Description

Technical Field

[0001] This utility model relates to the field of testing technology, specifically to a solar climate testing machine. Background Technology

[0002] A solar climate tester is a testing device that simulates natural solar radiation and climatic conditions. It is used to evaluate the aging resistance (such as fading, strength reduction, deformation, etc.) and color fastness of materials under the combined effects of long-term light exposure and temperature changes. It typically consists of a light source system, a control system, and a sample fixing system. The xenon lamp or ultraviolet lamp of the light source system simulates the solar spectrum. Combined with temperature and humidity control, a spray system, etc., it reproduces natural climatic conditions such as sunlight exposure, rain, and condensation. It can quickly obtain the aging resistance data of workpieces and is widely used in various industrial fields.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When simulating the aging resistance of workpieces in a dusty environment, the existing solar weathering test chambers need to blow air into the chamber to blow the dust inside into the air. However, after a period of simulation, fine dust can easily adhere to the light source components of the solar weathering test chamber. This fine dust can partially block the light emitted by the light source components, resulting in insufficient light intensity and affecting the accuracy of the test. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a solar climate testing machine with high testing accuracy and light source that is not easily blocked.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a solar climate test machine, comprising a machine body and an opening and closing door that is movably latched and disposed on the front of the machine body. The machine body includes an isolation shell and a power base fixedly disposed on the bottom surface of the isolation shell. The top surface of the power base is provided with a placement platform, and the inner wall of the isolation shell is also provided with a light source structure.

[0006] A further improvement is that the opening and closing door is also equipped with an observation window made of acrylic material.

[0007] A further improvement is that the opening and closing door is also equipped with a closable air pressure pipe.

[0008] A further improvement is that the bottom surface of the machine body is equipped with a movable chassis.

[0009] A further improvement is that the light source structure includes an ultraviolet lamp fixedly installed inside the isolation housing and a transparent glass ring slidably installed on the outer wall of the ultraviolet lamp. The outer wall of the ring is provided with a longitudinal rod made of transparent acrylic material, and the top end of the longitudinal rod penetrates the top surface of the isolation housing.

[0010] A further improvement is that a crossbar is fixedly connected to the top of the longitudinal bar.

[0011] A further improvement is that a pull ring is provided in the middle section of the crossbar.

[0012] A further improvement is that the ring includes a glass ring body and a cavity integrally formed within the ring body that can fit against the outer wall of the ultraviolet lamp. The top surface of the ring body is provided with a glass upper shovel block with a triangular cross-section.

[0013] A further improvement is that the bottom surface of the ring body is provided with a lower shovel block made of glass with a triangular cross-section.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When conducting sun exposure testing in a dusty environment, if dust adheres to the ultraviolet lamp and affects the irradiation intensity of the ultraviolet lamp, a longitudinal rod can be pulled on the top surface of the isolation shell to move the longitudinal rod upward. This causes the collar to move upward against the outer surface of the ultraviolet lamp. In this upward movement, the dust adhering to the surface of the ultraviolet lamp is scraped off by the collar body and the upper scraper block. At the same time, the transparent glass collar does not affect the normal diffusion of light, thus effectively ensuring the light intensity of the ultraviolet lamp during sun exposure testing and making the test results more accurate.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a solar climate tester, including a body 1 and an opening and closing door 2 that is movably latched on the front of the body 1. The body 1 includes an isolation shell 11 and a power base 12 fixedly disposed on the bottom surface of the isolation shell 11. The top surface of the power base 12 is provided with a placement platform 13. The inner wall of the isolation shell 11 is also provided with a light source structure 14. The light source structure 14 includes an ultraviolet lamp 141 fixedly disposed inside the isolation shell 11 and a transparent glass ring 142 slidably disposed on the outer wall of the ultraviolet lamp 141. The ring 142 includes glass material. The device includes a ring body 21 and a cavity 22 integrally formed within the ring body 21 that can fit against the outer wall of the ultraviolet lamp 141. The top surface of the ring body 21 has a triangular glass upper shovel block 23. The outer wall of the ring 142 has a transparent acrylic longitudinal rod 143, the top of which penetrates the top surface of the isolation shell 11. The opening / closing door 2 is also equipped with a closable air pressure pipe 5. In use, the workpiece to be subjected to sunlight exposure testing is placed on the placement platform 13 of the assembly 1, along with some sand and dust. The opening / closing door 2 is then closed, and external air is injected into the assembly through the air pressure pipe 5. Inside the isolation housing 11, gas is used to blow away sand and dust, causing the sand and dust to float inside the isolation housing 11. Power is then output through the power base 12 to the ultraviolet lamp 141 in the light source structure 14, causing the ultraviolet lamp 141 to start working and generate light, which then irradiates the workpiece on the placement platform 13. When the workpiece exhibits abnormalities such as fading, decreased strength, or deformation, the time is calculated to obtain the workpiece's anti-aging performance data. Since a large amount of sand and dust will be present inside the isolation housing 11 during testing, if dust adheres to the ultraviolet lamp 141, it may affect the irradiation intensity of the ultraviolet lamp 141. Then, the longitudinal rod 143 can be pulled on the top surface of the isolation shell 11 to move the longitudinal rod 143 upward, thereby causing the ring body 21 of the collar 142 to move upward against the outer surface of the ultraviolet lamp 141. In this way, the dust attached to the surface of the ultraviolet lamp 141 is scraped off by the ring body 21 of the collar 142 and the upper scraper block 23 during the upward movement. At the same time, the transparent glass collar 142 will not affect the normal dispersion of ultraviolet light of the ultraviolet lamp 141, thus effectively ensuring the light intensity of the ultraviolet lamp 141 during the sun exposure test, making the test results more accurate.

[0022] The opening and closing door 2 is also equipped with an acrylic observation window 3, which is beneficial for simultaneous observation during the experiment;

[0023] The bottom surface of the machine body 1 is equipped with a movable chassis 4, which makes it easier to move the testing machine.

[0024] The top of the longitudinal bar 143 is also fixedly connected to a crossbar 144, which is convenient to connect multiple longitudinal bars 143 through the crossbar 144. When multiple longitudinal bars 143, ultraviolet lamps 141 and collars 142 are provided, batch cleaning can be carried out by lifting at one time.

[0025] The crossbar 1144 is also equipped with a pull ring 145 in the middle section, which makes lifting easier and more effortless.

[0026] The bottom surface of the ring body 21 is provided with a glass-material, triangular-sectioned lower scraper block 24, which is beneficial for secondary scraping and dust removal when the ring body 21 moves downward.

[0027] The working principle of this utility model is as follows: When using this utility model, the workpiece to be tested for sun exposure is placed on the placement platform 13 of the assembly 1, along with some sand and dust. The opening and closing door 2 is closed, and an external air source is injected into the isolation shell 11 through the air pressure pipe 5. The gas blows the sand and dust, causing it to float inside the isolation shell 11. Then, power is output from the power base 12 to the ultraviolet lamp 141 of the light source structure 14, causing the ultraviolet lamp 141 to start working and generate light, which then irradiates the workpiece on the placement platform 13. When the workpiece exhibits abnormalities (such as fading, decreased strength, deformation, etc.), the time is calculated to obtain the workpiece's anti-aging performance data. Because the isolation shell 11 is used for testing... During testing, a large amount of dust will be generated. If the dust attached to the ultraviolet lamp 141 affects the irradiation intensity of the ultraviolet lamp 141, the longitudinal rod 143 can be pulled on the top surface of the isolation shell 11 to move the longitudinal rod 143 upward. This will cause the ring body 21 of the collar 142 to move upward against the outer surface of the ultraviolet lamp 141. In this way, the ring body 21 of the collar 142 and the upper scraper block 23 will scrape off the dust attached to the surface of the ultraviolet lamp 141 during the upward movement. At the same time, the transparent glass collar 142 will not affect the normal dispersion of ultraviolet light from the ultraviolet lamp 141. Therefore, the light intensity of the ultraviolet lamp 141 can be effectively guaranteed during the sun exposure test, making the test results more accurate.
