Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing instrument technology, and in particular to an automatic constant pressure and steady flow hydrophobicity testing instrument device. Background Technology
[0002] In the field of modern materials research and development and quality testing, automated constant-pressure, steady-flow hydrophobicity testing equipment plays a crucial role. As various industries continuously increase their requirements for the hydrophobic properties of materials, from protecting building exterior wall materials from rainwater erosion to waterproofing electronic equipment to ensure its stable operation, accurately assessing the hydrophobic characteristics of materials has become a key link in ensuring product quality and safety. This testing instrument provides a quantitative assessment of the hydrophobic properties of materials by simulating the impact of water flow in a real environment. It is widely used in the quality control processes of research institutions and manufacturing enterprises, promoting the development and innovative application of materials science.
[0003] Existing automated constant-pressure steady-flow hydrophobicity testing devices typically employ a relatively simple material placement platform in terms of mechanical structure, relying on manual adjustment and initial fixation of the material's position. The water jet system consists of a pressure pump, pipes, and nozzles. The pressure pump generates stable pressure, causing water to flow through the pipes and be ejected from the nozzles, impacting the material placed on the platform. The detection system uses a fixed-position camera to capture the interaction between the water flow and the material surface, and then uses image analysis software to process the acquired images and calculate the material's hydrophobicity parameters.
[0004] However, this existing technology has significant drawbacks in the material fixation process. During testing, when a pressurized water flow continuously washes over the material, the material is prone to displacement, especially for materials with irregular shapes. Ordinary placement platforms cannot provide stable support, causing the material to shift and sway under the impact of the water flow. This instability causes a deviation between the water flow and material interaction captured by the camera, which in turn affects the image analysis software's calculation of key parameters such as water droplet contact angle, water film formation, and diffusion. Ultimately, this leads to a significant reduction in detection accuracy, failing to accurately reflect the material's true hydrophobic properties and severely impacting the reliability and validity of the test results. To address these issues, an automatic constant-pressure, steady-flow hydrophobicity testing device is proposed. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1-3 An embodiment of this utility model is provided: an automatic constant pressure and steady flow hydrophobicity tester device, including an operation box 1, a support frame 10 fixedly connected to the bottom of the inner wall of the operation box 1, a placement box 11 fixedly connected to one side of the support frame 10, a fixing component provided on the inner wall of the placement box 11, a fixing frame 9 fixedly connected to one side of the support frame 10, and a water spraying component provided on one side of the fixing frame 9.
[0034] The fixing assembly includes multiple positioning rollers 16 located on the inner wall of the placement box 11. The positioning rollers 16 are used to roll against the material surface to reduce frictional resistance. Multiple fixing seats 12 are fixedly connected to one side of the inner wall of the placement box 11. The fixing seats 12 are used to mount slides 14 and provide sliding tracks. Each fixing seat 12 has a slide 14 slidably connected inside. The slide 14 is used to drive the positioning rollers 16 to move laterally to accommodate materials of different sizes. Each fixing seat 12 has a threaded fixing bolt 13 connected to its inner wall. The fixing bolt 13 is used to lock the position of the slide 14 within the fixing seat 12. Each slide 14 has a rotating shaft 2 rotatably connected inside. 8. The second rotating shaft 28 is used to support the connecting frame 15 and allow it to rotate. Each second rotating shaft 28 has a connecting frame 15 fixedly connected to both ends. The connecting frame 15 is used to connect multiple positioning rollers 16 to form a positioning structure. The adjacent connecting frames 15 are rotatably connected to the two ends of multiple positioning rollers 16. The rotation of the positioning rollers 16 can adapt to changes in the shape of the material surface. The outer wall of the top connecting frame 15 is provided with a positioning assembly, which includes multiple second connecting posts 19. The second connecting posts 19 are used to press the top of the material from above. Each second connecting post 19 is located on one side of the top connecting frame 15. The outer wall of the top connecting frame 15 is fixedly connected with a first connecting post 17. 17 is used to accommodate and guide connecting post 19. Each connecting post 17 has a spring 18 on its inner wall, which provides downward pressure to the connecting post 19. One end of each spring 18 is fixedly connected to the outer wall of the connecting post 19. Each connecting post 19 is slidably connected to the inner wall of the connecting post 17, and the sliding stroke of the connecting post 19 is determined by the material thickness. The other end of each spring 18 is fixedly connected to the top of the inner wall of the connecting post 17. The water spray assembly includes a spray head 8 for spraying liquid onto the material surface. A connecting block 2 7 is fixedly connected to one side of the spray head 8, connecting the spray head 8 and the fixed block 2 7. The frame 9 and the connecting block 2 7 are slidably connected to the outer wall of the fixed frame 9. The fixed frame 9 is used to support the spray head 8 and allow it to move. The bottom of the operation box 1 is fixedly connected to the water tank 2, which is used to store the working liquid. The bottom of the inner wall of the water tank 2 is fixedly connected to the suction pump 5, which is used to provide liquid delivery power. The output end of the suction pump 5 is fixedly connected to the delivery pipe 6, which is used to deliver the liquid to the spray head 8. One end of the delivery pipe 6 is fixedly connected to the inside of the connecting block 2 7. A camera 4 is set on one side of the spray head 8. The camera 4 is used to monitor the material positioning status. An adjustment component is set on the top of the camera 4, which is used to adjust the shooting height of the camera 4.
[0035] Specifically, during the material fixing process, the material is placed on the inner wall of the placement box 11. The size of the placement box 11 must match the material specifications. Then, the slide 14 is pushed to slide inside the fixed seat 12. The moving distance of the slide 14 is determined according to the width of the material, so that the positioning roller 16 moves to the outer wall of the material. The number of positioning rollers 16 affects the fixing stability. The outer wall of the material is used to push the positioning roller 16 to rotate around the rotating shaft 28 as the center, so that the positioning roller 16 accurately fits the irregular surface of the outer wall of the material. The top of the material pushes the connecting column 19 to slide inside the connecting column 17, so that the spring 18 is compressed. The telescoping characteristic of the connecting column 17 is used to make the connecting column 19 accurately fit the top of the material. The guiding accuracy of the connecting column 17 affects the positioning accuracy, ultimately enhancing the fixing effect of the equipment on the material position.
[0036] Reference Figure 2 and Figure 4 The adjustment assembly includes a slider 27, whose bottom is fixedly connected to the top of the camera 4. The slider 27 is used to drive the camera 4 to move vertically. A fixing plate 20 is slidably connected to the outer wall of the slider 27, providing a track and support for the slider 27. The fixing plate 20 is internally fixedly connected to the outer wall of the spray head 8. A fixing block 21 is fixedly connected to the top of the fixing plate 20, connecting and supporting the connecting shell 22. The connecting shell 22 is fixedly connected to the inner wall of the fixing block 21, accommodating and guiding the connecting column 25. The connecting column 25 is slidably connected to the inner wall of the connecting shell 22, transmitting the rotational motion of the rotating shaft 26. One end of the connecting column 25 is internally fixedly connected to... There is a rotating shaft 26, which is used to convert the rotational motion of the connecting block 3 into linear motion. The outer wall of the rotating shaft 26 is rotatably connected to the connecting block 3, which is used for manual operation to achieve the adjustment function. The connecting block 3 is in contact with the connecting shell 22. The other end of the connecting post 25 is fixedly connected to the locking post 23, which is used to lock the position of the slider 27. The locking post 23 is slidably connected to the inner wall of the connecting shell 22. One end of the locking post 23 is engaged with the inside of the slider 27. Each connecting post 25 is provided with a spring 24 on its outer wall. The spring 24 is used to provide the restoring force of the locking post 23. One end of the spring 24 is fixedly connected to the outer wall of the locking post 23, and the other end of the spring 24 is fixedly connected to one side of the inner wall of the connecting shell 22.
[0037] Specifically, during the height adjustment of camera 4, rotating connecting block 13 by 90 degrees causes the pivot 126, located on one side of the center point of connecting block 13, to achieve motion conversion due to its eccentric design. This pivot 126 then moves the locking pin 23 at one end of connecting column 325 out of the inner wall of slider 27, pushing spring 24 to compress it. Subsequently, slider 27 slides on the inner wall of fixed plate 20, thus allowing targeted height adjustment of camera 4. This ensures that camera 4 can comprehensively detect material surfaces of different sizes, covering key areas of the material. Then, connecting block 13 is rotated 90 degrees again, in the opposite direction to the unlocking, causing locking pin 23 to re-lock onto the inner wall of slider 27. The locking of locking pin 23 must be secure and reliable. The rebound force of spring 24 pushes locking pin 23 into full engagement with the inner wall of slider 27, achieving a fixed height for camera 4 and enhancing the applicability of the equipment.
[0038] Working principle: During the material fixing process, the material is placed on the inner wall of the placement box 11, and then the slide block 14 is pushed to slide inside the fixed seat 12, so that the positioning roller 16 moves to the outer wall of the material. The outer wall of the material pushes the positioning roller 16 to rotate around the rotating shaft 28 as the center, so that the positioning roller 16 accurately fits the irregular surface of the outer wall of the material. The top of the material pushes the connecting column 19 to slide inside the connecting column 17, so that the spring 18 is compressed. The telescoping characteristic of the connecting column 17 is used to make the connecting column 19 accurately fit the top of the material, thus enhancing the fixing effect of the equipment on the material position.
[0039] During the height adjustment of camera 4, rotating connecting block 13 by 90 degrees causes the pivot 26, located on one side of the center point of connecting block 13, to move the locking pin 23 at one end of connecting column 3 25 out of the inner wall of slider 27. This, in turn, pushes spring 24 to compress the pin, which in turn pushes slider 27 to slide on the inner wall of fixed plate 20. This allows for targeted height adjustment of camera 4, ensuring that camera 4 can comprehensively detect material surfaces of different sizes. Once the position of camera 4 is fixed, rotating connecting block 13 by 90 degrees again causes the locking pin 23 to re-lock onto the inner wall of slider 27. The rebound force of spring 24 then pushes the locking pin 23 to fully engage with the inner wall of slider 27, achieving a fixed height for camera 4 and enhancing the applicability of the equipment.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
