Description

TECHNICAL FIELD

[0001] The application relates to the technical field of waterproof coating, in particular to a waterproof coating permeability detector. BACKGROUND

[0002] In the field of building materials, waterproof materials are often used in roof leakage prevention operations, so in order to ensure the waterproof permeability of waterproof materials, performance detection of waterproof coating is a key technical work. Especially for the permeability of waterproof coating, it is one of the important indicators for evaluating the waterproof effect of the coating. Although the traditional permeability detection methods such as coating sample, water absorption test and water permeation test can provide some useful information, there are still some limitations in actual application. For example, the traditional water absorption test and water permeation test often cannot accurately reflect the performance of the coating in complex environments or actual application scenarios, and it is difficult to simulate the actual permeation of the coating in the use process.

[0003] For example, a waterproof performance detection device for waterproof coating with the publication number CN218067567U can realize 0-45° adjustable detection angle through the provided rotary adjusting mechanism, can simulate the stress state of the waterproof layer of different parts of the building, provides 0.5-3MPa adjustable water pressure through the dynamic spraying system, realizes continuous impact detection in cooperation with the circulating water supply, realizes real-time collection of permeation data through the embedded humidity sensor group, generates the waterproof performance attenuation curve in cooperation with the data recorder, so as to realize the impact detection of the water flow on the waterproof coating at the inclined angle, and improve the detection precision of the waterproof material.

[0004] The above-mentioned prior art can adjust the water pressure to continuously impact the waterproof layer for detection, but still has some defects: 1. The above-mentioned prior art only uses a grid plate to replace the traditional building material, then applies the corresponding waterproof material on the surface of the grid plate, and then performs a leakage test through the water flow to evaluate the effect. However, the grid plate material used is usually a lightweight or lightweight composite material, rather than the actual building material such as concrete, which leads to the fact that the detection result cannot truly reflect the performance of the waterproof material in the actual use environment. Especially in large-scale engineering construction, the ground structure is often composed of concrete, so when the waterproof detection is performed using the grid plate, the test result obtained lacks representativeness and it is difficult to accurately predict the performance of the material in the actual engineering.

[0005] 2. The above-mentioned prior art detects the pressure by storing static water on the waterproof material. This method indeed has certain limitations. In the actual use environment, rainwater acts on the building material in various forms, including flowing and accumulating, so the detection by only storing water in a static way may not comprehensively and truly reflect the performance in the actual use condition. The result obtained by such a detection method may be too single and not representative, and cannot accurately predict the actual performance of the waterproof material in a complex environment.

[0006] Based on this, and according to the above viewpoints, there is still room for improvement in the existing technology for testing waterproof materials. Summary of the Invention

The leaking holes are opened and water is sprinkled onto the concrete slab through a sprinkler mechanism. Excess water leaks out through the leaking holes, simulating a situation where there is no water accumulation in the concrete and the waterproof material is exposed to water during rainy days.

[0042] With reference to Figures 1 to 3 The waterproof coating permeability detector comprises two symmetrically arranged supporting frames 1, a water storage cylinder 2 penetrating from top to bottom is arranged between the two supporting frames 1, a plurality of water leakage holes 21 that are uniformly distributed in the circumferential direction and are controlled to be opened and closed are arranged at the bottom of the circumferential surface of the water storage cylinder 2, a water spraying mechanism 3 is further arranged in the water storage cylinder 2, an annular frame 4 for lifting a concrete plate is arranged between the two supporting frames 1, and a glue applying mechanism 5 is arranged at the side edges of the two supporting frames 1.

[0044] The glue outlet pipe 52 is rotatably arranged on the moving assembly 51, a plurality of glue outlet holes 53 are uniformly arranged on the length direction of the bottom of the glue outlet pipe 52, scraper plates 54 are symmetrically arranged on the two sides of the glue outlet pipe 52, and the glue outlet pipe 52 moves up and down during rotation.

[0045] With reference to Figure 4 The diameters of the glue outlet holes 53 at the two ends of the glue outlet pipe 52 are greater than the diameters of the remaining glue outlet holes 53, and the scraper plates 54 are provided with inclined surfaces at the two ends, which are matched with the glue outlet holes 53 at the two ends of the glue outlet pipe 52.

[0046] The cleaning assembly 55 for cleaning the surface of the concrete plate is further arranged on the moving assembly 51, so as to ensure that the waterproof material is separated from the concrete plate during the glue applying process.

[0047] During cooperation of the water storage cylinder 2 and the concrete plate, the water leakage holes 21 are closed, and colored water is poured into the water storage cylinder 2, so as to simulate the situation that there is accumulated water on the concrete plate; the water leakage holes 21 are opened, and the water spraying mechanism 3 sprays water on the concrete plate, and the excess water leaks out through the water leakage holes 21, so as to simulate the situation that there is no accumulated water on the concrete and the waterproof material is affected by water in rainy days, and the used concrete plate can further simulate the actual use material of the building, so as to realize double working condition simulation detection of the waterproof material on the concrete base surface in the accumulated water / rainfall scene through the integrated water storage cavity and the multi-mode control system, and ensure the accuracy of the detection data.

[0048] With reference to Figure 3 The moving assembly 51 comprises an extension frame 511 arranged on the supporting frame 1, a moving frame 512 is slidably arranged on the extension frame 511, fixed frames 513 are symmetrically arranged on the moving frame 512 along the length direction thereof, a fixed rack 514 is arranged between the fixed frames 513, a rotating shaft 515 is rotatably arranged on the fixed rack 514 through a bearing, and the glue outlet pipe 52 is arranged at the bottom of the rotating shaft 515.

[0049] With reference toFigure 6 The cleaning assembly 55 comprises a fixed frame two 551 arranged between the two fixed frames 513, a rotating shaft 552 is arranged on the fixed frame two 551 through bearings, a cleaning brush 553 is arranged at the bottom of the rotating shaft 552, air blowing pipes 554 are arranged on both sides of the cleaning brush 553, and the cleaning part 56 is further arranged on the rotating shaft 552.

[0050] With reference to Figure 10 The opposite surface of the support frame 1 is provided with electric sliding blocks 11, and the annular frame 4 is arranged on the two electric sliding blocks 11 through support protrusions.

[0051] It should be noted that the annular frame 4 is coaxial with the water storage cylinder 2, and in the specific working process, the base material (for example, a concrete plate with a circular structure) to be coated with waterproof material is placed in the annular frame 4, at this time, the height of the annular frame 4 with the concrete plate is lower than the height of the moving assembly 51, and the height of the cleaning brush 553 is higher than the height of the concrete plate, when the placement of the concrete plate is completed, the moving frame 512 is driven to move through an external driving force (a gas cylinder, etc., not shown in the figure), the moving frame 512 moves in the process to synchronously drive the fixed frame 513 to move, the fixed frame two 551 moves in the process to synchronously drive the rotating shaft 552 to move, and the rotating shaft 552 is coaxial with the concrete plate.

[0052] At this time, the electric sliding blocks 11 are started, the electric sliding blocks 11 move in the process to synchronously drive the annular frame 4 to move through the support protrusions, the annular frame 4 moves in the process to synchronously drive the concrete plate to move upwards and make the surface of the concrete plate abut against the cleaning brush 553, and then the air blowing pipes 554 are connected with an external air pump (not shown in the figure), at this time, the air pump is used to pump air into the air blowing pipes 554, and the air flows out through the air blowing pipes 554.

[0053] At this time, the rotating shaft 552 is driven to rotate through an external driving motor (not shown in the figure), the rotating shaft 552 rotates in the process to drive the cleaning brush 553 to rotate circumferentially around the rotating shaft 552, the cleaning brush 553 rotates circumferentially in the process to clean the dust on the surface of the concrete plate, and the air in the air blowing pipes 554 flows synchronously in the process of the rotation of the cleaning brush 553 to form an air flow, which can blow the cleaned dust to the periphery of the concrete plate in the process of the rotation of the cleaning brush 553, so as to avoid the possibility that the dust is still gathered on the concrete plate.

[0054] Further, the surface of the concrete plate is cleaned before the waterproof material is coated on the surface of the concrete plate, so as to ensure the cleaning degree of the surface of the concrete plate and avoid the risk that the waterproof material is not closely attached to the surface of the concrete plate or even falls off after being coated due to the dust.

[0055] With reference to Figure 6 and Figure 7, in order to clean the stubborn impurities on the concrete plate, the rotating connecting shaft 561 can drive the hard bristles 562 to provide an external force to the stubborn impurities on the concrete plate, so that the stubborn impurities can fall off from the concrete plate. Specifically, the cleaning part 56 comprises a rotating connecting shaft 561 which is rotatably installed on the rotating shaft 552 through the bearing, the circumferential surface of the rotating connecting shaft 561 is uniformly provided with hard bristles 562, the fixed frame two 551 is provided with an annular rack plate 563, and the rotating connecting shaft 561 is provided with a bevel gear 564 which is engaged with the annular rack plate 563.

[0056] It should be noted that the height of the hard bristles 562 is the same as that of the cleaning brush 553, and in specific work, the rotating shaft 552 drives the rotating connecting shaft 561 to rotate circumferentially during rotation, and the rotating connecting shaft 561 rotates circumferentially during rotation through the bevel gear 564 and the annular rack plate 563, and the rotating connecting shaft 561 drives the hard bristles 562 to rotate circumferentially around the rotating connecting shaft 561 during rotation, and the hard bristles 562 can provide an external force to the stubborn impurities on the concrete plate without external force during circumferential rotation, so that the stubborn impurities can be separated from the concrete plate, and the cleanliness of the surface of the concrete plate is further improved. The stubborn impurities cleaned can be blown off around the concrete plate by the cooperation of the cleaning brush 553 and the air pipe 554.

[0057] When the surface of the concrete plate is cleaned, the electric sliding block 11 is started to drive the concrete plate to move downward by a distance through the cooperation of the supporting protrusions and the annular frame 4, so that the concrete plate and the glue outlet pipe 52 and the cleaning brush 553 have a certain distance, avoiding the collision between the glue outlet pipe 52 and the concrete plate during the movement of the fixed frame one 514. The moving frame 512 is driven to continue moving by the external drive, and the fixed frame one 514 is driven to move by the fixed frame 513 during the movement of the moving frame 512, so that the rotating shaft 515 is coaxial with the concrete plate. At this time, the fixed frame 513 drives the rotating shaft 552 to move out of the concrete plate through the fixed frame two 551.

[0058] The electric sliding block 11 is started again to drive the concrete plate to move upward by a distance through the cooperation of the supporting protrusions and the annular frame 4, and the bottom of the glue outlet pipe 52 is close to the concrete plate.

[0059] Reference Figure 5The rotating shaft 515 is composed of a rotating section installed on the fixed frame 514 and an extension section arranged at the bottom of the rotating section, and the glue outlet pipe 52 is installed at the bottom of the extension section, the rotating section of the rotating shaft 515 is provided with the lifting plate 516 through a threaded connection mode, the bottom of the fixed frame 514 is symmetrically provided with the limiting rod 517 along the length direction, and the end of the limiting rod 517 away from the fixed frame 514 penetrates through the lifting plate 516, the extension section of the rotating shaft 515 is rotatably provided with the linkage disc 518 through a bearing, and the fixed rod 519 symmetrically distributed along the length direction of the fixed frame 514 is arranged between the linkage disc 518 and the lifting plate 516.

[0060] The extension section of the rotating shaft 515 is limited and slidably arranged on the rotating section of the rotating shaft 515, that is, the rotating section of the rotating shaft 515 can synchronously drive the extension section of the rotating shaft 515 to rotate during the rotation process, and the waterproof material is pumped into the glue outlet pipe 52 through the existing pump body (not shown in the figure), and it should be noted that the waterproof material related to the present application has a certain elasticity after solidification, and in the specific work, the rotating shaft 515 is driven by the external driving motor (not shown in the figure) after the bottom of the glue outlet pipe 52 is close to the concrete plate, the rotating section of the rotating shaft 515 synchronously drives the extension section of the rotating shaft 515 to rotate during the rotation process, the extension section of the rotating shaft 515 drives the glue outlet pipe 52 to rotate circumferentially during the rotation, and the glue outlet pipe 52 can apply the waterproof material to the concrete plate during the rotation process, at this time, the glue outlet pipe 52 uniformly processes the waterproof material by driving the scraper 54.

[0061] With the increase of the rotating number of the rotating shaft 515, the lifting plate 516 has a synchronous rotation trend through the threaded connection mode during the rotation process of the rotating shaft 515, and because of the limiting 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, the linkage disc 518 is synchronously moved upward through the fixed rod 519 during the upward movement of the lifting plate 516, the extension section of the rotating shaft 515 is synchronously moved upward during the upward movement of the linkage disc 518, and the glue outlet pipe 52 is synchronously moved upward during the upward movement of the extension section of the rotating shaft 515.

[0062] Further, with the increase of the rotating number of the rotating shaft 515, the glue outlet pipe 52 is synchronously moved upward by a certain distance, and further, the distance of the upward movement of the glue outlet pipe 52 can give way to the waterproof material after being applied, avoid the possibility of collision between the waterproof material layer and the glue outlet pipe 52 and the scraper 54 due to the outflow of the waterproof material, and ensure the application effect of the waterproof material on the concrete plate.

[0063] Therefore, as the waterproof material accumulates on the concrete slab, the glue outlet pipe 52 gradually rises according to the preset lead parameters, and the scraper 54 is always in critical contact with the unhardened material layer, avoiding interference or blockage of the glue outlet pipe due to material accumulation.

[0064] When the waterproof material on the concrete slab is finished, the moving frame 512 is pushed back to its original position. At this time, the waterproof material on the concrete slab is allowed to dry and solidify. If the detection task is urgent, an existing drying machine can be used to dry the waterproof material on the concrete slab to accelerate the solidification of the waterproof material on the concrete slab.

[0065] When the waterproof material on the concrete slab solidifies, the electric sliding block 11 is started to drive the concrete slab to move upwards and be attached to the bottom of the water storage cylinder 2 through the cooperation of the support protrusions and the annular frame 4.

[0066] Referring to Figure 8 and Figure 9 , the watering mechanism 3 includes a horizontal frame 31 installed inside the water storage cylinder 2. The horizontal frame 31 is rotatably installed with a rotating rod 32 through a bearing. The bottom of the rotating rod 32 is installed with a spray pipe 33. The bottom of the spray pipe 33 is uniformly provided with a plurality of spray holes 34 along the length direction.

[0067] It should be noted that the water droplets or water flow inside the water storage cylinder 2 are colored. Therefore, when observing whether the bottom of the concrete slab is waterproof, only the area with the same color as the water on the bottom of the concrete slab needs to be observed. If there is such an area, it indicates that the waterproof effect of the concrete slab is poor. Conversely, the waterproof effect is good. According to the colored area on the bottom of the concrete, the specific water leakage position on the bottom of the concrete can be determined. The spray pipe 33 is connected with the outlet of an existing water pump (not shown in the figure). When simulating the scenario of no water accumulation on the concrete slab, an external driving motor (not shown in the figure) drives the rotating rod 32 to rotate. The rotating rod 32 drives the spray pipe 33 to rotate around the rotating rod 32 during rotation. The existing water pump pumps water into the spray pipe 33 during the rotation of the spray rod. The water droplets fall on the concrete slab through the spray holes 34 and accumulate into a flow through the water leakage hole 21. Thus, the scenario of no water accumulation on the concrete slab when it rains can be simulated. Whether there is an area with the same color as the water on the bottom of the concrete slab needs to be observed. If there is such an area, it indicates that the waterproof effect of the concrete slab is poor. Conversely, the waterproof effect is good.

[0068] Referring to Figure 10 and Figure 11The sealing block 211 is arranged inside the water leakage hole 21, the annular plate 212 is slidably arranged on the circumferential surface of the water storage cylinder 2, and the elastic extension rod 213 for resetting the annular plate 212 is jointly arranged between the annular plate 212 and the support frame 1, the linkage rod 214 corresponding to the sealing block 211 is arranged at the bottom of the annular plate 212, the guide inclined surface matched with the linkage rod 214 is arranged on the sealing block 211, and the rectangular protrusion is arranged at the bottom of the sealing block 211, and the return spring rod 215 is jointly arranged between the rectangular protrusion and the water storage cylinder 2.

[0069] In specific work, when the water accumulation scene on the concrete plate is simulated, the annular plate 212 is pressed downward by an external force (such as a pneumatic cylinder), and the linkage rod 214 is moved synchronously during the movement of the annular plate 212, at this time, the elastic extension rod 213 is stretched, and the sealing block 211 is moved to the inside of the water leakage hole 21 during the movement of the linkage rod 214 and the guide inclined surface, at this time, the return spring rod 215 is compressed, the water leakage hole 21 is blocked by the sealing block 211, and when the spray pipe 33 sprays water droplets, the water droplets accumulate on the concrete plate and are stored in the water storage cylinder 2, thereby simulating the scene of water accumulation on the concrete plate when it rains, and observing whether there is a region with the same color as water on the bottom of the concrete plate, if there is, it indicates that the waterproof effect of the concrete plate is poor, otherwise the waterproof effect is good.

[0070] In addition, the water storage cylinder 2 is also provided with a scale line, so that the amount of water in the water storage cylinder 2 can be judged according to the scale line, the deeper the water in the water storage cylinder 2, the greater the pressure on the concrete plate, thereby simulating the waterproof effect of the waterproof material on the concrete plate under different pressures.

[0071] The elastic extension rod 213 is used for resetting the annular plate 212, and the return spring rod 215 is used for resetting the sealing block 211.

[0072] Referring to Figure 9 In order to simulate different rain amount environments, the spray pipe 33 can control the size of the water flow, specifically, the slide plate 331 corresponding to the spray hole 34 and adjusting the size of the spray hole 34 is slidably arranged at the bottom of the spray pipe 33, the slide plates 331 are connected with each other through the connecting protrusions, the fixed protrusion is arranged at one end of the spray pipe 33, the linkage protrusion is arranged on the slide plate 331 close to the fixed protrusion, and the reset spring rod 332 is jointly arranged between the linkage protrusion and the connecting protrusion.

[0073] Specifically, when a large water flow is needed, the rotating rod 32 is rotated at a high speed, and the centrifugal force acting on the sliding plate 331 during the rotation of the rotating rod 32 is large, so that the sliding plate 331 moves, the reset spring rod 332 is stretched by the cooperation between the connecting protrusion and the linkage protrusion, the spray hole 34 is enlarged, and the water flow sprayed by the spray pipe 33 is variable, so that the environment during use of the waterproof material is simulated, and the detection data is more representative.

[0075] Referring to Figure 12 and Figure 13 On the basis of embodiment one, the bottom of the water storage cylinder 2 is provided with an annular groove 22, the annular groove 22 is internally provided with an annular block 23 capable of automatically resetting, the annular block 23 is provided with linkage connecting rods 24 corresponding to the water leakage holes 21, and the sealing block 211 is provided with guide inclined surfaces matched with the linkage connecting rods 24.

[0076] It should be noted that the waterproof material involved in the present application has a certain elasticity when it is solidified, and the two glue outlet holes 53 at the edge of the glue outlet pipe 52 can form an annular protrusion on the concrete slab during the circumferential rotation, so that when the concrete slab contacts the bottom of the water storage cylinder 2, the annular protrusion and the annular groove can increase the sealing performance of the contact part of the concrete slab and the bottom of the water storage cylinder 2, and in addition, the annular block 23 is driven to extrude and block the contact part of the concrete slab and the bottom of the water storage cylinder 2 when the linkage connecting rod 24 is driven to move downward, further ensuring the sealing performance of the contact part of the concrete slab and the bottom of the water storage cylinder 2.

[0077] In addition, the annular block 23 and the annular groove 22 are jointly provided with a connecting spring rod for resetting the annular block 23, and in specific operation, the annular protrusion and the annular groove 22 are matched with each other, when the sealing block 211 moves towards the inside of the water leakage hole 21, the guide inclined surface on the sealing block 211 and the linkage connecting rod 24 are matched with each other to drive the annular block 23 to move downward, the annular block 23 is extruded by the annular protrusion during the downward movement and the annular protrusion is deformed, and the deformed annular protrusion can fill the entire annular groove 22, so that the annular groove and the annular block increase the sealing performance of the contact part of the concrete slab and the bottom of the water storage cylinder. This cooperative sealing reduces water leakage and ensures the accuracy of the detection data.

[0078] The implementation principle of the present application is:

[0079] (1): the rotating shaft 552 rotates and drives the cleaning brush 553 to rotate circumferentially around the rotating shaft 552, and the cleaning brush 553 can clean the dust on the surface of the concrete slab during the circumferential rotation; the gas in the air blowing pipe 554 flows synchronously to form an air flow during the rotation of the cleaning brush 553, and the air flow can blow the cleaned dust around the concrete slab during the rotation of the cleaning brush 553.

[0080] (2): the moving frame 512 moves and drives the fixed frame 513 to move, so that the rotating shaft 515 is coaxial with the concrete slab; the rotating section synchronously drives the rotating shaft 515 to rotate during the rotation of the rotating shaft 515; the rotating shaft 515 drives the glue outlet pipe 52 to rotate circumferentially during the rotation of the rotating section; the glue outlet pipe 52 can apply waterproof material to the concrete slab during the rotation of the glue outlet pipe 52, and the glue outlet pipe 52 drives the scraper 54 to uniformly apply the waterproof material at this time.

[0081] (3): when the concrete slab is not accumulated with water, an external driving motor (not shown in the figure) drives the rotating rod 32 to rotate, and the rotating rod 32 drives the spraying pipe 33 to rotate around the rotating rod 32 during the rotation of the rotating rod 32; the existing water pump pumps water into the spraying pipe 33 during the rotation of the spraying pipe; the water flows through the spraying hole 34 and falls on the concrete slab; the water droplets accumulated on the concrete slab flow through the water leakage hole 21, thereby simulating the scene that the concrete slab is not accumulated with water when it rains, and observing whether there is an area with the same color as water on the bottom of the concrete slab.

[0082] (4): when it is necessary to simulate the scene that the concrete slab is accumulated with water, an external force (air cylinder, etc.) presses the annular plate 212 downward, and the annular plate 212 drives the linkage rod 214 to move synchronously during the movement of the annular plate 212; at this time, the elastic extension rod 213 is stretched, and the linkage rod 214 moves and cooperates with the guide slope to drive the sealing block 211 to move into the water leakage hole 21 during the movement of the linkage rod 214; at this time, the return spring rod 215 is compressed, and the water leakage hole 21 is blocked by the sealing block 211; when the spraying pipe 33 sprays water droplets, the water droplets accumulate on the concrete slab and are stored in the water storage cylinder 2, thereby simulating the scene that the concrete slab is accumulated with water when it rains, and observing whether there is an area with the same color as water on the bottom of the concrete slab.
