Description

[0002] China has a vast territory and diverse climate characteristics. Silicone rubber materials (mainly referring to high-temperature vulcanized composite materials and room-temperature vulcanized composite materials) are widely used in the field of high-voltage external insulation. However, with the more extensive application of silicone rubber materials across the country and the world, various problems have emerged in different temperature and humidity environments. In places such as Sichuan, Yunnan, Guangxi, and Guangdong in China, it has been found through investigation that there are phenomena of algae and fungi growing on the surface of external insulation equipment to varying degrees. Since algae, fungi, and bacteria themselves belong to microorganisms, when the environment is suitable, the parasites multiply in large numbers and easily form a symbiotic biofilm, thus affecting the hydrophobic performance, electrical performance, mechanical performance, and physical and chemical properties of the silicone rubber material on the surface of the insulator, increasing the risk of flashover, and endangering the insulation reliability of the external insulation equipment. How to deal with the problem of algae growing on the surface of insulators has become an important task in the field of power transmission and transformation external insulation.

[0003] Currently, for the method of using ultraviolet irradiation to kill algae on the surface of silicone rubber, a device for ultraviolet irradiation on the surface of the insulator silicone rubber needs to be built. Directly using a parallel irradiator to irradiate with parallel light beams on the surface of the insulator cannot quantitatively measure the treatment dose of ultraviolet light, takes a long time, is likely to cause adverse effects on the surrounding environment, and the process of comprehensively killing algae on umbrella-shaped insulators with complex shapes is relatively long.

[0036] Next, with reference to the accompanying drawings and embodiments, the specific embodiments of the present invention will be further described in detail. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0037] As Figure 1 shown, a preferred embodiment of the present invention provides a method for ultraviolet treatment of algae on the silicone rubber surface, including the following steps:

[0038] Measure the growth density of the algal parasites attached to the silicone rubber.

[0039] Place the silicone rubber on a housing provided with a plurality of ultraviolet irradiation lamps 1.

[0040] Turn on the ultraviolet irradiation lamp 1 to emit ultraviolet light to irradiate the algae on the silicone rubber.

[0041] Measure the average irradiation intensity and treatment time of the silicone rubber, and obtain the ultraviolet irradiation dose corresponding to the growth density according to the average irradiation intensity and the treatment time.

[0042] Based on the above technical features, for the method of ultraviolet treatment of algae on the silicone rubber surface, measure the growth density of the algal parasites attached to the silicone rubber, and perform rapid irradiation treatment on the algae by a plurality of the ultraviolet irradiation lamps 1 to achieve the effect of inactivating the algae. By obtaining the average irradiation intensity and treatment time of the silicone rubber, the corresponding ultraviolet irradiation dose is obtained, and the activity change of the algae on the silicone rubber surface after being subjected to a quantitative ultraviolet irradiation is studied, so as to realize the quantitative irradiation dose treatment of the algae on the silicone rubber insulator, which is beneficial to reducing the time required for the algae killing process while ensuring a good algae killing effect.

[0043] In this embodiment, in the step of placing the silicone rubber on a housing provided with a plurality of ultraviolet irradiation lamps 1, specifically:

[0044] Place the silicone rubber inside the housing provided with a plurality of ultraviolet irradiation lamps 1; or place the silicone rubber outside the housing provided with a plurality of ultraviolet irradiation lamps 1, and use the movable cover plate 2 to locally cover the silicone rubber.

[0045] When the silicone rubber is placed inside the housing provided with a plurality of ultraviolet irradiation lamps 1, irradiation treatment of the entire area of the silicone rubber is achieved. When the silicone rubber is placed outside the housing provided with a plurality of ultraviolet irradiation lamps 1, a movable cover plate 2 is used to partially cover the silicone rubber, and irradiation treatment is performed on the local position of the silicone rubber that needs to be treated, forming a contrast with the local position that has not been irradiated, so as to realize the study of the change in the surface properties of the silicone rubber material after being irradiated by ultraviolet rays.

[0046] In this embodiment, in the step of turning on the ultraviolet irradiation lamp 1 to emit ultraviolet rays to irradiate the algae on the silicone rubber, specifically:

[0047] Turn on the ultraviolet irradiation lamps 1 with a plurality of different irradiation directions to emit ultraviolet rays to uniformly irradiate the algae on the silicone rubber. Through the ultraviolet irradiation lamps 1 with a plurality of different irradiation directions, silicone rubber insulators with different structures are adapted to achieve uniform irradiation thereof, ensuring the accuracy of measuring the average irradiation intensity of the silicone rubber.

[0048] In this embodiment, in the step of measuring the average irradiation intensity and treatment time of the silicone rubber, specifically:

[0049] Use a UV-VIS spectrophotometer to obtain the average irradiation intensity of the plane where the silicone rubber is placed, and use a timer to obtain the treatment time required to inactivate the algae, ensuring the validity of the measured data. Among them, the UV-VIS spectrophotometer and the timer are both existing devices, and their specific structures and control methods will not be elaborated here.

[0050] Further, in the step of obtaining the ultraviolet irradiation dose corresponding to the growth density according to the average irradiation intensity and the treatment time, specifically:

[0051] Substitute the average irradiation intensity and the treatment time into the following formula: ultraviolet irradiation dose = average irradiation intensity * treatment time; obtain the ultraviolet irradiation dose corresponding to the growth density. The following gives the approximate corresponding relationship between the growth density of the algae and the ultraviolet irradiation dose that can achieve the algae inactivation effect:

[0052]

[0053] In this embodiment, in the step of measuring the growth density of the algal parasites attached to the silicone rubber, specifically:

[0054] Use a camera with a preset white balance to photograph the surface of the silicone rubber, and combine the image analysis method and the linear fitting formula:

[0055] D = -0.0126Csur 2 +0.1282C sur +1.0049

[0056] where D is the proportion of the G component in the RGB components of the image, and C sur is the algal growth density; the algal growth density on the silicone rubber surface is measured. By photographing the surface image of the silicone rubber, the algal growth density can be quickly obtained through image analysis.

[0057] In this embodiment, the following steps are further included: turning the silicone rubber upside down, placing the silicone rubber on the housing, and performing another irradiation treatment to ensure the accuracy of the measurement results and achieve a better algae-killing effect.

[0058] In summary, the experimental method provided by the embodiment of the present invention performs quantitative ultraviolet irradiation on algae with different growth densities, performs concentrated and rapid irradiation treatment on the silicone rubber surface, achieves the effect of algae inactivation, can study the activity change of algae on the silicone rubber surface after being subjected to quantitative ultraviolet irradiation, and at the same time study the surface property change of the silicone rubber material after being irradiated by ultraviolet rays by controlling the irradiation of different areas.

[0059] As Figure 2 shown, the present invention also provides an ultraviolet treatment test device for algae on the silicone rubber surface, including a housing, and an ultraviolet irradiation lamp 1 and a movable cover plate 2 provided on the housing. The housing includes a top plate 3 and inclined plates 4 provided on both sides of the top plate 3. A plurality of parallelly arranged ultraviolet irradiation lamps 1 are provided on the inner side surfaces of the top plate 3 and the inclined plates 4. The movable cover plate 2 is disposed opposite to the top plate 3, and a sliding structure is provided between the movable cover plate 2 and the housing.

[0060] Based on the above technical features, the ultraviolet treatment test device for algae on the silicone rubber surface can place the silicone rubber with attached algal parasites on the housing, and use the ultraviolet irradiation lamps 1 in multiple different directions to quickly irradiate the algae to achieve the effect of algae inactivation. Sliding the movable cover plate 2 can block the local irradiation light, realizing full irradiation treatment or local irradiation treatment of the silicone rubber, which is beneficial to reducing the time required for the algae-killing process while ensuring a good algae-killing effect, and is convenient for studying the activity change of algae on the silicone rubber surface after being subjected to quantitative ultraviolet irradiation, and studying the surface property change of the silicone rubber material after being irradiated by ultraviolet rays.

[0061] Among them, when the silicone rubber is placed inside the housing provided with a plurality of ultraviolet irradiation lamps 1, irradiation treatment of the entire area of the silicone rubber is achieved. When the silicone rubber is placed outside the housing provided with a plurality of ultraviolet irradiation lamps 1, the moving cover plate 2 is used to partially cover the silicone rubber, and the local position of the silicone rubber that needs to be treated is irradiated, forming a contrast with the local position that has not been irradiated, so as to realize the study of the surface property changes of the silicone rubber material after being irradiated by ultraviolet rays.

[0062] In this embodiment, the device further includes side plates 5 connected to both sides of the inclined plate 4. The moving cover plate 2 straddles between the two side plates 5. The top plate 3, the inclined plate 4, the side plates 5 and the moving cover plate 2 enclose a cavity for accommodating the silicone rubber. The side plates 5 play a supporting role for the top plate 3 and the inclined plate 4 to form a cavity for accommodating the silicone rubber.

[0063] In this embodiment, the sliding structure is arranged between the moving cover plate 2 and the side plates 5 to realize changing the position of the moving cover plate 2 and specifically covering the local irradiation light.

[0064] In this embodiment, the sliding structure includes two relatively arranged L-shaped clamping plates 6. The L-shaped clamping plates 6 are fixed on the corresponding side plates 5. The L-shaped clamping plates 6 extend a convex wall edge towards the middle of the housing. The moving cover plate 2 is located on the convex wall edges on both sides, so that the moving cover plate 2 can move relative to the L-shaped clamping plates 6.

[0065] In this embodiment, a black glue coating 7 for preventing ultraviolet rays is further provided on the inner side surface of the side plates 5, which can reduce the influence of internal ultraviolet rays on the users and improve the safety of the device.

[0066] In this embodiment, the included angles between the inclined plate 4 and the top plate 3 and between the inclined plate 4 and the side plates 5 are both 135°, so as to realize the irradiation of the ultraviolet irradiation lamp 1 in multiple different directions.

[0067] In this embodiment, it further includes a driving power supply 8, a control board 9, a UV-VIS spectrophotometer disposed on the housing, and a display screen 10 for displaying measurement data. The UV-VIS spectrophotometer is electrically connected to the display screen 10, the driving power supply 8 is electrically connected to the control board 9, and each of the ultraviolet irradiation lamps 1 is electrically connected to the control board 9 in a one-to-one correspondence. The control board 9 controls each of the ultraviolet irradiation lamps 1 individually, facilitating the control of the irradiation amount of ultraviolet rays. The UV-VIS spectrophotometer obtains the average irradiation intensity of the plane where the silicone rubber is placed, uses a timer to obtain the treatment time required to inactivate the algae, and displays the measurement parameters through the display screen 10. Among them, the UV-VIS spectrophotometer, the control board 9, and the driving power supply 8 are all existing devices, and their specific structures and control methods will not be elaborated here.

[0068] In summary, the ultraviolet treatment test device for algae on the silicone rubber surface provided by the embodiment of the present invention is small and portable, facilitating on-site treatment of silicone rubber insulators. Moreover, using this device can achieve quantitative irradiation dose treatment of algae on silicone rubber insulators, which is beneficial to reducing the time required for the algae killing process while ensuring a good algae killing effect, studying the activity changes of the algae on the silicone rubber surface after being subjected to quantitative ultraviolet irradiation, and studying the surface property changes of the silicone rubber material after being irradiated by ultraviolet rays.
