Description

Technical Field

[0001] This invention relates to the field of weather resistance testing devices, specifically to a weather resistance testing device for artificial turf and its usage method. Background Technology

[0002] Currently, the industry commonly uses artificial climate aging test chambers to accelerate the weathering resistance testing of artificial turf samples, with ultraviolet aging test chambers being the mainstream equipment. This type of equipment simulates and intensifies ultraviolet radiation from sunlight, combined with temperature and humidity control, to rapidly evaluate the anti-aging performance of materials in the laboratory.

[0003] Patent publication number CN214174107U relates to the field of weather resistance testing devices. It includes a base, a control mechanism, a light radiance mechanism, a water spraying mechanism, and a heating mechanism. The control mechanism is located on the lower inner side of the base, while the light radiance mechanism, water spraying mechanism, and heating mechanism are evenly distributed on the upper part of the base. The lower part of the base is a cylindrical support, with a horizontal cantilever on one side of the support. A vertical pole is attached to the end of the cantilever, and a control panel is located at the top of the vertical pole. A display and buttons are located in front of the control panel. The technical solution proposed in this patent achieves excellent results: the artificial turf weather resistance testing device uses the light radiance mechanism, water spraying mechanism, and heating mechanism located on the upper part of the base to conduct comprehensive testing of the artificial turf on the testing platform under ultraviolet radiation, water spraying and compaction, and strong hot air blowing. It completes comprehensive weather resistance data in a very short time, providing accurate data for artificial turf and ensuring production and sales.

[0004] The aforementioned patent completes comprehensive weather resistance data in a very short time, providing accurate data for artificial turf. In current artificial turf weather resistance testing technology, although traditional devices can conduct aging tests on turf samples through ultraviolet irradiation, there are significant operational and maintenance defects in actual use. When placing samples into the testing chamber, manual fixing or simple clamping is usually required, which is not only inefficient but also makes it difficult to ensure consistent tightness each time. This can easily lead to local warping, displacement, or even separation of the sample from the preset irradiation area due to temperature changes, internal airflow, or equipment vibration during the test, seriously affecting the uniformity of ultraviolet irradiation and the reliability of aging data. After each ultraviolet accelerated aging test, debris generated from the degradation of the turf surface remains in the testing chamber. If this debris is not removed in time, it will adhere to the surface of subsequent new samples or deposit on key optical components such as ultraviolet lamps and reflectors, resulting in spectral intensity attenuation and uneven temperature distribution, seriously interfering with the stability and repeatability of the testing environment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an artificial turf weather resistance testing device and its usage method, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a weather resistance testing device for artificial turf, comprising a testing cabinet, a cabinet door, a placement platform, a sliding frame, and an ultraviolet lamp.

The sliding cover is slidably installed on the inner wall of the sliding frame. One end of the fourth connecting rod is rotatably connected to the sliding rod, and the other end of the fourth connecting rod is rotatably connected to the sliding cover.

[0014] The sealing device also includes a baffle plate and a connecting rod five. The baffle plate is slidably installed on the inner wall of the sliding frame. One end of the connecting rod five is rotatably connected to the sliding cover, and the other end of the connecting rod five is rotatably connected to the baffle plate.

[0015] The sliding block has an inclined surface on the side near the sliding frame. The inclined surface of the sliding block is to facilitate pushing the sliding frame to reset. An elastic element three is provided between the sliding frame and the testing cabinet. The elastic element three is provided to facilitate moving the sliding frame downward. The sliding cover is divided into a first cover plate and a second cover plate. The first cover plate and the second cover plate have slots inside. The shape of the slots matches the ultraviolet lamp.

[0016] The emission device includes a second fixed rod, a baffle, a rotating rod, a second connecting rod, and a long rod. The second fixed rod is slidably installed on the inner wall of the testing cabinet and is fixedly connected to the sliding frame. An exhaust hole is provided on the inner wall of the testing cabinet. The baffle is rotatably installed on the inner wall of the testing cabinet near the exhaust hole. The rotating rod is fixedly installed on the circumferential surface of the baffle's rotating shaft. One end of the second connecting rod is rotatably connected to the second fixed rod, and the other end of the second connecting rod is rotatably connected to the rotating rod.

[0018] The rotating connecting rod is a telescopic rod two. The movable end of the rotating connecting rod is rotatably connected to the cleaning rod. A ruler tooth is fixedly installed on the side of the fixed rod two near the gear, and the ruler tooth matches the gear.

[0019] A method for using an artificial turf weather resistance testing device includes the following steps:

[0020] Step 1: When the cabinet door is closed, it will move the pull rod. The movement of the pull rod will push the connecting rod to move. The movement of the connecting rod will pull the fixed rod to move. The movement of the fixed rod will cause the platform with straw to slide into the testing cabinet.

[0021] Step 2: When the lawn is inside the testing cabinet, the rotating block will rotate. When the rotating block rotates, it will press the movable plate downward. The downward movement of the movable plate will cause the lawn to slide into the placement platform. The pressing block will apply a certain pressure to the lawn so that the lawn will not warp or shift due to thermal expansion, airflow or vibration during the test.

[0022] Step 3: After the lawn is placed inside the testing cabinet, the ultraviolet lamp is moved downwards by the sliding frame to conduct ultraviolet irradiation testing on the lawn surface to detect whether it will discolor, chalk, or crack.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. In this invention, the pressure block automatically rotates to press down on the edge of the lawn, while the movable plate sinks down, so that the lawn surface is level with or slightly lower than the edge of the placement platform. This prevents the sample from warping or shifting during testing due to thermal expansion, airflow, or vibration. When the device is opened, the movable plate moves in the opposite direction to lift the sample smoothly, making it easy to remove the lawn. After each test, ultraviolet radiation will cause the sample surface to powder and degrade, producing debris. Through the first and second rotating plates, the surface debris can be discharged to the outside of the testing cabinet while the old sample is being removed, ensuring that each test is conducted in a standard, clean initial environment, and the data comparability is strong.

[0025] 2. In this invention, when the sliding cover moves, it pushes the connecting rod five to move. The movement of the connecting rod five pushes the baffle plate downward. The downward movement of the baffle plate will block the area around the ultraviolet lamp and enhance the shielding effect. The baffle plate enhances the airtightness of the test cabinet and prevents external ambient light from entering through gaps during the test, thus preventing contamination of the pure ultraviolet or simulated solar spectrum test environment. It allows ultraviolet light to be more concentrated and uniformly irradiated downward onto the sample surface, reducing disordered reflection and scattering of light in the lamp holder cavity, making the light intensity received by the sample surface more uniform and the spectrum more accurate.

[0026] 3. In this invention, linear motion is converted into rotation by teeth and gears, and then the cleaning rod is driven to scrape and clean the outer surface of the exhaust hole to ensure smooth ventilation. The unobstructed exhaust hole ensures that the exhaust rate and air exchange rate in the cabinet are basically consistent in each test. This is a key prerequisite for maintaining controllable and repeatable environmental parameters such as temperature, humidity and gas concentration. Attached Figure Description

[0038] Example 1

[0039] Please see Figures 1-8 One embodiment of the present invention is: a weather resistance testing device for artificial turf, comprising a testing cabinet 1, a cabinet door 2, a placement platform 6, a sliding frame 23, and an ultraviolet lamp 24. The cabinet door 2 is rotatably mounted on the inner wall of the testing cabinet 1, the placement platform 6 is slidably mounted on the bottom of the inner wall of the testing cabinet 1, the sliding frame 23 is slidably mounted on the inner wall of the testing cabinet 1, and the ultraviolet lamp 24 is fixedly mounted on the bottom of the sliding frame 23. Weather resistance testing device:

[0040] An active device for facilitating the removal and placement of the lawn is installed on the inner wall of the inspection cabinet 1;

[0041] A pull rod 3 is fixedly installed on the side of the cabinet door 2 near the placement platform 6. A fixed rod 5 is fixedly installed on the side of the placement platform 6 near the pull rod 3. A connecting rod 4 is movably connected between the fixed rod 5 and the placement platform 6. A sliding block 7 is slidably installed on the surface of the fixed rod 5. A rotating block 9 is rotatably installed on the inner wall of the placement platform 6. A connecting rod 8 is rotatably installed between the rotating block 9 and the sliding block 7. A movable plate 10 is slidably installed on the inner wall of the placement platform 6. A pressure block 11 is rotatably installed on the inner wall of the placement platform 6.

[0042] A sealing device for more tightly sealing the placement table 6 and the ultraviolet lamp 24 is installed on the inner wall of the testing cabinet 1.

[0043] An exhaust device for discharging exhaust gas generated inside the testing cabinet 1 during testing is installed on the inner wall of the testing cabinet 1.

[0044] The movable device includes a rotating plate 12, a rotating plate 2 13, a push plate 14, a push block 15, a lower rod 16, and an upper rod 17. The surface of the movable plate 10 has a discharge groove 1. The rotating plate 12 is rotatably installed inside the discharge groove 1. The bottom of the placement platform 6 has a discharge groove 2. The rotating plate 2 13 is rotatably installed on the inner wall of the discharge groove 2. The bottom of the inner wall of the testing cabinet 1 has a discharge groove 3. The push plate 14 is fixedly installed at the bottom of the rotating plate 2 13. The push block 15 is fixedly installed at the bottom of the inner wall of the testing cabinet 1. The lower rod 16 is fixedly installed on the side of the rotating plate 2 13 near the rotating plate 12. The upper rod 17 is fixedly installed on the side of the rotating plate 12 near the rotating plate 2 13.

[0045] A torsion spring is provided between the pressure block 11 and the placement platform 6. The torsion spring is provided to drive the pressure block 11 to rotate in the direction of the movable plate 10. An elastic element is provided between the movable plate 10 and the placement platform 6. The elastic element is provided to drive the movable plate 10 to reset. The side of the push block 15 near the push plate 14 is set with an inclined surface. The inclined surface of the push block 15 is provided to facilitate the movement of the push plate 14. A torsion spring is provided between the rotating plate 12 and the movable plate 10. The torsion spring is provided to facilitate the reset of the rotating plate 12. An elastic element is provided between the sliding block 7 and the fixed rod 5. The elastic element is provided to drive the sliding block 7 to reset.

[0046] In this embodiment, during weather resistance testing of the lawn, the lawn is placed in the placement platform 6. Then, while closing the cabinet door 2, the lawn is fed into the testing cabinet 1 via the placement platform 6. After being placed inside the testing cabinet 1, the lawn surface is irradiated with ultraviolet light 24 to detect whether discoloration, chalking, or cracking occurs. When the lawn is placed inside the placement platform 6, it is on the surface of the movable plate 10. When the cabinet door 2 is closed, it moves the pull rod 3. The movement of the pull rod 3 pushes the connecting rod 4, which in turn pulls the fixing rod 5. The movement of the fixing rod 5 causes the placement platform 6 to slide towards the inside of the testing cabinet 1. When the connecting rod 4 moves the fixing rod 5, it slides away from the placement platform 6. When the movement is complete, the pushing force on the sliding block 7 will be released, and the sliding block 7 will be driven by the elastic element 2 to slide towards the connecting rod 4. The sliding of the sliding block 7 will pull the connecting rod 8 to move, and the movement of the connecting rod 8 will push the rotating block 9 to rotate. The rotating block 9 will come into contact with the movable plate 10. Since the elastic coefficient of the elastic element 2 is greater than that of the elastic element 1, the rotating block 9 will press the movable plate 10 downward when it rotates. The downward movement of the movable plate 10 will cause the lawn to slide into the placement platform 6. The downward movement of the movable plate 10 will release the obstruction on the pressure block 11, and the pressure block 11 can rotate towards the lawn. The pressure block 11 will apply a certain pressure to the lawn, and the lawn will not move randomly. When the test is completed and the cabinet door 2 is opened to take out the lawn, the opening of the cabinet door 2 will push the pull rod 3. When the connecting rod 4 slides towards the placement platform 6, and the top of the pull rod 3 contacts the connecting rod 4, the pull rod 3 will pull the connecting rod 4 as it rotates outward. The movement of the connecting rod 4 will pull the fixed rod 5, which in turn will pull the placement platform 6 outward. At this time, the lawn will be brought out by the placement platform 6. When the connecting rod 4 moves towards the placement platform 6, it will push the sliding block 7 towards the placement platform 6. The movement of the sliding block 7 will push the connecting rod 8, which will then push the rotating block 9 to rotate. The rotation of the rotating block 9 will release the pressure on the movable plate 10, causing the movable plate 10 to slowly rise. The pressing block 11 will automatically rotate and press down on the edge of the lawn. At the same time, the movable plate 10 will sink, causing the lawn surface to drop to the edge of the placement platform 6. The sample is positioned flush with or slightly lower than the edge to prevent warping or displacement due to thermal expansion, airflow, or vibration during testing. When opened, the reverse movement of the movable plate 10 smoothly lifts the sample, facilitating the removal of the lawn. When the lawn is removed from the placement platform 6, some debris may fall inside due to prolonged UV exposure. This debris will be on the surface of the rotating plate 12. When the movable plate 10 moves upward, it will drive the rotating plate 12 to move. The movement of the rotating plate 12 will drive the upper rod 17 to move upward, and the upper rod 17 will contact the lower rod 16. When the placement platform 6 slides outward, it will drive the rotating plate 13 to move. The movement of the rotating plate 13 will drive the push plate 14 to move, and the push plate 14 will contact the inclined surface of the push block 15.Push block 15 will push push plate 14 to rotate downwards. The downward rotation of push plate 14 will cause lower rod 16 to move. The rotation of lower rod 16 will pull upper rod 17 to rotate downwards. The rotation of upper rod 17 will cause rotating plate one 12 to rotate. The downward rotation of upper rod 17 will cause debris on the surface of rotating plate one 12 to slide onto the surface of rotating plate two 13. The debris on the surface of rotating plate two 13 will continue to slide downwards and be discharged from the discharge chute three to the outside of the testing cabinet 1. After each test, ultraviolet irradiation will cause the sample surface to pulverize and degrade, producing debris. Through rotating plates one 12 and two 13, the surface debris can be discharged to the outside of the testing cabinet 1 while the old sample is being removed, ensuring that each test is conducted in a standard, clean initial environment, resulting in strong data comparability.

[0047] Example 2

[0048] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, an artificial turf weather resistance testing device further includes a sealing device and a discharge device.

[0049] The sealing device includes a second connecting rod 21, a sliding block 22, a positioning rod 25, a sliding rod 26, a third connecting rod 27, a fourth connecting rod 28, and a sliding cover 29. The sliding block 22 is slidably installed on the inner wall of the testing cabinet 1. One end of the second connecting rod 21 is rotatably connected to the sliding block 22, and the other end of the second connecting rod 21 is rotatably connected to the placement platform 6. The positioning rod 25 is fixedly installed on the inner wall of the testing cabinet 1. The sliding rod 26 is slidably installed on the top of the sliding frame 23. One end of the third connecting rod 27 is rotatably connected to the positioning rod 25, and the other end of the third connecting rod 27 is rotatably connected to the sliding rod 26. The sliding cover 29 is slidably installed on the inner wall of the sliding frame 23. One end of the fourth connecting rod 28 is rotatably connected to the sliding rod 26, and the other end of the fourth connecting rod 28 is rotatably connected to the sliding cover 29.

[0050] The sealing device also includes a baffle plate 291 and a connecting rod 292. The baffle plate 291 is slidably installed on the inner wall of the sliding frame 23. One end of the connecting rod 292 is rotatably connected to the sliding cover 29, and the other end of the connecting rod 292 is rotatably connected to the baffle plate 291.

[0051] The sliding block 22 is inclined on the side near the sliding frame 23. The inclined surface of the sliding block 22 is to facilitate pushing the sliding frame 23 to reset. An elastic element 3 is provided between the sliding frame 23 and the detection cabinet 1. The elastic element 3 is provided to facilitate moving the sliding frame 23 downward. The sliding cover 29 is divided into a first cover plate and a second cover plate. The first cover plate and the second cover plate have slots inside. The shape of the slots matches the ultraviolet lamp 24.

[0052] The emission device includes a fixed rod 31, a baffle 32, a rotating rod 33, a connecting rod 34, and a long rod 35. The fixed rod 31 is slidably installed on the inner wall of the testing cabinet 1 and is fixedly connected to the sliding frame 23. An exhaust hole is provided on the inner wall of the testing cabinet 1. The baffle 32 is rotatably installed on the inner wall of the testing cabinet 1 near the exhaust hole. The rotating rod 33 is fixedly installed on the circumferential surface of the rotating shaft of the baffle 32. One end of the connecting rod 34 is rotatably connected to the fixed rod 31, and the other end of the connecting rod 34 is rotatably connected to the rotating rod 33. The rotating rod 33 is a telescopic rod. The long rod 35 is rotatably installed on the movable end of the rotating rod 33.

[0053] The discharge device also includes a gear 36, a rotating connecting rod 37, and a cleaning rod 38. The gear 36 rotates through the inner wall of the test cabinet 1, the rotating connecting rod 37 is fixedly installed on the circumferential surface of the shaft of the gear 36, and the cleaning rod 38 is slidably installed on the outer wall of the test cabinet 1 near the exhaust port.

[0054] The rotating connecting rod 37 is a telescopic rod 2. The movable end of the rotating connecting rod 37 is rotatably connected to the cleaning rod 38. The fixed rod 2 31 is fixedly installed with a ruler tooth on the side near the gear 36. The ruler tooth matches the gear 36.

[0055] In this embodiment, when the placement platform 6 moves inward, it will drive the second connecting rod 21 to move. The movement of the second connecting rod 21 will push the sliding block 22 to move away from the placement platform 6. The movement of the sliding block 22 away from the placement platform 6 will cause the sliding frame 23 to slowly slide along the inclined surface of the sliding block 22 towards the placement platform 6. The movement of the sliding frame 23 will drive the ultraviolet lamp 24 to move closer to the lawn. The downward movement of the sliding frame 23 will drive the sliding rod 26 to move away from the positioning rod 25. Then the positioning rod 25 will... By pulling the sliding rod 26 towards the positioning rod 25 via the connecting rod 3 27, the sliding rod 26 will pull the connecting rod 4 28 to move. The movement of the connecting rod 4 28 will push the sliding cover 29 away from the ultraviolet lamp 24, thus removing the obstruction of the ultraviolet lamp 24 and allowing the ultraviolet lamp 24 to irradiate the lawn with ultraviolet light. By moving the placement platform 6 inward, the ultraviolet lamp 24 can be automatically triggered to precisely descend to the working position, and the sliding cover 29 will open simultaneously, simplifying the operation process. The descent and exposure are strictly dependent on the placement platform 6 being fully inside the sealed testing cabinet 1. The ultraviolet lamp 24 will not descend or operate as long as the placement platform 6 is not inside the testing cabinet 1, effectively preventing personnel from being exposed to ultraviolet radiation when loading samples. When the testing is finished and the placement platform 6 is moved out to remove the sample, the mechanism will reverse, causing the ultraviolet lamp 24 to rise and the sliding cover 29 to automatically close, thus shielding the hazardous light source before personnel come into contact with the sample. When the sliding cover 29 moves, it pushes the connecting rod 5 292 to move, which in turn pushes the shielding plate 291 downwards. The downward movement of the shielding plate 291 enhances the shielding effect by blocking the area around the ultraviolet lamp 24. The shielding plate 291 strengthens the airtightness of the testing cabinet 1, preventing external ambient light from entering through gaps during testing and contaminating the pure ultraviolet or simulated solar spectrum testing environment. It allows ultraviolet light to be more concentrated and uniformly irradiated downwards onto the sample surface, reducing disordered reflection and scattering of light within the lamp holder cavity, resulting in more uniform light intensity and more accurate spectrum received by the sample surface.

[0056] When the sliding frame 23 moves downward, it pulls the fixed rod 31 downward. The downward movement of the fixed rod 31 pulls the rotating rod 33 to rotate via the connecting rod 34. The rotation of the rotating rod 33 causes the baffle 32 to rotate away from the exhaust port, thus releasing the baffle 32 from obstructing the exhaust port. When the fixed rod 31 moves downward, it causes the gear teeth to move, which in turn causes the gear 36 to rotate. The rotation of the gear 36 causes the rotating connecting rod 37 to rotate, which in turn causes the cleaning rod 38 to slide. The sliding of the cleaning rod 38 scrapes and cleans the outside of the exhaust port, wiping away excess dust. Through the linkage mechanism, the exhaust baffle 32 is automatically opened, which allows the inspection... During the testing process, volatile organic compounds, trace amounts of ozone, heat, and water vapor generated by material decomposition can be discharged in real time. Continuous exhaust prevents harmful gases and overheated air from accumulating in the sealed testing cabinet 1, avoiding unknown chemical interference with the test and avoiding safety risks caused by excessive pressure or temperature. In the same process of opening the baffle 32, the linear motion is converted into rotation through the teeth of the ruler and gear 36, and then the cleaning rod 38 is driven to scrape and clean the outer surface of the exhaust port to ensure smooth ventilation. The unobstructed exhaust port ensures that the exhaust rate and the air exchange rate in the cabinet are basically consistent for each test. This is a key prerequisite for maintaining controllable and repeatable environmental parameters such as temperature, humidity, and gas concentration.

[0057] Example 3

[0058] Based on Examples 1 and 2, this example provides a method for using an artificial turf weather resistance testing device, including the following steps:

[0059] Step 1: When cabinet door 2 is closed, it will drive pull rod 3 to move. The movement of pull rod 3 will push connecting rod 4 to move. The movement of connecting rod 4 will pull fixed rod 5 to move. The movement of fixed rod 5 will cause the placement platform 6 containing grass to slide into the testing cabinet 1.

[0060] Step 2: When the lawn is inside the testing cabinet 1, the rotating block 9 will rotate. When the rotating block 9 rotates, it will press the movable plate 10 to move downward. The downward movement of the movable plate 10 will cause the lawn to slide into the placement platform 6. When the pressure block 11 applies a certain pressure to the lawn, the lawn will not warp or shift due to thermal expansion, airflow or vibration during the test.
