Description

Technical Field

[0001] This application relates to the technical field of salt spray corrosion testing, and in particular to a salt spray corrosion light irradiation testing device. Background Technology

[0002] Salt spray corrosion is a common and highly destructive form of atmospheric corrosion, primarily composed of sodium chloride from the ocean, originating mainly from marine and inland saline-alkali regions. The corrosion of metallic surfaces by salt spray is caused by chloride ions penetrating the oxide and protective layers of the metal surface and undergoing an electrochemical reaction with the internal metal. This study utilizes simulated salt spray environments in test chambers to assess the corrosion resistance of metallic materials, their protective layers, or industrial products.

[0003] To accurately assess the durability of materials in complex environments, comprehensive corrosion and light exposure tests are required. Traditional methods involve separate salt spray and light exposure experiments, but these are time-consuming, labor-intensive, and fail to accurately reflect the material's performance in real-world applications. Integrated testing devices, combining multiple testing functions such as salt spraying, temperature control, and light exposure, can address this by implementing simple salt spraying or ultraviolet light irradiation tests. However, existing multi-functional salt spray corrosion and light exposure test chambers generally suffer from fixed sample placement, limiting angle adjustments and potentially leading to over-spraying or insufficient light exposure in certain areas, thus affecting the accuracy and reliability of the test results. Ensuring uniform treatment across the surface of irregularly shaped specimens is a critical challenge that urgently needs to be addressed.

[0004] In view of the above-mentioned technologies, it is necessary to propose a salt spray corrosion light irradiation test device to solve one of the above-mentioned technical problems. Summary of the Invention

[0005] To solve one of the above-mentioned technical problems, this application provides a salt spray corrosion light irradiation test device.

[0006] The salt spray corrosion light irradiation test device provided in this application adopts the following technical solution: A salt spray corrosion light exposure test apparatus includes: The box body, the top of which is provided with a light-illuminating mechanism to provide illumination light to the specimen inside the box body; A spray mechanism, disposed inside the chamber, is used to spray salt spray onto the specimen; and A support mechanism is disposed inside the housing. The support mechanism is used to support the test specimen. The support mechanism includes a support frame, several support columns, a mounting platform for supporting the test specimen, a swivel ball, a mounting plate, and an adjusting cylinder. Several support columns are disposed at preset positions on the support frame. The swivel ball is rotatably disposed on the top of the support columns. The bottom of the mounting platform is adapted to and abuts against the swivel ball to provide multi-angle rotation of the mounting platform. The mounting plate is fixed to the support columns. The adjusting cylinder is movably connected to the perimeter of the mounting plate. The output end of the adjusting cylinder is rotatably connected to one side of the bottom of the mounting platform. When the adjusting cylinder extends or retracts, it controls the multi-angle tilt adjustment of the mounting platform.

[0007] By adopting the above technical solutions, the illumination mechanism can provide stable light source conditions for the specimen, ensuring that the light intensity and wavelength meet the test requirements. At the same time, the spray mechanism can uniformly spray salt spray onto the surface of the specimen. Combined with the multi-angle adjustment function of the bearing mechanism, it can ensure that all parts of the specimen can fully contact the salt spray, thereby improving the accuracy and reliability of the test results. After the test, in order to reduce the adhesion of water droplets formed by salt spray to the specimen, the water droplets are removed from the surface of the specimen by multi-angle rotation, so that only a thin and uniform liquid film is laid on the surface of the specimen, avoiding uneven corrosion caused by excessive salt spray in some areas, so as to facilitate data collection of the specimen after the test.

[0008] Optionally, the bearing mechanism further includes several snap-fit ​​pieces and elastic elements. The snap-fit ​​pieces are arranged circumferentially along the mounting platform and can rotate relative to the mounting platform. One end of the elastic element is connected to the mounting platform, and the other end of the elastic element is connected to the bottom of the snap-fit ​​piece. Multiple snap-fit ​​pieces together clamp the specimen, and the elastic element is used to adjust the size of the retaining ring formed by the multiple snap-fit ​​pieces.

[0009] By adopting the above technical solution, stable fixation of the specimen is achieved. Specifically, the snap-fit ​​piece can automatically adjust its position under the action of the elastic element, ensuring that specimens of different shapes and sizes can be placed stably on the mounting platform, preventing the test results from being affected by vibration or movement during the test. At the same time, this design also facilitates quick replacement of specimens and improves test efficiency.

[0010] Optionally, the spraying mechanism includes a delivery pipe, several sprayers, and a spray head. The delivery pipe is disposed on the inner wall of the housing. The several sprayers are disposed on both sides of the inner wall of the housing and connected to the delivery pipe. The spray head is connected to the sprayers and is used to spray salt spray evenly. The spray head is disposed above the support frame and the support column.

[0011] By adopting the above technical solutions, the spraying mechanism can ensure that the salt spray is evenly distributed throughout the test chamber, thereby improving the accuracy and reliability of the corrosion test of the specimen. Specifically, the design of the delivery pipe and multiple sprayers allows the salt spray to enter the chamber from multiple points, avoiding the problem of excessively high or low local concentrations. The connection between the spray head and the sprayer further ensures the uniform spraying of the salt spray, so that the surface of the specimen is subjected to a consistent corrosion environment, improving the consistency and repeatability of the experimental results.

[0012] Optionally, several support columns are arranged circumferentially on the support frame or at equal intervals on the support frame, and the length of each spray head relative to the side wall of the box is adjustable for spraying the test specimen.

[0013] By adopting the above technical solution, it is possible to effectively support the specimens on the carrier frame and conduct tests on multiple specimens simultaneously, thereby improving test efficiency, enabling effective comparison, reducing test errors, and allowing the spray head to be retractable and adjustable to improve the uniformity of spraying.

[0014] Optionally, a salt spray supply mechanism is provided inside the frame. The salt spray supply mechanism includes a mixing chamber, a supply pipe, and a temperature controller. The mixing chamber is located inside the frame. One end of the supply pipe is connected to the spraying mechanism, and the other end is connected to the mixing chamber. The temperature controller is located on one side of the mixing chamber and is used to control the salt spray environment inside the mixing chamber.

[0015] By adopting the above technical solution, the salt spray corrosion light exposure test chamber can accurately control the temperature and humidity of the salt spray environment, ensuring the stability of the salt spray mixture and thus improving the accuracy and reliability of the test results. At the same time, the temperature controller can effectively prevent experimental errors caused by temperature fluctuations, making the testing process more stable and controllable.

[0016] Optionally, the frame is provided with a ventilation duct, which is connected to the housing and contains a fan; the ventilation duct is also provided with a heating mechanism and a cooling mechanism to regulate the temperature inside the housing.

[0017] By adopting the above technical solution, the ventilation duct is connected to the chamber, ensuring the airflow inside the chamber during the test and effectively avoiding test result deviations caused by salt spray accumulation. The fan further enhances the air circulation effect, improving the stability and accuracy of the test. The ventilation duct is equipped with heating and cooling mechanisms, which can effectively regulate the temperature inside the chamber, ensuring the stability and controllability of environmental conditions during the test, thereby improving the accuracy and reliability of the test results.

[0018] Optionally, a cleaning rack is slidably provided on the inner wall of the box, and a pushing mechanism is provided inside the box. The pushing mechanism is connected to the bottom end of the cleaning rack, and the cleaning rack cleans and collects salt spray droplets on the inner wall of the box by pushing the rack through the pushing mechanism.

[0019] By adopting the above technical solution, effective cleaning and collection of salt spray droplets on the inner wall of the salt spray corrosion light exposure test chamber is achieved. Specifically, the cleaning rack is slidably installed on the inner wall of the chamber, which can easily cover the entire inner wall area, ensuring cleaning without dead corners. The pushing mechanism is connected to the bottom of the cleaning rack, which can drive the cleaning rack to move along the inner wall, realizing an automated cleaning process and improving work efficiency. By scraping and collecting salt spray droplets on the inner wall, the cleaning rack effectively reduces the impact of salt spray droplets on the test results, improving the accuracy and reliability of the test data.

[0020] Optionally, a cleaning groove is provided through the top of the cleaning frame, a drive motor is provided on the outside of the cleaning frame, an adsorption cotton roller is rotatably arranged inside the cleaning groove, the output end of the drive motor is connected to one end of the adsorption cotton roller, and the outer surface of the adsorption cotton roller is in contact with the inner wall of the box for adsorbing salt spray water droplets on the inner wall of the box.

[0021] By adopting the above technical solution, the adsorption cotton roller on the cleaning rack can effectively adsorb salt spray water droplets on the inner wall of the chamber, preventing water droplet accumulation from affecting the accuracy of the test results; at the same time, the drive motor drives the adsorption cotton roller to rotate, ensuring that the entire inner wall is evenly stressed, improving cleaning efficiency and cleanliness.

[0022] Optionally, the outer surface of the adsorption cotton roller is provided with a plurality of grooves. When the outer surface of the adsorption cotton roller is subjected to salt spray droplets, the salt spray droplets that are overloaded are adsorbed into the interior of the adsorption cotton roller through the plurality of grooves.

[0023] By adopting the above technical solution, the outer surface of the adsorption cotton roller is provided with several grooves, which can effectively increase the adsorption area and adsorption capacity, making the adsorption cotton roller more efficient in adsorbing salt spray droplets. When too many salt spray droplets accumulate on the surface of the adsorption cotton roller, the excess salt spray droplets can be further adsorbed into the interior of the adsorption cotton roller through these grooves, thereby avoiding the problem of reduced cleaning efficiency due to adsorption saturation and improving the reliability and continuity of the entire cleaning process.

[0024] Optionally, the cleaning rack is provided with a shovel plate on the side near the inner wall of the box. The shovel plate is " / " shaped, and the inclined top side of the shovel plate is attached to the inner wall of the box. A guide groove is provided through the side of the cleaning rack near the shovel plate and communicates with the cleaning groove.

[0025] By adopting the above technical solutions, the scraper can effectively remove large particles of salt spray deposits on the inner wall of the chamber, improving cleaning efficiency and thoroughness; the design of the guide channel allows the scraped salt spray droplets to be smoothly guided into the cleaning channel, further enhancing the cleaning effect and ensuring that the inner wall of the chamber remains clean.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting multiple support columns and universal balls in the bearing mechanism and using adjusting cylinders to adjust the mounting platform at multiple angles, not only can the specimen be uniformly sprayed with salt spray at different angles, but also the excessive corrosion of some areas caused by uneven force at a single angle can be effectively avoided, thereby improving the authenticity and accuracy of the test results. In addition, the snap-fit ​​pieces and elastic components mounted on the mounting platform can firmly fix the specimen and prevent it from shifting or falling off during multi-angle adjustment, ensuring the safety and stability of the test process. 2. The spraying mechanism adopts a design with a guide pipe, multiple sprayers and spray heads, which can spray salt spray evenly and ensure that all parts of the specimen surface are fully and consistently sprayed. This solves the problem of difficulty in achieving uniform spraying of large-sized specimens or multiple batches of specimens in the existing technology. The illumination mechanism, by setting up light fixtures and filters, can simulate the illumination conditions in the natural environment, providing a more realistic illumination environment for the specimens, and further improving the effectiveness and reliability of the test.

[0035] The following is in conjunction with the accompanying drawings. Figures 1-7 This application will be described in further detail.

[0036] Example 1, Reference Figure 1 and Figure 5 This application discloses a salt spray corrosion light exposure test device, including: a box 1, a spraying mechanism 2 and a supporting mechanism 3.

[0037] The top of the chamber 1 is equipped with a light-emitting mechanism 12 that provides illumination to the specimens inside the chamber 1; a spray mechanism 2 is located inside the chamber 1 and is used to spray salt spray onto the specimens; a support mechanism 3 is located inside the chamber 1 and is used to support the specimens. The support mechanism 3 includes a support frame 31, several support columns 32, a mounting platform 33 for supporting the specimens, a universal ball 34, a mounting plate 35, and an adjusting cylinder 36. Several support columns 32 are located at preset positions on the support frame 31. The universal ball 34 is rotatably mounted on the top of the support columns 32. The bottom of the mounting platform 33 is adapted to and supports the universal ball 34 to provide multi-angle rotation of the mounting platform 33. The bottom of the mounting platform 33 is provided with a concave surface to allow the angle of the universal ball 34 to change. The mounting plate 35 is fixed to the support columns 32. The adjusting cylinder 36 is movably connected to the four sides of the mounting plate 35. The output end of the adjusting cylinder 36 is rotatably connected to one side of the bottom of the mounting platform 33. When the adjusting cylinder 36 extends or retracts, it controls the multi-angle tilt adjustment of the mounting platform 33.

[0038] The illumination mechanism 12 provides stable light source conditions for the specimen, ensuring that the light intensity and wavelength meet the test requirements, simulating solar radiation and providing an environment that closely matches actual needs. Simultaneously, the spray mechanism 2 can uniformly spray salt mist onto the specimen surface. Combined with the multi-angle adjustment function of the support mechanism 3, this ensures that all parts of the specimen are fully in contact with the salt mist. Specifically, by setting multiple support columns 32 and universal balls 34 in the support mechanism 3, and using the adjusting cylinder 36 to adjust the mounting platform 33 at multiple angles, not only is uniform salt mist spraying achieved on the specimen at different angles, but excessive corrosion in some areas due to uneven force at a single angle is also effectively avoided, thereby improving the accuracy and reliability of the test results. After the test, to reduce the adhesion of water droplets formed by the salt mist to the specimen, multi-angle rotation causes the water droplets to fall off the specimen surface, resulting in only a thin, uniform liquid film on the specimen surface. This avoids uneven corrosion caused by excessive salt mist in some areas, facilitating data collection from the specimen after the test.

[0039] refer to Figure 1 and Figure 4 In this embodiment, more specifically, the supporting mechanism 3 also includes several snap-fit ​​pieces 37 and elastic elements 38.

One end of the elastic element 38 is connected to the mounting platform 33, and the other end of the elastic element 38 is connected to the bottom of the snap-fit ​​piece 37. The elastic element 38 is a spring. The multiple snap-fit ​​pieces 37 together clamp the specimen. The elastic element 38 is used to adjust the size of the retaining ring formed by the multiple snap-fit ​​pieces 37, thereby achieving stable fixation of the specimen. Specifically, the snap-fit ​​pieces 37 can automatically adjust their position under the action of the elastic element 38 to ensure that specimens of different shapes and sizes can be stably placed on the mounting platform 33, preventing the test results from being affected by vibration or movement during the test. At the same time, this design also facilitates quick replacement of specimens and improves test efficiency.

The delivery pipe 21 is disposed on the inner wall of the chamber 1. The several sprayers 22 are disposed on both sides of the inner wall of the chamber 1 and connected to the delivery pipe 21. The spray head 23 is connected to the sprayers 22 and is used to uniformly spray the salt mist. The spray head 23 is disposed above the support frame 31 and the support column 32. The spraying mechanism 2 can ensure that the salt mist is uniformly distributed throughout the test chamber, thereby improving the accuracy and reliability of the corrosion test of the specimen. Specifically, the design of the delivery pipe 21 and the multiple sprayers 22 allows the salt mist to enter the chamber 1 from multiple points, avoiding the problem of excessively high or low local concentrations. The connection between the spray head 23 and the sprayers 22 further ensures the uniform spraying of the salt mist, so that the surface of the specimen is subjected to a consistent corrosion environment, improving the consistency and repeatability of the experimental results.

[0041] In this embodiment, more specifically, several support columns 32 are arranged circumferentially on the support frame 31 or at equal intervals on the support frame 31. The length of each spray head 23 relative to the side wall of the box 1 is adjustable for spraying the test specimen. It can be effectively supported on the support frame 31 and multiple test specimens can be tested simultaneously, improving test efficiency, enabling effective comparison, and reducing test errors. The spray head 23 is adjustable to improve the uniformity of spraying.

The optical instrument 121 is disposed on the top of the housing 1 and extends into the housing 1. The filter 122 is disposed on the illumination surface of the optical instrument 121. The illumination mechanism 12 can effectively simulate different types of light source conditions, ensuring the stability and controllability of light intensity and wavelength during the experiment. The application of the filter 122 can further filter out unnecessary light components, improving the accuracy and reliability of the experimental results.

The salt spray supply mechanism 4 includes a mixing chamber 41, a supply pipe 42, and a temperature controller 43. The mixing chamber 41 is located inside the frame 11. One end of the supply pipe 42 is connected to the spraying mechanism 2, and the other end is connected to the mixing chamber 41. The temperature controller 43 is located on one side of the mixing chamber 41 and is used to control the salt spray environment inside the mixing chamber 41. An air compressor 44 and a filter 45 are provided on one side of the temperature controller 43 to guide the external air environment into the mixing chamber 41. A salt spray generator 46 is provided inside the frame 11 to generate salt spray. The air introduced into the mixing chamber 41 is mixed with the externally regulated air and then conveyed to the delivery pipe 21 for spraying. The temperature controller 43 uses existing temperature and humidity control products to effectively regulate the external air environment so that the air environment entering the mixing chamber 41 is suitable for salt spray test simulation. This salt spray corrosion light test chamber can accurately control the temperature and humidity of the salt spray environment to ensure the stability of the salt spray mixture, thereby improving the accuracy and reliability of the test results. At the same time, the temperature controller 43 can effectively prevent experimental errors caused by temperature fluctuations, making the test process more stable and controllable.

The adsorption cotton roller 63 on the cleaning frame 6 can effectively adsorb salt spray water droplets on the inner wall of the box 1, preventing water droplet accumulation from affecting the accuracy of the test results. At the same time, the drive motor 62 drives the adsorption cotton roller 63 to rotate, ensuring that the entire inner wall is evenly stressed, improving cleaning efficiency and cleanliness.
