Description

Technical Field

[0001] This utility model relates to the field of water-repellent experimental technology for light-transmitting panels, specifically, to a water-repellent experimental device for light-transmitting panels. Background Technology

[0002] As a core lighting component in industrial plants, greenhouses, public buildings, and other settings, the hydrophobicity of the surface of a light-transmitting panel directly determines its service life and performance stability. In rainy or snowy weather, if the hydrophobicity is poor, moisture can easily adhere to and penetrate into the interior of the panel, leading not only to a decrease in light transmittance but also damage to the panel structure due to freeze-thaw cycles, shortening its service life by 3-5 years. Long-term damp environments are also more prone to mold growth, further deteriorating the lighting effect and building hygiene conditions. Therefore, it is necessary to conduct hydrophobicity tests on the panel.

[0003] Existing experimental devices are not convenient for water recycling and reuse, resulting in significant water waste and increased experimental costs. Furthermore, some existing devices lack a limiting structure for the light-collecting plate, which is often placed directly inside the experimental tank, making positional adjustment difficult and reducing experimental flexibility. The light-collecting plate may also shift during the experiment, affecting its stability. Therefore, this invention provides a hydrophobic experimental device for light-collecting plates to solve the above problems. Utility Model Content

[0026] like Figures 1 to 6 As shown, this utility model provides a hydrophobic experimental device for a light-transmitting panel, including: an experimental structure 1, which includes a water tank 11, an experimental tank 14, a first connecting pipe 15, a bidirectional lead screw 17, a nozzle 111 and a water pump 112. The water pump 112 is installed on the upper surface of the water tank 11. The experimental structure 1 is used for a hydrophobic experiment on the light-transmitting panel. Filter structure 2 includes a filter box 21, a limiting post 23 and a conical filter cylinder 24. The interior of the filter box 21 is connected to the interior of the experimental tank 14 through a first connecting pipe 15. Filter structure 2 is used to filter water sources. The fixing structure 3 has two sets, and the positions of the two sets of fixing structures 3 are symmetrical to each other. Each set of fixing structures 3 includes a connecting frame 31, a limiting rod 32, a T-shaped slide rail 33, a second slide block 34, and a fixing pad 38. The lower ends of the two sets of connecting frames 31 are respectively threaded to the two ends of the outer surface of the bidirectional lead screw 17. The two sets of fixing structures 3 are used to clamp and fix the light-collecting panel.

[0027] Among them, a drain pipe 12 is connected to the inside of one side surface of the water tank 11, a support frame 13 is fixedly connected to the upper surface of the water tank 11, the upper surface of the support frame 13 is fixedly connected to the lower surface of the experimental tank 14, and the first connecting pipe 15 is connected to the inside of the lower surface of the experimental tank 14.

[0028] The water inside the water tank 11 can be drained and replaced through the drain pipe 12. The support frame 13 can support the experimental tank 14, improving the stability of the experimental tank 14 during use. The experimental tank 14 can support the light-transmitting panel to be tested. The water during the experiment will be collected inside the experimental tank 14 and then flow into the first connecting pipe 15 by its own gravity.

[0029] Among them, a bearing seat 16 is fixedly connected to the middle position of the lower surface of the experimental tank 14, and a double-acting screw 17 is connected to the inside of the bearing seat 16. A throttle is provided at one end of the double-acting screw 17.

[0030] The throttle design allows operators to rotate the bidirectional lead screw 17 more easily, while the bearing 16 improves the stability of the bidirectional lead screw 17 during rotation, preventing it from wobbling or slipping.

[0031] The water tank 11 has an adjusting column 18 fixedly connected to its upper surface. A first slide block 19 is slidably sleeved on the outer surface of the adjusting column 18. A connecting rail 110 is fixedly connected to one side surface of the first slide block 19. The nozzle 111 is slidably sleeved on the outer surface of the connecting rail 110. Locking bolts are provided inside both the first slide block 19 and the nozzle 111.

[0032] Pulling the first slide block 19 allows it to slide longitudinally parallel on the outer surface of the adjusting column 18. When the first slide block 19 moves, it drives the connecting rail 110 and the nozzle 111 to move synchronously. At this time, the height of the nozzle 111 can be adjusted. The locking bolt inside the first slide block 19 can fix the position of the first slide block 19 on the outer surface of the adjusting column 18, thereby fixing the height of the connecting rail 110 and the nozzle 111. Pulling the nozzle 111 allows it to slide laterally parallel on the outer surface of the connecting rail 110. At this time, the position of the nozzle 111 can be adjusted according to the specific situation during the experiment. The locking bolt inside the nozzle 111 can fix the position of the nozzle 111 on the outer surface of the connecting rail 110.

[0033] The water pump 112's inlet pipe is connected to the inside of the water tank 11, and the water pump 112's outlet pipe is connected to the inside of the nozzle 111.

[0034] Water pump 112 draws water from inside water tank 11 and delivers it to nozzle 111. Finally, the water is sprayed onto the upper surface of the light-transmitting panel to conduct a hydrophobicity test. Water pump 112 is a miniature centrifugal pump with a head of 0.5-2m and a flow rate of 1-5L / min, ensuring that the spraying pressure of nozzle 111 is stable at 0.1-0.3MPa. Nozzle 111 uses a fan-shaped mist nozzle with 3-5 nozzles, each with a diameter of 0.5-1mm. The spraying pressure range is 0.1-0.3MPa, suitable for simulating a moderate rain environment in the hydrophobicity test.

[0035] The filter box 21 is fixedly connected to a limiting ring 22, and a limiting post 23 is fixedly connected to the upper surface of the limiting ring 22. The lower surface of the upper end of the conical filter cylinder 24 is attached to the upper surface of the limiting ring 22. Limiting holes 25 are opened inside both sides of the upper end of the conical filter cylinder 24, and the limiting post 23 is inserted into the inside of the limiting hole 25.

[0036] The water generated during the experiment can be transported to the interior of the filter box 21 through the first connecting pipe 15. The conical filter cylinder 24 can filter the impurities inside the water source. The conical filter cylinder 24 is made of PP plastic, with a taper of 1:5-1:8 and a filtration accuracy of 50-100μm. It can filter dust on the surface of the light-transmitting panel and suspended impurities in the water generated during the experiment. The position of the conical filter cylinder 24 can be fixed by the setting of the limiting ring 22 and the limiting post 23, which can prevent the conical filter cylinder 24 from rotating or shaking during use.

[0037] The filter box 21 is connected to a second connecting pipe 26 at its lower end, and the end of the second connecting pipe 26 away from the filter box 21 is connected to the interior of the water tank 11. The filter box 21 is fitted with a sealing cover 27 at its upper end.

[0038] The filtered water can be fed into the water tank 11 through the second connecting pipe 26, thus completing the water circulation. The sealing cover 27 can seal the inside of the filter box 21 to prevent external dust and impurities from entering the filter box 21. The lower surface of the sealing cover 27 is provided with a rubber sealing ring, which fits against the upper surface of the filter box 21 to achieve a seal and prevent external dust from entering. Pulling the sealing cover 27 can remove it from the upper surface of the filter box 21. At this time, the conical filter cylinder 24 can be pulled out from the inside of the filter box 21 for cleaning.

[0039] Among them, the opposite ends of the two sets of limiting rods 32 are fixedly connected to the outer surfaces of the two side walls of the experimental tank 14, and the two sets of limiting rods 32 are slidably inserted into the interiors of the two sets of connecting frames 31.

[0040] By rotating the bidirectional lead screw 17, the two sets of connecting frames 31 can be driven to move closer or further apart synchronously, thereby adjusting the overall spacing of the two sets of fixed structures 3, so that the positions of the two sets of fixing pads 38 can be adjusted for light-transmitting panels of different widths.

[0041] The T-shaped slide rail 33 is fixedly connected to the upper end of the connecting frame 31, and the second slide block 34 is slidably sleeved on the outer surface of the T-shaped slide rail 33. The upper surface of the second slide block 34 is internally threaded with a locking bolt 35, and the lower end of the locking bolt 35 is attached to the upper surface of the T-shaped slide rail 33.

[0042] By pulling the second slide block 34, it can slide on the outer surface of the T-shaped slide rail 33, and can drive the connecting plate 36, the fixing screw 37 and the fixing pad 38 to move synchronously, so that the two sets of fixing pads 38 can fix the light-collecting plate in different positions inside the experimental tank 14.

[0043] Among them, a connecting plate 36 is fixedly connected to the surface of the opposite side of the two sets of T-shaped slide rails 33. A fixing screw 37 is connected to the internal thread of the connecting plate 36, and a fixing pad 38 is fixedly connected to the lower end of the fixing screw 37.

[0044] Rotating the fixing screw 37 can drive the fixing pad 38 to move longitudinally inside the experimental tank 14. When the lower surface of the fixing pad 38 is in contact with the light-transmitting plate, the position of the light-transmitting plate can be fixed. This design allows two sets of fixing pads 38 to fix light-transmitting plates of different thicknesses. The lower surface of the fixing pad 38 is provided with a rubber pad, which can increase the friction with the upper surface of the light-transmitting plate, prevent the light-transmitting plate from sliding during the experiment, and prevent damage to the upper surface of the light-transmitting plate during fixing.

[0045] The working principle and usage process of this utility model are as follows: First, place the light-collecting panel to be tested inside the experimental tank 14. Rotate the bidirectional lead screw 17 to drive the two sets of connecting frames 31 to move closer or further away from the two sets of limiting rods 32 simultaneously to adjust the distance between the two sets of fixing structures 3. Then, pull the two sets of second slide blocks 34 to slide on the two sets of T-shaped slide rails 33 to the position suitable for fixing the light-collecting panel. Next, fix the position of the two sets of second slide blocks 34 with the two sets of locking bolts 35. Then, rotate the two sets of fixing lead screws 37 to make the lower surface of the two sets of fixing pads 38 fit against the upper surface of the light-collecting panel to complete the clamping and fixing of the light-collecting panel. Then, slide the first slide block 19 to adjust the height on the adjusting column 18, and slide the nozzle 111 to adjust the height on the connecting rail 110. The first slide 19 and the nozzle 111 are fixed in a horizontal position by corresponding locking bolts; then the water pump 112 is started to draw water from the water tank 11 and deliver it to the nozzle 111, from which the nozzle 111 sprays water onto the light-transmitting panel to conduct a water-repellent experiment; during the experiment, the water in the experimental tank 14 flows into the filter box 21 through the first connecting pipe 15, and after being filtered by the conical filter cylinder 24, it flows back to the water tank 11 through the second connecting pipe 26 to achieve water circulation; if the water source needs to be replaced, the water in the water tank 11 can be discharged through the drain pipe 12; if the conical filter cylinder 24 needs to be cleaned, the sealing cover 27 at the top of the filter box 21 can be opened, the conical filter cylinder 24 can be taken out for cleaning, and then reinserted into the limiting post 23 to complete the reset.

[0046] However, as is well known to those skilled in the art, the working principle and wiring method of the water pump 112 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Furthermore, all threaded parts and movable parts in this application need to be cleaned and maintained regularly (including but not limited to dust removal, lubrication, etc.) to ensure their normal operation.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
