Description

Technical Field

[0001] This invention relates to the field of building material testing technology, and in particular to a device and method for testing the waterproof performance of green building materials. Background Technology

[0002] The waterproofing performance of green building materials directly affects their service life and effectiveness, especially the issue of water permeability, which is crucial to the durability and safety of buildings. Traditional methods for testing the waterproofing performance of building materials suffer from low efficiency and insufficient accuracy, failing to meet the current demand for high-quality testing of green building materials. Developing an efficient and accurate testing device for the waterproofing performance of green building materials can not only ensure the quality of green building materials and reduce the replacement and repair of building materials due to water permeability issues, thereby reducing energy consumption and carbon emissions, but also promote the construction industry's progress towards a zero-carbon model.

[0003] A patent with publication number CN118566009A discloses a building material waterproof performance testing device, including a box body. The box body contains a testing mechanism, which includes a clamping strip. The outer surface of the clamping strip is movably connected to the interior of the box body. An air groove is formed on the outer surface of the clamping strip. A lifting cylinder is fixedly connected to the outer surface of the clamping strip. A steam chamber is fixedly connected to the outer surface of the lifting cylinder. The outer surface of the steam chamber is fixedly connected to the interior of the box body. A partition is fixedly connected to the interior of the steam chamber. A one-way valve is fixedly connected through the body of the partition. The interior of the one-way valve is connected to the interior of the steam chamber. This invention relates to the field of building material testing technology and solves the problems of existing building material waterproof performance testing devices, which suffer from high water consumption and high heating costs, leading to increased testing costs. Furthermore, the limited testing methods result in poor actual testing results and misjudgments of the actual performance of waterproof building materials.

[0004] The existing technology has the following drawbacks: The inability to simultaneously conduct environmental simulation tests on multiple sets of identical or different samples: Traditional testing methods can only test one set of samples at a time, making it difficult to obtain test data for multiple sets of identical or different samples under different or the same environment at the same time. This results in low testing efficiency. Furthermore, because the testing time is sequential and environmental conditions may change, the test results lack comparability and cannot accurately provide a basis for evaluating the waterproof performance of building materials. Therefore, it is necessary to set up a structure that can simultaneously conduct environmental simulation tests on multiple sets of identical or different samples, such as permeability testing of identical samples (e.g., waterproof membranes, waterproof boards, etc.) under different environments, or permeability testing of different samples (e.g., concrete blocks with different layers of waterproof coating) under the same environment. This would allow for the acquisition of a large amount of test data in a short time, making the results more comparable and improving testing efficiency.

[0005] Low water utilization rate in testing: Although existing testing devices have general water circulation systems, water splashing and overflow often occur, resulting in water waste. Furthermore, the lack of reasonable planning and precise control of water usage leads to unnecessary water consumption, resulting in a low overall water utilization rate and increased testing costs. Therefore, it is necessary to establish a structure to improve water utilization rate in testing, thereby reducing water consumption and testing costs. At the same time, reasonable planning and precise control of water usage will make the testing process more scientific and efficient, improving overall testing efficiency and reflecting the green and environmentally friendly concept in the testing process. Summary of the Invention

[0006] In view of the problems of existing technology, such as the inability to conduct environmental simulation testing on multiple groups of the same or different samples at the same time and the low utilization rate of testing water, a green building material waterproof performance testing device and method is proposed.

[0007] This application provides a green building material waterproof performance testing device, the purpose of which is to: simultaneously conduct environmental simulation tests on multiple groups of identical or different samples through a set comparison clamping mechanism, such as water permeability tests of identical samples (e.g., waterproof membranes, waterproof boards, etc.) under different environments, or water permeability tests of different samples (e.g., concrete blocks with different layers of waterproof coating) under the same environment, to obtain a large amount of test data in a short time, making the results more comparable and improving the testing efficiency; at the same time, through the set testing components and circulating water supply components, the water consumption and testing costs during the testing process are reduced, and through reasonable planning and precise control of water use, the testing process is made more scientific and efficient, improving the overall testing efficiency and reflecting the green and environmentally friendly concept in the testing process.

[0008] The technical solution of the present invention is as follows: a green building material waterproof performance testing device, comprising an operating table, a testing component fixedly installed on the top of the operating table, a blower fixedly installed outside the testing component, and a circulating water supply component disposed inside the testing component. The testing component includes a testing shell fixedly connected to the top of the operating table, and a comparison clamping mechanism is disposed inside the testing shell. Multiple samples are disposed inside the comparison clamping mechanism. The comparison clamping mechanism includes a multi-stage telescopic cylinder fixedly connected to the inner wall of the detection housing, and a clamping component is fixedly connected to the output end of the multi-stage telescopic cylinder. The clamping assembly includes a slider fixedly connected to the output end of a multi-stage telescopic cylinder. A clamping frame is fixedly connected to the outer wall of the slider. The outer walls of both the slider and the clamping frame are slidably connected to the inner wall of the detection housing. The inner wall of the clamping frame is provided with a first clamping port, a second clamping port, and a third clamping port. An adjustment assembly is provided between the second clamping port and the third clamping port.

[0009] Using the above scheme, through the set comparison clamping mechanism, when it is necessary to conduct comparative tests on the same sample under different environmental simulations, the same sample (such as waterproof membrane, waterproof board, etc.) is placed into the first clamping port, the second clamping port, and the third clamping port respectively; during the scouring simulation test, the circulating water supply component is operated to spray water onto the sample in the first clamping port to simulate the water scouring environment and test the waterproof performance of the sample under water scouring; during the spray simulation test, the blower is operated, and the circulating water supply component sprays water in the form of raindrops onto the sample in the second clamping port, combined with wind power, The system simulates a spray environment to test the waterproof performance of samples under spray conditions. During immersion simulation testing, a circulating water supply assembly is used to simulate immersion testing of samples in the third clamping port, testing their waterproof performance under immersion conditions. When it is necessary to compare different samples under immersion simulation testing, a multi-stage telescopic cylinder is used to push the slider and clamping frame, then different samples (such as concrete blocks with different layers of waterproof coating) are placed in. The circulating water supply assembly is then used to store water, immersing the different samples in the same environment for simulation testing and comparison, providing a basis for evaluating the waterproof performance of building materials.

[0010] Furthermore, two compression bars are symmetrically arranged inside the first clamping port, the second clamping port, and the third clamping port, and multiple compression springs are fixedly connected between the compression bars and the clamping frame.

[0011] Furthermore, the adjustment assembly includes a first rotating block fixedly connected to the second clamping port and a second rotating block fixedly connected to the third clamping port. The inner wall of the first rotating block is fixedly connected to a flipping shaft, and the outer wall of the flipping shaft is rotatably connected to the inner wall of the second rotating block.

[0012] Furthermore, the inner wall of the first rotating block is provided with a shrinkage groove, and the outer wall of the second rotating block is fixedly connected with an arc-shaped plate, wherein the inner wall of the shrinkage groove is slidably connected to the outer wall of the arc-shaped plate.

[0013] Furthermore, the inner walls of the first clamping port, the second clamping port, and the third clamping port are all slidably connected to the outer wall of the sample. Sealing strips are provided at the connection points between the first clamping port, the second clamping port, and the third clamping port and the sample. Multiple sealing strips are fixedly connected to the outer wall of the clamping frame. Two symmetrically arranged water channels are also provided between the clamping frame and the detection housing.

[0014] Using the above scheme, with the set extrusion strip, extrusion spring and adjustment component, when the sample is placed, it first contacts the beveled surface of the extrusion strip and then is slowly pushed in. The extrusion strip compresses the extrusion spring, and the reaction force of the extrusion spring makes the surface of the sample tightly adhere to the bottom of the sealing strip. When the adjustment component is running, the rotating shaft is rotated, and the rotating shaft drives the first rotating block to rotate 90°, so that multiple clamping ports are submerged in the immersion simulation chamber. At the same time, the arc plate slides in the shrinkage groove to prevent water from entering.

[0015] Furthermore, the inner wall of the detection housing is fitted with a first sealing door and a second sealing door, which, when closed, form a sealed space with the detection housing.

[0016] Furthermore, the inside of the detection housing is fixedly connected with a baffle plate and a guide plate, and has a flushing simulation chamber, an immersion simulation chamber, a drain outlet and a water storage chamber. The baffle plate is located between the flushing simulation chamber and the immersion simulation chamber, the guide plate is located between the blower and the immersion simulation chamber, and the drain outlet is located between the immersion simulation chamber and the water storage chamber.

[0017] Using the above scheme, when it is necessary to conduct comparative tests on the same sample under different environmental conditions, the second sealed door is opened, the sample is placed in, and then the second sealed door is closed, which can form a sealed space in the test shell. When the door is closed, the door and the clamping frame are precisely combined, so that the sample is stably placed in the clamping opening, and the gap between the sample and the clamping frame is wrapped by the sealing strip to prevent water penetration during the test.

[0018] Furthermore, the circulating water supply assembly includes a water pump fixedly connected to the outer wall of the detection housing, and a straight suction pipe fixedly connected to the bottom of the water pump, the straight suction pipe being disposed inside the water storage chamber.

[0019] Furthermore, the circulating water supply assembly also includes multiple pressure-regulating nozzles and multiple raindrop nozzles fixedly connected to the inner wall of the detection housing. The multiple pressure-regulating nozzles are arranged in the flushing simulation chamber, and the multiple raindrop nozzles are arranged in the immersion simulation chamber. The multiple pressure-regulating nozzles and the multiple raindrop nozzles are connected to the water pump by a water supply pipe.

[0020] Using the above scheme, during the rinsing simulation test using the set circulating water supply component, the water pump draws water from the storage chamber through the suction pipe, and the water is transported through the water supply pipe to the pressure regulating nozzle in the rinsing simulation chamber. The pressure regulating nozzle sprays water onto the sample in the first clamping port at a certain pressure. During the spray simulation test, the circulating water supply component transports water to the raindrop nozzle, which sprays water onto the sample in the second clamping port in the form of raindrops. When it is necessary to compare different samples by immersion simulation test, the immersion simulation chamber can be filled with water through the pressure regulating nozzle and the raindrop nozzle. After the test is completed, the test water flows into the storage chamber through the drain outlet, and the circulating water supply component transports the water in the storage chamber back to the pressure regulating nozzle and the raindrop nozzle, realizing water recycling, reducing test costs, and reflecting the concept of green environmental protection.

[0021] Another aspect of this application provides a testing method for a green building material waterproof performance testing device, which includes the following steps: Step 1: When it is necessary to conduct comparative tests on the same sample under different environmental simulations, open the second sealed chamber door and place the same sample inside. Step 2: Close the second sealed chamber door, run the circulating water supply assembly, and perform a simulated flushing test on the sample in the first clamping port; Step 3: Run the blower to spray the sample in the second clamping port for simulated testing; Step 4: The water from Steps 2 and 3 flows into the immersion simulation chamber to conduct a water immersion simulation test on the sample in the third clamping port; Step 5: Simultaneous flushing, spraying, and immersion simulation tests are conducted on the same sample under different environmental conditions and the results are compared. Step Six: When it is necessary to conduct immersion simulation tests and comparisons on different samples, operate the multi-stage telescopic cylinder and adjustment components for adjustment; Step 7: Open the first sealed chamber door and place different samples inside; Step 8: Run the circulating water supply component to fill the immersion simulation chamber with water, and conduct the same environmental simulation test on different samples and compare them.

[0022] Using the above scheme, when it is necessary to conduct comparative tests on the same sample under different environmental simulations, the second sealed door is opened, and the same sample (such as waterproof membrane, waterproof board, etc.) is placed into the first clamping port, the second clamping port, and the third clamping port respectively. Then, the second sealed door is closed to form a sealed space in the test shell. During the scouring simulation test, the circulating water supply component is operated to spray water at a certain pressure onto the sample in the first clamping port to simulate the water scouring environment and test the waterproof performance of the sample under water scouring. During the spray simulation test, the blower is operated, and the air is blown into the immersion simulation chamber through the air guide plate. At the same time, the circulating water supply component sprays water in the second clamping port in the form of raindrops. Combined with the wind force, the spray environment is simulated to test the waterproof performance of the sample under spray. During the wading simulation test, the water after the scouring simulation test is... Water flows into the immersion simulation chamber from the water tank, and water from the spray simulation test naturally falls into the immersion simulation chamber. Partially open the drain outlets ensure a constant water content within the immersion simulation chamber, allowing for a water immersion simulation test on the sample in the third clamping port to assess its waterproof performance under water immersion conditions. These three simulation tests are performed simultaneously, enabling the same sample to undergo different environmental simulation tests and comparisons, acquiring a large amount of test data in a short time and improving testing efficiency. When comparing immersion simulation tests on different samples, a multi-stage telescopic cylinder and adjustment components are used for adjustment. Then, different samples (such as concrete blocks with different layers of waterproof coating) are placed in, and the immersion simulation chamber is filled with water through a circulating water supply component, immersing the different samples in the same environment for simulation testing and comparison, providing a basis for evaluating the waterproof performance of building materials.

[0023] The beneficial effects of this invention are: 1. Through the set comparison clamping mechanism, when it is necessary to conduct comparative tests on the same sample under different environmental conditions, the same sample (such as waterproof membrane, waterproof board, etc.) is placed into the first clamping port, the second clamping port, and the third clamping port respectively; rinsing simulation test, spraying simulation test, and immersion simulation test are carried out in sequence; when it is necessary to conduct comparative tests on different samples under immersion simulation test, the multi-stage telescopic cylinder is operated to push the slider and clamping frame, and then different samples (such as concrete blocks with different layers of waterproof coating) are placed in. The circulating water supply component is operated to store water, so that the different samples are immersed in water, and the same environmental simulation test is carried out and compared. In this way, a large amount of test data can be obtained in a short time, making the results more comparable and achieving the effect of improving the test efficiency.

[0024] 2. During the rinsing simulation test using the set-up circulating water supply component, the water pump draws water from the storage chamber through the suction pipe. The water is then transported through the supply pipe to the pressure-regulating nozzle in the rinsing simulation chamber, where it sprays water at a certain pressure onto the sample in the first clamping port. During the spray simulation test, the circulating water supply component delivers water to the raindrop nozzle, which sprays water in a raindrop pattern onto the sample in the second clamping port. When it is necessary to compare different samples using immersion simulation tests, the immersion simulation chamber can be filled with water using the pressure-regulating nozzle and the raindrop nozzle. After the test is completed, the test water flows into the storage chamber through the drain outlet. The circulating water supply component then delivers the water from the storage chamber back to the pressure-regulating nozzle and the raindrop nozzle, achieving water recycling, reducing testing costs, and embodying the concept of green environmental protection.

[0025] 3. Through the set detection components and water flow channel, when it is necessary to conduct comparative tests on the same sample under different environmental simulations, the second sealed chamber door is opened, the sample is placed in, and then the second sealed chamber door is closed, which can form a sealed space in the detection shell. When the chamber door is closed, the chamber door is precisely combined with the clamping frame, so that the sample is stably placed in the clamping opening, and the gap between the sample and the clamping frame is wrapped by the sealing strip to prevent the detection water from seeping in. When conducting water immersion simulation tests, the water after the rinsing simulation test flows into the immersion simulation chamber through the water flow channel, and the water after the spray simulation test falls naturally into the immersion simulation chamber. Some drain outlets are opened to keep a certain water content in the immersion simulation chamber at all times, thereby improving the utilization rate of detection water. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example 1, referring to Figures 1-11 The first embodiment of the present invention provides a green building material waterproof performance testing device, including an operating table 1, a testing component 2 fixedly installed on the top of the operating table 1, a blower 3 fixedly installed outside the testing component 2, and a circulating water supply component 4 disposed inside the testing component 2. The testing component 2 includes a testing shell 21 fixedly connected to the top of the operating table 1. A comparison clamping mechanism 5 is disposed inside the testing shell 21, and multiple samples 6 are disposed inside the comparison clamping mechanism 5.

[0030] Reference Figures 6-10The clamping mechanism 5 includes a multi-stage telescopic cylinder 54 fixedly connected to the inner wall of the detection housing 21. The output end of the multi-stage telescopic cylinder 54 is fixedly connected to a clamping assembly 51. The clamping assembly 51 includes a slider 515 fixedly connected to the output end of the multi-stage telescopic cylinder 54. The outer wall of the slider 515 is fixedly connected to a clamping frame 511. The outer walls of both the slider 515 and the clamping frame 511 are slidably connected to the inner wall of the detection housing 21. The inner wall of the clamping frame 511 is provided with a first clamping port 512, a second clamping port 513 and a third clamping port 514. An adjustment assembly 55 is provided between the second clamping port 513 and the third clamping port 514.

[0031] By using the comparison clamping mechanism 5, when it is necessary to conduct comparative tests on the same sample 6 under different environmental simulations, the same sample 6 (such as waterproof membrane, waterproof board, etc.) is placed into the first clamping port 512, the second clamping port 513, and the third clamping port 514 respectively. During the scouring simulation test, the circulating water supply component 4 sprays water onto the sample 6 in the first clamping port 512 to simulate a water scouring environment and test the waterproof performance of the sample 6 under water scouring. During the spray simulation test, the blower 3 is operated, and the circulating water supply component 4 sprays water in the form of raindrops onto the sample 6 in the second clamping port 513, combined with wind power, to simulate... In a simulated spray environment, the waterproof performance of sample 6 under spray conditions is tested. During the water immersion simulation test, the circulating water supply component 4 is operated to conduct a water immersion simulation test on sample 6 in the third clamping port 514 to test the waterproof performance of sample 6 under water immersion conditions. When it is necessary to conduct immersion simulation tests on different samples 6 for comparison, the multi-stage telescopic cylinder 54 is operated to push the slider 515 and the clamping frame 511, and then different samples 6 (such as concrete blocks with different layers of waterproof coating) are placed in. The circulating water supply component 4 is operated to store water, so that different samples 6 are immersed in water, and the same environmental simulation test is conducted and compared to provide a basis for the evaluation of the waterproof performance of building materials.

[0032] Reference Figures 6-10Each of the first clamping port 512, the second clamping port 513, and the third clamping port 514 has two symmetrically arranged extrusion strips 516 inside. Multiple extrusion strips 516 are fixedly connected to the clamping frame 511 by multiple extrusion springs 517. The adjusting assembly 55 includes a first rotating block 551 fixedly connected to the second clamping port 513 and a second rotating block 552 fixedly connected to the third clamping port 514. A flipping shaft 555 is fixedly connected to the inner wall of the first rotating block 551, and the outer wall of the flipping shaft 555 is rotatably connected to the inner wall of the second rotating block 552. The inner wall of the first rotating block 551 has an opening... The sample 6 has a shrinkage groove 553, and an arc plate 554 is fixedly connected to the outer wall of the second rotating block 552. The inner wall of the shrinkage groove 553 is slidably connected to the outer wall of the arc plate 554. The inner walls of the first clamping port 512, the second clamping port 513 and the third clamping port 514 are all slidably connected to the outer wall of the sample 6. Sealing strips 52 are provided at the connection between the first clamping port 512, the second clamping port 513 and the third clamping port 514 and the sample 6. Multiple sealing strips 52 are fixedly connected to the outer wall of the clamping frame 511. Two symmetrically arranged water channels 53 are also provided between the clamping frame 511 and the detection housing 21.

[0033] Specifically, the extrusion strip 516 can achieve a uniform and stable extrusion effect on the sample 6 placed inside; when the sample 6 is placed into the corresponding clamping opening, the extrusion strip 516 will move due to the extrusion of the sample 6, thereby compressing the extrusion spring 517. The extrusion spring 517 will generate a reaction force during the compression process, so that the extrusion strip 516 presses tightly against the sample 6, thereby ensuring that the sample 6 can be stably placed in the clamping opening, avoiding shaking or displacement during the test, and ensuring the accuracy of the test results; the arc plate 554 can prevent moisture from corroding or damaging components such as the flip shaft 555, thereby extending the service life of the adjustment component 55 and ensuring its long-term stable operation; the sealing strip 52 can prevent test water from seeping into other parts during the test, such as water flow, spraying, wading, etc., thereby ensuring the independence of the test environment and the accuracy of the test results.

[0034] When the sample 6 is placed in, it first contacts the beveled surface of the extrusion bar 516 via the extrusion bar 516, and then is slowly pushed in. The extrusion bar 516 compresses the extrusion spring 517, and the reaction force of the extrusion spring 517 makes the surface of the sample 6 tightly adhere to the bottom of the sealing strip 52. When the adjustment component 55 is running, the rotating shaft 555 is rotated, which drives the first rotating block 551 to rotate 90°, so that multiple clamping ports are submerged in the immersion simulation chamber 27. At the same time, the arc plate 554 slides in the shrinkage groove 553 to prevent water from entering.

[0035] Reference Figures 2-5The inner wall of the detection housing 21 is fitted with a first sealed door 22 and a second sealed door 23. When the first sealed door 22 and the second sealed door 23 are closed, they form a sealed space with the detection housing 21. The inside of the detection housing 21 is fixedly connected with a baffle plate 25 and a guide plate 26, and has a flushing simulation chamber 24, an immersion simulation chamber 27, a drain outlet 28 and a water storage chamber 29. The baffle plate 25 is located between the flushing simulation chamber 24 and the immersion simulation chamber 27, the guide plate 26 is located between the blower 3 and the immersion simulation chamber 27, and the drain outlet 28 is located between the immersion simulation chamber 27 and the water storage chamber 29.

[0036] Specifically, when the blower 3 is turned on, the air guide plate 26 can evenly guide the air force to the immersion simulation chamber 27, so that in the immersion simulation test, the combined effect of wind and water flow can more realistically simulate complex situations such as wind and rain in the natural environment. By adjusting the angle and position of the air guide plate 26, the magnitude and direction of the wind force can be flexibly changed according to different test requirements. When the water level is too high, the excess water can flow into the water storage chamber 29 through the drain outlet 28 to realize the recycling of water resources. The operator can adjust the opening degree and number of drain outlets 28 to precisely control the water content in the immersion simulation chamber 27, creating different water immersion environments for the sample 6 to meet diverse test requirements. The water storage chamber 29 provides a water source for the circulating water supply component 4, ensuring a continuous supply of water resources throughout the entire test process.

[0037] When different environmental simulation tests are required to compare the same sample 6, the second sealed door 23 is opened by the detection component 2, the sample 6 is placed in, and then the second sealed door 23 is closed, so that the detection shell 21 can form a sealed space. When the door is closed, the door is precisely engaged with the clamping frame 511, so that the sample 6 is stably placed in the clamping opening, and the gap between the sample 6 and the clamping frame 511 is wrapped by the sealing strip 52 to prevent the detection water from seeping in.

[0038] Reference Figures 2-4 The circulating water supply assembly 4 includes a water pump 41 fixedly connected to the outer wall of the detection housing 21. A straight suction pipe 43 is fixedly connected to the bottom of the water pump 41 and is located inside the water storage chamber 29. The circulating water supply assembly 4 also includes multiple pressure regulating nozzles 44 and multiple raindrop nozzles 45 fixedly connected to the inner wall of the detection housing 21. The multiple pressure regulating nozzles 44 are located inside the flushing simulation chamber 24, and the multiple raindrop nozzles 45 are located inside the immersion simulation chamber 27. A water supply pipe 42 connects the multiple pressure regulating nozzles 44 and the multiple raindrop nozzles 45 to the water pump 41.

[0039] Specifically, when the water pump 41 is started, the suction pipe 43 can continuously draw water from the water storage chamber 29 to provide water for subsequent simulation tests; the pressure regulating nozzle 44 has a pressure regulating function, which can change the water jet pressure and flow rate; the raindrop nozzle 45 can make water fall in a dispersed, raindrop-like form.

[0040] When performing a flushing simulation test using the circulating water supply component 4, the water pump 41 draws water from the storage chamber 29 through the suction pipe 43. The water is then transported through the water supply pipe 42 to the pressure regulating nozzle 44 in the flushing simulation chamber 24. The pressure regulating nozzle 44 sprays the water at a certain pressure onto the sample 6 in the first clamping port 512. When performing a spraying simulation test, the circulating water supply component 4 delivers water to the raindrop nozzle 45, which sprays the water in the form of raindrops onto the sample 6 in the second clamping port 513. When it is necessary to perform immersion simulation tests on different samples 6 for comparison, the immersion simulation chamber 27 can be filled with water through the pressure regulating nozzle 44 and the raindrop nozzle 45. After the test is completed, the test water flows into the storage chamber 29 through the drain port 28. The circulating water supply component 4 then delivers the water in the storage chamber 29 back to the pressure regulating nozzle 44 and the raindrop nozzle 45, realizing water recycling, reducing testing costs, and embodying the concept of green environmental protection.

[0041] During use, when it is necessary to conduct comparative tests on the same sample 6 under different environmental simulations, open the second sealed door 23 and place the same sample 6 (such as waterproof membrane, waterproof board, etc.) into the first clamping port 512, the second clamping port 513, and the third clamping port 514 respectively. Then close the second sealed door 23 to form a sealed space in the test shell 21. When conducting the flushing simulation test, run the circulating water supply component 4 to spray water at a certain pressure onto the sample 6 in the first clamping port 512 to simulate the water flow flushing environment and test the waterproof performance of the sample 6 under water flow flushing. When conducting the spraying simulation test, run the blower 3, and blow air through the air guide plate 26 to the immersion simulation chamber 27. At the same time, the circulating water supply component 4 sprays water in the second clamping port 513 in the form of raindrops onto the sample 6. Combined with the wind force, simulate the spraying environment and test the waterproof performance of the sample 6 under spraying. When conducting the wading simulation test, after the flushing simulation test... Water flows into the immersion simulation chamber 27 through the water trough 53. Water from the spray simulation test naturally falls into the immersion simulation chamber 27, and some drain outlets 28 are opened to maintain a certain water content in the immersion simulation chamber 27. This allows for a water immersion simulation test on the sample 6 in the third clamping port 514 to test the waterproof performance of the sample 6 under water immersion conditions. These three simulation tests are performed simultaneously, allowing for different environmental simulation tests on the same sample 6 and comparison, obtaining a large amount of test data in a short time and improving testing efficiency. When it is necessary to compare different samples 6 under immersion simulation tests, the multi-stage telescopic cylinder 54 and the adjustment component 55 are operated for adjustment. Then, different samples 6 (such as concrete blocks with different layers of waterproof coating) are placed in, and the immersion simulation chamber 27 is filled with water through the circulating water supply component 4, so that different samples 6 are immersed in water and subjected to the same environmental simulation test for comparison, providing a basis for evaluating the waterproof performance of building materials.

[0042] Example 2, refer to Figures 1-11 The second embodiment of the present invention provides a testing method for a green building material waterproof performance testing device, which includes the following steps: Step 1: When it is necessary to conduct comparative tests on the same sample 6 under different environmental simulations, open the second sealed door 23 and place the same sample 6 inside; Step 2: Close the second sealed chamber door 23, run the circulating water supply assembly 4, and perform a flushing simulation test on the sample 6 in the first clamping port 512; Step 3: Run blower 3 to perform spray simulation test on sample 6 in the second clamping port 513; Step 4: The water from Step 2 and Step 3 flows into the immersion simulation chamber 27, and the sample 6 in the third clamping port 514 is subjected to immersion simulation test. Step 5: Simultaneous flushing, spraying, and immersion simulation tests are conducted on the same sample 6 under different environmental simulation tests and the results are compared. Step Six: When it is necessary to conduct immersion simulation testing and comparison on different samples 6, the multi-stage telescopic cylinder 54 and the adjustment component 55 are operated for adjustment; Step 7: Open the first sealed chamber door 22 and put in different samples 6; Step 8: Run the circulating water supply component 4 to fill the immersion simulation chamber 27 with water, and conduct the same environmental simulation test on different samples 6 and compare them.

[0043] Working principle of the invention: When it is necessary to conduct comparative tests on the same sample 6 under different environmental simulations, open the second sealed door 23, and place the same sample 6 (such as waterproof membrane, waterproof board, etc.) into the first clamping port 512, the second clamping port 513 and the third clamping port 514 respectively. Then close the second sealed door 23 to make the test shell 21 form a sealed space.

[0044] When sample 6 is placed in, it first contacts the beveled surface of the extrusion strip 516, and then slowly pushes sample 6 in along the extrusion strip 516. Sample 6 compresses the extrusion spring 517 through the extrusion strip 516. The reaction force of the extrusion spring 517 makes the surface of sample 6 tightly adhere to the bottom of the sealing strip 52. When the hatch is closed, the hatch is precisely engaged with the clamping frame 511, so that sample 6 is stably placed in the clamping opening, and the sealing strip 52 covers the gap between sample 6 and clamping frame 511 to prevent water from seeping in during testing.

[0045] During the scouring simulation test, the circulating water supply component 4 is operated. The water pump 41 draws water from the water storage chamber 29 through the water suction straight pipe 43. The water is transported through the water supply pipe 42 to the pressure regulating nozzle 44 in the scouring simulation chamber 24. The pressure regulating nozzle 44 sprays water at a certain pressure onto the sample 6 in the first clamping port 512 to simulate the water flow scouring environment and test the waterproof performance of the sample 6 under water flow scouring.

[0046] During the spray simulation test, the blower 3 is run, and the air is blown through the air guide plate 26 to the immersion simulation chamber 27. At the same time, the circulating water supply component 4 delivers water to the raindrop nozzle 45. The raindrop nozzle 45 sprays water in the form of raindrops onto the sample 6 in the second clamping port 513. Combined with the wind force, the spray environment is simulated to test the waterproof performance of the sample 6 under spray.

[0047] During the water immersion simulation test, the water after the rinsing simulation test flows into the immersion simulation chamber 27 through the water channel 53, and the water after the spray simulation test falls naturally into the immersion simulation chamber 27. The drain outlets 28 are partially opened to keep the immersion simulation chamber 27 at a certain water content. Thus, the water immersion simulation test is carried out on the sample 6 in the third clamping port 514 to test the waterproof performance of the sample 6 under water immersion conditions.

[0048] These three simulation tests can be performed simultaneously, allowing for simulation testing and comparison of the same sample 6 under different environments. This enables the acquisition of a large amount of test data in a short period of time, thereby improving testing efficiency.

[0049] When different samples 6 need to be immersed in simulated tests for comparison, the multi-stage telescopic cylinder 54 is operated to push the slider 515 along with the clamping frame 511 to the first sealed door 22, the first sealed door 22 is opened, the flipping shaft 555 is rotated, the flipping shaft 555 drives the first rotating block 551 to rotate 90°, so that multiple clamping ports are submerged in the immersion simulation chamber 27, and at the same time the arc plate 554 slides in the shrinkage groove 553 to prevent water from entering.

[0050] Next, different samples 6 (such as concrete blocks with different layers of waterproof coating) are placed in the immersion simulation chamber 27 and water is filled through the pressure regulating nozzle 44 and the raindrop nozzle 45, so that different samples 6 are immersed in water, and the same environmental simulation test is carried out and compared to provide a basis for evaluating the waterproof performance of building materials.

[0051] After the test is completed, the test water flows into the water storage chamber 29 through the drain outlet 28. The circulating water supply component 4 then transports the water in the water storage chamber 29 back to the pressure regulating nozzle 44 and the raindrop nozzle 45, realizing the recycling of water, reducing the test cost, and reflecting the concept of green environmental protection.
