[0044] Figure 1The right side structural diagram of a UV test device according to an embodiment of the present disclosure is shown. Figure 1 The ultraviolet testing equipment includes a housing 1, a control module, a rotating assembly 2, a plurality of ultraviolet generating devices 3 and a plurality of samples to be tested 4. A plurality of inclined plates 5 are arranged inside the housing 1, and the plurality of inclined plates 5 separate the interior of the housing 1 into a plurality of test areas, and the area between two adjacent inclined plates 5 is a test area. A corresponding ultraviolet generating device 3 and a sample to be tested 4 are arranged inside each test area, and the ultraviolet generating device 3 is used to emit ultraviolet light to the surface of the sample to be tested 4.

[0045] The present disclosure does not limit the ultraviolet generating device 3. In one embodiment, the ultraviolet generating device 3 is an ultraviolet lamp. The ultraviolet testing equipment includes three types of ultraviolet lamps: UVA-340, UVA-351 and UVB-313. The UVA-340 lamp is mainly used to simulate short-wave ultraviolet (UV-A) radiation, and its wavelength range is 320-340 nanometers. The UVA-351 lamp is used to simulate medium-wave ultraviolet (UV-A) radiation, and its wavelength range is 350-370 nanometers. The UVB-313 lamp is used to simulate long-wave ultraviolet (UV-B) radiation, and its wavelength range is 280-315 nanometers. In one embodiment, the ultraviolet testing equipment includes three test areas, and each test area is provided with a mounting interface on the left and right sides. The two ends of the ultraviolet lamp are respectively fixed on the mounting interfaces on the left and right sides, and 4 ultraviolet lamps are installed at the front and rear ends of the test area. The present disclosure does not limit the sample 4 to be tested. The sample 4 to be tested can be a plastic part, a sprayed part, a cloth, etc.

[0046] like Figure 1 The first end of the rotating component 2 is fixed to the top of the shell 1, and the second end of the rotating component 2 is located inside the bottom test area among the multiple test areas. Multiple sample fixing racks 6 are fixedly installed on the rotating component 2 to drive the multiple sample fixing racks 6 to rotate; each sample fixing rack 6 is arranged inside the corresponding test area, located at the center of the test area, and the sample fixing rack 6 is used to fix the sample 4 to be tested.

[0047] By arranging an independent UV generator 3 and a sample to be tested 4 in each test area, multiple samples can be tested simultaneously under different UV conditions, which greatly improves the test efficiency; the rotating component 2 uniformly drives multiple sample fixing frames 6 to rotate, ensuring that the surface of the sample to be tested 4 is evenly irradiated with ultraviolet light, while simplifying the design of the equipment and reducing complex mechanical structures; by arranging multiple inclined plates 5 inside the shell 1 to separate the test areas, the vertical space is used for multi-level test design, which saves floor space and makes the overall structure of the equipment compact.

[0048] The present disclosure does not limit the rotating assembly 2. In one embodiment, the rotating assembly 2 includes a driving mechanism 21 and a screw 22 driven by the driving mechanism to rotate around its own axis. The driving mechanism 21 is fixed at the top of the housing 1. The screw 22 passes through the top test area and at least one middle test area, so that the end of the screw 22 is located inside the bottom test area. A plurality of sample holders 6 are fixedly mounted on the screw 22. After the driving mechanism 21 rotates 30°, it pauses for a preset time to ensure that the sample 4 to be tested is exposed to ultraviolet light for a sufficient time at the current angle to perform a sufficient aging test. The screw 22 is driven to rotate by a driving mechanism 21, which simplifies the overall structural design of the device, reduces the number of moving parts that need to be maintained, and thus reduces the complexity and maintenance cost of the device. In one embodiment, the plurality of inclined plates 5 include a top inclined plate and at least one middle inclined plate. The screw 22 passes through the through holes on the top inclined plate and at least one middle inclined plate, so that the end of the screw 22 is located inside the bottom test area. The through holes are equipped with bearings to support the rotation of the screw 22. By assembling the bearing in the through hole, the rotation of the screw rod 22 can be effectively supported, friction and wear can be reduced, and the sample fixing frame 6 can be ensured to remain stable during the rotation process.

Figure 2 The outer wall of the sample holder 6 is provided with a plurality of grooves in sequence, the grooves are adapted to the sample 4 to be tested, and are used to place the sample 4 to be tested. The edges of the grooves are provided with a plurality of limiters 61, and the limiters 61 are used to limit the position of the sample 4 to be tested. The present disclosure does not limit the shape of the sample holder 6. In one embodiment, the sample holder 6 is a hexagonal prism, and each side of the hexagonal prism is provided with a groove for placing the sample 4 to be tested. The present disclosure does not limit the limiter 61. In one embodiment, the limiter 61 is a magnetic ring buckle, and the buckle mechanism is used to secure the sample 4 to be tested in the groove to prevent the sample 4 to be tested from moving during the test process.

[0050] The outer wall of the sample fixing frame 6 is provided with a plurality of grooves adapted to the sample to be tested 4, which can firmly place the sample to be tested 4 in a fixed position. The limiting piece 61 at the edge of the groove further limits the position of the sample to be tested 4 to prevent the sample to be tested 4 from falling during rotation; at the same time, the operation process is simplified, which facilitates the rapid replacement and adjustment of the sample to be tested 4 and improves work efficiency.

The first end of the first water pipe 7 is connected to the liquid outlet end of the water tank through a pumping device, and the pumping device is used to transport the water in the water tank to the first water pipe 7. The first water pipe 7 passes through the bottom test area and at least one middle test area, so that the second end of the first water pipe 7 is located inside the top test area. The pipe section of the first water pipe 7 in each test area is provided with an opening, and the opening is connected to a spray head 71, and the spray head 71 is used to spray water onto the surface of the sample 4 to be tested. A water purification device and a water tank are provided at the bottom of the shell 1. The water is filtered by the water purification device and then transported to the water tank, thereby realizing the automatic supply of test water. The first water pipe 7 is provided with a spray head 71 in each test area, which can test multiple samples under wet conditions at the same time, simplifying the design and operation process of the equipment and improving the test efficiency.

[0052] The present disclosure does not limit the spray head 71, which can be a stainless steel micro-spray nozzle, made of 304 or 316 stainless steel, with high temperature resistance and corrosion resistance. The nozzle adopts full cone or fan spray, the spray angle is between 30° and 120°, and is equipped with a valve with adjustable flow to control the spray intensity. The present disclosure does not limit the water purification device. In one embodiment, the water purification device includes a CPP composite filter element, a booster pump and a NF / RO filter element. Tap water enters the water purification device through a water inlet pipe. The tap water first passes through the CPP composite filter element in the water purification device for primary filtration to remove larger particulate impurities and some organic matter; the water after primary filtration is pressurized by a booster pump to ensure sufficient pressure to enter the subsequent fine filtration stage; the pressurized water enters the NF (nanofiltration) or RO (reverse osmosis) filter element for deep filtration to remove fine particles, heavy metals, bacteria and other dissolved substances, produce pure water and transport it to the water tank.

[0053] In one embodiment, Figure 5 FIG. 2 is a schematic diagram showing the internal structure of a water tank according to an embodiment of the present disclosure. Figure 5The device also includes a capacitive sensor 81 and a float 82. The side wall inside the water tank is provided with a guide groove 83 and a capacitive sensor 81. The float 82 is located in the guide groove 83. The guide groove 83 is used to limit the moving path of the float 82 inside the water tank so that the float 82 moves along the guide groove 83. The side of the guide groove 83 is not closed, and a vertical opening connecting the top and the bottom is provided on the side. The disclosure does not limit the width of the vertical opening. The float 82 cannot be moved out of the vertical opening, and the width is large enough so that the water outside the guide groove 83 can flow into the inside of the guide groove 83, so that the water surface height inside and outside the guide groove 83 is consistent. The disclosure does not limit the material of the float 82. The float 82 can float on the water surface, and the position change of the float 82 can affect the detection value of the capacitive sensor 81. The material of the float 82 can be a material with good buoyancy and corrosion resistance, such as polyethylene (PE), polypropylene (PP) or polyvinyl chloride (PVC). The capacitive sensor 81 is located directly above the guide groove 83 and is used to detect the float 82. When the detected induction value is greater than the preset threshold, a stop signal is sent to the control module. The stop signal is used to instruct the water purification device to stop working. The capacitive sensor 81 and the float 82 are used together to accurately detect the water level in the water tank. When the float 82 rises to the preset water level, the capacitive sensor 81 detects that the induction value is greater than the preset threshold, and automatically sends a stop signal to the control module, instructing the water purification device to stop working, thereby realizing automatic control of the water level. Through the capacitive sensor 81 and the float 82, the water level of the water tank can be detected and controlled in time to prevent the water overflow in the water tank caused by the water level being too high, thereby ensuring the safety of the equipment and the environment.

[0054] Figure 4 FIG. 2 shows a schematic diagram of the front structure of a UV test device according to an embodiment of the present disclosure. The plurality of inclined plates 5 include a top inclined plate, at least one middle inclined plate and a bottom inclined plate. Figure 4 The device also includes a second water pipe 9, which passes through the bottom inclined plate and at least one middle inclined plate. A drainage hole is provided at the low position of the inclined plate 5, and the drainage hole is connected to the second water pipe 9 through a branch pipe. The branch pipe is used to transport the water inside the test area to the second water pipe 9. The present disclosure does not limit the inclined plate 5. In one embodiment, the inclined plate 5 is tilted to the right, so that the height of the left side of the inclined plate 5 is greater than the height of the right side, and the tilt angle can make the water flow to the low position. The drainage port of the second water pipe 9 is connected to the liquid inlet of the water purification device, which is used to transport the water in the second water pipe 9 to the water purification device for filtration. The second water pipe 9 realizes the automatic discharge and recovery of water in the test area by connecting the drainage holes on multiple inclined plates 5; the discharged water enters the second water pipe 9 through the branch pipe, and is then transported to the water purification device through the drainage port of the second water pipe 9 for filtration, forming an efficient water circulation system, reducing the waste of water resources, and improving the environmental protection performance of the equipment.

[0055] In one embodiment, the device further includes a display screen and a plurality of photographing devices. The display screen is disposed on the outer wall of the shell 1 for displaying images of a plurality of samples 4 to be tested. Each photographing device is installed on the inner wall of the corresponding test area for photographing the image of the sample 4 to be tested and transmitting it to the display screen. The present disclosure does not limit the photographing device. The photographing device may be a high temperature resistant and waterproof camera, which can rotate and retract to automatically focus on the sample 4 to be tested. The combined design of the display screen and the photographing device enables the operator to monitor the status of the sample 4 to be tested in each test area in real time, so as to observe the test process and results at any time. The remote viewing of the sample 4 to be tested through the display screen reduces the need for the operator to frequently switch the equipment on and off for inspection, reduces the frequency of human intervention, and thus improves the automation level and test efficiency of the equipment.
