickness of the waterproof material layer (this fixed distance is also the distance between the glue outlet pipe 52 and the concrete slab without making way). At the same time, it reduces the possibility of blockage at the bottom of the glue outlet pipe 52 and ensures the smearing effect of the waterproof material on the concrete slab.

[0059] Therefore, as the waterproof material accumulates and thickens on the concrete slab, the glue outlet pipe 52 gradually lifts according to the preset lead parameter, always maintaining the critical contact state between the scraping plate 54 and the uncured material layer, avoiding interference or blockage of the discharge pipe caused by material accumulation.

[0060] After the waterproof material on the concrete slab is painted, push the moving frame 512 to reset. At this time, wait for the waterproof material on the concrete slab to dry and solidify. If the detection task is urgent, an existing dryer can be used to dry the waterproof material on the concrete slab to accelerate the solidification of the waterproof material on the concrete slab.

[0061] After the waterproof material on the concrete slab solidifies, start the electric slider 11. The electric slider 11 drives the concrete slab to move upward through the cooperation of the supporting protrusions and the annular frame 4 and fits with the bottom of the water storage cylinder 2.

[0062] Referring to Figure 8 and Figure 9 , the water sprinkling mechanism 3 includes a horizontal frame 31 installed inside the water storage cylinder 2. A rotating rod 32 is rotatably installed through the horizontal frame 31 by means of bearings. A spray pipe 33 is installed at the bottom of the rotating rod 32. A plurality of spray holes 34 are evenly formed in the bottom of the spray pipe 33 along the length direction thereof.

[0063] It should be noted that the water droplets or water flows inside the water storage cylinder 2 are all colored. Then, when observing whether the bottom of the concrete slab is waterproof subsequently, it is only necessary to observe whether there is an area with the same color as the water at the bottom of the concrete slab. If there is, it means that the waterproof effect of the concrete slab is poor; otherwise, the waterproof effect is good. And according to the colored area at the bottom of the concrete, the specific leakage position at the bottom of the concrete can be judged. Then, the spray pipe 33 is connected in a through manner with the water outlet of an existing water pump (not shown in the figure). During specific operation, when simulating the scenario where there is no water accumulation on the concrete slab, the rotating rod 32 is driven to rotate by an external driving motor (not shown in the figure). During the rotation of the rotating rod 32, the spray pipe 33 is driven to rotate around the rotating rod 32. During the rotation of the spray rod, the existing water pump pumps water into the spray pipe 33. The water flows through the spray holes 34 and falls on the concrete slab. The water droplets falling on the concrete slab accumulate and flow out through the leakage holes 21. Thus, the scenario when it is raining and there is no water accumulation on the concrete slab can be simulated. Then, observe whether there is an area with the same color as the water at the bottom of the concrete slab. If there is, it means that the waterproof effect of the concrete slab is poor; otherwise, the waterproof effect is good.

[0064] Referring to Figure 10 and Figure 11 , a sealing block 211 is arranged inside the leakage hole 21. An annular plate 212 is slidably arranged on the circumferential surface of the water storage cylinder 2. An elastic telescopic rod 213 for resetting the annular plate 212 is commonly installed between the annular plate 212 and the support frame 1. A linkage rod 214 corresponding to the sealing block 211 one by one is arranged at the bottom of the annular plate 212. A guiding inclined surface matched with the linkage rod 214 is arranged on the sealing block 211. A rectangular protrusion is arranged at the bottom of the sealing block 211. A return spring rod 215 is commonly installed between the rectangular protrusion and the water storage cylinder 2.

[0065] During specific operation, when it is necessary to simulate the scenario of water accumulation on the concrete slab, an external force (such as a cylinder) is used to press the annular plate 212 downward. During the movement of the annular plate 212, the linkage rod 214 is driven to move synchronously. At this time, the elastic telescopic rod 213 is stretched. During the movement of the linkage rod 214, it cooperates with the guiding inclined plane to drive the sealing block 211 to move towards the inside of the water leakage hole 21. At this time, the return spring rod 215 is compressed, and the water leakage hole 21 is blocked by the sealing block 211. Thus, when the spray pipe 33 sprays water droplets, the water droplets accumulate on the concrete slab and are stored inside the water storage cylinder 2, thereby simulating the scenario of water accumulation on the concrete slab during rain. Then, observe whether there is an area with the same color as the water at the bottom of the concrete slab. If there is, it indicates that the waterproof effect of the concrete slab is poor; otherwise, the waterproof effect is good.

[0066] In addition, scale lines are provided inside the water storage cylinder 2. Thus, according to the scale indication, the water volume inside the water storage cylinder 2 can be judged. The deeper the water inside the water storage cylinder 2, the greater the pressure on the concrete slab, thereby simulating the waterproof effect of the waterproof material on the concrete slab under different pressures.

[0067] Among them, the elastic telescopic rod 213 is used to reset the annular plate 212, and the return spring rod 215 is used to reset the sealing block 211.

[0068] Refer to Figure 9 , in order to simulate environments with different rainfall amounts, the spray pipe 33 provided by the present invention can control the size of the sprayed water flow. Specifically, a slide plate 331 that corresponds to the spray holes 34 one by one and adjusts the size of the spray holes 34 is slidably arranged at the bottom of the spray pipe 33. The slide plates 331 are connected to each other through connecting protrusions. A fixed protrusion is installed at one end of the spray pipe 33, and a linkage protrusion is provided on the slide plate 331 close to the fixed protrusion. A return spring rod 332 is jointly installed between the linkage protrusion and the connecting protrusion.

[0069] During specific operation, when a larger water flow is required, at this time, the rotation speed of the rotating rod 32 is increased. Thus, during the rotation of the rotating rod 32, the centrifugal force on the slide plate 331 is larger, and the slide plate 331 moves. At this time, the slide plate 331 drives the return spring rod 332 to stretch through the cooperation between the connecting protrusion and the linkage protrusion, and the spray hole 34 becomes larger at this time. Thus, the size of the water flow sprayed by the spray pipe 33 can be changed, further simulating the environment during the use of the waterproof material and making the detection data more representative.

[0070] Embodiment 2: Refer to Figure 12 and Figure 13, on the basis of the first embodiment, an annular groove 22 is formed at the bottom of the water storage cylinder 2, and an annular block 23 with automatic reset is arranged inside the annular groove 22. A linkage rod 24 corresponding to each water leakage hole 21 is arranged on the annular block 23, and a guiding inclined surface matching with the linkage rod 24 is formed on the sealing block 211.

[0071] It should be noted that the waterproof material involved in the present invention has a certain elasticity when solidifying. During the circumferential rotation of the glue outlet pipe 52, the two glue outlet holes 53 at its edge can form an annular protrusion on the concrete slab. Then, when the concrete slab contacts the bottom of the water storage cylinder 2, the annular protrusion and the annular groove cooperate with each other to increase the sealing performance of the contact part between the concrete slab and the bottom of the water storage cylinder 2. In addition, when the sealing block 211 drives the linkage rod 24 to move downward, it drives the annular block 23 to extrude and seal the contact part between the concrete slab and the bottom of the water storage cylinder 2, further ensuring the sealing performance of the contact part between the concrete slab and the bottom of the water storage cylinder 2.

[0072] In addition, a connecting spring rod is jointly installed between the annular block 23 and the annular groove 22 for the reset of the annular block 23. During specific operation, the formed annular protrusion and the annular groove 22 cooperate with each other. When the sealing block 211 moves into the water leakage hole 21, the guiding inclined surface on the sealing block 211 and the linkage rod 24 cooperate with each other to drive the annular block 23 to move downward. During the downward movement of the annular block 23, it extrudes the annular protrusion and causes the annular protrusion to deform. Then, the deformation of the annular protrusion can fill the entire annular groove 22, so that the cooperative effect of the annular groove and the annular block increases the sealing performance of the contact part between the concrete slab and the bottom of the water storage cylinder. This cooperative sealing reduces water leakage and ensures the accuracy of detection data.

[0073] The implementation principle of the present invention is as follows: (1): During the rotation of the rotating shaft 552, the cleaning brush 553 is driven to rotate circumferentially around the rotating shaft 552. During the circumferential rotation of the cleaning brush 553, the dust on the surface of the concrete slab can be cleaned. During the rotation of the cleaning brush 553, the gas inside the air duct 554 flows synchronously to form an air flow, and the air flow can blow the cleaned dust to the periphery of the concrete slab during the rotation of the cleaning brush 553.

[0074] (2): During the movement of the moving frame 512, the fixed frame 513 drives the first fixed machine frame 514 to move, so that the rotating shaft 515 and the concrete slab are coaxial. During the rotation of the rotating shaft 515, the rotating section drives the telescopic section of the rotating shaft 515 to rotate synchronously. During the rotation of the telescopic section of the rotating shaft 515, the glue outlet pipe 52 is driven to rotate circumferentially. During the rotation of the glue outlet pipe 52, the waterproof material can be applied to the concrete slab, and at this time, the glue outlet pipe 52 drives the scraper 54 to evenly apply the waterproof material.

[0075] (3): When simulating the scenario where there is no water accumulation on the simulated concrete slab, an external driving motor (not shown in the figure) drives the rotating rod 32 to rotate. During the rotation of the rotating rod 32, the spray pipe 33 is driven to rotate around the rotating rod 32. During the rotation of the spray rod, the existing water pump pumps water into the spray pipe 33. The water flows through the spray holes 34 and falls on the concrete slab. The water droplets falling on the concrete slab accumulate and flow out through the water leakage holes 21, thereby simulating the scenario where there is no water accumulation on the concrete slab during rain, and then observing whether there is an area with the same color as the water at the bottom of the concrete slab.

[0076] (4): When it is necessary to simulate the scenario where there is water accumulation on the concrete slab, an external force (such as a cylinder) is used to press down the annular plate 212. During the movement of the annular plate 212, the linkage rod 214 is driven to move synchronously. At this time, the elastic telescopic rod 213 is stretched. During the movement of the linkage rod 214, it cooperates with the guiding inclined plane to drive the sealing block 211 to move into the water leakage hole 21. At this time, the return spring rod 215 is compressed, and the water leakage hole 21 is blocked by the sealing block 211. Therefore, when the spray pipe 33 sprays water droplets, the water droplets accumulate on the concrete slab and are stored inside the water storage cylinder 2, thereby simulating the scenario where it is raining and there is water accumulation on the concrete slab, and then observing whether there is an area with the same color as the water at the bottom of the concrete slab.
