Description

Technical Field

[0001] The invention relates to the technical field of functional films, and in particular to a method for preventing rain and reflection of windows of transformer substation equipment. Background Art

[0002] Substation windows play an important role in substations, and are mainly used to observe the operating status of equipment. Through the windows, staff can visually observe the operating conditions of various electrical equipment in the substation, such as transformers, switchgear, mutual inductors, etc., and promptly discover whether the equipment has low pressure, oil leakage, abnormal energy storage, etc., so as to take appropriate measures to deal with it and ensure the safe and stable operation of the equipment. For some key equipment, the windows can provide a clearer observation angle, help staff accurately judge the operating status of the equipment, and improve the accuracy and timeliness of fault diagnosis.

[0003] At present, cameras are used to perform sequential control operations and inspections on power grid-controlled substations. However, the windows are blocked by raindrops on rainy days, and reflections occur due to high sunlight illumination, which will affect the camera's recognition. For windows that need to be observed, they should have high transparency and clarity so that people can clearly see the objects or information behind the windows. However, because ordinary glass reflects light under light, the indications and meters in the windows cannot be seen clearly. In addition, the sequential control operation images and meters are often unclear due to rain on rainy days, resulting in the inability to distinguish the switch and knife switch opening and closing indications in the collected images, and the algorithm cannot quickly identify them, affecting the efficiency of sequential control operations, and the safety of sequential control on rainy days is difficult to guarantee. At the same time, strong sunlight causes the windows to reflect, resulting in the video not being able to see the window indications and meter counts clearly, resulting in inability to identify.

[0004] Therefore, it is necessary to design the windows of substation equipment to be rainproof and anti-reflective. The inventors affixed anti-reflective and hydrophobic films on the windows of substation equipment in order to reduce the adhesion of rainwater and the reflection of windows. However, the windows of different types of substation equipment have different shapes, such as round, square, etc., and have frames, which makes it difficult to apply the film, and bubbles are likely to appear when applying the film, affecting the viewing effect. Summary of the invention

[0005] Based on this, it is necessary to provide a rainproof and anti-reflective method for the windows of substation equipment to solve the problem that the window film of substation equipment is difficult to operate and bubbles are easily generated when the film is applied.

[0010] The lifting mechanism of the film sticking device is operated in batches to drive the corresponding suction cups down in turn, so that multiple areas of the anti-reflective hydrophobic film are attached to the window in turn. During the process, a scraper is used to scrape the attached parts of the anti-reflective hydrophobic film to remove bubbles.

[0017] In some embodiments, the anti-reflective hydrophobic film further includes a PET protective layer, and the PET protective layer is disposed between the functional layer and the fluorosilicone resin film layer.

[0037] A method for preventing rain and reflection of windows of substation equipment according to an embodiment of the present invention comprises the following steps:

[0038] Step S1, providing three or more film sticking devices. As shown in FIG1 , the film sticking device includes a mounting seat 11, a lifting mechanism 12, a suction cup 13, and a glue sticking base 14. The lifting mechanism 12 is movably disposed on the mounting seat 11, the lifting mechanism 12 is connected to the suction cup 13 to drive the suction cup 13 to rise or fall, and the glue sticking base 14 is connected to the bottom of the mounting seat 11.

[0039] Step S2, more than three film sticking devices are distributed around the window, and the adhesive adhesive base 14 is adhered to the frame of the window.

[0040] Step S3, taking the anti-reflective hydrophobic film and adsorbing it on the suction cup 13 of each film sticking device.

[0041] Step S4, operating the lifting mechanism 12 of the film sticking device in batches, driving the corresponding suction cups 13 to descend in turn, so that multiple areas of the anti-reflective hydrophobic film are attached to the window in turn, and using a scraper to flatten the parts where the anti-reflective hydrophobic film is attached to remove bubbles.

[0042] The above-mentioned rainproof and anti-reflective method for the window of the substation equipment is to use a film sticking device, and more than three film sticking devices are distributed around the window. The film sticking device includes a clay sticking base 14, and the clay sticking base 14 can be adhered to the frame of the window, and the clay sticking base 14 is deformable and can adapt to the non-flat window frame. The setting of more than three film sticking devices can adapt to windows of different shapes. The suction cups 13 of multiple film sticking devices can cooperate to absorb the anti-reflective hydrophobic film. By operating the lifting mechanism 12 of the film sticking device in batches, the corresponding suction cups 13 are driven to descend in turn, so that multiple areas of the anti-reflective hydrophobic film are attached to the window in turn, reducing the situation of foaming when the whole film is pasted at the same time. And a scraper is used in the process to scrape the part where the anti-reflective hydrophobic film is attached, which can easily drive out bubbles. The above-mentioned rainproof and anti-reflective method can standardize the film sticking operation, which is simple and easy to operate, and can also avoid the situation of bubbles when the windows of various substation equipment are filmed.

[0043] In some of the examples, there are more than four film-sticking devices, such as 4 to 10.

[0044] In some of these examples, step S3 includes:

[0045] Align the anti-reflective hydrophobic film and place it on the window of the substation equipment, operate the lifting mechanism 12 of the film sticking device to drive the suction cup 13 to descend, and absorb the anti-reflective hydrophobic film. Then operate the lifting mechanism 12 of the film sticking device to drive the suction cup 13 to rise, suck up the anti-reflective hydrophobic film, and remove the release film of the anti-reflective hydrophobic film.

[0046] The transparency and clarity of the window are its important performance indicators. For windows that need to be observed, they should have high transparency and clarity so that people can clearly see the objects or information behind the window. Therefore, it is usually chosen to protect them by sticking anti-reflective film. At present, the camera method is used to perform equipment sequential control operations on power grid controlled substations. However, the sequential control operation images are often unclear due to rain on rainy days, resulting in the inability to distinguish the switch and knife switch opening and closing indications in the collected images, and the algorithm cannot quickly identify them, which affects the efficiency of sequential control operations, and the safety of sequential control on rainy days is difficult to guarantee.

[0047] The present invention further designs the structure of the anti-reflective hydrophobic film.

[0048] As shown in Figures 2 and 3, the anti-reflective hydrophobic film 100 includes a substrate layer 110 and a fluorosilicone resin film layer 120, and the fluorosilicone resin film layer 120 is disposed on the substrate layer 110. The side of the fluorosilicone resin film layer 120 away from the substrate layer 110 is provided with nano spherical protrusions 130.

[0049] The above-mentioned anti-reflective hydrophobic film 100 is provided with a fluorosilicone resin film layer 120 on the substrate layer 110. The fluorosilicone resin film layer 120 is a transparent film layer and has a good hydrophobic effect. In addition, nano-spherical protrusions 130 are distributed on the side of the fluorosilicone resin film layer 120 away from the substrate layer 110. The "lotus leaf effect" is used to better reduce the adhesion of water droplets on the surface of the fluorosilicone resin film layer 120, thereby ensuring visibility when it rains and avoiding unclear images of sequential control operations when collecting on rainy days.

[0050] In some examples, the material of the nano-spherical protrusions 130 is nano-silicon dioxide.

[0051] In some examples, the particle size of the nano-spherical protrusions 130 is 1 nm to 1.5 nm.

[0052] In some of the examples, the nanoparticles are distributed on the fluorosilicone resin film layer 120 by sprinkling the nanoparticles on the fluorosilicone resin film layer 120 before the fluorosilicone resin film layer 120 is cured, and the nano-spherical protrusions 130 attached to the fluorosilicone resin film layer 120 are formed after the fluorosilicone resin film layer 120 is cured.

[0053] In some examples, the material of the substrate layer 110 is PET.

[0054] In some examples, the thickness of the substrate layer 110 is 100 μm-125 μm.

[0055] As shown in FIG. 2 , in some examples, the anti-reflective hydrophobic film 100 further includes a functional layer 140 , which is disposed between the substrate layer 110 and the fluorosilicone resin film layer 120 , and the functional layer 140 includes at least one of a waterproof and oil-proof layer, an anti-reflective layer, and a hardened coating layer.

[0056] In some of these examples, the material of the water and oil repellent layer is a fluorosilicone polymer.

[0057] During the production process, thermal evaporation or spraying technology is used, with fluorosilicone polymers as the coating material to form an AF film with a waterproof and oil-proof layer.

[0058] In some of the examples, the thickness of the waterproof and oil-proof layer is 1 nm to 1 μm. Further, in some of the examples, the thickness of the waterproof and oil-proof layer is 50 nm to 500 nm. In some specific examples, the thickness of the waterproof and oil-proof layer is, for example, 1 nm, 10 nm, 50 nm, 100 nm, 300 nm, 500 nm, 800 nm, 1 μm, etc.

[0059] In some examples, the anti-reflection layer includes a high refractive index layer and a low refractive index layer stacked together, the refractive index of the high refractive index layer is greater than the refractive index of the low refractive index layer, and the material of the high refractive index layer is selected from Nb 2 O 5、TiO 2 、 2 O 5 、H4、Si 3 N x At least one of the following, wherein the range of x is 2 to 5, and the material of the low refractive index layer is selected from SiO 2 、Al 2 O 3 MgF 2 At least one of .

[0060] During the production, magnetron sputtering or vacuum evaporation technology is used, and the AR functional layer 140 film is alternately stacked and plated, which can reduce the reflected light on the surface of the object to be attached, thereby increasing the amount of light transmitted and achieving the effect of increasing transmittance and reducing reflection.

[0061] In some examples, the thickness of the anti-reflection layer is 0.01 μm to 2 μm. Further, in some examples, the thickness of the anti-reflection layer is 0.1 μm to 1 μm. In some specific examples, the thickness of the anti-reflection layer is, for example, 0.01 μm, 0.05 μm, 0.1 μm, 0.5 μm, 1 μm, 1.5 μm, 2 μm, etc.

[0062] In some of these examples, the material of the hard coating layer is a ceramic coating.

[0063] The hardened coating layer is hardened by a mercury lamp during manufacture, and the hardened coating layer can effectively reduce the risk of scratches on the surface of the substrate layer 110 .

[0064] In some examples, the thickness of the hardened coating layer is 0.5 μm to 1 μm. Further, in some examples, the thickness of the hardened coating layer is 0.6 μm to 0.8 μm. In some specific examples, the thickness of the hardened coating layer is, for example, 0.5 μm, 0.6 μm, 0.7 μm, 0.8 μm, 0.9 μm, 1 μm, etc.

[0065] As shown in Fig. 2, in some examples, the anti-reflective hydrophobic film 100 further includes a PET protective layer 150. The PET protective layer 150 is disposed between the functional layer 140 and the fluorosilicone resin film layer 120. The PET protective layer 150 can protect the inner film layer from being damaged.

[0066] In some examples, the thickness of the PET protective layer 150 is 40 μm to 50 μm.

[0067] As shown in Fig. 2, in some examples, the anti-reflective hydrophobic film 100 further includes an adhesive layer 160. The adhesive layer 160 is disposed on a side of the substrate layer 110 away from the fluorosilicone resin film layer 120. The adhesive layer 160 is used to enable the anti-reflective hydrophobic film 100 to be attached to the window of the substation equipment as a whole.

[0068] In some examples, the material of the adhesive layer 160 includes polyurethane (PU).

[0069] As shown in FIG4 , in some examples, a plurality of venting grooves 162 opening at the edge of the adhesive layer are provided on the side of the adhesive layer away from the substrate layer. When a scraper is used to scrape the attachment area of ​​the anti-reflective hydrophobic film, the moving direction of the scraper is consistent with the extending direction of the venting grooves 162 in the attachment area. In the specific example shown in FIG4 , the plurality of venting grooves 162 are arranged in parallel.

[0070] In some examples, the width of the exhaust groove 162 is 1 μm to 1.8 μm, and the depth of the exhaust groove 162 is 1.5 μm to 2 μm.

[0071] As shown in Fig. 2, in some examples, the anti-reflective hydrophobic film 100 further includes a release layer 170. The release layer 170 is disposed on a side of the adhesive layer 160 away from the substrate layer 110. The release layer 170 is used to protect the adhesive layer 160, and the release layer 170 can be easily peeled off.

[0072] In some examples, the adhesive layer 160 further contains a leveling agent, such as a fluorine-containing leveling agent, which is beneficial to the leveling of the adhesive layer 160 and also facilitates the peeling of the release layer 170 .

[0073] Traditional anti-reflective films are mostly simple PET films, whose optical and mechanical properties are relatively general, and have deficiencies in transmittance, haze value, adhesion, pencil hardness, steel wool abrasion resistance and other properties.

[0074] The above-mentioned anti-reflective hydrophobic film 100 has good optical properties such as transmittance, haze value, Y value, a* value, b* value, etc. The water contact angle of the above-mentioned anti-reflective hydrophobic film 100 is above 90°, which reduces the adhesion of water droplets on the surface of the fluorosilicone resin film layer 120, ensures visibility when it rains, and avoids the situation where the image of the sequential control operation is not clear on rainy days. In addition, the adhesion, pencil hardness, and steel wool wear resistance of the anti-reflective hydrophobic film 100 of the above-mentioned embodiment are all within the specification value range. The above-mentioned anti-reflective hydrophobic film 100 has good mechanical properties such as adhesion, pencil hardness, and steel wool wear resistance, and the PET protective layer 150 therein has good mechanical properties and excellent anti-peeling effect.
