Description

Technical Field

[0001] The present invention relates to the field of detection technology, in particular to a device for testing the anti-penetration performance of a waterproof coiled material. Background Art

[0002] Building waterproofing materials are the material foundation of waterproofing projects and serve as the primary barrier to protect buildings and structures from rainwater intrusion, groundwater, and other moisture infiltration. The quality of waterproofing materials significantly impacts waterproofing projects, making it crucial to test the anti-penetration properties of building waterproofing materials.

[0003] After searching, a Chinese patent with patent announcement number CN119104478B is found, which is a waterproof membrane performance testing device, including: a testing cylinder for placing the waterproof membrane to be tested; a water adding and pressurizing mechanism for adding water and pressurizing the waterproof membrane in the testing cylinder for testing; the water adding and pressurizing mechanism includes a support plate, a water storage tank, a water adding airbag, a pressurizing airbag and a pressurizing plate; a dual-purpose air pump for pumping or inflating the water adding airbag and the pressurizing airbag; an air flow channel switching mechanism for switching the connection state between the dual-purpose air pump and the water adding airbag and the pressurizing airbag, the dual-purpose air pump and the air flow channel switching mechanism are connected to the main air pipe, and the air flow channel switching mechanism is connected to the water adding airbag and the pressurizing airbag through bronchus one and bronchus two respectively.

[0004] While the aforementioned patent is capable of testing the waterproofing membrane's penetration resistance, its design lacks a function for automatically flattening the membrane. Because the membrane must be manually positioned in the test area, wrinkles in the membrane that are not properly handled before penetration testing can affect the accuracy of the test results. Even after securing, wrinkles can lead to uneven local stress distribution and mask existing defects (such as bubbles and weak seams). These problems can be exacerbated by tension and create new leaks, thus affecting the reliability of the test results. Summary of the Invention

DETAILED DESCRIPTION

[0029] See also Figures 1-4, a waterproof membrane anti-permeability test detection device, including a base 1, two left and right guide rails 2 are installed on the top of the base 1, a lifting plate 3 is slidingly provided between the two guide rails 2, and an upper detection cylinder 4 is connected to the lifting plate 3, and the top of the base 1 is connected to a lower detection cylinder 6 located just below the upper detection cylinder 4, the lower detection cylinder 6 and the front lower part of the upper detection cylinder 4 are connected to a drain valve pipe 43, the top of the upper detection cylinder 4 is connected to an air supply pipe 41 and a water supply pipe 42, the air supply pipe 41 is located on the right side of the water supply pipe 42, and a driving member 5 for driving the lifting plate 3 to rise and fall is provided on the left guide rail 2. In a specific implementation, the driving member 5 can be a driving device such as a screw motor, an electric push rod, or a cylinder that can achieve precise reciprocating movement. A flattening mechanism for flattening the waterproof membrane is provided between the upper detection cylinder 4 and the lower detection cylinder 6. The flattening mechanism includes a mounting seat 70 and a telescopic plate 71. The outer wall of the upper detection cylinder 4 is uniformly distributed along the circumference. The lock body 71 of the present invention is fixed with two locks 71 and 72, and two locks 71 are fixed on the top of the lock body 71. The lock body 71 is fixed with two locks 71 and 72. The lock body 71 is fixed with a spring 72 and a spring 72. The lock body 71 is fixed with a spring 72 and a spring 72. The lock body 71 is fixed with a spring 72 and a spring 72. The lock body 71 is fixed with a spring 72 and a spring 72. The lock body 71 is fixed with a spring 72

[0030] First, place the cut sheet of waterproofing membrane on top of the lower detection tube 6. Then control the drive element 5 to drive the lifting plate 3 to drive the upper detection tube 4 downward, thereby driving the upper clamping block 74 downward to cooperate with the lower clamping block 77 to clamp the waterproofing membrane. After the upper clamping block 74 moves down to cooperate with the lower clamping block 77 to clamp the waterproofing membrane, the upper clamping block 74 cannot move further downward. The support of the spring 2 73 prevents the telescopic plate 71 from immediately retracting. As a result, the upper detection tube 4 drives the telescopic plate 71 to continue to move downward through the mounting seat 70, causing the telescopic plate 71 to swing outward, stretching the spring 1 72, and thus moving the upper clamping block 74 outward. Because the clamping parts of the upper clamping block 74 and the lower clamping block 77 are both designed as tooth-like structures, the downward movement of the upper clamping block 74 can insert into the tooth-like structure of the lower clamping block 77. Therefore, the outward movement of the upper clamping block 74 pushes the lower clamping block 77 outward synchronously, stretching the spring 3 78. The synchronous outward movement of the upper clamping block 74 and the lower clamping block 77 can pull the waterproof membrane outward to flatten the waterproof membrane, ensuring that the test area of ​​the waterproof membrane is flat and wrinkle-free, avoiding detection errors caused by wrinkles in the waterproof membrane, thereby improving the accuracy and reliability of the waterproof membrane anti-penetration performance test, and thus being able to truly and objectively reflect the actual anti-penetration performance of the waterproof membrane. The elastic force of the torsion spring 75 can keep the upper clamping block 74 in a horizontal state and cooperate with the lower clamping block 77 to firmly clamp the waterproof membrane. When the lower clamping block 77 moves outward to the limit, it locks the upper clamping block 74, causing the upper clamping block 74 to stop moving outward, and the telescopic plate 71 stops swinging outward, so that the upper detection tube 4 drives the mounting seat 70 to continue to move downward, causing the telescopic plate 71 to contract and compress the spring 2 73, so that it can adapt to waterproof membranes of different thicknesses.

[0031] After the upper detection tube 4 is moved down and covered on the lower detection tube 6, a sealed detection space is formed to prevent gas and water from leaking from the detection space during the subsequent anti-penetration performance test of the waterproof membrane, which may affect the accuracy of the test results. The required test pressure conditions can be maintained to ensure the authenticity and reliability of the experimental data. Then, the air supply pipe 41 is connected to the air supply equipment, and the water supply pipe 42 is connected to the water supply equipment. The upper detection tube 4 is directly supplied with water and air through the air supply equipment and the water supply pipe 42 to realize water injection and pressurization of the waterproof membrane, thereby realizing the anti-penetration performance test of the waterproof membrane. The upper detection tube 4 and the lower detection tube 6 are both made of transparent materials to facilitate checking whether the waterproof membrane is leaking water. If the waterproof membrane is leaking water, it means that the anti-penetration performance is unqualified. If the waterproof membrane is not leaking water, it means that the anti-penetration performance is qualified. Connect the drain valve tube 43 to the hose. After the inspection is completed, first open the valve on the drain valve tube 43 to drain the water to a suitable location. Then control the driving member 5 to drive the lifting plate 3 to drive the upper detection tube 4 to move up and reset, thereby driving the mounting seat 70, the telescopic plate 71 and the upper clamping block 74 to move up and reset, loosen the waterproof membrane, and under the reset action of the spring 1 72, pull the telescopic plate 71 to swing inward and reset, thereby driving the upper clamping block 74 to move inward and reset. Under the reset action of the spring 3 78, pull the lower clamping block 77 to move inward and reset.

[0032] In actual application scenarios, waterproof membranes often deform due to factors such as stretching during installation and environmental stress. However, existing testing equipment is often unable to simulate these tensile deformations under real-world conditions, resulting in inconsistent test results and actual performance, which in turn affects the accuracy and reliability of the test. To address this issue, more accurately simulate the actual state of waterproof membranes in use and improve the actual reference value of test results, please refer to Figure 5-Figure 7, a pulling mechanism is provided between the upper detection tube 4 and the lower detection tube 6 for pulling the waterproof membrane to stretch, the pulling mechanism includes a guide rail three 81 and a clamping block 82, the lower part of the inner wall of the upper detection tube 4 and the upper part of the inner wall of the lower detection tube 6 are connected with four guide rails three 81 evenly spaced along the circumferential direction, a clamping block 82 is slidably provided in the guide rail three 81, the four clamping blocks 82 in the lower detection tube 6 are respectively located directly below the four clamping blocks 82 in the upper detection tube 4, the clamping part of the clamping block 82 is designed as a tooth-shaped structure, compared with a smooth surface, the tooth structure can better embed into the surface of the waterproof membrane, provide stronger gripping force, thereby more firmly clamping the waterproof membrane, a tension sensor 83 is installed on the clamping block 82 in the upper detection tube 4, and two magnets 84 are embedded and symmetrically installed on the clamping part of the clamping block 82, two springs four 85 are connected between the clamping block 82 in the lower detection tube 6 and the guide rail three 81, and a spring 85 is provided in the upper detection tube 4 for driving it The inner clamping block 82 is driven by a drive assembly that moves back and forth horizontally. The drive assembly includes a mounting plate 86 and a ring 87. Four mounting plates 86 are connected to the lower portion of the inner wall of the upper detection cylinder 4 at even intervals along the circumferential direction. Each mounting plate 86 is located between two adjacent guide rails 3 81 in the upper detection cylinder 4. Two inner and outer rings 87 are rotatably connected between the four mounting plates 86. The rings 87 are located on the upper side of the guide rail 3 81 and the clamping block 82 in the upper detection cylinder 4. The inner and outer rings 87 are connected to the inner and outer rings 87. Four slotted inclined plates 88 are connected at even intervals along the circumferential direction. The four clamping blocks 82 in the upper detection cylinder 4 are connected with L-shaped pull rods 89. The four L-shaped pull rods 89 are respectively located in the grooves of the four slotted inclined plates 88. A stepper motor 810 is installed on the mounting plate 86 on the right front side. A gear 811 is connected to the output shaft of the stepper motor 810. An arc-shaped rack 812 is connected to the inner wall of the outer ring 87, and the arc-shaped rack 812 is engaged with the gear 811.

[0033] The downward movement of upper detection tube 4 drives guide rail 3 81 and clamping block 82 therein downward. Clamping block 82 in upper detection tube 4 then moves downward, cooperating with clamping block 82 in lower detection tube 6 to clamp the waterproof membrane. The membrane has now been pulled outward and flattened by upper clamping block 74 and lower clamping block 77. Stepper motor 810 is then controlled to rotate gear 811, driving arcuate rack 812 and outer ring 87, which in turn rotates slotted ramp 88. The rotation of slotted ramp 88 pushes pull rod 89, moving clamping block 82 in upper detection tube 4 outward. Because the clamping block 82 is provided with a magnet 84, when the clamping block 82 in the upper detection tube 4 moves downward, the magnet 84 locks the clamping block 82 in the upper detection tube 4 and the clamping block 82 in the lower detection tube 6 together. The clamping block 82 in the upper detection tube 4 then moves outward, driving the clamping block 82 in the lower detection tube 6 to move outward synchronously, thereby stretching the flattened waterproof membrane outward. This simulates the tensile deformation that the membrane may experience in actual use, effectively simulating the anti-penetration performance of the waterproof membrane under real-world conditions. This not only further improves the accuracy and reliability of the waterproof membrane's anti-penetration performance testing, but also more realistically and objectively reflects the actual anti-penetration performance of the waterproof membrane during long-term use. The tension sensor 83 can detect the tension applied to the waterproof membrane in real time. By electrically connecting the tension sensor 83 to a display screen, the tension value can be transmitted to the display screen for display, allowing inspectors to understand the tension applied to the waterproof membrane. Similarly, when the clamping block 82 needs to be moved inward to reset, the stepping motor 810 is controlled to drive the gear 811 to rotate in the reverse direction.

[0034] Existing testing equipment mainly focuses on the initial performance evaluation of new waterproof membranes, but lacks effective evaluation of the changes in their permeability after a period of actual use, that is, after they have experienced wear and tear. It fails to simulate the permeability of waterproof membranes after actual use and wear and tear, making it difficult to truly reflect the actual performance of waterproof membranes after actual use and wear and tear. To solve this problem, more accurately simulate the state of waterproof membranes after actual use and wear and tear, and improve the actual reference value of test results, please refer to Figure 8-Figure 9, a friction mechanism for rubbing the surface of the waterproof membrane is provided between the upper detection tube 4 and the lower detection tube 6, the friction mechanism includes a guide rod 91, a lifting plate 2 92, a support ring 93 and a cover body 94. A support ring 93 is provided in the lower detection tube 6, and a cover body 94 matching the support ring 93 is provided in the upper detection tube 4. The diameter of the cover body 94 is smaller than the diameter of the inner ring 87. The outer walls of the cover body 94 and the support ring 93 are connected with two lifting plates 2 92 at intervals along the circumferential direction. The right side of the inner wall of the upper detection tube 4 and the lower detection tube 6 is connected with a guide rod 91, the right lifting plate 2 92 on the cover body 94 is slidably connected to the guide rod 91 in the upper detection tube 4, and the right lifting plate 2 92 on the support ring 93 is slidably connected to the guide rod 91 in the lower detection tube 6. The left side of the inner wall of the upper detection tube 4 and the lower detection tube 6 is installed with a driving member 2 95, and the driving member 2 95 in the upper detection tube 4 is used The left lifting plate 92 on the cover body 94 is driven to rise and fall, and the driving member 95 in the lower detection tube 6 is used to drive the left lifting plate 92 on the support ring 93 to rise and fall. In a specific implementation, the driving member 95 can be an electric slide rail, a linear motor, a screw motor, an electric push rod, a cylinder, or other driving devices that can achieve precise reciprocating movement. A servo motor 96 is installed in the top middle of the cover body 94. The output shaft of the servo motor 96 is connected to an outer diamond rod 97. The outer diamond rod 97 extends into the cover body 94 and is slidably sleeved with an inner diamond rod 98. A spring 99 is connected between the inner diamond rod 98 and the outer diamond rod 97. The bottom end of the inner diamond rod 98 is rotatably connected to a friction rod 910 through a bearing. The friction rod 910 is spaced apart with protrusions for increasing friction. An annular heating tube 10 is installed on the inner top of the cover body 94 for heating and drying the waterproof membrane.

[0035] After completing a test and draining the water from the upper and lower test tubes 4 and 6, the two drive elements 2 (95) are controlled to move the upper and lower lift plates 2 (92) on the left side toward each other, thereby moving the support ring 93 and the cover 94 toward each other. The support ring 93 moves upward to support the waterproofing membrane, while the cover 94 moves downward to cover the waterproofing membrane. The downward movement of the cover 94 drives the friction rod 910 downward to contact the surface of the waterproofing membrane. The elastic force of the spring 5 (99) ensures that the friction rod 910 always maintains close contact with the surface of the waterproofing membrane, ensuring that the friction rod 910 subsequently rubs the surface of the waterproofing membrane effectively. The heating tube 10 is then controlled to heat and dry the waterproofing membrane, shortening waiting time and improving work efficiency. The servo motor 96 is then controlled to drive the outer diamond rod 97 to rotate the inner diamond rod 98. The rotation of the inner diamond rod 98 drives the friction rod 910 to rotate, rubbing the surface of the waterproofing membrane. The friction rod 910 can also rotate as the inner diamond rod 98 rotates to rub the surface of the waterproofing membrane. This simulates the wear and tear of the waterproof membrane during actual use, effectively simulating the waterproof membrane's anti-permeation performance under real-world wear and tear conditions. This not only further improves the accuracy and reliability of the waterproof membrane's anti-permeation performance test, but also more realistically and objectively reflects the actual anti-permeation performance of the waterproof membrane after wear and tear in actual use. When the waterproof membrane is worn to an appropriate degree, the two drive members 2 95 are controlled to operate, driving the upper and lower lifting plates 2 92 on the left side away from each other, thereby driving the support ring 93 and the cover body 94 away from each other. Water and air are then supplied to the upper detection tube 4 to perform a secondary anti-permeation performance test on the waterproof membrane.

[0036] Observing the waterproof membrane for water seepage only by the naked eye is not accurate enough and affects the detection accuracy. To improve the accuracy of the detection, please refer to Figure 10 A through opening is opened in the middle of the bottom of the lower detection cylinder 6, and a transparent cover 14 is installed in the through opening. The bottom of the lower detection cylinder 6 is connected to a fixing seat 12, and a camera 13 located just below the transparent cover 14 is installed on the fixing seat 12.

[0037] The camera 13 captures images of the waterproof membrane in real time and transmits the image information to the background terminal, which analyzes the image and automatically identifies whether there is water seepage in the waterproof membrane, replacing manual visual observation, and can achieve a more accurate anti-penetration performance evaluation, thereby significantly improving the accuracy and reliability of the anti-penetration performance detection of the waterproof membrane.

[0038] See also Figure 8A telescopic tube 11 is connected to the top right side of the housing 94. This tube extends beyond the upper detection tube 4 and is connected to an external vacuum device. As the friction rod 910 rotates and wears the waterproofing membrane, the vacuum device is controlled to effectively extract dust generated during the wear process and transport it to a designated discharge or collection area. This not only helps maintain a clean test environment but also prevents dust from adhering to the surface of the waterproofing membrane, thereby preventing dust from interfering with the test results. This further improves the accuracy and reliability of the waterproofing membrane's anti-penetration performance test.
