Description

Technical Field

[0001] The present invention relates to the technical field of detection, and in particular to a detection device for the anti-permeability test of waterproof coiled materials. Background Art

[0002] Building waterproof materials are the material basis for waterproof projects and the main barrier to prevent rainwater intrusion and groundwater and other moisture penetration in buildings and structures. The quality of waterproof materials has a great impact on waterproof projects. Therefore, the detection of the anti-permeability performance of building waterproof materials is crucial.

[0003] After retrieval, a Chinese patent with the patent publication number CN119104478B, a waterproof coiled material performance detection device, includes: a detection cylinder for placing the waterproof coiled material to be detected; a water addition and pressurization mechanism for adding water and pressurizing the waterproof coiled material in the detection cylinder for detection; the water addition and pressurization mechanism includes a support plate, a water storage tank, a water addition airbag, a pressurization airbag and a pressurization plate; a dual-purpose air pump for pumping air or inflating the water addition airbag and the pressurization airbag; an air flow channel switching mechanism for switching the connection state between the dual-purpose air pump and the water addition airbag and the pressurization airbag. The dual-purpose air pump is connected to the air flow channel switching mechanism through a main air pipe, and the air flow channel switching mechanism is respectively connected to the water addition airbag and the pressurization airbag through a first bronchus and a second bronchus.

[0004] Although the above patent can realize the test of the anti-permeability performance of waterproof coiled materials, its design lacks the function of automatically flattening the waterproof coiled material. Since it is necessary to manually arrange the waterproof coiled material in the test area, if there are wrinkles in the waterproof coiled material before the penetration test and they are not properly treated, it will affect the accuracy of the test results. Even after being fixed, the wrinkles may cause uneven local stress distribution and may also cover up existing defects (such as air bubbles and insufficient firmness at the joints). These problems may be exacerbated under the action of tension and form new leakage points, thus affecting the reliability of the test results. Summary of the Invention

Detailed implementation manners

[0028] Please refer to Figures 1 - 4, a waterproof coiled material impermeability test detection device, comprising a base 1. On the top of the base 1, there are two left and right guide rails 1-2 installed. Between the two guide rails 1-2, there is a lifting plate 1-3 slidably arranged. A upper detection cylinder 4 is connected to the lifting plate 1-3. At the top of the base 1, a lower detection cylinder 6 located directly below the upper detection cylinder 4 is connected. Drain valve pipes 43 are connected to the front lower parts of both the lower detection cylinder 6 and the upper detection cylinder 4. A gas supply pipe 41 and a water supply pipe 42 are connected to the top of the upper detection cylinder 4. The gas supply pipe 41 is located on the right side of the water supply pipe 42. On the left guide rail 1-2, there is a driving member 1-5 for driving the lifting of the lifting plate 1-3. In a specific implementation, the driving member 1-5 can be a screw motor, an electric push rod, a cylinder, or other driving devices that can achieve precise reciprocating movement. A flattening mechanism for flattening the waterproof coiled material is arranged 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. Four mounting seats 70 are evenly spaced along the circumferential direction on the outer wall of the upper detection cylinder 4. A telescopic plate 71 is hinged to the mounting seat 70. A first spring 72 is connected between the fixed end of the telescopic plate 71 and the mounting seat 70. A second spring 73 is connected between the fixed end and the movable end of the telescopic plate 71. An upper clamping block 74 is hinged to the movable end of the telescopic plate 71. Two torsion springs 75 are symmetrically connected between the upper clamping block 74 and the movable end of the telescopic plate 71. Four guide rails 2-76 are evenly spaced along the circumferential direction on the upper part of the outer wall of the lower detection cylinder 6. A lower clamping block 77 is slidably arranged in the guide rails 2-76. The four lower clamping blocks 77 are respectively located directly below the four upper clamping blocks 74. Two third springs 78 are symmetrically connected between the lower clamping block 77 and the guide rails 2-76. The clamping parts of the upper clamping block 74 and the lower clamping block 77 are both designed as tooth-shaped structures. Compared with a smooth surface, the tooth-shaped structure can better embed into the surface of the waterproof coiled material, provide stronger gripping force, and thus clamp the waterproof coiled material more firmly.

[0029] First, place the cut sheet waterproof coiled material on the top of the lower detection cylinder 6, and then control the first driving member 5 to drive the first lifting plate 3 to drive the upper detection cylinder 4 to move downward, so as to drive the upper clamping block 74 to move downward and cooperate with the lower clamping block 77 to clamp the waterproof coiled material. When the upper clamping block 74 moves downward to cooperate with the lower clamping block 77 to clamp the waterproof coiled material, the upper clamping block 74 cannot continue to move downward. Through the supporting action of the second spring 73, the telescopic plate 71 will not contract immediately. Therefore, the upper detection cylinder 4 drives the telescopic plate 71 to continue to move downward through the mounting seat 70, so that the telescopic plate 71 swings outward, stretches the first spring 72, and further makes the upper clamping block 74 move outward. Since the clamping parts of the upper clamping block 74 and the lower clamping block 77 are both designed as tooth-shaped structures, the downward movement of the upper clamping block 74 can be inserted into the tooth-shaped structure of the lower clamping block 77. Therefore, the outward movement of the upper clamping block 74 pushes the lower clamping block 77 to move outward synchronously, stretching the third spring 78. The synchronous outward movement of the upper clamping block 74 and the lower clamping block 77 can pull the waterproof coiled material outward to flatten the waterproof coiled material, ensure that the test area of the waterproof coiled material is flat and free of wrinkles, avoid detection errors caused by wrinkles in the waterproof coiled material, thereby improving the accuracy and reliability of the anti-permeability performance detection of the waterproof coiled material, and further being able to truly and objectively reflect the actual anti-permeability performance of the waterproof coiled material. The elastic force of the torsion spring 75 can make the upper clamping block 74 remain in a horizontal state and cooperate with the lower clamping block 77 to firmly clamp the waterproof coiled material. When the lower clamping block 77 moves outward to the limit, lock the upper clamping block 74 to make the upper clamping block 74 stop moving outward continuously, and the telescopic plate 71 will stop swinging outward accordingly. Therefore, the upper detection cylinder 4 drives the mounting seat 70 to continue to move downward, so that the telescopic plate 71 contracts, compressing the second spring 73, so as to adapt to waterproof coiled materials of different thicknesses.

[0030] After the upper detection cylinder 4 moves downward and covers the lower detection cylinder 6, a sealed detection space is formed, which can avoid gas and water leakage from the detection space during the subsequent anti-permeability performance detection of the waterproof coiled material, affecting the accuracy of the detection result, maintain the required detection pressure conditions, and ensure the authenticity and reliability of the experimental data. Then, the air supply pipe 41 is externally connected to an air supply device, and the water supply pipe 42 is externally connected to a water supply device. The upper detection cylinder 4 is directly supplied with water and gas through the air supply device and the water supply pipe 42, realizing water injection and pressurization of the waterproof coiled material, thereby realizing the anti-permeability performance detection of the waterproof coiled material. Both the upper detection cylinder 4 and the lower detection cylinder 6 are made of transparent materials to facilitate checking whether the waterproof coiled material is water-permeable. If the waterproof coiled material is water-permeable, it indicates that the anti-permeability performance is unqualified; if the waterproof coiled material is not water-permeable, it indicates that the anti-permeability performance is qualified. The drain valve pipe 43 is externally connected to a hose. After the detection work is completed, first open the valve on the drain valve pipe 43 to drain the water to a suitable location, and then control the driving member 1 5 to drive the lifting plate 1 3 to drive the upper detection cylinder 4 to move upward and reset, thereby driving the mounting seat 70, the telescopic plate 71 and the upper clamping block 74 to move upward and reset, loosening the waterproof coiled material. Under the reset action of the first spring 72, the telescopic plate 71 is pulled to swing inward and reset, thereby driving the upper clamping block 74 to move inward and reset. Under the reset action of the third spring 78, the lower clamping block 77 is pulled to move inward and reset.

[0031] In actual application scenarios, waterproof coiled materials often deform due to factors such as stretching during installation and environmental stress. However, existing detection equipment often fails to simulate the stretching deformation conditions under these actual use conditions, resulting in inconsistent detection results with the performance in actual applications, thus affecting the accuracy and reliability of the detection. To solve this problem and more accurately simulate the state of waterproof coiled materials in actual use and improve the practical reference value of the detection results, please refer to Figures 5 - 7, a pulling mechanism is provided between the upper detection cylinder 4 and the lower detection cylinder 6 for pulling the waterproof coiled material to stretch. The pulling mechanism includes a third guide rail 81 and a clamping block 82. Four third guide rails 81 are circumferentially and evenly spaced and connected to the lower part of the inner wall of the upper detection cylinder 4 and the upper part of the inner wall of the lower detection cylinder 6. The clamping block 82 is slidably arranged in the third guide rail 81. The four clamping blocks 82 in the lower detection cylinder 6 are respectively located directly below the four clamping blocks 82 in the upper detection cylinder 4. The clamping part of the clamping block 82 is designed as a toothed structure. Compared with a smooth surface, the toothed structure can better embed into the surface of the waterproof coiled material and provide a stronger gripping force, so as to clamp the waterproof coiled material more firmly. A tension sensor 83 is installed on the clamping block 82 in the upper detection cylinder 4. Two magnets 84 are symmetrically and embeddedly installed on the clamping part of the clamping block 82. Two fourth springs 85 are connected between the clamping block 82 in the lower detection cylinder 6 and the third guide rail 81. A driving component is provided in the upper detection cylinder 4 for driving the clamping block 82 therein to move horizontally back and forth. The driving component includes a mounting plate 86 and a ring 87. Four mounting plates 86 are circumferentially and evenly spaced and connected to the lower part of the inner wall of the upper detection cylinder 4. Each mounting plate 86 is located between two adjacent third guide rails 81 in the upper detection cylinder 4. Two inner and outer rings 87 are rotatably connected between the four mounting plates 86. The ring 87 is located above the third guide rail 81 and the clamping block 82 in the upper detection cylinder 4. Four slotted inclined plates 88 are circumferentially and evenly spaced and connected between the two inner and outer rings 87. An L-shaped pull rod 89 is connected to each of the four clamping blocks 82 in the upper detection cylinder 4. The four L-shaped pull rods 89 are respectively located in the slots of the four slotted inclined plates 88. A stepping motor 810 is installed on the right front mounting plate 86. A gear 811 is connected to the output shaft of the stepping motor 810. An arc-shaped rack 812 is connected to the inner wall of the outer ring 87. The arc-shaped rack 812 meshes with the gear 811.

[0032] The upper detection tube 4 moves downward, driving the guide rail 3 81 and the clamping block 82 therein to move downward. After the clamping block 82 in the upper detection tube 4 moves downward, it cooperates with the clamping block 82 in the lower detection tube 6 to clamp the waterproofing membrane. At this time, the waterproofing membrane has been pulled outward and flattened by the upper clamping block 74 and the lower clamping block 77. Then, the stepping motor 810 is controlled to drive the gear 811 to rotate, thereby driving the arc-shaped rack 812 to rotate with the outer ring 87, thereby driving the slotted inclined plate 88 to rotate. The slotted inclined plate 88 rotates and drives the pull rod 89 to move the clamping block 82 in the upper detection tube 4 outward. Since the clamping block 82 is provided with a magnet 84, the clamping block 82 in the upper detection tube 4 is moved downward and locked together with the clamping block 82 in the lower detection tube 6 by the magnet 84, and then the clamping block 82 in the upper detection tube 4 moves outward to drive the clamping block 82 in the lower detection tube 6 to move outward synchronously, so as to stretch the waterproof roll material outward after flattening. The tensile deformation that it may bear in actual application is simulated, and the effective simulation of the anti-penetration performance of the waterproof roll material under actual use conditions is realized, which not only further improves the accuracy and reliability of the anti-penetration performance detection of the waterproof roll material, but also more truly and objectively reflects the actual anti-penetration performance of the waterproof roll material during long-term use. The tension sensor 83 can detect the tension of the waterproof roll material in real time. The tension sensor 83 is electrically connected to the display screen, and the tension value can be transmitted to the display screen for display, so that the inspection personnel can grasp the tension of the waterproof roll material. 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 reverse.

[0033] 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 wear and tear in actual use, and it is difficult to truly reflect the actual performance of waterproof membranes after wear and tear in actual use. In order 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 the test results, please refer to Figures 8 - 9, a friction mechanism for rubbing the surface of the waterproof coiled material is provided between the upper detection cylinder 4 and the lower detection cylinder 6. The friction mechanism includes a guide rod 91, a second lifting plate 92, a support ring 93 and a cover body 94. A support ring 93 is provided in the lower detection cylinder 6, and a cover body 94 matching the support ring 93 is provided in the upper detection cylinder 4. The diameter of the cover body 94 is smaller than the diameter of the inner ring 87. On the outer walls of the cover body 94 and the support ring 93, two left and right second lifting plates 92 are connected at intervals along the circumferential direction. On the right sides of the inner walls of the upper detection cylinder 4 and the lower detection cylinder 6, guide rods 91 are connected. The right second lifting plate 92 on the cover body 94 is slidably connected to the guide rod 91 in the upper detection cylinder 4, and the right second lifting plate 92 on the support ring 93 is slidably connected to the guide rod 91 in the lower detection cylinder 6. On the left sides of the inner walls of the upper detection cylinder 4 and the lower detection cylinder 6, second driving members 95 are installed. The second driving member 95 in the upper detection cylinder 4 is used to drive the left second lifting plate 92 on the cover body 94 to lift, and the second driving member 95 in the lower detection cylinder 6 is used to drive the left second lifting plate 92 on the support ring 93 to lift. In a specific implementation, the second driving member 95 can be a driving device capable of precise reciprocating movement such as an electric slide rail, a linear motor, a lead screw motor, an electric push rod, a cylinder, etc. In the middle of the top of the cover body 94, a servo motor 96 is installed. An outer diamond-shaped rod 97 is connected to the output shaft of the servo motor 96. The outer diamond-shaped rod 97 extends into the cover body 94 and is slidably sleeved with an inner diamond-shaped rod 98. A fifth spring 99 is connected between the inner diamond-shaped rod 98 and the outer diamond-shaped rod 97. The bottom end of the inner diamond-shaped rod 98 is rotatably connected to a friction rod 910 through a bearing. On the friction rod 910, protrusions for increasing friction are connected at intervals. An annular heating tube 10 is installed on the inner top of the cover body 94 for heating and drying the waterproof coiled material.

[0034] After completing a detection operation and draining the water in the upper detection cylinder 4 and the lower detection cylinder 6, control the two second driving members 95 to operate, so as to drive the upper and lower two second lifting plates 92 on the left to approach each other, thereby driving the support ring 93 and the cover body 94 to approach each other. The support ring 93 moves upward to support the waterproof coiled material, and after the cover body 94 moves downward, it covers the waterproof coiled material. The downward movement of the cover body 94 drives the friction rod 910 to move downward to contact the surface of the waterproof coiled material, and the elastic force of the fifth spring 99 ensures that the friction rod 910 always keeps close to the surface of the waterproof coiled material, so as to ensure the effective friction of the subsequent friction rod 910 on the surface of the waterproof coiled material. Then control the heating pipe 10 to work to heat and dry the waterproof coiled material, shorten the waiting time, and improve the work efficiency. Subsequently, control the servo motor 96 to drive the outer diamond rod 97 to drive the inner diamond rod 98 to rotate. The rotation of the inner diamond rod 98 drives the friction rod 910 to rotate to friction the surface of the waterproof coiled material. When the friction rod 910 rotates with the inner diamond rod 98 to friction the surface of the waterproof coiled material, it can also rotate itself. In this way, the state of the waterproof coiled material after experiencing wear during actual use can be simulated, and the effective simulation of the anti-permeability performance of the waterproof coiled material under actual use wear conditions is realized. This not only further improves the accuracy and reliability of the anti-permeability performance detection of the waterproof coiled material, but also more truly and objectively reflects the actual anti-permeability performance of the waterproof coiled material after wear in actual application. When the waterproof coiled material is worn to an appropriate degree, control the two second driving members 95 to operate, so as to drive the upper and lower two second lifting plates 92 on the left to move away from each other, thereby driving the support ring 93 and the cover body 94 to move away from each other, and then supply water and gas to the upper detection cylinder 4 to conduct a secondary anti-permeability performance detection on the waterproof coiled material.

[0035] It is not accurate enough to only observe whether the waterproof coiled material leaks water through the naked eye of the operator, which affects the detection accuracy. To improve the detection accuracy, please refer to Figure 10 , a through hole is opened in the middle of the bottom of the lower detection cylinder 6, a transparent cover 14 is installed in the through hole, and a fixed seat 12 is connected to the bottom of the lower detection cylinder 6. A camera 13 located directly below the transparent cover 14 is installed on the fixed seat 12.

[0036] The camera 13 captures the images of the waterproof coiled material in real time, and transmits these image information to the background terminal. The background terminal analyzes the images and automatically identifies whether there is water leakage in the waterproof coiled material, replacing the naked eye observation of the operator, and can realize a more accurate anti-permeability performance evaluation, thereby significantly improving the accuracy and reliability of the anti-permeability performance detection of the waterproof coiled material.

[0037] Please refer to Figure 8, a telescopic tube 11 is connected to the right side of the top of the cover body 94. The telescopic tube 11 extends out of the upper detection cylinder 4. Connect the external telescopic tube 11 to an air extraction device. When the friction rod 910 rotates to wear the waterproof coiled material, control the air extraction device to work, which can effectively extract the dust generated during the wear process in time and transport it to the designated emission or collection area. This not only helps to maintain the cleanliness of the test environment, but also prevents dust from adhering to the surface of the waterproof coiled material, thus avoiding interference with the test results of the waterproof coiled material due to the presence of dust, and further improving the accuracy and reliability of the anti-permeability performance test of the waterproof coiled material.
