Description

Technical Field

[0001] This invention belongs to the field of testing technology, and specifically discloses a testing device for polymer waterproof materials. Background Technology

[0002] With the rapid development of construction, transportation, water conservancy, and new energy fields, the requirements for the durability and safety of engineering structures are increasing. Waterproofing materials, as a crucial functional protective layer, directly determine the lifespan and reliability of infrastructure. In recent years, the waterproofing materials field has been undergoing a profound transformation from traditional asphalt-based materials to high-performance polymer materials (such as TPO, PVC, and HDPE), reinforced composite materials, and intelligent new waterproofing materials with self-healing and environmental responsiveness properties. These new materials place higher and more complex demands on tensile strength, elongation, weather resistance, and long-term service performance. Traditional mechanical performance testing methods based on atmospheric conditions or simple immersion are no longer sufficient to comprehensively and accurately assess their failure behavior under complex hydro-stress coupling conditions.

[0003] In practical applications, waterproofing materials are often subjected to a severe environment of continuous water pressure immersion and substrate deformation (such as concrete cracking and structural settlement). For example, polyurea, water-based acrylic, and rubber asphalt coatings form continuous, seamless films. Their ability to resist substrate cracking and deformation under aqueous conditions (i.e., elongation and crack following) is a core performance indicator. Similarly, for newer materials such as polymer membrane rolls, tensile performance testing in simulated aqueous environments is a crucial technical means to evaluate their ability to effectively block moisture and follow substrate deformation without failure during their service life. However, current testing methods face a series of prominent contradictions and technical bottlenecks when implementing underwater tensile testing.

[0004] When a sample is stretched to its limit or fractures in a water-filled container, the accumulated strain energy is released instantaneously, often causing violent splashing of water within the test area. This not only jeopardizes operational safety but also severely interferes with or even completely blocks critical observations during the testing process. For the development of new materials that require studying the entire process of underwater deformation, microcrack initiation, propagation, and eventual fracture, the data is unusable.

[0005] To address the aforementioned issues, there is an urgent need for an innovative testing auxiliary device that can dynamically and reliably resolve water splashing during underwater tensile testing, while providing a continuously clean and interference-free viewing environment for the high-speed visual observation system and ensuring stable synchronization between the observation angle and the tensile process. Summary of the Invention

[0006] The purpose of this invention is to solve the problems existing in the background art, and to propose a polymer waterproof material testing device, including a testing cabinet and a transverse slide rail mechanism. A shell is fixedly installed on one side of the upper part of the testing cabinet. The transverse slide rail mechanism is fixedly installed above the testing cabinet and close to the interior of the shell. A carriage is externally driven to the transverse slide rail mechanism. A movable frame is fixedly installed at the end of the carriage away from the transverse slide rail mechanism. A testing water tank is arranged above the testing cabinet and near the movable frame. The testing water tank slides with the movable frame through an internal guide. A fixed frame is fixedly installed externally at the end of the testing cabinet near the testing water tank. Hydraulic rods are arranged inside the fixed frame and the movable frame on their adjacent sides. Upper clamps are provided at the telescopic ends of the hydraulic rods. Lower clamps are fixedly installed on the outer walls of the fixed frame and the movable frame, near the lower part of the upper clamps. A flexible protective component is provided between the fixed frame and the movable frame. A control panel is installed on one outer surface of the testing cabinet. Pressure sensors are fixedly installed externally on the hydraulic rods.

[0007] In the above technical solution, the guide component further includes a stabilizing rod, the two ends of which are fastened to the inner wall of the detection water tank, and the movable frame is slidably installed on the outside of the stabilizing rod.

[0008] In the above technical solution, the flexible protective component further includes a card seat that is symmetrically installed on the outside of the fixed frame and the movable frame and close to the bottom. A sleeve is rotatably installed between the two symmetrically arranged card seats. Multiple turns of transparent high-transparency film are wound around the outside of the sleeve corresponding to the fixed frame. The end of the transparent high-transparency film away from the fixed frame is wound with the sleeve at the movable frame through a set buckle. The sleeve on the side close to the fixed frame is an electric motor driven winding device.

[0009] In the above technical solution, the buckle includes a C-shaped clip that snaps onto the outside of the sleeve at the movable frame. A transparent high-transparency film is clipped onto one side of the C-shaped clip, and a hanger is fixedly installed on the outer wall of one of the sets of clip seats located outside the movable frame.

[0010] In the above technical solution, a camera is further installed inside one end of the bracket, a guide rod is vertically installed on the side of the testing cabinet near the fixed frame, a sleeve is fixedly sleeved on the lower outside of the guide rod, a connecting rod is provided on the outer side of the sleeve, and a sliding rod is connected to the rear end of the connecting rod away from the sleeve through a cylinder.

[0011] In the above technical solution, the recording device further includes a high-definition camera, which is fixedly embedded inside one end of the bracket, and a connector is provided inside the high-definition camera.

[0012] In the above technical solution, the slide bar is further configured in an L-shape, and a U-shaped frame is fixedly connected to one side of the external side. An assembly rod is fixedly installed inside the U-shaped frame. Springs are symmetrically arranged on the outside of the assembly rod. A sliding plate is provided at the ends of the two sets of springs that are far apart from each other. One end of the sliding plate is slidably sleeved on the outside of the assembly rod. Wiping strips are fixedly installed on the outer walls of the two sets of sliding plates that are close to each other. The two sets of wiping strips slide in contact with the upper and lower outer surfaces of the transparent high-transparency film, respectively.

[0013] In the above technical solution, further, a clamping rod is fixedly installed on one side of the outer wall of the upper clamp at both the fixed frame and the movable frame. An infrared position measuring device is provided outside the clamping rod of the fixed frame, and a marker seat for the reflective infrared position measuring device is provided outside the clamping rod of the movable frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a flexible protective component made of a transparent, high-transparency film installed between a fixed frame and a movable frame. One end of the high-transparency film is wound and housed in the fixed frame, while the other end is connected to the winding mechanism of the movable frame via a snap-fit ​​device. During testing, as the movable frame stretches away from the fixed frame, the transparent, high-transparency film is continuously pulled out from the fixed frame side and simultaneously wound onto the movable frame side, thereby forming a continuous, dynamically expanding transparent barrier above and in front of the sample. This barrier effectively accommodates and blocks water splashes generated by the energy released by the sample during loading or fracture, preventing them from splashing outside the equipment, ensuring operational safety during testing, and creating an interference-free physical environment for observation.

[0015] 2. This invention features a cylinder-driven sliding rod, U-shaped frame, assembly rod, spring, and wiping strips on one side of the moving frame to ensure the cleanliness of the transparent high-transparency film and guarantee high-quality image acquisition. The device uses the sliding rod, U-shaped frame, and assembly rod to drive two sets of symmetrically arranged wiping strips. Under the action of the springs, the two sets of wiping strips are tightly attached to the upper and lower surfaces of the transparent high-transparency film, wiping the film's surfaces as the moving frame moves. This automatically removes water stains, air bubbles, or other contaminants that may adhere to the observation area during testing, maintaining the optical clarity of the observation window and providing a stable, unobstructed observation interface for subsequent recording equipment. Furthermore, the cylinder-driven sliding rod allows the wiping strips to be moved away from the test area, saving space.

[0016] 3. This invention fixes a high-definition camera within a bracket on the side of the movable frame. Since the bracket and the movable frame are rigidly connected, the high-definition camera moves synchronously as the movable frame is driven by the transverse sliding rail mechanism. This ensures that the observation axis of the high-definition camera always follows the movement trajectory of the specimen (especially the part clamped on the movable frame), guaranteeing that the observation focus is stably locked on the test area. This achieves continuous and stable tracking of the entire tensile deformation process without relative displacement, overcoming the problem of image defocusing or loss of the observation area due to changes in viewing angle.

[0017] 4. This invention incorporates infrared position measuring devices and their reflective markers at the upper clamps of both the fixed and movable frames, forming a non-contact displacement measurement system. This design avoids direct contact interference with the water medium, enabling precise and real-time measurement of the relative displacement between the two clamps, i.e., the tensile deformation of the sample. Simultaneously, a pressure sensor is installed outside the hydraulic rod driving the clamps to directly monitor the load applied to the sample during the tensile process. This sensor data is synchronized with image data acquired by a high-definition camera, providing a complete and accurate multi-dimensional data source for analyzing the entire process of material stress deformation, crack propagation, and eventual fracture underwater.

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] like Figures 1-7 The device for testing polymer waterproof materials shown includes a testing cabinet 1 and a transverse slide rail mechanism 3. A shell 4 is fixedly installed on one side of the upper part of the testing cabinet 1. The transverse slide rail mechanism 3 is fixedly installed on the upper part of the testing cabinet 1 and close to the interior of the shell 4. A slide frame 8 is externally driven to the transverse slide rail mechanism 3. A movable frame 7 is fixedly installed at the end of the slide frame 8 away from the transverse slide rail mechanism 3. A testing water tank 6 is arranged on the upper part of the testing cabinet 1 and close to the movable frame 7. The testing water tank 6 slides with the movable frame 7 through an internal guide. A fixed frame 5 is fixedly installed on the upper part of the testing cabinet 1 and close to the testing water tank 6. A hydraulic rod 10 is arranged inside the fixed frame 5 and the movable frame 7 on the side close to each other. An upper clamp 12 is arranged at the telescopic end of the hydraulic rod 10. A lower clamp 13 is fixedly installed on the outer wall of the fixed frame 5 and the movable frame 7 and close to the lower part of the upper clamp 12. A flexible protective component is arranged between the fixed frame 5 and the movable frame 7. A control panel 2 is installed on the outer surface of one side of the testing cabinet 1. Pressure sensors 11 are fixedly installed on the outside of the hydraulic rods 10. In this embodiment, the polymer waterproof material sample is clamped at both ends between the upper clamp 12 and lower clamp 13 of the fixed frame 5 and the movable frame 7, respectively, and immersed in the liquid in the test tank 6. The test is started via the control panel 2, and the transverse slide rail mechanism 3 drives the slide 8 and the movable frame 7 to move away from the fixed frame 5, thereby applying a tensile force to the sample. During this process, the hydraulic rod 10 can apply or maintain a certain clamping force or auxiliary load as needed. The tensile force on the sample is monitored and recorded in real time by the pressure sensor 11 on the hydraulic rod 10. The flexible protective component then unfolds to dynamically isolate the entire test area.

[0023] The guide includes a stabilizer bar 9, with both ends of the stabilizer bar 9 being snapped into the inner wall of the detection water tank 6, and a movable frame 7 being slidably installed on the outside of the stabilizer bar 9; In this embodiment, when the transverse slide rail mechanism 3 drives the movable frame 7 to move, the movable frame 7 slides along the outside of the stabilizer bar 9. The stabilizer bar 9, as a rigid guide reference, bears the lateral force or torque that the movable frame 7 may generate and strictly limits its movement to its own axis. The transverse slide rail mechanism 3 provides the driving force and main direction, while the stabilizer bar 9 provides auxiliary rigid guidance. Together, they ensure that the movement of the movable frame 7 and its upper clamp 12 is highly stable and precise throughout the entire stretching process.

[0024] The flexible protective components include card holders 18 that are symmetrically installed on the outside of the fixed frame 5 and the movable frame 7 and close to the bottom. A sleeve 17 is rotatably installed between the two symmetrically arranged card holders 18. Multiple turns of transparent high-transparency film 20 are wound around the outside of the sleeve 17 corresponding to the fixed frame 5. The end of the transparent high-transparency film 20 away from the fixed frame 5 is wound with the sleeve 17 at the movable frame 7 through a set buckle. The sleeve 17 on the side close to the fixed frame 5 is a winder driven by an electric motor. In this embodiment, before testing, the transparent high-transparency membrane 20 turns are wound around the sleeve 17 of the fixed frame 5, and its free end is fixed to the sleeve 17 of the movable frame 7 by a buckle. After stretching begins, the movable frame 7 moves away from the fixed frame 5. Since the free end of the membrane is fixed to the movable frame 7, the movement of the movable frame 7 will overcome the slight resistance of the sleeve 17 at the fixed frame 5, continuously pulling the transparent high-transparency membrane 20 out from one side of the fixed frame 5. As a result, a layer of transparent membrane is always taut between the fixed frame 5 and the movable frame 7, forming a protective structure that expands synchronously with the expansion of the test area, which can effectively solve the problem of water splashes caused by tensile breakage affecting the recording of the observation device; It should be noted that after the test is completed, the sleeve 17 with an electric motor can rewind the transparent high-transparency film 20. At the same time, both outer surfaces of the transparent high-transparency film 20 are coated with a waterproof coating. The purpose is to prevent water splashes from forming prints and watermarks after wiping, thus ensuring high-definition observation in subsequent tests.

[0025] The fastener includes a C-shaped clip 19 that snaps onto the outside of the sleeve 17 at the movable frame 7. A transparent high-transparency film 20 is clipped onto one side of the C-shaped clip 19. A hanging bracket 21 is fixedly installed on the outer wall of one of the sets of clip seats 18 located outside the movable frame 7. In this embodiment, one side of the C-shaped clip 19 is designed with an adhesive area for securely clamping or fixing the free end of the transparent high-transparency film 20, thereby cooperating with the movement of the moving frame 7.

[0026] A camera is installed inside one end of the bracket 21. A guide rod 23 is vertically installed on the side of the test cabinet 1 that is close to the fixed frame 5. A sleeve 25 is fixedly sleeved on the lower part of the guide rod 23. A connecting rod 28 is provided on one side of the sleeve 25. The rear end of the connecting rod 28 away from the sleeve 25 is connected to a slide rod 26 through a cylinder 27. The camera includes a high-definition camera 22. The high-definition camera 22 is fixedly embedded inside one end of the bracket 21. A connector 24 is provided inside the high-definition camera 22. The slide rod 26 is L-shaped and a U-shaped frame 29 is fixedly connected to one side of the external side. An assembly rod 31 is fixedly installed inside the U-shaped frame 29. Springs 30 are symmetrically arranged on the upper and lower parts of the assembly rod 31. A sliding plate 32 is provided at the ends of the two sets of springs 30 that are far apart from each other. One end of the sliding plate 32 is slidably sleeved on the outside of the assembly rod 31. Wiping strips 33 are fixedly installed on the outer walls of the two sets of sliding plates 32 that are close to each other. The two sets of wiping strips 33 slide in contact with the upper and lower outer surfaces of the transparent high-transparency film 20, respectively. In this embodiment, the high-definition camera 22 moves synchronously with the moving frame 7 for continuous tracking. When it is necessary to clean the transparent high-transparency film 20 of the observation window, the cylinder 27 is activated, and the sliding rod 26 is pulled to one side of the transparent high-transparency film 20 via the connecting rod 28. The sliding rod 26 pushes the entire U-shaped frame 29 and the wiping mechanism toward the transparent high-transparency film 20, and positions the two wiping strips 33 on the upper sides of the film respectively. Under the preload of the spring 30, the upper and lower sliding plates 32 drive the wiping strips 33 to press tightly against the surface of the film. Subsequently, when the moving frame 7 moves under the drive of the transverse sliding rail mechanism 3, the entire wiping mechanism fixed on the moving frame 7 moves synchronously. Due to the pressure and relative sliding between the wiping strips 33 and the film surface, water droplets and dirt adhering to the upper and lower surfaces of the film can be scraped or wiped clean. After cleaning, the cylinder 27 can pull the wiping mechanism back, causing the wiping strips 33 to disengage from the film.

[0027] The high-definition camera 22 is connected to an external control device via connector 24, enabling subsequent image acquisition and uploading.

[0028] A clamping rod 16 is fixedly installed on one side of the outer wall of the upper clamp 12 at the fixed frame 5 and the movable frame 7. An infrared position measuring device 15 is provided outside the clamping rod 16 at the fixed frame 5, and a marker seat 14 of the reflected infrared position measuring device 15 is provided outside the clamping rod 16 at the movable frame 7. In this embodiment, during the test, the infrared position measuring device 15 on the fixed frame 5 continuously emits modulated infrared light to the marker seat 14 on the moving frame 7 and receives its reflected signal. Based on the position of the infrared spot, the infrared position measuring device 15 can calculate the straight-line distance between itself and the marker seat 14 in real time. When the moving frame 7 moves, the marker seat 14 moves accordingly, and the distance between it and the infrared position measuring device 15 changes. This change in distance is the relative displacement between the two clamps, i.e., the two ends of the sample. This displacement data is transmitted to the control device in real time, and is synchronously acquired and recorded with load and image data for subsequent calculation of key mechanical parameters such as strain and modulus.

[0029] Working Principle: First, the two ends of the polymer waterproof material sample to be tested, such as roll material or coated sheet material, are clamped between the upper clamp 12 and lower clamp 13 of the fixed frame 5 and the movable frame 7, respectively, ensuring a firm clamping. Then, sufficient water or other specified liquid medium is injected into the test tank 6 to completely immerse the sample below the water surface, simulating its actual working environment. The operator starts the equipment via the control panel 2 to perform a tensile test. The transverse slide rail mechanism 3 begins to work, driving the slide 8 and its fixed movable frame 7 horizontally away from the fixed frame 5, thereby applying a tensile load to the sample immersed in water. Simultaneously, the flexible protective component begins to operate synchronously. Specifically, the C-shaped clamp 19 fixed on the movable frame 7 pulls the free end of the transparent high-transparency membrane 20. As the movable frame 7 moves, the transparent high-transparency membrane 20 is continuously pulled out from the sleeve 17 on one side of the fixed frame 5, dynamically forming a continuous and extended transparent isolation barrier above the sample. The barrier completely encloses the entire test area, including the sample and any splashing water, effectively preventing the violent splashing water caused by the instantaneous release of energy when the sample is loaded or suddenly breaks from splashing outside the equipment. This ensures operational safety and creates a stable, interference-free environment for internal observation. The high-definition camera 22 is rigidly mounted on the bracket 21 on the side of the moving frame 7. Therefore, when the moving frame 7 moves, the high-definition camera 22 moves synchronously, and its observation axis is always aligned with the sample, especially the part near the end of the moving frame 7, achieving stable tracking without relative displacement. This ensures that the entire deformation process is continuously and clearly recorded, and the image data is transmitted to the external control device in real time via the connector 24. To ensure the cleanliness of the high-transparency transparent membrane 20 during observation, cleaning is required before testing. Before testing, cylinder 27 pushes the U-shaped frame 29 towards the already stretched membrane 20 via slide rod 26. Under the operator's reverse pressure, the two sets of sliding plates 32 move away from each other. When the wiping strip 33 covers the membrane 20, the sliding plate 32 is released, and under the pressure of spring 30, it adheres tightly to the upper and lower surfaces of the membrane 20. As the moving frame 7 moves, the wiping strip 33 slides across the membrane surface, automatically removing attached water stains, air bubbles, or contaminants, ensuring a clear and unobstructed viewing field of view for the high-definition camera 22. When cleaning is not required, cylinder 27 can drive the entire wiping mechanism to retract, avoiding interference with the test. In this state, the membrane 20 can also be flattened, preventing wrinkles during winding and stretching. Finally, after the moving frame 7 moves, the infrared position measuring device 15 located outside the fixed frame 5 can detect the distance between itself and the moving frame 7, so that the real-time elongation can be measured after the sample breaks under tension. As a result, the device can not only prevent splashing during water testing and protect the observation equipment, but also has a cleaning function, which greatly improves the safety of sample testing operations.
