[0002] As a key material for protecting outdoor steel structures such as ships, bridges, buildings, and vehicles, the long-term durability of anti-corrosion coatings directly determines the safety and economy of the project, thus becoming a core quality evaluation indicator in the industry. In the natural environment, solar radiation, especially ultraviolet (UV) radiation, has a significant photodegradation effect, which can lead to the breakage of coating molecular chains, causing various aging phenomena such as chalking, loss of gloss, discoloration, and cracking, greatly reducing its protective performance. At the same time, environmental factors such as temperature, humidity, and salt spray, combined with sunlight, form a complex synergistic effect, further accelerating the corrosion process and failure rate of the coating, and significantly shortening its actual service life.

[0003] Although some composite testing equipment has appeared on the market, its overall structure is complex. This means that a lot of time needs to be spent on installing anti-corrosion coatings and sealing the overall testing environment before testing. This is not only time-consuming and labor-intensive, but also complicated to operate. At the same time, the internal testing systems, such as light and hydrochloric acid, are fixed installations, which can lead to problems such as uneven light distribution and local overheating of the sample holder, affecting the uniformity, repeatability and accuracy of the test.

[0004] Based on this, a simulated light irradiation testing device for anti-corrosion coatings is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-4 As shown, a simulated light detection device for anti-corrosion coatings includes a device platform 1. A lifting component is provided on one side of the upper surface of the device platform 1, and a detection box 10 is provided on one side of the lifting component. A corresponding detection component is provided inside the detection box 10. The lifting assembly includes a lifting column 4, a first motor 6 is provided at the lower end of the lifting column 4, a sliding groove 5 is provided on one side of the lifting column 4, a threaded rod 7 is provided inside the lifting column 4, the threaded rod 7 is driven by the first motor 6, a slider 8 is threadedly connected to the threaded rod 7, one end of the slider 8 is slidably disposed on one side of the sliding groove 5 and fixedly connected to an mounting plate 9, one end of the mounting plate 9 is fixedly connected to a detection box 10, and an installation assembly is provided directly below the detection box 10; In this embodiment, the first motor 6 is started, driving the threaded rod 7 inside the lifting column 4 to rotate. The slider 8, which forms a threaded transmission with the threaded rod 7, then generates axial displacement. The slider 8 is constrained by the sliding groove 5 on one side, so it can only slide up and down along the lifting column 4. The slider 8 drives the detection box 10 to move synchronously as a whole through the mounting plate 9. When it is necessary to place a sample, the first motor 6 is controlled to raise the detection box 10, exposing the mounting components below. After the sample is placed, the detection box 10 is controlled to lower, so that its lower end docks with the sealing seat 15 on the mounting components, forming a sealed detection environment to prepare for subsequent testing.

[0023] In one embodiment, such as Figure 3 As shown, the installation assembly includes a testing platform 14, which is fixedly connected to the middle of the upper surface of the device platform 1. A sealing seat 15 is provided on the upper surface of the testing platform 14. A rotating component is provided in the middle of the testing platform 14. A liquid accumulation tank 23 is provided on the upper surface of the testing platform 14. A wastewater pipe 19 is fixedly connected to the lower end of the liquid accumulation tank 23. Waste liquids generated during the testing process, such as condensate and salt spray after spraying, will flow into the liquid accumulation tank 23 on the surface of the testing platform 14 and finally be discharged through the wastewater pipe 19 connected to the lower end of the liquid accumulation tank 23 to keep the inside of the equipment clean.

[0024] In one embodiment, such as Figure 3 As shown, the sealing seat 15 is slidably connected to the lower end of the detection box 10. A sealing gasket is provided on the inner side of the sealing seat 15. The detection platform 14 is fixed on the device platform 1. The sealing seat 15 on it is a protruding or grooved structure with a sealing gasket embedded on the inner side. When the detection box 10 is lowered under the drive of the lifting component, its lower end is accurately inserted into or covered on the sealing seat 15, and a reliable seal is achieved by squeezing the sealing gasket.

[0025] In one embodiment, such as Figure 3 As shown, the rotating assembly includes a placement frame 16. Two placement frames 16 are symmetrically arranged on both sides of the middle of the testing platform 14. Each of the two placement frames 16 has a mounting seat 18 rotatably mounted on an adjacent side. A second motor 17 is mounted on the upper end of one placement frame 16. The mounting seat 18 on one side of the placement frame 16 is driven by the adjacent second motor 17. The two mounting seats 18 are used to mount and clamp the sample to be tested. Starting the second motor 17 can drive one of the mounting seats 18 connected to it to rotate. Since the two mounting seats 18 support a sample together, when one rotates, it will drive the entire sample to rotate slowly 360 degrees. This movement ensures that the distance and angle between each part of the sample and the detection lamp 21, heating lamp 22 and water mist nozzle 20 on the top of the testing box 10 are constantly changing, so that the effects of light heating and salt spraying are more uniform, avoiding the test deviation caused by fixed placement.

[0026] In one embodiment, such as Figure 4 As shown, the detection assembly includes a water mist nozzle 20, and several water mist nozzles 20 are respectively arranged on both sides of the top of the detection chamber 10. Several detection lamps 21 are arranged on the top of the detection chamber 10, and a heating lamp 22 is arranged on the top of the detection chamber 10. The detection lamps 21 are UV lamps used to simulate ultraviolet radiation in sunlight; the heating lamps 22 are used to increase the temperature inside the detection chamber 10 to simulate a high-temperature environment.

[0027] In one embodiment, such as Figure 4 As shown, a hydrochloric acid tank 11 is installed on one side of the upper surface of the device platform 1. A water pump 12 is installed inside the hydrochloric acid tank 11. A water pipe 13 is fixedly connected to the output end of the water pump 12. The other end of the water pipe 13 passes through one side of the test chamber 10 and is fixedly connected to the input end of each water mist nozzle 20. The water mist nozzles 20 are used to spray salt mist. The salt mist is provided by the hydrochloric acid tank 11. The water pump 12 inside operates to pump the corrosive solution through the water pipe 13 to each water mist nozzle 20, which is then atomized and sprayed out. These components work together to synchronously or alternately generate various aging factors such as light, high temperature, high humidity, and salt mist in the sealed test chamber 10, thereby accelerating the corrosion test on the sample.

[0028] In one embodiment, such as Figure 1 As shown, a controller 3 is installed on one side of the upper surface of the device platform 1. The controller 3 is electrically connected to the mounting component, the detection component, and the lifting component. The controller 3 serves as the control center of the entire device and is connected to all electrical components, including the first motor 6, the second motor 17, the water pump 12, the detection lamp 21, and the heating lamp 22. The user sets the test program through the controller 3, which then automatically controls the lifting component to complete the lifting and lowering, controls the rotating component to rotate at a uniform speed, and controls the start / stop and working intensity of each component of the detection component, achieving fully automated testing.

[0029] In one embodiment, such as Figure 1 As shown, the lower surface of the device platform 1 is provided with several support legs 2. The support legs 2 on the lower surface of the device platform 1 are used to support the entire device, keep it stable, and provide space for the bottom pipeline.

[0030] The above embodiment discloses a simulated light detection device for anti-corrosion coatings. When the first motor 6 is started, it drives the threaded rod 7 inside the lifting column 4 to rotate. The slider 8, which forms a threaded transmission with the threaded rod 7, then undergoes axial displacement. One side of the slider 8 is constrained by the sliding groove 5, so it can only slide up and down along the lifting column 4. The slider 8 drives the detection box 10 to move synchronously through the mounting plate 9. When a sample needs to be placed, the first motor 6 is controlled to raise the detection box 10, exposing the mounting assembly below. After the sample is placed, the detection box 10 is controlled to descend, so that its lower end aligns with the sealing seat 15 on the mounting assembly, forming a sealed detection environment to prepare for subsequent testing. The detection platform 14 is fixed to the device platform 1. The sealing seat 15 on it is a protruding or recessed structure with a sealing gasket embedded inside. When the detection box 10 descends under the drive of the lifting assembly, its lower end accurately inserts into or covers the surface. A reliable seal is achieved by squeezing the sealing gasket on the sealing seat 15. Waste liquids generated during the testing process, such as condensate and salt spray that falls after spraying, will flow into the liquid collection tank 23 opened on the surface of the testing platform 14. Finally, they will be discharged through the wastewater pipe 19 connected to the lower end of the liquid collection tank 23 to keep the inside of the equipment clean. Two mounting seats 18 are used to install and clamp the sample to be tested. Starting the second motor 17 can drive one of the mounting seats 18 connected to it to rotate. Since the two mounting seats 18 support a sample together, when one rotates, it will drive the entire sample to rotate slowly 360 degrees. This movement ensures that the distance and angle between each part of the sample and the testing lamp 21, heating lamp 22 and water mist nozzle 20 on the top of the testing box 10 are constantly changing, so that the effect of light heating and salt spraying is more uniform and the test deviation caused by fixed placement is avoided.

[0031] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
